Description

Technical Field

[0001] This invention relates to the field of waste treatment separation equipment technology, specifically a separation device for waste resource recovery. Background Technology

[0002] With the accelerating urbanization process and the continuous improvement of residents' living standards in my country, the amount of urban and rural domestic waste generated is increasing year by year, among which kitchen waste accounts for a very high proportion, usually accounting for 40%-60% of the total domestic waste. Kitchen waste is characterized by high water content, high organic matter content, easy decomposition and odor, and complex oil composition. It is not only an important source of environmental pollution, but also a recyclable material with great resource utilization value. Its organic matter can be used to make organic fertilizer and biogas, and its oil can be recycled and reused in industry. How to efficiently, cleanly, and automatically reduce, harmlessly, and recycle kitchen waste has become a key research direction in the field of environmental protection equipment, and a key breakthrough in solving the contradiction between urban environmental governance and resource recycling.

[0003] Currently, common kitchen waste treatment equipment and traditional methods on the market generally suffer from the following technical defects in practical applications, making it difficult to meet the high standards of modern waste resource utilization: 1. Poor crushing and grinding effects, insufficient refinement of waste. Most existing equipment uses only a single crushing structure (such as a single set of crushing blades), lacking the coordinated operation of multi-stage chopping and fine grinding. Bones, fruit shells, and fibrous materials in kitchen waste are difficult to be fully refined. The insufficiently refined waste particles are large, directly leading to incomplete solid-liquid separation, high moisture content in the residue, and low organic matter extraction efficiency, seriously affecting the resource utilization effect and even failing to meet the feed requirements for subsequent fermentation, fertilizer production, and other resource-based treatments.

[0004] 2. Fixed grinding gap, unable to adapt to different materials: Traditional kitchen waste processing devices mostly have a fixed grinding structure with an unadjustable grinding gap. This makes it impossible to adapt to different types of kitchen waste (such as vegetables, meat, bones, and fruit peels), hardness, and dryness / wetness. When processing hard materials (such as bones and fruit pits), problems such as insufficient grinding, equipment jamming, and excessive wear of grinding parts easily occur. When processing soft materials (such as vegetable leaves and fruit peels), problems such as over-crushing, high energy consumption, and excessively viscous slurry occur. The equipment has poor versatility and is limited in its applicable scenarios.

[0005] 3. The feeding and crushing processes are prone to splashing, polluting the environment and posing safety hazards. In existing equipment, during feeding and high-speed crushing, kitchen waste (especially finely chopped waste containing moisture) easily splashes upwards from the feed inlet, causing a dirty and unpleasant working environment, spreading odors, and potentially causing pollution or mechanical injury to operators. Most equipment relies solely on simple covers to prevent splashing, which cannot fundamentally solve the problem, resulting in low environmental friendliness and safety, and failing to meet the hygiene and safety requirements of industrial production and civilian applications.

[0006] 4. The solid-liquid separation method is simple, and the dewatering effect is not ideal. Traditional equipment mostly relies on natural filtration or simple centrifugation to achieve solid-liquid separation. A large amount of water (usually above 60%) remains in the slag. The separated slag is bulky, has high transportation costs, and is prone to secondary decomposition, making it difficult to meet the core requirements of waste reduction. The lack of an active extrusion dewatering structure makes it impossible to meet the actual requirements of high dryness output and subsequent resource utilization.

[0007] In summary, existing kitchen waste processing equipment has significant shortcomings in terms of crushing and grinding effect, adjustable gap, anti-splashing, and extrusion dehydration, making it difficult to meet the requirements of modern waste resource utilization. Therefore, developing an integrated separation device that can achieve multi-stage crushing, adjustable gap, anti-splashing, automatic extrusion dehydration, convenient discharge, and water-oil separation function, and solving the above-mentioned technical problems, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0018] In a preferred embodiment of the separation device for waste resource recovery according to the present invention, the inlet end of the water-oil separator is connected to the lower end of the outer casing via a pipe.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by sequentially arranging crushing discs and adjusting grinding discs from top to bottom, allows kitchen waste to undergo continuous and coordinated processing within the same crushing section. This processing includes crushing and dispersing by the crushing blades, secondary chopping by the edge of the side-cutting blades, and relative grinding and refining by the upper and lower grinding discs. The crushing and grinding processes work together in an orderly manner, effectively refining difficult-to-process components such as high-fiber and hard particles in kitchen waste. This significantly improves the uniformity and fluidity of the waste slurry, achieving multi-stage coordinated crushing and fine grinding. The homogenization of waste treatment is significantly enhanced, fundamentally improving the problems of single crushing, coarse particles, and difficult subsequent separation in traditional equipment. This provides a stable and reliable pretreatment foundation for solid-liquid separation and resource utilization in the subsequent filter bottom cylinder.

[0020] 2. The grinding gap can be dynamically adjusted, which broadens the application range and improves grinding stability. It adopts a double-headed electric telescopic rod with an adjustment structure of top column and lower grinding disc. The grinding chamber gap between the upper and lower grinding discs can be adjusted in real time according to the type of material, hardness and processing conditions. This enables fine and adaptable grinding of kitchen waste of different components, avoiding jamming and wear caused by hard materials, and preventing excessive crushing of soft materials, thus reducing energy consumption and equipment wear.

[0021] 3. The use of a ring-shaped water curtain to suppress dust and prevent splashing improves the safety of the working environment from the source. A ring-shaped water spray structure is set at the feed channel of the connecting pipe seat of the water hood. The flat nozzle forms a continuous closed water curtain, which forms a physical barrier during the feeding and crushing process, effectively suppressing the splashing of waste and significantly improving the operating environment.

[0022] 4. Combining filtration and forced extrusion significantly improves solid-liquid separation. The gravity filtration of the filter cartridge at the bottom of the filter cylinder and the mechanical extrusion dewatering of the pressure plate are integrated into one unit. The ground material first undergoes preliminary solid-liquid separation through the filter cartridge, and then achieves deep dewatering through the relative extrusion of the pressure plate and the material support plate. This greatly reduces the moisture content of the slag and achieves efficient waste reduction. Compared with traditional natural sedimentation and simple filtration methods, the separation is more thorough and the output dryness is higher, which facilitates subsequent resource utilization and transportation, and significantly improves the efficiency and effectiveness of waste treatment.

[0037] In some embodiments of the present invention, reference is made to... Figure 1 and Figure 2As shown, the inlet end of the water-oil separator 600 is connected to the lower end of the outer casing 330 via a pipe.

[0038] It should be noted that the water-oil separator 600 is existing technology, and such products are readily available. The embodiments of this application do not specifically limit its structure, and its specific structure is not within the scope of protection claimed in this application.

[0039] By adding a water-oil separation stage, the resource can be fully recycled and secondary pollution can be avoided. The oily liquid separated by the outer shell 330 of the filter bottom cylinder 300 is concentrated and introduced into the water-oil separator 600 to achieve three-stage separation and recycling of water phase, oil phase and solid phase. The oil resources can be recycled and reused, avoiding the direct discharge of oily wastewater, which would cause pipe blockage, environmental pollution and resource waste.

[0040] The core working principle of this invention is as follows: feeding and splash prevention are achieved through the water-filling hood 400; the multi-stage crushing and adjustable grinding of the crushing section 200 is used to refine the waste; the bottom filter section 300 is used to achieve preliminary solid-liquid separation; the cooperation between the extrusion structure and the sliding receiving section 500 is used to achieve deep dehydration of the slag; and the water-oil separator 600 is used to achieve water-oil separation of the liquid, ultimately achieving the reduction, harmlessness and resource utilization of kitchen waste.

[0041] The detailed working steps are as follows: Step 1: Connect the water supply pipe connector 432 to the external water supply equipment to ensure a stable water supply. Start the water-oil separator 600 and control the single-head electric telescopic rod 520 to extend, driving the material tray 530 to rise until the material tray 530 is tightly fitted with the lower opening of the filter cartridge 312.

[0042] Step 2: Turn on the external water supply equipment. Water enters the water storage ring shell 431 through the water supply pipe connector 432 and is sprayed into the connecting pipe seat 410 through multiple flat nozzles 433, forming a continuous water curtain. The operator puts the kitchen waste into the feeding hopper 420. The waste enters the barrel shell 210 along the connecting pipe seat 410 and falls on the upper surface of the turntable 223. During the crushing process, some fine waste or sewage will splash upwards and be intercepted by the annular water curtain, falling into the barrel shell 210 with the water flow, thus avoiding waste splashing at the source and improving the working environment.

[0043] Step 3: Start the drive motor 222. The drive motor 222 drives the turntable 223 to rotate at high speed. The crushing blade 224 on the upper surface of the turntable 223 performs primary crushing on the kitchen waste falling on the turntable 223. As the turntable 223 rotates, the crushed small pieces of waste move towards the edge of the turntable 223 under the action of centrifugal force and enter the side leakage gap 215 between the turntable 223 and the inner wall of the barrel shell 210. During the process of the waste passing through the side leakage gap 215, the side cutting blade 226 on the outer edge of the turntable 223 rotates synchronously to perform secondary crushing on the waste, further refining the waste and preparing it for subsequent grinding, while preventing large particles of waste from clogging the side leakage gap 215.

[0044] Step 4: The shredded waste particles fall through the side leakage seam 215 into the grinding chamber 214 between the upper grinding disc 225 and the lower grinding disc 235. Since the turntable 223 is fixedly connected to the upper grinding disc 225, the rotation of the turntable 223 drives the upper grinding disc 225 to rotate synchronously, while the lower grinding disc 235 remains stationary. Therefore, the upper grinding disc 225 and the lower grinding disc 235 rotate relative to each other, finely grinding the waste particles that fall into the grinding chamber 214. Depending on the type and hardness of the waste, the upper telescopic end of the double-headed electric telescopic rod 232 can be extended or retracted to drive the connecting arm 233, the top column 234 and the lower grinding disc 235 to move up and down, adjusting the gap of the grinding chamber 214. The ground waste forms a uniform slurry, which is convenient for subsequent solid-liquid separation.

[0045] Step 5: The ground waste slurry is filtered through the filter screen 213 inside the slag outlet 212. The filter screen 213 intercepts large particles of impurities that are not fully ground, preventing blockage of the guide pipe 320. The slurry enters the guide pipe 320 and is guided by the guide pipe 320 to flow into the hopper head 311 and then into the filter cylinder 312 along the inner wall of the hopper head 311. The liquid in the slurry, including water and grease, passes through the mesh and enters the annular chamber between the outer shell 330 and the filter cylinder 312, achieving preliminary solid-liquid separation. The solid organic matter of the slag is intercepted in the filter cylinder 312 and gradually accumulates.

[0046] During this process, the water supply hood 400 continuously supplies water. The water flow not only prevents splashing but also drives the flow of the ground slurry, preventing slurry residue in the barrel shell 210, the guide pipe 320, and the filter cartridge 312.

[0047] Step 6: When the slag in the filter cylinder 312 reaches the preset height, turn off the external water supply equipment, stop adding water, and start the double-headed electric telescopic rod 232. Control its lower telescopic end to extend downwards, driving the pressure plate 236 to move downwards and enter the filter cylinder 312. The pressure plate 236 continues to move downwards until it contacts the slag in the filter cylinder 312 and applies pressure, squeezing the slag between the pressure plate 236 and the material support plate 530. Under pressure, the residual water in the slag is further squeezed out, and the squeezed-out water passes through the filter cylinder 312 into the outer casing 330, achieving deep dewatering of the slag.

[0048] After extrusion is completed, the lower end of the double-headed electric telescopic rod 232 is retracted upward, causing the pressure plate 236 to move upward, disengage from the filter cylinder 312, and return to the initial position.

[0049] Step 7: The oily liquid collected inside the outer casing 330 flows into the pipe through the liquid outlet at the bottom and into the oil-water separator 600. The oil-water separator 600 separates the water phase and oil phase in the liquid. The oil has a lower density than water and floats on the surface of the liquid. It is collected through the oil outlet of the oil-water separator 600 and used for industrial recycling and reuse, such as in the production of biodiesel. The water phase is discharged through the water outlet and can be further filtered and recycled, such as for the water supply of the water filling hood 400, thus realizing the recycling of water resources. Step 8: After the extrusion and dewatering are completed, control the single-head electric telescopic rod 520 to retract downwards, driving the material support plate 530 to move downwards and disengage from the lower opening of the filter cylinder 312. Then, start the electric screw slide 510 to move the single-head electric telescopic rod 520, the material support plate 530, and the dewatered slag horizontally out of the filter cylinder 312 and reach the unloading position. The operator can clean and recycle the dewatered slag on the material support plate 530. After the slag is cleaned, control the electric screw slide 510 to drive the single-head electric telescopic rod 520 and the material support plate 530 back to the initial position. Then, control the single-head electric telescopic rod 520 to extend, driving the material support plate 530 to rise and fit against the lower opening of the filter cylinder 312, completing the equipment reset and preparing for the next round of waste treatment.
