Description

Technical Field

[0001] This utility model relates to the field of biomaterial separation technology, specifically to a biomaterial separation device. Background Technology

[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a mixture of liquid and solid particles or liquid and liquid. Centrifuges are mainly used to separate solid particles from liquid in suspension, or to separate two immiscible liquids with different densities in emulsion. They can also be used to remove liquid from wet solids. Existing centrifuge devices mainly consist of a base plate, column, centrifuge cylinder, outer shell, top cover and motor.

[0003] According to Chinese Patent CN202322636580.0, this utility model provides an adjustable centrifuge device, relating to the technical field of adjustable centrifuge devices. This utility model includes a base plate, with four columns fixedly connected to the lower surface of the base plate. A shell is fixedly connected to the upper surface of the base plate, and a motor is fixedly connected to the upper surface of the base plate. A centrifuge cylinder is disposed inside the shell, and a water outlet pipe is fixedly connected to the lower surface of the base plate, communicating with the shell. A top cover is provided on the shell, and a turntable is rotatably connected to the inner wall of the shell. An installation structure is provided inside the shell, mainly composed of cross grooves formed on the turntable. A cross block is fixedly connected to the bottom of the centrifuge cylinder, and the cross grooves are sized to match the cross block. This utility model solves the problem that replacing centrifuge cylinders is very cumbersome because existing centrifuge devices fix the centrifuge cylinders through threaded connections or welding.

[0004] Some existing biomaterial separation devices are fixed by clips during use, which makes disassembly convenient, but the fixation may be unstable during use. In addition, some devices are fixed by simple bolts, which may loosen after a period of time.

[0005] Therefore, a biomaterial separation device is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this paper addresses the problem that some existing biomaterial separation devices are fixed by clips during use. Although this allows for easy disassembly, it can lead to unstable fixation during use. In addition, some devices are fixed with simple bolts, which can loosen after a period of time.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The biological material separation device of this utility model includes a biological material separation component, a protective component is installed on the outside of the biological material separation component, and a support component is installed at the bottom of the protective component; the biological material separation component includes a shell, a motor is installed inside the shell, a second gear is fixedly connected to the top of the motor, and a first gear is meshed on the side of the second gear, a support rod is fixedly connected inside the first gear, a bearing is fixedly connected to the bottom of the support rod, a turntable is fixedly connected to the top of the support rod, a centrifuge tank is fixedly connected to the top of the turntable, a bolt is threaded inside the turntable, a first spring is provided outside the bolt, and a nut is threaded on the outer wall of the bolt.

[0008] Preferably, the motor forms a transmission structure through a second gear, a first gear, and a support rod, and the second gear and the first gear mesh with each other.

[0009] Preferably, the centrifuge bucket is detachable from the turntable via bolts and nuts, and the bolts are elastically connected to the centrifuge bucket via a first spring.

[0010] Preferably, the protective component includes a protective box, with a liquid outlet pipe fixedly connected to the bottom of the protective box, a hinge fixedly connected to the top of the protective box, a cabinet door fixedly connected to the side of the hinge, a buckle fixedly connected to the end of the cabinet door, an insert rod fixedly connected inside the buckle, a second spring fixedly connected to the bottom end of the insert rod, and a metal shell fixedly connected to the outside of the second spring.

[0011] Preferably, the liquid outlet pipe and the protective box form a connected structure, and the cabinet door forms a rotating structure with the protective box via a hinge. Furthermore, the cabinet door and the buckle are integrated, the buckle and the insertion rod form an engaging structure, and the insertion rod forms an elastic structure with the metal shell via a second spring.

[0012] Preferably, the support assembly includes a support plate, the bottom of which is fixedly connected to an internal threaded rod, and the internal threaded rod is threadedly connected to a threaded rod, and the bottom of the threaded rod is connected to a base plate.

[0013] Preferably, the base plate forms a lifting structure through a threaded rod and an inner threaded rod, and the threaded rod and the inner threaded rod form a threaded structure.

[0014] The advantages of this utility model are:

[0015] 1. This utility model, by incorporating a biological material separation component and employing a design with different gear ratios, allows for convenient adjustment of the centrifuge drum's rotation speed. Since the second gear has fewer teeth than the first gear, the high-speed rotation of the motor can be reduced and transmitted to the support rod, thereby driving the centrifuge drum. This is suitable for situations where high speed is not required but a large torque is needed for startup. Conversely, if high-speed rotation of the centrifuge drum is required, a gear combination with the opposite gear ratio can be selected to meet the diverse speed requirements of different biological material separation methods.

[0016] 2. This utility model, by incorporating protective components and a hinged cabinet door, allows operators to easily open and close the protective box. When placing or removing biological material samples, or installing or maintaining centrifuge containers and internal components, the rotating cabinet door eliminates the need for additional complex operating mechanisms; simply pushing or pulling the door improves operational efficiency, reduces operational difficulty, and facilitates daily use and maintenance. The engagement of the latch and the insert ensures the cabinet door is tightly closed, preventing external dust, microorganisms, and other contaminants from entering the protective box during biological material separation and affecting sample purity and separation results. It also prevents potentially harmful biological materials from leaking into the external environment, causing pollution or safety hazards, thus ensuring the biological material separation process takes place in a relatively closed, clean, and safe environment.

[0017] 3. This utility model, by incorporating a support component, addresses the varying heights of laboratory desktops or work platforms. This lifting structure allows the biological material separation device to easily adapt to different site conditions. Whether on a high experimental platform or a low operating platform, the device can be adjusted to a suitable height, ensuring stable placement and normal operation. This increases the device's versatility and adaptability. The threaded structure has a self-locking characteristic; once the device is adjusted to the required height by rotating the threaded rod, it maintains height stability without external force causing reverse rotation. The height will not change due to the device's own weight or slight external interference. This allows for precise maintenance of the device at the set height during biological material separation operations, ensuring consistent experimental conditions and improving the accuracy and repeatability of separation results.

[0028] Please see Figures 1 to 5The biomaterial separation device shown includes a biomaterial separation component 1, a protective component 2 installed on the outside of the biomaterial separation component 1, and a support component 3 installed at the bottom of the protective component 2. The biomaterial separation component 1 includes a housing 101, a motor 105 installed inside the housing 101, a second gear 106 fixedly connected to the top of the motor 105, and a first gear 102 meshing with the side of the second gear 106.

A centrifuge tank 107 is fixedly connected to the top of the turntable 111. A bolt 108 is threaded inside the turntable 111, and a first spring 109 is provided on the outside of the bolt 108. A nut 110 is threaded on the outer wall of the bolt 108. The motor 105 forms a transmission structure with the support rod 104 through the second gear 106, the first gear 102, and the second gear 106 and the first gear 102 mesh with each other. The centrifuge tank 107 forms a detachable structure with the turntable 111 through the bolt 108 and the nut 110. The bolt 108 forms an elastic structure with the centrifuge tank 107 through the first spring 109.

[0029] Please see Figure 4 The protective component 2 of the biological material separation device includes a protective box 201. A liquid outlet pipe 208 is fixedly connected to the bottom of the protective box 201, and a hinge 202 is fixedly connected to the top of the protective box 201. A cabinet door 203 is fixedly connected to the side of the hinge 202. A buckle 204 is fixedly connected to the end of the cabinet door 203. An insertion rod 207 is fixedly connected inside the buckle 204. A second spring 206 is fixedly connected to the bottom end of the insertion rod 207. A metal shell 205 is fixedly connected to the outside of the second spring 206. The liquid outlet pipe 208 and the protective box 201 form a communication structure. The cabinet door 203 and the protective box 201 form a rotating structure through the hinge 202. The cabinet door 203 and the buckle 204 are integrated. The buckle 204 and the insertion rod 207 form an engaging structure. The insertion rod 207 and the metal shell 205 form an elastic structure through the second spring 206.

[0030] Please see Figure 5 The biomaterial separation device shown includes a support component 3 comprising a base plate 301, with an inner threaded rod 302 fixedly connected to the bottom of the base plate 301, and a threaded rod 303 threadedly connected inside the inner threaded rod 302, and a support plate 304 connected to the bottom of the threaded rod 303; the support plate 304 forms a lifting structure with the inner threaded rod 302 through the threaded rod 303, and the threaded rod 303 and the inner threaded rod 302 form a threaded structure.

[0031] Working Principle: First, before use, the operator adjusts the internal threaded rod 302 by rotating the threaded rod 303 in the support assembly 3 to raise or lower the base plate 301, thereby determining the appropriate height position of the biomaterial separation assembly 1 according to the actual operating environment and needs. When the motor 105 is turned on and running at high speed, power is stably transmitted from the second gear 106 through the first gear 102 to the support rod 104. The support rod 104 rotates at high speed under the support of the bottom bearing 103, thereby driving the turntable 111 and the centrifuge tank 107 to rotate at high speed. The biomaterials are subjected to a strong centrifugal force pointing towards the edge of the centrifuge tank 107. Under the influence of the difference in centrifugal force, biomaterials of different densities, sizes, or properties begin to gradually stratify and distribute in different positions within the centrifuge tank 107. The protective box 201 tightly encloses the biomaterial separation assembly 1, providing it with a comprehensive physical protective barrier, effectively preventing accidental collisions and interference with the separation process from external objects. The cabinet door 203, connected to the top of the protective box 201 via a hinge 202, is ingeniously designed. The latch 204 at its end and the insert rod 207 form a locking structure that plays a crucial role when the cabinet door 203 is closed. With the assistance of the elastic structure formed by the second spring 206 and the metal shell 205, the insert rod 207 smoothly inserts into the latch 204, ensuring the cabinet door 203 is tightly closed. This sealing structure effectively prevents dust, microorganisms, and other contaminants from entering the protective box 201 during the separation process, while also preventing leakage of internal biological materials into the external environment. This creates a safe and clean enclosed space for the separation of biological materials. The liquid outlet pipe 208, fixedly connected to the bottom of the protective box 201, forms a communication structure with the internal space of the protective box 201. During the separation of biological materials, both the waste liquid generated during centrifugation and the separated liquid components can flow naturally along the bottom of the protective box 201 to the liquid outlet pipe 208, and under the influence of gravity or external guidance, such as a connected suction device, are orderly guided to designated collection containers for subsequent processing, analysis, or disposal. This waste liquid discharge mechanism not only ensures the cleanliness of the internal environment of the protective box 201, but also facilitates the centralized management and further utilization of the separated liquid.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
