Description

Technical Field

[0001] The invention relates to the technical field of dust removal and separation, and more specifically to a screening and dust removal device for producing particle catalysts. Background Art

[0002] A catalyst generally refers to a substance that increases the reaction rate without changing the total standard Gibbs free energy of the reaction. It can also be described as a substance that can increase the reaction rate without changing the chemical equilibrium in a chemical reaction, and whose quality and chemical properties do not change before and after the chemical reaction. According to statistics, more than 90% of industrial processes use catalysts, such as chemical, petrochemical, biochemical, environmental protection, etc.

[0003] Catalyst particle size is the size of the catalyst particles. The catalyst has different shapes and can be expressed in different ways. Catalyst particle size is the size of the catalyst particles. The catalyst has different shapes and can be expressed in different ways. The particle size of a pellet catalyst is expressed by its diameter.

[0004] The existing technology is to remove dust by simple vibration. This dust removal method removes surface dust by vibration. However, we know that the density of dust is relatively small and it is difficult to remove it by vibration alone. Therefore, negative pressure suction equipment is often used to absorb impurities. However, strong negative pressure suction operation can easily cause granular catalysts to block the suction channels, affecting the effect of absorbing impurities. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a particle catalyst production screening and cleaning equipment. This scheme separates the cleaning equipment plate and the vibrating screen through a track isolation net. The suction pipe cooperates with the suction branches to absorb impurities, so that the catalyst particles spread on the vibrating screen can quickly absorb impurities. The track isolation net prevents the catalyst particles from clogging the suction branches due to negative pressure, thereby avoiding affecting the impurity removal effect. The moving track isolation net also prevents the catalyst particles from being adsorbed on the track isolation net. According to the moving direction of the cleaning equipment plate, the vibrating pads are selectively allowed to contact the surface of the vibrating screen. The vibrating pads drive the vibration of the impurity absorption area of ​​the vibrating screen, drive the catalyst particles to move, realize the vibration out of the dust, and improve the impurity absorption effect. At the same time, the vibration effect can also clean the mesh of the vibrating screen, thereby improving the screening and impurity removal quality of the equipment.

[0010] Furthermore, a residual material box and a finished product box are placed at the bottom of the equipment machine tool, the residual material box is arranged vertically corresponding to the vibrating screen, and the finished product box is arranged vertically corresponding to the front side of the vibrating screen. A flip shaft is fixedly connected to the center line of the bottom of the vibrating screen, and a flip motor is fixedly connected to one side of the equipment machine tool, and the output end of the flip motor is fixedly connected to the flip shaft. During the operation of the vibrating screen, the defective catalyst particles are screened and fall into the residual material box, which is convenient for the centralized processing of the defective catalyst particles. The flip motor is used to drive the flip shaft to rotate to realize the flipping of the vibrating screen. After the impurity removal process is completed, the vibrating screen flips to pour the catalyst particles into the finished product box, thereby improving the efficiency of removing impurities.

[0011] Furthermore, the tops of both ends of the equipment machine tool are fixedly connected with lifting electric rails, and the middle part of the support beam is fixedly connected to the output end of the lifting electric rails. The support beam is raised and lowered by the lifting electric rails to slightly adjust the height of the cleaning equipment plate to meet the impurity removal needs of catalyst particles of different particle sizes. The cleaning equipment plate is adjusted to the highest position to facilitate the flipping of the vibrating screen.
