Abstract

The invention discloses an air return energy-saving device for a fan. The device comprises an air return box, a mounting shell is connected to the surface of one end of the air return box, a net rackis arranged at the end of the mounting shell, a filtering isolation plate is connected to the inner side of the net rack, mounting blocks are fixed to the two sides of the net rack, storage grooves are formed in the bottoms of the mounting blocks, fixing plates are arranged in the storage grooves, and fixing blocks are connected to the two sides of the outer wall of the mounting shell; according to the invention, the designed fixing plates can be quickly clamped into the fixing grooves of the fixing blocks, so the filtering isolation plate can be quickly mounted and limited, and the situationthat a traditional mounting mode is too complex and prone to deviation is avoided; by means of the designed fixing blocks, the designed fixing blocks and the mounting blocks are attached to each other, so mounting of the filtering isolation plate is limited, and springs and the designed fixing plates are mounted and supported by means of the designed sliding rods.

Description

technical field

[0001] The invention belongs to the technical field of fan energy saving, and in particular relates to a return air energy saving device for a fan. Background technique

[0002] The fan coil return air box is mainly installed at the air outlet end of the fan. Its main function is to return air. It is a measure taken to save energy consumption and ensure the working effect of the fan. There is a lot of dust attached to the surface, which affects work efficiency.

[0003] When the existing fan coil return air box is in use, it isolates the inside and outside of it through the filter plate at the end to prevent the external dust from entering the inside of the box, and at the same time filter the dust in the air to ensure the cleanliness of the air However, when the existing filter isolation plate is installed, a large number of screws are used to fasten it around, which makes the installation complicated and increases the installation strength. At the same tim...
