The application provides a carnallite acquisition method, which comprises the following steps:
step S1, dividing the salt pan into at least two adjacent carnallite pools, namely a first carnallite pool 1 and a second carnallite pool 2, wherein the first carnallite pool 1 and the second carnallite pool 2 are separated by a dam 4.
Step S2, the water recovery vessel 3 collects carnallite in the first carnallite pool 1, after the collection is completed, the water recovery vessel 3 moves to a first position 11 in the first carnallite pool 1, and the first position 11 is close to the second carnallite pool 2.
The water mining ship 3 is a large-scale mining device for a salt pan, and is used for collecting ore pulp in the salt pan and transporting the ore pulp through an ore pulp pipeline in a carnallite pool; after the carnallite in the first carnallite pool 1 is collected by the water mining ship 3, the water mining ship 3 moves to the second carnallite pool 2 for mining, and the moving process is called ship passing. In this embodiment, the structure of the water cutting vessel 3 is square, and the attached facilities such as a cutting head are mounted on the hull of the square structure. Of course, the structure of the water production vessel 3 may also be of other shapes.
Specifically, the water recovery vessel 3 moves according to a certain track, carnallite is collected in the first carnallite pool 1, and the moving end point of the water recovery vessel 3 is arranged at a first position 11 in the first carnallite pool 1; the water recovery vessel 3 may move according to the distribution of carnallite in the first carnallite 1, or may freely move.
The first position 11 is close to the second carnallite pool 2 and is arranged around the tiled part of the dam 4, and the first position 11 can be the same position or different positions at different periods.
Step S3, a second position 21 is provided in the second carnallite pool 2 corresponding to the first position 11, and the flat part 41 of the dam 4 between the first position 11 and the second position 21 is the ship passing position of the water production ship 3.
The flat laying part 41 comprises a first inclined plane 411 connected with the first carnallite pool 1, a second inclined plane 412 connected with the second carnallite pool 2 and a plane 413 connecting the first inclined plane 411 and the second inclined plane 412, and the included angle between the first inclined plane 411 and the horizontal plane is 15-35 degrees. The included angle between the first inclined surface 411 and the horizontal plane is small, and even if the shape of the water production ship 3 is square, the traction mechanism can move the water production ship 3, so that labor is saved.
The angle between the second inclined plane 412 and the horizontal plane is also 15-35 degrees.
Step S4, laying the rolling elements 5 at the tiled parts 41 of the dam 4, moving the water recovery vessel 3 located at the first position 11 to a second position 21 in the second carnallite pool 2 along the surface of the rolling elements 5 through a traction mechanism, and collecting carnallite in the second carnallite pool 2.
Specifically, the step S4 includes:
laying rolling elements 5 on the flat laying part 41 of the dam body 4;
moving the water production vessel 3 located at the first position 11 along the surface of the rolling bodies 5 to the lay-flat 41 by means of a traction mechanism;
the towing mechanism pushes the water production vessel 3 from the tile 41 into the second location 21 in the second carnallite pool 2.
The rolling bodies 5 are a plurality of airbag bags arranged in parallel. Specifically, the air bag is inflated to be cylindrical, so that the dam body 4 and the hull of the water production ship 3 are protected, a rolling friction condition is formed, and the rolling body 5 rolls when the water production ship 3 moves on the rolling body 5.
Rolling friction refers to the resistance to rolling caused by the deformation of two objects when the two objects are pressed at the contact part when one object rolls on the surface of the other object without sliding or tends to roll, so that the resistance is smaller, and the moving object is more labor-saving and convenient.
The airbag can be laid in contact with each other or at a certain distance when the flat laying part 41 is laid, and the water extraction ship 3 can pass through the airbag.
The area of the rolling body 5 is matched with the size of the water production ship 3, namely the size of the rolling body 5 is just enough to ensure that the water production ship 3 can enter and exit, and the workload is effectively reduced.
The traction mechanism is positioned on the dam body 4, so that the traction mechanism can provide traction force to drag the hydraulic mining ship 3.
The traction mechanism is a crane or a loader, so that labor and trouble are saved.
The traction mechanism firstly moves the water production ship 3 from the first inclined plane 411 of the tiled part 41 to the plane 413 of the tiled part 41, and then pushes the water production ship 3 into the second carnallite pool 2 along the second inclined plane 412 of the tiled part 41, so that the labor is saved, and the operation according to the space position can be facilitated.
Further, in step S2, after the water production vessel 3 moves to the first position 1, the first attachment 31 of the water production vessel 3 is detached, the first attachment 31 is lower than or level with the bottom of the water production vessel 3, and the first attachment 31 includes a cutting head of the water production vessel 3.
The cutting head is an attachment part of the water recovery vessel 3 and is generally lower than or level with the bottom of the water recovery vessel 3, and the removal of the cutting head can effectively prevent the part from being damaged in the traction process. Of course, the first attachment 31 may also comprise other parts of the water production vessel 3.
Further, in step S4, after the water production vessel 3 moves to the second position 21, the first attachment 31 is mounted on the water production vessel 3, so that the water production vessel 3 can continue mining work, and the first attachment 31 can be transported to the water production vessel 3 by the traction mechanism, or can be directly placed on the water production vessel 3 after being detached.
Further, in step S2, after the water production vessel 3 moves to the first position 11, a second attachment connected to the water production vessel 3 is detached, where the second attachment includes a pulp line connector disposed in the first carnallite pool 1.
The pulp line interface is present in each carnallite pool, and is detached before the water recovery vessel 3 is moved, so as not to affect the movement of the water recovery vessel 3.
The carnallite collecting method provided by the invention is concentrated near the ship passing position, rolling friction conditions are provided through the rolling bodies, and the water production ship is moved through the traction mechanism, so that a large amount of preliminary preparation work is not needed, large-area precipitation and water injection procedures are not needed, the ship passing time is short, the method is simple, the production cost is saved, the production efficiency is greatly improved, and the normal production is ensured.
The invention also provides a carnallite collection system, which comprises a first carnallite pool 1, a second carnallite pool 2 adjacent to the first carnallite pool 1, a water recovery ship 3, a dam body 4, a rolling body 5 arranged on the dam body 4 and a traction mechanism arranged on the dam body 4, wherein the first carnallite pool 1 and the second carnallite pool 2 are separated by the dam body 4; the water production ship 3 moves from the first carnallite pool 1 to the second carnallite pool 2 along the surface of the rolling body 5 under the action of the traction mechanism.
