Description

Technical Field

[0001] This utility model relates to the technical field of dust collector filtration devices, and in particular to a filtration device for an aramid high-temperature dust collector. Background Technology

[0002] In many industrial production processes, such as steel smelting, thermal power generation, and cement production, a large amount of high-temperature dust-laden gas is generated. The dust in these high-temperature gases not only pollutes the environment but may also affect the normal operation and service life of production equipment.

[0003] Traditional dust collector filtration devices have certain limitations in terms of high temperature resistance and cannot meet the requirements for long-term stable operation under high temperature conditions. Aramid fibers have excellent high temperature resistance, high strength and chemical stability. Applying them to dust collector filtration devices can effectively improve the performance and reliability of the filtration devices in high temperature environments.

[0004] However, existing filter devices use a modular installation structure for the filter cartridges. The advantage of this structure is that multiple cartridges or a single cartridge can be installed as needed during use. However, existing filter cartridges do not have a sealing structure, so there are dead zones in the filtration process.

[0005] Therefore, this utility model proposes a filter device for an aramid high-temperature dust collector. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and propose a filtration device for aramid high-temperature dust collectors.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a filter device for an aramid high-temperature dust collector, comprising:

[0008] A filter cartridge assembly, which consists of a filter ring cylinder and mounting plates disposed on both sides;

[0009] The fixing component consists of an annular rotating frame and a sleeve rotatably connected to the mounting plate. A connecting rod is provided between the annular rotating frame and the sleeve, and a fixing shaft is provided inside the connecting rod.

[0010] The mounting assembly consists of two arc-shaped mounting plates, each with a mounting block at both ends, and a mounting bolt between the two mounting blocks.

[0011] Furthermore, the internal width of the arc-shaped mounting plate is adapted to the width of the two mounting plates connected to each other.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by snapping the two arc-shaped mounting plates onto the outside of the two adjacent mounting plates, the two mounting plates are limited, thus preventing the two filter cartridge assemblies from separating during use and causing filtration dead angles.

[0013] Furthermore, there are two mounting bolts, and the two mounting bolts are symmetrical about the center of the arc-shaped mounting plate.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the two mounting bolts, the two arc-shaped mounting plates are limited, preventing the two mounting bolts from separating during use and causing the two filter cartridge assemblies to detach.

[0015] Furthermore, there are three connecting rods in total, and the three connecting rods are arranged in a ring, with the included angle between any two adjacent connecting rods being equal.

[0016] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the connecting rod, the sleeve used for installation and mounting is positioned at the center of the annular rotating frame.

[0017] Furthermore, a sealing ring is provided at the ends of the two mounting plates that are far apart from each other.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the sealing ring, it improves the sealing performance between the mounting plate and the equipment connection, or the sealing effect between two mounting plates.

[0019] Furthermore, the inner wall of the mounting plate is provided with a groove, and the annular rotating frame is rotatably connected to the inner wall of the mounting plate through the groove.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the groove, the annular rotating frame can be rotatably connected to the mounting plate during use. At this time, after the fixed shaft is fixed, the mounting plate rotates on the annular rotating frame.

[0021] Furthermore, a fixing disc is provided at one end of the fixing shaft.

[0022] The beneficial effect of adopting the above-mentioned further solution is that, under the action of the fixing plate, the fixing shaft is fixed in the filter chamber of the filter device, so that the fixing shaft is connected and fixed to the filter device.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. In this utility model, under the action of the fixing component, the fixing shaft is first connected and fixed to the filter chamber of the filter device by the fixing plate. After the fixing is completed, the material is filtered by the filter cylinder assembly. When the material enters the filter chamber, the flowing gas will drive the filter ring cylinder to rotate. When the mounting plate is subjected to rotational power, it rotates on the ring rotating frame, so that the filter ring cylinder is in full contact with the material, improving the utilization rate of the filter ring cylinder and increasing the filtration effect.

[0025] 2. In this utility model, under the action of the mounting components, after the two filter cartridge components are attached to each other, the two arc-shaped mounting plates are respectively snapped onto the two sides of the two mounting plates to limit the distance between the two mounting plates. When the two mounting plates are attached to each other, the sealing effect is improved under the action of the sealing ring. Furthermore, the mounting bolt is threaded between the two attached mounting blocks to limit the distance between the two arc-shaped mounting plates and prevent the two arc-shaped mounting plates from separating during use.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0035] like Figure 1-4 As shown, this utility model provides a technical solution: a filter device for an aramid high-temperature dust collector, comprising:

[0036] The filter cartridge assembly 1 consists of a filter ring cylinder 12 and mounting plates 11 disposed on both sides.

[0037] The fixing component 2 consists of an annular rotating frame 24 and a sleeve 22 rotatably connected inside the mounting plate 11. A connecting rod 23 is provided between the annular rotating frame 24 and the sleeve 22, and a fixing shaft 21 is provided inside the connecting rod 23.

[0038] Mounting component 3 consists of two arc-shaped mounting plates 31, each with a mounting block 32 at both ends. A mounting bolt 33 is positioned between the two mounting blocks 32. Three connecting rods 23 are arranged in a ring, with equal angles between adjacent connecting rods 23. Under the action of fixing component 2, fixing shaft 21 is first connected and fixed to the filter chamber of the filter device via fixing plate 211. After fixing, material is filtered through filter cartridge assembly 1. When the material enters the filter chamber, the flowing gas drives the filter ring 12 to rotate. When mounting plate 11 is subjected to rotational power, it rotates on the annular rotating frame 24, allowing the filter ring 12 to fully contact the material, improving the utilization rate of the filter ring 12 and increasing the filtration effect.

[0039] Furthermore, such as Figure 2 - Figure 4 As shown: The internal width of the arc-shaped mounting plate 31 is adapted to the width of the two mounting plates 11 connected to each other. There are two mounting bolts 33, and the two mounting bolts 33 are symmetrical about the center of the arc-shaped mounting plate 31. The ends of the two mounting plates 11 that are far apart from each other are provided with sealing rings 13. Under the action of the mounting assembly 3, after the two filter cartridge assemblies 1 are put into contact with each other, the two arc-shaped mounting plates 31 are respectively snapped into the two sides of the two mounting plates 11, limiting the position between the two mounting plates 11. When the two mounting plates 11 are put into contact with each other, the sealing effect is improved under the action of the sealing rings 13. The mounting bolts 33 are further threaded between the two mounting blocks 32 that are put into contact with each other, limiting the position between the two arc-shaped mounting plates 31 and preventing the two arc-shaped mounting plates 31 from separating during use.

[0040] The above solution still has a problem with the connection between the annular rotating frame 24 and the mounting plate 11, such as... Figure 3 As shown: In this solution, the inner wall of the mounting plate 11 is provided with a groove, and the annular rotating frame 24 is rotatably connected to the inner wall of the mounting plate 11 through the groove. Under the action of the groove, the annular rotating frame 24 can be rotatably connected to the mounting plate 11 during use. At this time, when the fixed shaft 21 is fixed, the mounting plate 11 rotates on the annular rotating frame 24.

[0041] The above solutions still have the problem of fixing the fixed shaft 21, such as... Figure 2 As shown: In this scheme, a fixing disk 211 is provided at one end of the fixing shaft 21. Under the action of the fixing disk 211, the fixing shaft 21 is fixed in the filter chamber of the filter device, so that the fixing shaft 21 is connected and fixed to the filter device.

[0042] Working principle: such as Figure 1-4 As shown, firstly, the fixed shaft 21 is fixed in the filter chamber by the fixed plate 211. Secondly, several filter cartridge assemblies 1 are inserted into the fixed shaft 21 through the sleeve 22. At this time, two adjacent arc-shaped mounting plates 31 are snapped onto two adjacent mounting plates 11 to limit the mounting plates 11. The arc-shaped mounting plates 31 are then bolted and fixed by the mounting bolts 33. After fixing, the filter chamber door is closed. During the filtration process, the material comes into contact with the filter ring cylinder 12 and drives the filter ring cylinder 12 and the mounting plate 11 to rotate on the annular rotating frame 24, thereby increasing the contact area between the filter ring cylinder 12 and the material and improving the utilization rate of the filter ring cylinder 12.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
