Description

Technical Field

[0001] This invention relates to the technical field of coal resource utilization, and in particular to a steam-type thawing chamber for frozen coal. Background Technology

[0002] Due to low winter temperatures, coal transport by train often results in frozen cars, making it difficult to unload them during winter tippers. This not only causes losses for coal companies but also poses a hidden danger to the operation of power plant equipment. In northern my country, the freezing of coal cars in thermal power plants is very serious, but most of them have thawing warehouses or large thawing sheds, or use methods such as coal dehydration to avoid this. In recent years, weather changes have led to more frequent cold waves in the south, and coal cars in power plants in central and southern my country have also frozen.

[0003] Existing power plants lack effective anti-freezing facilities, forcing them to use manual unloading of coal, which is extremely inefficient, costly, and poses safety hazards to unloading personnel and transportation equipment. The main freezing area of ​​frozen coal is the adhesion between the frozen coal and the train car body. When using a thawing chamber to heat frozen coal with steam, steam is generally sprayed onto the outside of the train car body through steam pipes or nozzles. The steam disperses after contacting the train car body, and the heating time between the high-temperature steam and the train car body is short, resulting in long thawing time and high steam consumption. Furthermore, during the thawing process, the adhesion and accumulation of frozen coal to the train car body leads to low thawing efficiency. Summary of the Invention

Simultaneously, the temperature control mechanism activates the power mechanism to operate the vibration mechanism, which vibrates the frozen coal adhering to the train car body to disperse it, increasing the heating area of ​​the frozen coal and improving the thawing efficiency.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagrams.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0031] Example 1

[0032] Reference Figures 1-3A schematic diagram of the overall structure of a steam-type thawing chamber for frozen coal is provided. The steam-type thawing chamber for frozen coal includes a pre-set mechanism 100, including a thawing chamber 101, a pipe assembly 102 disposed in the thawing chamber 101, a plurality of laying grooves 103 disposed in the thawing chamber 101, and a coal car cargo frame 104 disposed in the thawing chamber 101; and a temperature control mechanism 200, including a temperature control box 201 disposed on the thawing chamber 101, and a temperature control component 202 disposed in the temperature control box 201. The laying grooves 103 are provided to facilitate the installation and laying of the pipe assembly 102 and the temperature control box 201.

[0033] Specifically, the pipe assembly 102 includes a main steam delivery pipe 102a disposed in the laying trench 103, a steam input pipe 102b connected to the main steam delivery pipe 102a, and a plurality of branch steam delivery pipes 102c connected to the main steam delivery pipe 102a; the plurality of branch steam delivery pipes 102c are all disposed in the laying trench 103, and the temperature control box 201 is connected to the main steam delivery pipe 102a. The purpose of connecting the temperature control box 201 to the main steam delivery pipe 102a is to facilitate the components of the temperature control box 201 to act on the main steam delivery pipe 102a.

[0034] Furthermore, the temperature control component 202 includes a heat transfer drive component 202a disposed in the temperature control box 201, a trigger component 202b disposed in the temperature control box 201, and a flow-closing component 202c disposed in the temperature control box 201. The trigger component 202b is used to start the operation of subsequent components after the temperature reaches the predetermined temperature, while the flow-closing component 202c is used to prevent steam from continuing to fill the pipe assembly 102 when the temperature in the thawing chamber 101 is sufficient, which can effectively save steam and avoid resource waste.

[0035] Furthermore, the heat transfer drive component 202a includes a gas-sensing piston 202a-1 disposed within the temperature control box 201, a superconducting heat transfer tube 202a-2 disposed on the gas-sensing piston 202a-1, and a first piston rod 202a-3 and a second piston rod 202a-4 disposed on the gas-sensing piston 202a-1. The superconducting heat transfer tube 202a-2 is in contact with the coal car cargo frame 104. The gas-sensing piston 202a-1 is injected with real gases such as nitrogen, oxygen, hydrogen, and helium. The pressure of such gases changes significantly with temperature. The superconducting heat transfer tube 202a-2 is an existing object with a relatively fast heat transfer rate. It is an inorganic heat transfer element successfully researched and developed by Professor Qu Yuzhi in the 1980s. It is convenient to sense the temperature in the thawing chamber 101 in real time, which is convenient for subsequent work.

[0036] Operation process: First, the coal car cargo frame 104 carrying frozen coal is placed in the thawing chamber 101. Then, steam is introduced into the steam input pipe 102b of the pipeline assembly 102, so that steam fills the main steam delivery pipe 102a and the branch steam delivery pipe 102c, thereby heating the thawing chamber 101 and thawing the frozen coal. When the superconducting heat transfer pipe 202a-2 in the temperature control assembly 202 transfers heat to the gas-sensing piston 202a-1, the gas-sensing piston 202a-1 drives the flow-closing element 202c to block the connection between the main steam delivery pipe 102a and the branch steam delivery pipe 102c, stopping the excessive input of steam. At the same time, it will drive the trigger element 202b to start the operation of the subsequent mechanism.

[0037] Example 2

[0038] Reference Figures 1-6 This embodiment differs from the first embodiment in that: the trigger 202b includes a start button 202b-1 disposed in the temperature control box 201, and a trigger block 202b-2 disposed on the first piston rod 202a-3; the end of the trigger block 202b-2 near the start button 202b-1 is provided with a smooth curved surface. The purpose of providing a smooth curved surface at the end of the trigger block 202b-2 near the start button 202b-1 is to prevent the trigger block 202b-2 from pressing the start button 202b-1 more smoothly, and to avoid getting stuck at this position, which would prevent subsequent work from being carried out.

[0039] Specifically, the closed-loop component 202c includes a slide rail block 202c-1 disposed within the temperature control box 201, a pulley rod 202c-2 disposed on the slide rail block 202c-1, a limiting plate 202c-3 disposed on the pulley rod 202c-2, and multiple closed-loop plugs 202c-4 disposed on the pulley rod 202c-2; the slide rail block 202c-1 is connected to the second piston rod 202a-4, and the diameter of the limiting plate 202c-3 is the same as that of the main steam conveying pipe 10. The inner diameters of the 2a pipes are matched, and the diameter of the limiting plate 202c-3 is matched with the inner diameter of the main steam conveying pipe 102a so that the main steam conveying pipe 102a can limit the pulley rod 202c-2 and prevent it from tipping over. The multiple flow-closing plugs 202c-4 are matched with the distribution steam conveying pipe 102c so that when the flow-closing plug 202c-4 rises, it can block the connection between the distribution steam conveying pipe 102c and the main steam conveying pipe 102a.

[0040] The rest of the structure is the same as in Example 1.

[0041] Operation process: The pneumatic piston 202a-1 drives the trigger 202b and the flow-closing element 202c, causing the trigger block 202b-2 to move towards the start button 202b-1. The start button 202b-1 is kept in a pressed-on state until the temperature drops and the trigger block 202b-2 resets under the action of the pneumatic piston 202a-1, at which point the start button 202b-1 is no longer pressed. During the above process, the slide block 202c-1 moves under the action of the pneumatic piston 202a-1. At this time, the pulley rod 202c-2 gradually rises, causing the flow-closing plug 202c-4 to block the connection between the main steam delivery pipe 102a and the branch steam delivery pipe 102c, thereby stopping the continued delivery of steam.

[0042] Example 3

[0043] Reference Figures 1-8 A steam-type thawing chamber for frozen coal also includes a power mechanism 300, comprising a housing frame 301 disposed on the thawing chamber 101, a motor 302 disposed within the housing frame 301, and a drive assembly 303; a vibration mechanism 400, comprising a striking port 401 disposed on the thawing chamber 101, a meshing box 402 disposed on the thawing chamber 101, and a meshing assembly 403 disposed within the meshing box 402; and a start button 202b-1 electrically connected to the motor 302, wherein the purpose of electrically connecting the start button 202b-1 to the motor 302 is to enable the temperature control mechanism 200 to automatically control the start and stop of the motor 302.

[0044] Specifically, the drive assembly 303 includes a support frame 303a, an upper drive shaft 303b disposed on the support frame 303a, a lower drive shaft 303c disposed on the support frame 303a, and a transmission belt 303d disposed on the upper drive shaft 303b and the lower drive shaft 303c; a first drive gear 303b-1 is disposed on the upper drive shaft 303b, a second drive gear 303c-1 is disposed on the lower drive shaft 303c, and the transmission belt 303d is adapted to the first drive gear 303b-1 and the second drive gear 303c-1; the upper drive shaft 303b passes through the support frame 303a and extends into the engagement box 402.

[0045] Furthermore, the meshing assembly 403 includes a sliding plate 403a disposed within the meshing box 402, a half gear 403b disposed on the upper drive shaft 303b located within the meshing box 402, and a striking element 403c disposed within the meshing box 402. The purpose of the half gear 403b is to enable the striking element 403c to obtain sufficient impact force so as to achieve a significant knocking effect. The sliding plate 403a is provided with serrations 403a-1, and the half gear 403b can mesh with the serrations 403a-1.

[0046] Furthermore, the striking component 403c includes a telescopic rod 403c-1 disposed within the engagement box 402, a buffer spring 403c-2 sleeved on the telescopic rod 403c-1, a vibrating pestle 403c-3 disposed on the telescopic rod 403c-1, and a connecting rod 403c-4 disposed between the vibrating pestle 403c-3 and the sliding plate 403a. The purpose of the buffer spring 403c-2 is to provide an instantaneous elastic force when the sawtooth edge of the half gear 403b rotates, causing the vibrating pestle 403c-3 to be ejected and vibrated through the striking port 401 to strike and vibrate the coal car cargo frame 104 inside, thereby causing the frozen coal adhering to the train car body to scatter, expanding its heat delivery area and improving the thawing efficiency.

[0047] The rest of the structure is the same as in Example 2.

[0048] Operation process: During the above process, when the trigger 202b presses the start button 202b-1, the motor 302 will start, which will drive the half gear 403b to rotate through the drive component 303, causing the sliding plate 403a to move into the meshing box 402. At this time, the buffer spring 403c-2 is in a compressed state. When the half gear 403b rotates half a turn, the buffer spring 403c-2 will give the vibrating pestle 403c-3 an instantaneous elastic force. Under the action of this process, the vibrating pestle 403c-3 will strike the coal car cargo frame 104 in the thawing chamber 101, and repeat this vibrating process until the thawing work in the thawing chamber 101 is completed and the temperature drops to the predetermined value. At this time, the gas piston 202a-1 will drive the trigger block 202b-2 to reset. At this time, the start button 202b-1 will no longer be pressed, the motor 302 will be turned off, and the vibrating mechanism 400 will stop running. At this time, the thawing work of frozen coal is completed.
