TECHNICAL FIELD

[0001] The utility model relates to coal mine drainage technical field, concretely is a diaphragm pump multi -interface water suction pipeline structure. BACKGROUND

[0002] Coal mine water disaster is one of five natural disasters (water, fire, gas, coal dust, roof) in coal mine. If the accumulated water is not discharged in time, it will cause great threat to the safety production of the whole coal mine. Effective drainage measures can keep the working place in the mine safe and dry, solve the accumulated water problem, thereby effectively improving the work efficiency of the miners and making the whole production process more smooth.

[0003] At present, when the diaphragm pump is used for drainage in the coal mine, under the action of water flow, coal cinder and the like are easy to cause accumulation on the surface of the filter cartridge. Once accumulated, not only the drainage efficiency is affected, but also the pump may be blocked, which will cause unnecessary property loss. UTILITY MODEL CONTENTS

The structure is provided with rotatable cleaning rods on the outer side wall of the filter cartridge, which can effectively avoid the accumulation of coal cinder and the like on the surface of the filter cartridge, reduce the probability of pump blocking, and make the structure more stable and reliable in application.

[0005] To solve the above technical problem, the technical scheme of the utility model is as follows:

[0006] A diaphragm pump multi -interface water suction pipeline structure, comprising a water suction part and a filter part.

[0007] The water suction part comprises a water suction pipeline. One end of the water suction pipeline is communicated with a main water suction connector. The side surface of the water suction pipeline is communicated with a plurality of first water suction connectors which are linearly arranged along the axial direction. A main water suction pipe is connected to the main water suction connector. The two ends of the main water suction pipe are respectively connected to the diaphragm pump and the main water suction connector through sealing plugs. Each first water suction connector is connected to a water suction pipe through a valve. The valve and the first water suction connector are sealed and fixed through a flange. The two ends of the water suction pipe are respectively connected to the valve and a second water suction connector through sealing plugs.

[0008] The filter part comprises a filter cartridge. One end of the filter cartridge is communicated with the second water suction connector, which is connected to the main water suction pipe of the water suction part. A waterproof motor is fixedly installed at the end of the filter cartridge away from the second water suction connector. A rotating frame is concentrically connected to the rotating shaft of the waterproof motor and located outside the filter cartridge. Two symmetrical cleaning rods are connected to the rotating frame. The cleaning rods are closely arranged on the outer side wall of the filter cartridge.

[0009] Adopting the above scheme, the structure can effectively avoid the accumulation of coal cinder and the like on the surface of the filter cylinder, reduces the probability of pump choking, and makes the structure more stable and reliable in application.

[0010] As a preferred embodiment of the multi-interface water suction pipeline structure of the diaphragm pump, the filter cylinder is only provided with a plurality of uniformly distributed filter holes on the side wall, and the cleaning rods pass through all the filter holes during rotation and cleaning.

[0011] Adopting the above scheme, in order to ensure that the cleaning rods can clean all the filter holes, the rotating frame is driven to rotate by the waterproof motor, so as to drive the two cleaning rods to rotate, thereby reciprocally cleaning the surface of the filter cylinder.

[0014] As a preferred embodiment of the multi-interface water suction pipeline structure of the diaphragm pump, the valve is a shut-off valve, specifically a gate valve, a stop valve, a plug valve, a ball valve, a butterfly valve or a diaphragm valve.

[0015] Adopting the above scheme, in order to improve the flexibility of the valve application, the shut-off valve with the functions of cutting off or stopping is used to control the opening or closing of water suction.

[0016] As a preferred embodiment of the multi-interface water suction pipeline structure of the diaphragm pump, the inside of the water suction pipeline is reinforced and supported by a plurality of horizontally arranged supports.

[0017] Adopting the above scheme, in order to strengthen the internal structure of the water suction pipeline, the supports are used for horizontal support, thereby improving the overall pressure resistance and durability.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1 to 7 As shown, a multi-port suction pipe structure for a diaphragm pump includes a suction section 1 and a filtration section 2. The suction section 1 includes a suction pipe 3, one end of which is connected to a main suction connector 4. Multiple branch suction connectors 5 are linearly arrayed along the axial direction of the suction pipe 3. A main suction pipe 6 is connected to the main suction connector 4, and both ends of the main suction pipe 6 are sequentially press-fitted to the diaphragm pump and the main suction connector 4 via sealing plugs. Each branch suction connector 5 is connected to a branch suction pipe 8 via a valve 7. The valve 7 and the branch suction connector 5 are sealed and fixed by a flange. Both ends of the branch suction pipe 8 are sealed by sealing plugs. The filter section 2 includes a filter cylinder 9, one end of which is connected to the second suction connector 10, which is connected to the main suction pipe 6 of the suction section 1. A waterproof motor 11 is fixedly installed inside the filter cylinder 9 at the end furthest from the second suction connector 10. A rotating frame 12 located on the outside of the filter cylinder 9 is concentrically connected to the shaft of the waterproof motor 11. Two symmetrical cleaning rods 13 are connected to the rotating frame 12, which are close to the outer wall of the filter cylinder 9. Both the main suction pipe 6 and the second suction pipe 8 are transparent water pipes with internal steel wire. This structure, by installing rotatable cleaning rods 13 on the outer wall of the filter cylinder 9, effectively prevents the accumulation of coal slag and other contaminants on the surface of the filter cylinder 9, reducing the probability of pump stalling and making it more stable and reliable in application.

[0035] like Figure 7 As shown, the filter cylinder 9 has multiple evenly distributed filter holes 14 on its side wall. The cleaning rod 13 will pass through all the filter holes 14 when it rotates to clean. In order to ensure that the cleaning rod 13 can clean all the filter holes 14, the waterproof motor 11 drives the rotating frame 12 to rotate, thereby driving the two cleaning rods 13 to rotate, and thus repeatedly cleaning the surface of the filter cylinder 9.

[0036] like Figure 6 As shown, a vertically mounted stand 15 is also fixed on the second water suction connector 10, and two parallel bottom rods 16 are fixed on the stand 15. In order to ensure the normal rotation of the cleaning rod 13, by setting the stand 15 and the bottom rods 16, the bottom rods 16 can completely support the filter cylinder 9 and keep it in a suspended state, thereby ensuring that the cleaning rod 13 can rotate normally.

[0037] Valve 7 is a shut-off valve, specifically a gate valve, globe valve, plug valve, ball valve, butterfly valve, or diaphragm valve. To improve the flexibility of valve 7's application, a shut-off valve with shut-off or cut-off function is used to control the opening or closing of water intake.

[0038] like Figure 4 As shown, the internal structure of the water suction pipe 3 is reinforced and supported by multiple horizontally arranged supports 17. In order to strengthen the internal structure of the water suction pipe 3, supports 17 are used for lateral support, thereby improving the overall pressure resistance and durability.

[0039] The working principle of this utility model:

[0040] Before application, place the filter part 2 in a water pit in the coal mine and place the water absorption part 1 on the ground.

[0041] When in use, the diaphragm pump is started to draw water from the water pit, and the waterproof motor 11 is started simultaneously, and all valves 7 are opened. When pumping water, the waterproof motor 11 drives the rotating frame 12 to rotate, which in turn drives the two cleaning rods 13 to rotate, thereby repeatedly cleaning the surface of the filter cylinder 9. This effectively prevents coal slag and other materials from accumulating on the surface of the filter cylinder 9, reduces the probability of pump blockage, and makes it more stable and reliable in use.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
