[0002] Inspection sieves are widely used in laboratories and industrial production, serving as crucial equipment for quality control and playing a vital role in ensuring product quality and improving production efficiency. In the past, with smaller industrial production scales and lower levels of automation, the discharge of material from inspection sieves relied primarily on manual sampling at regular intervals in the workshop. Samples were then sent to the laboratory for sieve analysis, and the workshop would adjust its processes based on the experimental results. This process consumed significant manpower and time, resulting in high labor intensity for workers and low testing accuracy and efficiency.

After the oversize chute 3 has been used for a period of time... Then, the inner wall of the sieve 3 is purged by the purging unit. The specific purging process is as follows: Open the one-way valve 13 on the purging inlet 2 and the purging outlet 12, and blow air into the sieve 3 through the purging inlet 2 to purge the sieve 3. The material adhering to the inner wall of the sieve 3 is blown off and sent into the dust collector. Regularly cleaning the sieve 3 can not only prevent the material adhering to the sieve 3 from affecting the discharge speed, but also prevent it from affecting the test results.

[0026] Working principle: When the inspection screen body 1 screens materials, the oversize material enters the oversize chute 3 through the oversize material outlet on the inspection screen body 1. The flow meter 4 monitors the flow rate of the oversize material in the oversize chute 3 in real time. The lighting lamp 504 illuminates the inclined tube section 302. The laser scanner 502 scans the oversize material in the inclined tube section 302 and converts the image data into digital data. The data processing unit in the controller receives the data information from the flow meter 4 and the laser scanner 502, and uses algorithms to analyze and process it. The analysis and processing results are sent to the user interface, so that the user can know the flow rate and particle size distribution of the oversize material in the oversize chute 3 in a timely manner, which facilitates timely adjustment of production process parameters and improves the processing capacity and production efficiency of the inspection screen oversize material.

[0027] After the screen chute 3 has been used for a period of time, the conveying pipe 6 is separated from the screen chute 3, the cleaning mechanism 9 is inserted into the screen chute 3, and the receiving box 15 is placed on the base 7 so that the receiving box 15 is directly below the screen chute 3. The screen material adhering to the transparent glass plate 11 is cleaned off by the cleaning mechanism 9, and the cleaned material is collected by the receiving box 15. Then, air is introduced into the screen chute 3 through the blowing unit to blow off the material adhering to the inner wall of the screen chute 3 and send it into the dust collector. The specific cleaning and blowing processes have been described in detail above and will not be repeated here.
