Description

Technical Field

[0001] This invention belongs to the field of waste gas purification technology for traditional Chinese medicine products, and specifically relates to a waste gas purification device and a purification method for processing traditional Chinese medicine products. Background Technology

[0002] Traditional Chinese medicine products, such as food products containing Chinese medicinal ingredients, generally refer to foods containing Chinese medicinal ingredients. For example, patent CN103549433B discloses a health food product containing Chinese medicinal ingredients with liver-protecting effects, which is prepared from the following raw materials, with the following weight percentages: jujube 5-40%, hawthorn 5-40%, Schisandra chinensis 5-40%, Poria cocos 5-40%, and wolfberry 3-30%. During the preparation process, the raw materials need to be crushed and mixed, which generates exhaust gas containing dust. Another example is patent CN104026204B, which discloses a biscuit that is both food and medicine, and its preparation method and uses. Its formula is: Prunus japonica seed, sweet potato leaf, hemp seed, mulberry, cassia seed, wolfberry, and licorice. The material is prepared by crushing or water extraction. The material is then mixed with wheat flour, sugar or sugar-free sugar, oil, dairy products, and eggs as the main raw materials, and emulsifiers, leavening agents, improvers and other auxiliary materials are added. The biscuits are made through mixing, shaping, baking, cooling and other packaging processes. During the baking process, exhaust gas containing oil fume particles is generated.

[0003] The processing of Chinese medicine food products generates a lot of waste gas. The waste gas mainly comes from raw material processing, cooking, drying, fermentation and other processes. The waste gas contains components such as dust, oil fumes and particulate matter. Therefore, the waste gas cannot be directly discharged and needs to be treated and purified multiple times before it can be discharged.

[0004] Current waste purification methods typically begin with dust and particulate matter removal, usually using filter plates. During filtration, dust and particulate matter are scraped off the filter plates. However, some smaller dust and particulate matter can move into the filter pores, clogging them and reducing subsequent filtration efficiency. Because waste may contain oil fumes, oil fume particles can adhere to the filter plates. Oil and dust particles mix and adhere to the filter plates, gradually accumulating and growing larger, eventually clogging the filter pores. Summary of the Invention

[0016] A method for purifying waste gas from the processing of traditional Chinese medicine products, using the aforementioned waste gas purification device, includes the following steps;

[0017] The exhaust gas generated from food processing is passed into the purification filter box. The exhaust gas passes through the filter plate, which filters out the dust particles in the exhaust gas. The moving cleaning box moves to scrape off the dust particles attached to the filter plate. During the scraping process, some small particles may clog the filter holes of the filter plate. The moving air intake box and the moving cleaning box move synchronously. The moving air intake box takes in air, and the gas flows into the moving cleaning box, blowing out the dust particles in the filter holes.

[0018] When the movable cleaning box moves, the lifting rotating plate drives the lifting cleaning brush downwards, bringing it into contact with the filter plate. The cleaning brush, coated with cleaning fluid, cleans the oil residue adhering to the filter plate. When the cleaning brush is no longer in contact with the filter plate, the lifting rotating plate rotates, causing the lifting cleaning brush to rotate as well. During rotation, the brush enters the cleaning fluid box, leaving it coated with cleaning fluid. The cleaning brush then moves to a position below the lifting rotating plate, while the lifting sponge block moves to a position above it. The lifting rotating plate then drives the lifting sponge block upwards, allowing it to absorb and clean the cleaning fluid from the filter plate surface. When the sponge block reaches its highest point, the movable squeezing plate moves downwards to contact and squeeze the sponge block, expelling the absorbed cleaning fluid. After squeezing, the lifting rotating plate drives the sponge block downwards. When the sponge block is no longer in contact with the filter plate, the lifting rotating plate rotates again, causing the sponge block to rotate. The sponge block moves to a position below the lifting rotating plate, while the cleaning brush moves to a position above it.

[0019] Preferably, the traditional Chinese medicine product is a food product containing traditional Chinese medicine.

[0020] Preferably, the Chinese medicine product can also be a prepared slice of Chinese medicine or a Chinese medicine preparation using existing technology.

[0021] Compared with the prior art, the present invention provides a waste gas purification device and a purification method for processing traditional Chinese medicine products, which has the following beneficial effects:

[0022] 1. The exhaust gas generated from food processing is introduced into the purification filter box. The exhaust gas passes through the filter plate, which filters out dust particles in the exhaust gas. The moving cleaning box moves to scrape off the dust particles attached to the filter plate. During the scraping process, some small particles may clog the filter holes of the filter plate. The moving air intake box moves synchronously with the moving cleaning box. The moving air intake box takes in air, and the gas flows into the moving cleaning box, blowing out the dust particles in the filter holes; this prevents some dust particles from clogging the filter holes and reducing the exhaust gas purification efficiency.

[0023] 2. When the mobile cleaning box moves, the lifting rotating plate drives the lifting cleaning brush to move downward. The lifting cleaning brush contacts the filter plate. The mobile cleaning brush contains cleaning fluid, which cleans the oil stains attached to the filter plate. This prevents the oil stains from mixing with dust particles and adhering to the filter plate, clogging the filter holes, reducing purification efficiency, and avoiding damage to the filter plate caused by prolonged oil stains.

[0024] 3. When the lifting cleaning brush is no longer in contact with the filter plate, the lifting rotating plate rotates and drives the lifting cleaning brush to rotate. During the rotation, the lifting cleaning brush enters the cleaning liquid box, so that the lifting cleaning brush is covered with cleaning liquid. The lifting cleaning brush moves to the position below the lifting rotating plate, and the lifting sponge block moves to the position above the lifting rotating plate. The lifting rotating plate drives the lifting sponge block to move upward. The lifting sponge block absorbs and cleans the cleaning liquid on the surface of the filter plate. When the lifting sponge block moves to the highest position, the moving extrusion plate moves downward to contact and squeeze the lifting sponge block, squeezing out the cleaning liquid absorbed by the sponge block and collecting the cleaning liquid to prevent dust particles from mixing with the cleaning liquid.

[0025] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0039] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0040] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0041] For examples, please refer to Figure 1 - Figure 10This embodiment discloses an exhaust gas purification device, including a purification filter box 1, a filter assembly 2 and a cleaning assembly 3. The filter assembly 2 includes two filter plates 201, which are disposed inside the purification filter box 1.

[0042] The cleaning component 3 includes a movable air intake box 301, a movable cleaning box 302, a lifting rotating plate 303, a lifting cleaning brush 304, a lifting sponge block 305, a movable squeezing plate 306, and a cleaning liquid box 307. The movable air intake box 301 and the movable cleaning box 302 are located on both sides of the filter plate 201, the lifting rotating plate 303 is set inside the movable cleaning box 302, the lifting cleaning brush 304 is located above the lifting rotating plate 303, the lifting sponge block 305 is located below the lifting rotating plate 303, the movable squeezing plate 306 is located above the lifting cleaning brush 304, and the cleaning liquid box 307 is located below the lifting rotating plate 303.

[0043] The movable air intake box 301 and the movable cleaning box 302 are in contact with the filter plate 201 and can move synchronously. The lifting rotating plate 303 can move vertically inside the movable cleaning box 302. When the lifting rotating plate 303 moves to a lower position inside the movable cleaning box 302, the lifting rotating plate 303 can rotate, causing the lifting cleaning brush 304 to move to the lower position of the lifting rotating plate 303 and the lifting sponge block 305 to move to the upper position of the lifting rotating plate 303. When the movable squeezing plate 306 moves downward, it can contact and squeeze the lifting sponge block 305. When the lifting rotating plate 303 rotates, the lifting cleaning brush 304 can enter the cleaning liquid box 307.

[0044] In use, the exhaust gas generated from food processing is introduced into the purification filter box 1. The exhaust gas passes through the filter plate 201, which filters out dust particles in the exhaust gas. The moving cleaning box 302 moves to scrape off the dust particles attached to the filter plate 201. During the scraping process, some small particles may clog the filter holes of the filter plate 201. The moving air intake box 301 and the moving cleaning box 302 move synchronously. Air is introduced into the moving air intake box 301 and flows into the moving cleaning box 302, blowing out the dust particles in the filter holes. This prevents some dust particles from clogging the filter holes and reducing the exhaust gas purification efficiency.

[0045] When the movable cleaning box 302 moves, the lifting rotating plate 303 drives the lifting cleaning brush 304 downward, bringing it into contact with the filter plate 201. The movable cleaning brush, containing cleaning fluid, cleans the oil stains adhering to the filter plate 201. When the lifting cleaning brush 304 is no longer in contact with the filter plate 201, the lifting rotating plate 303 rotates, causing the lifting cleaning brush 304 to rotate as well. During this rotation, the lifting cleaning brush 304 enters the cleaning fluid box 307, leaving cleaning fluid adhering to it. The lifting cleaning brush 304 then moves to a position below the lifting rotating plate 303, while the lifting sponge block 305 moves to a position above it. The lifting rotating plate 303 drives the lifting sponge block 305 upward, allowing it to absorb and clean the cleaning fluid remaining on the surface of the filter plate 201. When the lifting sponge block 305 moves to its highest position, the moving extrusion plate 306 moves downward to contact and extrude the lifting sponge block 305, squeezing out the cleaning liquid absorbed by the sponge block. After extrusion, the lifting rotating plate 303 drives the lifting sponge block 305 downward. When the lifting sponge block 305 is no longer in contact with the filter plate 201, the lifting rotating plate 303 rotates and drives the lifting sponge block 305 to rotate. The position of the lifting sponge block 305 moves below the lifting rotating plate 303, and the position of the cleaning brush moves above the lifting rotating plate 303. This cleans the oil stains attached to the filter plate 201, preventing oil stains from mixing with dust particles and adhering to the filter plate 201, clogging the filter holes, reducing purification efficiency, and avoiding damage to the filter plate 201 caused by prolonged oil stains. The cleaning liquid is collected to prevent dust particles from mixing with the cleaning liquid.

[0060] This embodiment also discloses a method for purifying waste gas from the processing of traditional Chinese medicine products, which uses the above-mentioned waste gas purification device and includes the following steps;

[0061] The waste gas generated from food processing is introduced into the purification filter box 1. The waste gas passes through the filter plate 201, which filters the dust particles in the waste gas. The moving cleaning box 302 moves to scrape off the dust particles attached to the filter plate 201. During the scraping process, some small particles may block the filter holes of the filter plate 201. The moving air intake box 301 and the moving cleaning box 302 move synchronously. The moving air intake box 301 takes in air, and the gas flows into the moving cleaning box 302, blowing out the dust particles in the filter holes.

[0062] When the movable cleaning box 302 moves, the lifting rotating plate 303 drives the lifting cleaning brush 304 to move downwards. The lifting cleaning brush 304 contacts the filter plate 201. The movable cleaning brush contains cleaning fluid, which cleans the oil stains adhering to the filter plate 201. When the lifting cleaning brush 304 is no longer in contact with the filter plate 201, the lifting rotating plate 303 rotates, driving the lifting cleaning brush 304 to rotate as well. During this rotation, the lifting cleaning brush 304 enters the cleaning fluid box 307, leaving cleaning fluid adhering to it. The lifting cleaning brush 304 moves to a position below the lifting rotating plate 303, and the lifting sponge block 305 moves to a position above the lifting rotating plate 303. 303 drives the lifting sponge block 305 to move upward, and the lifting sponge block 305 absorbs and cleans the cleaning liquid on the surface of the filter plate 201. When the lifting sponge block 305 moves to the highest position, the moving extrusion plate 306 moves downward to contact and squeeze the lifting sponge block 305, squeezing out the cleaning liquid absorbed by the sponge block. After the squeezing is completed, the lifting rotating plate 303 drives the lifting sponge block 305 to move downward. When the lifting sponge block 305 is no longer in contact with the filter plate 201, the lifting rotating plate 303 rotates and drives the lifting sponge block 305 to rotate. The position of the lifting sponge block 305 moves to below the lifting rotating plate 303, and the position of the lower cleaning brush moves to above the lifting rotating plate 303.
