Description

Technical Field

[0001] This utility model relates to the field of medicinal residue filtration connection technology, specifically a connection device that facilitates medicinal residue filtration. Background Technology

[0002] In the production processes of traditional Chinese medicine, food, and chemicals, there are often steps involved in filtering and separating mixtures of liquids and medicinal residues (or solid residues). These processes often require sequentially introducing the same material source into filtration equipment of varying precision or to different subsequent processing stages; for example, first coarse filtration, then fine filtration, and finally the filtrate is transferred to a collection tank. This process typically involves frequent switching of pipeline connections.

[0003] Currently, the conventional method for pipeline switching is manual operation, where workers manually disassemble the current pipeline and then connect and tighten the moving pipeline to the target interface. This traditional method has many drawbacks: First, the process of manually disassembling, connecting, and tightening flanges or clamps is cumbersome, time-consuming, and labor-intensive, severely restricting the improvement of production efficiency, especially in processes that require frequent switching; second, manual operation is inherently uncertain, and improper installation or uneven tightening of the sealing ring at the pipeline interface can easily lead to leakage under pressure, resulting in material loss, contamination of the production environment, and even safety issues; third, when multiple interfaces coexist, manual operation inevitably carries the risk of misconnection, which may lead to cross-contamination of filtrates of different qualities, affecting the quality stability of the final product.

[0004] Therefore, there is an urgent need in the existing technology for a connection device that can achieve fast, reliable, and automated channel switching to solve the technical problems of low efficiency, easy leakage, and easy crosstalk in traditional manual connection methods.

The connection between the second and first channels and the connection between the third and second channels are provided with baffles by pins. The connection between the second and first channels and the connection between the third and second channels are provided with second limiting grooves below.

[0007] Furthermore, a feed inlet is provided on the upper part of the shell, and a first discharge outlet, a second discharge outlet, and a third discharge outlet are provided sequentially on the lower part of the shell, with the feed inlet, the first discharge outlet, the second discharge outlet, and the third discharge outlet located above and below the second chamber.

[0008] Furthermore, a feeding pipe is provided at the feeding port, a first discharge pipe is provided at the first discharge port, a second discharge pipe is provided at the second discharge port, and a third discharge pipe is provided at the third discharge port.

[0009] Furthermore, the feeding pipe is connected to the first discharge pipe via the feed inlet, the first channel, and the first discharge outlet in sequence; the feeding pipe is connected to the second discharge pipe via the feed inlet, the second channel, the first channel, and the second discharge outlet in sequence; and the feeding pipe is connected to the third discharge pipe via the feed inlet, the third channel, the second channel, the first channel, and the third discharge outlet in sequence.

[0012] Furthermore, a heat dissipation mesh is provided on the side of the housing, and the heat dissipation mesh is connected to the first chamber. The heat dissipation mesh is located on the side of the motor and is made of aluminum alloy mesh plate.

[0013] (III) Beneficial Effects: Compared with existing technologies, this connection device, which facilitates the filtration of medicinal residues, has the following advantages: I. This utility model aligns multiple channels (first channel, second channel, and third channel) in the movable block with multiple discharge ports on the shell through precise relative movement. Since the distance between the discharge ports is equal to the distance between the channels, and the motor adopts stepper control, the positioning accuracy is high, which can ensure that the target channel is accurately connected every time it moves. Compared with the traditional manual disassembly of pipes for docking, the effect is faster and more time-saving and labor-saving.

[0014] II. This utility model, through the baffles at the connection between the second channel and the first channel and the third channel and the second channel, under the action of the first limiting groove and the second limiting groove, can block the baffles horizontally or vertically, thereby achieving an automatic flipping baffle structure under different channel fluids. It can reliably close or open the corresponding flow path, making each discharge path independent and switching smoothly, effectively avoiding flow path crosstalk. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-13 As shown, this utility model provides a technical solution: a connection device for easy filtration of medicinal residue, including a fixing plate 3. The fixing plate 3 is made of stainless steel with a thickness of 5-10mm and has mounting holes on its surface. The fixing plate 3 is fixed to the equipment bracket or base by bolts 4 (such as M8 or M10 standard bolts 4), thereby achieving stable installation of the housing 1. The housing 1 is fixed on the fixing plate 3. The interior of the housing 1 is divided into a first chamber 9 and a second chamber 10. The first chamber 9 is located on one side of the second chamber 10, and a through hole is provided between the two for the threaded cylinder 17 to pass through.

[0019] like Figure 2 As shown, a motor 15 is fixed in the first chamber 9. The motor 15 is a stepper motor. The output shaft of the motor 15 is fixed to a threaded rod 16 through a coupling. A threaded cylinder 17 is threadedly connected to the surface of the threaded rod 16. The inner diameter of the threaded cylinder 17 matches that of the threaded rod 16. The threaded cylinder 17 passes through the first chamber 9 into the second chamber 10 and through a through hole. A sealing ring 18 is embedded in the through hole. The sealing ring 18 is made of rubber and adopts an O-ring structure. The sealing ring 18 is pressed between the inner wall of the through hole of the housing 1 and the outer wall of the threaded cylinder 17 to ensure the seal between the first chamber 9 and the second chamber 10 and prevent liquid leakage.

[0020] The motor 15 controls the rotation of the threaded rod 16, which drives the threaded cylinder 17 to move horizontally (the direction of movement is parallel to the axis of the threaded rod 16). This, in turn, enables the movable block 19 to move horizontally. By moving the movable block 19, different channels can be opened and closed, thus completing the channel switching. Compared with manually tightening pipe connections to different interfaces, this method is more time-saving and labor-saving, and also avoids leakage that occurs during manual tightening.

[0021] The second chamber 10 is provided with a movable block 19, which is a rectangular block structure. One end of the movable block 19 is fixed by a threaded cylinder 17. The movable block 19 is provided with a first channel 20, a second channel 21 and a third channel 22 in sequence. The first channel 20 is a vertical channel (perpendicular to the moving direction of the movable block 19), and the second channel 21 and the third channel 22 are L-shaped channels (the horizontal section is connected to the vertical section). The second channel 21 is connected to the first channel 20, and the third channel 22 is connected to the second channel 21.

[0022] like Figure 3-5 As shown, a first limiting groove 23 is provided on the inner wall of the first channel 20 and the second channel 21. When the movable block 19 is in the first position, the feed pipe 5 is connected to the first discharge pipe 6 through the feed port 11, the first channel 20, and the first discharge port 12. At this time, the baffle 24 at the connection between the second channel 21 and the first channel 20 is in a vertical state. The bottom end of the baffle 24 is stuck in the second limiting groove 25, allowing the fluid to flow out through the first discharge pipe 6.

[0023] like Figure 6-8 As shown, when the movable block 19 moves to the second position, the feed pipe 5 connects to the second discharge pipe 7 via the feed inlet 11, the second channel 21, the first channel 20, and the second discharge outlet 13 in sequence. At this time, the baffle 24 at the connection between the third channel 22 and the second channel 21 is in a vertical state, and the bottom end of the baffle 24 is engaged in the second limiting groove 25, allowing the fluid to flow from the second channel 21 to the first channel 20. The baffle 24 at the connection between the second channel 21 and the first channel 20 is in a horizontal state, and the baffle 24 is engaged in the first limiting groove 23, closing the direct outlet of the first channel 20, and the fluid can only flow out from the second discharge outlet 13.

[0024] like Figure 9-11As shown, when the movable block 19 moves to the third position (the moving distance is equal to the distance between the second channel 21 and the third channel 22), the feed pipe 5 sequentially connects to the third discharge pipe 8 via the feed inlet 11, the third channel 22, the second channel 21, the first channel 20, and the third discharge outlet 14. At this time, the baffle 24 at the connection between the third channel 22 and the second channel 21 is in a horizontal state, and the baffle 24 is engaged in the first limiting groove 23, closing the direct inlet of the second channel 21; the baffle 24 at the connection between the second channel 21 and the first channel 20 is in a horizontal state, and the baffle 24 is engaged in the first limiting groove 23, closing the direct outlet of the first channel 20, and the fluid can only flow out from the third discharge outlet 14.

[0025] In the above process, the motor 15 drives the movable block 19 to move via the threaded rod 16 and the threaded cylinder 17, forming a separate channel. The motor 15 is connected to an external PLC controller via a wired connection. The PLC preset program controls the motor 15 to perform stepping operations (for example, using three-position control, moving the same position in each step). The stepping control method includes forward, backward, and reset, or the position accuracy is ensured by an encoder. Since the distance between the first discharge port 12, the second discharge port 13, and the third discharge port 14 is equal to the distance between the first channel 20, the second channel 21, and the third channel 22, the movable block 19 will align with the channel when it moves the same distance, realizing the connection between different pipes.

[0026] Specifically, a heat dissipation mesh 2 is provided on the side of the housing 1. The heat dissipation mesh 2 is an aluminum alloy mesh plate. The heat dissipation mesh 2 is connected to the first chamber 9 and is located on the side of the motor 15. The heat dissipation mesh 2 can dissipate heat from the motor 15 in the first chamber 9, prevent the motor 15 from overheating, and extend its service life.
