Description

Technical Field

[0001] The utility model relates to the technical field of xanthate production devices, in particular to a pneumatic alkali adding device for xanthate production. Background Art

[0002] Xanthate is a commonly used collector for sulfide ore re-selection. Its scientific name is hydroxyxanthate, which is divided into ethyl xanthate, butyl xanthate, isopropyl xanthate, isobutyl xanthate, amyl xanthate, etc. It is yellow crystal or powder. The existing xanthate production process in China is mostly the traditional kneading process, using alcohols, carbon disulfide and caustic soda as raw materials. The production process is simple. During the production process, the flake caustic soda is ground into powder, and then the caustic soda powder is added to the reactor and reacts with alcohol and carbon disulfide to finally produce solid powdered xanthate.

[0003] Usually caustic soda powder is added directly into the reactor. However, due to its strong hygroscopicity, caustic soda easily absorbs moisture and agglomerates in the air, which makes adding difficult. Sometimes manual stirring is required. However, caustic soda is highly corrosive and can corrode the skin and fibers. Manual adding may cause occupational injuries to operators, and manual adding may also result in inaccurate addition amounts, which may lead to high unit consumption of products or quality problems.

[0004] After searching, a pneumatic alkali-adding device for xanthate production with patent announcement number CN217663199U was found. Although the device can solve the technical problems existing in the prior art, after the caustic soda is fed into the alkali-adding tank, the caustic soda easily adheres to the inner wall of the tank during the alkali-adding process, which makes cleaning very troublesome. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a pneumatic alkali-adding device for xanthate production, which can effectively prevent caustic soda from adhering to the inner wall of a tank body and make it more convenient to clean the inner wall of the tank body.

Two groups of bolts are threaded on the U-shaped seat, and nuts are threaded on the two groups of bolts. The U-shaped seat is detachably sleeved on the left end of the fixing plate through the cooperation of the bolts and the bolt holes. A spring telescopic rod is fixedly installed on the left end of the U-shaped seat, and a strip scraper is fixedly connected to the left end of the spring telescopic rod. Two groups of guide grooves are symmetrically provided on the outer wall of the spring telescopic rod. A connecting rod is fixedly connected to the strip scraper, and a guide sleeve is fixedly connected to the connecting rod. The guide sleeve is slidably sleeved on the spring telescopic rod by cooperating with the guide groove, and a scraper strip is fixedly provided on the outside of the strip scraper.

[0008] Preferably, an observation window is provided at the front end of the reactor.

[0009] Preferably, the hopper upper cover is provided with a sealing cover, and the sealing cover is provided with a handle.

[0010] Preferably, a reinforcing rod is fixedly connected to the strip-shaped scraper.

[0011] Preferably, a sliding sleeve is fixedly provided on the inner wall of the guide sleeve.

[0012] Compared with the prior art, the utility model has the following beneficial effects: when in use, by starting the motor, the motor drives the drum to rotate through the transmission of the pulley and the transmission belt, and the drum drives the spiral blade to rotate to transport the added caustic soda into the reactor. When the drum rotates, the fixed plate is driven to rotate, so that the fixed plate drives the spring telescopic rod to rotate through the U-shaped seat, and the spring inside the spring telescopic rod is in a compressed state, so that under the action of the spring telescopic rod, the strip scraper is pressed against the inner wall of the alkali adding tank, and the strip scraper is driven to rotate during the rotation of the spring telescopic rod, so that the scraping strip on the strip scraper scrapes the inner wall of the alkali adding tank, and the guide sleeve and the connecting rod play a limiting role, which can prevent the strip scraper from rotating along the axial direction of the spring telescopic rod, so that when the drum rotates, the strip scraper can be kept in contact with the inner wall of the alkali adding tank, and the inner wall of the alkali adding tank can be scraped in an annular manner, thereby effectively preventing the caustic soda from adhering to the inner wall of the tank body, making it more convenient to clean the inner wall of the tank body.
