Description

Technical Field

[0001] This utility model relates to the technical field of pyrolysis furnace equipment, specifically a gas pyrolysis furnace for rubber recycling. Background Technology

[0002] Gas pyrolysis furnaces used for rubber recycling are core equipment that use gas heating to pyrolyze waste rubber, such as tires and seals, in an oxygen-free or low-oxygen environment to extract recyclable resources such as fuel oil, carbon black, and steel wire.

[0003] Existing Chinese patent document CN205653411U discloses an environmentally friendly waste rubber pyrolysis furnace, including a pyrolysis chamber and a combustion chamber. The pyrolysis chamber is fixedly installed on the top of the combustion chamber. A feed inlet is located at the top of the pyrolysis chamber, and a discharge outlet is located on one side of the pyrolysis chamber. An inclined plate is installed inside the cavity of the pyrolysis chamber. A fuel oil outlet at the bottom of one side of the pyrolysis chamber is connected to one end of a fuel oil outlet pipe. The other end of the fuel oil outlet pipe penetrates the side wall of the combustion chamber and extends into the cavity of the combustion chamber. A gas exchange port is located at the top of the other side of the pyrolysis chamber. This environmentally friendly waste rubber pyrolysis furnace... The furnace has a simple structure and is easy to use. It can transport the fuel oil and fuel gas generated during the pyrolysis of waste rubber to the combustion chamber for use as fuel. This not only achieves the purpose of energy saving, but also avoids the generated gas from entering the air and affecting the environment, thus achieving the goal of environmental protection. However, this gas pyrolysis furnace for rubber recycling still has shortcomings: it lacks a raw material pretreatment function. Waste rubber raw materials are directly fed into the pyrolysis chamber from the feed inlet. Dust, mud and other impurities attached to the surface will be mixed into the products during the pyrolysis process, reducing the purity of fuel oil and fuel gas. At the same time, the accumulation of impurities may also affect the heat transfer efficiency of the pyrolysis chamber. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the above-mentioned gas pyrolysis furnace for rubber recycling lacks raw material pretreatment function. Waste rubber raw materials are directly fed into the pyrolysis chamber from the feed port. Dust, mud and other impurities attached to the surface will be mixed into the product during the pyrolysis process, reducing the purity of fuel oil and gas. At the same time, the accumulation of impurities may also affect the heat transfer efficiency of the pyrolysis chamber. Therefore, this utility model provides a gas pyrolysis furnace for rubber recycling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas pyrolysis furnace for rubber recycling, comprising: a gas pyrolysis furnace body, an L-shaped feed box mounted on the top of the gas pyrolysis furnace body, a feed inlet extending through one end of the top surface of the gas pyrolysis furnace body, a feed hopper extending through one end of the top surface of the L-shaped feed box, a spray trough extending through the middle section of the top surface of the L-shaped feed box, a spray plate fixedly embedded inside the spray trough, a spray pipe provided on the bottom surface of the spray plate, several sets of sieve holes evenly distributed on the bottom surface of the L-shaped feed box, and a receiving box slidably connected to the bottom of the L-shaped feed box.

[0006] As a further improvement of this utility model: the vertical section outlet of the L-shaped feed box is connected to the gas pyrolysis furnace body through the feed inlet, and two sets of supporting side plates are symmetrically fixed to one end of the bottom surface of the L-shaped feed box to support the horizontality of the L-shaped feed box.

[0007] As a further embodiment of this utility model: a material feeding drive motor is fixedly connected to one end of the outer side of the L-shaped feeding box, and several sets of material feeding tooth plates are uniformly fixedly connected around the outer side of the output shaft of the material feeding drive motor, so as to uniformly feed the rubber raw material entering from the feeding hopper into the L-shaped feeding box.

[0008] As a further embodiment of this utility model: a discharge drive motor is fixedly connected to the other end of the L-shaped feed box, and several sets of discharge baffles are uniformly fixed around the output shaft of the discharge drive motor so as to uniformly baffle the rubber raw material after spraying and rinsing out of the L-shaped feed box and into the interior of the gas pyrolysis furnace body from the feed inlet.

[0009] As a further embodiment of this utility model: the spray tank and spray plate are arranged between the feeding drive motor and the discharging drive motor, a liquid storage box is fixedly connected to one end of the top surface of the L-shaped feed box, a liquid pump is installed on one side of the liquid storage box, and the output end of the liquid pump is connected to the spray pipe.

[0010] As a further improvement of this utility model: the screen holes are set through the bottom surface of the L-shaped feed box, and there are several sets of them, so that the dust and impurities under the spray washing can pass through the screen holes and fall into the receiving box below. The bottom surface of the bending part inside the L-shaped feed box is fixed with an anti-overflow strip to prevent the spray water from accumulating inside and entering the gas pyrolysis furnace body.

[0011] As a further embodiment of this utility model: the receiving box is slidably inserted between the bottom of the L-shaped feed box and the two sets of supporting side plates. A filter frame is fixedly connected to the middle section inside the receiving box. A filter screen for intercepting impurities and mud is mounted on the top surface of the filter frame. A drain pipe is connected through the bottom of one side of the receiving box to quickly separate solids and liquids falling into the receiving box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves full coverage of raw material pretreatment through the coordinated design of the L-shaped feeding box's feeding, spraying, and discharging structures. The feeding drive motor drives the wear-resistant toothed plate to push the raw material in small amounts and multiple times evenly, avoiding accumulation and blockage while laying the foundation for rinsing. The spraying system covers the raw material in all directions through vertical dense spray holes, and works with the screen holes to quickly remove impurities, effectively removing dust and impurities from the surface of the raw material. This solves the problem of low raw material cleanliness leading to poor purity of pyrolysis products in traditional equipment. The discharging plate, through high-frequency small-amplitude prying and the design of being in contact with soft rubber strips, achieves uniform and quantitative conveying of raw materials, ensuring that the feed rate matches the furnace's processing capacity and avoiding fluctuations in pyrolysis efficiency caused by uneven feeding in traditional equipment. The overall pretreatment process makes the subsequent pyrolysis reaction more complete and significantly improves the purity of the products. 2. In this utility model, solid-liquid separation is achieved by using the drawer-type structure of the receiving box in conjunction with the filter screen. The filtered cleaning liquid can be returned to the storage box through the drain pipe to form a circulation system, which saves water resources and reduces sewage discharge, thus solving the environmental problem of direct sewage discharge in traditional equipment.

The embodiments of this utility model will be described below based on its overall structure.

[0017] Reference Figures 1 to 7 In this embodiment of the present invention, a gas pyrolysis furnace for rubber recycling includes: a gas pyrolysis furnace body 1, an L-shaped feed box 2 mounted on the top of the gas pyrolysis furnace body 1, a feed inlet 3 extending through one end of the top surface of the gas pyrolysis furnace body 1, a feed hopper 5 extending through one end of the top surface of the L-shaped feed box 2, a spray trough 8 extending through the middle section of the top surface of the L-shaped feed box 2, a spray plate 9 fixedly embedded inside the spray trough 8, a spray pipe 12 provided on the bottom surface of the spray plate 9, a plurality of sets of sieve holes 15 evenly opened on the bottom surface of the L-shaped feed box 2, and a receiving box 17 slidably connected to the bottom of the L-shaped feed box 2.

[0018] Reference Figures 1 to 3 The vertical section outlet of the L-shaped feed box 2 is connected to the gas pyrolysis furnace body 1 through the feed inlet 3. Two sets of supporting side plates 4 are symmetrically fixed to one end of the bottom surface of the L-shaped feed box 2 to support the horizontality of the L-shaped feed box 2.

[0019] The above scheme is adopted: the vertical section outlet of the L-shaped feed box 2 and the feed inlet 3 are connected by flange sealing. A high-temperature resistant rubber sealing ring is installed between the flanges to avoid leakage of high-temperature gas in the furnace during the pyrolysis process and to prevent external impurities from entering the furnace body through the gaps. The two sets of support side plates 4 are made of thick-walled stainless steel plates and are fixed to one end of the bottom surface of the L-shaped feed box 2 by welding or bolting. The bottom of the side plate is attached to the top surface of the gas pyrolysis furnace body 1, and the contact surface is covered with anti-slip pads to further enhance the support stability. The height of the support side plates 4 is precisely calculated to ensure that the horizontal section of the L-shaped feed box 2 remains horizontal, to avoid the rubber raw material from being tilted and piled up during the transportation process, to ensure that the subsequent spraying and feeding process is carried out evenly, and to prevent the spraying water from overflowing due to tilting and converging to one end.

[0020] Reference Figure 6 A material feeding drive motor 6 is fixedly connected to one end of the outer side of the L-shaped feed box 2. Several sets of material feeding tooth plates 7 are evenly fixed around the outer side of the output shaft of the material feeding drive motor 6 so as to evenly push the rubber raw material entering from the feed hopper 5 into the L-shaped feed box 2.

[0021] The above-mentioned scheme is designed to achieve uniform distribution of rubber raw materials and avoid material blockage. The material distribution drive motor 6 is a low-speed asynchronous motor, which is fixed to one end of the L-shaped feed box 2 by a motor bracket. The motor output shaft passes through the side wall of the L-shaped feed box 2 and is sealed by a bearing to prevent spray water from seeping into the motor. The material distribution toothed plates 7 are made of wear-resistant alloy steel. Each set of toothed plates ensures that it can displace large pieces of raw materials without causing material jamming due to insufficient spacing. Several sets of material distribution toothed plates 7 are evenly distributed along the circumference of the output shaft. When the motor rotates, the toothed plates can continuously push the raw materials falling from the feed hopper 5 to the middle section of the feed box to avoid the accumulation and blockage of raw materials at the feed inlet. At the same time, the low-speed rotation achieves uniform distribution of small amounts of material multiple times, laying the foundation for the comprehensiveness of subsequent spray rinsing.

[0022] Reference Figure 6 The other end of the L-shaped feed box 2 is fixedly connected to the discharge drive motor 13. Several sets of discharge baffles 14 are evenly fixed around the output shaft of the discharge drive motor 13 so as to uniformly baffle the rubber raw material after spraying and rinsing out of the L-shaped feed box 2 and into the gas pyrolysis furnace body 1 from the feed inlet 3.

[0023] The above-mentioned scheme is key to achieving uniform and quantitative conveying of the raw materials after rinsing. The discharge drive motor 13 is also an adjustable-speed motor, its speed matching the processing capacity of the gas pyrolysis furnace body 1 to ensure a balance between the feed rate and the pyrolysis rate. The motor is connected to the side wall of the L-shaped feed box 2 via sealed bearings to prevent high temperatures and spray water from affecting motor operation. The discharge deflector 14 is made of rigid plastic to avoid sparks from collisions with the stainless steel feed box, meeting the explosion-proof requirements of rubber recycling. The deflector area is larger than the deflector tooth plate 7, and the edge of the deflector... Equipped with soft rubber strips, it can fit tightly against the inner wall of the feed box, ensuring that the raw materials in the box are completely ejected and avoiding residue. The distribution density of the discharge deflector 14 is higher than that of the deflector tooth plate 7. Through high-frequency, small-amplitude deflection, it achieves uniform conveying of raw materials, preventing the raw materials from falling into the feed inlet 3 due to gravity, which would cause uneven feeding in the furnace and affect the pyrolysis efficiency. At the same time, the soft rubber strips can reduce the wear of the deflector plate on the inner wall of the feed box and extend the service life of the equipment. The complete plate of the discharge deflector 14 can also ensure that spray water is not splashed into the interior of the gas pyrolysis furnace body 1 during rotation.

[0024] Reference Figure 4 The spray tank 8 and spray plate 9 are located between the feeding drive motor 6 and the discharge drive motor 13. One end of the top surface of the L-shaped feed box 2 is fixedly connected to the liquid storage box 10. A liquid pump 11 is installed on one side of the liquid storage box 10. The output end of the liquid pump 11 is connected to the spray pipe 12.

[0025] The above-mentioned solution is adopted in the following ways: The core design of the spray system is to achieve efficient rinsing and impurity removal of rubber raw materials. The dimensions of the spray tank 8 are matched with the spray plate 9. The spray plate 9 is made of stainless steel perforated plate and is fixedly embedded in the spray tank 8 with bolts, which ensures structural stability and facilitates subsequent disassembly and cleaning. The volume of the liquid storage box 10 is designed according to the spraying requirements. The top of the liquid storage box 10 is equipped with a liquid inlet and a liquid level observation window, which facilitates the operator to replenish the cleaning fluid in time and monitor the liquid level. The pump 11 is a corrosion-resistant centrifugal pump, and its inlet end is connected to the storage tank. The bottom of the liquid box 10 is open, and the water outlet is connected to the spray pipe 12 through a high-pressure resistant hose. The spray pipe 12 is evenly arranged along the bottom surface of the spray plate 9, and the bottom surface of the pipe is provided with dense spray holes, which are vertically oriented towards the inside of the feed box to ensure that the cleaning liquid can evenly cover the entire raw material conveying area and achieve all-round rinsing. By setting the spray system between the feeding and discharging structures, the raw materials can be evenly distributed by feeding, then thoroughly rinsed by spraying, and finally sent away by the discharging structure, forming a continuous process of feeding, rinsing, and discharging, thereby improving the impurity removal efficiency.

[0026] Reference Figure 6The screen holes 15 are set through the bottom surface of the L-shaped feed box 2, and there are several sets of them, so that the dust and impurities under the spray washing can pass through the screen holes 15 and fall into the receiving box 17 below. The bottom surface of the bending part inside the L-shaped feed box 2 is fixed with an anti-overflow strip 16 to prevent the spray water from accumulating inside and entering the gas pyrolysis furnace body 1.

[0027] The above scheme is adopted: the screen holes 15 are evenly distributed in a matrix on the bottom surface of the horizontal section of the L-shaped feed box 2, which ensures that the sewage and fine impurities generated during rinsing can fall quickly, while preventing the rubber raw material from leaking out of the screen holes. The anti-overflow strip 16 is made of high temperature resistant rubber and is double-fixed to the inside bend of the feed box by bonding and bolts to form a water barrier. It can intercept the water that may flow into the vertical section during the spraying process and prevent the water from entering the feed inlet 3 with the raw material. This avoids the water from instantly vaporizing due to the high temperature in the furnace and causing safety hazards. At the same time, it prevents the water from reacting with the pyrolysis products in the furnace and affecting the recovery quality. In addition, the edges of the screen holes 15 are rounded to prevent sharp edges from scratching the operators or damaging the receiving box 17.

[0028] Reference Figure 7 The receiving box 17 is slidably inserted between the bottom of the L-shaped feed box 2 and the two sets of supporting side plates 4. A filter frame 18 is fixedly connected to the middle section inside the receiving box 17. A filter screen 19 for intercepting impurities and mud is mounted on the top surface of the filter frame 18. A drain pipe 20 is connected through the bottom of one side of the receiving box 17 to quickly separate solids and liquids falling into the receiving box 17.

[0029] The above-mentioned solution is adopted: the receiving box 17 adopts a drawer-type structure made of stainless steel, with slide rails on both sides of the box body, which can slide along the slide grooves on the inner side of the support side plate 4, making it convenient for operators to periodically pull out and clean impurities. A sealing strip is installed between the slide rails and the slide grooves to prevent sewage from leaking from the gaps. The filter frame 18 is a metal frame structure, which is fixed to the middle section of the receiving box 17 by welding. Its height is higher than the drain pipe 20 interface, ensuring that the filtered cleaning liquid can flow smoothly to the drain pipe. The filter screen 19 is made of nylon and can be directly placed on... The filter frame 18 is easy to disassemble, replace and clean, and can effectively intercept impurities and sand falling from the sieve holes 15 to achieve solid-liquid separation. A manual valve is installed on the drain pipe 20, which can be opened by the operator at regular intervals to discharge the filtered cleaning liquid. If recycling is required, the drain pipe can be connected to the storage box 10 to form a spray, filter and recycling cycle system to save water resources. The front end of the receiving box 17 is equipped with a handle and an observation window, which makes it convenient for the operator to judge the accumulation of impurities and the level of cleaning liquid, and to clean and drain the liquid in a timely manner.

[0030] The working principle of this utility model is as follows: When processing rubber recycling, the rubber raw material to be processed is first put into the L-shaped feeding box 2 from the feeding hopper 5. At this time, the material feeding drive motor 6 at one end of the outer side of the L-shaped feeding box 2 is started, and its output shaft drives several sets of material feeding tooth plates 7 to rotate at a constant speed. The wear-resistant alloy steel tooth plates continuously push the concentrated raw material to the middle section of the feeding box. The material is evenly distributed in small amounts and multiple times to avoid the accumulation and blockage of the raw material. At the same time, it lays the foundation for the comprehensiveness of the subsequent spray rinsing. During this process, the two sets of support side plates 4 are supported by the thick-walled stainless steel plate and the friction of the anti-slip pad to ensure that the horizontal section of the L-shaped feeding box 2 remains horizontal and to prevent the raw material from being unevenly distributed due to tilting. After the raw material is pushed to the middle section of the feeding box, the spraying system is started simultaneously. The cleaning liquid in the storage box 10 is drawn by the liquid pump 11 and delivered to the spray pipe 12 on the bottom surface of the spray plate 9 through the high-pressure resistant hose. The dense spray holes spray the cleaning liquid vertically onto the surface of the rubber raw material to achieve all-round rinsing and remove dust and impurities attached to the surface of the raw material. Since the spraying system is located between the feeding and discharging structures, the raw material that is evenly distributed by feeding can fully contact the cleaning liquid, improving the impurity removal effect. The stainless steel perforated plate structure of the spray plate 9 ensures the stability of the spraying and facilitates subsequent disassembly and cleaning. Wastewater and impurities generated during rinsing fall through the matrix-distributed screen holes 15 on the bottom surface of the L-shaped feed box 2 and into the receiving box 17 at the bottom. The rounded edges of the screen holes 15 prevent scratching the equipment or operators. At the same time, the anti-overflow strip 16 at the bend inside the feed box forms a water barrier to intercept water that may flow into the vertical section, preventing it from entering the feed inlet 3 with the raw materials and causing potential hazards due to high-temperature vaporization in the furnace, and also avoiding affecting the quality of the pyrolysis products. When the rinsed rubber raw material is conveyed to the other end of the feed box, the discharge drive motor 13 starts, and its output shaft drives the discharge baffle 14 with a higher distribution density to rotate. The rigid plastic baffle is tightly attached to the inner wall of the box through the soft rubber strip on the edge, completely pulling out the raw material and pushing it to the feed port 3 at a uniform speed. This ensures that the amount of raw material entering the gas pyrolysis furnace body 1 matches the furnace's processing capacity, preventing uneven feeding from affecting the pyrolysis efficiency. At the same time, the soft rubber strip reduces wear on the box, and the complete plate design also avoids a large amount of spray water splashing into the furnace. Throughout the feeding process, the receiving box 17 simultaneously completes solid-liquid separation. After the falling wastewater and impurities enter the drawer-type receiving box, the nylon filter screen 19 intercepts solid impurities. The filtered cleaning liquid is discharged through the drain pipe 20. If recycling is required, the drain pipe can be connected to the storage box 10 to form a closed-loop system. The operator can judge the accumulation of impurities through the observation window at the front of the receiving box and periodically remove and clean it. The cooperation between the slide rail and the sealing strip facilitates operation and prevents wastewater leakage.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
