Description

Technical Field

[0001] The invention belongs to the technical field of polymer raw material conveying, in particular to a high molecular polymer processing raw material conveying device. Background Art

[0002] High molecular weight polymer refers to a high molecular weight compound formed by repeated bond connection. It includes crystalline structure, amorphous structure, oriented structure and woven structure. With the emergence of different types of high molecular weight polymers, subsequent polymer recycling is also a major problem. When recycling waste plastic polymers, the existing technology process will recycle and crush the waste plastic polymers as raw materials, and then heat and melt them with two or more different raw materials in the required proportion, and then transport them to the extruder, use the extruder to extrude and granulate, and process them into new high molecular weight polymers.

[0003] At present, when waste plastic polymers are recycled and processed into new high-molecular polymers, they are first crushed by a crusher, and then a belt conveyor mechanism is used to receive the crushed waste plastic polymers under the crusher and convey them into a heating tank. After two or more different waste polymers are all conveyed into the heating tank, the feeding port of the heating tank is closed and the heating system is opened to heat and melt the waste polymers inside, and at the same time, they are stirred to make them evenly mixed, thereby forming a high-molecular polymer with a new structure.

[0004] There are still some problems in the prior art. A belt conveyor mechanism is usually used to receive the crushed polymer discharged from the bottom of the crusher. Although the belt conveyor mechanism receives the conveyed material relatively stably, it is limited by its own structure and feeding method. It must maintain a certain inclination angle to stably convey its raw materials into the heating tank. If the inclination angle does not meet the standard, a large amount of polymer will leak from both sides of the belt conveyor mechanism. Moreover, even if the conveying angle meets the standard, the raw materials conveyed at one time will be limited by the width of the belt conveyor mechanism, which will affect the efficiency of raw material transportation, so that the overall use value cannot be maximized.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0022] like Figures 1 to 7 As shown, a polymer processing raw material conveying device according to an embodiment of the present invention comprises a heating mixing tank 1, an extruder 3 and a control box 2 installed outside the heating mixing tank 1, a feed opening 29 is provided at the lower end of the heating mixing tank 1, and the feed opening 29 is fixedly connected to the extruder 3, a fixing sleeve 9 is fixedly connected to the outside of the heating mixing tank 1, and a raw material conveying component 8 is installed in the inner cavity of the fixing sleeve 9; The raw material conveying assembly 8 includes a conveying conduit 81 installed in the inner cavity of the fixed sleeve 9, the inner cavity of the conveying conduit 81 is rotatably connected to a conveying auger 82, and the outer portion of the conveying conduit 81 is provided with a material receiving port 85 for receiving and guiding the raw materials into the inner cavity of the conveying conduit 81; A servo motor 5 is installed on the upper end surface of the heating mixing tank 1 , and a rotating column 20 is fixedly connected to the output shaft end of the servo motor 5 . The rotating column 20 is located outside the inner cavity of the heating mixing tank 1 and is fixedly connected to a stirring frame 21 .

[0023] Specifically, in the prior art, a belt conveyor mechanism is usually used to convey the polymer raw materials into the heating tank. However, due to the limitations of its own structure and feeding method, the belt conveyor mechanism can only maintain a certain tilt angle to stably convey its raw materials into the heating tank. In addition, in order to prevent the raw materials from leaking from both sides of the conveyor belt during the conveying process, only a small amount of raw materials can be conveyed at a time, resulting in the need to convey two different raw materials into the heating tank in sequence before the feeding port can be closed to mix, heat and melt them. During this idle period of feeding, the processing efficiency of the high molecular polymer is wasted, so that the overall use value cannot be reflected to the maximum extent. The present invention puts the crushed polymer into the receiving port 85, and drives the conveying auger 82 to rotate at the same time, so that the conveying auger 82 twists the polymer to convey it upward. After the polymer is conveyed to the top of the inner cavity of the conveying conduit 81, it will be discharged into the heating mixing tank 1, and then the control box 2 is used to start the heating mixing tank 1 to heat and melt the polymer in the inner cavity. At the same time, the servo motor 5 is started to drive the rotating column 20 to rotate, and then the stirring frame 21 is driven to stir and mix the polymer raw materials in the inner cavity of the heating mixing tank 1. The mixed, heated and melted polymer raw materials are discharged into the extruder 3 through the discharge port 29, and the extruder 3 is used to stir the melted polymer raw materials for the second time, and extrusion granulation is performed through the discharge port of the extruder 3, thereby realizing the rapid processing and production of high molecular polymers, thereby solving the problem that the existing polymer raw material conveying device has low conveying efficiency and is also limited by the site because the belt conveying mechanism can only stably convey its raw materials into the heating tank under the condition of maintaining a certain inclination angle.

[0024] like Figure 1 and Figure 6 As shown, the upper end surface of the heating mixing tank 1 is provided with a plurality of feeding ports 12 , and a storage barrel 6 is installed outside the plurality of feeding ports 12 , and a discharge pipe 83 is fixedly connected to the outside of the conveying conduit 81 , and the discharge pipe 83 is connected to the storage barrel 6 .

[0025] like Figure 1 and Figure 6As shown, a crushing box 10 is fixedly connected to the outside of the heating mixing tank 1, a crushing roller 11 is arranged in the inner cavity of the crushing box 10, and a material receiving pipe 84 is fixedly connected to the lower end surface of the crushing box 10. The end of the material receiving pipe 84 away from the crushing box 10 is fixedly connected to the material receiving port 85.

[0026] Specifically, when processing high molecular polymers, the polymer raw materials are put into the crushing box 10, and the two crushing rollers 11 are driven to rotate at the same time, and then the polymer raw materials are crushed. The lower end of the crushing box 10 is connected to a receiving pipe 84, and then the crushed polymer raw materials are guided into the receiving port 85 and into the conveying conduit 81. Then, the polymer raw materials are twisted by driving the conveying auger 82 to move to the top of the inner cavity of the conveying conduit 81, and are conveyed to the discharge pipe 83, so that they fall into the storage barrel 6 for temporary storage. When it is necessary to replenish the polymer raw materials in the heating mixing tank 1, the polymer raw materials can be quickly replenished by opening the feeding port 12, which solves the problem that the existing polymer raw material conveying device usually needs to crush different polymer raw materials into particles in advance when processing and preparing high molecular polymers, and then use the conveying mechanism to convey the polymer raw materials into the heating tank for mixing, heating and melting, so as to improve the production efficiency of the high molecular polymer. However, when adding polymer raw materials to the heating tank, the heating tank needs to be stopped and the feeding port needs to be opened to add polymer raw materials, thereby affecting the production efficiency of the high molecular polymer.

[0027] like Figures 1 to 7 As shown, the inner cavity of the feeding port 12 is provided with an automatic feeding assembly, and the automatic feeding assembly includes a sealing cover 13 rotatably connected in the inner cavity of the feeding port 12 , a rotating shaft 14 is fixed inside the sealing cover 13 , and the rotating shaft 14 is rotatably connected to the heating mixing tank 1 .

[0028] like Figure 1 , Figure 3 and Figure 6 As shown, a rotating groove 17 is opened inside the upper end of the heating mixing tank 1, and the rotating shaft 14 is rotatably connected in the inner cavity of the rotating groove 17, and the rotating shaft 14 is located outside the inner cavity of the rotating groove 17 and is slidably clamped with a fixed plate 15, and a torsion spring 16 is fixedly connected to one end surface of the fixed plate 15, and one end of the torsion spring 16 is fixedly connected to the inner wall of the rotating groove 17.

[0029] like Figure 1 , Figure 3 and Figure 6 As shown, a threaded sleeve 19 is slidably connected to the outside of the rotating shaft 14, and the threaded sleeve 19 is threadedly connected to the heating mixing tank 1. The threaded sleeve 19 is located at one end of the inner cavity of the rotating groove 17 and is rotatably connected to a contact plate 18, and the contact plate 18 is used to contact the fixed plate 15.

[0030] Specifically, in the prior art, a conveying mechanism is usually used to directly convey the polymer raw material into the heating tank. Since the amount of the polymer raw material conveyed into the heating tank is difficult to control and the heating tank needs to be shut down, the polymer raw material conveyed into the heating tank exceeds the predetermined standard, which affects the mixing, heating and melting time. The operator needs to use the control box to adjust the heating temperature again, which is not only cumbersome, but also affects the processing efficiency of the polymer. When the polymer raw material is added to the heating mixing tank 1, the crushed polymer raw material is conveyed into the inner cavity of the storage barrel 6 by using the conveying conduit 81. As the polymer raw material in the inner cavity of the storage barrel 6 increases, the sealing cover 13 is overturned by the weight of the polymer raw material, thereby driving the rotating shaft 14 to rotate. At the same time, the rotating shaft 14 drives the fixed press 15 to rotate, and then opens the feeding port 12 to discharge the polymer raw material in the inner cavity of the storage barrel 6. After the polymer raw material is discharged, the torsion spring 16 twists the fixed disk 15 to drive the rotating shaft 14 to rotate, and the rotating shaft 14 drives the sealing cover 13 to slowly The feeding port 12 is flipped and reset to seal, thereby realizing quantitative feeding of polymer raw materials when refilling the heating mixing tank 1. When the amount of polymer raw materials fed needs to be adjusted, the threaded sleeve 19 is twisted to push the abutment plate 18 into the inner cavity of the rotating groove 17, and then the abutment plate 18 abuts against the fixed plate 15 and pushes the fixed plate 15 to squeeze the torsion spring 16, thereby increasing the torsion force of the torsion spring 16, thereby increasing the weight of the polymer raw materials borne by the sealing cover 13, achieving the effect of increasing the amount of polymer raw materials fed, thereby solving the above-mentioned problem. Embodiment 2

[0031] like Figure 1 , Figure 2 and Figure 7 As shown, a transmission assembly 7 is provided on the upper end surface of the heating mixing tank 1, and the transmission assembly 7 includes a base 72 fixedly connected to the upper end surface of the heating mixing tank 1, a support column 71 is installed on the upper end surface of the base 72, a transmission shaft 75 is rotatably connected inside the support column 71, and both ends of the transmission shaft 75 pass through the support column 71 and the base 72 and are fixedly connected with a transmission sprocket 74, the transmission sprocket 74 is externally transmission-connected with a first chain 73, and the first chain 73 is transmission-connected to the rotating column 20.

[0032] like Figure 2 , Figure 4 and Figure 7 As shown, the transmission sprocket 74 is externally transmission-connected to two second chains 76, and one end of the two second chains 76 is transmission-connected to a driven sprocket 77, the driven sprocket 77 is fixedly connected to the conveying auger 82, and the rotating column 20 is located outside the inner cavity of the heating mixing tank 1 and is fixedly connected to a scraper 23.

[0033] Specifically, when processing high molecular polymers, the servo motor 5 is started to drive the rotating column 20 to rotate, and the rotating column 20 drives the first chain 73 to rotate, and then drives the transmission sprocket 74 to rotate, and at the same time, the transmission sprocket 74 drives the transmission shaft 75 to rotate, and the transmission shaft 75 will drive the transmission sprocket 74 to rotate during the rotation process, and at the same time, the transmission sprocket 74 drives the two second chains 76 to rotate, and then drives the driven sprocket 77 to rotate, and then drives the conveying auger 82 to rotate, and then the polymer raw material is wrung and conveyed into the heating mixing tank 1, and falls onto the unloading partition 22 in the heating mixing tank 1, and the rotating column 20 will also drive the scraper 23 to rotate during the rotation process, and make the scraper 23 move the unloading The polymer raw material on the partition 22 is mixed for the second time after the scraper 23 rotates, and at the same time, it is evenly scattered into the heating mixing tank 1 through the holes on the blanking partition 22, thereby effectively improving the efficiency of melting the polymer raw material and improving the efficiency of mixing the polymer raw material. This solves the problem that when the existing polymer raw material conveying device is used to process the polymer, it is inconvenient to disperse the polymer raw material into the heating tank because the polymer raw material is directly conveyed into the heating tank by the conveying mechanism, resulting in the polymer being concentrated in the heating tank. The heating tank needs to be stirred for a long time to achieve the uniformity of mixing, thereby affecting the production efficiency of the polymer.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, a material discharge baffle 22 is installed in the inner cavity of the heating mixing tank 1 , and an air guide groove 28 is opened on the inner wall of the heating mixing tank 1 . The air guide groove 28 is used to guide and discharge the waste gas in the heating mixing tank 1 .

[0035] like Figure 4 , Figure 5 and Figure 6 As shown, the outside of the heating mixing tank 1 is located in the inner cavity of the air guide groove 28 and is fixedly connected to an exhaust pipe 4. The exhaust pipe 4 is arranged in an "S" shape and is rotatably connected to an impeller 24 at the "S"-shaped turning point of the inner cavity. A generator 25 is installed at the upper end of the exhaust pipe 4, and the power generation shaft of the generator 25 is fixedly connected to the impeller 24. An exhaust port 27 is opened at one end of the exhaust pipe 4, and a filter plug 26 is inserted into the inner cavity of the exhaust port 27. The filter plug 26 is made of honeycomb activated carbon.

[0036] Specifically, when the device is in operation, the polymer raw materials in the mixing tank 1 are heated to generate high-temperature air pressure, and the high-temperature air pressure will be discharged into the exhaust pipe 4 through the air guide groove 28. Since the exhaust pipe 4 is arranged in an "S" shape and is rotatably connected to the impeller 24 at the "S"-shaped turning point of the inner cavity, when the high-temperature air pressure flows along the "S"-shaped inner cavity, it will impact the impeller 24 to rotate rapidly. At the same time, the impeller 24 drives the generator shaft of the generator 25 to rotate and generate electricity, and the exhaust gas that blows the impeller 24 to rotate will rush into the filter plug 26, and after being filtered by the filter plug 26, it will be discharged through the exhaust port 27, thereby improving the utilization rate of energy.

[0037] Working principle: when processing high molecular polymer, the polymer raw material is put into the crushing box 10, and the two crushing rollers 11 are driven to rotate at the same time, and then the polymer raw material is crushed. The lower end of the crushing box 10 is connected to the material receiving pipe 84, and then the crushed polymer raw material is guided into the material receiving port 85 and into the conveying conduit 81; Then, the servo motor 5 is started to drive the rotating column 20 to rotate, and the rotating column 20 drives the first chain 73 to rotate, and then drives the transmission sprocket 74 to rotate, and the transmission sprocket 74 drives the transmission shaft 75 to rotate. During the rotation process, the transmission shaft 75 will drive the transmission sprocket 74 to rotate, and the transmission sprocket 74 drives the two second chains 76 to rotate, and then drives the driven sprocket 77 to rotate, and then drives the conveying auger 82 to rotate, and then twists the polymer raw material to be transported into the heating mixing tank 1, and falls onto the unloading partition 22 in the heating mixing tank 1. During the rotation process, the rotating column 20 will also drive the scraper 23 to rotate, and the scraper 23 moves the polymer raw material on the unloading partition 22, so that the polymer raw material on the unloading partition 22 is secondary mixed after the scraper 23 rotates, and at the same time, it is evenly scattered into the heating mixing tank 1 through the holes on the unloading partition 22, thereby effectively improving the efficiency of melting the polymer raw material and the efficiency of mixing the polymer raw material; When the device is in operation, the polymer raw materials in the mixing tank 1 are heated to generate high-temperature air pressure, and the high-temperature air pressure will be discharged into the exhaust pipe 4 through the air guide groove 28. Since the exhaust pipe 4 is arranged in an "S" shape and is rotatably connected to the impeller 24 at the "S"-shaped turning point of the inner cavity, when the high-temperature air pressure flows along the "S"-shaped inner cavity, it will impact the impeller 24 to rotate rapidly. At the same time, the impeller 24 drives the generator shaft of the generator 25 to rotate and generate electricity, and the exhaust gas that blows the impeller 24 to rotate will rush into the filter plug 26, and after being filtered by the filter plug 26, it will be discharged through the exhaust port 27, thereby improving the utilization rate of energy.
