Description

Technical Field

[0001] This utility model relates to the field of centrifugation equipment technology, and in particular to a centrifugation equipment for the preparation of pharmaceutical intermediates. Background Technology

[0002] Centrifugation is a technique that involves rotating a solution at high speed around an axis, using centrifugal force to cause some components to precipitate while others remain in the supernatant. The circular motion of an object generates centrifugal force, and at the same rotation speed, due to the differences in density and mass of each component, the particles move tangentially through the action of centrifugal force, thereby achieving the effect of separating different components.

[0003] Chinese Patent CN222358618U discloses a centrifuge device for preparing pharmaceutical intermediates, including a centrifuge tank. Limiting slides are fixedly installed on both sides of the interior of the centrifuge tank. Limiting slip rings are slidably installed within the two sets of limiting slides. An inner sieving cylinder is fixedly installed inside the two sets of limiting slip rings. An extrusion mechanism is installed inside the inner sieving cylinder. The extrusion mechanism includes a guide cylinder connected to the bottom of the inner sieving cylinder. This invention uses a drive motor to rotate a gear, and the gear ring meshing with the gear rotates the inner sieving cylinder, centrifuging and sieving the materials inside. Simultaneously, a piston rod in the extrusion mechanism pushes the extrusion block at the bottom, continuously approaching the bottom of the inner sieving cylinder. This not only squeezes out the moisture contained in the material, further efficiently centrifuging and discharging the moisture, but also extrudes the dry material from the guide cylinder, improving the efficiency of material discharge after centrifugation.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: The above-mentioned solutions can improve the drug yield by combining squeezing and centrifugation, but in actual use, the drug needs to be balanced before centrifugation to ensure high-speed rotation stability. The above-mentioned devices are difficult to operate and the balancing is inaccurate during the drug balancing process. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] The purpose of this invention is to address the technical problems existing in the background art. This invention proposes a centrifuge device for the preparation of pharmaceutical intermediates. This invention can effectively improve the efficiency and accuracy of drug sample balancing in the centrifugation process. Because the amount of different samples used in centrifugation is often different, it is impossible to make the weights of the two samples completely consistent during balancing. Therefore, balancing cannot be achieved by simply placing them diagonally, which increases the difficulty of operation for medical personnel. This device can change the centrifugal force torque by changing the rotation radius during centrifugation through sliding adjustment, thereby achieving the effect of balancing samples of different weights.

[0007] This utility model proposes a centrifuge device for preparing pharmaceutical intermediates, including a shell, a sloping side of the shell, a display screen on the sloping side, and several equally spaced control buttons on the sloping side. A central control module is located inside the shell, and the central control module is communicatively connected to the display screen.

[0010] By adopting the above technical solution, this solution can effectively improve the stability of the balancing process of this device through the notch and sliding groove, thereby enabling centrifugal balancing of different samples of any different weight.

[0011] Preferably, a sliding column is slidably connected to the inner wall of the sliding groove, and a tray is connected to the other end of the sliding column, with a limiting hole provided on the top of the tray.

[0012] By adopting the above technical solution, this solution enables the tray to tilt and rotate outward of the rotating groove during centrifugal rotation through the rotating connection of the sliding column. At this time, the test tubes stored in the internal limiting hole will not fall out due to centrifugal force.

[0013] Preferably, a spring bracket is connected to the top of the tray, springs are symmetrically arranged on both sides of the spring bracket, a sliding member is connected to the other end of the spring, the bottom of the sliding member is slidably connected to the tray, and an arc-shaped limiting member is connected to the side of the sliding member away from the spring, with the arc-shaped limiting member facing the limiting hole.

[0014] By adopting the above technical solution, the structure of the arc-shaped limiting component can effectively improve the limiting and squeezing effect of the device on the side of the top opening of the test tube, thereby preventing the test tube from shaking inside the limiting hole.

[0015] Preferably, the top of the turntable is provided with a limiting groove, and an L-shaped connector is slidably connected to the inner wall of the limiting groove. The other end of the L-shaped connector is rotatably connected to the tray, and a locking member is threadedly connected to the end of the L-shaped connector away from the tray. The locking member contacts and presses against the top of the limiting groove.

[0016] By adopting the above technical solution, this solution can fix the current position of the tray by combining the tray and the L-shaped connector, thereby achieving the fixing effect after the balancing adjustment of this device is completed.

[0017] Preferably, the side of the notch is provided with symmetrical sliding grooves, the sliding groove on the side closer to the limiting groove is connected to the interior of the mutually perpendicular limiting groove, and the L-shaped connector is slidably connected to the inner wall of the sliding groove.

[0018] By adopting the above technical solution, this solution can effectively improve the sliding stability of the L-shaped connector of this device through the combination of the internally penetrating sliding groove and the limiting groove.

[0019] Preferably, the limiting holes are symmetrically arranged on both sides of the top of the tray, the spring bracket is arranged in the middle of the two limiting holes, the side of the arc-shaped limiting member is arc-shaped, and the outer end face of the arc-shaped limiting member is provided with an anti-slip layer.

[0020] By adopting the above technical solution, this solution can laterally limit the test tube through the structure of the arc-shaped limiting component, thereby avoiding high-frequency vibration between the test tube and the inner wall of the limiting hole.

[0021] Preferably, the top of the housing is provided with a rotating bracket, the rotating bracket is rotatably mounted with a protective cover, the protective cover is a transparent protective cover, and the bottom of the protective cover is provided with a sealing element, which contacts and presses against the top of the housing.

[0036] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0037] Example 1

[0038] like Figures 1-5As shown, in order to solve the existing problems, this utility model discloses a centrifuge device for preparing pharmaceutical intermediates, including a shell 1. The shell 1 has an inclined surface on its side, a display screen 2 on the inclined surface, and several equally spaced control buttons 3 on the inclined surface. A central control module is provided inside the shell 1. The central control module is communicatively connected to the display screen 2, and the control buttons 3 are controlled by the central control module. A motor is provided inside the shell 1, and the central control module is controlled by the motor. A rotating groove 5 is provided on the top of the shell 1. A centrifugal component 6 is connected to the output end of the motor and is disposed inside the rotating groove 5.

[0039] The centrifugal component 6 includes a turntable 601 connected to the output end of the motor. The outer arc surface of the turntable 601 is provided with a notch, and the inner wall of the notch is provided with a sliding groove 603. The top of the turntable 601 is provided with a number of scale lines 602 distributed in a circle. The number of scale lines 602 is the same as the number of notches, and the scale lines 602 are located on the top side of the notch.

[0040] The inner wall of the sliding groove 603 is slidably connected to a sliding column 605, and the other end of the sliding column 605 is connected to a tray 606. The top of the tray 606 is provided with a limiting hole 607.

[0041] The top of the tray 606 is connected to a spring bracket 608, and springs 609 are symmetrically arranged on both sides of the spring bracket 608. The other end of the spring 609 is connected to a sliding member 610. The bottom of the sliding member 610 is slidably connected to the tray 606. An arc-shaped limiting member 611 is connected to the side of the sliding member 610 away from the spring 609. The arc-shaped limiting member 611 faces the limiting hole 607.

[0042] The turntable 601 has a limiting groove 604 at its top. An L-shaped connector 613 is slidably connected to the inner wall of the limiting groove 604. The other end of the L-shaped connector 613 is rotatably connected to the tray 606. A locking member 612 is threadedly connected to the end of the L-shaped connector 613 away from the tray 606. The locking member 612 contacts and presses against the top of the limiting groove 604.

[0043] The specific working principle is as follows: This device can effectively improve the stability of centrifugal processing for pharmaceutical applications. Compared with traditional devices, this device is easier to balance during centrifugal processing, thereby ensuring the stable rotation of the high-speed rotating turntable 601.

[0044] When this device is in use, the display screen 2 and control buttons 3 on the side of the housing 1 enable easy operation and control. After adding the pharmaceutical raw materials, the test tubes are placed inside the limiting holes 607 in the tray 606. The elastic sliding member 610 enables the device to provide lateral support, thereby reducing the risk of collision between the test tubes and the inner wall of the limiting holes 607. After installing the pharmaceutical samples at the diagonal corners of the turntable 601, the position of the tray 606 is adjusted according to the proportion of different weights of pharmaceuticals. The scale line 602 ensures the accuracy of the sliding of the tray 606. The proportion is that the weight ratio of pharmaceutical A to pharmaceutical B is inversely proportional to the distance from the tray 606 containing pharmaceutical A to the center of the turntable 601 and the distance from the tray 606 containing pharmaceutical B to the center of the turntable 601. This ensures that the centrifugal force is the same for different weights. Rotating the locking member 612 fixes the current position of the tray 606, preventing deviations in the position of the tray 606 due to centrifugal rotation.

[0045] At this time, the motor drives the turntable 601 to rotate at high speed, thereby achieving the centrifugal effect of this device.

[0046] Example 2

[0047] like Figures 1-5 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the first embodiment above, the centrifuge device for preparing pharmaceutical intermediates further includes: a symmetrical sliding groove 603 is provided on the side of the notch, the sliding groove 603 near the limiting groove 604 communicates with the limiting groove 604 which is perpendicular to each other, and the L-shaped connector 613 is slidably connected to the inner wall of the sliding groove 603.

[0048] The limiting holes 607 are symmetrically arranged on both sides of the top of the tray 606, the spring bracket 608 is arranged in the middle of the two limiting holes 607, the side of the arc-shaped limiting member 611 is arc-shaped, and the outer end face of the arc-shaped limiting member 611 is provided with an anti-slip layer.

[0049] The top of the housing 1 is provided with a rotating bracket, and a protective cover 4 is rotatably mounted on the rotating bracket. The protective cover 4 is a transparent protective cover, and a sealing element is provided at the bottom of the protective cover 4. The sealing element contacts and presses against the top of the housing 1.

[0050] The specific working principle is as follows: the structure of the protective cover 4 can prevent the external environment from affecting the turntable 601 during the high-speed rotation of the turntable 601. At the same time, the transparent protective cover 4 can make it easy for the staff to observe the device during operation, so as to make it easy to judge whether the centrifugation is sufficient.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
