Description

Technical Field

[0001] The utility model relates to the technical field of dust recovery, in particular to a dust recovery and reuse system for non - intumescent fire - retardant coatings. Background Art

[0002] Non - intumescent fire - retardant coatings are coatings that can improve the fire - resistance of materials, slow down the spread speed of flame propagation, or prevent combustion within a certain period of time by brushing the coatings on the surfaces of flammable materials. This type of coating is called fire - retardant coating.

[0003] During the production process of fire - retardant coatings, a mixing bin is required to mix raw materials. During continuous mixing and feeding, dust will float out, which will cause harm to the physical health of workers. Therefore, a dust - proof mechanism is needed for dust - proof treatment. For example, the utility model patent with the publication number CN211725007U discloses a dust - removing mechanism for fire - retardant coating production, which includes a dust - removing box body, a dust - removing cover matched with the dust - removing box body, an L - shaped ventilation pipe, and support blocks fixedly arranged at the four corners of the bottom end of the dust - removing box body. A first exhaust fan and a second exhaust fan are fixedly installed in the inner cavity of the ventilation pipe. A fixing plate is fixedly arranged at the top end of the inner cavity of the dust - removing box body. A cylindrical filter net is fixedly sleeved in the middle of the fixing plate. A sheet - shaped filter net is detachably arranged at the top end of the cylindrical filter net. One end of the ventilation pipe is communicated with the cylindrical filter net. A vibration mechanism for vibrating the dust on the cylindrical filter net is arranged on the inner wall of the dust - removing box body.

[0004] In the above - mentioned prior art, when continuously mixing the coating, although the dust - removing mechanism can handle the scattered dust, after the dust removal, it is not convenient to directly recycle the collected dust. The collected dust needs to be taken out of the dust - removing mechanism first and then recycled. Such an operation process is also more troublesome, thus affecting the recycling efficiency.

[0058] 3. In the present utility model, through the arrangement of the auxiliary cleaning mechanism, during the rotation of the support column, the third bevel gear can be driven to move around the fourth bevel gear, so that the third bevel gear, the driving rod and the second bevel gear can be driven to rotate by the meshing of the third bevel gear and the fourth bevel gear.
