The utility model belongs to the field of ethylene glycol storage, specifically is a kind of ethylene glycol storage device with moisture-proof function, including jar body, the outer wall of jar body is fixedly connected with supporting leg, the top of jar body is provided with liquid inlet valve, the outer wall of jar body is provided with liquid outlet valve, the top of jar body inner wall is fixedly connected with electric telescopic handle, the output of electric telescopic handle is fixedly connected with extrusion plate, two gas outlets are opened symmetrically in the inside of extrusion plate, one-way valve is arranged in the inside of two gas outlets;The utility model provides a kind of ethylene glycol storage device with moisture-proof function, by the cooperation of spring and stop block, when stopping injecting ethylene glycol, extrusion plate is sealed, make ethylene glycol be stored in the below of extrusion plate, by electric telescopic handle control extrusion plate move downwards, under the extrusion of extrusion plate, make the air above ethylene glycol be extruded along one-way valve, thus make ethylene glycol separate from the air in jar body, avoid the air in jar body humidification influence the purity of ethylene glycol.

This utility model discloses an automatic separation and collection device for heavy debris in an airflow conveying system, relating to the technical field of airflow separation equipment. The separation body includes a cylindrical cavity with a conical guide hood at the top. A spiral feed plate is located between the outer side of the guide hood and the inner wall of the cavity. A feed pipe is located on one side of the upper part of the cavity, a discharge pipe is located at the top of the cavity, and a discharge port is located at the bottom of the cavity. Corn fibers, being lightweight and highly susceptible to airflow, move upwards more easily with the airflow, while heavy debris, due to gravity and centrifugal force, tends to sink closer to the inner wall of the cavity, significantly improving the initial separation efficiency and reducing the mutual entanglement of corn fibers and heavy debris.

The application relates to a filtering device for a mother liquor recovery reaction kettle, which comprises a tank body, the tank body is arranged at the top of the mother liquor recovery reaction kettle, a filter cartridge is rotatably arranged in the tank body, a rotating part is arranged on the tank body, a water inlet pipe is arranged on the peripheral wall of the tank body, a connecting pipe is arranged at the bottom of the tank body, a cleaning brush is arranged in the tank body, and the bristles of the cleaning brush are attached to the outer peripheral wall of the filter cartridge; water enters the tank body through the water inlet pipe, is filtered by the filter cartridge in the tank body, and is then conveyed into the reaction kettle through the connecting pipe; the rotating part drives the filter cartridge to rotate; the bristles of the cleaning brush are attached to the outer peripheral wall of the filter cartridge; the outer peripheral wall of the filter cartridge can be cleaned when the filter cartridge rotates, so that the filter cartridge is prevented from being blocked, and the filtering effect of the filter cartridge is good.

This utility model discloses a raw material purification and conveying device for 3,5-dibromo-o-aminobenzaldehyde, relating to the field of organic chemical production technology. The utility model includes a conveying tank, a top cover, a fixing ring, and a cleaning tank. A top cover is fixed to the top of the conveying tank, and a fixing ring is fixed to the center of the top of the top cover. Dispersion tubes are fixed in a circular array at the bottom of the fixing ring, passing through and fixed inside the top cover. Each dispersion tube has a dispersion chamber fixedly connected to its bottom end. A conveying pipe is fixedly connected to the upper periphery of the conveying tank, and the conveying pipe is L-shaped. A cleaning tank is fixed to the periphery of the conveying pipe. This utility model, by setting up a conveying tank, a top cover, a fixing ring, and a cleaning tank, solves the problem that the alkaline washing of the 3,5-dibromo-o-aminobenzaldehyde raw material is often insufficient, and that neutralization after alkaline washing affects the purity of the o-aminobenzaldehyde production.

The utility model provides a kind of casting device of extrusion equipment for film processing, including rack and extrusion die, still including cooling forming assembly, guide assembly, scraping assembly collection assembly and cleaning component, the utility model cooperates between scraping assembly, when cooling roll works, by driving cylinder and moves support and tool holder forward, so that scraper is in contact on cooling roll, so that the raw material on the surface of cooling roll is scraped, so as to ensure the cooling effect of raw material, also avoid because raw material residue leads to uneven film, so effectively increase the final quality of film, also by setting cleaning component, by driving cylinder one drives cleaning roller and cooling roll contact, the glue layer on the surface of cleaning roller, so that the dust on the surface of cooling roll is collected, so as to avoid when cooling film, the dust enters film inside, affect the purity and quality of film, effectively improve the quality of final product film.
