Soil beating mechanism and soil remediation system

[0021] Example 1

[0022] See Figure 1~3 In the embodiment of the present invention, a soil beating mechanism includes a beating barrel 1, a motor reducer 2, a beating blade 6, an isolation barrel 7 and a drain pipe 9. The beating barrel 1 is fixed with a coaxial isolation barrel. 7. The isolation cylinder 7 is equivalent to a layer of isolation net to prevent soil blocks, stones, etc. from entering the isolation cylinder 7. The outer wall of the isolation cylinder 7 and the inner wall of the beating barrel 1 form a beating area 8 for storing the soil mixture. The motor reducer 2 is installed on the beating barrel 1 through the motor mounting bracket 3. A beating shaft 5 is provided in the isolation barrel 7. The beating shaft 5 is driven to rotate by the motor reducer 2, and the end of the beating shaft 5 is passed through the flange 4 and bolts Connected to the output end of the motor reducer 2, a beating blade 6 is fixed on the beating shaft 5 to drive the soil mixture to form a vortex. In practical applications, the soil will be partially dissolved in the water to form a slurry, and after the slurry forms a vortex, Undissolved soil masses gradually deposit on the bottom due to their larger specific gravity, and during this process, the internal particles of the mud collide with the soil mass during the movement process, which can further promote the dissolution of the soil mass and make the heavy metal ions inside. Pollutants can enter the water, which is convenient for later centralized treatment. In addition, the design of the isolation cylinder 7 can prevent hard substances such as stones in the water from entering the isolation cylinder 7, and will not cause damage to the beating blade 6. Of course, the beating The barrel 1 is provided with a liquid inlet pipe 10 and a soil feeding port 13 for feeding water and soil into the beating area 8.

[0023] In order to facilitate the output of muddy water or slurry containing heavy metal ions and other pollutants, a drain pipe 9 is connected to the beating barrel 1. As a preference, the drain pipe 9 is connected in the tangential direction of the beating barrel 1 to prevent it It will have a greater impact on the rotation of the mud. In addition, the connection between the drain pipe 9 and the beating bucket 1 should be as upward as possible to avoid insoluble substances from blocking the drain pipe 9, and the nozzle of the drain pipe 9 is installed with metal Filter 17.

[0024] Furthermore, in order to accelerate the dissolution of the soil or the mixing with water to form a slurry, in this embodiment, a plurality of ultrasonic vibrators 11 are installed on the outside of the beating bucket 1, and the ultrasonic vibrators 11 are connected to the ultrasonic generator through a signal line 12. Through the action of ultrasonic, it can accelerate the formation process of mud, and has a better promotion effect on beating.

[0025] Furthermore, the liquid inlet pipe 10 is connected to the water inlet pipe 15 and the gas filling pipe 16, wherein the gas filling pipe 16 is connected to the output end of the air compressor, and is used to fill the water with gas so as to enter the beating area 8 Water forms a gas-liquid mixture, and the shock wave formed by the continuous accumulation of bubbles inside the water can effectively prevent the sedimentation of soil particles.

[0026] In order to facilitate the disassembly of the beating barrel 1 to clean up the substances deposited on the bottom of the beating area 8, the beating barrel 1 is designed to be composed of a top cover 101 and a barrel body 102 in this embodiment, and the top cover 101 and the barrel body 102 pass through Bolt or buckle connection, of course, the above-mentioned liquid inlet pipe 10 and soil feeding port 13 are designed on the top cover 101, and the bottom of the barrel 102 is provided with a vent pipe 14 for emptying the water in the barrel 102 .

[0027] Example 2

[0028] In an embodiment of the present invention, a soil remediation system includes the soil beating mechanism as described in the above embodiment, which can efficiently beat the soil so that pollutants such as heavy metal ions in the soil can remain in the water, and then After the water is settled, flocculated and other operations, the soil can be efficiently repaired.

[0029] It should be noted that in this technical solution, by making the mud vortex, the particles inside the mud collide with the soil block during the movement of the mud, which can further promote the dissolution of the soil block. At the same time, it is formed by the continuous accumulation of ultrasonic waves and bubbles. The shock wave can make pollutants such as heavy metal ions in the soil enter the water, facilitating subsequent centralized treatment; in addition, the design of the isolation cylinder 7 can prevent hard substances such as stones in the water from entering the isolation cylinder 7, and will not cause beating blades 6 Damaged situation.
