Description

Technical Field

[0001] This utility model relates to the field of mixer-related products, specifically a static mixer. Background Technology

[0002] A static mixer is a high-efficiency mixing device without moving parts. The device uses a fixed mixing unit inside the pipeline as its core structure. It changes the fluid flow state through cutting, shearing and rotation to achieve dispersion and mixing of various media such as gas / gas, liquid / liquid and gas / liquid. It is widely used in more than 20 fields such as chemical, petroleum, food, medicine, and environmental protection.

[0003] However, the existing static mixers use a single mixing chamber shape and a fixed mixing chamber arrangement, resulting in poor mixing effect for fluid media and thus have defects. Utility Model Content

[0004] The purpose of this invention is to provide a static mixer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a static mixer, including a female mixer head, a male mixer head, and a mixing unit. The mixing unit is located inside the female mixer head and is composed of five stacked mixing seats. Each mixing seat has a mounting groove, and a mixing plate is provided in the mounting groove. The mixing plate has multiple mixing cavities, and the multiple mixing cavities are all arranged in a "b" shape. The mixing seat has a through-hole corresponding to the position and shape of the mixing cavity.

[0006] As a preferred embodiment of this utility model, both the female and male mixer heads are provided with threaded holes on one side, and dust plugs are inserted into the threads of the threaded holes.

[0007] As a preferred embodiment of the present invention, one side of the mixing plate is provided with a receiving groove, the mixing seat is provided with a through hole communicating with the receiving groove, and a positioning pin is inserted between the five mixing seats.

[0008] As a preferred embodiment of this invention, the mixing seat is made of stainless steel and the mixing plate is made of plastic.

[0009] As a preferred embodiment of this invention, the female mixer head is provided with a sealing gasket, which is fitted inside the male mixer head.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This static mixer has a mixing unit consisting of five stacked mixing seats. A mixing plate is inserted into each mixing seat and the mixing unit is installed inside the male mixer head. The male mixer head with the mixing unit installed is screwed and locked to the female mixer head.

[0012] This static mixer has multiple mixing chambers on the mixing plate arranged in a "b" shape. After the fluid flows in, it is accelerated at the straight pipe of the mixing chamber to the semi-circular part and then generates a vortex. The fluid at the vortex produces a cutting and shearing effect with the fluid flowing in afterward. The fluid is drawn in through the central circular hole at the semi-circle and generates a rotational effect, thereby mixing the fluid. The mixing unit can make the fluid undergo multiple mixing processes, so that the multiple media in the fluid can achieve a thorough mixing effect.

[0013] This static mixer improves the shape and arrangement of the mixing chambers, increases the number of mixing chambers, and enhances the mixing effect of the fluid medium. This allows subsequent HPLC analysis equipment to reduce baseline noise, improve sensitivity, and increase gradient accuracy. At the same time, it reduces mixing and delay volumes without sacrificing mixing efficiency, thereby improving the reaction efficiency of post-column derivatization. Attached Figure Description
