Description

Technical Field

[0001] The utility model relates to the technical field of filter screen cleaning, in particular to a pneumatic filter screen cleaning device. Background Art

[0002] A basket filter, also known as a blue filter, is a leader among filters. It has higher technical requirements than other filters and is mainly used on pipelines to process high-precision liquids in the pipe. This filter is an indispensable pipeline accessory in industrial production. Installed on the pipeline, it can filter out solid impurities in the fluid, ensure the normal operation of the pipeline equipment system, make the fluid more pure, and obtain ideal industrial products. After the basket filter is used for a period of time, the upper cover is opened and the basket-like filter screen is taken out. Once it is washed, it can be restored to as good as new.

[0003] In the prior art, when cleaning the filter screen, manual cleaning or cleaning equipment is generally used. Manual cleaning can generally only clean filter screens with relatively small weights, which is convenient for operators to hold the filter screen with one hand. However, it is more troublesome to clean filter screens with relatively large weights, and the manual cleaning efficiency is low. In the prior art, the cleaning method of the cleaning equipment is generally to place the filter screen inside the equipment and complete the cleaning of the filter screen by flushing with a high-pressure water gun. However, in the prior art, when most cleaning equipment cleans the filter screen, since the filter screen opening is inclined, the filter screen opening is upward for cleaning. Although this method can also wash off the impurities attached inside the filter screen, these impurities will accumulate inside the filter screen, and it often requires the operator to turn the filter screen for secondary cleaning to completely clean the filter screen, which increases the cleaning complexity.

A filter screen fixing table 4 is horizontally rotatably arranged at the bottom of the cleaning chamber 3. A vertical column 26 is vertically arranged on the upper side of the filter screen fixing table 4. A filter screen clamp 18 for fixing the filter screen upside down is sleeved and installed in the middle of the vertical column 26. A main water pipe 7 is vertically installed on the wall of the cleaning chamber 3. A water spray nozzle 9 is connected to the side of the main water pipe 7 through a connecting pipe 8. The water outlet end of the pneumatic water pump 2 is communicated with the main water pipe 7 through a water supply pipe 10.

[0028] Embodiment 2:

[0029] On the basis of the foregoing embodiment, as Figure 6 shown, an adjusting rod 5 is horizontally arranged on the wall of the cleaning chamber 3. A sliding seat 6 is slidably arranged on the adjusting rod 5 along its length direction. The sliding seat 6 is connected to the main water pipe 7. By providing the cooperation of the adjusting rod 5 and the sliding seat 6, the distance between the main water pipe 7 and the wall of the cleaning chamber 3 can be adjusted, so as to control the distance between the water spray nozzle 9 and the filter screen placed on the filter screen fixing table 4, and thus control the flushing distance according to the sizes of different specifications of filter screens, which can achieve a better cleaning effect. By providing a horizontally rotatable filter screen fixing table 4, during the process of cleaning the filter screen, the filter screen can be flushed all-round by means of the horizontal rotation of the filter screen fixing table 4, improving the flushing effect.

[0030] The adjusting rod 5 includes an inner rod 11 and an outer tube 12. One end of the inner rod 11 is connected to the wall of the cleaning chamber 3. The outer tube 12 is slidably sleeved on the outer wall of the inner rod 11. The sliding seat 6 is slidably sleeved on the outer wall of the outer tube 12 through a sliding sleeve 13. Such a setting can realize the distance adjustment by means of the mutual sliding between the inner rod 11, the outer tube 12 and the sliding sleeve 13. It can be adjusted by means of the elongation and shortening of the entire adjusting rod 5, and can also be adjusted by means of the sliding of the sliding sleeve 13 on the outer tube 12. Sealing rubber rings can be arranged on the inner wall of the outer tube 12 and the inner wall of the sliding sleeve 13. On the one hand, it can improve the stability of sliding, and at the same time, the friction force of sliding can be increased by means of the rubber rings, so that the position of the water spray nozzle 9 will not change easily during use after the distance is adjusted.

[0031] The connecting pipe 8 is a universal bellows pipe, and a plurality of universal bellows pipes and spray nozzles 9 are arranged along the length direction of the main water pipe 7. The orientation of the spray nozzle 9 can be adjusted through the universal bellows pipe. Adjusting the orientation of the spray nozzle 9 before cleaning according to different situations can improve the cleaning efficiency.

[0032] Embodiment 3:

[0033] On the basis of the foregoing embodiments, as Figures 3 - 5 shown, the filter clamp 18 includes a fixing ring 27 and a fixing rod 28. The fixing ring 27 is inclined and sleeved on the middle part of the column 26.

A fixing member 29 for fixing the edge of the filter opening is installed on the fixing rod 28; a plurality of fixing rods 28 and fixing members 29 are arranged in a matching manner around the outer wall of the column 26. With such a setting, when fixing the filter, the filter is placed with the mesh opening facing downwards and aligned with the column 26, and then the edge of the filter is fixed through the fixing member 29 on the fixing rod 28, and the fixing of the filter can be completed. Moreover, due to the gap between the fixing rods 28, the impurities washed down from the filter can be directly washed off and fall to the bottom of the cleaning chamber 3.

[0034] A sliding hole 30 penetrating both sides is provided on the side of the fixing member 29 facing the column 26. The fixing member 29 is slidably sleeved on the fixing rod 28 through the sliding hole 30. A threaded hole 31 communicating with the sliding hole 30 is provided on the upper side of the fixing member 29. A locking screw 32 is threadedly engaged in the threaded hole 31. The upper end of the locking screw 32 is connected with a knob plate 33 above the fixing member 29. A fixing piece 34 is provided on the side of the fixing member 29 facing the column 26. A fixing notch 35 is formed by the cooperation between the fixing piece 34 and the fixing rod 28. When fixing the edge of the filter, by pushing the fixing member 29 to slide on the fixing rod 28, the edge of the filter is placed in the fixing notch 35, and then by screwing the knob plate 33, the lower end of the locking screw 32 is brought into top contact with the surface of the fixing rod 28, so that the position between the fixing member 29 and the fixing rod 28 can be fixed, thereby fixing the edge of the filter. Moreover, filters of various specifications can be fixed in this way, improving the practicability of the entire device.

[0035] The lower side of the fixing piece 34 is inclined upwards towards the column 26 to form an inclined surface 36. Through the inclined surface 36, edges of various thicknesses can be adapted.

During the cleaning process, by starting the starting motor 20, the output shaft of the starting motor 20 drives the transmission rod 26 to rotate, and the transmission rod 26 drives the horizontal shaft of the right angle reducer 19 to rotate, thereby driving the vertical shaft of the right angle reducer 19 to rotate with the help of the gears inside the right angle reducer 19, so that the rotating shaft 17 and the rotating table 15 can be driven to rotate. After the cleaning is completed, the starting motor 20 is turned off to stop the rotation of the rotating table 15.

[0039] The mounting seat 14 is mounted in the cleaning chamber 3 through the horizontal mounting frame 21. A drain pipe 22 is provided in the middle of the bottom of the cleaning chamber 3, and the bottom of the cleaning chamber 3 is recessed toward the drain pipe 22 to form a funnel shape.
