[0002] Kitchen waste refers to the remaining food and food residues generated during the dining process, including leftovers in dishes, fruit peels and pulps, vegetable roots and stems, animal bones and other organic waste. Kitchen waste is usually rich in water and organic matter. If it is not properly handled, it is easy to produce odor, breed bacteria and pollute the environment. In daily life, most families use trash cans to collect kitchen waste.

[0003] Kitchen waste contains a large amount of food residue and organic waste, which will decompose and rot when exposed to air and microorganisms. At the same time, the moisture in kitchen waste will promote the reproduction and activity of microorganisms, accelerating the decomposition process of organic matter. In a humid environment, microorganisms can convert organic matter into gas more quickly, causing odor to spread. Existing garbage cans often mix solids and liquids in kitchen waste, which will accelerate the corruption and fermentation process, increase the generation and spread of odor, and increase the risk of environmental hygiene and health problems.

[0004] Therefore, we propose a kitchen waste treatment device that can purify odor to solve the above problems. Utility Model Content

[0024] Furthermore, it also includes a barrel cover 2, which is installed on the top of the barrel body 101. The barrel cover 2 can effectively isolate the odorous substances in the trash can 1 and prevent them from being directly emitted into the surrounding environment. The barrel cover 2 can close the trash can 1, reduce the diffusion range of the odor, and prevent the odor from entering the indoor space through the air flow.

[0025] Furthermore, positioning rods 104 are fixedly connected to both sides of the bottom of the funnel-shaped filter 102, and the surfaces of the positioning rods 104 are slidably connected to the inner walls of the positioning blocks 103. The positioning blocks 103 are fixedly installed on the left and right sides of the inner wall of the barrel body 101. The positioning blocks 103 and positioning rods 104 are convenient for installing and disassembling the funnel-shaped filter 102, thereby shortening the time for users to install and disassemble the funnel-shaped filter 102. A handle 105 is fixedly connected to the top of the funnel-shaped filter 102, and the handle 105 is convenient for users to pull the funnel-shaped filter 102, thereby reducing the difficulty of removing the funnel-shaped filter 102 from the inside of the barrel body 101.

[0026] Furthermore, transparent windows 115 are provided on the front and rear sides of the outer wall of the barrel body 101, and the transparent windows 115 are provided to facilitate the user to observe the internal situation of the barrel body 101. When it is observed that the funnel-shaped filter 102 is filled with solid waste, the user can open the barrel cover 2 to process the solids in the funnel-shaped filter 102.

[0027] Furthermore, the barrel body 101 is made of plastic material. Plastic has good corrosion resistance and can resist corrosion from chemical substances in kitchen waste, thereby extending the service life of the barrel body 101.

[0028] Furthermore, the funnel-shaped filter screen 102 is made of polypropylene material, which has the properties of acid and alkali resistance, corrosion resistance, and aging resistance, and can effectively extend the service life of the funnel-shaped filter screen 102 .

[0029] Furthermore, the filler 109 is a kind of sawdust or peanut shells. Sawdust or peanut shells are common, cheap and easily available biological fillers. Using sawdust or peanut shells as the filler 109 can realize the reuse and resource utilization of agricultural waste.

[0030] Furthermore, the barrel cover 2 includes a cover body 201, a feeding port 202 is opened on one side of the cover body 201, and a stopper 203 is rotatably connected to the inner wall of the feeding port 202. The stopper 203 is convenient for users to pour food waste into the barrel body 101 and can reduce the generation and spread of odor.

[0031] During use, the user pulls the handle 105 upwards, and the handle 105 can drive the funnel-shaped filter 102 upward until the positioning rod 104 is separated from the inner wall of the positioning block 103, and the funnel-shaped filter 102 can be removed from the inside of the barrel body 101. Then the user can pour sawdust or peanut shells into the biological filter bed 106, and inoculate suitable microorganisms on the filled sawdust or peanut shells. The microorganisms will adhere to the surface of the sawdust or peanut shells to form a biofilm, and then the positioning rod 104 can be reinserted into the positioning block 103. The user then puts the food waste into the barrel body 101 through the feeding port 202. The solids in the food waste can be contained in the funnel-shaped filter 102, and the waste liquid in the food waste can pass through the funnel-shaped filter 102 and fall into the biological filter bed 106 along the hopper 107. When the waste liquid contacts the filler 109 inside the biological filter bed 106, the biofilm formed on the surface of the filler 109 can By reacting with organic matter in the waste liquid, the biofilm can capture odorous substances in the waste liquid through adsorption, and the strains of microorganisms attached to the biofilm can interact with odorous substances through the special structure or chemical composition of their cell surface, so that they are adsorbed on the biofilm, and the odor in the waste liquid can be effectively purified. The liquid treated with the biofilm can fall into the odor purification barrel 111 along the outlet pipe 108, and the activated carbon filter plate 112 above the inside of the odor purification barrel 111 can further filter and purify the liquid. The liquid that has been secondary purified by the activated carbon filter plate 112 can then pass through the molecular sieve filter plate 113, and the molecular sieve filter plate 113 can purify the secondary filtered liquid again so as to effectively purify the liquid. The liquid that has been purified multiple times can be discharged from the barrel body 101 along the drain pipe 114. The present equipment can ensure that the discharged liquid will not cause environmental pollution or harm the health of the user.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
