Description

Technical Field

[0001] This utility model relates to the field of catalyst grinding technology, and in particular to a smart grinding device for cobalt-based catalysts. Background Technology

[0002] Cobalt-based catalysts are catalytic materials with important applications in energy conversion and chemical synthesis. The grinding process is one of the key steps in preparing high-quality catalysts. Grinding refines the particles of cobalt-based catalysts, significantly increasing their specific surface area and the exposure rate of active sites, thus enhancing catalytic performance. In the preparation process of cobalt-based catalysts, mechanical grinding is a crucial step in controlling the particle size and distribution. Existing technologies commonly use traditional grinding equipment, which has low grinding efficiency and relies heavily on manual experience to adjust grinding parameters. However, manually adjusting the roller spacing to control particle size can easily lead to uneven particle size distribution between batches, affecting the consistency of catalyst activity.

Detailed Implementation

[0018] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0019] like Figure 1-4 The cobalt-based catalyst intelligent grinding device shown includes a disc 100 and a grinding wheel 600 that rotate relative to each other. The disc 100 is driven to rotate by a first driving mechanism 300, and the grinding wheel 600 is driven to rotate by a second driving mechanism 800. The disc 100 and the grinding wheel 600 rotate in opposite directions to grind the catalyst material between them.

[0020] In one specific embodiment, the disc 100 is externally provided with a shell 200, which is a barrel-shaped structure with an open top. The disc 100 divides the shell 200 into upper and lower parts. The upper part of the disc 100 and the shell 200 form a material processing area, and the lower part of the disc 100 and the shell 200 form a transmission area. The first drive mechanism 300 is disposed in the transmission area. The catalyst material is placed in the material processing area for processing. Furthermore, a material discharge notch 400 is provided on the side of the material processing area. A guide rod 500 extending into the material processing area is provided at the material discharge opening 400. More specifically, the material discharge opening 400 is opened on the side wall of the outer shell 200. When the disc 100 rotates, the guide rod 500 can guide the material to the grinding area. A grinding wheel 600 is provided at the top of the material processing area. Specifically, the grinding wheel 600 is located at the movable end of a lifting mechanism 700. The movable end of the lifting mechanism 700 can move in the height direction. The particle size of the material can be adjusted by controlling the distance between the grinding wheel 600 and the disc 100.

[0021] The prepared catalyst material is placed on the disc 100 in the material processing area. The first drive mechanism 300 is started to drive the disc 100 to rotate, and the second drive mechanism 800 is started to drive the grinding wheel 600 to rotate. The two are adjusted to rotate in opposite directions, and the catalyst material rotates synchronously with the disc 100. Under the guidance of the guide rod 500, the catalyst material enters the grinding wheel 600 and the disc 100 for grinding. It is important to note that the guide rod 500 should be as close as possible to the upper surface of the disc 100 to improve the material guiding efficiency. In addition, it should be close to one side of the unloading notch 400. The effective length of the guide rod 500 in the material processing area should not be less than the radius of the disc 100 to prevent the material in the central area from not being able to contact the guide rod 500 and forming a blind spot. In addition, it is important to note that when the disc 100 rotates in the first direction, the material is guided into the bottom of the grinding wheel 600 by the guide rod 500. When the disc 100 rotates in the second direction (the opposite of the first direction), the material is guided out of the discharge notch 400 by the guide rod 500.

[0022] like Figure 1 In this view, with the front end of the guide rod 500 as the reference direction, when looking down at the disc 100, clockwise rotation is for unloading and clockwise rotation is for feeding.

[0023] In addition, to prevent material from splashing during grinding, an annular cover plate 210 is provided at the top opening of the outer casing 200. The annular cover plate 210 covers part of the opening area, providing a certain degree of coverage. Furthermore, a cylinder 410 is also provided on one side of the opening, as can be seen from [reference needed]. Figure 1 and Figure 4 In this design, the telescopic rod of the cylinder 410 is movably connected to one end of the guide rod 500. Specifically, a connecting piece is movably mounted at the front end of the telescopic rod of the cylinder 410, and a lever is movably mounted at one end of the connecting piece. A through hole is formed at the top of the end of the guide rod 500 near the discharge notch 400, and the lever is movably inserted into this through hole. Furthermore, the end of the guide rod 500 near the discharge notch 400 is hinged to the bottom wall of the discharge notch 400 via a pin. By driving the guide rod 500 to rotate at a certain angle around the pin, the angle of the guide rod 500 can be adjusted, thereby further improving the material guiding efficiency.

[0024] In a preferred embodiment, the bottom edge of the grinding wheel 600 is rounded, which is more conducive to guiding the material into the bottom of the grinding wheel 600.

[0025] In one specific embodiment, reference Figure 1 and Figure 2The lifting mechanism 700 includes a base frame 710, a linear motion module 720, and an extension arm 730. The linear motion module 720 is vertically mounted on the base frame 710 and preferably uses a linear motor. The extension arm 730 is located at the movable end of the linear motor. A housing 740 is located at the front end of the extension arm 730. A vertical shaft 750 is rotatably mounted inside the housing 740. A grinding wheel 600 is located at the lower end of the vertical shaft 750. A second drive mechanism 800 is mounted on the lifting mechanism 700. Specifically... In this embodiment, the second drive mechanism 800 includes a second drive motor 810 disposed on one side of the housing 740. A first gear 820 is disposed on the output shaft of the second drive motor 810, and a second gear 830 is disposed on the vertical shaft 750. The first gear 820 and the second gear 830 mesh and transmit power. The second drive motor 810 is also provided with a motor housing. The first gear 820 is driven to rotate by the second drive motor 810, and the grinding wheel 600 is driven to rotate by the second gear 830 and the vertical shaft 750.

[0026] To enhance the adaptability of this device, the position of the grinding wheel 600 is adjustable. Specifically, the extension arm 730 consists of a body 731 and a slider 732. A slide rail 733 is provided on the body 731, and the slider 732 is mounted on the body 731 and slides in cooperation with the slide rail 733. The housing 740 is located at the bottom of the slider 732 and moves synchronously with the slider. Furthermore, an adjustment threaded hole 734 is provided on the side of the slider 732, and an adjustment knob 735 is provided at the adjustment threaded hole 734. By providing the adjustment knob 735, the slider 732 can be manually locked and released. In addition, a distance scale mark 736 is provided on the body 731, and a pointer 737 pointing to the distance scale mark 736 is provided on the slider 732. The distance scale mark 736 facilitates the observation of the adjustment distance of the housing 740.

[0027] In one specific embodiment, reference Figure 3 The first driving mechanism 300 specifically includes a disk frame 310 and a first driving motor 320. The disk frame 310 is parallel to the disk 100 and is connected to the inner bottom wall of the outer casing 200 via multiple columns 330. The disk frame 310 and the disk 100 are connected via a third gear 340, which is rotatably connected to the disk frame 310. A circular protrusion is formed in the central area of ​​the disk frame 310, and this circular protrusion is connected to the third gear 340 via a bearing. The third gear is fixedly connected to the disk 100 via bolts. The first driving motor 320 is mounted on the disk frame 310, and the output shaft of the first driving motor 320 passes through the disk frame 310. A fourth gear 350 is provided at the upper end of the output shaft, and the fourth gear 350 is connected to the third gear in a transmission manner. The first driving motor 320 drives the disk 100 to rotate through the fourth gear 350 and the third gear 340.

[0028] Both the first drive motor 320 and the second drive motor 810 mentioned above are servo motors.
