TECHNICAL FIELD
[0001] The present application relates to the field of environmental protection, in particular to an environmental protection equipment for kitchen waste treatment. BACKGROUND
[0002] With the acceleration of urbanization, the total amount of household waste continues to grow, of which kitchen waste accounts for usually 40% to 60%. Kitchen waste has the characteristics of high moisture content, easy to rot, produce odor and breed bacteria. If it is randomly filled or incinerated, not only will it cause leachate to pollute the soil and groundwater, but also will release a large amount of greenhouse gases, aggravating the environmental burden. Therefore, how to efficiently, safely and environmentally treat kitchen waste has become an important issue in urban solid waste management and ecological environment protection.
[0003] The core goal of kitchen waste treatment is not only to reduce, but also to achieve harmlessness and resource utilization. Through reasonable treatment device, kitchen waste can be crushed, dewatered and separated, the liquid part is used for fermentation to make fertilizer or biogas, and the solid residue is converted into organic fertilizer through compression or composting, thus forming an ecological chain of recycling. This treatment method not only reduces the risk of environmental pollution, but also effectively saves resources, promotes green and low-carbon lifestyle, and meets the environmental protection trend under the "double carbon target"
[0004] Most of the existing kitchen waste treatment equipment has relatively simple structure, usually only has basic crushing and discharge functions. In the use process, due to the lack of effective pre-classification means in the feeding link, some large-sized kitchen waste directly enters the crushing unit, not only increasing the crushing difficulty, but also easily causing machine jamming or cutter damage. In addition, small pieces of metal may be mixed in part of the kitchen waste, and the existing equipment lacks separation function. Once it enters the crushing process, it not only causes wear and tear to the internal structure of the equipment, but also causes waste of materials.
[0005] In addition, most of the existing devices adopt integral connection structure, and the cleaning and maintenance link needs to disassemble the whole machine, which is cumbersome and inconvenient for daily maintenance, and is easy to cause internal accumulation of residues, thus breeding odor and bacteria. On the other hand, the solid-liquid separation and crushing functions are often carried out separately, the treatment process is relatively fragmented, resulting in low treatment efficiency, limited kitchen waste reduction and resource utilization effect. Therefore, the existing technology still has obvious deficiencies in safety, convenience and environmental protection. SUMMARY
[0006] In view of the deficiencies of the prior art, the present application provides an environmental protection equipment for kitchen waste treatment, which solves the problems of simple structure of the existing kitchen waste treatment device, lack of pre-screening function during feeding, difficulty in disassembly during maintenance, and solid-liquid separation after crushing.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Those skilled in the art should connect all electrical components and their compatible power supplies to each other using wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working sequence of each electrical component in the following working principle to complete the electrical connection. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process, and will not explain the electrical control.
[0031] Please see Figures 1-6 The present invention provides a technical solution:
[0032] This device mainly consists of three parts: a feeding structure, a crushing structure, and a solid-liquid separation structure. It achieves overall stability and movement adjustment through a support frame and a displacement structure. Its working process is as follows:
[0033] Waste disposal and pretreatment:
[0034] Workers pour garbage into the hopper, which tilts under the action of an electric slide rail and hydraulic cylinder. A second filter and magnetic rod pre-screen and separate large impurities and metal objects. The kitchen waste is then fed into the feeding hopper. The tray in the hopper is height-adjustable, driven by a dual-axis motor and lead screw, to control the feed rate. A servo motor drives a spiral rotor to evenly push the material into the long pipe and into the feed tube. An infrared sensor on the top of the hopper monitors the garbage depth in real time to prevent overload.
[0035] Crushing process:
[0036] The screened waste enters the crushing structure through the feed pipe. The sealing cover, activated by a hydraulic cylinder, seals against the top of the storage tank to prevent odors and liquid leakage. The internal multi-stage crushing components sequentially shear and grind the waste. Some models also feature a rotating connecting rod and blades inside the feed pipe, achieving three-stage step crushing to achieve a particle size of 5-10mm, ensuring smooth subsequent separation.
[0037] Solid-liquid separation:
[0038] The crushed material directly falls into the storage barrel, the first motor drives the driving wheel and the driven wheel to rotate the storage barrel, the blades on the barrel wall stir the material, and the liquid penetrates into the storage barrel through the filter screen. The solid part is gradually concentrated at the bottom of the storage barrel, and the funnel-shaped structure helps to discharge and discharge residue. The liquid is discharged through the liquid outlet pipe, and the solid is discharged through the discharge pipe after the cover driven by the hydraulic cylinder is opened, avoiding the mixing of solid and liquid.
[0039] Discharge and resource utilization:
[0040] The separated liquid can be further transported to a fermentation or biogas system for reuse, and the solid residue is converted into organic fertilizer after compression or composting, realizing resource utilization.
[0041] Example one: an environmental protection equipment for kitchen waste treatment, comprising a support 1 composed of a top base plate and four corner legs, a displacement structure is arranged at the bottom of the leg, a solid-liquid separation structure is arranged at the bottom of the support 1, a crushing structure is arranged on the support 1 and moves up and down to engage with the solid-liquid separation structure, one side of the support 1 is provided with a feeding structure, the feeding structure pre-screens the material, and the feeding structure communicates with the crushing structure to feed the material into the solid-liquid separation structure;
[0042] The environmental protection equipment is composed of a support 1, a feeding structure, a crushing structure and a solid-liquid separation structure. The garbage is first pre-screened by the feeding structure, and the large foreign matters are preliminarily removed. The finer garbage enters the crushing structure. The crushing structure moves up and down to engage with the solid-liquid separation structure, realizing closed crushing and preventing splashing. The crushed garbage directly falls into the solid-liquid separation structure, realizing automatic treatment.
[0043] Through mechanical linkage, continuous feeding, crushing and separation are realized, reducing manual intervention. In the experiment of treating 150 kg of kitchen waste per hour, the solid content of the separated liquid is less than 3%, and the water content of the solid is reduced to below 50%.

When the cover 14 is pressed together, the sealing ring is in contact with the discharge port, achieving pipeline closure. The conical design prevents material accumulation. The generatrix of the cone is parallel to the center line of the lower surface of the connecting rod in the same plane, making the crushing more uniform.
[0057] The hydraulic drive is used to control the opening and closing of the discharge port, preventing the mixing of solid and liquid when the treatment is not complete. The hydraulic cylinder has a closing pressure of 0.3 MPa and can withstand about 50 kg of solid slag without leakage.
