Description

An in-situ sludge solidification mixer

technical field

The utility model relates to the technical field of hydraulic mixers, in particular to the technical field of improving and treating dredged silt produced in water conservancy and water environment treatment projects.

Background technique

In my country's water conservancy and water environment treatment projects, a large amount of dredging silt is produced every year. It is estimated that in recent years, the annual dredging volume in Jiangsu Province has reached 50 million cubic meters, and the annual dredging volume in the Pearl River Delta region has reached 80 million cubic meters. The amount of dredging required due to serious pollution reached 25.12-34.48 million cubic meters. The treatment of dredged silt is usually based on requisitioned land and piled up. Taking Taihu Lake as an example, if all the sediment is dredged and excavated, it will need to occupy an area of 8.4 to 11.5 square kilometers if it is stacked at a filling height of 3 meters. With the shortage of urban construction and industrial and agricultural land, land acquisition has become a major bottleneck restricting water conservancy and water environment improvement projects.

Aiming at the land occupation problem of silt stacking, the utility model considers that the silt occupying land and polluting the environment can be converted into filling soil that can be used for earthworks such as roads, embankments or foundation filling by solidifying and recycling the silt. It can solve the land occupation problem of silt, and at the same time generate renewable soil resources.

In the construction of solidification treatment of sludge, a sludge solidification treatment machine (such as patent: ZL200420028026.9) is usually used for solidification and mixing construction. car, the processing efficiency per hour is only 100-150 cubic meters of sludge. Moreover, the fixed investment cost of the sludge solidification treatment machine is relatively high, which greatly limits the efficiency of the sludge solidification treatment.

Contents of the invention

The purpose of the utility model is to provide an in-situ sludge solidification mixer with low processing cost, high efficiency, convenient and flexible operation and its working method.

One side near the connection part I is provided with a longitudinal fixing member, and a horizontal connecting pivot pin hole perpendicular to the longitudinal fixing member is arranged on the longitudinal fixing member; the transmission shaft of the hydraulic motor is connected with the hydraulic motor transmission gear, and the hydraulic motor transmission gear is connected with the stirring shaft through the transmission chain. The stirring shaft gear in the middle of the shaft is connected, and several stirring teeth are uniformly arranged on the stirring shaft; a solidified material sprayer is arranged above the stirring tooth, and the material inlet end of the solidified material sprayer is placed on the connecting piece.

Connecting bolts are arranged on the connecting piece of the utility model.

Based on the working method of the above-mentioned in-situ sludge solidification mixer, the method comprises the following steps:

The first step: install the in-situ sludge solidification mixer on the bucket wall of the hydraulic excavator through the connecting pivot pin hole, and connect the oil inlet pipeline and the oil return pipeline with the hydraulic excavator inlet and outlet pipeline valves. Connect the upper end of the curing material sprayer to the curing material delivery hose;

The second step: Spray the solidified material through the solidified material sprayer, drive the hydraulic motor gear through the hydraulic motor, transmit the power to the stirring shaft gear through the transmission chain, and drive the stirring teeth to solidify and stir;

The third step: use the hydraulic excavator to control the rotation speed of the stirring teeth, the stirring depth and the construction direction.

The utility model adopts the above-mentioned technical scheme, and has the following advantages compared with the prior art:

1. It can be installed on an ordinary hydraulic excavator as a mixer, and there is no need to set up a special sludge solidification processor.

2. The utility model can be installed on excavators of different manufacturers and models by adjusting the joint adapter.

3. When the utility model is used for on-site construction, the original control system of the excavator can be used to control the mixing depth and rotating speed of the mixer, and the operation is convenient and flexible.

4. Compared with the sludge solidification processor, the utility model has the advantages of low processing cost and high efficiency, and is suitable for manufacturing multiple sets at the same time for construction in large-area sludge storage yards, which can greatly shorten the construction period.
