Description

Technical Field

[0001] This invention belongs to the field of heat-absorbing particle transportation technology, and specifically relates to a particle transportation device. Background Technology

[0002] Solid particles, with their high temperature and low cost, are considered one of the most promising heat storage media for third-generation concentrated solar power (CSP). One of the challenges of particle heat storage technology is the large-capacity, high-temperature particle lifting system. Material lifting systems mainly consist of bucket elevators, screw conveyors, pneumatic conveyors, and mine hoists. For lifting and transporting high-temperature materials, the mechanical moving parts of bucket elevators and screw conveyors are in high-temperature environments, requiring the use of large amounts of high-performance alloy materials, and they also suffer from material return issues, resulting in low lifting efficiency. Pneumatic conveyors use high-pressure gas to transport particles, resulting in significant heat loss, considerable pipeline wear, and limited conveying height. Mine hoists are commonly used for deep-well lifting in underground mining, lifting weights up to 60 tons and heights up to 2000 meters. However, mine hoists primarily lift room-temperature minerals, and lifting high-temperature materials presents problems such as significant heat loss during the lifting process (especially during loading and unloading) and low lifting efficiency.

[0073] like Figure 1 The illustration shows a pellet conveying device according to this application, comprising a pellet lifting mechanism 10 and transverse pellet conveying mechanisms 20 located at the upper and lower ends of the pellet lifting mechanism 10. The transverse pellet conveying mechanism 20 located at the lower end is below the lower storage tank 50. Particles in the lower storage tank 50 are first transferred to a pellet tank 24. The pellet tank 24 is then transported to the lower end of the pellet lifting mechanism 10 via the transverse pellet conveying mechanism 20. After being lifted to the top by the pellet lifting mechanism 10, the pellet tank 24 is transported to the upper storage tank 40 via the transverse pellet conveying mechanism 20 located at the upper end, where the particles are then transferred to the upper storage tank 40.

[0074] Specifically, such as Figure 2 As shown in Figures 4 and 5, the transverse particle transport mechanism 20 includes: a moving guide rail 21, a transport vehicle 22, a transverse drive assembly 23, a particle tank 24, and an opening and closing assembly 25.

[0075] One end of the moving guide rail 21 is connected to the pellet lifting mechanism 10, and the other end is disposed away from the pellet lifting mechanism 10. The transport vehicle 22 can move along the moving guide rail 21, thereby moving away from or close to the pellet lifting mechanism 10. The lateral drive assembly 23 is operably connected to the transport vehicle 22 to drive the transport vehicle 22 to move along the moving guide rail 21. The pellet tank 24 is connected to the transport vehicle 22. The upper end of the pellet tank 24 is provided with a feed inlet 241 and a feed locking mechanism 242 that can operably open or close the feed inlet 241. The lower end of the pellet tank 24 is provided with a discharge outlet 243 and a discharge locking mechanism 244 that can operably open or close the discharge outlet 243. The opening and closing assembly 25 is operably connected to the feed locking mechanism 242 or the discharge locking mechanism 244 to open or close the feed locking mechanism 242 or the discharge locking mechanism 244.

[0076] like Figure 2 and 4 As shown in the embodiments of this application, the upper and lower ends of the pellet tank 24 are respectively provided with a feed inlet 241 and a discharge outlet 243. Therefore, when transferring pellets to or from the pellet tank 24, it is not necessary to turn the pellet tank 24, thereby reducing the loss of pellet temperature and avoiding safety hazards.

[0077] In embodiments of this application, the lateral drive assembly 23 includes: a lateral guide rail 231, a lateral drive rail 232, and a lateral drive motor 233.

[0078] The transverse guide rail 231 is arranged along the direction of the moving guide rail 21. The transverse drive rail 232 is slidably connected to the transverse guide rail 231. The transverse drive motor 233 drives the transverse drive rail 232 to move along the transverse guide rail 231.

[0079] Specifically, a drive rack 2321 is provided on the transverse drive rail 232, and a transverse drive motor 233 is connected to the transverse guide rail 231. The motor shaft of the transverse drive motor 233 is provided with drive teeth 2331 that mesh with the drive rack 2321.

[0080] Preferably, such as Figure 2 and 8 As shown, the lateral drive assembly 23 also includes a locking pin 234 and a locking cylinder 235.

[0081] Locking pin 234 engages with locking hole 221 provided on transport vehicle 22 to lock transport vehicle 22. Locking cylinder 235 is connected to locking pin 234 and drives locking pin 234 into or away from locking hole 221. Locking cylinder 235 is connected to transverse drive rail 232. By means of locking pin 234 and locking cylinder 235, transport vehicle 22 can be selectively locked to or released from transverse drive rail 232 in the transverse direction.

[0082] In embodiments of this application, the lateral drive assembly 23 further includes a weighing assembly 27. The weighing assembly 27 is used to weigh the particles in the particle tank 24 on the transport vehicle 22. Specifically, the weighing assembly 27 is disposed below the lateral drive rail 232. When the transport vehicle 22 moves to the loading position, the weighing assembly 27 is located below the transport vehicle 22. At this time, the weighing assembly 27 can detect the weight change of the object above the lateral drive rail 232, and thus detect the weight of the particles transferred to the particle tank 24. It is understood that during the loading process, when the transport vehicle 22 is weighed by the weighing assembly 27, the locking cylinder 235 controls the locking pin 234 to be pulled out to prevent interference with the weighing.

[0083] like Figure 2 As shown, the feed locking mechanism 242 includes a feed sealing pin 2421 slidably connected to the pellet tank 24, the discharge locking mechanism 244 includes a discharge sealing pin 2441 slidably connected to the pellet tank 24, and the opening and closing assembly 25 is operably connected to the feed sealing pin 2421 and drives the feed sealing pin 2421 to open or close the feed port 241, or is operably connected to the discharge sealing pin 2441 and drives the discharge sealing pin 2441 to open or close the discharge port 243.

[0084] Among them, such as Figure 4 and 5 As shown, the opening and closing assembly 25 includes: a clamping structure 251, a guide rail 252, a first cylinder 253, and a mounting base 254.

[0085] The clamping structure 251 operably clamps the feed sealing pin 2421 or the discharge sealing pin 2441. A guide rail 252 guides the clamping structure 251. A first cylinder 253 is connected to the clamping structure 251 to drive it closer to or further away from the pellet container 24. A mounting base 254 is used to mount the first cylinder 253 and the guide rail 252.

[0086] Specifically, the clamping structure 251 includes: a support base plate 255, a second cylinder 256, two clamping arms 257, a limiting member 258, and a guide groove 259.

[0087] The support base plate 255 is slidably connected to the guide rail 252. A second cylinder 256 is connected to a limiting member 258. Two clamping arms 257 are connected to the second cylinder 256, which drives the clamping arms 257 to clamp or open, thereby clamping or releasing the sealing pin. The limiting member 258 is disposed on the support base plate 255 and located between the two clamping arms 257, thereby limiting the maximum clamping width of the clamping arms 257. A guide groove 259 is disposed on the support base plate 255, and the clamping arms 257 have guide portions 260 that cooperate with the guide groove 259.

[0088] In embodiments of this application, the lateral particle transport mechanism 20 further includes a first limiting component 26. The first limiting component 26 is operable to lock or unlock the transport vehicle 22, holding the transport vehicle 22 in a predetermined position.

[0089] Specifically, the transport vehicle 22 is equipped with a positioning structure 28 that cooperates with the first limiting component 26. When the transport vehicle moves to the loading or unloading position, the first limiting component 26 cooperates with the positioning structure 28 on the transport vehicle 22 to keep the transport vehicle 22 in a predetermined position. Figure 10 As shown in the embodiment of this application, the positioning structure 28 is a positioning recess provided on both sides of the transport vehicle 22, and the first limiting component 26 includes positioning protrusions located on both sides of the transport vehicle 22 that cooperate with the positioning recesses. Preferably, the positioning protrusions can freely extend and retract under the cooperation of springs, so that they elastically extend and retract to move into or out of the corresponding positioning recess during the movement of the transport vehicle 22. The first limiting component 26 and the positioning structure 28 on the transport vehicle 22 together form part of the positioning device.

[0090] like Figure 3 and 9 As shown in the embodiments of this application, the pellet conveying device further includes an alignment and fastening assembly 30. The alignment and fastening assembly 30 is disposed at the feed end of the upper storage tank 40 and / or the discharge end of the lower storage tank 50. The alignment and fastening assembly 30 is used to make the pellet tank 24 more tightly connected to the feed end of the upper storage tank 40 or the discharge end of the lower storage tank 50. Specifically, the alignment and fastening assembly 30 includes: a fixed sleeve 31, a sliding sleeve 33, a plurality of sliding guide pins 36, and a plurality of return springs 37.

[0091] The fixed sleeve 31 is connected to the outlet of the lower storage tank 50 or the inlet of the upper storage tank 40. A first annular mounting portion 32 is provided on the side of the fixed sleeve 31. A sliding sleeve 33 is fitted onto the fixed sleeve 31, and a second annular mounting portion 34 is provided on the side of the sliding sleeve 33. A guide plate 35 is provided at the end of the sliding sleeve 33 away from the fixed sleeve 31, and an inclined guide portion 351 is formed on one side of the guide plate 35. A plurality of sliding guide pins 36 are slidably inserted through the first annular mounting portion 32 and the second annular mounting portion 34 at intervals. A plurality of return springs 37 are respectively fitted onto the sliding guide pins 36 and located between the first annular mounting portion 32 and the second annular mounting portion 34. The inclined guide portion 351 is inclined towards the fixed sleeve 31 to guide the feed inlet 241 or discharge outlet 243 of the pellet tank 24. During the alignment process between the pellet tank 24 and the alignment fastening assembly 30, the feed inlet 241 or discharge outlet 243 of the pellet tank 24, guided by the inclined guide 351, overcomes the elastic force of the return spring 37 and compresses the sliding sleeve 33 towards the fixed sleeve 31. Thus, after the pellet tank 24 is properly aligned, it maintains a tight fit with the lower storage tank 50 or the upper storage tank 40.

[0092] like Figure 3 As shown in 4, 6 and 7, in the embodiments of this application, the particle lifting mechanism 10 includes: a lifting support assembly 11, a lifting frame 12 and a lifting assembly 13.

[0093] The lifting frame 12 is provided with a plurality of parallel sliding guide rails 121 extending in the vertical direction. The lifting assembly 13 is connected to the lifting support assembly 11 to drive the lifting support assembly 11 to move up and down.

[0094] Specifically, the lifting support assembly 11 includes: a support frame 111, a docking guide rail 112, a number of guide rollers 113, and a number of track-fitting structures 114.

[0095] A docking guide rail 112 is positioned below the support frame 111 and docks with the moving guide rail 21. Several guide rollers 113 are connected to the support frame 111, and the guide rollers 113 cooperate with corresponding sliding guide rails 121. Several track-fitting structures 114 are connected to the support frame 111, and the track-fitting structures 114 are positioned between the guide rollers 113 and the support frame 111.

[0096] Specifically, in the embodiments of this application, the lifting frame 12 is provided with four sliding guide rails 121, and the lifting support assembly 11 includes eight guide rollers 113 that respectively cooperate with the sliding guide rails 121. Four of the eight guide rollers 113 are located at the upper end of the support frame 111 and the other four are located at the lower end of the support frame 111.

[0097] In the embodiments of this application, the track-fitting structure 114 is a flexible plate 114. Specifically, the flexible plate 114 is made of foamed silicone. This allows for a flexible fit between the support frame 111 and the sliding guide rail 121, resulting in a tighter fit between the lifting support assembly 11 and the lifting frame 12, reducing wear on the sliding guide rail 121 and the guide rollers 113. Simultaneously, the deformable flexible plate 114 also mitigates the swaying problem that occurs during the vertical movement of the lifting support assembly 11.

[0098] like Figure 6 As shown in the embodiments of this application, the lifting support assembly 11 further includes several mounting and mating structures 115 for mounting guide rollers 113 and track-fitting structures 114.

The fixing plate 117 is connected to the support frame 111, and the guide rollers 113 are connected to the fixing plate 117. Thus, the flexible plate 114 can undergo a certain deformation, and since both the mounting groove 116 and the fixing plate 117 are made of metal, the fixing plate 117 can move relative to the mounting groove 116 when the flexible plate 114 deforms. In this application, the mounting groove 116 is formed by several short plates 119 arranged at intervals.

[0099] In embodiments of this application, the lifting support assembly 11 further includes a second limiting assembly 118. The second limiting assembly 118 is disposed on the support frame 111 and can operably lock or unlock the transport vehicle 22, holding the transport vehicle 22 in a predetermined position.

[0100] In the embodiments of this application, the second limiting component 118 is structurally identical to the aforementioned first limiting component 26. The second limiting component 118 includes positioning protrusions located on both sides of the transport vehicle 22 that engage with positioning recesses. Preferably, the positioning protrusions are freely extendable and retractable with the assistance of springs, thereby elastically extending and retracting into or out of the corresponding positioning recesses during the movement of the transport vehicle 22. The second limiting component 118 and the positioning structure 28 on the transport vehicle 22 together form another part of the positioning device.

[0101] Preferably, the lateral particle transport mechanism 20 further includes a first position detection element. The first position detection element is a position sensor used to detect whether the lateral particle transport mechanism 20 transports the transport vehicle 22 onto the lifting support assembly 11.

[0102] Preferably, the particle lifting mechanism 10 further includes a second position detection element and a third position detection element. The second and third position detection elements are position sensors. The second position detection element is disposed below the lifting frame 12 to detect whether the lifting support assembly 11 has reached a designated lower position. The third position detection element is disposed above the lifting frame 12 to detect whether the lifting support assembly 11 has reached a designated upper position.

[0103] like Figure 3 and 7 As shown in the embodiments of this application, the lifting assembly 13 includes a lifting machine 131 and a pulley assembly 132. The lifting machine 131 is disposed on the ground. The pulley assembly 132 is disposed on the top of the lifting frame 12, and the traction rope of the lifting machine 131 passes around the pulley assembly 132, extends from the top of the lifting frame 12, and connects to the support frame 111.

[0104] It is understood that multiple transverse particle transport mechanisms 20 can be provided at the lower end of the particle lifting mechanism 10, and corresponding multiple transverse particle transport mechanisms 20 can be provided at the upper end of the particle lifting mechanism 10 to improve transport efficiency. The basic principles, main features, and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
