Description

Technical Field

[0001] This utility model relates to the field of extruded polystyrene board recycling technology, specifically to a waste recycling device for thermal insulation extruded polystyrene boards. Background Technology

[0002] Extruded polystyrene (XPS) board is a rigid foam plastic board made by extruding polystyrene resin and polymers while heating and mixing them with a catalyst. It has an independent, closed-cell bubble structure inside and is an environmentally friendly insulation material with excellent properties such as high compressive strength, low water absorption, moisture resistance, air tightness, light weight, corrosion resistance, super anti-aging (almost no aging after long-term use), and low thermal conductivity.

[0003] For the recycling of XPS extruded polystyrene (XPS) board waste, a crushing device is usually used to crush the XPS board. The crushed XPS board is then added to a melting mechanism to change its shape for reuse. For example, Chinese utility model patent CN217916278U discloses a crushing device for recycling XPS XPS board waste.

[0004] However, in actual use, it has been found that the aforementioned fertilizer recycling devices for extruded polystyrene (XPS) boards generate a large amount of fine plastic dust during the crushing and grinding process. Long-term inhalation of this dust by operators can cause serious damage to the respiratory system, potentially leading to pneumoconiosis, chronic bronchitis, and other conditions. Furthermore, when plastic dust reaches a certain concentration in the air, it is highly susceptible to explosion upon contact with sparks (such as from equipment friction, static electricity, or electrical switches), resulting in a powerful and potentially serious safety hazard in industrial production. Utility Model Content

[0005] The purpose of this utility model is to provide a waste recycling device for thermal insulation extruded polystyrene boards, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste recycling device for thermal insulation extruded polystyrene board, comprising a box, a crushing component, a driving component, a transmission component, a suction pipe component, and a dust collection component.

[0007] The box has a feed inlet at the top and a discharge outlet at the bottom. A crushing component is installed inside the box. A drive component for driving the crushing component is installed on one side of the box, and a transmission component for driving the crushing component is installed on the other side of the box. A suction pipe assembly is installed inside the feed inlet. The suction pipe assembly is connected to a dust collection assembly, which is located on one side of the box.

[0008] In a preferred embodiment of this invention, the crushing assembly includes a first crushing roller and a second crushing roller, which are parallel to each other and symmetrically rotatably connected to the inner wall of the housing. The extruded polystyrene board is crushed by the relative rotation of the first and second crushing rollers, which employ a blade-type crushing method.

[0009] In a preferred embodiment of this invention, the drive assembly includes a drive motor, a first drive wheel, a second drive wheel, and a belt. The drive motor is located on the side of the housing. The first drive wheel is connected to the drive shaft of the drive motor, and the second drive wheel is connected to one end of the first crushing roller. The belt is fitted onto the first and second drive wheels. By driving the first drive wheel to rotate via the drive motor, the first drive wheel drives the second drive wheel to rotate via the belt. This, in turn, causes the second drive wheel to drive the first crushing roller to rotate. The first crushing roller, through a transmission assembly, drives the second crushing roller to rotate relative to it.

[0010] In a preferred embodiment of this invention, the transmission assembly includes a driving gear and a driven gear. The driving gear is connected to the first crushing roller, and the driven gear is connected to the second crushing roller. The driving gear and the driven gear mesh with each other. Rotation of the first crushing roller causes the driving gear to rotate, which in turn drives the driven gear to rotate, and the driven gear, in turn, drives the second crushing roller to rotate.

[0011] In a preferred embodiment of this invention, the suction tube assembly includes a dust collection tube and a suction tube. The dust collection tube is fixed to the outside of the feed inlet, and both ends of the dust collection tube are connected to the suction tube. Several suction ports are evenly distributed below the suction tube, and the suction tube is inserted inside the feed inlet. By connecting the dust collection tube to the suction assembly, the suction assembly draws plastic dust into the dust collection tube through the suction ports of the suction tube, and then the dust enters the suction assembly through the dust collection tube.

[0012] In a preferred embodiment of this invention, the dust collection assembly includes a storage box, a connecting pipe, and a dust collection fan. The storage box is fixed to one side of the housing and is connected to a dust collection pipe via the connecting pipe. The dust collection fan is connected to the outside of the storage box, and a filter screen is installed between the dust collection fan and the storage box. By drawing air from the storage box using the dust collection fan, a negative pressure is created inside the storage box, allowing the storage box to draw plastic dust from the dust collection pipe and the dust collection pipe through the connecting pipe.

[0013] In a preferred embodiment of this invention, a baffle plate is fixed inside the feed inlet. The baffle plate is inclined and positioned above the suction pipe. The baffle plate serves to prevent the extruded polystyrene fertilizer from falling between the first and second crushing rollers, while also protecting the suction pipe.

[0014] In a preferred embodiment of this invention, both the housing and the drive motor are fixed with a base plate. The base plate serves to provide support and fixation.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention features high crushing efficiency and good recycling effect. The relative rotation of the two crushing rollers can fully shear and crush the waste material, quickly crushing it into uniform fine particles, meeting the requirements for recycling and reuse, and greatly improving the utilization rate of waste materials.

[0016] It is highly environmentally friendly. The dust collection component works simultaneously during crushing, adsorbing and filtering dust through negative pressure to prevent dust from spreading and polluting the air, protecting the health of operators and reducing environmental cleaning costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a waste recycling device for thermal insulation extruded polystyrene board, including a box 1, a crushing component 2, a driving component 3, a transmission component 4, a suction pipe component 5, and a dust collection component 6.

[0023] The box 1 has a feed inlet 101 at the top and a discharge outlet 102 at the bottom. The box 1 is equipped with a crushing component 2. A drive component 3 for driving the crushing component 2 is provided on one side of the box 1, and a transmission component 4 for driving the crushing component 2 is provided on the other side of the box 1. A suction pipe assembly 5 is provided inside the feed inlet 101. The suction pipe assembly 5 is connected to a dust collection component 6, which is located on one side of the box 1.

[0024] The drive assembly 3 is used to drive the crushing assembly 2 to crush the extruded board waste, the transmission assembly 4 realizes the transmission of the crushing assembly 2, and the dust collection assembly 5 works with the suction tube assembly 6 to achieve the dust collection function.

[0025] Furthermore, the crushing assembly 2 includes a first crushing roller 201 and a second crushing roller 202, which are parallel to each other and symmetrically rotatably connected to the inner wall of the housing 1. The extruded board is crushed by the relative rotation of the first crushing roller 201 and the second crushing roller 202, which employ a blade-type crushing method.

[0026] Furthermore, the drive assembly 3 includes a drive motor 301, a first drive wheel 302, a second drive wheel 303, and a belt 304. The drive motor 301 is located on the side of the housing 1. The first drive wheel 302 is connected to the drive shaft of the drive motor 301. The second drive wheel 303 is connected to one end of the first crushing roller 201. The belt 304 is sleeved on the first drive wheel 302 and the second drive wheel 303. By driving the first drive wheel 302 to rotate through the drive motor 301, the first drive wheel 302 drives the second drive wheel 303 to rotate through the belt 304. Then, the second drive wheel 303 drives the first crushing roller 201 to rotate. The first crushing roller 201 drives the second crushing roller 202 to rotate relative to each other through the transmission assembly 4.

[0027] Furthermore, the transmission assembly 4 includes a driving gear 401 and a driven gear 402. The driving gear 401 is connected to the first crushing roller 201, and the driven gear 402 is connected to the second crushing roller 202. The driving gear 401 and the driven gear 402 mesh with each other. Rotation of the first crushing roller 201 causes the driving gear 401 to rotate, which in turn drives the driven gear 402 to rotate, and the driven gear 402 in turn drives the second crushing roller 202 to rotate.

[0028] Furthermore, the suction tube assembly 5 includes a dust collection tube 501 and a suction tube 502. The dust collection tube 501 is fixed to the outside of the feed inlet 101, and both ends of the dust collection tube 501 are connected to the suction tube 502. A plurality of suction ports 5021 are evenly distributed below the suction tube 502, and the suction tube 502 is inserted inside the feed inlet 101. By connecting the dust collection tube 501 to the suction assembly 6, the suction assembly 6 draws plastic dust into the dust collection tube 501 through the suction ports 5021 of the suction tube 502, and then the dust enters the suction assembly 6 through the dust collection tube 501.

[0029] Furthermore, the dust collection assembly 6 includes a storage box 601, a connecting pipe 602, and a dust collection fan 603. The storage box 601 is fixed to one side of the housing 1 and is connected to the dust collection pipe 501 via the connecting pipe 602. The dust collection fan 603 is connected to the outside of the storage box 601, and a filter screen is provided between the dust collection fan 603 and the storage box 601. The dust collection fan 603 draws air from the storage box 601, creating a negative pressure inside the storage box 601, which then draws in plastic dust from the dust collection pipe 501 and the dust collection pipe 502 through the connecting pipe 602.

[0030] Furthermore, a baffle plate 1011 is fixed inside the feed inlet 101. The baffle plate 1011 is inclined and located above the suction pipe 502. By setting the baffle plate 1011, the material is blocked, ensuring that the extruded board fertilizer falls between the first crushing roller 201 and the second crushing roller 202, while also protecting the suction pipe 502.

[0031] Furthermore, a base plate 7 is fixed below both the housing 1 and the drive motor 301. The base plate 7 serves to provide support and fixation.

[0032] In summary, when using this device, the operator puts the waste material of the thermal insulation extruded board into the feed port 101 above the box 1. The baffle plate 1011 installed at an inclination inside the feed port 101 will guide the waste material to ensure that the waste material falls accurately between the first crushing roller 201 and the second crushing roller 202 inside the box 1, while avoiding the waste material from directly hitting the suction pipe assembly 5, thus protecting the suction pipe 502.

[0033] Start the drive motor 301 in the drive assembly 3. The drive shaft of the drive motor 301 drives the first drive wheel 302 to rotate. The first drive wheel 302 transmits power to the second drive wheel 303 through the belt 304. The second drive wheel 303 then drives the first crushing roller 201 connected to it to rotate.

[0034] When the first crushing roller 201 rotates, the drive gear 401 connected to one end of it rotates synchronously. Since the drive gear 401 meshes with the passive gear 402 at one end of the second crushing roller 202, the drive gear 401 will drive the passive gear 402 to rotate in the opposite direction, thereby making the second crushing roller 202 and the first crushing roller 201 form a "relatively parallel rotation" motion state.

[0035] The first and second crushing rollers 202, which adopt a blade-type structure, shear and crush the extruded board waste falling between them during relative rotation, processing large pieces of waste into small particles that meet recycling requirements. The crushed particles are finally discharged from the discharge port 102 at the bottom of the box 1, completing the core step of waste crushing and recycling.

[0036] During the crushing process, the dust collection component 6 is activated simultaneously. When the dust collection fan 603 is running, it draws air from the storage box 601, creating a negative pressure environment inside the storage box 601. The storage box 601 transmits the negative pressure to the dust collection pipe 501 of the suction pipe component 5 through the connecting pipe 602. The dust collection pipe 501 then transmits the negative pressure to the suction pipe 502 inserted in the feed inlet 101. Several suction ports 5021 below the suction pipe 502 actively adsorb the plastic dust generated during the crushing process. The dust enters the suction pipe 502 through the suction ports 5021, and then finally enters the storage box 601 through the dust collection pipe 501 and the connecting pipe 602. At the same time, the filter screen between the storage box 601 and the dust collection fan 603 can prevent dust from entering the dust collection fan 603, ensuring the normal operation of the fan and achieving efficient dust collection.

[0037] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
