Description

Technical Field

[0001] This utility model relates to the field of detection and filtration technology, specifically a filtration device for detecting the quality and safety of agricultural products. Background Technology

[0002] In the process of agricultural product cultivation, chemical agents are often sprayed to control pests and diseases. Therefore, pesticide residue testing is an essential part of agricultural product quality and safety testing. To test for pesticide residues, the fibrous tissue of the agricultural product to be tested needs to be pulverized, and the pulverized slurry is filtered and collected. Then, a solvent is added to the slurry to extract the pesticide components for testing.

[0003] In existing technologies, residual fibers in the slurry can clog the filter pores during filtration, affecting filtration efficiency. Furthermore, the slurry is often first crushed, filtered, and collected in one container, and then the solvent and slurry are mixed in another container. Separating the slurry collection and solvent mixing operations reduces the efficiency of agricultural product quality and safety testing.

[0004] For example, the filtering device for testing the quality and safety of agricultural products disclosed in announcement number CN220473137U allows agricultural product tissue to be added into the filter cylinder through a feeding pipe. By operating a servo motor, the agricultural product tissue can be crushed, the inner wall of the filter cylinder can be scraped, and the filter cylinder can be rotated simultaneously. This improves the crushing effect of the agricultural product tissue and prevents the filter cylinder from clogging. At the same time, the centrifugal force generated by the rotation of the filter cylinder facilitates the outflow of slurry and can mix the slurry with the solvent for extracting pesticide components, thereby improving the pesticide extraction effect. The overall structural design is simple and reasonable, and its practicality is improved.

[0005] However, the device cannot clean the inner wall of the chamber during use, causing impurities to adhere to the inner wall and affect the test results of the next agricultural product.

[0006] Therefore, we urgently need to provide a filtration device for testing the quality and safety of agricultural products. Utility Model Content
