Description

Technical Field

[0001] The utility model relates to the field of gold concentrate, in particular to a thickener for separating multi-element gold concentrate slurry. Background Art

[0002] A pre-leaching thickener is a thickening device used before processes such as multi-element ore leaching. It primarily operates based on the principle of gravity settling. After the slurry enters the thickener, solid particles gradually settle to the bottom of the thickener under the action of gravity, while a clear liquid forms above. The purpose is to concentrate the slurry, increase the solid content in the slurry, reduce the processing volume of the subsequent leaching process, and at the same time recover part of the supernatant for recycling. For example, the Chinese patent document with the announcement number CN202638056U discloses a thickener, including a thickener tank, a thickener scraper located in the thickener tank, and a motor for driving the thickener scraper. The lower part of the thickener tank is a cone with the tip facing downward, and overflow ports are distributed circumferentially on the side wall of the top of the thickener tank. The output shaft of the motor is connected to the central rotating shaft of the thickener scraper. The middle part of the bottom wall of the thickener tank is opened, and a lower tank body with the same shape as the thickener tank is installed at the opening. A lower scraper is provided in the lower tank body, and the central rotating shaft of the lower scraper is connected to the bottom of the central rotating shaft of the thickener scraper. A discharge port is provided in the middle of the bottom wall of the lower tank body. The device cannot fully mix the slurry and flocculant, and has poor stirring ability, which urgently needs to be improved. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a thickener for separating multi-element gold concentrate slurry, including a tank body and a stirring assembly, the top of the tank body is open, the bottom of the tank body is provided with a discharge port, a positioning convex ring is fixedly provided above the tank body, the positioning convex ring includes a support plate and a limiting ring arranged coaxially with the tank body, a plurality of filter holes are provided on the support plate, a material mixing ring is rotatably provided between the outer wall of the limiting ring and the inner wall of the tank body, and a feed pipe is tangentially provided on the side wall of the tank body.

[0005] The utility model provides a thickener for separating multi-element gold concentrate slurry, which also has the following technical features:

[0006] Furthermore, the stirring assembly includes a support rod, a motor fixedly connected to the support rod, and a stirring shaft fixedly connected to the output end of the motor, a plurality of stirring plates are circumferentially fixedly provided in the middle part of the stirring shaft, and the bottom end of the stirring shaft extends into the discharge port and is circumferentially fixedly provided with a plurality of stirring rods.

[0007] Furthermore, the rotation speed of the motor is 80r / min.

[0008] Furthermore, the material leveling ring includes a rotating ring sleeved outside the limiting ring and a plurality of material shifting plates circumferentially fixedly arranged outside the rotating ring.

[0009] Furthermore, the tank body includes an upper cylindrical section, a conical section and a lower cylindrical section.

[0010] Furthermore, the support rod is connected to the top of the tank body by bolts.

[0011] The utility model has the following beneficial effects: since the feed pipe is arranged tangentially to the tank body, when a mixture of mineral material and flocculant can be pumped into the tank body through the feed pipe, the material leveling ring can be rotated to mix the mixture between the positioning convex ring and the tank body, and then the mixed material can be stirred again by the stirring assembly, thereby further promoting the precipitation and separation of the multi-element gold concentrate slurry.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0015] like Figures 1 to 2 The embodiment of a thickener for separating multi-element gold concentrate slurry of the present invention shown in the figure includes a tank body 1 and a stirring assembly 2. The top of the tank body 1 is open, and the bottom of the tank body 1 is provided with a discharge port. A positioning convex ring 3 is fixedly provided above the tank body 1. The positioning convex ring 3 includes a support plate 31 and a limiting ring 32 arranged coaxially with the tank body 1. A plurality of filtering holes 310 are provided on the support plate 31. A material mixing ring 4 is rotatably provided between the outer wall of the limiting ring 32 and the inner wall of the tank body 1. A feed pipe 5 is tangentially provided on the side wall of the tank body 1. Specifically, since the feed pipe 5 is tangentially arranged to the tank body 1, when a mixture of ore and flocculant can be pumped into the tank body 1 through the feed pipe 5, the material mixing ring 4 can be rotated to mix the mixture between the positioning convex ring 3 and the tank body 1. Then, the mixed material can be stirred again by the stirring assembly 2 to further promote the precipitation and separation of the multi-element gold concentrate slurry.

[0016] In one embodiment of the present application, the stirring assembly 2 includes a support rod 21, a motor 22 fixedly connected to the support rod 21, and a stirring shaft 23 fixedly connected to the output end of the motor 22. A plurality of stirring plates 24 are circumferentially fixedly provided in the middle part of the stirring shaft 23. The bottom end of the stirring shaft 23 extends into the discharge port and is circumferentially fixedly provided with a plurality of stirring rods 231. Specifically, when the motor 22 rotates, the motor 22 drives the stirring shaft 23 to rotate, and the stirring shaft 23 drives the stirring plate 24 to rotate to stir the mixture of the mineral material and the flocculant again. At the same time, the stirring shaft 23 drives the stirring rod 231 to rotate synchronously to avoid the material blocking the discharge port.

[0017] In one embodiment of the present application, the rotation speed of the motor 22 is 80 r / min.

[0018] In one embodiment of the present application, the material leveling ring 4 includes a rotating ring 41 that is sleeved on the outside of the limiting ring 32 and a plurality of material-dispensing plates 42 that are circumferentially fixedly arranged outside the rotating ring 41. Specifically, since the feed pipe 5 is arranged tangentially to the tank body 1, the material-dispensing plate 42 can be driven to rotate during feeding, and the material-dispensing plate 42 drives the synchronous rotation to achieve the purpose of preliminary mixing.

[0019] In one embodiment of the present application, the tank body 1 includes an upper cylindrical section 10 , a conical section 11 and a lower cylindrical section 12 .

[0020] In one embodiment of the present application, the support rod 21 is connected to the top of the tank body 1 by bolts.
