Abstract
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. 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.
