Heat preservation type concrete stirring device

Abstract

The invention provides a heat preservation type concrete stirring device. The heat preservation type concrete stirring device comprises a stirring cylinder, a central stirrer, a first planetary stirrer, a second planetary stirrer and a driving mechanism; the outer side wall of the stirring cylinder sinks in the radial direction of the stirring cylinder to form an annular groove, a heating coil isarranged in the annular groove, a heat conduction insulating layer is arranged between the heating coil and the groove wall of the annular groove, and the stirring cylinder is further sleeved with aninsulation heat-insulation cylinder; the central stirrer and the stirring cylinder are coaxially arranged, and the central stirrer, the first planetary stirrer and the second planetary stirrer are arranged in parallel and are all connected with the driving mechanism; and the driving mechanism drives the central stirrer to rotate around the axis of the stirring cylinder, and further drives the first planetary stirrer to revolve around the axis of the stirring cylinder and rotate around the rotating axis of the first planetary stirrer. Therefore, the uniformity of final concrete can be effectively ensured, and the temperature equilibrium of the concrete can be ensured.

Description

technical field [0001] The invention relates to a stirring device, in particular to a thermal insulation concrete stirring device. Background technique [0002] Concrete is a commonly used building material. Concrete is formed by mixing sand, cement, gravel and water. Concrete mixing is realized by a mixer. The existing concrete mixer has the following defects: during the concrete mixing process, the The concrete near the stirring paddle can be fully stirred, but the concrete far away from the stirring paddle cannot be fully stirred, especially the coagulation near the side wall of the container of the mixer, often deposits, which seriously affects the quality of the concrete ; On the other hand, because the performance of concrete will be affected by temperature, the existing mixer cannot maintain the temperature of concrete, especially in a low-temperature environment. Too low temperature will cause concrete freeze-thaw damage, thereby reducing the performance of concrete ...
