[0001] This utility model relates to the field of dust collector bag technology, specifically a dust collector bag that is easy to disassemble and replace. Background Technology

[0002] Dust collector bags primarily serve to filter dust, purify air, protect equipment, and promote environmental protection. Dust collector bags are considered the heart of a baghouse dust collector and are generally referred to as dust collector bags or dust filter bags. They are a crucial component in the operation of a baghouse dust collector. Existing dust collector bags are prone to dust leakage at the connection points between the bags and the holes in the support plate, affecting the purification effect. Furthermore, the existing bag frames are not extendable, making transportation inconvenient. Additionally, the frames are directly attached to the bags, making them difficult to separate and disassemble later, thus affecting the efficiency of bag replacement. Utility Model Content

[0003] The purpose of this utility model is to provide a dust collector bag that is easy to disassemble and replace, in order to solve the problems mentioned in the background art, such as the existing dust collector bag and the hole connection on the support plate are prone to dust leakage, which affects the purification effect. In addition, the existing dust collector bag frame cannot be extended or retracted, which is not convenient for transportation. At the same time, the frame is directly attached to the dust collector bag, which is not easy to separate and disassemble later, thus affecting the replacement efficiency of the dust collector bag.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dust collector bag that is easy to disassemble and replace, comprising a support plate, a dust collector bag assembly passing through the support plate, a bag skeleton structure passing through the dust collector bag assembly, the dust collector bag assembly including a limiting strip, a dust collector bag body fixed to the lower side of the limiting strip, and a rebound spring sheet embedded in the dust collector bag body.

[0005] Preferably, the bag frame structure includes a sealing limiting plate, an auxiliary limiting component and a frame component are fixed on the sealing limiting plate, the frame component is located below the auxiliary limiting component, a sealing ring is embedded on the lower side of the sealing limiting plate, a handle is fixed on the upper side of the sealing limiting plate, and a base plate is fixed on the lower side of the frame component.

[0006] Preferably, the auxiliary limiting component includes a fixing rod, and a fixing block is fixed to the lower side of the fixing rod. The fixing block can adjust the position of the arc-shaped limiting plate by means of a telescopic structure.

[0007] By adopting the above technical solution, the connection between the support plate and the dust collector bag body is sealed by setting an auxiliary limiting component.

[0008] Preferably, the skeleton assembly includes a skeleton telescopic rod, a hollow threaded connector is threaded onto the skeleton telescopic rod, and rollers are fixed on the skeleton telescopic rod.

[0009] By adopting the above technical solution, the skeleton can be stretched and adjusted by setting skeleton components.

[0010] Preferably, the base plate is arranged in a hollow annular shape.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the dust collector bag is easy to disassemble and replace.

[0012] (1) It is equipped with a dust collector bag assembly and an auxiliary limiting assembly. The dust collector bag body is limited and fixed by the setting of the limiting strip and the spring sheet. The hydraulic cylinder on the fixing block drives the arc-shaped limiting plate to continue to move through the hydraulic rod, thereby performing auxiliary limiting and sealing of the dust collector bag body and the support plate. Finally, the sealing ring on the arc-shaped limiting plate is used to seal again, thereby avoiding dust leakage and affecting the dust removal effect.

[0013] (2) It is equipped with a frame assembly and is fixed by a three-section frame telescopic rod, which facilitates transportation and movement. With the assistance of multiple sets of rollers, the frame is prevented from directly adhering to the dust collector bag body, which would make it difficult to disassemble later and affect the replacement of the dust collector bag body.

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a dust collector bag that is easy to disassemble and replace, such as... Figure 1 , Figure 2 and Figure 4 As shown, it includes a support plate 1, through which a dust collector bag assembly 2 passes. The dust collector bag assembly 2 includes a limiting strip 21, and a dust collector bag body 22 is fixed to the lower side of the limiting strip 21. A rebound spring sheet 23 is embedded in the dust collector bag body 22.

[0022] Among them, the support plate 1 has a circular hole, and the circular hole limits the position of the dust collector bag body 22.

[0023] Specifically, the dust collector bag body 22 is arranged in a ring shape, and the spring plate 23 on the dust collector bag body 22 is arranged in a ring shape. The outer diameter of the spring plate 23 is the same as the inner diameter of the hole opened on the support plate 1.

[0024] In the above scheme, the dust collector bag body 22 passes through the hole opened on the support plate 1, the rebound spring sheet 23 on the dust collector bag body 22 is attached to the inner wall of the hole opened on the support plate 1, and the limiting strip 21 on the upper side of the dust collector bag body 22 limits the dust collector bag assembly 2.

[0025] like Figure 1 , Figure 3 and Figure 5 As shown, a bag frame structure 3 runs through the dust collector bag assembly 2. The bag frame structure 3 includes a sealing limiting plate 31. An auxiliary limiting component 32 and a frame assembly 35 are fixed on the sealing limiting plate 31. The frame assembly 35 is located below the auxiliary limiting component 32. A sealing ring 33 is embedded on the lower side of the sealing limiting plate 31. A handle 34 is fixed on the upper side of the sealing limiting plate 31. A base plate 36 is fixed on the lower side of the frame assembly 35. The auxiliary limiting component 32 includes a fixing rod 321. A fixing block 322 is fixed on the lower side of the fixing rod 321. The fixing block 322 adjusts the position of the arc-shaped limiting plate 323 by telescopic structure.

[0026] In this application, the telescopic structure is a hydraulic cylinder, which is the prior art. The fixing block 322 is arranged in a ring, and five sets of hydraulic cylinders are fixed on the fixing block 322. The five sets of hydraulic cylinders drive the arc-shaped limiting plate 323 to move towards each other through the hydraulic rod, thereby limiting the connection between the support plate 1 and the dust collector bag body 22 through the arc-shaped limiting plate 323, thereby assisting in the sealing and limiting function.

[0027] Specifically, a limiting groove is provided on the lower side of the sealing limiting plate 31. The limiting groove limits and seals the limiting strip 21, thereby playing an auxiliary sealing role with the assistance of the sealing ring 33 on the sealing limiting plate 31.

[0028] Furthermore, the handle 34 fixed on the upper side of the fixing rod 321 is U-shaped. The handle 34 is designed to facilitate the simultaneous rotation of multiple lifting devices and the removal of the entire frame, thus eliminating the need for manual handling and saving the entire replacement time, thereby increasing practicality.

[0029] In the above scheme, the skeleton component 35 on the sealing limiting plate 31 passes through the hole opened in the support plate 1. With the assistance of the sealing limiting plate 31, the limiting strip 21 is assisted in limiting the position. With the assistance of the sealing ring 33 on the sealing limiting plate 31, the sealing ring 33 on the sealing limiting plate 31 plays an auxiliary sealing role. With the assistance of the hydraulic cylinder on the upper side of the fixing block 322 on the fixing rod 321, the arc-shaped limiting plate 323 is driven to move towards each other through the hydraulic rod. Finally, the arc-shaped limiting plate 323 limits and fixes the dust collector bag body 22 on the hole opened in the support plate 1, thereby sealing the dust collector bag body 22 and the hole opened in the support plate 1 to prevent dust leakage. The operator hangs the hanger on the handle 34 to facilitate the direct disassembly of the skeleton later.

[0030] like Figure 1 As shown, the frame assembly 35 includes a frame telescopic rod 351, a hollow threaded connector 352 is threaded onto the frame telescopic rod 351, a roller 353 is fixed on the frame telescopic rod 351, and the base plate 36 is annularly hollow.

[0031] Among them, there are five sets of skeleton telescopic rods 351, which are equally distributed on the base plate 36, and each set of skeleton telescopic rods 351 is arranged in three sections.

[0032] Specifically, two sets of connecting rods are fixed on the base plate 36, and the two sets of connecting rods are symmetrically arranged about the central axis of the base plate 36;

[0033] In the above scheme, the worker pulls the frame telescopic rod 351 to extend it to the required length. After the hollow threaded connector 352 is rotated to fix the connection of the frame telescopic rod 351, the base plate 36 plays a supporting and limiting role. With the assistance of the roller 353 on the frame telescopic rod 351, it plays a guiding role and prevents the frame telescopic rod 351 from directly contacting the dust collector bag body 22, ensuring that the dust collector bag body 22 can be properly separated from the frame telescopic rod 351, thus increasing practicality.

[0034] Working principle: When using this easy-to-disassemble and replace dust collector bag, connect the external power supply. By setting up the dust collector bag assembly 2 and the bag frame structure 3, the dust collector bag can be used normally for dust removal. The bag frame structure 3 is easy to handle and easy to disassemble from the dust collector bag assembly 2.
