[0025] Please refer to the accompanying drawings Figures 1 to 4As shown, this utility model provides an industrial air conditioning dust filtration device, including a housing 10. A filter screen 11 is slidably connected inside the housing 10. A push rod 12 is slidably connected inside the filter screen 11. A first baffle 13 is fixed to the outer side of the push rod 12. A moving block 14 is slidably connected to the outer side of the push rod 12 and to one side of the first baffle 13. A fixing block 15 is fixed to one side of the push rod 12, and the fixing block 15 is located on the side of the moving block 14 away from the first baffle 13. A first spring 16 is provided between the moving block 14 and the fixing block 15. The filter screen 11 is slidably connected to the inner side of the housing 10 and to one side of the first baffle 13. A second baffle 17 is fixed to the lower end of the push rod 12. A moving rod 18 is slidably connected inside the second baffle 17. A snap-fit plate 19 is fixed to the upper end of the moving rod 18. A second spring 20 is provided at the upper end of the second baffle 17 and outside the moving rod 18. An inclined surface is provided on the side of the snap-fit plate 19 near the fixing block 15. A conical boss is provided on the side of the fixing block 15 near the snap-fit plate 19. A third baffle 21 is fixed inside the filter screen 11 and outside the push rod 12. A third spring 22 is provided on the side of the third baffle 21 near the first baffle 13.
[0026] In this embodiment, during installation, the filter screen 11 is pushed along the inside of the housing 10 to a certain position, where the conical protrusion of the fixing block 15 contacts the inclined surface of the snap-fit plate 19. Since the lower end of the snap-fit plate 19 is fixed with a moving rod 18, and the upper end of the second baffle 17 is provided with a second spring 20 located outside the moving rod 18, the second spring 20 is compressed when the conical protrusion of the fixing block 15 pushes the snap-fit plate 19 down. When the filter screen 11 stops moving, the second spring 20 resets, causing the snap-fit plate 19 to move up and snap into the fixing block 15, thus fixing the filter screen 11. At this time, the snap-fit plate 19 is located between the fixing block 15 and the moving block 14. When cleaning the filter screen 11, push the push rod 12. Because the first baffle 13 is fixed to the outside of the push rod 12, and a moving block 14 is slidably connected to the outside of the push rod 12 and on one side of the first baffle 13, the movement of the first baffle 13 causes the moving block 14 to compress the first spring 16. Continuing to push the push rod 12 causes the moving block 14 to push the snap-fit plate 19 down to compress the second spring 20. Because the fixed block 15 has a circular groove on the side near the moving block 14 that matches the moving block 14, when the moving block 14 and... When the fixed block 15 is located on the same side of the snap-fit plate 19, the push rod 12 is not pushed. The third spring 22 pushes the third baffle 21 to move under the action of the elastic force. At this time, the moving block 14 slides into the circular groove opened in the fixed block 15. Since the moving block 14 has inclined surfaces on both sides, when the moving block 14 and the fixed block 15 move, they push the snap-fit plate 19 to move down and compress the second spring 20. When the moving block 14 and the fixed block 15 move to the other side of the snap-fit plate 19, the filter screen 11 can be pulled out.
[0027] In the initial state, the first spring 16 is in its natural state, the moving block 14 and the fixed block 15 maintain a certain distance, the third baffle 21 is located at the rightmost end under the action of the third spring 22, and the filter screen 11 and the outer shell 10 are both provided with circular through holes of the same size, and the two circular through holes are located on the same horizontal plane.
[0028] Secondly, please refer to the following as well. Figure 3 and Figure 4 Multiple rollers 23 are rotatably connected to both the upper and lower ends of the filter screen 11, and the multiple rollers 23 are linearly and uniformly distributed in the horizontal extension direction of the filter screen 11.
[0029] In this embodiment, during the process of inserting or removing the filter screen 11 into the housing 10, the roller 23 contacts and rolls against the inner wall of the housing 10, which can transform the sliding friction between the filter screen 11 and the housing 10 into rolling friction. This greatly reduces the friction force experienced by the filter screen 11 during installation and removal, making the installation and removal of the filter screen 11 easier and smoother, reducing the labor intensity of operators and improving work efficiency.
[0030] To further understand and explain, Figure 2 For example, two fixing rods 24 are fixed on one side of the filter screen 11, and a handle 25 is slidably connected between the two fixing rods 24. The outer side of the handle 25 is provided with anti-slip texture.
[0031] In this embodiment, the handle 25 provides an easy gripping point for the operator. When it is necessary to install, remove or move the filter 11, the operator can directly hold the handle 25, which is more labor-saving and easier to apply force compared to directly gripping the filter 11, and can complete the relevant operations more easily.
[0032] In a preferred embodiment, please refer to Figure 3 A sealing ring is provided between the filter screen 11 and the outer shell 10, and the sealing ring is made of rubber.
[0033] In this embodiment, sealing rings (not shown in the figure) are provided at both ends of the outer side of the filter screen 11, and the sealing rings are located between the filter screen 11 and the outer shell 10. The sealing rings ensure the sealing between the filter screen 11 and the outer shell 10 and prevent gas from leaking from the gap between the filter screen 11 and the outer shell 10.
[0034] The working principle of this utility is as follows:
[0035] When installing the filter screen 11, push it to move it inside the outer casing 10. The conical protrusion of the fixing block 15 contacts the inclined surface of the snap-fit plate 19, pushing the snap-fit plate 19 downward to compress the second spring 20. After the filter screen 11 is in place, the second spring 20 returns to its original position, and the snap-fit plate 19 moves upward to snap into the fixing block 15 for fixation. When removing the filter screen 11, push the push rod 12. The first baffle 13 drives the moving block 14 to move. The movement of the moving block 14 causes the snap-fit plate 19 to move downward. When the moving block 14 and the fixing block 15 are on the same side of the snap-fit plate 19, do not push the push rod 12. At this time, the third spring 22 pushes the third baffle 21, causing the moving block 14 to slide into the groove of the fixing block 15. Under the action of the third spring 22, the moving block 14 and the fixing block 15 are on the other side of the snap-fit plate 19, and the filter screen 11 can be pulled out. During the installation and removal of the filter screen 11, the upper and lower rollers 23 convert sliding friction into rolling friction, reducing friction and facilitating operation. The rubber sealing ring between the filter screen 11 and the outer casing 10 ensures airtightness and prevents gas leakage.
[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
