Abstract
Description
Technical Field
[0001] This utility model relates to the field of short fiber drawing technology, and in particular to an automatic defoamer dripping device for short fiber drawing. Background Technology
[0002] In the production process of short fiber drawing lines, oil agents, such as JX-98 and CE-1, can be sprayed to reduce friction and static electricity. During the use of the oil agent, the rapid operation of the drawing rollers, the circulation pumping of the oil agent, and the spraying impact will all cause the oil agent to be violently agitated, drawing in a large amount of air and breaking it down into foam.
[0003] Foam in the oiling agent can lead to uneven oiling of the fibers, affecting their smoothness, bundling, and subsequent spinnability. Furthermore, excessive foam can cause overflow in the oiling tank, forcing a shutdown for cleaning and disrupting production continuity. Foam overflow also results in oiling agent loss, increasing production costs. To eliminate foam in the oiling agent, a small amount of prepared defoamer can be sprayed using a sprayer to impact the foam layer; however, this method is inefficient, and if spraying is not timely under pressure, overflow may occur. Utility Model Content
[0004] The main technical problem solved by this utility model is to provide an automatic defoamer dripping device for short fiber drawing, which eliminates foam in the oil storage tank and improves the level of automation.
[0005] To solve the above-mentioned technical problems, the present invention provides an automatic dripping device for defoamer used in short fiber drawing, comprising: a lifting frame, a defoamer container, a dripping tube, a valve, a first liquid level sensor, and a second liquid level sensor. The defoamer container is mounted on the lifting frame, the dripping tube is mounted on one side or the bottom of the defoamer container, the valve is mounted on the dripping tube, the first liquid level sensor is suspended on one side of the dripping tube to monitor the liquid level below the dripping tube, and the second liquid level sensor is suspended above the defoamer container to monitor the liquid level in the defoamer container.
[0006] In a preferred embodiment of this invention, the opening of the dropper points downwards.
[0007] In a preferred embodiment of this utility model, a crossbeam is provided on the top of the defoamer container, and the second liquid level sensor is vertically mounted on the crossbeam.
[0008] In a preferred embodiment of the present invention, the lifting frame includes a base, a mounting plate, a guide sleeve, and a guide rod. The guide sleeve is vertically disposed on the base, the guide rod is concentrically disposed in the guide sleeve and extends upward, the mounting plate is horizontally disposed on the top of the guide rod, and the defoamer container is disposed on the mounting plate.
[0009] In a preferred embodiment of this utility model, the first liquid level sensor is vertically mounted on the mounting plate.
[0010] In a preferred embodiment of this utility model, a screw pointing to the guide rod is provided on one side of the guide sleeve.

[0012] The beneficial effects of this utility model are as follows: The automatic defoamer dripping device for short fiber drawing disclosed in this utility model allows the lifting frame to be placed in the oil storage tank and its position adjusted so that the dripping pipe is positioned above the foam concentration area in the oil storage tank. The defoamer in the defoamer container drips downwards into the foam concentration area through the dripping pipe for concentrated defoaming. The valve opening is adjusted according to the defoaming effect to ensure the defoaming effect, save defoamer, and reduce costs. The first liquid level sensor can be used to monitor the foam liquid level to avoid the problem of oil foam overflowing due to untimely defoaming.

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0017] Please see Figures 1-2 The embodiments of this utility model include:
[0018] An automatic defoamer dispensing device for short fiber drawing includes: a lifting frame, a defoamer container 6, a dispensing tube, a valve 8, a first liquid level sensor 10, and a second liquid level sensor 7. The defoamer container 6 is mounted on the lifting frame and can be a stainless steel can with an open top, which has good corrosion resistance and a long service life.
[0019] In this embodiment, the lifting frame includes a base 1, a mounting plate 5, a guide sleeve 2, and a guide rod 4. The guide sleeve 2 is vertically mounted on the base 1 and can be welded and fixed, resulting in a robust structure. The guide rod 4 is concentrically mounted in the guide sleeve 2 and extends upwards, facilitating height adjustment.
[0020] The mounting plate 5 is horizontally positioned on top of the guide rod 4, and the defoamer container 6 is mounted on the mounting plate 5 and fixed by welding or screws. The structure is stable, allowing the height of the defoamer container 6 to be adjusted as the guide rod 4 extends and retracts to adapt to the liquid level of the oil foam in the oil storage tank.
[0021] The dripping tube 9 is positioned on one side or at the bottom of the defoamer container 6, and the valve 8 is mounted on the dripping tube 9 to control the dripping amount. The opening of the dripping tube 9 points downwards, dripping into the lower foam concentration area. The lifting frame can be placed in the oil storage tank and adjusted so that the dripping tube 9 is positioned above the foam concentration area in the oil storage tank. The defoamer in the defoamer container 6 drips downwards into the foam concentration area through the dripping tube 9 for concentrated defoaming. The opening of the valve 8 can be adjusted according to the defoaming effect to ensure the defoaming effect, which helps to save defoamer and reduce costs.
[0022] like Figure 1 As shown, in this embodiment, a screw 3 pointing to the guide rod 4 is provided on one side of the guide sleeve 2. The guide rod 4 is fixed after being adjusted by the screw 3, and the structure is stable.
[0023] like Figure 2 As shown, in this embodiment, a hydraulic cylinder 11 and a connecting plate 12 are also included. The connecting plate 12 is horizontally arranged between two adjacent guide sleeves 2 and can be welded and fixed. The hydraulic cylinder 11 is vertically arranged on the mounting plate 5 and connected to the connecting plate 12. The extension and retraction of the hydraulic cylinder 11 can be controlled by a PLC and a solenoid valve to change the position and height of the mounting plate 5 and the defoamer container 6 to adapt to the liquid level of the oil foam in the oil storage tank.
[0024] The first liquid level sensor 10 is suspended on one side of the dripping tube 9 to monitor the liquid level below the dripping tube 9. The first liquid level sensor 10 is connected to the PLC to send signals. When the oil foam liquid level rises, the PLC issues an alarm, which helps the operator to promptly detect problems and adjust the opening of the valve 8, thus improving the level of automation. Specifically, the first liquid level sensor 10 is vertically mounted on the mounting plate 5 and fixed by threads, ensuring structural stability.
[0025] The second liquid level sensor 7 is suspended above the defoamer container 6 to monitor the liquid level in the container. In this embodiment, a crossbeam 13 is provided on the top of the defoamer container 6, and the second liquid level sensor 7 is vertically mounted on the crossbeam 13, facilitating assembly. The second liquid level sensor 7 can be connected to a PLC to send signals. When the liquid level in the defoamer container 6 is too low, an alarm is triggered by a light or a buzzer, which facilitates timely manual addition of defoamer.
[0026] In summary, the automatic defoamer dripping device for short fiber drawing disclosed in this utility model can be built into the oil storage tank to automatically drip the defoamer, thereby improving the level of automation and meeting the needs of continuous production of short fiber drawing.
[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
