Oiling agent defoaming device

Abstract

The invention relates to an oiling agent defoaming device, which is applied to defoaming an oil immersion tank, an oil bath tank and a water bath drawing tank of various chemical fibres and polyester staple fibres. The oiling agent defoaming device is arranged on the oil bath tank of chemical fibre oil bath drawing equipment and communicated with an oiling agent circulation pump installed on an oiling agent conveying pipeline. The oiling agent defoaming device is characterized by comprising a distribution pipeline, a decompression valve, a filter and nozzles; the distribution pipeline is communicated with an outlet oiling agent circulation pipeline of the oiling agent circulation pump; the distribution pipeline is arranged along the periphery of the upper edge opening on the oil bath tank; and a plurality of nozzles are uniformly distributed on the distribution pipeline and used for eliminating a lot of foams generated by a fluctuant oiling agent. The oiling agent defoaming device disclosed by the invention has the advantages that: without the help of external power or a defoaming agent and with the help of a self-supported power source, a lot of foams generated by circulation fluctuation of the oiling agent can be effectively eliminated without adding the defoaming agent, therefore, the consumption of the oiling agent is effectively reduced, the pollution on the environment, resulted from overflow foams, can be avoided, and the purposes for saving energy, reducing consumption and protecting the environment can be achieved.

Description

[0001] technical field [0002] The oil-bath drafting equipment of the present invention relates to chemical fiber mechanical equipment, and specifically relates to a defoaming device suitable for oil immersion tanks, oil bath tanks and water-bath draft tanks of various chemical fiber polyester staple fibers. [0003] Background technique [0004] There are two kinds of defoaming forms for oil bath drafting equipment, one is fan suction defoaming barrel defoaming. It is to use the centrifugal fan to suck out the foam and transport it to the defoaming tank. Driven by the rotation of the airflow in the defoaming tank, the foam is broken into liquid and flowed back into the tank under the action of centrifugal force, and the air is discharged at the same time. When this device is practical, there are several shortcomings. One is that the foam collection port cannot completely cover the foam-generating part of the overall tank, and the foam will still overflow in some areas. Th...

Problems solved by technology

When this device is practical, there are several shortcomings. One is that the foam collection port cannot completely cover the foam-generating part of the overall tank, and the foam will still overflow in some areas. The other is that when the suction port sucks the foam, the current After the foam on the side is sucked away, it will inevitably cause the nearby airflow to follow and enter the suction port. As the airflow is continuously inhaled, the generated airflow prevents the nearby foam from moving to the suction port, resulting in air suction.

Due to the above two points, the defoaming effect is not ideal

Another method is to manually spray the defoamer on the foam from time to time, which takes a certain amount of manpower and energy, and the efficiency is very low. At the same time, the addition of the defoamer will change the original oil composition, which in turn affects the production requirements. Oils have adverse effects

In this way, there are not only defoamer costs, but also labor costs, and there are unfavorable factors that destroy the oil composition, so it is not a good way
