PE steel-plastic composite water supply pipe and machining extrusion device thereof

Abstract

The invention discloses a PE steel-plastic composite water supply pipe and a machining extrusion device thereof. The PE steel-plastic composite water supply pipe comprises a water supply pipe body, wherein an annular plate is fixedly connected between the inner walls of the water supply pipe body; a screen plate is fixedly connected between the inner walls of the annular plate; and a rotating shaft is rotatably connected on the screen plate. The machining extrusion device of the PE steel-plastic composite water supply pipe comprises a feeding box; a device cavity and a feeding cavity are formed in the feeding box; a feeding port is formed in the portion, corresponding to the feeding cavity, at the upper end of the feeding box; and a motor is fixedly installed on the side wall of the feeding box. According to the PE steel-plastic composite water supply pipe and the machining extrusion device thereof, through the arrangement of a current generating mechanism, a driving mechanism, a resistor, a water pumping mechanism, a transmission mechanism and the like, power generation can be carried out by utilizing the power of water flow in the water supply pipe, so that the water supply pipebody and the water flow in the water supply pipe body are heated to prevent the freezing of the water supply pipe body; and cooling water can be continuously conveyed to a heat dissipation cavity by utilizing the power of the motor, so that the effect of rapid heat dissipation and cooling is achieved, and the production and machining efficiencies of the water supply pipe are further greatly improved.

Description

technical field [0001] The invention relates to the technical field of water supply pipes, in particular to a PE steel-plastic composite water supply pipe and a processing and extrusion device thereof. Background technique [0002] In the prior art, the traditional steel-plastic composite pipe is usually composed of a three-layer structure, that is, the middle layer is made of steel pipes, and the inner layer and the outer layer are covered with plastic pipes, or the middle layer is made of plastic pipes, and the inner layer and the outer layer are covered. Steel Pipe. The steel-plastic composite pipe combines the characteristics of steel and plastic. It can not only carry out the same construction as traditional steel pipes, but also has high strength and durability, and is cheaper than stainless steel pipes. It has been gradually applied to high-rise water supply, industrial water, mining. Pipelines, rainwater collection and transportation, etc. [0003] However, during ...

Problems solved by technology

[0003] However, during the long-term use of the water pipe, especially in the cold winter, when the environment is below zero, if the water in the water pipe does not flow or the temperature is low, the water in the water pipe will inevitably freeze. Frozen water pipes are unusable

If the water pipe is frozen, it will be very troublesome to thaw. Most households use hot water to thaw, but it is very slow to use hot water to thaw. It takes a long time and consumes more hot water. By ensuring that the inside of the water pipe For the flow of water, for the end close to the faucet, if the faucet is turned on for a long time, it is a waste of water resources and cannot be kept open for a long time

[0004] In addition, in the production and processing process of composite water supply, the raw materials need to be heated into a molten state, and then extruded into a tube through the extrusion device. The temperature of the water supply pipe just extruded from the extrusion device is relatively high. The existing technology is to make it naturally Air-cooled heat dissipation, this heat dissipation method has low heat dissipation efficiency, which will seriously affect the production and processing efficiency in the mass production process of water supply pipes
