Description

Technical Field

[0001] This application relates to the field of air filter technology, and in particular to an air filter with a quick-pressing filter element. Background Technology

[0002] Air filters typically consist of an air inlet, filter element, partition plate, and air outlet. Ventilation openings in the partition plate divide the air filter into two chambers. The filter element is a consumable and requires regular maintenance or replacement. To ensure complete filtration, the filter element needs to completely cover the ventilation opening. This results in an overly tight connection between the filter element and the ventilation opening, hindering subsequent maintenance and replacement. Conversely, a design that allows for easy replacement would result in a looser connection between the filter element and the ventilation opening, preventing complete filtration.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The following is in conjunction with the appendix Figure 1-3This application provides a further detailed description. This application discloses an air filter with a rapid-pressing filter element, including a filter body 1 (as per prior art). The filter body 1 has a partition plate 2 dividing its interior into sealed upper and lower parts. The partition plate 2 has a ventilation opening, and a filter element 3 is located below the ventilation opening. The filter body 1 has an air outlet connected to the ventilation opening. The filter body 1 also has an air inlet located on the side of the filter element 3. Due to the partition plate 2, the filter body 1 is divided into two chambers, with the air inlet and outlet located at any position within these chambers. The application also includes a centrifugal fan located between the air outlet and the ventilation opening, and a dust collection bin located below the filter element 3. Unfiltered air enters the filter body 1 through the air inlet, is filtered by the filter element 3, and is then drawn away by the centrifugal fan through the ventilation opening, and the filtered air is delivered through the air outlet. Dust collected by the filter element 3 falls downwards into the dust collection bin. This application also includes a mounting bracket 4 to which the filter element 3 is connected. The filter body 1 is equipped with a support frame 5, and the support frame 5 is connected to a rotating rod 6. The rotating rod 6 has teeth, and the teeth can be directly set on the outer surface of the rotating rod 6, or... Figure 2 The embodiment shows a method of coaxially mounting a gear on the outer surface of the rotating rod 6, which means the rotating rod 6 has teeth. The filter body 1 also has a support plate 7, which includes a support part 701 and a drive part 702. The support part 701 is located below and in contact with the mounting bracket 4. The drive part 702 has a connecting part 703 that meshes with the teeth. The rotating rod 6 drives the support plate 7 to move vertically by rotation. Through the rotation of the rotating rod 6, the teeth of the rotating rod 6 drive the connecting part 703 of the support plate 7 to move vertically. The support part 701 of the support plate 7 supports the vertical movement of the mounting bracket 4, causing the filter element 3 mounted on the mounting bracket 4 to move closer to and be compressed towards the vent above the filter element 3. When the filter body 1 needs to work, the rotating rod 6 controls the filter element 3 to compress the vent to achieve a tight connection; when the filter body 1 needs maintenance or replacement of the filter element 3, the rotating rod 6 controls the filter element 3 to disengage from the vent compression state, facilitating replacement or maintenance of the filter element 3.

[0020] Furthermore, in order to constrain the movement direction of the support plate 7, the support frame 5 is provided with a vertical strip groove, and the driving part 702 of the support plate 7 is located in the strip groove. The lateral displacement of the support plate 7 is restricted by the two sides of the strip groove, so as to ensure that the support plate 7 moves in the vertical direction.

[0021] Furthermore, to ensure the rotation of the rotating rod 6, the support frame 5 can be connected to the rotating rod 6 using any existing rotating connection structure. In this embodiment, based on the engagement of the teeth of the rotating rod 6 with the connecting part 703 of the support plate 7, the support part 701 of the support plate 7 supports the mounting bracket 4. Under the combined weight of the mounting bracket 4 and the filter element 3 installed on the mounting bracket 4, the support plate 7 experiences downward pressure. The support frame 5 is provided with a U-shaped groove, and the rotating rod 6 is placed in the U-shaped groove. The rotating rod 6 is pressed into the U-shaped groove by the pressure of the support plate 7 itself, without affecting the rotation of the rotating rod 6, thus achieving an extremely simplified rotating connection structure. The support frame 5 can be set as a whole, or it can be like... Figure 2 As shown in the embodiment, there are multiple support frames 5, which are spaced apart and together support the rotating rod 6.

[0022] Furthermore, the rotating rod 6 is provided with teeth, and the connecting part 703 that meshes with the teeth can be a toothed rack; or it can be a hole that meshes with the teeth, and the meshing connection is achieved by inserting the teeth into the hole.

[0023] Furthermore, to facilitate the rotation of the rotating rod 6, a handle is provided at the end of the rotating rod 6. The handle is located outside the mounting bracket 4, and the rotation of the rotating rod 6 is controlled by controlling the handle.

[0024] Furthermore, to allow the support plate 7 to have both pressed and relaxed fixed states, a locking hole is provided in the handle, and a corresponding positioning hole is provided in the filter body 1. The locking hole is connected to the positioning hole via a pin. One positioning hole can be provided to determine the rotation angle of the rotating rod 6 in the pressed and locked state, and this pressed state is fixed by the pin. When the pin is released, under the pressure of the support plate 7, the rotating rod 6 automatically rotates to the rotation angle corresponding to the relaxed state. Alternatively, two positioning holes can be specifically provided to position the rotating rod 6 in the pressed and relaxed states respectively. The positioning holes can be extended to the set position using conventional connectors, such as a plate connected to the filter body 1.

[0025] Furthermore, a pulse cleaning device 8 is installed between the air outlet and the vent to clean the filter element 3. Specifically, the pulse cleaning device 8 includes a compressed air tank 801, which is connected to a pulse valve 802 via a pipe. The pulse valve 802 is connected to a pulse nozzle 803, with the outlet of the pulse nozzle 803 facing the vent. Since the air passing through the filter element 3 and the vent is already filtered, placing the pulse cleaning device 8 here prevents it from being contaminated by dust.

[0026] Furthermore, each filter element 3 is provided with two support frames 5, which are symmetrically arranged on both sides of the filter element 3. The number of support plates 7 and rotating rods 6 corresponds to the number of support frames 5. By symmetrically arranging support frames 5 and corresponding support plates 7 on both sides of the filter element 3, the filter element 3 can be evenly stressed when lifted and pressed, thus achieving a better tight connection with the ventilation opening.

[0027] Working principle: Install the filter element 3 into the mounting bracket 4 inside the filter body. Rotate the rotating rod 6 to raise the support plate 7. The support plate 7 presses against the mounting bracket 4 as it rises, making the filter element 3 fit tightly against the vent, so that the filter body 1 can start air filtration. When the rotating rod 6 lowers the support plate 7, the filter element 3 is no longer in close contact with the vent, making it easier to maintain or replace the filter element 3.
