Abstract

The invention discloses a seal-type vacuum heat-insulation concrete mixing drum which comprises a mixing drum shell with an opening, a temperature preservation layer and a heat-insulation layer shell, wherein the temperature preservation layer covers the outer surface of the mixing drum shell; the temperature preservation layer shell is formed through spraying engineering materials on the outer part of the temperature preservation layer; the inner surface of the mixing drum shell is provided with a spiral-shaped blade; the opening part is provided with an air-tight door; the predetermined part of the air-tight door is provided with an air inlet switch; the air-tight door is provided with an air exhaust through hole; and one end of an air exhaust pipe is inserted into the inner cavity of the mixing drum, and one end of the air exhaust pipe is communicated with an air pumping machine. According to the invention, aiming at the problems of the concrete temperature and water-content reduction caused by the dissipation of heat and water content as well as air and carbon dioxide penetration in the transportation process for the existing concrete mixing machine, and difficulty of condensation removing, a seal-type vacuum concrete mixing drum with special efficacy of temperature preservation, heat insulation, noise reduction and the like is provided, the compactness and strength of concrete are increased, and the construction quality is ensured.

Description

technical field [0001] The invention relates to the field of engineering equipment, in particular to a closed vacuum heat-insulating concrete mixing drum. Background technique [0002] Concrete is used more and more because of its abundant raw materials, low price and simple production process. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. The quality of concrete directly affects the construction quality of the project. [0003] Due to the long-term mixing of the existing concrete mixing drum, the air and carbon dioxide in the atmosphere easily penetrate into the interior of the concrete, so the concrete is easy to solidify during transportation. Or when transporting...
