[0033] The ash treatment device of thermal power plant is a device used to treat the ash produced by thermal power plants. When thermal power plants burn coal or other fuels, they will produce a lot of ash, including bottom ash and fly ash.

[0034] The ash handling device of a thermal power plant includes a slag pit and a conveying mechanism located below the slag pit. Since the bottom of the slag pit has a narrow cross section, when a large volume of ash coke blocks pass through, coke may be stuck, resulting in coke piles at the bottom of the slag pit, forcing the dry slag machine system to be shut down. When the coke piles at the slag pit are serious, the unit may even need to be forced to land. Therefore, the manual coke handling method is not only unsafe, but also affects the economic efficiency of the unit.

[0035] In order to solve the above problems, the utility model proposes an ash crushing device, which aims to provide an ash crushing device that can crush large ash coke blocks. Figures 1 to 4 The present invention is a schematic structural diagram of an embodiment of the ash crushing device provided by the utility model.

[0036] Please refer to Figures 1 to 4 The utility model proposes a slag crushing device 1000, including a slag pit 1, a conveying mechanism 2 and a crushing mechanism 3. The slag pit 1 is formed with a slag inlet 11 and a slag outlet 13. A mounting hole 14 is provided on one side of the slag pit 1. The conveying mechanism 2 is arranged below the slag pit 1. The crushing mechanism 3 is arranged on one side of the slag pit 1. The crushing mechanism 3 is movably provided with a crushing head 31. At least part of the mechanism of the crushing head 31 is penetrated through the mounting hole 14 and is located in the slag pit 1.

[0037] In the technical solution of the utility model, an ash crushing device 1000 and ash processing equipment are proposed, wherein the ash crushing device 1000 includes a slag pit 1, a conveying mechanism 2 and a crushing mechanism 3, a mounting hole 14 is provided on one side of the slag pit 1, and the crushing mechanism 3 is provided with a movable crushing head 31, which is movably inserted into the mounting hole 14 and can move in the slag pit 1. When a larger waste slag coke block is stuck in the slag pit 1 and cannot fall, the crushing head 31 can crush the larger coke block through reciprocating impact, thereby solving the problem of coke stuck in the slag pit 1 and improving production efficiency.

[0038] In order to achieve a more effective crushing effect on the coke block with a larger volume, the crushing head 31 includes a screw portion 312 and a tip portion 311 connected to each other. For details, please refer to Figure 2 and Figure 3 The slag well 1 is formed with a slag passage 12, which is connected to the slag inlet 11 and the slag outlet 13. The tip 311 is located in the slag passage 12. The tip 311 impacts the coke blocks in the slag passage 12, which can achieve a better crushing effect. The design of the tip can concentrate the force on a smaller area and quickly transfer the impact force to the coke blocks. This can improve the efficiency and penetration ability of the crushing head 31. The shape of the tip can reduce the surface area in contact with the coke blocks, thereby reducing the friction and resistance between the coke blocks and the coke blocks. This means that more energy can be transferred to the coke blocks, increasing the power of the impact. The sharp edge of the tip can concentrate the stress and concentrate it on a small area, thereby increasing the local stress of the material and making it easier to penetrate.

[0039] It should be further explained that the crushing head 31 can be driven by a pneumatic cylinder or a hydraulic cylinder, and the present invention does not impose any restrictions on this. In one embodiment of the present invention, the crushing mechanism 3 also includes a sliding seat 32, which is driven by a hydraulic cylinder. Since the crushing head 31 continues to reciprocate in a straight line, the hydraulic drive has the following advantages. First, the hydraulic system has a high power output and carrying capacity, and can provide sufficient force to drive the crushing head 31 for effective crushing operations; secondly, the hydraulic system has a high control accuracy and response speed, and can flexibly adjust the movement speed and force of the crushing head 31 to meet different crushing requirements; in addition, the hydraulic system has a simple structure, is easy to maintain, has a long service life and stable performance, and can improve the working efficiency and reliability of the crushing equipment.

[0040] In order to crush the coke blocks in contact with the screw part 312, the crushing mechanism 3 further includes a driving rotating member 33. For details, please refer to Figure 1 The driving rotating member 33 can drive the crushing head 31 to rotate so that the screw part 312 rotates. The screw part 312 is formed with a spiral groove. When the coke block contacts the screw part 312, the spiral groove will bite the coke block to crush it, thereby preventing the coke block from getting stuck in the screw part 312 and unable to be crushed.

[0041] In order to control the opening and closing of the waste slag flow channel, a shut-off door 4 is provided at the slag outlet 13 of the slag pit 1. For details, please refer to Figure 3The shut-off door 4 is located below the crushing head 31 and is spaced apart from the crushing head 31. The working principle of the shut-off door 4 is to control the opening and closing of the door body through a hydraulic system. When the waste slag flow channel needs to be closed, the hydraulic system will apply pressure to close the door body and ensure the sealing performance. When the waste slag flow channel needs to be opened, the hydraulic system will release the pressure to open the door body and allow the waste slag to flow. The hydraulic shut-off door 4 has the advantages of easy operation, precise control, and reliable sealing. It can be remotely or automatically controlled as needed to improve work efficiency and safety. In addition, the hydraulic shut-off door 4 can also be designed and customized according to actual conditions to meet the waste slag treatment needs of different power plants.

[0042] In one embodiment of the utility model, the distance between the crushing head 31 and the shut-off door 4 is between 50 cm and 70 cm, which can be 50 cm or 70 cm. The utility model does not impose any limitation on this. In one embodiment of the utility model, the distance between the crushing head 31 and the shut-off door 4 is 50 cm. At this time, the coke blocks crushed by the crushing head 31 are not easy to accumulate at the shut-off door 4, thereby causing secondary blockage. Setting the distance between the crushing head 31 and the shut-off door 4 to 50 cm can also further control the overall height of the equipment, thereby reducing the overall size of the equipment.

[0043] To further improve the crushing efficiency, the ash crushing device 1000 includes two slag pits 1 and two crushing mechanisms 3. For details, please refer to Figure 1 Each driving rotating member 33 drives two transmission members 34, and the two transmission members 34 drive the two crushing heads 31 to achieve rotation.

[0044] The utility model also proposes an ash processing equipment, which includes an ash crushing device 1000. The specific structure of the ash crushing device 1000 refers to the above embodiment. Since the ash processing equipment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0045] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
