Small concrete mixing plant and concrete mixing method

Abstract

The invention provides a small concrete mixing plant and a concrete mixing method. The small concrete mixing plant comprises a storage bin, a separating belt, a flat belt, a mixing barrel, a rotary body, a mixing arm and a blade, wherein a water outlet device is arranged on the mixing barrel and comprises a water outlet hole and a thick water pipe and a thin water pipe which are communicated with the water outlet hole, the thick water pipe and the thin water pipe are respectively arranged at two sides of the mixing barrel and are jointly connected with a centrifugal water pump, the diameter of the thin water pipe is one half of the thick water pipe. The concrete mixing method comprises the steps of connecting the thin water pipe, adjusting a gap between the separating belt and the flat belt, and designing the water injection time to be one half of the original water injection time. According to the invention, water outlet time can be shortened, water pressure can be increased, concrete coagulation can be reduced, concrete mixing level can be improved, and accidental factor risk and waste can be reduced.

Description

technical field [0001] The invention relates to the technical field of concrete mixing plant production, in particular to an improved small concrete mixing plant and a concrete mixing method. Background technique [0002] At present, concrete mixers are mostly used in the field of construction, mainly for mixing and storing concrete. During the working process of the concrete mixer, a large amount of water needs to be added to the mixer to facilitate mixing with cement. [0003] In the current mixer, the manufacturer generally designs the water outlet device to discharge water from one side, connect the water pump or the water tank through the water pipe, and guide the water into the mixer. The problem we are currently facing is that the diameter of the water pipe used is too large, the water outlet time is too long, the water pressure is too small, the cement mortar is easy to condense on the mixing arm and scraper, resulting in uneven mixing of concrete, affecting the qua...

AI Technical Summary

Problems solved by technology

The current problem is that the diameter of the water pipe used is too large, the water outlet time is too long, the water pressure is too small, the cement mortar is easy to condense on the mixing arm and scraper, resulting in uneven mixing of concrete, affecting the quality of concrete, and cleaning and maintenance of the mixer Personnel bring considerable labor intensity

[0004] At the same time, at present, most of the domestic mixing plants adopt the microcomputer automatic control method, which is less restricted by human factors and more limited by mechanical equipment factors. Because the mixing process is often accompanied by uncertain factors, there are often phenomena such as aggregate overflow and mixer blockage. It not only causes a lot of waste of labor and materials, but also makes it difficult to maintain continuous and uninterrupted production, which makes the production efficiency of the mixing plant at a low level for a long time
