Description

Technical Field

[0001] This utility model relates to the technical field of waste tire processing, and in particular to an environmentally friendly waste tire pyrolysis furnace. Background Technology

[0002] With the rapid development of the automobile industry, the number of waste tires is increasing day by day. The random disposal of waste tires not only occupies a lot of land resources, but also causes serious environmental pollution. Waste tire pyrolysis technology is an effective way to recycle resources. Through high-temperature pyrolysis, waste tires are converted into valuable products such as fuel oil and carbon black. The thermal pyrolysis of waste tires refers to the process of decomposing them into solid carbon under anaerobic or hypoxic conditions and at appropriate temperatures. Its products are mainly fuel oil, pyrolysis gas, carbon black, etc. Therefore, there is a special need for an environmentally friendly waste tire pyrolysis furnace.

[0003] However, existing waste tire processing in pyrolysis furnaces generates a large amount of flue gas and oil vapor. Due to the high temperature inside the furnace, these gases contain small amounts of solid particles, primarily carbon black. Direct discharge of these particles would be a waste of resources. Current technology uses filters to block the carbon black in the flue gas and oil vapor. After the flue gas and oil vapor are discharged, the filter is vibrated to remove the carbon black adhering to it. However, as the flue gas and oil vapor continue to be discharged, carbon black continuously adheres to the filter surface. Over time, this carbon black easily clogs the filter, affecting the discharge of flue gas and oil vapor, hindering continuous vibration of the filter, causing secondary pollution due to improper waste disposal, low energy efficiency, high production costs, and incomplete pyrolysis, thus affecting product quality. Furthermore, existing pyrolysis furnaces lack devices for pulverizing waste tires, or the pulverizing devices cannot perform secondary pulverization, resulting in large pieces of waste tires that compromise the pyrolysis effect. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly waste tire pyrolysis furnace to address the problems mentioned in the background art. Existing pyrolysis furnaces generate large amounts of flue gas and oil vapor during waste tire processing. Due to the high temperature inside the furnace, these gases contain small amounts of solid particles, primarily carbon black. Direct discharge of these particles leads to resource waste. Current technologies use filters to block the carbon black from the flue gas and oil vapor. After the gases are discharged, the carbon black adhering to the filters is removed. However, as the flue gas and oil vapor continue to be discharged, carbon black continuously adheres to the filter surface. Over time, this easily clogs the filters, affecting the discharge of flue gas and oil vapor, hindering continuous vibration of the filters, causing secondary pollution due to improper waste disposal, low energy efficiency leading to high production costs, and incomplete pyrolysis affecting product quality. Furthermore, existing pyrolysis furnaces lack a device for pulverizing waste tires, or the pulverizing device cannot perform secondary pulverization, resulting in large waste tire pieces that compromise the pyrolysis effect.

[0014] 2. This environmentally friendly waste tire pyrolysis furnace, by setting up a crushing and cleaning component, can effectively solve the problem in existing technologies where carbon black continuously adheres to the surface of the filter screen during the continuous emission of flue gas and oil gas, which easily causes the filter screen to become clogged after a period of time, affecting the emission of flue gas and oil gas.

[0015] 3. This environmentally friendly waste tire pyrolysis furnace uses a cleaning steel brush installed below the filter screen.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This utility model provides a technical solution: an environmentally friendly waste tire pyrolysis furnace, including a workbench 1, a support frame 2 fixedly installed at the bottom of the workbench 1, a placement groove 3 opened on the outer side of the workbench 1, a through hole 4 opened at the top of the workbench 1, a pyrolysis furnace body 5 fixedly installed at the top of the workbench 1, a temperature sensor 6 and a control switch 7 fixedly installed on the outer wall of the pyrolysis furnace body 5, a discharge plate 8 and a handle 9 on the outer side of the pyrolysis furnace body 5, a filter screen 10 inside the pyrolysis furnace body 5, a cover 11 fixedly installed at the top of the pyrolysis furnace body 5, an installation hole 12 opened at the top of the cover 11, a lifting ring 17 fixedly installed at the top of the cover 11, a discharge pipe 13 fixedly installed inside the cover 11, an electromagnetic heating device 14 inside the pyrolysis furnace body 5, a second installation hole 15 opened on the outer side of the pyrolysis furnace body 5, a crushing and cleaning component 16 fixedly installed at the bottom inside the pyrolysis furnace body 5, and a heating sleeve 18 inside the electromagnetic heating device 14.

[0025] Furthermore, the combination of temperature sensor 6 and control switch 7 adopts an inclined structure for easy operation by staff. The discharge plate 8 and handle 9 are located on both sides of the outer wall of the pyrolysis furnace body 5. The vertical cross-section of the discharge pipe 13 is "L" shaped. Through the cooperation of temperature sensor 6 and control switch 7, the temperature inside the furnace can be monitored in real time, and the electromagnetic heating device 14 can be activated to make the inside of the pyrolysis furnace body 5 heated to an oxygen-free or oxygen-deficient environment for pyrolysis of waste tires. At the same time, excess carbon black falls under the action of gravity, and the discharge plate 8 is located at the bottom of the pyrolysis furnace body 5, so that some of the falling carbon black falls onto the discharge plate 8 for collection.

[0026] Furthermore, the discharge pipe 13 is fixedly connected to the cover 11 through the mounting hole 12, and the handle 9 is fixedly connected to the filter screen 10. By setting the discharge pipe 13 with an "L" shaped structure, the flue gas and oil gas can be discharged into the next process through the pipe, while preventing debris from falling into the discharge pipe 13.

[0027] Furthermore, the size of the handle 9 is consistent with the size of the mounting hole 15. The electromagnetic heating device 14 and the heating sleeve 18 are compatible. The electromagnetic heating device 14 and the heating sleeve 18 are located below the filter screen 10, and the electromagnetic heating device 14 and the heating sleeve 18 do not contact each other with the crushing and cleaning component 16. The operator pulls up the lifting ring 17 and pulls out the filter screen 10, and puts the waste tire into the heating sleeve 18. By setting the handle 9 and the filter screen 10, and the handle 9 and the filter screen 10 are fixedly connected, the filter screen 10 can be pulled out together by pulling the handle 9, realizing the quick replacement and installation of the filter screen 10. The operation is simple and convenient. At the same time, the electromagnetic heating device 14 and the heating sleeve 18 do not contact each other with the crushing and cleaning component 16, and will not affect the crushing and cleaning component 16 to crush the waste tire.

[0028] Furthermore, the crushing and cleaning assembly 16 includes a motor 1601, a fixed roller 1602, a mounting bracket 1603, crushing blades 1604, a support column 1605, and a cleaning steel brush 1606. The motor 1601 is fixedly installed at the bottom inside the workbench 1. The fixed roller 1602 is fixedly installed at the output end of the motor 1601. The mounting bracket 1603 is fixedly installed at the top of the fixed roller 1602. The rotating mounting bracket 1603 drives the crushed waste tire blocks that fall into the bottom of the pyrolysis furnace body 5, causing secondary crushing of the waste tire blocks and further ensuring the cracking of the waste tires. To achieve the desired effect, a pulverizing blade 1604 is fixedly installed on the top of the mounting bracket 1603, and a support column 1605 is fixedly installed on the top of the pulverizing blade 1604. A cleaning steel brush 1606 is fixedly installed on the outside of the support column 1605 by bolts. The pulverizing blade 1604 has three identical blades, and the three pulverizing blades 1604 are arranged in a ring on the top of the mounting bracket 1603. When flue gas and oil gas are emitted, the cleaning steel brush 1606 removes the carbon black attached to the lower surface of the filter screen 10. The carbon black will not cause the filter screen to be blocked and will not affect the emission of flue gas and oil gas.

[0029] Furthermore, the size of the cleaning steel brush 1606 is the radius of the filter screen 10. The cleaning steel brush 1606 contacts the filter screen 10, which makes the cleaning efficiency of the filter screen 10 higher and facilitates continuous cleaning of the filter screen 10.

[0030] Furthermore, the motor 1601 is adapted to the through hole 4. The motor 1601 passes through the workbench 1 and extends to the top of the workbench 1 and is fixedly connected to the fixed roller 1602, so that the waste tires are decomposed in the pyrolysis furnace body 5 under anoxic or hypoxic conditions, which improves the decomposition efficiency and has high practicality.

[0031] Working principle: During operation, the operator uses the machine to hang a pair of lifting rings 17 to lift the cover 11, and pulls out the filter screen 10 through the handle 9. The waste tire is then placed into the heating sleeve 18, and the filter screen 10 is returned to its original position. The operator then activates the electromagnetic heating device 14, which heats the heating sleeve 18 to pyrolyze the waste tire. This avoids direct contact between the electromagnetic heating device 14 and the waste tire, preventing the tire from sticking to the device. Furthermore, the operator can monitor the furnace temperature in real time through the temperature sensor 6, facilitating timely adjustments. In response to special circumstances, the operator simultaneously starts motor 1601, driving fixed roller 1602, which in turn drives mounting bracket 1603 to rotate. This rotates the pulverized waste tire blocks that fall to the bottom of the pyrolysis furnace body 5, causing secondary pulverization of the waste tire blocks and further ensuring the pyrolysis effect of the waste tires. Simultaneously, the pulverizing blades 1604 rotate, and the cleaning steel brush 1606 rotates, contacting the filter screen 10. At this time, the waste tires generate flue gas and oil vapor during heating in the heating sleeve 18 inside the pyrolysis furnace body 5. Under the action of the pulverizing blades 1604, the waste tires are processed and pulverized, thus... The magnetic heating device 14 heats the shredded waste tires more evenly, generating a large amount of flue gas and oil vapor. Due to the high temperature inside the pyrolysis furnace, the flue gas and oil vapor contain a small amount of solid particles, mainly carbon black. The filter screen 10 blocks the carbon black from the flue gas and oil vapor. During flue gas and oil vapor discharge, the cleaning steel brush 1606 rotates and contacts the filter screen 10 to remove the carbon black adhering to its lower surface. The carbon black falls under gravity, and since the discharge plate 8 is located at the bottom of the pyrolysis furnace body 5, some of the falling carbon black is collected on the discharge plate 8. This reduces waste of resources. Finally, the flue gas and oil gas are discharged through the discharge pipe 13 and enter the next process. After the pyrolysis is completed, the staff will pull the handle 9 to remove the filter screen 10 and replace it. At the same time, the discharge plate 8 will be pulled to recycle the collected carbon black. Finally, the exterior and interior of the entire pyrolysis furnace body 5 can be cleaned to ensure that most of the carbon black in the furnace is recycled. This realizes the resource-based treatment of waste residue, reduces the occupation and pollution of solid waste in the environment, creates additional economic benefits, and reduces the adverse impact on the surrounding environment and atmosphere. It has high practicality.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
