Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cracking kettles, in particular to a cracking kettle system for processing solid waste. Background Art
[0002] A cracking kettle is a device used for chemical reactions, mainly for cracking reactions, especially in the fields of petrochemicals and materials science. Its main function is to crack macromolecular compounds into smaller molecules by heating. The working principle of the cracking kettle is to heat the raw materials to a high temperature to cause a thermal cracking reaction. At high temperatures, macromolecules such as petroleum and plastics are decomposed into smaller molecules, such as olefins and aromatics. The products after the reaction are cooled and separated to obtain the desired chemicals or fuels. Cracking kettles are usually used to produce basic chemical raw materials such as ethylene and propylene or to convert waste such as plastics into usable fuels or raw materials. Cracking kettles are also used in the conversion of biomass energy.
[0003] In the prior art, the furnace of the cracking kettle is mostly in direct contact with the supporting roller by the cylinder, which easily leads to excessively high temperature of the supporting roller, causing the grease in the supporting roller bearing to melt and lose its lubricating effect. In addition, because there is a weld in the cylinder itself, the rotation is not stable when it contacts and rotates with the supporting roller; the heat-insulating shell outside the furnace and the heat-insulating materials in the burning furnace are mostly castables such as refractory cement, refractory stone, refractory sand and refractory bricks. This method has slow heat dissipation and heavy weight, resulting in a long cooling time after the cracking kettle stops working, and it is also inconvenient to replace the furnace; when the cracking kettle is in use, the fire situation will be observed through the observation port. Usually, the observation port of the cracking kettle is mostly open to the outside, and there is a lack of measures to shield and protect the observation port, which makes it easy for the operator to be affected by heat radiation when observing the fire situation through the observation port, thereby increasing the danger of the operator's operation.

[0035] The present invention is further described in detail below in conjunction with the embodiments:
[0036] Example 1
[0037] like Figure 1-6 As shown, the utility model provides a cracking kettle system for treating solid waste, including a furnace chamber 1, a furnace core 4, two support rings 5, two support wheels 1 2, and two support wheels 201.
[0038] The furnace core 4 is arranged above the furnace cavity 1; two support rings 5 are respectively fixedly connected to the two ends of the furnace core 4; two support wheels 2 are symmetrically installed on both sides of one end of the furnace cavity 1, and the two support wheels 2 are abutted against one of the support rings 5; two support wheels 201 are installed on both sides of the other end of the furnace cavity 1, and the two support wheels 201 are abutted against the other support ring 5.
[0039] In this embodiment, the cracking raw material can be added to the interior of the furnace 4 for cracking. The furnace 4 is located on the furnace chamber 1. The raw material in the furnace 4 can be heated and cracked by igniting in the furnace chamber 1. The support ring 5 is a component processed by a lathe, and the surface roughness, roundness and cylindricity are all guaranteed. Therefore, the support ring 5 is fixedly connected to the furnace 4 and used in conjunction with the support wheel 1 2 and the support wheel 201, which can make the cracking kettle run more smoothly. In addition, by adopting the support ring 5, the heat inside the furnace 4 can be prevented from being transferred to the support wheel 1 2 and the support wheel 201 to affect their service life, which can further improve the use efficiency of the equipment and reduce the failure rate of the equipment.
[0040] like Figure 1-6 As shown, in this embodiment, preferably, a positioning groove engaged with the support ring 5 is provided on the second support wheel 201. Since the support ring 5 is fixedly connected to the surface of the furnace 4, when the furnace 4 is running, the support ring 5 is also running, and since the second support wheel 201 is provided with a positioning groove engaged with the surface of the support ring 5, the support ring 5 can limit the operation of the furnace 4 when engaging with the second support wheel 201, so that the furnace 4 can make the operation of the cracking kettle more stable under the cooperation of the two 5 and the support wheel, thereby improving the production efficiency of the equipment, and the use effect is better.
[0041] like Figure 1-6 As shown, preferably, it also includes an insulation shell 3, which is fitted with the furnace 4, and the two sides of the insulation shell 3 are respectively fixedly connected to the two sides of the furnace chamber 1. The insulation material in the insulation shell 3 adopts an insulation module of aluminum silicate insulation cotton, which has the advantages of high temperature resistance, fast heat dissipation, and light weight. It can be used in conjunction with the operation of the furnace 4 to play a good insulation role. The insulation shell 3 and the furnace 4 are fitted together to have a good heat collection effect, and the insulation shell 3 also protects the operating personnel to avoid direct accidental touch and cause harm to the workers.
[0042] like Figure 1-6 As shown, preferably, at least one observation port 101 is provided on the furnace chamber 1. During the switching process of the cracking furnace, the time for observing the fire is very important. By providing the observation port 101 on the furnace chamber 1, the fire in the furnace chamber 1 can be observed through the observation port 101. Generally, the observation time should be of appropriate length and should not be too long or too short, otherwise the safety and reliability of the switching process may be affected. Therefore, the observation port 101 can be blocked when the fire is not observed to avoid more thermal radiation pollution.
[0043] like Figure 1-6 As shown, preferably, it also includes a "U"-shaped plate 8 and a baffle 9, wherein the "U"-shaped plate 8 is installed on the outside of the observation port 101; and a sliding groove 801 movably connected to the baffle 9 is opened on the "U"-shaped plate 8. The "U"-shaped plate 8 is installed on the outer side of the observation port 101 and is used in conjunction with the baffle 9. The "U"-shaped plate 8 is "U"-shaped. When the baffle 9 is used in conjunction with sliding, one end of the baffle 9 can enter the interior of the sliding groove 801 for limiting, so that the baffle 9 can block the observation port 101 more tightly. When it is necessary to observe the fire in the furnace chamber 1, the baffle 9 can be moved away, which is convenient for the operator to observe the fire. Since the fire observation time is appropriate, when the fire is not observed, the baffle 9 can be blocked on one side of the observation port 101, thereby blocking the high temperature and preventing the heat radiation generated in the furnace chamber 1 from causing harm to the operators. The baffle 9 can play a protective role to a certain extent. A sliding groove 801 is provided on the "U"-shaped plate 8. The baffle 9 is used by sliding in the sliding groove 801, which can make the baffle 9 more flexible when pushed by the operator for use, and is convenient to operate.
[0044] like Figure 1-6As shown, preferably, the two ends of the baffle 9 are respectively installed with limit blocks 901, and the two sides of the "U"-shaped plate 8 are provided with limit sliding grooves 802 respectively connected to the two limit blocks 901 in a sliding manner. Since the limit blocks 901 are installed at the two ends of the baffle 9, the width of the two limit blocks 901 is smaller than the width of the baffle 9, so when the baffle 9 is pushed, the limit blocks 901 only slide inside the limit sliding grooves 802, and when the limit blocks 901 installed below are inside the sliding limit sliding grooves 802, since the baffle 9 is wider than the limit blocks 901, the baffle 9 can only slide inside the sliding grooves 801, and the baffle 9 will not be offset and slid out when pushed. By installing two limit blocks 901, when the baffle 9 is pulled outward, the baffle 9 cannot be directly pulled out, which can avoid the inconvenience of the baffle 9 being directly pulled out for the operator to install, and can improve the efficiency of the operator's work.
[0045] like Figure 1-6 As shown, preferably, a handle 902 is fixedly mounted on the surface of the baffle 9. The handle 902 mounted on the surface of the baffle 9 can play an auxiliary role when the baffle 9 is pushed and used, so that the baffle 9 can be slidably used.
[0046] like Figure 1-6 As shown, preferably, it also includes a silo door 6 and an exhaust pipe 7; the silo door 6 is movably installed at one end of the furnace 4; the exhaust pipe 7 is connected to the other end of the furnace 4. When the raw material is cracked, the raw material can be added to the furnace 4 by opening the silo door 6, and a variety of combustion aids and additives can be added to ensure that the subsequent heating and cracking process can be better carried out. When the raw material starts to be heated and cracked, the material in the furnace 4 is heated by burning gas or fuel oil, and the temperature reaches the high temperature and high pressure state required for the cracking reaction, and the released gas is discharged through the exhaust pipe 7.
[0047] The working principle of the pyrolysis kettle system for treating solid waste is described in detail below.
[0048] like Figure 1-6As shown, when in use, by opening the silo door 6 and adding raw materials into the interior of the furnace 4, the furnace chamber 1 is burned. At this time, the heat generated in the furnace chamber 1 is conducted to the furnace chamber 4, and the furnace chamber 4 runs to crack the raw materials inside. At this time, the support rings 5 installed at both ends of the furnace chamber 4 can rotate during the operation, and the support rings 5 can be engaged with the supporting wheel. Therefore, when the furnace chamber 4 is in operation, the support rings 5 can prevent the furnace chamber 4 from directly contacting the supporting wheel. Since the heat inside the furnace chamber 4 will be conducted to the surface, the furnace chamber 4 will directly contact the supporting wheel, resulting in excessive temperature, causing the grease in the supporting wheel bearing to melt and lose its lubricating effect. By providing a positioning groove on the surface of the supporting wheel 201, the positioning groove can engage with one of the supporting rings 5 in operation, so that the operation of the furnace chamber 4 can be limited to prevent the furnace chamber 4 from deviating during operation, and the support rings 5 are The surface roughness, roundness and cylindricity of the parts processed by the lathe are all guaranteed. Therefore, under the operation of the furnace core 4, the cracking kettle runs more smoothly. By setting the support ring 5, the furnace core 4 can be prevented from directly contacting with the support wheel at high temperature, which can further increase the service life of the support wheel and reduce the failure rate of the equipment. During the cracking process, it is necessary to observe the fire condition in the furnace chamber 1. Observing the fire condition is an important step in cracking. The operator can observe the fire condition through the observation port 101. When observing the fire condition, the handle 902 can be used to move the baffle 9 to one side, and the fire condition inside the furnace chamber 1 can be observed through the observation port 101. After the observation, the handle 902 can be used to push the baffle 9 back to its original position, thereby blocking the high temperature and avoiding the direct opening of the observation port 101 to cause the operator to be harmed by heat radiation, which can play a protective role.
[0049] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
