Description

Technical Field

[0001] The utility model belongs to the technical field of centrifugal filtration, and particularly relates to a centrifugal filtration device. Background Art

[0002] A centrifugal filtration device is a device that uses centrifugal force to separate solid particles from a suspension in a liquid, achieving solid-liquid separation and being widely used in various industrial and scientific research fields. However, the existing centrifugal filtration devices often cannot filter the liquid after filtration again, so impurities will remain in the liquid, thereby affecting the purity of the liquid and the efficiency of solid-liquid separation. Moreover, it is not easy to clean after solid-liquid separation. Therefore, in view of the above problems, we propose a centrifugal filtration device. Content of the Utility Model

[0003] In view of the above problems, the purpose of the present utility model is to provide a centrifugal filtration device that can simultaneously perform secondary filtration on the liquid after filtration, improve the purity of the liquid and the efficiency of solid-liquid separation, and is easy to clean.

[0004] To achieve the above purpose, the technical solution adopted by the present utility model is: a centrifugal filtration device, including a processing barrel, a filtering member, and a driving component. The upper end of the processing barrel is detachably connected with a barrel cover. A liquid inlet pipe is provided in the middle of the barrel cover, and one end of the liquid inlet pipe extends into the interior of the processing barrel. The filtering member includes a first filter barrel and a second filter barrel located inside the first filter barrel. Both the first filter barrel and the second filter barrel are movably connected inside the processing barrel. The driving component is arranged at the bottom of the processing barrel and is used to drive the first filter barrel and the second filter barrel to rotate in opposite directions simultaneously.

[0005] The beneficial effect of the present utility model is: by fixing the barrel cover on the upper end of the processing barrel, and then starting the driving component to drive the mounting seat and the rotating rod to rotate in opposite directions simultaneously, the first filter barrel and the second filter barrel rotate in opposite directions simultaneously, so that the suspension is filtered by the second filter barrel and then enters the first filter barrel for secondary filtration, improving the filtration efficiency. At the same time, it is convenient to clean the movably arranged first filter barrel and the second filter barrel.

[0006] In order to drive the first filter barrel and the second filter barrel to rotate in opposite directions simultaneously;

[0007] As a further improvement of the above technical solution: the driving component includes a first driven gear connected to the bottom of the mounting seat, a second driven gear located below the first driven gear and connected to the rotating rod, and a driving gear meshing between the first driven gear and the second driven gear. A driving rod is connected to the middle of the driving gear, and a motor is connected to the driving rod.

[0008] The beneficial effect of this improvement is that when filtering is performed, the motor drives the driving rod to rotate, and the driving rod drives the active gear to rotate. At this time, the slave gear one and the slave gear two rotate in the opposite direction, and respectively drive the mounting seat and the rotating rod to rotate. At this time, the filter barrel one and the filter barrel two, which are movably connected to the mounting seat and the rotating rod, respectively, rotate in the opposite direction at the same time, driving the suspension to be filtered. The filter barrel one and the filter barrel two, which are arranged in opposite directions, when the suspension is filtered by the filter barrel two and then thrown into the filter barrel one, the impurities are easier to be separated due to the shear force generated by the reverse rotation, thereby achieving secondary thorough filtration.

[0009] In order to facilitate the disassembly and assembly of filter barrel 1 and filter barrel 2;

[0010] As a further improvement of the above technical solution: the upper ends of the mounting seat and the rotating rod are both provided with square grooves, and the bottoms of the filter barrels 1 and 2 are both provided with square blocks that match the square grooves.

[0011] The beneficial effect of this improvement is: when filter barrel one and filter barrel two need to be installed and used, first insert the square block at the bottom of filter barrel one into the square groove on the mounting seat. At this time, the rotating rod passes through the bottom of filter barrel one, and then the square block at the bottom of filter barrel two is inserted into the square groove on the rotating rod. It can rotate with the mounting seat and the rotating rod, which is convenient for vertical disassembly and assembly.

[0012] To reduce the impact of water flow;

[0013] As a further improvement of the above technical solution: a conical portion is provided on the inner bottom surface of the filter barrel 2, and the upper end of the conical portion corresponds to the liquid inlet pipe.

[0014] The beneficial effect of this improvement is that the setting of the conical part can guide the impurities settled at the bottom of the filter barrel 2. When the suspension enters the interior of the filter barrel 2 through the liquid inlet pipe, the impact of the water flow on the impurities can be reduced, and the re-suspension of the impurities can be reduced.

[0015] In order to facilitate the export of the filtered liquid;

[0016] As a further improvement of the above technical solution: the lower end of the processing tube is connected to a water outlet pipe, and a valve is provided on the water outlet pipe.

[0017] The beneficial effect of this improvement is that all the liquid after filtration will enter the treatment barrel, at which time the valve is opened and the filtered liquid can flow out from the water outlet pipe.

[0018] In order to facilitate the support of the treatment barrel;

[0019] As a further improvement of the above technical solution: a support seat is provided at the bottom of the processing barrel, the driving assembly is arranged inside the support seat, and one end of the rotating rod is rotatably connected to the support seat.

[0020] The beneficial effects of this improvement are as follows: The setting of the support base can support the processing barrel, increase the stability of the processing barrel, and facilitate the protection of the driving component at the same time. Description of the Drawings

Detailed Implementation Manner

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present utility model.

[0028] As Figures 1-5 shown, a centrifugal filtration device includes a processing barrel 1, a filtering member, and a driving component. The upper end of the processing barrel 1 is detachably connected with a barrel cover 2. A liquid inlet pipe 3 is provided in the middle of the barrel cover 2. One end of the liquid inlet pipe 3 extends into the interior of the processing barrel 1. The filtering member includes a first filter barrel 401 and a second filter barrel 402 located inside the first filter barrel 401. Both the first filter barrel 401 and the second filter barrel 402 are movably connected to the interior of the processing barrel 1. The driving component is arranged at the bottom of the processing barrel 1 and is used to drive the first filter barrel 401 and the second filter barrel 402 to rotate in opposite directions simultaneously;

[0029] Specifically, the surfaces of the first filter barrel 401 and the second filter barrel 402 have filter holes, and the filter holes on the first filter barrel 401 are smaller than those on the second filter barrel 402. The barrel cover 2 can be detachably connected to the treatment barrel 1 by means of threaded connection, snap connection, etc., which is convenient for opening the barrel cover 2 to clean the impurities inside the filter element. When centrifugal filtration is required, the barrel cover 2 is connected to the treatment barrel 1 to prevent liquid splashing during centrifugation. When the barrel cover 2 is connected to the treatment barrel 1, the drive assembly is activated to rotate the first filter barrel 401 and the second filter barrel 402. By connecting the liquid inlet pipe 3 to an external pipeline, the suspension first enters the interior of the second filter barrel 402 through the liquid inlet pipe 3. At this time, the rotating second filter barrel 402 centrifuges the suspension, and the liquid is thrown into the first filter barrel 401 through the surface of the second filter barrel 402. Then, the impurities are left on the surface of the second filter barrel 402. At this time, when the liquid enters the first filter barrel 401, the first filter barrel 401 that rotates in the opposite direction to the second filter barrel 402, due to the shear force generated by the reverse rotation, makes the liquid filtered by the second filter barrel 402 more easily filtered when it is filtered again by the first filter barrel 401. Then, the first filter barrel 401 throws the filtered liquid into the treatment barrel 1, and the impurities remain in the first filter barrel 401. At this time, the liquid in the treatment barrel 1 is clear liquid. The secondary filtration improves the efficiency of solid-liquid separation, and the first filter barrel 401 and the second filter barrel 402 that are movably connected are convenient for cleaning the filter cake therein after filtering the suspension, realizing its easy cleaning.

[0030] Preferably, the drive assembly includes a first driven gear 801 connected to the bottom of the mounting seat 5, a second driven gear 802 located below the first driven gear 801 and connected to the rotating rod 6, and a driving gear 803 meshing between the first driven gear 801 and the second driven gear 802. The middle of the driving gear 803 is connected to a driving rod 9, and a motor 10 is connected to the driving rod 9. When filtering, the motor 10 drives the driving rod 9 to rotate, the driving rod 9 drives the driving gear 803 to rotate. At this time, the first driven gear 801 and the second driven gear 802 rotate in opposite directions and drive the mounting seat 5 and the rotating rod 6 to rotate respectively. At this time, the first filter barrel 401 and the second filter barrel 402 that are movably connected to the mounting seat 5 and the rotating rod 6 rotate in opposite directions at the same time, driving the suspension for filtration. The first filter barrel 401 and the second filter barrel 402 arranged in reverse directions, when the suspension is thrown into the first filter barrel 401 after being filtered by the second filter barrel 402, due to the shear force generated by the reverse rotation, the impurities are more easily separated, thus realizing thorough secondary filtration.

[0031] Preferably, square grooves 11 are formed at the upper ends of the mounting base 5 and the rotating rod 6, and square blocks 12 adapted to the square grooves 11 are provided at the bottoms of the first filter barrel 401 and the second filter barrel 402. When the first filter barrel 401 and the second filter barrel 402 need to be installed and used, first insert the square block 12 at the bottom of the first filter barrel 401 into the square groove 11 on the mounting base 5. At this time, the rotating rod 6 passes through the bottom of the first filter barrel 401 and extends into the first filter barrel 401. Then insert the square block 12 at the bottom of the second filter barrel 402 into the square groove 11 on the rotating rod 6. While being able to rotate with the mounting base 5 and the rotating rod 6, it is convenient for vertical disassembly and assembly. The square block 12 and the square groove 11 can be set to have a relatively deep depth to increase the stability during centrifugal rotation.

[0032] Preferably, a conical portion 13 is provided on the inner bottom surface of the second filter barrel 402, and the upper end of the conical portion 13 corresponds to the liquid inlet pipe 3. The conical portion 13 can guide the impurities deposited at the bottom of the second filter barrel 402. When the suspension enters the interior of the second filter barrel 402 through the liquid inlet pipe 3, it can reduce the impact of the water flow on the impurities and reduce the re-suspension of the impurities.

[0033] Preferably, a water outlet pipe 14 is connected to the lower end of the treatment barrel, and a valve 15 is provided on the water outlet pipe 14. After filtration, all the liquid will enter the treatment barrel 1. At this time, open the valve 15, and the filtered liquid can flow out from the water outlet pipe 14.

[0034] Preferably, a support base 16 is provided at the bottom of the treatment barrel 1, the drive assembly is arranged inside the support base 16, and one end of the rotating rod 6 is rotatably connected to the support base 16. The support base 16 can support the treatment barrel 1, increase the stability of the treatment barrel 1, and at the same time facilitate the protection of the drive assembly.

[0035] Working principle and usage process of the present utility model: When using this device, first insert the square block 12 at the bottom of the first filter barrel 401 into the square groove 11 on the mounting seat 5 respectively. At this time, the rotating rod 6 passes through the through hole 7 and extends into the first filter barrel 401. Then insert the square block 12 at the bottom of the second filter barrel 402 into the square groove 11 on the rotating rod 6. Then cover the barrel cover 2 and start the motor 10. The motor 10 drives the driving rod 9 and the driving gear 803 to rotate. At this time, the first driven gear and the second driven gear rotate, and drive the mounting part and the rotating rod 6 to rotate respectively, realizing the simultaneous reverse rotation of the first filter barrel 401 and the second filter barrel 402. Then connect the suspension externally through the liquid inlet pipe 3, so that the suspension first enters the interior of the second filter barrel 402 and guides the impurities through the conical part 13. At this time, the rotating second filter barrel 402 centrifuges the suspension, and the liquid is thrown into the first filter barrel 401 through the surface of the second filter barrel 402. Then the impurities are left on the surface of the second filter barrel 402. At this time, the first liquid enters the first filter barrel 401, and then the first filter barrel 401 throws the filtered liquid into the treatment barrel 1, and the impurities are then left in the first filter barrel 401. At this time, the liquid in the treatment barrel 1 is clear liquid. By opening the valve 15, the filtered liquid in the treatment barrel 1 flows out. Then open the barrel cover 2, take out the first filter barrel 401 and the second filter barrel 402, and clean the filter cake on their inner walls. During the use of the present utility model, the filtered liquid can be filtered twice simultaneously, improving the purity of the liquid and the efficiency of solid-liquid separation, and being easy to clean.
