Abstract
Description
Technical Field
[0001] This utility model relates to the field of spinning equipment technology, and in particular to a spinning oil circulation device for ultrafine denier nylon 6. Background Technology
[0002] As a crucial part of the spinning process, the spinning oiling system suffers from the high concentration of crude oil (over 90%). At low temperatures, this can lead to stratification of the solute, solution, and additives. This phenomenon results in uneven concentration and composition during emulsion preparation, and in severe cases, can cause emulsion spoilage or the formation of other impurities, significantly impacting oiling during spinning. Traditional methods involve placing the oiling agent in a high-temperature environment, but this doesn't address the root causes: 1. In winter, placing it in a high-temperature environment doesn't completely resolve the stratification; it only increases the fluidity of some crude oil, failing to achieve uniform mixing. 2. Prolonged exposure to high temperatures can cause some crude oil to react, leading to spoilage or the volatilization of additives. Therefore, the solution is a device that can achieve uniform mixing of crude oil even at low temperatures while maintaining its quality. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a simple and easy-to-operate ultrafine denier 6 spinning oil circulation device, which can be used to mix crude oil evenly in winter without causing the oil to change in quality.
[0004] This invention is achieved as follows: a circulating device for ultra-fine denier nylon 6 spinning oil, comprising...
[0005] An oil drum has an oil inlet at the top and an oil outlet at the bottom, with a connector provided on the oil outlet;
[0006] A crude oil storage tank is installed at a position higher than the oil drum. The top is connected to the oil drum via an oil inlet pipe, and the bottom is provided with an oil outlet pipe connected to the oil drum's inlet. A refrigeration coil is installed inside the crude oil storage tank. The refrigeration coil is connected to a chilled water pipe, and the chilled water pipe is equipped with a chilled water circulation pump.
[0007] An oil circulation pump is installed on the oil inlet pipe;
[0008] A temperature control device includes a temperature sensor and a controller. The temperature sensor is installed inside the crude oil storage tank, and the controller is communicatively connected to the temperature sensor and a chilled water circulation pump.
[0009] The advantages of this invention are: the oil circulation device allows the oil in the oil drum to be uniformly mixed with crude oil at low temperatures, while also increasing the temperature of the crude oil, improving its fluidity, and enhancing the emulsification effect of the oil; it also reduces the storage time of crude oil, eliminating the need to store it in a high-temperature area for several days before use, allowing it to be used directly.

Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0014] Please see Figure 1 As shown, the present invention provides a superfine denier nylon 6 spinning oil circulation device 100, which includes an oil drum 1, an oil storage tank 2, an oil circulation pump 3, and a temperature control device 4.
[0015] The oil drum 1 has an oil inlet 11 at the top and an oil outlet 12 at the bottom. A connector 13 is provided on the oil outlet 12. The oil drum 1 stores crude oil.
[0016] The crude oil storage tank 2 is installed higher than the oil drum 1. The top is connected to the oil drum 1's connector 13 via an oil inlet pipe 21, and the bottom is provided with an oil outlet pipe 22 connected to the oil drum 1's oil inlet 11. A refrigeration coil 23 is installed inside the crude oil storage tank 2. The cooling coil 23 is connected to a chilled water pipe 24, and the chilled water pipe 24 is equipped with a chilled water circulation pump 25. The oil circulation pump 3 is installed on the oil inlet pipe 21. The temperature control device 4 includes a temperature sensor 41 and a controller 42. The temperature sensor 41 is installed inside the crude oil storage tank 2, and the controller 42 is communicatively connected to the temperature sensor 41 and the chilled water circulation pump 25. The temperature sensor 41 senses the oil temperature in the crude oil storage tank 2 and transmits it to the controller 42 in real time. The controller 42 controls the opening and closing of the chilled water circulation pump 25 according to the set value, thereby controlling the circulation of chilled water in the cooling coil 23.
[0017] Operation process: First, the temperature inside the crude oil storage tank 2 is set to 25℃ by the controller 42. After all the pipelines are connected, the oil circulation pump 3 is turned on to draw the crude oil from the oil outlet 12 at the bottom of the oil drum 1 and send it to the crude oil storage tank 2 through the oil circulation pump 3. Then, due to the height difference between the crude oil storage tank 2 and the oil drum 1, it flows back to the top of the oil drum 1 by gravity, thus forming a closed circulation system. The heat generated in the circulation is sensed by the temperature sensor 41 to detect the oil temperature in the crude oil storage tank 2 and transmitted to the controller 42 in real time. The controller 42 controls the opening and closing of the chilled water circulation pump 25 according to the set value, thereby controlling the circulation of chilled water in the cooling coil 23, thereby removing the heat generated in the circulation and automatically controlling the temperature inside the crude oil storage tank 2 to remain constant.
[0018] With increased crude oil fluidity, the emulsion preparation time can be reduced from 1.0 hour to 0.5 hours. At the same time, the emulsification effect of the oil is better, the emulsion concentration is more uniform, which can improve the oiling rate of the product, reduce oil splashing, and ensure more uniform oiling and more ideal dyeing effect, thus improving the product in terms of process.
[0019] The advantages of this invention are: the oil circulation device allows the oil in the oil drum to be uniformly mixed with crude oil at low temperatures, while also increasing the temperature of the crude oil, improving its fluidity, and enhancing the emulsification effect of the oil; it also reduces the storage time of crude oil, eliminating the need to store it in a high-temperature area for several days before use, allowing it to be used directly.
[0020] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
