Description

Technical Field

[0001] This utility model relates to the field of bovine serum filtration, and more specifically, to a multi-stage bovine serum filtration device. Background Technology

[0002] Serum is a complex mixture formed by removing fibrin from blood plasma. It contains various plasma proteins, polypeptides, fats, carbohydrates, growth factors, hormones, and inorganic substances, which maintain a physiological balance in promoting or inhibiting cell growth. Bovine serum is the most widely used natural culture medium for cell culture, containing abundant nutrients essential for cell growth. It is commonly used for the in vitro culture of animal cells and plays a vital role.

[0003] In the prior art, Chinese utility model patent with publication number CN222738668U discloses a multi-stage filtration device for bovine serum. This device uses a reciprocating rotating drum and internal filter components set in a housing to move the bovine serum during filtration. The shear force of the liquid slows down the deposition of particles on the filter screen surface, thereby reducing the risk of clogging to a certain extent. However, in actual use, the shear force generated by the horizontal reciprocating rotation mainly acts to prevent impurities from being evenly covered in the plane of the filter screen. But it is difficult to generate effective peeling force for particles and sticky substances that are embedded in the filter screen pores, which can easily form stubborn blockage in the axial direction of the filter pores. Moreover, after the filter element is disassembled, additional backwashing or other means are still required to clean the residue deep in the pores. In view of this, we propose a multi-stage filtration device for bovine serum to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenience in using current multi-stage bovine serum filtration devices.

[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a multi-stage bovine serum filtration device, comprising a housing, a rotating cylinder inside the housing, at least one mounting ring inside the rotating cylinder, a fixing plate inside the mounting ring, an annular filter plate between the fixing plate and the mounting ring, the annular filter plate being embedded inside the mounting ring, two assembly rods outside the mounting ring, at least one sliding groove on the surface of each assembly rod, the mounting ring being slidably connected inside the sliding groove, a buffer assembly inside the sliding groove, a connecting rod rotatably sleeved inside the fixing plate, and a transmission assembly outside the connecting rod.

[0006] As a preferred technical solution of this application, the buffer assembly includes a guide rod, which is fixedly connected inside the sliding groove. The mounting ring is slidably sleeved on the outside of the guide rod. Two buffer springs are movably sleeved on the outside of the guide rod. The near ends of the two buffer springs are fixedly connected to the mounting ring, and the opposite ends of the two buffer springs are fixedly connected to the inner walls of the two sides of the sliding groove, respectively.

[0007] As a preferred technical solution of this application, a sealing baffle is fixedly connected to the surface of the mounting ring, and the outer arc surface of the sealing baffle fits against the assembly rod.

[0008] As a preferred technical solution of this application, the transmission assembly includes a fixed rod, which is fixedly connected to a connecting rod. A fixed ring is fixedly connected to the outside of the fixed rod. An arc-shaped protrusion is fixedly connected to the upper surface of the fixed ring. A rolling ball is movably embedded in the lower surface of the mounting ring. The mounting ring contacts the arc-shaped protrusion and the fixed ring through the rolling ball embedded in the bottom.

[0009] As a preferred technical solution of this application, a crossbar is fixedly connected to the bottom inner wall of the box, a rectangular through groove is opened inside the crossbar, and a rectangular block is fixedly connected to the bottom of the connecting rod, the rectangular block and the rectangular through groove being compatible.

[0010] As a preferred technical solution of this application, a support frame is fixedly connected to the bottom inner wall of the box, and a support ring is rotatably sleeved at the bottom discharge end of the rotating drum, and the support ring and the support frame are fixedly connected.

[0011] As a preferred technical solution of this application, the inner wall of the rotating drum is provided with two assembly vertical grooves, and the two assembly rods are slidably connected inside the two assembly vertical grooves respectively, and the upper ends of the two assembly rods are fixedly connected with lifting rings.

[0012] As a preferred technical solution of this application, a toothed ring is fixedly sleeved on the outside of the rotating drum, and a driving device is provided on the inner wall of the box, wherein the gear and the toothed ring in the driving device are meshed and connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. Through the cooperation of structures such as fixed rods, fixed rings, arc-shaped protrusions, rolling balls, rectangular blocks, and rectangular grooves, during the rotation of the rotating drum, the stationary arc-shaped protrusions contact with the rolling balls, driving the mounting ring to periodically rise and fall in the vertical direction. This achieves continuous and automatic axial vibration of the annular filter plate during the filtration process. This vertical vibration can generate an effective axial peeling force on particles and sticky substances embedded in the filter screen pores, significantly reducing filter pore clogging and improving filtration efficiency and continuity.

[0016] 2. The cooperation between the guide rod and the buffer spring provides stable guidance and elastic reset for the vertical reciprocating motion of the mounting ring, ensuring the verticality and stability of the vibration trajectory. The buffer spring provides auxiliary restoring force when the mounting ring falls back, forming a gentle and regular vibration rhythm, which not only enhances the cleaning effect, but also avoids damage to the filter structure that may be caused by rigid impact, thus extending the service life of the filter.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A multi-stage bovine serum filtration device includes a housing 1. Inside the housing 1 is a rotating drum 2. Inside the rotating drum 2 is at least one mounting ring 3 for support. Since multiple mounting rings 3 have the same structure, the following description focuses on the structure of one mounting ring 3. Inside the mounting ring 3 is a fixing plate 4 for connection. Between the fixing plate 4 and the mounting ring 3 is an annular filter plate 5 for multi-stage filtration of bovine serum, and the annular filter plate 5 is embedded inside the mounting ring 3. Two sliding mounting rods 6 are provided on the outside of the mounting ring 3. At least one sliding groove 7 is formed on the surface of the mounting rod 6. The number of sliding grooves 7 matches the number of mounting rings 3. The mounting ring 3 is slidably connected inside the sliding groove 7. A buffer assembly is provided inside the sliding groove 7. A connecting rod 14 is rotatably sleeved inside the fixing plate 4, and a transmission assembly is provided outside the connecting rod 14.

[0031] Among them, the connecting rod 14 rotates through each fixed plate 4 sequentially from the uppermost fixed plate 4.

[0032] In the above embodiments, a sealing ring is also provided on the outer arc surface of the mounting ring 3 to ensure the sealing between the mounting ring 3 and the rotating cylinder 2. Since this is a conventional technical means in the field, it will not be described in detail here.

[0033] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the buffer assembly includes a guide rod 8 for limiting the movement trajectory of the structure. The guide rod 8 is fixedly connected inside the sliding groove 7. The mounting ring 3 is slidably sleeved on the outside of the guide rod 8. Two buffer springs 9 are movably sleeved on the outside of the guide rod 8 for buffering. The near ends of the two buffer springs 9 are fixedly connected to the mounting ring 3, and the opposite ends of the two buffer springs 9 are fixedly connected to the inner walls of the two sides of the sliding groove 7, respectively. The reciprocating movement of the mounting ring 3 in the vertical direction can drive the two buffer springs 9 to produce corresponding deformation. When the mounting ring 3 moves upward, the buffer springs 9 are compressed and stored. When the mounting ring 3 moves downward, it moves downward under the combined action of its own weight and the restoring force released by the buffer springs 9. This cycle is repeated, realizing the reciprocating lifting and falling of the mounting ring 3 mainly in the vertical direction. The key is that the guide rod 8 slides through the mounting ring 3, thus providing rigid vertical guidance for the up and down movement of the mounting ring 3, effectively constraining the swing or swaying of the mounting ring 3 in the horizontal direction.

[0034] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a sealing baffle 13 for shielding the sliding groove 7 is fixedly connected to the surface of the mounting ring 3. The outer arc surface of the sealing baffle 13 fits against the mounting rod 6. With the help of the sealing baffle 13, impurities are effectively prevented from entering the sliding groove 7, thereby further improving the smoothness of the mounting ring 3 when it is raised and lowered.

[0035] Example 2

[0036] The bovine serum multi-stage filtration device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the transmission assembly includes a fixed rod 15 for connection, the fixed rod 15 and the connecting rod 14 are fixedly connected, a fixed ring 10 is fixedly connected to the outside of the fixed rod 15, an arc-shaped protrusion 11 for moving the mounting ring 3 up and down is fixedly connected to the upper surface of the fixed ring 10, and a rolling ball 12 for reducing friction between the structures is movably embedded in the lower surface of the mounting ring 3. The mounting ring 3 contacts the arc-shaped protrusion 11 and the fixed ring 10 through the rolling ball 12 embedded in the bottom. When the mounting ring 3 contacts the high point of the arc-shaped protrusion 11 with the rolling ball 12, it will be forced to move upward. When the mounting ring 3 contacts the arc-shaped protrusion 11 with the rolling ball 12 and the surface of the mounting ring 3, the mounting ring 3 will fall back under its own weight and the action of the buffer spring 9.

[0037] In the above embodiments, the rolling ball 12 in the scheme can also be replaced by a pulley. The main purpose is to convert sliding friction into rolling friction, so that the movement is smoother. Since this is a technical means well known to those skilled in the art, it will not be described in detail here.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a crossbar 17 for support is fixedly connected to the bottom inner wall of the box 1. A rectangular through groove 18 for limiting is opened inside the crossbar 17. A rectangular block 16 for cooperating with the rectangular through groove 18 is fixedly connected to the bottom of the connecting rod 14. The rectangular block 16 and the rectangular through groove 18 are adapted to each other. When the rectangular block 16 at the bottom of the connecting rod 14 is inserted into the rectangular through groove 18, the stability of the connecting rod 14 can be guaranteed, and it is prevented from rotating with the rotating drum 2.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a support frame 19 for support is fixedly connected to the bottom inner wall of the box 1, and a support ring 20 for rotation is rotatably sleeved at the bottom discharge end of the rotating drum 2. The support ring 20 and the support frame 19 are fixedly connected. The support frame 19 provides support for the rotating drum 2, and the support ring 20 ensures the smooth rotation of the rotating drum 2 and avoids interference.

[0040] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the inner wall of the rotating drum 2 has two sliding assembly vertical grooves 24. Two assembly rods 6 are slidably connected inside the two assembly vertical grooves 24 respectively. The upper ends of the two assembly rods 6 are fixedly connected to lifting rings 23 for easy lifting by the workers. The upper surface of the lifting rings 23 is fixedly connected to a handle. With the cooperation of the lifting rings 23 and the assembly vertical grooves 24, it is easy for the workers to disassemble the assembly rods 6, the mounting rings 3, the fixing plates 4, the annular filter plates 5 and other structures for subsequent cleaning.

[0041] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a gear ring 21 for transmission is fixedly sleeved on the outside of the rotating drum 2, and a drive device 22 for providing power for the rotation of the rotating drum 2 is provided on the inner wall of the housing 1. The gear in the drive device 22 and the gear ring 21 are meshed and connected. Thus, after the motor in the drive device 22 is started by the external controller, the rotation of the rotating drum 2 can be realized by the cooperation of the gear and the gear ring 21.

[0042] In the above embodiments, the drive device 22 in this solution is the same as the prior art with publication number CN222738668U, which includes a motor, gears, a fixing frame, etc. Since it is a known technology in the field, it will not be described in detail here.

[0043] The usage process of the multi-stage bovine serum filtration device provided by this utility model is as follows:

[0044] After the motor in the drive unit 22 is started by the external controller, the rotating drum 2 can be rotated by the cooperation of the gear and the gear ring 21. At this time, under the action of the mounting vertical groove 24, the mounting ring 3, the fixing plate 4 and the annular filter plate 5 will rotate synchronously. Since the rectangular block 16 is located inside the rectangular through groove 18, the connecting rod 14 will not rotate, that is, the fixing ring 10 is in a stationary state. Later, when the mounting ring 3 contacts the high point of the arc-shaped protrusion 11 with the rolling ball 12, it will force the mounting ring 3 to move upward. When the mounting ring 3 contacts the high point of the arc-shaped protrusion 11 with the rolling ball 12, it will force the mounting ring 3 to move upward. When the protrusion 11 contacts the surface of the mounting ring 3, the mounting ring 3 will fall back under its own weight and the action of the buffer spring 9. The vertical reciprocating movement of the mounting ring 3 can drive the two buffer springs 9 to produce corresponding deformation. When the mounting ring 3 moves upward, the buffer spring 9 is compressed and stores energy. When the mounting ring 3 moves downward, it moves downward under the combined action of its own weight and the restoring force released by the buffer spring 9. This cycle is repeated, realizing the reciprocating lifting and falling of the mounting ring 3 mainly in the vertical direction, thereby realizing the small amplitude vibration of the annular filter plate 5.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments.
