Description

Technical Field

[0001] The invention relates to the technical field of basalt fiber preparation, and in particular to a basalt fiber high-efficiency energy-saving drying device and a drying process. Background Art

[0002] Basalt fiber: continuous fiber drawn from natural basalt. It is a continuous fiber drawn at high speed through a platinum-rhodium alloy wire drawing plate after the basalt material is melted at 1450℃~1500℃. The color of pure natural basalt fiber is generally brown. Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide and titanium dioxide. Basalt continuous fiber not only has high strength, but also has many excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance.

[0003] During the preparation of basalt fiber, the processed product needs to be dried. For example, a basalt fiber softening, drying and conveying device proposed in 202221674010.X has the advantages of efficient drying and transmission. In actual use, through the coordinated use of combed fiber curtain transmission mechanism, corner nail curtain transmission mechanism, flat curtain transmission mechanism, heating pipe, placement plate, power assembly, transmission assembly, adjustment assembly and drying assembly, it plays the role of transporting and evenly drying the processed product, which not only effectively performs softening, desensitizing, drying and transmission, but also reduces the difficulty of the next processing step.

[0004] However, traditional basalt fiber drying equipment mostly uses electric heating for drying. During the electric heating process, it absorbs the moisture content of the air inside the drying equipment, causing the basalt fiber to produce a large amount of static electricity, causing mutual adhesion, and during the transmission process, a large amount of basalt fiber will accumulate, resulting in low drying efficiency and too much time required for drying. This paper proposes a basalt fiber high-efficiency and energy-saving drying device and drying process to solve the above problems. Summary of the invention

The external tap water pipe enters into the connecting box 704 through the water inlet pipe installation hole. The circulation pipe 706 is interconnected with the heat-conducting pipe 703, and the heater 708 is arranged at an upper position inside the supporting frame 702.

[0038] Specifically, the external water pipe is fixed to the connecting flange 705, and water flows to the right from the heat pipe 703 and the circulation pipe 706. A number of heaters 708 are started to heat the flowing water. The heating will cause the water to heat up rapidly.

[0039] Please refer to Figure 5 The conveyor belt 4 is on the left side of the push port 9. The basalt fiber raw material conveyed by the conveyor belt 4 will fall onto the mesh plate 11 from the push port 9. The mesh plates 11 are designed with three mesh plates, which are installed in a stepped manner up and down inside the base 2. The inner bottom wall of the base 2 is designed to be inclined, so that the dried basalt fiber raw material can slide to the discharge seat 3 for discharge.

[0040] In this embodiment, the pulley 102 is rotatably installed inside the installation cavity 13, the pulley 102 is installed at both ends of the driving rod B114 and the driving rod C115, the active bevel gear 105 and the driven bevel gear 103 are meshed with each other, the rotating shaft 106 is rotatably installed on the right side of the partition 12, a rotating opening is opened on the support plate 108, and the driving rod A101, the driving rod B114 and the driving rod C115 are rotatably installed inside the rotation, the end of the electric push rod 113 away from the support plate 108 is in contact with the driving wheel 110, the driving rod A101, the driving rod B114 and the driving rod C115 are all connected by the transmission belt B111, the slots 116 are arranged in an equidistant ring, and the limit blocks 112 are inserted into the corresponding slots 116.

[0041] Specifically, the driving motor 104 will drive the driving rod 101 to rotate, and the driving rod 101 will drive the rotating shaft 106 to rotate through the transmission belt A107, so that the mesh plate 11 will swing up and down around the rotating shaft 106 to turn the basalt fiber raw material. The driving rod A101, the driving rod B114 and the driving rod C115 will rotate in sequence through the transmission belt B111 to realize multi-level turning and drying. Finally, the dried basalt fiber raw material will be discharged from the discharge seat 3.

[0042] Please refer to Figure 6-9 When the driving motor 104 drives the driving rod A101, the driving rod B114 and the driving rod C115 to rotate, the driving motor 104 drives the driving rod A to rotate under the cooperation of the active bevel gear 105 and the driven bevel gear 103. The driving rod A rotates and drives the rotating shaft 106 to rotate through the transmission belt A107, driving the uppermost screen plate 11 to swing;

[0043] Secondly, the electric push rods 113 on the driving rods A101 and B114 simultaneously push the driving wheel 110 to move inward, and the limit block 112 is inserted into the corresponding slot 116. At this time, the driving wheel 110 will be stuck on the outer surface of the driving rod A101, and the driving rod A101 rotates to drive it to rotate, and the driving rod B114 is driven to rotate through the transmission belt B, and the driving rod B114 drives the middle screen 11 to rotate;

[0044] Finally, the driving rod B114 drives the driving rod C115 to rotate through the above steps, so that the bottom mesh plate 11 swings, and the mesh plates 11 swing in sequence, so that the basalt fiber raw materials can be transported to different positions and dispersed by swinging, and the multi-level dispersion accelerates the drying speed.

[0045] In summary, the present invention heats the downwardly blowing wind through the heat emitted by the heat pipe 703 and then dries it. After the water inside the heat pipe 703 is heated, it can maintain heat for a period of time, and does not need to be continuously heated by the heater. Moreover, the heated water can be recycled, avoiding the waste of circuit resources caused by continuous heating. In addition, the water conducts heat to avoid a large amount of evaporation of water in the air, so that the interior of the shell 5 will not be excessively dry, and it is not easy to generate static electricity to cause the basalt fiber raw materials to adsorb and accumulate on each other, thereby improving the drying efficiency and saving energy and being environmentally friendly. The basalt fiber raw materials accumulated during the transmission process are dispersed by swinging up and down by multiple mesh plates 11, and they can jump up. During the drying process, the hot air can better contact the basalt fiber raw materials, complete the drying operation faster, improve the drying efficiency, and reduce energy consumption.
