Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of oil preparation tank technology, and more specifically to a weighing-metering spinning oil preparation tank. Background Technology
[0002] Oil mixing tanks are essential equipment in chemical fiber production. The oil used in chemical fibers is made by blending crude oil with demineralized water or other corrosion inhibitors in a specific ratio. To ensure uniform mixing, the tank is equipped with a steam heating coil, and the tank cover features a two-layer, three-blade agitator consisting of a cycloidal pinwheel planetary reducer. The oil mixing tank has a vertical cylindrical structure. The tank cover includes an oil inlet, a demineralized water inlet, and a manhole (inspection hole). The tank opening is welded with a stainless steel tank flange, and the bottom is connected with a semi-circular end cap.
[0003] The oil preparation tank can only display the liquid level of the spinning oil in the tank, but cannot measure the weight of the spinning oil, which makes it difficult to prepare the oil. In the existing technology, workers measure the weight of the spinning oil by installing a pressure sensor in the oil preparation tank. However, after the oil in the oil preparation tank is in contact with the pressure sensor for a long time, the elastic deformation of the pressure sensor will be irreversible. This will affect the accuracy of weighing at best, and directly damage the weighing device at worst. Utility Model Content
[0004] The purpose of this invention is to provide a weighing-type metering spinning oil mixing tank to solve the problems mentioned in the background art.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model slides an inner cylinder inside the outer cylinder of the spinning oil mixing tank and uses a top rod to support the inner cylinder. When weighing the oil, the length of the top rod is adjusted so that the inner cylinder contacts the weighing sensor, and the weighing sensor is used to weigh the oil volume.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-6 In this embodiment of the present invention, a weighing-type metering spinning oil mixing tank includes an outer cylinder 10 and an inner cylinder 20 slidably installed inside the outer cylinder 10. The inner cylinder 20 is used to store spinning oil. A weighing assembly is provided between the outer cylinder 10 and the inner cylinder 20. The weighing assembly includes a top rod 30 and a weighing sensor 40. The top rod 30 is a telescopic rod structure, which can be an electric telescopic rod, a cylinder, or a hydraulic rod. In this embodiment, the top rod 30 is a hydraulic rod. The top rod 30 is fixedly installed on the inner wall of the outer cylinder 10 via a first support frame 31. The first support frame 31 has an opening, and a second support frame 41 is provided in the opening. The weighing sensor 40 is installed on the second support frame 41. A connecting rod 42 is fixedly installed at the bottom of the second support frame 41. A lifting control assembly 50 for controlling the lifting and lowering of the connecting rod 42 is provided on the inner wall of the outer cylinder 10. In the initial state, the top rod 30 is in a... In its extended state, the outer edge of the inner cylinder 20 rests on the top rod 30. At this time, the weighing sensor 40 is separated from the outer edge of the inner cylinder 20. When the spinning oil is injected into the inner cylinder 20 and needs to be weighed, the top rod 30 shortens, so that the outer edge of the inner cylinder 20 rests on the weighing sensor 40, and the outer edge of the inner cylinder 20 contacts the weighing sensor 40. The weighing sensor 40 weighs the inner cylinder 20 and the spinning oil inside the inner cylinder 20. Since the mass of the inner cylinder 20 is constant, the weight of the spinning oil can be obtained by subtracting the mass of the inner cylinder 20 from the weighed weight. In actual use, the spinning oil mixing tank has the function of storing the spinning oil. When the spinning oil needs to be stored for a long time, in order to avoid the weighing sensor 40 from contacting the outer edge of the inner cylinder 20 for a long time, the lifting control component 50 controls the weighing sensor 40 to descend, so that the outer edge of the inner cylinder 20 rests on the shortened top rod 30, and finally the weighing sensor 40 is separated from the outer edge of the inner cylinder 20.
[0023] In the embodiments of this application, such as Figure 5 As shown, the lifting control assembly 50 includes a slider 51, an electromagnet 53, and a tension spring 54. A groove is formed on the inner wall of the outer cylinder 10, and the slider 51 is slidably installed inside the groove. The electromagnet 53 is fixedly installed on the upper part of the groove. An iron block 52 is fixedly installed on the side of the slider 51 facing the electromagnet 53. When the load cell 40 weighs the inner cylinder 20, the electromagnet 53 is energized and attracts the iron block 52, causing the iron block 52 and the slider 51 to pull the tension spring 54. When it is necessary to control the load cell 40 to descend, the electromagnet 53 is de-energized. The iron block 52 and the slider 51 descend under the tension of the tension spring 54, thereby causing the load cell 40 to descend and disengage from the outer edge of the inner cylinder 20. It should be noted that the technical means of energizing and de-energizing the electromagnet 53 is existing technology and will not be described in detail here.
[0024] In this embodiment, a cover 11 is installed on the outer cylinder 10, and an oil inlet 12 is provided on the cover 11. The oil inlet 12 is used to inject spinning oil into the inner cylinder 20. An oil outlet 15 is provided at the bottom of the outer cylinder 10, and a connecting pipe 21 is connected to the bottom of the inner cylinder 20. The connecting pipe 21 is a retractable corrugated pipe structure, and the connecting pipe 21 is connected to the oil outlet 15. The connecting pipe 21 and the oil outlet 15 are used to discharge the spinning oil inside the inner cylinder 10.
[0025] In addition, in this embodiment, a plurality of brackets 13 for supporting the outer cylinder 10 are installed on the side of the outer cylinder 10; a mounting base 14 is also provided on the outer cylinder 10, the mounting base 14 is used to install a display screen, the display screen is electrically connected to the weighing sensor 40, and the display screen is used to display the weight of the spinning oil.
