Description

Technical Field

[0001] The utility model relates to the technical field of quartz fiber processing, in particular to a quartz fiber impregnation agent circulation system. Background Art

[0002] As a high-performance material, quartz fiber is widely used in aerospace, electronics, chemical engineering, and other fields. To enhance the strength, flexibility, durability, and high-temperature resistance of quartz fiber, it is typically coated with a sizing. During the quartz fiber production process, the sizing primarily lubricates the fiber and promotes fiber bundling, thereby improving its spinnability. It also enhances its bonding with matrix materials such as resin, thereby enhancing the mechanical properties and durability of the final product.

[0003] However, existing sizing agent circulation systems suffer from low efficiency, poor uniformity, and a low degree of automation. Currently, most quartz fiber sizing agent mixing tanks still rely on manual addition of sizing agent, a process that not only consumes significant manpower and material resources but also can lead to risks such as abnormal liquid levels due to operator negligence. Furthermore, due to the varying composition of sizing agents used in quartz fiber processing, the processing techniques are also diverse. Consequently, different requirements exist for the stirring and output rates of the sizing agent, placing greater demands on the automation of the sizing agent mixing tank and circulation system to enhance its controllability.

[0004] In view of the above problems, a quartz fiber impregnation agent circulation system is now designed. Summary of the Invention

[0005] The purpose of the utility model is to provide a quartz fiber sizing agent circulation system which is efficient, uniform and easy to operate, so as to solve the problems raised in the prior art.

[0006] In order to achieve the above-mentioned purpose of the invention, the present invention provides the following technical solutions:

[0007] A quartz fiber sizing agent circulation system includes a circulating stirring tank, a filter, a centrifugal pump and an oiler. The circulating stirring tank is provided with a discharge port and a return port. The discharge port, the centrifugal pump and the oiler are connected by a pipeline. A filter is provided between the centrifugal pump and the oiler. The oiler and the return port are connected by a pipeline. A filter is provided between the return port and the oiler. The circulating stirring tank is also provided with a stirring motor, a stirring shaft and stirring blades. The stirring motor drives the stirring shaft and the stirring blades to rotate. The stirring blades are spirally arranged along the length direction of the stirring shaft.

[0008] As a preferred solution, the circulating stirring tank includes a tank body and a tank cover, a feeding port is provided on the top of the tank cover, a stirring motor is fixed to the tank body, a stirring shaft is provided inside the tank body; and a discharging port is provided at the bottom of the tank body.

[0009] As a preferred solution, a liquid level gauge is provided inside the tank body and an overflow port is provided on the side of the tank body. The liquid level gauge monitors the liquid level in the tank body in real time. When the liquid level in the tank body is lower than the preset minimum liquid level, the wetting agent is stopped from being output from the tank body. When the liquid level in the tank body is higher than the preset maximum liquid level, the overflow port is opened to discharge excess wetting agent from the overflow port.

[0010] As a preferred solution, the oil applicators are at least two groups.

[0011] As a preferred solution, a control module is also included for uniformly controlling the stirring motor, liquid level meter, overflow port, centrifugal pump and filter.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] The utility model provides a quartz fiber sizing agent circulation system, comprising the following parts:

[0020] Circulating Mixing Tank: This consists of a cover, a tank body, and supporting legs. The tank body is made of high-temperature and corrosion-resistant materials, including but not limited to PP, PTFE, and PU. It is used to contain the wetting agent and ensure its chemical stability during the mixing process. The size of the circulating mixing tank is designed according to actual production needs, generally with a diameter of 1000mm and a height of 1500mm.

[0021] Filter: It is installed between the discharge port of the circulating stirring tank and the oiler, as well as between the reflux port and the oiler, and is used to filter out impurities and incompletely mixed particles in the wetting agent to ensure the purity of the wetting agent.

[0022] Stirring Assembly: This system consists of a stirring motor, stirring shaft, and stirring blades, ensuring thorough mixing of the infiltrant components and improving mixing uniformity. The stirring blades are arranged spirally along the length of the stirring shaft to enhance stirring efficiency and uniformity. The interior is constructed of 304 stainless steel and coated with PTFE. The stirring motor is controlled by a frequency converter, enabling precise adjustment of the stirring speed.

[0023] Liquid level control assembly: This includes a level gauge and overflow port, used to monitor and control the level of the impregnating agent in the circulating mixing tank. When the level falls below the preset minimum level, the system will alarm and stop the impregnating agent output. When the level reaches the preset maximum level, the overflow port will automatically open to drain excess impregnating agent, preventing spillage and protecting the equipment from damage.

[0024] Discharge and Reflux System: This system, controlled by a centrifugal pump, accurately delivers the sizing agent to the two oiler systems and, when needed, refluxes some of the sizing agent back into the circulating agitator tank via gravity flow, thereby achieving sizing agent circulation. The pump is constructed of corrosion-resistant materials to accommodate the chemical characteristics of the sizing agent components.

[0025] The self-cleaning system, which includes automatic cleaning nozzles and a circulation pump, automatically cleans the circulating mixing tank, filtration system, and mixing components after the sizing process is complete. The circulation pump delivers cleaning fluid to all components, while the automatic cleaning nozzles evenly distribute the fluid, ensuring no residue remains inside the equipment. This reduces the tedious task of manual cleaning and improves production efficiency.

[0026] Automatic control system: Through the PLC control module, centralized control of each system is achieved, improving the convenience of operation and the degree of automation of the processing process.

[0027] When using this device to process quartz fiber sizing, the sizing is first piped from the preparation room to the inlet, then into the circulating agitator tank, where the agitator assembly is activated for mixing. The agitated sizing is then discharged through the outlet and filtered through a filter to remove impurities and particles. The discharged sizing is then piped through two oiler systems. Finally, excess sizing after use in the drawing process is returned to the circulating agitator tank through the filter and reflux port.

[0028] like Figure 1-3 As shown, a quartz fiber sizing agent circulation system includes a tank body 1, a stirring motor 2, a tank cover 3, a feeding port 4, a stirring shaft 5, a stirring blade 6, a feeding port 7, a reflux port 8, a liquid level meter 9, an overflow port 10, a centrifugal pump 11, a filter 12, and a PLC control module 13.

[0029] Tank 1 is a container for quartz fiber sizing, with a lid 3 on top. A feed inlet 4 is located at the top of lid 3. A stirring motor 2 is fixed to tank 1, with its output connected to a stirring shaft 5. This stirring shaft 5 is located inside tank 1, and a stirring blade 6 is fixed to this shaft. A discharge port 7 is located at the bottom of tank 1, and a return port 8 is located on the side. A liquid level gauge 9 is located within tank 1, and an overflow port 10 is located on the side. The discharge port 7 is connected to a centrifugal pump 11 and a filter 12, and the return port 8 is also connected to the filter 12.

[0030] During operation, the tank cover 3 is opened and the wetting agent is sequentially added into the tank body 1 through the feed port 4. The stirring assembly is started, and the stirring shaft 5 and the stirring blade 6 are driven by the stirring motor 2 to rotate at a set speed to fully mix the various components of the wetting agent and achieve uniform distribution.

[0031] During the actual operation of the system, the liquid level meter 9 monitors the liquid level in the tank body 1 in real time. When the liquid level in the tank body 1 is lower than the preset minimum liquid level, an alarm is triggered and the output of the wetting agent from the tank body 1 is stopped. When the liquid level in the tank body 1 is higher than the preset maximum liquid level, an alarm is triggered and the overflow port 10 is opened to discharge the excess wetting agent from the tank body 1. The centrifugal pump 11 outputs the wetting agent through the discharge port 7 and filters the wetting agent through the filter 12. The output wetting agent passes through two sets of oiler systems through the pipeline. In this embodiment, two sets of oiler systems are selected. Those skilled in the art can also set up one or more sets of oiler systems as needed. They only need to increase the pipelines and filters accordingly. The last part of the unused wetting agent flows back to the tank body 1 from the reflux port 8 after passing through the filter 12 by its own gravity.

[0032] The system centrally controls the stirring motor 2, liquid level gauge 9, overflow port 10, centrifugal pump 11, and filter 12 through a PLC control module 13. For example, for sizing agents that easily foam, the PLC control module can reduce the stirring rate to minimize foaming; while for processes that require a higher sizing agent supply speed, the PLC control module can increase the discharge speed.
