The utility model is composed of a power hydraulic device, an auxiliary hydraulic device, an increment oil cylinder, an isolation test device, a check valve, etc. The auxiliary hydraulic device and the power hydraulic device are respectively independent, the auxiliary hydraulic device is provided with a liquid level detection device, and emulsion is used as a usage media, so the pollution of the slurry caused by hydraulic oil is avoided. The utility model has the advantages of high efficiency, small size and simple structure, and can be used as a slurry pump for an ore-dressing process.
Description
The utility model relates to a kind of line transportation pump, and particularly being applicable to has the slurry of being strict with to carry to oil pollution.
The hydraulic diaphragm pump that No. 94231514.6, prior art such as China's patent, though can finish the conveying task of slurry, but because spacer medium is a hydraulic oil, in case isolating glued membrane lost efficacy, hydraulic oil is just lumped together together with slurry, slurry is caused oil pollution,, will influence the technical order of next technological process as using as the beneficiation flowsheet pump.
The purpose of this utility model provides a kind of novel slurry transfer pump, and this pump can not produce oil pollution to slurry body.It is simple in structure, and floor space is little, the efficient height.
The purpose of this utility model is achieved in that two medium hydraulic diaphragm pumps comprise a dynamicliquid pressure device, and an auxiliary hydraulic set is isolated and detection device an increment oil cylinder, four safety check and a control microcomputer for two.The utility model has disposed an auxiliary hydraulic set of being made up of oil pump, relief valve, one-way valve, solenoid valve etc., and auxiliary hydraulic set is connected with the piston cylinder of increment oil cylinder, and provides hydraulic transmission medium to the piston cylinder and the isolation tank epicoele of increment oil cylinder.When isolation tank epicoele liquid reduced, the oil pump of auxiliary hydraulic set can start automatically by microcomputer control, and the flow of liquid that needs to replenish enters in the isolation tank epicoele through solenoid valve, makes barrier film be displaced downwardly to correct position; When isolation tank epicoele liquid increased, solenoid valve was opened under control of microcomputer automatically, and unnecessary liquid just can flow back to auxiliary hydraulic set, thereby had realized automatic liquid supply and tapping, made barrier film can remain on the optimal movement position automatically.
The utility model and prior art following advantage relatively arranged:
1, this equipment not only can be used to general slurry conveying, also can be used as process pump and uses.
2, on auxiliary hydraulic set, be furnished with liquid level sensor, can find in time that barrier film lost efficacy, and prevented the loss of high amount of supplemental liquid.
3, power fluid separates supply with additional emulsified liquid, can significantly reduce the loss of oil pollution and power fluid, reduces operating cost.
4, its monolithic construction brings convenience for installation, maintenance.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is fundamental diagram of the present utility model and constitutional diagram.
Fig. 2 is auxiliary hydraulic set liquid level sensor figure.
Two medium hydraulic diaphragm pumps are made up of six parts:
The dynamicliquid pressure device comprises a table oil pump 1, solenoid valve 4, relief valve 2, cooler 3 and fuel tank, oil purifier etc.
Auxiliary hydraulic set, comprise a table oil pump 10, solenoid valve 9, relief valve 11, one-way valve 12 and by a nonmetal transparent tube 22, two Detecting elements 23, bottom nozzles 24, go up the liquid level sensor that base 26, ball float 25 etc. are formed.Auxiliary hydraulic set is connected with the piston cylinder 8 of increment oil cylinder, provides hydraulic transmission medium to the piston cylinder 8 and isolation tank 18 epicoeles of increment oil cylinder, and adjusts volume pad in the UNICOM chamber by control microcomputer 27.The working medium that auxiliary hydraulic set uses is emulsified liquid.
The increment oil cylinder comprises piston cylinder 8, piston 7, plunger case 5 and piston limit position Detecting element 6.High pressure oil in the plunger case 5 is provided by the dynamicliquid pressure device, and the emulsified liquid in the piston cylinder 8 is provided by auxiliary hydraulic set.
Isolate and detection device, comprise two isolation tanks 18, diaphragm of rubber 19, hollow metal pipe 17 and barrier film Detecting element 15,16.Diaphragm of rubber 19 is divided into epicoele and cavity of resorption with isolation tank 18, and epicoele is connected with auxiliary hydraulic set, and cavity of resorption links to each other with pipeline by safety check 20,21, and barrier film both can guarantee that slurry body did not enter the increment oil cylinder, but transferring power again is pressed into pipeline with slurry.For detecting the position of barrier film 19 in tank body, a side that is positioned at isolation tank 18 epicoeles at barrier film 19 connects a hollow metal pipe 17, in metal tube 17 reciprocating appropriate locations Detecting element 15,16 is set.
Control microcomputer 27 is used for control apparatus by the work of designing program.
When two medium hydraulic diaphragm pumps are worked, at first start oil pump 10, connect solenoid valve 9 then, additional emulsified liquid is charged in the UNICOM chamber on piston cylinder 8 and barrier film 19 tops, make its long-pending constant volume pad that becomes one.The amount that charges into UNICOM's intracavity liquid is to guarantee that the meta that barrier film 19 is in the isolation tank 18 is good, and its barrier film 19 positions are determined by Detecting element 15,16.Liquid make-up just can start oil pump 1 and carry out work after finishing.
Dynamic medium hydraulic oil and promotes piston 7 or be moved to the left to the right in solenoid valve 4 enters a left side or right plunger case 5.Because moving of piston 7, the left chamber in the piston cylinder 8 or the volume in right chamber are changed.Just slurry is sucked when left chamber volume becomes big in the left isolation tank, right chamber volume diminishes simultaneously, just right isolation tank bottom slurry is entered in the pipeline, otherwise slurry is discharged in the left side, and the right side sucks slurry, thereby realizes continuous slurry body.
In the work, when the motion of piston 7 was amesiality, Detecting element 6 can in time feed back to microcomputer 27, and microcomputer can be adjusted piston 7 automatically and get back to desired location.
Auxiliary hydraulic set has disposed liquid level sensor, and it is made up of bottom nozzle 24, nonmetal transparent tube 22, ball float 25, Detecting element 23 and last base 26 etc.The bottom nozzle 24 of this device is connected with the auxiliary hydraulic set casing, and ball float 25 levitating height in pipe is liquid levels height in the case.When liquid in the case reduced, ball float 25 descended thereupon, when ball float 25 descends through Detecting element 23, just had electrical signal to produce, and this signal feed back is given microcomputer, but microcomputer prompting operation person handles.If liquid increases in the case, ball float 25 can pass through the upper detection element, and its situation is the same.Liquid level sensor can make additional medium run off and be in controllable state.
When barrier film 19 lost efficacy, the emulsified liquid liquid level in the auxiliary hydraulic set casing can change, and this variation feeds back to microcomputer 27 by the Detecting element in the liquid level sensor 23, and microcomputer 27 in time prompting operation person is checked, keeped in repair.
Auxiliary hydraulic set separates with the dynamicliquid pressure device, adopts different medium, when barrier film lost efficacy, can not produce a large amount of fluid and run off, and has avoided the pollution of fluid.
