Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a coal mine filter element cleaning device. Background Technology

[0002] In the process of coal mining and related production operations, various types of mechanical equipment are widely used, and filter elements, as key components to ensure the normal operation of equipment, play a vital role. They can effectively filter impurities in media such as oil and air, preventing these impurities from entering the equipment.

[0003] In existing technologies, filter cleaning requires the following structure;

[0004] Cleaning tank: The cleaning tank is used to hold filter elements and cleaning fluid, providing space for the cleaning process.

[0005] First driving device: drives the filter element to rotate relative to the first cleaning brush, making cleaning more thorough.

[0006] Transmission unit: drives the filter element fixing unit to rotate.

[0007] Spray pipe: The spray pipe is fixedly connected inside the cleaning tank and connected to the water pipe, which can spray water onto the filter element for rinsing.

[0008] Due to the complex structure of filter cartridges, some tiny areas and internal pores are difficult to clean thoroughly, easily leaving impurities and affecting the cartridge's reusability. While simple soaking is relatively convenient, the degree of contact between different parts of the filter cartridge and the cleaning solution varies significantly during soaking. The concentration and duration of contact with the cleaning solution differ between the central area and the part near the container wall, resulting in inconsistent cleaning effects and an inability to guarantee the overall cleanliness of the filter cartridge. This makes it difficult to fully restore the filter's filtration performance and shortens its lifespan. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a coal mine filter element cleaning device, which solves the aforementioned technical problems.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A coal mine filter element cleaning device includes a cleaning box with a lid. Clamping mechanisms are provided on both sides of the inner wall of the cleaning box. A rotating shaft is rotatably mounted through and limited on the cleaning box. A round rod sleeve is slidably mounted on the rotating shaft. A friction block is fixedly mounted on the round rod sleeve. The clamping mechanisms include clamping rods with movable grooves. Two L-shaped top blocks are slidably mounted in the movable grooves of the clamping rods. Extrusion plates are slidably mounted on the sides of the two L-shaped top blocks. An adjusting screw is rotatably sleeved on the upper limit of the extrusion plate. The adjusting screw is threadedly connected to the clamping rod. A filter element body is located between the two clamping mechanisms, and the circumferential surface of the filter element body is in contact with the friction block.

[0012] Preferably, a bearing is fitted on the circumferential surface of the clamping rod, and a limiting baffle is provided on the bearing. The limiting baffle is fixedly installed on the circumferential surface of the clamping rod. The two L-shaped top blocks are both in contact with the inner wall of the bearing. A servo motor is installed on the right side of the cleaning tank via a bracket.

[0013] Preferably, the servo motor is fixedly connected to the rotating shaft via an output shaft, a locking screw is threaded through the round rod sleeve, the locking screw is in contact with the circumferential surface of the rotating shaft, a clamping rod located in the right clamping mechanism is installed through the cleaning tank, and a connecting block is fixedly installed on the side end of the clamping rod.

[0014] Preferably, a hand crank is rotatably mounted through the connecting block, and the connecting block and the hand crank are mutually limited in rotation. The hand crank is rotatably connected to the cleaning box via a thread, and the clamping rod located in the left clamping mechanism is fixedly installed on the inner wall of the cleaning box.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] I. This new type of filter element uses a servo motor to drive a rotating shaft to rotate stably, and the friction block also rotates accordingly. Since the circumferential surface of the filter element body is in contact with the friction block, the friction block will drive the filter element body to rotate during the rotation process. As described in the first step of the working principle, when the prepared chemical solution is placed in the cleaning tank and the filter element body is soaked, the rotation of the filter element body allows all parts of it to have a chance to fully contact the chemical solution, avoiding cleaning dead corners. Compared with the traditional static soaking cleaning method, the uniformity of cleaning is greatly improved, thereby effectively improving the cleaning effect.

[0017] Second, this new device, through the setting of two sets of clamping mechanisms, allows the user to easily disassemble and replace bearings when it is necessary to replace bearings of different sizes to adapt to filter cartridge bodies of different diameters. This is achieved by rotating the adjusting screw (as described in step two of the working principle). Furthermore, the locking screw installed on the round rod sleeve is in contact with the circumferential surface of the rotating shaft. When the locking screw is loosened, the round rod sleeve can slide on the circumferential surface of the rotating shaft, which can flexibly adjust the position of the friction block. This allows the device to clean filter cartridge bodies of different sizes, greatly improving the applicability of the device. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in view of the problems existing in the prior art, the overall idea is as follows: This utility model provides a coal mine filter element cleaning device, including a cleaning box 21, and a box cover 28 on the cleaning box 21. The box cover 28 can prevent the cleaning liquid from splashing out during the cleaning process, and at the same time prevent external dust and other impurities from falling into the cleaning box 21 and affecting the cleaning effect, thus ensuring a relatively closed and clean cleaning environment.

[0028] The inner walls of the cleaning tank 21 are equipped with clamping mechanisms on both sides. The clamping mechanisms are mainly used to firmly fix the filter element body 27, ensuring that the filter element will not be displaced during the cleaning process and ensuring the stability of the cleaning. A rotating shaft 23 is mounted through the cleaning tank 21 and is limited to rotate. The rotating shaft 23 provides the rotation basis for driving the filter element to rotate. Its limited rotation installation method ensures the stability and accuracy of the rotation process. A round rod sleeve 25 is slidably mounted on the rotating shaft 23. The round rod sleeve 25 can slide flexibly on the rotating shaft 23 and can adjust its position according to the different lengths of the filter element, enhancing the applicability of the device. A friction block 26 is fixedly mounted on the round rod sleeve 25. When rotating, the friction block 26 can contact the circumferential surface of the filter element body 27. The friction force drives the filter element body 27 to rotate, so that the filter element rotates in the cleaning solution and achieves a more uniform cleaning effect.

[0029] The clamping mechanism includes a clamping rod 11 with a movable groove 16 inside. The movable groove 16 provides space for the movement of the L-shaped top blocks 12, allowing the clamping mechanism to be flexibly adjusted according to different needs. Two L-shaped top blocks 12 are slidably installed within the movable groove 16 of the clamping rod 11. The two L-shaped top blocks 12 cooperate with each other, and their movement allows for the fixing and loosening of the bearing 15, thus meeting the installation requirements of filter elements of different diameters. Squeezing plates 13 are slidably installed on the sides of the two L-shaped top blocks 12. The squeezing plates 13 can convert the rotational motion of the adjusting screw 14 into pushing or pulling motion on the L-shaped top blocks 12, thereby achieving the desired adjustment. The precise control of the position of the L-shaped top block 12 is achieved by rotating the upper limit sleeve of the extrusion plate 13 with an adjusting screw 14. The adjusting screw 14 is threadedly connected to the clamping rod 11. By rotating the adjusting screw 14, the position of the extrusion plate 13 can be easily adjusted using the principle of threaded connection, thereby controlling the fixed state of the L-shaped top block 12 and the bearing 15. The operation is simple and convenient. A filter element body 27 is provided between the two sets of clamping mechanisms. The circumferential surface of the filter element body 27 is in contact with the friction block 26. This structural design ensures that the friction block 26 can effectively drive the filter element body 27 to rotate, so that the filter element can fully contact the cleaning fluid during the cleaning process.

[0030] A bearing 15 is fitted onto the circumferential surface of the clamping rod 11. The bearing 15 not only reduces the friction of the filter element body 27 during rotation, making its rotation smoother, but also adapts to filter elements of different diameters, enhancing the versatility of the device. A limiting baffle 17 is provided on the bearing 15, which can prevent the bearing 15 from shifting in the axial direction, ensuring that the bearing 15 is always in the correct installation position and improving the stability of the entire device. The limiting baffle 17 is fixedly installed on the circumferential surface of the clamping rod 11. The two L-shaped top blocks 12 are both in contact with the inner wall of the bearing 15. This contact method allows the L-shaped top blocks 12 to stably fix the bearing 15, ensuring that the bearing will not loosen during the cleaning process. A servo motor 22 is installed on the right side of the cleaning tank 21 via a bracket. The servo motor 22 serves as the power source for the entire device, providing stable and continuous power to ensure the normal operation of the device.

[0031] The servo motor 22 is fixedly connected to the rotating shaft 23 via the output shaft. This connection method allows the power of the servo motor 22 to be efficiently transmitted to the rotating shaft 23, driving the rotating shaft 23 and its components to rotate stably. A locking screw 24 is threaded through the round rod sleeve 25. The locking screw 24 can firmly fix the round rod sleeve 25 at any position on the rotating shaft 23, ensuring the stability of the position of the friction block 26 during the cleaning process and ensuring the consistency of the cleaning effect. The locking screw 24 is in contact with the circumferential surface of the rotating shaft 23. The clamping rod 11 located in the right clamping mechanism is installed through the cleaning box 21, and a connecting block 18 is fixedly installed on the side end of the clamping rod 11. The connecting block 18 plays the role of connection and transmission, transmitting the movement of the hand crank 19 to the clamping rod 11, realizing the movement of the clamping rod 11.

[0032] A hand crank 19 is rotatably mounted through the connecting block 18. The hand crank 19 provides a convenient operating component for the operator. By rotating the hand crank 19, the position of the clamping rod 11 can be easily adjusted. The connecting block 18 and the hand crank 19 are limited in rotation. The hand crank 19 is rotatably connected to the cleaning tank 21 by a thread. This design of limited rotation and threaded connection ensures that when the hand crank 19 is rotated, it can both drive the connecting block 18 and the clamping rod 11 to move, while ensuring that the hand crank 19 itself does not rotate arbitrarily, which is convenient for the operator to control precisely. The clamping rod 11 located in the left clamping mechanism is fixedly installed on the inner wall of the cleaning tank 21. The fixed clamping rod 11 on the left and the movable clamping rod 11 on the right cooperate with each other to stably clamp the filter element body 27, ensuring that the filter element will not shake during the cleaning process.

[0033] Working principle:

[0034] The first step, when cleaning filter elements used in coal mining, is to use chemical cleaning agents. Select a suitable chemical agent based on the type of contaminant, such as citric acid or sodium hypochlorite. Place the prepared chemical solution into the cleaning tank 21, and then immerse the filter element body 27 inside the cleaning tank 21 for 2-6 hours. During immersion, the filter element body 27 needs to be secured. The user can do this by turning the hand crank 19, which, through the threaded connection between the hand crank 19 and the cleaning tank 21, can move the filter element body 27 towards the cleaning tank 21. Move to the right, and then through the limiting rotation connection between the hand crank 19 and the connecting block 18, the hand crank 19 can move the connecting block 18 without rotating. At this time, the connecting block 18 drives the clamping rod 11 in the right clamping mechanism to move. At this time, the two clamping mechanisms separate, and the left end of the filter element body 27 is brought into contact with the circumferential surface of the bearing 15 in the left clamping mechanism. There is a certain friction between the bearing 15 and the filter element body 27, which can fix the filter element body 27 and the outer ring of the bearing 15. Then the user can... Reverse the hand crank 19 to tightly engage the bearing 15 on the right clamping mechanism with the right side of the filter element body 27. Then, start the servo motor 22, which drives the rotating shaft 23, the round rod sleeve 25, and the friction block 26 to rotate via the output shaft. The friction block 26 then drives the filter element body 27 to rotate, allowing it to rotate within the prepared chemical solution and contact it more evenly. This novel design achieves stable rotation of the rotating shaft 23 by starting the servo motor 22, thus enhancing friction... The circular block 26 also rotates. Since the circumferential surface of the filter element body 27 is in contact with the friction block 26, the friction block 26 will drive the filter element body 27 to rotate during the rotation. As described in the first step of the working principle, when the prepared chemical solution is put into the cleaning tank 21 and the filter element body 27 is soaked, the rotation of the filter element body 27 allows all parts of it to have a chance to fully contact the chemical solution, avoiding cleaning dead corners. Compared with the traditional static soaking cleaning method, the uniformity of cleaning is greatly improved, thereby effectively improving the cleaning effect.

[0035] The second step involves cleaning filter cartridge bodies 27 of different sizes. When the bearing 15 needs to be replaced, the user rotates the adjusting screw 14. Through the threaded connection between the adjusting screw 14 and the clamping rod 11, the adjusting screw 14 can move the extrusion plate 13. At this time, the extrusion plate 13 separates from the two L-shaped top blocks 12, and the two L-shaped top blocks 12 also separate from the inner wall of the bearing 15. The bearing 15 can then be removed from the circumferential surface of the clamping rod 11. Then, the corresponding bearing 15 can be replaced according to the required size. Afterward, rotating the adjusting screw 14 in the opposite direction will push the two L-shaped top blocks 12 toward their respective ends, thereby fixing the bearing 15. The clamping rod 11 on the right side can move to accommodate filter cartridge bodies 27 of different lengths. The rotating shaft 23 slides against the round rod. The sleeves 25 are fixed together by locking screws 24. When the locking screws 24 are loosened, the round rod sleeve 25 can slide on the circumferential surface of the rotating shaft 23, thereby controlling the position of the friction block 26. With the two sets of clamping mechanisms, when it is necessary to replace the bearings 15 of different sizes to adapt to the filter body 27 of different diameters, the user can rotate the adjusting screw 14 (as described in the second step of the working principle) to facilitate the disassembly and replacement of the bearings 15. Furthermore, the locking screws 24 installed on the round rod sleeve 25 are in contact with the circumferential surface of the rotating shaft 23. When the locking screws 24 are loosened, the round rod sleeve 25 can slide on the circumferential surface of the rotating shaft 23, which can flexibly adjust the position of the friction block 26. This allows the device to clean filter bodies 27 of different sizes, greatly improving the applicability of the device.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
