Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separators, in particular to a nickel ore hydrometallurgical solid-liquid separator. Background Art

[0002] Nickel ore hydrometallurgy is a metallurgical process that treats nickel ore by wet methods. It is a process that subjects nickel-containing ore to wet grinding, leaching, flotation, precipitation and other steps to extract and separate the nickel component. During the hydrometallurgical process, some waste or slag will be generated, which may contain a certain proportion of solid particles. The solid-liquid separator can separate these solid wastes from the liquid and dehydrate the solid part to reduce the volume of the waste, reduce the moisture content, and facilitate subsequent processing and disposal.

[0003] For example, the Chinese patent with announcement number CN207193368U discloses a solid-liquid separator for nickel ore hydrometallurgy, whose structure includes a tripod, a base, a frame, a guide wheel, a solid-liquid separation device, a feed hopper, an inner drum, and a motor. The upper end of the tripod is welded to the support frame, and the upper end of the support frame is connected to the frame by bolts. The upper end of the support frame is nested with a guide wheel, and the upper end of the guide wheel is fitted with the solid-liquid separation device. The upper end of the solid-liquid separation device is welded to the feed hopper. The solid-liquid separation device consists of a frame, a water filter plate, an extrusion roller, a dehydration chamber, a feed port, a main shaft, a transmission, a discharge port, and a water outlet. The above patent structurally sets up a solid-liquid separation device for nickel ore hydrometallurgy solid-liquid separation, and an extrusion roller and a water filter plate are set therein to squeeze each other for solid-liquid separation, so that effective solid-liquid separation can be carried out in nickel ore hydrometallurgy, making its solid-liquid separation more comprehensive, thereby improving the efficiency of nickel ore hydrometallurgy.

[0004] In the above patent, solid-liquid separation is performed by squeezing the squeezing roller and the water filter plate against each other, and the dehydrated material is discharged from the discharge port by the push of the squeezing roller. However, since crystal water or gelatin may exist between the solid particles of the nickel ore during the dehydration process, the viscosity of the material increases, which may cause the material to adhere to the discharge port to form a blockage, affecting the discharge speed.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The figure shows a nickel ore hydrometallurgical solid-liquid separator, which includes a support frame 1, a shell 2 arranged above the support frame 1, a feed pipe 4 arranged on the outer wall of the shell 2, a discharge pipe 5 arranged on the outer wall of the shell 2, a filter cartridge 3 arranged inside the shell 2, and an extrusion roller 6 rotatably installed inside the filter cartridge 3.

[0020] Existing: Chinese patent with announcement number CN207193368U discloses a solid-liquid separator for nickel ore hydrometallurgy. This patent discloses technical means of a tripod, a base, a frame, a guide wheel and a solid-liquid separation device. The support frame 1, the shell 2, the feed pipe 4, the discharge pipe 5, the filter cartridge 3 and the extrusion roller 6 in the present application document adopt the same technical means in the prior art, and this technical means will not be repeated here.

[0021] A transmission rod 7 is rotatably mounted on the outer wall of the shell 2, and the axial end of the transmission rod 7 is fixedly connected to the axial end of the extrusion roller 6. The outer wall of the shell 2 is provided with a knocking component for knocking the discharge pipe 5, and the outer wall of the support frame 1 is provided with a blowing component for blowing air into the discharge pipe 5.

[0022] When solid particles adhere to the inner wall of the discharge pipe 5 and affect the discharge speed, the discharge pipe 5 can be knocked by the set knocking component, which can effectively reduce the adhesion between the solid particles and the inner wall of the discharge pipe 5 and shake off the solid particles adhered to the inner wall of the discharge pipe 5.

[0023] After the knocking component knocks on the discharge pipe 5 to reduce the adhesion between the solid particles and the inner wall of the discharge pipe 5, an air flow can be blown into the inside of the discharge pipe 5 through the provided blowing component to further blow off the solid particles adhering to the inner wall of the discharge pipe 5, thereby ensuring the discharge speed and effectively reducing the situation where the material adheres to the discharge port to form a blockage, thereby affecting the discharge speed.

[0024] The knocking assembly includes a knocking hammer 8, a connecting rod 9, a rotating rod 10 and a cam 11. The connecting rod 9 is rotatably mounted on the outer wall of the shell 2, the knocking hammer 8 is fixedly mounted on the end of the connecting rod 9, the rotating rod 10 is rotatably mounted on the outer wall of the shell 2, the cam 11 is fixedly mounted on the outer wall of the rotating rod 10, the end of the cam 11 is adapted to the outer wall of the connecting rod 9, and the rotation of the rotating rod 10 is controlled by the rotation of the transmission rod 7.

[0025] By rotating the cam 11, the end of the cam 11 can be driven to come into contact with the surface of the connecting rod 9, and then the connecting rod 9 can be driven to rotate in the direction away from the discharge pipe 5. The connecting rod 9 drives the percussion hammer 8 to separate from the discharge pipe 5. Continuing to rotate the cam 11 can separate the end of the cam 11 from the surface of the connecting rod 9. The connecting rod 9 and the percussion hammer 8 rotate in the direction close to the discharge pipe 5 under the action of gravity until the percussion hammer 8 falls and hits the surface of the discharge pipe 5. Repeating the above operation, the percussion hammer 8 can reciprocate and knock on the discharge pipe 5.

[0026] The outer wall of the rotating rod 10 is connected to the outer wall of the transmission rod 7 through a belt and a pulley.

[0027] In the present embodiment, since the outer wall of the rotating rod 10 is connected to the outer wall of the transmission rod 7 by a belt and a pulley, when the transmission rod 7 rotates, it can drive the rotating rod 10 to rotate synchronously, so that the rotation of the squeezing roller 6 and the operation of the knocking component use the same power source, which saves energy and further improves the convenience of using the device.

[0028] A driving motor 12 is fixedly mounted on the outer wall of the support frame 1 , and an output shaft of the driving motor 12 is fixedly connected to an axial end of the transmission rod 7 .

[0029] In this embodiment: the drive motor 12 can be a common servo motor in the prior art, and its specific model can be determined according to actual usage requirements. No further details will be given here. By controlling the output shaft of the drive motor 12 to rotate, the transmission rod 7 can be driven to rotate, providing power for the rotation of the transmission rod 7 and the rotating rod 10.

[0030] The blowing assembly includes a blowing pipe 13, a hose 14, an air pump 15 and an air inlet pipe 16. The blowing pipe 13 is fixedly installed on the outer wall of the discharge pipe 5, the hose 14 is fixedly installed on the end of the blowing pipe 13 away from the discharge pipe 5, the air pump 15 is fixedly installed on the outer wall of the support frame 1, the end of the hose 14 away from the blowing pipe 13 is fixedly connected to the outlet end of the air pump 15, and the air inlet pipe 16 is fixedly installed on the inlet end of the air pump 15.

[0031] In this embodiment, when the hammer 8 strikes the discharge pipe 5 reciprocatingly, the discharge pipe 5 will vibrate to a certain extent. The hose 14 provided can better adapt to the striking component and reduce the impact of the vibration on the air pump 15.

[0032] By controlling the operation of the air pump 15, external air can be introduced from the air inlet pipe 16, and then the air is blown into the discharge pipe 5 through the hose 14 and the air blowing pipe 13 to form an airflow, further blowing off the solid particles adhering to the inner wall of the discharge pipe 5.

[0033] A one-way valve 17 is provided inside the air blowing pipe 13 .

[0034] In this embodiment, the one-way valve 17 is provided to allow airflow to enter the interior of the discharge pipe 5, while solid particles in the discharge pipe 5 will not enter the interior of the blowing pipe 13, so that the interior of the blowing pipe 13 remains unobstructed.

[0035] A collecting box 18 for containing materials is arranged below the discharge pipe 5 .

[0036] In this embodiment: a through hole for inserting the discharge pipe 5 is provided on the top surface of the collecting box 18 , and the dehydrated solid particles can be collected through the provided collecting box 18 .

[0037] Working principle: When it is necessary to separate the nickel ore particles into solid and liquid, the material is first put into the filter cartridge 3 through the feed pipe 4, and then the output shaft of the drive motor 12 is controlled to rotate, which can drive the transmission rod 7 and the extrusion roller 6 to rotate. The rotation of the extrusion roller 6 can drive the material to be pushed in the direction close to the discharge pipe 5. The surface of the extrusion roller 6 is inclined. Through the cooperation between the extrusion roller 6 and the filter cartridge 3, the moisture in the material can be squeezed out. The squeezed liquid seeps out of the filter cartridge 3 and falls into the lower part of the shell 2. The outer wall of the shell 2 is provided with a water hole, and the squeezed liquid finally flows out through the water hole. The dehydrated material falls into the collection box 18 from the discharge pipe 5 for internal storage, which is convenient for the staff to carry out subsequent processing of the solid particles and the liquid respectively.

[0038] At the same time, through the set knocking assembly, the rotation of the transmission rod 7 can drive the cam 11 to rotate, and then the knocking hammer 8 can reciprocately knock on the discharge pipe 5, which can effectively reduce the adhesion between the solid particles and the inner wall of the discharge pipe 5, and shake off the solid particles adhering to the inner wall of the discharge pipe 5.

[0039] After the knocking component knocks on the discharge pipe 5 to reduce the adhesion between the solid particles and the inner wall of the discharge pipe 5, by controlling the air pump 15 to work, the outside air can be introduced from the air inlet pipe 16, and then through the hose 14 and the blowing pipe 13, the air is formed into an airflow and blown to the inside of the discharge pipe 5, further blowing off the solid particles adhering to the inner wall of the discharge pipe 5, ensuring the discharge speed and effectively reducing the situation where the material adheres to the discharge port to form a blockage, affecting the discharge speed.
