Description

Technical Field

[0001] This invention relates to the field of kitchen waste separation equipment technology, and in particular to a solid-liquid separation device and a garbage truck. Background Technology

[0002] In related technologies, food waste has a high water content and needs to be separated into solid and liquid components after being transported to the waste station before it can be recycled. Therefore, solid-liquid separation food waste trucks have been manufactured to address the food waste treatment process, and these trucks have become an indispensable type of food waste transport vehicle.

[0003] Existing food waste separation vehicles mostly use filter plates, filter screens, or filter cylinders to separate food waste into solid and liquid components. Solid waste remains above the filter plates, filter screens, or filter cylinders, while liquid waste flows to the bottom of the filter plates, filter screens, or filter cylinders due to gravity. However, this method of using gravity for solid-liquid separation has poor processing effect and low processing efficiency when separating food waste into solid and liquid components. Summary of the Invention

[0004] The main objective of this invention is to provide a solid-liquid separation device and garbage truck, aiming to solve the technical problem that existing food waste separation trucks mostly use filter plates, filter screens, or filter cylinders to separate food waste into solid and liquid components. Solid waste remains above the filter plates, filter screens, or filter cylinders, while liquid waste flows below the filter plates, filter screens, or filter cylinders due to gravity. However, this method of solid-liquid separation using gravity has poor processing effect and low processing efficiency when separating food waste into solid and liquid components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides a solid-liquid separation device, comprising:

[0007] The housing has an inclined partition that divides the internal space of the housing into a separation chamber and a liquid storage chamber. The separation chamber and the liquid storage chamber are connected at the lowest point of the partition, and an anti-backflow device is provided at the connection between the separation chamber and the liquid storage chamber.

[0008] The centrifuge cylinder and the drive mechanism are provided. The drive mechanism is disposed in the housing. The centrifuge cylinder is rotatably disposed in the separation chamber. The centrifuge cylinder is used to hold the solid-liquid mixed waste to be separated. The centrifuge cylinder has a discharge hole that communicates with the separation chamber. When the drive mechanism drives the centrifuge cylinder to rotate, the liquid separated from the solid-liquid mixed waste is discharged into the separation chamber through the discharge hole, and then enters the liquid storage chamber through the anti-backflow device. The liquid storage chamber is provided with a drain port for discharging the liquid.

[0009] Optionally, in the above-mentioned solid-liquid separation device, a feed inlet for placing the solid-liquid mixed waste is formed on one side of the centrifuge cylinder. The solid-liquid separation device also includes a push-pull mechanism located in the separation chamber. The fixed end of the push-pull mechanism is disposed at one end of the centrifuge cylinder, and the free end of the push-pull mechanism is connected to a plate. The push-pull mechanism can drive the plate to reciprocate between an initial position and an end position along the extension direction of the centrifuge cylinder. The feed inlet is disposed between the initial position and the end position. When the push-pull mechanism drives the plate to move from the initial position to the end position, the plate pushes the solid-liquid mixed waste in the centrifuge cylinder to the end position, so that the solid-liquid mixed waste is away from the feed inlet.

[0010] Optionally, in the above-mentioned solid-liquid separation device, an inlet is formed on the top of the box, and a top cover is provided at the inlet. The top cover is connected to the box and is used to open or close the inlet.

[0011] The solid-liquid separation device further includes a first sensing module and a second sensing module. Both the first sensing module and the second sensing module are disposed on the inner wall of the separation chamber. The first sensing module is disposed at the initial position of the push-pull mechanism to sense the plate body when it is in the initial position. The second sensing module is used to sense the centrifuge when the feed inlet rotates with the centrifuge to a position corresponding to and connected with the feed port.

[0012] Optionally, in the above-mentioned solid-liquid separation device, the solid-liquid separation device further includes a guide frame and a lifting drive component. The guide frame and the lifting drive component are both disposed outside the housing. The guide frame is used to install an external cylinder for holding solid-liquid mixed waste. The lifting drive component is connected to the cylinder and is used to drive the cylinder to climb along the guide frame to the feed inlet. When the second sensing module senses the centrifuge cylinder and the first sensing module senses the plate at the initial position, the solid-liquid mixed waste contained in the cylinder is poured into the centrifuge cylinder through the feed inlet.

[0013] Optionally, in the above-mentioned solid-liquid separation device, the push-pull mechanism includes a push-pull drive component and a mounting frame. The main body of the push-pull drive component is connected to the inner wall of the centrifuge cylinder through the mounting frame, and the output shaft of the push-pull drive component is connected to the plate body.

[0014] Optionally, in the above-mentioned solid-liquid separation device, an installation cylinder communicating with the centrifuge cylinder is further provided in the separation chamber. The push-pull mechanism is disposed in the installation cylinder. The driving mechanism includes a rotary drive component and an adapter component. One end of the installation cylinder is connected to the centrifuge cylinder, and the other end of the installation cylinder is connected to the output shaft of the rotary drive component through the adapter component. The rotary drive component is used to drive the installation cylinder to rotate so as to drive the centrifuge cylinder to rotate in the separation chamber.

[0015] Optionally, in the above-mentioned solid-liquid separation device, a discharge port is formed at one end of the housing, and a discharge port is formed at one end of the centrifuge cylinder corresponding to the discharge port. A door is provided at the discharge port, and the outer top of the door is connected to the housing through an opening and closing mechanism. A cover is provided at the discharge port, and the cover is connected to the centrifuge cylinder. The cover and the door are connected through a connecting assembly. The opening and closing mechanism is used to drive the door to open or close the discharge port, and correspondingly causes the door to drive the cover to open or close the discharge port through the connecting assembly.

[0016] Optionally, in the above-mentioned solid-liquid separation device, the opening and closing mechanism includes an opening and closing drive component and a transmission plate. The transmission plate includes a first connecting arm, a second connecting arm, and a third connecting arm. The opening and closing drive component is installed on the top of the housing near the discharge port. The output shaft of the opening and closing drive component is hinged to one end of the first connecting arm, one end of the second connecting arm is hinged to the housing door, and the third connecting arm is hinged to the housing. The opening and closing drive component is used to drive the first connecting arm to move around the hinge point between the third connecting arm and the housing, so as to drive the housing door to open or close the discharge port through the second connecting arm, and correspondingly cause the housing door to drive the door cover to open or close the discharge port through the connecting assembly.

[0017] Optionally, in the above-mentioned solid-liquid separation device, the connecting assembly includes a push-pull rod and a universal coupling. The universal coupling is disposed on the door cover, one end of the push-pull rod is hinged to the box door, and the other end of the push-pull rod is hinged to the universal coupling.

[0018] Secondly, the present invention provides a garbage truck that uses the solid-liquid separation device as described above. The garbage truck includes a frame and a lifting drive component disposed on the frame. One end of the solid-liquid separation device is hinged to the frame, and the other end of the solid-liquid separation device is hinged to the lifting drive component.

[0019] The above-described one or more technical solutions provided by this invention can have the following advantages or at least achieve the following technical effects:

[0020] This invention proposes a solid-liquid separation device and garbage truck. By driving a centrifuge drum to rotate, it performs solid-liquid separation on kitchen waste placed inside the centrifuge drum, improving the efficiency of solid-liquid separation of kitchen waste. The solids separated from the kitchen waste are intercepted inside the centrifuge drum, while the liquids separated from the kitchen waste are collected in a storage chamber. This allows for separate management of the solids and liquids separated from the kitchen waste. Furthermore, an anti-backflow device is installed at the connection between the storage chamber and the separation chamber to prevent the liquid in the storage chamber from flowing back into the separation chamber and re-contacting the solids, thus preventing the dehydrated kitchen waste from being re-wetted and causing incomplete dry-wet separation of the kitchen waste. This ensures the solid-liquid separation treatment effect and efficiency of kitchen waste. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0032] It should be noted that in the embodiments of the present invention, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0033] In this invention, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system. Without further limitation, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or system that includes that element. Furthermore, the meaning of "and / or" throughout the text includes three parallel options; for example, "A and / or B" includes option A, option B, or options where both A and B are satisfied.

[0034] In this invention, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0036] In this invention, the use of suffixes such as "module," "component," "part," "unit," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" can be used interchangeably.

[0037] For those skilled in the art, the specific meanings of the above terms in this invention can be understood according to the specific circumstances. Furthermore, the technical solutions of the various embodiments can be combined with each other; however, this is based on the premise that those skilled in the art can implement them.

[0038] The inventive concept of the present invention will be further explained below with reference to some specific embodiments.

[0039] This invention proposes a solid-liquid separation device and a garbage truck.

[0040] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 , Figure 1 This is a partial perspective structural diagram of an embodiment of the solid-liquid separation device of the present invention. Figure 3 for Figure 1 Enlarged structural diagram at point A Figure 4 for Figure 1 Enlarged structural diagram at point B Figure 5 for Figure 1 Enlarged structural diagram at point C.

[0041] In one embodiment of the present invention, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a solid-liquid separation device includes a housing 100, a centrifuge cylinder 400, and a drive mechanism. An inclined partition 200 is provided in the housing 100, dividing the internal space of the housing 100 into a separation chamber 110 and a liquid storage chamber 120. The separation chamber 110 and the liquid storage chamber 120 are connected at the lowest point of the partition 200. An anti-backflow component 300 is provided at the connection between the separation chamber 110 and the liquid storage chamber 120. The drive mechanism is disposed within the housing 100, and the centrifuge cylinder 400 can... The centrifuge cylinder 400 is rotatably mounted in the separation chamber 110 and is used to hold the solid-liquid mixed waste to be separated. The centrifuge cylinder 400 has a discharge hole 410 that communicates with the separation chamber 110. When the driving mechanism drives the centrifuge cylinder 400 to rotate, the liquid separated from the solid-liquid mixed waste is discharged into the separation chamber 110 through the discharge hole 410, and then enters the liquid storage chamber 120 from the separation chamber 110 through the anti-backflow component 300. The liquid storage chamber 120 is provided with a drain port 121 for discharging liquid.

[0042] It should be noted that, driven by the drive mechanism, the centrifuge drum 400 rotates to centrifuge the solid-liquid mixed waste to be separated placed in the centrifuge drum 400, thereby separating the solid and liquid in the solid-liquid mixed waste and dehydrating the kitchen waste.

[0043] During the dehydration process of food waste, the liquid and solid components separated from the food waste are collected separately for separate management.

[0044] It should be understood that the partition 200 divides the internal space of the housing 100 into a vertically adjacent separation chamber 110 and a liquid storage chamber 120. The separation chamber 110 is located above the liquid storage chamber 120, and the centrifuge cylinder 400 is located in the separation chamber 110. When the centrifuge cylinder 400 centrifuges the solid-liquid mixed waste, the liquid separated from the solid-liquid mixed waste is thrown out from the discharge hole 410 on the centrifuge cylinder 400 into the separation chamber 110. Under the action of force, the liquid is collected in the partition 200. Since the partition 200 is inclined in the box 100, the liquid flows vertically along the inclined direction of the partition 200 to the lowest point of the partition 200, and flows from the separation chamber 110 into the liquid storage chamber 120, so that the liquid separated from the food waste is collected in the liquid storage chamber 120, and the solid separated from the food waste is intercepted in the centrifuge 400, so as to manage the liquid and solid separated from the food waste separately.

[0045] During the waste unloading stage, the sewage discharge point is first located, and the liquid in the storage chamber 120, i.e. sewage, is discharged to the designated location through the drain outlet 121. Then, the solid waste in the centrifuge 400 is discharged to the designated location.

[0046] The anti-backflow device 300 installed at the connection between the separation chamber 110 and the liquid storage chamber 120 can only be opened in the direction of entering the liquid storage chamber 120. This is to prevent the liquid stored in the liquid storage chamber 120 from flowing back from the liquid storage chamber 120 to the separation chamber 110 and then re-contacting the solids in the centrifuge drum 400, causing the dehydrated kitchen waste to be re-wetted, resulting in incomplete dry-wet separation of the kitchen waste. This ensures the solid-liquid separation treatment effect and treatment efficiency of the kitchen waste.

[0047] As an optional implementation of this embodiment, in order to improve the actual utilization rate of the internal space of the box 100, the drive mechanism is set in the separation chamber 110 and between one end of the centrifuge cylinder 400 and the inner wall of the separation chamber 110.

[0048] As another optional implementation of this embodiment, in order to prevent food waste from corroding the drive mechanism and to ensure the service life of the drive mechanism, the drive mechanism is located outside the separation chamber 110, and the output end of the drive mechanism is connected to one end of the centrifuge cylinder 400 through a coupling.

[0049] It is worth noting that the anti-backflow component 300 is a commercially available anti-backflow floor drain, fluid check valve, or backflow preventer.

[0050] In addition, to ensure the structural stability of the centrifuge cylinder 400 during rotation, multiple bearings 470 are also sleeved around the centrifuge cylinder 400. The multiple bearings 470 are spaced apart, and the connecting parts of the multiple bearings 470 are located on the partition plate 200. The rotating parts of the multiple bearings 470 are connected to the centrifuge cylinder 400.

[0051] The technical solution of this invention improves the solid-liquid separation efficiency of kitchen waste by driving the centrifuge drum 400 to rotate. The solids separated from the kitchen waste are intercepted in the centrifuge drum 400, while the liquids separated from the kitchen waste are collected in the liquid storage chamber 120 for separate management of the solids and liquids separated from the kitchen waste. Furthermore, an anti-backflow component 300 is provided at the connection between the liquid storage chamber 120 and the separation chamber 110 to prevent the liquid in the liquid storage chamber 120 from flowing back into the separation chamber 110 and re-contacting the solids, thus preventing the dehydrated kitchen waste from being re-wetted and causing incomplete dry-wet separation of the kitchen waste. This ensures the solid-liquid separation treatment effect and efficiency of the kitchen waste.

[0052] Continue to refer to Figure 1 and Figure 3 .

[0053] Furthermore, such as Figure 1 and Figure 3 As shown, a feed inlet 420 for feeding solid-liquid mixed waste is formed on one side of the centrifuge cylinder 400. The solid-liquid separation device also includes a push-pull mechanism 500 located in the separation chamber 110. The fixed end of the push-pull mechanism 500 is located at one end of the centrifuge cylinder 400, and the free end of the push-pull mechanism 500 is connected to a plate 600. The push-pull mechanism 500 can drive the plate 600 to reciprocate between the initial position and the final position along the extension direction of the centrifuge cylinder 400. The feed inlet 420 is located between the initial position and the final position. When the push-pull mechanism 500 drives the plate 600 to move from the initial position to the final position, the plate 600 pushes the solid-liquid mixed waste in the centrifuge cylinder 400 to the final position, so that the solid-liquid mixed waste is away from the feed inlet 420.

[0054] It should be noted that, in order to facilitate the transfer of solid-liquid mixed waste from the outside of the container 100 to the centrifuge drum 400, a feed inlet 420 is formed on the side wall of the centrifuge drum 400.

[0055] It should be understood that, in order to prevent solid-liquid mixed waste from accumulating at the feed inlet 420 and causing blockage, a push-pull mechanism 500 is also provided at one end of the centrifuge drum 400. The output end of the push-pull mechanism 500, i.e. the free end, drives the plate 600 connected to it to reciprocate between the initial position and the end position in the centrifuge drum 400 along the extension direction of the centrifuge drum 400.

[0056] Specifically, when the push-pull mechanism 500 drives the plate 600 to move from the initial position to the end position, the plate 600 pushes the solid-liquid mixed waste accumulated below the opening away from the opening, making room for the next time solid-liquid mixed waste is put in; when the push-pull mechanism 500 drives the plate 600 to move from the end position to the initial position, the push-pull mechanism 500 resets the plate 600, preparing for the next process of pushing away solid-liquid mixed waste.

[0057] It is worth noting that the specific settings of the initial position and the end position can be determined according to the actual depth of the centrifuge drum 400. The function of the push-pull mechanism 500 is to drive the baffle to push the solid-liquid mixed waste away from the feed port 420. During the rotation of the centrifuge drum 400, it prevents the solid-liquid mixed waste in the centrifuge drum 400 from being thrown out of the feed port 420 into the separation chamber 110, thus avoiding equipment operation errors.

[0058] Continue to refer to Figure 1 and Figure 3 .

[0059] Furthermore, such as Figure 1 and Figure 3 As shown, the top of the housing 100 has an inlet 130, and a top cover 131 is provided at the inlet 130. The top cover 131 is connected to the housing 100 and is used to open or close the inlet 130. The solid-liquid separation device also includes a first sensing module 700 and a second sensing module 800. Both the first sensing module 700 and the second sensing module 800 are disposed on the inner wall of the separation chamber 110. The first sensing module 700 is disposed at the initial position of the push-pull mechanism 500 to sense the plate 600 when it is in the initial position. The second sensing module 800 is used to sense the centrifuge cylinder 400 when the inlet 420 rotates with the centrifuge cylinder 400 to a position corresponding to and connected with the inlet 130.

[0060] It should be noted that an inlet 130 for placing solid-liquid mixed waste is formed on the top of the box 100. During the process of the solid-liquid mixed waste entering the feed inlet 420 through the inlet 130, the sensing range of the first sensing module 700 covers the distance between the plate 600 and the first sensing module 700 when the plate 600 is in the initial position. The first sensing module 700 is used to sense the position of the plate 600, and the second sensing module 800 is used to sense the position of the feed inlet 420 on the centrifuge 400.

[0061] It should be understood that, in order to avoid equipment misoperation and improve operational safety, when the first sensing module 700 senses the plate 600, that is, when the plate 600 is in the initial position, and when the second sensing module 800 senses the centrifuge drum 400, that is, when the inlet 420 of the centrifuge drum 400 corresponds to and is connected to the inlet 130 of the box 100, the top cover 131 can be opened to ensure that the external solid-liquid mixed waste can completely enter the centrifuge drum 400 for collection and processing.

[0062] It is worth noting that a flange is formed at the feed inlet 420 of the centrifuge cylinder 400, and the sensing range of the second sensing module 800 covers the distance between the flange and the second sensing module 800.

[0063] It should also be noted that both the first sensing module 700 and the second sensing module 800 are proximity switches; the top cover 131 is hinged to the housing 100.

[0064] Furthermore, to facilitate the traction of the external cylinder used to hold the solid-liquid mixed waste, and to make the process of placing the solid-liquid mixed waste into the feed inlet 420 and the inlet 130 intelligent, ensuring that the cylinder pulled to the feed inlet 420 can completely pour the solid-liquid mixed waste it contains into the centrifuge cylinder 400, the solid-liquid separation device also includes a guide frame 900 and a lifting drive component. Both the guide frame 900 and the lifting drive component are located outside the housing 100. The guide frame 900 is used to install the external cylinder used to hold the solid-liquid mixed waste. The lifting drive component is connected to the cylinder and is used to drive the cylinder to climb along the guide frame 900 to the feed inlet 420. When the second sensing module 800 senses the centrifuge cylinder 400 and the first sensing module 700 senses the plate 600 in the initial position, the solid-liquid mixed waste contained in the cylinder is poured into the centrifuge cylinder 400 through the feed inlet 420.

[0065] Continue to refer to Figure 1 and Figure 4 .

[0066] Furthermore, such as Figure 1 and Figure 4 As shown, the push-pull mechanism 500 includes a push-pull drive component 510 and a mounting bracket 520. The main body of the push-pull drive component 510 is connected to the inner wall of the centrifuge cylinder 400 through the mounting bracket 520, and the output shaft of the push-pull drive component 510 is connected to the plate body 600.

[0067] It should be noted that, in order to ensure that the relative positional relationship between the push-pull mechanism 500 and the centrifuge cylinder 400 remains constant, thereby ensuring the accuracy and stability of the push-pull mechanism 500 driving the plate 600 to push the solid-liquid mixed waste in the centrifuge cylinder 400, the push-pull drive component 510 is installed on the inner wall of the centrifuge cylinder 400 through the mounting bracket 520.

[0068] It should be understood that the push-pull drive component 510 is a hydraulic cylinder or a motor.

[0069] Furthermore, to prevent equipment malfunctions caused by the return process of the solid-liquid mixed waste blocking plate 600 entering the centrifuge cylinder 400 from the feed inlet 420, an installation cylinder 430 communicating with the centrifuge cylinder 400 is also provided in the separation chamber 110. The push-pull mechanism 500 is disposed in the installation cylinder 430. The drive mechanism includes a rotary drive component 431 and an adapter component. One end of the installation cylinder 430 is connected to the centrifuge cylinder 400, and the other end of the installation cylinder 430 is connected to the output shaft of the rotary drive component 431 through the adapter component. The rotary drive component 431 is used to drive the installation cylinder 430 to rotate so that the centrifuge cylinder 400 rotates in the separation chamber 110.

[0070] Continue to refer to Figure 1 and Figure 5 and refer to Figure 2 , Figure 2 This is a partial perspective structural diagram of another embodiment of the solid-liquid separation device of the present invention.

[0071] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, a discharge port 140 is formed at one end of the housing 100, and a discharge port 440 is formed at one end of the centrifuge 400 corresponding to the position of the discharge port 140. A door 141 is provided at the discharge port 140. The outer top of the door 141 is connected to the housing 100 through an opening and closing mechanism 450. A cover 441 is provided at the discharge port 440. The cover 441 is connected to the centrifuge 400. The cover 441 and the door 141 are connected through a connecting assembly 460. The opening and closing mechanism 450 is used to drive the door 141 to open or close the discharge port 140, and correspondingly causes the door 141 to drive the cover 441 to open or close the discharge port 440 through the connecting assembly 460.

[0072] It should be noted that the discharge port 140 of the housing 100 and the discharge port 440 of the centrifuge 400 are on the same side and connected. In order to improve the operating efficiency of the door cover 441 and the housing door 141, the door cover 441 and the housing door 141 are linked together.

[0073] It should be understood that the top of the door 141 is hinged to the body 100 via the opening and closing mechanism 450, and the door cover 441 is hinged to the centrifuge cylinder 400.

[0074] Continue to refer to Figure 5 .

[0075] Furthermore, such as Figure 5As shown, to make the opening or closing process of the box door 141 more stable and easier to control, the opening and closing mechanism 450 includes an opening and closing drive component 451 and a transmission plate 452. The transmission plate 452 includes a first connecting arm 4521, a second connecting arm 4522, and a third connecting arm 4523. The opening and closing drive component 451 is installed at the top of the box body 100 near the discharge port 140. The output shaft of the opening and closing drive component 451 is hinged to one end of the first connecting arm 4521. One end of the second connecting arm 4522 is hinged to the box door 141, and the third connecting arm 4523 is hinged to the box body 100. The opening and closing drive member 451 is used to drive the first connecting arm 4521 to move around the hinge point between the third connecting arm 4523 and the box body 100, so as to drive the box door 141 to open or close the discharge port 440 through the second connecting arm 4522, and correspondingly cause the box door 141 to drive the door cover 441 to open or close the discharge port 440 through the connecting assembly 460.

[0076] It should be noted that the transmission plate 452 has a T-shaped structure.

[0077] It should be understood that the opening and closing drive component 451 is a hydraulic cylinder or an electric motor.

[0079] Continue to refer to Figures 1 to 5 .

[0080] Furthermore, based on the same inventive concept, this invention also proposes a garbage truck.

[0081] In this embodiment, as Figures 1 to 5 As shown, a garbage truck uses the solid-liquid separation device as described in the above embodiment. The garbage truck includes a frame 10 and a lifting drive 20 disposed on the frame 10. One end of the solid-liquid separation device is hinged to the frame 10, and the other end of the solid-liquid separation device is hinged to the lifting drive 20.

The hanging mechanism, through its guide frame 900 and lifting drive, pulls the cylinder used to hold the solid-liquid mixed waste to the inlet 420 and pours the kitchen waste in the cylinder into the centrifuge cylinder 400. After collection, the top cover 131 is closed, the hanging mechanism is reset, and the kitchen waste near the inlet 420 is pushed back by the plate 600 driven by the push-pull cylinder. The centrifuge cylinder 400 starts to rotate through the gear motor, gear motor coupling, and universal coupling 462 of the rotating cylinder cover. As the rotation speed reaches a certain speed, the liquid is discharged from the discharge hole 410 of the centrifuge cylinder 400, and the solid is intercepted in the centrifuge cylinder 400 to achieve the solid-liquid separation effect. The discharged liquid permeates into the liquid storage chamber 120 of the box 100 through the anti-backflow device to achieve the effect of separate processing of liquid and solid.

[0083] During the unloading process, such as Figure 2 As shown, first locate the sewage discharge point, discharge the liquid in the storage chamber 120 to the designated location through the drain port 121, the door cover 441 of the centrifuge 400 is connected to the rear door 141 through the push-pull rod 461, the door 141 is opened by the hydraulic cylinder so that the door cover 441 opens synchronously, the lifting drive 20, i.e. the lifting hydraulic cylinder, lifts the liquid separation device and the end that is hinged to it, so that the box 100 tilts to unload the solid waste to the designated location.

[0084] It should be understood that the specific structure of the solid-liquid separation device refers to the above embodiments. Since this garbage truck adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
