Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to a rapid coal drying device. Background Technology
[0002] Currently, coal dryers generally use gear transmission systems to drive the drum rotation. While this transmission method is widely used, it has some drawbacks in practical operation:
[0003] Gear wear problem: During long-term operation, gears are prone to wear due to continuous meshing, especially under heavy loads and high-speed operation. Gear wear not only reduces transmission efficiency but may also lead to equipment failure and downtime.
[0004] Noise and vibration: Gear transmission systems often generate significant noise and vibration during operation, which not only affects the working environment but may also damage the structural integrity of the equipment.
[0005] High maintenance costs: Due to gear wear and potential failure risks, regular maintenance and replacement are required, which increases the maintenance costs of the equipment.
[0006] In view of the above-mentioned defects of gear transmission, this utility model patent proposes an improved drum rotation drive mechanism for a coal rapid dryer. Utility Model Content
[0007] To address the aforementioned problems, this invention presents a rapid coal drying device.
[0008] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:
[0009] A rapid coal drying device includes a motor, the output end of which is locked to a drive shaft via a coupling, a lead screw on the right end wall of the drive shaft, an interference fit cylinder on the outer wall of the drive shaft, a baffle on the left side wall of the cylinder, multiple sliding grooves on the outer wall of the cylinder, a hollow wheel movably sleeved on the outer wall of the cylinder, multiple sliders on the inner wall of the hollow wheel, multiple protrusions on the outer wall of the hollow wheel, a nut threaded onto the outer wall of the lead screw, and a fixing plate on the left end wall of the nut.
[0010] It also includes a ring, on the inner wall of which are provided multiple fixing seats.
[0011] Furthermore, the grooves are arranged in a circumferentially spaced pattern on the outer wall surface of the cylinder.
[0012] Furthermore, the number of sliders and grooves are equal, and the sliders are slidably embedded within the grooves.
[0013] Furthermore, the width of the ring is smaller than that of the cylinder.
[0014] Furthermore, multiple fixing seats are equally spaced on the inner wall of the ring.
[0015] The beneficial effects of this utility model are:
[0016] This utility model adopts a novel drive mechanism. Compared with the traditional gear transmission method, this drive mechanism reduces mechanical wear between components through special structural design and material selection, thereby reducing maintenance costs and simplifying the maintenance process. The new drive mechanism has a relatively simple structure and is easy to install and disassemble. During maintenance, maintenance personnel can more easily inspect, repair and replace parts. Due to the reduced mechanical wear, the frequency of maintenance is also reduced accordingly, saving manpower, material resources and time costs, and improving the availability and reliability of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] See Figure 1-2As shown, a rapid coal drying device includes a motor 1, a drive shaft 2 locked to the output end of the motor 1 via a coupling, a lead screw 3 on the right end wall of the drive shaft 2, a cylinder 4 with an interference fit on the outer wall of the drive shaft 2, a baffle 5 on the left side wall of the cylinder 4, multiple sliding grooves 6 on the outer wall of the cylinder 4, the sliding grooves 6 being arranged in a circumferential gap on the outer wall of the cylinder 4, a hollow wheel 7 movably sleeved on the outer wall of the cylinder 4, multiple sliders 8 on the inner wall of the hollow wheel 7, multiple protrusions 9 on the outer wall of the hollow wheel 7, a nut 10 threadedly locked to the outer wall of the lead screw 3, and a fixing plate 11 on the left end wall of the nut 10.
[0024] It also includes a ring 12, on the inner wall of which are provided multiple fixing seats 13.
[0025] Furthermore, the number of sliders 8 and the number of grooves 6 are equal, and the sliders 8 are slidably embedded in the grooves 6. When the sliders 8 are slid into the corresponding grooves 6, the sliders 8 limit the hollow wheel 7, so that the hollow wheel 7 rotates synchronously with the moving cylinder 4.
[0026] Furthermore, the width of the ring 12 is smaller than that of the cylinder 4. The motor 1 drives the drive shaft 2 to rotate the cylinder 4, the hollow wheel 7, and the protrusion 9, etc. The hollow wheel 7 and the protrusion 9 facilitate the drive of the ring 12 to rotate the dryer drum.
[0027] Furthermore, multiple fixing seats 13 are equally spaced on the inner wall of the ring 12, and the ring 12 is installed on the outer wall of the dryer drum by welding or bolting through the fixing seats 13.
[0028] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.
[0029] One specific application of this embodiment is:
[0030] In use, the ring 12 is installed on the outer wall of the dryer drum by welding or bolting through the fixing seat 13. The outer wall of the ring 12 is rough to increase the frictional resistance when in contact with the protrusion 9. The motor 1 is installed on the dryer base. The hollow wheel 7, slider 8 and protrusion 9 are made of rubber. The hollow wheel 7 drives the slider 8 and protrusion 9 to move from right to left to the outer wall of the cylinder 4. The slider 8 slides into the corresponding groove 6. The slider 8 limits the hollow wheel 7, so that the hollow wheel 7 rotates synchronously with the cylinder 4. The nut 10 and fixing plate 11 are rotated and fixed on the outer wall of the lead screw 3. The right end of the hollow wheel 7 is fixed by the fixing plate 11. The motor 1 drives the drive shaft 2 to drive the cylinder 4, hollow wheel 7 and protrusion 9 to rotate. The hollow wheel 7 and protrusion 9 drive the ring 12 to drive the dryer drum to rotate. The hollow wheel 7 will wear after a period of use. It can be replaced periodically to reduce maintenance costs.
