Description

A dust removal device for mortar production for convenient disassembly of filter screen

technical field

The utility model relates to the field of dust-removing boxes, in particular to a dust-removing device for mortar production which is convenient for disassembling filter screens.

Background technique

Mortar is a material used to level or connect adjacent bricks in buildings. Mortar can be divided into on-site mixing mortar and ready-mixed dry powder plastering mortar. A large amount of dust will be generated during the mortar production process, which will seriously pollute the environment, and a device is needed to remove dust from the dust.

Although the existing dust removal device has many advantages, it is found that the following deficiencies still exist in the process of use:

1. The filter screen inside the existing dust removal device is usually directly installed inside the box body of the dust removal device. When disassembling and replacing the filter screen, it is necessary to open the corresponding box door on the box body for replacement, which is not very convenient to operate;

2. Since the filter screen is installed inside the box of the dust removal device, it is necessary to stop the dust removal device when disassembling and replacing the filter screen, so as to prevent the door from being unable to be opened due to excessive suction inside the box, and the shutdown state The dust removal device cannot continue the dust removal work, which affects the normal operation of the work and is inconvenient to use;

Therefore, we propose a dust removal device for mortar production that is convenient to disassemble the filter screen to solve the above-mentioned problems.
