Organic garbage treatment system

Abstract

The invention relates to an organic garbage treatment system. A tank body of a feeding tank is vertically arranged on an upper bracket of a rack; a stirring motor is arranged on a top cover of the tank body and is connected with a stirring shaft arranged in the tank body; a weighing sensor is arranged between each supporting seat and the rack; a discharge opening in the bottom of the tank body is connected and communicated with a feeding box of an extrusion dehydration device; an electric valve is arranged at the discharge opening of the tank body; the extrusion dehydration device is transversely arranged on a base and is positioned on the lower part of the feeding tank; a squeezing motor is connected with one end of a main shaft through an output shaft of a speed reducer; a filter cartridge comprises the feeding box on the front upper part and multiple semicircular filter screen units; the feeding box and the multiple filter screen units are assembled to form a closed cavity; and a conical surface of a pressing cone of a solid slag discharging mechanism is blocked at a slag outlet of the filter cartridge. The organic garbage treatment system disclosed by the invention has the characteristics that the structure is compact, the loss of organic matters can be reduced, the grease content in free water is improved, the discharging dryness is stable, the solid-liquid separation efficiency can be improved, and the maintenance and overhaul are convenient.

Description

technical field [0001] The invention relates to an organic waste treatment system, which belongs to the technical field of organic waste treatment. Background technique [0002] Catering garbage refers to the garbage generated in residents' daily life and activities such as food processing, catering services, and unit meals. Its main sources are home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. Catering waste contains extremely high moisture and organic matter, which is easy to rot and produces stench. After proper treatment and processing, it can be transformed into new resources. The high organic matter content makes it possible to be used as fertilizer and feed after strict treatment, and can also produce biogas for fuel or power generation. The oil part can be used to prepare biofuels. [0003] In order to make full use of the organic matter in the kitchen waste to generate biogas and recover oil at the same time...

AI Technical Summary

Problems solved by technology

However, the composition of organic waste is very complex, and there are problems of filter blockage and serious wear and tear.

In addition, when the amount of food waste added is small or the feeding speed of food waste is slow, it will be directly pushed out under the action of the extrusion screw after entering the filter cartridge first, resulting in the inability to effectively achieve the purpose of extrusion, and thus dehydration The effect is not ideal, and the dehydration rate is low

For this reason, CN211683628U discloses "a kitchen waste screw extrusion dehydrator", which adopts variable diameter screw extrusion dehydration, and can adjust the extrusion force according to the difference in the dehydration moisture content of food waste, but the back pressure of the pressure cone The pressure is only realized by the elasticity of the spring. Long-term operation will lead to elastic failure, thereby reducing the processing efficiency of the equipment. In addition, because the adjustment of the extrusion pressure needs to be manually adjusted, the composition of the food waste is very complicated, which may easily lead to uneven dryness of the output. Stablize

In the existing solid-liquid separation treatment system, the feeding hopper only plays the role of feeding materials, and cannot pretreat food waste, resulting in large loss of organic matter and low oil recovery rate
