A dust collector bag that is easy to connect and fix

Abstract

This utility model relates to the field of dust collector bag technology, specifically a dust collector bag that is easy to connect and fix. It includes a bag body fitted onto a bag frame. The bag body is characterized by a steel wire ring at its top, and multiple sets of rubber strips fixed to the inner wall of the bag body, with grooves on the surface of the rubber strips. The beneficial effect is that by integrally forming a cloth cover around the top of the bag body, and setting steel wire rings on the top and bottom surfaces of the inner wall of the cloth cover, during installation, after fitting the bag body onto the bag frame, pulling downwards causes the cloth cover to fit over the top of the frame. Using pliers, the steel wire rings are twisted through the cloth cover, tightly securing them to the top ring of the bag frame. Simultaneously, the rubber sleeve on the inner ring of the cloth cover increases the friction between it and the top ring of the frame, further strengthening the connection and effectively preventing the bag body from falling off during use, ensuring stable dust collection.

Description

Technical Field

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

[0002] In the field of industrial dust removal, filter bags are the core filtration component of baghouse dust collectors, and the connection and fixation between the filter bag and the bag cage directly affects the dust removal efficiency and the stability of equipment operation. Traditionally, when installing filter bags onto the bag cage, the bag is simply placed over the cage, relying on the friction between the bag and the cage to maintain the connection. However, this connection method has many drawbacks: during the operation of the dust removal equipment, factors such as airflow impact and equipment vibration can easily cause the bag to detach from the bag cage, leading to malfunction of the dust removal system and affecting production progress. Traditional connection methods cannot guarantee a tight seal between the bag and the cage, allowing dust-laden gas to leak from the connection gaps, reducing dust removal efficiency and increasing subsequent treatment costs.

[0003] Therefore, developing a dust collector bag that is easy to connect and securely fasten is of great practical significance. Utility Model Content

[0004] The purpose of this invention is to provide a dust collector bag that is easy to connect and fix, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust collector bag that is easy to connect and fix, comprising a bag body fitted onto a bag frame, characterized in that: a steel wire ring is provided at the top of the bag body, and multiple sets of rubber strips are fixed to the inner wall of the bag body, with grooves formed on the surface of the rubber strips.

[0006] Preferably, the top of the bag body is integrally formed with a wrapping cloth cover, and the inner wall of the wrapping cloth cover is provided with two steel wire rings, which are respectively fixed to the top surface and the bottom surface inside the wrapping cloth cover.

[0007] Preferably, a rubber sleeve is fixed to the inner ring surface of the wrapping cloth cover, and a reserved groove is opened on the inner ring surface of the rubber sleeve. The reserved groove is an arc-shaped annular groove and is used to fit onto the top ring of the cloth bag frame.

[0008] Preferably, the rubber strip is an arc-shaped strip, and multiple sets of rubber strips are arranged vertically. Each set of rubber strips has multiple strips, and the multiple rubber strips are arranged in a circular shape. The rubber strips are located between two adjacent vertical bars of the bag frame.

[0009] Preferably, the slot is an arc-shaped groove with a round opening at the end, and the slot is fastened to the reinforcing ring of the bag frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model proposes a dust collector bag that is easy to connect and fix. It features an integrally formed cloth cover at the top of the bag body, with steel wire rings on the top and bottom surfaces of the inner wall of the cloth cover. During installation, after the bag body is placed on the bag frame, it is pulled downwards to secure the cloth cover to the top of the frame. Using pliers, the steel wire rings are twisted through the cloth cover, tightly gripping the top ring of the bag frame. Simultaneously, the rubber sleeve on the inner ring of the cloth cover increases the friction between it and the top ring of the frame, further strengthening the connection and effectively preventing the bag from falling off during use, ensuring stable dust collection.

[0012] The arc-shaped annular groove on the inner surface of the rubber sleeve allows for a better fit with the top ring of the bag filter frame, forming a good sealing structure. This reduces leakage of dust-laden gas from the connection point, improves dust removal efficiency, lowers subsequent processing costs, and ensures a clean production environment. Multiple sets of arc-shaped rubber strips fixed to the inner wall of the bag are arranged vertically, with each set containing multiple strips distributed circumferentially between two adjacent vertical members of the bag filter frame. Pushing the rubber strips causes their surface grooves to engage with the reinforcing ring of the bag filter frame, further enhancing the connection stability between the bag and the frame. This allows the bag to better withstand the impact of airflow and equipment vibration during dust removal, extending the service life of the filter bag. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a dust collector bag that is easy to connect and fix, including a bag body 1, which is fitted onto a bag frame. The top of the bag body 1 is provided with a wire ring 3. A wrapping cloth cover 2 is integrally formed on the top of the bag body 1. The inner wall of the wrapping cloth cover 2 is provided with two wire rings 3, which are respectively fixed to the top surface and the bottom surface inside the wrapping cloth cover 2. A rubber sleeve 4 is fixed to the inner ring surface of the wrapping cloth cover 2. A reserved groove 5 is opened on the inner ring surface of the rubber sleeve 4. The reserved groove 5 is an arc-shaped annular groove and is used to fit onto the top ring of the bag frame. Place the bag body 1 onto the bag frame from bottom to top. After the bottom of the bag body 1 is blocked at the bottom of the bag frame, pull the bag body 1 downward so that the wrapping cloth cover 2 is placed on the top of the bag frame, and the rubber sleeve 4 is between the wrapping cloth cover 2 and the top ring of the bag frame. Use pliers to clamp the wire ring 3 through the wrapping cloth cover 2 and twist it. The wire ring 3 is tightly wrapped on the top ring of the bag frame. The rubber sleeve 4 increases friction, so that the wrapping cloth cover 2 is firmly limited on the top ring of the bag frame, so that the bag body 1 will not fall off.

[0021] Multiple sets of rubber strips 6 are fixed to the inner wall of the bag body 1. The surface of the rubber strips 6 is provided with grooves 7. The rubber strips 6 are arc-shaped strips, and multiple sets of rubber strips 6 are arranged vertically. Each set of rubber strips 6 has multiple strips, and the multiple rubber strips 6 are arranged in a circumferential shape. The rubber strips 6 are located between two adjacent vertical bars of the bag frame. The grooves 7 are arc-shaped grooves with round openings. The grooves 7 are fastened to the reinforcing ring of the bag frame. Pushing the rubber strips 6 causes the grooves 7 on the surface of the rubber strips 6 to fasten to the reinforcing ring of the bag frame, thereby improving the firmness of the bag body 1 after being fitted onto the bag frame.

[0022] Method for using the dust collector bag for easy connection and fixation: Place the bag body 1 onto the bag frame from bottom to top until the bottom of the bag body 1 is blocked by the bottom of the bag frame. Pull the bag body 1 downwards so that the wrapping cloth cover 2 is placed on top of the bag frame. At this time, the rubber sleeve 4 is between the wrapping cloth cover 2 and the top ring of the bag frame. Use pliers to clamp the wire ring 3 through the wrapping cloth cover 2 and twist it. Since there are two wire rings 3, one fixed to the top surface and the other to the bottom surface inside the wrapping cloth cover 2, after twisting, the wire ring 3 is tightly clamped onto the top ring of the bag frame. At the same time, the rubber sleeve 4 increases friction, so that the wrapping cloth cover 2 is firmly fixed on the top ring of the bag frame, preventing the bag body 1 from falling off. Multiple sets of rubber strips 6 are fixed to the inner wall of the bag body 1. The rubber strips 6 are arc-shaped and arranged vertically. Each set of rubber strips 6 has multiple strips, arranged in a circumferential pattern, and the rubber strips 6 are located between two adjacent vertical bars of the bag frame. Push the rubber strip 6 so that the groove 7 on the surface of the rubber strip 6 (the groove 7 is an arc groove with a round opening at the end) is fastened to the reinforcing ring of the bag frame, thereby improving the firmness of the bag body 1 after being fitted onto the bag frame.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
