[0018] Reference Figure 1-Figure 3A dust-free workshop return air structure comprises a return air duct 1, a fixing plate 2 is fixedly connected to the end of the return air duct 1, a fixing groove 3 is provided at one end of the fixing plate 2 away from the return air duct 1, and the fixing groove 3 and the fixing plate 2 are arranged in communication, a filter screen 4 corresponding to the fixing groove 3 is arranged on the inner side of the fixing groove 3, and mounting grooves are provided on the upper and lower inner walls of the fixing groove 3, and the position of the mounting groove corresponds to the filter screen 4, and a mounting plate 5 is arranged at the mounting groove, and each group of two mounting plates 5 is respectively arranged at the front and rear sides of the filter screen 4, and each mounting plate 5 Each of the mounting plates 5 penetrates the corresponding mounting groove and extends to the outside of the fixing plate 2. One end of each group of mounting plates 5 located on the outside of the fixing plate 2 is fixedly connected with a connecting plate 6. The filter 4 is installed in the fixing groove 3 on the fixing plate 2. The connecting plate 6 and the mounting plate 5 are extended toward the mounting groove, so that the mounting plate 5 passes through the mounting groove and extends into the fixing groove 3. The mounting plate 5 is located at the front and rear sides of the filter 4 to fix and clamp it. The filter 4 filters the air during the return air process to prevent dust from entering the workshop and affecting the production of the workshop.

[0019] One end of each connecting plate 6 close to the filter screen 4 is fixedly connected with a fixed plug rod 15, and fixed slots 13 corresponding to the fixed plug rod 15 are also provided at the upper and lower ends of the filter screen 4. Fixed card slots 14 are provided on the front and rear side walls of the filter screen 4, and fixed card blocks 16 corresponding to the fixed card slots 14 are provided on the side walls of each mounting plate 5. Each fixed card block 16 and fixed plug rod 15 as well as fixed card slots 14 and fixed slots 13 are frosted to improve the friction between the fixed card block 16 and the fixed card slot 14 and the fixed plug rod 15 and the fixed slot 13, so that they are fixed more firmly. The fixed plug rod 15 is inserted into the fixed slot 13, the mounting plate 5 is moved toward the direction of the fixed plate 2, and the fixed card block 16 is inserted into the fixed card slot 14 to fix the filter screen 4;
