Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a central dust collector filter element bracket. Background Art

[0002] With the vigorous development of industry, air pollution has become a very serious problem facing modern society. Air purification is also facing a very prominent problem. The dust content in the air continues to increase, and the harm to the human body is becoming increasingly serious. Therefore, environmentally friendly enterprises have followed this and more and more air filtration equipment and devices have begun to be produced. Air filters have therefore become a hot spot in production and manufacturing, and the design of the air filter bracket determines the overall structural style of the air filter.

[0003] The prior art also has the following defects during use:

[0004] 1. The air filter element bracket in the prior art is a single-layer bracket as a whole, and the overall structure is relatively weak. When facing the impact of a high-temperature gas or large particles, it is very easy to be damaged, thereby affecting the filtration efficiency. Frequently damaged air filters need to be checked and replaced regularly. When facing some external impacts, it is also very easy to cause deformation, thereby affecting production efficiency;

[0005] 2. The air filter element bracket in the prior art does have a protective effect on the air drainage as a whole. Although it has a large contact area as a whole, its air diversion efficiency is still relatively general. The low diversion efficiency has a greater impact on the purification efficiency of the air filter element, and it is unable to conduct effective diversion. Various substances contained in the air will adhere to the surface of the filter element, thereby affecting the long-term use of the filter element.

[0006] In view of this, we propose a central dust collector filter element bracket to solve the existing problems. Utility Model Content
