plant engineering selecting liquid level detectors for tankscapacitance transmitters or probes are long and cylindrical, usually reach to the bottom of the tank, are topmounted, and require overhead clearance. impedance between the probe and metallic tank wall is an indication of liquid level. designs are available for nonmetallic tanks. compensation can be made if tank walls are not straight. hapter application equipmentif agitation is inadequate, the application rate of the pesticide may vary as the tank is emptied. the two common types of agitation are hydraulic and mechanical. the quantity of flow required for agitation depends on the chemical used. little agitation is needed for solutions and emulsions, but intense agitation is required for wettable powders. agitation tank for chemical reagent xinhaiin a large chemical plant in henan, the corrosion resistance is strong, and the percent abandoned of agitation tank is high, after contrast among several companies, the client chose xinhai agitation tank for chemical reagent. this agitation tank adopts push type spiral impeller, the speed is uniform, which makes the material mixing more even setup tank agitator gearboxes for a long life at low costfigure no. 1 shows a conceptual sketch of an agitator shaft rotating in a tank. arrows are used to show the forces that act on the agitator. forces act downward due to selfload and the weight of product. forces also act upward due to lift generated by the turning paddles or blades (just like a boats propeller pushes it through the water). forces acting sideways occur from any outofbalance motion of the shaft and from the propeller action creating random eddies spinning off the blades. all these forces must be countered through the bearings in the gearbox and those on the shaft. freehanging agitators, unsupported by a bearing at the bottom of the shaft, suffer bending moments from the sideways thrust forces. these moments try to bend the shaft towards the wall of the tank. the bearings in the gearbox take all this side thrust loading. one way to reduce the gearbox radial loading is to install intermediate bearings at the top of the shaft and let them take the sideways and vert see full list on accendoreliability the blades, paddles or propellers are turned fast enough to generate a downward current towards the bottom of the tank. the current fans out when it hits the tank bottom and surges towards the walls. it flows up the walls taking the contents along with it. at the surface of the liquid the current collapses and drops into the middle of the tank where the turning blades again draw it down. the blades are made to turn fast enough to pickup any solid ingredients in the mix. these upward flows are occurring at the same time as the agitator rotates the mixture. when an agitator is mounted in the center of the tank it is best to position three or four baffles evenly spaced around the tank wall. baffle plates down the wall of the tank set up an even flow pattern which removes random eddies generated by the blades and minimises fluctuating loads. the baffles loadup the agitator blades more evenly. the baffles also create eddies that peel off the edges for the full height of the baffle prod see full list on accendoreliability small agitators and mixers are often inserted into the tank at an angle and clamped to the tank wall. when a vertical agitator is required the mounting frame for the agitator must be solid, sturdy and stiff enough to take all the transmitted forces and moments without visibly flexing. suppliers of agitators can advise the sizing and arrangement of mounting frame members to handle the loads taken by their equipment. where an agitator is to go into a metal, opentop tank it is usual to put it on steel beams spanning the tank. compensating plates are welded to the outside of the tank at the top of the wall to stiffen it. steel supporting feet are then welded to the compensating plates and the crossmembers spanning the tank are bolted to the support feet. for plastic tanks the support structure needs to go to the floor and be well anchored and braced to take the flexing forces. for roofed tanks the frame can either be mounted in the same fashion as an open top tank or the frame can be see full list on accendoreliability it is bad practice to expect people to go into a tank to unbolt blades from an agitator shaft so the shaft can be removed. people who go into a confined space are putting their lives at risk. it is better to insure the complete agitator and blade assembly can be removed through the top of the tank without anyone having to go inside. insure the full length of the agitator can be removed without interfering with neighbouring plant along side or above. if a mobile crane cannot access the tank to remove the agitator and gearbox a fixed hoist will need to be installed. see full list on accendoreliability where vapours are generated inside an enclosed stirred tank or vessel it is necessary to provide a seal around the agitator shaft to prevent vapours entering the gearbox through failed shaft seals. the vapour seal comprises a tallsided annulus full of liquid (usually water) with the shaft rising up through the center hole. an inverted dish with long sides extending into the annulus is attached onto the shaft and turns with it. the height of the walls on the inverted dish and annulus are made long enough so the vapour pressure in the tank does not push the liquid out of the vapour seal. the liquid in the seal will become contaminated with the tank vapour and will require occasional replacement and replenishment. see full list on accendoreliability below is listed a number of equipment longevity issues that need to be addressed when selecting and installing tank agitators: 1. access is required to shaft couplings. gearboxes need to bestood up off framework to allow access for hands and tools. 2. select shaft couplings and components that will toleratefluctuating axial loads and vapours from the process. 3. methods to get gearboxes off the agitator and lowered to theground must be designed in at the start. 4. if corrosive chemicals are used in the process it is necessary toaddress materials compatibility issues within the liquid and thevapour space. 5. use of chains and veebelts in the drive arrangement lead totrouble. they get dirty and wear fast. horizontally mounted chains sag and wear sprocket teeth away. repairs become an expensive and difficult job. 6. by installing bearings on the agitator shaft to take the axial and bending forces it is possible to go use a less expensive gearbox than one specially designed for agitato see full list on accendoreliability agitation tank,iron ore, copper ore

process engineering avoid trouble with slurries chemical nov 01, 2006 · as the tank empties the particle size becomes smaller, the filtration rate is slower, and cake quality becomes poorer. eventually, the centrifuge or filter may plug. the root cause of the problem is often oversizing of the feed tank (either too large or too tall for the agitator height). agitation equipment, agitation equipment direct from jiangxi agitation equipment from jiangxi hengchang mining machinery manufacturing co., ltd.. search high quality agitation equipment manufacturing and exporting supplier on alibaba . how to choose a suitable agitation tank for mineral are you curious about how the agitation tank woks? do you want to know how to choose a suitable agitation tank? here is the answer: 16 sec 582 xinhai miningalfa laval yeast management systemsno, our 3in1 agitator does not fit through a normal manhole and must be installed at a separate flange. do you monitor dissolved oxygen (do) into the slurry? no, we do not monitor do in the slurry but measure the yeast propagation based on the drop in °plato. can you recommend the typical agitation speed for a yeast storage tank? agitation,mixing equipment systems manufacturer india,skid agitation systems for mixing, blending, suspending, dispersing, heat transfer etc. impeller selection can be made after pilot plant study. optimization of power requirement considering application. shaft sealing arrangement from stuffing box to mechanical seal ( single or double ) with appropriate buffer fluid arrangement. agitation and mixing wordpress a. in small tanks the impeller can be mounted off center (shaft is moved away from center then tilted in a plane perpendicular to the direction of move) b. in large tanks, the agitator may be mounted in the side of the tank with shaft in horizontal plane but at an angle with radius. c. in large tanks with vertical agitators, swirling can be
