An automatic water supply system applied to concrete mixing station

Abstract

The invention provides an automatic water supply system applied to a concrete mixing plant, the water storage system includes a pool, a water pump, and a water storage tank, and a liquid level sensor is arranged in the water storage tank; a metering system includes a weighing sensor and a metering water tank; The system includes a booster pump and a nozzle. The inlet of the booster pump is connected to the outlet of the metering water tank through the first sewer pipeline, the inlet of the booster pump is also connected to the outlet of the water storage tank through the second sewer pipeline, and the outlet of the booster pump is connected through The total sewer pipeline is connected to the nozzle; the nozzle is set above the mixing drum, and the connection between the nozzle and the mixing drum is provided with a buffer device; the controller is connected to the water pump, liquid level sensor, weighing sensor, booster pump and nozzle respectively. During the production process, the centralized cleaning of the side wall of the mixing drum is realized by rotating the nozzle, so as to reduce the aggregate adhering to the side wall of the mixing drum. The supply of production water and cleaning water can be realized through one system, with simple structure and convenient operation.

Description

technical field [0001] The invention relates to the field of concrete production equipment, in particular to an automatic water supply system applied to a concrete mixing station. Background technique [0002] With the development of the economy and the continuous progress of technology, the construction engineering industry has also entered a peak period. In the fields of high-speed railway construction, high-rise buildings, underground and underwater projects, people have higher and higher requirements for the quality of concrete production. Concrete mixing plant is a large-scale ready-mixed concrete equipment. Basically, all kinds of construction projects are inseparable from it. The function of concrete mixing plant is usually to add sand, cement, additives, Admixtures and other materials are mixed into homogeneous concrete. The water supply system is an important component system of the concrete mixing plant and plays an important role in the production of the entire m...

Problems solved by technology

[0005] Chinese invention patent (201320547001.9: Concrete mixing station waterway system) discloses a concrete mixing station waterway system. By improving the design of the water metering device, reducing the pipeline pump and adding a waiting water bucket, the concrete mixing station is improved. Water metering accuracy and production efficiency, but because it uses the normal pressure water discharge method, the water discharge time is longer, and because the water curtain cannot be formed, the pollution in the mixer cover is relatively serious, the water outlet is easy to block, and the water discharge pressure is small and cannot be used for mixing. Effective flushing of the shaft increases the chance of shaft holding problems
