Description

Technical Field

[0001] This utility model relates to the field of basalt fiber material product processing technology, and in particular to a device for accelerating the dehydration of wet basalt fiber material products. Background Technology

[0002] Continuous basalt fiber is made from volcanic rock, which is melted at a high temperature of 1450~1500℃ and then drawn into basalt wires through a platinum-rhodium alloy spinneret. The drawn basalt wires are then coated with a suitable sizing agent and wound into continuous basalt fiber.

[0003] Continuous basalt fibers are processed into basalt fiber cloth, felt and other products through processes such as chopping, weaving and needle punching. In actual use, cloth, felt and other products are usually combined with different types of resins. In order to improve the bonding performance between basalt fiber products and resins, they need to be impregnated in an organic solvent with good bonding with the resin so that the organic solvent is evenly distributed on the fiber surface, and then dehydrated and dried before use.

[0004] Drying efficiency depends on the residual liquid rate of the fiber after dehydration and the temperature of the drying oven. The longer the drying time, the higher the energy consumption. Since the fiber surface is organic, the drying temperature should not exceed 100℃. Therefore, the drying efficiency of the final product depends on the residual liquid rate of the fiber product after dehydration.

[0005] Currently common dehydration methods include natural draining, which is time-consuming and inefficient; extrusion dehydration, which can easily damage the structure of fiber products and leaves a lot of residual moisture, making it impossible to completely remove the liquid between the fibers, thus prolonging the subsequent drying time; and centrifugal dehydration, which is energy-intensive and can easily damage the structure of fiber products. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by providing a device for accelerating the removal of liquid from wet basalt fiber materials, with the aim of accelerating the discharge of liquid from the fiber materials to significantly reduce the time and energy consumption of subsequent drying.

[0020] In the above technical solution, preferably, the porous suction plate is embedded above the flow guide groove;

[0021] The porous suction plate is made of one of the following materials: stainless steel, plastic plate, or aluminum plate.

[0022] The beneficial effects of this utility model are:

[0023] This invention lays wet fiber material flat on top of filter cloth, and uses a vacuum pump to make the liquid enter the guide channel through the holes of the porous suction plate and then flow into the collection tank for collection.

[0024] The porous suction plate and the inverted conical guide channel are detachable, which facilitates cleaning of both and the collection tank after disassembly.

[0025] The porous suction plate and the guide channel work together to apply negative pressure evenly to the fiber material, and specifically suck up the interstitial liquid, which improves the efficiency of traditional centrifugal dehydration by more than 40%.

[0026] After suction, the fiber moisture content is reduced to below 20%, and the subsequent drying energy consumption is reduced by 50%-70%.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0032] See Figures 1-3 A device for accelerating the dehydration of wet basalt fiber material products includes a suction platform 1. The suction platform 1 includes a liquid collection tank 2 and several support rods 11 arranged below the liquid collection tank 2. The support rods 11 provide support and can be used as part of the suction platform 1 or directly fixed below the liquid collection tank 2.

[0033] In this embodiment, a porous suction plate 3 is installed on the suction platform 1. The porous suction plate 3 includes multiple holes 31 for liquid to pass through, such as... Figure 2 The diagram shows a layout of one type of hole position 31.

[0034] To facilitate the installation of the porous suction plate 3, in one embodiment, the suction platform 1 includes an inner edge 12 for supporting the porous suction plate 3. The upper surface of the inner edge 12 is located below the upper surface of the suction platform 1 to form an area for accommodating the porous suction plate 3, thereby realizing the embedded installation of the porous suction plate 3. In one embodiment, after the porous suction plate 3 is installed, its upper edge is flush with the upper edge of the suction platform 1.

[0035] In this embodiment, a filter cloth 4 is installed above the porous suction plate 3. As one option, the mesh count of the filter cloth 4 is greater than or equal to 2000 mesh. The filter cloth 4 covers all the holes 31 on the porous suction plate 3. Of course, the filter cloth 4 can also be spread all over the upper surface of the suction table 1, including the entire porous suction plate 3, which is located below the filter cloth 4.

[0036] The material of the porous suction plate 3 can be one of stainless steel, plastic plate, or aluminum plate.

[0037] In this embodiment, a guide channel 5 is installed inside the liquid collection tank 2. The guide channel 5 can be detachably installed inside the liquid collection tank 2 and can be positioned at the liquid collection tank 2 after installation. The detachability of the guide channel 5 and the porous suction plate 3 facilitates cleaning after disassembly. After disassembly, they can be directly rinsed with clean water. At the same time, the disassembly of both facilitates cleaning of the liquid collection tank 2.

[0038] In one embodiment, the guide channel 5 is inverted conical in shape, and the holes 31 of the porous suction plate 3 are arranged above the liquid inlet (the upper opening of the guide channel) of the guide channel 5. A liquid guide pipe 51 is fixed at the lower part of the guide channel 5, and a gap is left between the lower end of the liquid guide pipe 51 and the bottom surface of the liquid collection tank 2.

[0039] In this embodiment, the liquid collection tank 2 is connected to a vacuum pump connecting pipe 6, a vacuum gauge 61 is installed on the vacuum pump connecting pipe 6, and a vacuum pump 7 is connected to the end of the vacuum pump connecting pipe 6. As one option, the vacuum pump connecting pipe 6 is connected to the upper side of the liquid collection tank 2.

[0040] In this embodiment, a drain hole 21 is provided below the liquid collection tank 2, and a drain pipe 8 is connected to the drain hole 21. A drain valve 81 is installed on the drain pipe 8, and a liquid recovery tank 9 is provided below the drain pipe 8. The lower end of the drain pipe 8 can extend into the liquid recovery tank 9 to prevent liquid from splashing out of the liquid recovery tank 9.

[0041] In practical use, the wet fiber material is laid flat on the filter cloth 4, and the vacuum pump 7 is started while the drain valve 81 is closed. The liquid enters the inverted conical guide channel 5 through the hole 31 of the porous suction plate 3 and then flows into the collection tank 2 for collection.

[0042] After working for a period of time, manually open the drain valve 81 to drain the liquid;

[0043] After use, remove the porous suction plate 3 and the guide channel 5, rinse them with clean water, and clean the collection tank 2 at the same time.
