Description

Technical Field

[0001] This utility model specifically relates to the technical field of foam recycling devices, and more specifically to a device for recycling waste materials after EPS foam board cutting. Background Technology

[0002] EPS foam board, also known as polystyrene foam board, is a white material made of expandable polystyrene beads containing volatile liquid foaming agents. After pre-expansion by heating, the beads are molded in a mold and have a micro-closed-cell structure. EPS foam board consists of approximately 98% air and 2% polystyrene. The air trapped within the honeycomb structure is a poor conductor of heat and plays a decisive role in its thermal insulation performance.

[0003] Foam board processing requires shaping and cutting to create a specific shape. This process generates a large amount of debris and scrap pieces.

[0004] Traditionally, waste EPS foam board scrap is recycled by directly feeding it into a granulator for melting and then extruding it into granules for reuse. However, some scrap is in large pieces, which makes it difficult for the scrap to fall, causing blockages at the granulator's feed inlet.

[0005] Some companies also use crushers to pulverize large pieces of waste material, but because the pulverized foam board particles are relatively light, they may scatter, which is not conducive to safe production in the workshop. Utility Model Content

[0006] The purpose of this utility model is to provide a device for recycling waste material after EPS foam board cutting. After the foam board is crushed, the crushed material is conveyed by wind power, which can prevent the crushed material from scattering. First, it can ensure the cleanliness of the workshop production environment; second, it can greatly avoid the occurrence of fire. This solves the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An EPS foam board cutting waste recycling device includes a crusher for crushing EPS foam, and a screw conveyor is installed at the bottom of the crusher.

[0009] The screw conveyor is connected to the centrifugal fan via a connecting elbow, and the centrifugal fan is connected to the storage tank via a conveying pipe; a granulation extruder is connected to the bottom of the storage tank.

[0010] As a further technical solution of this utility model, the crusher is fixed to the frame body, and a hopper is installed on the top of the crusher.

[0011] As a further technical solution of this utility model, the crusher includes a machine shell, and two sets of crushing components are installed inside the machine shell. The crushing components include crushing rollers and extrusion rollers.

[0012] The crushing roller and the extrusion roller are mounted inside the machine housing at both ends by bearings, and one end is connected to the other by gears; either end of the crushing roller or the extrusion roller extends to the outside of the machine housing and is connected to the speed reducer unit for transmission.

[0013] As a further technical solution of this utility model, the screw conveyor includes a tube shell fixed to the bottom of the machine housing, and a feeding screw is installed inside the tube shell, with a motor assembly connected to one end of the feeding screw.

[0014] As a further technical solution of this utility model, the top of the storage box is provided with a circular hole, and a filter element is embedded in the circular hole; an exhaust fan is provided above the filter element, and the exhaust fan is fixed to the top of the storage box.

[0015] As a further technical solution of this utility model, the storage box is fixed on the bracket.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the speed reducer unit drives the crushing roller and the extrusion roller to rotate under the cooperation of gears, so as to crush the blocky residue. First, the crushing roller is used to crush the material, and then the extrusion roller is used to granulate the foam as much as possible.

[0018] 2. In this utility model, the crushed foam particles fall into the pipe shell, and the motor assembly drives the feeding screw to rotate and convey the foam particles. This can prevent excessive material accumulation and ensure the normal transmission of wind power.

[0019] 3. In this utility model, after the centrifugal fan transports the crushed foam particles to the storage bin, the exhaust fan extracts the gas from the storage bin and filters the gas through a filter element to prevent the foam particles from flying out; this ensures that the crushed foam can be directly used for melting and granulation, and also avoids the occurrence of particle scattering.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 In this embodiment of the utility model, an EPS foam board cutting waste recycling device includes a crusher 2 for EPS foam crushing, and a screw conveyor 4 is installed at the bottom of the crusher 2.

[0030] The screw conveyor 4 is connected to the centrifugal fan 6 via the connecting elbow 5, and the centrifugal fan 6 is connected to the storage tank 8 via the conveying pipe 7; the bottom of the storage tank 8 is connected to the granulation extruder 9.

[0031] More specifically, the crusher 2 is fixed to the frame body 1, and a hopper 3 is installed on the top of the crusher 2.

[0032] By adopting the above technical solution, when using it, the surplus material is first put into the hopper 3, crushed by the crusher 2, and then the crushed foam is conveyed out by the screw conveyor 4. Under the action of the centrifugal fan 6, the crushed foam particles are conveyed through the conveying pipe 7 to the storage box 8 for storage. The foam particles in the storage box 8 enter the granulation extruder 9, and are then melted at high temperature and extruded into strips. After being cooled by cold water and cut, they are granulated and formed.

[0033] In this embodiment, the crusher 2 includes a machine housing 21, and two sets of crushing components are installed inside the machine housing 21. The crushing components include a crushing roller 23 and a squeezing roller 24.

[0034] The crushing roller 23 and the extrusion roller 24 are mounted inside the machine housing 21 at both ends by bearings, and one end is connected to the other by gear meshing; either end of the crushing roller 23 or the extrusion roller 24 extends to the outside of the machine housing 21 and is connected to the reducer unit 22 for transmission.

[0035] By adopting the above technical solution, the reducer 22 drives the crushing roller 23 and the extrusion roller 24 to rotate under the cooperation of gears, so as to crush the blocky residue. First, the crushing roller 23 is used for crushing, and then the extrusion roller 24 is used to achieve the granulation of foam as much as possible.

[0036] In this embodiment, the screw conveyor 4 includes a tube shell 41 fixed to the bottom of the outer casing 21. A feeding screw 42 is installed inside the tube shell 41, and one end of the feeding screw 42 is connected to a motor assembly 43.

[0037] The crushed foam particles fall into the tube shell 41. The motor assembly 43 drives the feeding screw 42 to rotate and convey the foam particles. This can prevent excessive material accumulation and ensure normal transmission of air power.

[0038] In this embodiment, the top of the storage box 8 is provided with a circular hole, and a filter element 12 is embedded in the circular hole; an exhaust fan 11 is provided above the filter element 12, and the exhaust fan 11 is fixed to the top of the storage box 8.

[0039] After the centrifugal fan 6 conveys the crushed foam particles to the storage bin 8, the exhaust fan 11 extracts the gas from the storage bin 8 and filters the gas through the filter element 12 to prevent the foam particles from flying out. This ensures that the crushed foam can be directly used for melting and granulation, while also preventing the particles from scattering.

[0040] In this embodiment, the storage box 8 is fixed on the bracket 10.

[0041] The working principle of this utility model is as follows: First, the surplus material is placed into the hopper 3. The reducer unit 22, driven by gears, rotates the crushing roller 23 and the extrusion roller 24 to crush the lumpy surplus material. The crushing roller 23 first performs the crushing process, and then the extrusion roller 24 is used to granulate the foam as much as possible. The crushed foam particles fall into the tube shell 41. The motor assembly 43 drives the feeding screw 42 to rotate and convey the foam particles. Under the action of the centrifugal fan 6, the powder... The crushed foam particles are transported to the storage bin 8 through the conveying pipe 7. After the centrifugal fan 6 transports the crushed foam particles to the storage bin 8, the exhaust fan 11 extracts the gas from the storage bin 8 and filters the gas through the filter element 12 to prevent the foam particles from flying out. This ensures that the crushed foam can be directly used for melting and granulation, and also avoids the occurrence of particle scattering. The foam particles in the storage bin 8 enter the granulation extruder 9, and are then melted at high temperature and extruded into strips. After being cooled by cold water and cut, they are granulated and formed.
