Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of harmless treatment devices, and in particular to a harmless treatment device for plastic containing drug residues. Background Technology
[0002] Drug-containing plastic waste disposal equipment is typically used to treat plastic waste that may contain drug residues due to contact with or storage of pharmaceuticals. The purpose of such equipment is to use certain technical means to ensure that these plastic wastes containing drug residues are treated safely and harmlessly, avoiding harm to the environment and human health.
[0003] Traditional high-temperature pyrolysis methods utilize industrial incinerators. In these incinerators, pesticide-containing plastic bottles and bags are fed into the incineration chamber. The high temperatures decompose most organic matter and pesticide components. The thermal decomposition temperature of most pesticides is between 200-600℃, where they are further oxidized into harmless substances such as CO2 and H2O. However, in practice, it has been found that excessive amounts of pesticide-containing plastics are added, leading to clumping and insufficient localized temperature. This results in incomplete decomposition of pesticide residues and plastics, producing volatile organic compounds (VOCs) or toxic intermediates, thus affecting the actual treatment effect. Utility Model Content
[0004] The technical problem this invention aims to solve is that existing methods sometimes result in excessive input of plastic containing drug residues, leading to accumulation and clumping. This causes the plastic to clump together during feeding, resulting in insufficient local temperature, incomplete decomposition of drug residues and plastic, and the generation of volatile organic compounds (VOCs) or toxic intermediate products, thus affecting the actual treatment effect.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a harmless treatment device for plastic containing drug residues, including an incinerator, an incineration chamber is opened on the inner wall of the incinerator, a furnace door is installed on the surface of the incinerator, an exhaust pipe is installed on the top of the incinerator, and a pretreatment device is provided on the surface of the incinerator, wherein the pretreatment device crushes the plastic to be incinerated by means of a treatment frame and blades.
[0006] The effect achieved by the above components is as follows: when using an incinerator to process plastic products containing drug residues, the incineration chamber is first started to generate high temperature inside the incineration chamber, and the furnace door is kept closed. Then, the plastic is added to the pretreatment device for crushing and finally enters the incineration chamber for incineration.
[0007] Preferably, the pretreatment device includes a treatment frame, which is connected to the combustion chamber of the incinerator. Two mounting rods are rotatably connected through the inner wall of the treatment frame. Several evenly distributed blades are fixedly connected to the arc surface of the mounting rods. The incinerator is rotatably connected to two connecting shafts. The arc surfaces of the two connecting shafts are respectively equipped with meshing gears. Sprockets are fixedly connected to the arc surfaces of the two mounting rods and the two connecting shafts. One of the mounting rods and the sprocket on the arc surface of one of the connecting shafts are meshed together by a chain.
[0008] The effect achieved by the above-mentioned components is that when plastic containing drug residues is treated harmlessly in an incinerator, it can better ensure the dispersion and breakage of plastic products, and it is less likely to clump together. This ensures that the plastic is heated evenly during incineration, guarantees the complete decomposition of drug residues and materials, and improves the treatment effect.
[0009] Preferably, a rotating shaft is mounted on the surface of the processing frame, wherein a baffle is rotatably connected to the arc surface of the rotating shaft.
[0010] The effect achieved by the above components is as follows: by setting the baffle, during the gap of crushing and incinerating the material, the baffle can be rotated along the arc surface of the rotating shaft to close the opening of the processing frame. At this time, the environment inside the incinerator can be kept relatively closed, so that the temperature is not prone to abnormal fluctuations.
[0011] Preferably, an operating handle is fixedly connected to one side surface of the baffle, wherein the operating handle improves the ease of use of the baffle.
[0012] The effect achieved by the above components is that, through the setting of the operating handle, the baffle can be operated more conveniently when rotating, and the opening and closing of the frame can be handled better.
[0013] Preferably, an assembly rod is rotatably connected through the surface of the processing frame, wherein an auxiliary plate is installed on the arc surface of the assembly rod, and torsion springs are respectively sleeved on the arc surfaces at both ends of the assembly rod, wherein the two ends of the torsion springs are respectively connected and fixed to the assembly rod and the surface of the processing frame, and a positioning plate is installed on the inner wall of the processing frame.
[0014] The effect achieved by the above components is as follows: after the plastic is crushed by the rotating blades, it can fall onto the surface of the auxiliary plate. When a certain amount of material accumulates on the surface of the auxiliary plate, it can be pressed down, causing the material to slide off the auxiliary plate. Afterwards, the auxiliary plate will rotate back to the position of abutting the inner wall of the processing frame under the torsional force of the torsion spring, so that the material is not easy to accumulate excessively in the incineration chamber, thus improving the efficiency of the device.
[0015] Preferably, an auxiliary component is provided on one side of the processing frame, wherein the auxiliary component includes a push plate, and an installation groove is provided through one side of the processing frame. The push plate is slidably disposed with the inner wall of the installation groove, and a connecting plate is installed on the surface of the processing frame, wherein the output end of an electric telescopic rod provided on the surface of the connecting plate is connected to the push plate.
[0016] The effect achieved by the above components is that the use of the pretreatment device can make the plastic more efficient and faster, thus making it easier to process the plastic and put it into the incinerator.
[0017] Preferably, sliders are fixedly connected to both sides of the surface of the push plate, wherein the sliders are slidably connected to the grooves in the inner wall of the processing frame.
[0018] The effect achieved by the above components is that the sliding setting of the slider and the groove allows the displacement of the push plate to be better stabilized, thereby improving the performance of the auxiliary components.
[0019] Preferably, the surface of the processing frame is fixedly connected to two sides of the mounting groove, wherein the blocks ensure the normal use of the push plate.
[0020] The effect achieved by the above components is that, by setting the stop, when the push plate slides under the drive of the electric telescopic rod, it is not easy to detach from the inner wall of the mounting groove, thereby ensuring that the push plate can normally push the plastic crushed material into the incineration chamber.
[0021] The beneficial effects of this utility model are: When plastic containing drug residues is treated in an incinerator, this invention can better ensure the dispersion and breakage of plastic products, making it less prone to clumping. This ensures that the plastic is heated evenly during incineration, guaranteeing the complete decomposition of drug residues and materials, and improving the treatment effect.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium.

[0027] Figure 1 and Figure 2 The device shown includes an incinerator 1, an incineration chamber 4 on the inner wall of the incinerator 1, a furnace door 2 on the surface of the incinerator 1, an exhaust pipe 3 on the top of the incinerator 1, and a pretreatment device 5 on the surface of the incinerator 1. The pretreatment device 5 crushes the plastic to be incinerated using a treatment frame 51 and a blade 53. An auxiliary component 6 is provided on one side of the treatment frame 51.
[0028] Figure 1 - Figure 6The pretreatment device 5 shown includes a treatment frame 51, which is connected to the combustion chamber 4 of the incinerator 1. Two mounting rods 52 are rotatably connected through the inner wall of the treatment frame 51. Several evenly distributed blades 53 are fixedly connected to the arc surface of the mounting rods 52. The incinerator 1 is rotatably connected to two connecting shafts 55, each with meshing gears 56 mounted on its arc surface. Sprockets 57 are fixedly connected to the arc surfaces of the two mounting rods 52 and the two connecting shafts 55. One mounting rod 52 and one of the sprockets 57 on the surface of one connecting shaft 55 are meshed together via a chain 58. When using the incinerator 1 to treat plastic products containing pesticide residues, the combustion chamber 4 is first activated to generate high temperatures within the chamber, while ensuring the furnace door 2 remains closed. The plastic is then added into the processing frame 51. At this time, the servo motor 54 on the surface of the processing frame 51 will start running. Because the two mounting rods 52 are engaged with the two connecting shafts 55 through sprockets 57 and chains 58, and the two connecting shafts 55 are engaged through gears 56, the two mounting rods 52 will rotate in opposite directions under the drive of the servo motor 54. At this time, the plastic product will be cut and broken when it comes into contact with the blade 53, and finally enter the incineration chamber 4 for incineration. When the plastic containing drug residues is treated harmlessly in the incinerator 1, it can better ensure the dispersion and breakage of the plastic products, and it is not easy for them to clump together. This ensures that the plastic is heated evenly when it is burned, ensuring the complete decomposition of drug residues and materials, and improving the treatment effect.
[0029] Figure 1 - Figure 6 A rotating shaft 59 is mounted on the surface of the processing frame 51 shown. A baffle 510 is rotatably connected to the arc surface of the rotating shaft 59. By setting the baffle 510, during the interval of crushing and incinerating the material, the baffle 510 can be rotated along the arc surface of the rotating shaft 59 to close the opening of the processing frame 51. At this time, the environment inside the incinerator 1 can be kept relatively closed, so that the temperature is not prone to abnormal fluctuations. An operating handle 511 is fixedly connected to one side surface of the baffle 510. The operating handle 511 improves the ease of use of the baffle 510. By setting the operating handle 511, the baffle 510 can be operated more conveniently when rotating, and the processing frame 51 can be opened and closed better.
[0030] Figure 1 - Figure 6An assembly rod 512 is rotatably connected through the surface of the processing frame 51 shown. An auxiliary plate 513 is installed on the arc surface of the assembly rod 512, and torsion springs 514 are respectively sleeved on the arc surfaces of both ends of the assembly rod 512. The two ends of the torsion springs 514 are respectively connected and fixed to the surface of the assembly rod 512 and the processing frame 51. A positioning plate 515 is installed on the inner wall of the processing frame 51. When the plastic is crushed by the rotation of the blade 53, it can fall onto the surface of the auxiliary plate 513. When a certain amount of material accumulates on the surface of the auxiliary plate 513, the auxiliary plate 513 can be pressed, so that the material slides off the auxiliary plate 513. Afterwards, the auxiliary plate 513 will rotate back to the position of abutting the inner wall of the processing frame 51 under the torsional force of the torsion spring 514, so that the material is not prone to excessive accumulation in the incineration chamber 4, thus improving the efficiency of the device.
[0031] Figure 2 and, Figure 4 Figure 5 The auxiliary component 6 shown includes a pusher plate 61. A mounting groove 62 is provided through one side of the processing frame 51. The pusher plate 61 is slidably disposed with the inner wall of the mounting groove 62. A connecting plate 63 is installed on the surface of the processing frame 51. The output end of the electric telescopic rod 64 provided on the surface of the connecting plate 63 is connected to the pusher plate 61. When the plastic containing drug residue is crushed by the pretreatment device 5, the material will fall to the bottom of the inner wall of the processing frame 51. At this time, the electric telescopic rod 64 fixedly connected to the surface of the connecting plate 63 is activated, thereby driving the pusher plate 61 on its output end to slide, so that the pusher plate 61 is displaced in the inner wall of the processing frame 51. At this time, the material inside the processing frame 51 can be pushed and pushed into the incineration chamber 4. At this time, the use of the pretreatment device 5 can be more efficient and faster, thus making it easier to process the plastic and fill it into the incinerator 1.
[0032] Figure 2 and, Figure 4 Figure 5 The push plate 61 shown has sliders 66 fixedly connected to both sides of its surface. The sliders 66 are slidably connected to the grooves 65 on the inner wall of the processing frame 51. The sliding arrangement of the sliders 66 and the grooves 65 makes the displacement of the push plate 61 more stable, thereby improving the performance of the auxiliary component 6. The surface of the processing frame 51 is fixedly connected to both sides of the mounting groove 62. The stops 67 ensure the normal use of the push plate 61. The stops 67 prevent the push plate 61 from sliding out of the inner wall of the mounting groove 62 when it is driven by the electric telescopic rod 64, thus ensuring that the push plate 61 can push the plastic crushed material into the incineration chamber 4 normally.
[0033] Working Principle: When using incinerator 1 to process plastic products containing drug residues, the incineration chamber 4 is first activated to generate high temperatures, while ensuring the furnace door 2 remains closed. The plastic is then added to the processing frame 51. At this time, the servo motor 54 (Siemens SINAMICS S210) on the surface of the processing frame 51 starts operating. Because the two mounting rods 52 are engaged with the two connecting shafts 55 via sprockets 57 and chains 58, and the two connecting shafts 55 are engaged via gears 56, the two mounting rods 52 rotate in opposite directions under the drive of the servo motor 54. The plastic products are then cut and broken upon contact with the blades 53 before entering the incineration chamber 4 for incineration. This process, when using incinerator 1 for harmless treatment of plastic products containing drug residues, ensures better dispersion and breakage of the plastic products, preventing clumping and ensuring uniform heating during incineration. This guarantees complete decomposition of drug residues and materials, improving the processing efficiency.
[0034] After the plastic containing drug residues is crushed by the pretreatment device 5, the material will fall to the bottom of the inner wall of the processing frame 51. At this time, the electric telescopic rod 64 fixedly connected to the surface of the connecting plate 63 is activated, which drives the sliding of the push plate 61 at its output end, causing the push plate 61 to move in the inner wall of the processing frame 51. At this time, the material inside the processing frame 51 can be pushed and pushed into the incineration chamber 4. The use of the pretreatment device 5 can be more efficient and faster, thus making it easier to process the plastic and fill it into the incinerator 1.
