Abstract

[0002] In the process of large particle salt production, multi-stage screening devices are widely used to screen large particle salt. In chemistry, salt refers to a compound formed by the combination of a metal ion or ammonium ion and an acid radical ion through an ionic bond. When dissolved in water, all ions will dissociate. Double salts can usually be prepared by mixing saturated solutions of these two salts and crystallizing. They are widely present in nature. For example, alum is a natural and widely used double salt. Multi-stage screening devices are also used in the process of large particle salt production.
[0003] At present, in the process of large particle salt production, a multi-stage screening device is needed to screen large particle salt for the convenience of large particle salt production. However, the existing multi-stage screening device drives the screen to vibrate through a vibration motor for screening. In actual use, there are often some small particles mixed in the larger salt particles, resulting in poor screening quality. Summary of the Utility Model

[0030] Refer to Figures 1-3, an embodiment provided by the utility model: a multi-stage screening device for large particle salt production, including a base 1. At the four corners of the top of the base 1, second motors 14 are fixedly connected. The output ends of the second motors 14 are fixedly connected with eccentric wheels 15. A fixing plate 13 is fixedly connected between two adjacent eccentric wheels 15 in the front and back. At the top of the two fixing plates 13, support plates 4 are fixedly connected. At the top of the right support plate 4, a first side plate 17 is fixedly connected. At the right end of the first side plate 17, a first motor 7 is fixedly connected. The output end of the first motor 7 penetrates through the screening cylinder 2 and is fixedly connected with a transmission rod 8.

A vibration motor 16 is arranged between two adjacent conical bins 6.
[0031] During screening, the holes in the left screening mesh 10 are the smallest, which can screen out smaller particle salts. The holes in the middle screening mesh 10 are slightly larger, and then the holes in the right screening mesh 10 are even larger to conduct multi-stage screening.
[0032] Through the top of the outer diameter of the screening cylinder 2, a feed bin 5 is fixedly connected. Through the bottom of the conical bin 6, a discharge pipe 11 is fixedly connected.

The screened particles will enter the conical bin 6 for collection, and only need to open the plug valve 12 to conduct blanking and collection.
[0034] Working principle: When using the multi-stage screening device, first, large particle salts enter the inside of the screening cylinder 2 from the feed bin 5, and the screening cylinder 2 remains in an inclined state. Then, start the first motor 7 to work, driving the stirring rod 9 to rotate to turn the salts in the screening cylinder 2. Then, the screening meshes 10 increase in holes from left to right to screen out salts of different particle sizes. At the same time, the vibration motor 16 assists in the work. The second motor 14 below works to drive the eccentric wheel 15 to rotate, driving the device to float for screening work, improving the screening effect. The screened particles will enter the conical bin 6 for collection, and only need to open the plug valve 12 to conduct blanking and collection.
