Dry material stirring and conveying device

Abstract

The invention discloses a dry material stirring and conveying device. The device comprises a first material barrel and a spiral material conveying mechanism, wherein the spiral material conveying mechanism is arranged at the bottom of the first material barrel; the spiral material conveying mechanism comprises a second driving motor, a speed reducer and a material conveying pipe, wherein the speedreducer is arranged between the second driving motor and the material conveying pipe, and a material conveying screw is arranged inside the material conveying pipe; a material receiving port is formed in the top of the material conveying pipe, and a second material falling port is formed in the bottom of the material conveying pipe; a first driving motor is arranged at the top of the first material barrel, and a first material falling port is formed in the bottom of the first material barrel; and one side of the first driving motor is provided with a feeding hopper, the end of an output shaftof the first driving motor is connected with stirring rods, and one end of the material conveying pipe is provided with a connecting sealing mechanism. According to the dry material stirring and conveying device, long-distance reliable conveying of concrete can be realized, and the possibility of pipe blockage of a conveying pipeline is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of material conveying equipment, in particular to a dry material stirring and conveying device. Background technique [0002] Concrete is one of the main civil engineering materials in the contemporary era. It is made of cementing materials, aggregates and water in a certain proportion. It is formed by stirring and vibrating, and is cured under certain conditions. Concrete has abundant raw materials and low price , the production process is simple, so its consumption is increasing; at the same time, concrete also has high compressive strength, good durability, and a wide range of strength grades, making it widely used, not only in various civil engineering, Concrete is also an important material in shipbuilding, machinery industry, marine development, geothermal engineering, etc. [0003] After the concrete is mixed and formed, it is transported to the designated location by the concrete pump. In order to ...

Problems solved by technology

In order to shorten the solidification time of concrete so that it can solidify as soon as possible after reaching the construction site, a common practice in the prior art is to add additives such as quick-setting agents during the concrete mixing process, so that the additives and other concrete materials are mixed evenly before the concrete is mixed. For pumping, due to the action characteristics of additives such as accelerators, it will have a great impact on the pumping performance of concrete. The pumping pipeline of concrete should not be too long, otherwise the concrete will be easy to solidify before it is sent out of the pumping pipeline. clogged pumping pipes

Therefore, it is difficult to realize long-distance pumping of concrete in the prior art, which brings troubles to concrete construction and low construction efficiency. In addition, if there is a power failure or other failure during the concrete pumping process, the concrete will stagnate in the pumping pipeline And quickly solidified, it is difficult to clean up, not only affects the construction progress, but also has a large project loss, which is not conducive to saving construction costs
