Problems solved by technology

[0003] Among them, the patent application number 201620985385.6 proposes a water tank, a weighing device, a water adding system and a concrete mixing equipment. It is also provided with a waste water tank in the water supply weighing device for concrete production, so that the waste water can be recycled, but It also has many problems and deficiencies: For example, when pumping clean water in the water supply tank, due to the large flow rate of the booster pump, the water inlet speed is too fast, and the pumping has inertia, so the accuracy of water supply weighing is not high; The water outlet of the water inlet pipe is set on the upper part of the water tank and the pumping water pressure is relatively high, so the water outlet of the water inlet pipe of the clean water chamber has a greater impact on the water tank, which further causes inaccurate water supply weighing. Similarly, the installation method of the water inlet pipe of the sewage chamber is also It will cause inaccurate weighing of water supply; the water tank is suspended on the bracket, and it may shake when supplying water to its interior, resulting in inaccurate weighing; when the water to be weighed is greater than the target value or the moisture content of the aggregate is high, it is necessary When carrying out the deduction of the water scale, because the flow rate of each outlet pipe is relatively large, it is impossible to accurately deduction the scale

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0021] Such as figure 1 As shown, the environment-friendly concrete mixing building of the present invention includes a material storage system, a material conveying system, an aggregate weighing device, a powder weighing device, a high-precision water supply weighing device, a liquid admixture weighing device, and a concrete mixing host The high-precision water supply weighing device includes a water tank 1, and the water tank 1 includes a clean water chamber 2 and a recovery waste water chamber 3, and the clean water chamber 2 and the recovery waste water chamber 3 are separated by a partition 13, and the partition There is a gap between the upper end of 13 and the top wall of the water tank, and the gap forms a connecting channel connecting the clean water chamber 2 and the recycled waste water chamber 3...

Abstract

The invention discloses an environment-friendly type concrete mixing plant which can recycle wastewater generated in production as mixing water for producing concrete. A precise weighing water inlet tube is arranged in a high-precision water supply weighing device, so that water can be supplied to a water tank through the precise weighing water inlet tube at the tail stage of water supply weighing; a coarse weighing water inlet tube extends into the bottom of the water tank, a buffer hole plate is arranged at a water outlet of the coarse weighing water inlet tube; the water outlet of the precise weighing water inlet tube is horizontally formed, so that impact, on the water tank, of inlet water can be reduced; and two weighing sensors, a guide column and a guide sleeve are arranged on a beam, so that water tank swing and shake further can be reduced; and a buckled-weighing leakage tube is further arranged, so that precise buckled-weighing is realized. The environment-friendly type concrete mixing plant can improve water supply precision, and improves concrete quality.

Description

technical field [0001] The invention relates to an environment-friendly concrete mixing building, in particular to an environment-friendly concrete mixing building capable of saving water resources, in particular to a high-precision water supply weighing device therein. Background technique [0002] The concrete mixing plant is the main equipment for the production of commercial concrete, and has developed rapidly in recent years. In the process of concrete mixing plant production, in order to clean concrete mixers, concrete mixing tank trucks and other equipment, a large amount of water resources are needed. If the cleaned waste water and waste residues are discharged directly, the surrounding environment will be polluted. Therefore, more and more More and more commercial concrete manufacturers have researched many solutions for recycling waste water and waste residue. Firstly, the waste water waste residue is separated from sand and gravel, and the concentration is adjuste...
