Description

Technical Field

[0001] The utility model relates to a rigidity-enhanced air filter, belonging to the technical field of air filters. Background Art

[0002] Air filters are mainly used in pneumatic machinery, internal combustion machinery and other fields. Their function is to provide clean air for these mechanical equipment to prevent them from inhaling air with impurity particles during operation, thereby increasing the chance of abrasion and damage. The working requirements of air filters are to be able to undertake high-efficiency air filtration work, not to add too much resistance to air flow, and to be able to work continuously for a long time.

[0003] According to the authorized patent CN202321902896.3, this patent reduces the shaking of multiple rows of filter plates, and the protective baffles on both sides protect the filter plates from collision, so that the overall filter assembly of the device is strong, durable and rigid. However, the filter element is protected by the baffle. When the filter element needs to be cleaned or repaired, it will be troublesome to disassemble because the baffle is fixed to the outside of the filter element by screws, and larger particles of impurities filtered by the filter box will remain inside the filter box, which will make cleaning more time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to provide a rigidity-enhanced air filter. The utility model has a simple structure and is easy to use. It can protect the filter element while facilitating the disassembly of the protective device, so that the filter element can be quickly cleaned or repaired, and the foreign particles accumulated at the bottom of the filter box can be completely cleaned to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A rigidity-enhanced air filter comprises a filter box, the top of which is fixedly connected to an air duct, the top of which is mounted a filter element body, the top of which is mounted a protective mechanism, the outside of which is fixedly connected to an air intake pipe, and the inside of which is provided with a cleaning mechanism.

[0007] The protective mechanism includes a movable groove, the interior of the movable groove is slidably connected with a sliding rod, the outer side of the sliding rod is fixedly connected with a return spring, the top of the sliding rod is fixedly connected with a No. 1 clamping frame and a No. 2 clamping frame, the outer side of the filter box is fixedly connected with an L-shaped plate, the outer side of the L-shaped plate is fixedly connected with a threaded tube, the inner part of the threaded tube is threadedly connected with a screw, the outer side of the screw is fixedly connected with a pushing plate, the outer side of the No. 1 clamping frame is fixedly connected with a clamping rod, and a positioning hole is opened inside the No. 2 clamping frame.

[0008] The cleaning mechanism comprises a sealing plate, a pulling rod is fixedly connected to the outer side of the sealing plate, a pressing spring is fixedly connected to the outer side of the pressing spring, and a sliding plate is fixedly connected to the outer side of the pressing spring.

[0009] Furthermore, a filter plate is installed inside the filter box, and the air duct is located below the filter element body. The air introduced by the intake pipe can be filtered through the filter plate inside the filter box, so that larger particles of dust are filtered into the interior of the filter box, and the filtered gas then enters the interior of the filter element body through the air duct.

[0010] Furthermore, the movable grooves are symmetrically distributed in the inner top wall of the filter box, and one end of the return spring away from the slide rod is fixedly connected to the inner wall of the movable groove. Through the coordinated use of the slide rod and the return spring, the slide rod can drive the No. 1 clamping frame and the No. 2 clamping frame to move on the top of the filter box.

[0011] Furthermore, the No. 1 clamping frame and the No. 2 clamping frame are symmetrically distributed on the outside of the filter element body, and the pushing plate is located on the outside of the No. 1 clamping frame and the No. 2 clamping frame. The screw is rotated and moved inside the threaded tube, so that the screw drives the pushing plate to move. At this time, the pushing plate will squeeze the No. 1 clamping frame and the No. 2 clamping frame.

[0012] Furthermore, the clamping rod and the positioning hole are on the same plane, and the outer diameter of the clamping rod is smaller than the inner diameter of the positioning hole. When the clamping rod enters the interior of the positioning hole, the connection stability between the first clamping frame and the second clamping frame can be enhanced.

[0013] Furthermore, the sealing plate is clamped in the inner wall of the filter box, and the pulling rod is located inside the filter box. The movement of the sealing plate can drive the pulling rod to move inside the filter box, thereby causing the pulling rod to drive the sliding plate to move.

[0014] Furthermore, the sliding plate is installed on the inner wall of the filter box through an extrusion spring, and the sliding plate is slidably connected to the inside of the filter box. The elasticity of the extrusion spring itself makes the initial position of the sliding plate on the inner wall of the filter box, and the sliding plate can be driven to move inside the filter box by pulling the rod, thereby pushing impurities to the connection between the sealing plate and the filter box.

[0015] The beneficial effects of the utility model are:

[0016] , the utility model is provided with a filter box, and a filter element body is installed on the top of the filter box, and the screw is first rotated to make the screw rotate and move inside the threaded tube, and then the screw will drive the push plate to move, so that the push plate pushes the No. 1 clamping frame and the No. 2 clamping frame, and then the No. 1 clamping frame and the No. 2 clamping frame will move on the top of the filter box under the action of the sliding rod, and when the No. 1 clamping frame and the No. 2 clamping frame are close to each other, they can protect the filter element body on the top of the filter box, and the clamping rod will also enter the interior of the positioning hole to keep the No. 1 clamping frame and the No. 2 clamping frame stable, and when the filter element body needs to be cleaned or repaired, it is only necessary to reverse the screw to make the push plate move away from the No. 1 clamping frame and the No. 2 clamping frame, and then the sliding rod will drive the No. 1 clamping frame and the No. 2 clamping frame away from the filter element body under the action of the reset spring, so that the filter element body can be easily cleaned or repaired.

[0017] The utility model sets up a filter box, firstly introduces the gas generated by the engine into the interior of the filter box through the air intake pipe outside the filter box, and because a filter plate is installed inside the filter box, larger dust particles will be filtered to the inner bottom of the filter box. When it is necessary to clean the dust particles inside the filter box, first pull the sealing plate to make the sealing plate drive the pulling rod to move inside the filter box, and then use the pulling rod in conjunction with the extrusion spring to make the pulling rod drive the sliding plate to move inside the filter box, so that impurities are pushed to the connection between the sealing plate and the filter box, thereby achieving the effect of fully cleaning the dust at the bottom of the filter box.
