[0002] Biomedical plastic waste refers to discarded plastic materials generated during the production, packaging, use and processing of biomedical products. With the rapid development of the biomedical industry, a large amount of biomedical plastic waste has been generated. This type of waste has both the characteristics of plastic materials and potential biological hazards, and it is difficult to properly dispose of it using traditional garbage disposal methods.
[0003] When treating existing biomedical plastic waste, it is generally necessary to put the cleaned and disinfected waste into a crusher to break large pieces of waste into smaller pieces, thereby facilitating subsequent pyrolysis treatment. However, in the treatment of medical plastic waste, if metal waste is mixed in the plastic waste, it will affect the recycling quality of the plastic.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention facilitates the separation of metal waste from plastic waste through the coordination between structures such as a baffle, an electromagnet and a vibration component, thereby improving the processing efficiency of medical waste. The electromagnet is installed inside the baffle, so that after the crushed waste falls onto the baffle, the metal waste inside can be adsorbed onto the surface of the baffle under the action of the magnetic force of the electromagnet, and the gear is corrugated, so that the connecting column on the round rod drives the rotating shaft to move slightly back and forth along the trajectory of the guide groove, and then the rotating shaft drives the baffle to move, and the plastic waste on it can flow into the external collection box through the discharge port faster and more efficiently, so that the metal waste and plastic waste in the medical waste are separated conveniently, thereby improving the processing efficiency of medical waste.

When the limit plate moves, the convex rod is driven to slide along the trajectory of the arc groove, thereby causing the cylinder to rotate. The arc of the arc groove is twenty degrees. Therefore, after the arc groove rotates twenty degrees, the cross block and the cross groove can be used to drive the rotating shaft and the baffle thereon to rotate twenty degrees counterclockwise, so that one side of the baffle is abutted against the discharge port close to the waste box. The movement is stopped by the electromagnet, and the metal waste on the baffle loses its magnetic force and falls into the waste box along the inclined surface of the baffle, thereby facilitating the collection of the metal waste.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.
[0020] like Figures 1 to 9 As shown, the present invention provides an environmentally friendly treatment device for biomedical plastic waste, comprising a crushing box 1, a feeding port 2 is arranged on the top of the crushing box 1, a rotating shaft 3 is movably connected inside the crushing box 1, a baffle 4 is fixedly connected outside the rotating shaft 3, an electromagnet 5 is arranged inside the baffle 4, a motor 6 and an electronic telescopic rod 10 are respectively fixedly connected inside the two sides of the crushing box 1, a vibration component 7 and a moving component 8 are movably connected inside the crushing box 1 near the motor 6, a rotating component 9 is movably connected inside the crushing box 1 near the electronic telescopic rod 10, a waste box 12 is movably connected inside the crushing box 1, and discharge ports 13 are opened on both sides of the crushing box 1; The vibration assembly 7 includes a rotating drum 71, a gear 72 is fixedly connected to the outside of the rotating drum 71, a guide groove 73 is opened on the inner wall of the rotating drum 71, and a round rod 74 located inside the guide groove 73 is movably connected inside the crushing box 1; The moving assembly 8 includes a tooth plate 81, and both ends of the tooth plate 81 are movably connected to tooth blocks 82; The rotating assembly 9 includes a cylinder 91 , and two arc grooves 92 are formed in an annular manner on the surface of the cylinder 91 . One end of the electronic telescopic rod 10 is fixedly connected to a limiting plate 94 .
[0021] The above scheme is adopted: an electromagnet 5 is installed inside the baffle 4, so that after the crushed waste falls onto the baffle 4, the metal waste inside can be adsorbed to the surface of the baffle 4 under the action of the magnetic force of the electromagnet 5, and the gear 72 is corrugated, so that the connecting column on the round rod 74 drives the rotating shaft 3 to move slightly back and forth along the trajectory of the gear 72, and then the rotating shaft 3 drives the baffle 4 to move, and the plastic waste on it can flow into the external collection box through the discharge port 13 faster and more efficiently, so as to facilitate the separation of metal waste and plastic waste in medical waste, thereby improving the treatment efficiency of medical waste.
[0022] like Figure 3 , Figure 5 and Figure 8 As shown, the guide groove 73 is corrugated, and the outer wall of the round rod 74 is provided with two connecting columns that are movably engaged with the inside of the guide groove 73. A square plate 75 is fixedly connected to the middle of the outer wall of the round rod 74. A sliding groove for circumferentially limiting the square plate 75 is provided on the inner wall of the crushing box 1. The end of the round rod 74 away from the guide groove 73 is movably engaged with the rotating shaft 3, the output shaft end of the motor 6 is fixedly connected to the rotating drum 71, the gear 72 is meshed with the tooth plate 81, and springs 83 are fixedly connected to both ends of the tooth block 82. The tooth block 82 is elastically connected to the tooth plate 81 through the spring 83, and a button 11 located at one end of the tooth plate 81 is provided inside the crushing box 1.
[0023] The above scheme is adopted: through the design of spring 83, its function is that, since the motor 6 drives the rotating drum 71 and the gear 72 outside it to rotate continuously, therefore, when the gear 72 pushes the tooth plate 81 to move in the direction of the button 11 and meshes with the tooth block 82, the gear 72 continues to rotate at this time, and the tooth block 82 will be reset by the elastic force of the spring 83 in the gap of the rotation of the gear 72, so that the tooth plate 81 can remain stationary after abutting against the button 11, thereby ensuring the normal operation of the device.
[0024] like Figure 4 and Fig. 9 As shown, the arc groove 92 has an arc angle of twenty degrees, and the limit plate 94 is sleeved on the outside of the cylinder 91. The upper and lower ends of the inner wall of the limit plate 94 are fixedly connected with protruding rods 95, and the protruding rods 95 are movably clamped in the inside of the arc groove 92. The end of the cylinder 91 close to the rotating shaft 3 is fixedly connected with a cross clamping block 93, and the end of the rotating shaft 3 away from the motor 6 is provided with a cross groove adapted to the cross clamping block 93. The cross clamping block 93 is movable inside the cross groove of the rotating shaft 3. When the limit plate 94 moves, it drives the protruding rod 95 to slide along the trajectory of the arc groove 92 and rotates the cylinder 91 counterclockwise by twenty degrees. When the cylinder 91 rotates, the rotating shaft 3 is driven to rotate in the same direction through the cross clamping block 93.
[0025] The above scheme is adopted: when the limit plate 94 moves, the protruding rod 95 is driven to slide along the trajectory of the arc groove 92, thereby causing the cylinder 91 to rotate. The arc of the arc groove 92 is twenty degrees, so that after the arc groove 92 rotates twenty degrees, the cross block 93 can cooperate with the cross groove to drive the rotating shaft 3 and the baffle 4 thereon to rotate twenty degrees counterclockwise, so that one side of the baffle 4 abuts against the discharge port 13 close to the side of the waste box 12, and the movement is stopped by the electromagnet 5, so that the metal waste on the baffle 4 loses its magnetic force and falls into the waste box 12 along the inclined surface of the baffle 4, thereby facilitating the collection of the metal waste.
[0026] like Figure 5 and Figure 6 As shown, the baffle 4 rotates with the rotating shaft 3 as the axis. The baffle 4 is inclined in the initial state, and the inclination angle of the baffle 4 to the horizontal plane is ten degrees. The side of the crushing box 1 close to the waste box 12 is movably connected with an inclined block 14, and the bottom end of the inclined block 14 is inclined, and the top of the inclined block 14 abuts against one side of the baffle 4. The side of the inclined block 14 away from the baffle 4 is fixedly connected with a spring piece 15, and the inclined block 14 is elastically connected to the crushing box 1 through the spring piece 15. A slot identical to the discharge port 13 is provided on one side of the waste box 12, and the waste box 12 is connected to the crushing box 1 through the slot and the discharge port 13. A square groove for the baffle 4 to be flipped is provided inside the crushing box 1.
[0027] The above scheme is adopted: the inclined block 14 is abutted against the baffle 4, and its function is that after the baffle 4 is tilted, a gap will be left between one end of its top and the inner wall of the crushing box 1, and the design of the inclined block 14 can physically block the gap, thereby preventing plastic waste from entering the waste box 12 through the gap. The bottom end of the inclined block 14 is inclined, and its function is that when the baffle 4 is flipped, the inclined block 14 will be squeezed to shrink into the crushing box 1, and when the metal waste on the baffle 4 is collected, the baffle 4 will abut against the inclined surface of the inclined block 14 when it is reset, thereby facilitating the squeezing of the inclined block 14 into the crushing box 1, and then, through the design of the spring piece 15, after the baffle 4 contacts the abutment against the inclined block 14, the inclined block 14 will be reset under the action of the elastic force of the spring piece 15, and then abut against one end of the baffle 4 again.
[0028] The working principle and use process of the present invention are as follows: the operator starts the motor 6, so that the motor 6 drives the drum 71 and the gear 72 outside it to rotate, and then the gear 72 cooperates with the tooth plate 81, so that the moving assembly 8 moves toward the button 11 as a whole. When the tooth block 82 at one end of the tooth plate 81 away from the button 11 is meshed with the gear 72, at this time, one end of the tooth plate 81 abuts against the button 11, and the button 11 is pressed, so that the circuit inside the crushing box 1 is closed. At the same time, the controller inside the crushing box 1 will also transmit the electrical signal of the closed circuit to the circuit part where the electromagnet 5 is located, thereby driving the electromagnet 5 to operate; When the drum 71 rotates, the connecting column on the guide groove 73 will slide along the track of the gear 72. Since the inner wall of the crushing box 1 is provided with a slide groove for circumferentially limiting the round rod 74, the connecting column can only drive the guide groove 73 and the round rod 74 to do left and right reciprocating motion. At this time, one end of the round rod 74 is movably connected to the inside of the rotating shaft 3, so that the round rod 74 drives the rotating shaft 3 and the baffle 4 outside it to move while moving. Subsequently, the operator puts the medical waste into the crushing box 1 through the discharge port 2, and crushes the waste through the crushing box 1. Subsequently, the crushed waste falls onto the baffle 4, and the movement of the baffle 4 causes the crushed waste on it to vibrate. While the waste vibrates on the baffle 4, the metal waste will be adsorbed on the electromagnet 5 under the action of magnetic force, thereby separating the metal waste from the plastic waste. Subsequently, the plastic waste enters the external collection box through the discharge port 13 on one side of the crushing box 1, so as to facilitate the plastic waste to enter the next step of processing. When the crushing is completed, the operator starts the electronic telescopic rod 10, so that the electronic telescopic rod 10 pulls the limit plate 94 to move in the direction of the rotating shaft 3, and then the two protruding rods 95 on the inner wall of the limit plate 94 slide along the trajectory of the arc groove 92. Since the arc of the arc groove 92 is twenty degrees, after the protruding rod 95 slides, it can drive the cylinder 91 to rotate twenty degrees counterclockwise through the arc groove 92. Since the cross clamping block 93 is movably connected to the inside of the cross groove of the rotating shaft 3, when the cylinder 91 rotates, it can drive the rotating shaft 3 to rotate synchronously through the cross clamping block 93, and then the rotating shaft 3 drives the baffle 4 and the metal waste thereon to turn over; when the baffle 4 turns over twenty degrees, one end of it will abut against the discharge port 13 close to the waste box 12. Finally, the operator controls the motor 6 to flip through the information terminal, so that the motor 6 drives the rotating drum 71 and the gear 72 to flip, and then the tooth plate 81 moves in the direction away from the button 11 under the action of external force, and contacts the button 11. After the button 11 is released, the circuit inside the crushing box 1 will be disconnected again, and then the electrical signal will be transmitted to the electromagnet 5, so that the electromagnet 5 stops running. Subsequently, the metal waste on the baffle 4 loses the magnetic force of the electromagnet 5, and slides along the slope of the baffle 4, through the discharge port 13 and the groove on one side of the waste box 12, to the inside of the waste box 12, thereby facilitating the collection of the metal waste on the baffle 4.
