Bag type air filter

Abstract

The invention provides a bag type air filter. The bag type air filter comprises an outer frame, a filter bag and a pressing frame, the outer frame comprises a filter basket flange provided with a filter basket support and a filter basket of which one end is connected with the filter basket flange; the filter basket is of a grid support frame structure; the filter bag comprises a filter bag flange attached to the filter basket flange and a filter bag connected with the filter bag flange and located in the filter frame; the pressing frame comprises a sealing flange attached to the filter bag flange and a sealing support arranged in the sealing flange; and the sealing flange, the filter bag flange and the filter basket flange are detachably and hermetically connected. The bag type air filter has the advantages that the bag type air filter is reasonable in structure and convenient to disassemble and assemble, only the filter bag needs to be replaced, other parts can be repeatedly used, and the production cost and the transportation cost are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of air filtration, and in particular relates to a bag type air filter. Background technique [0002] With the continuous development of the world economy, the demand and reliance on air filters in various environmental spaces are increasing. In the process of using countless air filters, it is necessary to pay a lot of money for purchase, logistics, equipment operation, and waste. Treatment and other links, repeated consumption, the cost is quite high, and a large amount of waste treatment is also contrary to our advocacy of environmental protection, energy conservation and emission reduction. [0003] In this case, it is very meaningful and valuable to develop an environmentally friendly air filter that can not only reduce the cost of use, improve the filtration performance, but also help save energy and reduce emissions. [0004] At present, the primary and medium-efficiency bag filters on the market are ...

AI Technical Summary

Problems solved by technology

[0004] At present, the primary and medium-efficiency bag filters on the market are made of several single-piece bags with filter materials, and then fixed together on a small frame to form a bag filter; when in use, the small frame Clamped on the installation frame, fix and support the entire filter bag, and at the same time seal with the installation frame, so that the air passes through the filter material to achieve the purpose of filtration (such as figure 1 As shown), this structure has the following problems: 1. The frame is disposable and cannot be reused, which increases the production cost; 2. Multiple single-piece bags need to be installed one by one, with many processing procedures and high labor costs; 3. .It needs to be packaged and transported after the overall installation, and the packaging volume is large, which increases the logistics cost; 4. The filter bag lacks support, the shape is unstable, and the fit of the air outlet surface reduces the use area, increases the resistance, reduces the service life, and affects the filtration efficiency at the same time , which in turn increases the energy consumption of the equipment; 5. Both the filter bag and the frame need to be replaced when replacing, which increases the amount of waste, causes waste of resources, and increases the cost of waste treatment
