Description

Technical Field

[0001] The present invention belongs to the technical field of waste gas purification for traditional Chinese medicine-based foods. Specifically, it particularly relates to a waste gas purification device and a purification method for traditional Chinese medicine product processing. Background Art

[0002] Traditional Chinese medicine products such as traditional Chinese medicine-based foods generally refer to foods containing traditional Chinese medicine ingredients. For example, patent CN103549433B discloses a traditional Chinese medicine health food with the effect of protecting the liver and the gallbladder, which is prepared from the following raw materials, and the weight percentage of each component is: Chinese date 5 - 40%, raw hawthorn 5 - 40%, Schisandra chinensis 5 - 40%, Poria cocos 5 - 40%, wolfberry fruit 3 - 30%. During the preparation process, the raw materials need to be crushed and mixed, thus generating waste gas containing dust; for example, patent CN104026204B discloses a food and medicine dual-purpose traditional Chinese medicine food biscuit and its preparation method and uses, and its formula is: Prunus davidiana, sweet potato leaves, Cannabis sativa seeds, mulberry, Cassia obtusifolia, wolfberry fruit, liquorice. The materials are obtained by preparation methods such as crushing or water extraction, and then the materials are made into biscuits with wheat flour, sugar or sugar-free, oil, dairy products, eggs as the main raw materials, adding emulsifiers, leavening agents, modifiers and other auxiliary materials through processes such as dough mixing, shaping, baking, and cooling for packaging; waste gas containing oil fume particles will be generated during the baking process.

[0003] During the processing of traditional Chinese medicine-based foods, a relatively large amount of waste gas will be generated. The waste gas mainly comes from links such as raw material processing, cooking, drying, and fermentation. Components such as dust, oil fume, and particulate matter will exist in the waste gas. Therefore, the waste gas cannot be directly discharged and needs to be processed and purified multiple times before it can be discharged;

[0004] Existing waste gas purification usually first purifies dust and particulate matter, usually using filter plates for filtration. During the filtration process, the dust and particulate matter on the filter plates are scraped off, but some smaller dust and particulate matter will move into the filter holes, clogging the filter holes and reducing the subsequent filtration efficiency; because there is oil fume in the waste gas, the oil fume particles will adhere to the filter plates, and the oil stains and dust particles will be mixed and adhere to the filter plates, gradually accumulating and growing larger, clogging the filter holes.

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

[0022] 1. The exhaust gas generated by food processing is introduced into the purification and filtration box. The exhaust gas passes through the filter plate, and the filter plate filters the dust particles in the exhaust gas. The mobile cleaning box moves to scrape the dust particles attached to the filter plate. During the scraping process, some small particles may block the filter holes of the filter plate. The mobile air inlet box moves synchronously with the mobile cleaning box, and the mobile air inlet box intakes air, and the gas flows into the mobile cleaning box, blowing out the dust particles in the filter holes; preventing some dust particles from blocking the filter holes and reducing the exhaust gas purification efficiency.

[0023] 2. When the mobile cleaning box moves, the lifting and rotating plate drives the lifting cleaning brush to move downward. The lifting cleaning brush contacts the filter plate.

[0024] 3. When the lifting cleaning brush is not in contact with the filter plate, the lifting rotating plate rotates and drives the lifting cleaning brush to rotate. During the rotation of the lifting cleaning brush, it enters the cleaning liquid box, so that the cleaning liquid adheres to the lifting cleaning brush. The position of the lifting cleaning brush moves to below the lifting rotating plate, and the position of the lifting sponge block moves to above the lifting rotating plate. The lifting rotating plate drives the lifting sponge block to move upward, and the lifting sponge block adsorbs and cleans the cleaning liquid remaining 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 adsorbed by the sponge block to collect the cleaning liquid and prevent the dust particles from mixing with the cleaning liquid.
