Description

Technical Field

[0001] The present application relates to the technical field of solid waste treatment, and in particular to a solid waste classification and treatment system. Background Art

[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, consumption, life and other activities. Classification and treatment can reduce the consumption of land resources.

[0003] Fixed waste includes plastic and iron waste, etc. In the process of solid waste treatment, existing devices generally need to extrude plastics before transportation for the convenience of transportation. However, it is not easy to select iron materials before extrusion, so that the iron waste cannot be recycled in time to utilize its residual value, which reduces the treatment effect and damages the extrusion equipment, reducing the treatment efficiency. Summary of the invention

[0004] In order to improve processing efficiency, the present application provides a solid waste classification and processing system.

[0005] The present application provides a solid waste classification and treatment system, which adopts the following technical solutions: A solid waste classification and processing system comprises a machine body, an extrusion mechanism arranged on the machine body and used for extruding plastic, and a removal mechanism for removing iron waste is also arranged on the machine body, and the removal mechanism comprises: A containing box, which is arranged on the machine body and is used to contain solid waste and is provided with a material passage hole for the solid waste to pass through; Two magnet plates, the tops of which are arranged at the bottom of the containing box and are arranged obliquely, and the distance between the tops of the two magnet plates is greater than the distance between the bottoms; A control component is arranged on the containing box and is used to place fixed waste after closing the material passing hole, or to open the material passing hole and make the fixed waste fall to the two magnet plates to move and make the iron waste adsorbed on the magnet plates, and at the same time make the solid waste evenly spread and fall to the extrusion mechanism to be extruded; The removal component is arranged on the containing box and is used for removing the iron waste on the two magnet plates and collecting them.

[0006] By adopting the above technical solution, the fixed waste is inverted into the holding box for placement, the control component is started to open the material passage hole, and the solid waste in the holding box falls downward onto the two magnet plates. During the movement, the two magnet plates are used to adsorb iron waste, and the plastic falls downward onto the extrusion mechanism for extrusion. After the solid waste in the holding box is transported, the control component closes the holding box, and the solid waste continues to be inverted into the holding box. At the same time, the removal component is started to remove the iron waste adsorbed on the two magnet plates, and then the above process is repeated.

[0007] By moving the solid waste on the two magnet plates, the two magnet plates are used to absorb the iron waste, and finally the iron waste is removed and collected by removing the components, so that the magnet plates can better absorb the iron waste, so that the iron waste can be recycled in time and its residual value can be utilized, which improves the treatment effect, and also reduces the probability of damaging the extrusion equipment and reduces the treatment efficiency. At the same time, the two magnet plates are in an inclined state so that the solid waste can slow down and move on the two magnet plates, which improves the removal effect of the iron waste, and also allows the plastic to be evenly flattened before entering the extrusion mechanism, which improves the extrusion effect of the extrusion mechanism, thereby improving the treatment effect and efficiency.

[0008] Optionally, the control component includes: A control panel, slidably disposed on the containing box and used to control the closing or opening of the material passage hole; A control component is used to drive the control panel to move.

[0009] By adopting the above technical solution, the control component starts to drive the control plate to move horizontally back and forth, thereby realizing the opening or closing of the material passage hole.

[0010] Optionally, the removal component includes: A sliding frame is horizontally slidingly arranged on the machine body; Two scrapers are arranged on the sliding frame and used for scraping iron waste on the two magnet plates; A collecting box, which is arranged on the sliding frame and is located below the two scrapers and is used to collect the fallen iron waste; The telescopic member is used to drive the sliding frame to move the two scrapers and the collecting box to remove the iron waste, or to move the two scrapers and the collecting box to the outside of the two magnet plates.

[0011] By adopting the above technical solution, the telescopic part starts to drive the sliding frame to move, and the sliding frame drives the two scrapers and the collecting box to move simultaneously. After the two scrapers come into contact with the magnet plate, they scrape off the adsorbed iron waste, and the fallen iron waste falls down into the collecting box for collection, thereby achieving the purpose of removing the iron waste on the magnet plate, and then the telescopic part drives the two scrapers and the collecting box to move back to the outside of the two magnet plates. When the scrapers move back, they can continue to scrape off the iron waste on the magnet plate. Therefore, the iron waste on the magnet plate can be removed without interfering with the passage of waste, thereby further improving the processing efficiency and effect.

[0012] The iron waste in the collection box is cleaned in time, thereby improving the collection effect of the iron waste and reducing the probability of iron falling from the collection box; at the same time, the collection box moves simultaneously with the movement of the scraper, so that the iron waste can gradually fall into the collection box, reducing the probability of iron waste falling in one place and falling from the collection box, further improving the removal effect of the iron waste, that is, further improving the processing efficiency and effect.

[0013] The movement of the scraper can also make the fixed waste stuck between the two magnet plates fall into the collection box for collection. Finally, the staff can clean it up in time when cleaning the collection box, thereby further reducing the adverse effects of the stuck fixed waste on subsequent waste treatment and further improving the treatment efficiency and effect.

[0014] Optionally, a control box electrically connected to the two magnet plates is provided on the machine body, and the control box controls the magnet plates to be powered on to generate magnetism for adsorbing iron waste, or controls the magnet plates to be powered off to cause the iron waste to fall; the collection box is detachably arranged on the sliding frame.

[0015] By adopting the above technical solution, before the solid waste passes through the magnet plate, the control box controls the magnet plate to be energized to form magnetism, so that the iron waste can be better adsorbed. After the scraper moves to scrape off the iron waste, the control box controls the magnet plate to be powered off, so that the iron material still remaining on the magnet plate continues to fall into the collection box. At the same time, when the scraper moves back, the remaining iron material can continue to be cleaned. Compared with the ordinary magnet structure, the magnetization effect of power supply is more stable and lasting, and the power can be cut off during cleaning, thereby further improving the cleaning effect and improving the processing efficiency and effect.

[0016] The collecting box and the sliding frame are detachable, so that it is convenient to remove the collecting box and clean the iron waste. After cleaning, the collecting box can be fixedly mounted on the sliding frame, thereby further improving the processing efficiency and effect.

[0017] Optionally, the two magnet plates are rotatably arranged at the bottom of the containing box via a rotating shaft, and a torsion spring connected to the containing box and the magnet plates and used for maintaining the position of the magnet plates is sleeved on the rotating shaft.

[0018] By adopting the above technical solution, the magnet plate maintains a stable state through the torsion spring, so when waste falls onto the magnet plate, a certain impact force will be generated, and the solid waste is disorderly when accumulated in the storage box, and the volume of the solid waste is different. The above factors make the impact force of the waste on the magnet plate change in real time, causing the magnet plate to swing back and forth slightly. The reciprocating swing can make the fixed waste form a certain vibration effect, so that the iron material can fall down and be adsorbed by the magnet plate, thereby improving the adsorption effect of the iron waste.

[0019] At the same time, the magnet plate is movable within a certain range, so the distance between the bottoms of the two magnet plates can be designed to be small, so that most of the waste can pass through. When encountering larger waste, the waste can push the two magnet plates away from each other and pass through. The smaller size can further improve the adsorption effect on iron waste, thereby further improving the processing efficiency and effect.

[0020] At the same time, when larger solid waste is stuck on the two magnet plates, the two magnet plates are pushed away from each other, so that the two scrapers do not contact the two magnet plates after just entering between the two magnet plates, and the iron waste cannot be cleaned. The two scrapers move and push the stuck waste to fall. When the scraper moves to the other end of the magnet plate, the control box controls the magnet plate to cut off the power, so that the two magnet plates can better clean the iron waste on the magnet plates after moving back, thereby improving the cleaning effect of the iron waste and improving the processing efficiency and effect.

[0021] Optionally, a plurality of scrapers are slidably arranged in the receiving box for scraping off waste adhering to the side wall of the receiving box, and the scrapers are connected to the sliding frame.

[0022] By adopting the above technical solution, when fixed waste is placed in the storage box, it is easy to adhere to the inner wall of the storage box under the squeezing effect of other waste. Over time, the space in the storage box becomes smaller and the waste cannot be processed in time, thereby reducing the discharge efficiency and effect.

[0023] When the telescopic part drives the sliding frame to move, the sliding frame drives multiple scrapers to move. The scrapers are used to scrape off the waste adhering to the storage box, so that the waste falls downward to the bottom of the storage box for temporary storage. At this time, the material passage hole is in a closed state, so that it is convenient for the next waste treatment to be carried out in time. After cleaning is completed, the scraper moves back under the action of the sliding frame, so that the scraper is away from the storage box, thereby reducing the adverse interference of the scraper on the waste placed in the storage box, and further improving the treatment efficiency and effect.

[0024] Optionally, the extrusion mechanism includes: Two crushing rollers are rotatably arranged on the machine body and are used to squeeze the plastic and crush fragile waste materials such as soil and stones to form waste particles; A conveyor belt is arranged on the machine body and is evenly provided with a plurality of screening holes for waste particles to pass through and is used to convey the extruded plastic; A collecting box, disposed on the machine body and used to collect waste particles passing through the screening holes; A guide plate, which is arranged on the machine body and extends to the inner side of the conveyor belt and is used to guide the waste particles passing through the screening holes to the collection box for collection; The extrusion assembly is arranged on the machine body and is used for extruding the plastic conveyed on the conveyor belt.

[0025] By adopting the above technical solution, the fixed waste also contains fragile waste such as soil and stones, so it is necessary to screen out the plastic and fragile waste, so as to further improve the processing efficiency and effect.

[0026] The waste passing through the two magnet plates falls onto the two crushing rollers. The two crushing rollers rotate and squeeze the plastic, thereby flattening waste such as plastic bottles, and at the same time crushing fragile waste such as soil and stones to form granular waste particles, which fall down onto the conveyor belt. The waste particles fall downward through the screening holes and are moved to the collection box under the guidance of the guide plate for collection. The flattened waste can be transported to the extrusion assembly through the conveyor belt and then extruded centrally, so as to realize the classification and treatment of various wastes.

[0027] The crushing rollers are used to crush the fragile waste and squeeze and flatten the plastics. Then the conveyor belt is used to screen the waste particles and convey the flattened plastics, which improves the convenience and effect of screening the two types of waste, thereby greatly improving the processing efficiency and effect. At the same time, the waste particles fall into the collection box under the action of the guide plate after passing through the screening holes on the upper layer of the conveyor belt, without passing through the screening holes on the lower layer of the conveyor belt, thereby reducing the probability of waste particles accumulating on the inner side of the conveyor belt and improving the processing efficiency and effect.

[0028] Optionally, the extrusion assembly includes: A squeeze box, which is arranged on the machine body and is used to collect the plastic conveyed on the conveyor belt; An extrusion plate is slidably disposed on the extrusion box and is used to re-extrude the plastic; The extrusion member is used to drive the extrusion plate to move.

[0029] By adopting the above technical solution, the extrusion member starts to drive the extrusion plate to move, and the extrusion plate moves to extrude and flatten the plastic, thereby reducing the space occupied by the plastic and facilitating transportation.

[0030] Optionally, the extrusion box is provided with an output port for outputting the extruded plastic, and the extrusion box is provided with an opening and closing component for controlling the opening and closing of the output port, and the opening and closing component includes: An opening and closing door, rotatably arranged on the extrusion box and used for closing or opening the output port; The opening and closing parts are used to drive the opening and closing doors to rotate.

[0031] By adopting the above technical solution, when discharge is required, the opening and closing part drives the opening and closing door to open the output port, so the extrusion part starts to push the extrusion plate to move, and the movement of the extrusion plate can push the extruded plastic to be discharged through the output port for discharge, and then the extrusion plate is driven to move back, and finally the opening and closing part drives the opening and closing door to close the output port, so that the plastic feeding and extrusion can continue, thereby improving the processing efficiency and effect.

[0032] Optionally, the crushing roller is provided with a pointed cone for striking fragile waste materials such as soil and stones.

[0033] By adopting the above technical solution, it is easier to break fragile waste materials such as soil and stones, further improving the processing efficiency and effect.

[0034] In summary, the present application includes at least one of the following beneficial technical effects: 1. Two magnet plates are used to adsorb iron waste, and finally the iron waste is removed and collected by removing the components, so that the magnet plate can better adsorb the iron waste, so that the iron waste can be recycled in time and its residual value can be utilized, which improves the processing effect and reduces the probability of damaging the extrusion equipment, reducing the processing efficiency and effect.

[0035] 2. The two magnetic plates are tilted so that the solid waste can slow down and move on the two magnetic plates, which improves the removal effect of iron waste. At the same time, the plastic can be evenly flattened before entering the extrusion mechanism, which improves the extrusion effect of the extrusion mechanism, thereby improving the processing effect and efficiency.

DETAILED DESCRIPTION

[0038] The present application is described in further detail below.

[0039] The embodiment of the present application discloses a solid waste classification and processing system.

The removal mechanism 2 is used to remove the iron material in the solid waste, and then the solid waste continues to move to the extrusion mechanism 5 for extrusion.

[0041] The removal mechanism 2 includes a receiving box 21, two magnet plates 22, a control component 3, and a removal component 4. The receiving box 21 is fixedly mounted on the body 1 and is in a vertical state. The top of the receiving box 21 is open and convenient for placing solid waste. A material passage hole 23 for passing solid waste is formed at the bottom of the receiving box 21; two mounting plates 26 are fixedly mounted at both ends of the receiving box 21 and close to one side of the bottom of the receiving box 21, and the bottoms of the two mounting plates 26 extend vertically downward to the bottom of the receiving box 21; the two magnet plates 22 are rotatably mounted on the bottom of the receiving box 21 through two rotating shafts and are mirror-set with respect to the material passage hole 23, and the axis of the rotating shaft is parallel to the length direction of both the receiving box 21 and the material passage hole 23.

[0042] The solid waste falling through the material passage hole 23 falls onto the two magnet plates 22, on which electric wires for powering are fixedly installed, and a control box electrically connected to the electric wires is fixedly installed on the outer wall of the receiving box 21, and the control box is used to control the two magnet plates 22 to power on and generate magnetism, thereby achieving adsorption of iron waste in the waste, or the control box controls the two magnet plates 22 to cut off power, thereby releasing the adsorption force on the iron waste.

[0043] A torsion spring is fixedly installed on the bottom of the containing box 21 and is sleeved on the rotating shaft and fixedly connected to the magnet plate 22. The torsion spring is used to maintain the state of the magnet plate so that the two magnet plates 22 are inclined and the distance between the tops is greater than the distance between the bottoms. The two magnet plates 22 extend between the two mounting plates 26 and abut against the side walls on the opposite side of the two mounting plates 26. Solid waste can be evenly distributed when it falls on the two inclined magnet plates 22, and the two mounting plates 26 are used to seal the space at both ends of the two magnet plates 22.

[0044] Reference Figure 2 and Figure 3 The control component 3 is arranged on the receiving box 21 and is used to place fixed waste after closing the material hole 23, or to open the material hole 23 and allow the fixed waste to fall onto the two magnet plates 22 to move, so that the iron waste is adsorbed on the magnet plates 22, and the solid waste is evenly distributed on the two magnet plates 22. The control component 3 includes a control board 31 and a control member 32. The control board 31 is horizontally slidably mounted on the inner bottom wall of the receiving box 21, and the control board 31 is used to open or close the material hole 23; the control member 32 can be a cylinder or an electric push rod, and the control member 32 is fixedly mounted on the body 1 and the piston rod is fixedly connected to the control board 31, so as to realize the driving of the control board 31 to move.

[0045] The removal component 4 is arranged on the receiving box 21 and is used to remove the iron waste on the two magnet plates 22. The removal component 4 includes a sliding frame 41, two scrapers 42, a collecting box 43, and a telescopic member 44. The sliding frame 41 is horizontally slidably installed on the body 1 along the length direction of the receiving box 21; the two scrapers 42 are fixedly installed on the side wall of the sliding frame 41 close to the two magnet plates 22. The two scrapers 42 slide along the length direction of the receiving box 21 and penetrate on the mounting plate 26 close to the side of the sliding frame 41 and are located on the inner side of the two magnet plates 22. The two scrapers 42 are provided with a guide angle for squeezing the two magnet plates 22 and entering between the two magnet plates 22. The two magnet plates 22 are pressed against the two scrapers 42 under the action of the torsion spring, and the scrapers 42 move to scrape off the iron waste adhered to the magnet plates 22.

[0046] When the scraper 42 moves from one end of the two magnet plates 22 to the other end, the control box controls the two magnet plates 22 to cut off the power, thereby releasing the adsorption force on the iron waste. The two scrapers 42 move back to continue scraping the iron waste on the magnet plates 22. Finally, the control box controls the two magnet plates 22 to be energized to generate magnetism for adsorbing the iron waste.

[0047] A horizontal supporting plate 46 is fixedly mounted on the sliding frame 41 and below the two mounting plates 26 and the two magnet plates 22. The collecting box 43 is detachably mounted on the upper surface of the supporting plate 46 by means of a clamp or screws. Both ends of the collecting box 43 and the two scrapers 42 are flush, so that the iron material scraped off by the scrapers 42 can fall into the collecting box 43 in time for collection. At the same time, the collecting box 43 can be removed for cleaning, which improves the collection effect of the iron waste and reduces the probability of the iron waste accumulating in one place.

[0048] The telescopic member 44 may be a cylinder or an electric push rod, and the telescopic member 44 is fixedly mounted on the machine body 1 and the piston rod is connected to the sliding frame 41. The telescopic member 44 is started to drive the sliding frame 41 to move, and the sliding frame 41 moves to drive the two scrapers 42 and the collection box 43 to move, so as to remove the iron waste adhering to the magnet plate 22, and then the telescopic member 44 drives the sliding frame 41 to move back, so that the two scrapers 42 and the collection box 43 are moved to the outside of the two magnet plates 22, so as not to interfere with the passage of fixed waste.

[0049] Two scrapers 47 are provided on the outer wall of the storage box 21 so as to slide along the sliding direction of the sliding frame 41. The two scrapers 47 respectively abut against the inner walls of the two storage boxes 21. Both scrapers 47 are connected to the sliding frame 41. When the sliding frame 41 drives the two scrapers 42 to scrape off the iron waste, the two scrapers 47 can also clean the inner wall of the storage box 21, so that the adhered solid waste can fall into the storage box 21 for storage, so as to facilitate timely treatment of the waste the next time.

[0050] Reference Figure 1 and Figure 2 The extrusion mechanism 5 includes two crushing rollers 51, a conveyor belt 52, a collecting box 53, a guide plate 54, and an extrusion assembly 6. The two crushing rollers 51 are rotatably mounted on the machine body 1 and the axes are parallel to the length direction of the containing box 21. The two crushing rollers 51 are evenly provided with a plurality of sharp cones 55 for impacting and crushing fragile waste materials such as soil and stones. A synchronous motor for driving the two crushing rollers 51 to rotate in opposite directions at the same time is fixedly mounted on the machine body 1. The two crushing rollers 51 rotate in opposite directions to extrude the plastic, and the sharp cones 55 impact and crush the fragile waste materials to form waste particles.

[0051] The conveyor belt 52 is installed on the machine body 1 and extends from the bottom of the two crushing rollers 51 along the axis of the crushing rollers 51 to the outside of the crushing rollers 51. A plurality of screening holes for waste particles to pass through are evenly opened on the conveyor belt 52; the collecting box 53 is placed on the machine body 1 or on the ground and is located below the conveyor belt 52; the guide plate 54 is in a broken line shape and is fixedly installed on the machine body 1. The highest point of the guide plate 54 passes through the inner side of the conveyor belt 52 and extends obliquely downward to both sides of the conveyor belt 52. The extrusion assembly 6 is located on one side of the collecting box 53 and is used to extrude plastic.

[0052] The waste particles and the flattened plastic fall downward onto the conveyor belt 52 for transportation. During the transportation process, the waste particles fall downward through the screening holes onto the guide plate 54. The guide plate 54 guides the waste particles into the collecting box 53 for collection. At the same time, some waste particles can also fall downward through the outside of the guide plate 54 into the collecting box 53 for collection. The flattened plastic continues to move and falls into the extrusion assembly 6. The extrusion assembly 6 is started to extrude and stack the plastics together.

[0053] Reference Figure 1 and Figure 4 The extrusion assembly 6 includes an extrusion box 61, an extrusion plate 62 and an extrusion piece 63. The extrusion box 61 is fixedly mounted on the machine body 1 or the ground. The extrusion box 61 is located below the conveyor belt 52 and has a feed port at the top for the flattened plastic to enter. The extrusion plate 62 is horizontally slidably mounted on the inner wall of the extrusion box 61. The extrusion plate 62 is used to extrude the plastic again, which greatly reduces the space occupied by the plastic. The extrusion piece 63 is an oil cylinder or an electric push rod. The extrusion piece 63 is fixedly mounted on the machine body 1, and the piston rod of the extrusion piece 63 is horizontally penetrated through the extrusion box 61 and fixedly connected to the extrusion plate 62.

[0054] An output port for the extruded plastic to pass through is provided on the side wall of the extrusion box 61 away from the extrusion member 63. An opening and closing assembly 7 for controlling the opening and closing of the output port is provided on the extrusion box 61. The opening and closing assembly 7 includes an opening and closing door 71 and an opening and closing member 72. The opening and closing door 71 is rotatably mounted on the extrusion box 61 and is used to open or close the output port. The opening and closing member 72 is an oil cylinder or an electric push rod. One end of the opening and closing member 72 is rotatably mounted on the extrusion box 61 and the piston rod is rotatably connected to the opening and closing door 71, thereby driving the opening and closing door 71 to rotate and close or open the output port.

[0055] After the plastic extrusion is completed, the opening and closing member 72 starts to drive the opening and closing door 71 to open, and the extrusion member 63 starts to drive the extrusion plate 62 to push the plastic out through the output port, and then the plastic is transported, reducing the space occupied by the plastic and improving the processing efficiency and effect. Finally, the opening and closing member 72 starts to drive the opening and closing door 71 to rotate and close the output port, and then the next plastic extrusion is carried out.

[0056] The working principle of the embodiment of the present application is as follows: The fixed waste is placed in the receiving box 21. After the receiving box 21 is full, the control part 32 controls the material passage hole 23 to open, and the solid waste falls downward onto the two magnet plates 22 to move. During the movement, the two magnet plates 22 are used to absorb the iron material, and the solid waste is also evenly spread on the two magnet plates 22. Then the solid waste falls downward onto the two crushing rollers 51. The two crushing rollers 51 flatten the plastic, and the pointed cone 55 crushes the fragile waste such as soil and stones to form waste particles. The flattened plastic and the waste particles fall downward onto the conveyor belt 52. The waste particles fall downward into the collecting box 53 for collection. The flattened plastic is conveyed to the extrusion box 61 for temporary storage. The extrusion part 63 drives the extrusion plate 62 to extrude the plastic, thereby reducing the space occupied by the plastic. After the extrusion is completed, the extruded plastic is output through the output port, thereby improving the processing efficiency and effect.

[0057] After the fixed waste in the receiving box 21 is output, the control part 32 drives the material passage hole 23 to be closed, and the telescopic part 44 starts to drive the two scrapers 42 and the collecting box 43 to approach the two magnet plates 22. The two scrapers 42 are used to scrape off the iron waste on the two magnet plates 22 and then drop it into the collecting box 43 for collection. At the same time, the two scrapers 47 move to scrape off the solid waste adhering to the receiving box 21. The telescopic part 44 drives the two scrapers 42 and the collecting box 43 to move back to the outside of the two magnet plates 22, and the collecting box 43 is removed for cleaning, thereby realizing the cleaning of the two magnet plates 22, further improving the removal effect of the iron waste, and improving the processing efficiency and effect.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
