Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball mill technology, specifically a wet solid-phase mechanical ball mill for the preparation of metal catalysts. Background Technology
[0002] In the field of metal catalyst preparation, the material grinding and catalytic reaction process is mostly divided into two steps. Traditional mechanical ball mills, during the grinding process, make it difficult for the material to be fully impacted and mixed. Their transmission structure design is simple, making it difficult to carry out chemical catalysis while grinding, thereby enhancing the preparation effect. This results in low preparation efficiency and slows down the subsequent catalytic reaction. In the catalytic reaction stage, the contact between the chemical reagent and the material is not sufficient. The chemical reagent is difficult to flow in the fixed container and is difficult to mix with the material quickly and evenly, resulting in low catalytic reaction efficiency. The quality of the prepared metal catalysts is inconsistent and cannot meet the growing demand for metal catalysts in industrial production. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this invention provides a wet solid-phase mechanical ball mill for the preparation of metal catalysts. The rotating device and the stirring device work together to improve the grinding effect and catalytic reaction efficiency, while the locking device ensures the sealing and stability of the ball mill during operation, providing a reliable guarantee for the preparation of metal catalysts.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a wet solid-phase mechanical ball mill for preparing metal catalysts, comprising a base, a DC motor fixedly connected to the outer wall of the base, a drive gear fixedly connected to the output end of the DC motor, a rotating cylinder rotatably connected to the outer wall of the base, a driven gear fixedly connected to the outer wall of the rotating cylinder, a threaded rod rotatably connected to the inner wall of the rotating cylinder, and a movable door threadedly connected to the outer surface of the threaded rod; further comprising: a stirring device, the outer wall of which is fixedly connected to the inner wall of the rotating cylinder; and a rotating device, the outer wall of which is fixedly connected to the outer wall of the base. A locking device is provided, the outer wall of which is fixedly connected to the outer wall of the rotating cylinder. The rotating device includes a servo motor, the output end of which is fixedly connected to a connecting shaft. A rolling cylinder is fixedly connected to the outer wall of the connecting shaft. A lifting groove is provided on the inner side wall of the rolling cylinder, and a through hole is provided in the wall of the rolling cylinder. By rotating the rolling cylinder and the rotating cylinder in opposite directions in the rotating device, the lifting groove lifts and drops the material to enhance grinding. At the same time, the stirring device uses the centrifugal force of the offset sleeve to deflect and accelerate the flow of chemical reagents in the interlayer, promoting full contact between them and the material. This not only improves the grinding effect but also increases the catalytic reaction efficiency, thereby improving the quality of metal catalyst preparation.
[0007] Preferably, the outer wall of the servo motor is fixedly connected to the outer wall of the base, the outer wall of the connecting shaft is rotatably connected to the outer wall of the base, the outer wall of the rolling cylinder is rotatably connected to the inner wall of the rotating cylinder, the driving gear meshes with the driven gear, and the outer wall of the movable door is slidably connected to the outer wall of the rotating cylinder.

By rotating the bidirectional screw through the locking device, the clamping block drives the friction plate to abut against the connecting plate, locking the threaded rod. This effectively prevents the threaded rod from rotating due to the rotational inertia of the rotating cylinder, prevents chemical leakage, ensures the sealing of the ball mill during operation, and maintains a stable working state.

[0011] This invention provides a wet solid-phase mechanical ball mill for the preparation of metal catalysts. It has the following beneficial effects:
[0012] (i) The wet solid-phase mechanical ball mill for preparing the metal catalyst uses a rotating device where the rolling drum and the rotating drum rotate in opposite directions. The lifting tank lifts and drops the material to enhance grinding. At the same time, the stirring device uses the centrifugal force of the offset sleeve to deflect the chemical agent, which accelerates the flow of the chemical agent in the jacket and promotes its full contact with the material. This not only improves the grinding effect but also increases the catalytic reaction efficiency, thereby improving the quality of metal catalyst preparation.
[0013] (II) The wet solid-phase mechanical ball mill prepared by the metal catalyst uses a locking device to rotate the bidirectional screw, causing the clamping block to drive the friction plate to abut against the connecting plate and lock the threaded rod. This effectively prevents the threaded rod from rotating due to the rotational inertia of the rotating cylinder, prevents chemical leakage, ensures the sealing of the ball mill during operation, maintains a stable working state, and ensures that the catalytic reaction is not disturbed.

Fixed connection; the rotating device 7 includes a servo motor 71, the output end of which is fixedly connected to a connecting shaft 72, and a rolling cylinder 73 is fixedly connected to the outer wall of the connecting shaft 72. The inner side wall of the rolling cylinder 73 is provided with a lifting groove 74, and the wall of the rolling cylinder 73 is provided with a through hole 75. The servo motor 71 is fixed to the outer wall of the base 1. After starting, the connecting shaft 72 at its output end drives the rolling cylinder 73 to rotate, and the rotating cylinder 5 and the rolling cylinder 73 rotate in opposite directions. The lifting groove 74 and the through hole 75 in the inner side wall of the rolling cylinder 73 play an important role. The lifting groove 74 can intermittently lift the iron ball and solid material in the rolling cylinder 73, and make it fall under the action of gravity, thereby enhancing the impact and grinding effect on the material.
[0024] The outer wall of the servo motor 71 is fixedly connected to the outer wall of the base 1, the outer wall of the connecting shaft 72 is rotatably connected to the outer wall of the base 1, the outer wall of the rolling cylinder 73 is rotatably connected to the inner wall of the rotating cylinder 5, the driving gear 3 meshes with the driven gear 4, and the outer wall of the movable door 9 is slidably connected to the outer wall of the rotating cylinder 5.
[0025] The agitation device 6 includes a connecting ring 61, a fixed column 62 fixedly connected to the outer wall of the connecting ring 61, and an offset sleeve 63 rotatably connected to the outer wall of the fixed column 62. The outer wall of the connecting ring 61 is fixedly connected to the inside of the rotating cylinder 5. The connecting ring 61 is fixed inside the rotating cylinder 5. When the rotating cylinder 5 rotates, the connecting ring 61 rotates accordingly, and the fixed column 62 and the offset sleeve 63 also move together. The offset sleeve 63 is rotatably connected to the fixed column 62. During the rotation, the offset sleeve 63 will deflect due to centrifugal force because its center is not at the axis of the fixed column 62. The agitation device 6 is located in the interlayer between the rotating cylinder 5 and the rolling cylinder 73, which can accelerate the flow of chemical agents and promote the outflow and entry of chemical agents into the rolling cylinder 73.

When the bidirectional screw 103 inside the fixing block 102 is rotated, the clamping blocks 104 symmetrically threaded on the outer wall of the bidirectional screw 103 will move towards each other under the action of the threads, so that the friction plate 105 on the outer wall of the clamping block 104 tightly abuts against the outer wall of the connecting disc 101, thereby locking the connecting disc 101 and preventing the threaded rod 8 from rotating due to inertia during the rotation of the rotating cylinder 5, thus preventing the chemical agent from flowing out of the rotating cylinder 5.
[0027] In use, the base 1 serves as a basic support structure, providing an installation platform for other components. The DC motor 2 is fixed to the outer wall of the base 1. After starting, its output end drives the drive gear 3 to rotate. The drive gear 3 meshes with the driven gear 4, causing the driven gear 4 to drive the rotating cylinder 5 to rotate around the outer wall of the base 1. The threaded rod 8 is rotatably connected to the outer wall of the rotating cylinder 5, and its outer surface is threadedly connected to the movable door 9. Rotating the threaded rod 8 allows the movable door 9 to slide along its thread direction on the outer wall of the rotating cylinder 5, realizing the opening and closing of the opening position on the rotating cylinder 5, which facilitates the injection and removal of chemical agents.
[0028] The locking device 10 locks the threaded rod 8 before the rotating cylinder 5 rotates. The connecting plate 101 is fixedly connected to the outer wall of the threaded rod 8. The fixing block 102 is fixed to the outer wall of the rotating cylinder 5. When the bidirectional screw 103 inside the fixing block 102 is rotated, the clamping blocks 104 symmetrically threaded on the outer wall of the bidirectional screw 103 will move towards each other under the action of the threads, so that the friction plate 105 on the outer wall of the clamping block 104 tightly abuts against the outer wall of the connecting plate 101, thereby locking the connecting plate 101 and preventing the threaded rod 8 from rotating due to inertia during the rotation of the rotating cylinder 5, preventing the chemical agent from flowing out of the rotating cylinder 5, and ensuring the sealing and stability of the ball mill during operation.
[0029] The rotating device 7 consists of a servo motor 71, a connecting shaft 72, and a rolling drum 73. The servo motor 71 is fixed to the outer wall of the base 1. After starting, the connecting shaft 72 at its output end drives the rolling drum 73 to rotate. The rotating drum 5 and the rolling drum 73 rotate in opposite directions. The lifting groove 74 on the inner side wall of the rolling drum 73 and the through hole 75 in the wall play an important role. The lifting groove 74 can intermittently lift the iron balls and solid materials in the rolling drum 73 and make them fall under the action of gravity, thereby enhancing the impact and grinding effect on the materials. After the chemical agent is injected into the interlayer between the rotating drum 5 and the rolling drum 73, it can enter the interior of the rolling drum 73 through the through hole 75 to assist the catalytic reaction.
[0030] The stirring device 6 includes a connecting ring 61, a fixed column 62, and an offset sleeve 63. The connecting ring 61 is fixed inside the rotating cylinder 5. When the rotating cylinder 5 rotates, the connecting ring 61 rotates accordingly, and the fixed column 62 and the offset sleeve 63 also move together. The offset sleeve 63 is rotatably connected to the fixed column 62. During the rotation, the offset sleeve 63 will deflect due to centrifugal force because its center is not at the axis of the fixed column 62. The stirring device 6 is located in the interlayer between the rotating cylinder 5 and the rolling cylinder 73, which can accelerate the flow of chemical reagents, promote the outflow and inflow of chemical reagents into the rolling cylinder 73, make the chemical reagents and materials more fully contacted, improve the catalytic reaction efficiency, and further improve the preparation quality of the metal catalyst.
