TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen waste treatment, in particular to a three-phase slurry residue receiving device. BACKGROUND

[0002] Three-phase slurry residue generally refers to a mixture of solid particles, liquid and gas formed in certain industrial processes, especially in processes involving solid-liquid separation or gas-liquid-solid three-phase separation. In the context of kitchen waste treatment, three-phase slurry residue refers to solid residues obtained after three-phase separation treatment. Three-phase separation technology can effectively separate oil, water and solid substances in kitchen waste, and the solid residues, i.e. three-phase slurry residue, may contain food residues, small organic and inorganic particles, etc.

[0003] After the three-phase slurry residue is output from the three-phase centrifuge, it needs to be continuously transported to the next processing link to avoid stagnation and accumulation of the material during transportation. The existing conveying device is unstable, has a large pressure on the subsequent conveyor and processing equipment, and shortens the service life of the entire processing system. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings Figs. 1-2 The present application is further described in detail.

[0018] Example 1 of the present application discloses a three-phase slurry disposal device, or a disposal device.

[0019] Refer to Fig. 1The three-phase slurry residue receiving device comprises a feeding hopper 1 and a conveying mechanism, which includes at least two spiral conveyors arranged one above the other. The spiral conveyor comprises a horizontal conveying pipe 2, a rotary drive device 3, and a spiral body 4. The upper side wall of the horizontal conveying pipe 2 is provided with a feeding port 5, and the left end of the horizontal conveying pipe 2 is provided with a discharging port 6. The right end of the horizontal conveying pipe 2 is provided with the rotary drive device 3, which is connected to the spiral body 4. The spiral body 4 is arranged inside the horizontal conveying pipe 2. The feeding port 5 of the uppermost spiral conveyor is connected to the feeding hopper 1, and the discharging port 6 of the upper spiral conveyor is connected to the feeding port 5 of the lower spiral conveyor through an elbow pipe 7.

[0020] The working principle of the three-phase slurry residue receiving device will be explained below in conjunction with the use scenario:

[0021] Material input: The material first enters the conveying system through the feeding hopper 1. The feeding hopper 1 is designed to receive and temporarily store the three-phase slurry residue to be conveyed, providing a stable material source for the conveying process. The feeding hopper 1 can be connected to the residue phase output port of the three-phase centrifuge.

[0022] Initial conveying: The uppermost spiral conveyor receives the material from the feeding hopper 1. The feeding hopper 1 is directly connected to the feeding port 5 of the uppermost spiral conveyor, ensuring smooth entry of the material into the horizontal conveying pipe 2.

[0023] Spiral propulsion: The rotary drive device 3 drives the spiral body 4 to rotate through a power source such as an electric motor. The spiral body 4 is designed to push the material along the axial direction of the horizontal conveying pipe 2 to the left end when it rotates.

[0024] Material conveying: The material is pushed by the spiral body 4 and moves forward along the inside of the horizontal conveying pipe 2 until it reaches the left end of the horizontal conveying pipe 2, i.e. the discharging port 6.

[0025] Continuous conveying: The discharging port 6 of the upper spiral conveyor is connected to the feeding port 5 of the lower spiral conveyor through the elbow pipe 7. The design of the elbow pipe 7 allows the material to transition between different spiral conveyors, achieving continuous conveying. The discharging port 6 of the upper spiral conveyor can be designed as a cone to make the material more concentrated for conveying.

[0026] Multi-level conveying: With continuous conveying of the material between the spiral conveyors, multi-level material conveying can be achieved. Each level of spiral conveyor can adjust its rotation speed as needed to adapt to the material characteristics and conveying requirements.

[0027] Material output: The material is finally discharged through the discharging port of the lowermost spiral conveyor, completing the entire conveying process.

[0028] The design of this conveying device allows it to adapt to three-phase slurries with different characteristics, including viscosity and particle size. By adjusting the rotation speed of the screw conveyor and the connection method of the bend 7, it can flexibly adapt to different production needs. The entire conveying process takes place within a closed conveying pipe, reducing the possibility of material exposure to the environment, improving operational safety, and reducing environmental pollution.

[0029] Example 2, as shown in the attached document Fig. 2 As shown, based on Embodiment 1, the transverse conveying pipe 2 is equipped with a filter pipe 8. The filter pipe 8 has uniformly distributed filter holes 9, the size and distribution of which are designed to allow liquids or smaller particles to pass through while intercepting larger solid particles. A collecting pipe 10 is fitted over the filter pipe 8, with both ends of the collecting pipe 10 sealed and fixed to the transverse conveying pipe 2 to ensure that the filtrate does not leak into the external environment. The filter pipe 8 and the collecting pipe 10 are fitted with a clearance fit to form a sealed space, allowing the filtrate to flow within it. When the three-phase slurry passes through the filter pipe 8, solid particles are intercepted by the filter holes 9, while the liquid portion flows into the collecting pipe 10 through the filter holes 9. A filtrate outlet 11 is provided at the bottom of the collecting pipe 10. The filtrate outlet 11 is used to collect the liquid flowing into the collecting pipe 10 through the filter holes 9. By separating solids and liquids, this device can improve resource utilization. The filtrate outlet 11 can be connected to other processing systems or storage containers for further processing or recycling of the filtrate.

[0030] The filter tube 8 is rotatably connected to the transverse conveying pipe 2, allowing the filter tube to rotate as material passes through. This dynamic filtration reduces material blockage during the filtration process and improves filtration efficiency. A roller drive mechanism 12 is provided between the top of the collecting pipe 10 and the filter tube 8, which drives the rotation of the filter tube 8. The roller drive mechanism 12 can employ a synchronous belt mechanism and a gear transmission mechanism, which can be easily connected to the control system to achieve precise control of the rotation speed and direction of the filter tube 8. This arrangement ensures smooth and controllable rotation of the filter tube 8. The rotation of the filter tube 8 facilitates the movement of material on the filter surface, reduces material accumulation in the filter holes 9 at the bottom, and improves the overall processing capacity of the conveying device.

[0031] The top of the collection pipe 10 is rotatably mounted with a roller 13, which is in contact with the filter pipe 8. The surface of the roller 13 is provided with protruding slag-removing teeth 14, which are in concave-convex cooperation with the filter holes 9, so that the slag-removing teeth can effectively insert into the filter holes 9 during rotation to clean the material that may block the holes. Since the roller 13 continuously rotates following the filter pipe 8, the inner wall of the filter pipe 8 is continuously cleaned, reducing the decrease of filtering efficiency caused by material accumulation. By cleaning the filter pipe 8, solid particles are prevented from re-mixing into the filtered material, maintaining the purity of the filtered material. The need for clogging and maintenance is reduced, and the reliability and stability of the entire conveying device are improved.

[0032] The top of the collection pipe 10 is provided with a negative pressure interface 15 for connecting a negative pressure exhaust system. The negative pressure interface 15 is connected to the negative pressure exhaust system, which can reduce the pressure inside the collection pipe 10, thereby facilitating the filtered liquid to flow into the collection pipe 10 through the filter holes 9 of the filter pipe 8 more quickly. In some processes, it may be necessary to reduce the humidity of the material. The negative pressure system can assist the drying process by sucking away part of the moisture. If the three-phase slurry releases odors or volatile substances during processing, the negative pressure system can control the emission of these substances, reducing the impact on the working environment. Of course, the negative pressure interface 15 can also be connected to other different functional systems according to the needs of the actual process, becoming a blowing or rinsing interface.

[0033] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
