Description

Technical Field

[0001] This utility model relates to the field of coal production technology, specifically to a fire-resistant drying device for coal production. Background Technology

[0002] Coal is a solid combustible mineral formed gradually from ancient plants buried underground through complex biochemical and physicochemical changes. It is the most abundant and widely distributed fossil fuel on Earth. The main elements constituting the organic matter of coal are carbon, hydrogen, oxygen, nitrogen, and sulfur, with trace amounts of phosphorus, fluorine, chlorine, and arsenic. During the coal production process, drying is necessary.

[0003] According to the fire-resistant drying device for coal production disclosed in patent number CN 221781059 U, during the coal drying process, the coal is first transported to the main body by a conveyor belt. During the process of the coal falling into the main body, the coal is dried by blowing air through the main body. The dried coal is located in a collection box, which is manually pulled out to collect the coal. However, the existing device only blows air through the coal during the process of the coal falling into the main body, and then the coal falls directly into the collection box. The blowing time is short, the drying effect of the coal is poor, and the collection box needs to be pulled out frequently to collect the coal, which is cumbersome. The coal drying needs to be stopped during the coal collection process, which makes the coal drying efficiency low. Therefore, we propose a fire-resistant drying device for coal production.

Detailed Implementation

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a fire-resistant drying device for coal production, including a drying box 1, a support shaft 3 rotatably connected between the top ends of the two corresponding inner walls of the drying box 1, and a material feeding plate 4 with ventilated holes is equidistantly arranged on the outer side of the support shaft 3.

[0024] It should be noted that the material feeding plate 4 with ventilation holes is provided so that the material feeding plate 4 has a good ventilation effect, so that the air can be located between each material feeding plate 4, thereby achieving high-efficiency drying of coal. The material feeding plate 4 can rotate with the rotation of the support shaft 3, and the coal is fed upward during the rotation, so that the air can come into contact with the coal over a large area, thereby achieving rapid drying of coal.

[0025] Please see Figure 1 The top of the material feeding plate 4 is symmetrically installed on the blower 5, and the blower 5 is set to face the support shaft 3. Inside the drying box 1, below the support shaft 3, there is an adjustable arc-shaped support plate 7. The bottom of the arc-shaped support plate 7 is provided with a feeding cylinder 9, and the feeding cylinder 9 is provided with a sliding and adjustable sealing plate 10.

[0026] It should be noted that a heating wire is installed inside the material feeding plate 4 to heat the material feeding plate 4. The heated material feeding plate 4 comes into contact with the coal and can heat the coal to a certain extent. The heated material feeding plate 4 rotates through the support shaft 3, which can continuously turn the coal and increase the contact area between the coal and the air. The air blown out by the fan 5 can effectively remove the moisture in the coal and speed up the drying process. The end of the material feeding plate 4 slides inside the arc-shaped support plate 7, which can lift the coal inside the arc-shaped support plate 7 and dry the coal better.

[0027] Please see Figure 1 and Figure 3 The bottom of the feeding cylinder 9 is integrally provided with a storage pipe 11, and a spiral feeding rod 12 is rotatably connected inside the storage pipe 11. A rotating motor 13 is fixedly installed at the end of the storage pipe 11, and the output shaft end of the rotating motor 13 extends into the storage pipe 11 and is fixedly connected to the central shaft of the spiral feeding rod 12. A discharge port 14 is provided at the end of the storage pipe 11 away from the rotating motor 13.

[0028] Please see Figure 1 A mounting plate 15 is fixedly installed at one end of the bottom of the drying oven 1, and an electric telescopic rod 16 is fixedly installed on the side wall of the mounting plate 15. The piston rod end of the electric telescopic rod 16 passes through the mounting plate 15 and is fixedly connected to the sealing plate 10. The feeding cylinder 9 has a rectangular structure, and a sliding groove is opened at the top of the feeding cylinder 9. The sealing plate 10 is slidably connected in the sliding groove.

[0029] It should be noted that, in use, the hydraulic cylinder 8 raises the arc-shaped support plate 7 to the material feeding plate 4. The end of the material feeding plate 4 slides within the arc-shaped support plate 7, allowing the coal to be dried to be transported by the feeder to the drying chamber 1 through the feed port 2. The coal inside the drying chamber 1 is placed between the material feeding plates 4 on the outside of the support shaft 3. The control system of the device controls the drive motor 6 to drive the support shaft 3 to rotate, and the material feeding plates 4 rotate with the support shaft 3. At the same time, the fan 5 works to blow air and dry the coal being fed. A heating wire is also installed inside the material feeding plate 4 to give the material feeding plate 4 a certain temperature, which heats the coal being fed, removes moisture from the coal, and speeds up the drying process. After drying, the electric telescopic rod 16 is controlled to work. The piston rod of the electric telescopic rod 16 retracts, pulling the sealing plate 10 out of the feed cylinder 9. The coal is placed in the storage pipe 11 under the action of gravity. At this time, the rotating motor 13 works to transport the coal inside the storage pipe 11 to the discharge port 14 and discharge it for collection.

[0030] Please see Figure 1 The mounting plate 15 is symmetrically fixed with limit rods 17 on one side of the feeding cylinder 9, and the sealing plate 10 is symmetrically opened with limit holes. The two limit rods 17 are slidably connected in the two limit holes respectively.

[0031] It should be noted that the setting of the limiting rod 17 enables the sealing plate 10 to slide smoothly in a directional manner.

[0032] Please see Figure 2 The top of the drying chamber 1 is provided with a feeding port 2, and a drive motor 6 is fixedly installed on the side wall of the drying chamber 1. The output shaft end of the drive motor 6 extends into the drying chamber 1 and is fixedly connected to the rotating motor 13.

[0033] It should be noted that the setting of the feeding port 2 facilitates feeding on the one hand, and facilitates the dissipation of moisture inside the drying chamber 1 on the other hand.

[0034] Please see Figure 1 The bottom of the drying chamber 1 has an opening, and hydraulic cylinders 8 are symmetrically installed on the bottom of the drying chamber 1. The piston rod end of the hydraulic cylinder 8 extends into the drying chamber 1 and is fixedly connected to the arc-shaped support plate 7.

[0035] It should be noted that the hydraulic cylinder 8 can control the lifting and lowering of the arc-shaped support plate 7, so that the arc-shaped support plate 7 is close to the material feeding plate 4, which facilitates the material feeding plate 4 to feed the coal in the arc-shaped support plate 7. When it is necessary to collect the coal, the arc-shaped support plate 7 is controlled to be placed at the bottom of the drying box 1, so that the discharge port 14 is located outside the drying box 1, which facilitates the collection of coal.

[0036] Please see Figure 2 The bottom of the drying oven 1 is symmetrically and fixedly connected with a support frame 18.

[0037] It should be noted that the drying oven 1 is equipped with a support frame 18 and a robust support structure, which ensures the stability of the equipment during long-term operation and avoids damage to the equipment caused by vibration or friction.

[0038] Please see Figure 2 The drying oven 1 has observation windows 19 on both sides.

[0039] It should be noted that observation windows 19 are provided on both sides of the drying oven 1, allowing operators to monitor the drying process in real time and ensure the safe and reliable operation of the equipment.
