Description
Technical Field
The invention relates to the field of liquid reaction kettles, in particular to a water-based titanium alloy cutting fluid reaction kettle.
Background
Titanium is a structural metal developed in the last 50 th century, and titanium alloy has the advantages of high strength, corrosion resistance, good heat resistance and the like, and is an important alloy for developing aviation and high-end equipment. However, titanium alloys are also difficult to machine due to these properties, and cutting with ordinary metals results in accelerated wear of the tool tip and unacceptable quality of the work piece, and therefore, selection of an appropriate metal cutting fluid is of great importance.
Most of metal cutting fluids in the prior art are emulsified oil products, and the viscosity of the products is not suitable for being used in titanium metal cutting, so that the phenomenon of adhesion and abrasion of the titanium metal can be caused. Therefore, water-based cutting fluids have become the subject of development of titanium metal cutting fluids. Water-based cutting fluids have low oil content or do not contain oily components and therefore have less environmental impact. The water-based cutting fluid is generally an emulsified or galactized product, which contains a large amount of lubricants, emulsifiers and the like, particularly, the conventional oil reaction kettle is adopted for the water-based titanium alloy cutting fluid adopting the polyethylene glycol ester lubricants, so that the demulsification phenomenon caused by uneven stirring or excessive emulsification can be caused, and the product quality of the water-based titanium alloy cutting fluid is greatly influenced. Therefore, a reaction kettle suitable for the water-based titanium alloy cutting fluid needs to be developed.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the reaction kettle suitable for the water-based titanium alloy cutting fluid, in particular suitable for the water-based titanium alloy cutting fluid containing the polyethylene glycol ester lubricant, and the reaction kettle has the advantages of good emulsification effect, difficult demulsification of finished products and the like.
The polyethylene glycol esters are generally used in the fields of chemical industry, papermaking, spinning and the like, are used as emulsifying agents, have good emulsifying, lubricating and softening properties, can be dissolved in various organic solvents, and are generally dispersed in water. The water-based titanium alloy cutting fluid is generally used as a lubricant, but when the water-based titanium alloy cutting fluid is added into a water phase and is conventionally emulsified by a common reaction kettle, a large amount of bubbles are generated in the emulsification process due to the presence of a spoiler in the reaction kettle, which is fatal to the reaction kettle, so that the dosage of an antifoaming agent needs to be increased in raw materials, the antifoaming agent commonly used in the field is siloxane, the adhesion abrasion phenomenon of the water-based titanium alloy cutting fluid is increased due to the introduction of a large amount of siloxane, and the phenomenon of insufficient emulsification and easy demulsification exists in the reaction kettle without the spoiler.
The inventor surprisingly finds that the spiral spoiler strip is adopted to replace a common vertical spoiler through careful research, so that the phenomenon of excessive bubbles and demulsification caused by insufficient emulsification in the prior art caused by excessive emulsification can be solved. The specific technical scheme of the invention is as follows:
a reaction kettle for water-based titanium alloy cutting fluid comprises a kettle body, wherein the kettle body comprises a stirring shaft which is driven by a motor arranged at the top and extends into an inner cavity of the kettle body, a stirring paddle is arranged on the stirring shaft, and the other end of the stirring shaft is fixed in a support frame at the bottom; a heating pipe is sleeved outside the stirring shaft; the top of the stirring kettle is also provided with a feeding hole, and the bottom of the stirring kettle is provided with a discharging hole; a spiral turbulence strip is arranged in the inner cavity of the kettle body and clings to the inner wall; and the water-based titanium alloy cutting fluid comprises a polyethylene glycol ester lubricant.
In a preferred embodiment of the invention, the stirring paddle has 4 to 6 blades, and the blades are all in a plane vertical to the stirring shaft. The paddle is formed by overlapping a lower paddle and an upper paddle. Preferably, the upper paddle has a slightly smaller area than the lower paddle. More preferably, the cross-sections of the upper and lower blades form a step shape.
In a preferred embodiment of the invention, the number of the stirring paddles is 3, and the stirring paddles are uniformly distributed on the stirring shaft; correspondingly, the number of the heating pipes is 2, and the heating pipes are positioned between two adjacent stirring paddles. Preferably, the diameter of the heating pipe is larger than the length of the paddle. The stirring and dissolving process of the polyethylene glycol ester system needs heating, and the heating is beneficial to dissolving the components under normal conditions, so that the process time can be reduced, the production flow can be shortened, and the cost can be reduced.
In a preferred embodiment of the invention, the spiral direction of the turbulence strips is consistent with the rotation direction of the stirring paddle, the included angle between the turbulence strips and the horizontal plane is 15-45 degrees, and the width of the turbulence strips is 1/8-1/15 of the inner diameter of the kettle body. It is believed that the included angle of the turbulence strip and the horizontal plane is too large, so that the turbulence effect is enhanced, bubbles are more easily generated, and when the included angle of the turbulence strip and the horizontal plane is too small, the turbulence effect is too weak, the emulsification effect is poor, and therefore the selection of a proper included angle plays a crucial role in the stability of the water-based titanium alloy cutting fluid. Preferably, the included angle between the turbulence strips and the horizontal plane is 30 degrees, and the width of the turbulence strips is 1/10 of the inner diameter of the kettle body.

In a preferred embodiment of the present invention, the polyethylene glycol ester lubricant is selected from one or more of polyethylene glycol monostearate, polyethylene glycol distearate, polyethylene glycol monolaurate, polyethylene glycol dilaurate, polyethylene glycol monooleate, and polyethylene glycol dioleate. The above polyethylene glycol fatty acid esters provide similar lubricating properties.
The reaction kettle of the water-based titanium alloy cutting fluid is mainly used for mixing and stirring the water-based titanium alloy cutting fluid.

The stirring speed in the process is not too high, preferably 30-50 rpm.
The invention has the beneficial effects that:
1. compared with the common spoiler, the reaction kettle for the water-based titanium alloy cutting fluid reduces the spoiler effect, avoids the phenomenon of excessive bubbles caused by excessive emulsification, reduces the use of a defoaming agent, and reduces the adhesive wear caused by the cutting fluid by arranging the spiral spoiler strip.
