Description

Technical Field

[0001] This utility model relates to the field of pipe clamping technology, and in particular to a device for clamping flexible hoses and a tangential flow filtration system including the same. Background Technology

[0002] As a key component for the transmission of liquid or gaseous fluids, hoses are widely used in medical, chemical, energy and industrial manufacturing fields because their flexibility allows them to adapt to many complex working conditions.

[0003] For example, flexible hoses can be used in tangential flow filtration systems to transport the liquid flowing into the system. However, when the hoses in a tangential flow filtration system are long, they are prone to tangling, and may even close due to flow path closure. A closed hose not only unexpectedly stops the transport of liquid, thus interrupting the normal operation of the tangential flow filtration, but may also cause a sharp increase in internal pressure, potentially leading to safety accidents such as hose explosion or liquid leakage. Therefore, during tangential flow filtration, it is necessary to clamp and manage the hoses to ensure proper operation and prevent safety accidents.

[0004] Currently, there is no mature device on the market for clamping the hoses of tangential flow filtration systems. Therefore, there is an urgent need for a device to clamp the hoses of tangential flow filtration systems so that the hoses can be clamped and stored in an orderly manner according to actual working needs. This would prevent the hoses from getting tangled and ensure the normal operation of tangential flow filtration. At the same time, it would also avoid production safety accidents and ensure the personal safety of the workers. Utility Model Content

[0057] In the following embodiments, the tangential flow filtration system described is prior art known in the art. For example, the commercially available "Whaleintelli" tangential flow filtration system can be used, which will not be described in detail here.

[0058] Example 1

[0059] Reference Figures 1-10 In a first aspect, this utility model provides a device for clamping flexible hoses, the device comprising at least a first clamping plate 1, a second clamping plate 2, a telescopic motor 12, a mounting bracket 7, and a push-button switch 17, wherein:

[0060] like Figure 1 As shown, the second clamping plate 2 is installed at one end of the mounting bracket 7 (i.e., Figure 1 The telescopic motor 12 is installed at the other end of the mounting bracket 7 (i.e., the left end of the mounting bracket 7). Figure 1 The first clamping plate 1 is located at the right end of the mounting bracket 7 (i.e., the end of the second clamping plate 2 away from the mounting bracket 7). Figure 1 The left end of the second clamping plate 2), the output end of the telescopic motor 12 (i.e. Figure 10 The left end of the telescopic motor 12 is engaged with the first clamping plate 1 for transmission. The telescopic motor 12 is prior art known in the art and will not be described in detail here.

[0061] In this embodiment, as Figure 8 As shown, the mounting bracket 7 can be a C-shaped structure or a roughly C-shaped structure, and the bends of the C-shaped mounting bracket 7 are all right-angle structures (e.g., the structure of C-shaped steel known in the art). Therefore, the three plates in the mounting bracket 7 that make up the C-shaped structure are all straight plates.

[0062] For ease of description, mounting bracket 7 is located in Figure 8 The straight plate on the left side is named the first vertical plate, and the mounting bracket 7 is located at... Figure 8 The straight plate on the right side (i.e., the plate parallel to the first vertical plate) is named the second vertical plate, and the straight plate in the middle of the mounting bracket 7 (i.e., the plate perpendicular to the first vertical plate) is named the horizontal straight plate.

[0063] In this embodiment, as Figure 4 As shown, the second clamping plate 2 and the telescopic motor 12 are respectively mounted on the first vertical plate and the second vertical plate. The connection method between the telescopic motor 12 and the mounting frame 7, and the connection method between the second clamping plate 2 and the mounting frame 7, can both be achieved through bolt connections known in the art, and are not particularly limited here.

[0064] like Figures 1-5 As shown, the opposite ends of the first clamping plate 1 and the second clamping plate 2 (i.e. Figure 1 Both the right end of the first clamping plate 1 and the left end of the second clamping plate 2 are provided with hose clamping grooves 3, and the two hose clamping grooves 3 are set correspondingly. The hose clamping grooves 3 are adapted to the hose (not shown in the figure) and can be used to place the hose.

[0065] In this embodiment, the first clamping plate 1 can be engaged or disengaged from the second clamping plate 2 under the power of the telescopic motor 12's telescopic end, thereby clamping and removing the hose. The shape of the hose clamping groove 3's cross-section is not particularly limited; it can be... Figure 1 The square structure shown can also be a circular structure, etc.

[0066] In this embodiment, as Figure 1 As shown, when the first clamping plate 1 and the second clamping plate 2 are attached, the two hose clamping through grooves 3 opened on the first clamping plate 1 and the second clamping plate 2 will merge to form a through hole-like structure, thereby clamping the hose.

[0067] Furthermore, if the size of a hose clamping groove 3 is sufficient to accommodate the hose, then the hose clamping groove 3 can also be separately opened on one end opposite to the first clamping plate 1 or the second clamping plate 2.

[0068] like Figure 1 As shown, this device is equipped with a push-button switch 17, which is electrically connected to the telescopic motor 12 for starting the telescopic motor 12. That is, the push-button switch 17 can control the opening and closing of the telescopic motor 12. The push-button switch 17 is prior art known in the art and will not be described in detail here.

[0069] In this embodiment, the electrical connection between the push-button switch 17 and the telescopic motor 12 can be made by connecting them through wires known in the art, and is not particularly limited here.

[0070] In this embodiment, when the button switch 17 is pressed once, the output end (i.e., the telescopic end) of the telescopic motor 12 will drive the first clamping plate 1 to move away from the second clamping plate 2, and stop after moving a certain distance. Thus, the hose can be placed on the hose clamping groove 3 between the first clamping plate 1 and the second clamping plate 2. After placement, the button switch 17 is pressed again. At this time, the output end of the telescopic motor 12 will drive the first clamping plate 1 to move closer to the second clamping plate 2, and stop when the first clamping plate 1 and the second clamping plate 2 are in contact. Thus, the hose can be clamped on the hose clamping groove 3.

[0071] In this embodiment, as Figure 2 As shown, a certain distance can exist between the second clamping plate 2 and the mounting bracket 7 (i.e., between the second clamping plate 2 and the first vertical plate). Since this device can be installed in a tangential flow filtration system, such as the commercially available "Whaleintelli" tangential flow filtration system, therefore, as... Figure 7 As shown, threaded holes can be pre-drilled at the four corners of the first vertical plate, allowing it to be bolted into the tangential flow filtration system. The connection point between this device and the tangential flow filtration system can be located within the distance between the second clamping plate 2 and the first vertical plate.

[0072] For example, the commercially available "Whaleintelli" tangential flow filtration system includes a housing, and the device can be bolted onto the housing through the threaded holes pre-drilled on the first vertical plate. At this time, the shell wall will be located within the distance between the second clamping plate 2 and the first vertical plate, that is, the first clamping plate 1 and the second clamping plate 2 will be located outside the housing, while other components will be located inside the housing.

[0073] According to one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the first clamping plate 1 and the second clamping plate 2 can be cuboid structures with the same cross-sectional area and volume, meaning that the first clamping plate 1 and the second clamping plate 2 can be exactly the same size. The hose clamping groove 3 has a straight or approximately straight structure along its length, meaning it can be a straight groove. Because the first clamping plate 1 and the second clamping plate 2 are exactly the same size, the overall integrity of the device can be better ensured.

[0074] According to one embodiment of the present invention, such as Figure 7 As shown, a limiting sliding rod 8 is installed on the mounting bracket 7, and the limiting sliding rod 8 is set parallel to the extension direction of the output end of the telescopic motor 12.

[0075] In this embodiment, as Figure 8 As shown, there can be two limiting sliding rods 8, which can be symmetrically arranged between the two parallel straight plates (i.e., the first vertical plate and the second vertical plate) of the C-shaped mounting bracket 7. The connection between the limiting sliding rods 8 and the mounting bracket 7 can be a threaded connection.

[0076] like Figure 6 and Figure 7 As shown, the upper limit sliding rod 8 is slidably mounted with a moving block 9, which is connected to the output end of the telescopic motor 12. The connection between the moving block 9 and the telescopic motor 12 can be fixed by bolt connection.

[0077] like Figure 6 As shown, a transmission rod 6 is installed at the end of the movable block 9 away from the telescopic motor 12, and the end of the transmission rod 6 away from the movable block 9 is connected to the first clamping plate 1. The connection between the transmission rod 6 and the first clamping plate 1 can be a fixed connection via bolts. That is, the output end of the telescopic motor 12 will engage with the first clamping plate 1 through the limiting sliding rod 8, the movable block 9, and the transmission rod 6.

[0078] In this embodiment, as Figure 6As shown, there can be two transmission rods 6, which are symmetrically arranged at the end of the moving block 9 away from the telescopic motor 12. The transmission rods 6 and the moving block 9 can be fixedly connected by bolts.

[0079] In this embodiment, as Figure 4 and Figure 6 As shown, the transmission rod 6 can be a cylindrical structure. Two sliding through holes can be formed on the first vertical plate, each corresponding to one of the two transmission rods 6. The two transmission rods 6 can extend into the two sliding through holes and slide in cooperation with them.

[0080] Specifically, in this embodiment, such as Figure 7 and Figure 9 As shown, a sliding through hole 11 is provided on the movable block 9 along the length direction of the limiting sliding rod 8. The sliding through hole 11 is correspondingly provided with and adapted to the limiting sliding rod 8. The limiting sliding rod 8 is slidably engaged within the sliding through hole 11, that is, the side wall of the limiting sliding rod 8 will slide and engage with the inner wall of the sliding through hole 11. At this time, the limiting sliding rod 8 will be slidably connected to the movable block 9 through the sliding through hole 11.

[0081] In this embodiment, as Figure 7 As shown, the limiting sliding rod 8 can be a multi-prism structure, preferably a hexagonal prism structure. Since the sliding through hole 11 is adapted to the limiting sliding rod 8, the sliding through hole 11 is also preferably a hexagonal prism through hole.

[0082] When it is necessary to separate the first clamping plate 1 and the second clamping plate 2, that is, when the hose needs to be placed into the hose clamping groove 3, the operator can start the telescopic motor 12 through the button switch 17. At this time, the output end of the telescopic motor 12 will drive the moving block 9 to slide on the limit sliding rod 8 (i.e., towards the limit sliding rod 8). Figure 7 (Moving to the left in the middle), the moving block 9 will simultaneously drive the transmission rod 6 towards Figure 7 Move the device to the left, thereby pushing the first clamping plate 1 and separating the first clamping plate 1 and the second clamping plate 2. After placement, reverse the above steps to clamp the hose in the combined hose clamping groove 3.

[0083] like Figure 6 As shown, when the first clamping plate 1 and the second clamping plate 2 are in a combined state, there will be a certain distance between the moving block 9 and the straight plate (i.e., the first vertical plate) on the left side of the mounting frame 7. At this time, the right side of the moving block 9 can also be in contact with the second vertical plate, thereby ensuring that the moving block 9 moves to the left on the limiting sliding rod 8 (i.e., Figure 6 The smooth movement of the left side of the middle ensures the smooth separation of the first clamping plate 1 and the second clamping plate 2.

[0084] According to one embodiment of the present invention, such as Figure 3 , Figures 6-8 As shown, a slide rail 13 is installed on the mounting bracket 7, and the slide rail 13 is arranged parallel to the limiting slide rod 8.

[0085] In this embodiment, as Figure 8 As shown, there can be two slide rails 13, which are symmetrically bolted to the bottom of the horizontal straight plate inside the mounting bracket 7.

[0086] like Figure 7 and Figure 9 As shown, a slider 10 is installed on the movable block 9, and the slider 10 slides in conjunction with the slide rail 13.

[0087] In this embodiment, since there are two slide rails 13, there can also be two sliders 10, which are sequentially limited and slidably engaged with the two slide rails 13.

[0088] In this embodiment, by setting the limiting sliding rod 8, the slider 10 and the slide rail 13, the output end of the telescopic motor 12 can be provided with limiting and guiding effects during extension and retraction, thereby ensuring the stability of the output end of the telescopic motor 12 during extension and retraction.

[0089] In this embodiment, as Figure 1 and Figure 4 As shown, the push button switch 17 is mounted on the movable block 9, and the pressing end of the push button switch 17 is equipped with a button cap connecting rod 5, which can be set parallel to the limit sliding rod 8.

[0090] In this embodiment, as Figure 9 As shown, moving block 9 is in Figure 9 A recess is provided on the right side of the component, and the push-button switch 17 is installed in this recess. The push-button switch 17 can be connected to the moving block 9 by bolts, which is not specifically limited here.

[0091] like Figures 2-8 As shown, the mounting bracket 7 (i.e., the first vertical plate), the second clamping plate 2, and the first clamping plate 1 all have through holes 18 for button cap connecting rods, and the three through holes 18 are correspondingly arranged, that is, the three through holes 18 are located on the same straight line, and the button cap connecting rod 5 is located inside the three through holes 18. For example, Figure 6 As shown, a button cap 4 is installed at the end of the button cap connecting rod 5 away from the button switch 17 (i.e., the left end of the button cap connecting rod 5).

[0092] In this embodiment, as Figure 6 As shown, the cross-section of the button cap 4 can be a T-shaped structure, which can be connected to the button cap connecting rod 5 by means of threaded connection.

[0093] In this embodiment, since the button cap connecting rod 5 and the pressing end of the button switch 17 are connected to each other, if the button switch 17 needs to be pressed, that is, if the telescopic motor 12 needs to be started, the button cap 4 only needs to be pressed. At this time, the button cap 4 drives the button cap connecting rod 5 to press the pressing end of the button switch 17, thereby realizing the start of the telescopic motor 12.

[0094] Furthermore, the button cap connecting rod through holes 18 on the mounting bracket 7 (i.e., the first vertical plate) and the second clamping plate 2 are both adapted to the button cap connecting rod 5. The button cap connecting rod 5 is slidably fitted in the button cap connecting rod through holes 18 on the mounting bracket 7 (i.e., the first vertical plate) and the second clamping plate 2. That is, at this time, the side wall of the button cap connecting rod 5 will slide with the inner wall of the button cap connecting rod through holes 18 on the first vertical plate and the second clamping plate 2, thereby ensuring the stability of the button cap connecting rod 5 when moving.

[0095] According to one embodiment of this utility model, the button cap connecting rod through hole 18 on the first clamping plate 1 is adapted to the button cap 4. The button cap 4 is located inside the button cap connecting rod through hole 18 on the first clamping plate 1 and slides in cooperation with the button cap connecting rod through hole 18 on the first clamping plate 1. That is, the inner wall of the button cap connecting rod through hole 18 on the first clamping plate 1 slides in cooperation with the side wall of the button cap 4. Wherein, as Figure 1 As shown, the end of button cap 4 furthest from button cap connecting rod 5 (i.e. Figure 1 The left end of the middle button cap 4) and the end of the first clamping plate 1 away from the second clamping plate 2 (i.e. Figure 1 The left end of the first clamping plate 1 is flush with the button cap 4, which ensures better integration between the button cap 4 and the first clamping plate 1.

[0096] During the separation of the first clamping plate 1 and the second clamping plate 2, since the button switch 17 is mounted on the moving block 9 in this embodiment, the button switch 17 will move along with the moving block 9 as the telescopic motor 12 drives the moving block 9 to move. Figure 1 For example, when it is necessary to separate the first clamping plate 1 and the second clamping plate 2, the button cap connecting rod 5 and the button cap 4 will synchronously follow the first clamping plate 1 and move towards each other. Figure 1 The button cap 4 moves to the left of the first clamping plate 1, and the distance it moves is the same. Therefore, the button cap 4 will always remain relatively stationary with respect to the first clamping plate 1, which can greatly improve the convenience for staff to press the button cap 4.

[0097] A second aspect of this invention provides a tangential flow filtration system comprising the aforementioned hose clamping device. Those skilled in the art should understand that any tangential flow filtration system using this device should be included within the protection scope of this invention.

[0098] In addition, multiple units of this device can be installed in the tangential flow filtration system and arranged according to actual working needs. This allows for the orderly arrangement of the clamped hoses and tubing, thereby reducing the total length of the hoses and tubing and the volume of liquid retention, and improving the efficiency of tangential flow filtration.

[0099] Example 2

[0100] In this embodiment, refer to Figure 11 The first clamping plate 1 and the second clamping plate 2 are L-shaped structures with the same cross-sectional area and volume, meaning that the first clamping plate 1 and the second clamping plate 2 can be exactly the same size. The hose clamping groove 3 is L-shaped or approximately L-shaped along its length.

[0101] When the hose needs to be bent, the first clamping plate 1, the second clamping plate 2, and the hose clamping groove 3, which have an L-shaped structure in this embodiment, can clamp the hose at the bend, thereby improving the firmness of the hose clamping.

[0102] Example 3

[0103] In this embodiment, refer to Figure 11 A flow sensor 14 (known in the art) can be bolted onto the inner wall of the hose clamping groove 3. When the first clamping plate 1 and the second clamping plate 2 clamp the hose in the hose clamping groove 3, the flow sensor 14 can monitor the flow rate of the fluid (e.g., the liquid in a tangential flow filtration system) in the hose.

[0104] Example 4
