Therefore, the whole system of the pump can work steadily, having the advantages of small noise, cylinder grinding prevention and oil emulsification prevention; therefore, the single fine grain slurry can be discharged, and the problems of discharging and transportation of the mixed slurry with big block material are solved.

Description

Combined slurry pump

The utility model relates to a kind of slurry pump, the multi-cylinder double-action combined type slurry pump of the mud of forming especially for single granularity or different grain size.

Power plant, mine, chemical industry, construction industry all need Yi Shui, solid two-phase flow mode, discharge solid material with pipeline transport, because operating mode difference, discharging, haulage device are required also to be not quite similar, require the mud emission equipment of single fine grit composition as the mine, and the mud that power plant requires the discharging different grain size to form, building industry will be carried fine sand, the cement slurry of single granularity sometimes, will transport sometimes to contain the mixing mud that fine sand, cement and stone are formed.And at present high pressure, high concentration slurry haulage device, all be to carry out the preceding transportation of forming the fine grit slip of pump, combination grain fully, particularly contain the slip transportation of bulk materials, and, in the fine grit discharging process, adopt mechanical transmission, exist oil, water, solid phase and mix, grind shortcoming such as cylinder, oily emulsification, vibrating noise be big.

Task of the present utility model provides a kind ofly can carry out the conveying of single fine grit slip, can carry the combination slurry pump that contains piece material combination grain slip again.And will overcome oil, water, solid phase and mix, grind disadvantage such as cylinder, oily emulsification, vibrating noise be big, also to reach the purpose that can control and regulate mud pressure and flow.

The utility model is achieved in that combined type slurry pump work system comprises: hydraulic power unit, double-acting hydraulic cylinder, barrier film jar, check clack box and slurry jar, piece material feeding machine, oil pipe, slip pipeline, hydraulic power unit by oil pipe to beidirectional oil hydraulic cylinder supply pressure oil, realization is power-driven system work with pressure oil, and controls the pressure and the flow of mud by regulating oil pressure and flow.The outlet of beidirectional oil hydraulic cylinder two ends is hinged with two table oil water separation devices respectively, and the utility model adopts special barrier film jar.Jar is made up of upper tank body and lower tank two-part, and clamping the diaphragm of rubber between upper guard board with holes and following backplate and two backplates between the upper and lower tank body.Diaphragm of rubber is with oil, water separation and be subjected to the oil pressure effect and phugoid motion between two backplates, thereby plays the effect of taking out, putting mud.The outlet of barrier film below connects the check clack box, and the import of check clack box links to each other with the slurry jar, and the other end communicates with the mud outlet conduit.The feeding machine that adds bulk materials is installed, to realize that utilizing fine grit mud is the purpose of media discharge bulk materials on the mud outlet conduit.

The utility model is because working pressure oil is power source, so stable working, more mechanically operated noise reduces greatly; Owing to use special barrier film jar transferring power, and oil and mud are separated, avoided oil, water, the mixed oily emulsification that causes of solid phase, ground problem such as cylinder; Owing to will add on the pipeline that the feeding machine of piece material is installed in discharging fine grit mud behind the pump, make native system can realize discharging single fine grit mud, also can discharge the mud of combination grain, solved the problem that unsolved so far combination grain slurry is carried.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is a fundamental diagram of the present utility model.

Fig. 2 is a schematic diagram of structure of the present utility model.

Fig. 3 is the schematic diagram of structure of feeding machine system.

In conjunction with Fig. 1, Fig. 2, hydraulic power unit (1) produces the oil with certain pressure and flow, by oil pipe and selector valve, alternately transfers to the piston of oil hydraulic cylinder (2) both sides, make piston reciprocates, the specification of oil hydraulic cylinder (2) is according to flow, and pressure is selected, and desirable internal diameter is 150 to 300 millimeters, as with one or two oil hydraulic cylinders, the discharging of can pulsing for making the discharging steady and continuous, is got three or three above oil hydraulic cylinder parallel connections.Two side outlets of oil hydraulic cylinder (2) respectively connect a barrier film jar (3), as three oil hydraulic cylinder parallel operations, then need six barrier film jars (3), and the specification of barrier film jar (3) should adapt with the specification of oil hydraulic cylinder (2).The barrier film of barrier film jar (3) is under hydraulic pressure, and mud is taken out, put to rippling.Barrier film jar (3) is connected with clack box (4), in the clack box (4), in the import and the outlet of mud check valve is housed respectively.When barrier film jar (3) is in the suction journey under oil hydraulic cylinder (2) effect, single granularity mud is drawn onto the clack box (4) from slurry jar (5), and enter below the barrier film of barrier film jar (3), because the effect of clack box (4) outlet check valve, the mud in the outlet conduit can not flow backwards at this moment; When barrier film jar (3) when being in scheduling, the mud in barrier film jar (3) and the clack box (4) is discharged among the outlet conduit A, and is same, because the effect of clack box (4) import check valve, this moment, mud can not flow backward to slurry jar (5).The barrier film jar (3) of oil hydraulic cylinder (2) both sides is subjected to the domination of oil hydraulic cylinder (2) reciprocating motion of the pistons, inhaling journey and scheduling hockets, the clack box of both sides (4) also respective quadrature has so far been finished the task of discharging fine grit mud for the single fine grit mud of dispatch in pipe A.

In conjunction with Fig. 3: single fine grit mud is discharged among the export pipeline A, and this moment, mud had certain pressure and flow velocity.The feeding machine system (6) that adds the piece material is installed on pipeline A, in the time of need in fine grit mud, adding bulk materials, open inlet valve (9) and relief valve (10) earlier, close outlet valve (11), bulk materials is packed in the feeding machine cylindrical shell (7), after filling, screened stock flows out from relief valve (10), close inlet valve (9) and relief valve (10) then, open outlet valve (11), start screw(-type) feeder (8), bulk materials is discharged in the pipe A mud, utilize fine grit mud to be medium, the piece material is mixed transferring out, play the effect of combination grain slurry pump.

The utility model all system has reasonably utilized double-acting hydraulic cylinder (2), clack box (4), feeding machine system existing devices such as (6), used barrier film pot type oily-water seperating equipment, make easily manufacturedly, cost reduces, and reaches the effect that stable working, vibrating noise are low, do not grind cylinder.Adjust hydraulic pressure as required, just can control mud pressure and flow, pressure can be at 0～60kg/cm ², flow can be at 0～100m ³Adjust in/h the scope.Both can make simultaneously single fine grit slurry pump, again can be as the combination grain slurry pump, discharging granularity d ₀≤ D 1/5, effluent concentration C=0～70%.
