Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, specifically to an automated waste sorting station. Background Technology

[0002] Automated waste sorting stations, also known as smart waste sorting stations, are modern waste collection facilities that integrate technologies such as the Internet of Things, artificial intelligence, and automated control. Compared with traditional waste stations, they not only have basic waste storage functions, but also can achieve automatic sorting, overflow monitoring, intelligent deodorization, and remote management, effectively improving waste treatment efficiency and reducing environmental pollution. Solid-liquid separation of kitchen waste is also one of the important functions of automated waste sorting stations.

[0003] In existing automated waste sorting facilities, the treatment of liquid waste from kitchen waste typically involves using extrusion components to directly separate the liquid from the solids. While this method effectively separates most of the liquid waste, in practice, due to the complex composition, high fiber content, and strong adsorption properties of kitchen waste, even under high pressure, some residual liquid will still adhere to its surface. This is mainly due to the inherent characteristics of the material and uneven pressure distribution during the extrusion process, not because the equipment is completely ineffective. Furthermore, if there is a significant amount of residual liquid, contact with air or collection devices poses a risk of bacterial growth, odor generation, and secondary pollution, thus affecting subsequent processing efficiency and environmental hygiene. Therefore, since it does not meet the existing needs, we propose an automated waste sorting station. Summary of the Invention

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1, please refer to Figures 1-8 When users need to perform solid-liquid separation on some processed kitchen waste, they first need to pour the kitchen waste to be processed into the surface of the pressing lower plate 203 on the processing table 2. Since there are several pressing strips 210 on the pressing lower plate 203, it should be noted that the pressing strips 210 are all made of rigid materials, and a certain distance is maintained between adjacent pressing strips 210. After the corresponding pretreatment (such as crushing, fermentation, etc.), most of the free water in the kitchen waste has been removed, and the form has been changed to a moist granular state, which is convenient for pressing and dehydration. This means that after the user pours the kitchen waste to be processed into the pressing lower plate 203, most of the kitchen waste will be between the two corresponding pressing strips 210, while a small part of the kitchen waste will be on the top surface of the pressing strips 210. At this time, the user can start the external motor set on the equipment platform 1. Since the output end of the external motor is fixedly connected to the transmission screw 103, and two movable slide rods 102 are also fixedly set on both sides of the transmission screw 103, and the transmission screw 103 and the two movable slide rods 102 are all movably connected to the connecting frame 101 that is integrally set with the extrusion upper plate 105, and the transmission screw 103 is also connected to the connecting frame 101, this means that when the transmission screw 103 is started and rotated accordingly by the external motor, the extrusion upper plate 105 will reciprocate on the transmission screw 103 through the connecting frame 101. The two movable slide rods 102 are also set to stabilize and guide the extrusion upper plate 105 while it is moving. When the upper extrusion plate 105 moves downward, the lower extrusion plate 203 located directly below it gradually comes into contact with it. Once in contact, the upper extrusion plate 105 presses down on the lower extrusion plate 203, squeezing the unprocessed kitchen waste on it. It should be noted that a screen 227 is provided between the bottoms of two adjacent extrusion bars 210. This screen allows waste liquid to drain from the gaps between the extrusion bars 210 into the screen 227, and then flow into the receiving cavity 216 below the lower extrusion plate 203. The screen 227 is made of an elastic material, allowing it to deform during subsequent lateral extrusion processing. This method also completes the longitudinal extrusion processing of most of the waste liquid from the inspected kitchen waste.

[0028] It should be noted that the elastic screen 227 structure described in this embodiment not only does not weaken the squeezing effect, but is actually the key to achieving efficient two-stage dehydration and integrated device functions. In the longitudinal squeezing stage, when the upper squeezing plate 105 applies vertical pressure downwards, the rigid squeezing strip 210, as the main load-bearing component, bears and transmits most of the mechanical pressure, thereby strongly squeezing the main body of kitchen waste and releasing a large amount of free waste liquid. At this time, the core function of the elastic screen 227 is to guide and adapt. Due to its own filter pores, the squeezed waste liquid can quickly flow into the lower receiving cavity 216 through the holes of the screen 227 after passing through the gaps between the squeezing strips 210, effectively avoiding liquid accumulation. At the same time, the elastic material of the screen 227 allows it to undergo controllable and beneficial elastic deformation when subjected to local pressure. This deformation allows some kitchen waste to sink slightly, ensuring that the pressure of the upper extrusion plate 105 is evenly applied to the entire upper surface of the waste material. This avoids uneven pressure distribution caused by individual hard objects pushing against it, effectively enhancing rather than weakening the sufficiency and effectiveness of the longitudinal extrusion. In the subsequent transverse extrusion stage, when the external cylinder drives the push rod 206 and the extrusion push plate 221 to push the extrusion strips 210 to contract laterally, the elastic properties of the elastic screen 227 become a necessary condition for achieving this function. It can fit tightly against the bottom of the moving extrusion strips 210 and deform accordingly without breaking. This not only ensures the smooth progress of the transverse extrusion movement, but also forms a dynamic seal at the bottom of the gap between the extrusion strips 210 to prevent leakage of fine particles, while continuing to allow the residual liquid from the secondary extrusion to be smoothly introduced into the receiving cavity 216.

[0029] After the kitchen waste is longitudinally squeezed by the upper extrusion plate 105, since most of the kitchen waste is located between two adjacent extrusion bars 210, a portion of the kitchen waste will be squeezed into the gap between the two extrusion bars 210 after being squeezed by the upper extrusion plate 105. At the same time, this portion of the kitchen waste not only contains a small amount of waste liquid that was not squeezed by the upper extrusion plate 105, but also absorbs a portion of the waste liquid produced by the kitchen waste after being squeezed by the upper extrusion plate 105. At this time, the user can start the external cylinder that is fixedly connected to the two push rods 206. Since two connecting through holes are also opened on one side surface of the processing table 2, and each connecting through hole is equipped with a push rod 206, and the other end of the two push rods 206 is fixedly connected to the extrusion push plate 221, and the extrusion lower plate 203 is also provided with a receiving through groove on the side surface near the push rods 206, the two push rods 206 will drive the extrusion push plate 221 through the receiving through groove and complete the extrusion of the extrusion strip 210 by starting the external cylinder; Since each extrusion bar 210 is slidably mounted inside the limiting groove on the processing table 2 by means of movable sliders 225 integrally set at both ends, and adjacent movable sliders 225 are connected by a second spring 223, when the extrusion push plate 221 pushes one extrusion bar 210 close to the extrusion push plate 221, the other extrusion bars 210 will also move away from the extrusion push plate 221 inside the limiting groove under the pushing force of the extrusion push plate 221. After several extrusion bars 210 have moved, the kitchen waste between adjacent extrusion bars 210 will also be laterally extruded under the movement of the extrusion bars 210, so as to complete the waste liquid treatment of kitchen waste that is deep in the gap between two extrusion bars 210. The extruded waste liquid will also fall into the receiving cavity 216 below the extrusion lower plate 203 through the gap between the extrusion bars 210. It should be noted that the second spring 223 is designed to maintain a gap between adjacent squeezing bars 210 under the elastic force of the second spring 223, allowing the corresponding food waste to be contained. On the other hand, when the squeezing bar 210 is squeezed, the second spring 223 will also tighten accordingly. When the squeezing bar 210 is released from the squeeze, the reset elastic force of the second spring 223 can also quickly reset the adjacent squeezing bars 210, so as to facilitate the subsequent feeding and processing of food waste.

[0030] Example 2 aims to further address the problem of residual waste liquid. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-8 Since a scraper 201 is installed inside the surface of the receiving cavity 216 away from the push rod 206, on the one hand, a winding roller 202 is also installed on the side of the receiving cavity 216 near the push rod 206, and the winding roller 202 is rotatably mounted on the inner wall of the receiving cavity 216 through a torsion spring (not shown in the figure) and a rotating rod. At the same time, a corresponding traction rope is wound on the winding roller 202. On the other hand, two fixed pulleys 204 are also installed on the inner wall of the receiving cavity 216. One fixed pulley 204 (fixed pulley 204A) is installed above the winding roller 202, and the other fixed pulley 204 (fixed pulley 204B) is installed on the side near the scraper 201. At the same time, a movable pulley 208 (movable pulley 208A) is installed on the scraper 201, and a movable pulley 208 (movable pulley 208B) is also installed on the extrusion push plate 221.

[0031] It should be noted that the traction rope is wound along a specific path: its first end is fixed to the extrusion push plate 221, and the rope body is wound around the winding roller 202. The traction rope then sequentially passes over the movable pulley 208B, movable pulley 208A, fixed pulley 204B, and fixed pulley 204A, while its end is fixed to the receiving cavity 216. The core of the working principle and displacement relationship of this pulley system lies in the change of the traction rope's fixing point and the combined action of the double movable pulleys 208. The first end of the traction rope is rigidly connected to the extrusion push plate 221, so the displacement of this point is consistent with the displacement S of the extrusion push plate 221, and can be used as a reference for power input.

[0032] Its specific working principle and displacement relationship are as follows: When the extrusion push plate 221 moves a distance S, it pulls the first end of the traction rope to move a distance S. This pulling force is transmitted to the entire pulley system through the traction rope. For this specific pulley 204 group (including a movable pulley 208B that moves with the power and a load movable pulley 208A), the moving distance L of the load (i.e., the scraper 201 that is rigidly connected to the shaft of the movable pulley 208A) is half of the moving distance S of the power input end (extrusion push plate 221). Therefore, there is the following physical relationship between the moving distance S of the extrusion push plate 221 and the moving distance L of the scraper 201: S = 2 × L.

[0033] In other words, when lateral extrusion is performed, as the external cylinder pushes the push rod 206 and the extrusion push plate 221 forward a distance S, the moving pulley 208A is pulled by the transmission of the traction rope and the double-moving pulley 208 system, so that the scraper 201 moves, and the moving distance is S / 2. This movement design utilizes the principle of the pulley system to convert the cylinder drive stroke into the required working stroke.

[0034] When the push rod 206 moves backward, the traction rope loosens. At this time, the winding roller 202 rotates under the reset torque of the torsion spring, automatically retracting and winding the traction rope, thereby effectively pulling the scraper 201 to accurately reset along the moving path, so as to prepare for the next operation.

[0035] When the scraper 201 moves, on the one hand, the top of the scraper 201 is provided with a corresponding scraping slope. That is to say, when the scraper 201 moves along the bottom of the extrusion bar 210, the scraping slope can scrape off the residual liquid at the bottom of the extrusion bar 210.

[0036] On the other hand, since a movable plate 214 is also provided inside the wiper 201, the bottom of the movable plate 214 is connected to the inner wall of the bottom of the wiper 201 by several first springs 218, and both ends of the movable plate 214 are provided with limit slide rods 213, and the other end of the limit slide rod 213 is slidably disposed inside the limit track groove 226. It should be noted that the limit track groove 226 is composed of a movable straight groove and several movable arc grooves. That is to say, when the wiper 201 moves, the limit slide rod 213 will first move along the movable straight groove in the limit track groove 226; when the wiper 201 moves to the bottom of the extrusion strip 210, the limit slide rod 213 will slide from the movable straight groove into the first movable arc groove. At this time, restricted by the movable arc groove, the limit slide rod 213 will drive the movable plate 214 to move upward inside the wiper 201.

[0037] Since several striking rods 211 are fixedly installed on the top of the moving plate 214, when the moving plate 214 moves upward, the striking rods 211 above the moving plate 214 will move with the moving plate 214. When the limiting slide rod 213 slides to the highest point of the moving arc groove, the striking rod 211 will just complete the collision with the bottom of the squeezing strip 210. This collision can also shake off the waste liquid remaining on the kitchen waste to a certain extent, so as to facilitate subsequent cleaning. Furthermore, since several moving arc grooves are opened in the limiting track groove 226, the moving plate 214 will move up and down repeatedly during the movement of the scraper 201. That is, the striking rods 211 will continuously strike the bottom of the squeezing strip 210. This setting can further improve the cleaning effect of residual waste liquid.

[0038] Meanwhile, a dynamic sealing structure is provided between the moving plate 214 and the inner wall of the scraper 201, forming a sealed cavity below it. When the moving plate 214 moves upward, the volume of the cavity increases, thereby generating negative pressure.

[0039] Since several suction nozzles 209 are also installed on the scraper 201, a connecting conduit 217 is fixedly installed below the suction nozzle 209, and the connecting conduit 217 is connected to the cavity below the moving plate 214. An inlet check valve is provided at the inlet of the suction nozzle 209, which only allows liquid to flow into the connecting conduit 217; an outlet check valve is provided at the first drain port 219 opened at the bottom of the cavity, which only allows liquid to drain out of the cavity.

[0040] Therefore, when the moving plate 214 moves upward to generate negative pressure, the outlet check valve closes and the inlet check valve opens. The negative pressure in the cavity is transmitted to the suction nozzle 209 through the connecting conduit 217, thereby completing the suction of the residual liquid at the bottom of the extrusion strip 210. When the moving plate 214 moves downward under the action of the spring, the cavity volume decreases and the pressure increases. The inlet check valve closes and the outlet check valve opens, thereby discharging the sucked waste liquid out of the scraper 201 through the first drain port 219. Through the combination of the above-mentioned mechanical pump suction structure and scraping and knocking functions, the cleaning effect of residual waste liquid is significantly improved.

[0041] Meanwhile, since the output end of the drive motor 220 is fixedly connected to the transmission shaft located inside the second overlapping slot (not shown in the figure), and one end of the extrusion plate 203 is also fixedly sleeved on the transmission shaft, the angle of the extrusion plate 203 can be flipped by rotating the transmission shaft. When the adsorption component is reset, the external cylinder and the external motor are started in reverse. This causes the extrusion push plate 221 and the extrusion upper plate 105, which are connected to the external cylinder and the external motor, to reset. After the adsorption component, the extrusion push plate 221 and the pressing component have all been reset, the drive motor 220 set on the processing table 2 is started. This causes the transmission shaft fixedly connected to the drive motor 220 to drive the extrusion lower plate 203 to flip. At the same time, since a collection box 106 is also set on one side of the equipment table 1, the kitchen waste that has been treated with waste liquid on the extrusion lower plate 203 will fall into the collection box 106 under the flipping action of the extrusion lower plate 203, thus completing the collection of the kitchen waste that has been treated with waste liquid. It should be noted that since a first overlapping slot (not shown in the figure) is also provided on the processing table 2, and an overlapping block 207 is also provided on the extrusion plate 203 corresponding to the position of the first overlapping slot, when the extrusion plate 203 is flipped toward the processing table 2, the extrusion plate 203 will eventually overlap with the first overlapping slot through the overlapping block 207. This setting also improves the stability of the extrusion plate 203 to a certain extent. It should be noted that since two second drain ports 224 are also provided on the surface of the processing table 2 away from the collection box 106, and the two second drain ports 224 are connected to the inside of the receiving cavity 216, when the waste liquid inside the receiving cavity 216 is stored to a certain amount, the user can open the second drain ports 224 to discharge the waste liquid inside the receiving cavity 216 into the outside of the processing table 2.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
