Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, in particular to a dust removal filter bag convenient for fixing. Background Technique

[0002] With the increasing environmental awareness of people, various environmental protection equipment has emerged in the public eye like mushrooms after rain. The most common one is the dust removal cloth bag. The dust removal cloth bag can be regarded as the heart of the bag filter, and is generally called the filter dust bag, dust removal filter bag, dust collection bag, dust accumulation bag, dust removal bag, dust collector cloth bag, etc. The dust removal cloth bag is a key part in the operation process of the bag filter. Usually, the cylindrical filter bag is vertically suspended in the dust collector. Its fixing method is like a dust removal filter bag convenient for fixing with the application number 201811537665.0. When in use, the cylindrical filter bag is fixed by threads. And there are often a large number of cylindrical filter bags to be fixed inside a filter bag dust collector. When using threads for fixing, it is necessary to rotate the cylindrical filter bag many times, and it is rather troublesome to fix a large number of cylindrical filter bags. Therefore, in view of this problem, a dust removal filter bag convenient for fixing is needed for improvement. Content of the Utility Model

[0011] 1. When it is necessary to disassemble or install the filter bag in the present utility model, only need to push the extrusion sleeve so that the notch position of the extrusion sleeve can be aligned with the limiting ball. When the notch of the extrusion sleeve is aligned with the limiting ball, at this time, the limiting ball is not restricted and can move and shake freely, and thus cannot catch the limiting groove. At this time, the connecting sleeve and the filter bag can be disassembled freely. When it is necessary to fix the filter bag, only need to insert the connecting sleeve into the fixed sleeve, and then loosen the extrusion sleeve so that the spring pushes the extrusion sleeve to reset. At this time, the limiting ball can be snapped into the limiting groove, and thus the fixing of the filter bag can be quickly completed. In this way, the whole installation process is convenient and fast, and there is no need to frequently rotate any components.

[0012] 2. The whole installation process of the present utility model is not only convenient and fast, but also the whole device is relatively simple to operate. The staff does not need to specifically learn the operation, which is convenient for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-5 , the present invention provides a technical solution: a dust removal filter bag that is convenient to fix, including a fixed plate 1. A filter bag 2 is arranged at the lower end of the fixed plate 1. A fixing mechanism for fixing the filter bag 2 is arranged between the fixed plate 1 and the filter bag 2. The fixing mechanism includes a fixed sleeve 3, a connecting sleeve 4, a card slot 5, a limiting ball 6, an extrusion sleeve 7, a notch 8, and a limiting groove 9. A plurality of fixed sleeves 3 are evenly and fixedly arranged at the lower end of the fixed plate 1. One end of the filter bag 2 is fixedly provided with a connecting sleeve 4. A plurality of card slots 5 are evenly opened inside the fixed sleeve 3. Limiting balls 6 are movably clamped inside the card slots 5. An extrusion sleeve 7 is movably sleeved on the outer surface of the fixed sleeve 3. A notch 8 is arranged on one side inside the extrusion sleeve 7. A limiting groove 9 is opened on the outer surface of the connecting sleeve 4.

[0021] A limiting ring 10 is arranged on the outer surface of the fixed sleeve 3. A spring 11 is arranged between the limiting ring 10 and the extrusion sleeve 7 on the outer surface of the fixed sleeve 3. The spring 11 can automatically push the extrusion sleeve 7 to reset, so that the notch 8 position of the extrusion sleeve 7 can automatically be misaligned with the limiting ball 6;

[0022] A plurality of through holes 12 are evenly and fixedly arranged on the outer surface of the upper end of the fixed plate 1. Through the through holes 12, the flue gas filtered by the filter bag 2 can be conveniently discharged from the middle of the filter bag 2 to form an air flow cycle;

[0023] Both the fixed sleeve 3 and the connecting sleeve 4 are hollow inside. The hollow fixed sleeve 3 and connecting sleeve 4 can facilitate the passage of flue gas;

[0024] A chamfer is arranged on the outer surface of the connecting sleeve 4. Through the chamfer, the connecting sleeve 4 can be conveniently inserted into the fixed sleeve 3, so that the installation can be further facilitated;

[0025] Mounting holes 13 are provided at the four corners of the outer surface of the fixing plate 1. Through the mounting holes 13, the whole device can be conveniently fixed inside the bag filter 2. At this time, the lower end of the fixing plate 1 is the flue gas waiting to be filtered, and the upper end of the fixing plate 1 is the clean flue gas after filtration.

[0026] Working principle: When using this device, the whole device can be conveniently fixed inside the bag filter 2 through the mounting holes 13. At this time, the lower end of the fixing plate 1 is the flue gas waiting to be filtered, and the upper end of the fixing plate 1 is the clean flue gas after filtration.

[0027] Moreover, the bag filter 2 used for filtration in this device is convenient for installation and disassembly. When it is necessary to disassemble or install the bag filter 2, only need to push the extrusion sleeve 7 so that the notch 8 of the extrusion sleeve 7 can be aligned with the limit ball 6. When the notch 8 of the extrusion sleeve 7 is aligned with the limit ball 6, at this time, the limit ball 6 is not restricted and can move and shake freely, and thus cannot catch the limit groove 9. At this time, the connecting sleeve 4 and the bag filter 2 can be freely disassembled. When it is necessary to fix the bag filter 2, only need to insert the connecting sleeve 4 into the fixing sleeve 3, and then release the extrusion sleeve 7, so that the spring 11 pushes the extrusion sleeve 7 to reset. At this time, the limit ball 6 can be snapped into the limit groove 9. In this way, the fixing of the bag filter 2 can be quickly completed. In this way, the whole installation process is convenient and fast, without frequent rotation of any components, and the whole device is relatively simple to operate. The staff does not need to specifically learn the operation, which is convenient for popularization and use.
