Description

A temperature control system for basalt fiber production Technical Field

[0001] This utility model relates to the field of basalt fiber production, specifically to a temperature control system for basalt fiber production. Background Technology

[0002] Basalt is a volcanic rock formed from magma erupting from volcanoes or seeping from fissures on the Earth's surface and solidifying. Continuous basalt fiber is made from basalt as raw material. The basalt is crushed and added to a melting furnace, melted at 1450-1500℃, and then drawn into continuous fibers through a stencil. Basalt fiber possesses excellent properties such as acid and alkali resistance, radiation resistance, high strength, and high modulus. Therefore, basalt fiber can be widely used in aerospace, military, automotive and shipbuilding manufacturing, engineering plastics, and construction industries.

[0003] Basalt fiber production involves a continuous process of melting and drawing. The quality of basalt ore melting directly affects the basalt drawing process. Basalt melting typically involves heating the basalt with electrodes to form a molten glass before drawing. Due to the poor thermal conductivity of molten basalt, most of the heat generated by the electrodes is located within a radius of 10 times the electrode, resulting in uneven heating. The energy from the electric heating takes a long time to be conducted to the temperature measuring point, which is detrimental to temperature control and easily leads to poor product quality. Furthermore, the lack of temperature control during the basalt fiber drawing process makes it impossible to guarantee the drawing effect of the basalt fiber.

[0004] Therefore, we propose a temperature control system for basalt fiber production. Summary of the Invention

[0005] The purpose of this invention is to provide a temperature control system for basalt fiber production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The power regulator includes a first power regulator and a second power regulator. The thermocouples include a first thermocouple and a second thermocouple. The furnace includes several heating zones, each with several electrodes. The electrodes are electrically connected to current transformers, which are electrically connected to electrofusion transformers. The electrofusion transformers are electrically connected to the first power regulator, which is electrically connected to the PLC controller.

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.

[0014] Referring to Figure 1, this embodiment provides a temperature control system for basalt fiber production, including a PLC controller, a power regulator, thermocouples, a furnace, and a drawing spindle. The power regulator includes a first power regulator and a second power regulator. The thermocouples include a first thermocouple and a second thermocouple. The furnace includes several heating zones, each equipped with multiple electrodes. This increases the radiation range of the electrode heat, ensuring uniform heating of the basalt melt. In this embodiment, the basalt fiber is heated in three stages: a melting stage, a homogenization stage, and a drawing stage. Each of these stages constitutes a heating zone. The furnace includes the heating zones for the melting and homogenization stages, and the drawing spindle includes the heating zone for the drawing stage.

[0015] Specifically, the electrodes are electrically connected to a current transformer, which is electrically connected to an electrofusion transformer. The electrofusion transformer is electrically connected to a first power regulator, which is electrically connected to a PLC controller. A first thermocouple is electrically connected to the PLC controller and is inserted into the basalt molten metal inside the furnace to measure the temperature of the molten basalt in real time. The temperature data from the first thermocouple can be transmitted to the PLC controller in real time. In actual production, due to the uneven temperature distribution inside the furnace, multi-point temperature measurement is required, such as at the furnace top, furnace walls, and molten pool.

[0016] Specifically, the first thermocouple feeds back the measured temperature data to the PLC controller in real time. The current transformer detects the current of the electrode and feeds back the current information to the PLC controller. The PLC controller adjusts the output power based on the feedback information and controls the output current of the first power regulator. By controlling the current, the temperature of the electrode is controlled, thereby controlling the temperature of the basalt melt in each heating zone of the furnace. The temperature of the basalt melt is controlled within a suitable range, that is, the temperature fluctuation is controlled within ±5℃, so as to provide uniform and impurity-free basalt melt for the next wire drawing operation.

[0017] Specifically, the second power regulator is electrically connected to the PLC controller, and is also electrically connected to a basalt plate transformer. The basalt plate transformer is electrically connected to the electrodes of the wire-drawing basalt plate. The second thermocouple is also electrically connected to the PLC controller and is mounted on the wire-drawing basalt plate for real-time temperature measurement. The temperature data from the second thermocouple can be transmitted to the PLC controller in real time. In this embodiment, the wire-drawing basalt plate is a conventional wire-drawing basalt plate, which will not be described in detail here.

[0018] Specifically, the second thermocouple feeds back the measured temperature data to the PLC controller in real time. The PLC controller adjusts the output power based on the feedback information and controls the output current of the second power regulator. By controlling the current, the temperature of the drawing die electrode is controlled to ensure the drawing effect of basalt fiber.

[0019] Specifically, in this embodiment, a molybdenum electrode is used. The molybdenum electrode can be wetted by basalt melt, has low contact resistance, and its surface can withstand high current density with low heat loss.

[0020] Specifically, the PLC controller is equipped with a touch screen, and the relevant parameters of the PLC controller can be viewed or set on the touch screen.

[0021] Specifically, the working principle of this utility model is as follows: For the furnace, the first thermocouple feeds back the temperature data to the PLC controller in real time, the current transformer detects the current of the electrode and feeds back the current information to the PLC controller, and the PLC controller controls the output current of the first power regulator according to the feedback information, thereby controlling the temperature of the electrode by controlling the current; For the wire drawing stencil, the second thermocouple feeds back the temperature data to the PLC controller in real time, and the PLC controller controls the output current of the second power regulator according to the feedback information, thereby controlling the temperature of the wire drawing stencil electrode by controlling the current.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
