Description

Technical Field

[0001] This utility model belongs to the technical field of chemical fiber equipment and relates to a compressed air filter element cleaning device. Background Technology

[0002] Compressed air filters require regular maintenance and replacement of the filter element. The surface of the removed filter element is covered with metal shavings and other impurities, and it must be cleaned before it can be used again.

[0003] CN201810097605.5 describes a device that uses a compression spring to clamp a filter element, a motor and gears to rotate a filter element clamping platform, and another motor and pulley to move a sliding side rod to move a cleaning head up and down. A water pump then draws water from a nozzle to rinse the filter element surface, achieving full-surface cleaning. However, using water to clean the exterior of a compressed air filter element can easily push impurities from one end of the filter holes into the depths of the filter holes, resulting in incomplete cleaning. Furthermore, relying on a motor to rotate the filter element clamping platform presents energy consumption issues.

[0004] Therefore, it is of great significance to study a compressed air filter cleaning device to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art and provide a compressed air filter element cleaning device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A compressed air filter cleaning device includes a cleaning pipe, two end caps, and two bearings;

[0008] The cleaning tube is inserted into the compressed air filter element to guide the fluid to impact the inner wall of the compressed air filter element, causing the compressed air filter element to rotate around its own central axis.

[0009] Two end caps are used to clamp the compressed air filter element;

[0010] The two ends of the cleaning tube pass through two end caps respectively, and the way they pass through is such that when the end caps rotate, the cleaning tube does not rotate with them;

[0011] Two bearings are respectively embedded in two end caps, and the outer rings of the two bearings are respectively interference-fitted with the two end caps;

[0012] The cleaning tube passes through the end cap and also through the bearing embedded in the end cap, with the cleaning tube having an interference fit with the inner ring of the bearing;

[0013] The specific usage process is as follows: First, install the compressed air filter element on the compressed air filter element cleaning device, then adjust the water pressure to guide the fluid to impact the inner wall of the compressed air filter element, so that the compressed air filter element rotates around its own central axis, thereby avoiding the problem of existing technology requiring a motor to drive the compressed air filter element to rotate, which wastes energy;

[0014] The compressed air filter element includes a hollow cylindrical body with multiple filter holes evenly distributed on its circumference. The end of the filter hole on the outer wall of the compressed air filter element is port A, and the end on the inner wall is port B. In existing compressed air filter elements, although impurities are in the filter holes, they are closer to port A, denoted as point C. In existing technology, water is rinsed from the outside of the compressed air filter element. To flush out impurities, they need to move from point C to port B, a long distance that is difficult to remove. The design of this application, which cleans from the inside of the compressed air filter element, requires impurities to move only from point C to port A, a shorter distance, making them easier to flush out.

[0015] As a preferred technical solution:

[0016] The compressed air filter cleaning device described above has a cleaning pipe consisting of one straight pipe a, n straight pipes b and n straight pipes c, where n>1;

[0017] One end of straight pipe a is open, and the other end is closed;

[0018] n straight pipes b are arranged at intervals along the length of straight pipe a and are simultaneously connected to straight pipe a. The central axis of straight pipe b is perpendicular to the central axis of straight pipe a, and the central axes of the n straight pipes b are parallel to each other.

[0019] n straight pipes c are connected to n straight pipes b respectively to form n L-shaped pipes. The central axis of straight pipe c is perpendicular to the central axis of straight pipe a, and the central axes of the n straight pipes c are parallel to each other.

[0020] The two ends of the cleaning tube passing through the two end caps respectively means that the two ends of the straight tube a pass through the two end caps respectively. The interference fit between the cleaning tube and the inner ring of the bearing means that the straight tube a and the inner ring of the bearing are interference fit.

[0021] The L-shaped tube design ensures that the horizontal component of the force exerted by water on the inner wall of the compressed air filter element is not perpendicular to the inner wall of the compressed air filter element, allowing the water to drive the compressed air filter element to rotate.

[0022] As described above, in a compressed air filter cleaning device, the straight pipe a consists of two length sections connected by threads.

[0023] The compressed air filter cleaning device described above further includes two annular retaining rings; two annular retaining ring grooves are provided on the circumferential surface of the straight pipe a; one retaining ring is fitted on one annular retaining ring groove and is tightly attached to the inner ring of one bearing; the other retaining ring is fitted on the other annular retaining ring groove and is tightly attached to the inner ring of another bearing;

[0024] When the two length segments are inserted and threaded into the two ports of the compressed air filter element, the two end caps are each tightly fitted to one port of the compressed air filter element. If it is necessary to increase the tightness to improve the seal between the end caps and the compressed air filter element, the two length segments need to be screwed on separately to increase the length of the connection between the external thread segment and the internal thread segment. At this time, the compressed air filter element will exert a reverse force on the end caps. Although the end caps and the cleaning tube are interference-fitted, the design of the retaining ring and the annular retaining ring groove can play a double insurance role in order to prevent accidents and avoid the movement of the cleaning tube.

[0025] As described above, the compressed air filter cleaning device has two wrench grooves on the straight pipe a. The two wrench grooves are located near the two ends of the straight pipe a. The wrench grooves are used to cooperate with the wrench to make the threaded connection of the two length sections easier.

[0026] As described above, the compressed air filter cleaning device has grooves on the clamping surfaces of the two end caps, and sealing gaskets are embedded in the grooves. The sealing gaskets are used to seal the connection when the end caps clamp the compressed air filter.

[0027] The compressed air filter cleaning device described above further includes two elastic sealing rings; the two elastic sealing rings are respectively embedded in two end caps; when the cleaning pipe passes through the end caps, it also passes through the elastic sealing rings embedded in the end caps; the cleaning pipe and the elastic sealing rings are interference-fitted.

[0028] The design of the sealing gasket and elastic sealing ring ensures that the output water only flows out of the compressed air filter element through the filter holes, thus better removing impurities.

[0029] The compressed air filter cleaning device described above also includes a housing, a water supply pipe, a connecting pipe, and a housing cover;

[0030] The lid is used to close the box.

[0031] The box is equipped with a cleaning tank;

[0032] The cleaning tank has two notches on its wall, which are used to support the two length sections of the cleaning pipe located outside the two end caps.

[0033] The dimensions of the cleaning tank meet the following requirements: after the two end caps clamp the compressed air filter element, it can form a stable suspended state in the cleaning tank with the support of the cleaning pipe.

[0034] The water supply pipe is a hollow pipe with one end closed; the water supply pipe is detachably fixed inside the box, and the open end of the water supply pipe protrudes outside the box; a through hole a is provided on the circumference of the water supply pipe, and one end of the connecting pipe is connected to the through hole a; the other end of the connecting pipe is used to connect to the open end of the straight pipe a.

[0035] The compressed air filter cleaning device described above also includes a drain pipe; the drain pipe connects the external space of the housing and the cleaning tank.

[0036] Beneficial effects:

[0037] This utility model discloses a compressed air filter cleaning device that backwashes from the inside, guiding fluid to impact the inner wall of the compressed air filter, causing the compressed air filter to rotate around its own central axis, thus avoiding energy waste and effectively removing particulate impurities from the pores.
