Description

Technical Field

[0001] The utility model relates to the field of PE pipeline preparation equipment, in particular to a high-strength PE pipeline production and preparation device. Background Art

[0002] Polyethylene, referred to as PE, is a thermoplastic resin made by polymerizing ethylene. PE pipe is a pipe made of PE material.

[0003] In the production process of existing PE pipes, polyethylene and masterbatch particles need to be evenly mixed to form raw materials. The raw materials are pushed to the extruder through the auger, melted at high temperature in the extruder and extruded from the extruder mold; then the new material is bonded to the traction tube, and the new material is sized by the sizing sleeve, shaped by the vacuum box, sprayed by the cold water tank, and finally cut to a fixed length by the cutting mechanism. However, in actual use, it is found that polyethylene particles are easy to stick together to form particle blocks after being placed for a long time. The high-temperature melting effect of the stuck particle blocks is not good. There is a situation where the outer layer particles are melted and the inner layer particles are not melted, which affects the molding quality of the PE pipe.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to improve or solve the technical problem of polyethylene particles sticking together and affecting the quality of PE pipe molding in the prior art, the utility model provides a high-strength PE pipe production and preparation device.

The stirring mechanism includes a fixed stirring blade, a mounting ring, a rotating stirring blade and a power source. A driving gear is provided on the power source, and a driven gear is provided on the mounting ring. The power source drives the mounting ring to rotate, and then drives the rotating stirring blade to rotate, breaking up the large particle blocks in the raw materials to prevent the large particle blocks from being completely melted when melted at high temperature. At the same time, the fixed stirring blade is fixed in the bucket body, and the raw materials that are difficult to break up or adhere to the rotating stirring blade can be cleared and broken up by the shear force between the fixed stirring blade and the rotating stirring blade, thereby reducing the output power of the power source and ensuring the normal use of the stirring mechanism.

[0007] Furthermore, a mounting groove is provided on the bucket body, and a guide block for limiting the rotation trajectory of the mounting ring is arranged in the mounting groove; the mounting ring is rotatably arranged in the mounting groove, and a guide groove matching the guide block is provided on the mounting ring.

[0008] Furthermore, a plurality of guide blocks are evenly and spacedly arranged along the circumference of the mounting ring.

[0009] Furthermore, a sealing ring is arranged on the mounting ring to close the mounting groove.

[0010] Furthermore, the sealing ring is arranged on the upper and lower sides of the mounting ring.

[0011] Furthermore, a mounting seat for mounting the power source and a shell for protecting the power source are arranged on the bucket body.

[0012] Furthermore, the rotating stirring blade is detachably connected to the mounting ring.

[0013] Furthermore, the mounting ring is provided with an inserting groove matching the rotating stirring blade, and a locking groove is arranged opposite to the inserting groove; one end of the rotating stirring blade is inserted in the inserting groove, and the other end is fixed in the locking groove by bolts.

[0014] In summary, compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) By setting a stirring mechanism, the stirring mechanism includes a fixed stirring blade, a mounting ring, a rotating stirring blade and a power source. The power source is provided with a driving gear, and the mounting ring is provided with a driven gear. The power source drives the mounting ring to rotate, and then drives the rotating stirring blade to rotate, so as to break up the large particles in the raw material, avoid the large particles from not being completely melted when melting at high temperature, and ensure the molding quality of the PE pipe;

[0016] (2) By setting the guide block and the sealing ring, the guide block can limit the rotation direction of the mounting ring to prevent the mounting ring from being separated from the power source; the sealing ring can prevent the raw material from entering the mounting groove and prevent the raw material from affecting the power source to drive the mounting ring to rotate, thereby ensuring the normal use of the stirring mechanism.

Figure 1 As shown, in one or more embodiments, the utility model provides a high-strength PE pipe production and preparation device including a feed hopper and a conveying auger 3. The feed hopper includes a hopper body 1 and a stirring mechanism 2.

[0026] Continue to see Figure 1 In one or more embodiments, the bucket body 1 is roughly funnel-shaped, wide at the top and narrow at the bottom, with the top suitable for connecting to the feed pipe and the bottom connected to the conveying auger 3. Furthermore, a mounting groove 11 is provided on the inner wall of the bucket body 1, and the mounting groove 11 is provided in a circle along the circumference of the bucket body 1. A guide block 12 is arranged in the mounting groove 11, and the guide block 12 is arranged along the circumference of the mounting groove 11. Specifically, a plurality of guide blocks 12 are evenly and spacedly arranged along the circumference of the mounting groove 11, and each guide block 12 is roughly arc-shaped. Alternatively, one guide block 12 is provided, and is arranged in a ring shape.

[0027] Figure 2 yes Figure 1 The enlarged schematic diagram of A in the figure. Figure 1 and Figure 2As shown, in one or more embodiments, the stirring mechanism 2 includes a fixed stirring blade 21 fixedly mounted on the bucket body 1, a mounting ring 22 rotatably mounted in the bucket body 1, a rotating stirring blade 23 fixed on the mounting ring 22, and a power source 24 for driving the mounting ring 22 to rotate. Specifically, the fixed stirring blade 21 is arranged below the rotating stirring blade 23. The fixed stirring blade 21 is roughly rectangular plate-shaped and extends along the diameter direction of the bucket body 1. Both ends of the fixed stirring blade 21 are fixed on the bucket body 1. Exemplarily, both ends of the fixed stirring blade 21 are welded and fixed on the bucket body 1. Further, the mounting ring 22 is rotatably arranged in the mounting groove 11. Specifically, the mounting ring 22 is roughly annular, and a guide groove 222 matching the guide block 12 is opened at the bottom of the mounting ring 22, and the guide groove 222 surrounds the circumference of the mounting ring 22. Further, a sealing ring 223 is arranged on the mounting ring 22. Specifically, the sealing ring 223 is arranged on the upper and lower sides of the mounting ring 22. The mounting ring 22 cooperates with the sealing ring 223 to close the mounting groove 11 to prevent the raw material from entering the mounting groove 11. At the same time, the arrangement of the sealing ring 223 can reduce the vibration of the mounting ring 22 in the mounting groove 11. Further, a driven gear 221 is arranged on the circumferential outer side of the mounting ring 22 so as to be connected to the power source 24. Further, the mounting ring 22 forms a detachable connection with the rotating stirring blade 23. Specifically, a plug-in groove and a locking groove 224 are provided on the mounting ring 22. The plug-in groove and the locking groove 224 are arranged symmetrically with respect to the center of the mounting ring 22. The plug-in groove is a roughly long strip groove, and matches the rotating stirring blade 23, and one end of the rotating stirring blade 23 can be inserted into the plug-in groove. The top and left sides of the locking groove 224 are both open, so that the other end of the rotating stirring blade 23 is placed in the locking groove 224, and then fixed in the locking groove 224 by bolts, so that the rotating stirring blade 23 and the mounting ring 22 form a detachable fixed connection. Alternatively, the rotating stirring blade 23 and the mounting ring 22 can be fixedly connected by welding. It is understandable that the sealing ring 223 is interrupted at the locking groove 224. Further, the power source 24 is a motor. A driving gear 241 meshing with the driven gear 221 is arranged on the output shaft of the power source 24. The power source 24 rotates, driving the driving gear 241 to rotate, and then driving the mounting ring 22 to rotate. Specifically, a mounting seat 242 for mounting the power source 24 and a shell 243 for protecting the power source 24 are also arranged on the bucket body 1. The mounting seat 242 is fixedly connected to the bucket body 1 by welding. A through groove connected to the mounting groove 11 is also arranged on the bucket body 1, and the driving gear 241 meshes with the driven gear 221 through the through groove.

[0028] Continue to see Figure 1 and Figure 2The conveying auger 3 is arranged below the feed hopper, one end of the conveying auger 3 is connected to the feed hopper, and the other end is connected to the extruder. The raw material is conveyed into the feed, and after being broken up by the rotating stirring blade 23 and the fixed stirring blade 21, it falls into the conveying auger 3; then it is conveyed to the extruder driven by the conveying auger 3, and is melted and extruded at high temperature in the extruder.
