Problems solved by technology

[0003] In addition, as far as the existing pipe forming process and forming equipment are concerned, only a single pipe can be processed, and in the process of processing, the energy consumed - heat energy is relatively high, and the waste gas generated seriously pollutes the surrounding environment and endangers the health of operators , therefore, it is absolutely necessary to study new pipe forming process and forming equipment to reduce energy consumption, improve the working environment and ensure the health of the staff

Embodiment 1

[0035] The molding process of the hollow sound-absorbing pipe provided by the present invention comprises the following steps:

[0036] 1. Mixing of raw materials: fully mix the required raw materials according to the existing formula;

[0037] 2. Heat forming:

[0038] A. After feeding the mixed material into the conical twin-screw shown in Figure 5, under the condition that the screw rotation speed is 20 rpm, it is passed through in turn: the first zone (A) 185 ° C, the second zone (B) 175 ℃, zone 3 (C) 170°C, zone 4 (D) 160°C, heating and extruding for 10 minutes, then stop heating in zone 3 and zone 4, and maintain plasticization by the heat generated by the shear stress of the conical twin-screw 11 temperature, to reduce power consumption, while heating the exhaust gas produced during the extrusion process, through the exhaust through hole 10 on the conical twin-screw and the connecting pipe, it is sent to the exhaust gas recovery device for processing and recovery, and ...

Embodiment 2

[0045] The molding process of the hollow sound-absorbing pipeline provided by the present invention, its thermoforming is:

[0046]A. After feeding the mixed material into the conical twin-screw shown in Figure 5, under the condition that the screw rotation speed is 40 rpm, it passes through in turn: the first zone (A) 195 ° C, the second zone (B) 185 ℃, zone 3 (C) 180°C, zone 4 (D) 170°C, heating and extruding for 5 minutes, then stop heating in zone 3 and zone 4, and maintain plasticization by the heat generated by the shear stress of the conical twin-screw 11 temperature, to reduce power consumption, while heating the exhaust gas produced during the extrusion process, through the exhaust through hole 10 on the conical twin-screw and the connecting pipe, it is sent to the exhaust gas recovery device for processing and recovery, and then emptied;

[0047] B. The raw material heated and plasticized by the conical twin-screw directly enters the forming mold, firstly conducts a ...

Abstract

The present invention provides a hollow sound absorbing pipeline and its moulding process and equipment. The mouth film of the moulding has a secondary distributaries return frame to make raw material polymerizing and pump via secondary distributaries after via first distributaries polymerizing, so as to form hollow sound absorbing hole on the wall of the pipeline along the pipeline axes. The hollow sound absorbing pipeline can absorb noise generated by rapid flow speed of the flowing material in the pipeline, effectively eliminates the pollution caused by the noise, and makes inner wall of the single pipe smooth, the flowing material in the pipe can smoothing flow and can not form pipe plug, since setting axial hole on the wall of the single pipe, the pipeline has a less material, lower cost, and high strength. The invention effectively recovers harmful gas generated by the process, gets at the root of harm of the waste gas to environment and workers, in addition, the process of the invention can reduce electricl energy consumption and saves cost.

Description

technical field [0001] The invention relates to a pipe, its processing method and processing equipment, in particular to a hollow sound-absorbing pipe, its forming process and forming equipment. Background technique [0002] With the development of science and technology and the improvement of people's material living standards, not only the living conditions are required to be improved and improved, such as living in a spacious and bright house, but also the living and working environment is required to be good, the air is fresh, clean, smoke-free, Exhaust gas, dust pollution, no noise pollution. The noise mainly refers to the noise generated by the flowing objects in the pipes of factories or buildings. As far as the current conveying pipeline is concerned, most of them are single pipes. When they are conveying fluid objects, they will generate a lot of noise, and this noise will be transmitted almost without reservation, causing noise pollution to the surrounding environ...
