Technical Field

[0001] This invention relates to the technical field of waste treatment, and in particular to a device and process for treating kitchen waste in high-altitude areas. Background Technology

[0002] In daily life, a large amount of kitchen waste is often generated. In the process of aerobic composting of kitchen waste, it is necessary to first separate the oil and water in the waste.

[0003] In existing technologies, oil-water mixtures are typically separated from solid kitchen waste by draining.

[0004] However, in high-altitude areas, the temperature difference between day and night is large, and some oil-water mixtures may solidify or even freeze. Simply draining the water is not enough to effectively separate the oil-water mixture from the kitchen waste. Some of the oil-water mixture will enter the next process along with the solid kitchen waste, affecting the processing efficiency of subsequent aerobic composting. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a high-altitude kitchen waste treatment device and process, the purpose of which is to improve the oil-water separation efficiency of kitchen waste in high-altitude areas.

[0010] Furthermore, the actuating assembly includes: a first rotating roller rotatably mounted on the regulating tank; a pusher plate mounted on the first rotating roller along the width direction of the waterway; and a second drive motor for driving the first rotating roller to rotate, thereby driving the pusher plate to push the surface of the treatment liquid in a fixed direction.

[0011] Furthermore, the oil absorption assembly includes: a second rotating roller, which is a hollow filter cartridge, rotatably mounted on the equalization tank along the width direction of the water channel; an oil absorption layer, wrapped around the second rotating roller and capable of sinking to a fixed depth in the treatment liquid; a third drive motor for driving the second rotating roller to rotate; a squeezing roller, disposed on one side of the second rotating roller, for squeezing the oil absorption layer; a second receiving trough, passing through the second rotating roller and mounted on the treatment tank, for receiving the grease squeezed off from the oil absorption layer; and a transfer pump for transferring the grease in the second receiving trough.

[0013] Furthermore, the device also includes: an electric heating component disposed in the regulating tank for heating the treatment liquid; and a second delivery pump capable of delivering the treatment liquid to the medium channel through delivery pipes, thereby using the treatment liquid as a heat transfer medium.

[0014] Furthermore, both the regulating pool and the guide blocks are circular, with the guide blocks installed inside the regulating pool to form a ring-shaped waterway within the regulating pool.

[0015] Furthermore, both the regulating pool and the guide blocks are rectangular, with the guide blocks installed inside the regulating pool to form rectangular waterways within the regulating pool.

[0016] A process for treating kitchen waste in high-altitude areas includes the following steps: S1, feeding the kitchen waste to be treated into the cylinder; S2, starting the first drive motor to rotate, driving the spiral blades to rotate and continuously pushing the kitchen waste along the axial direction; S3, continuously feeding a heat transfer medium into the medium channel to raise the temperature of the kitchen waste in the cylinder and melt the condensed oil-water mixture; S4, transferring the solid kitchen waste pushed out of the cylinder for composting; and transferring the oil-water mixture flowing out of the filter holes for oil-water separation.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] Example 1

[0029] Reference Figure 1 As shown, this embodiment of the invention provides a plateau kitchen waste treatment device, comprising: a cylindrical body 1, horizontally installed for feeding kitchen waste; a rotating shaft 11, made of heat transfer material, rotatably disposed inside the cylindrical body 1; a first drive motor 13, connected to the rotating shaft 11 for driving the rotating shaft 11 to rotate; a spiral blade 12, mounted on the rotating shaft 11 for pushing the kitchen waste along the axial direction of the rotating shaft 11; a medium channel, opened inside the rotating shaft 11 for the flow of heat transfer medium, for providing heat to the rotating shaft 11 and increasing the temperature of the rotating shaft 11, thereby melting the condensed oil-water mixture; a filter hole 14, opened at the bottom of the cylindrical body 1 for the oil-water mixture to flow out; and an oil-water separation mechanism for receiving the oil-water mixture and performing oil-water separation.

[0030] In this invention, a rotating shaft 11 and a spiral blade 12 are provided in the cylinder 1, which can push the kitchen waste put into the cylinder 1 along the axial direction for continuous feeding; it can also tumble the kitchen waste along the circumferential direction and keep the kitchen waste in continuous contact with the rotating shaft 11.

[0031] In this invention, a medium channel is also provided inside the rotating shaft 11, and the rotating shaft 11 is made of heat transfer material. By continuously sending high-temperature heat transfer material into the medium channel, the temperature of the rotating shaft 11 can be increased. When the circumferentially tumbling kitchen waste comes into contact with the rotating shaft 11, the oil-water mixture condensed in the kitchen waste can be melted. Under the action of gravity, the oil-water mixture falls out of the cylinder 1 through the filter hole 14, and the solid waste is pushed out of the cylinder 1 along the axial direction under the action of the spiral blades 12.

[0032] By using this invention, kitchen waste can be continuously heated and transported, ensuring continuous feeding while heating the kitchen waste to separate the condensed oil-water mixture. This effectively improves the oil-water separation rate of kitchen waste in plateau areas and enhances the subsequent aerobic composting efficiency of kitchen waste.

[0033] It is worth mentioning that the first drive motor 13 is connected to the rotating shaft 11 via gear transmission.

[0034] It is worth mentioning that the rotating shaft 11 can be made of thermally conductive metal materials such as copper, aluminum, and iron; in order to further improve the heat transfer efficiency, the spiral blades 12 can also be made of thermally conductive metal materials.

[0035] It is worth mentioning that the device also includes: a conveying pipe 15 for conveying the heat transfer medium; and a dynamic sealing component for rotatably installing one end of the conveying pipe 15 into the medium channel.

[0036] It is understood that dynamic sealing technology is a well-known technology in the field, and those skilled in the art can complete the installation of the conveying pipe 15 rotatably in the medium channel using dynamic sealing components using well-known technologies in the field; specifically, dynamic sealing methods such as oil seals, labyrinth seals, and mechanical seals can be selected.

[0037] Example 2

[0038] Reference Figure 2 As shown, in this embodiment, the oil-water separation mechanism includes: a first receiving tank 21, disposed below the filter holes 14, for receiving an oil-water mixture; a treatment tank 22, which stores a treatment liquid at a fixed liquid level, and the density of the treatment liquid is higher than that of the grease; a first delivery pump 23, for transporting the oil-water mixture in the first receiving tank 21 into the treatment tank 22; a guide block 24, disposed in the treatment tank 22, protruding from the surface at a fixed height, thereby forming a circulating waterway in the treatment tank 22; a stirring component 3, disposed on the waterway, for stirring the liquid surface of the treatment liquid to circulate along the waterway; and an oil suction component 4, disposed on the waterway, for suctioning away the grease floating on the liquid surface of the treatment liquid.

[0039] The actuating assembly 3 includes: a first rotating roller 31, which is rotatably mounted on the regulating tank; a push plate 32, which is mounted on the first rotating roller 31 along the width direction of the waterway; and a second drive motor 33, which drives the first rotating roller 31 to rotate, thereby driving the push plate 32 to push the surface of the treatment liquid in a fixed direction.

[0040] Reference Figure 3 , Figure 4 and Figure 5As shown, the oil absorption assembly 4 includes: a second rotating roller 41, which is a hollow filter cylinder, rotatably mounted on the regulating tank along the width direction of the water channel; an oil absorption layer 42, which wraps around the second rotating roller 41 and can sink to a fixed depth in the treatment liquid; a third drive motor 43, used to drive the second rotating roller 41 to rotate; a squeezing roller 44, which is disposed on one side of the second rotating roller 41 and used to squeeze the oil absorption layer 42; a second receiving trough 45, which passes through the second rotating roller 41 and is mounted on the treatment tank 22, used to receive the grease squeezed off from the oil absorption layer 42; and a transfer pump 46, used to transfer the grease in the second receiving trough 45.

[0041] In actual operation, the oil-water mixture in the first receiving tank 21 is input into the treatment liquid by the first delivery pump 23. The density of the treatment liquid is higher than that of the grease, and the grease floats on the surface of the treatment liquid under the action of gravity.

[0042] The first roller 31 is driven to rotate by the second drive motor 33, which drives the push plate 32 to enter / exit the treatment liquid, thereby pushing the liquid surface of the treatment liquid to move along the waterway distribution path. In this embodiment, by setting the agitator 3, the grease on the liquid surface can be driven to move towards the oil suction assembly 4, and the grease floating on the liquid surface of the treatment liquid is continuously sent to the oil suction assembly 4 to continuously transport the grease floating on the liquid surface.

[0043] The second roller 41 is driven to rotate by the third drive motor 43, and the oil-absorbing layer 42 is used to suck away the grease floating on the liquid surface. The second roller 41 is a hollow filter cylinder. By setting a squeezing roller 44 above the second roller 41, the oil-absorbing layer 42 can be squeezed to squeeze out the grease in the oil-absorbing layer 42. Under the action of gravity, the grease falls into the second roller 41. A second receiving groove 45 is set in the second roller 41. The grease falling into the second roller 41 falls into the second receiving groove 45, and the grease in the second receiving groove 45 is transferred by the transfer pump 46 and processed uniformly.

[0044] In this embodiment, by setting the oil suction component 4, the grease on the liquid surface can be continuously sucked away, the water in the oil-water mixture remains in the treatment tank 22, and the grease is partially transferred by the oil suction component 4; by setting the oil suction component 4 on the regulating tank, the oil-water separation operation can be completed automatically, improving the oil-water separation efficiency and achieving a high degree of automation.

[0045] In this embodiment, by setting the extrusion roller 44 to extrude grease toward the inside of the second roller 41, the extruded grease passes through the second roller 41 and falls into the second receiving groove 45; this can eliminate secondary contact between grease and oil-absorbing layer 42, improve the extrusion efficiency of grease in oil-absorbing layer 42, and ensure the continuous absorption efficiency of grease.

[0046] Specifically, the second roller 41 is rotatably mounted on the treatment tank 22 via bearings, and the third drive motor 43 is connected to the second roller 41 via a transmission rod. The transmission rod is connected to the output shaft of the third drive motor 43 and the second roller 41 via gears.

[0047] Along the axial direction of the second roller 41, a number of protrusions 47 are provided on the second roller 41; between any two protrusions 47, a tooth 48 is provided on the extrusion roller 44; as the second roller 41 rotates, the tooth 48 can be driven to enter between the two protrusions 47, and the oil-absorbing layer 42 is squeezed toward the side wall of the protrusion 47, thereby improving the extrusion efficiency of the grease.

[0048] The device also includes an electric heating component, which is installed in the conditioning tank to heat the treatment liquid. By heating the treatment liquid, the molecular motion rate in the treatment liquid can be increased, which helps the oil to float to the surface of the liquid quickly and speeds up the oil-water separation efficiency.

[0049] Understandably, the electric heating component includes several resistance wires installed at the bottom of the regulating tank. The resistance wires are electrically connected to the power source via wires, and the treatment liquid can be heated by supplying current to the resistance wires.

[0050] Reference Figure 6 As shown, the device also includes a second transfer pump 52, which can transfer the treatment liquid to the medium channel through the transfer pipe 15, and the treatment liquid serves as a heat transfer medium; it is understood that the treatment liquid can be either water or oil.

[0051] Example 3

[0052] Reference Figure 7 As shown, in this embodiment, both the regulating pool and the guide block 24 are circular. The guide block 24 is installed inside the regulating pool, thereby forming a ring-shaped waterway within the regulating pool.

[0054] Reference Figure 8 As shown, in this embodiment, both the regulating pool and the guide block 24 are rectangular. The guide block 24 is installed inside the regulating pool, thereby forming a rectangular waterway within the regulating pool.
