Particulate matter screening device used for salt manufacturing equipment and screening method of particulate matter screening device

Abstract

The invention discloses a particulate matter screening device used for salt manufacturing equipment. The particulate matter screening device comprises a truss, a fixed box is installed at the top of the truss, an air bellow is installed on one side of the fixed box, a driving motor is installed at one end of the fixed box, one end of the driving motor is connected with a reverser, a screening roller is arranged on the inner side of the fixed box, multiple sets of first screens are installed on the outer side of the screening roller at equal intervals, and a blocking strip is installed on the side, close to the first screens, of the outer side of the screening roller. A feeding barrel is installed on one side in the truss, a screening groove is formed in the screening roller, a screening inner barrel is arranged in the screening groove, multiple sets of second screens are mounted on the outer side of the screening inner barrel at equal intervals, and vibration motors are connected between the two sides of the screening groove and the inner walls of the two sides of the screening roller. The particulate matter screening device can well screen salt particulate matter, can keep salt particles dry, avoids adhesion and meanwhile is suitable for screening treatment of water-soluble fertilizer and wide in application range.

Description

technical field [0001] The invention belongs to the field of screening devices, and in particular relates to a salt particle screening device, more specifically, a particle screening device and a screening method for salt making equipment. Background technique [0002] During the preparation of salt particles, in order to obtain smoke with a specified particle size, it is necessary to use a sieving device to screen the salt particles, separate the large salt particles from the small particle salt, and collect the small particle salt uniformly. At the same time, it is convenient to refine the salt with large particles. [0003] The existing particle screening devices for salt making equipment have certain disadvantages in use. The existing particle screening devices for salt making equipment basically use one-time screening during screening, and the screening effect is average. ; The existing particle screening device for salt making equipment is affected by the environment ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a particle screening device for salt making equipment, which can effectively solve the problem that the existing particle screening devices for salt making equipment basically have One-time screening is used, and the screening effect is general; the existing particle screening device used for salt making equipment is affected by the environment when screening salt particles, and the salt particles are prone to sticking, which affects the screening; the existing The particle screening device used in salt making equipment has a small scope of application and cannot meet the technical problems of screening other state substances or other particles
