[0002] Filter element is a professional term for filtering and purification functions. In order to purify the resources of the original fluid and the simple device for separating the resources, the filter element is now mainly used in the filtration industry such as oil filtration, air filtration, and water filtration. The filter element can separate solid particles in liquid or gas, or make different material components fully contact and speed up the reaction time. When the fluid enters the filter element with a filter screen of a certain specification, its impurities are blocked, and the clean fluid flows out through the filter element, which can protect the normal operation of the equipment or the cleanliness of the air.

[0003] After long-term use, the filter element will usually have a lot of impurities attached to the filter screen, causing the filter holes to be blocked and affecting the operation of the equipment. Therefore, the filter element needs to be disassembled and cleaned. When using existing filter elements, it usually requires operators with professional skills to disassemble them, and complex tools are required, which is not convenient for daily maintenance. In addition, since the filter element body cannot be separated, the cleaning between the multi-layer filter screens is not thorough, affecting the filtering performance of the filter element. In view of this, the present application proposes a filter element that is easy to disassemble and clean. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 and Figure 4 As shown, in the present embodiment, a filter element which is easy to disassemble and clean comprises a base 1, an annular groove is provided on the upper surface of the base 1, an inner cylinder 2 and an outer cylinder 3 are respectively arranged in the annular groove, two threaded sleeves 5 are fixedly installed on the side wall of the base 1, first threaded rods 6 are respectively penetrated through the two threaded sleeves 5, one end of the two first threaded rods 6 is respectively fixedly connected with a first knob 7, and the other ends of the two first threaded rods 6 are respectively rotatably connected with a clamping plate 8, two second threaded rods 12 are respectively provided at the top of the inner cylinder 2 and the outer cylinder 3 through a connecting mechanism, the tops of the two second threaded rods 12 are respectively fixedly connected with a second knob 13, and the bottoms of the two second threaded rods 12 are respectively fixedly connected with abutment blocks 14, and two brackets 15 are symmetrically installed on the side wall of the outer cylinder 3, the two brackets 15 are respectively connected with movable rods 17 through connecting rods 16, and the bottoms of the two movable rods 17 are respectively fixedly connected with extension plates 18.

[0022] An annular fixing plate 4 is provided on the outer wall of the inner tube 2 , and one end of the fixing plate 4 contacts the inner wall of the outer tube 3 . The position of the fixing plate 4 corresponds to the position of the clamping plate 8 .

[0023] The fixing plate 4 is arranged to abut against the inner wall of the outer tube 3. When the outer tube 3 is clamped by the clamping plates 8 on both sides, the fixing plate 4 can play a supporting role to prevent the outer tube 3 from being deformed, and transmit the force applied by the clamping plates 8 to the inner tube 2, so that the inner tube 2 and the outer tube 3 form a whole and are fixed at the same time.

[0024] Among them, sliding grooves are symmetrically opened on both sides of the annular groove on the base 1, and two clamping plates 8 are respectively arranged in the corresponding sliding grooves, and the diameters of the two arc-shaped clamping plates 8 correspond to the diameter of the outer cylinder 3.

[0025] The inner wall of the sliding groove is in contact with the side wall of the clamping plate 8, which can limit the clamping plate 8 and make the clamping plate 8 move smoothly, and finally maintain a sufficient contact surface with the outer tube 3, thereby improving the stability of clamping.

[0026] Among them, the connection mechanism includes a top plate 10 and a splicing plate 11. The top plate 10 is fixedly set on the outer tube 3, and the splicing plate 11 is fixedly set on the inner tube 2. Both the top plate 10 and the splicing plate 11 are provided with threaded holes, and the second threaded rod 12 is penetrated and set in the corresponding threaded holes.

[0027] By screwing the second threaded rod 12 into the threaded holes provided on the top plate 10 and the splicing plate 11, the tops of the inner cylinder 2 and the outer cylinder 3 can be connected so that the inner cylinder 2 and the outer cylinder 3 are fixed as a whole.

[0028] The bracket 15 is composed of two vertical plates, the connecting rod 16 is arranged between the two vertical plates, the connecting rod 16 is fixedly connected to the side walls of the two vertical plates, and the connecting rod 16 passes through the movable rod 17 and is rotatably connected to the movable rod 17 .

[0029] By sleeve-arranging the movable rod 17 on the connecting rod 16 , the movable rod 17 can be rotated relative to the bracket 15 under the connection of the connecting rod 16 .

[0030] The movable rod 17 is designed to be L-shaped, one end of the movable rod 17 passes through the outer tube 3 and extends to below the second threaded rod 12 , and the side wall of the movable rod 17 is in contact with the abutment block 14 .

[0031] By applying pressure to one end of the movable rod 17 through the abutment block 14 , the movable rod 17 can be rotated around the connecting rod 16 as the axis, thereby adjusting the position of the extension plate 18 .

[0032] A backing plate 9 is fixedly mounted on the outer wall of the outer cylinder 3 , and the position of the backing plate 9 corresponds to the position of the extension plate 18 .

[0033] By adding the pad 9 to the outer cylinder 3 , the extension plate 18 will contact the pad 9 when it is retracted, thereby preventing the extension plate 18 from colliding with the surface of the outer cylinder 3 and causing damage.

[0034] The utility model provides a filter element that is easy to disassemble and clean. The specific working principle is as follows: the second knob 13 is turned to drive the second threaded rods 12 on both sides to rotate, and under the limit of the threaded holes on the top plate 10 and the splicing plate 11, the second threaded rod 12 is moved, driving the abutment block 14 at the bottom of the second threaded rod 12 to separate from the movable rod 17, and the movable rods 17 on both sides are rotated with the corresponding connecting rod 16 as the axis, driving the extension plate 18 to retract, so that the extension plates 18 on both sides are out of contact with the external pipe, so that the filter element can be taken out as a whole, and then separated. Don't turn the first knob 7 to drive the first threaded rod 6 on both sides of the road to rotate. Under the fixation of the threaded sleeve 5, the first threaded rod 6 will move with the first clamping plate 8 to separate the side walls of the clamping plates 8 on both sides from the outer cylinder 3. The outer cylinder 3 and the inner cylinder 2 are no longer fixed by clamping. At this time, the outer cylinder 3 and the inner cylinder 2 can be moved out of the annular groove on the base 1, and the second knob 13 is turned again to finally separate the second threaded rod 12 from the splicing plate 11 and the top plate 10, so that the inner cylinder 2 and the outer cylinder 3 can be taken out respectively, which is convenient for cleaning different positions of the filter element.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
