Description

Technical Field

[0001] The invention relates to the technical field of restaurant and kitchen waste treatment, and in particular to a novel restaurant and kitchen waste treatment device. Background Art

[0002] Kitchen waste is divided into catering waste and kitchen waste. The former is produced from restaurants, canteens, etc., while the latter comes from residents' daily life. Its main characteristics are rich organic matter content, high water content, and easy to rot. Its properties and odor have a bad impact on environmental hygiene and are easy to breed pathogenic microorganisms, mycotoxins and other harmful substances.

[0003] With the increasing requirements for environmental protection, the effective treatment of food waste has become extremely important. The food waste treatment equipment currently on the market has shortcomings in terms of how the oil-water mixture can flow stably into the oil-water separator. In the prior art, the oil-water mixture after the slag-liquid separation flows directly into the oil-water separator without a flow-limiting structure, which can easily affect the separated oil layer in the oil-water separator, and further affect the working effect of the oil-water separator. Therefore, in order to ensure the stable operation of the oil-water separator, the prior art mostly uses a multi-mesh plate and sets a baffle at the liquid outlet of the slag-liquid separation equipment. The above-mentioned prior art has the problem that when blockage occurs, it cannot be quickly cleaned, which affects the flow-limiting effect, and it is also impossible to clean the blockage without stopping the machine and maintaining the flow-limiting function.

[0004] At the same time, the existing oil-water separation equipment is often equipped with a drainage chamber, which holds the separated water to a certain capacity and then discharges it. This technical solution has the disadvantages of low efficiency and large equipment volume, and the sediments deposited at the bottom of the drainage chamber and the oil-water separation chamber are difficult to be discharged uniformly;

[0005] With the increasing environmental protection requirements, the effective treatment of restaurant kitchen waste has become extremely important. The restaurant kitchen waste treatment equipment on the market currently has deficiencies in solid-liquid separation, oil-water separation, grease treatment, liquid level control, overflow sewage discharge, etc., and a more efficient and reliable restaurant kitchen waste treatment equipment is needed.

The constant temperature module 112 is arranged at the oil collection layer 14, which can effectively prevent the grease from condensing and emulsifying, and can improve the purity of the oil under the action of heat energy.

[0053] Reference Figure 1 and Figure 2 As shown, the solid-liquid separation device 2 includes a separation module and a flow limiting module 22.

A working chamber 211 is provided in the separation working box 21, and the working chamber 211 is connected to the top of the separation working box 21 as a feed inlet.

[0054] In this embodiment, the working chamber 211 is tilted, the higher end of the working chamber 211 is arranged at the slag discharge port (not shown in the figure), and the lower end of the working chamber 211 is provided with a liquid outlet 212, which is in communication with the outer side of the separation working box 21. The power module 24 is arranged on the outer side surface of the separation working box 21 adjacent to the lower end of the working chamber 211.

[0055] Furthermore, a screen 213 is fixedly provided in the working chamber 211, and a pressing chamber 214 is formed between the screen 213 and the feed port. The rotating component 23 is obliquely rotated and arranged in the pressing chamber 214, one end of the rotating component 23 is rotationally connected to a higher end in the working chamber 211, and the other end thereof passes through a lower end in the working chamber 211 and is transmission-connected to the power module 24.

[0056] In this embodiment, the rotating component 23 is a variable pitch screw.

[0057] The power module 24 of this embodiment is a common and commonly used driving structure for driving circumferential rotation, such as a motor driving a sprocket chain.

[0058] A liquid discharge channel 215 is formed between the bottom of the screen 213 , the bottom of the working chamber 211 , and the liquid outlet 212 .

[0059] A liquid guide plate 26 is fixedly arranged at the liquid outlet 212, and a higher end of the liquid guide plate 26 is fixedly connected to the bottom end of the liquid outlet 212. In this embodiment, the liquid guide plate 26 guides the liquid flowing out of the liquid outlet 212 downward. The flow limiting module 22 is arranged between the liquid outlet 212 and the liquid guide plate 26.

[0060] Reference Figure 3 As shown, the flow limiting module 22 includes a flow limiting cover 221, a first flip plate 222, a second flip plate 223 and a swing arm 224. The bottom and outer side of the flow limiting cover 221 are respectively fixedly connected to the top of the liquid guide plate 26 and the outer side of the separation working box 21. The outer wheel of the flow limiting cover 221 in this embodiment is N-shaped.

[0061] An overflow plate 225 is disposed in the flow limiting cover 221 , and the top and both sides of the overflow plate 225 are fixedly connected to the top and both sides of the flow limiting cover 221 , respectively.

[0062] Furthermore, a flood overflow port 225 - 1 is provided on the overflow plate 225 , and the flood overflow port 225 - 1 is in communication with the liquid outlet 212 .

[0063] Recombination Figure 4 As described above, a flow limiting working position is formed between the bottom of the overflow plate 225 and the top of the liquid guide plate 26. The first flip plate 222 and the second flip plate 223 are movably arranged in the flow limiting working position.

[0064] The first flip plate 222 is flippably arranged in the current limiting working position, and the outer side surface of the first flip plate 222 is hinged to the outer side surface of the overflow plate 225 through the hinge module 226. In the initial state, the first flip plate 222 is flush with the overflow plate 225, so that a current limiting channel 27 is formed between the bottom of the first flip plate 222 and the top of the liquid guide plate 26. One end of the swing arm 224 is fixedly connected to the outer side surface of the first flip plate 222, and the other end of the swing arm 224 is connected to the driving device (not shown in the figure).

[0065] The driving device in this embodiment is any one of a pneumatic cylinder, an oil cylinder, and an electric pole.

[0066] The second flip plate 223 is fixedly arranged at an angle on the inner side of the first flip plate 222. Specifically, the second flip plate 223 is provided with a vertical section 223-1 and an oblique section 223-2. The vertical section 223-1 is fixedly arranged on the inner side of the first flip plate 222. Specifically, when the first flip plate 222 is flush with the overflow plate 225, the oblique section 223-2 is obliquely arranged from the top of the vertical section 223-1 toward the liquid outlet 212, and the higher end of the second flip plate 223 faces the upper half of the liquid outlet 212.

[0067] In this embodiment, the higher end of the second flip plate 223 is located outside the liquid outlet 212 to ensure that when the second flip plate 223 flips downward, its higher end does not interfere with the liquid guide plate 26 to cause rotation failure.

[0068] The hinge module 226 of this embodiment is preferably a torsion spring hinge.

[0069] Furthermore, an overflow position 227 is formed between the overflow plate 225 , the liquid outlet 212 , and the oblique section 223 - 2 , and the overflow port is in conduction with the overflow position 227 .

[0070] Reference Figure 1-Figure 5 As shown, when the device is working, the solid-liquid mixture enters the pressing chamber 214 from the feed port, the power module 24 drives the rotating component 23 to rotate to squeeze the solid-liquid mixture, and the liquid filtered by the screen 213 flows to the liquid outlet 212 through the drainage channel 215, and the flow limiting channel 27 is retained outward to the oil-water separation device 3, and the first flip plate 222 plays a flow limiting role, specifically, the liquid flows into the oil-water separation device 3 at a stable flow rate to ensure the stability of its working effect;

[0071] Some residues are inevitably mixed in the liquid. After long-term use, the residues will accumulate between the first flip plate 222 and the liquid guide plate 26, causing the flow limiting channel 27 to fail. At this time, the liquid flows into the overflow position 227 and flows out from the overflow port, eliminating the flooding caused by blockage.

[0072] At the same time, the driving device drives the swing arm 224 to move upward, thereby driving the first flip plate 222 to flip upward 90 degrees. During the process of the first flip plate 222 flipping upward, the second flip plate 223 is driven to flip downward. During the process of the second flip plate 223 flipping downward, the oblique section 223-2 scrapes the residue downward.

[0073] At the same time, a gap is set between the inclined section 223 - 2 and the top of the liquid guide plate 26 to maintain the flow limiting function.

[0074] In this embodiment, the device realizes the flow limiting function by setting the first flip plate 222. At the same time, the first flow limiting plate can be flipped to change the position of the second flip plate 223 to remove the residue blocking the installation position. Compared with the prior art, this device has a self-cleaning function; further, by setting the overflow position 227 and the overflow port 225-1, the normal operation of the device is guaranteed when the flow limiting module 22 fails.

[0075] The flow limiting, residue removal and flood overflow structures of this embodiment are simple and reasonable, with low production and maintenance costs and stable and reliable effects.

[0076] Reference Figure 1 , Figure 6 As shown, the outer contour section of the oil spiller 4 is C-shaped, and the opening of the outer contour of the oil spiller 4 serves as an oil-passing notch 41. A connecting through hole that is in communication with the first working chamber 11 is provided on the outer side wall of the working box 1, and the oil spiller 4 is rotatably provided on the connecting through hole, and one end of the oil spiller 4 is provided outside the working box 1 through the connecting through hole. The rotating connection structure between the oil spiller 4 and the connecting through hole is a well-known technology and will not be described here. Furthermore, an airtight element (such as a sealing ring, etc.) is provided between the outer periphery of the oil spiller 4 and the connecting through hole to prevent oil leakage.

[0077] The end of the oil overflow device 4 outside the working box 1 is provided with an oil discharge channel 42, and a collecting bucket (not shown) is provided below the end of the oil discharge channel 42. The oil gap 41 is connected to the oil discharge channel 42, and the oil in the oil collecting layer 14 enters the oil discharge channel 42 through the oil gap 41 and is discharged outward.

[0078] The outer periphery of the oil spiller 4 outside the working box 1 is provided with a rotating handle 43, and one end of the rotating handle 43 is fixedly connected to the outer periphery of the oil spiller 4. A pre-positioning plate 15 is provided between the rotating handle 43 and the outer side wall of the working box 1, and the pre-positioning plate 15 is fixedly provided on the outer side wall of the working box 1. The pre-positioning plate 15 is provided with a plurality of pre-positioning holes 151, and the plurality of pre-positioning holes 151 are arranged in an arc array with the connecting through hole as the center.

[0079] The rotating handle 43 is provided with an inserting through hole 431 , and the inserting through hole 431 is inserted into the pre-positioning hole 151 via a pin, thereby limiting the circumferential movement freedom of the oil spiller 4 during operation.

[0080] During operation, the oil-water mixture flows out from the flow limiting channel 27 into the first working room 11, and is separated into oil and water by flowing upward and downward respectively under the action of the oil-water separator 33. The oil at the separation point floats in the oil collecting layer 14, and the separated water flows into the second working room 12.

[0081] According to production needs, the rotating handle 43 is turned to drive the oil overflow device 4 to rotate with the connecting through hole as the center, the plug-in through hole 431 on the rotating handle 43 is aligned with the pre-positioning holes 151 at different positions on the pre-positioning plate 15 and a pin is inserted, and the rotation angle of the oil overflow device 4 is quickly set through the pre-positioning hole 151, and then the direction of the oil notch 41 is adjusted to control the height of the oil collecting layer 14.

[0082] The present embodiment realizes the control of the height of the oil layer by setting a reversible oil overflow device 4. Compared with the existing technology (such as scraping oil, gravity flow) that needs to rely on the thickness of the oil layer to drain the oil, the oil overflow device 4 in the present embodiment can adjust the accumulated height of the oil layer and drain the oil in combination with the working condition of the oil-water separator 33, while saving the manufacturing cost of the equipment.

On the contrary, the plugging head 63 is inserted into the drain port 121 to close the liquid path between the second working room 12 and the drain pipe 122.

In this embodiment, the limit portion 532-1 is formed integrally with the detection movable rod 532. The limit portion 532-1 is located between the measuring tube positive sleeve 531 and the detection module 52.

[0095] Furthermore, the outer diameter of the limit portion 532-1 is larger than the diameter of the tube positive through hole 531-1. When the bottom of the limit portion 532-1 is in contact with the top of the measuring tube positive sleeve 531, the downward displacement of the detection movable rod 532 is limited to prevent the device from failing.

[0096] The floating component 533 is connected to the other end of the detection movable rod 532 , and the floating component 533 is located below the measuring tube main sleeve 531 .

[0097] Furthermore, a second threaded portion is disposed on the outer periphery of the other end of the detection movable rod 532, and an adjusting portion 533-1 is disposed on the top of the floating component 533. In this embodiment, the adjusting portion 533-1 is formed integrally with the floating component 533.

[0098] The adjusting portion 533 - 1 is provided with a threaded hole from the top downward, and the threaded hole is threadedly connected with the second threaded portion.

[0099] Furthermore, the adjusting portion 533 - 1 is provided with an outer hexagon 533 - 11 . When in use, a tool is applied to the outer hexagon 533 - 11 and rotated, thereby adjusting the relative position of the adjusting portion 533 - 1 on the second threaded portion to fine-tune the setting height of the floating component 533 .

[0100] Furthermore, the measuring tube sleeve 531 is T-shaped in the vertical section, and the outer periphery of the vertical section of the measuring tube sleeve 531 is provided with a first threaded portion 531-2, which is threadedly connected to the mounting through hole 511-1. By rotating the outer periphery of the horizontal section of the measuring tube sleeve 531 to make it rise and fall on the mounting through hole 511-1, the setting height of the floating component 533 is adjusted.

[0101] Reference Figure 1 As shown, the outer contour of the overflow pipe 7 of this embodiment is N-shaped, and the end of the vertical section on one side of the overflow pipe 7 is arranged in the sedimentation layer 13, and the end of the vertical section on the other side passes through the working box 1 and is fixed on the drain pipe 122 to make the sedimentation layer 13 and the drain pipe 122 conductive.

[0102] Furthermore, the top of the bend of the overflow pipe 7 is higher than the oil collecting layer 14 .

[0103] Furthermore, a vent pipe 71 is provided at the top of the bend of the overflow pipe 7 to balance the air pressure between the overflow pipe 7 and the drain pipe 122 to prevent the occurrence of a siphon phenomenon.

[0104] During operation, when the liquid level in the working box 1 exceeds the bend of the overflow pipe 7, a pressure difference is formed between the side of the overflow pipe 7 connected to the sedimentation layer 13 and the other side of the overflow pipe 7 connected to the drain pipe 122, so as to discharge the liquid exceeding the constant liquid level height and the sediment at the bottom to the drain pipe 122.

[0105] Furthermore, an automatic water replenishing device 8 is also provided in the second working room 12. The automatic water replenishing device 8 includes a water replenishing pipe 81 and a solenoid valve 82. The water replenishing pipe 81 includes a water inlet section 811 and a water outlet section 812. The water outlet section 812 is fixedly provided in the second working room 12, and its opening extends to the sedimentation layer 13. The water inlet section 811 is fixedly provided on the side wall of the working box body 1, and the opening of the water inlet section 811 is located outside the working box body 1 for connecting to an external water source. A solenoid valve 82 is provided on the water inlet section 811 located outside the working box body 1, and the solenoid valve 82 is used to control the on-off of the liquid path between the water inlet section 811 and the water outlet section 812. The solenoid valve 82 is electrically connected to the detection circuit of the detection module 52.

[0106] Recombination Figure 1-9 As shown, during operation, the floating component 533 is arranged in the oil collecting layer 14. When the liquid level in the detected device rises, the floating component 533 is pushed upward, and the detection movable rod 532 is driven to slide along the tube positive through hole 531-1, so that the limit portion 532-1 is penetrated into the circular hole portion 523 to change the magnetic field distribution inside the annular sensing element 522 to cause a voltage change, and the voltage change is measured by the detection circuit and an electrical signal is output to control the closing action of the solenoid valve 82; when the liquid level in the working box 1 is lower than the preset position, the floating component 533 drops, and the detection circuit outputs an electrical signal to control the solenoid valve 82 to open, and the water inlet section 811 passes water to realize the automatic water supply and water replenishment function. Since the water inlet section 811 extends into the sedimentation layer 13, when supplying water, it can increase the fluidity of the sediment in the sedimentation layer 13, which helps the sediment to be discharged from the overflow pipe 7 to prevent blockage and drainage.

[0107] In this embodiment, the detection module cooperates with the liftable detection movable rod driven by the floating component to transmit a signal, thereby determining whether the liquid level in the detected device reaches the set position.

[0108] Compared with the liquid level detection device in the prior art, the electrical part of this device does not come into contact with the liquid (oil, liquid), avoiding the functional problems caused by the traditional liquid level sensor directly contacting or approaching the oil layer, or even being affected by the accumulation of oil smoke, thus realizing a separate detection device.

[0109] The overall installation of this embodiment is simple and can be directly installed on the existing detected equipment. In actual use, the device is simple, safe and reliable, which improves the user experience.

Any modifications made according to the spirit of the main technical solution of the present invention should be included in the protection scope of the present invention.
