Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter plates, and in particular to a pesticide residue detection permeate filter plate. Background Technology
[0002] The development of agricultural industrialization has made agricultural production increasingly reliant on exogenous substances such as pesticides, antibiotics, and hormones. Excessive pesticide residues affect consumer safety, and when using testing machines to detect pesticide residues in soil, percolation plates are needed to obtain pure liquid.
[0003] While existing percolation plates can be fixed to the top of the detector with screws for easy collection of pure liquid in the lower container, other problems exist during use. For example, they lack electric heating, and some soil may experience slow internal liquid flow or freezing due to environmental factors. Waiting for the liquid to flow downwards naturally is inefficient and requires a long waiting time, reducing the percolation quality of the filter plate. Furthermore, cleaning the interior is inconvenient, as soil residue remains in the upper cylinder after percolation. Cleaning requires removal from the detector, which necessitates the use of tools, making the process time-consuming and labor-intensive. To address these issues, we propose a pesticide residue detection percolation plate. Utility Model Content
[0004] The purpose of this invention is to provide a pesticide residue detection percolation plate that solves the problems of existing percolation plates lacking electric heating function and being inconvenient to clean internally.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pesticide residue detection percolation plate, including a frame box, in which a filter element and a top cover are respectively placed inside and at the top of the frame box. A limiting plate is symmetrically welded inside the frame box. A fixing cylinder is welded through the top of the top cover. Two connecting plates are arranged inside the top cover. A limiting pin is welded to one side of the connecting plate. A limiting spring is bolted between the other side of the connecting plate and the top cover through a spring fixing piece. A filter screen is installed inside the fixing cylinder. Two fixing ring plates are fixedly sleeved on the surface of the fixing cylinder. A resistance wire is installed on the surface of the fixing cylinder. A protective plate is bolted between the two fixing ring plates.
[0006] The above technical solution provides rapid heating, which facilitates the separation of the test substance, accelerates the detection efficiency, and makes internal cleaning easier. It is simple and labor-saving to operate, increases the efficiency of personnel, and is highly practical.
[0007] The present invention is further configured such that: mounting plates are welded to both sides of the frame box, and mounting holes are provided on the top of the mounting plates.
[0008] By adopting the above technical solution, the installation plate and mounting holes make it easy for personnel to fix the filter plate with screws.
[0009] The present invention is further configured such that: pull plates are provided on both sides of the top cover, and a fixing rod is symmetrically welded to one side of the pull plate, and the other end of the fixing rod is welded to the connecting plate.
[0010] By adopting the above technical solution, the connection plate can be easily pulled outward by personnel through the setting of the pull plate and the fixing rod.
[0011] The present invention is further configured such that the surfaces of the frame box and the top cover are coated with anti-corrosion coating.
[0012] By adopting the above technical solution and applying anti-corrosion coating, the anti-corrosion and moisture-proof effects of the frame box and top cover surface can be improved.
[0013] The present invention is further configured such that: the filter element has a limiting groove inside for use with the limiting plate.
[0014] By adopting the above technical solution, the filter element can be positioned by setting the limiting groove, preventing the filter element from shifting due to shaking in the frame box.
[0015] The present invention is further configured such that the filter screen is made of stainless steel.
[0016] Using the above technical solution, the filter screen has the characteristics of high strength, low density and excellent corrosion resistance.
[0017] The present invention is further configured such that the limiting spring is made of carbon spring steel.
[0018] Using the above technical solution, the limit spring has the characteristics of excellent mechanical properties, good resistance to spring reduction, low temperature resistance and corrosion resistance.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. This utility model first fixes the filter plate with screws. After the filter plate is fixed, the soil to be tested is put into the fixed cylinder. After the soil is put in, the resistance wire is activated. After the resistance wire is energized, it generates heat energy. After the heat energy is generated, it is transferred to the filter screen through the fixed cylinder. It has a rapid heating function, which can promote the separation process of the test object and speed up the detection efficiency.
[0021] 2. This utility model allows users to grasp two pull plates with both hands and pull them outwards. As the pull plates are pulled outwards, the connecting plate moves outwards under the fixation of the fixing rod. When the connecting plate moves outwards, it not only compresses the limiting spring, causing it to contract and deform, but also causes the limiting pin to separate from the through hole in the limiting plate. Once the pull plates are pulled out to the end, they can be lifted upwards. This facilitates internal cleaning, is simple and labor-saving, speeds up the work efficiency of personnel, and is highly practical. Attached Figure Description

A limiting pin 7 is welded to one side of the connecting plate 6, and a limiting spring 8 is bolted between the other side of the connecting plate 6 and the top cover 3 via a spring fixing plate. By grasping the two pull plates 15 with both hands and pulling them outwards, the pull plates 15, under the fixation of the fixing rod 14, will drive the connecting plates 6 to move outwards. When the connecting plates 6 move outwards, they will not only compress the limiting spring 8, causing it to contract and deform, but also cause the limiting pin 7 to separate from the through hole in the limiting plate 4. When the pull plates 15 are pulled out to the end, they can be lifted upwards. This facilitates internal cleaning, is simple and labor-saving, speeds up personnel work efficiency, and is highly practical.

[0034] Brief description of the usage process: By grasping the two pull plates 15 with both hands and pulling them outward, the pull plates 15 will move the connecting plate 6 outward under the fixation of the fixing rod 14. When the connecting plate 6 moves outward, it will not only compress the limiting spring 8 to cause it to contract and deform, but also cause the limiting pin 7 to separate from the through hole in the limiting plate 4. When the pull plate 15 is pulled out to the end, it can be lifted up.
[0035] Example 2:
[0036] refer to Figure 1 and Figure 2 A pesticide residue detection percolation plate is disclosed. A filter screen 9 is installed inside a fixed cylinder 5.

A protective plate 12 is bolted between the two fixed ring plates 10. The filter plate is first fixed with screws. After the filter plate is fixed, the soil to be tested is put into the fixed cylinder 5. After the soil is put in, the resistance wire 11 is activated. The resistance wire 11 generates heat energy after being energized. The heat energy is then transferred through the fixed cylinder 5 to the filter screen 9, providing a rapid heating function, which can promote the separation process of the analyte and accelerate the detection efficiency.
[0037] refer to Figure 1 and Figure 2The filter screen 9 is made of stainless steel and features high strength, low density and excellent corrosion resistance.
