Description

Technical Field

[0001] The utility model belongs to the technical field of hard carbon preparation, and in particular relates to a carbon powder drying device for hard carbon preparation. Background Art

[0002] Hard carbon powder is commonly used as a solid fuel in a variety of applications, including home heating, industrial heating, barbecues, and thermal power generation. Due to its high calorific value and low ash content, hard carbon burns efficiently, produces minimal ash, and is suitable for use in various combustion equipment. In the metallurgical industry, hard carbon is used as a reducing agent and carbon source.

[0003] In order to increase the efficiency of carbon powder use, it is usually necessary to dry the carbon powder to remove the moisture inside it and facilitate the full combustion of the carbon powder. To achieve this purpose, some traditional carbon powder drying technologies usually perform a single heating and drying process on the carbon powder. For example, Chinese patent CN207439097U discloses a new belt dryer for drying silicon carbide micropowder, which includes a feeding port, a first drying chamber, a second drying chamber, a third drying chamber, a transition chamber, a cooling chamber, a driving sprocket, a transmission chain, a conveyor belt, and a distributor; a swinging uniform distributor is provided below the feeding port, a driven sprocket is provided at the lower front end of the conveyor belt, and a driving sprocket is provided at the lower rear end, the conveyor belt is driven by a motor to rotate the driving sprocket and the driven sprocket, thereby driving the conveyor belt to achieve a forward and backward circulating motion; the distributor includes a swinging guide trough, a self-lubricating double-hole lead screw nut, an adjustable elastic limiter, a guide rod, a positioning ring, a support, a box, a lead screw, an active bevel gear, and a clutch active part.

[0004] However, in the above scheme and the traditional drying method, during the toner drying process, since the toner contains a certain amount of water, the toner has a high humidity, causing the toner to stick together into lumps. When drying using the traditional method, the interior of the toner lumps cannot be effectively dried, affecting the use of the toner.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0026] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0028] See also Figures 1-6 As shown, the utility model is a carbon powder drying device for preparing hard carbon, including a shell 1, a drying mechanism 2 and a stirring mechanism 3. The front and rear inner walls of the shell 1 are provided with mounting seats 9. The drying mechanism 2 includes a drying bin 21, and the drying bin 21 is fixedly connected between the mounting seats 9. The stirring mechanism 3 includes a main stirring column 31, a stirring expansion plate 32 and an auxiliary stirring column 33. The main stirring column 31 is rotatably connected to the middle of the top wall of the drying bin 21 through a sealed bearing. The upper end of the outer arc surface of the main stirring column 31 is fixedly connected to the stirring expansion plate 32, and the outer ends of the stirring expansion plates 32 are rotatably connected to the auxiliary stirring columns 33.

[0029] The outer surface of the main stirring column 31 is provided with spiral auger blades. When the main stirring column 31 rotates, the spiral auger blades on the surface are driven to rotate, so that the material at the bottom of the drying bin 21 surges upward and the material at the top falls from both sides, realizing the longitudinal flow of the carbon powder. The surface of the auxiliary stirring column 33 is provided with stirring blades.

[0030] The auxiliary stirring column 33 rotates while rotating around the main stirring column 31 under the action of the stirring expansion plate 32, so that the auxiliary stirring column 33 rotates around the main stirring column 31 under the action of the stirring expansion plate 32, and the rotation direction is opposite to the rotation direction of the main stirring column 33, so that the auxiliary stirring column 31 and the stirring blades on its surface stir the carbon powder, and the stirring causes the carbon powder to be scraped in the horizontal direction, while the spiral auger blades on the surface of the main stirring column 31 scrape the carbon powder in the longitudinal direction, so that the carbon powder is scraped synchronously in the longitudinal and transverse directions, so that the carbon powder is subjected to dislocation extrusion in the longitudinal and transverse directions, and the lumpy carbon powder is quickly broken and separated, which is convenient for the drying mechanism 2 to dry the carbon powder, and avoids the problem that the carbon powder agglomerates cannot be effectively dried after the carbon powder contains moisture and sticks into agglomerates, thereby affecting the use of the carbon powder.

[0031] The utility model enhances the drying effect of the carbon powder in the drying bin 21 by the synchronous rotation of the main stirring column 31 and the auxiliary stirring column 33 in different directions. At the same time, the hinge blades and stirring blades on the surfaces of the main stirring column 31 and the auxiliary stirring column 31 are used to scrape the carbon powder in the horizontal and vertical directions, so that the carbon powder is misaligned and squeezed, and the block-shaped carbon powder is quickly broken and separated, which makes it easier for the drying mechanism 2 to dry the carbon powder, and avoids the problem that the carbon powder agglomerates cannot be effectively dried after the carbon powder contains moisture and sticks into agglomerates, thereby affecting the use of the carbon powder.

[0032] In one embodiment, for the control switch group 4 , the control switch group 4 is disposed on the front side of the housing 1 , and an input end of the control switch group 4 is electrically connected to an external power source.

[0033] The control switch group 4 is electrically connected to an external power source. The control switch group 4 is provided with control buttons corresponding to the motor 6, the electric valve 10 and the heating plate 22 and used to control their switches.

[0034] You can quickly turn on the electrical appliances that need to be started, and the operation is simple and labor-saving.

[0035] In addition, in specific applications, when it is necessary to turn on the motor 6 , the electric valve 10 and the heating plate 22 , the staff can control their switches by pressing the corresponding control buttons on the control switch group 4 .

[0036] In one embodiment, for the above-mentioned drying bin 21, a motor 6 is installed on the upper side of the drying bin 21 through a mounting base 5, and the output shaft of the motor 6 is fixedly connected to the upper end face of the main stirring column 31. The input end of the motor 6 is electrically connected to the output end of the control switch group 4, so that after the motor 6 is driven, the output shaft of the motor 6 drives the main stirring column 31 to rotate, thereby stirring the carbon powder during the drying process.

[0037] In one embodiment, the stirring mechanism 3 further includes an inner gear ring 34 and a gear 35. The inner gear ring 34 is fixedly connected to the top wall of the drying chamber 21. The upper ends of the outer arc surfaces of the auxiliary stirring columns 33 are fixedly connected to the gears 35. The gears 35 are meshed with the inner gear ring 34.

[0038] Therefore, when the main stirring column 31 drives the auxiliary stirring column 33 to rotate in a circle with the main stirring column 31 as the center through the stirring expansion plate 32, the gear 35 at the upper end of the auxiliary stirring column 33 engages with the inner ring gear 34. Under the meshing action, the gear 35 drives the auxiliary stirring column 33 to rotate with its own central axis as the center, thereby stirring the carbon powder during the drying process.

[0039] In one embodiment, for the above-mentioned drying mechanism 2, the drying mechanism 2 further includes a heating plate 22 and a feeding pipe 23, the heating plates 22 are respectively mounted on the left and right sides of the outer arc surface of the drying bin 21 by bolts, the input end of the heating plate 22 is electrically connected to the output end of the control switch group 4, and the feeding pipe 23 is provided at the feeding port opened on the front side of the outer arc surface of the drying bin 21. The front end of the feeding pipe 23 passes through the front wall of the shell 1, and the front side of the shell 1 is provided with a feeding bin 101. The front end of the feeding pipe 23 is located inside the feeding bin 101;

[0040] Therefore, after the staff puts the hard carbon powder that needs to be dried into the drying chamber 21 through the feeding port on the upper wall of the feeding bin 101, it enters the interior of the drying chamber 21 through the feeding port at the front end of the feeding tube 23. Then the staff drives the heating plate 22 by controlling the switch group 4. At this time, the heating plate 22 starts to heat the drying chamber 21. The temperature inside the drying chamber 21 increases to dry the carbon powder, thereby facilitating the drying of the carbon powder.

[0041] In addition, in specific applications, the drying chamber 21 is a copper drying chamber 21 with good thermal conductivity.

[0042] In one embodiment, for the above-mentioned feeding tube 23, a guide groove 231 is provided on both the left and right sides of the inner arc surface of the feeding tube 23, and a feeding column 7 is slidably connected between the two guide grooves 231 via a slider 71, and a feeding push plate 8 is provided at the front end of the feeding column 7;

[0043] After the carbon powder falls into the feeding tube 23, the staff pushes the feeding column 7, which in turn drives the feeding push plate 8 to move synchronously, thereby pushing the carbon powder into the drying bin 21, thereby facilitating feeding and closing the drying bin 21 after the carbon powder enters the drying bin 21 to prevent the carbon powder from flowing back during the drying and stirring process.

[0044] In addition, in specific applications, during the movement of the loading column 7, the slider 71 slides in the adjacent guide slot 231 to prevent the loading column 7 from rotating and affecting the loading efficiency.

[0045] In one embodiment, for the above-mentioned electric valve 10, the electric valve 10 is provided at the discharge port opened at the lower end of the drying chamber 21, the input end of the electric valve 10 is electrically connected to the output end of the control switch group 4, and the front inner wall of the housing 1 is provided with a discharge plate 11, and the rear end of the discharge plate 11 extends to the outside of the housing 1 through the discharge port opened on the rear wall of the housing 1, and the discharge plate 11 is located at the lower end of the electric valve 10;

[0046] After the toner is dried, the operator controls the electric valve 10 by controlling the switch group 4. The dried toner in the drying chamber 21 then falls onto the surface of the discharge plate 11, allowing the dried toner to be discharged from the drying device and collected by the operator. Furthermore, in practical applications, the surface of the discharge plate 11 is coated with a ceramic coating. The smooth nature of the ceramic, combined with the tilted arrangement of the discharge plate 11 (higher in front and lower in the back), allows the dried toner to be discharged quickly, preventing accumulation.

[0047] To sum up, with the help of the above-mentioned technical solution of the present invention, after the staff puts the hard carbon powder that needs to be dried into the feeding port on the upper wall of the feeding bin 101, it falls into the feeding tube 23 through the feeding port at the front end of the feeding tube 23. At this time, the staff pushes the feeding column 7, thereby driving the feeding push plate 8 to move synchronously, so that the feeding push plate 8 pushes the carbon powder into the interior of the drying bin 21. Then the staff drives the heating plate 22 by controlling the switch group 4. At this time, the heating plate 22 starts to heat the drying bin 21. The temperature inside the drying bin 21 increases to dry the carbon powder. Then, after the staff controls the motor 6 to drive by controlling the switch group 4, the output shaft of the motor 6 drives the main stirring column 31 to rotate, and then the main stirring column 31 drives the auxiliary stirring column 31 through the stirring expansion plate 32. During the circular rotation of the stirring column 33 with the main stirring column 31 as the center, the gear 35 at the upper end of the auxiliary stirring column 33 engages with the inner gear ring 34. Under the meshing action, the gear 35 drives the auxiliary stirring column 33 to rotate with its own central axis as the center, stirring the carbon powder horizontally and vertically. After the carbon powder is dried, the staff controls the electric valve 10 to open by controlling the switch group 4. At this time, the electric valve 10 of the dried carbon powder inside the drying bin 21 falls on the surface of the discharge plate 11, thereby facilitating the discharge of the carbon powder after drying from the drying device. During the drying process of the carbon powder, the device continuously stirs the carbon powder in the drying process through the stirring mechanism 3, so that the carbon powder in the drying process can be fully stirred, so that the carbon powder can be fully dispersed to achieve more comprehensive drying.

[0048] Through the above technical solution, the utility model enhances the drying effect of the carbon powder in the drying bin 21 by the synchronous rotation of the main stirring column 31 and the auxiliary stirring column 33 in different directions, and at the same time utilizes the hinge blades and stirring blades on the surface of the main stirring column 31 and the auxiliary stirring column 31 to form horizontal and vertical scraping on the carbon powder, so that the carbon powder is staggered and squeezed, and the block-shaped carbon powder is quickly crushed and separated, which facilitates the drying mechanism 2 to dry the carbon powder, and avoids the problem that the carbon powder agglomerates cannot be effectively dried after the carbon powder is stuck into agglomerates due to the moisture content, thereby affecting the use of the carbon powder.
