Description
Technical Field
[0001] The utility model belongs to the technical field of furnace ash treatment, in particular to a radioactive waste gasification furnace ash treatment device. Background Art
[0002] In daily life, the gasification furnace used to process daily waste materials only needs to wait for the ash to accumulate to a certain extent before simple manual treatment. However, the ash produced by radioactive waste materials is still radioactive even after gasification and cracking, and the human body cannot touch it at will. It must be handled in a closed manner. The usual automated ash handling device allows the ash to flow out from the bottom of the furnace, then collects the ash in plastic bags, and finally takes it to a specific place for burial. In this process, since the ash produced by the waste materials that have just undergone gasification and cracking is relatively hot, it will burn the plastic bag directly, causing the ash to flow out, which is easy to cause harm to the human body. Moreover, the ash flowing directly from the top will float in the air, which is not convenient to collect and treat. Therefore, it is necessary to design an integrated device that can handle ash in a closed space, does not directly contact the human body, and can cool the ash to solve the problem of plastic bags being damaged due to the ash being too hot, thus causing harm to the human body. Utility Model Content
[0003] In view of the above technical problems, the utility model provides an integrated device that can process ash in a closed space without direct contact with the human body, and can perform ash cooling treatment to solve the problem of plastic bags being damaged due to overheated ash, thereby causing harm to the human body.
[0004] In order to solve the above technical problems, a radioactive waste gasification furnace ash treatment device described in the utility model includes an operation box, a gasifier, and a water tank. The operation box and the water tank are fixedly connected. A cooling layer is fixedly connected to the outer side of the lower part of the gasifier. The bottom discharge port of the gasifier is connected to the feeding port of the auger conveyor. The output end of the auger conveyor is connected to the top of the operation box through a pipeline. The auger conveyor is driven by a first motor. An operation hole is opened on the side of the operation box and a conveyor belt is arranged inside. Protective gloves are fixedly connected to the operation hole. One end of the conveyor belt extends to the outside of the operation box and is fixedly connected to a support frame at the bottom. The support frame is fixedly connected to a second motor. The conveyor belt is driven by the second motor. The bottom end of the cooling layer is fixedly connected to a water inlet pipe and the top is fixedly connected to a water outlet pipe. The other end of the water inlet pipe is fixedly connected to the output end of a water pump. The input end of the water pump is connected to the water tank through a water pipe, and the other end of the water outlet pipe passes through a water injection port and extends into the water tank.
[0005] Furthermore, an ash bucket is movably placed above the conveyor belt, and a plastic bag is placed in the ash bucket.
[0006] Furthermore, a control box is installed on the front of the operation box, and the first motor, the second motor and the water pump are controlled by the control box.
[0007] Furthermore, a box door is hingedly connected to the side of the operation box located above the conveyor belt.
[0008] Furthermore, an observation port is provided on the side of the water tank.

[0010] 1. The utility model can achieve the purpose of cooling the ash by fixing a cooling layer on the outer side of the lower end of the gasifier, so that the ash at the bottom of the gasifier can be dissipated by the flowing water in the cooling layer. By arranging the water inlet at the bottom of the cooling layer and the water outlet at the top of the cooling layer, the water flow speed can be slowed down, the water can fill the entire cooling layer, and the cooling effect can be improved. By arranging the discharge port at the bottom of the gasifier to be connected with the feed port of the auger conveyor, the cooled ash can be transported to the operation box and further cooled at the same time. By arranging a conveyor belt inside the operation box, the ash can be packed in the operation room and then sent out by the conveyor belt to avoid direct contact with the human body. By arranging an operation hole on the side of the operation box, the left and right sides of the operation hole are respectively sealed and connected with protective gloves to avoid direct contact with the human body. Through the operation hole and the protective gloves, the plastic bag filled with ash can be packed and tied tightly manually, and the ash bucket lid can be covered to further protect the human body.
[0011] 2. The utility model places an ash bucket above the conveyor belt, and a plastic bag is placed in the ash bucket, so that the ash can be packaged conveniently after it is collected, thereby reducing the labor intensity.
[0012] 3. The utility model has a hinged box door on the side of the operating box and located above the conveyor belt, so that the ash bucket can be easily transported in and out of the operating box through the crawler belt.
[0013] 4. The utility model provides an observation port on the surface of the water tank, so that the water level in the water tank can be checked at any time, which is convenient for timely adding water when the water is insufficient to ensure the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0018] The utility model will be further described below in conjunction with the accompanying drawings.
[0019] like Figure 1 , 2 3 shows a radioactive waste gasification furnace ash treatment device, comprising an operation box 1, a gasifier 2, and a water tank 8. The operation box 1 and the water tank 8 are fixedly connected as a whole. In order to cool the ash at the bottom of the gasifier 2, a cooling layer 3 is fixedly connected to the outer side of the lower part of the gasifier 2. In order to transport the cooled ash to the operation box 1, the bottom discharge port of the gasifier 2 is fixedly connected to the feed port of the auger conveyor 4 by bolts, and the output end of the auger conveyor 4 is connected to the top of the operation box 1 through a pipeline. The auger shaft is fixedly connected through a coupling first motor 7. In order to facilitate manual assistance for post-ash packaging processing, an operation hole 11 is opened on the side of the operation box 1. Protective gloves are fixedly connected to the operation hole 11 to isolate and protect the operator. In order to facilitate the transportation of ash out of the operation box 1. A conveyor belt 12 is arranged inside the operation box 1. One end of the conveyor belt 12 extends to the outside of the operation box 1 and is fixedly connected to a support frame 18 at the bottom. The support frame 18 is fixedly connected to a second motor 13. The second motor 13 is connected to a belt between a roller on the conveyor belt 12. The belt rotation drives the roller to rotate, thereby driving the conveyor belt 12 to rotate. In order to ensure that the water flow in the cooling layer 3 is in a flowing state and improve the cooling effect, a water inlet pipe 5 is fixedly connected to the bottom of the cooling layer 3 and a water outlet pipe 15 is fixedly connected to the top. In order to save water resources and avoid waste, the other end of the water inlet pipe 5 is fixedly connected to the output end of the water pump 7. The input end of the water pump 7 is connected to the water tank 8 through a water pipe. The other end of the water outlet pipe 15 passes through the water injection port 17 and extends into the water tank 8, thereby forming a water circulation system.
[0020] In order to conveniently receive and pack the furnace ash in the operation box 1 , an ash container 14 is movably placed above the conveyor belt 12 , and a plastic bag is placed in the ash container 14 .
[0021] In order to uniformly control the device and improve the automation level of the device, a control box 10 is installed on the front of the operation box 1 , and the first motor 6 , the second motor 13 , and the water pump 7 are controlled by the control box 10 .
[0022] In order to facilitate the ash container 14 to enter and exit the operation box 1 and to facilitate maintenance of the device, a box door 16 is hinged on the side of the operation box 1 above the conveyor belt 12.
[0023] In order to ensure that the water level in the cooling layer 3 is sufficient and enhance the cooling effect, an observation port 9 is opened on the side of the water tank 8 to facilitate personnel to observe the water level and replenish water in time.
[0024] It should be noted that the utility model sets a thermometer and a refrigeration device in the water tank 8, so as to observe the water temperature in the water tank at any time. When the water temperature exceeds 40 degrees Celsius, refrigeration is performed to ensure the cooling effect.
[0025] The specific working process of the utility model is as follows:
[0026] In the process of treating radioactive waste in the gasifier 2, a large amount of ash will be generated, and the ash will fall to the lower end of the gasifier 2. By arranging a cooling layer 3 at the lower end of the gasifier 2, the ash at the bottom can conduct heat away. By arranging a water inlet at the bottom of the cooling layer 3 and a water outlet at the top, it can be ensured that the cooling layer 3 is always filled with water and the water is in a circulating state, thereby enhancing the cooling effect. The discharge port at the bottom of the gasifier 2 is connected to the feed port of the auger conveyor 4. The end of the auger conveyor 4 is connected to the operating box 1 through a pipeline, so that the cooled ash can be transported into the operating box 1. There is a conveyor belt 18 inside the operating box 1, and an ash bucket 14 is placed on the conveyor belt 18. A plastic bag is placed in the ash bucket 14. When the plastic bag is filled with ash, the operator packs and seals it through the protective gloves on the operating hole 11, and then sends it out of the operating box 1 through the conveyor belt 18. The operating box 10 is set on the front of the operating box 1 to control the first motor 6, the second motor 13 and the water pump 7, thereby improving the degree of automation of the device. By connecting the input end of the water pump 7 to the water tank 8 and the output end to the water inlet pipe 5, the water outlet pipe 15 passes through the water injection port 1 and extends into the water tank 8, thereby realizing water recycling and avoiding the waste of water resources. At the same time, the water level is monitored through the observation port 9 set on the surface of the water tank 8, and the water source is replenished in time to ensure the cooling effect. According to the above steps, the ash treatment can ensure that the ash will not burn the plastic bag, causing the ash to be scattered, avoiding harm to the human body, and at the same time reducing the intensity of manual labor and improving work efficiency.
