[0015] The technical effects and advantages of the present invention.

[0016] This invention uses an electric cylinder to push the sleeve and move the material cylinder upward, causing the basalt fiber material inside the cylinder to be dispersed and discharged from the center to the edge. Multiple heaters can not only preheat the inside of the kiln, but also heat and melt the narrow gap below the cover sleeve. The flow heating in the narrow gap makes the basalt fiber particles accumulate and the heating more uniform, which accelerates the heating and melting speed and improves the uniformity and efficiency of heating and melting.

[0017] This invention uses an upward movement of the barrel to drive the connecting block and support ring components, causing the pressure block to be squeezed upward along the spiral groove of the rotating shaft, which in turn drives the rotating shaft to rotate. This causes the displacement bar to rotate and disperse the lower row of basalt fiber material around the periphery, optimizing the distribution of the fiber material, avoiding local accumulation, and making the heating more uniform. This helps to improve the quality and effect of basalt fiber electrofusion treatment.

[0018] 3. In this invention, the kiln body is supported by support bars and connecting rods to form a cone. The cone is supported by connecting columns and pressure bars to form a pressure ring and an outer expansion bar. The fiber material in the material cylinder is pressed down along the outer expansion bar, pressure ring and cone, which can ensure that the fiber material is dispersed and flows to the periphery, making the heating more complete and uniform, reducing heating dead zones and improving the comprehensiveness and effectiveness of electrofusion treatment.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0028] like Figure 1 - Figure 6 The diagram illustrates a rapid and uniform heating basalt fiber electrofusion furnace, comprising a furnace body 1. A material cylinder 2 is slidably connected to the inner wall of the furnace body 1. A storage and distribution discharge component is installed on the outer wall of the material cylinder 2, comprising: a cover sleeve 3 fixed to the outer wall of the material cylinder 2, with a limiting ring 4 fixedly connected to the outer wall of the cover sleeve 3; a sleeve 5 fixedly connected to the outer wall of the material cylinder 2 and located above the furnace body 1, with an electric cylinder 6 installed on the lower surface of the sleeve 5, the outer wall of the electric cylinder 6 fixedly connected to the furnace body 1, and the electric cylinder 6 used to push the sleeve 5 upward; and a threaded cap 7 threadedly connected to the outer wall of the material cylinder 2 and located above the sleeve 5, with a guide rod 8 fixedly connected to the inner wall of the sleeve 5, the bottom end of the guide rod 8 fixedly connected to the cover sleeve 3. The outer diameter of the cover sleeve 3 is larger than the outer diameter of the limiting ring 4, and the thickness of the limiting ring 4 is greater than the thickness of the cover sleeve 3. The guide rod 8 is slidably connected to the kiln body 1, and the top surface of the guide rod 8 is parallel to the top surface of the sleeve 5.

[0029] In this embodiment, as Figure 1 - Figure 2 As shown, a manual valve 24 is threadedly connected to the bottom end of the kiln body 1. A support frame 25 is fixed to the lower surface of the kiln body 1 near its edge. A gap is provided between the limiting ring 4 and the inner wall of the kiln body 1. A slide 26 is fixed to the bottom end of the inner wall of the support frame 25. A controller 27 is installed on one side of the support frame 25. Multiple heaters 28 are provided outside the limiting ring 4, and all of the heaters 28 are connected to the kiln body 1. The support frame 25 supports the kiln body 1, increasing its stability. Closing the manual valve 24 allows the top of the kiln body 1 to be sealed. At the same time, the controller 27 can activate the electric cylinder 6, which pushes the sleeve 5 upward, while the multiple heaters 28 heat the interior of the kiln body 1.

[0030] In this embodiment, when in use, the threaded cap 7 is reversed, separating the threads between the threaded cap 7 and the material cylinder 2. Basalt fiber material is then poured into the material cylinder 2 until it is full. The threaded cap 7 is then rotated forward, closing the threads between the threaded cap 7 and the material cylinder 2. The electric cylinder 6, supported by the kiln body 1, pushes the sleeve 5 upwards. The sleeve 5 moves the material cylinder 2 upwards, which in turn moves the threaded cap 7 upwards. The material cylinder 2 moves upwards along the inner wall of the kiln body 1. Simultaneously, the material cylinder 2... The cover sleeve 3 moves downward, and the heating treatment is achieved through multiple heaters 28 inside the kiln body 1. In this way, the material cylinder 2 moves upward continuously. At the same time, the cover sleeve 3 drives the guide rod 8 to move upward along the interior of the kiln body 1. In this way, the basalt fiber material inside the material cylinder 2 is continuously discharged downward, and it is distributed downward from the middle to the edge of the material cylinder 2. At the same time, the multiple heaters 28 can preheat the interior of the kiln body 1, and the multiple heaters 28 heat and melt the narrow gap below the cover sleeve 3, continuously dispersing and heating the basalt fiber material. Example

[0031] In this embodiment, as Figure 4 - Figure 5 As shown, multiple connecting blocks 9 are provided above the cover sleeve 3, and all connecting blocks 9 are fixedly connected to the material cylinder 2; a support ring 10 is fixedly connected to one end of the connecting blocks 9, and a sliding column 11 is fixedly connected to the inner wall of the support ring 10, and a pressure block 12 is fixed to one end of the support ring 10; a rotating shaft 13 is located on one side of the pressure block 12, and a spiral groove 14 is opened on the outer wall of the rotating shaft 13, the pressure block 12 is slidably connected along the rotating shaft 13 to which the spiral groove 14 belongs, the rotating shaft 13 is slidably connected to the cover sleeve 3, and the top end of the rotating shaft 13 is rotatably connected to the kiln body 1; a rotating ring 15 is fixedly connected to the outer surface of the rotating shaft 13 and near its bottom end, and a displacement strip 16 is fixed to one side of the outer wall of the rotating ring 15, and both the spiral groove 14 and the rotating ring 15 are rotatably connected to the kiln body 1. The cross-sectional shape of the rotating shaft 13 is semi-circular, and the sliding column 11 and the pressure block 12 are arranged perpendicularly. An arc-shaped gap is formed between the support ring 10 and the rotating shaft 13, and the rotating ring 15 and the rotating shaft 13 are coaxially arranged.

[0032] In this embodiment, when the material cylinder 2 moves upward, the material cylinder 2 drives multiple connecting blocks 9 to move upward, the connecting blocks 9 drive the support ring 10 to move upward, the support ring 10 causes the sliding column 11 to move upward, the sliding column 11 drives the pressure block 12 to move upward, the pressure block 12 squeezes upward along the spiral groove 14 on the inner wall of the rotating shaft 13, so that the pressure block 12 meshes with the rotating shaft 13, thereby the pressure block 12 continuously squeezes the rotating shaft 13, causing the rotating shaft 13 to rotate inside the cover sleeve 3. At the same time, the cover sleeve 3 slides upward along the outer wall of the rotating shaft 13, and the rotating shaft 13 drives the displacement bar 16 to rotate, so that the displacement bar 16 realizes the peripheral rotation and dispersion operation of the basalt fiber material discharged from the material cylinder 2. Example

[0033] In this embodiment, as Figure 6 As shown, the inside of the material cylinder 2 is provided with a pressure strip 17; a pressure ring 18, fixed to the bottom end of the pressure strip 17, and an outwardly expanding strip 19 fixed to the lower surface of the pressure ring 18. The outer diameter of the outwardly expanding strip 19 is larger than the outer diameter of the pressure ring 18. A connecting column 20 is fixedly connected to one side of the pressure strip 17; a cone 21, fixed to the bottom end of the connecting column 20, and a connecting rod 22 fixed to the center of the bottom end of the cone 21. A support strip 23 is fixed between the connecting rod 22 and the kiln body 1. The outer wall of the outwardly expanding strip 19 is rounded, and the outer diameter of the top end of the connecting column 20 is smaller than the outer diameter of its bottom end.

[0034] In this embodiment, during use, the kiln body 1 supports the support bar 23, the support bar 23 supports the connecting rod 22, the connecting rod 22 provides support for the cone 21, and the cone 21 supports the connecting column 20, the connecting column 20 provides support for the pressure bar 17, the pressure bar 17 supports the pressure ring 18, and the pressure ring 18 supports the outward expansion bar 19. In this way, the basalt fiber material inside the material cylinder 2 is pressed down along the outward expansion bar 19, the pressure ring 18, and the cone 21 to ensure that the basalt fiber material is dispersed and flows to the periphery.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
