DETAILED DESCRIPTION

[0024] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0025] See also Figures 1 to 4 The utility model provides an industrial gas filter with a replacement structure, including a filter body, the filter body including a detachably connected upper shell 1 and a lower shell 2, the upper shell 1 having a built-in filter element 3, the outer circumferential surface of the filter element 3 being provided with a rotating frame 4, the top of the filter element 3 being rotatably connected to the top of the upper shell 1, the lower portion of the rotating frame 4 being provided with a clamping groove 5, the bottom surface of the inner bottom surface of the clamping groove 5 being provided with a limit block 6, the inner side wall of the lower shell 2 being provided with a fixing element 7, the fixing element 7 being connected to a receiving portion, the top surface of the receiving portion being provided with a vertical rod 8, the top of the vertical rod 8 being connected with a clamping block 9, the clamping block 9 being located in the clamping groove 5, and being able to clamp with the limit block 6 when the clamping block 9 slides down in the clamping groove 5. Among them, a first flange 21 is provided at the bottom of the upper shell 1, and a second flange 22 is provided at the top of the lower shell 2. The first flange 21 and the second flange 22 are detachably connected by screws 23; a sealing strip 25 is provided at the bottom surface of the first flange 21 or the top surface of the second flange 22. A hanging part 24 is provided on the top surface of the upper shell 1 , and the hanging part 24 is a hanging ring or an annular iron chain.

[0026] It should be noted that the connection position of the first flange 21 and the second flange 22 is at 1\3 of the filter body, which is far away from the top of the upper shell 1. When the filter body is disassembled, the recoil mechanism that is not cleaned properly needs further manual deep cleaning. The hanger 24 facilitates the use of the filter body by hanging it off the ground while maintaining the stability and practicality of the filter. A sealing strip 25 is provided on the top surface of the second flange 22. When the first flange 21 and the second flange 22 are connected to generate an extrusion force, the sealing strip 25 expands to produce a sealing effect, preventing the filter body from leaking exhaust gas during operation, affecting the living environment and human health. The sealing strip 25 is made of silicone rubber.

[0027] Specifically, the screws 23 are removed between the first flange 21 and the second flange 22, so that when the upper shell 1 and the lower shell 2 are separated, the upper shell 1 is suspended at a fixed place by the hanger 24, and the lower shell 2, due to its own gravity, moves the vertical rod 8 and the clamping block 9 vertically downward in the clamping groove 5, so that the clamping block 9 is clamped with the limit block 6, and then the lower shell 2 is driven to rotate by an external force to separate the top of the rotating frame 4 from the top inside the upper shell 1, thereby separating the filter element 3 from the upper shell 1, avoiding direct contact of the hand with the filter element 3, and thus solving the technical problems in the prior art that the filter element 3 is easily rubbed and slipped when taken out by hand, and the pollutants attached to the outside of the filter element 3 are easy to damage the skin of the hand, increasing the risk of infection.

[0028] In addition, when reinstalling the filter element 3, the filter element 3 is fixed to the rotating frame 4, and the top of the filter element 3 and the rotating frame 4 are extended into the top of the upper shell 1 and slightly rotated to produce a slight fixing effect. By swinging the vertical rod 8, the clamping block 9 at its top is extended into the clamping groove 5. By utilizing the gravity of the lower shell 2, the clamping block 9 slides downward in the clamping groove 5, so that the clamping block 9 is clamped with the limit block 6. The lower shell 2 is rotated, and the clamping force of the clamping block 9 and the limit block 6 is utilized to deeply rotate the filter element 3 and the rotating frame 4 to make their connection more stable. Finally, the first flange 21 and the second flange 22 are fixedly connected using screws 23. The clamping block 9 moves upward in the clamping groove 5, so that the bottom surface of the rotating frame 4 can contact and be placed on the top surface of the receiving part, thereby further achieving a stabilizing effect.

[0029] It is worth mentioning that the clamping block 9 is limited in the upper and lower linear movement in the clamping groove 5, which is conducive to the upper shell 1 and the lower shell 2 sliding down linearly when separated, and completing the clamping with the limit block 6. At the same time, it cannot be separated from the clamping groove 5 when sliding up, providing a stable technical foundation for the next disassembly work.

[0030] Preferably, an air inlet 10 and an air outlet 11 are provided at the top of the upper shell 1. The air outlet 11 has an air filter channel 12 built in. The air filter channel 12 is at a right angle, one end of which is connected to the inner wall of the air outlet 11, and the other end is provided with a connecting ring 13, which is rotatably connected to the top of the filter element 3.

[0031] A threaded head is provided on the top of the filter element 3, and a threaded surface is provided on the connecting ring 13. When the rotating frame 4 extends into the outer shell and reaches the inner top, the threaded head and the threaded surface are tightly connected to prevent the unfiltered gas from passing through the connection and extending into the filter channel 12, affecting the cleanliness of the filtered gas.

[0032] It is worth noting that the threads at the top of the filter element 3 are coated with perfluorinated seal to improve the airtightness.

[0033] Preferably, the inner wall of the rotating frame 4 is detachably connected to the outer peripheral surface and bottom surface of the filter element 3 through rivets.

[0034] The rotating frame 4 and the filter element 3 are fixedly connected by rivets, which makes it more stable and convenient to rotate and disassemble the filter element 3.

[0035] Preferably, the receiving portion includes a bottom basin 14 , the bottom surface of the bottom basin 14 is provided with an elastic component, the top surface of the elastic component is provided with a receiving plate 15 , the receiving plate 15 is used to receive the filter element 3 sliding down; the left and right sides of the receiving plate 15 can slide along the inner wall of the bottom basin 14 .

[0036] When the top of the filter element 3 is separated from the top of the upper shell 1, due to its own gravity, it falls straight down to the upper surface of the receiving plate 15 under the limiting effect of the clamping groove 5 and the clamping block 9, and the elastic component cushions the impact, thus preventing a large amount of attachments from falling off and affecting the surrounding hygiene. Figure 2 As shown, the receiving plate 15 is trapezoidal in shape and fits the bottom basin 14 , so as to facilitate stable sliding on the inner wall of the bottom basin 14 .

[0037] Preferably, the elastic component includes a spring 16 and a secondary telescopic rod 17, the upper and lower ends of the secondary telescopic rod 17 are respectively connected to the receiving plate 15 and the bottom surface of the bottom basin 14, the inner wall of the top end of the spring 16 is fixed to the outer wall of the top surface of the secondary telescopic rod 17, and its bottom end is fixed to the bottom surface of the bottom basin 14.

[0038] When the receiving plate 15 slides downward to squeeze the spring 16 and the secondary telescopic rod 17, after the maximum squeezing is completed, the spring 16 rebounds, so that the receiving plate 15 returns to its original position. Among them, the secondary telescopic rod 17 is a telescopic rod conventionally sold on the market. When in use, the adapter spring 16 stabilizes the direction of the spring 16's elastic force and provides a stable buffering effect.

[0039] Preferably, the bottom end of the vertical rod 8 is connected to the top surface of the bottom basin 16 through a damping hinge element 18 .

[0040] The damping hinge element 18 is a damping hinge, which generates a certain resistance when the vertical rod 8 is swung. Without external force, the vertical rod 8 cannot swing, so that the vertical rod 8 does not affect its function of being fixed in the clamping groove 5 inside the upper shell 1.

[0041] Preferably, a sewage outlet 19 is provided at the bottom of the bottom shell, and a butterfly valve switch 20 is provided at the sewage outlet 19 .

[0042] The butterfly valve switch 20 can be opened to discharge the filtered pollutants after the filter body is finished working. It can also be opened when the upper shell 1 and the lower shell 2 are disassembled and separated to facilitate the staff to clean and discharge sewage.

[0043] Preferably, the fixing element 7 is a fixing block or a fixing ring.

[0044] The fixing ring is used to match the bottom basin 14 to improve the stability of the bottom basin 14. At the same time, the fixing block connected to the bottom basin 14 can also achieve stability. Specifically, appropriate accessories can be used according to actual conditions.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
