DETAILED DESCRIPTION

[0020] In order to make the technical purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] The embodiment of the present invention provides an automatic solid waste processing device 100 .

[0024] See also Figures 1 to 3 , in one embodiment of the present invention, the solid waste automatic processing equipment 100 is used to process solid waste, and includes a crushing device 120 and a cleaning device; The crushing device 120 has a feed port 121, and the feed port 121 is used to receive the solid waste. The crushing device 120 can crush the solid waste into solid waste particles; The cleaning device includes a cleaning chamber 131, a filtering chamber 132 and a water pump 133. The cleaning chamber 131 is disposed below the crushing device 120 and is used to receive the crushed solid waste; the filtering chamber 132 is used to hold the washed sewage, and a first filter screen 1321 is disposed above the filtering chamber 132; The water pump 133 has a first water inlet 1331, a second water inlet 1332 and a drain 1334. The first water inlet 1331 and the drain 1334 are respectively connected to the filter tank 132 and the cleaning tank 131. The first water inlet 1331 is used to draw the liquid in the filter tank 132 into the cleaning tank 131, and the second water inlet 1332 is used to connect to the water source. The cleaning tank 131 is also formed with a sewage discharge structure below the drain 1334 of the water pump 133. The liquid can pass through the sewage discharge structure to discharge the sewage to the filter tank 132 after passing through the first filter screen.

[0025] It can be understood that the technical solution of the present invention realizes the initial sorting of solid waste by setting the crushing device 120 and the cleaning device. Specifically, after the solid waste is crushed, a large amount of liquid is added to the cleaning bin 131 by using the water pump 133, and the liquid washes the waste, so that part of the waste is dissolved, and part of the waste with lighter weight flows to the first filter 1321 through the sewage discharge structure, thereby realizing the initial sorting of fixed waste. Therefore, the technical solution of the present invention realizes the automatic classification of solid waste.

[0026] It can also be understood that the provision of the filter chamber 132 can achieve the recycling of cleaning water, which is beneficial to saving resources.

[0027] It should also be noted that the solid waste in the present invention may refer to a single solid waste, such as waste plastic, waste metal or waste glass, or a mixture of solid waste. In specific application methods, those skilled in the art can adjust different parameters to achieve automatic processing and classification of various solid wastes.

[0028] Specifically, when the solid waste is waste metal products, after the waste metal products pass through the crushing device 120, the waste particles are washed in the cleaning bin 131, so that the mixed plastic particles or some liquids with a density less than water can flow to the filter bin 132 along with the liquid, and can be used to collect such materials through the first filter screen 1321. Correspondingly, some soluble impurities in the waste metal products or impurities that can be carried by the water flow can enter the filter bin 132 through the first filter screen 1321, and some impurities are precipitated in the filter bin 132, so that the waste can be classified again, so as to facilitate the pollution-free treatment of solid waste.

[0029] In a specific embodiment, the filter chamber 132 is further provided with a water outlet joint and a sewage discharge joint, the water outlet joint is provided at a position higher than the sewage discharge joint, and the water outlet joint is used to connect to the water inlet end of the water pump 133. It can be understood that the provision position of the water outlet joint is conducive to the precipitation of the liquid in the filter chamber 132, thereby improving the utilization rate of the liquid in the filter chamber 132.

[0030] Specifically, the water outlet joint is communicated with the first water inlet 1331 .

[0031] It should also be noted that in order to improve the uniformity of the particle size of the solid waste, the crushing device 120 is preferably a double-roll crushing mechanism.

[0032] Optionally, the crushing device 120 may also be a hammer crushing mechanism or a hammer crushing mechanism and a double-roll crushing mechanism used in combination.

[0033] See also Figure 1 In a specific embodiment, the sewage discharge structure includes a sewage discharge hole 1312 formed on the side wall of the cleaning chamber 131 and a guide groove 1313 arranged relative to the sewage discharge hole 1312, and the guide groove 1313 can guide the sewage discharged from the sewage discharge hole 1312 to be discharged into the filtering chamber 132.

[0034] It can be understood that the purpose of setting the drain hole 1312 is to allow the liquid to carry a portion of substances with lower density and soluble substances to achieve preliminary classification of solid waste. The setting of the guide groove 1313 expands the flow rate and flow of the liquid, reduces the risk of clogging of the drain hole 1312, and facilitates timely cleaning of the drain hole 1312.

[0035] Specifically, there is a distance between the drain hole 1312 and the bottom surface of the cleaning chamber 131, thereby reducing the flow of denser substances into the first filter screen.

[0036] Furthermore, there are multiple drain holes 1312 , and the multiple drain holes 1312 are arranged in an array, and the outer dimensions of the drain holes 1312 gradually increase upwards.

[0037] It can be understood that after the cleaning water is introduced into the crushed solid waste particles, the substances with higher density are in the lower part of the solution, and the solid waste with lower density floats on the upper part of the solution or in the solution. Therefore, the setting of the external dimensions or diameter size of the drain hole 1312 improves the classification efficiency of the solid waste and reduces the solid waste with larger mass entering the first filter 1321.

[0038] Further, in a specific embodiment, the sewage discharge structure further includes a gate 1314; A limiting guide groove 1315 is provided on one side of the cleaning chamber 131 close to the drain hole 1312, and the gate 1314 can slide relative to the limiting guide groove 1315; The gate 1314 is provided with a conducting hole 1316 corresponding to the drain hole 1312 , and the conducting hole 1316 cooperates with the drain hole 1312 .

[0039] It is understandable that when the sewage hole 1312 needs to be closed, the conducting hole 1316 provided on the gate 1314 corresponding to the sewage outlet can reduce the moving stroke of the gate 1314, improve work efficiency and reduce energy consumption.

[0040] It can also be understood that when the sewage in the filter chamber 132 needs to be statically precipitated or discharged in one direction, the gate 1314 needs to be used to block the sewage outlet to prevent the incoming water from turbidity of the sewage in the filter chamber 132.

[0041] In a specific embodiment, after the gate is closed, the precipitated sewage is sent into the cleaning tank 131 through the first water inlet 1331 by using a water pump 133 for recycling.

[0042] Furthermore, an electromagnetic suction cup 1318 is installed in the cleaning chamber 131, and the electromagnetic suction cup 1318 is used to absorb the magnetic conductive material in the solid waste particles, so as to further realize the reclassification of the solid waste particles.

[0043] See also Figures 1 to 3 , in a preferred embodiment of the present invention, the automatic solid waste processing equipment 100 further includes a frame 110 and a sorting device; The cleaning chamber 131 can move in a first direction V1 relative to the frame 110; The sorting device includes a vibration plate 141 and a driving assembly 142, wherein the driving assembly 142 is fixed to the frame 110, and the driving assembly 142 can drive the vibration plate 141 to reciprocate relative to the frame 110 in a second direction V2; The vibration plate 141 is provided with a limiting rib 1411 , and the bottom of the cleaning chamber 131 is provided with a limiting groove 1317 , and the limiting groove 1317 and the limiting rib 1411 can cooperate with each other in limiting manner in the second direction V2 .

[0044] It is understandable that after the cleaning bin 131 is placed on the vibration plate 141, the limiting groove 1317 can cooperate with the limiting rib 1411, so that the vibration plate 141 drives the cleaning bin 131 to move back and forth under the drive of the driving assembly 142. At this time, the solid waste particles in the cleaning bin 131 can also vibrate accordingly, so that the solid waste particles are further divided into layers or zones according to density.

[0045] In a specific embodiment, two electromagnetic suction cups 1318 arranged along the vibration direction (ie, the second direction V2) are installed in the cleaning chamber 131, and the electromagnetic suction cups 1318 are used to absorb the magnetic conductive material in the solid waste particles.

[0046] The width of the limiting groove 1317 is greater than the width of the limiting rib 1411, and the side wall of the limiting groove 1317 is conductively matched with the limiting rib 1411 through the elastic probe 1412. When the vibration plate 141 drives the cleaning chamber 131 to move back and forth, the side wall of the limiting groove 1317 is intermittently conductively connected with the limiting rib 1411.

[0047] Specifically, when the vibration plate 141 moves in the opposite direction of the second direction V2, the limiting groove 1317 and the limiting rib 1411 are disconnected from the power supply, and at this time, the electromagnetic suction cup 1318 in the opposite direction of the second direction V2 can generate magnetism; When the vibration plate 141 moves toward the positive direction of the second direction V2, the limiting groove 1317 and the limiting rib 1411 are disconnected from the power supply. At this time, the electromagnetic suction cup 1318 in the positive direction of the second direction V2 can generate magnetism.

[0048] It can be understood that the elastic probe 1412 is mainly provided to provide signal feedback.

[0049] It also needs to be explained that when the vibration plate 141 moves in the opposite direction of the second direction V2, the cleaning chamber 131 also moves with the vibration plate 141. However, due to inertia, most of the solid waste particles in the cleaning chamber 131 will still stay in the positive direction of the second direction V2. At this time, there are fewer metal waste particles in the cleaning chamber 131 in the opposite direction of the second direction V2. At this time, starting the electromagnetic suction cup 1318 on the side with fewer metal waste particles can make the magnetic metal particles adsorbed by the electromagnetic suction cup 1318 have higher purity and less impurities.

[0050] It can also be understood that during the reciprocating motion of the vibrating plate of the cleaning chamber 131, the magnetic conductive material is adsorbed in different directions. This method can make full use of the particle movement caused by the vibration, so that each electromagnetic suction cup can adsorb more magnetic conductive particles at its best time, thereby improving the overall separation efficiency.

[0051] For example, in the recycling of metal waste particles, if the doped metal is iron and other non-magnetic metals, the technical solution of this embodiment can achieve the separation of the two. Optionally, the operator can choose to manually separate other non-magnetic metals to other silos. It should also be noted that the cleaning bin 131 can move relative to the frame 110 in the first direction V1, which can be driven by humans or driven by the motor 1421. Specifically, those skilled in the art can make corresponding settings according to the specific application scenario and volume.

[0052] Optionally, a roller is provided at the bottom of the cleaning chamber 131 to reduce the driving force of the cleaning chamber 131. Further, the driving assembly 142 may be a driving cylinder, an electric push rod, or a cylinder connecting rod 1423 assembly.

[0053] Specifically, the frame 110 is provided with a protruding structure, and the vibration plate 141 is provided with a sliding groove, and the sliding groove is slidably matched with the protruding structure.

[0054] In a specific embodiment, the driving assembly 142 includes a motor 1421, a crank member 1422 and a connecting rod 1423. The motor 1421 is fixed to the frame 110. The motor 1421 can drive the crank member 1422 to rotate. One end of the connecting rod 1423 is rotationally matched with the end of the crank member 1422, and the other end of the connecting rod 1423 is rotationally matched with the vibration plate 141, thereby driving the vibration plate 141 to move back and forth.

[0055] It is understood that in the driving mechanism composed of the motor 1421, the crank member 1422 and the connecting rod 1423, the connecting rod 1423 can drive the vibration plate 141 to slide back and forth at a non-uniform speed, thereby further facilitating the stratification or partitioning of the solid waste according to mass and density. It is also understood that after the solid waste particles are stratified or partitioned, the staff can reclassify the solid waste particles by using tools or manual operation.

[0056] Furthermore, the tool used by the staff may be a rake or a mechanical arm. It is understandable that the rake or the mechanical arm is used to classify particles with lighter mass or density floating on the upper layer of the solid waste particles, thereby further achieving the classification of solid waste.

[0057] Optionally, the tool used by the staff is an electromagnetic suction cup 1318, and the electromagnetic suction cup 1318 is used to absorb the magnetic metal particles in the solid waste.

[0058] See also Figure 3 In a specific embodiment, the number of the cleaning chambers 131 is at least two; when one cleaning chamber 131 moves to the vibration plate 141 , the other cleaning chamber 131 can be placed under the crushing device 120 .

[0059] It can be understood that the two cleaning bins 131 are beneficial to the continuous operation of the crushing device 120 , thereby improving the working efficiency of the automatic solid waste processing equipment 100 .

[0060] Specifically, see Figure 4 The solid waste automatic processing equipment 100 has a loading station 101, a cleaning and screening station 102 and a material unloading and screening station 103; The upper bin station 101 is used to place the cleaning bin 131 to be used. When the cleaning bin 131 located at the cleaning and screening station 102 is moved to the unloading and screening station 103 , the cleaning bin 131 of the upper bin station 101 can be placed in the cleaning and screening station 102 .

[0061] See also Figures 1 to 5 , the technical solution of the present invention also proposes a solid waste automatic treatment method, which is applied to any of the solid waste automatic treatment equipment 100 described above; The method comprises the steps of: S1. Put the cleaning bin 131 into the cleaning position, start the crushing device 120 and the water pump 133, put solid waste into the feeding port 121, and inject water into the cleaning bin 131 through the water pump; the light-density waste particles in the cleaning bin 131 pass through the sewage discharge structure and the first filter screen 1321 and enter the filtering bin 132; the solid particles in the cleaning bin 131 pass through the sewage discharge structure and are blocked by the first filter screen 1321; the heavy-density waste particles in the cleaning bin 131 remain in the cleaning bin 131; S2. When the waste particles in the cleaning bin 131 exceed a certain value, the crushing device 120 and the water pump 133 are stopped; and the cleaning bin 131 is placed on a vibration plate; S3, energize the electromagnetic chuck 1318; the electromagnetic chuck 1318 can absorb the magnetic metal particles when energized; S4. Start the driving assembly to drive the cleaning bin 131 to vibrate, so that the solid waste particles in the cleaning bin 131 are divided into layers or zones according to density.

[0062] Further, after the garbage is put in, it is determined whether the water level of the filter chamber 132 is higher than the first preset position; wherein, the water level of the filter chamber 132 is determined by a water level sensor; If not, the water pump 133 pumps water through the second water inlet 1332 and discharges the water to the cleaning chamber 131 through the water outlet 1334; If yes, the water pump 133 draws water from the filtering chamber 132 through the first water inlet 1331 , and discharges the water to the cleaning chamber 131 through the water outlet 1334 .

[0063] Specifically, the sewage in the filter chamber 132 is filtered through the first filter screen 1321 to remove most of the solid particles; the gate 1314 is closed, and the filtered sewage is precipitated in the filter chamber 132, and the liquid above the solid precipitate is sent to the cleaning chamber 131 through the first water inlet 1331 to achieve recycling and recovery of the liquid.

[0064] It should be explained that the first preset position is the position where the first water inlet 1331 is connected to the filter chamber 132 .

[0065] It is understandable that before the liquid is fed into the cleaning chamber 131 , the gate 1314 is closed in order to prevent the water discharged from the sewage outlet from entering the filtering chamber 132 and muddying the liquid.

[0066] Furthermore, an electromagnetic suction cup 1318 is installed at the bottom of the cleaning bin 131. When the solid waste particles fall into the electromagnetic suction cup 1318 in the cleaning bin 131, the magnetic metal in the solid waste particles can be adsorbed, thereby further realizing the secondary classification of the solid waste.

[0067] Specifically, the solid waste automatic processing equipment 100 further includes a sorting device, which includes a vibration plate 141 and a driving assembly 142. After the solid waste particles in the cleaning bin 131 are flushed by the water pump 133 for a preset time, the staff moves the cleaning bin 131 to the vibration plate 141; When the vibration plate 141 is started, the solid waste particles in the cleaning chamber 131 are shaken back and forth, so that the solid waste can be reclassified so that the non-magnetic particles and the magnetic conductive materials are layered or partitioned.

[0068] Furthermore, when the water inlet of the water pump 133 cannot extract the liquid in the filter chamber 132 , the discharge port of the filter chamber 132 is opened to discharge the sewage in the filter chamber 132 .

[0069] Optionally, the sewage discharged from the filter tank 132 can be classified and recovered again through electromagnetic adsorption, filtration or sedimentation.

[0070] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
