[0002] Granular decolorizing activated carbon is indispensable in many fields. In the food and beverage industry, it is used for decolorizing and refining liquids such as syrups and juices to improve product color and quality; in the pharmaceutical field, it can remove impurities and pigments in drug solutions to ensure drug quality; in the environmental protection field, it adsorbs colored pollutants in industrial wastewater and waste gas to help purify the environment. However, existing preparation equipment is difficult to meet the growing demand for high-quality and high-efficiency production.

[0003] During the activated carbon forming process, the traditional preparation device cannot accurately control the particle shape and specifications. Irregular particles will lead to uneven filling and reduce adsorption efficiency. Some granulation methods, such as granulation with a granulation disk, condense the activated carbon powder into granules by rotating the disk and adding water. However, this method is prone to large differences in particle size, and powder needs to be added again after each granulation. It is difficult to achieve continuous production, the production efficiency is low, and it cannot meet the requirements of large-scale industrial production. Summary of the invention

[0009] Among them, the feeding assembly includes a first motor, which is fixedly installed at the bottom of the casing through a bracket. After the first motor is powered on, it generates rotational power to drive the entire feeding assembly to work. The output end of the first motor is fixedly connected to a transmission shaft, and the transmission shaft passes through the casing and extends to the inside thereof. The top of the transmission shaft is fixedly connected to a conical rotating rod, and a spiral feeding piece is fixedly installed on the surface of the conical rotating rod.

The accommodating frame tube is arranged inside the fixed tube, and the groove on the surface of the cylindrical cam interacts with the roller, and the reciprocating up and down movement of the accommodating frame tube is controlled by the V-shaped profile of the groove.

[0017] Preferably, a slide rod is fixedly connected to the middle of the bottom of the accommodating frame tube, second slide grooves are opened on both sides of the slide rod, a fixing ring is fixedly installed in the middle of the bottom of the fixed tube, a slide rail is fixedly installed on the inner side of the fixing ring, and the slide rail is slidably installed inside the second slide groove.

[0018] Preferably, a cutter is fixedly connected to the bottom of the slide rod, and the cutter is slidably installed inside the accommodating groove. The auxiliary cover improves the stability of the cutting assembly during cutting and provides a sliding space for the cutter. The cutter cuts the activated carbon strips extruded from the forming cylinder into granules.

[0019] The present invention provides a device for preparing granular decolorized activated carbon. It has the following beneficial effects:

[0020] 1. The granular decolorized activated carbon preparation device, through the setting of the variable pitch spiral feed sheet, the first motor drives the transmission shaft, drives the conical rotating rod and the spiral feed sheet to rotate. The material falls from the feed hopper and quickly enters from the large pitch. This design can quickly accept a large amount of material, ensure the efficient and stable feeding process, avoid the accumulation and blockage of materials at the feed port, and greatly improve the feeding efficiency. As the spiral feed sheet rotates, the material moves to the discharge port, and the pitch gradually decreases during the process, so that the material is subjected to gradually increasing extrusion force during the transportation process. The smaller pitch can squeeze the material more tightly, which not only helps to remove the air inside the material and reduce the gaps inside the particles, but also makes the material particles more tightly combined, which is conducive to subsequent molding and improves the quality of molded particles.

[0021] 2. The granular decolorized activated carbon preparation device is configured by cooperating with a vibration component and a percussion hammer. When the straight rod rotates, the buffer spring expands and contracts in the first slide slot, driving the slide bar and the percussion block to vibrate up and down. The percussion block rises and is squeezed and contacted with the percussion hammer. The coordination of the vibration component and the percussion hammer can effectively prevent the material from being blocked in the feed hopper. During the activated carbon preparation process, the material may easily form blockages such as bridging and agglomeration in the feed hopper due to factors such as humidity, viscosity or uneven particle size. The coordination of the vibration component and the percussion hammer can keep the material in a loose state at all times through the vibration generated by the percussion, so that it can pass through the feed hopper smoothly and enter the subsequent process.

[0022] 3. Through the setting of the discharge component, the material enters the discharge hopper through the discharge port, and then is extruded through the discharge hole of the forming plate and enters the forming cylinder, where it is initially formed with the assistance of the forming cylinder. The setting of the discharge component ensures that each activated carbon strip extruded from the discharge hole has the same basic shape, providing raw materials for subsequent forming and cutting processes. The forming cylinder fixedly mounted on the outer surface of the forming plate further shapes the extruded activated carbon strip. The forming cylinder is connected to the inside of the discharge hopper through the discharge hole. During the material extrusion process, the inner wall of the forming cylinder applies uniform pressure to the activated carbon strip, making its shape more regular and its surface smoother. This setting ensures that the produced granular decolorized activated carbon is uniform in shape.

[0023] Fourth, through the setting of the cutting assembly, the second motor drives the rotating shaft to rotate. As the cylindrical cam rotates, its groove profile pushes the roller, so that the receiving frame tube reciprocates up and down inside the fixed tube. The slide rail slides in the second slide groove to provide guidance for the up and down movement of the slide bar, ensuring that the slide bar can only move stably in the vertical direction. The cutter moves up and down with the slide bar to cut the activated carbon strip into granules. The cutting assembly can accurately cut the activated carbon strips. Accurate cutting ensures the consistency of product size, improves the quality stability of the product, and obtains granular decolorized activated carbon of the required size to meet the requirements of product specifications in different application scenarios.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: a device for preparing granular decolorized activated carbon, comprising:

[0039] A casing 1, a feed hopper 2 is fixedly installed on the top of the casing 1, the feed hopper 2 is used to put raw materials and guide the raw materials to smoothly enter the device for subsequent processing, a hopper door 9 is installed on the top of the feed hopper 2 through a rotating shaft, a handle 10 is fixedly installed on the surface of the hopper door 9, an observation window 8 and a fixed ring frame 6 are fixedly installed on the outer surface of the casing 1, the fixed ring frame 6 is arranged below the observation window 8, and a support leg 7 is fixedly connected to the bottom of the fixed ring frame 6, a percussion hammer 11 is fixedly installed on the inner wall of the feed hopper 2, a material guide strip 12 is fixedly installed on the inner wall of the casing 1, and an air inlet 13 is fixedly installed on the outer surface of the feed hopper 2, and the air inlet 13 is used to introduce external high-pressure gas to assist in the extrusion of raw materials;

[0040] The feeding assembly 3 is installed in the middle of the casing 1. The feeding assembly 3 is used to squeeze the raw materials in the feed hopper 2 and convey them to the discharge end to ensure the orderly flow of the materials in the device;

[0041] The feeding assembly 3 includes a first motor 31, which is fixedly installed at the bottom of the casing 1 through a bracket. When the first motor 31 is powered on, it generates rotational power to drive the entire feeding assembly 3 to work. The output end of the first motor 31 is fixedly connected to a transmission shaft 32, which passes through the casing 1 and extends to the inside thereof. The top of the transmission shaft 32 is fixedly connected to a conical rotating rod 33, and a spiral feeding sheet 34 is fixedly installed on the surface of the conical rotating rod 33. The conical rotating rod 33 rotates under the drive of the transmission shaft 32, and the spiral feeding sheet 34 on its surface rotates accordingly to realize the transportation of materials.

[0042] The spiral conveyor plate 34 is a variable pitch spiral plate, and the pitch of the spiral conveyor plate 34 is large near the feed hopper 2 and gradually becomes smaller toward the discharge end. This design can quickly receive and initially convey a large amount of material falling from the feed hopper 2. The pitch gradually becomes smaller toward the discharge end, which can gradually squeeze the material to make it more compact, which is conducive to subsequent molding.

[0043] A straight rod 35 is fixedly connected to the top of the conical rotating rod 33, and a support frame 36 is rotatably installed on the bottom of the outer surface of the straight rod 35. The frame rod of the support frame 36 is fixedly connected to the inner wall of the casing 1. The support frame 36 improves the stability of the device. A stirring head 38 is fixedly installed on the top of the straight rod 35. The stirring head 38 stirs and breaks up the materials entering the feed hopper 2 to make the materials more evenly mixed and ensure product quality. A vibration component 37 is installed on the outer surface of the straight rod 35. The vibration component 37 prevents the material in the feed hopper 2 from being blocked by vibration.

[0044] The vibration assembly 37 includes a first slide groove 371 , which is provided on the outer surface of the straight rod 35 . A buffer spring 372 is fixedly installed inside the first slide groove 371 . The buffer spring 372 utilizes its own elastic deformation to provide elastic force for the slide bar 373 to vibrate up and down.

[0045] A slide bar 373 is fixedly installed on the top of the buffer spring 372, and a knocking block 374 is fixedly installed on the side of the top of the slide bar 373 away from the buffer spring 372. The knocking block 374 is squeezed and adapted to the knocking hammer 11. During the rotation of the straight rod 35, the buffer spring 372 continuously expands and contracts in the first slide groove 371, driving the slide bar 373 connected to the top to slide up and down in the first slide groove 371, and the knocking block 374 on the top of the slide bar 373 vibrates up and down with the slide bar 373. When the knocking block 374 rises to a certain position, it is squeezed and contacted with the knocking hammer 11 on the inner wall of the feed hopper 2, and the inner wall of the feed hopper 2 is knocked to prevent material from being blocked in the feed hopper 2.

[0046] The second embodiment is based on the first embodiment. Figures 1 to 12 As shown, the discharging assembly 4 is installed at the bottom of the outer surface of the housing 1, and the discharging assembly 4 is used to shape and output the material processed by the feeding assembly 3;

[0047] The discharge assembly 4 includes a discharge hopper 41 and a forming plate 44. The discharge hopper 41 is fixedly mounted on the outer surface of the housing 1. The discharge hopper 41 collects the material flowing out from the discharge end and guides the material to the forming plate 44. A card slot 47 is provided on the inner wall of the discharge hopper 41. A card strip 48 is fixedly connected to the edge of the forming plate 44. The card strip 48 is card-fitted with the card slot 47. The card strip 48 and the card slot 47 are arranged to fix the position of the forming plate 44, so as to facilitate the installation and removal of the forming plate 44.

[0048] A discharge hole 45 is provided on the surface of the forming plate 44, and a forming cylinder 46 is fixedly installed on the outer surface of the forming plate 44. The forming cylinder 46 is connected to the inside of the discharge hopper 41 through the discharge hole 45. The material processed by the feeding assembly 3 enters the discharge hopper 41 of the discharge assembly 4 through the discharge end of the inner wall of the casing 1 under the push of the spiral conveying sheet 34. After the discharge hopper 41 collects the material, it guides the material to flow to the forming plate 44. The forming plate 44 is fixed with the card groove 47 on the inner wall of the discharge hopper 41 through the card strip 48 on the edge. The material is extruded through the discharge hole 45 on the surface of the forming plate 44 to preliminarily form an activated carbon strip of a specific shape. The forming cylinder 46 fixed on the outer surface of the forming plate 44 assists the material in extrusion molding, so that the shape of the extruded activated carbon strip is more regular.

[0049] An auxiliary cover 42 is fixedly mounted on one end of the discharge hopper 41 away from the housing 1, and receiving grooves 43 are provided on the upper and lower sides of the auxiliary cover 42;

[0050] The cutting assembly 5 is installed on the outer surface of the housing 1 and is arranged directly above the discharging assembly 4. The cutting assembly 5 is used to cut the activated carbon strips extruded from the discharging assembly 4 into particles of a desired length.

[0051] The cutting assembly 5 includes a fixed plate 501, a second motor 502 and a receiving frame tube 511. The fixed plate 501 is fixedly mounted on the outer surface of the housing 1. The second motor 502 is fixedly mounted on the top of the fixed plate 501 through a bracket. A fixed tube 505 is fixedly mounted on the bottom of the fixed plate 501. The output end of the second motor 502 is fixedly connected to a rotating shaft 509. The rotating shaft 509 passes through the middle of the fixed tube 505 and extends to the inside thereof.

[0052] The bottom of the rotating shaft 509 is fixedly connected with a cylindrical cam 510, which is arranged inside the receiving frame tube 511. Rollers 512 are installed inside the groove of the cylindrical cam 510. The rollers 512 are fixedly installed on both sides of the outer surface of the receiving frame tube 511. The rollers 512 penetrate the receiving frame tube 511 and extend to the inner side thereof. The receiving frame tube 511 is arranged inside the fixed tube 505. The groove on the surface of the cylindrical cam 510 interacts with the rollers 512, and the receiving frame tube 511 is controlled to reciprocate up and down through the V-shaped profile of the groove.

[0053] A slide rod 503 is fixedly connected to the middle of the bottom of the accommodating frame tube 511, and second slide grooves 506 are opened on both sides of the slide rod 503. A fixing ring 507 is fixedly installed in the middle of the bottom of the fixed tube 505, and a slide rail 508 is fixedly installed on the inner side of the fixing ring 507. The slide rail 508 is slidably installed inside the second slide groove 506.

[0054] When in use, the operator holds the handle 10 and turns the bucket door 9, which opens around the rotating shaft at the top of the feed hopper 2, pours the raw materials required for preparing granular decolorized activated carbon into the feed hopper 2, and then closes the bucket door 9 to prevent the raw materials from spilling.

[0055] Start the first motor 31, which is fixed to the bottom of the casing 1 through a bracket. The output end of the motor drives the transmission shaft 32 to rotate. The transmission shaft 32 transmits power to the conical rotating rod 33 connected to the top, and the spiral conveying piece 34 on the surface of the conical rotating rod 33 rotates accordingly. Because the pitch is large near the feed hopper 2, a large amount of raw materials falling from the feed hopper 2 can be quickly received and initially conveyed. As the material moves toward the discharge end, the spiral conveying piece 34 gradually becomes smaller in pitch to gradually squeeze the material, making the material more compact.

[0056] At this time, the straight rod 35 at the top of the conical rotating rod 33 rotates under its drive, and the bottom of the outer surface of the straight rod 35 is supported by the support frame 36 to ensure the rotation stability. The stirring head 38 at the top of the straight rod 35 rotates accordingly to stir the material in the conveying process to make the material mixed more evenly.

[0057] During the rotation of the straight rod 35, the buffer spring 372 continuously expands and contracts in the first slide groove 371, driving the slide bar 373 connected to the top to slide up and down in the first slide groove 371, and the knocking block 374 on the top of the slide bar 373 vibrates up and down with the slide bar 373. When the knocking block 374 rises to a certain position, it is squeezed and contacted with the knocking hammer 11 on the inner wall of the feed hopper 2, and the inner wall of the feed hopper 2 is knocked to prevent material from being blocked in the feed hopper 2.

[0058] The material processed by the feeding assembly 3 enters the discharge hopper 41 of the discharge assembly 4 through the discharge end of the inner wall of the casing 1 under the push of the spiral conveying plate 34. After collecting the material, the discharge hopper 41 guides the material to flow to the forming plate 44. The forming plate 44 is fixed with the card groove 47 on the inner wall of the discharge hopper 41 through the card strip 48 on the edge. The material is extruded through the discharge hole 45 on the surface of the forming plate 44 to preliminarily form activated carbon strips of a specific shape. The forming cylinder 46 fixed on the outer surface of the forming plate 44 assists the extrusion of the material to make the extruded activated carbon strips more regular in shape.

[0059] The second motor 502 is started, and the second motor 502 drives the rotating shaft 509 to rotate together with the cylindrical cam 510. Since rollers 512 are installed in the groove of the cylindrical cam 510, and the rollers 512 are fixed on both sides of the outer surface of the accommodating frame tube 511 and penetrate to the inner side, as the cylindrical cam 510 rotates, its groove profile pushes the rollers 512, so that the accommodating frame tube 511 reciprocates up and down inside the fixed tube 505, and the slide rail 508 slides in the second slide groove 506 to provide guidance for the up and down movement of the slide bar 503, ensuring that the slide bar 503 can only move stably in the vertical direction, limiting its movement trajectory, and improving the movement stability. The cutter 504 fixedly connected to the bottom of the slide bar 503 moves up and down with the slide bar 503;

[0060] The activated carbon strips extruded from the forming cylinder 46 enter the receiving groove 43, and when the cutter 504 moves downward, the activated carbon strips are cut into granules. During the cutting process, the auxiliary cover 42 improves the stability of the cutting assembly 5 and provides a sliding space for the cutter 504, ensuring that the cutting action is carried out smoothly and the cutting work of the activated carbon strips is continuously completed.
