Description

TECHNICAL FIELD

[0001] The utility model relates to a remove impurity equipment technical field especially for dicyanopropionic acid ethyl ester production's remove impurity equipment. BACKGROUND

[0002] The remove impurity equipment for dicyanopropionic acid ethyl ester production is a mechanical equipment specially designed to remove impurities in liquid raw materials during the production of dicyanopropionic acid ethyl ester. The main goal of this equipment is to improve the purity of the product and ensure that the quality and performance of the final product meet the standards.

[0003] Most of the existing remove impurity equipment for dicyanopropionic acid ethyl ester production only uses single-layer filter structure, which cannot effectively remove all impurities in the raw materials, especially small particles and suspended solids, thus easily leading to insufficient purity of the final product and affecting product quality. SUMMARY

[0004] The utility model aims at providing a remove impurity equipment for dicyanopropionic acid ethyl ester production, which realizes the effect of improving the purity of ethyl cyano-propionate raw materials, to solve the problem of poor purity of ethyl cyano-propionate raw materials in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A remove impurity equipment for dicyanopropionic acid ethyl ester production, comprising a shell, a recess is provided on the upper end of the shell, and a filter screen is fixedly connected inside the shell; an upper cover is arranged inside the recess, a cavity is provided inside the upper cover, a plurality of holes are arranged in an annular array at the lower end of the upper cover, and the holes are in communication with the cavity; a lower cover is arranged at the lower end of the shell, a filter cartridge is fixedly connected to the upper end of the lower cover, a pump body is fixedly connected to the lower end of the lower cover, a pipeline is fixedly connected through the inside of the lower cover, the lower end of the pipeline is in communication with the input end of the pump body, and the output end of the pump body is fixedly connected with a conveying pipe.

[0007] Preferably, a motor is fixedly connected to the side wall of the shell, and a gear is rotatably connected to the inside of the side wall of the shell.

[0008] Preferably, a plurality of gear slots are arranged at the lower end of the upper cover, and the gear slots are arranged in an annular array, and the side wall of the gear cooperates with the gear slots.

[0009] Preferably, a feed pipe is fixedly connected through the upper end of the upper cover, the lower end of the feed pipe is in communication with the inside of the cavity, and the inside bottom of the cavity is conical.

[0010] Preferably, the lower end of the housing is provided with a groove, the groove is convex, the side wall of the lower cover is threadedly connected to the inner wall of the groove, and the filter cylinder is slidably connected to the groove.

[0011] Preferably, a handle is fixedly connected to the lower end of the lower cover, and the handle glove is located outside the pump body.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The ethyl dicyanopropionate raw material inside the cavity flows into the shell through multiple holes. The raw material undergoes preliminary filtration and impurity removal through the filter screen, removing larger impurities. During the flow of the raw material into the shell, the gear driven by the motor rotates. The toothed blocks on the side wall of the gear push the tooth groove, causing the top cover to rotate inside the groove. This ensures that the raw material discharged through the holes can be evenly distributed and in contact with the filter screen, thus preventing impurities from accumulating and clogging the filter screen in one place. At the same time, the even distribution of the raw material allows the filter screen to filter out impurities more effectively, because the filter screen in each area can make full use of its filtration area, improving the overall filtration efficiency and reducing the filtration time required.

[0014] 2. After initial filtration, the raw material falls to the bottom of the shell and then undergoes secondary filtration through the filter cartridge to remove fine impurities, thereby improving the purity of the raw material. The dual filtration system can more effectively remove impurities from the raw material, including solid particles and suspended matter, thus improving the purity of the raw material. High-purity raw materials help ensure the smooth progress of subsequent chemical reactions and improve the quality and consistency of the product. Attached Figure Description
