Description

Technical Field

[0001] This utility model relates to the field of exhaust gas filter technology, and specifically to an exhaust gas filter that is easy to connect and install. Background Technology

[0002] EPE (Expanded Polyethylene) foam is a new type of environmentally friendly packaging material, mainly made from low-density polyethylene resin through a physical foaming process. EPE foam has a closed-cell structure and is produced by extrusion molding into sheets through the addition of foaming agents and anti-shrinkage agents. During the production of EPE foam, exhaust gas filters are used to treat the generated waste gas. Exhaust gas filters are devices that remove particulate matter, harmful gases, and odors from waste gas using physical or chemical methods, thereby reducing environmental pollution and protecting human health.

[0003] Chinese utility model patent CN222151354U discloses an easy-to-connect exhaust gas filtration device, which includes "using a folded corrugated pipe to adjust the position of the rubber connecting pipe, using the gaps opened inside the rubber connecting pipe to change the size of the connecting end of the rubber connecting pipe, and using elastic cable ties and fixing devices to tighten the rubber connecting pipe and the exhaust gas output pipe"; however, the method of connecting the air inlet pipe and the connecting pipe only by elastic cable ties is prone to damage from external influences during actual use, resulting in internal gas leakage, which in turn affects the filtration effect of the exhaust gas filter. Utility Model Content

[0004] The purpose of this invention is to provide an exhaust gas filter that is easy to install, in order to solve the problem mentioned in the background art that the method of connecting the air inlet pipe and the connecting pipe by means of elastic cable ties is easily affected by external factors during actual use, causing the cable ties to break and resulting in internal gas leakage, which in turn affects the filtration effect of the exhaust gas filter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an exhaust gas filter that is easy to install, including a centrifugal exhaust fan, one end of which is connected to a filter chamber, the other end of which is connected to an air inlet pipe, the other end of which is equipped with a connecting pipe, and a docking clip is installed on the outside of the connecting pipe.

[0006] One end of the air intake pipe is fixedly connected to a first flange. The inner wall of the first flange is embedded with a limiting groove, the outer wall of the first flange is embedded with a first retaining groove, and the inner wall of the first flange is embedded with a first threaded groove.

[0007] One end of the connecting pipe is fixedly connected to a second flange. A limiting protrusion is fixedly connected to the inner wall of the second flange. A second groove is embedded in the outer wall of the second flange. A second threaded groove is embedded in the inner wall of the second flange. A locking screw is installed on the inner wall of the limiting protrusion. A locking nut is threaded onto the outer side of the locking screw.

[0008] The beneficial effects of this utility model are as follows: by setting two flanges at the joint of the air inlet pipe and the connecting pipe and connecting them with externally set docking blocks to further fix them together, it is convenient to connect the two pipes and improve the connection effect between the pipes. It also prevents the joint from being damaged by external influences and causing internal gas leakage. In conjunction with the double filter plates of the filter chamber, it adsorbs and filters particulate matter and harmful gases in the exhaust gas, further improving the filtration effect of the exhaust gas filter.

[0009] To improve the filtration effect of exhaust gas:

[0010] The filter chamber is further configured such that a sealing cover is snapped onto the top of the filter chamber, two filter plates are inserted into the inside of the sealing cover, and a sealing ring is installed on the top of the filter plate, with the sealing ring fitting snugly against the top of the sealing cover.

[0011] By adopting the above technical solution, two detachable filter plates are set inside, which, together with the HEPA and activated carbon filter screens inside the filter plates, adsorb and filter particulate matter and harmful gases, thereby improving the filtration effect of the exhaust gas filter. At the same time, the detachable structure also makes it easy to replace the filter plates when needed.

[0012] To enable quick connection between the intake pipe and the connecting pipe:

[0013] The design is further configured such that the first flange, the second flange, the limiting groove, and the limiting protrusion are all annular structures, and when the inner wall of the first flange and the inner wall of the second flange are in contact with each other, the limiting groove and the limiting protrusion form an insertion connection structure.

[0014] By adopting the above technical solution, the two flanges are connected to each other in conjunction with the internal limiting grooves and limiting protrusions, which further improves the stability during docking and facilitates the rapid docking of the two flanges, thereby improving the docking efficiency between the two pipes.

[0015] To lock the connection between the two pipes:

[0016] The design is further configured such that: four locking screws are annularly installed on the inner wall of the limiting protrusion, and four corresponding through slots are penetrating the interior of the limiting groove; the locking screws and the through slots form a through-connection structure; and the locking nut is threadedly connected to the outer side of the locking screw and the outer wall of the first flange to form a fitting connection structure.

[0017] By adopting the above technical solution, a locking screw is installed in the second flange to lock the two flanges together with a locking nut, thereby locking the two pipes together, which facilitates the quick connection of the two pipes and improves the connection efficiency of the exhaust gas filter.

[0018] To further secure the connection between the two pipes:

[0019] Further configured as follows: the docking block is a U-shaped block structure, and the center of the docking block is threaded with a docking screw. When the first flange and the second flange are fitted together, the positions of the first slot and the second slot are corresponding to each other, and the first threaded groove and the second threaded groove are fitted together. The inner walls of the first threaded groove and the second threaded groove are provided with a continuous internal thread structure. The inner walls of the two ends of the U-shape of the docking block are respectively fitted together with the first slot and the second slot, and the docking screw and the first threaded groove and the second threaded groove form a threaded connection structure.

[0020] By adopting the above technical solution, four mating blocks are set on the outside of the two flanges to further lock the mating of the two flanges in conjunction with the mating screws, thereby improving the mating effect of the two flanges, and thus improving the mating effect between the air inlet pipe and the mating pipe inside the flange, avoiding leakage at the joint between the pipes, and thus improving the filtration effect of the exhaust gas filter.

[0033] In this embodiment, as Figure 3 , Figure 4 and Figure 5As shown, the first flange 301, the second flange 401, the limiting groove 302 and the limiting protrusion 402 are all annular structures, and when the inner wall of the first flange 301 and the inner wall of the second flange 401 are in contact with each other, the limiting groove 302 and the limiting protrusion 402 form an insertion connection structure.

[0034] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, four locking screws 405 are annularly installed on the inner wall of the limiting protrusion 402, and four corresponding through slots are penetrating the interior of the limiting groove 302.

It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0037] Therefore, the "centrifugal exhaust fan" and other components involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the automatic dipping machine of this application, in order to solve the corresponding technical problems to be solved by this application.
