[0002] Basalt fiber is a new type of inorganic, environmentally friendly, high-performance fiber material with excellent mechanical properties, high temperature resistance, corrosion resistance, and flame retardancy. It is widely used in aerospace, rail transportation, and building materials industries. Flame-retardant insulation boards are essential materials for ensuring the safe operation of electrical equipment.

[0003] In modern industry, basalt fiber, as a high-performance inorganic non-metallic material, is widely used in aerospace, automotive manufacturing, building materials, and electronics due to its excellent mechanical properties, high-temperature resistance, chemical stability, and good electrical insulation. Especially in the preparation of flame-retardant insulating materials, basalt fiber, with its natural flame-retardant properties and good insulation performance, has become an ideal raw material for manufacturing high-performance flame-retardant insulating boards.

[0004] However, in the manufacturing process of basalt fiber flame-retardant insulation boards, ensuring that the resin and other binders are mixed uniformly and efficiently with the basalt fibers, and effectively preventing external impurities from entering the mixing system after mixing, is one of the key factors affecting product quality and production efficiency. Traditional manufacturing equipment often uses simple conveying pipes and valves to control the resin delivery. This design has the following shortcomings: resin delivery and pipe sealing often require manual operation, which not only increases labor intensity but also makes it difficult to ensure the timeliness and accuracy of operation, affecting production efficiency. Therefore, a device for manufacturing basalt fiber flame-retardant insulation boards is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a device for manufacturing basalt fiber flame-retardant insulation boards, in order to solve the problem that resin transportation and pipeline sealing often require manual operation, which not only increases labor intensity but also makes it difficult to ensure the timeliness and accuracy of operation, thus affecting production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Connecting pipes and delivery pipes are respectively installed on both sides of the delivery pump. The apparatus also includes:

[0008] An automatic closing mechanism is used to automatically close the preparation tank after the delivery pump delivers resin into the tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] like Figure 1-4 As shown, an apparatus for manufacturing basalt fiber flame-retardant insulation boards includes a preparation tank 1, a vacuum pump body 2, a vacuum pump pipe 3, and a delivery pump 4. Connecting pipes 5 and delivery pipes 6 are respectively installed on both sides of the delivery pump 4. The apparatus also includes an automatic closing mechanism for automatically closing the preparation tank 1 after the delivery pump 4 delivers resin into the preparation tank 1. The automatic closing mechanism is installed on the outer wall of the preparation tank 1 and includes a feed pipe 7. A rotating shaft 701 is rotatably connected to one end of the feed pipe 7, and one end of the rotating shaft 701 extends rotatably to the outside of the feed pipe 7. A rotating plate 702 is fixedly connected to the outer wall of the rotating shaft 701 inside the feed pipe 7. A sealing strip 706 is provided on the outer wall of the rotating plate 702. A protective shell 703 is fixedly installed on the outer wall of the feed pipe 7. A fixed plate 704 is fixedly connected to the end of the rotating shaft 701 outside the feed pipe 7. A torsion spring 705 is connected to the inner side of the fixed plate 704.

[0023] The present invention is further described in detail as follows: the vacuum pump body 2 is installed on the preparation tank 1, the vacuum pump pipe 3 is installed on the vacuum pump body 2, one side of the feed pipe 7 is connected to the connecting pipe 5, and the interior of the connecting pipe 5 and the feed pipe 7 are connected; the outer wall of the sealing strip 706 is slidably fitted to the inner wall of the feed pipe 7; the bottom of the feed pipe 7 is inclined; the bottom of the sealing strip 706 extends to the inclined position at the bottom of the feed pipe 7 and is correspondingly pressed against the inclined position at the bottom of the feed pipe 7; the fixed plate 704 and the torsion spring 705 are both located inside the protective shell 703; the end of the torsion spring 705 away from the fixed plate 704 is connected to the outer wall of the feed pipe 7; the torsion spring 705 is sleeved on the outer wall of the rotating shaft 701; and the interior of the feed pipe 7 and the preparation tank 1 are connected.

[0024] As can be seen from the above, it should be noted that: a mold plate is provided inside the preparation tank 1, and the mold plate is correspondingly set with the feed pipe 7. The resin entering the preparation tank 1 falls onto the mold plate.

[0025] The preparation tank 1 is equipped with a heating plate inside for heating the inside of the preparation tank 1, and a control panel is equipped on the outside of the preparation tank 1 for monitoring the heating temperature.

[0026] Before the device is started, all components are in the initial state. The delivery pump 4 is in the off state, there is no resin flow inside the connecting pipe 5 and the feed pipe 7, and the rotating plate 702 is in the closed position under the action of the torsion spring 705, that is, the rotating plate 702 and the internal channel of the feed pipe 7 form a seal to prevent outside air or impurities from entering the preparation tank 1;

[0027] When resin needs to be delivered into the preparation tank 1, the delivery pump 4 is started. The delivery pump 4 draws resin from the external resin storage tank through the connecting pipe 5. The resin enters the feed pipe 7 along the connecting pipe 5. As the resin flows in, it exerts a certain pressure on the rotating plate 702. However, since the bottom of the feed pipe 7 is designed to be inclined, the resin flow exerts pressure on the rotating plate 702 to open it, thereby opening the channel of the feed pipe 7 and allowing the resin to flow smoothly into the interior of the preparation tank 1. During this process, the vacuum pump 2 works continuously through the vacuum pump pipe 3 to maintain the vacuum state inside the preparation tank 1, which helps to quickly and evenly fill the resin and remove air from the tank, thereby improving product quality.

[0028] When the resin delivery volume reaches the preset value or the delivery is completed as determined by an external control signal, the delivery pump 4 stops working, and the resin flow stops. As the resin pressure in the feed pipe 7 decreases, the reset force of the torsion spring 705 begins to play a dominant role, driving the rotating shaft 701 to rotate the rotating plate 702 in the opposite direction until the rotating plate 702 forms a seal with the internal channel of the feed pipe 7 again. The tight fit between the sealing strip 706 and the inner wall of the feed pipe 7, as well as the top pressure setting of the bottom of the sealing strip 706 and the inclined position at the bottom of the feed pipe 7, ensure the reliability of the seal and effectively prevent the entry of external air or impurities. The design of the protective shell 703 not only protects key components such as the rotating shaft 701, the fixed plate 704, and the torsion spring 705 from the influence of the external environment, but also ensures the stability and durability of the torsion spring 705 during the reset process.

[0029] By setting up the above technical solution, the rotating shaft 701, rotating plate 702 and torsion spring 705 can cooperate to make the rotating plate 702 automatically open and close as the resin flows in. At the same time, based on the function of the sealing strip 706, the inside of the preparation tank 1 is sealed. Compared with the manual operation required for resin transportation and pipeline sealing, this not only reduces labor intensity, but also ensures the timeliness and accuracy of operation and improves production efficiency.

[0030] After the resin is delivered, the basalt fiber and resin in the preparation tank 1 are fully mixed on the mold plate in a vacuum environment. After subsequent processing steps such as curing and molding, the basalt fiber flame-retardant insulation board is finally produced. It should be noted that the preparation operation after the resin is delivered is existing technology, and its working principle will not be described in detail.

[0031] Furthermore, this design is applied to the manufacture of basalt fiber flame-retardant insulation boards. By utilizing the cooperation between the rotating shaft 701, the rotating plate 702, and the torsion spring 705, the rotating plate 702 can automatically open and close as the resin flows in. At the same time, based on the function of the sealing strip 706, the interior of the preparation tank 1 is sealed. Compared with the manual operation required for resin transportation and pipeline sealing, this not only reduces labor intensity but also ensures the timeliness and accuracy of operation, thereby improving production efficiency.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
