Description

Technical Field

[0001] The present invention relates to the technical field of coal gasification fine slag dehydration and drying, and specifically relates to a device for transporting and storing coal gasification fine slag in place. Background Art

[0002] Coal gasification fine slag is the fine slag generated during the coal gasification production process, which is fine coal particles and fine ash that are incompletely converted after high-temperature combustion and reaction in the gasifier. Its fine coal particles are somewhat similar to semi-coke. Before storage, coal gasification fine slag needs to be dehydrated. During the dehydration process, a transport vehicle is used to transfer the coal gasification fine slag. During the transfer process, it is necessary to load the coal gasification fine slag onto the vehicle, which increases the transfer cost. Moreover, when transported by a transport vehicle, the coal gasification fine slag is prone to leakage, which is likely to cause environmental pollution.

[0003] For example, a fly ash storage bin drying device with the publication number CN210773207U, by setting an activated carbon drying layer, in cooperation with the meshing connection of the driving gear and the driven gear, the traction of the fan on the air, and the heating of the traction air by the electric heating tube, is convenient for drying the fly ash in the bin body. It not only avoids the phenomenon of fly ash being damp and sticky, but also ensures the normal feeding of fly ash. Another example is a fly ash drying device with the publication number CN212320352U. Through the sliding connection of the bidirectional chute and the positioning block, the rotating rotating rod can drive the connecting plate to vibrate back and forth. Then, through the baffle and the supporting spring, the knocking hammer knocks on the shell, causing the inner wall of the shell to vibrate, and thus shaking off the fly ash on the inner wall. However, when the material enters the bin after feeding in actual use, there will be a certain degree of caking in the material. During the subsequent drying work, due to the existence of the caking, the moisture inside the caking is difficult to volatilize, which will increase the drying time and reduce the drying efficiency, and there are certain defects in use.

[0004] Therefore, we propose a device for transporting and storing coal gasification fine slag in place to solve the problems raised above. Summary of the Invention

[0025] By adopting the above technical solution, it is avoided that the pulverized coal gasification fine slag leaks out through the sliding groove.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: for the device for in-situ transportation and storage of pulverized coal gasification fine slag, a rotating assembly is arranged inside and outside the storage bin, so that when drying the pulverized coal gasification fine slag, transportation is not required, which can save costs and avoid environmental pollution. When drying the pulverized coal gasification fine slag, the generated lumps can be dispersed to avoid affecting the drying efficiency of the pulverized coal gasification fine slag, and the practicability is improved;

[0027] 1. A rotating component is provided inside and outside the storage bin. When drying the fine slag of coal gasification, the fine slag of coal gasification is poured into the feeding hopper, and the driving motor is started to drive the spiral blade to rotate, so that the spiral blade can push the fine slag of coal gasification, and then the fine slag of coal gasification can be sent into the storage bin through the feeding pipe. While the spiral blade rotates, it can drive the rotating shaft to rotate. After the rotating shaft rotates, it drives the rotating shaft to rotate through the cooperation of the first belt pulley and the second belt pulley. After the rotating shaft rotates, it drives the rotating shaft on one side to rotate through the cooperation of the second belt pulley and the fourth belt pulley. Through the cooperation of the fourth belt pulley and the third belt pulley, the two rotating shafts rotate synchronously. Then, the fine slag of coal gasification entering the storage bin can fall between the two rotating shafts under the action of the guide plate. By blowing air with a blower, after the two rotating shafts rotate, the fixed rods rotate alternately, so that the lumps contained in the fine slag of coal gasification can be broken up, which can improve the drying efficiency of the fine slag of coal gasification. The dried fine slag of coal gasification falls on the top of the partition plate. A valve is provided on the feeding pipe of the partition plate. When the dried fine slag of coal gasification is completely dry, the valve is opened, and the dried fine slag of coal gasification can fall into the lower part of the storage bin for storage. And during the drying process, a dust collector can be connected through the installation pipe, so that dust can be avoided during the drying of the fine slag of coal gasification, and the fine slag of coal gasification can be transported and stored on-site. Through the rotating component, the fine slag of coal gasification does not need to be transferred during drying, which can save costs and avoid environmental pollution. And when drying the fine slag of coal gasification, the generated lumps can be broken up to avoid affecting the drying efficiency of the fine slag of coal gasification, thus improving the practicability;

[0028] 2. During the rotation of the rotating rod, it can drive the turntable to rotate offset. While the turntable rotates, the ball on the movable rod rotates in the annular groove. After the turntable rotates, it can lift the movable rod. After the movable rod is lifted, the fine slag of coal gasification can fall above the cross block. The cross block can cut the fine slag of coal gasification to avoid the lumps of the fine slag of coal gasification being too large, which is beneficial to the subsequent drying of the fine slag of coal gasification and improves the drying efficiency. During the reciprocating movement of the movable rod, it can drive the two movable plates to move up and down continuously. The movable plate can drive the roller to rotate on the mounting rack, so that the movable plate can rotate while moving. Through the up and down reciprocating movement of the movable plate, the angle between the two movable plates can be continuously changed. The fine slag of coal gasification can fall along the guide of the movable plate, and the continuously changing angle of the movable plate can change the feeding position of the fine slag of coal gasification, thereby expanding the feeding range of the fine slag of coal gasification and avoiding excessive concentration of feeding, so as not to affect the drying efficiency;

[0029] 3. When feeding, there is a certain amount of moisture in the fine slag of coal gasification, and its viscosity is relatively high. After the fine slag of coal gasification is poured into the feeding hopper, the driving motor runs to drive the disc to rotate. The disc can rotate eccentrically. Through the cooperation of the arc-shaped block and the annular chute, the moving rod can be driven to move up and down reciprocally. The moving rod can slide in the sliding groove, and then drive the cross member to move up and down reciprocally. When the cross member moves upward, its top is relatively sharp, and the fine slag of coal gasification will not cause too much resistance to the movement of the cross member. When the cross member moves downward, its bottom is relatively flat, so that the downward movement of the cross member can provide a thrust to the fine slag of coal gasification, avoiding the excessive viscosity of the fine slag of coal gasification from adhering to the inside of the feeding hopper, avoiding the feeding speed from being too slow, and avoiding affecting the normal transportation of the fine slag of coal gasification.

[0049] Embodiment 1

[0050] As Figures 1-5As shown in the figure, a rotating component 2 is arranged inside and outside the storage bin 1. When drying the fine slag of coal gasification, the fine slag of coal gasification is poured into the feeding hopper 103, and the driving motor 104 is started to drive the spiral blade 106 to rotate, so that the spiral blade 106 can push the fine slag of coal gasification, and then the fine slag of coal gasification can be sent into the storage bin 1 through the feeding pipe 101. While the spiral blade 106 rotates, it can drive the rotating shaft 201 to rotate. After the rotating shaft 201 rotates, it drives the rotating shaft 207 to rotate through the cooperation of the first belt pulley 203 and the second belt pulley 206. After the rotating shaft 207 rotates, it drives the rotating shaft 207 on one side to rotate through the cooperation of the second belt pulley 206 and the fourth belt pulley 209. Through the cooperation of the fourth belt pulley 209 and the third belt pulley 208, the two rotating shafts 207 rotate synchronously. Then, the fine slag of coal gasification entering the storage bin 1 can fall between the two rotating shafts 207 under the action of the guide plate 205.

And during the drying process, a dust collector can be connected through the installation pipe 108, so that dust can be avoided when drying the fine slag of coal gasification, so that the fine slag of coal gasification can be transported and stored locally. Through the rotating component 2, it is not necessary to transfer the fine slag of coal gasification during drying, which can save costs and avoid environmental pollution.

[0053] Embodiment 2

[0054] As Figure 3 AndFigures 6-7 As shown, during the rotation of the rotating rod 204, it can drive the turntable 211 to perform offset rotation. While the turntable 211 rotates, the ball 2141 on the movable rod 214 rotates in the annular groove 212. After the turntable 211 rotates, it can lift the movable rod 214.

[0058] Embodiment 3

[0059] As Figure 3 and Figures 8-9As shown, when feeding, there is a certain amount of moisture in the fine slag of coal gasification, and the viscosity is relatively high. After the fine slag of coal gasification is poured into the feeding hopper 103, the driving motor 104 runs to drive the disc 301 to rotate. The disc 301 can rotate offset. Through the cooperation of the arc-shaped block 303 and the annular chute 302, the moving rod 304 can be driven to move up and down reciprocally. The moving rod 304 can slide in the sliding groove 306, and then drive the cross member 308 to move up and down reciprocally. When the cross member 308 moves upward, the top is relatively sharp, and the fine slag of coal gasification will not cause too much resistance to the movement of the cross member 308. When the cross member 308 moves downward, the bottom is relatively flat, so that the downward movement of the cross member 308 can provide a thrust to the fine slag of coal gasification, avoiding the excessive viscosity of the fine slag of coal gasification from adhering to the inside of the feeding hopper 103, avoiding the feeding speed from being too slow, and avoiding affecting the normal transportation of the fine slag of coal gasification.

[0060] Working principle: When using the device for in-situ transportation and storage of fine slag of coal gasification, first, according to Figures 1-9 As shown, when drying the fine slag of coal gasification, pour the fine slag of coal gasification into the feeding hopper 103, start the driving motor 104 to drive the spiral blade 106 to rotate, so that the spiral blade 106 can push the fine slag of coal gasification, and then the fine slag of coal gasification can be sent into the storage bin 1 through the feeding pipe 101. While the spiral blade 106 rotates, it can drive the rotating shaft 201 to rotate. After the rotating shaft 201 rotates, it drives the rotating shaft 207 to rotate through the cooperation of the first belt pulley 203 and the second belt pulley 206. After the rotating shaft 207 rotates, it drives the rotating shaft 207 on one side to rotate through the cooperation of the second belt pulley 206 and the fourth belt pulley 209. Through the cooperation of the fourth belt pulley 209 and the third belt pulley 208, the two rotating shafts 207 rotate synchronously. Then, the fine slag of coal gasification entering the storage bin 1 can fall between the two rotating shafts 207 under the action of the guide plate 205. Blow air through the fan 110. After the two rotating shafts 207 rotate, the fixed rods 210 rotate alternately, so that the lumps contained in the fine slag of coal gasification can be broken up, which can improve the drying efficiency of the fine slag of coal gasification. The dried fine slag of coal gasification falls on the top of the partition plate 107. A valve is arranged on the discharge pipe of the partition plate 107. When the dried fine slag of coal gasification is completely dry, the valve is opened, and the dried fine slag of coal gasification can fall into the lower part of the storage bin 1 for storage. And during the drying process, the dust collector can be connected through the installation pipe 108, so that dust is avoided during the drying of the fine slag of coal gasification, and the in-situ transportation and storage of the fine slag of coal gasification can be carried out;

[0061] During the rotation process, the rotating rod 204 can drive the turntable 211 to perform an offset rotation. While the turntable 211 is rotating, the ball 2141 on the movable rod 214 rotates in the annular groove 212. After the turntable 211 rotates, it can lift the movable rod 214. After the movable rod 214 is lifted, the gasification fine slag can fall above the cross block 215. The cross block 215 can cut the gasification fine slag to prevent the gasification fine slag from agglomerating too large, which is beneficial to the subsequent drying of the gasification fine slag and improves the drying efficiency. During the reciprocating movement of the movable rod 214, it can drive the two movable plates 216 to continuously move up and down. The movable plates 216 can drive the rollers 218 to rotate on the mounting frame 217, so that the movable plates 216 can rotate while moving. Through the reciprocating up and down movement of the movable plates 216, the angle between the two movable plates 216 can be continuously changed. The gasification fine slag can fall along the guidance of the movable plates 216, and the continuously changing angle of the movable plates 216 can change the discharging position of the gasification fine slag, thereby expanding the discharging range of the gasification fine slag. When feeding, there is a certain amount of moisture in the gasification fine slag and it has a large viscosity. After the gasification fine slag is poured into the feeding hopper 103, the driving motor 104 runs to drive the disc 301 to rotate. The disc 301 can perform an offset rotation. Through the cooperation of the arc block 303 and the annular chute 302, it can drive the moving rod 304 to reciprocate up and down. The moving rod 304 can slide in the sliding groove 306, and then drive the cross member 308 to reciprocate up and down. The top of the cross member 308 is relatively sharp during the upward movement, and the gasification fine slag will not cause too much resistance to the movement of the cross member 308. The bottom of the cross member 308 is relatively flat during the downward movement, so that the downward movement of the cross member 308 can provide a thrust to the gasification fine slag, preventing the gasification fine slag from adhering to the inside of the feeding hopper 103 due to its large viscosity and avoiding slow feeding speed.
