Description

Technical Field

[0001] This utility model belongs to the technical field of potassium fluoride production equipment, and in particular relates to a high-efficiency air dust removal and filtration device. Background Technology

[0002] Traditional air dust removal devices have the following technical problems:

[0003] Insufficient filter plate sealing: Conventional filter plates mostly adopt a flat or cylindrical structure, which has poor adhesion to the inner wall of the shell, resulting in leakage of unfiltered air;

[0004] Low maintenance efficiency: Replacing the filter plates requires disassembling the outer shell or a complex transmission mechanism, increasing maintenance costs;

[0005] Uneven airflow distribution: The air inlet design is simple, which can easily create turbulence or dead zones in the filter. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency air dust removal and filtration device.

[0007] This utility model is achieved through the following technical solution:

[0008] A high-efficiency air dust removal and filtration device, comprising:

[0009] The outer shell has a central part that is shaped like a truncated quadrangular pyramid with a smaller top and a larger bottom. An air inlet is provided around the lower perimeter of the outer shell, and an air outlet is provided on the top surface.

[0010] The filter plate has a frustum-shaped shell structure that is larger at the top and smaller at the bottom, and multiple filter plates are arranged in a longitudinal array inside the shell;

[0011] The mounting structure is used to drive the filter plate to move longitudinally to seal against the inner wall of the housing and to limit the descent of the filter plate;

[0012] The fan is located inside the upper part of the casing.

[0013] To further realize this utility model, the following technical solutions may be preferred:

[0014] Preferably, the mounting structure includes a mounting rod vertically disposed at the center of the housing and a baffle horizontally slidably disposed on the mounting rod; the lower end of the filter plate is slidably fitted onto the mounting rod, and the mounting rod is longitudinally slidably disposed to drive the filter plate to move upward, so that the upper periphery of the filter plate is sealed and fitted against the inner wall of the housing; when the baffle extends out of the mounting rod, it prevents the filter plate from descending.

[0015] Preferably, the mounting structure further includes an opening and closing shaft, which is longitudinally slidably disposed inside the mounting rod, and its outer wall is provided with a plurality of frustum-shaped driving parts that are smaller at the top and larger at the bottom; when the opening and closing shaft moves upward, it pushes the baffle to extend laterally through the driving parts.

[0016] Preferably, a screw is rotatably connected to the lower part of the mounting rod, and the screw is threaded into the outer casing, so that the mounting rod can be driven to rise and fall by rotating the screw.

[0017] Preferably, the baffle has an elastic buffer layer on the side facing the filter plate, the elastic buffer layer having a thickness of 3-5 mm and being made of silicone material.

[0018] Preferably, rubber strips are provided around both the upper and lower peripheries of the filter plate.

[0019] The beneficial effects of this utility model through the above technical solution are:

[0020] This invention features excellent sealing and filtration efficiency. The four-sided frustum-shaped filter plate and the conical surface of the outer shell are designed to form an adaptive seal when the mounting rod is raised and lowered, preventing unfiltered air from bypassing. The longitudinally arrayed filter plates form a multi-level filtration gradient, which improves the dust retention rate by more than 30% compared with the traditional single-layer filtration structure.

[0021] This utility model is easy to maintain. The linkage mechanism between the baffle and the opening and closing shaft enables one-click locking / releasing of the filter plate, and the filter plate can be disassembled and assembled without tools. The screw lifting mechanism supports precise adjustment of the filter plate bonding pressure, extending the service life of the seals.

[0022] This invention enhances airflow dynamics. The four-sided truncated pyramid structure of the outer shell, combined with the lower circumferential air inlet, allows the airflow to diffuse evenly along the surface of the filter plate. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0033] Example 1:

[0034] like Figure 1-4 As shown, a high-efficiency air dust removal and filtration device includes a housing 1, a filter plate 2, and an installation structure 3. The housing 1 has a truncated quadrangular shape with a larger top and bottom in the middle. The filter plate 2 has a truncated quadrangular shell structure with a larger top and a smaller bottom. Multiple filter plates 2 are arranged in a longitudinal array inside the housing 1. The filter plates 2 are all fixed to the installation structure 3. The installation structure 3 drives the filter plates 2 to move upward, so that the upper periphery of the filter plate 2 is sealed and attached to the inner wall of the middle part of the housing 1.

[0035] The mounting structure 3 includes a mounting rod 31 and a baffle 32. The mounting rod 31 is vertically located at the center of the housing 1. The lower end of the filter plate 2 is slidably fitted onto the mounting rod 31. The baffle 32 is slidably mounted on the mounting rod 31. When the baffle 32 extends out of the mounting rod 31, it is used to prevent the filter plate 2 from descending.

[0036] The baffle 32 has an elastic buffer layer on the side facing the filter plate 2. The elastic buffer layer has a thickness of 3-5 mm and is made of silicone material.

[0037] The mounting rod 31 is longitudinally slidable. When the mounting rod 31 moves upward, the upper end of the filter plate 2 abuts against the inner wall of the outer shell 1. In this embodiment, a screw is rotatably provided at the lower part of the mounting rod 31. The screw is threaded into the outer shell 1. By rotating the screw, the mounting rod 31 is driven to rise and fall.

[0038] Rubber strips are provided around the upper and lower edges of the filter plate 2 to ensure the seal between the filter plate 2 and the outer shell 1 and the mounting rod 31.

[0039] The mounting structure 3 also includes an opening and closing mechanism, which includes an opening and closing shaft 33. The opening and closing shaft 33 is longitudinally slidably disposed inside the mounting rod 31. Multiple driving parts 331 are disposed in the middle of the opening and closing shaft 33. The number of driving parts 331 is equal to that of the filter plate 2 and they are arranged in a one-to-one correspondence. The driving parts 331 are in the shape of a frustum with a smaller top and a larger bottom. When the opening shaft moves upward relative to the mounting rod 31, the opening and closing part drives the baffle 32 to extend outward from the mounting rod 31.

[0040] The mounting rod 31 and baffle 32 are provided with an air outlet 12 on the top surface of the outer casing 1, an air inlet 11 is provided around the lower part of the outer casing 1, and a fan 4 is provided in the upper part of the inner casing 1.
