Problems solved by technology

[0003] The oiling device currently used in production has the following problems. The oil tank adopts internal coils to cool down, and oil dirt is easy to adhere to the coils. The oil will be unstable due to shearing and uneven mixing in the tank during use. The unstable oil agent in the tank cannot be removed in time, which has a destructive effect on the new oil agent, causing a vicious cycle, and the continuous use performance of the oil tank is reduced

Abstract

The invention discloses an oiling device and method for improving the stability of an oil agent, and belongs to the technical field of chemical fiber production. The oiling device comprises a circulating storage tank, an oil agent delivery pump, an external circulating filter, an external circulating heat exchanger and an oil tank; the circulating storage tank is connected with the oil inlet end of the oil agent delivery pump through a pipeline, the oil outlet end of the oil agent delivery pump is connected with the oil inlet end of the external circulating filter through a pipeline, the external circulating filter is connected with the oil inlet end of the external circulating heat exchanger through a pipeline, the oil outlet end of the external circulating heat exchanger is connected with the oil tank through a pipeline, and the oil tank is connected with the circulating storage tank through a pipeline, so that a circulating loop is formed; the bottom of the oil tank is provided with an emptying pipe with an emptying pneumatic valve. According to the oiling device, mixing uniformity of the oil agent in the oil tank can be improved, the possibility of oil dirt deposition in the oil tank is decreased, the stability of the oil agent is effectively improved, and oxidation destruction of air and humidity on the oil agent in the oil tank can be reduced.

Description

technical field [0001] The invention relates to the technical field of chemical fiber production, in particular to an oiling device and a method for improving the stability of an oil agent. Background technique [0002] The oil agent plays the role of softness, smoothness, antistatic and wear resistance in the production of chemical fiber. With the development of chemical fiber products in the direction of functionalization, new high-functional oil agents are developed accordingly, and multi-component functional The compounding of additives, emulsifiers, silicone oil and other ingredients has brought about an increase in the complexity of the components of the oil itself. On the basis of improved functionality, due to the differences in the particle size and component compatibility of the oil itself 1. The destructiveness of the shearing process during use, and the destructiveness of the external environment to the oxidation of the oil, so it is necessary to develop an oilin...
