DETAILED DESCRIPTION

[0026] In order to make the purpose and the advantage of the utility model more clearly, the following is combined with embodiment to carry out the specific description of the utility model. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope of the utility model specifically requested.

[0027] As Figures 1 to 6 Indicated, a filter convenient for replacing filter element, including filter box 10, the inside of filter box 10 is set up installation groove 11, installation groove 11 is divided into first filter groove 111 and second filter groove 112, the lower portion of installation groove 11 is set up air inlet 12, and the upper portion of installation groove 11 is set up filter outlet 13;

[0028] Adjusting mechanism 20, adjusting mechanism 20 includes drive motor 21, drive motor 21 is fixed in the inside of filter box 10, and the output end of drive motor 21 is fixedly connected with one end of adjusting rod 22, the other end of adjusting rod 22 is rotatably connected with the inner wall of filter box 10, and the outer side of adjusting rod 22 is fixed with adjusting plate 23, adjusting plate 23 is slidably connected with the inner wall of air inlet 12;

[0029] The taking and placing mechanism 30 comprises a plurality of taking and placing plates 31 which are respectively slidably connected with the first filter groove 111 and the second filter groove 112, and each of the taking and placing plates 31 is internally provided with a fixing groove, and each of the taking and placing plates 31 located at one end inside the filter box 10 is fixedly provided with a positioning pin column;

[0030] In the embodiment, it should be noted that the controller (not shown in the figure) is arranged when cooperating with the filter, and the controller is electrically connected with the driving motor 21, so that the rotation of the driving motor 21 can be accurately controlled (this is a conventional technology, and will not be described in detail here), so that the driving motor 21 effectively drives the adjusting plate 23 to be slidably connected with the inner wall of the air inlet 12. When the driving motor 21 is started, the adjusting rod 22 and the adjusting plate 23 are driven, so that the outer side of the adjusting plate 23 is slidably connected with the inner wall of the air inlet 12. When the adjusting plate 23 is rotated to a specified position, the outer side of the adjusting plate 23 is matched with the inner wall of the air inlet 12, so that the air inlet 12 cannot supply air to the filter groove above. At this time, the taking and placing plate 31 in the filter groove is taken and placed, so that the taking and placing plate 31 effectively drives the filter element to be replaced. When the filter element replacement of the filter groove is completed, the driving motor 21 can be started again to drive the adjusting plate 23 to be slidably connected with the air inlet 12 at the bottom of the other filter groove, so as to close the other filter groove and complete the replacement of the filter element. The filter box 10 can complete the replacement of the filter element without interrupting the filtering process, thereby improving the operation efficiency of the equipment.

[0031] As shown in Figure 2 , Figure 3 , the air inlet 12 is provided with a guide groove 121 on the front and rear sides inside the filter box 10, and the upper side of the air inlet 12 is in communication with the lower side of the mounting groove 11, and the upper side of the mounting groove 11 is in communication with the lower side of the filter outlet 13. By connecting the air inlet 12 with the mounting groove 11, the gas can be effectively filtered by the filter element to remove impurities and particulate pollutants in the gas. At the same time, the mounting groove 11 is in communication with the filter outlet 13, so that the filtered gas can be effectively output.

[0032] Preferably, the two ends of the adjusting plate 23 away from the adjusting rod 22 are respectively fixedly provided with sliding pin columns 231, and the sliding pin columns 231 are respectively slidably connected with the guide grooves 121.

[0033] In this embodiment, it should be noted that the outer side of the adjusting plate 23 is made of rubber material and has a certain elasticity, and when sliding with the inner wall of the air inlet 12, it can ensure the sealing with the inner wall of the air inlet 12 when reaching the closed position. The sliding pin 231 is fixed on both sides of the adjusting plate 23 and is in sliding connection with the guide groove 121 on both sides of the inside of the air inlet 12. When the driving motor 21 works, the adjusting plate 23 and the sliding pin 231 are effectively driven to move in the guide groove 121 by the adjusting rod 22, which ensures the stability and accuracy of the adjusting process of the adjusting plate 23.

[0034] As shown in Figure 3 , Figure 5 , Figure 6 The two sides of the taking and placing plate 31 near one end of the positioning pin are respectively provided with sliding grooves 311, the sliding grooves 311 are in sliding connection with sliding blocks 312, and the sliding blocks 312 and the sliding grooves 311 are assembled with return springs. It should be noted that the sliding block 312 is a trapezoidal protrusion, and the two sides of the sliding block 312 that do not slide with the sliding groove 311 are trapezoidal inclined surfaces. The return springs are respectively fixedly connected with the sliding blocks 312 and the sliding grooves 311, and the end of the sliding groove 311 away from the return spring is provided with an inclined groove matched with the trapezoidal inclined surface.

[0035] Preferably, the sliding groove 311 is in sliding connection with a limiting rod 32, the limiting rod 32 is in sliding connection with the inside of the filter box 10, and the limiting rod 32 and the filter box 10 are assembled with a limiting spring. The limiting spring is respectively fixedly connected with the limiting rod 32 and the inside of the filter box 10.

[0036] In a preferred embodiment, it should be noted that the end of the taking and placing plate 31 away from the outlet is made of rubber material and has a certain elasticity, and the two sides of the taking and placing plate 31 in contact with the limiting rod 32 are inclined surfaces. When the taking and placing plate 31 slides with the mounting groove 11, since the limiting rod 32 is slidingly arranged in the inside of the filter box 10, when the taking and placing plate 31 contacts the limiting rod 32, the limiting rod 32 is extruded by the inclined surface, so that the limiting rod 32 shrinks. When the taking and placing plate 31 moves to the specified position, at this time, the limiting rod 32 is located outside the sliding groove 311, and since the limiting rod 32 is not extruded by external force, the limiting rod 32 is driven to slide into the sliding groove 311 by the action of the limiting spring and contacts one side of the sliding groove 311 away from the sliding block 312. At this time, the limiting rod 32 cooperates with the sliding groove 311 to limit the taking and placing plate 31, thereby ensuring the stability of the filter core in use.

[0037] Preferably, the positioning pin is in sliding connection with the inside of the filter box 10, and the outside of the positioning pin is assembled with an elastic member, and the elastic member is fixedly connected with the taking and placing plate 31.

[0038] Based on the previous embodiment, in this embodiment, it needs to be pointed out that the elastic force of the elastic member is greater than the elastic force of the limiting spring, which is greater than the elastic force of the reset spring. When the taking and placing plate 31 is taken, the taking and placing plate 31 is pressed again, so that the taking and placing plate 31 moves again to the inside of the filter box 10, at this time, the sliding groove 311 drives the internal sliding block 312 to move, when the sliding block 312 contacts the limiting rod 32, the limiting rod 32 will shrink through the inclined surface of the sliding block 312 and move to the outside of the sliding block 312, when it moves to the other inclined surface of the sliding block 312, at this time, because the elastic force of the limiting spring is greater than the elastic force of the reset spring, the limiting spring drives the limiting rod 32 and slides along the other inclined surface of the sliding block 312 into the sliding groove 311. At this time, no pressure is applied to the taking and placing plate 31, and the taking and placing plate 31 will rebound through the elastic force of the elastic member, at the same time, the limiting rod 32 drives the sliding block 312 to slide in the sliding groove 311, so that the inclined surface of the sliding groove 311 away from the reset spring side contacts the inclined groove in the sliding groove 311. Because the elastic force of the elastic member is greater than the elastic force of the limiting spring, when the sliding block 312 cannot move due to resistance, the limiting rod 32 will be extruded through the other inclined surface, so that the limiting rod 32 shrinks and moves to the surface of the sliding block 312, at this time, the sliding block 312 is matched with the sliding groove 311, and the limiting rod 32 moves along the surface of the sliding block 312 to the surface of the taking and placing plate 31, without limiting the taking and placing plate 31, so that the taking and placing plate 31 can be taken out.

[0039] The working principle of the utility model is as follows: when the filter element needs to be replaced, the drive motor 21 is controlled to drive the adjusting rod 22 and the adjusting plate 23 to slide in the air inlet 12, when sliding to the two ends of the guide groove 121, the first filter groove 111 and the second filter groove 112 above the air inlet 12 can be closed respectively, so that air cannot enter the filter grooves. At this time, the taking and placing plate 31 in the filter groove can be pressed to move and extrude the limiting rod 32, through the cooperation of the limiting rod 32 and the sliding block 312, the limiting of the taking and placing plate 31 is released, so that the taking and placing plate 31 can be quickly taken out, and the filter element in the taking and placing plate 31 can be replaced. After the replacement of the filter element is completed, the taking and placing plate 31 is placed in the filter groove, the sliding groove 311 in the taking and placing plate 31 is matched with the limiting rod 32 by pushing the taking and placing plate 31, so as to limit the taking and placing plate 31, ensuring the stability of the taking and placing plate 31 in use. By replacing the filter elements in the filter grooves in turn, the filter box 10 can replace the filter elements without stopping the filtering work, improving the operating efficiency of the filter.

[0040] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as falling within the scope of protection of the present application. Structures, devices and operation methods not specifically described and explained in the present application are implemented according to conventional means in the art, unless otherwise specified and limited.
