Description

Waste gas filtration device for food waste treatment Technical Field

[0001] This utility model belongs to the field of waste gas filtration and treatment technology, specifically relating to a waste gas filtration device for treating kitchen waste. Background Technology

[0002] In the process of food waste treatment, after the food waste is separated into oil and water and crushed, the remaining waste residue enters the fermentation tank for fermentation treatment, so that the food waste undergoes further biodegradation. However, during the high-temperature fermentation process, the food waste will produce foul-smelling gases. If these gases are directly emitted, they will pollute the surrounding environment. Therefore, they are filtered.

[0003] Existing waste gas filtration typically uses activated carbon for adsorption because it is inexpensive and readily available. However, it needs to be replaced regularly during use, and the filter device needs to be cleaned and the filter material replaced manually on a regular basis. Otherwise, the filter element will become clogged or its efficiency will decrease. This not only increases labor costs and maintenance workload, but also affects the normal operation of the device and causes inconvenience to the operators. Summary of the Invention

[0004] The purpose of this invention is to provide a waste gas filtration device for food waste treatment, which can automatically clean the filter element, keep the filtration structure in a high-efficiency state, ensure continuous and effective purification of waste gas, reduce air pollution, reduce human intervention, and lower maintenance costs.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A waste gas filtration device for food waste treatment includes a food processing chamber and a filter chamber. The filter chamber is connected to the top of the food processing chamber. A coarse filter element and a fine filter element are installed inside the filter chamber, with the fine filter element located on top of the coarse filter element. An automatic cleaning mechanism is installed inside the filter chamber. The automatic cleaning mechanism includes a structural frame, a cleaning plate, a connecting plate, a threaded rod, a forward and reverse motor, a limit rod, and a movable plate. The structural frame is installed on the front side of the filter chamber. The cleaning plate is respectively located at the top and bottom of the coarse and fine filter elements. One end of the connecting plate extends through the filter chamber and beyond it. Inside the structural frame, the connecting plate is fixedly connected to the end of the cleaning plate and located inside the structural frame. One end of the threaded rod is connected to one side of the inner wall of the structural frame via a bearing, and the other end of the threaded rod extends to the outside of the structural frame. The forward and reverse motors are fixedly installed on one side of the structural frame, and the output end of the forward and reverse motors is fixedly connected to one end of the threaded rod. The limiting rod is fixedly connected inside the structural frame. The movable plate is fixedly connected to the front side of the connecting plate and located inside the structural frame. The movable plate is threadedly connected to the surface of the threaded rod, and the movable plate is slidably connected to the surface of the limiting rod.

[0007] Preferably, a limiting groove is provided on the rear side of the inner wall of the filter box, and a slider is fixedly connected to the rear end of each cleaning plate, and the slider is slidably connected to the inside of the limiting groove.

[0008] Preferably, a sludge storage tank is installed on one side of the filter box, and the sludge storage tank is connected to the filter box.

[0009] Preferably, a flow guide plate is fixedly connected to the inner wall of the filter box, the flow guide plate is installed at a 30-degree angle, and the bottom end of the flow guide plate extends into the interior of the sludge storage box.

[0010] Preferably, the front side of the sludge storage tank is connected to a drain pipe, and a plug is installed inside the drain pipe. The plug is made of an elastic material.

[0011] Preferably, an observation window is provided on one side of the sludge storage tank, and a scale line is provided on one side of the observation window.

[0012] Preferably, the front side of the filter box is provided with a horizontal groove, and the cleaning plates are slidably connected to the inside of the horizontal groove.

[0013] The technical effects achieved by this utility model are as follows:

[0014] In this invention, when exhaust gas is discharged from the food processing box, it passes through the coarse filter and the fine filter in sequence. The harmful substances in the exhaust gas are filtered and adsorbed by these filters. However, after prolonged use, some dirt accumulates on the surfaces of the coarse and fine filters. To address this, a forward and reverse motor is activated. The motor drives a threaded rod to rotate, which in turn moves a threaded movable plate smoothly with the assistance of a limit rod. As the movable plate moves, it also moves the connecting plate and the cleaning plate parallel to each other. Simultaneously, the cleaning plate automatically cleans the dirt adsorbed on the surfaces of the coarse and fine filters, preventing the accumulation of dirt and grease that would reduce filtration efficiency. This ensures continuous and effective purification of the exhaust gas and reduces air pollution.

[0015] In this invention, after the dirt is cleaned up, it slides down and falls onto the inclined guide trough plate. At the same time, the dirt slides down along the guide trough plate and falls into the inside of the dirt storage tank for collection. This avoids the dirt from scattering and avoids omissions during manual cleaning, thus improving the comprehensiveness and efficiency of dirt collection. Attached Figure Description

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] As shown in Figures 1-4, the exhaust gas filtration device for food waste treatment includes a food processing box 1 and a filter box 2. The filter box 2 is connected to the top of the food processing box 1. A coarse filter element 201 and a fine filter element 202 are installed inside the filter box 2. The fine filter element 202 is located on top of the coarse filter element 201. An automatic cleaning mechanism is installed inside the filter box 2. The automatic cleaning mechanism includes a structural frame 203, a cleaning plate 204, a connecting plate 205, a threaded rod 206, a forward / reverse motor 207, a limiting rod 208, and a movable plate 209. The structural frame 203 is installed on the front side of the filter box 2. The cleaning plate 206... 04 are respectively installed at the top and bottom of the coarse filter element 201 and the fine filter element 202. A connecting plate 205 and a cleaning plate 204 are respectively installed at the top and bottom of the coarse filter element 201 and the fine filter element 202. One end of the cleaning plate 204 penetrates into the filter box 2 and extends into the interior of the structural frame 203. The connecting plate 205 is fixedly connected to the end of the cleaning plate 204 and located inside the structural frame 203. One end of the threaded rod 206 is connected to one side of the inner wall of the structural frame 203 via a bearing, and the other end of the threaded rod 206 penetrates to the outside of the structural frame 203. A forward / reverse motor 207 is fixedly installed on one side of the structural frame 203. The output end of the forward / reverse motor 207 is connected to one end of the threaded rod 206. The filter is fixedly connected, with the limiting rod 208 fixedly connected inside the structural frame 203. The movable plate 209 is fixedly connected to the front side of the connecting plate 205 and located inside the structural frame 203. The movable plate 209 is threadedly connected to the surface of the threaded rod 206 and slidably connected to the surface of the limiting rod 208. With the cooperation of the automatic cleaning mechanism, the dirt adsorbed on the surfaces of the coarse filter element 201 and the fine filter element 202 can be automatically cleaned, reducing the workload of manual cleaning and ensuring that the filtration device is always in optimal working condition, thus enhancing filtration efficiency. Regular cleaning of the coarse filter element is also possible. The core 201 and fine filter 202 can prevent excessive dirt buildup in the coarse filter 201 and fine filter 202, thus extending their service life and reducing the cost of frequent filter replacement. Both the coarse filter 201 and fine filter 202 are made of polytetrafluoroethylene, which has excellent corrosion resistance and anti-adhesion properties, making them suitable for filtering different exhaust gases. Their surfaces are relatively smooth, and they can be cleaned to restore high filtration performance. They also have strong reusability, reducing maintenance costs. The threaded rod 206 and the movable plate 209 are both made of stainless steel, which has good corrosion resistance and rust prevention properties.

[0024] As shown in Figures 2 and 4, a limiting groove 301 is provided on the rear side of the inner wall of the filter box 2. The rear end of the cleaning plate 204 is fixedly connected to a slider 302. The slider 302 is slidably connected inside the limiting groove 301. When the cleaning plate 204 moves and cleans the coarse filter element 201 and the fine filter element 202, the cleaning plate 204 can drive the slider 302 to slide inside the limiting groove 301, ensuring that the cleaning plate 204 maintains a fixed trajectory and position during the sliding process, avoiding the cleaning plate 204 from deviating, and ensuring the accuracy and efficiency of the cleaning process.

[0025] As shown in Figures 2 and 4, a sludge storage tank 401 is installed on one side of the filter box 2. The sludge storage tank 401 is connected to the filter box 2. A guide plate 402 is fixedly connected to the inner wall of the filter box 2. The guide plate 402 is installed at a 30-degree angle. The bottom end of the guide plate 402 extends into the interior of the sludge storage tank 401. After the sludge is unloaded, it will fall onto the guide plate 402 and slide down automatically along the tilt direction of the guide plate 402 to be collected inside the sludge storage tank 401, preventing the sludge from scattering everywhere. The working environment of the entire filtration system is more hygienic.

[0026] As shown in Figures 2 and 4, a drain pipe 403 is connected to the front of the sludge storage tank 401. A plug made of elastic material is installed inside the drain pipe 403. When the amount of sludge in the sludge storage tank 401 reaches a certain level, the sludge collected inside the sludge storage tank 401 can be drained through the drain pipe 403. The elastic plug can effectively seal the opening of the drain pipe 403, preventing the sludge from accumulating in the sludge storage tank 401 to a certain extent and then overflowing due to excessive pressure or other factors, thus ensuring the closed nature of the sewage system and avoiding environmental pollution.

[0027] As shown in Figures 2 and 4, an observation window 5 is provided on one side of the sludge storage tank 401, and a scale line is provided on one side of the observation window 5. The observation window 5 allows the operator to easily view the level or accumulation of sludge inside the sludge storage tank 401 and understand the status of sludge in real time. The scale line provides the operator with a visual reference standard and can accurately measure the height of sludge inside the sludge storage tank 401. Through these scales, the operator can determine when to start the sludge discharge process to ensure timely cleaning of sludge and avoid overloading.

[0028] As shown in Figure 4, a transverse groove 6 is provided on the front side of the filter box 2. The cleaning plates 204 are slidably connected to the inside of the transverse groove 6. When the connecting plate 205 moves the cleaning plates 204, the cleaning plates 204 can slide inside the transverse groove 6, so that the cleaning plates 204 have sufficient space to move. This allows them to flexibly clean the coarse filter element 201 and the fine filter element 202, preventing insufficient space for the cleaning plates 204 to affect their cleaning of the coarse filter element 201 and the fine filter element 202.

[0029] The working principle of this utility model is as follows: When exhaust gas is discharged from inside the food processing box 1, the exhaust gas passes through the coarse filter element 201 and the fine filter element 202 in sequence. Harmful substances in the exhaust gas are filtered and adsorbed by the coarse filter element 201 and the fine filter element 202. However, after prolonged use, some dirt will accumulate on the surface of the coarse filter element 201 and the fine filter element 202. Therefore, the forward and reverse motor 207 can be activated. The operation of the forward and reverse motor 207 will drive the threaded rod 206 to rotate. The movable plate 209, connected by threads, moves smoothly with the assistance of the limiting rod 208. As the movable plate 209 moves, it can drive the connecting plate 205 and the cleaning plate 204 to move in parallel. While the cleaning plate 204 moves in parallel, it can automatically clean the dirt adsorbed on the surface of the coarse filter element 201 and the fine filter element 202, preventing dirt and grease from accumulating on the coarse filter element 201 and the fine filter element 202, which would reduce the filtration effect. This ensures continuous and effective purification of exhaust gas and reduces air pollution.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
