Description

Technical Field

[0001] The utility model relates to the technical field of plastic equipment, in particular to high modulus polypropylene HMPP production equipment. Background Art

[0002] Polypropylene is a general-purpose thermoplastic with a wide range of applications. The density of polypropylene is 0.89-0.91 g / cm 3 , good mechanical balance, operating temperature range is -20 ~ 140 ℃, below 80 ℃ can resist the corrosion of acid, alkali, salt solution and various organic solvents. Due to its good applicability and versatility, it is widely used in chemical production, such as storage tanks, reactors, air ducts and other equipment.

[0003] At present, polypropylene equipment generally adopts the extrusion winding process to form an integral body. The tank body has no welds, and the strength (especially stiffness) and overall structural stress are greatly improved, which effectively improves the safety performance of the equipment. For example, a polypropylene reactor disclosed in Chinese patent CN213824782U includes a polypropylene reactor body and other structures. The polypropylene reactor has high installation strength and is safe and reliable to use. However, compared with metal equipment, the strength of existing polypropylene equipment is still significantly different. Therefore, many equipments use composite materials such as polypropylene and steel mesh (steel belt), glass fiber, glass fiber mesh layer or glass fiber reinforced outer layer. However, due to the large difference in thermal shrinkage of different materials, the interface layers are easy to peel and delaminate, and the composite scraps and waste equipment are difficult to recycle, which restricts its use scenario. Therefore, a high modulus polypropylene HMPP production equipment is proposed to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2The utility model provides the following technical solutions: a high modulus polypropylene HMPP production equipment, including a cylinder 1, characterized in that: a lower head 2 is provided on one side of the cylinder 1, and an upper head 3 is provided on the other side of the cylinder 1, and the upper head 3 and the lower head 2 can be at least one of flat, conical or circular, a stirring port 4 is provided on one side of the upper head 3, and a spare port 5 and a functional port 6 are respectively provided on the outside of the upper head 3, a baffle 7 is provided inside the cylinder 1, and a discharge port 8 is provided on the outside of the cylinder 1.

[0021] The cylinder body 1 is composed of an inner layer 101 , an outer layer 102 and rib tubes 103 . The inner side of the outer layer 102 is wrapped with a plurality of rib tubes 103 , and the plurality of rib tubes 103 are spirally wound around the outer side of the inner layer 101 .

[0022] In addition, the inner layer 101 and the outer layer 102 are both high modulus polypropylene resin layers, the rib tube 103 is a reinforced rib tube corrugated structure with a hollow interior, and the outer layer 102, the inner layer 101 and the rib tube 103 are all integrally formed.

[0024] The working principle of this embodiment is as follows:

[0025] In usage scenarios with large temperature changes, because high modulus polypropylene is a thermoplastic material, the adhesion between the reinforced fin tube corrugated structure layer and the inner and outer layers is tighter, and this new type of plastic fin tube reinforced corrugated structure layer and the inner and outer layers are not easy to crack or delaminate due to temperature difference. Due to the significant corrosion resistance of high modulus polypropylene as a thermoplastic material, the service life is greatly extended to more than 50 years. It is very convenient to recycle and can be directly crushed and reused.
