Description

Technical Field

[0001] The utility model relates to the technical field of catalyst preparation, in particular to a feeding device for catalyst preparation. Background Art

[0002] Bimetallic nanoparticle catalysts, composed of two different metals, have broad application prospects, particularly in the environmental protection, chemical, and energy sectors. However, the preparation of bimetallic nanoparticle catalysts requires a feeding device.

[0003] Chinese patent publication CN220861394U discloses a catalyst feeding device for the petrochemical industry, comprising a feeding device fixedly mounted on the surface of a bracket, a filter plate fixedly mounted on the inner wall of the feeding device, a pricked plate fixedly mounted on the surface of the filter plate, the bracket fixedly mounted on the surface of a base, a processing tank fixedly mounted on the surface of the base, a fixed plate fixedly mounted on the surface of the bracket, a motor fixedly mounted on the surface of the fixed plate, and a control assembly disposed on the surface of the fixed plate. The output shaft of the motor drives a disc to rotate on the surface of the fixed plate, and a support rod and a protrusion fixed to the surface of the disc rotate synchronously and contact the inner wall of an arc-shaped rod. When the arc-shaped rod is subjected to force, a crossbar fixed to the surface of the arc-shaped rod can move laterally under the restraint of a limit block. A flat rod fixed to the surface of the crossbar drives a moving rod to move under the support of a spring, and the pricked plate fixed to the surface of the moving rod moves synchronously, working together with the pricked plate to break up catalyst agglomerated on the filter plate.

[0004] The disadvantage of the above-mentioned scheme is that although the agglomerated catalyst can be broken up by combining the cone-pierced plate and the needle-pierced plate, the catalyst will accumulate together after being broken up, thereby affecting the filtration efficiency of the filter plate on the catalyst and reducing the feeding rate in the processing tank. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a feeding device for catalyst preparation, which drives the filter plate to move vertically through the transmission component to improve the filtering efficiency of the filter plate, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding device for catalyst preparation, comprising a feeding barrel, a filter plate slidingly arranged inside the feeding barrel, a processing box fixedly arranged at the bottom of the feeding barrel, a motor fixedly arranged on the top of the processing box, a connecting shaft fixedly arranged on the output shaft of the motor, and a transmission component that drives the filter plate to move vertically is arranged between the connecting shaft and the feeding barrel; a fixed plate is fixedly arranged on the top of the processing box, a connecting plate slidingly arranged inside the fixed plate, a knocking block is fixedly arranged at one end of the connecting plate, a circular plate is fixedly arranged on the connecting shaft, and a reciprocating component that drives the connecting plate to move back and forth is arranged on the circular plate.

[0007] Furthermore, the transmission assembly includes a rotating shaft, which horizontally passes through the feeding barrel and is rotatably connected to the feeding barrel. A cam is fixedly provided at one end of the rotating shaft, and the cam slides with the filter plate. A second bevel gear is fixedly provided at the other end of the rotating shaft, and a first bevel gear is fixedly sleeved on the connecting shaft, and the first bevel gear is meshed with the second bevel gear.

[0008] Furthermore, the feeding barrel is provided with a plurality of telescopic rods arranged in a circumferential array, the tops of the plurality of telescopic rods are fixedly connected to the filter plate, the bottoms of the telescopic rods are fixedly provided with a connecting block, the connecting block is fixedly connected to the feeding barrel, and a spring is provided between the connecting block and the filter plate.

[0009] Furthermore, the reciprocating assembly includes a connecting column, which is fixedly arranged on the top of the circular plate. A slot plate is slidably arranged on the connecting column, and the slot plate is fixedly connected to the connecting plate.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] Because a connecting shaft is fixedly mounted on the output shaft of the motor, a transmission assembly is provided between the connecting shaft and the feeding bucket to drive the filter plate to move vertically. Therefore, when the connecting shaft rotates, the connecting shaft drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the rotating shaft to rotate, which in turn drives the cam to rotate. During the rotation of the cam, it slides with the bottom surface of the filter plate, thereby driving the filter plate to move up and down reciprocatingly, allowing the raw materials on the top of the filter plate to pass through the filter plate quickly, accelerating the filter plate's filtration speed and increasing the rate of feeding the material into the processing box.

A motor 6 is fixedly arranged on the top of the processing box 1, and the motor 6 is located on one side of the feeding barrel 2. A fixed plate 12 is fixedly arranged on the top of the processing box 1, and a connecting plate 11 is slidably arranged inside the fixed plate 12, and the connecting plate 11 passes through the fixed plate 12 horizontally. A knocking block 13 is fixedly arranged at one end of the connecting plate 11, which is used to knock on the feeding barrel 2 to make the feeding barrel 2 vibrate, thereby shaking off the raw materials adhering to the inner wall of the feeding barrel 2.

[0018] The output shaft of the motor 6 is coaxially fixed with a connecting shaft 7, and the top fixed sleeve of the connecting shaft 7 is provided with a circular plate 8. A reciprocating assembly that drives the connecting plate 11 to reciprocate is provided on the circular plate 8. The reciprocating assembly includes a connecting column 9, which is fixed at an eccentric position on the top of the circular plate 8. The outer sliding sleeve of the connecting column 9 is provided with a slot plate 10. The horizontal cross-section of the slot plate 10 is a long strip frame structure with arcs at both ends. One side of the slot plate 10 is fixedly connected to the connecting plate 11.

[0019] A transmission assembly that drives the filter plate 5 vertically is disposed between the connecting shaft 7 and the feeding barrel 2. The transmission assembly includes a rotating shaft 16 that horizontally passes through the feeding barrel 2 and is rotatably connected to the feeding barrel 2. A cam 17 is fixedly mounted on one end of the rotating shaft 16 within the feeding barrel 2. The cam 17 slides with the bottom of the filter plate 5 and drives the filter plate 5 upward. A second bevel gear 15 is fixedly mounted on the other end of the rotating shaft 16. A first bevel gear 14 is fixedly mounted on the connecting shaft 7 and meshes with the second bevel gear 15.

[0020] Inside the feeding bucket 2, multiple telescopic rods 3 are arranged in a circumferential array. The tops of the multiple telescopic rods 3 are fixedly connected to the filter plate 5. The bottoms of the telescopic rods 3 are fixedly provided with connecting blocks, which are fixedly connected to the feeding bucket 2. A spring 4 is provided between the connecting block and the filter plate 5.

[0021] The working principle of a catalyst preparation feeding device provided in this embodiment is as follows:

[0022] Put the required raw materials into the feeding barrel 2, start the motor 6, the motor 6 drives the connecting shaft 7 to rotate, the connecting shaft 7 drives the circular plate 8 to rotate, the circular plate 8 drives the connecting column 9 to rotate, when the connecting column 9 rotates, it slides in the slot plate 10 and drives the slot plate 10 to move back and forth, the slot plate 10 drives the knocking block 13 to move back and forth through the connecting plate 11 and knocks the feeding barrel 2, which can shake off the raw materials adhering to the inner wall of the feeding barrel 2.

[0023] The rotation of the connecting shaft 7 also drives the first bevel gear 14 to rotate, the first bevel gear 14 drives the second bevel gear 15 to rotate, the second bevel gear 15 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the cam 17 to rotate. During the rotation of the cam 17, it slides with the bottom surface of the filter plate 5, thereby driving the filter plate 5 to move back and forth, so that the raw material on the top of the filter plate 5 passes through the filter plate 5 quickly, thereby accelerating the speed at which the filter plate 5 filters the raw material.

[0024] At the same time, the filter plate 5 stretches the spring 4 during its up and down movement, and cooperates with the restoring force of the spring 4 to make the filter plate 5 vibrate up and down, further accelerating the rate at which the raw materials pass through the filter plate 5, and the filtered raw materials fall into the processing box 1.
