Heat preservation steel pipe polyurethane heat preservation layer manufacturing and processing system

Abstract

The invention relates to a heat preservation steel pipe polyurethane heat preservation layer manufacturing and processing system which comprises a base, positioning and clamping mechanisms, a driving mechanism, a pouring mechanism and a top plate, the positioning and clamping mechanisms are installed above the base and evenly distributed in the circumferential direction of the base, and the pouring mechanism is arranged above the positioning and clamping mechanisms. The top plate is mounted between the positioning and clamping mechanisms and the pouring mechanism, and the driving mechanism is mounted in the middle of the base. According to the system, the design concept of a combined preparation structure is adopted for processing of polyurethane heat preservation steel pipes, the arranged driving structure can achieve detachable separation of the pouring mechanism and the positioning and clamping mechanisms. The system can be suitable for machining heat preservation steel pipes of different lengths, on the basis, the arranged annular positioning and clamping mechanisms can achieve simultaneous processing of a plurality of heat preservation steel pipes, and then the manufacturing and processing speed of the heat preservation steel pipes is increased.

Description

technical field [0001] The invention relates to the field of steel pipe processing machinery, in particular to a production and processing system for polyurethane insulation layers of heat-retaining steel pipes. Background technique [0002] Polyurethane thermal insulation steel pipe is also called thermal insulation direct buried pipe. It is composed of working steel pipe for conveying medium, foam insulation layer and polyethylene plastic outer protection pipe, which are combined outwards through equipment in sequence. Polyurethane thermal insulation steel pipe has low engineering cost and low heat loss. It has the advantages of less energy consumption, good insulation performance, long service life, less land occupation, fast construction, favorable environmental protection and high safety. It is very popular among people. It is required that the insulation layer of the insulation steel pipe and the insulation shell have a high degree of tightness, no gaps or cavities sho...

AI Technical Summary

Problems solved by technology

[0007] The present invention can solve the problem that the heat preservation layer of the existing steel pipe is not concentric with the steel pipe, the tightness between the heat preservation shells is low, and the heat preservation effect cannot be achieved. It is easy to pour evenly because the length of the insulation pipe is too long, and it is easy to have gaps or cavities. Common processing machines process one diameter of insulation steel pipe at a time. The use of machinery is easily limited by the diameter, and the processing efficiency of the production and processing machinery is relatively low. low level problem
