Summary: | A back-blowing unblocking device for the dustproof screen of the dryer, a dustproof equipment, and a dryer are provided. The back-blowing unblocking device for the dustproof screen of the dryer utilizes a closed compartment space of the dryer. The back-blowing unblocking device for the dustproof screen of the dryer includes a high-pressure air main pipe, a high-pressure air horizontal pipe, high-pressure air branch pipes, a shunt connecting pipe, and back-blowing fan-shaped nozzles. Except for the back-blowing fan-shaped nozzles, all others are welded and formed by stainless steel pipe materials. A length of each high-pressure air branch pipe is equal to a length of an A-shaped dustproof screen. Both ends of the each high-pressure air branch pipe are closed and an upper center opening is welded to the shunt connecting pipe. Both sides of the each high-pressure air branch pipe are densely arranged with the back-blowing fan-shaped nozzles. A row number of the high-pressure air branch pipe is equal to a segment number of the A-shaped dustproof screen. The back-blowing unblocking device for the dustproof screen of the dryer is mounted on the dustproof screen. The high-pressure air main pipe is connected with an air source valve through a hose. The present invention solves a problem of difficulty in cleaning a dustproof screen of a dryer in an art known to inventors. |
