Description

Technical Field

[0001] This utility model relates to the field of feeding technology, specifically a high-pressure preparation feeding funnel. Background Technology

[0002] High-pressure preparative column technology is a key component in high-performance liquid chromatography (HPLC) and ultra-high-performance liquid chromatography (UPLC). It is mainly used for the separation and purification of high-purity compounds and is widely used in pharmaceuticals, biotechnology and environmental analysis. This technology is based on high pressure (tens to hundreds of MPa) driving the mobile phase, and achieves efficient separation through the selective adsorption of sample components by the stationary phase.

[0003] In the production process of liquid mixtures, the use of high-pressure preparation columns requires liquid mixing fillers, but the addition port is too narrow, and the filler needs to be stirred evenly. If the pause time is too long, sedimentation will occur, and it will need to be stirred again, making the feeding process too cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure preparation feeding funnel to address the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a funnel assembly is included, a feeding assembly is provided inside the funnel assembly, and a limiting assembly is also provided inside the funnel assembly, the limiting assembly being able to fix the funnel assembly.

[0006] Furthermore, the funnel assembly includes a protective shell, inside which a funnel component is disposed, and a discharge pipe is connected to the bottom of the funnel component.

[0007] Furthermore, the feeding assembly includes a drive source fixedly disposed inside the protective shell. The output end of the drive source is provided with a rotating shaft, which extends through the inside of the discharge pipe. One end of the rotating shaft located inside the discharge pipe is connected to one end of an auger screw conveyor, and the other end of the auger screw conveyor is located at the connection between the discharge pipe and the funnel component.

[0008] Furthermore, the screw conveyor is provided with a drive shaft at one end of the connection between the discharge pipe and the funnel component. The drive shaft is provided with a stirring rod and a scraper, which corresponds to the position of the funnel component. The drive shaft is also provided with fan blades.

[0009] Furthermore, the limiting component includes two limiting cylinders fixedly mounted on the protective shell. The bottom of the two limiting cylinders is provided with rubber rings, and the two rubber rings correspond to the bottom position of the protective shell. Each of the two limiting cylinders is provided with a connector, and each of the two connectors is fitted with a rubber pad.

[0010] Furthermore, each of the two connecting parts is provided with a threaded post at its top, and the top of each of the two threaded posts extends to the top of the limiting cylinder. Each of the two threaded posts engages with a threaded sleeve, and each of the two threaded sleeves is rotatably connected to the two limiting cylinders. Each of the two limiting cylinders is fitted with a helical gear ring, and each of the two helical gear rings engages with a helical gear component. Each of the two helical gear components is connected to one end of a transmission rod, and the other ends of both transmission rods extend to the outside of the protective shell. Both transmission rods are rotatably connected to the protective shell, and each of the two transmission rods located outside the protective shell is provided with a handle.

[0011] Furthermore, the connector is also provided with two limiting posts, both of which penetrate the limiting cylinder.

[0012] Compared with the prior art, the high-pressure preparation feeding funnel provided by this utility model fixes the protective shell with a limiting component, and then starts the drive source. The rotation of the stirring rod prevents the raw material from settling under continuous stirring. The scraper prevents the raw material from sticking to the funnel wall. At the same time, the rotation of the fan blade makes the raw material vortex and quickly injects it through the discharge pipe under the rotation of the auger screw conveyor, reducing the time required for injection.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Please see Figure 1-4 This utility model provides a high-pressure preparation feeding funnel.

[0021] It includes a funnel assembly 1, a feeding assembly 2 is provided inside the funnel assembly 1, and a limiting assembly 3 is also provided inside the funnel assembly 1, which can fix the funnel assembly 1.

[0022] Preferably, the funnel assembly 1 includes a protective shell 11, a funnel component 12 is disposed inside the protective shell 11, and a discharge pipe 13 is connected to the bottom of the funnel component 12.

[0023] Preferably, the feeding assembly 2 includes a drive source 21 fixedly installed inside the protective shell 11. The output end of the drive source 21 is provided with a rotating shaft 22, which extends through the discharge pipe 13. One end of the rotating shaft 22 inside the discharge pipe 13 is connected to one end of an auger screw conveyor 23, and the other end of the auger screw conveyor 23 is located at the connection between the discharge pipe 13 and the funnel component 12.

[0024] Preferably, the screw conveyor 23 is provided with a drive shaft 24 at one end of the connection between the discharge pipe 13 and the funnel 12. The drive shaft 24 is provided with a stirring rod 25 and a scraper 26, which corresponds to the position of the funnel 12. The drive shaft 24 is also provided with a fan blade 27. When the drive source 21 is started, it drives the rotating shaft 22 to rotate, which causes the screw conveyor 23 to rotate, which in turn drives the drive rod 39 to rotate, causing the stirring rod 25, the scraper 26 and the fan blade 27 to start rotating.

[0025] Preferably, the limiting component 3 includes two limiting cylinders 31 fixedly mounted on the protective shell 11. The bottom of the two limiting cylinders 31 is provided with rubber rings 32, and the two rubber rings 32 correspond to the bottom position of the protective shell 11. Each of the two limiting cylinders 31 is provided with a connector 33, and each of the two connectors 33 is fitted with a rubber pad 34. Rotating the two handles 310 drives the two transmission rods 39 to rotate, causing the two helical gears 38 to rotate, which in turn drives the two helical gear rings 37 to rotate, causing the two threaded sleeves 36 to rotate, which in turn drives the two threaded columns 35 to start moving upward, causing the connectors 33 to move upward.

[0026] Preferably, each of the two connectors 33 has a threaded post 35 at its top, and the top of each threaded post 35 extends to the top of the limiting cylinder 31. Each threaded post 35 engages with a threaded sleeve 36, and each threaded sleeve 36 is rotatably connected to the two limiting cylinders 31. Each limiting cylinder 31 is fitted with a helical gear ring 37, and each helical gear ring 37 engages with a helical gear component 38. Each helical gear component 38 is connected to one end of a transmission rod 39, and the other end of each transmission rod 39 extends to the outside of the protective shell 11. Both transmission rods 39 are rotatably connected to the protective shell 11. Each end of each transmission rod 39 located outside the protective shell 11 is provided with a handle 310. Rotating the two handles 310 causes the two transmission rods 39 to rotate, which in turn causes the two helical gear components 38 to rotate, which in turn causes the two helical gear rings 37 to rotate, which in turn causes the two threaded sleeves 36 to rotate, which in turn causes the two threaded posts 35 to move upward, thus causing the connectors 33 to move upward.

[0027] Preferably, the connector 33 is also provided with two limiting posts 311, both of which penetrate the limiting cylinder 31.

[0028] When feeding is required, first place the protective shell 11 in the designated position so that the discharge pipe 13 is connected to the required feeding point. Then, turn the two handles 310 to drive the two transmission rods 39 to rotate, causing the two helical gear components 38 to rotate, which in turn drives the two helical gear rings 37 to rotate, causing the two threaded sleeves 36 to rotate, which in turn causes the two threaded posts 35 to move upward, causing the connecting piece 33 to move upward. The setting of the two limit posts prevents the threaded posts 35 from rotating, and then drives the rubber pad 34 to move upward, creating a negative pressure inside the limit cylinder 31, thus fixing the protective shell 11. Then, start the drive. The power source 21 drives the rotating shaft 22 to rotate, which in turn drives the auger screw conveyor 23 to rotate, which in turn drives the transmission rod 39 to rotate, causing the stirring rod 25, scraper 26, and fan blade 27 to start rotating. Then, raw materials are added into the funnel 12. The rotation of the stirring rod 25 prevents the raw materials from settling due to continuous stirring. The scraper 26 prevents the raw materials from sticking to the wall of the funnel 12. At the same time, the rotation of the fan blade 27 causes the raw materials to vortex and be quickly injected through the discharge pipe 13 under the rotation of the auger screw conveyor 23, reducing the time required for injection.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
