Description

Technical Field

[0001] The utility model belongs to the technical field of chemical material processing, in particular to a dust removal and screening device for chemical material processing. Background Art

[0002] Nowadays, the chemical industry level of countries around the world is getting higher and higher, and more and more chemical materials are used. Some of them are relatively hard and need to be crushed and screened before they can be used.

[0003] Existing chemical production and processing machines require that harder chemical materials be crushed using a crusher first, and then screened using a screening machine. This results in the need to purchase different machines to crush and screen geologically hard chemical materials, significantly increasing costs. Furthermore, some geologically hard chemical materials tend to be covered with a lot of dust, which easily disperses during machine operation, affecting the work environment. We propose a dust removal and screening device for chemical material processing. Utility Model Content

[0004] The purpose of the utility model is to provide a dust removal and screening device for chemical material processing to solve the problems raised in the above background technology.

[0011] In this technical solution, when in use, the staff first puts the chemical materials that need to be crushed and screened into the shell, and then inserts the sealing cover on the top of the shell. Then, through the provided power assembly, the power assembly drives the two crushing rollers and the elliptical plate to rotate. At this time, the continuous rotation of the elliptical plate will drive one end of the screening plate to repeatedly rotate up and down;

[0012] Subsequently, the driving assembly is provided to drive the two baffles away from each other, and the chemical materials on the top of the two baffles will fall downward. When the chemical materials pass through the two crushing rollers, the two crushing rollers will crush the chemical materials, so that the particularly large chemical materials are crushed. Subsequently, the crushed chemical materials will fall to the top of the screening plate. The screening plate will repeatedly rotate up and down to screen the chemical materials. Subsequently, smaller chemical materials will leak from the screening plate and fall into the collection box 2 for collection, and larger ones will move downward under the action of gravity and roll into the collection box 1 for collection, thereby being able to classify chemical materials of two volumes.

[0013] After the screening is completed, the exhaust fan can be started. The exhaust fan will extract the dust in the outer shell through the U-shaped pipe and the two air inlet pipes.

[0085] Working principle: When in use, the staff first puts the chemical materials that need to be crushed and screened into the shell 1, and then inserts the sealing cover 3 on the top of the shell 1. Then, the motor 10 is started first. The output shaft of the motor 10 will drive one of the transmission wheels 13 to rotate, and then one of the transmission wheels 13 will drive the belt 11 to drive, and the belt 11 will drive the other transmission wheel 13 to rotate. Then, the two transmission wheels 13 will respectively drive the two crushing rollers 17 to rotate, and then one of the crushing rollers 17 will drive one of the transmission wheels 2 28 to rotate, and one of the transmission wheels 2 28 will drive the belt 2 27 to drive, and the belt 2 27 will drive the other transmission wheel 2 28 to rotate, and then the other transmission wheel 2 28 will drive the elliptical plate 23 to rotate. At this time, the continuous rotation of the elliptical plate 23 will drive one end of the screening plate 19 to repeatedly rotate up and down;

[0086] Then, the motor 14 can be started, and the output shaft of the motor 14 will drive the bidirectional threaded rod 24 to rotate. Under the action of the thread, the bidirectional threaded rod 24 will drive the two connecting blocks 25 to move away from each other, and the two connecting blocks 25 will respectively drive the two baffles 21 to move away from each other. Then, the chemical materials on the top of the two baffles 21 will fall downward. When the chemical materials pass through the two crushing rollers 17, the two crushing rollers 17 will crush the chemical materials, so that particularly large chemical materials are crushed. Then, the crushed chemical materials will fall to the top of the screening plate 19, and the screening plate 19 will be moved to the top of the screening plate 19. 9 repeatedly rotates up and down to screen the chemical materials. Under the action of the rubber plate 18, when the screening plate 19 squeezes the rubber plate 18, the rubber plate 18 can be deformed, so that the rotation range of the screening plate 19 is small and the chemical materials can be prevented from falling through the gap between the screening plate 19 and the inner wall of the shell 1. As a result, smaller chemical materials will leak from the screening plate 19 and fall into the collection box 2 7 for collection, while larger ones will move downward under the action of gravity and roll into the collection box 1 6 for collection, thereby being able to classify chemical materials of two volumes;

[0087] After the screening is completed, the exhaust fan 15 can be started. The exhaust fan 15 will extract the dust in the outer shell 1 through the U-shaped pipe 16 and the two air inlet pipes 22. Then, the outside air will enter the outer shell 1 through the dustproof net 5 in the several through holes 4. Then, the air accompanied by dust will enter the two air inlet pipes 22, and the air with dust in the two air inlet pipes 22 will enter the U-shaped pipe 16. Then, the exhaust fan 15 will transport the air with dust in the U-shaped pipe 16 to the water storage box 8. Clean water is placed in the water storage box 8. When dust comes into contact with water, the water can adsorb the dust. Then, the air will be discharged to the outside through the filter 9 to prevent dust from being discharged to the outside. After the dust in the outer shell 1 is cleaned, the valve on the drain pipe can be opened to drain the water in the water storage box 8 and replace it.

[0088] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.
