Mixer and application thereof

Abstract

The invention discloses a mixer and application thereof. The mixer is provided with at least one thin conveying pipe, a thick conveying pipe, and a mixed slurry output pipe, wherein the pipe diameter of the thick conveying pipe is more than that of the thin conveying pipe, and one end of the thick conveying pipe is sealed; the mixed slurry output pipe is communicated with the sidewall close to the sealed end of the thick conveying pipe and changes the material flowing direction; the at least one thin conveying pipe extends into the thick conveying pipe from the sealed end, the extension amount of the thin conveying pipe in the thick conveying pipe exceeds the communication port of the thick conveying pipe and the mixed slurry output pipe, and the thin conveying pipe is partially overlapped with the thick conveying pipe; and the caliber of the mixed slurry output pipe is increased from the communication port with the thick conveying pipe to a discharge port. According to the invention, the shortcomings in the prior art are overcome, and high-efficiency and smooth mixing of two fluids with greater flow difference is realized.

Description

Technical field [0001] The invention relates to mixing equipment, in particular to a mixer and its use. Background technique [0002] In industrial production, it is often necessary to mix two fluids with a large difference in flow rate, especially for operations where the mixing process of the two fluids is accompanied by chemical reactions, and the mixing effect will have a significant impact on the properties of the obtained product. Take the mixing of soy milk and coagulant as an example. The mixing of soy milk and coagulant (commonly known as "Dian Nao") is the most critical operation in tofu processing. The mixing effect of soy milk and coagulant directly determines the quality of tofu (hardness, fineness, taste) Etc.) and production rate. In the braining process, the ratio of the amount of soybean milk to coagulant is 15-25:1, so the flow rate of the two fluids between soybean milk and coagulant is relatively large, the general flow ratio is as high as 20-30:1, and the re...

Problems solved by technology

[0003] However, although the existing fluid mixers have differences in structure, none of them can meet the needs of efficient and stable mixing of two fluids with a large flow gap.

The main types are: static mixer, which is generally connected to the pipeline. In order to achieve high efficiency and full mixing, there are various shapes of deflectors in the mixing chamber, and the mixer is small and hardly occupies a separate space. The fluid is mixed in a high-speed flow. Such a mixer is suitable for mixing two fluids in a large proportion. Although this is beneficial to achieve efficient mixing, the high flow rate controlled for the pursuit of mixing effect (working efficiency is proportional to the flow rate), resulting in The pressure and flow velocity of the mixed liquid after mixing are relatively large, and the impact force of the mixed liquid outlet is large, which is easy to generate foam; the high-speed fluid collision mixer is mostly used for the instantaneous mixing of binary binders and foamed plastics, and is suitable for two The flow rate is similar to the mixing of fluids. This mixer also has the problem that the impact force is too large to damage the structure of the product. When the mixed liquid is filled into the receiving container, it will form a splash due to a large impact, and foam will affect the structural state of the product; Venturi The effect mixer is suitable for mixing two fluids with a large flow difference, but there are also problems of high flow velocity of the mixed liquid and serious impact at the outlet

[0004] It can be seen that the above three types of fluid mixers all have the disadvantages of high mixed liquid outlet flow velocity and large impact force to varying degrees.

There are also improved designs that try to solve this problem by adding a reducer at the outlet of the mixer, but it brings another problem: it increases the investment in mixing equipment, resulting in high production costs; the production line is too long and takes up a lot of construction area; The equipment is complicated, which brings inconvenience to the installation and maintenance of the facilities

In the field of tofu production, none of the existing fluid mixing devices can meet the needs of high-efficiency and stable mixing of two fluids with large flow differences in the process of making tofu, which hinders the industrialization and large-scale process of tofu production.
