Description

Technical Field

[0001] This utility model relates to the technical field of separation and extraction, and in particular to a feeding device for an extract purification equipment. Background Technology

[0002] In industries such as chemical, pharmaceutical, and plant extraction, precise material feeding is crucial for ensuring the quality and efficiency of subsequent purification and reaction processes. Existing feeding devices are multifunctional and lack specific features, resulting in the following shortcomings: First, most feeding devices lack high-precision real-time flow control mechanisms, making it impossible to accurately meter and quantitatively control the material entering the purification equipment, leading to poor process stability. Second, the connection between the feeding pipe and the external feed pipe usually relies on simple threads or flanges, which are prone to loosening and leakage under long-term use or pressure fluctuations, causing not only material loss but also potential safety hazards. Furthermore, traditional feeding pipes have fixed outlet sizes, making it difficult to adapt to the feed inlets of different purification equipment models, resulting in insufficient flexibility.

[0003] For example, Chinese utility model patent CN216062830U discloses a feeding device for extracting and purifying skin-whitening factors. This device primarily addresses the issues of filtering and mixing impurities in the raw materials by incorporating a filter screen, pusher plate, and stirring mechanism. However, this device does not address precise control of material flow rate, nor does it improve the sealing reliability and interface compatibility of the pipeline connections. Therefore, developing a feeding device capable of achieving precise flow control, reliable sealing, and strong adaptability is of significant practical importance. Utility Model Content

[0004] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a feeding device for an extract purification equipment. This device can achieve precise control of the feed flow rate and quantitative feeding, while also having excellent connection sealing and equipment interface adaptability.

[0005] The objective of this utility model is achieved through the following technical solution: A feeding device for an extract purification apparatus includes a feed pipe, a flow control mechanism, a guide pipe, a connecting valve, a fastening connection structure, and a flow meter. The flow control mechanism is mounted on the feed pipe, with one end of the guide pipe connected to its side. The other end of the guide pipe is connected to the connecting valve. The fastening connection structure is located at the connection between the guide pipe and the connecting valve. The flow meter is mounted on the guide pipe between the fastening connection structure and the flow control mechanism.

[0006] Furthermore, the feed tube includes a feed tube body and a feed nozzle detachably connected to its lower end.

[0007] Furthermore, the flow control mechanism includes a cylinder, several valves, a telescopic piston rod, and an extension connecting rod. The cylinder is located at the upper end of the feed pipe, and the several valves are distributed on the side of the cylinder and connected to an external air source. The cylinder is driven by the telescopic piston rod, and the lower end of the telescopic piston rod is connected to the extension connecting rod. The extension connecting rod is movably disposed within the feed pipe and its up-and-down movement is used to block or open the feed nozzle.

[0008] Furthermore, the connecting valve includes a relay connecting pipe, a socket valve, and a sealing ring. One end of the relay connecting pipe is connected to the socket valve, and the other end is connected to the feed pipe through the sealing ring.

[0009] Furthermore, the fastening connection structure includes a first ring assembly, a second ring assembly, a swing shaft, and a pressure rotary handle. The first ring assembly and the second ring assembly are hinged on one side and are together sleeved on the outside of the connection between the relay connecting pipe and the guide pipe. A swing shaft is movably provided at one end of the first ring assembly, and the pressure rotary handle is movably connected to the swing shaft and one end of the second ring assembly. By rotating the handle, the first and second ring assemblies can be tightened, applying pressure to the connection.

[0010] Furthermore, the flow meter includes a pipe clamping ring and a flow meter body, wherein the pipe clamping ring is detachably connected to the feed pipe.

[0011] The beneficial effects of this utility model are: 1. Precise flow control: The opening of the feed nozzle can be precisely controlled by the piston rod driven by the cylinder and the extended connecting rod, so as to realize the real-time flow regulation and quantitative feeding of the material flowing into the purification equipment, which greatly improves the accuracy and stability of process control.

[0012] 2. Improved sealing performance: The unique fastening connection structure effectively enhances the sealing performance at the interface between the connecting valve and the feed pipe through mechanical pressurization, fundamentally preventing leakage and ensuring production safety and zero material waste.

[0013] 3. Good adaptability: The feed nozzle adopts a detachable design, which makes it easy to replace different specifications of feed nozzles according to different purification equipment interfaces, enhancing the versatility and flexibility of the device.

[0014] 4. Real-time monitoring: The integrated flow meter can monitor and measure the feed flow in real time, providing data support for automated control. Attached Figure Description

[0022] Please refer to the following: Figures 1 to 3 The feeding device of the extraction liquid purification equipment of this utility model includes: The system comprises a feed pipe 1, a flow control mechanism 2, a guide pipe 3, a connecting valve 4, a fastening connection structure 5, and a flow meter 6. The flow control mechanism 2 is mounted on the feed pipe 1. One end of the guide pipe 3 is connected to the side of the feed pipe 1, and the other end of the guide pipe 3 is connected to the connecting valve 4. The fastening connection structure 5 is provided at the connection between the guide pipe 3 and the connecting valve 4. The flow meter 6 is disposed between the fastening connection structure 5 and the flow control mechanism 2, and the flow meter 6 is connected to the guide pipe 3.

[0023] Specifically, when the feeding device of the extraction purification equipment of this utility model is in operation, the connecting valve 4 is connected to the external feed pipeline, and the feed pipe 1 can be connected to the external extraction purification equipment; the fastening connection structure 5 is used to reinforce the connection between the connecting valve 4 and the guide pipe 3, so that the feed material can be introduced through the guide pipe 3 and then enter the feed pipe 1; at this time, the flow meter 6 connected to the guide pipe 3 can be used to measure the flow rate of the liquid entering the guide pipe 3; the flow control mechanism 2 set on the feed pipe 1 can control the real-time flow rate from the feed pipe 1 into the external purification equipment; and quantitatively control the flow rate of the liquid flowing into the purification equipment.

[0024] Furthermore, the feed pipe 1 has a feed pipe body 101 and a feed nozzle 102; the feed nozzle 102 is detachably disposed at the lower end of the feed pipe body 101. The feed nozzle 102 can be easily disassembled, facilitating connection to different types of purification equipment and other devices.

[0025] Furthermore, the flow control mechanism 2 includes a cylinder 201, several valves 202, a telescopic piston rod 203, and an extension connecting rod 204; the cylinder 201 is disposed at the upper end of the feed pipe 101 relative to the feed nozzle 102, and the several valves 202 are distributed on the side of the cylinder 201; the cylinder 201 is drivenly connected to the telescopic piston rod 203, and the lower end of the telescopic piston rod 203 is connected to the extension connecting rod 204, which is movably disposed within the feed pipe 101. Specifically, two air valves 202 may be provided on the side of the cylinder 201. Each air valve 202 is connected to an external air source. Thus, the external air source can be used as power to drive the telescopic piston rod 203, which is movably disposed in the cylinder 201, to move downward or upward. This causes the extension connecting rod 204 to move downward to gradually block the feed nozzle 102, or to move upward to gradually release the blockage of the feed nozzle 102.

[0026] Furthermore, the connecting valve 4 includes a relay connecting pipe 401, a socket valve 402, and a sealing ring 403; one end of the relay connecting pipe 401 is connected to the socket valve 402, and the other end of the relay connecting pipe 401 is provided with the sealing ring 403; the sealing ring 403 is disposed between the relay connecting pipe 401 and the feed pipe 3. The socket valve 402 can be connected to an external incoming material pipe via a socket connection.

[0027] Furthermore, the fastening connection structure 5 includes a first ring assembly 501, a second ring assembly 502, a swing shaft 503, and a pressure rotating handle 504; the first ring assembly 501 and the second ring assembly 502 are hinged to one side, and the connection between the relay connecting pipe 401 and the guide pipe 3 is located between the first ring assembly 501 and the second ring assembly 502; the swing shaft 503 is movably disposed at one end of the first ring assembly 501, the pressure rotating handle 504 is movably connected to the swing shaft 503, and the pressure rotating handle 504 is movably connected to one end of the second ring assembly 502. Specifically, when the user needs to pressurize the connection between the relay connecting pipe 401 and the guide pipe 3 to seal the connection, the first ring assembly 501 and the second ring assembly 502 can be sleeved outside the connection. Then, the pressure rotary handle 504 is swung so that the lower end of the pressure rotary handle 504 rotates along the swing shaft 503 to connect with the second ring assembly 502. After that, the pressure rotary handle 504 is continued to be rotated, which can continuously reduce the relative distance between the first ring assembly 501 and the second ring assembly 502. Thus, the connection between the relay connecting pipe 401 and the guide pipe 3 can be pressurized, thereby simultaneously pressurizing the sealing ring 403 connected between the two to form a good seal.

[0028] Furthermore, the flow meter 6 has a pipe clamping ring 601 and a flow meter body 602. The pipe clamping ring 601 is detachably connected to the feed pipe 3, and the flow meter body 602 is connected to both the pipe clamping ring 601 and the flow meter body 602.

[0029] In summary, the feeding device of the extract purification equipment of this utility model mainly consists of a feeding pipe 1, a flow control mechanism 2, a guide pipe 3, a connecting valve 4, a fastening connection structure 5, and a flow meter 6.

[0030] During operation, the connecting valve 4's sleeve valve 402 is connected to the external incoming material pipeline, and the feed nozzle 102 of the feed pipe 1 is connected to the feed inlet of the external purification equipment. The material flows sequentially through the connecting valve 4 and the guide pipe 3, enters the feed pipe 1, and finally flows into the purification equipment.

[0031] The flow meter 6 is fixed to the feed pipe 3 via a pipe clamping ring 601, measuring the instantaneous and cumulative flow of the material in real time. The operator can adjust the flow control mechanism 2 based on the reading of the flow meter 6. Specifically, by controlling the opening and closing of different valves 202 on the cylinder 201, the telescopic piston rod 203 and its lower extension connecting rod 204 are driven to move up and down. When the extension connecting rod 204 moves downward, it gradually blocks the feed nozzle 102, reducing or cutting off the flow; when it moves upward, it opens the channel, increasing the flow. Through the aforementioned method, precise and quantitative control of the material entering the purification equipment is achieved.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
