Integrated intelligent high-pressure injecting liquid medicine automatic dispensing and injecting device

Abstract

The invention discloses an integrated intelligent high-pressure injecting liquid medicine automatic dispensing and injecting device. The integrated intelligent high-pressure injecting liquid medicineautomatic dispensing and injecting device comprises a power supply unit, an intelligent control system, a sieving weighing metering unit, a stirring mixing unit, a storage unit and an injecting unit.According to the set liquid medicine concentration and the volume of the stirring mixing unit, the needed using amount of liquid medicine is calculated through the intelligent control system, the liquid medicine is injected into the stirring mixing unit by sieving and weighing (metering), and a solvent is injected, the liquid medicine is transported to the storage unit after stirring mixing. In repairing, the well-dispensed medicine agent in the storage unit is transported by the injecting unit through a high-pressure liquid pump to a repairing drilling device according to the set pressure andthe flow quantity, and polluted soil and underground water are repaired. Liquid medicine mixing dispensing of the device is automatically conducted through control of the intelligent control system according to the consuming amount of the medicine agent, the residual amount of the medicine agent in the storage unit and the medicine agent dispensing speed. Integrated design is adopted, all the composing units are integrated in a standard container, and transporting and using are convenient.

Description

technical field [0001] The invention relates to the technical field of soil and groundwater remediation, in particular to an integrated intelligent high-pressure injection liquid automatic configuration and injection equipment. Background technique [0002] Groundwater pollution in my country has shown a trend of development from point-like pollution to band-like and surface-like pollution. Because the in-situ injection method does not require excavation, has little disturbance and low cost, it has become a hot spot and direction for the development of groundwater restoration. [0003] High-pressure jetting grouting technology is a construction technique that combines grouting technology and high-pressure water conservancy jetting cutting technology. During solidification stabilization and chemical reduction and oxidation, high-pressure injection equipment is used to inject the agent into the deep soil, so that the agent can be effectively and evenly mixed with the polluted ...

AI Technical Summary

Problems solved by technology

[0004] According to the type of injection pipe, the high-pressure injection method can be divided into single-pipe method, double-pipe method, triple-pipe method, etc. The single-pipe method only sprays the chemical solution, which has the advantages of fast construction speed, low cost, and basically no slurry return point; but the effect The range is too small, which affects the construction efficiency, and the mixing effect is general

The double-pipe method sprays high-pressure slurry and compressed air, and the radius of action is significantly larger than that of the single-pipe method, and the mixing effect is also greatly improved when the compressed air is assisted in cutting, but part of the slurry returns during the construction process.

In the triple pipe injection method, low-pressure slurry displacement, ultra-high-pressure water and compressed air cutting are used. Yes, the effective radius of this method is significantly increased, and the mixing effect is the best, but its principle is that the mud pump injects lower pressure. Filling and replacing the grout will increase the construction period and cost to a certain extent, and the use of a large amount of high-pressure water will greatly reduce the strength of the foundation in the construction area, affecting the progress of subsequent projects

[0005] Due to the different process principles of different soil and groundwater remediation technologies, the remediation equipment required will also be different. The soil and groundwater remediation equipment currently on the market is basically a special equipment specially designed for a certain remediation technology, and the function is relatively simple.

The in-situ restoration of soil and groundwater uses drilling equipment to drill into the target area and then starts high-pressure injection of repair liquid. During the repair process, the process of adding and injecting liquid medicine is rough, and the pressure control is difficult, which cannot meet the needs of groundwater pollution control; currently there is no drug collection in China. Intelligent equipment that integrates liquid configuration and injection. The integrated intelligent high-pressure injection liquid automatic configuration and injection equipment involved in the present invention ensures the efficient mixing and precise delivery of medicines in the high-pressure jet repair process, improves injection accuracy, and reduces repair costs. cost, solved the technical problem of precise restoration, and provided strong technical and equipment support for soil and groundwater pollution control
