Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber production equipment, and particularly relates to an anti-overflow liquid retaining tank. Background Art

[0002] Patent document CN116332529A (June 27, 2023) discloses an external spraying device for glass fiber antistatic agent. The principle is to atomize the antistatic agent by using a pneumatic atomizing nozzle and spray it onto the glass fiber bundle, and then use an oil mist reflector to reflect the unabsorbed antistatic agent oil mist and spray it onto the glass fiber bundle for the second time. This method makes the spraying rate and retention rate of the antistatic agent on the glass fiber bundle close to 100%, thereby improving the product quality of the glass fiber.

[0003] The oil mist reflector is one of the core components of the above spraying device, and has a reflection groove consistent with the moving direction of the glass fiber bundle. The notch of the reflection groove faces the atomizing nozzle assembly, and the reflection groove also forms a guide groove for the axial movement of the glass fiber bundle. When the glass fiber is oiled, part of the antistatic agent sprayed by the pneumatic atomizing nozzle is directly sprayed onto the glass fiber; part of it is reflected by the guide groove and sprayed onto the glass fiber for the second time; part of it accumulates in the guide groove to form a liquid level with a certain height, and then is taken away by the moving glass fiber; in addition, a small amount overflows from both ends of the guide groove. For this part of the antistatic agent that overflows, a liquid collecting box is arranged below the oil mist reflector of the spraying device, and is communicated with the container assembly through an oil return groove or an oil return hole to realize the recovery of the antistatic agent.

[0004] In the above spraying device, a special antistatic agent recovery device needs to be set up, and the overflowing antistatic agent will inevitably splash during the falling process, resulting in waste and pollution to the external environment. Therefore, users expect to develop an oil mist reflector with zero liquid overflow. Summary of the Utility Model

[0005] In order to prevent the antistatic agent from overflowing from both ends of the guide groove of the glass fiber bundle, the utility model provides an anti-overflow liquid retaining tank.

[0006] The technical solution adopted by the utility model is as follows: an anti-overflow liquid retaining tank includes a guide block body, an axially penetrating guide groove is opened on the upper surface of the guide block body, and partition grooves are arranged on the surfaces of both ends of the guide groove of the guide block body, and the partition grooves extend from one side of the notch of the guide groove to the other side.

[0007] Preferably, the partition groove is arranged perpendicular to the axis of the guide groove.

[0008] Preferably, at least two partition grooves are arranged at each end of the guide groove.

[0009] Preferably, the openings of the guiding groove and the partition groove are both rounded.

[0010] Preferably, an inclined connecting surface is provided between the two side openings of the guiding groove and the upper surface of the guiding block body.

[0011] Preferably, the width of the partition groove is greater than its depth.

[0012] The utility model has the following beneficial effects: The utility model is provided with partition grooves at both ends of the guiding groove. The existence of the partition grooves changes the contact angle between the antistatic agent and the guiding groove, making the antistatic agent generate more obvious bending and protrusions in the guiding groove by surface tension, forming a higher liquid level, temporarily storing a higher liquid level and a larger volume of antistatic agent, that is, improving the accumulation and retention performance of the antistatic agent in the guiding groove; The accumulated antistatic agent adheres to the fast-moving glass fiber bundle and is carried away, basically preventing the antistatic agent from overflowing from both ends of the guiding groove, reducing the waste caused by the splashing of the antistatic agent, protecting the working environment, and reducing the maintenance and cleaning work of the equipment; In addition, the antistatic agent recovery device can be omitted, simplifying the equipment structure.

[0014] Figure 2 It is an enlarged schematic diagram of part A in the embodiment of the utility model.

[0015] Guiding block body 1, guiding groove 2, partition groove 3, inclined connecting surface 4. Detailed Embodiment

[0016] The following further illustrates the utility model in conjunction with the embodiments and the drawings.

[0017] In the embodiment, as Figure 1 、 2 shown, it is an anti-overflow liquid retaining groove, including a guiding block body 1. An axially penetrating guiding groove 2 is formed on the upper surface of the guiding block body 1. Partition grooves 3 are provided on the surfaces of the guiding block body 1 at both ends of the guiding groove 2, and the partition grooves 3 extend from one side of the opening of the guiding groove 2 to the other side. In this embodiment, partition grooves 3 are provided at both ends of the guiding groove 2. The existence of the partition grooves 3 changes the contact angle between the antistatic agent and the guiding groove 2, making the antistatic agent generate more obvious bending and protrusions in the guiding groove 2 by surface tension, forming a higher liquid level, temporarily storing a higher liquid level and a larger volume of antistatic agent, that is, improving the accumulation and retention performance of the antistatic agent in the guiding groove 2; The accumulated antistatic agent adheres to the fast-moving glass fiber bundle and is carried away, basically preventing the antistatic agent from overflowing from both ends of the guiding groove 2, reducing the waste caused by the splashing of the antistatic agent, protecting the working environment, and reducing the maintenance and cleaning work of the equipment; In addition, the antistatic agent recovery device can be omitted, simplifying the equipment structure.

[0018] In the embodiment, as Figure 1 , 2 shown, the partition groove 3 is arranged perpendicular to the axis of the guide groove 2, and at least two partition grooves 3 are arranged at both ends of the guide groove 2. The multiple partition grooves 3 play a role of multiple liquid blocking, can further improve the accumulation and retention performance of the antistatic agent in the guide groove 2, and thus further prevent the overflow of the antistatic agent.

[0019] In the embodiment, as Figure 1 , 2 shown, the openings of the guide groove 2 and the partition groove 3 are both rounded. The rounded corners of the guide groove 2 and the partition groove 3 can prevent the glass fiber bundle from being scratched. The rounded corner of the partition groove 3 can also reduce the contact angle and improve the stability of the antistatic agent in the partition groove 3, so as to better keep the liquid in the partition groove 3 and improve the accumulation and retention performance of the antistatic agent in the guide groove 2.

[0020] In the embodiment, as Figure 1 , 2 shown, an inclined connecting surface 4 is provided between the two side openings of the guide groove 2 and the upper surface of the guide block body 1. The inclined connecting surface 4 can make the redundant antistatic agent splashed on other positions of the guide block body 1 flow back into the guide groove 2, avoiding waste.

[0021] In the embodiment, as Figure 1 , 2 shown, the width of the partition groove 3 is greater than the depth. The wider partition groove 3 can also improve the accumulation and retention performance of the antistatic agent in the guide groove 2, and is also convenient for cleaning the partition groove 3.

[0022] Obviously, the above embodiments of the present invention are only examples for explaining the present invention, rather than limiting the implementation manners of the present invention. Other obvious changes or variations derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
