Description

A spiral interlayer multi-component online mixing device

technical field

The invention relates to a spiral interlayer type multi-component on-line mixing device applied to on-line mixing occasions, specifically a kind of on-line mixing of various small amounts of liquid solutes and liquid solvents at one time, and at the same time has the solubility of mixed solids. In-line mixing device for solute function.

Background technique

Online mixing has the characteristics of separate storage of solute and solvent, independent supply, instant blending, and centralized outflow. In many application scenarios such as online mixing and spraying of pesticides and instant blending of lubricating fluids, online mixing devices are essential.

Mixing uniformity is an important evaluation factor for online mixing devices. In the field of online spraying of pesticides, the online uniform mixing of pesticides (solute) and water (solvent) can better meet the effect of spray control. Usually, the ratio of pesticide to water is very low, so the amount of pesticide (solute) is small relative to the solvent (water), so it is often difficult to ensure that the pesticide is fully dispersed in water. At the same time, in order to meet the centralized spraying of multiple pesticides at one time and realize the centralized control of multiple crop diseases and insect pests, an online mixing device is required to meet the online mixing of various small amounts of pesticides and water at the same time; the formulations of commonly used pesticides include liquid formulations and powders However, the problem of how to realize online mixing of various liquid pesticides and solid pesticides with water in a drug mixing device has not yet been perfectly resolved. Another example is in the field of industrial lubrication. The quality of lubricating oil has a great influence on the lubricating effect. Lubricating oil mainly includes base oil (solvent) and various additives (solute): such as viscosity index improver, pour point depressant, antioxidant, Oily agents, antifoaming agents, etc., some of the lubricating oil additives are liquid components, and some are solid components. If the additive composition of lubricating oil can be changed in real time according to the required lubricating properties before lubrication, the properties of lubricating oil can be changed to provide better lubricating effect. Since various additive components are relatively small compared to the base oil, the required mixing device requires higher mixing efficiency to meet the uniform mixing of various solutes in the base oil.

At present, the commonly used online liquid-liquid mixing device mostly adopts the method of jet flow and spiral flow generation to realize the mixing of liquid medicine. For example, Chinese patent, application number 201010132393.3, title of invention: an automatic drug mixing device, this device and similar devices have an independent system to supply working fluid and water to mix, and adopt jet flow and post-installed spiral static mixing device to promote mixing. When it is small, the jet suction and mixing efficiency, and the mixing efficiency of the screw device are seriously reduced. The system cannot guarantee the uniformity of online mixing under small flow rates, and most of them can only mix a single pesticide. Other mixing devices, such as Chinese patent, application number 201610220373.9, name of invention: a composite static mixer, which welds the inlet conduit and the blade together, relies on the conduit to add additives in the radial direction, and relies on the blade to roll the fluid to promote Mixing, the device has low efficiency of uniform mixing of various solutes and solvents at a low flow rate, and although the structure is relatively simple, the mixing effect is not good. Another example is the Chinese patent 201610918892.2, the name of the invention: static mixer, and the Chinese patent 201710832962.7, the name of the invention: the static jet mixer, which adopts a special static mixing device structure arranged behind the entrance, and uses the sudden change of flow to achieve mixing. , so it will inevitably cause a large energy loss. Another example is the Chinese patent 201080010750.7, the name of the invention: coaxial compact static mixer and its use, which uses multiple coaxial mixing stages to assemble to form a cascaded static mixing device, which divides the overall flow channel to form small flow channels , to achieve mixing through fluid flow separation and recombination, this device also has the disadvantages of complex structure and large energy loss.

At present, most of the existing solid-liquid static mixing devices use jet negative pressure structure to absorb solid solute into the carrier fluid. The pressure mechanism attracts solid powder clusters into the carrier fluid to achieve mixing. This strategy can theoretically achieve solid-liquid mixing, but only relying on negative pressure to trigger solid injection can easily cause blockage of the solid injection point. Another example is the Chinese patent, application number 201010269703.6, title of invention: a two-phase multi-material online injection water plugging profile control method and equipment. In this invention, a jet negative pressure mechanism is also used to attract solid materials to mix with liquid, and there are also blockages and dispensing. A question of impreciseness. Another example is the Chinese patent, application number: 201410231851.7, title of invention: solid-liquid two-phase ratio mixing device, which uses a negative pressure mechanism to carry out material suction and motor supply in combination to work, and the device adds motor equipment, although it is helpful To avoid clogging and improve accuracy, but it increases the complexity of the system and is difficult to apply to the occasion of online mixing of a small amount of solid solute.

In the solid-liquid mixer 1, according to Bernoulli's principle, the solvent flows through the constriction pipe, the throat pipe, and the amplification pipe. Since the pressure of the front constriction pipe is greater than the pressure at the rear throat pipe, a pressure difference is formed, and the pressure difference between the two places increases. To a certain extent, the parallel branch connecting the constriction tube and the throat will generate through-flow to wash the solid solute and mix it with the solvent; The stacked flow channel allows the solvent to pass through, and the spiral seepage layer is tapered as a whole. When the fluid passes through, the velocity increases. When the total water head remains unchanged, the pressure decreases and the kinetic energy increases, which helps to prevent the solute from flowing through the seepage holes 63. The wall attachment effect produced during the outflow; the diameter of the seepage holes 63 on the solute pipe 62 and the density of its distribution gradually increase along the extension of the solute pipe 62, so that there is more seepage at the beginning, and less seepage after the pressure decreases with the extension of the solute pipe 62 The problem.
