Description

Technical Field

[0001] This utility model belongs to the technical field of mineral sorting equipment, specifically, it relates to a large-scale solid-liquid separation device with a modular opposing structure. Background Technology

[0002] In the production and processing of minerals and metals, solid-liquid separation is often required to separate liquids containing suspended solid particles. This process separates the solid particles from the liquid to obtain a pure liquid product or to further process the solid particles.

[0003] In some application scenarios, the supply pressure of the feed slurry to be sorted is unstable, making it impossible to use a conventional feed distributor for material distribution. Using a feed tank would further increase the size of the equipment, raise the center of gravity of the equipment, make the equipment unstable and prone to vibration during operation, and affect the life of the equipment. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, this utility model provides an improved solid-liquid separation device to make the device structure more balanced and stable and reduce operating vibration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large solid-liquid separation device with a modular opposing structure includes a bottom flow channel, an overflow channel, a feed tank, and several working groups arranged coaxially from bottom to top around the overflow channel. The feed tank located above the overflow channel and the several working groups arranged around the overflow channel cooperate with each other to balance the overall load of the device.

[0007] According to this invention, the feed tank has a plurality of distribution ports distributed circumferentially, the number of which is the same as the number of the working groups, and each distribution port is connected to a working group in a one-to-one correspondence. The distribution ports are arranged in a balanced structure with the equipment axis as the reference.

[0008] According to a preferred embodiment of the present invention, the working group includes a first working group and five second working groups. The first working group is composed of a single hydrocyclone, and the second working group is composed of two hydrocyclones. The first working group is connected to the feed tank through a first feed distribution pipe, and the second working group is connected to the feed tank through a second feed distribution pipe.

[0009] According to this utility model, the cross-section of the feed tank is approximately elliptical, and the upper and lower parts of the tank body have a gradually decreasing inner diameter. The bottom end of the tank body is the feed inlet, and the feed pipe connected to the feed inlet extends to the bottom of the equipment. The top opening of the tank body is closed by a top cover.

[0010] Preferably, the top cover is also equipped with a pressure gauge and a pressure relief pipe to monitor the internal pressure of the feed tank and to relieve pressure when the pressure is too high.

[0011] According to this utility model, with the axis of the equipment as a reference, four partitions are divided in planar space along the X and Y axes: I, II, III, and IV; the middle of the tank is provided with a first distribution port, a second distribution port, a third distribution port, a fourth distribution port, and a fifth distribution port for connecting to the second working group, wherein:

[0012] The first and fourth distribution ports are located on the Y-axis, forming a first set of opposing ports to balance the load on opposite sides of the feed tank during operation.

[0013] The second, third, and fifth distribution ports are located at equal angles on partitions II, III, and IV, respectively, with an angle of 45° to the X and Y axes.

[0014] The first partition is also provided with a sixth distribution port and a seventh distribution port for observing the working conditions. The plane angles between the axis of the sixth distribution port and the seventh distribution port and the axis of the third distribution port are 31° and 10°, respectively.

[0015] According to this utility model, the inner surface of the feed tank is also coated with a zinc powder ethyl silicate anti-corrosion layer to improve its corrosion resistance.

[0016] This utility model discloses a large-scale solid-liquid separation device with a modular opposing structure. By fixing the hydrocyclones in a modular annular opposing structure on the outer periphery of the overflow tank, the device structure becomes more balanced and stable, reducing operational vibration. At the same time, a protective layer is set inside the feed tank to make the device conform to ISO 12944-2 and improve its durability. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0023] like Figure 1 and Figure 2 The diagram shows the overall structure of the large-scale solid-liquid separation device with a modular opposing structure according to this invention. It includes a bottom flow channel 10, an overflow channel 20, a feed tank 30, and several working groups 40 arranged coaxially from bottom to top around the overflow channel 20. Each working group 40 consists of one or more hydrocyclones 41, whose inlets are connected to the feed tank 30 via pipelines to obtain the mixture to be separated from the solid. The top and bottom outlets are connected to the overflow channel 20 and the bottom flow channel 10, respectively, via pipelines. The structure of the hydrocyclones 41 is well-known in the prior art and will not be described in detail here. The feed tank 30 located above the overflow channel 20 and the several working groups 40 arranged around the overflow channel 20 cooperate with each other to balance the overall load of the device.

[0024] Furthermore, the feed tank 30 has a plurality of distribution ports distributed circumferentially, the number of which is the same as the number of the working groups 40, and each distribution port is connected to one working group 40 in a one-to-one correspondence. The distribution ports are arranged in a balanced structure with the equipment axis as the reference.

[0025] The working group 40 includes a first working group 42 and several second working groups 43. The first working group consists of a single hydrocyclone 41, and each second working group 43 consists of two hydrocyclones 41. In this embodiment, there are five second working groups 43. The first working group 42 is connected to the feed tank 30 through a first feed distribution pipe 44, and the second working groups 43 are connected to the feed tank 30 through a second feed distribution pipe 45. Preferably, each working group 40 is provided with a protective cover 46 on its outer side to protect the equipment from damage.

[0026] like Figure 3As shown, the cross-section of the feed tank 30 is approximately elliptical. The upper part 32 and lower part 33 of the tank body 31 both exhibit a gradually decreasing inner diameter configuration. The bottom end of the tank body 31 is the feed inlet 34, and the feed pipe 35 connected to the feed inlet 34 extends to the bottom of the equipment. Figure 1 ); combined Figure 2 As shown, the top opening of the tank 31 is closed by a top cover 36, which is also equipped with a pressure gauge 37 and a pressure relief pipe 38 to monitor the internal pressure of the feed tank 30 and relieve pressure when it is too high. The gradually narrowing inner diameter of the lower part 33 of the feed tank 30, combined with the feed pipe 35 supplying material through the bottom of the feed tank 30, allows the material to enter the feed inlet 34 of the feed tank 30 and then enter a funnel-shaped configuration, which can buffer the fluctuation of the feed liquid, balance the feed rate, and make the material have relatively uniform properties.

[0027] like Figure 4 As shown, with the equipment's axis as a reference, four zones are divided in planar space along the X and Y axes: I, II, III, and IV. The tank body 31 has a first distribution port 311, a second distribution port 312, a third distribution port 313, a fourth distribution port 314, and a fifth distribution port 315 for connection to the second working group 41. The first distribution port 311 and the fourth distribution port 314 are located on the Y-axis, forming a first group of opposing ports to balance the load on opposite sides of the feed tank 30 during operation. The second distribution port 312, the third distribution port 313, and the fifth distribution port 315 are equidistantly located on zones II, III, and IV, respectively, forming an angle of 45° with the X and Y axes. The first partition is also equipped with a sixth distribution port 316 and a seventh distribution port 317 for observing the working conditions. Since the workload in the second working group 42 is much smaller than that in the first working group 41, the diameter of the sixth distribution port 316 is also smaller than that of the first distribution port 311, the second distribution port 312, the third distribution port 313, the fourth distribution port 314, and the fifth distribution port 315. The plane angles between the axes of the sixth distribution port 316 and the seventh distribution port 317 and the third distribution port 313 are 31° and 10°, respectively, so that the four partitions can achieve a balanced load during operation.

[0028] Since the mass of the multiple hydrocyclones 41 in the working group 40 is greater than that of the components of the central structure of the equipment (such as the underflow channel 10 and the overflow channel 20), in order to achieve overall balanced operation of the equipment, the hydrocyclones 41 are mounted outside the overflow channel 20, so that the overall center of gravity is lowered. In conjunction with the above-mentioned circumferential distribution structure, the machine is prevented from mechanical vibration caused by uneven load, thereby reducing its service life.

[0029] Preferably, the inner surface of the feed tank 30 is also coated with a zinc powder ethyl silicate anti-corrosion layer (not shown in the figure) to improve its corrosion resistance, such as the corrosive hydroxide compound produced by mixing aluminum oxide with water.

[0030] Although the present invention has been described in detail above through specific embodiments, it should be understood that the above description is only a preferred embodiment of the present invention. Those skilled in the art can make appropriate modifications, equivalent substitutions and improvements within the spirit and principles of the present invention, all of which should be included within the protection scope of the present invention.
