Description

Technical Field

[0001] This utility model relates to the technical field of waste gas purification devices, and in particular to a high-efficiency collection and treatment device for waste gas from the vulcanization process of a conveyor belt. Background Technology

[0002] As a key component in material transportation, conveyor belts must undergo vulcanization during their production to obtain the required physical and mechanical properties. However, the vulcanization process, under high temperature and pressure, causes complex chemical reactions in the rubber and various compounding agents, inevitably generating industrial waste gases containing various harmful substances such as sulfides, carbon monoxide, dust, and volatile organic compounds. To meet increasingly stringent environmental regulations and protect the health of production workers, effective collection and purification of these waste gases is essential.

[0003] Currently, catalytic oxidation is widely used for treating this type of waste gas due to its high purification efficiency and wide applicability. This method typically involves heating the waste gas to a certain temperature and then passing it through a catalyst bed, where harmful components are oxidized and decomposed into harmless substances such as carbon dioxide and water. During this process, to protect the catalyst's activity and extend its lifespan, a filtration device is usually installed before the waste gas enters the catalytic reaction zone to remove particulate matter such as dust and colloids.

[0004] However, existing waste gas treatment devices reveal a core problem of low overall operating efficiency in practical applications. On the one hand, catalytic oxidation is an exothermic process that generates considerable heat energy, but existing equipment typically releases this heat, along with the purified exhaust gas, directly into the atmosphere, resulting in significant energy waste. Simultaneously, the vulcanizing machine itself consumes a large amount of electricity to heat fresh air to maintain the process temperature, undoubtedly increasing production costs for enterprises. On the other hand, the filter plates in the pre-filter device become clogged over time, requiring regular cleaning or replacement. Traditional equipment typically uses multiple fixing methods, such as bolt fastening, for filter plates, making disassembly complex, requiring specialized tools and consuming considerable time. This reduces the ease of maintenance and production continuity, significantly diminishing the overall "efficiency" of the device.

[0005] Therefore, this utility model proposes an efficient collection and treatment device for waste gas from the vulcanization process of conveyor belts to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a high-efficiency collection and treatment device for waste gas from the vulcanization process of conveyor belts. It aims to improve the existing technology where the heat energy generated by the purification reaction is directly wasted, resulting in high overall energy consumption, and the filter components are complex in structure, cumbersome to replace and disassemble, and inconvenient to maintain.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency collection and treatment device for waste gas from the vulcanization process of a conveyor belt includes a collection box, an inlet pipe, an exhaust pipe, a filtration mechanism, and a purification mechanism.

[0008] The purification mechanism includes a hood and a heat exchange tank. The heat exchange tank is located inside the hood and has an air inlet pipe for introducing fresh air and a return pipe for discharging preheated air. This integrated structure allows the heat generated during exhaust gas purification to be efficiently recovered.

[0009] The filtration mechanism includes a filter plate, an L-shaped support plate, an anti-slip block, a connecting rod, and a sliding block. The inner wall of the collection box has a T-shaped groove for the L-shaped support plate to slide into, and the L-shaped support plate supports the filter plate. The anti-slip block is mounted on the L-shaped support plate and is connected to the sliding block, which is slidably mounted inside the L-shaped support plate, via the connecting rod. The sliding block and the inner wall of the T-shaped groove are engaged or disengaged, enabling quick assembly and disassembly of the filter plate.

[0010] Preferably, a heating device is installed inside the shroud of the purification mechanism, and multiple air inlets are provided on the shroud wall for the exhaust gas to enter. In one specific embodiment, the heating device includes a heating tube, and the inner wall of the shroud is coated with a catalyst.

[0011] Preferably, the efficient collection and treatment device for waste gas from the conveyor belt vulcanization process also includes a baffle plate for controlling the opening and closing of the waste gas inlet, and an electric telescopic rod for driving the movement of the baffle plate.

[0012] Preferably, the telescopic end of the electric telescopic pole is fixedly connected to the barrier plate via a connecting block.

[0013] Preferably, the bottom of the collection box is provided with a flip-open base plate to provide a convenient operating channel for the maintenance of the filtration mechanism.

[0014] Preferably, an L-shaped folding plate is also fixedly connected to the bottom of the collection box to enhance the overall structural strength and support stability of the collection box.

[0015] Preferably, the inner wall of the T-slot is slidably connected to the sliding block to achieve reliable locking of the L-shaped tray.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by setting up a purification mechanism that integrates a catalytic reaction chamber and a heat exchange chamber, the reaction heat generated during the purification of waste gas is used to preheat the fresh air entering the vulcanizing machine. This solves the problem that existing waste gas treatment devices usually directly discharge the heat energy generated by the purification reaction without recycling, resulting in high overall production energy consumption. This achieves the technical effect of energy recycling and significantly reducing energy consumption in the production process.

[0017] 2. In this utility model, by setting a quick-release structure consisting of an L-shaped support plate, a T-shaped groove, and anti-slip blocks and linkage blocks that cooperate with it, the problem of complex structure of filter components, cumbersome disassembly and assembly during replacement, time-consuming and labor-intensive, and poor maintenance convenience in the prior art is solved. It achieves the technical effect of realizing quick and tool-free disassembly and installation of filter plates, greatly simplifying the maintenance process, and improving the convenience of equipment use and work efficiency.

[0020] 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.

[0021] Please refer to Figures 1 to 6 This utility model provides a high-efficiency collection and treatment device for waste gas from the vulcanization process of conveyor belts. It aims to solve the problems of high overall energy consumption caused by the direct waste of heat energy generated by the purification reaction in existing waste gas treatment devices for vulcanization of conveyor belts, as well as the cumbersome replacement and disassembly of filter components and inconvenient maintenance.

[0022] like Figure 1 and Figure 2 As shown, the efficient collection and treatment device for waste gas from the conveyor belt vulcanization process includes a collection box 1 as an integral installation frame, an inlet pipe 2 and an exhaust pipe 8 both fixed to the collection box 1. Specifically, the inlet pipe 2 is located on the side wall of the collection box 1 to introduce the vulcanization waste gas, and the exhaust pipe 8 is located on the top of the collection box 1 to discharge the purified gas. Inside the collection box 1, a filter mechanism 7 and a purification mechanism 6 are arranged sequentially on the gas flow channel.

[0023] The purification mechanism 6 is the core of realizing exhaust gas purification and heat recovery. It includes a shroud 603 and a heat exchange tank 605. The heat exchange tank 605 is located inside the shroud 603. This close arrangement allows the heat generated by the shroud 603 during the exothermic reaction to be efficiently transferred to the heat exchange tank 605. The heat exchange tank 605 has an air inlet pipe 607 for introducing fresh air and a return pipe 606 for discharging preheated air. The air inlet pipe 607 and the return pipe 606 are respectively connected to the two ends of the heat exchange tank 605 to form a preheating channel for fresh air.

[0024] The filtration mechanism 7 is used to pre-treat exhaust gas and facilitate convenient maintenance. It includes a filter plate 701, an L-shaped support plate 703, an anti-slip block 704, a connecting rod 705, and a sliding block 706. A T-shaped groove 702 is integrally formed or fixedly connected to the inner wall of the collection box 1. The T-shaped groove 702 serves as a guide rail for the L-shaped support plate 703 to slide in or out. The L-shaped support plate 703 is used to horizontally support the replaceable filter plate 701. The anti-slip block 704 is located at the outer end of the L-shaped support plate 703 for easy pressing by the operator. The sliding block 706 is slidably embedded in the interior of the T-shaped groove 702. The L-shaped support plate 703 is connected to the sliding block 706 via the connecting rod 705. When the anti-slip block 704 is pressed, it can drive the sliding block 706 to move. One end of the sliding block 706 is used to slide against the inner wall of the T-shaped groove 702, thereby enabling the L-shaped support plate 703 to quickly lock or unlock the filter plate 701.

[0025] To achieve the above-mentioned functions of exhaust gas purification and heat recovery, the core structure of this embodiment lies in the ingenious internal structure of the purification mechanism 6 and its coordinated relationship with the external air path. At the same time, the device is also equipped with an automated inlet control mechanism and a convenient maintenance structure.

[0026] Please refer to the following carefully. Figure 3 and Figure 4 The core structure of purification mechanism 6 will be described in detail below: The shroud 603 of the purification mechanism 6 has multiple air inlets 604 evenly distributed on its cylinder wall. The pre-filtered exhaust gas enters the internal reaction chamber of the shroud 603 through these air inlets 604. The inner wall of the shroud 603 is coated with a catalyst for catalyzing the oxidation reaction of harmful gases such as carbon monoxide. At the center of the shroud 603, a heating device 601 is provided. The heating device 601 includes at least one heating tube 602. When the heating tube 602 is energized, it generates heat to provide the necessary high-temperature environment for the catalytic reaction.

[0027] Meanwhile, the heat exchange tank 605 is set as an independent cavity inside the cover 603, with a certain space between the two to ensure the heat conduction of the hot air. The fresh air from outside before entering the vulcanizing machine is pumped into the internal space of the heat exchange tank 605 through the air inlet pipe 607, where it circulates and fully absorbs the reaction heat conducted from the cover 603. The preheated high-temperature clean air is then transported to the vulcanizing machine through the return pipe 606. This heat exchange structure efficiently recovers and utilizes the heat energy generated during the waste gas treatment process, significantly reducing production energy consumption.

[0028] For the auxiliary mechanism of the device, a baffle plate 5 that can move up and down is provided at the exhaust gas inlet of the collection box 1 to control the opening and closing of the exhaust gas passage. The baffle plate 5 is driven by an electric telescopic rod 3. The telescopic end of the electric telescopic rod 3 is fixedly connected to the baffle plate 5 through a connecting block 4, thereby realizing the automatic control of the exhaust gas entry. At the bottom of the collection box 1, there is a flip-open bottom plate 9 to provide an open operating channel when the filter mechanism 7 needs to be maintained or replaced. In order to enhance the overall structural strength and stability of the bottom of the collection box 1, an L-shaped folding plate 10 is also fixedly connected to its bottom.

[0029] As a preferred embodiment, please refer to Figure 5 and Figure 6To improve the reliability and stability of locking the L-shaped tray 703, the inner wall of the T-shaped groove 702 is provided with a locking part that cooperates with the sliding block 706. The locking part can be a groove or a limiting protrusion. When the sliding block 706 moves to the locking position under the drive of the connecting rod 705, its end is just locked into the groove or abuts against the limiting protrusion, thereby forming a stable mechanical lock and effectively preventing the L-shaped tray 703 from accidentally loosening or slipping out during long-term operation or vibration of the equipment.

[0030] As another preferred embodiment, please refer to Figure 3 To ensure efficient catalytic oxidation of harmful substances such as carbon monoxide in sulfidation waste gas, a heating device 601 is installed at the center of the hood 603 of the purification mechanism 6. Specifically, it can be multiple quartz heating tubes 602 arranged in an array or resistance wire heating tubes 602. At the same time, a catalyst is uniformly coated on the inner wall of the hood 603. It is preferably a catalyst material with rare earth composite oxides or precious metals as active components to ensure high catalytic activity and long service life at a specific temperature.

[0031] As another preferred embodiment, please refer to Figure 1 and Figure 2 In order to achieve automated control of the exhaust gas inlet and synchronize with the production cycle of the vulcanizing machine, the model of the electric telescopic rod 3 installed outside the collection box 1 can be selected according to the actual working conditions. It is fixedly connected to the upper end of the baffle plate 5 through a sturdy connecting block 4. The connecting block 4 can be designed as a component with a buffer structure to absorb the impact during the opening and closing of the baffle plate 5 and ensure smooth operation.

[0032] As another preferred embodiment, please refer to Figure 1 To further facilitate the maintenance and replacement of the filter mechanism 7 while ensuring the overall structural strength of the equipment, the bottom plate 9 of the collection box 1 is rotatably connected to the collection box 1 via a hinge and fixed with quick-locking bolts. The L-shaped folding plate 10 welded to the outside of the bottom of the collection box 1 not only serves as the support foot of the equipment but also acts as a reinforcing rib for the bottom corner of the collection box 1, thereby improving the rigidity of the overall frame.

[0033] Working principle: When the vulcanizing machine starts working, the external control system activates the electric telescopic rod 3. The telescopic end of the electric telescopic rod 3 drives the baffle plate 5 to move upward through the connecting block 4, opening the exhaust gas inlet of the collection box 1. The high-temperature exhaust gas generated during the vulcanization process is then sucked into the interior of the collection box 1 from the air inlet pipe 2. The exhaust gas first passes through the filter plate 701 in the filter mechanism 7. During this process, large particles such as dust and colloids in the exhaust gas are intercepted, and some harmful gases are initially adsorbed.

[0034] The exhaust gas, after initial filtration, continues to rise and enters the internal reaction chamber through multiple air inlets 604 on the wall of the hood 603 in the purification mechanism 6. At this time, the heating device 601, i.e., the heating tube 602, located inside the hood 603, is energized and heats up, rapidly raising the temperature inside the reaction chamber to the activation temperature required for the catalytic reaction. Under the combined action of the high temperature and the catalyst coated on the inner wall of the hood 603, harmful components such as carbon monoxide in the exhaust gas are efficiently oxidized into harmless substances such as carbon dioxide. This chemical reaction process releases a large amount of heat energy.

[0035] While the purification reaction is underway, fresh outside air enters the heat exchange tank 605 inside the shroud 603 through the air inlet pipe 607 under the action of the fan. Due to the tight fit between the heat exchange tank 605 and the shroud 603, the heat energy generated by the purification reaction is efficiently transferred to the air inside the heat exchange tank 605, preheating it. The preheated high-temperature clean air is then transported back to the air inlet of the vulcanizing machine through the return pipe 606 for use in the vulcanizing process, thus realizing the recovery and utilization of energy. The qualified gas after purification is discharged from the exhaust pipe 8 at the top of the collection box 1.

[0036] When the filter plate 701 needs to be replaced, the maintenance personnel first flip up the base plate 9 fixed by bolts, and then press the anti-sliding block 704 on the L-shaped support plate 703 with their hands. The anti-sliding block 704 moves the sliding block 706 inside it through the connecting rod 705, so that the sliding block 706 is separated from the locking part of the inner wall of the T-shaped groove 702 and the locking state is released. At this time, the L-shaped support plate 703 together with the filter plate 701 supported on it can be easily pulled out from the T-shaped groove 702 for replacement. The whole process does not require complicated tools and is convenient and efficient.
