Embodiment 1

[0042] refer to Figure 1-7 , a mixing device for the preparation of a compound passivator for heavy metal polluted soil, comprising a mixing box 2 with an opening at the top, the top of the mixing box 2 is fixedly connected with a cover plate 5, and a feed circular pipe is embedded on the left side of the top of the cover plate 5 , both sides of the bottom of the mixing box 2 are fixedly connected with supports, the bottoms of the two supports are fixedly connected with the same U-shaped base 1, the top left side of the U-shaped base 1 is fixedly connected with the battery 3, the U-shaped base 1 The right side of the top is fixedly connected with a tractor connecting seat, and the four corners of the bottom of the U-shaped base 1 are rotatably equipped with traveling wheels. The tractor connecting seat, U-shaped base 1 and traveling wheels are used to facilitate the movement of the mixing device driven by an external tractor. The inner wall of the bottom of the mixing box 2 i...

Embodiment 2

[0055] refer to Figure 8-9 , the present embodiment is based on the first embodiment, and its difference from the first embodiment is that: the rectangular discharge pipe 4 is also provided with a dialing mechanism, and the dialing mechanism includes a rotating device mounted on the rear side of the rectangular discharge pipe 4. The rotating shaft 41 on the inner wall, and the inner wall on both sides of the rectangular discharge pipe 4 are in movable contact with a material-discharging circular tube 38, and the outer side of the material-discharging circular tube 38 is ring-shaped and equidistantly provided with multiple front and rear sides that are all openings. The top inner wall and the bottom inner wall of the round tube 38 are fixedly connected with support rods 40, and the two ends of the two support rods 40 are fixedly connected to the top and bottom of the rotating shaft 41 respectively. The rectangular discharge pipe The front side of 4 is fixedly installed with th...

Abstract

The invention provides a mixing device for preparing a composite passivator applied to heavy-metal-contaminated soil and a using method thereof. The invention aims to solve the problem that an existing mixing device is inconvenient to carry out bidirectional rotary stirring, continuous uniform crushing and movable uniform shifting on raw materials. According to a scheme in the invention, the mixing device comprises a mixing box with an opening in the top, wherein a cover plate is fixedly connected to the top of the mixing box, a circular feeding pipe is embedded in the left side of the top of the cover plate, supports are fixedly connected to the two sides of the bottom of the mixing box, and the same U-shaped base is fixedly connected to the bottoms of the two supports. According to the invention, blanking is convenient, continuous and uniform crushing and bidirectional rotation stirring of raw materials are conveniently realized via a single drive, entered raw materials can be continuously and uniformly screened and crushed, and the raw materials can be synchronously and bidirectionally stirred and turned over, so the mixing efficiency and uniformity are improved; and a mixed passivating agent can be conveniently moved and uniformly stirred so as to meet use requirements.

Description

technical field [0001] The invention relates to the technical field of mixing equipment, in particular to a mixing device for preparing a composite passivator for heavy metal polluted soil and a method for using it. Background technique [0002] For soil, especially the soil polluted by heavy metals, it can no longer be used as a soil substrate for crop growth. The main reason is that crops absorb heavy metal ions in the soil. After humans and animals eat crops, the content of heavy metal ions in the body will increase significantly, which will affect human health. , Therefore, spread compound passivation agent in soil, impel heavy metal ion and passivation agent to react, form the material form that plant is difficult to absorb, and then reach the purpose of purifying soil; In existing compound passivation agent, zeolite, activated carbon and powder The content range of each component of coal ash is 3:1:1 (mass ratio). The effect is that zeolite is a porous aluminosilicate ...
