Description

Technical Field

[0001] The invention belongs to the technical field of kitchen waste treatment, and particularly relates to a kitchen waste oil-water separation device. Background Art

[0002] Kitchen waste refers to waste materials generated in daily life that are easy to rot, spoil and stink; including discarded vegetable leaves, leftovers, leftover rice, fruit peels, egg shells, tea residues, bones, etc. Its main sources are family kitchens, restaurants, hotels, canteens, markets and other industries related to food processing. The main components of kitchen waste are large amounts of liquid oil and solid kitchen waste. Some of the oil is waste oil from frying, some is oil in soup, and some is oil discharged during washing. Kitchen waste should be provided to professional processing units for treatment. It is strictly prohibited to use waste edible oil and gutter oil as edible oil after processing. It is strictly prohibited to directly use kitchen waste to feed livestock, poultry and fish. It is strictly prohibited to use kitchen waste that has not been harmlessly treated to produce fertilizer.

[0003] At present, the preliminary treatment method of food waste is to separate the food residue into solid and liquid first. The solid-liquid separation is generally carried out by filtering with a filter net. The filtered liquid is left to stand to separate the oil and water, and then the separated oil and water are collected separately.

[0004] The prior art has the following deficiencies:

[0005] Since food residues themselves contain a large amount of oil and water, the static filtration method cannot separate the oil and water inside the food in a short period of time. Summary of the invention

[0006] In view of this, the present invention provides a kitchen waste oil-water separation device to solve the problem that the existing static filtration method cannot separate the oil and water in the food in a short time.

[0007] The technical solution adopted by the present invention is as follows:

[0008] A kitchen waste oil-water separation device comprises a separation box with a feed inlet on the top, a filter plate embedded in the separation box, the filter plate dividing the separation box into an upper solid-liquid separation chamber and a lower oil-water separation chamber; a rotating cylinder is provided on the top of the filter plate, the rotating cylinder is driven to rotate by a driving device, and a liquid outlet is provided on the side wall of the rotating cylinder; an oil outlet and a water outlet are respectively provided on the side wall and the top of the lower oil-water separation chamber, and the oil outlet and the water outlet are both provided with valves.

[0009] In this technical solution, it should be noted that the separation box is cylindrical, and its bottom is provided with supporting legs, the number of which is specifically four, and is made of steel. Its bottom can be fixed to the ground by bolts, and a sealing cover is provided on the top of the separation box (the sealing cover is hinged with the rotating drum, not shown in the figure), and the feed port can be provided on the sealing cover. There is a gap between the bottom of the rotating drum and the filter plate, and the two are concentric. In this solution, when it is necessary to process the kitchen waste, the waste is first put into the rotating drum through the feed port, and then the rotating drum is driven to rotate by the driving device. After the rotating drum rotates, the oil and water in the waste are thrown out by centrifugation, and the thrown out oil and water fall into the lower oil-water separation chamber through the small holes on the filter plate, and are left to stand in the lower oil-water separation chamber for a period of time until the oil and water are separated, and then the staff discharges the oil and water separately through the oil outlet and the water outlet to achieve the purpose of oil-water separation. In summary, in the present invention, the solid and liquid in the kitchen waste are separated by a centrifugal method, the separation efficiency is fast, and the oil and water contained in the waste itself can also be thrown out by the centrifugal method, making the separation more thorough. Secondly, the present invention integrates the solid-liquid separation device and the oil-water separation device, and the oil and water separated from the waste can fall into the lower oil-water separation chamber below for static separation.

[0010] Preferably, a plurality of solid discharge ports are provided on the side wall of the rotating drum, and a spring door is provided at the solid discharge port, and the spring door is hinged to the rotating drum through a rotating shaft; a linkage rod is provided at the bottom of the rotating shaft passing through the rotating drum, and the linkage rod is arranged along the diameter direction of the rotating shaft, and an annular groove is provided on the top of the filter plate, and an annular plate is connected to the annular groove through a one-way bearing, and a vertical rod is provided on the top of the annular plate, and the top of the vertical rod is higher than the top of the linkage rod.

[0011] In this technical solution, it should be noted that a spring door is a type of door classified according to the way the door is opened. A door equipped with a spring hinge will automatically close after being opened; a one-way bearing is a bearing that can rotate freely in one direction and is locked in the other direction. In the present scheme, the inner ring of the one-way bearing is interference connected with the outer side wall of the annular plate, and the outer ring of the one-way bearing is fixedly connected with the inner wall of the annular groove. The counterclockwise rotation direction of the annular plate is the direction in which the inner ring and the outer ring of the one-way bearing are locked, that is, the annular plate cannot rotate in the counterclockwise direction; the clockwise rotation direction of the annular plate is the direction in which the inner ring and the outer ring of the one-way bearing are movably connected, that is, the annular plate can rotate in the clockwise direction; in the present scheme, it is also necessary to further explain that after the centrifugal operation of the kitchen waste in the rotating drum is completed, the solid waste needs to be taken out and recycled. However, since the rotating drum has a certain depth, it is not convenient to recycle. Based on this, the present invention sets a one-way bearing, a spring door, a linkage rod, annular plate and a vertical rod. When the driving device drives the rotating drum to rotate clockwise, the rotating drum centrifuges the garbage. Since the outer ring and the inner ring of the one-way bearing are in an active state at this time, the linkage rod After contacting the vertical rod, the vertical rod has no limiting effect. Therefore, when the linkage rod rotates with the rotating drum, it will drive the vertical rod and the annular plate connected to the vertical rod to rotate clockwise after contacting the vertical rod, and the spring door is in a closed state to prevent the garbage in the centrifugal process from being thrown out. When the garbage is centrifuged, it is necessary to take out the garbage inside the rotating drum. At this time, the driving device is used to control the rotating drum to rotate counterclockwise. At this time, since the outer ring and the inner ring of the one-way bearing are in a locked state, after the linkage rod contacts the vertical rod, the vertical rod is in a fixed state and has a limiting effect. Therefore, when the linkage rod rotates with the rotating drum, after contacting the vertical rod, it will gradually rotate counterclockwise due to the obstruction of the vertical rod, thereby driving the rotating shaft to rotate counterclockwise. The counterclockwise rotation of the rotating shaft then drives the spring door to gradually open. At this time, the solid garbage in the rotating drum will be thrown into the separation box through centrifugal action, which is convenient for the staff to collect. To sum up, in the present invention, by providing the one-way bearing, spring door, linkage rod, annular plate and vertical rod, the solid waste in the rotating drum can be normally centrifuged when the rotating drum rotates clockwise. After the centrifugation of the solid waste is completed, the rotating drum can gradually open the spring door by rotating counterclockwise, so that the solids in the rotating drum can be automatically thrown out of the rotating drum through centrifugation, which is convenient for the staff to collect.

[0012] Preferably, a locking groove is provided on the top of the linkage rod, a locking rod which can be inserted into the locking groove is elastically connected to the bottom of the rotating cylinder, and a guide surface is obliquely provided on the side wall of the locking rod, and the guide surface cooperates with the linkage rod.

[0013] In this technical solution, it should be noted that when the rotating cylinder rotates counterclockwise, since the linkage rod will be offset from the vertical rod after a period of time, the spring door will automatically close due to its own elastic force. Based on this, the present invention is provided with a locking groove, a locking rod and a guide surface. After the linkage rod is rotated to a certain position through the obstruction of the vertical rod, it will contact the guide surface of the locking rod, and then squeeze the guide surface. The guide surface distributes the pressure vertically upward through its own inclined surface, so that the locking rod gradually moves upward, and in the process of the linkage rod rotating counterclockwise, the locking rod will be opposite to the locking groove on the linkage rod up and down. At this time, the locking rod is inserted into the locking groove through elastic force to limit the linkage rod, so that the spring door is always in an open state.

[0014] Preferably, during the process of inserting the locking rod into the locking groove, before the locking rod is inserted into the locking groove, the rotating cylinder rotates at a low speed, and after the locking rod is inserted into the locking groove, the rotating cylinder switches from the low speed rotation to the high speed rotation.

[0015] In this technical solution, it should be noted that after the locking rod rises to the top of the locking groove through the cooperation of the inclined surface and the linkage rod, if the rotation speed of the rotating drum is too fast at this time, the speed at which the locking rod is inserted into the locking groove will be much lower than the rotation speed of the locking groove, which will cause the locking rod to be unable to be smoothly inserted into the lock. Therefore, this solution sets a low-speed rotation mode and a high-speed rotation mode. The low-speed rotation mode facilitates the smooth insertion of the locking rod into the locking groove, and the high-speed rotation mode is used for the centrifugal effect of the solid. This solution can be implemented by providing a sensor in the locking groove. Before the locking rod contacts the locking groove, the rotating drum rotates at a low speed. After the locking rod is inserted into the locking groove, the sensor sends a sensing signal to the drive device, and the drive device drives the rotating drum to rotate at a high speed.

[0016] Preferably, an annular strip is provided on the top of the rotating cylinder, and the top of each locking rod slides through the rotating cylinder and is fixedly connected to the annular strip. The annular strip is connected to the rotating cylinder via a spring, and the spring is sleeved on the locking rod.

[0017] In this technical solution, it should be noted that after the solids are thrown out of the rotating drum, the spring door needs to be closed in order to carry out the next solid-liquid separation operation. Therefore, this solution is provided with a spring and an annular bar. When the spring door needs to be closed, the annular bar is pulled upward, so that all the locking rods are moved upward, so that the locking rods and the locking grooves are staggered up and down, and then the rotating drum is rotated a certain angle so that the locking rods and the locking grooves are staggered left and right, so that the limiting effect of the locking rods and the locking grooves can be released, and the spring door will be reset by its own elastic force.

[0018] Preferably, an opening and closing door is hinged on the side wall of the upper solid-liquid separation chamber.

[0019] In this technical solution, it should be noted that after the solids are thrown out of the rotating drum, the staff can open the door and take out the solid waste inside the separation box.

[0020] Preferably, the middle part of the bottom of the rotating drum is rotatably connected to the filter plate through a driving shaft, and the driving device comprises a motor, which is arranged at the bottom of the filter plate, and the output shaft of the motor is fixedly connected to the driving shaft.

[0021] In this technical solution, it should be noted that a protection box surrounding the motor can be provided at the bottom of the filter plate to protect the motor.

[0022] Preferably, a floating plate is further provided in the lower oil-water separation chamber, and the floating plate can move along the height direction of the lower oil-water separation chamber, and the density of the floating plate is between that of oil and water, and when the floating plate rises to the highest height, it is opposite to the oil outlet and forms a seal for the oil outlet. A guide rod is vertically provided at the bottom of the lower oil-water separation chamber, and the floating plate is sleeved on the guide rod. A limit plate is provided on the top of the guide rod, and the thickness of the floating plate is greater than the distance between the bottom of the limit plate and the bottom of the oil outlet.

[0023] In this technical solution, it should be noted that when oil and water fall into the lower oil-water separation chamber, if the float plate does not float up to the oil outlet, the upper oil will be discharged from the oil outlet. If the float plate gradually floats up, when the float plate rises to the oil outlet, the oil outlet will be closed. At this time, the staff can open the water outlet to drain the water.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In the present invention, the solid and liquid in the kitchen waste are separated by centrifugation, the separation efficiency is fast, and the oil and water contained in the waste itself can also be thrown out by centrifugation, making the separation more thorough. Secondly, the present invention integrates the solid-liquid separation device and the oil-water separation device, and the oil and water separated from the waste can fall into the lower oil-water separation chamber below for static separation;

[0026] 2. In the present invention, the one-way bearing, spring door, linkage rod, annular plate and vertical rod are arranged, so that when the rotating drum rotates clockwise, the solid waste in the rotating drum can be normally centrifuged. After the solid waste centrifugation is completed, the rotating drum can gradually open the spring door by rotating counterclockwise, so that the solid in the rotating drum can be automatically thrown out of the rotating drum by centrifugation, which is convenient for the staff to collect;

[0027] 3. In the present invention, by means of the one-way bearing, spring door, linkage rod, annular plate and vertical rod, when the rotating drum rotates clockwise, the solid waste in the rotating drum can be normally centrifuged. After the solid waste centrifugation is completed, the rotating drum can gradually open the spring door by rotating counterclockwise, so that the solid in the rotating drum can be automatically thrown out of the rotating drum by centrifugation, which is convenient for the staff to collect;

[0028] 4. In the present invention, a locking groove, a locking rod and a guide surface are provided. After the linkage rod is blocked by the vertical rod and rotates to a certain position, it will contact with the guide surface of the locking rod, and then squeeze the guide surface. The guide surface distributes the pressure vertically upward through its own inclined surface, so that the locking rod gradually moves upward, and in the process of the linkage rod rotating counterclockwise, the locking rod will be opposite to the locking groove on the linkage rod up and down. At this time, the locking rod is inserted into the locking groove by elastic force, limiting the linkage rod, so that the spring door is always in an open state.

[0029] 5. In the present invention, a low-speed rotation mode and a high-speed rotation mode are set. The low-speed rotation mode facilitates the locking rod to be smoothly inserted into the locking groove, and the high-speed rotation mode is used for the centrifugal effect of the solid.

[0044] Example

[0045] like Figure 1-5 As shown, a kitchen waste oil-water separation device is disclosed in an embodiment of the present invention, including a separation box 10 with a feed inlet on the top, wherein the separation box 10 is embedded with a filter plate 40, and the filter plate 40 divides the separation box 10 into an upper solid-liquid separation chamber 13 and a lower oil-water separation chamber 14; a rotating cylinder 20 is provided on the top of the filter plate 40, and the rotating cylinder 20 is driven to rotate by a driving device, and a liquid outlet is provided on the side wall of the rotating cylinder 20; an oil outlet 141 and a water outlet 142 are respectively provided on the side wall and the top of the lower oil-water separation chamber 14, and the oil outlet 141 and the water outlet 142 both have valves. It should be noted that the separation box 10 is cylindrical, and a support leg 12 is provided at the bottom thereof. The number of the support legs 12 is specifically four and is made of steel. The bottom thereof can be fixed to the ground by bolts. A sealing cover is provided at the top of the separation box 10 (the sealing cover is hinged to the rotating drum 20, not shown in the figure), and the feed port can be provided on the sealing cover. There is a gap between the bottom of the rotating drum 20 and the filter plate 40, and the two are concentric. In this scheme, when it is necessary to process the kitchen waste, the waste is first put into the rotating drum 20 through the feed port, and then the rotating drum 20 is driven to rotate by the driving device. After the rotating drum 20 rotates, the oil and water in the waste are thrown out by centrifugation, and the thrown out oil and water fall into the lower oil-water separation chamber 14 through the small holes on the filter plate 40, and are left to stand in the lower oil-water separation chamber 14 for a period of time until the oil and water are separated, and then the staff discharges the oil and water respectively through the oil outlet 141 and the water outlet 142 to achieve the purpose of oil-water separation. In summary, in the present invention, the solid and liquid in the kitchen waste are separated by centrifugation, the separation efficiency is fast, and the oil and water contained in the waste itself can also be thrown out by centrifugation, making the separation more thorough. Secondly, the present invention integrates the solid-liquid separation device and the oil-water separation device, and the oil and water separated from the waste can fall into the lower oil-water separation chamber 14 below for static separation.

[0046] like Figure 2-Figure 5As shown, in this embodiment, a plurality of solid discharge ports are provided on the side wall of the rotating cylinder 20, and a spring door 30 is provided at the solid discharge port, and the spring door 30 is hinged to the rotating cylinder 20 through a rotating shaft 31; a linkage rod 32 is provided at the bottom of the rotating shaft 31 through the rotating cylinder 20, and the linkage rod 32 is arranged along the diameter direction of the rotating shaft 31, and an annular groove 41 is provided at the top of the filter plate 40, and an annular plate 42 is connected to the annular groove 41 through a one-way bearing 43, and a vertical rod 44 is provided at the top of the annular plate 42, and the top of the vertical rod 44 is higher than the top of the linkage rod 32. It should be noted that the spring door 30 is a door classified according to the door opening method in the door classification, and the door equipped with a spring 23 hinge will automatically close after opening; the one-way bearing 43 is a bearing that can rotate freely in one direction and is locked in another direction. In the present solution, the inner ring of the one-way bearing 43 is interference-connected with the outer side wall of the annular plate 42, and the outer ring of the one-way bearing 43 is fixedly connected with the inner wall of the annular groove 41. The counterclockwise rotation direction of the annular plate 42 is the direction in which the inner ring and the outer ring of the one-way bearing 43 are locked, that is, the annular plate 42 cannot rotate in the counterclockwise direction; the clockwise rotation direction of the annular plate 42 is the direction in which the inner ring and the outer ring of the one-way bearing 43 are movably connected, that is, the annular plate 42 can rotate in the clockwise direction; in the present solution, it is necessary to further explain that after the centrifugal operation of the kitchen waste in the rotating drum 20 is completed, the solid waste needs to be taken out and recycled. However, since the rotating drum 20 has a certain depth, it is not convenient to recycle. Based on this, the present invention is provided with a one-way bearing 43, a spring door 30, a linkage rod 32, annular plate 42 and a vertical rod 44. When the driving device drives the rotating drum 20 to rotate clockwise, the rotating drum 20 performs centrifugal treatment on the garbage. Since the outer ring and the inner ring of the one-way bearing 43 are in an active state at this time, the linkage rod 32 and the vertical rod After the contact with the vertical rod 44, the vertical rod 44 has no limiting effect. Therefore, the linkage rod 32 will drive the vertical rod 44 and the annular plate 42 connected to the vertical rod 44 to rotate clockwise while rotating with the rotating drum 20. The spring door 30 is in a closed state to prevent the garbage from being thrown out during the centrifugation process. When the garbage centrifugation is completed, the garbage inside the rotating drum 20 needs to be taken out. At this time, the rotating drum 20 is controlled to rotate counterclockwise by the driving device. At this time, since the outer ring and the inner ring of the one-way bearing 43 are locked, State, therefore, after the linkage rod 32 contacts with the vertical rod 44, the vertical rod 44 is in a fixed state and has a limiting effect. Therefore, while the linkage rod 32 rotates with the rotating drum 20, after contacting with the vertical rod 44, it will gradually rotate counterclockwise due to the obstruction of the vertical rod 44, thereby driving the rotating shaft 31 to rotate counterclockwise. The counterclockwise rotation of the rotating shaft 31 will drive the spring door 30 to gradually open. At this time, the solid waste in the rotating drum 20 will be thrown into the separation box 10 through centrifugal action, which is convenient for the staff to collect.To sum up, in the present invention, by providing the one-way bearing 43, the spring door 30, the linkage rod 32, the annular plate 42 and the vertical rod 44, the solid waste in the rotating drum 20 can be normally centrifuged when the rotating drum 20 rotates clockwise. After the centrifugation of the solid waste is completed, the rotating drum 20 can gradually open the spring door 30 by rotating counterclockwise, so that the solids in the rotating drum 20 can be automatically thrown out of the rotating drum 20 through centrifugation, which is convenient for the staff to collect.

[0047] like Figure 2-Figure 5 As shown, in this embodiment, a locking groove 33 is provided at the top of the linkage rod 32, and a locking rod 21 which can be inserted into the locking groove 33 is elastically connected to the bottom of the rotating cylinder 20, and a guide surface 22 is inclined on the side wall of the locking rod 21, and the guide surface 22 cooperates with the linkage rod 32. It should be noted that when the rotating cylinder 20 rotates counterclockwise, since the linkage rod 32 will be offset from the vertical rod 44 after a period of time, the spring door 30 will automatically close due to its own elastic force. Based on this, the present invention is provided with a locking groove 33, a locking rod 21 and a guide surface 22. After the linkage rod 32 is blocked by the vertical rod 44 and rotates to a certain position, it will contact the guide surface 22 of the locking rod 21, and then squeeze the guide surface 22. The guide surface 22 distributes the pressure vertically upward through its own inclined surface, so that the locking rod 21 gradually moves upward, and in the process of the linkage rod 32 rotating counterclockwise, the locking rod 21 will be opposite to the locking groove 33 on the linkage rod 32. At this time, the locking rod 21 is inserted into the locking groove 33 by elastic force to limit the linkage rod 32, so that the spring door 30 is always in an open state.

[0048] like Figure 2-Figure 5 As shown, in this embodiment, during the process of inserting the locking rod 21 into the locking groove 33, before the locking rod 21 is inserted into the locking groove 33, the rotating drum 20 rotates at a low speed, and after the locking rod 21 is inserted into the locking groove 33, the rotating drum 20 switches from low speed rotation to high speed rotation. It should be noted that after the locking rod 21 rises to the top of the locking groove 33 through the cooperation of the inclined surface and the linkage rod 32, if the rotation speed of the rotating drum 20 is too fast at this time, the speed at which the locking rod 21 is inserted into the locking groove 33 will be much lower than the speed at which the locking groove 33 rotates, thereby causing the locking rod 21 to fail to be smoothly inserted into the lock. Therefore, this solution sets a low-speed rotation mode and a high-speed rotation mode. The low-speed rotation mode facilitates the locking rod 21 to be smoothly inserted into the locking groove 33, and the high-speed rotation mode is used for the centrifugal effect of the solid. This solution can be realized by providing a sensor in the locking groove 33. Before the locking rod 21 contacts the locking groove 33, the rotating drum 20 rotates at a low speed. After the locking rod 21 is inserted into the locking groove 33, the sensor sends a sensing signal to the driving device, and the driving device drives the rotating drum 20 to rotate at a high speed.

[0049] like Figure 4-Figure 5 As shown, in this embodiment, the top of the rotating cylinder 20 is provided with an annular strip 24, and the top of each locking rod 21 slides through the rotating cylinder 20 and is fixedly connected to the annular strip 24. The annular strip 24 is connected to the rotating cylinder 20 through a spring 23, and the spring 23 is sleeved on the locking rod 21. It should be noted that after the solid is thrown out of the rotating cylinder 20, the spring door 30 needs to be closed in order to perform the next solid-liquid separation operation. Therefore, the present scheme is provided with a spring 23 and annular strip 24. When the spring door 30 needs to be closed, the annular strip 24 is pulled upward, so that all the locking rods 21 move upward, so that the locking rods 21 and the locking grooves 33 are staggered up and down, and then the rotating cylinder 20 is rotated at a certain angle, so that the locking rods 21 and the locking grooves 33 are staggered left and right, and the limiting effect of the locking rods 21 and the locking grooves 33 can be released, and the spring door 30 will be reset by its own elastic force.

[0050] like Figure 1 As shown, in this embodiment, a door 11 is hinged on the side wall of the upper solid-liquid separation chamber 13. It should be noted that after the solid is thrown out of the rotating drum 20, the staff can open the door 11 to take out the solid waste inside the separation box 10.

[0051] like Figure 2 As shown, in this embodiment, the middle part of the bottom of the rotating drum 20 is rotatably connected to the filter plate 40 through a driving shaft, and the driving device includes a motor 50, which is arranged at the bottom of the filter plate 40, and the output shaft of the motor 50 is fixedly connected to the driving shaft. It should be noted that a protective box surrounding the motor 50 can be provided at the bottom of the filter plate 40 to protect the motor 50.

[0052] like Figure 2 As shown, in this embodiment, a floating plate 144 is further provided in the lower oil-water separation chamber 14, and the floating plate 144 can move along the height direction of the lower oil-water separation chamber 14. The density of the floating plate 144 is between that of oil and water, and when the floating plate 144 rises to the highest height, it is opposite to the oil outlet 141 and forms a seal for the oil outlet 141. A guide rod 143 is vertically provided at the bottom of the lower oil-water separation chamber 14, and the floating plate 144 is sleeved on the guide rod 143. A limit plate 145 is provided at the top of the guide rod 143, and the thickness of the floating plate 144 is greater than the distance between the bottom of the limit plate 145 and the bottom of the oil outlet 141. It should be noted that, after the oil and water fall into the lower oil-water separation chamber 14, if the float 144 does not float up to the position of the oil outlet 141, the upper layer of oil will be discharged from the oil outlet 141; if the float 144 gradually floats up, when the float 144 rises to the oil outlet 141, the oil outlet 141 will be closed, and the staff can then open the water outlet 142 to drain the water.

[0053] The principle of this embodiment is:

[0054] When it is necessary to process the kitchen waste, the waste is first put into the rotating drum 20 through the feeding port, and then the rotating drum 20 is rotated clockwise by the motor 50. At this time, the rotating drum 20 performs centrifugal processing on the waste. Since the outer ring and the inner ring of the one-way bearing 43 are in an active state at this time, after the linkage rod 32 contacts the vertical rod 44, the vertical rod 44 has no limiting effect. Therefore, when the linkage rod 32 rotates with the rotating drum 20, after contacting the vertical rod 44, it will drive the vertical rod 44 and the annular plate 42 connected to the vertical rod 44 to rotate clockwise, and the elastic The spring door 30 is in a closed state to prevent the garbage from being thrown out during the centrifugation process; and when the garbage centrifugation is completed, the garbage inside the rotating drum 20 needs to be taken out. At this time, the rotating drum 20 is controlled by the driving device to rotate counterclockwise. At this time, since the outer ring and the inner ring of the one-way bearing 43 are in a locked state, after the linkage rod 32 contacts the vertical rod 44, the vertical rod 44 is in a fixed state and has a limiting effect. Therefore, when the linkage rod 32 rotates with the rotating drum 20, after contacting the vertical rod 44, it will contact the guide surface 22 of the locking rod 21, and then The guide surface 22 is squeezed, and the guide surface 22 distributes the pressure vertically upward through its own inclined surface, so that the locking rod 21 gradually moves upward, and in the process of the linkage rod 32 rotating counterclockwise, the locking rod 21 will be opposite to the locking groove 33 on the linkage rod 32. At this time, the locking rod 21 is inserted into the locking groove 33 by elastic force, and the linkage rod 32 is limited, so that the spring door 30 is always in the open state. It will gradually rotate counterclockwise due to the obstruction of the vertical rod 44, thereby driving the rotating shaft 31 to rotate counterclockwise, and the rotating shaft 31 rotates counterclockwise. This will then drive the spring door 30 to gradually open. At this time, the solid waste in the rotating drum 20 will be thrown into the separation box 10 through centrifugal action, making it convenient for the staff to open the opening and closing door 11 for collection; when the oil and water fall into the lower oil-water separation chamber 14, if the float 144 does not float to the position of the oil outlet 141, the upper layer of oil will be discharged from the oil outlet 141. If the float 144 gradually floats up, when the float 144 rises to the oil outlet 141, the oil outlet 141 will be closed, and the staff can open the water outlet 142 to discharge the water.
