Abstract
Description
Technical Field
[0001] This application relates to the field of airflow pulverizer technology, and more particularly to a nanoscale airflow pulverizer for advanced abrasives. Background Technology
[0002] An air jet mill is a device that uses high-speed airflow or hot steam energy to pulverize materials. It generates a high-speed airflow by compressing air or hot steam, causing material particles to collide, rub against each other, or impact and shear against the equipment components, thereby achieving pulverization. Air jet mills are widely used in industrial fields, especially in the field of ultrafine pulverization, and are characterized by high efficiency and uniformity.
[0003] However, existing high-grade abrasive nano-level air jet mills require high purity of raw materials to avoid impurities affecting the quality of subsequent processing. In addition, the impeller needs to be cleaned, maintained, and replaced regularly to avoid affecting its utilization rate. Utility Model Content
[0004] In view of the above problems, this application provides a nano-level airflow pulverizer for advanced abrasives to solve the problems of existing nano-level airflow pulverizers for advanced abrasives. Since the pulverizer is used to pulverize raw materials, it is necessary to improve the purity of the raw materials during pulverization to avoid impurities in the raw materials affecting the quality of subsequent pulverization processing. At the same time, the impeller also needs to be cleaned, maintained and replaced regularly during long-term use of the pulverizer to avoid affecting the utilization rate of the impeller.
[0005] This application provides a nanoscale airflow pulverizer for advanced abrasives. It includes a pulverizer body, an impeller body mounted on the inner wall of the pulverizer body, the impeller body mounted on the discharge port side, the discharge port being located on the outer wall of the pulverizer body, a mounting groove at the top of the discharge port, a cover plate movably fitted inside the mounting groove, a rotating shaft mounted at the center of the top of the cover plate, a first bevel gear fixedly mounted at the bottom of the rotating shaft, a second bevel gear meshing with the outer wall of the first bevel gear on all four sides, a screw fixedly mounted on one side of the second bevel gear, a threaded block meshing with the outer wall of the screw, a support plate fixedly mounted at the bottom of the threaded block, the threaded block movably fitted inside a groove located at the bottom of the cover plate.
[0006] With the above solution, after the cover plate is movably embedded into the mounting groove, the rotating shaft is turned to drive the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear to rotate, which in turn drives the screw to rotate, causing the threaded block to move threadedly on the outer wall of the screw. At the same time, the threaded block slides in the groove, which in turn drives the support plate to move. The four support plates support the inner wall of the mounting groove, improving the firmness of the cover plate installation. The turning makes the installation more convenient and secure, and also makes disassembly more convenient. In this way, the impeller body can be easily cleaned, maintained, and disassembled, improving the crushing efficiency of the crusher body.
[0007] In some embodiments, a limiting groove is formed at the top of the main body of the crusher, a telescopic spring is fixedly installed at the bottom of the inner wall of the limiting groove, a sealing ring is fixedly installed at the top of the telescopic spring, and the bottom of the sealing ring is sleeved inside the limiting groove.
[0008] With the above solution, after the cover plate is fully inserted into the top of the crusher body, it will push the sealing ring, causing the sealing ring to slide into the limiting groove. This will also cause the telescopic spring to contract. Through the telescopic spring, the sealing ring can better fit the bottom of the cover plate, thus improving the sealing effect of the sealing ring.
[0009] In some embodiments, an air inlet is installed on the outer wall of the crusher body, and a feed pipe is installed on the other side of the outer wall of the crusher body, with the other side of the feed pipe installed on one side of the bottom of the feed trough.
[0010] The above method allows the filtered raw materials in the feed trough to be introduced into the main body of the crusher through the feed pipe, and gas to be introduced into the main body of the crusher through the air inlet, thereby performing airflow crushing of the raw materials in the main body of the crusher.
[0011] In some embodiments, an installation frame is movably sleeved on the inner wall of the feed trough, and a filter screen is fixedly installed on the inner wall of the installation frame.
[0012] The above method involves feeding the raw materials into the feed trough, where they fall onto a filter screen. The filter screen then filters out impurities from the raw materials, improving their purity and preventing any impact on the quality of subsequent processing.
[0013] In some embodiments, a first motor is installed on one side of the feed trough, a threaded rod is fixedly installed on one side of the first motor, a connecting block is threaded to the outer wall of the threaded rod, a T-shaped rod is fixedly installed at the bottom end of the connecting block, a scraper is fixedly installed at the bottom end of the T-shaped rod, and discharge ports are opened on both sides of the feed trough.
[0014] The above method involves feeding the raw materials into the feed trough, where they fall onto the filter screen for filtration. The first motor rotates the threaded rod, causing the connecting block to move left and right on the outer wall of the threaded rod. This movement, in turn, moves the T-shaped rod and scraper left and right, pushing the raw materials through the scraper. This allows for rapid filtration on the filter screen, while unfilterable impurities are discharged from the discharge port by the scraper, preventing any impact on the filter screen's filtration efficiency.
[0015] In some embodiments, a collection trough is fixedly installed on the outer wall of the feed trough, and the collection trough is located at the bottom of the discharge port.
[0016] With the above method, when the scraper is moved left and right, it also plays a cleaning role, collecting the impurities that cannot be filtered through the collection tank, which facilitates subsequent processing.
[0017] In some embodiments, a connecting rod is fixedly installed on the inner wall of the feed trough, the connecting block is movably sleeved on the outer wall of the connecting rod, and the connecting rod is located at the bottom end of the threaded rod.
[0018] With the above scheme, when the connecting block moves left and right on the outer wall of the threaded rod, it also slides left and right on the outer wall of the connecting rod. The connecting rod acts as a limit to prevent the connecting block from rotating synchronously with the connecting rod.
[0019] The beneficial effects of this utility model are as follows: 1. By turning the shaft, the first bevel gear meshes with and drives the second bevel gear to rotate. This causes the threaded block to move along the outer wall of the screw, while simultaneously sliding in the groove. This, in turn, moves the support plate. The four support plates support the inner wall of the mounting groove, improving the stability of the cover plate installation. Tightening makes installation more convenient and secure, and also makes disassembly easier. This allows for convenient cleaning, maintenance, and disassembly of the impeller body, improving the crushing efficiency of the crusher.
[0020] 2. After the raw material is introduced into the feed trough, it falls onto the filter screen and is filtered by the filter screen. The first motor is operated to drive the threaded rod to rotate, causing the connecting block to move left and right on the outer wall of the threaded rod. Then, the T-shaped rod and scraper move left and right. The scraper moves left and right to push the raw material, so that the raw material can be filtered quickly on the filter screen. Impurities that cannot be filtered can be discharged from the discharge port by the push of the scraper, so as not to affect the filtration efficiency of the filter screen.

The first motor 21 is operated to drive the threaded rod 22 to rotate, so that the connecting block 23 moves left and right on the outer wall of the threaded rod 22. Then, it drives the T-shaped rod 24 and the scraper 25 to move left and right. The scraper 25 moves left and right to push the raw material, so that the raw material can be filtered quickly on the filter screen 20.
