Description

Technical Field

[0001] The utility model relates to the technical field of pulverized coal storage, and specifically, to a new type of pulverized coal storage bin. Background Technique

[0002] Pulverized coal is a fuel after being mechanically crushed, screened, and dried and ground in a coal pulverizing system, and is composed of coal particles with different sizes and irregular shapes.

[0003] In the existing published technology, the application number is: CN201921200720.7, an explosion-proof pulverized coal bin. The key points of its technical solution are as follows: It includes a pulverized coal bin body and a moisture absorption pipe installed inside the pulverized coal bin body. The pulverized coal bin body includes a feeding part, a main storage part, and a discharging part from top to bottom. The feeding part is in the shape of a bowl with a smaller top and a larger bottom, the main storage part is in the shape of a cylindrical barrel, the discharging part is in the shape of a bowl with a larger top and a smaller bottom, the connecting parts of the main storage part with the feeding part and the discharging part are arc-shaped, the feeding part, the main storage part, and the discharging part are an integral whole, a feeding port is arranged above the feeding part, and a discharging port is arranged below the discharging part, which is suitable for the long-term storage of pulverized coal in industrial fields such as mining and the transportation to the downstream technological process.

[0004] However, the above patent still has certain disadvantages when in use: It lacks heat dissipation measures inside during the storage of pulverized coal, which leads to the heat generated by the accumulation of pulverized coal not being able to be dissipated in time. As the heat accumulates more and more, spontaneous combustion is likely to occur. Moreover, when storing pulverized coal, a large amount of pulverized coal is mostly stored centrally, which causes that when the pulverized coal catches fire spontaneously, it will quickly spread to the surrounding pulverized coal, further aggravating the danger situation, being not conducive to personnel quickly dealing with the danger situation, and having poor safety in use, and the overall use effect is not very ideal.

[0005] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0031] Now, the present utility model will be further described in conjunction with the accompanying drawings and specific implementation manners. As Figures 1-4 shown, a new type of pulverized coal storage bin according to an embodiment of the present utility model includes a storage bin main body 1 and support legs 17. A rotating connection is provided at the bottom end inside the storage bin main body 1 with an adjusting disk 2. A driving shaft 9 is welded at the middle position of the adjusting disk 2. One end of the driving shaft 9 penetrates through one side of the storage bin main body 1 and is connected to a motor 6. A number of heat insulation plates 4 are installed around the outer circumference of the driving shaft 9 at the top position of the adjusting disk 2. Storage cavities 11 and water-cooling cavities 3 are respectively formed between two adjacent heat insulation plates 4. A number of water-cooling pipes 12 are installed around the surface of the bottom end inside the storage cavity 11. A through hole 16 is formed on the surface of the bottom end inside the water-cooling cavity 3. A water injection pipe 18 is welded at the middle position of the bottom of the adjusting disk 2, and the water injection pipe 18 is rotatably connected to the storage bin main body 1. The water injection pipe 18 is connected to the water-cooling pipes 12 and the through hole 16 through pipes respectively.

[0032] In one embodiment, a discharge opening 13 is formed at the middle position of the surface of the bottom end inside the adjusting disk 2. A sealing plate 14 is slidably connected inside the discharge opening 13. One end of the sealing plate 14 penetrates through one side of the discharge opening 13 and is connected to an electric push rod 15 inside the adjusting disk 2. The discharge opening 13 is provided to facilitate the discharge of pulverized coal.

[0033] In one embodiment, a number of temperature measuring probes 10 are evenly installed on the surface of the heat insulation plates 4 inside the storage cavity 11. The heat insulation plates 4 are provided to avoid heat transfer, thereby preventing interference between different storage cavities 11 and improving the storage effect.

[0034] In one embodiment, a feed pipe 5, a motor 6, an alarm 7, and a controller 8 are respectively installed on the top surface of the storage bin main body 1. The alarm 7 is provided for warning when the temperature of the pulverized coal is too high, prompting personnel to perform timely treatment. The controller 8 is provided for controlling the internal structure of the device. Since the types of the controller 8 are diverse and the application technology is mature, and the controller 8 can be easily purchased on the market, no specific details will be elaborated here, and personnel can purchase it according to their needs.

[0035] In one embodiment, a discharge pipe 19 is installed on one side of the bottom of the storage bin main body 1. The discharge pipe 19 is provided for discharging the pulverized coal during use, facilitating subsequent operations.

[0036] In one embodiment, a cavity for installing pipes and a storage battery is provided inside the adjusting disc 2, and the storage battery is electrically connected to the temperature measuring probe 10. The temperature measuring probe 10 is provided for monitoring the temperature of the pulverized coal at different positions, facilitating subsequent timely risk elimination operations. The storage battery is provided for supplying energy to the temperature measuring probe 10 and the electric push rod 15. If battery power supply is not adopted, the storage battery can be removed and power supply can be carried out through wires. The specific type can be adjusted according to requirements.

[0037] In one embodiment, support legs 17 are symmetrically installed on both sides of the bottom of the storage bin main body 1. The device as a whole can be fixed through the support legs 17, facilitating the enhancement of the overall use stability.

[0038] In one embodiment, the water cooling pipes 12 are connected to each other through pipes. The interconnected setting of the water cooling pipes 12 is to ensure that the cooling water can fully flow into the water cooling pipes 12 at different positions, thereby achieving the purpose of absorbing and dissipating the heat generated at different positions of the pulverized coal, avoiding the accumulation of the heat of the pulverized coal and causing spontaneous combustion, and improving the safety of storage.

[0039] Working principle: During actual use, personnel can drive the drive shaft 9 by rotating the motor 6, thereby changing the positions of multiple storage chambers 11 connected thereto, so that the openings at the tops of the unused storage chambers 11 can be moved to the position directly below the feed pipe 5. Then, pulverized coal can be added through the feed pipe 5, and subsequent storage operations can be realized. Then, during storage, cooling water can be intermittently introduced into the interior through the water injection pipe 18 at the bottom. When the cooling water is added, the cooling water will enter the through hole 16 and the water cooling pipe 12 through the pipeline. The cooling water flowing out through the through hole 16 can enter the water cooling chamber 3, and the heat transferred from the surface of the heat insulation plate 4 can be absorbed through the water cooling chamber 3. The cooling water entering the water cooling pipe 12 can absorb the heat generated at different positions of the pulverized coal. Then, after adding the cooling water for a period of time, the water supply can be stopped. At this time, the cooling water that has absorbed the heat can be discharged from the water injection pipe 18, thereby realizing the heat dissipation of the pulverized coal and timely dissipating the heat generated inside the storage chamber 11, avoiding the accumulation of heat causing spontaneous combustion of the pulverized coal, improving the safety during storage. Moreover, the pulverized coal is separately arranged in multiple storage chambers 11 for partitioned storage. In this way, when spontaneous combustion occurs subsequently, the transfer of heat can be effectively avoided, so as to limit the danger to the storage chamber 11 where spontaneous combustion occurs and prevent the surrounding storage chambers 11 from being affected, reducing the mutual interference during operation and improving the overall use effect. And when spontaneous combustion occurs, the temperature measurement probe 10 can detect the abnormal temperature, and then trigger the alarm 7 to emit a sound and light signal, so as to prompt personnel to promptly eliminate the danger and prevent the danger from intensifying. The whole device has the advantages of storage cooling, small storage interference, and high safety.
