Abstract

The utility model relates to an electric emulsion proportioning device, which is suitable for proportioning emulsion at the underground place of a coal mine having a pressure water resource. The utility model has the purposes of convenient operation, accurate proportioning concentration and continuouse and adjustable operation. The utility model comprises an electric motor, a stepless speed changing device, a cycloid type oil suction pump, a worm speed reducer, a concentration instrument, a one-way valve, a self operated flow control valve, an emulsifier and an emulsifying oil box, wherein the electric motor is connected with the stepless speed changing device in series by a shaft coupler and is connected with the cycloid type oil suction pump through a shaft coupler, an oil suction opening of the cycloid type oil suction pump is connected with the emulsifying oil box, and an oil outlet and an outlet of the self operated flow control valve are connected to an inlet of the emulsifier through the one-way valve; the concentration instrument is arranged on the stepless speed changing device through the worm speed reducer.

Description

Electronic emulsified liquid mixing device

Technical field

The utility model relates to a kind of device that utilizes motor to carry out the emulsion automatic mixing as power source.

Background technology

Emulsion is as the driving medium of support apparatus in coal mine, and the reasonability of its concentration and stability played an important role to performance and the service life that guarantees support apparatus, and " safety regulations in coal mine " clearly regulation concentration of emulsion used should be strict controlled between the 3%---5%.In the market the weak point of existing emulsified liquid mixing device be preparation during emulsion or ratio of precision relatively poor, perhaps concentration is non-adjustable, as utilizes the emulsified liquid mixing device of jet pump principle; Though perhaps concentration of emulsion used can be prepared accurately, its preparation cost is higher again, as utilizes sensor, computer-controlled emulsified liquid mixing device.

Summary of the invention

The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, provides a kind of simple operation, compound concentration is accurate and adjustable continuously, the electronic emulsified liquid mixing device that cost is low, the life-span is long.

The utility model includes motor, buncher, cycloid formula oil scavenge pump, worm reducer, concentration meter, check valve, self-operated flow control valve, emulsifier and emulsion tank.Motor is connected in series with buncher by shaft coupling, is connected with cycloid formula oil scavenge pump through shaft coupling again; The inlet port of cycloid formula oil scavenge pump is connected with emulsion tank, and oil-out is through the outlet of check valve and self-operated flow control valve and be connected on the inlet of emulsifier; Concentration meter is contained on the buncher by worm reducer.

Self-operated flow control valve connects the clear water pipeline.Emulsifier adopts porous damping sheet emulsifier, can improve the preparation quality of emulsion greatly.

The utility model is applicable to that the place that pressure water source is arranged under the coal mine carries out emulsion preparation.Motor drives oil scavenge pump by buncher and draws oil emulsion from emulsion tank, pressure water source mixes in the emulsifier porch with oil emulsion through self-operated flow control valve, behind the height mixing and emulsifying of emulsifier, form certain density, uniform and stable emulsion and discharge from the outlet of emulsifier.The handwheel of regulating buncher can change the output speed of buncher, thereby changes the flow of oil scavenge pump, forms the emulsion of variable concentrations.Buncher concentration meter by the worm reducer band, can contrast concentration meter and regulate the buncher handwheel, just can obtain the emulsion of accurate concentration; Adopt buncher, can obtain the continuous emulsion of concentration value.Turn off the water stop valve, cut off the electricity supply, emulsion preparation work promptly stops.The utility model can make emulsion accurate concentration, that quality is higher, and concentration of emulsion used is adjustable continuously, simple to operation, and cost is low, the life-span is long, greatly reduces working strength of workers.

Among the figure, 1. motor, 2. shaft coupling, 3. buncher, 4. shaft coupling, 5. cycloid formula oil scavenge pump, 6. emulsion tank, 7. self-operated flow control valve, 8. worm reducer, 9. concentration meter, 10. check valve, 11. water stop valves, 12. emulsifiers.

The specific embodiment

Motor 1 drives buncher 3 actions by shaft coupling 2, after buncher 3 slows down, drive cycloid formula oil scavenge pump 5 by shaft coupling 4 again and draw oil emulsion from emulsion tank 6, the oil emulsion of drawing converges in the porch of emulsifier 12 through the pressure clear water of check valve 10 with process self-operated flow control valve 7, by just obtaining certain density emulsion behind the emulsifier 12.Can see the concentration of emulsion used value of buncher 3 when the different rotating speeds intuitively by concentration meter 9.So the handwheel that can contrast concentration meter 9 adjusting bunchers 3 needing to obtain the emulsion of concentration value.Buncher 3 can make the concentration of emulsion adjustable continuously.Self-operated flow control valve 7 has pressure oscillation and impact in the automatic elimination underground mine water supply pipe network, guarantee rate-of flow and the metastable ability of pressure behind the valve, can guarantee the stability of emulsion process for preparation.Check valve 10 can prevent that press water from oppositely passing to pump, thereby avoids the counter-rotating or the damage of pump.Cut off the electricity supply, turn off water stop valve 11, this device promptly quits work.Simple to operation, alleviated working strength of workers greatly.
