Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment equipment, and in particular to a kitchen waste sorting and impurity removal device. Background Technology

[0002] With the development of society and the economy and the improvement of people's living standards, the amount of food waste generated is increasing day by day, and it has become an important part of urban household waste. Food waste is characterized by high water content, high organic matter content, easy decomposition, and complex composition, often mixed with impurities such as bones, plastics, paper, and metals. If it is discharged or landfilled directly without treatment, it will not only occupy a large amount of land resources, but also cause serious pollution to soil, water sources and air.

[0003] Therefore, effective treatment and resource utilization of food waste are crucial. Before subsequent resource utilization processes such as composting, anaerobic digestion, and feed production, food waste usually needs to be pre-treated. Key steps include removing large pieces or non-organic impurities and reducing moisture content (dehydration / draining) to improve subsequent processing efficiency and product quality.

[0004] However, existing technologies still have some shortcomings in the pretreatment of food waste. For example, some equipment struggles to effectively process food waste with high moisture content and viscosity, easily leading to blockages and poor solid-liquid separation. Furthermore, many devices lack a mechanism for flexibly adjusting the moisture content of the final discharged solid material after initial dewatering, making it difficult to adapt to the material state requirements of different subsequent resource recovery processes.

[0005] To address this, we propose a sorting and impurity removal device for kitchen waste.

[0006] Information sources and related content.

[0007] Therefore, it is necessary to provide a new sorting and impurity removal device for kitchen waste to solve the above-mentioned technical problems. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 3 The present invention provides a kitchen waste sorting and impurity removal device, which includes: a screening box 5, a top cover 1, a spiral conveying mechanism, a drain pipe 7, a discharge pipe 11, and a drainage adjustment mechanism.

[0025] The screening box 5 has front support legs 8 fixedly connected to both sides of its left end, and rear support legs 12 fixedly connected to both sides of its right end. The rear support legs 12 are higher than the front support legs 8, so the screening box 5 is shaped with the left side lower than the right side. The top cover 1 is fastened to the upper surface of the screening box 5, and a feed hopper 4 is fixedly connected to the top cover 1. The screening box 5 is equipped with a spiral conveying mechanism, which includes a drive motor 6, a rotating shaft 9, and spiral blades 10. The rotating shaft 9 is rotatably connected between the inner walls of the two sides of the screening box 5. Spiral blades 10 are fixedly connected to the surface of the rotating shaft 9, and the left side of the rotating shaft 9 passes through the side wall of the screening box 5 and is fixedly connected to the output end of the drive motor 6 through a coupling. The drive motor 6 is fixed to the left side of the screening box 5. A drain pipe 7 is threadedly connected to the left side of the lower surface of the screening box 5. A matching screen 13 is fixedly connected to the upper end of the drain pipe 7. A feed pipe 11 is fixedly connected to the right side of the lower surface of the screening box 5.

[0026] This invention achieves efficient solid-liquid separation and impurity removal. Specifically, kitchen waste enters the screening box 5 from the feed hopper 4. Because the rear support leg 12 is higher than the front support leg 8, the entire screening box 5 is tilted from left to right. This allows the liquid in the incoming kitchen waste to naturally converge to the lower left side under the influence of gravity. The spiral conveying mechanism located inside the screening box 5 propels the kitchen waste forward from left to right along the length of the screening box 5 during operation. During this process, the tilted design, combined with the stirring and pushing action of the spiral blades, accelerates the separation of the liquid and solid phases in the material. The separated liquid is discharged through the drain pipe 7 located on the lower left side of the screening box 5. The screen 13 at the upper end of the drain pipe 7 effectively prevents larger solid particles from entering the drain pipe 7, preventing blockage and ensuring smooth discharge of the liquid. The solid material, after preliminary draining and impurity separation, is pushed to the right end of the screening box 5 by the spiral blades 10 and discharged through the discharge pipe 11.

[0027] It should be noted that the inclined design of the screening box 5 utilizes the principle of gravity, combined with the propulsion of the spiral conveying mechanism, to effectively promote the rapid separation and discharge of liquid in the kitchen waste, thereby improving the solid-liquid separation efficiency. Furthermore, the screen 13 installed on the drain pipe 7 can screen out large impurities, preventing them from entering and clogging the drain pipe, thus ensuring the continuous and stable operation of the equipment. In addition, the spiral blades 10 rotate stably under the action of the drive motor 6, which can smoothly and effectively transport the kitchen waste from the feed end to the discharge end, reducing the residence time of the material in the screening box and reducing the risk of adhesion and blockage.

[0028] The discharge pipe 11 is equipped with a drainage adjustment mechanism, which includes an adjustment pipe 14, a rack 17, and a crank handle 15. The adjustment pipe 14 is slidably connected to the inner wall of the discharge pipe 11. An adjustment groove 16 is opened on the front end face of the adjustment pipe 14. A rack 17 is fixedly connected to one side of the adjustment groove 16. The crank handle 15 is rotatably connected to the rear end face of the discharge pipe 11. The crank handle 15 passes through the pipe wall of the discharge pipe 11 and is fixedly connected to a gear. The gear is located in the adjustment groove 16 and meshes with the rack 17.

[0029] In addition, the drainage adjustment mechanism provided in the feed pipe 11 of this device significantly increases the adjustment function of the equipment and its adaptability to different processing processes. Since subsequent resource treatment (such as composting, anaerobic digestion, feed production, etc.) has different requirements for the moisture content of the material, and existing equipment often has difficulty in flexibly adjusting the dryness and wetness of the final discharged solids, this drainage adjustment mechanism changes the drainage state of the solid material before discharge by adjusting the sliding position of the adjustment pipe 14 in the feed pipe 11.

[0030] The specific operation involves rotating the crank handle 15, which drives the gear and rack 17 to mesh and move, thereby controlling the extension and retraction position of the regulating pipe 14. This, in turn, adjusts the effective discharge space or draining time of solid materials, ultimately changing the moisture content of the discharged solid materials. This adjustable function allows operators to conveniently adjust the humidity of the discharged materials according to the specific needs of the downstream processing technology, ensuring that the material condition meets the optimal requirements for subsequent processing, thus improving the efficiency of the entire food waste treatment process and the quality of the resource-based products.

[0031] A baffle plate 3 is rotatably connected between the inner walls of both sides of the feeding hopper 4. A spring is connected between the lower surface of the baffle plate 3 and the feeding hopper 4. The upper surface of the feeding hopper 4 is provided with placement grooves 2 for pouring, which makes it convenient for operators to stabilize the container when pouring kitchen waste.

[0032] It should be noted that when kitchen waste enters through the feed hopper 4, the baffle plate 3 allows the material to pass smoothly into the screening box 5 below. When the feeding process is over, the baffle plate 3 can return to its position under the action of the spring or with the assistance of the spring, thereby blocking the feed inlet and playing a covering role to prevent debris from falling in accidentally, thus improving the safety performance of the device.

[0033] In summary, this kitchen waste sorting and impurity removal device mainly consists of an inclined screening box 5, an internal spiral conveying mechanism, a drain pipe 7, and a drainage adjustment mechanism. The screening box 5 is set with the left side lower than the right side. It utilizes gravity in conjunction with the pushing and stirring of the spiral blades 10 to achieve efficient solid-liquid separation of materials. The liquid is discharged through the drain pipe 7 with a screen 13 to prevent blockage, while the solid is discharged through the feeding pipe 11. Its moisture content can be flexibly controlled by the drainage adjustment mechanism adjustment pipe 14 to adapt to different subsequent processing requirements. The baffle plate 3 of the feed hopper 4 can be closed after feeding, making it suitable for the pretreatment of kitchen waste.

[0034] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
