Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a high-temperature waste gas treatment device for food processing. Background Technology

[0002] During food processing, baking, frying, sterilization and other processes generate a large amount of high-temperature waste gas. The waste gas not only contains impurities such as oil mist, starch dust, and protein particles, but also has a certain amount of residual heat and a high temperature. If this type of waste gas is directly discharged, it will pollute the workshop and the surrounding environment, harm human health, and waste the residual heat seriously. Therefore, it needs to be purified by special equipment before being discharged.

[0003] Existing purification equipment, such as electrostatic precipitators and bag filters, is difficult to adapt to the complex working conditions of food processing exhaust gases and has shortcomings. The filter bags of bag filters are prone to sticking and clumping in high-temperature and oil mist environments, resulting in a significant decrease in filtration efficiency. The electrodes of electrostatic precipitators are easily covered by oil mist, affecting the discharge and impurity removal effect. Moreover, the electrodes need to be disassembled and cleaned during maintenance, which is cumbersome and difficult. At the same time, traditional equipment often lacks an adaptive cleaning structure, making it prone to clogging and resulting in unstable purification effects, which cannot meet the continuous operation requirements of food processing. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a high-temperature waste gas treatment device for food processing to solve the problems mentioned in the background section. This invention features a novel structure. By incorporating an adaptive cleaning linkage structure and a heat exchanger, it effectively improves the problems of filter bag adhesion and electrode susceptibility to oil mist coverage in traditional equipment. The heat exchanger first cools the high-temperature waste gas, preventing oil mist from adhering due to increased viscosity at high temperatures. Combined with a felt filter screen, it enhances filtration stability. Utilizing the kinetic energy of the waste gas to drive an energy storage mechanism, and combined with a pressure-triggered unlocking mechanism, it achieves automatic filter cleaning without manual disassembly and cleaning, significantly reducing maintenance difficulty. This invention overcomes the shortcomings of traditional equipment, such as the lack of an adaptive cleaning structure, susceptibility to clogging, and unstable purification effects, meeting the continuous operation requirements of food processing while reducing waste heat and environmental pollutant emissions.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Please refer to Figures 1 to 8This invention provides a technical solution: a high-temperature waste gas treatment device for food processing, including a mounting plate 1, a heat exchanger 2 mounted on the upper side of the mounting plate 1, a waste gas treatment box 3 mounted on the upper side of the mounting plate 1, a connecting pipe 4 fixedly connected to the output end of the heat exchanger 2, an installation cavity 5 opened inside the waste gas treatment box 3, two support plates 6 fixedly connected to the lower side of the inner wall of the installation cavity 5, a driving mechanism 7 arranged inside the waste gas treatment box 3, and a felt filter plate 8 fixedly connected to the inner wall of the waste gas treatment box 3. A driven rod 9 is rotatably fitted to one side of the inner wall of the exhaust gas treatment box 3. The driven rod 9 passes through the center of the felt filter plate 8 and is fixedly connected to a scraper 10 that cooperates with one side of the felt filter plate 8. The exhaust gas treatment box 3 is equipped with a power storage mechanism 11 that cooperates with the drive mechanism 7. Two mounting rods 12 are fixedly connected to the upper side of the mounting plate 1. A sliding groove 13 is opened on the upper side of the inner wall of the exhaust gas treatment box 3. An unlocking mechanism 14 is installed inside the sliding groove 13. An exhaust pipe 15 is fixedly connected to one side of the exhaust gas treatment box 3. One end of the connecting pipe 4 is fixedly connected to one side of the exhaust gas treatment box 3, and the upper ends of the two mounting rods 12 are fixedly connected to the lower side of the exhaust gas treatment box 3. High-temperature exhaust gas enters through the inlet pipe 23 of heat exchanger 2. Heat exchanger 2 achieves heat exchange through the water flow of inlet pipe 21 and drain pipe 22, cooling the exhaust gas and preventing high temperature damage to subsequent purification components. The cooled exhaust gas enters the mounting cavity 5 of exhaust gas treatment box 3 through connecting pipe 4. Mounting plate 1 provides stable support to exhaust gas treatment box 3 through mounting rod 12. Felt filter plate 8 intercepts residual oil mist and fine dust in the exhaust gas. Scraper 10 on driven rod 9 is in standby mode. Exhaust pipe 15 is the discharge channel for purified gas. This section of the structure realizes the cooling pretreatment and preliminary filtration of exhaust gas, laying the foundation for the subsequent automatic cleaning process and ensuring that the equipment operates within a safe temperature range.

[0030] In this embodiment, the drive mechanism 7 includes a drive shaft 71 rotatably mounted on a support plate 6 on the left side. One end of the drive shaft 71 is fixedly connected to an impeller 72, and the other end of the drive shaft 71 is slidably fitted with a sliding sleeve 73 via a spline. One end of the sliding sleeve 73 is fixedly connected to a drive ratchet chuck 74, and a first spring 75 is sleeved on the drive shaft 71. The two ends of the first spring 75 abut against the drive ratchet chuck 74 and the boss on the drive shaft 71, respectively. When the exhaust gas flows into the installation cavity 5, it impacts the impeller 72 of the drive mechanism 7, causing the drive shaft 71 to rotate on the left support plate 6. The drive shaft 71 drives the sliding sleeve 73 to rotate synchronously through the spline. The first spring 75 continuously applies elastic force to the sliding sleeve 73, keeping the drive ratchet chuck 74 at the end of the sliding sleeve 73 engaged with the power storage mechanism 11. The drive mechanism 7 does not require an additional power source and relies on the kinetic energy of the exhaust gas itself to complete the operation, saving equipment energy consumption. At the same time, the spline structure ensures that the sliding sleeve 73 can slide along the axial direction of the drive shaft 71, providing structural support for subsequent clutch actions and realizing stable power transmission and flexible switching.

[0031] In this embodiment, the power storage mechanism 11 includes a ratchet 111 fixedly connected to the driven rod 9. A spring 112 is fixedly connected to one side of the inner wall of the exhaust gas treatment box 3, and the movable end of the spring 112 is fixedly connected to one side of the driven rod 9. A rotating rod 113 is rotatably engaged with one side of the inner wall of the exhaust gas treatment box 3, and a pawl 114 is rotatably engaged with one end of the rotating rod 113. A second spring 115 is fixedly connected to one side of the inner wall of the exhaust gas treatment box 3. A driven ratchet chuck 116 is fixedly connected to one end of the driven rod 9 near the drive ratchet chuck 74. One end of the second spring 115 is fixedly connected to one side of the pawl 114. The pawl 114 is unidirectionally engaged with the ratchet 111. The drive ratchet chuck 74 and the driven ratchet chuck 116 are connected by trapezoidal helical teeth. When the drive ratchet chuck 74 rotates, the driven ratchet chuck 116 rotates through the trapezoidal helical teeth, which in turn drives the driven rod 9 to rotate. During the rotation of the driven rod 9, the spring 112 is wound up to complete the energy storage. At the same time, the second spring 115 on the inner wall of the exhaust gas treatment box 3 pushes the pawl 114 to engage with the ratchet 111 in one direction, restricting the driven rod 9 from rotating in the opposite direction, so that the energy storage state of the spring 112 can be maintained. This energy storage mechanism 11 stores energy through a mechanical self-locking structure, replacing the traditional electric energy storage component, improving the stability of the equipment under high temperature and dusty conditions. The one-way engagement design ensures that there is no energy loss during the energy storage process, and reserves sufficient power for subsequent cleaning operations.

[0032] In this embodiment, the unlocking mechanism 14 includes two piston plates 141 that slide together on the inner wall of the slide groove 13. A connecting rod 142 is fixedly connected between the two piston plates 141. A third spring 143 is fixedly connected to one side of the inner wall of the slide groove 13. One end of the third spring 143 is fixedly connected to one side of the right piston plate 141. A connecting block 144 is fixedly connected to the lower side of the right piston plate 141. A trapezoidal pressing block 145 is fixedly connected to one side of the connecting block 144. A trigger rod 149 is fixedly connected to one side of the pawl 114. The inclined end of the trapezoidal pressing block 145 abuts against one side of the trigger rod 149. The unlocking mechanism 14 also includes a drive frame 146 fixedly connected to the lower side of the piston plate 141 on the left side, a swing frame 147 rotatably fitted on one side of the inner wall of the exhaust gas treatment box 3, a strip groove 148 is provided at the upper end of the swing frame 147, the lower end of the drive frame 146 is slidably fitted on the inner wall of the strip groove 148, and the sliding sleeve 73 is movably fitted on the inner wall of the swing frame 147. When the felt filter plate 8 becomes clogged, causing the air pressure in the installation cavity 5 to rise, high-pressure gas enters the slide groove 13, pushing the two piston plates 141 to slide against the elastic force of the third spring 143. The connecting rod 142 ensures that the piston plates 141 move synchronously. The right piston plate 141 drives the trapezoidal extrusion block 145 to extrude the trigger rod 149 through the connecting block 144, unlocking the engagement between the pawl 114 and the ratchet 111. The left piston plate 141 slides in the strip groove 148 of the swing frame 147 through the drive frame 146, pushing the swing frame 147 to rotate, causing the sliding sleeve 73 to slide along the drive shaft 71, so that the drive ratchet chuck 74 separates from the driven ratchet chuck 116. This unlocking mechanism is automatically triggered by air pressure changes, without manual intervention, and simultaneously completes the two actions of "unlocking and accumulating power + cutting off power", ensuring the precise start of the cleaning process.

[0033] In this embodiment, an inclined guide plate 16 is fixedly connected to the lower side of the inner wall of the exhaust gas treatment box 3 near the connecting pipe 4. A first collection groove 17 is formed on the lower side of the inner wall of the exhaust gas treatment box 3, which cooperates with the inclined guide plate 16. A first cleaning door 18 is rotatably connected to the lower side of the exhaust gas treatment box 3, which cooperates with the first collection groove 17. A second collection groove 19 is formed on the lower side of the inner wall of the exhaust gas treatment box 3, which cooperates with the felt filter plate 8. A second cleaning door 20 is rotatably connected to the lower side of the exhaust gas treatment box 3, which cooperates with the second collection groove 19. A water inlet pipe 21 is fixedly connected to the upper side of one end of the heat exchanger 2, a drain pipe 22 is fixedly connected to the lower side of one end of the heat exchanger 2, and an air inlet pipe 23 is fixedly connected to the upper side of the heat exchanger 2. After the exhaust gas enters the installation chamber 5, it first impacts the inclined guide plate 16. Oil mist and large particulate impurities are blocked by inertia and slide down the inclined guide plate 16 into the first collection tank 17 for collection, reducing the load on subsequent filter components. The fine impurities intercepted by the felt filter plate 8 fall into the second collection tank 19 after being cleaned by the scraper 10. Operators can regularly clean the impurities in the collection tank by rotating the first cleaning door 18 and the second cleaning door 20 to avoid secondary accumulation of impurities. This structure realizes the graded collection and convenient cleaning of impurities. The guiding design of the inclined guide plate 16 improves the collection efficiency of large particulate impurities, and the detachable cleaning door reduces the difficulty of equipment maintenance and ensures long-term stable operation of the equipment.

[0034] When the device is in use, the high-temperature exhaust gas enters through the inlet pipe 23 of the heat exchanger 2. After being cooled by the heat exchanger 2, it is sent to the installation cavity 5 of the exhaust gas treatment box 3 through the connecting pipe 4. The exhaust gas first impacts the inclined guide plate 16, and large particles of impurities and oil mist are intercepted and fall into the first collection tank 17. The remaining exhaust gas drives the impeller 72 to rotate, and the drive shaft 71 drives the drive ratchet chuck 74 to rotate through the sliding sleeve 73, which in turn drives the driven ratchet chuck 116 to rotate, so that the driven rod 9 winds up the spring 112 to store power, and the pawl 114 engages with the ratchet 111 to lock the stored power state.

[0035] When the felt filter plate 8 becomes clogged, causing the air pressure inside the cavity to rise, the high-pressure gas enters the slide groove 13 and pushes the piston plate 141 to slide, simultaneously completing two actions: first, the trapezoidal extrusion block 145 extrudes the trigger rod 149, unlocking the engagement between the pawl 114 and the ratchet 111; second, the drive frame 146 pushes the swing frame 147 to rotate, causing the drive ratchet chuck 74 to separate from the driven ratchet chuck 116. Then, the spring 112 releases its elasticity, driving the driven rod 9 and the scraper 10 to rotate, cleaning the impurities on the surface of the felt filter plate 8. The impurities fall into the second collection tank 19, and the purified gas is discharged through the exhaust pipe 15. Operators can periodically clean the impurities in the collection tank through the cleaning door.

[0036] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
