Description

Technical Field

[0001] The utility model belongs to the technical field of biological deodorization filters, and in particular relates to a biological deodorization filter used for treating odor from kitchen waste. Background Art

[0002] A biological deodorization filter is a biological reaction device that uses microorganisms to degrade organic pollutants. It degrades organic matter through the metabolic activities of microorganisms to achieve the purpose of deodorization. It is mainly used to treat malodorous gases and wastewater. The working principle of a biological deodorization filter is to pass the malodorous gas to be treated through a packing layer, and the microorganisms in the packing layer decompose the malodorous gas into harmless substances, thereby playing the role of deodorization and wastewater treatment.

[0003] Chinese utility model patent number CN210206440U discloses an integrated deodorizing device for treating food waste. The integrated deodorizing device disclosed in the application includes an equipment shell, a pre-washing area, a biological filter, and a washing area arranged in sequence inside the equipment shell, and nozzles are installed on the tops of the pre-washing area, the biological filter, and the washing area. The sealed area at the bottom of the equipment shell is set as a chemical tank. A baffle is installed inside the chemical tank to isolate the pre-washing area, the biological filter, and the washing area. The liquid in the chemical tank below the pre-washing area is a detergent for removing acid, the liquid in the chemical tank below the biological filter is water, and the liquid in the chemical tank below the washing area is plant liquid. The filler of the biological filter is a high-efficiency composite inorganic filler. A multi-stage process is used to deodorize food waste, and the treatment effect can meet the most stringent emission standards.

[0004] Combining the description and accompanying drawings, it can be seen that the deodorization device disclosed in the application, when in use, transports malodorous gases along an intake pipe into a pre-washing zone for pre-washing. The washed malodorous gases then enter a biofilter for biological deodorization. However, due to the nature of food waste, the odor of food waste often contains some oil.

[0005] However, the above-mentioned integrated deodorization equipment used for food waste treatment does not have the function of removing grease and cannot remove the odor of food waste. As a result, when purifying the odor of food waste, grease will adhere to the surface of the pre-washing area and the body of the biological filter. This will not only reduce the efficiency of subsequent treatment of the food waste odor, but also the residual grease will lead to poor cleanliness of the biological filter itself.

[0006] Therefore, in view of the above technical problems, it is necessary to provide a biological deodorization filter for treating odor from kitchen waste.

[0007] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0033] like Figures 1 to 6 As shown, a biological deodorization filter tank for treating odor from kitchen waste in one embodiment of the present invention includes: a tank body 1, an air inlet pipe 101, a spraying, filtering and oil removal mechanism 2, and an auxiliary cleaning and oil removal mechanism 3.

[0034] like Figure 1 As shown, an air inlet pipe 101 is fixedly connected to one side of the tank body 1. The air inlet pipe 101 is used to transport the odor of kitchen waste into the tank body 1.

[0035] like Figures 1 to 2 As shown, the spraying, filtering and oil removal mechanism 2 is mounted on one side of the air inlet pipe 101. The spraying, filtering and oil removal mechanism 2 includes an oil removal tower 201, which is fixedly mounted on the side of the air inlet pipe 101 away from the tank body 1. The oil removal tower 201 provides a basis for treating the odor of food waste.

[0036] like Figure 1 As shown, a liquid storage bottom cylinder 205 is fixedly connected to the bottom of the degreasing tower body 201. The alkaline degreasing liquid and other liquids sprayed by the nozzle 204 are stored by the liquid storage bottom cylinder 205.

[0037] like Figure 1 As shown, a cap 206 is fixedly connected to the top of the oil removal tower body 201. The oil removal tower body 201, the liquid storage bottom cylinder 205 and the cap 206 cooperate to form a closed treatment tower. The closed treatment tower provides a closed treatment space for the odor of the kitchen waste.

[0038] like Figure 1 As shown, an exhaust pipe 207 is fixedly connected to the top of the cylinder cover 206. The exhaust pipe 207 is used to guide the odor of the kitchen waste processed in the oil removal tower body 201.

[0039] like Figure 1 As shown, a connecting air pipe 208 is fixedly connected between the exhaust pipe 207 and the air inlet pipe 101. The connecting air pipe 208 serves to connect the exhaust pipe 207 and the air inlet pipe 101, so as to facilitate the transportation of the degreased food waste odor along the connecting air pipe 208 and the air inlet pipe 101 into the tank body 1.

[0040] like Figures 3 to 6 As shown, a gas delivery pipe 209 is fixedly connected to one side of the oil removal tower body 201. The gas delivery pipe 209 delivers the food waste odor to be processed into the oil removal tower body 201.

[0041] It is worth noting that the air delivery pipe 209 is eccentrically positioned on one side of the degreasing tower 201, with one end of the air delivery pipe 209 located within the degreasing tower 201 positioned below the filter cylinder 202. This eccentric positioning of the air delivery pipe 209 facilitates the transport of food waste odors along the tangential direction of the degreasing tower 201 during the transport process along the air delivery pipe 209, thereby facilitating the food waste odors to rise in a spiral shape within the degreasing tower 201.

[0042] like Figures 1 to 4 As shown, a filter screen cartridge 202 is fixedly mounted in the oil removal tower body 201. The filter screen cartridge 202 is used to filter impurities and oil from the odor of the kitchen waste to be processed.

[0043] like Figures 1 to 5 As shown, a plurality of annular liquid guide tubes 203 are arranged above the filter screen cylinder 202. The nozzles 204 are assembled, fixed and liquid transported through the plurality of annular liquid guide tubes 203.

[0044] like Figures 1 to 2 As shown, multiple sets of annular liquid guide tubes 203 are fixedly connected to multiple evenly distributed nozzles 204 below. The multiple sets of nozzles 204 spray alkaline degreasing liquid onto the filter cylinder 202, which not only removes the odor of food waste in the degreasing tower 201 but also cleans the filter cylinder 202.

[0045] like Figures 1 to 5 As shown, a connecting liquid pipe 210 is connected between the multiple groups of annular liquid guiding tubes 203. The connecting liquid pipe 210 connects and conducts the multiple groups of annular liquid guiding tubes 203.

[0046] like Figures 1 to 6 As shown, a liquid adding pipe 211 is fixedly connected to one side of the degreasing tower body 201, and the liquid adding pipe 211 is connected to the annular liquid guiding pipe 203. It is convenient to transport alkaline degreasing liquid into the annular liquid guiding pipe 203 through the liquid adding pipe 211.

[0047] like Figures 1 to 2 As shown, a support ring 212 is fixedly connected to the inner wall of the oil removal tower body 201, and the support ring 212 is sleeved on the outer side of the filter screen cylinder 202. The support ring 212 plays a role in supporting and limiting the top ring 213 of the screen cylinder.

[0048] like Figures 1 to 2As shown, the top of the filter screen cylinder 202 is integrally formed with a screen cylinder top ring 213, which is arranged above the filter screen cylinder 202. The filter screen cylinder 202 is supported and limited by supporting the screen cylinder top ring 213.

[0049] like Figures 1 to 4 As shown, the auxiliary cleaning and oil removal mechanism 3 is assembled in the filter screen cartridge 202. The auxiliary cleaning and oil removal mechanism 3 includes a rotating shaft 301, which is rotatably assembled in the filter screen cartridge 202. The rotating shaft 301 plays the role of assembling, fixing and rotating driving the multiple groups of adsorption screens 303.

[0050] like Figure 1 As shown, a driving wind wheel 302 is fixedly connected to the lower part of the rotating shaft 301. The rotating shaft 301 is driven to rotate by the driving wind wheel 302 rotating under the action of airflow.

[0051] like Figures 1 to 4 As shown, multiple groups of evenly distributed adsorption screens 303 are arranged inside the filter screen cylinder 202, and the multiple groups of adsorption screens 303 are fixedly assembled on the outside of the rotating shaft 301. The multiple groups of adsorption screens 303 and the fixing frame 304 cooperate with each other to adsorb and remove oil from the odor of the kitchen waste.

[0052] like Figure 1 As shown, a fixing frame 304 is fixedly connected below the rotating shaft 301. The fixing frame 304 is arranged between the filter screen drum 202 and the driving wind wheel 302, and the fixing frame 304 is fixedly connected to the inner wall of the oil removal tower body 201. The fixing frame 304 plays a role in supporting and fixing the rotating shaft 301.

[0053] Specifically, the number of adsorption mesh plates 303 is 2 to 6 groups, and each group of adsorption mesh plates 303 is filled with adsorption fillers 305 , so that the adsorption fillers 305 can be used to adsorb and remove the odor of the kitchen waste in the filter cylinder 202 .

[0054] like Figures 1 to 4 As shown, multiple sets of evenly distributed cleaning racks 306 are fixedly mounted on the outside of the rotating shaft 301. The multiple sets of cleaning racks 306 are arranged on the outside of the filter cylinder 202. The multiple sets of cleaning racks 306 serve to connect the rotating shaft 301 with the cleaning brushes 307, so that the cleaning brushes 307 can rotate accordingly with the rotation of the rotating shaft 301 under the action of the cleaning racks 306.

[0055] like Figures 1 to 4 As shown, a cleaning brush 307 is fixedly connected to one side of the cleaning frame 306 close to the filter screen cylinder 202, and a side of the cleaning brush 307 away from the cleaning frame 306 contacts the outer wall of the filter screen cylinder 202. The grease impurities adhering to the outer side of the filter screen cylinder 202 are removed by controlling the rotation of the cleaning brush 307.

[0056] During specific use, the odor of the food waste to be processed is transported to the oil removal tower body 201 along the conveying air pipe 209. Since the conveying air pipe 209 is eccentrically arranged, the odor of the food waste to be processed will be transported to the oil removal tower body 201 along the tangential direction of the oil removal tower body 201, and will be transported in a spiral shape in the oil removal tower body 201 under the action of gas pressure. The odor of the food waste to be processed that can be transported through the filter cylinder 202 can be filtered for impurities and oil.

[0057] At the same time, alkaline degreasing liquid can be connected to the liquid adding pipe 211, and the alkaline degreasing liquid can be sprayed onto the filter cylinder 202 through multiple sets of annular liquid guide pipes 203 and nozzles 204. This can not only spray and purify the odor of food waste, but also spray and clean the filter cylinder 202 and the adsorption mesh plate 303.

[0058] Furthermore, the driving impeller 302, driven by the airflow from the air delivery pipe 209, drives the rotating shaft 301 to rotate. This rotation of the rotating shaft 301 drives the multiple sets of adsorption screens 303 and adsorption fillers 305 to rotate, thereby adsorbing and removing odors from the food waste filtered within the degreasing tower 201. Furthermore, the multiple sets of cleaning racks 306 and cleaning brushes 307 rotate with the rotation of the rotating shaft 301 to clean the outer surface of the filter cartridge 202, ensuring that the filter cartridge 202 effectively removes odors from the food waste.

[0059] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0060] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
