Description

Technical Field

[0001] The present invention belongs to the technical field of handheld filtration, and specifically relates to a quick-detachable handheld filtration device. Background Art

[0002] Silybin, the main substance in silymarin, is a crystal containing 1 molecule of water, with a melting point of 167 degrees Celsius and decomposition at 180 degrees Celsius; silybin is soluble in acetone, ethyl acetate, methanol, ethanol, slightly soluble in chloroform, and insoluble in water. The solubility of silymarin in water is 0.0401 mg / ml. Silymarin is widely used in the clinic to treat acute and chronic hepatitis, cirrhosis and liver damage. In recent years, with the development and improvement of pharmacological experimental methods, it has been found that it also has anti-tumor, anti-inflammatory, lipid-lowering, and diabetes treatment effects.

[0003] During the experiment of silymarin, in order to facilitate screening and filtration, most of the experiments were done manually in the laboratory through screening and washing, thus achieving manual control of screening and ensuring the operability of the experiment.

[0004] However, the filter screen and frame of the existing handheld filtering device are integrated, and the silymarin needs to be screened and washed for a long time with high intensity. Once the screen screen is damaged, the screen screen cannot be replaced alone, resulting in the entire device being unable to continue to be used normally. Remaking it requires high costs, and the screen screen of the positive film also needs to be cut neatly and laboriously to fit the filtering device. Summary of the invention

[0005] In order to solve the above problems, this paper proposes a quick-detachable handheld filtering device, wherein a handle is provided on the outside of the handheld filtering device, and a filter screen is provided on the inside of the handheld filtering device in a separated manner.

The disassembly and assembly chuck is in the form of a clamping surface that cooperates with the welding chuck, so that the screen cut by the cutting blade can be conveniently pressed and straightened, thereby ensuring that the screen can be quickly cut and then directly pressed and installed, and the opening and closing guide groove on the outer side enables it to be installed in an integrated manner with the locking hoop, and allows the locking hoop to open and close stably, which is convenient for the cutting blade on the top surface of the locking hoop to cooperate with the cutting blade of the welding chuck to cut the screen and install the welding chuck.

[0009] The locking hoop is a double semicircular clamping type locking hoop, and both ends of the two-petal locking hoop are clamped and connected to each other by flipping the locking screw, and a cutting blade is provided on the outer side of the top surface of the locking hoop, and a clamping groove is provided in the inner concave manner of the inner side of the locking hoop, and a guide column is provided on the inner bottom surface of the clamping groove, and the clamping groove is connected to the disassembly chuck displacement by the guide column in an outward expansion or inward contraction manner, and a sealing ring is provided on the inner side of the clamping groove in a compression manner, and the two chucks can be conveniently combined and connected and fixed through the locking hoop, and the cutting blade through the top surface can also be coordinated with the cutting blade of the welding chuck to realize the cutting function of the screen, and the design of guiding the locking hoop to move with the disassembly chuck through the guide column realizes the stable guiding opening and closing of the locking hoop, and ensures that the welding chuck can be installed and cut vertically downward.

[0010] The screen is a screening type sheet screen, and its shape is the same as the outer diameter of the end faces of the welding chuck and the disassembly chuck. It is clamped between the welding chuck and the disassembly chuck so that the entire filtering device can be easily disassembled and assembled. Not only can it be replaced according to different screening apertures, but the screen can also be replaced due to damage, thereby eliminating the need to make multiple filtering devices and reducing costs.

[0011] Beneficial effects:

[0012] By using the chuck and the clamp locking method, the screen can be replaced conveniently and quickly, which is convenient for production, effectively reduces costs, and realizes the replacement of the screen. When the screen is damaged, the screen can be directly replaced to extend the service life of the device. Different mesh screens can be replaced according to different needs to increase the utilization rate of the device. The screen can also be directly cut by the provided cutting blade. There is no need to regularly cut the screen according to the shape of the inside of the filter device. The screen can be installed by directly pressing, which greatly increases the installation efficiency of the screen.

[0013] By directly using a round tube cut as a loading tube, the production of the filtering device is facilitated and the cost can be effectively reduced. A handle is provided on the outside of the tube to facilitate manual screening.

[0014] By arranging a cutting blade on the bottom surface of the welding chuck, the screen can be cut by directly plugging it downward in cooperation with the cutting edge of the locking clamp, so that the screen can be cut and directly installed without measuring and trimming the screen, which greatly increases work efficiency.

[0015] By means of a disassembly and assembly chuck with a pressing surface that cooperates with the welding chuck, the screen cut by the cutting blade can be conveniently pressed and straightened, thereby ensuring that the screen can be quickly cut and directly pressed and installed. The opening and closing guide groove on the outside enables it to be installed integrally with the locking hoop, and allows the locking hoop to open and close stably, making it convenient for the cutting blade on the top surface of the locking hoop to cooperate with the cutting blade of the welding chuck to cut the screen and install the welding chuck.

[0016] The two chucks can be conveniently connected and fixed together by locking the clamp, and the screen therein can also be clamped and fixed, and the subsequent removal and replacement of the screen can also be facilitated.

[0017] The locking hoop can conveniently realize the combined connection and fixation of the two chucks, and the cutting blade on the top surface can also be coordinated with the cutting blade of the welding chuck to realize the cutting function of the screen. The design of the locking hoop guiding the movement of the disassembly and assembly chuck through the guide column realizes the stable guiding opening and closing of the locking hoop, ensuring that the welding chuck can be installed and cut vertically downward.

[0018] By clamping it between the welding chuck and the disassembly chuck, the entire filtering device can be easily disassembled and assembled. Not only can it be replaced according to different screening apertures, but the screen can also be replaced due to damage, thereby eliminating the need to manufacture multiple filtering devices and reducing costs.
