However, the current ring conveyor does not set a special cooling treatment device, and the materials to be cooled need to be naturally cooled during the conveying process, and after the transfer is completed, the materials to be cooled still need to be placed for air cooling, the cooling speed is slow, the time consumption is long, the occupied area is large, and the production efficiency is greatly affected. SUMMARY

[0003] The utility model wants to solve the problem to provide a ring conveying cooling device, and the ring conveying cooling device can quickly reduce the temperature of the materials to be cooled, is favorable for shortening the cooling time, and improves production efficiency.

[0004] In order to solve the above technical problem, the technical scheme adopted by the utility model is as follows:

[0005] A ring conveying cooling device, comprising a rotating disc and a rotating drive mechanism capable of driving the rotating disc to rotate, a plurality of hoppers are uniformly distributed along the circumferential direction of the rotating disc on the edge of the rotating disc, characterized by further comprising a spraying mechanism and a hopper turnover mechanism capable of driving the corresponding hopper to turn over outward, the rotating disc is sequentially provided with a feeding station, a spraying station and a discharging station along the rotating direction of the rotating disc, the spraying mechanism is arranged at the spraying station, and the spray head of the spraying mechanism faces each hopper on the spraying station, the outside of each hopper is hingedly installed on the rotating disc, and the hopper turnover mechanism is arranged at the discharging station.

[0006] In operation, the rotary disc is rotated by the driving mechanism to sequentially transport the hoppers on the feeding station to the spraying station, the discharging station, and then back to the feeding station, and so on. The rotary disc rotates one hopper position at a time in a step-by-step manner, and when the rotary disc is temporarily stopped, each station simultaneously performs the following operations: at the feeding station, the material to be cooled (e.g. industrial silicon blocks or ferroalloy blocks) is added to the hoppers on the feeding station; when the hoppers containing the material to be cooled are brought to the spraying station, the nozzles of the spraying mechanism are directed towards the hoppers on the spraying station, and the nozzles spray cooling water to rapidly cool the material to be cooled; the cooled material continues to rotate with the rotary disc to the discharging station, and the hopper overturning mechanism drives the hoppers to overturn outwardly to pour the material into the collecting device below the hoppers; after the pouring is completed, the hoppers are turned inwardly to return to the original position, ready for the next feeding.

[0007] Generally, during the entire operation, the center of gravity of the hoppers is located inside the hinge point of the rotary disc and outside the hoppers. At the discharging station, after the hoppers are overturned outwardly, the center of gravity of the hoppers is still located inside the hinge point of the rotary disc and outside the hoppers, so that after the pouring is completed, the hoppers can be automatically turned inwardly to return to the original position by gravity.

[0008] In a preferred embodiment, the spraying mechanism comprises a water storage container, a water pump, a plurality of water pipes and a plurality of nozzles. The water inlet end of the water pump is connected to the water storage container, and the water outlet end of the water pump is in communication with the corresponding nozzles through the water pipes. Each nozzle is located above the hoppers on the spraying station. When spraying is required, the water pump is turned on to send the water in the water storage container to the corresponding nozzles through the water pipes, and the nozzles spray the high-temperature material in the hoppers. In a more preferred embodiment, the nozzles are arranged at equal intervals along the rotation direction of the rotary disc. Generally, the water sprayed by the spraying mechanism can cover multiple hoppers, which can prolong the time for which the high-temperature material in each hopper is sprayed and cooled.

[0009] In a further preferred embodiment, the spraying mechanism further comprises a water collecting tray and a return pipe. The water collecting tray is arranged below the rotary disc and corresponds to the positions of the nozzles. The water collecting tray is connected to the water storage container through the return pipe. Some of the water sprayed on the spraying station will drip onto the water collecting tray on the outside of the hoppers, and then be returned to the water storage container through the return pipe for recycling.

[0010] In a further preferred solution, the spraying mechanism further comprises a water vapor recovery mechanism, which comprises a gas collecting hood, a first gas pipe, an air blower and a second gas pipe. The gas collecting hood is arranged above each of the spray heads, and the opening at the bottom of the gas collecting hood faces each hopper on the spraying station. The cavity of the gas collecting hood is connected to the air inlet of the air blower through the first gas pipe, and the air outlet of the air blower is communicated with the water storage container through the second gas pipe. After the water sprayed on the material to be cooled absorbs heat and evaporates, a large amount of water vapor is generated. By turning on the air blower, the generated water vapor can be collected through the gas collecting hood. The water vapor is transported to the water storage container through the first gas pipe, the air blower and the second gas pipe, and is recovered and reused after condensation.

The pulling motor is mounted on the support, and the winding wheel is rotatably mounted on the support. The power output shaft of the pulling motor is in transmission connection with the winding wheel. One end of the pulling rope is wound around the winding wheel, and the other end of the pulling rope is connected with the flange. The inner end of the flange corresponds to the clamping mechanism. The inner end of the hopper rod is provided with a clamping ring which is in buckling cooperation with the outer end of the flange. When the hopper is not pouring material, the inner end of the flange is clamped by the clamping mechanism, and the outer end of the flange is in disengagement with the clamping ring of the inner end of the hopper rod. When the hopper is ready to pour material, the clamping mechanism is first moved outwardly by the inner-outer translation mechanism, so that the outer end of the flange approaches the clamping ring of the inner end of the hopper rod. With the clamping mechanism continuing to move outwardly by the inner-outer translation mechanism, the outer end of the flange is buckled with the clamping ring of the inner end of the hopper rod to form self-locking. Then, the clamping mechanism releases the inner end of the flange, the winding wheel is driven to rotate by the pulling motor, the rope is wound, the flange is pulled upwardly to drive the hopper to overturn outwardly, and after the pouring of material is completed, the winding wheel is driven to rotate reversely by the pulling motor, the rope is unwound, the flange drives the hopper to slowly overturn inwardly to reset. After the hopper is reset, the clamping mechanism is moved outwardly by the inner-outer translation mechanism to clamp the inner end of the flange, and the clamping mechanism is driven to move inwardly by the inner-outer translation mechanism to disengage the outer end of the flange from the clamping ring of the inner end of the hopper rod, so that the empty hopper on the discharging station is transferred to the feeding station with the rotation of the turntable. In addition, a guide wheel for guiding the pulling rope can be arranged on the support.

[0012] The inner and outer translation mechanism can adopt an electric cylinder, and the clamping mechanism can adopt a parallel finger cylinder. The cylinder body of the parallel finger cylinder is installed on the power output end of the electric cylinder. The two clamping jaws of the parallel finger cylinder correspond to the inner end of the flange.

Under the action of the second compression spring, the limiting rod has a tendency to move towards the first through hole (move from the first opening of the guide through hole to the second opening of the guide through hole). The first compression spring on the hopper rod is arranged between the inner ring and the outer ring, so that in the normal state, the inner ring and the outer ring on the hopper rod are relatively far away. When the outer end of the flange is to be matched with the clamping ring on the inner end of the hopper rod, with the outer movement of the clamping mechanism and the flange clamped thereby by the in-out translation mechanism, the inner ring gradually extends into the first through hole, and the slope surface on the clamping block is in contact with the circumferential surface of the inner ring, so that the limiting rod drives the clamping block to be buckled between the inner ring and the outer ring under the elastic cooperation of the second compression spring, forming a self-locking.

When the hopper turnover mechanism needs to drive the hopper to turn over, the worm screw elevator drives the screw to rise, pushes the bottom of the hopper, and makes the hopper turn over outward. In order to reduce the impact force on the bottom of the hopper when the screw rises, a buffer can be installed on the upper end of the screw. The corresponding position on the above-mentioned turntable is provided with a through hole for the screw to pass through.

[0015] Another preferred solution, the hopper turnover mechanism includes a hydraulic cylinder, which is fixedly installed on a base, the piston rod of the hydraulic cylinder faces upward and corresponds to the position of the bottom of the hopper (the position corresponding to the bottom of the hopper and the piston rod of the hydraulic cylinder should be offset from the hinge between the outer side of the hopper and the turntable).

The roller lever type buffer blocking cylinder generally comprises a cylinder body, a piston rod, a support seat and a roller, the cylinder body is installed on the edge of the turntable, the piston rod faces upward, the support seat is installed on the upper end of the piston rod, and the roller is rotatably installed on the support seat; the roller corresponds to the outer end of the hopper on the discharging station. In the initial state, the roller lever type buffer blocking cylinder is in the extended state, and the roller is located at the highest position. When the hopper turns over outward, the roller contacts the outer end of the hopper, and under the pressure of the hopper, the support seat and the roller correspondingly descend. When the hopper is to be reset, the pressure of the hopper is removed, the piston rod of the roller lever type buffer blocking cylinder automatically extends upward, drives the support seat and the roller thereon to rise, pushes the outer end of the hopper upward, and assists the hopper to turn over inward and reset smoothly.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0034] Example 1, such as Figures 1-10 As shown, the annular conveying and cooling device in this embodiment includes a turntable 1 and a rotation drive mechanism (not shown in the figure) that can drive the turntable 1 to rotate. Multiple hoppers 11 are evenly distributed around the circumference of the turntable 1 on the edge of the turntable 1. It also includes a spraying mechanism 2 and a hopper flipping mechanism 3 that can drive the corresponding hoppers 11 to flip outward. The turntable 1 is provided with a feeding station 12, a spraying station 13, and a discharging station 14 in sequence along the rotation direction of the turntable 1. The spraying mechanism 2 is set at the spraying station 13, and the nozzles 21 of the spraying mechanism 2 face each hopper 11 on the spraying station 13. The outer side of each hopper 11 is hinged to the turntable 1, and the hopper flipping mechanism 3 is set at the discharging station 14.

[0035] During operation, the rotary drive mechanism drives the turntable 1 to rotate, which sequentially transports the hopper 11 on the feeding station 12 to the spraying station 13 and the discharge station 14, and then transports it back to the feeding station 12, and so on. Turntable 1 rotates one hopper 11 position at a time in a stepwise manner. When turntable 1 stops rotating, each station works simultaneously: at feeding station 12, the material to be cooled (e.g., industrial silicon block or ferroalloy block) is added to the hopper 11 on feeding station 12; when the hopper 11 containing the material to be cooled is brought to spray station 13, the nozzles 21 of spray mechanism 2 face each hopper 11 on spray station 13, and cooling water is sprayed out through the nozzles 21 to quickly cool the material to be cooled; after cooling, the material continues to rotate with turntable 1 to discharge station 14, and hopper tilting mechanism 3 drives hopper 11 to tilt outward, pouring the material into the collection device below hopper 11; after the material is poured out, hopper 11 tilts inward back to its original position, ready for the next feeding.

[0036] Generally, the center of gravity of the hopper 11 is always on the outside of the hopper 11 and on the inside of the hinge point of the rotary disc 1 during the whole working process. Among them, on the discharging station 14, the hopper 11 is still on the outside of the hopper 11 and on the inside of the hinge point of the rotary disc 1 after the hopper 11 is turned outwards, so that the hopper 11 can be automatically turned inwards to the original position by gravity after the discharging is completed.

[0037] The spraying mechanism 2 comprises a water storage container 22, a water pump 23, a plurality of water pipes 24 and a plurality of the spray heads 21. The water inlet end of the water pump 23 is connected with the water storage container 22, the water outlet end of the water pump 23 is communicated with the corresponding spray head 21 through each water pipe 24, and each spray head 21 is above each hopper 11 on the spraying station 13. When spraying is needed, the water pump 23 is opened, the water pump 23 sends the water in the water storage container 22 to the corresponding spray head 21 through each water pipe 24, and the spray head 21 sprays water to cool the high-temperature material in each hopper 11. In a more preferred embodiment, each spray head 21 is arranged at equal intervals along the rotation direction of the rotary disc 1. Generally, the water sprayed by the spraying mechanism 2 can cover a plurality of hoppers 11, so that the time for which the high-temperature material in each hopper 11 is cooled by water spraying can be prolonged.

[0038] The spraying mechanism 2 further comprises a water collecting tray 25 and a return pipe 26. The water collecting tray 25 is arranged below the rotary disc 1 and corresponds to the positions of the spray heads 21. The water collecting tray 25 is connected with the water storage container 22 through the return pipe 26. A part of the water sprayed on the spraying station 13 will be sprayed to the outside of the hopper 11 and will drop on the water collecting tray 25, and then will be returned to the water storage container 22 through the return pipe 26 for recycling.

[0039] The spraying mechanism 2 further comprises a water vapor recovery mechanism 27. The water vapor recovery mechanism 27 comprises a gas collecting hood 271, a first gas pipe 272, an air blower 273 and a second gas pipe 274. The gas collecting hood 271 is arranged above each spray head 21, the opening at the bottom of the gas collecting hood 271 faces each hopper 11 on the spraying station 13, the cavity of the gas collecting hood 271 is connected with the air inlet of the air blower 273 through the first gas pipe 272, and the air outlet of the air blower 273 is communicated with the water storage container 22 through the second gas pipe 274. The water sprayed on the material to be cooled will evaporate after absorbing heat, and a large amount of water vapor will be generated. The air blower 273 is opened, the generated water vapor is collected through the gas collecting hood 271, and the water vapor is transported to the water storage container 22 through the first gas pipe 272, the air blower 273 and the second gas pipe 274 for recycling, and is reused after condensation.

The clamping mechanism 33 is installed on a power output end of the inner-outer translation mechanism 32 and can be driven by the inner-outer translation mechanism 32 to move inwardly and outwardly. The pulling motor 34 and the winding wheel 35 are arranged above the hopper 11 of the discharging station 14. The pulling motor 34 is installed on the support 31. The winding wheel 35 is rotatably installed on the support 31. A power output shaft of the pulling motor 34 is in transmission connection with the winding wheel 35. One end of the pulling rope 36 is wound around the winding wheel 35. The other end of the pulling rope 36 is connected with the flange 37. The inner end of the flange 37 corresponds to the clamping mechanism 33. The inner end of the hopper rod 15 is provided with a clamping ring 16 which is buckled with the outer end of the flange 37. When the hopper 11 is not pouring, the inner end of the flange 37 is clamped by the clamping mechanism 33. The outer end of the flange 37 is in a disengaged state with the clamping ring 16 of the inner end of the hopper rod 15. When the hopper 11 is ready to pour, the clamping mechanism 33 is first driven by the inner-outer translation mechanism 32 to move outwardly, so that the outer end of the flange 37 approaches the clamping ring 16 of the inner end of the hopper rod 15. With the inner-outer translation mechanism 32 continuously driving the clamping mechanism 33 to move outwardly, the outer end of the flange 37 is buckled with the clamping ring 16 of the inner end of the hopper rod 15 to form self-locking. Then, the clamping mechanism 33 releases the inner end of the flange 37. The winding wheel 35 is driven by the pulling motor 34 to rotate, so as to wind the pulling rope. The flange 37 is pulled upwardly to drive the hopper 11 to overturn outwardly. After the pouring is completed, the winding wheel 35 is reversely rotated by the pulling motor 34 to release the pulling rope, so that the flange 37 drives the hopper 11 to slowly overturn inwardly to reset. After the hopper 11 is reset, the clamping mechanism 33 is driven by the inner-outer translation mechanism 32 to move outwardly, so as to clamp the inner end of the flange 37. The clamping mechanism 33 is driven by the inner-outer translation mechanism 32 to move inwardly, so as to disengage the outer end of the flange 37 from the clamping ring 16 of the inner end of the hopper rod 15. The empty hopper 11 on the discharging station 14 is transferred to the feeding station 12 with the rotary disc 1. In addition, a guide wheel 37 for guiding the pulling rope 36 can be arranged on the support 31.

[0041] The inner-outer translation mechanism 32 can adopt an electric cylinder. The clamping mechanism 33 can adopt a parallel finger cylinder. A cylinder body 41 of the parallel finger cylinder is installed on a power output end of the electric cylinder. Two clamping jaws of the parallel finger cylinder correspond to the inner end of the flange 37. The two clamping jaws of the parallel finger cylinder can clamp the inner end of the flange 37 after moving towards each other. The two clamping jaws of the parallel finger cylinder can release the inner end of the flange 37 after moving away from each other.

Under the action of the second compression spring 3722, the limiting rod 3721 has a tendency to move toward the first through hole 371 (move from the first opening of the guide through hole 373 to the second opening of the guide through hole 373). The first compression spring 163 on the hopper rod 15 is arranged between the inner ring 161 and the outer ring 162, so that the inner ring 161 and the outer ring 162 on the hopper rod 15 are relatively far away in the normal state.When the outer end of the flange 37 is to be buckled with the snap ring 16 at the inner end of the hopper rod 15, as the inner-outer translation mechanism 32 drives the clamping mechanism 33 and the clamped flange 37 to move outward, the inner ring 161 gradually extends into the first through hole 371, and the inclined surface on the clamping block 3725 is in contact with the circumferential surface of the inner ring 161, so that the clamping block 3725 is buckled between the inner ring 161 and the outer ring 162 under the elastic cooperation of the second compression spring 3722, forming self-locking. When the outer end of the flange 37 is to be buckled with the snap ring 16 at the inner end of the hopper rod 15, as the inner-outer translation mechanism 32 drives the clamping mechanism 33 and the clamped flange 37 to move outward, the inclined surface of the clamping block 3725 between the inner ring 161 and the outer ring 162 is in contact with the circumferential surface of the outer ring 162, and the clamping block 3725 is moved outward out of the inner ring 161 and the outer ring 162, and then the clamping mechanism 33 and the clamped flange 37 are driven by the inner-outer translation mechanism 32 to move inward, the clamping block 3725 pulls the outer ring 162 inward, and the outer ring 162 moves inward on the hopper rod 15, the first compression spring 163 is compressed in the first annular groove 164, and the inner end surface of the outer ring 162 abuts the outer end surface of the inner ring 161. As the flange 37 gradually moves inward, the clamping block 3725 moves inward along the circumferential surface of the outer ring 162 and the circumferential surface of the inner ring 161 in turn, and then the outer end of the flange 37 is buckled with the snap ring 16 at the inner end of the hopper rod 15.

[0043] The annular conveying and cooling device also comprises a hopper support jacking and returning mechanism 4 arranged outside the rotating disc 1 and corresponding to the outer end of the hopper 11 on the discharging station 14. When discharging, the hopper 11 is turned outward, and after turning, the hopper support jacking and returning mechanism 4 supports the outer end of the hopper 11 to limit the turning angle of the hopper 11, prevents the turning angle of the hopper 11 from being too large when discharging, and enables the hopper 11 to discharge smoothly.

[0044] The hopper support lifting and return mechanism 4 employs a roller lever type damper blocking cylinder. This roller lever type damper blocking cylinder typically includes a cylinder body 41, a piston rod 42, a support seat 43, and a roller 44. The cylinder body 41 is mounted on the edge of the turntable 1, the piston rod 42 faces upwards, the support seat 43 is mounted on the upper end of the piston rod 42, and the roller 44 is rotatably mounted on the support seat 43. The roller 44 corresponds to and engages with the outer end of the hopper 11 at the discharge station 14. In the initial state, the roller lever type damper blocking cylinder is in the extended state, and the roller 44 is at its highest position. When the hopper 11 flips outwards, the roller 44 contacts the outer end of the hopper 11, and under the pressure of the hopper 11, the support seat 43 and the roller 44 descend accordingly. When the hopper 11 is to return to its original position, the pressure of the hopper 11 is removed, and the piston rod 42 of the roller lever buffer cylinder automatically extends upward, driving the support base 43 and the roller 44 on it to rise, so that the roller 44 pushes the outer end of the hopper 11 upward, assisting the hopper 11 to flip inward and return to its original position smoothly.

[0045] Example 2, as Figures 11-12 In this embodiment, the hopper tilting mechanism 3 includes a hydraulic cylinder, which is fixedly mounted on a base. The piston rod of the hydraulic cylinder faces upward and corresponds to the bottom of the hopper 11 (the position of the bottom of the hopper 11 corresponding to the piston rod of the hydraulic cylinder should be offset from the hinge point between the outer side of the hopper 11 and the turntable 1). When the hopper tilting mechanism 3 needs to drive the hopper 11 to tilt, the piston rod of the hydraulic cylinder extends upward and pushes the bottom of the hopper 11, causing the hopper 11 to tilt outward. To reduce the impact force on the bottom of the hopper 11 when the piston rod rises, a buffer can be installed at the upper end of the piston rod of the hydraulic cylinder. The turntable 1 is provided with a through hole 17 at the position corresponding to the piston rod of the hydraulic cylinder, allowing the piston rod of the hydraulic cylinder to pass through.
