Problems solved by technology

[0004] 1. The sludge strength in the sludge temporary storage area is extremely low, and the construction equipment is prone to subsidence, making it impossible to directly enter the site for construction
[0005] 2. The temporary sludge storage area was originally covered with high-strength HDPE film. During the construction process, devices such as injection, stirring, and inserting boards will destroy this covering film, and the safety is threatened.
[0006] 3. The reactions between several agents and between agents and sludge do not happen at the same time, but in chronological order, otherwise the treatment effect will not be achieved
[0007] 4. In the process of adding chemicals, the odor will overflow after the cover film is damaged, which may not only endanger the lives of the staff, but also cause pollution to the surrounding environment, which is not allowed in terms of environmental protection
[0008] The implementation of the chemical vacuum preloading method and the dissolved gas-pharmaceutical vacuum preloading method encountered the above four problems in the process of sludge in-situ treatment. If these problems cannot be solved, the chemical vacuum preloading method and the dissolved gas chemical vacuum preloading method it is difficult to implement

Embodiment 1

[0029] In this example, see Figure 1-Figure 3, an intelligent dosing system for sludge in-situ treatment, which also includes a main frame 11, including a walking subsystem, a positioning subsystem, a stirring subsystem, and a dosing subsystem; the walking subsystem includes a main frame 11, a suspension 19, Rubber crawler 1, polyurethane suction cup 2 and travel control system 12, rubber crawler 1 and main frame 11 are connected by suspension 19, and a series of polyurethane suction cups 2 are arranged on the rubber surface of rubber crawler 1 facing away from the track wheel, when walking When the subsystem is walking or the stirring subsystem is in the drilling process, the polyurethane suction cup 2 is tightly sucked to the sludge covering film, or the polyurethane suction cup is tightly sucked to the construction cushion, so that the polyurethane suction cup forms a temporary anti-slip and positioning device; Walking control system 12 is installed on main frame 11, and w...

Embodiment 2

[0041] This embodiment is basically the same as Embodiment 1, especially in that:

[0042] In this embodiment, the intelligent control system controls the dosing subsystem to add at most three different medicines, and by controlling the medicine injection pump 21, the interval and duration of adding different medicines are regulated. The drill pipe 6 and the triple drug injection pipe 9 can consider the interaction between the chemical reactions of the agents, and inject different types of agents according to the sequence of the chemical reactions. Up to three different agents can be added. These agents react quickly in the sludge and Destroy the microstructure of the sludge. If you need to add two or one agent, you don’t need to replace the drill pipe. You can directly use the inner layer and the middle layer to realize the injection of two agents, and only use the inner layer pipe to realize the injection of a single agent.

[0043] In this embodiment, the injection agent gr...

Abstract

The invention discloses an intelligent dosing system for sludge in-situ treatment, wherein the system comprises a walking subsystem, a positioning subsystem, a stirring subsystem and a dosing subsystem and has four functions of remote intelligent control positioning, walking, dosing and stirring. A stirring drill rod and chemical injection pipes are combined into a whole, chemical injection and drilling are achieved at the same time; a crawler belt made of a light rubber material is adopted for advancing, and all operations can be remotely controlled. The stirring device adopts three-shaft stirring by referring to a common stirring pile machine and has drilling and stirring functions, each shaft is provided with three chemical injection pipes, and the chemical injection pipes are connectedwith different chemical grouting pumps respectively. Improvements are made on the basis of existing construction equipment, so construction equipment can directly treat sludge to enter a site, the treatment effect is improved, the life safety of workers is guaranteed, pollution to the surrounding environment is reduced, a chemical vacuum preloading method and a dissolved gas chemical vacuum preloading method can be truly implemented, the intelligent degree is high, implementation and control are easy, and important significance is achieved for environmental protection.

Description

technical field [0001] The invention relates to a mud treatment device, in particular to a chemical addition system for treating sludge in a sludge pit, which is applied in the technical fields of geotechnical engineering and resource and environment protection. Background technique [0002] Engineering waste mud, referred to as "waste mud". As more and more engineering waste mud is produced in the process of engineering construction, the waste mud will cause serious pollution to the place where it is placed. As people's awareness of environmental protection gradually increases, this extensive mud disposal method is constantly being questioned and opposed, and technical personnel in the industry are urgently required to develop efficient and environmentally friendly mud disposal technologies. [0003] The patent document with the patent number ZL201510322445.6 discloses a chemical vacuum preloading method for treating engineering waste mud, and the patent document with the ...
