Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a centrifuge for producing pharmaceutical raw materials. Background Art

[0002] The main principle of the centrifuge is to use the centrifugal force generated by the high-speed rotation of the centrifugal drum to accelerate the liquid phase in the solid-liquid mixture out of the drum, while leaving the solid phase in the drum, thereby achieving the effect of separating solids and liquids, or commonly known as dehydration.

[0003] The existing Chinese patent "A centrifuge for the preparation of pharmaceutical raw materials" with the announcement number CN212759164U proposes to limit the vibration frequency and amplitude of the centrifuge body by the elasticity of the elastic telescopic rod, and at the same time, to buffer the collision between the cylindrical air cushion of the air cushion support and the placement plane, thereby reducing the noise generated by the collision and ensuring the stability of the high-speed rotation of the centrifuge. However, in the actual production process, when the material touches the filter screen, the particle size will pass through the filter cylinder when it is smaller than the filter aperture of the filter screen, thereby achieving the separation effect. However, due to the fixed aperture of the screen, it is impossible to achieve complete separation and cannot meet the use requirements. There are certain shortcomings. For this reason, we propose a centrifuge for the production of pharmaceutical raw materials. Utility Model Content

[0004] The utility model aims to provide a centrifuge for producing pharmaceutical raw materials, which realizes graded filtration and improves the filtration effect.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A centrifuge for producing pharmaceutical raw materials comprises a box body, a third cover plate is arranged on the top of the box body, a feed pipe extending into the box body is arranged on the third cover plate, and a liquid discharge port is arranged on the side of the box body;

[0007] A first filter cartridge and a second filter cartridge are arranged in the box body, and the second filter cartridge is located in the first filter cartridge; a driving mechanism is embedded in the bottom of the box body, and the driving mechanism is connected with the first filter cartridge and the second filter cartridge to drive the first filter cartridge and the second filter cartridge to rotate;

[0008] A first cover plate is installed on the top of the first filter cartridge, a second cover plate is installed on the top of the second filter cartridge, and the feed pipe penetrates the first cover plate and the second cover plate to extend into the second filter cartridge.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The utility model arranges the first filter cartridge and the second filter cartridge to rotate, thereby facilitating the centrifugal separation of the pharmaceutical raw materials. The first filter cartridge and the second filter cartridge are separated separately, and the separation effect is good.

[0011] 2. The unique driving mechanism can realize the reverse rotation between the first filter cartridge and the second filter cartridge, further optimizing the separation effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] like Figure 1-3 The centrifuge for producing pharmaceutical raw materials comprises a box body 1, a third cover plate 10 is provided on the top of the box body 1, and a feed pipe 11 extending into the box body 1 is provided on the third cover plate 10, and a liquid discharge port 7 is installed on the side of the box body 1;

[0019] A first filter cartridge 5 and a second filter cartridge 6 are provided in the box body 1, and the second filter cartridge 6 is located in the first filter cartridge 5; a driving mechanism 3 is embedded in the bottom of the box body 1, and the driving mechanism 3 is connected to the first filter cartridge 5 and the second filter cartridge 6 to drive the first filter cartridge 5 and the second filter cartridge 6 to rotate;

[0020] A first cover plate 8 is installed on the top of the first filter cartridge 5 , a second cover plate 9 is installed on the top of the second filter cartridge 6 , and the feed pipe 11 penetrates the first cover plate 8 and the second cover plate 9 to extend into the second filter cartridge 6 .

[0021] Two-stage filtration can be achieved here to improve the filtering effect.

[0022] The filter hole diameter of the first filter cartridge 5 is smaller than the filter hole diameter of the second filter cartridge 6. Gradual filtration can be achieved.

[0023] The driving mechanism 3 includes a motor 4, a housing 31, a gear ring 32, a turntable 33, a first rotating shaft 34, a first gear 35, a second rotating shaft 36 and a second gear 37;

[0024] The motor 4 is installed at the bottom center of the housing 31;

[0025] The housing 31 is embedded in the bottom of the box 1, and the gear ring 32 is fixed inside the housing 31; the top of the housing 31 is rotatably connected to a turntable 33, and the bottom of the housing 31 is rotatably connected to a first rotating shaft 34, which is connected to the motor, and a first gear 35 is fixedly sleeved on the first rotating shaft 34;

[0026] The center of the turntable 33 is rotatably connected to a second shaft 36, on which a second gear 37 is fixedly sleeved, the first gear 35 and the second gear 37 are meshed with each other, and the first gear 35 is meshed with the gear ring 32;

[0027] The first rotating shaft 34 passes through the turntable 33 and is connected to the second filter cartridge 6 , and the turntable 33 is connected to the bottom surface of the first filter cartridge 5 .

[0028] Through the cooperation of the two gears and the gear ring, the first filter cartridge 5 and the second filter cartridge 6 can rotate in opposite directions, thereby ensuring the filtering effect.

[0029] When in use, the device is connected to a power source, the motor 4 is started, the output shaft of the motor 4 drives the second rotating shaft 36 to rotate, and the second rotating shaft 36 drives the second gear 37 and the second filter cartridge 6 to rotate;

[0031] The pharmaceutical raw materials enter the interior of the second filter cartridge 6 through the feed pipe 11, and are initially separated by centrifugal separation of the second filter cartridge 6. The separated raw materials are secondarily separated by the first filter cartridge 5, thereby fully separating the pharmaceutical raw materials. After separation, the liquid is discharged through the drain port 7, and residues are left in the first filter cartridge 5 and the second filter cartridge 6. The device has a simple structure, and the separation effect of pharmaceutical raw materials can be effectively improved through multi-stage separation.
