Description

Technical Field

[0001] This utility model relates to the field of activated carbon production technology, specifically to a multi-stage crushing structure for activated carbon. Background Technology

[0002] Activated carbon plays a vital role in numerous industrial sectors and environmental applications. For instance, in wastewater treatment, its porous structure effectively adsorbs impurities, heavy metal ions, and organic pollutants, aiding in water purification. In air purification, it adsorbs harmful gases such as formaldehyde and benzene, improving indoor air quality. However, different applications often have specific requirements for the particle size of activated carbon, as particle size directly affects key indicators such as specific surface area and adsorption performance. Therefore, to better adapt to diverse application needs, precisely controlling the particle size of activated carbon has become one of the key issues that the industry urgently needs to address.

[0003] However, in actual use, without a suitable screening process, the activated carbon particles that have already reached the application standard particle size will continue to be crushed as the crushing time and the number of crushing times increase. This results in the activated carbon particles becoming increasingly fine, which not only fails to meet the requirements of particle size accuracy in actual applications, but also may damage the pore structure and other properties of activated carbon due to excessive crushing, affecting its original good adsorption and catalytic performance, and ultimately reducing the overall use value of activated carbon products in various application fields.

[0004] Therefore, we propose a multi-stage crushing structure for activated carbon. Utility Model Content

[0015] Compared with the prior art, this utility model provides a multi-stage crushing structure for activated carbon, which has the following beneficial effects:

[0016] 1. This activated carbon features a multi-stage crushing structure. To prevent activated carbon that meets the standard from being crushed multiple times, resulting in overly fine activated carbon, a screening component is incorporated, along with a support, motor, rotating rod, stirring block, screen, conical inlet, dustproof plate, conical plate, inclined plate, feed inlet, sensor, and crushing components, to screen the activated carbon and thus improve the crushing process.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a multi-stage crushing structure for activated carbon includes a main body 1, a support leg 2 fixedly installed under the main body 1, a crushing chamber 3 provided on the main body 1, a discharge port 4 provided below the crushing chamber 3, a screening chamber 5 fixedly connected to the crushing chamber 3, a feed port 6 provided on the screening chamber 5, and a screening component 7 provided inside the screening chamber 5.

[0026] In one embodiment of this utility model, the screening component 7 includes a support 71, on which the support 71 is fixedly mounted. A motor 72 is fixedly mounted on the support 71, and a rotating rod 73 is fixedly connected to the output end of the motor 72. A stirring block 74 is fixedly connected to the rotating rod 73. Multiple sets of stirring blocks 74 are arranged, mirror-imaged about the vertical centerline of the rotating rod 73 at its left and right ends. A screen 75 is fixedly connected to the rotating rod 73 and rotatably connected to the top of the screening chamber 5. When the motor 72 in the screening component 7 is started, its output end drives the rotating rod 73 to rotate. The multiple sets of stirring blocks 74 fixedly connected to the rotating rod 73 rotate together with the rotating rod 73, stirring the activated carbon material entering the screening chamber 5, ensuring it is evenly distributed on the screen 75. The screen is distributed in a way that facilitates subsequent screening operations. Simultaneously, the rotating rod 73 drives the screen 75 to rotate. A conical opening 76 is rotatably connected to the bottom of the screen 75, and a dustproof plate 77 is fixedly connected to the conical opening 76. The dustproof plate 77 is fixedly connected inside the screening chamber 5. A conical plate 78 is rotatably connected to the screen 75, and an inclined plate 79 is fixedly connected to the bottom of the conical plate 78. A feed port 710 is located at the bottom of the inclined plate 79 and is fixedly connected to the screening chamber 5. A sensor 711 is fixedly installed on the feed port 710. A crushing component 712 is located below the conical opening 76. During the rotation of the screen 75, smaller activated carbon particles will pass through the screen 75 and fall down. The dustproof plate 77 fixedly connected to the conical opening 76 can prevent dust from flying, thus playing a certain dustproof role. Activated carbon with smaller particle size that meets the screening requirements will pass through screen 75 and flow along screen 75 to cone plate 78, slide towards its bottom end, and finally continue to move along inclined plate 79 fixedly connected to cone plate 78. When the material slides to the feed port 710 at the bottom of inclined plate 79, sensor 711 fixedly installed on feed port 710 can sense the arrival of the material. When feed port 710 does not sense any material flowing out, cone port 76 is opened, so that larger activated carbon falls through cone port 76. Material at the corresponding position will enter crushing component 712 for further crushing, thus completing the multi-stage crushing process of activated carbon. The crushed material will finally be discharged through discharge port 4 set under crushing chamber 3.

[0027] In one embodiment of this utility model, a vibration component 8 is provided on the screening chamber 5, a striking block 81 is fixedly connected to the rotating rod 73, a support plate 82 is fixedly connected to the screening chamber 5, and a spring rod 83 is fixedly connected to the support plate 82. Multiple sets of spring rods 83 are arranged linearly at equal intervals on the support plate 82, and a sliding shell 84 is fixedly connected to the spring rod 83. When the rotating rod 73 rotates, the striking block 81 fixedly connected to it will also rotate. When the striking block 81 rotates to a certain position, it will impact the sliding shell 84 fixedly connected to the screening chamber 5. Multiple sets of spring rods 83 arranged linearly at equal intervals are fixedly connected to the support plate 82, and the sliding shell 84 is fixedly connected to the spring rod 83. After being impacted by the striking block 81, the entire structure formed by the spring rod 83 and the sliding shell 84 will vibrate, thereby causing the screening chamber 5 to vibrate, assisting the screen 75 to perform screening work better, thereby improving the material feeding work.

[0028] Working principle: When the motor 72 in the screening assembly 7 starts, the output end of the motor 72 drives the rotating rod 73 to start rotating. Multiple sets of stirring blocks 74 fixedly connected to the rotating rod 73 will rotate together with the rotating rod 73, stirring the activated carbon material entering the screening chamber 5, so that it can be evenly distributed on the screen 75, which is convenient for subsequent screening operations. At the same time, the rotating rod 73 drives the screen 75 to rotate. During the rotation of the screen 75, the activated carbon with smaller particle size will fall through the screen 75. The dustproof plate 77 fixedly connected to the conical opening 76 can prevent dust from flying and play a certain role in dust prevention. Smaller activated carbon particles that meet the screening requirements pass through screen 75 and flow along it to cone plate 78, sliding towards its bottom. They then continue moving along inclined plate 79 fixedly connected to cone plate 78. When the material reaches the discharge port 710 at the bottom of inclined plate 79, sensor 711, fixedly installed on discharge port 710, detects its arrival. If no material is detected at discharge port 710, cone port 76 opens, allowing larger activated carbon particles to fall through. Material at the corresponding position enters crushing component 712 for further crushing, thus completing the multi-stage crushing process for activated carbon. After crushing, the material will eventually be discharged through the discharge port 4 set under the crushing chamber 3. When the rotating rod 73 rotates, the striking block 81 fixedly connected to it will also rotate. When the striking block 81 rotates to a certain position, it will impact the sliding shell 84 fixedly connected to the screening chamber 5. Multiple sets of equally spaced linear array spring rods 83 are fixedly connected to the support plate 82. The sliding shell 84 is fixedly connected to the spring rods 83. After being impacted by the striking block 81, the entire structure formed by the spring rods 83 and the sliding shell 84 will vibrate, thereby driving the screening chamber 5 to vibrate, assisting the screen 75 to perform screening work better, thereby improving the material feeding work.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
