Description

Technical Field

[0001] This utility model relates to the field of air filter manufacturing technology, specifically a detachable and modular air filter. Background Technology

[0002] Air filters are devices that use porous filter materials to capture dust from a gas-solid two-phase flow and purify the gas. However, long-term use can lead to filter screen blockage, which can affect the normal operation of the filter.

[0003] According to a detachable, modular air filter (publication number: CN222871623U), when the protective frame is installed, the sliding protective frame abuts against the inclined sides of the second trapezoidal blocks on both sides, pushing the second trapezoidal blocks towards the filter body. The inwardly sliding second trapezoidal blocks abut against the inclined sides of the first trapezoidal block, thereby pushing the first trapezoidal block and fixing the rubber fixing blocks on both sides to fix the filter plate.

[0004] However, in actual use, when the filter screen needs to be replaced multiple times, the extensive disassembly process causes dust on the filter screen to enter the interior of the filter, affecting its use. In view of this, we propose a detachable and modular air filter. Utility Model Content

[0005] The purpose of this invention is to provide a detachable, modular air filter to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable, modular air filter, comprising a housing, a frame provided on the side wall of the housing, a filter screen plate detachably connected to the inner wall of the frame by screws, a protective mechanism provided on the outer side of the housing, and an auxiliary mechanism provided on the outer side of the housing, the protective mechanism comprising: Mounting block, the mounting block is fixedly installed on the upper surface of the box, the upper surface of the frame is fixedly installed with a connecting block, and the mounting block is provided with bolts inside; The mounting bracket is fixedly installed on the lower surface of the housing. A straight rod is fixedly installed on the inner wall of the mounting bracket, and a curved plate is rotatably connected to the arc surface of the straight rod.

[0007] Preferably, the auxiliary mechanism includes a limiting arc block, which is fixedly installed on the lower surface of the frame, and a rubber block is fixedly installed on the lower surface of the box.

[0008] Preferably, the limiting arc block rotates with the frame to a near-horizontal position, and the limiting arc block can contact the rubber block. This allows the frame to rotate only a certain angle, while simultaneously supporting the frame at a certain tilt angle, facilitating the replacement of the filter screen.

[0009] Preferably, the end of the bent plate away from the mounting bracket is fixedly installed on the lower surface of the frame, and the bent plate is located outside the limiting arc block, so that the rotation of the frame drives the bent plate to rotate.

[0010] Preferably, the bolt passes through the mounting block and the mating block and is fixed by a nut, and the mating block is located inside the mounting block, so that the bolt, together with the mounting block and the mating block, fixes the frame.

[0011] Preferably, there are two mounting brackets, which are arranged in a mirror image on the lower surface of the housing. The arrangement of the two mounting brackets ensures that the frame can rotate stably.

[0012] Preferably, the surface of the bent plate is provided with a circular hole, and the bent plate is in the shape of a hook, so that the bent plate can stably drive the frame to rotate.

[0013] Compared with the prior art, this utility model provides a detachable and modular air filter, which has the following advantages:

[0014] 1. This detachable, modular air filter features a protective mechanism. By releasing the bolts, the connecting block and the mounting block can be separated, allowing the frame to rotate on the straight rod in conjunction with the curved plate and move to the appropriate position. This moves the filter screen away from the interior of the housing, enabling the filter screen to be removed and replaced. This modular disassembly reduces the possibility of impurities entering the housing due to vibration of the filter screen during disassembly.

[0015] 2. This detachable, modular air filter is equipped with an auxiliary mechanism and a limiting arc block. This allows the frame and the curved plate to rotate along the straight rod to a suitable position, so that the limiting arc block can contact the rubber block to limit the angle of the frame. At the same time, the rubber pad reduces the impact of the limiting arc block, which could cause impurities on the frame to scatter, thereby reducing the possibility of impurities entering the housing.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a detachable splicing air filter, including a housing 1, a frame 2 provided on the side wall of the housing 1, a filter screen 5 detachably connected to the inner wall of the frame 2 by screws, a protective mechanism 3 provided on the outer side of the housing 1, and an auxiliary mechanism 4 provided on the outer side of the housing 1. The protective mechanism 3 includes a mounting block 301, a docking block 302, a bolt 303, a mounting bracket 304, a straight rod 305, and a curved plate 306.

[0022] In one embodiment of this utility model, the mounting block 301 is fixedly mounted on the upper surface of the box 1, the connecting block 302 is fixedly mounted on the upper surface of the frame 2, the mounting block 301 is provided with bolts 303 inside, the mounting bracket 304 is fixedly mounted on the lower surface of the box 1, the inner wall of the mounting bracket 304 is fixedly mounted with a straight rod 305, and the arc surface of the straight rod 305 is rotatably connected to a bent plate 306.

[0023] In addition, the auxiliary mechanism 4 includes a limiting arc block 401, which is fixedly installed on the lower surface of the frame 2, and a rubber block 402 is fixedly installed on the lower surface of the housing 1. The limiting arc block 401 rotates with the frame 2 to a near-horizontal position, and the limiting arc block 401 can contact the rubber block 402, thereby allowing the frame 2 to rotate only at a certain angle, while supporting the frame 2 to tilt at a certain angle, facilitating the replacement of the filter screen 5.

[0024] In this embodiment of the invention, the end of the bent plate 306 furthest from the mounting bracket 304 is fixedly mounted on the lower surface of the frame 2, and the bent plate 306 is located outside the limiting arc block 401. The rotation of the frame 2 then drives the bent plate 306 to rotate. Bolts 303 pass through the mounting block 301 and the mating block 302 and are fixed by nuts. The bent plate 306 is located outside the limiting arc block 401, and the bolts 303, in conjunction with the mounting block 301 and the mating block 302, fix the frame 2. Two mounting brackets 304 are provided, mirror-distributed on the lower surface of the housing 1. The arrangement of the two mounting brackets 304 ensures stable rotation of the frame 2. The surface of the bent plate 306 has a circular hole, and the bent plate 306 is hook-shaped, allowing the bent plate 306 to stably drive the frame 2 to rotate.

[0025] In this utility model, during use, the connecting block 302 and the mounting block 301 are separated by releasing the bolt 303, so that the frame 2 can rotate on the straight rod 305 in conjunction with the bent plate 306 and move to a suitable position, thereby moving the filter screen 5 away from the inside of the housing 1. Then the filter screen 5 can be removed and replaced, thus completing the splicing disassembly and reducing the possibility of impurities entering the inside of the housing 1 due to the vibration of the filter screen 5 during the disassembly process.

[0026] Furthermore, a limiting arc block 401 is provided so that the frame 2, in conjunction with the curved plate 306, rotates along the straight rod 305 to a suitable position, allowing the limiting arc block 401 to contact the rubber block 402 and thus limit the angle of the frame 2. At the same time, the setting of the rubber block 402 reduces the collision of the limiting arc block 401, which would cause impurities on the frame 2 to scatter, thereby reducing the possibility of impurities entering the interior of the box 1.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
