Description

Technical Field

[0001] This invention relates to the field of activated carbon production equipment technology, and in particular to a cleaning device for activated carbon preparation. Background Technology

[0002] Activated carbon is a specially treated type of carbon. Organic raw materials (such as fruit shells, coal, and wood) are heated in the absence of air to reduce non-carbon components (a process called carbonization). They then react with gases, causing surface erosion and creating a highly porous structure (a process called activation). Because activation is a microscopic process, involving numerous point-like erosions of molecular carbides, activated carbon has countless tiny pores on its surface.

[0003] Activated carbon needs to be cleaned during its preparation to remove ash from its surface. In existing cleaning devices, activated carbon particles typically accumulate at the bottom of the cleaning tank, resulting in smaller gaps between the particles and hindering the removal of ash from the activated carbon surface. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device for the preparation of activated carbon, which can increase the spacing between activated carbon particles, avoid accumulation, and allow the cleaning liquid to fully contact the surface of the activated carbon particles to facilitate the removal of ash.

[0005] To achieve the above objectives, the following technical solution is adopted: a cleaning device for activated carbon preparation, comprising a cleaning cylinder, a stirring mechanism, and a driving mechanism. A protrusion is provided at the center of the bottom of the cleaning cylinder. The stirring mechanism is located directly above the protrusion, and a first push plate is connected to the lower end of the stirring mechanism. The driving mechanism is located at the top of the outer side of the cleaning cylinder and drives the stirring mechanism to rotate and move up and down reciprocally, so that the distance between the first push plate and the protrusion varies within a predetermined range.

[0006] Preferably, the stirring mechanism includes a stirring shaft and stirring blades. The stirring blades are evenly distributed on the lower peripheral wall of the stirring shaft, and the lower ends of multiple stirring blades are fixedly connected to the first push plate. The driving mechanism includes a driving motor, which is fixed to the top of the cleaning cylinder by a mounting base. An eccentric gear is connected to the output end of the driving motor. A driven gear is connected to the upper end of the stirring shaft through the cleaning cylinder. The driven gear meshes with the eccentric gear, and a return spring is sleeved on the stirring shaft located between the driven gear and the cleaning cylinder.

[0007] Preferably, the stirring blades are provided with through holes evenly distributed.

[0008] Preferably, the wall of the cleaning cylinder has an outwardly convex arc-shaped surface structure.

[0009] Preferably, the cleaning cylinder has a feed inlet at the top and a discharge outlet at the bottom, with a switch valve installed on the discharge outlet.

[0010] Preferably, the upper ends of the stirring blades are connected to a second pusher plate.

[0011] Preferably, the second push plate has a downwardly recessed groove structure, and a drainage mechanism is evenly arranged on the second push plate.

[0012] Preferably, the drainage mechanism includes drainage holes, a fixing cover, and a float. The drainage holes are evenly distributed on the second push plate. The fixing cover is located below the drainage holes and connected to the second push plate. The interior of the fixing cover communicates with the drainage holes. The float is located inside the fixing cover and can move freely. The size of the float is larger than the diameter of the drainage holes. The fixing cover has an overall upward-opening mesh structure.

[0013] Preferably, the lower end face of the drainage hole is provided with a ball groove, which matches the float.

[0014] Preferably, a heating wire is arranged in a ring at the bottom of the cleaning cylinder.

[0015] Preferably, a support base is provided at the bottom of the cleaning cylinder.

[0016] The beneficial effects achieved by this invention are as follows:

[0017] Compared with existing technologies, the present invention provides a cleaning device for activated carbon preparation. Through a driving mechanism, a first pusher plate reciprocates up and down. During the downward movement of the first pusher plate, activated carbon particles located around the protrusions move towards the wall of the cleaning cylinder and tend to move upwards along the cylinder wall, thus moving the activated carbon particles to a predetermined height. This avoids or reduces the impact of accumulation on cleaning, improving the cleaning effect. It also increases the spacing between activated carbon particles during cleaning, ensuring sufficient contact with the cleaning liquid and making it easier to remove ash. By setting a second pusher plate and a diversion mechanism, the activated carbon particles form a circulating flow trajectory with the cleaning liquid, further preventing particle accumulation and increasing the contact area between the activated carbon particles and the cleaning liquid, thereby improving the cleaning effect.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] See appendix Figure 1-3 A cleaning device for activated carbon preparation includes a cleaning cylinder 1, a stirring mechanism 2, and a driving mechanism 3. A support base 8 is provided at the bottom of the cleaning cylinder 1. A protrusion 4 is provided at the center of the bottom of the cleaning cylinder 1. The protrusion has an inverted V-shape, inverted U-shape, or other structure that brings the activated carbon particles closer to the inner wall of the cleaning cylinder. The stirring mechanism 2 is located directly above the protrusion 4, and a first push plate 5 is connected to the lower end of the stirring mechanism 2. The driving mechanism 3 is located at the top outside the cleaning cylinder 1 and drives the stirring mechanism 2 to rotate and reciprocate up and down, thus increasing the distance between the first push plate 5 and the protrusion 4. Within a predetermined range, the stirring mechanism 2 is driven by the driving mechanism 3 to achieve cleaning. At the same time, the driving mechanism 3 causes the first push plate 5 to move up and down reciprocally. During the downward movement of the first push plate 5, the activated carbon particles located around the protrusion 4 move towards the wall of the cleaning cylinder 1 and tend to move upward along the wall of the cleaning cylinder 1, thus driving the activated carbon particles to move upward to a predetermined height. This avoids or reduces the impact of accumulation on cleaning, improves the cleaning effect, and increases the spacing between activated carbon particles during the cleaning process, allowing them to fully contact the cleaning liquid and making it easier to remove ash.

[0024] Specifically, the stirring mechanism 2 includes a stirring shaft 201 and stirring blades 202. The stirring blades 202 are evenly distributed on the lower peripheral wall of the stirring shaft 201. The lower ends of multiple stirring blades 202 are fixedly connected to the first push plate 5. The driving mechanism 3 includes a driving motor 301, which is fixed to the top of the cleaning cylinder 1 by a mounting base. An eccentric gear 302 is connected to the output end of the driving motor 301. A driven gear 303 is connected to the upper end of the stirring shaft 201 through the cleaning cylinder 1. The driven gear 303 meshes with the eccentric gear 302, and a return spring 304 is sleeved on the stirring shaft 201 located between the driven gear 303 and the cleaning cylinder 1. When the driving motor 301 starts, it drives the eccentric gear 302 to rotate. The rotation of the eccentric gear 302 drives the driven gear 303 to rotate, thereby driving the rotation of the stirring mechanism 2. Due to the action of the eccentric gear 302 and the return spring 304, the stirring mechanism 2 moves up and down simultaneously during rotation. The drive mechanism can also be replaced by other structures such as an electric telescopic rod or an electric telescopic rod combined with a motor, and is not limited to the above structures.

[0025] To reduce rotational resistance, the stirring blades 202 are uniformly provided with through holes, allowing the cleaning fluid to flow through the through holes.

[0026] In this embodiment, in order to conform to the movement trend of activated carbon particles and drive the activated carbon particles to move upward to the maximum height, the wall of the cleaning cylinder 1 has an outwardly convex arc-shaped surface structure.

[0027] In this embodiment, in order to facilitate the feeding and discharging of materials, the top of the cleaning cylinder 1 is provided with a feeding port and the bottom is provided with a discharging port, and the discharging port is provided with a switch valve.

[0028] In this embodiment, in order to further improve the cleaning effect, the upper end of the stirring blades 202 is connected to a second pusher plate 6, so that when the second pusher plate 6 moves upward, the cleaning liquid moves towards the wall of the cleaning cylinder 1 and moves downward along the wall of the cleaning cylinder 1, thereby causing the activated carbon particles to move with the cleaning liquid, further improving the cleaning effect.

[0029] In this embodiment, the second push plate 6 has a downwardly concave groove structure. A flow-guiding mechanism 7 is evenly arranged on the second push plate 6, so that when the second push plate 6 moves downward, the flow-guiding mechanism 7 is in a closed state. When the lower surface of the second push plate 6 contacts the cleaning liquid below, the cleaning liquid is poured into the concave structure of the second push plate 6. At this time, it moves downward synchronously with the first push plate 5, causing the cleaning liquid to flow downward from the center. When it reaches the bottom of the cleaning cylinder 1, it is evenly dispersed towards the cylinder wall, and after dispersion, it flows upward along the cylinder wall. Conversely, when the second push plate 6 moves upward, the flow-guiding mechanism 7 is activated, thus forming a circulating flow trajectory. This avoids the accumulation of activated carbon particles, increases the contact area between the activated carbon particles and the cleaning liquid, and increases the spacing between the particles, thereby improving the cleaning effect and making it easier to remove ash.

[0030] Specifically, the drainage mechanism 7 includes a drainage hole 701, a fixing cover 702, and a float 703. The drainage holes 701 are evenly arranged on the second push plate 6. The fixing cover 702 is located below the drainage holes 701 and connected to the second push plate 6. The interior of the fixing cover 702 communicates with the drainage holes 701. The float 703 is located inside the fixing cover 702 and can move freely. The size of the float 703 is larger than the aperture of the drainage holes 701. The fixing cover 702 has an upward-opening mesh structure. When the second push plate 6 moves downward, the float 703 cooperates with the drainage holes 701 to achieve a seal. At the same time, the cleaning fluid is poured into the groove on the upper surface of the second push plate 6 to create a flow effect. When the second push plate 6 moves upward, the pressure causes the float 703 to move away from the drainage holes 701, so that the drainage holes 701 are in a conductive state. When it moves to a predetermined height, the cleaning fluid is discharged through the drainage holes 701. This process is repeated to improve the cleaning effect.

[0031] In order to better match the float 703 with the drainage hole 701, a ball groove 704 is provided on the lower end face of the drainage hole 701, and the ball groove 704 matches the float 703.

[0032] To further improve the cleaning effect, an electric heating wire is arranged in a ring at the bottom of the cleaning cylinder 1.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
