Description

Technical Field

[0001] This utility model relates to the technical field of grading and screening for bentonite production, specifically a grading and screening device for bentonite production. Background Technology

[0002] Bentonite is a non-metallic mineral with montmorillonite as its main mineral component. It possesses good ion exchange properties and is also known as "universal clay." Bentonite production is enormous, and demand is increasing daily. Screening utilizes a sieve to allow fine particles smaller than the sieve openings to pass through the sieve surface, while coarse particles larger than the sieve openings remain on the sieve surface, thus completing the separation of coarse and fine materials. This separation process can be viewed as consisting of two stages: material stratification and fine particle screening. Material stratification is a condition for separation, while proper screening of fine particles is the goal of separation. Screening is necessary in the production of bentonite. Existing bentonite grading and screening methods are time-consuming and labor-intensive, affecting production efficiency and bentonite yield. Therefore, there is an urgent need for a grading and screening device for bentonite production.

[0003] Currently, existing grading and screening devices for bentonite production cannot clean impurities and dirt from the screens, reducing the screen's permeability and filtration efficiency, and increasing screen clogging. Furthermore, the existing grading and screening devices for bentonite production have poor uniformity and flowability of bentonite materials during the screening process, making it difficult to perform screening effectively. Utility Model Content

[0004] The purpose of this utility model is to provide a grading and screening device for bentonite production, in order to solve the problems mentioned in the background art, namely, that the existing grading and screening devices for bentonite production cannot clean the impurities and dirt on the screen, which reduces the air permeability and filtration effect of the screen and increases the phenomenon of screen blockage. In addition, the existing grading and screening devices for bentonite production have poor uniformity and flowability of bentonite materials during the screening process, which makes it inconvenient to perform screening better.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grading and screening device for bentonite production, comprising a chassis, a rear housing on one side of the chassis, the rear housing being fixed to the chassis by hexagonal bolts, a servo motor adapted to the rear housing being installed on the inner wall of the rear housing, the output end of the servo motor being connected to the input end of a reducer, the output shaft of the reducer being connected to a rotating gear adapted to the reducer, the rotating gears being symmetrically distributed, another rotating gear being fixed to the rear housing by a fixing rod, one rotating gear being fixed to the other rotating gear by a chain adapted to the chain, a movable locking block adapted to the chain being installed on one side of the chain, the movable locking block being fixed to the chain by a fastening nut, and a cleaning brush being installed at the bottom of the movable locking block.

[0007] Preferably, a side housing is provided on the other side of the chassis, and a slide rail is provided on the top of the support cross plate. The slide rail is connected and fixed to the side housing through a connecting port. An eccentric shaft adapted to it is slidably connected to the inner wall of the slide rail. A semi-circular block is provided below the connecting port. The eccentric shaft is located on the top of the semi-circular block. The inner wall of the eccentric shaft is connected to the outer wall of one end of a transmission shaft adapted to it through the semi-circular block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This grading and screening device for bentonite production operates through a servo motor and reducer, which drives the rotating gears and chains to rotate at a constant speed. This allows the cleaning brush to rotate cyclically, thereby cleaning impurities and dirt on the coarse and fine screens, maintaining the air permeability and filtration effect of the screens, reducing screen clogging, and ensuring long-term stable operation. The coarse and fine screens can separate bentonite particles into different particle sizes to meet the needs of different industries. The vibrator causes the material to bounce on the screen, naturally stratifying according to particle size and falling through the corresponding screen holes.

[0014] 2. This grading and screening device for bentonite production uses a drive motor in conjunction with a small gear to drive a large gear that connects the transmission shaft and the eccentric shaft. This allows the coarse and fine filter screens to move back and forth, ensuring the uniformity and flowability of the bentonite material for better screening. The separated material is collected centrally through the inclined feed inlet for subsequent processing. Different screen sizes can be replaced through the door, and selecting a suitable screen can significantly improve screening efficiency. Attached Figure Description
