Description

Technical Field

[0001] This utility model relates to the field of polyethylene foam material processing technology, and in particular to a pretreatment device for fully recyclable polyethylene foam material raw materials. Background Technology

[0002] In the production process of fully recycled polyethylene foam, raw material pretreatment is a crucial step, with raw material drying being an important one. Existing raw material drying equipment typically involves simply placing the raw materials in a drying chamber for static drying. This relatively static state results in uneven heating, low drying efficiency, and the possibility of incomplete drying in some areas, negatively impacting the quality of subsequent polyethylene foam production. Utility Model Content

[0003] The main objective of this invention is to provide a pretreatment device for fully recyclable polyethylene foam material raw materials, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pretreatment device for fully recyclable polyethylene foam material raw materials, comprising an insulation shell, an exhaust pipe provided at the upper part of the insulation shell, columns provided at the four corners of the lower part of the insulation shell, a discharge port provided on the left side of the insulation shell, a support frame provided in the middle of the discharge port, a central tube rotatably connected to the middle of the support frame, a perforated sleeve provided in the middle of the insulation shell, a feeding box provided on the right side of the insulation shell, and the right end of the central tube penetrating and rotatably connected to the middle of the right side of the feeding box. A pulley is fixedly connected to the outer periphery of the right end. The feeding box is connected to the insulation shell. An auger blade is fixedly connected to the outer periphery of the left side of the central tube. Several holes are provided on the left side of the central tube. The right end of the central tube is rotatably connected to the outer periphery of one end of the heating tube. The other end of the heating tube is fixedly connected to the output end of the air pump. The air pump is installed on the rear side of the feeding box. An electric heating wire is provided inside the heating tube. A geared motor is installed at the front of the feeding box. A pulley is provided at the output end of the right side of the geared motor. The outer periphery of the pulley is meshed with both ends of the belt.

[0005] Preferably, multiple material-turning plates are fixedly connected to the outer periphery of the auger blade.

[0006] Preferably, the other end of the exhaust pipe is connected to a waste heat recovery device.

[0007] Preferably, a slag discharge port is provided in the middle of the lower side of the insulation shell.

[0008] Preferably, the heating tube is wrapped with heat-insulating cotton.

[0009] Preferably, the air pump input end is provided with an air filter.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] A drive air pump heats the gas through a heating tube and then delivers it into the central tube, allowing hot air to escape from the holes in the central tube. This dries the raw material inside the porous sleeve. A drive geared motor, via pulleys and belts, rotates the central tube, which in turn rotates the auger blades. As the auger blades rotate, they also rotate the tipping plate, causing the raw material to move to the left while being flipped by the tipping plate. This ensures that the hot air exiting from the holes in the central tube can better dry the raw material, guaranteeing the production quality of the subsequent polyethylene foam material.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-4As shown, a pretreatment device for fully recyclable polyethylene foam material includes an insulation shell 1, an exhaust pipe 2 at the top of the insulation shell 1, columns 4 at the four corners of the bottom of the insulation shell 1, a discharge port 5 on the left side of the insulation shell 1, a support frame 6 in the middle of the discharge port 5, a central tube 17 rotatably connected to the middle of the support frame 6, a perforated sleeve 16 in the middle of the insulation shell 1, a feeding box 7 on the right side of the insulation shell 1, the right end of the central tube 17 passing through and rotatably connected to the middle of the right side of the feeding box 7, a pulley 9 fixedly connected to the outer periphery of the right end of the central tube 17, the feeding box 7 and the insulation shell 1 being interconnected, an auger blade 12 fixedly connected to the outer periphery of the left side of the central tube 17, several holes on the left side of the central tube 17, a heating tube 11 rotatably connected to the outer periphery of one end of the right end of the central tube 17, the other end of the heating tube 11 fixedly connected to the output end of an air pump 15, and the air pump 15 being installed in the feeding box. 7. At the rear, the heating tube 11 is equipped with an electric heating wire. A geared motor 8 is installed at the front of the feeding box 7. A pulley 9 is installed at the output end on the right side of the geared motor 8. The outer circumference of the pulley 9 is meshed with both ends of the belt 10. The raw material is fed into the feeding box 7, driving the geared motor 8. Through the pulley 9 and the belt 10, the transmission causes the central tube 17 to rotate, which in turn drives the auger blades 12 to rotate, thereby moving the raw material inside the porous sleeve 16. The air pump 15 drives the gas to be heated through the heating tube 11 and then sent into the central tube 17, so that the hot air is discharged from the holes of the central tube 17, thereby drying the raw material inside the porous sleeve 16. The hot air removes the moisture, thus ensuring the dryness of the raw material. Through the rotation of the auger blades 12, the raw material can be continuously conveyed, thereby continuously drying the raw material.

[0019] Multiple tilting plates 14 are fixedly connected to the outer periphery of the auger blades 12, driving the reduction motor 8. Through pulleys 9 and belts 10, the central tube 17 rotates, causing the auger blades 12 to rotate. As the auger blades 12 rotate, they also rotate the tilting plates 14, causing the raw material to move to the left while being tilted by the tilting plates 14. This allows the hot air exhausted from the holes in the central tube 17 to better dry the raw material. The other end of the exhaust pipe 2 is connected to a waste heat recovery device. The system recovers waste heat from the dried hot air to save energy. A slag discharge port 3 is provided in the middle of the lower side of the insulation shell 1. During the process of conveying and turning the raw materials by the auger blades 12 and the tipping plate 14, some powder slag will be generated. The powder slag can be discharged and collected through the slag discharge port 3. The heating tube 11 is wrapped with heat insulation cotton to prevent heat loss and prevent the heating tube 11 from burning the staff. An air filter 13 is provided at the input end of the air pump 15 to prevent impurities in the air from contaminating the raw materials and to ensure the purity of the raw materials.

[0020] Working principle:

[0021] The raw materials are fed into the feeding box 7, driving the reduction motor 8, which is transmitted through the pulley 9 and belt 10, causing the central tube 17 to rotate. This causes the central tube 17 to drive the auger blades 12 to rotate, thereby moving the raw materials inside the porous sleeve 16. The air pump 15 is driven to heat the gas through the heating tube 11 and then deliver it into the central tube 17, so that the hot air is discharged from the holes of the central tube 17, thereby drying the raw materials inside the porous sleeve 16. The hot air removes moisture, thus ensuring the dryness of the raw materials. The rotation of the auger blades 12 allows for continuous conveying of the raw materials, thereby continuously drying them.
