[0002] PPH is a high molecular weight homopolypropylene. After β modification, the material has a uniform and delicate Beta crystal structure. It not only has excellent chemical resistance, high and low temperature resistance, creep resistance, and an operating temperature of 100°C, but also has the advantages of non-toxicity, light weight, and easy transportation and installation. It is a high-quality product that is more resistant to high temperatures, corrosion, and aging than PP pipes. According to the characteristics of PPH materials, PPH materials are mixed with masterbatches in a certain ratio, and then through extrusion, winding, molding, cutting, welding, assembly and other steps, it can be made into PPH liquid storage tanks, which are economical and durable, reduce equipment maintenance, and extend service life, and have superior performance. In the process of mixing PPH materials and masterbatches, the uniformity of the mixing has a great influence on the color and quality of the storage tank. However, currently, when mixing PPH raw materials and masterbatches, most of the mixing devices use a closed hopper with a stirring shaft, and only a few stirring rods are arranged on the stirring shaft for stirring and mixing. The mixing efficiency and mixing effect need to be improved. Therefore, the present application specifically proposes a raw material mixing device for PPH liquid storage tank production, which is used to improve the stirring rate and stirring effect.

DETAILED DESCRIPTION
[0017] The following is combined with Figure 1-5 The specific implementation methods of the utility model are further described in detail.
[0018] Embodiment 1, the technical solution is that, when the present application is used, an appropriate amount of PPH raw material and masterbatch are fed into the mixing tank 1 through the feed pipe 4 in a corresponding proportion, the motor 3 is started to drive the stirring shaft 2 to rotate so that the mixing device 6 works, and then the materials in the mixing tank 1, namely the PPH raw material and the masterbatch, are mixed and stirred. During the rotation of the stirring shaft 2, the mixing device 6 rotates with it, and the large gear 10 and the ring gear will also interact with each other to cause the vertical shaft 9 to rotate. The rotation of the vertical shaft 9 will drive the cross bar 12 to rotate through the cooperation of the large bevel gear 11 and the small bevel gear 13, and then the stirring rod 14 on the cross bar 12 will also rotate to stir the material. Multiple groups of cross bars 12 are arranged vertically together with the stirring rods 14, and the upper stirring rods 14 are staggered with the stirring rods 14 below them, thereby greatly increasing the stirring area of the stirring rods 14 and improving the stirring and mixing efficiency. The stirring rods 14 have a large working range, which greatly improves the mixing effect and makes the materials mixed evenly. The large bevel gear 11 and the small bevel gear 13 are installed in the installation cylinder 8 to prevent materials from getting stuck in their meshing parts during the material mixing process, thereby affecting their normal operation.
[0019] Embodiment 2, based on embodiment 1, specifically, when the present application is in use, when the stirring shaft 2 rotates under the drive of the motor 3, the mixing device 6 rotates together with it. During the rotation process, the large gear 10 interacts with the large gear ring 5 to rotate the vertical shaft 9. The rotation of the vertical shaft 9 drives the cross bar 12 to rotate together with the stirring rod 14 through the cooperation of the large bevel gear 11 and the small bevel gear 13, so that the stirring rod 14 can stir the materials at different levels, with a wide stirring range, high efficiency and good stirring effect. The interior of the mounting cylinder 8 fixedly connected to the connecting rod 7 is a cavity structure, and the large bevel gear 11 and the small bevel gear 13 are arranged in the cavity to avoid being affected by the material and unable to work normally. There is a speed difference between the large bevel gear 11 and the small bevel gear 13. When the large bevel gear 11 rotates with the vertical shaft 9, the small bevel gear 13 can make the cross bar 12 rotate at a faster speed, so that the stirring shaft 2 on the cross bar 12 can violently interact with the material to ensure the mixing effect. The cross bar 12 is arranged radially along the stirring shaft 2.
[0020] Embodiment 3, based on embodiment 2, after the materials are mixed, the discharge valve 16 can be opened and the feeding screw 18 at the conveying cylinder 17 can be started, and the materials will move to the discharge port 19 of the conveying cylinder 17 through the discharge pipe 15 under the action of the feeding screw 18, and be discharged from the discharge port 19. The support legs 20 provided provide support for this application.
