Description
Technical Field
[0001] The invention relates to the technical field of solid waste thermal cracking, and in particular to a novel thermal cracking furnace material foaming and crushing device. Background Art
[0002] In the field of solid waste (hereinafter referred to as "solid waste") thermal cracking technology, thermal cracking furnaces are used to crack solid waste. In the high temperature and oxygen-free environment of the thermal cracking furnace, the solid waste undergoes cracking reaction to achieve the reduction and harmless treatment of the solid waste. The thermal cracking furnace is equipped with multiple functional components, such as a crushing device. In the treatment of various solid wastes, some solid waste materials often produce foaming phenomena and rapid volume expansion along with the cracking reaction, which has a very adverse effect on the smooth progress of the solid waste thermal cracking reaction, such as: expansion is the increase in volume leading to furnace blockage, and the solid waste cannot be normally transported in the cracking furnace. At present, although there are some devices for crushing foaming solid waste in use, due to the high temperature environment of up to several hundred degrees in the cracking furnace, the crushing blocks on the crushing device that are located in the furnace and directly contact the foaming solid waste will produce wear and thermal deformation after a period of use, and need regular maintenance, repair and replacement. It is very difficult to remove the deformed crushing blocks from the crushing device as a whole, especially the parts with threaded connections. Due to the high temperature environment, the threaded connection parts are easily damaged and deformed, which greatly increases the difficulty of disassembly. Therefore, many users are unable to maintain, repair and replace the crushing devices normally and have to let the crushing devices work "with defects", which seriously affects the crushing effect of foaming solid waste, and further affects the quality and progress of solid waste treatment. Many users have to replace the crushing devices as a whole, which greatly increases the use cost of the thermal cracking equipment.
[0003] In order to avoid the above situation, it is very important to design a new type of thermal cracking furnace material foaming and crushing device. Summary of the invention
[0004] In view of the foaming phenomenon generated during the cracking process of some types of solid waste, the purpose of the present invention is to provide a new type of thermal cracking furnace material foaming and crushing device, which has a simple structure, reasonable design, practicality and reliability, ensures the stability and reliability of the thermal cracking equipment, is not affected by the wear and deformation of the crushing blocks and is easy to disassemble, making the maintenance, repair and replacement of the crushing device very convenient, highly practical, and easy to promote and use.
[0005] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical scheme: a new type of thermal cracking furnace material foaming and crushing device, comprising: a crushing block (1), two lifting rods (2), two gas sealing cover devices (3), a fixed bracket (4), and two cylinders (5), wherein: the fixed bracket (4) and the gas sealing cover device (3) are fixed on the furnace shell, the crushing block (1) and the lifting rod (2) are connected together by a pin shaft with a hole (1-4), and the lifting rod (2) passes through the gas sealing cover device (3) and is connected to the cylinder (5) fixed on the fixed bracket (4).

[0007] As a preferred embodiment of the present invention, the crushing blade plate (1-1) has two rectangular shafts (1-1-1) on the crushing blade plate (1-1).
[0008] As a preferred embodiment of the present invention, the first connecting plate (1-2) has a plurality of rectangular holes (1-2-1) and a plurality of circular holes (1-2-2) and a rectangular shaft (1-2-3) on the first connecting plate (1-2).

[0010] As a preferred embodiment of the present invention, the lifting rod (2) has a circular hole (2-1) at one end of the lifting rod (2) and a threaded hole (2-2) on the end surface of the other end.
[0011] Beneficial effects of the present invention: The present device can effectively crush solid waste that foams and expands rapidly in volume during the cracking process, avoiding the occurrence of furnace blockage and the inability to normally transport solid waste, so that the cracking of solid waste can proceed smoothly. At the same time, it ensures that the crushing blocks are not affected by wear and deformation and are still easy to disassemble, making the maintenance, repair and replacement of the crushing device very convenient, and only needs to replace the parts that are severely damaged and deformed, avoiding the replacement of the entire crushing device, reducing the use cost of the equipment, ensuring the quality of the cracking furnace to treat solid waste, and improving the reliability of the cracking furnace equipment.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7The present specific embodiment adopts the following technical scheme: a novel thermal cracking furnace material foaming and crushing device, comprising: a crushing block (1), two lifting rods (2), two gas sealing cover devices (3), a fixed bracket (4), and two cylinders (5), wherein: the fixed bracket (4) and the gas sealing cover device (3) are fixed on the furnace shell, the crushing block (1) and the lifting rod (2) are connected together by a pin with a hole (1-4), and the lifting rod (2) passes through the gas sealing cover device (3) and is connected to the cylinder (5) fixed on the fixed bracket (4); as for the composition of the crushing block (1), the rectangular shaft on the first connecting plate (1-2) The first connecting plate (1-2) and the second connecting plate (1-3) are inserted into the corresponding rectangular holes (1-3-1) on the second connecting plate (1-3), and the rectangular shafts (1-3-3) on the second connecting plate (1-3) are inserted into the corresponding rectangular holes (1-2-1) on the first connecting plate (1-2), so that the first connecting plate (1-2) and the second connecting plate (1-3) form a closed rectangular frame, and on the two sides of the rectangular frame, there are a plurality of rectangular holes (1-2-1) and rectangular holes (1-3-1) corresponding to each other, and the rectangular shafts (1-1-1) of the plurality of crushing blade plates (1-1) are respectively inserted into the corresponding rectangular holes (1-2-1) and rectangular holes (1-3-1). The plurality of circular holes (1-2-2) on the first connecting plate (1-2) and the plurality of circular holes (1-3-2) on the second connecting plate (1-3) correspond to each other, and the plurality of pin shafts with holes (1-4) pass through the corresponding circular holes (1-2-2) and the circular holes (1-3-2) to connect the first connecting plate (1-2) and the second connecting plate (1-3) into a whole, wherein two pin shafts with holes (1-4) also pass through the circular holes (2-1) on the lifting rod (2), so that a complete crushing block (1) is formed, and the crushing block (1) is also connected to the lifting rod (2); the lifting rod (2) is connected to the cylinder (5) fixed on the fixed bracket (4) through a threaded hole (2-2) on the end surface of the other end. Under the action of the cylinder (5), the crushing block (1) is moved up and down by the lifting rod (2), so that the foamed solid waste passing under the crushing block (1) can be crushed.
[0022] Through the specific implementation, it can be seen that the crushing device of the present invention, the part in the cracking furnace, the crushing block (1), is formed by inserting and connecting a rectangular shaft and a rectangular hole, and a pin shaft with a hole and a round hole. The crushing block (1) and the lifting rod (2) are also connected by inserting a pin shaft with a hole into a round hole. The above-mentioned rectangular hole and the rectangular shaft, the pin shaft with a hole and the round hole are matched with a sufficiently large gap, so that the shaft and the hole will not be difficult to separate due to the high temperature in the furnace and the deformation and wear during use, thereby avoiding the problems caused by the threaded connection method. When the crushing device is maintained, repaired and replaced, it is very convenient to disassemble. It only needs to remove the pin shaft with a hole (1-4) from the The first connecting plate (1-2) and the second connecting plate (1-3) are taken out of the circular hole, and the rectangular shafts on the first connecting plate (1-2) and the second connecting plate (1-3) are respectively pulled out from the rectangular holes on each other, so that the worn and deformed crushing blade plate (1-1) can be removed, and the damaged crushing blade plate (1-1) can be replaced, and then reassembled according to the method described above. Since the disassembled parts are small in size and light in weight, the entire maintenance operation can also be carried out in the furnace, realizing quick and convenient maintenance, repair and replacement of the crushing device, shortening the maintenance time and the shutdown time. At the same time, since only the severely deformed and worn parts are replaced instead of replacing the entire crushing block, the cost is greatly reduced.
[0023] Compared with the crushing device commonly used in the market, the present invention ensures that when the solid waste material foams and expands in volume during operation of the thermal cracking furnace, the foaming material can be quickly and effectively crushed, so that the solid waste material always maintains a crushed and discrete state during the cracking process, ensuring that the material can be continuously cracked and transported along a normal path, ensuring the treatment quality of the solid waste by the cracking furnace, and improving the reliability of the operation of the cracking furnace equipment. At the same time, it ensures that the crushing blocks that contact with the solid waste and crush the solid waste are easy to disassemble and replace, making the maintenance, repair and replacement of the crushing device very convenient, and there is no need to replace the crushing device as a whole, only the worn parts need to be replaced, which greatly reduces the use and operation cost of the equipment, and therefore has a broad market application prospect.
