Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon processing, in particular to a heating furnace for activated carbon production. Background Art

[0002] Activated carbon, also known as activated black carbon, is a porous carbonaceous material with a very high specific surface area and strong adsorption capacity. It is widely used in water treatment, air purification, medicine, chemical industry, food and beverage industries, etc. The heating of activated carbon usually refers to the activation process of activated carbon, which is a key step for improving the adsorption capacity of activated carbon. The heating of activated carbon aims to improve the pore structure of activated carbon, increase its specific surface area and pore volume, thereby significantly enhancing its ability to remove impurities in water and air.

[0003] The patent with the publication number of CN216141266U discloses a heating furnace on an activated carbon production line. Although this device solves the problems of limited capacity and the need to stop the machine to replenish raw materials every time when heating activated carbon, however, it mainly heats through built-in heating strips, resulting in insufficient heating degree. Moreover, since the activated carbon only falls by gravity, the time passing through the heating area is too short, so that the heating time is insufficient, which is not conducive to the optimization of the pore structure of activated carbon. In view of this problem, this device provides a heating furnace for activated carbon production, aiming to enhance the heating effect and extend the heating time to improve the efficiency of activated carbon in removing impurities in water and air. Summary of the Utility Model

[0004] In order to overcome the shortcomings of too short heating time and insufficient heating degree, the purpose of the utility model is to provide a heating furnace for activated carbon production.

[0005] The technical solution is as follows: An activated carbon production heating furnace includes a base, a circular baffle, a circular cover plate, a support frame, a hopper, a feed pipe, a spiral pipe, a cylinder, a circular plate, a hot air blower, an air duct, a spiral discharge plate, and a driving mechanism. A circular baffle is fixedly installed above the base, and a circular cover plate is fixedly connected to the top of the circular baffle. A through hole is opened on one side of the circular cover plate, and a support frame is fixedly connected to the center of the upper end of the circular cover plate. The top end of the support frame is fixedly connected to a hopper. The bottom of the hopper is rotatably connected to a feed pipe, and the bottom of the feed pipe is fixedly connected to a spiral pipe. A plurality of hot air holes are opened at the upper end of the spiral pipe. A cylinder is arranged outside the spiral pipe, and the cylinder wraps the spiral pipe. An outlet groove is opened on the side of the cylinder, and the outlet groove of the cylinder is welded to the outlet of the spiral pipe. The upper end of the cylinder is rotatably connected to a circular plate. A through hole is opened on one side of the circular plate, and the through hole of the circular plate is aligned with the through hole of the circular cover plate up and down. A hot air blower is fixedly installed at the upper end of the outer side of the circular baffle. The air outlet of the hot air blower is connected to one end of the air duct, and the other end of the air duct is inserted into the through hole of the circular plate through the through hole of the circular cover plate. A spiral discharge plate is arranged on the inner wall of the circular baffle. The spiral discharge plate is located outside the cylinder. A driving mechanism is installed on the circular baffle, and the driving mechanism is used to drive the feed pipe, the spiral pipe, and the cylinder to rotate.

[0006] As a further preferred solution, it further includes a rotating motor and a belt. The rotating motor is fixedly installed at the upper end of the outer side of the circular baffle. Belt pulleys are connected to both the rotating motor and the feed pipe, and the belt is connected between the two belt pulleys.

[0007] As a further preferred solution, a heating plate is arranged on the upper surface of the spiral discharge plate.

[0008] As a further preferred solution, air guide holes are arranged at the upper end of the cylinder.

[0009] As a further preferred solution, it further includes a collection bucket. The collection bucket is placed on the base and is located below the circular baffle.

[0010] As a further preferred solution, a 1 mm gap is provided between the inner side surface of the spiral discharge plate and the outer side of the cylinder.

[0011] The present utility model has the following advantages: The activated carbon will first undergo a preliminary heating with precise temperature control in the spiral pipe. Subsequently, when the activated carbon moves along the spiral discharge plate, it will be secondarily heated by the heating plate on the spiral discharge plate. This dual heating not only significantly improves the heating efficiency of the activated carbon, but more importantly, it effectively extends the total duration of the activated carbon being heated.

[0018] An activated carbon production heating furnace, as Figures 1-4As shown in the figure, it includes a base 1, a circular ring baffle 2, a circular ring cover plate 21, a support frame 3, a hopper 4, a material guide pipe 5, a spiral pipe 6, a cylinder body 8, a circular ring plate 10, a hot air blower 11, an air guide pipe 12, a spiral discharge plate 16 and a driving mechanism. Above the base 1, a circular ring baffle 2 is fixedly installed. At the top of the circular ring baffle 2, a circular ring cover plate 21 is fixedly connected. On one side of the circular ring cover plate 21, a through hole is opened, and the air guide pipe 12 can pass through the through hole. At the center of the upper end of the circular ring cover plate 21, a support frame 3 is fixedly connected. Five square grooves are evenly distributed around the side wall of the support frame 3. At the top of the support frame 3, a hopper 4 is fixedly connected. The bottom of the hopper 4 is rotatably connected with a material guide pipe 5. The bottom of the material guide pipe 5 is fixedly connected with a spiral pipe 6. A number of hot air holes 7 are opened at the upper end of the spiral pipe 6, and the hot air holes 7 are evenly distributed at the upper end of the spiral pipe 6, so that the inside of the spiral pipe 6 can be filled with hot air without dead corners. Outside the spiral pipe 6, there is a cylinder body 8, and the cylinder body 8 wraps the spiral pipe 6. On the side of the cylinder body 8, a discharge chute is opened, and the size of the discharge chute is the same as that of the discharge port 9 of the spiral pipe 6. The discharge chute of the cylinder body 8 is welded to the discharge port 9 of the spiral pipe 6. At the upper end of the cylinder body 8, a gas guide hole 13 is provided, so that gas can be more conveniently introduced into the cylinder body 8. The upper end of the cylinder body 8 is rotatably connected with a circular ring plate 10. On one side of the circular ring plate 10, a through hole is opened, and the through hole of the circular ring plate 10 is aligned with the through hole of the circular ring cover plate 21 up and down. At the upper end of the outer side of the circular ring baffle 2, a hot air blower 11 is fixedly installed. The air outlet of the hot air blower 11 is connected to one end of the air guide pipe 12. The other end of the air guide pipe 12 is inserted into the through hole of the circular ring plate 10 through the through hole of the circular ring cover plate 21. The hot air of the hot air blower 11 flows into the inside of the cylinder body 8 through the air guide pipe 12. Then, the hot air penetrates through the hot air holes 7 on the spiral pipe 6 and permeates into the inside of the spiral pipe 6. When the inside of the spiral pipe 6 is filled with hot air, the preheating is completed. And on the inner wall of the circular ring baffle 2, there is also a spiral discharge plate 16. The spiral discharge plate 16 is located outside the cylinder body 8. There is a 1mm gap between the inner side surface of the spiral discharge plate 16 and the outer side of the cylinder body 8. A heating plate is arranged on the upper surface of the spiral discharge plate 16. A driving mechanism is installed on the circular ring baffle 2, and the driving mechanism is used to drive the material guide pipe 5, the spiral pipe 6 and the cylinder body 8 to rotate. Pour the activated carbon into the hopper 4, and the activated carbon will fall into the spiral pipe 6 along the material guide pipe 5. Under the action of the centrifugal force of the spiral pipe 6, the activated carbon rotates along the guide of the spiral pipe 6. At this time, the hot air filled inside the spiral pipe 6 will improve the pore structure of the activated carbon, thereby increasing the specific surface area and pore volume of the activated carbon. Then, the activated carbon is discharged from the discharge chute of the cylinder body 8 and falls onto the spiral discharge plate 16. Under the influence of gravity and other acting forces, the activated carbon will roll downward spirally along the spiral discharge plate 16. At the same time, a heating plate is laid on the upper surface of the spiral discharge plate 16, which will heat the activated carbon for the second time.

[0019] As Figure 3As shown in the figure, the driving mechanism includes a rotary motor 14 and a belt 15. The rotary motor 14 is fixedly installed at the upper end outside the circular ring baffle 2. Belt pulleys are connected to both the rotary motor 14 and the material guiding pipe 5, and the belt 15 is connected between the two belt pulleys.

[0020] As Figure 1 shown in the figure, it further includes a collection bucket 17. The collection bucket 17 is placed on the base 1 and is located below the circular ring baffle 2. The activated carbon that rolls down from the spiral discharge plate 16 is finally collected in the collection bucket 17 below.
