Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal dehydration devices, in particular to a rapid centrifugal dehydration device used in metallurgy. Background Art

[0002] Hydrometallurgy is the process of bringing ore or other raw materials into contact with aqueous solutions or other liquids, transferring the useful metals contained in the raw materials into the liquid phase through chemical reactions, and then separating and collecting the various useful metals contained in the liquid phase, and finally recovering them in the form of metals or other compounds. After the original ore has undergone hydrometallurgical operations, it is necessary to separate and dehydrate the original ore from the liquid and collect the liquid.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-6 The figure shows a metallurgical rapid centrifugal dehydration device, which includes a dehydration box 1, a filter cartridge 3 for dehydrating materials, a cover plate 12 rotatably mounted on the outer wall of the filter cartridge 3, a filter plate 10 slidably mounted inside the dehydration box 1, and a liquid outlet pipe 11 fixedly mounted on the outer wall of the dehydration box 1.

[0024] Existing: Chinese patent with announcement number CN215744144U discloses a rapid centrifugal dehydration device for hydrometallurgy. This patent discloses the technical means of a shell, a drum, a screen, a cover plate, a filter screen, a guide plate, a liquid outlet pipe and a valve. The dehydration box 1, the filter cartridge 3, the cover plate 12, the filter plate 10 and the liquid outlet pipe 11 in the present application document adopt the same technical means in the prior art, and this technical means will not be repeated here one by one.

[0025] The outer wall of the dehydration box 1 is slidably mounted with a mounting plate 2, and two mounting plates 2 are provided. The outer wall of the dehydration box 1 is provided with a sliding groove for the mounting plate 2 to slide. The outer wall of the mounting plate 2 slides in contact with the inner wall of the sliding groove, which is beneficial to improve the stability of the mounting plate 2 when sliding.

[0026] A rotation groove for the filter cartridge 3 to rotate is formed on the outer wall of one of the mounting plates 2 , and a bearing is provided on the inner wall of the rotation groove. The inner wall of the bearing is movably connected to the outer wall of the filter cartridge 3 .

[0027] A first motor 14 is fixedly mounted on the outer wall of another mounting plate 2, and an output shaft of the first motor 14 is fixedly connected to a connecting block 13. The first motor 14 here can be a servo motor commonly used in the prior art, and its specific model can be determined according to actual usage requirements, which will not be elaborated here.

[0028] The outer wall of the filter cartridge 3 is provided with a connecting component for connecting to the connecting block 13. Through the provided connecting component, the filter cartridge 3 and the connecting block 13 can be installed or disassembled, which is convenient for the staff to remove the filter cartridge 3 and clean or replace the filter cartridge 3.

[0029] The interior of the dewatering box 1 is provided with a shaking component for shaking the filter cartridge 3. Through the setting of the shaking component, the two mounting plates 2 and the filter cartridge 3 can be controlled to rise or fall synchronously to achieve a shaking effect, which can help shake off the metallurgical ore stuck on the filter cartridge.

[0030] The shaking assembly includes a first spring 9, a guide rail 7 and a pushing block 6 for pressing the guide rail 7. The first spring 9 is fixedly installed on the inner wall of the sliding groove. The other end of the first spring 9 is fixedly connected to the outer wall of the mounting plate 2. The pushing block 6 is rotatably installed inside the dehydration box 1, and the guide rail 7 is fixedly installed on the outer wall of the filter cartridge 3.

[0031] A plurality of first springs 9 are arranged, and the plurality of first springs 9 are evenly distributed on the outer wall of the mounting plate 2 . The guide rail 7 arranged can prevent the push block 6 from directly contacting the surface of the filter cartridge 3 , causing wear on the surface of the filter cartridge 3 and affecting the water filtering effect of the filter cartridge 3 .

[0032] When metallurgical ore accumulates on the surface of the filter cartridge 3, the push block 6 can be rotated to drive the raised portion of the push block 6 to be squeezed with the guide rail 7, thereby driving the guide rail 7, the filter cartridge 3 and the two mounting plates 2 to slide downward. At this time, the two mounting plates 2 will squeeze the first spring 9, so that the first spring 9 stores elastic potential energy. When the raised portion of the push block 6 is separated from the guide rail 7, combined with the elastic force of multiple first springs 9, the filter cartridge 3 and the two mounting plates 2 can be driven to shake up and down multiple times, which is beneficial to destroy the adhesion between the metallurgical ore and the filter cartridge 3, so that the metallurgical ore is loosened and falls from the filter holes of the filter cartridge 3.

[0033] A rotating rod 17 is rotatably installed on the inner wall of the dehydration box 1 , and the outer wall of the rotating rod 17 is fixedly connected to the outer wall of the pushing block 6 . A second motor 18 is fixedly connected to the outer wall of the dehydration box 1 , and the output shaft of the second motor 18 is fixedly connected to the axial end of the rotating rod 17 .

[0034] There are multiple pushing blocks 6, and the number of guide rails 7 corresponds to the number of pushing blocks 6. By rotating the rotating rod 17, multiple pushing blocks 6 can be driven to rotate synchronously. The second motor 18 here can be a servo motor commonly used in the prior art. Its specific model can be determined according to actual usage requirements, and no further details will be given here. By controlling the output shaft of the second motor 18 to rotate, the rotating rod 17 can be driven to rotate, thereby providing power for the rotation of multiple pushing blocks 6.

[0035] The connecting assembly includes a connecting rod 15 and a second spring 16. A guide groove is provided inside the filter cartridge 3. The connecting rod 15 is slidably installed inside the guide groove. The second spring 16 is fixedly installed on the inner wall of the guide groove. One end of the second spring 16 away from the guide groove is fixedly connected to the outer wall of the connecting rod 15. The outer wall of the connecting block 13 is provided with an L-shaped groove for inserting the connecting rod 15.

[0036] One end of the connecting rod 15 passes through the outer wall of the filter cartridge 3 , and the other end of the connecting rod 15 passes through the L-shaped groove of the connecting block 13 . Two connecting assemblies are provided, and the two connecting assemblies are symmetrically distributed on the outer wall of the filter cartridge 3 .

[0037] When the staff needs to replace the filter cartridge 3, by sliding the two connecting rods 15 in relative directions, the other ends of the two connecting rods 15 can be driven into the L-shaped groove. Then, the staff can pull the filter cartridge 3 out of the dehydration box 1, and the filter cartridge 3 and the connecting block 13 can be disassembled, making it convenient for the staff to clean or replace the surface of the filter cartridge 3.

[0038] On the contrary, when the staff needs to install the filter cartridge 3, first place the filter cartridge 3 into the dehydration box 1, then slide the two connecting rods 15 in relative directions, align the other ends of the two connecting rods 15 with the L-shaped groove of the connecting block 13, and insert the other ends of the two connecting rods 15 into the L-shaped groove. Through the elastic force of the second spring 16, the other ends of the two connecting rods 15 can be passed through the L-shaped groove to achieve the installation between the filter cartridge 3 and the connecting block 13.

[0039] The outer wall of the mounting plate 2 is fixedly connected with a first baffle 4 for shielding the sliding groove, the outer wall of the mounting plate 2 is fixedly connected with a second baffle 5 for shielding the sliding groove, and the inner wall of the sliding groove is provided with a receiving groove for the second baffle 5 to slide.

[0040] When the mounting plate 2 slides upward or downward, the first baffle plate 4 and the second baffle plate 5 can effectively shield the interior of the sliding groove, thereby improving the sealing performance of the interior of the dehydration box 1 and the collection rate of the liquid.

[0041] The inner wall of the sliding groove is fixedly connected with a guide rod 8 , the outer wall of the mounting plate 2 is provided with a first through hole for the guide rod 8 to pass through, and the outer wall of the second baffle plate 5 is provided with a second through hole for the guide rod 8 to pass through.

[0042] Through the cooperation between the guide rod 8, the first through hole and the second through hole, the stability of the mounting plate 2, the second baffle plate 5 and the first baffle plate 4 when sliding can be effectively improved, and the shaking generated when the mounting plate 2, the second baffle plate 5 and the first baffle plate 4 slide can be reduced.

[0043] Working principle: When the metallurgical ore needs to be dehydrated, the output shaft of the first motor 14 is controlled to rotate, which can drive the connecting block 13 and the filter cartridge 3 to rotate quickly. Under the action of centrifugal force, the liquid in the metallurgical ore can be thrown out, and the impurities mixed in the liquid can be filtered through the filter plate 10. Finally, the collected liquid flows out from the inside of the liquid outlet pipe 11, which is convenient for the staff to handle it.

[0044] When metallurgical ore accumulates on the surface of the filter cartridge 3, the push block 6 can be rotated to drive the raised portion of the push block 6 to squeeze the guide rail 7, thereby driving the guide rail 7, the filter cartridge 3 and the two mounting plates 2 to slide downward. At this time, the two mounting plates 2 will squeeze the first spring 9, so that the first spring 9 stores elastic potential energy. When the raised portion of the push block 6 is separated from the guide rail 7, combined with the elastic force of multiple first springs 9, the filter cartridge 3 and the two mounting plates 2 can be driven to shake up and down multiple times, which is beneficial to destroy the adhesion between the metallurgical ore and the filter cartridge 3, causing the metallurgical ore to loosen and fall from the filter holes of the filter cartridge 3.

[0045] When the shaking assembly has difficulty in shaking off the metallurgical ore accumulated on the surface of the filter cartridge 3, the staff can slide the two connecting rods 15 in relative directions to drive the other ends of the two connecting rods 15 into the L-shaped groove. Then, the staff can pull the filter cartridge 3 out of the dehydration box 1, and the disassembly between the filter cartridge 3 and the connecting block 13 can be achieved, which makes it convenient for the staff to clean or replace the surface of the filter cartridge 3, further improving the convenience of using the device and the cleaning effect of the filter cartridge 3.

[0046] On the contrary, when the staff needs to install the filter cartridge 3, they first place the filter cartridge 3 into the dehydration box 1, and then slide the two connecting rods 15 in relative directions and insert the other ends of the two connecting rods 15 into the L-shaped groove. Through the elastic force of the second spring 16, the other ends of the two connecting rods 15 can be passed through the L-shaped groove to achieve the installation of the filter cartridge 3.

[0047] Compared with the Chinese patent with announcement number CN215744144U, which discloses a rapid centrifugal dehydration device for hydrometallurgy, the screw pad and the screw rod in the above patent are located inside the shell, while one end of the connecting rod 15 in the connecting assembly of the present device passes through the outer wall of the filter cartridge 3, which can be more convenient for the staff to operate. At the same time, the present device increases the shaking effect on the filter cartridge 3, which is beneficial to destroy the adhesion between the metallurgical ore and the filter cartridge 3, causing the metallurgical ore to loosen and fall from the filter holes of the filter cartridge 3, thereby ensuring the water filtering effect of the filter cartridge 3.

Moreover, the terms "include"-"comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process-method-article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process-method-article or device.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
