Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, in particular to a shaking screen type cryolite impurity remover. Background Art

[0002] Cryolite is a mineral whose main component is sodium hexafluoroaluminate or sodium aluminum fluoride. It is used as a flux in the electrolytic aluminum industry and as a sunscreen for making milky white glass and enamel. Currently, cryolite is mostly in powder form. After production is completed, cryolite needs to be screened to remove large particles of impurities in it to avoid affecting the quality of the product.

[0003] A shaking screen machine is a vibrating screening device, which can be used as a screening device for cryolite during the processing of cryolite. When screening cryolite, the shaking screen machine directly pours the cryolite onto the screen, and the cryolite falls down under the vibration of the machine body, while large particles of impurities are retained on the screen, making it convenient to screen cryolite through this device. However, during the screening process, some large particles of impurities will be blocked on the mesh of the screen, which will affect the screening efficiency. The current screen is fixedly installed on the shaking screen machine, and the blocked mesh can only be cleaned by manually leaning into the screen. Not only is the cleaning inconvenient, but the operation is also dangerous. In view of this, we propose a shaking screen type cryolite impurity remover. Utility Model Content

A vibration motor 17 is installed at the bottom of the box body 14.

[0031] In this embodiment, the cutter of the sieve plate 15 is equipped with a discharge bin 151, and the discharge bin 151 is wide at the rear end and narrow at the front end. This design is conducive to the screened impurities to gather at the discharge bin 151, which is convenient for discharge through the discharge bin 151 and convenient for collection.

[0032] In this embodiment, the sieve plate 15, the connecting plate 152, the insert plate 153 and the discharge bin 151 are an integrated structure, and the sieve plate 15, the connecting plate 152, the insert plate 153 and the discharge bin 151 are all made of stainless steel.

Then the user pours the cryolite powder onto the sieve plate 15, and the box 14 drives the sieve plate 15 to vibrate. At this time, the cryolite powder falls through multiple meshes, and large particles of impurities are trapped on the top of the sieve plate 15. The screened cryolite powder falls into the receiving trough 111 through the discharge port 142 and is discharged;

[0039] When the sieve plate 15 needs to be removed, the user first pushes the push plates 165 on both sides upwards, and the push plates 165 push the fixing rod 163 to move upwards, and the fixing rod 163 drives the slider 162 to move upwards. The second spring 164 is compressed by the slider 162 at the same time.
