[0002] Veterinary drugs refer to medicines used for animal diagnosis, treatment, prevention and treatment. There are many types of veterinary drugs, and injection is one of them. It generally uses original powder particles, APIs or freeze-dried substances as raw materials, and is prepared into liquid preparations with a certain volume and quality through stirring, mixing, dissolving, and blending processes. In order to ensure the quality and stability of the preparation, centrifugal equipment is needed.

[0003] At present, when veterinary drug injections are centrifuged, a motor is used to drive the centrifuge cylinder to rotate at high speed to separate components of different densities. However, since the motor of some centrifugal equipment is directly fixed to the centrifuge cylinder, workers are required to constantly change the position of their arms when cleaning the centrifuge cylinder after the operation. During deep cleaning, the workers' arms will become sore, which is not conducive to the normal cleaning operation. In addition, centrifuge cylinders of different specifications are required to separate different milliliters of injections, but since the motor and the centrifuge cylinder are fixed, only other types of separation equipment can be replaced. This will increase the number of equipment used and resource consumption.

Example 1

[0036] Reference Figure 1-6 , which is the first embodiment of the utility model, provides a centrifugal device for preparing veterinary drug injections, the centrifugal device for preparing veterinary drug injections comprises a carrying plate 1, a collecting cylinder 2 mounted on the top of the carrying plate 1, a surface of the collecting cylinder 2 is provided with a circular array of holes for separation, a centrifugal cylinder 3 mounted inside the collecting cylinder 2, a connecting rod 4 fixed to the bottom of the collecting cylinder 2, a motor 5 mounted at the bottom of the carrying plate 1, a bottom plate is mounted at the bottom of the motor 5, which is fixedly connected to the bottom of the carrying plate 1, and can facilitate the installation of the motor 5, a connecting piece 6 is mounted at the bottom of the carrying plate 1, and a flow guide piece 8 is mounted inside the collecting cylinder 2;

[0037] The connecting member 6 includes a rotating rod 61 fixed to the output end of the motor 5, an L-shaped rod 62 is fixedly connected to the outer surface of the rotating rod 61, a first connecting ring 63 and a second connecting ring 64 are fixedly connected to the outer surface of the rotating rod 61 and one end away from the L-shaped rod 62, the second connecting ring 64 is located outside the first connecting ring 63, and the first connecting ring 63 and the second connecting ring 64 are provided with thread grooves inside;

[0038] The connecting rod 4 passes through the collecting cylinder 2 and the supporting plate 1, and extends to the inside of the rotating rod 61, and is movably connected thereto. The inside of the L-shaped rod 62 is movably connected with a plug 65, and the plug 65 passes through the L-shaped rod 62, the rotating rod 61 and the connecting rod 4, and extends to the inside of the first connecting ring 63 and the second connecting ring 64, which can facilitate the fixing and removal of the connecting rod 4, thereby achieving the purpose of disassembling the centrifugal cylinder 3, and further facilitating the cleaning operation inside the centrifugal cylinder 3.

[0039] One end of the plug 65 is fixedly connected to a connecting rod 68, and the other end of the connecting rod 68 and the end away from the plug 65 is fixedly connected to a bolt 66. The bolt 66 is located inside the second connecting ring 64 and is threadedly connected thereto. The diameter of the connecting rod 68 is smaller than that of the plug 65 and the bolt 66, so the swivel 67 can be easily installed. The setting of the bolt 66 facilitates the connection between the connecting rod 4 and the swivel rod 61, and the thread direction of the bolt 66 is a forward thread.

[0040] A swivel 67 is movably sleeved on the surface of the connecting rod 68, and an external thread 69 is installed on the surface of the swivel 67. The swivel 67 is located inside the first connecting ring 63 and is threadedly connected to it through the external thread 69. The thread direction of the external thread 69 is a reverse thread, which can be fixed twice, thereby enhancing the stability of the connecting rod 4 and the swivel rod 61, preventing the bolt 66 from loosening during rotation, and the plug 65, the external thread 69 and the bolt 66 have the same diameter, which can prevent the plug 65 from getting stuck when installed, facilitating the installation and disassembly operations.

[0041] A first anti-slip strip 693 in a circular array is installed at one end of the swivel 67, and a second anti-slip strip 694 in a circular array is installed at one end of the plug 65 and away from the bolt 66. The diameter of the first anti-slip strip 693 is consistent with the diameter of the plug 65. The first anti-slip strip 693 and the second anti-slip strip 694 can increase the friction with the hand, facilitate the twisting operation, and avoid slipping, thereby saving external tools to achieve the purpose of facilitating installation and disassembly.

[0042] A positioning rod 691 is fixedly connected to one end of the swivel 67 and close to the first anti-slip strip 693, and a connecting groove 692 is opened at one end of the bolt 66 and close to the connecting rod 68. The positioning rod 691 is located inside the connecting groove 692 and is movably connected thereto. The positioning rod 691 is tubular and a rubber ball is installed at one end thereof, and the diameter of the rubber ball is larger than that of the positioning rod 691. The friction between the rubber ball and the inner wall of the connecting groove 692 is increased by the rubber ball, thereby providing a better positioning effect and preventing the swivel 67 from moving back and forth as the plug 65 is inserted.

[0043] A bearing 9 is installed at the bottom of the supporting plate 1, and the top of the rotating rod 61 is connected to the bearing 9. The rotating rod 61 is connected to the supporting plate 1 through the bearing 9. A balancing member 7 is installed inside the supporting plate 1, which can make the rotating rod 61 rotate more smoothly with the drive of the motor 5, and the connecting rod 4 also passes through the bearing 9 and extends to the inside of the rotating rod 61.

[0044] During use, the connecting rod 4 is inserted into the interior of the collecting tube 2, and the connecting rod 4 passes through the collecting tube 2 and the bearing 9, so that the bottom of the connecting rod 4 extends to the surface of the rotating rod 61, and then it is positioned by the balancing member 7, and then the plug 65 is inserted into the interior of the L-shaped rod 62, and passes through the rotating rod 61, the connecting rod 4, and the first connecting ring 63. When the bolt 66 contacts the second connecting ring 64, the plug 65 is rotated through the second anti-slip strip 694 and drives the bolt 66 to rotate, so that it is slowly connected to the second connecting ring 64, and then it can be reversed through the first anti-slip strip 693. The connecting rod 4 can be fixed by twisting the rotating ring 67 so that the external thread 69 on its surface is connected with the first connecting ring 63. Then, the motor 5 can be started to drive the connecting rod 4 and the centrifugal cylinder 3 to rotate through the rotating rod 61 to start the separation operation. When cleaning the centrifugal cylinder 3, the connecting rod 4 and the rotating rod 61 can be disconnected by reverse operation. Then, the centrifugal cylinder 3 can be removed and cleaned, so that the deep cleaning operation of the centrifugal cylinder 3 can be facilitated, avoiding the need for the arm to constantly adjust the appropriate position, thereby prolonging the service life of the centrifugal cylinder 3.

[0045] In addition, by disassembling the centrifugal cylinder 3, a centrifugal cylinder 3 of different specifications can be replaced. The replacement operation can be completed by simply inserting the connecting rod 4 into the interior of the collecting cylinder 2 and positioning it through the connecting piece 6 and the balancing piece 7. This method is simple to operate and avoids the problem of energy consumption. Example 2

[0046] Reference Figure 1-7 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0047] The balancing member 7 includes a bidirectional screw 72 rotatably connected to the inside of the supporting plate 1, one end of the bidirectional screw 72 is fixedly connected to a rotating shaft 71, one end of the rotating shaft 71 extends to the outside of the supporting plate 1, and an end of the supporting plate 1 inside and away from the bidirectional screw 72 is fixedly connected to a sliding rod 73, and the surfaces of the bidirectional screw 72 and the sliding rod 73 are both installed with a first sliding plate 74 and a second sliding plate 741, the first sliding plate 74, the second sliding plate 741 are threadedly connected to the bidirectional screw 72, and are movably sleeved with the sliding rod 73.

[0048] The inner side of the first sliding plate 74 is fixedly connected with an insert block 75, and the inner side of the second sliding plate 741 is provided with a groove 76. The insert block 75 is located on the inner side of the groove 76 and is movably connected thereto. The inner sides of the first sliding plate 74 and the second sliding plate 741 are fixedly connected with a limiting block 77. The first sliding plate 74, the second sliding plate 741 and the limiting block 77 are all arranged in a semi-arc shape. A limiting groove 78 is provided on the surface of the connecting rod 4. Two groups of limiting blocks 77 are located inside the limiting groove 78 and are movably connected thereto, which can limit the connecting rod 4. There are two groups of limiting grooves 78 to ensure its stability and prevent it from being offset during rotation. The first sliding plate 74 and the second sliding plate 741 can form a circle and wrap the connecting rod 4.

[0049] The guide member 8 includes an inclined plate 81 installed inside the collecting cylinder 2, a guide groove 82 is opened on the surface of the inclined plate 81, one end of the inclined plate 81 is fixedly connected to a receiving groove 84, one end of the receiving groove 84 is installed with a pipe 83, the pipe 83 extends to the outside of the collecting cylinder 2, and a valve is installed on the top of the collecting cylinder 2, a collection box can be placed at the bottom of the pipe 83, and the supernatant after diversion can be conveniently collected, the guide grooves 82 are arranged in multiple groups, and are all inclined, and they converge at an intersection, which is convenient for collecting the supernatant, the connecting rod 4 also passes through the inclined plate 81, and the bottom of the centrifugal cylinder 3 is higher than the top of the inclined plate 81, which can prevent sticking.

[0050] When the connecting rod 4 passes through the collecting tube 2 and extends to the inside of the rotating rod 61, the rotating shaft 71 is directly rotated to drive the bidirectional screw 72 to rotate, so that the first sliding plate 74 and the second sliding plate 741 can be driven to approach each other until the insert block 75 is completely immersed in the inside of the groove 76, and at the same time, the two sets of limit blocks 77 will slowly move toward the inside of the limit groove 78. When the limit blocks 77 are completely immersed in the inside of the limit groove 78, they will form a complete ring shape, so that the connecting rod 4 can be clamped, and the connecting rod 4 can be kept stable during rotation;

[0051] Since the centrifugal cylinder 3 itself has weight, and when separating, the injection needs to be poured into the inside, which will increase its weight. As the volume of the centrifugal cylinder 3 increases, that is, the centrifugal cylinder 3 of different specifications is replaced, its weight will also increase. The setting of the balance member 7 can provide a stabilizing force for the connecting rod 4 to prevent it from deflecting when rotating.

[0052] During the separation process, the supernatant will flow into the interior of the collecting cylinder 2 through the holes on the surface of the centrifugal cylinder 3. The supernatant can be collected into the interior of the receiving tank 84 by the arrangement of the inclined plate 81 and the guide groove 82, and can be collected through the pipe 83, thereby achieving the purpose of collecting the supernatant.

[0053] The remaining structures are the same as those of Example 1.

[0054] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
