Description

Technical Field

[0001] The invention relates to the technical field of ceramic pulverization, in particular to a pulverizer for composite ceramic materials. Background Art

[0002] A pulverizer is a machine that crushes large solid materials into the desired size. Depending on the size of the material being crushed or processed, pulverizers can be categorized as coarse crushers, pulverizers, and ultrafine pulverizers. The forces applied to solids during the pulverization process include shearing, impact, crushing, and grinding.

[0003] Patent announcement number CN216125810U relates to a composite ceramic pulverizer, comprising a pulverizer cover, a feed port, a discharge port, a filter plate, a support column, and a pulverizer body. The support column is provided at the bottom end of the pulverizer body, and the filter plate is provided within the pulverizer body. The filter plate divides the interior of the pulverizer body into a coarse crushing chamber and a fine crushing chamber. The coarse crushing chamber is located at the top of the filter plate, and the coarse crushing chamber is located at the bottom of the filter plate. The pulverizer cover is fixedly connected to the top of the pulverizer body. A power motor is provided in the inner center of the pulverizer cover, and the power motor is connected to the coarse crushing device. The coarse crushing device consists of a roller and a crushing hammer fixed to the roller. This patent allows for multiple crushing of items, reducing the time required to replace machinery and staff, enhancing the process of crushing and screening items, and reducing the hassle of subsequent work.

[0004] In the above patent, multiple crushing of raw materials is achieved, the time for replacing machinery and staff is reduced, and the process of crushing and screening of items is strengthened. However, most of the existing crushers have the functions of reducing the replacement of machinery and crushing and screening of raw materials, but do not solve the problem that the feed port may be blocked when too much material is fed at one time. At the same time, the volume of raw materials is different. When the processed raw materials are too large, directly processing raw materials with too large a volume will increase the wear of the crushing wheel, which increases the frequency of replacement and maintenance of the crushing wheel. Summary of the Invention

The rotating shaft is driven to rotate when the dredging block moves up and down by the threaded connection between the rotating shaft and the dredging block, thereby cleaning the screen.

[0015] The present invention provides a pulverizer for composite ceramic materials. It has the following beneficial effects:

[0016] (1) This invention raises the lifting plate by contacting the rotating block with the lifting plate. The lifting plate raises the straight rod, which raises the straight rod and contacts the cross rod. The cross rod moves toward the feed port, and the cross rod drives the L-shaped plate to move. The movement of the L-shaped plate causes the triangular protrusions on the L-shaped plate to rough-process the raw materials, process the raw materials that are too large, and prevent the raw materials that are too large from entering the crushing box and causing the wear of the crushing wheel to increase. At the same time, the movement of the L-shaped plate drives the rack to move, thereby rotating the rotating shaft. The rotation of the rotating shaft drives the rotating plate to rotate, moving the raw materials in the feed port, and preventing the raw materials from accumulating in the feed port and causing the feed port to be blocked. When the rotating block separates from the lifting plate, the rotating plate rotates downward, thereby achieving intermittent feeding.

[0017] (2) This invention makes the pressing plate descend by bringing the rotating block into contact with the pressing plate, which drives the pressing rod down, which drives the mounting plate down, and the pressing rod down brings the trapezoidal block into contact with the fixed block. The pressing rod continues to descend so that the trapezoidal block and the fixed block are squeezed, causing the slider to move. The movement of the slider drives the pressing rod to move, which drives the mounting plate to move, thereby cleaning the defective products on the surface of the screen through the triangular rod, preventing the defective products from accumulating on the screen so that the products that have been processed subsequently cannot pass through the screen. At the same time, the inclined surface of the mounting plate contacts the short plate, causing the short plate to rotate, and the defective products in the discharge trough are cleaned by the rotation of the short plate, preventing the defective products from accumulating in the discharge port and affecting the cleaning of the defective products.

[0018] (3) This invention lowers the lifting rod by pressing the plate, which drives the connecting plate down. The connecting plate lowers the dredging block, which causes the rotating shaft connected to the dredging block to rotate. The rotation of the rotating shaft drives the rolling rod to rotate, so that the bottom of the screen is cleaned by the brush on the rolling rod to prevent dust from accumulating at the bottom of the screen. The bumps on the rolling rod collide with the screen, thereby shaking off the raw materials stuck in the screen, cleaning the mesh of the screen, and preventing the mesh from being clogged and causing the product to accumulate on the top of the screen.
