DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-4A boiler high-temperature bottom ash conveying device comprises a cabinet 1, a feed port 2 is arranged above the cabinet 1, a crushing bin 3 is arranged above the cabinet 1, a material box 4 is arranged below the crushing bin 3, a material discharge mechanism 5 is arranged inside the cabinet 1, a conveyor belt 6 is arranged below the cabinet 1, the material discharge mechanism 5 comprises a rotating plate 51, the rotating plate 51 is rotatably connected to the material discharge box 4, an upper partition plate 52 is fixedly connected to the inner wall of the material discharge box 4, a lower partition plate 53 is fixedly connected to the inner wall of the material discharge box 4, a sliding partition plate 54 is slidably connected to the inner wall of the material discharge box 4, and a gap position between the upper partition plate 52 and the lower partition plate 53 is formed. The sliding partition 54 is not in the same vertical position, and the sliding partition 54 is in a region change that is consistent with the gap position of the upper partition plate 52 and the gap position of the lower partition plate 53 during the movement. By setting the gap position of the upper partition plate 52 and the lower partition plate 53, it is ensured that when the sliding partition 54 slides between the upper partition plate 52 and the lower partition plate 53, a small amount of waste slag can be driven to fall, so as to achieve the effect of controlling the amount of waste falling. An air pressure chamber 55 is provided in the inner wall of the discharge box 4, and a pushing block 56 is slidably connected to the inner wall of the air pressure chamber 55, and a control block 56 is slidably connected to the inner wall of the air pressure chamber 55. 7. The push block 56 is elastically connected to the inner wall of the air pressure chamber 55 through a spring 58. The control block 57 is connected to the rotating plate 51 through a pull rope 59. The pull rope 59 is inelastic, and the position where the pull rope 59 is connected to the rotating plate 51 is at the end of the rotating plate 51 away from the rotating shaft that is rotatably connected to the unloading box 4. By setting the properties of the pull rope 59, it is ensured that the pull rope 59 will not expand or contract after being subjected to tension, thereby ensuring that the pull rope 59 can pull the control block 57 after being subjected to tension to achieve the expected effect. A fan 510 is fixedly connected to the inner wall of the unloading box 4, and a temperature control component 511 is arranged inside the rotating plate 51. A spring piece 512 is fixedly connected to the bottom of the rotating plate 51, and one end of the spring piece 512 away from the rotating plate 51 is arranged on the inner wall of the discharge box 4. After the waste falls, the pull rope 59 is driven by the rotating plate 51 to be stressed, so that the control block 57 is stressed and the push block 56 and the sliding partition 54 are driven to move by air pressure. After the rotating plate 51 is reset, the spring 58 drives the push block 56 to reset and the sliding partition 54 to reset, so that the waste falls and the next group of waste can be automatically discharged after the rotating plate 51 is reset, so as to control the amount of each material discharge and ensure that the waste falling each time will not be too much, thereby affecting the use effect.

[0021] When in use, after the waste is crushed by the crushing bin 3, it first falls into the inside of the material box 4 and is in the area above the upper partition plate 52 waiting to fall. When the waste above the rotating plate 51 is cooled by the fan 510, the rotating plate 51 is released from the limit between the material box 4 and the rotating plate 51 rotates, so that the waste above the rotating plate 51 falls onto the conveyor belt 6. Since the rotating plate 51 pulls the pull rope 59 during the rotation process, the pull rope 59 is straightened. Then, the control block 57 is pulled downward, so that the internal space of the air pressure chamber 55 becomes larger, so that the internal pressure of the air pressure chamber 55 becomes smaller, so that the push block 56 is affected by the pressure and moves toward the side close to the air pressure chamber 55, and drives the sliding partition 54 to move toward the side close to the push block 56, so that the gap position opened on the sliding partition 54 is at the same vertical position as the gap position of the upper partition plate 52, so that the waste residue above the sliding partition 54 passes through the gap opened on the upper partition plate 52. The waste residue at the gap position of the sliding partition 54 is just above the lower partition plate 53. When the waste residue above the rotating plate 51 has finished falling, the rotating plate 51 is automatically reset under the drive of the spring 512. When the rotating plate 51 is reset, the pull rope 59 is not subjected to the tension. At this time, the push block 56 is automatically reset under the action of the spring 58, so that the sliding partition 54 is automatically reset under the push of the push block 56. At this time, the sliding partition 54 moves to make The gap obtained is in the same vertical position as the gap of the lower partition plate 53, so that the waste in the gap of the sliding partition plate 54 falls through the gap of the lower partition plate 53. At this time, if the waste is hot, the rotating plate 51 is restricted by the temperature control component 511 and cannot rotate. At this time, the waste is above the rotating plate 51 and is cooled down faster by the blowing of the fan 510. When the waste is cooled, the temperature control component 511 releases the limit, and the waste drives the rotating plate 51 to rotate under the drive of gravity and falls onto the conveyor belt 6.

[0022] See also Figure 1-5On the basis of the first embodiment, the temperature control component 511 includes an air pressure tube 5111, which is arranged in the inner wall of the rotating plate 51, and the material of the air pressure tube 5111 is copper, and the interior of the air pressure tube 5111 is filled with heat-conducting gas. By setting the material of the air pressure tube 5111, it is ensured that the heat outside the air pressure tube 5111 can be easily transferred to the interior of the air pressure tube 5111, and by setting the gas properties inside the air pressure tube 5111, it is ensured that the gas inside the air pressure tube 5111 is easy to expand after being heated, so as to achieve the expected effect. The air pressure tube 5111 is slidably connected with a trapezoidal block 5112, and the trapezoidal block 5112 is elastically connected to the inner wall of the air pressure tube 5111 through a spring 2 5113. A clamping hole 5115 is opened on the inner wall of the blanking box 4, and an inclined The trapezoidal block 5112 has only the inclined surface inside the clamping hole 5115 at room temperature and without external force. By setting the shape of the trapezoidal block 5112, it is ensured that the trapezoidal block 5112 can be compressed by the inclined surface after being subjected to force, thereby achieving the effect of entering and exiting the clamping hole 5115. Through the combined action of the air pressure tube 5111 and the gas inside it, when the waste material falling on the rotating plate 51 is overheated, the trapezoidal block 5112 is located at a deeper position inside the clamping hole 5115 under the action of air pressure, thereby making the rotating plate 51 unable to rotate. When the temperature of the waste material drops, the trapezoidal block 5112 is reset to move toward the inside of the air pressure tube 5111, thereby enabling the rotating plate 51 to rotate under the action of the gravity of the waste material, so that the waste material falls into the conveying area below, thereby achieving the effect of ensuring the temperature of the waste material.

[0023] During use, on the basis of the first embodiment, when the waste material falling on the rotating plate 51 is hot, the air pressure tube 5111 is heated to expand the gas inside, thereby increasing the pressure inside the air pressure tube 5111, so that the trapezoidal block 5112 moves toward the depth of the clamping hole 5115, so that the straight edge of the trapezoidal block 5112 contacts the clamping hole 5115. At this time, the straight edge of the trapezoidal block 5112 is squeezed and cannot move toward the direction close to the air pressure tube 5111. When the waste material cools down, the gas inside the air pressure tube 5111 cools down and resets. At this time, the trapezoidal block 5112 is reset under the pull of the second spring 5113, so that the trapezoidal block 5112 2 moves to a state where the inclined surface is inside the clamping hole 5115. At this time, when the rotating plate 51 is rotated downward by gravity, the inclined surface of the trapezoidal block 5112 is squeezed, so the trapezoidal block 5112 can move toward the inside of the air pressure tube 5111. At this time, the rotating plate 51 can rotate downward normally. When the rotating plate 51 is rotated upward to reset, the inclined surface above the trapezoidal block 5112 contacts the inner wall of the material box 4, so the trapezoidal block 5112 moves toward the direction of the air pressure tube 5111. When the trapezoidal block 5112 enters the area where the clamping hole 5115 is located, the trapezoidal block 5112 is reset under the drive of the second spring 5113, thereby resetting the device.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
