Description

Technical Field

[0001] The present application relates to the technical field of filter element cleaning, and in particular to an emulsion pump adaptive backwash filter element device. Background Art

[0002] Emulsion pumps play a key role in coal mining and various industrial applications. Their primary purpose is to provide the high-pressure emulsion required for hydraulic support systems. Through their precise reciprocating motion, these pumps ensure the stable operation of hydraulic supports, supporting the heavy pressures of the working environment.

[0003] To maintain the purity of the emulsion and the effectiveness of the system, emulsion pump filter devices are widely used in emulsion supply systems. These devices filter out impurities and particles in the emulsion, ensuring the cleanliness and efficient operation of the hydraulic system.

[0004] However, traditional filter cartridges often become clogged after prolonged use due to the accumulation of impurities, requiring regular removal, cleaning, or replacement of the filter cartridge to maintain its filtration efficiency. This process is not only time-consuming and labor-intensive, but can also affect the lifespan and efficiency of the equipment due to improper operation. Utility Model Content

[0008] outer cylinder;

[0009] The inner cylinder is placed inside the outer cylinder, and the outer cylinder and the inner cylinder are connected through the filter material;

[0010] an emulsion inlet pipe, mounted on the outer cylinder, into which emulsion is introduced, and provided with a first control valve for controlling the on-off of the emulsion pipe;

[0015] Optionally, the flushing member includes:

[0016] A flushing pipe is connected to the fixing seat, and a limiting ring is installed on the flushing pipe;

[0017] A rotating ring is sleeved on the flushing pipe, and the rotating ring and the flushing pipe are rotatably matched;

[0018] a nozzle, mounted on the rotating ring, with an opening of the nozzle arranged obliquely, and the nozzle communicating with the interior of the flushing pipe;

[0019] A reset spring is sleeved on the flushing pipe and located between two adjacent limit rings, and is used for resetting the rotating ring to an initial position.

[0020] Optionally, a plurality of liquid outlet holes are provided on the flushing pipe, and the nozzle is connected to the liquid outlet holes through the rotating ring.

[0021] Optionally, an arc surface for reducing the rotation resistance of the nozzle is provided at one end of the nozzle away from the rotating ring, and the center of the arc surface is located on a side of the arc surface close to the rotating ring.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Under normal operating conditions, emulsion enters the device through the emulsion inlet pipe. After being filtered by the filter material, the clean emulsion flows out of the inner tube outlet. The flow rate detection unit detects the emulsion flow rate at the inner tube outlet. When the emulsion flow rate is lower than the set value, it indicates that the filter element needs to be cleaned. When the filter element needs to be cleaned, cleaning fluid is intermittently introduced through the second control valve. The cleaning fluid is sprayed through the nozzle of the flushing assembly to flush the filter material. The wastewater after flushing is discharged through the cleaning fluid outlet pipe. During the cleaning process, the fourth control valve is closed to prevent the cleaning fluid from entering the emulsion system. After cleaning is completed, the normal flow of the emulsion is restored under the control of the first and fourth control valves.

[0028] After the cleaning liquid enters the flushing pipe, it is sprayed from the outlet through the rotating ring and into the nozzle. During the spraying process, the recoil force of the spray pushes the nozzle to move, achieving full flushing of the filter material. During this movement, the nozzle compresses the return spring. Since the cleaning liquid flows into the flushing pipe intermittently, when the flow stops, the return spring's elastic force pushes the nozzle back into place, thereby facilitating the nozzle's reciprocating motion and expanding the cleaning range.

[0033] The following is combined with Figure 1-Figure 2 This application is described in further detail.

[0034] The embodiment of the present application discloses an emulsion pump adaptive backwash filter device.

[0035] An emulsion pump adaptive backwash filter element device comprises an outer cylinder 1, an inner cylinder 2, an emulsion inlet pipe 3, a cleaning liquid inlet pipe 4, a cleaning liquid outlet pipe 5, a fourth control valve 6 and a flushing component 7.

[0036] The outer cylinder 1 is a cylindrical structure that houses the inner cylinder 2 and the filter material. The outer cylinder 1 can be made of stainless steel, plastic, or other corrosion-resistant materials. The inner cylinder 2, located within the outer cylinder 1, also has a cylindrical structure. The space between the inner cylinder 2 and the outer cylinder 1 is filled with filter material, which can be activated carbon, ceramic, wire mesh, or other filter materials.

[0037] The emulsion inlet pipe 3 is mounted on the outer cylinder 1 and is used to introduce the emulsion into the device. A first control valve 31 is provided on the inlet pipe to control the on and off of the emulsion.

[0038] The cleaning liquid inlet pipe 4 is mounted on the inner cylinder 2 and is used to intermittently introduce cleaning liquid into the device. A second control valve 41 is provided on the cleaning liquid inlet pipe 4 to control the on-off of the cleaning liquid.

[0039] The cleaning liquid outlet pipe 5 is also installed on the outer cylinder 1 for discharging waste water generated during the cleaning process. A third control valve 51 is provided on the liquid outlet pipe for controlling the discharge of waste water.

[0040] The fourth control valve 6 is mounted on the inner tube 2 and is used to control the on and off of the inner tube 2. The fourth control valve 6 is located between the cleaning liquid inlet pipe 4 and the emulsion liquid inlet pipe 3.

[0041] The flushing assembly 7 is located inside the inner tube 2 and includes a fixing seat 71 connected to the cleaning liquid inlet pipe 4 and a flushing member 72 for flushing the filter material.

[0042] A cavity for the flow of cleaning liquid is provided inside the fixing seat 71 , a liquid inlet connected to the cleaning liquid inlet pipe 4 is provided on the side wall, and a liquid outlet connected to the flushing pipe 721 is provided at the end.

[0043] The flushing member 72 includes a flushing tube 721 , a rotating ring 722 , a nozzle 723 and a return spring 724 .

[0044] The flushing pipe 721 is connected to the fixed seat 71 and is threadedly connected to the liquid outlet of the fixed seat 71. A stop ring 7212 is detachably mounted on the flushing pipe 721 to limit the position of the rotating ring 722. In the embodiment of the present application, the stop ring 7212 is threadedly connected to the flushing pipe 721 for easy maintenance and replacement. The flushing pipe 721 is provided with several liquid outlets.

[0045] The rotating ring 722 is sleeved on the flushing pipe 721 and rotates with the flushing pipe 721 to realize the rotating flushing of the nozzle 723. The rotating ring 722 is located between two adjacent limiting rings 7212. The stroke of the rotating ring 722 is adjusted by the two adjacent limiting rings 7212.

[0046] Nozzle 723 is mounted on rotating ring 722. Its opening is tilted and connected to the interior of flushing tube 721, spraying cleaning fluid. Nozzle 723 is connected to liquid outlet 7211 via rotating ring 722. During the spraying process, the recoil force of the spray pushes nozzle 723 to move, achieving omnidirectional flushing of the filter material.

[0047] An arc surface is provided at one end of the nozzle 723 away from the rotating ring 722 for reducing the rotation resistance of the nozzle 723 , and the arc center is located at the side of the arc surface close to the rotating ring 722 .

[0048] A positioning block 7213 is provided on the fixing seat 71 , and a positioning groove for inserting the positioning block 7213 is provided on the inner cylinder 2 to ensure the correct position of the flushing pipe 721 .

[0049] A flow detection unit 8 is provided at the liquid outlet of the inner cylinder 2 for monitoring the flow of the emulsion to determine whether the filter element needs to be cleaned.

[0050] The implementation principle of an emulsion pump adaptive backwash filter element device according to an embodiment of the present application is as follows: under normal working conditions, the emulsion enters the interior of the device through the emulsion inlet pipe 3, and after being filtered by the filter material, the clean emulsion flows out from the liquid outlet end of the inner cylinder 2. The emulsion flow rate at the liquid outlet end of the inner cylinder 2 is detected by the flow detection unit 8. When the emulsion flow rate is lower than the set value, it means that the filter element needs to be cleaned. When the filter element needs to be cleaned, the cleaning liquid is intermittently introduced through the second control valve 41, and the cleaning liquid is sprayed through the nozzle 723 of the flushing component 7 to flush the filter material. The waste water after flushing is discharged through the cleaning liquid outlet pipe 5. During the cleaning process, the fourth control valve 6 is closed to prevent the cleaning liquid from entering the emulsion system. After cleaning is completed, the normal flow of the emulsion is restored through the control of the first control valve 31 and the fourth control valve 6.

[0051] After the cleaning liquid enters the flushing tube 721, it is sprayed from the outlet of the flushing tube 721 and enters the nozzle 723 through the rotating ring 722. As the nozzle 723 sprays liquid, the recoil force of the spray pushes the nozzle 723 to move, achieving all-round flushing of the filter material. During this movement, the nozzle 723 presses against the return spring 724. Since the cleaning liquid flows into the flushing tube 721 intermittently, the elastic force of the return spring 724 pushes the nozzle 723 back to its original position when the flow of cleaning liquid stops, thereby facilitating the reciprocating motion of the nozzle 723 and expanding the cleaning range.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
