[0002] Cartridge dust collectors typically consist of an inlet, a filter element, and an outlet. The filter element is a consumable and requires regular maintenance or replacement. To ensure complete filtration, the dust collector includes a partition plate between the outlet and the filter element, with dedicated ventilation openings in the partition plate. The filter element is then connected to the outlet, completely covering the ventilation openings. If the connection between the filter element and the ventilation opening is too tight, it hinders subsequent maintenance and replacement. Conversely, a design that allows for easy replacement may result in a loose connection between the filter element and the ventilation opening, failing to achieve complete filtration. Utility Model Content

[0016] 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.
[0017] The following is in conjunction with the appendix Figure 1-4This application provides a further detailed description. An embodiment of this application discloses a high-efficiency cartridge dust collector, comprising a body 1, with a partition plate 2 inside the body 1. The partition plate 2 has ventilation openings, dividing the space inside the body 1 into two independent chambers, connected by the ventilation openings. A filter element 3 is located below the ventilation openings. The body 1 has an air inlet and an air outlet, with the air outlet communicating with the ventilation openings. The air inlet is located on the side of the filter element 3. Air entering the body 1 is filtered by the filter element 3, and the filtered air passes through the ventilation openings and exits from the air outlet. The application also includes a mounting bracket 4, on which the filter element 3 is mounted. Two L-shaped plates 5 are symmetrically arranged on both sides of the ventilation openings, each L-shaped plate 5 forming a U-shaped groove with the lower surface of the partition plate 2, and the openings of the two U-shaped grooves are oriented opposite to each other. The mounting bracket 4 is slidably connected to both U-shaped grooves, allowing the mounting bracket 4 to be supported by both U-shaped grooves simultaneously. By sliding the mounting bracket 4 into the U-shaped groove, the mounting bracket 4 can be quickly installed into the U-shaped groove and quickly removed from the U-shaped groove, thereby realizing the quick installation and quick removal of the filter element 3.
[0018] To achieve a sliding connection between the mounting bracket 4 and the U-shaped groove, the two sides of the U-shaped groove cannot clamp the mounting bracket 4 tightly. This results in a gap between the mounting bracket 4 and the upper side of the U-shaped groove, meaning the mounting bracket 4 cannot tightly adhere to the partition plate 2, causing the filter element 3 to not tightly adhere to the ventilation opening. To solve this problem, a support frame 6 is provided at the bottom of the filter element 3. The support frame 6 is connected to a rotating rod, which is connected to a control block 601. The control block 601 has a apex, and a support plate 7 is provided above the control block 601. The support plate 7 contacts the bottom of the filter element 3, and the distance between the apex and the axis of the rotating rod is greater than the distance between the support plate 7 and the axis of the rotating rod. Specifically, the axis of the rotating rod is perpendicular to the vertical direction of the up-and-down movement of the support plate 7, and parallel to the extension direction of the L-shaped plate 5. When the rotating rod rotates and the apex of the control block 601 is above the rotating rod, because the distance between the apex and the axis of the rotating rod is greater than the distance between the support plate 7 and the axis of the rotating rod, the apex of the control block 601 lifts the support plate 7, causing the support plate 7 to move upward. The support plate 7 contacts the bottom of the filter element 3. The support plate 7 moves upward, causing the filter element 3 to move upward, so that the filter element 3 is pressed tightly against the vent, thus achieving the effect of pressing the filter element 3.
[0019] Furthermore, to ensure the rotating rod can rotate, the support frame 6 can be connected to the rotating rod using any existing rotating connection structure. In this embodiment, the support frame 6 has an upward-facing U-shaped groove, in which the rotating rod is placed. Since the support plate 7 is located above the rotating rod, the rotating rod will not disengage from the U-shaped groove of the support frame 6 under the constraint of the support plate 7, allowing the rotating rod to rotate freely within the U-shaped groove of the support frame 6.
[0020] Furthermore, to facilitate the operation of the rotating rod, a handle 602 is provided at the end of the rotating rod. The handle 602 is located outside the support frame 6, and the rotation of the rotating rod is controlled by operating the handle 602.
[0021] Furthermore, the weight of the filter element 3 and the support plate 7 generates downward pressure, which forces the rotating rod to rotate through the control block 601, preventing the apex of the control block 601 from maintaining a fixed position. To lock the position of the control block 601, the body 1 is provided with a limiting mechanism that cooperates with the handle 602. The limiting mechanism restricts the rotation of the handle 602, controls the rotation angle of the rotating rod, and thus fixes the apex position of the control block 601. Specifically, the limiting mechanism can be a pin, for example, a positioning plate with a positioning hole inside the main body 1. Inserting the pin into the positioning hole prevents the handle 602 from swinging in the opposite direction, thus preventing the rotating rod from rotating in the opposite direction. Removing the pin allows the rotating rod to rotate freely again. Alternatively, it can be a U-shaped pin, with the distance between the two sides of the U-shaped pin greater than the width of the handle 602, fixing the handle 602 in a specific position. The limiting mechanism can also be an elastic buckle, for example, a positioning plate inside the main body 1 with a buckle connected to it by a spring. The buckle end has an inclined guide surface facing the movement trajectory of the handle 602. When the handle 602 contacts the buckle end, the inclined guide surface guides the buckle to retract towards the positioning plate. When the handle 602 swings past the inclined guide surface at the buckle end, the spring pushes the buckle out, thus limiting the swing of the handle 602. Equivalent or similar conventional technologies are all acceptable.
[0022] Furthermore, a dust removal device 10 is provided between the air outlet and the vent to clean the filter element 3. Since the space between the vent and the air outlet contains only filtered air, placing the dust removal device 10 in this area helps prevent contamination and reduces the need for later maintenance.
[0023] Specifically, the dust removal device 10 includes a compressed air tank (not shown in the figure), which is connected to a pulse valve 1001 via a pipe. The pulse valve 1001 is connected to a pulse nozzle 1002, with the outlet of the pulse nozzle 1002 facing the vent. Compressed air is ejected through the pulse nozzle 1002 and blown onto the filter element 3, blowing off the contaminants adsorbed by the filter element 3 during filtration. Furthermore, the jet direction of the pulse nozzle 1002 is from the clean chamber between the air outlet and the vent to the contaminated air chamber containing the filter element 3, which can prevent dust contamination from flowing backward from the filter element 3 towards the vent during cleaning.
[0024] Furthermore, the bottom of the filter element 3 is typically equipped with a conventional collection device 8, such as a collection hopper or collection box. A dust collection bin 9 is placed at the output port of the collection device 8. Unlike conventional technologies, in this embodiment, the collection device 8 and the dust collection bin 9 are connected by a connector 801 to improve the sealing between them and prevent dust and other contaminants from scattering and causing pollution when they fall from the collection device 8 into the dust collection bin 9. The connector 801 is an openable and closable annular structure.
[0025] Specifically, connector 801 consists of two arc-shaped plates that fit together in a ring shape, and the two arc-shaped plates are hinged together. The two arc-shaped plates are hinged together by a latch hinge, which can both open and close the two arc-shaped plates and lock them in place.
[0026] The control block 601 can be any shape existing in the art, as long as it has a vertex and the distance between the vertex of the control block 601 and the axis of the rotating rod is greater than the distance between any other point of the control block 601 and the axis of the rotating rod, such as a common cam.
[0027] Working Principle: The filter element 3 is installed on the mounting bracket 4 and inserted into the U-shaped groove formed by the partition plate 2 and the L-shaped plate 5. The operating handle 602 controls the rotation of the rotating rod, moving the apex of the control block 601 directly above the rotating rod. This causes the apex of the control block 601 to lift the support plate 7, which in turn lifts the filter element 3, ensuring a tight fit between the filter element 3 and the vent. The blower is activated to blow air into the air inlet, or the exhaust fan is activated to draw air from the air outlet. The air enters the main body 1, is filtered by the filter element 3, passes through the vent, and exits from the air outlet. When the filter element 3 needs to be replaced, the operating handle 602 rotates the rotating rod, causing the apex of the control block 601 to disengage from the state where it lifts the support plate 7. Under the pressure of the filter element 3 and its own weight, the support plate 7 moves downward, releasing the mounting bracket 4 from its compressed state. After pulling out the mounting bracket 4 along the extension direction of the U-shaped groove formed by the partition plate 2 and the L-shaped plate 5, the filter element 3 installed on the mounting bracket 4 can be removed and replaced.
