Description

Technical Field

[0001] The invention relates to the technical field of liquid level automatic control, in particular to an automatic liquid level control device for a glass fiber sizing agent. Background Art

[0002] Glass fiber sizing is an important chemical substance derived from the concept of "wetting" in physics. It plays a vital role in the production and application of glass fiber. Sizing is a multi-component aqueous solution or emulsion composed of water or organic solvent as medium and binder, coupling agent, surfactant, antistatic agent, etc. as solute. In glass fiber processing, glass needs to be immersed in glass fiber sizing. The liquid level automatic control device is used to control the liquid level of glass fiber sizing to ensure that the glass fiber is immersed in the glass fiber sizing.

[0003] A Chinese patent discloses an automatic control device for the liquid level of glass fiber sizing agent (Announcement No. CN203259892U). This patented technology realizes the real-time control of the liquid level of the sizing agent in the water tank accurately and efficiently through the water tank that automatically controls the liquid level, and also reduces the labor intensity of workers. However, the above-mentioned automatic control device for the liquid level of glass fiber sizing agent detects the liquid level of glass fiber sizing agent through an immersion liquid level sensor. Since the glass fiber sizing agent is relatively thick, it affects the accuracy of the liquid level detection, which is not conducive to the subsequent liquid level control operation. The liquid level is adjusted directly by the operation of the liquid pump. When the glass fiber is added again after adjustment, it will affect the liquid level height. The flexibility of the liquid level control is low, which is not conducive to the accuracy of the liquid level control.
