Description

Technical Field

[0001] The utility model relates to the technical field of tungsten slag crushing devices, and particularly relates to a crushing device for tungsten slag recovery. Background Technique

[0002] Tungsten slag is a solid waste discharged during the production of WO3 or ammonium paratungstate using wolframite or scheelite as the main raw material. The traditional process for producing WO3 is the soda sintering process; the soda sintering process has a low metal recovery rate, poor product quality, and serious environmental pollution, so the alkali pressure leaching process was later adopted; the tungsten slag discharged by the alkali pressure leaching process exists in the form of hydroxides, but its composition is basically the same as that of the soda sintering process; for every 1t of WO3 produced, about 0.5t of tungsten slag is discharged; during the recovery process, the tungsten slag needs to be crushed.

[0003] For example, the patent with the national authorized patent publication number CN210613859U discloses a crushing device for tungsten slag recovery, including a device housing and a feed box. Reinforcing plates are fixedly arranged on the side edges of the top and bottom of the feed box. A feed hopper is fixedly arranged at the bottom of the feed box, and the bottom of the feed hopper is fixedly connected to the inlet in the middle of the top of the device cover. Fixed top plates are fixedly arranged on the front and back of the device cover, and the bottom of the device cover is fixedly connected to the top of the device housing. Fixed bottom plates are fixedly arranged at the bottom of the front and back of the device housing. The crushing device for tungsten slag recovery of the present utility model, through the fixedly installed hydraulic cylinder, facilitates the separation of the device housing and the device cover to maintain and clean the inside of the crushing device, avoids serious wear of internal components, improves the crushing efficiency and extends the service life of the device; through the fixedly arranged reinforcing plates and support plates, it is convenient to strengthen and protect the feed box, and avoid accidents from causing injuries to workers.

[0004] However, in the above-mentioned crushing device for tungsten slag recovery, during the process of crushing tungsten slag, it cannot enable workers to perform appropriate crushing adjustment according to the required size of tungsten slag. If the size of tungsten slag cannot be properly controlled, it will cause fluctuations in product quality, which is not conducive to subsequent processing and utilization, and will make the finally obtained tungsten slag product unable to meet the specifications of subsequent processes, which will affect the extraction efficiency of tungsten and the quality of the final product.
