A production mold for concrete pipe pouring that can recover the heat of hydration

Abstract

The invention discloses a concrete pipeline pouring production mold capable of recovering heat of hydration, comprising: a pouring mold, a fixed support is arranged at the bottom, a pouring opening is arranged at the top, and heat-conducting side walls are arranged on both inner and outer sides; a heat exchange chamber, It is arranged on the outer side of the heat-conducting side wall, and heat-conducting fins are evenly arranged in the middle, and an exchange hole is arranged in the middle of the heat-conducting fin, and a heat exchange tube is arranged in the middle of the exchange hole; an insulated water tank. The present invention can conduct a large amount of heat released by the hydration reaction of concrete during pouring to the outer heat exchange chamber through the heat conduction side walls arranged on both the inside and outside sides of the pouring mold, and transfer the heat through the heat conduction tubes arranged in the heat exchange chamber. It is convenient for subsequent use by transferring and storing in the heat preservation water tank in the middle. At the same time, because the heat is absorbed and transferred, the concrete is cooled to a large extent, which makes the heat dissipate more evenly, and avoids unbearable temperature stress in the pouring body, resulting in the whole block Cracks appear in the concrete.

Description

technical field [0001] The invention relates to concrete pipeline production equipment, in particular to a concrete pipeline pouring production mold capable of recovering hydration heat. Background technique [0002] Concrete pipes generally refer to pipes produced by pouring concrete. The production methods generally include centrifugal method, vibration method, rolling method, vacuum operation method, rolling, centrifugal and vibration combined action method, etc. In order to improve the performance of concrete pipes, China Compared with steel pipes, concrete pipes can save a lot of steel, prolong the service life, and have less investment in plant construction, convenient laying and installation, and have been widely used in factories, mines, oil fields, ports, and cities. It is widely used in construction and farmland water conservancy projects.

AI Technical Summary

Problems solved by technology

The applicant found that when pouring and producing concrete pipes with a large volume, a large amount of heat will be released due to the hydration reaction of the concrete, and the heat of the cement thermal reaction of large concrete products will dissipate unevenly, resulting in unbearable heat in the pouring body. Temperature stress leads to cracks in the whole concrete, so delaying the heat release process of concrete is an important feature. Generally, it is necessary to add a certain amount of concrete heat release moderator, but this will prolong the setting time of concrete and reduce production efficiency. At the same time, the heat released is also dissipated and wasted.
