Description

Technical Field

[0001] The invention belongs to the technical field of raw material mixing, and in particular relates to an activated carbon raw material mixing device with good mixing effect. Background Art

[0002] Activated carbon is a common adsorption material. It is prepared by pyrolysis and activation of carbon-containing raw materials such as wood, coal and petroleum coke. Activated carbon has a developed pore structure, a large specific surface area and rich surface chemical groups. It is a general term for carbon materials with strong specific adsorption capacity. When producing activated carbon, the raw materials need to be mixed.

[0003] A Chinese patent (CN109395634A) discloses a mixing device for producing phosphoric acid from activated carbon, comprising a base, with support frames fixedly mounted on both sides of the top of the base. The tops of the two support frames are fixedly connected to both sides of the bottom of a mixing drum. A feed port is provided on one side of the top of the mixing drum, a feed hopper is fixedly mounted on one side of the feed port, and a liquid inlet is provided on the other side of the top of the mixing drum, with a liquid inlet pipe inserted into the liquid inlet. The activated carbon production phosphoric acid mixing device drives the rotating shaft to rotate through the installed driving motor, so that the activated carbon and phosphoric acid inside the mixing drum are fully mixed; the installed air pump is used to ventilate when the activated carbon and phosphoric acid are mixed to avoid activated carbon precipitation and influence on the mixing effect; the installed nozzle is used to facilitate the thorough cleaning of the mixing drum and the rotating shaft after mixing to avoid the mixture of activated carbon and phosphoric acid remaining on the inner wall of the mixing drum and the surface of the rotating shaft. The mixing structure set in the current activated carbon production mixing equipment is relatively conventional, and the offset mixing of raw materials cannot be achieved. The mixing effect and the comprehensiveness of the mixing cannot be guaranteed. The overall mixing structure is often subject to large resistance during rotation, which is a damage to both the driving structure and the mixing structure itself, resulting in the traditional mixing structure generally having a short service life and poor use effect. In order to effectively solve the above problems, an activated carbon raw material mixing device with good mixing effect is urgently needed. Summary of the Invention

[0006] As a further description of the above technical solution: The mixing assembly includes a reciprocating threaded sleeve, which is threadedly mounted on the outside of the reciprocating screw. A rotating hole is provided inside the reciprocating threaded sleeve, and a mounting shaft is rotatably mounted in the rotating hole.

[0007] As a further description of the above technical solution: An external gear and a mixing blade are fixedly mounted on the outside of the mounting shaft, and an internal rack is fixedly mounted longitudinally on the top surface of the top shell. The internal rack and the external gear are meshed and connected with each other.

[0009] As a further description of the above technical solution: An expansion component is slidably installed inside the bottom slide groove, and the expansion component includes a mounting longitudinal axis and an expansion inner plate. The mounting longitudinal axis is longitudinally fixedly installed inside the receiving barrel, and an outer spring is sleeved on the outside of the mounting longitudinal axis. A worm is slidably installed on the outside of the mounting longitudinal axis, and the bottom end of the outer spring is fixedly connected to the top end of the worm.

[0010] As a further description of the above technical solution: The expansion inner plate is slidably installed inside the bottom slide groove. A groove is provided on the top surface of the expansion inner plate. An inlaid magnetic plate is inlaid in the groove. A threaded shaft is installed on the internal thread of the inlaid magnetic plate. The threaded shaft has a bidirectional thread.

The bottom magnetic ring has the same magnetic pole as the embedded magnetic plate, and a conical sealing head is fixedly installed on the top end of the sliding shaft. The conical sealing head is located directly below the feed pipe, and the bottom diameter of the conical sealing head is consistent with the inner diameter of the feed pipe.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, a turning component is provided inside. When the raw materials are mixed, the raw materials are placed in the receiving mechanism through the feeding pipe, the motor is turned on, the motor drives the reciprocating screw to rotate, and the telescopic shaft rotates synchronously with the threaded turner. Since the threaded turner is provided with two opposite spiral blades, when the activated carbon raw materials are mixed, the upper and lower sets of spiral blades produce opposite forces to achieve counter-mixing, which greatly improves the raw material mixing effect. At the same time, the threaded turner can also guide the raw materials upward while mixing, and a plurality of material holes are provided on the threaded turner. During the mixing process, the raw materials can flow through the material holes, which can avoid the situation where the viscosity of the activated carbon raw materials increases during mixing and the threaded turner is damaged due to excessive resistance. The spiral turner is steadily improved. The service life of the threaded turner is prolonged. At the same time, when the material pressure drops in the receiving mechanism, the telescopic shaft and the threaded turner can be synchronously lowered under the action of the built-in spring to achieve comprehensive mixing of the raw materials, with good use effect. At the same time, a mixing component is arranged inside, and the reciprocating threaded sleeve on it can be driven to move up and down during the rotation of the reciprocating screw, so that the mounting shaft can be synchronously reciprocated up and down. During this process, the external gear can mesh with the internal rack, thereby driving the mounting shaft to rotate, and the mixing blades rotate synchronously to mix the production raw materials. Through this design, the turning component can be operated while achieving a synchronous linkage mixing effect for raw materials at different positions in the equipment. At the same time, the raw materials guided on the threaded turner are mixed, which further improves the raw material mixing effect in the equipment.

[0014] 2. In the present invention, by arranging a material receiving mechanism and a blocking component inside, during the process of feeding into the material receiving mechanism, the pressure inside the material receiving mechanism will gradually increase. When the pressure inside the material receiving cylinder exceeds the bearing pressure of the pressure-bearing spring shaft, the material receiving cylinder will slowly descend. During the descent of the material receiving cylinder, the worm of the expansion component will gradually contact and press the inner contact piece, and the squeezed worm will move upward. Since the worm and the worm gear sleeve are meshed with each other, the worm can drive the threaded shaft with the worm gear sleeve to rotate. Since the threaded shaft has a bidirectional thread, when the threaded shaft rotates, the two expansion inner plates on it can be synchronously transmitted to the outside, and the expansion inner plates will be positioned. Move to the bottom of the sealing component, and the embedded magnetic plate on the expanded inner plate is now located directly below the bottom magnetic ring at the bottom of the sliding shaft. Since the magnetic poles of the bottom magnetic ring and the embedded magnetic plate are the same, the embedded magnetic plate can generate a strong repulsive force on the bottom magnetic ring, thereby driving the sliding shaft with the bottom magnetic ring to move upward, and the conical sealing head can automatically enter the feed pipe to seal the feed pipe. Through this design, the pressure change after the raw materials are added can be used to automatically control the sealing of the feed pipe without manual control. At the same time, it can ensure the sealing effect in the equipment during the processing after adding materials, thereby improving the mixing effect of the activated carbon raw materials, avoiding external impurities from entering the equipment, and having a good use effect.

[0030] The specific implementation method is as follows: during the feeding process into the material receiving mechanism 9, the pressure in the material receiving mechanism 9 will gradually increase. When the pressure in the material receiving cylinder 91 exceeds the bearing pressure of the pressure-bearing spring shaft 93, the material receiving cylinder 91 will slowly descend. During the descent of the material receiving cylinder 91, the worm 945 of the expansion component 94 will gradually contact and press the inner contact piece 11.

During the descending process of the receiving barrel 91, the worm 945 of the expansion component 94 will gradually contact and press the inner contact piece 11, and the squeezed worm 945 will move upward. Since the worm 945 and the worm gear sleeve 943 are meshed with each other, the worm 945 can drive the threaded shaft 944 with the worm gear sleeve 943 to rotate. Since the threaded shaft 944 has a bidirectional thread, when the threaded shaft 944 rotates, the two threads on it can be screwed together. The expansion inner plate 946 is synchronously conducted outward, and the expansion inner plate 946 will be displaced to the bottom of the sealing component 10. The embedded magnetic plate 947 on the expansion inner plate 946 is now located directly below the bottom magnetic ring 105 at the bottom of the sliding shaft 102. Since the bottom magnetic ring 105 and the embedded magnetic plate 947 have the same magnetic pole, the embedded magnetic plate 947 can generate a strong repulsive force on the bottom magnetic ring 105, thereby driving the sliding shaft 102 with the bottom magnetic ring 105 to move upward, and the conical sealing head 101 can automatically enter the feed pipe 2 to seal the feed pipe 2 to prevent external impurities from entering the equipment.
