Description

Technical Field

[0001] This utility model relates to the field of semi-coke drying technology, specifically to a semi-coke drying device. Background Technology

[0002] Semi-coke, a key raw material in calcium carbide production, is a novel carbon material with a high fixed carbon content. The moisture content of semi-coke is generally around 20%. High moisture content in semi-coke affects the thermal efficiency of the calcium carbide furnace and the quality of the product during calcium carbide production. Therefore, it is necessary to reduce the moisture content of semi-coke by drying it to ensure the stability and efficiency of calcium carbide production. Currently, rotary drum dryers are commonly used in industry to dry semi-coke. Heat exchange is achieved through counter-current contact between the semi-coke and the hot airflow inside the drum, thus enabling rapid drying of the semi-coke.

[0003] Existing technologies have conducted some research on semi-coke drying devices. See patent document application number 202320304460.8, which discloses a semi-coke dewatering device, including a workbench. A left cylindrical frame and a right cylindrical frame are installed on both sides of the workbench via fixed brackets. Annular grooves are formed on the inner walls of both the left and right cylindrical frames. Dewatering cylinders are installed on the left and right cylindrical frames via the annular grooves and ball bearings. A drying mechanism is provided inside the dewatering cylinder. Several sets of gear rings are fitted on the outer wall of the dewatering cylinder, and gear rings are fitted between the sets of gear rings. A motor is installed on the upper end of the workbench. A transmission shaft is installed on the output end of the motor via a coupling. Gears are fitted on the transmission shaft, and the gears mesh with the gear rings.

[0004] Therefore, it can be seen that by installing several sets of gear rings on the dehydration drum to assist in driving the drum's rotation, the transmission stability is improved. However, since the gear rings are connected to the drying drum as a single unit, when repairing or replacing them, all other transmission components along the drying drum's axial direction must first be removed before the gear rings can be moved axially along the drying drum to separate from it, thus achieving disassembly. The disassembly process is time-consuming and labor-intensive, resulting in low maintenance efficiency. Utility Model Content

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] Please refer to Figures 1-3 As shown, this utility model discloses a semi-coke drying device. A first semi-ring toothed plate 9 and a second semi-ring toothed plate 10 are symmetrically distributed on both sides of the central axis of the drying cylinder 4. Both the first semi-ring toothed plate 9 and the second semi-ring toothed plate 10 are engaged with the drying cylinder 4, and the first semi-ring toothed plate 9 and the second semi-ring toothed plate 10 form a toothed ring.

[0027] In this invention, the first half-ring toothed plate 9 and the second half-ring toothed plate 10 are arranged to form a toothed ring, and the first half-ring toothed plate 9 and the second half-ring toothed plate 10 are respectively engaged with the drying cylinder 4. When the toothed ring is inspected or replaced, the first half-ring toothed plate 9 and the second half-ring toothed plate 10 are removed respectively, so that the first half-ring toothed plate 9 and the second half-ring toothed plate 10 are separated from the drying cylinder 4 radially. There is no need to remove other transmission components arranged axially along the drying cylinder 4. The disassembly process of the toothed ring is time-saving and labor-saving, and greatly improves the maintenance efficiency.

[0028] Optionally, the second semi-ring toothed plate 10 has a second connecting end on the side near the first semi-ring toothed plate 9. The second semi-ring toothed plate 10 has two second connecting ends along the circumference of the drying cylinder 4, and each of the two second connecting ends is connected to a docking block 14. The first semi-ring toothed plate 9 has a first connecting end on the side near the second semi-ring toothed plate 10. The first semi-ring toothed plate 9 has two first connecting ends along the circumference of the drying cylinder 4. Each of the two first connecting ends is provided with a docking groove 15 that matches the docking block 14. The docking block 14 engages with the corresponding docking groove 15. The engagement between the docking groove 15 and the docking block 14 facilitates the connection between the first semi-ring toothed plate 9 and the second semi-ring toothed plate 10, making the operation convenient and saving time and effort.

[0029] Optionally, both the docking block 14 and the docking groove 15 have positioning holes 16 at their adjacent ends. A positioning pin 17 passes through the positioning hole 16, and a second fixing nut 18 is connected to one end of the positioning pin 17. The second fixing nut 18 and the positioning pin 17 are detachably connected. The second fixing nut 18 and the positioning pin 17 can be connected by threads or keys. In this embodiment, the positioning pin 17, the second fixing nut 18, and the positioning hole 16 cooperate with each other to position the positioning pin 17 through the positioning hole 16 at the splicing position of the second half-ring toothed plate 10 and the first half-ring toothed plate 9, thereby positioning the splicing position of the second half-ring toothed plate 10 and the first half-ring toothed plate 9.

[0030] Optionally, a set of positioning teeth 11 are symmetrically connected to both sides of the second semi-ring toothed plate 10 along the axial direction of the drying cylinder 4. The positioning teeth 11 are fixedly connected to the second semi-ring toothed plate 10. A positioning gear 12 is sleeved on the positioning pin 17. The positioning gear 12 is located between the second fixing nut 18 and the first semi-ring toothed plate 9, and the positioning gear 12 meshes with the positioning teeth 11. Through the mutual cooperation of the positioning teeth 11, the second fixing nut 18, and the positioning gear 12, the splicing position of the second semi-ring toothed plate 10 and the first semi-ring toothed plate 9 is locked, improving the firmness of the splicing between the second semi-ring toothed plate 10 and the first semi-ring toothed plate 9.

[0031] Reference Figure 3 and Figure 4 As shown, in some embodiments, a clamping ring block 22 is fixedly connected to the outer surface of the drying cylinder 4. Positioning blocks 21 are symmetrically arranged on both sides of the clamping ring block 22 along the axial direction of the drying cylinder 4. Engaging ring grooves 20 are formed on the inner surfaces of the first half-ring toothed plate 9 and the second half-ring toothed plate 10. The engaging ring grooves 20 engage with the clamping ring block 22. Positioning slots 19 are formed on the engaging ring grooves 20, and the positioning slots 19 cooperate with the positioning blocks 21. The engagement of the clamping ring block 22 with the engaging ring groove 20 facilitates the connection between the first half-ring toothed plate 9 and the second half-ring toothed plate 10 and the drying cylinder 4, making operation convenient.

[0032] Optionally, an auxiliary tooth block is connected to one end of the positioning pin 17 near the positioning tooth plate 11. The auxiliary tooth block and the second fixing nut 18 are located on opposite sides of the first half-ring tooth plate 9 along the axial direction, and the auxiliary tooth block meshes with the positioning tooth plate 11. The auxiliary tooth block helps to reduce the friction between the positioning pin 17 and the positioning tooth plate 11 during movement, thereby improving the smoothness of the movement of the positioning pin 17.

[0033] Reference Figure 2 , Figure 3 and Figure 5As shown, in some embodiments, both the first semi-ring toothed plate 9 and the positioning toothed plate 11 have cavities along the axial direction of the drying cylinder 4, with a screw threaded through each cavity. One end of the screw is connected to a third fixing nut 23. Specifically, the cavities on the first semi-ring toothed plate 9 and the positioning toothed plate 11 are coaxially arranged. The screw, the third fixing nut 23, and the cavities cooperate with each other to facilitate the fixing of the positioning toothed plate 11 onto the first semi-ring toothed plate 9.

[0034] Reference Figure 2 and Figure 4 As shown, in some embodiments, the drying cylinder 4 has an open end, and an installation rod 6 is provided inside the drying cylinder 4. Positioning blocks 5 are provided at both ends of the installation rod 6. A groove matching the positioning block 5 is provided on the inner wall of the drying cylinder 4, and the positioning block 5 facing away from the open end is engaged in the groove. The positioning block 5 near the open end is threadedly connected to the installation rod 6. The diameter of the positioning block 5 is larger than the diameter of the installation rod 6 to block components connected to the installation rod 6. One end of the installation rod 6 near the open end passes through the positioning block 5 and is exposed to the positioning block 5. A first fixing nut 13 is sleeved on the end of the installation rod 6 near the open end and abuts against the positioning block 5 to reinforce the position of the positioning block 5.

[0035] In this embodiment, the operator can connect the guide plate used to assist in the turning of the semi-coke to the mounting rod 6, and then snap the positioning block 5 on the mounting rod 6 away from the opening end into the slot, thus realizing the installation of the mounting rod 6 and the guide plate. When disassembling the mounting rod 6, the operator does not need to enter the inner cavity of the drying cylinder 4 to remove the guide plate; the mounting rod 6 can simply be pulled out of the drying cylinder 4. The mounting rod 6, the positioning block 5, and the first fixing nut 13 cooperate with each other, facilitating the assembly and disassembly of the mounting rod 6, making the operation convenient and improving the installation efficiency.

[0036] Reference Figure 1 As shown, in some embodiments, a drive gear 7 meshes below the first semi-ring toothed plate 9, and a motor 8 is coaxially and fixedly connected to the input end of the drive gear 7. A load-bearing ring 3 is provided on both sides of the first semi-ring toothed plate 9 along the axial direction of the drying cylinder 4. The load-bearing ring 3 is connected to the drying cylinder 4, and a load-bearing roller 2 is rotatably connected below the load-bearing ring 3. Support blocks are connected to both ends of the load-bearing roller 2 along the axial direction, and a base plate 1 is fixedly connected to the bottom of the support blocks.

[0037] In this embodiment, when the drying cylinder 4 rotates, the motor 8 drives the drive gear 7 to rotate, and the drive gear 7 drives the gear ring formed by the first half-ring tooth plate 9 and the second half-ring tooth plate 10 to rotate. The rotating gear ring drives the drying cylinder 4 with the inner surface clamp to rotate. When the drying cylinder 4 rotates, the load-bearing ring 3 rotates under the restriction of the load-bearing roller 2.

[0038] The working principle and usage procedure of this device are as follows: During installation, the first half-ring toothed plate 9 is moved to the outside of the drying cylinder 4, so that the snap-fit ​​groove 20 opened on the inner surface of the first half-ring toothed plate 9 engages with the corresponding clamping ring block 22 on the outside of the drying cylinder 4, and the positioning groove 19 on the inner surface of the first half-ring toothed plate 9 engages with the positioning block 21 on the corresponding clamping ring block 22. The second half-ring toothed plate 10 is moved to the outside of the drying cylinder 4 symmetrical to the first half-ring toothed plate 9, so that the snap-fit ​​groove 20 opened on the inner surface of the second half-ring toothed plate 10 engages with the corresponding clamping ring block 22 on the outside of the drying cylinder 4, and the positioning groove 19 on the inner surface of the second half-ring toothed plate 10 engages with the positioning block 21 on the corresponding clamping ring block 22.

[0039] At this time, the docking block 14 on the second half ring tooth plate 10 is engaged in the docking groove 15 on the first half ring tooth plate 9, and the positioning tooth plate 11 on the second half ring tooth plate 10 is engaged in the outer wall of the first half ring tooth plate 9. The cavity opened on the positioning tooth plate 11 is engaged and aligned with the cavity opened on the first half ring tooth plate 9. The screw is passed through the two cavities, and the third fixing nut 23 is sleeved on the screw and pressed against the positioning tooth plate 11, thereby fixing the position of the positioning tooth plate 11 engaged on the first half ring tooth plate 9.

[0040] The positioning pin 17 is passed through the positioning hole 16 opened on the docking slot 15 and the positioning hole opened on the docking block 14, so that the positioning pin 17 passes through the splicing position of the second half ring tooth plate 10 and the first half ring tooth plate 9, and positions the splicing position of the second half ring tooth plate 10 and the first half ring tooth plate 9.

[0041] The positioning gear 12 is fitted onto the positioning pin 17, so that the positioning gear 12 is engaged with the upper surface of the positioning tooth plate 11 and the positioning gear 12 meshes with the positioning tooth plate 11. Then, the second fixing nut 18 is fitted onto the positioning gear 12 and rotated so that the second fixing nut 18 is threadedly connected to the positioning pin 17, thus fixing the position of the positioning gear 12. At this time, the positioning gear 12 engaged on the positioning pin 17 and the auxiliary tooth block fixed on the other side of the positioning pin 17 simultaneously mesh with the positioning tooth plate 11, thereby locking the splicing position of the second half-ring tooth plate 10 and the first half-ring tooth plate 9 and improving the firmness of the splicing of the second half-ring tooth plate 10 and the first half-ring tooth plate 9.
