[0023] The present application provides a switching device 100 (hereinafter referred to as the switching device 100), which includes a slot body 10 of a strip structure, wherein the slot body 10 is formed with a first accommodating chamber 11 for accommodating a first slurry and a second accommodating chamber 12 for accommodating a second slurry, wherein the second accommodating chamber 12 includes a first chamber 121 and a second chamber 122 that are connected, wherein the first accommodating chamber 11 and the first chamber 121 are arranged at one end of the length direction of the slot body 10, and are distributed in upper and lower layers. The second chamber 122 is arranged at the other end of the length direction of the slot body 10, and a valve portion 20 is arranged on the side wall of the first accommodating chamber 11, wherein the valve portion 20 can be opened or closed, wherein the valve portion 20 is in an open state, wherein the first accommodating chamber 11 is connected to the second accommodating chamber 12, and wherein the valve portion 20 is in a closed state, wherein the first accommodating chamber 11 is separated from the second accommodating chamber 12. For example, a partition can be arranged in the slot body 10, and the first accommodating chamber 11 and the second accommodating chamber 12 can be separated by the partition. The partition can be a stainless steel plate with a thickness of 10 mm, but is not limited thereto. The tank body 10 is further provided with a first pulp discharge port 110 communicating with the first accommodating chamber 11, and a second pulp discharge port 120 communicating with the second accommodating chamber 12. The first pulp discharge port 110 may be a circular hole with a hole diameter greater than 200 mm. The second pulp discharge port 120 may be a circular hole with a hole diameter greater than 200 mm.

[0024] According to the above description, the first accommodating chamber 11 is used for the first slurry, and can be directly discharged to the concentrate pool through the first slurry discharge port 110, and the second accommodating chamber 12 is used to accommodate the second slurry, and can be discharged to the slurry concentration equipment through the second slurry discharge port 120. During the slurry transportation process, when it is detected that the slurry grade in the first accommodating chamber 11 is higher than the preset value, such as 18%, the first slurry discharge port 110 can be opened to allow the slurry in the first accommodating chamber 11 to be directly discharged from the first slurry discharge port 110 and enter the concentrate pool, thereby avoiding the need for concentrating again through the concentration equipment. If the slurry grade in the first accommodating chamber 11 is normal, the valve part 20 is opened to allow the slurry in the first accommodating chamber 11 to directly enter the second accommodating chamber 12 and be discharged to the concentration system through the second slurry discharge port 120, thereby making it convenient and quick to switch the flotation process, shorten the flotation process, and improve the metal recovery rate.

[0025] In one embodiment, the switching device 100 further includes a first pipe 25 and a second pipe 30, wherein the first pipe 25 is in communication with the first pulp discharge port 110, and the second pipe 30 is in communication with the second pulp discharge port 120. The first pipe 25 can allow the pulp to flow directly into the concentrate pool, and the second pipe 30 can allow the pulp to flow to the concentrate flotation equipment, so as to facilitate the switching device 100 to be connected to the pulp concentration system.

[0026] In one embodiment, the first pulp discharge port 110 and the second pulp discharge port 120 are arranged on the same side of the tank body 10 and are distributed up and down, and the first pipe 25 and the second pipe 30 extend in parallel. In this way, the first pulp discharge port 110 and the second pulp discharge port 120 are located on the same side, which facilitates the first pulp discharge port 110 and the second pulp discharge port 120 to be connected to the first pipe 25 and the second pipe 30 respectively. In addition, the first pipe 25 and the second pipe 30 extend in parallel, which is also conducive to the effective use of the outer space of the tank body 10.

[0027] Please refer to Figure 3 and Figure 4 , Figure 3 for Figure 1 FIG. 1 is a top view of a partial structure of the switching device 100 shown in FIG. 1 , wherein the valve portion 20 is in an open state. Figure 4 Schematic diagram of the cover plate 22.

[0028] In one embodiment, the valve portion 20 includes a through hole 21 provided on the bottom wall of the first accommodating chamber 11 and a cover plate 22 movably provided at the through hole 21, when the cover plate 22 is opened, the valve portion 20 is in an open state, and when the cover plate 22 covers the through hole 21, the valve portion 20 is in a closed state. The valve portion 20 has a simple structure and is easy to implement. Optionally, the cover plate 22 can be rotatably connected to the through hole 21 of the trough body 10, but is not limited thereto. In this embodiment, the cover plate 22 is detachably connected to the through hole 21 of the trough body 10, that is, the cover plate 22 can be removed from the trough body 10 and taken out from the first accommodating chamber 11.

[0029] In one embodiment, in order to facilitate the removal of the cover plate 22, a handle 23 is further provided on the cover plate 22, and the handle 23 protrudes from the surface of the cover plate 22. The handle 23 is convenient for a person to grasp, thereby facilitating the disassembly and assembly of the cover plate 22. For example, in order to prevent leakage, a sealing ring may be provided, and the sealing ring may be provided around the through hole 21 to achieve axial sealing; the sealing ring may also be sleeved on the outer side of the cover plate 22 to achieve radial sealing.

[0030] exist Figure 3 and Figure 4 In the embodiment shown, the through hole 21 is set as a circular stepped hole, and the cover plate 22 is set as a circular cover plate, which is supported on the stepped surface of the circular stepped hole. The circular stepped through hole and the circular cover plate are easy to install, and there is no need to adjust the installation position and installation angle. The aperture of the large end of the through hole 21 can be set to 230 mm, and the aperture of the small end of the through hole 21 can be set to 220 mm. The diameter of the circular cover plate can be set to 225 mm.

[0031] In one embodiment, Figure 3 and Figure 5As shown, the switching device 100 further includes a baffle 40 accommodated in the first accommodating chamber 11, and the baffle 40 is used to block the first pulp discharge port 110 when the valve portion 20 is opened. In this way, the baffle 40 blocks the first pulp discharge port 110 to prevent the slurry from flowing out of the first pulp discharge port 110. The specific structure of the baffle 40 is not limited. Figure 3 In the illustrated embodiment, the baffle 40 is square, and a handle 41 is provided on the baffle 40 to facilitate taking the baffle 40. The baffle 40 can be a 300*300 square metal baffle.

[0032] In one embodiment, Figure 4 As shown, the tank body 10 also includes a first fixing plate 13 and a second fixing plate 14 disposed on both sides of the first pulp discharge port 110, a first gap 130 is reserved between the first fixing plate 13 and the side wall where the first pulp discharge port 110 is located, and a second gap 140 is reserved between the second fixing plate 14 and the side wall where the first pulp discharge port 110 is located, and the baffle 40 is inserted into the first gap 130 and the second gap 140 to block the first pulp discharge port 110. In this way, the baffle 40 can be fixed by the first fixing plate 13 and the second fixing plate 14 to ensure the stability of the position of the baffle 40. The first fixing plate 13 and the second fixing plate 14 are strip-shaped plates, and the width can be set to 10 mm.

[0033] In one embodiment, the volume of the first accommodating chamber 11 is smaller than the volume of the second accommodating chamber 12. In one embodiment, the bottom wall of the first accommodating chamber 11 is inclined toward the location of the first slurry discharge port 110, and the bottom wall of the second accommodating chamber 12 is inclined toward the location of the second slurry discharge port 120. This facilitates the outflow of slurry.

[0034] The switching device 100 provided in the present application can block the through hole 21 with the cover plate 22 when the foam grade in the first accommodating chamber 11 is high (above 18%), the roughing overflow occurs, or the copper grade of the tailings is high, so that the slurry can directly enter the concentrate pool from the first slurry discharge port 110, shorten the flotation process of the slurry, and achieve "early collection" for useful minerals. When the tailings grade is normal, the grade in the first accommodating chamber 11 is not high, or the concentrate grade is low, the first slurry discharge port 110 is blocked with a baffle 40, and the cover plate 22 is removed, so that the rough ore in the first accommodating chamber 11 enters the second chamber 121 through the through hole 21, and merges with other roughing foam tanks through the pipeline to enter the concentration process operation. The two modes can be quickly switched according to the changes in the properties of the original ore and the process needs, without stopping, which is efficient and simple.

[0035] In addition, compared with the traditional flotation process, the switching device 100 provided by the present application can quickly and flexibly switch the roughing process, and does not require too much manpower, and can be quickly operated by a single person, which is more practical, safe, efficient and convenient than the traditional flotation process. When the properties of the original ore change, the use of the switching device 100 can quickly reduce tailings, improve metal recovery, and save flotation reagents.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
