Description

Soil material box for soil heavy metal restoration

technical field

The utility model relates to a soil material box for soil heavy metal restoration.

Background technique

At present, when remediating soil containing heavy metals, the contaminated soil containing heavy metals is first sent to the soil material box, and the soil material box is sent to the beating tank through the conveyor belt below, and the contaminated soil is treated according to a certain water-soil ratio in the beating tank. Water injection and beating form mud. The heavy metal on-line monitor provides real-time monitoring data. The mud is transported to the mixing tank through pump pressure, and the required MSC magnetic material is weighed and put into the magnetic material warehouse, stirred to form a mixed mud, and the mixed mud is pumped to enrichment Under stirring, the MSC captures the specified heavy metals. After the mixed mud is pumped from the enrichment tank to the magnetic enrichment recovery machine, it is separated into purified mud and MSC magnetic materials enriched with heavy metals. After the purified mud is tested by the monitor and reaches the standard , and then sent to the bag filter press to realize the separation of mud and water, the water enters the reservoir for recycling, and the purified soil is placed in a clean soil safe area for centralized backfilling. However, when the polluted soil is sent into the soil material box by the excavator, it is necessary to filter out large pieces of soil containing heavy metals to prevent the outlet of the soil material box from being blocked, and the filtered larger soil pieces need to be pulverized by a pulverizer Therefore, processes such as filtering and crushing are required before the contaminated soil containing heavy metals is sent into the soil bin, which not only increases labor and cost, but also reduces work efficiency.

A group of insertion rods with smooth surfaces are equidistantly installed in the feeding area, and a group of insertion rods form a soil block carriage structure. The soil block carriage structure is inclined, and the soil block carriage structure The end part extends into the crushing area of the road, and a group of ribs are connected to the bottom of the soil block carriage structure, and the two ends of the ribs are fixedly connected with the inner wall of the soil material box;

Two crushing rollers and a scraper with an inclined plane structure are installed in the crushing area, an annular groove is opened on each of the crushing rollers, a crushing plate is arranged between the two annular grooves, and the end of the scraper is The parts are fixedly connected with the inner wall and the partition of the soil material box body respectively, and the center of the crushing roller is connected with a rotating shaft, and the rotating shaft passes through the soil material box body and is connected with the motor.

In the earth material box for soil heavy metal restoration, the feed buffer plate is connected to the surface of the partition, and the angle between the feed buffer plate and the horizontal plane is 15 degrees.

The soil material box for soil heavy metal restoration, the outer box wall of the soil material box body is connected with a skirt board, the skirt board is fixedly connected with the support frame, and the bottom of the support frame is fixed with the backing plate connect.

As for the soil material box for soil heavy metal restoration, a conveying system is arranged below the discharge port, and the conveying system is installed on a backing plate.

The beneficial effects achieved by the utility model are:

1. In the utility model, the soil containing heavy metals is directly fed into the feeding box body from the feeding hopper by a forklift. The soil block sliding frame is arranged in the feeding box body, and the soil block sliding frame is composed of a group of smooth-surfaced metal Composed of rods, and the distance between every two adjacent rods is the same, so that a gap is formed between two adjacent rods, and the gap between the soil feeding rods that is fed into the feed box Falling, sent from the discharge port to the conveyor belt of the conveying system, and the soil block that is larger than the gap between the two inserting rods will fall into the crushing area along the soil block carriage, and two crushing rollers are installed in the crushing area The two crushing rollers are provided with annular grooves, and a crushing plate is arranged between the two annular grooves. Therefore, when large pieces of soil fall onto the crushing rollers, the crushing plates on the crushing rollers will pass through the annular grooves. The soil is crushed, and the crushed soil is sent to the discharge port from the opening at the bottom of the partition, and the crushed soil is sent to the belt of the conveying system and sent to the beating tank.

2. The utility model has the characteristics of simple structure and convenient operation. The new model is equipped with a soil block slide frame in the feeding box body, and the bulk soil can be separated through the soil block slide frame to prevent the large block soil from entering the feed box. When the material box is in the box, the outlet is blocked, and when a large piece of soil enters the crushing area, the large piece of soil can be directly crushed. Therefore, the entire operation process only needs to send the polluted soil directly to the crushing area through a forklift. The process of screening and crushing can be completed in the feeding box, and the feeding buffer plate is set in the feeding box to buffer the soil and prevent the soil from falling directly from the discharge port and accumulating on the conveyor belt.
