Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The labor intensity of workers is increased due to the difficulty in cleaning the dustproof screen of dryers, as conventional methods require regular manual cleaning, which is labor-intensive and inefficient.
Innovation Solution
A back-blowing unblocking device is introduced, comprising a high-pressure air main pipe, horizontal pipe, branch pipes, shunt connecting pipes, and fan-shaped nozzles, allowing for a non-stop, dense spray cleaning of the dustproof screen without manual intervention, reducing labor and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If manual cleaning of the dustproof screen is performed, then the dust accumulation problem is solved, but the labor intensity of workers increases
Solution Approach 1:
The dustproof screen cleaning system uses self-service principle by enabling the screen to clean itself through integrated back-blowing nozzles that spray high-pressure air directly onto the screen surface, eliminating the need for manual removal and cleaning by workers. The system automatically removes dust accumulation during or after the drying cycle without human intervention.
Solution Approach 2:
The invention applies pneumatic principle by using high-pressure air spray through back-blowing nozzles to remove dust from the dustproof screen. The air blowing device delivers focused high-velocity air streams that effectively dislodge and remove accumulated dust particles from the screen surface, solving the cleaning problem without mechanical contact.
2Manufacturing precision
If the dustproof screen is removed for cleaning, then thorough cleaning is achieved, but the cleaning process becomes more complex and time-consuming
Solution Approach 1:
The system performs preliminary cleaning action by spraying high-pressure air onto the dustproof screen during or immediately after the drying operation. This timing allows dust to be removed before it hardens or accumulates significantly, making cleaning easier and more effective without requiring screen removal or complex disassembly procedures.
Solution Approach 2:
The invention extracts the cleaning function from the main drying process by integrating a separate air blowing device with back-blowing nozzles specifically dedicated to screen cleaning. This extracted cleaning subsystem operates independently, allowing thorough cleaning without disrupting the primary drying operation or requiring complex coordinated procedures.
3Reliability
If regular manual cleaning is performed, then dust blocking is prevented, but productivity is reduced due to repeated cleaning interruptions
Solution Approach 1:
The air blowing cleaning system enables continuous operation by cleaning the dustproof screen in-situ during or after the drying cycle without interrupting the overall production process. The back-blowing nozzles maintain screen permeability continuously, preventing dust blocking from affecting subsequent drying operations and eliminating productivity losses from manual cleaning interruptions.

AI 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.
