Description

Technical Field

[0001] The invention relates to the technical field of waste mud and slag, in particular to construction equipment used for forming liquid solidified soil from waste mud and slag. Background Art

[0002] With the continuous advancement of urbanization and the large-scale development of various infrastructure construction, a large amount of waste mud and slag is generated in engineering construction. These waste mud and slag usually contain a lot of water and soil particles. If they are not properly handled, they will not only occupy a lot of land resources, but also easily cause serious pollution to the environment.

[0003] At present, the main way to deal with waste mud and slag is to evaporate its moisture by drying it in the sun, so as to facilitate subsequent transportation and disposal. However, this treatment method has serious technical problems. On the one hand, the drying of waste mud and slag requires a large area of ​​site. With the increasingly tight land resources, it is difficult to find a suitable drying site. On the other hand, the drying process is greatly affected by weather conditions. If it encounters rainy weather, the drying time will be greatly extended. Moreover, the drying method is time-consuming and inefficient, and cannot meet the needs of quickly processing large amounts of waste mud and slag. In addition, long-term drying can easily lead to the spread of harmful substances in the mud and slag, posing a potential threat to the surrounding environment and human health.

[0004] In summary, the existing methods of treating waste mud and slag have many drawbacks in the drying process, which is difficult to meet the actual engineering needs. There is an urgent need for a construction equipment that can efficiently and quickly convert waste mud and slag into a form that is easy to handle and utilize. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides construction equipment for forming waste mud and slag into liquid solidified soil, thereby solving the problems that the existing waste mud and slag treatment adopts the air-drying method, which requires a large area of ​​site, is greatly affected by the weather, is time-consuming and inefficient, and easily leads to the spread of harmful substances.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: Construction equipment for forming liquid solidified soil from waste mud and slag, including a separation component for separating substances in the waste mud and slag according to particle size;

[0007] The crushing and recycling component is installed on the outside of the separation component, and is used to crush the larger-sized slag separated by the separation component and recycle and separate it again;

[0009] A mixing component is installed at the outlet of the separation component and the feeding component, and is used to mix the separated slag and the curing agent;

[0010] The water spraying assembly is used to spray clean water into the interior of the separation assembly.

[0011] Preferably, the separation component includes a shell, a driving wheel is installed on the outside of the shell, a rolling screen is rotatably connected to the inside of the shell through the driving wheel, and a discharge pipe is fixedly connected to the bottom of the shell for discharging the separated waste soil.

[0012] Preferably, the crushing and recovery assembly includes an outer shell and a recovery structure, the outer shell is installed at the outlet end of the rolling screen, two crushing rollers are rotatably connected inside the outer shell, gears are fixedly connected to the outer sides of the two crushing rollers, the two gears are meshed with each other, and a motor is fixedly connected to the outer side of the outer shell, one of the crushing rollers is fixedly connected to the output end of the motor.

[0013] Preferably, the recovery structure includes a collecting hopper, which is installed at the bottom of the outer shell and connected to the inside of the outer shell. A Jiaolong conveyor is also installed on the outside of the shell. The input end of the Jiaolong conveyor is connected to the collecting hopper, and the output end of the Jiaolong conveyor is fixedly connected to a discharge pipe.

[0014] Preferably, the feeding assembly comprises a storage bin, which is installed on the outside of the shell, and a quantitative tube is fixedly connected to the bottom output end of the storage bin.

[0015] Preferably, the mixing assembly includes a double-screw mixer, which is located at the output end of the discharge pipe and the bottom of the output end of the metering pipe. A discharge hopper is installed on the outside of the double-screw mixer. The double-screw mixer is used to mix the curing agent and the slag, and the mixed slag is discharged from the discharge hopper.

[0016] Preferably, the water spray assembly includes a filter, the filter is fixedly connected to the bottom of the shell, a water pump is fixedly connected to the outside of the filter, the input end of the water pump is connected to the filter, the output end of the filter is connected to a connecting pipe, the other end of the connecting pipe is equipped with a nozzle, the nozzle is installed on the top of the shell and is connected to the inside of the shell.

[0017] Preferably, a feed hopper is fixedly connected to the outside of the discharge pipe, and the output end of the feed hopper is located at the input end of the rolling screen.

[0020] Working principle: The waste mud and slag to be processed is poured from the feed hopper into the shell for screening. The waste mud and slag will enter the rolling screen, and then the rolling screen will be driven by the driving wheel to rotate as a whole, and then screened through the mesh holes on the outer wall of the rolling screen. The smaller slag will fall between the shell and the rolling screen, and then be discharged through the discharge pipe, and then fall into the double-screw mixer. Then the curing agent stored in the storage bin is synchronously transported to the double-screw mixer, and the curing agent and slag are mixed by the double-screw mixer. The mixed solidified soil is discharged from the discharge hopper, thereby completing the treatment of the entire waste mud and slag. During the screening process of the rolling screen, the larger debris moves along the arrangement direction of the rolling screen, and then falls into the outer shell. The driving motor drives the crushing roller to rotate, and then the two gears cooperate to make the crushing roller rotate in the opposite direction. In this way, the fallen debris can be crushed to reduce the particle size of the debris. The crushed debris falls into the collecting hopper and is then transported to the feed hopper again through the Jiaolong conveyor. In this way, the debris is screened for the second time, which can reduce the stock of large-particle debris and greatly improve the processing effect.

[0021] When the shell and the rolling screen are screening the debris, water will be sprayed into the shell through the nozzle, so as to facilitate the separation of the waste mud and debris. At the same time, the separated waste water flows into the filter for filtration, and then the filtered water is pumped out by the water pump and transported to the inside of the nozzle through the connecting pipe, so as to realize the recycling of waste water and reduce waste.

[0022] The present invention provides a construction device for converting waste mud and slag into liquid solidified soil. It has the following beneficial effects:

[0023] 1.
