Abstract
The utility model provides a disassembly-and-wash-free filtering device for an underground water supply pipeline of a coal mine. The device comprises water supply pipes, wherein a filter cavity is fixed between the water supply pipes, and a filter vat is arranged in the filter cavity; a first gate valve and a second gate valve are arranged on the water supply pipes at the front and rear ends of the filter cavity respectively; a branch pipe communicated with the filter cavity is arranged at a water inlet end of each water supply pipe; a water inlet end of the branch pipe is arranged at the front end of the first gate valve, and a water outlet end is arranged at the rear end of the filter vat; a drain pipe is arranged at the front end of the filter vat. As the branch pipes are arranged at the water inlet end and rear end of the filter cavity, through the control of the gate valves, the incoming water reversely enters the filter vat from the bottom end of the filter vat through the branch pipes and performs reverse flushing of the filter vat to achieve an aim of automatically cleaning a filter net without disassembling the water supply pipes. Therefore, the device provided by the utility model is convenient to use and improves the filtering effect.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to supply channel under a kind of coal mine and exempts to unpick and wash filter.
Background technology
Colliery downhole equipment as cleaner water be all directly to fetch water nearby, the water quality of down-hole is generally poor, wherein contains a lot of large granular impurities, the shower nozzle that easily causes the wear and aging of instrument and stop up depositing dust facility.For large granular impurity in filtered water, current method is in pipeline junction, to increase screen pack to filter, but existing filter exists following problem:
1. filter used after a period of time, and need to manually open filter taking-up screen pack and carry out installing back again in device after manual cleaning, complex operation, and affect equipment water;
2. in filter, screen pack is to adopt ordinary steel wire to make, and easily corrosion after its use a period of time, causes filter failure, affects equipment water;
3. screen pack place hydraulic pressure is excessive, and flow velocity is fast, poor filtration effect.
Utility model content
The utility model will solve above-mentioned deficiency exactly, provides supply channel under a kind of coal mine to exempt to unpick and wash filter, improves filter effect, and by the water (flow) direction in change filter chamber, reaches the object of automatic cleaning and filtering net.
In order to reach above-mentioned effect, the utility model provides supply channel under a kind of coal mine to exempt to unpick and wash filter, comprises water supply line, in the middle of described water supply line, is installed with filter chamber, in described filter chamber, is provided with filter vat; Be positioned on the water supply line of front and back ends of filter chamber and be respectively equipped with the first gate valve and the second gate valve; The water inlet end of described water supply line is provided with the arm communicating with filter chamber, and the water inlet end of described arm is located at the front end of the first gate valve, the rear end that filter vat is located in water side; The front end of described filter vat is provided with drainpipe.
Further, described arm is provided with the 3rd gate valve, and drainpipe is provided with the 4th gate valve.
Further, the diameter of described filter chamber is larger than the diameter of water supply line.
Further, described filter vat is made by stainless steel, and its sidewall and bottom are equipped with water hole.
During normal water supply, open the first gate valve and the second gate valve, with entering to close the 3rd gate valve and the 4th gate valve, water inlet enters filter chamber from water supply line, then after the filtration by filter vat, equipment is supplied water.After using a period of time, screen pack is stopped up by impurity such as bits and affects while supplying water speed, the first gate valve and the second gate valve are closed, open the 3rd gate valve and the 4th gate valve simultaneously, water inlet enters the back segment of filter chamber from arm, then from carry out the bottom of filter vat from drainpipe draining, its current back flush filter vat, be filtered bucket and filter the bits hold back etc. and discharge from the 4th gate valve, realized the function of automatic cleaning.
The beneficial effects of the utility model have:
1. because the diameter of filter chamber is larger than the diameter of water supply line, thereby the flow velocity while having reduced current through filter chamber has improved the filter effect to impurity in water.
2. the filter vat in the utility model is to adopt 304 high-strength stainless steels to make, and it is corrosion-resistant, has improved service life, and has reduced the workload of regular maintenance.
3. the utility model is provided with arm at the water inlet end of filter chamber and the rear end of filter chamber, by the control of gate valve, make by arm, from the bottom of filter vat, oppositely to enter filter vat into water, and to its back flush, reach and do not take the just object of energy Automatic clearance screen pack of supply channel apart, easy to use, and reduced workload.
4. in water supply line, arrange after this device, solve the attrition to equipment of suspended impurity in the water of down-hole, improve the useful life of equipment; And dustproof water, after filtering, effectively raises the result of use of synthesis dust prevention facility, for Underground working site provides good operating environment, has protected employee's physical and mental health.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
In figure: 1-water supply line, 2-arm, 3-drainpipe, 4-filter vat, 5-filter chamber, 6-1 the first gate valve, 6-2 the second gate valve, 6-3 the 3rd gate valve, 6-4 the 4th gate valve.
The specific embodiment
As shown in Figure 1, under a kind of coal mine, supply channel exempts to unpick and wash filter, comprises water supply line 1, in the middle of described water supply line 1, is installed with the filter chamber 5 larger than the diameter of water supply line 1, in described filter chamber 5, is provided with filter vat 4; Be positioned on the water supply line 1 of front and back ends of filter chamber 5 and be respectively equipped with the first gate valve 6-1 and the second gate valve 6-2; The water inlet end of described water supply line 1 is provided with the arm 2 communicating with filter chamber 5, and the rear end of filter vat 4 is located in front end, the water side that the water inlet end of described arm 2 is located at the first gate valve 6-1; The front end of described filter vat 4 is provided with drainpipe 3.Arm 2 is provided with the 3rd gate valve 6-3, and drainpipe 3 is provided with the 4th gate valve 6-4.
