Description

Technical Field

[0001] This utility model relates to a ceramic ball testing ball milling device, belonging to the technical field of ball milling testing equipment. Background Technology

[0002] Ceramic balls possess properties such as wear resistance and high-temperature resistance, and are widely used in various fields, serving as catalysts, fillers, and abrasives. Currently, after the ceramic balls are manufactured, their wear resistance needs to be tested, and ball milling is an important method for verifying this performance. However, existing ceramic ball milling devices have several drawbacks: the cylinder is a one-piece structure, making manufacturing and maintenance cumbersome; the cylinder lacks a wear-resistant layer, leading to easy wear of the cylinder and cover plate, reducing service life; and the loading and unloading of ceramic balls is inconvenient, affecting testing efficiency. Utility Model Content

[0003] This invention provides a ceramic ball testing ball milling device to solve the problems mentioned in the background art.

[0004] This utility model relates to a ceramic ball testing ball milling device, including a support and a cylinder. The cylinder has an inlet and outlet in the middle, and a cover plate on the outside of the inlet and outlet. The cylinder is connected to a drive mechanism. A rotating shaft is fixed on the middle outer side of the two side covers and is rotatably mounted on the support. Removable cover plates are fixed at both ends of the cylinder. A polyurethane layer one is fixed on the inner wall of the cylinder, and a polyurethane layer two is fixed on the inner side wall of the cover plate. An annular boss is provided at the outer edge of the polyurethane layer two. An annular recess is provided at both ends of the polyurethane layer one to cooperate with the annular boss to form a labyrinth seal. The bottom of the cover plate has a mounting boss that extends into the inlet and outlet. A polyurethane block that cooperates with the inlet and outlet is inserted on the outside of the mounting boss. A fixing screw is fixed inside the polyurethane block. The upper end of the fixing screw passes through the cover plate and is connected to a locking nut. The bottom of the polyurethane block is flush with the inner wall of the polyurethane layer one. A quick-release mechanism is connected to the outside of the cover plate.

[0005] The quick-release mechanism includes a mounting base fixed to the outside of the inlet / outlet. A locking screw is rotatably mounted on the mounting base. The outer wall of the cover plate has an opening groove for the locking screw to rotate in and out. A clamping nut is provided on the locking screw. By using the locking screw that can rotate in and out of the opening groove, in conjunction with the clamping nut, the cover plate can be quickly fixed or separated from the inlet / outlet, making the operation simple and efficient.

[0006] A handle is fixed to the top of the cover plate, and a reinforcing rib is fixed to the outer wall of the closed cover. The other end of the reinforcing rib is fixed to the rotating shaft, which is rotatably mounted on the bracket via a bearing seat. The handle on the top of the cover plate facilitates the handling of the cover plate; the reinforcing rib on the outer wall of the closed cover enhances the structural strength of the connection between the closed cover and the rotating shaft, ensuring the stability of the cylinder during rotation and improving the reliability of the device operation.

[0007] The drive mechanism includes a driven pulley fixed to the outer wall of the cylinder, a driving pulley connected to the driven pulley via a belt, and a drive motor fixedly connected to the driving pulley. A base frame is fixed to the bottom of the support, and a fixed plate is fixed on the base frame. The drive motor is mounted on the fixed plate. The belt drive structure, consisting of the driven pulley, belt, driving pulley, and drive motor, can smoothly provide power for the rotation of the cylinder.

[0008] An adjusting seat plate is hinged to the top of one end of the fixed plate. The other end of the adjusting seat plate has an adjusting slot with an adjusting bolt inside. The bottom of the adjusting bolt is fixed to the fixed plate. Adjusting nuts are located on the adjusting bolts above and below the adjusting slot. By utilizing the hinged adjusting seat plate and the coordination of the adjusting slot, adjusting bolt, and adjusting nut, the position of the drive pulley can be easily and finely adjusted, thereby flexibly adjusting the belt tension and preventing a decrease in transmission efficiency due to belt loosening after long-term use, ensuring the stability of the belt drive.

[0009] The driven pulley, driving pulley, and belt are equipped with protective covers on their outer sides. The outer ends of the protective covers have flanges that bend towards the cylinder's axis. A protective net is fixed to the inner side of the flange, and a clearance opening is provided in the center of the bottom of the protective net to allow passage for the rotating shaft. The protective covers effectively protect the driven pulley, driving pulley, and belt, preventing operators from contacting hazardous parts. The protective net inside the flange provides further protection and facilitates observation of the transmission components' operation, while the clearance opening provides space for the rotating shaft and facilitates the installation of the protective net.

[0010] A support platform is located at the bottom of the cylinder. One end of the support platform is fixed to a bracket, and the bottom of the other end of the support platform is fixed to a support plate, which is then fixed to a fixed plate. A vertical section is located at the bottom of the protective cover, and this vertical section is bolted to the support plate. The support platform can hold the container that receives the ceramic balls and materials after milling. The vertical section at the bottom of the protective cover is bolted to the support plate, ensuring the stability of the protective cover installation and improving the reliability of the overall structure.

[0011] The bottom of the base frame is fixed with a shock-absorbing rubber layer. Ear plates are fixed to both ends and the front and rear sides of the base frame. Anchor bolts are installed in the ear holes of the ear plates, with limit nuts connected to the upper part of the anchor bolts. Rubber buffer pads are located below the limit nuts, with the lower ends of the rubber buffer pads embedded in the inner holes of the ear plates. The shock-absorbing rubber layer at the bottom of the base frame and the rubber buffer pads that mate with the anchor bolts in the ear plates work together to effectively buffer the vibrations generated during device operation, reducing collision noise and damage to equipment components, thus extending the service life of the device.

[0012] This utility model has the following beneficial effects:

[0013] The cylinder and the sealing cover are separate and detachable structures, which facilitates manufacturing and maintenance. Both the cylinder and the sealing cover have polyurethane layers on the inside, and the cover plate also has polyurethane blocks, which are more wear-resistant and extend service life. The polyurethane blocks are replaceable for easy replacement. The annular bosses and annular concave platforms of polyurethane layer one and polyurethane layer two form a labyrinth seal. Combined with the fit of the polyurethane blocks and the inlet and outlet, a reliable seal is achieved between the cylinder and the sealing cover to prevent leakage of abrasive materials. At the same time, the quick-release mechanism facilitates the loading and unloading of ceramic balls and abrasive materials, effectively improving the efficiency of the test.
