Description

Technical Field

[0001] The utility model relates to the technical field of insecticide production, and more specifically to a grinding medium filtering device for the production of imidacloprid suspension seed coating agent. Background Art

[0002] Imidacloprid suspension seed dressing agent is a suspension seed dressing agent processed with imidacloprid as the active ingredient. Imidacloprid is a nitromethylene systemic insecticide that acts on the acetylcholine receptors in the synaptic site of the insect nervous system, interfering with the pest's motor nervous system and causing the chemical signal transmission to fail. In addition to imidacloprid, the seed dressing agent also contains film-forming agents, dispersants, stabilizers, antifreeze agents and other auxiliary ingredients. On the one hand, these ingredients can make the active ingredients such as imidacloprid evenly adhere to the surface of the seeds to form a firm drug film; on the other hand, they can ensure the stability of the seed dressing agent during storage and use. During the production process, the raw materials may bring in some mechanical impurities, incompletely dissolved substances or wear particles generated during the grinding process, etc. These impurities will not only affect the appearance and quality of the seed dressing agent, but may also clog the nozzle of the spray equipment or affect the uniformity of the seed coating during use. The plate and frame filter press can effectively intercept and remove these impurities, thereby achieving solid-liquid separation and ensuring the purity of the seed dressing agent.

[0003] On the filter frame of a traditional plate and frame filter press, the filter is generally fixed to the filter frame by means of bolts, nuts or clips. When the filter needs to be replaced, the specific positions of the bolts or clips used for fixing must be found first, and then the corresponding tools are used to perform the corresponding operations. For example, if it is fixed by bolts and nuts, the bolts can be rotated counterclockwise with a wrench to gradually loosen them. If a clip structure is used, it is necessary to press or pull out the clips one by one to release the fastening effect of the clip on the filter. Therefore, the traditional filter replacement operation process is time-consuming, which in turn leads to the extension of the production time of the imidacloprid suspension seed coating agent.

[0024] In the present embodiment, by setting a pressure frame 4 and a positioning assembly 14, after the piston rod 5 is inserted into the inside of the socket 9 through the through hole 6, the sealing plate 12 can be slid by sliding the positioning assembly 14, so that the inside of the sealing groove 11 is in a negative pressure state, and the surface of the pressure frame 4 can be tightly attached to the surface of the filter 3, so that the filter 3 can be quickly installed, and the snap-fitting fixing method can apply pressure to one side of the filter 3, thereby improving the sealing between the filter 3 and the filter frame 2 and improving the filtering effect.

[0025] Specifically, the positioning assembly 14 includes a sliding seat 141 slidably connected to the inside of the sliding groove 16, the inner surface of the sliding seat 141 is penetrated by a sliding hole 142 and a limiting hole 143, the interior of the sliding seat 141 is provided with a limiting groove 144 and a sealing cavity 149, a spring 145 is movably installed inside the limiting groove 144, the internal sealing sliding connection of the limiting groove 144 is provided with a limiting plate 146, the surface of the limiting plate 146 is fixedly connected with a sealing column 147, the surface of the sealing column 147 is fixedly connected with a positioning tooth plate 148, the internal sealing sliding connection of the sealing cavity 149 is provided with a sealing block 1410, and the surface of the sealing block 1410 is fixedly connected with a convex plate 1411.

[0026] In this embodiment, by setting a clamping structure between the positioning tooth plate 148 and the fixed tooth plate 17, the sliding of the sliding seat 141 can be positioned, and the sliding position of the sealing plate 12 can be limited, so that the internal air pressure of the sealing groove 11 is in a stable state, thereby improving the stability of the pressure frame 4 and the filter frame 2 after assembly and enhancing practicality.
