Description

Technical Field

[0001] This utility model relates to the field of activated carbon production technology, specifically a processing device for preparing activated carbon from coconut shells. Background Technology

[0002] Activated carbon made primarily from fruit shells and sawdust is produced through carbonization, activation, and refining. It features a large specific surface area, high strength, uniform particle size, well-developed pore structure, and strong adsorption capacity. It effectively adsorbs free chlorine, phenols, sulfur, oil, colloids, pesticide residues, and other organic pollutants from water, as well as aiding in the recovery of organic solvents. It is suitable for use in the pharmaceutical, petrochemical, sugar refining, beverage, and alcohol purification industries for decolorization, refining, purification of organic solvents, and wastewater treatment.

[0003] According to a public notice of a processing device for preparing activated carbon using coconut shells (Announcement No.: CN118811816A), in the above application, after being collected by the gas collecting hopper, the activated carbon enters the air inlet chamber along the connecting air passage. It is first guided by the annular guide plate and then enters the diluent storage pool formed by the combination of the annular partition plate and the air inlet chamber, where it is diluted by the diluent.

[0004] However, in actual use, the contact efficiency between the crushed coconut shell powder and the powder in the activation chamber is limited, resulting in poor dispersion efficiency of the coconut shell powder and thus reducing the activation and carbonization efficiency of the coconut shell powder. In view of this, we propose a processing device for preparing activated carbon from coconut shells. Utility Model Content

[0005] The purpose of this invention is to provide a processing device for preparing activated carbon from coconut shells, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a processing device for preparing activated carbon from coconut shells, comprising an activation chamber, a crushing chamber fixedly installed on the top of the activation chamber, a feed inlet on the top side wall of the crushing chamber, a drive motor fixedly installed on the top outer wall of the crushing chamber, a crushing mechanism inside the crushing chamber, and a dispersing component inside the activation chamber.

[0007] The dispersion component includes a servo motor, which is fixedly installed on the outer wall of the end of the activation chamber. A small gear is fixedly installed on the output end of the servo motor. A rotating drum is rotatably installed through the inner wall of the activation chamber. A large gear is fixedly installed on the arc-shaped outer wall of the end of the rotating drum. A spiral blade is fixedly installed on the arc-shaped outer wall of the rotating drum. An air outlet plate is rotatably installed through the arc-shaped outer wall of the rotating drum. An air outlet is provided on the inner wall of the air outlet plate. A fixed pipe is rotatably connected to the end of the rotating drum. An air pump is fixedly connected to the end of the fixed pipe away from the rotating drum. A feeding cylinder is fixedly installed on the side wall of the fixed pipe.

[0008] Preferably, the large gear and the small gear mesh to achieve transmission, and the diameter ratio of the small gear to the large gear is 1:2, so that when the servo motor starts, it cooperates with the transmission of the small gear and the large gear to enable the drum to rotate at a relatively slow speed.

[0009] Preferably, the spiral blades are arranged in two sets, and the two sets of spiral blades are mirror images of each other with the vertical central axis of the activation chamber as the axis of symmetry, and the spiral blades are arranged in an inclined shape with the top of the spiral blades away from the center of the activation chamber.

[0010] Preferably, the rotating drum has an air hole on one side inside the air outlet plate that is connected to the air blowing port, so that the mixture of activator and air entering the rotating drum can be blown into the activation chamber through the air blowing port.

[0011] Preferably, the activation chamber is provided with a shovel assembly, which includes an arc-shaped groove on the arc-shaped inner surface of the activation chamber. An air guide pipe is fixedly installed on the arc-shaped outer wall of the rotating cylinder. A shovel plate is fixedly installed at the end of the air guide pipe away from the rotating cylinder. An arc-shaped plate is fixedly installed on the outer wall of the shovel plate near the center of the activation chamber. Small air holes are provided on the arc-shaped outer wall of the air guide pipe near the shovel plate.

[0012] Preferably, the arc-shaped groove is arranged with a low center and high ends, that is, the interior of the activation chamber is arranged with a wide center and narrow ends, and the surface of the shovel plate away from the air guide pipe is adapted to the shape of the arc-shaped groove, so that when the drum rotates, it can work with the shovel plate to scoop up the coconut shell powder in the arc-shaped groove.

[0013] Preferably, the number of the arc-shaped plates is set in multiple sets, and the multiple sets of arc-shaped plates are mirror images of each other on the left and right sides of the air guide pipe. The top of the arc-shaped plates is inclined towards the center of the activation chamber, and the inclination angle of the multiple sets of arc-shaped plates increases as the distance between them and the air guide pipe increases.

[0014] Compared with the prior art, this utility model provides a processing device for preparing activated carbon from coconut shells, which has the following beneficial effects:

[0015] 1. The processing device for preparing activated carbon from coconut shells is equipped with a dispersion component. When the servo motor and air pump are started, the mixture of activator and air entering the rotating drum can be blown into the activation chamber through the air blowing port. Guided by the surface of the spiral blades, the airflow entering the activation chamber moves in a spiral shape towards the center of the activation chamber. This allows the mixture of activator and air to be dispersed to various areas, thus ensuring sufficient contact with the coconut shell powder and guaranteeing the activation effect of the coconut shell powder. This, in turn, ensures the processing effect of the activated carbon prepared from the coconut shell powder.

[0016] 2. The processing device for preparing activated carbon from coconut shells is equipped with a shovel assembly. When the air guide pipe drives the shovel plate to rotate, the shovel plate shovels up the coconut shell powder from the arc groove. Then, the activator-air mixture blown out by the air guide pipe can work with the arc plates with different inclination angles to blow the coconut shell powder and the mixture into the gap between the spiral plates, thereby further improving the contact efficiency between the coconut shell powder and the activator-air mixture, thus improving the activation efficiency of the coconut shell.

[0022] like Figures 1-4As shown, this utility model provides a technical solution: a processing device for preparing activated carbon from coconut shells, including an activation chamber 1, a crushing chamber 2 fixedly installed on the top of the activation chamber 1, a feed inlet 3 opened on the top side wall of the crushing chamber 2, a drive motor 4 fixedly installed on the top outer wall of the crushing chamber 2, a crushing mechanism 5 arranged inside the crushing chamber 2, and a dispersion component 6 arranged inside the activation chamber 1. The dispersion component 6 includes a servo motor 61, a small gear 62, a rotating drum 63, a large gear 64, a spiral blade 65, an air outlet 66, an air blowing port 661, a fixed pipe 67, an air pump 68, and a feeding cylinder 69.

[0023] In one embodiment of this utility model, a servo motor 61 is fixedly installed on the outer wall of the end of the activation chamber 1. A small gear 62 is fixedly installed on the output end of the servo motor 61. A rotating cylinder 63 is installed through and rotatably on the inner wall of the activation chamber 1. A large gear 64 is fixedly installed on the arc-shaped outer wall of the end of the rotating cylinder 63. A spiral blade 65 is fixedly installed on the arc-shaped outer wall of the rotating cylinder 63. An air outlet plate 66 is installed through and fixedly on the arc-shaped outer wall of the rotating cylinder 63. An air outlet 661 is opened on the inner wall of the air outlet plate 66. A fixed pipe 67 is rotatably connected to the end of the rotating cylinder 63. An air pump 68 is fixedly connected to the end of the fixed pipe 67 away from the rotating cylinder 63. A feeding cylinder 69 is fixedly installed on the side wall of the fixed pipe 67.

[0024] Furthermore, an outlet is provided on the inner wall at the bottom center of the activation chamber 1 so that the activated coconut shell powder can be discharged from the outlet. The outlet is controlled by a solenoid valve to open and close, and remains closed during device startup. Meanwhile, the crushing mechanism 5 includes multiple sets of crushing rollers of different types arranged vertically to work with the inner wall of the crushing chamber 2 to crush the coconut shells entering the crushing chamber 2. Screens are provided between the different types of crushing rollers to impede the coconut shells entering the crushing chamber 2, so that they can be crushed by the crushing rollers. At the same time, the bottom of the crushing chamber 2 is connected to the internal cavity of the activation chamber 1 so that the crushed coconut shell powder can fall into the activation chamber 1.

[0025] Furthermore, the large gear 64 meshes with the small gear 62 to achieve transmission, and the diameter ratio of the small gear 62 to the large gear 64 is 1:2. This allows the servo motor 61 to rotate at a relatively slow speed when starting, in conjunction with the transmission of the small gear 62 and the large gear 64. Additionally, two sets of spiral blades 65 are provided, mirror-image arranged about the vertical central axis of the activation chamber 1, and the spiral blades 65 are inclined with their tops away from the center of the activation chamber 1. Specifically, the rotating drum 63 is located inside the air outlet plate 66 on one side. An air hole is provided that is connected to the air outlet 661, so that the mixture of activator and air entering the rotating drum 63 can be blown into the activation chamber 1 through the air outlet 661. And guided by the surface of the spiral plate 65, the airflow entering the activation chamber 1 is spiraled towards the center of the activation chamber 1, so that the mixture of activator and air entering the activation chamber 1 can be dispersed to each area, thereby making full contact with the coconut shell powder, thus ensuring the activation effect of the coconut shell powder, and thus ensuring the processing effect of activated carbon prepared by using the coconut shell powder.

[0026] Specifically, an activator is placed inside the feeding cylinder 69, and when the air pump 68 is started, the gas flow rate in the internal cavity of the fixed tube 67 and the rotating cylinder 63 is faster. Due to Bernoulli's principle, the activator in the feeding cylinder 69 is drawn into the fixed tube 67, so that the activator can be fully mixed with the air, thereby maintaining a high activation performance when the mixed gas comes into contact with the coconut shell powder.

[0027] Please refer to the attached instruction manual. Figures 3-4 The activation chamber 1 is equipped with a shovel assembly 7. The shovel assembly 7 includes an arc-shaped groove 71, which is formed on the arc-shaped inner surface of the activation chamber 1. An air guide pipe 72 is fixedly installed on the arc-shaped outer wall of the rotating cylinder 63. A shovel plate 73 is fixedly installed at the end of the air guide pipe 72 away from the rotating cylinder 63. An arc-shaped plate 74 is fixedly installed on the outer wall of the shovel plate 73 near the center of the activation chamber 1. Small air holes 75 are formed on the arc-shaped outer wall of the end of the air guide pipe 72 near the shovel plate 73.

[0028] In this embodiment of the invention, the arc-shaped groove 71 is arranged with a low center and high ends, meaning the interior of the activation chamber 1 is wider in the center and narrower at both ends. The surface of the shovel plate 73 away from the air guide pipe 72 is adapted to the shape of the arc-shaped groove 71, so that when the rotating drum 63 rotates, it can work with the shovel plate 73 to scoop up the coconut shell powder from the arc-shaped groove 71, aiding in its dispersion. Furthermore, the air guide pipe 72 is located at the vertical central axis of the activation chamber 1, and its internal cavity is connected to the interior of the rotating drum 63. Multiple sets of small air holes 75 are provided, and these multiple sets of small air holes 75 are evenly distributed on the arc-shaped outer wall of the air guide pipe 72. Specifically, multiple sets of arc-shaped plates 74 are provided. The arc-shaped plates 74 are mirror images of the air guide pipe 72 on the left and right sides, and the top of the arc-shaped plates 74 is inclined towards the center of the activation chamber 1. The inclination angle of the multiple sets of arc-shaped plates 74 increases as the distance between them and the air guide pipe 72 increases. As a result, when the air guide pipe 72 drives the shovel plate 73 to rotate, the shovel plate 73 shovels up the coconut shell powder at the arc-shaped groove 71. Then, the activator-air mixture blown out by the air guide pipe 72 can work with the arc-shaped plates 74 with different inclination angles to blow the coconut shell powder and the mixture into the gap between the spiral plates 65, thereby further improving the contact efficiency between the coconut shell powder and the activator-air mixture, thus improving the activation efficiency of the coconut shell.

[0029] In this invention, when in use, coconut shell raw material is fed into the crushing chamber 2 through the feed inlet 3. At this time, the drive motor 4 is started to control the crushing mechanism 5 to start, thereby fully crushing the coconut shells entering the crushing chamber 2, processing them into powder that falls into the activation chamber 1. At this time, the servo motor 61 and the air pump 68 are started, and the activator and air mixture entering the rotating drum 63 can be blown into the activation chamber 1 through the air blowing port 661. And guided by the surface of the spiral blade 65, the airflow entering the activation chamber 1 moves in a spiral shape towards the center of the activation chamber 1, thereby dispersing the activator and air mixture into various areas, so as to fully contact the coconut shell powder, thereby ensuring the activation effect of the coconut shell powder, and thus ensuring the processing effect of the activated carbon prepared by the coconut shell powder.

[0030] 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.
