Description

Technical Field

[0001] This utility model relates to the technical field of industrial hazardous waste treatment, and in particular to a hazardous waste crushing and explosion-proof treatment device. Background Technology

[0002] Hazardous waste refers to solid waste that is listed in the National Hazardous Waste List or identified as having hazardous characteristics according to the national hazardous waste identification standards and methods. If such waste is discharged or stored at will without proper treatment, it will seriously pollute water bodies and soil, weaken regional environmental functions, disrupt ecological balance, endanger human health, and hinder the process of sustainable development under the long-term effects of rainwater and groundwater infiltration and diffusion. Therefore, the harm caused by the failure to treat or the improper treatment and disposal of hazardous waste is extremely serious.

[0003] Currently, the most common pretreatment process used in the hazardous waste industry is the crushing system. After crushing and pretreatment, most of the waste is sent into the feed pit and then into the rotary kiln for incineration. In the feeding stage before hazardous waste crushing, inert gases such as nitrogen are introduced to replace the air in the sealed chamber, thereby reducing the oxygen concentration inside the chamber and effectively preventing safety accidents such as combustion and explosion of hazardous waste in the sealed chamber.

[0004] However, existing replacement operations generally employ a double-sealed door design, placing hazardous waste within a closed space between the two doors before nitrogen is introduced to replace the air. This batch-intermittent feeding method has several drawbacks, particularly when processing batches of impermeable and soft waste. Because the waste is stationary, sealed cavities may exist inside that are difficult to replace, leading to poor replacement efficiency. Furthermore, this method cannot achieve continuous feeding, thus affecting replacement efficiency and the efficiency of subsequent crushing operations. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a hazardous waste crushing and explosion-proof treatment device that can continuously realize the feeding operation of waste materials, and the waste materials can undergo multiple efficient replacements in a moving state, thereby significantly improving the replacement effect.

[0007] To achieve the above objectives, this utility model proposes a hazardous waste crushing and explosion-proof treatment device, comprising a sealed chamber, a multi-stage replacement mechanism, crushed components, and a dust absorption mechanism. The sealed chamber has a conveying channel at its inlet, and the outlet of the conveying channel is connected to the sealed chamber. Multiple replacement modules are provided on the conveying channel, each including an air inlet pipe and an air outlet pipe. The multi-stage replacement mechanism includes a rotating shaft and multiple sealing plates circumferentially distributed outside the rotating shaft. The rotating shaft is movably disposed within the conveying channel, with one end penetrating the sealed chamber and equipped with a motor. The outer edges of the sealing plates slide in contact with the inner wall of the channel, and a conveying cavity is formed between adjacent sealing plates and the rotating shaft. The crushed components are disposed inside the sealed chamber. The dust absorption mechanism includes a suction strip and a driving component. The suction strip is disposed on the inner wall of the sealed chamber, and the driving component is connected to the suction strip.

[0008] In addition, the hazardous waste crushing and explosion-proof treatment device proposed in the application may also have the following additional technical features:

[0009] Specifically, a sealing strip is provided at the entrance edge of the conveying channel.

[0010] Specifically, there are two suction strips, which are respectively located on the symmetrical sides of the sealed chamber. The driving component includes an exhaust pipe, the input end of which is connected to the two suction strips. The output end of the exhaust pipe is provided with a suction fan, and the rotating shaft of the suction fan passes through the exhaust pipe and is connected to the linkage component.

[0011] Specifically, the linkage is located on the outside of the sealed chamber. The linkage includes two shafts and two meshing gears. The two shafts are movably mounted on the sealed chamber and connected to each other by a synchronous belt. One of the shafts is connected to the rotating shaft of the suction fan. The two gears are respectively mounted on the rotating shaft and the other shaft.

[0012] Specifically, the conveying channel is equipped with an oxygen concentration monitor.

[0013] Specifically, a mounting base is provided on the outside of the sealed chamber, and the motor is mounted on the mounting base.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] 1. During the continuous conveying of waste materials through a multi-stage replacement mechanism, the waste materials dynamically rotate around the outer circumference of the rotating shaft within the conveying chamber and undergo multiple efficient replacements. This allows the waste materials to complete the replacement process while in continuous motion, thus significantly improving the replacement effect.

[0016] 2. The design of the multi-stage replacement mechanism enables continuous supply of waste materials, which not only ensures the efficient operation of the replacement process, but also lays a solid foundation for subsequent crushing operations, effectively improving the overall operating efficiency.

[0017] 3. The linkage can effectively transfer the energy generated by the rotation of the rotating shaft to the suction fan, realizing the rational use of motor power, which is environmentally friendly and energy-saving.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] The hazardous waste crushing and explosion-proof treatment device of this utility model is described below with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, the hazardous waste crushing and explosion-proof treatment device of this utility model embodiment may include a sealed chamber 10, a multi-stage replacement mechanism 30, crushed parts 60, and a dust absorption mechanism (not shown in the figure).

[0028] The sealed chamber 10 has a conveying channel 20 at its feed inlet, and the outlet of the conveying channel 20 is connected to the sealed chamber 10. The conveying channel 20 is equipped with multiple replacement modules, each of which may include an air inlet pipe 21 and an air outlet pipe 22. The air inlet pipe 21 and the air outlet pipe 22 are respectively located on symmetrical sides of the conveying channel 20. An oxygen concentration monitor 24 is installed inside the conveying channel 20.

[0029] The multi-stage replacement mechanism 30 may include a rotating shaft 31 and a plurality of sealing plates 32 circumferentially distributed outside the rotating shaft 31. The rotating shaft 31 is movably disposed within the conveying channel 20, and one end of the shaft passes through the sealed chamber 10 and is equipped with a motor 50. A mounting base 11 is provided on the outside of the sealed chamber 10, and the motor 50 is mounted on the mounting base 11.

[0030] The outer edge of the sealing plate 32 slides in contact with the inner wall of the channel, and a conveying cavity 40 is formed between two adjacent sealing plates 32 and the rotating shaft 31. A sealing strip 23 is provided at the entrance edge of the conveying channel 20, and the sealing strip 23 further enhances the sealing performance of the inner wall of the conveying channel 20 to the conveying cavity 40.

[0031] It should be noted that the conveying cavity 40 described in this embodiment can rotate with the rotating shaft 31. When the conveying cavity 40 is located at the inlet and outlet of the conveying channel 20, it is in an open state, which facilitates the smooth entry and exit of waste materials. Conversely, when the conveying cavity 40 is blocked by the inner wall of the conveying channel 20, it automatically switches to a closed state. The conveying cavity 40 in the closed state can perform replacement operations.

[0032] It should be noted that, in this embodiment, the waste-carrying conveying chamber 40, during the transfer process from the inlet to the outlet of the conveying channel 20, can be sequentially connected to multiple replacement modules to achieve efficient multi-stage replacement. During the replacement process, inert gases such as nitrogen are injected into the sealed conveying chamber 40 through the inlet pipe 21, while air is discharged through the outlet pipe 22, effectively reducing the oxygen concentration within the chamber. Crucially, this replacement process is completed during the continuous movement of the waste, significantly optimizing replacement efficiency. Furthermore, the real-time intervention of the oxygen concentration monitor 24 ensures accurate monitoring of the oxygen concentration within the conveying chamber 40.

[0033] The crushing component 60 is located inside the sealed chamber 10 and below the outlet of the conveying channel 20. Waste material can enter the crushing component 60 through the outlet of the conveying channel 20 and be crushed by the crushing component 60. The crushed waste material can be discharged to the external material pit.

[0034] As a possible alternative, a multi-stage replacement mechanism 30 can also be installed at the discharge chute of the sealed chamber 10 to prevent the waste from leaving the nitrogen-filled area and coming into contact with air, thereby igniting the fuel pit.

[0035] As a possible alternative, a displacement module can also be installed inside the sealed chamber 10. During the waste crushing process, nitrogen can be introduced into the sealed chamber 10 to reduce the oxygen concentration inside, thereby creating a low-oxygen or oxygen-free environment. This environment helps prevent sparks generated by friction, impact, or other factors during the crushing process from causing combustion or explosion.

[0036] The dust absorption mechanism may include suction strips 70 and a driving component. The suction strips 70 are disposed on the inner wall of the sealed chamber 10, and the driving component is connected to the suction strips 70. Two suction strips 70 are provided, respectively located on symmetrical sides of the sealed chamber 10. The driving component may include an exhaust pipe 72, the input end of which is connected to both suction strips 70. A suction fan 721 is disposed inside the output end of the exhaust pipe 72, and the rotating shaft 722 of the suction fan 721 passes through the exhaust pipe 72 and is connected to a linkage 80. The linkage 80 is located on the outer side of the sealed chamber 10 and may include two shafts 81 and two meshing gears 82. The two shafts 81 are movably disposed on the sealed chamber 10 and are connected to each other by a synchronous belt 83. One shaft 81 is connected to the rotating shaft 722 of the suction fan 721, and the two gears 82 are respectively disposed on a rotating shaft 31 and the other shaft 81.

[0037] It should be noted that when the motor 50 drives the rotating shaft 31 to rotate, the rotating shaft 31 drives another gear 82 to rotate synchronously through the gear 82 on it. In conjunction with the timing belt 83, the two shafts 81 rotate synchronously. The rotation of the shafts 81 drives the rotating shaft 722 of the suction fan 721 in this embodiment to rotate, thereby activating the suction fan 721 and causing the exhaust pipe 72 to generate a strong suction force on the suction strip 70, effectively removing the dust generated in the crushing operation inside the sealed chamber 10.

[0038] Specifically, during the actual explosion-proof crushing operation of waste materials, the operator first starts the motor 50, which synchronously drives the rotating shaft 31 and the suction fan 721 to start working. Subsequently, a large amount of waste material can be fed into the inlet of the conveying channel 20 one by one, and enter each conveying chamber 40 in a continuous batch manner, realizing continuous feeding in the sealed chamber 10.

[0039] As the conveying chamber 40 carrying the waste rotates within the conveying channel 20, it can sequentially connect with multiple replacement modules for step-by-step replacement. Simultaneously, the waste dynamically rotates around the outer circumference of the rotating shaft 31; this continuous motion greatly enhances the replacement effect. When the conveying chamber 40 rotates to the outlet position, the waste falls into the sealed chamber 10 under gravity and is processed by the crushing component 60. During this process, the suction strip 70 actively absorbs and discharges dust and impurities generated during crushing, effectively preventing the risk of dust explosion. Finally, the crushed waste is smoothly discharged into the external material pit.

[0040] In summary, the hazardous waste crushing and explosion-proof treatment device of this utility model embodiment can continuously realize the feeding operation of waste materials, and the waste materials can undergo multiple efficient replacements in a moving state, thereby significantly improving the replacement effect.
