Jet type feeding device for high-performance production of basalt fibers

Abstract

The invention discloses a jet type feeding device for high-performance production of basalt fibers. The jet type feeding device comprises a feeding part, a batching part and a throwing part, the batching part comprises a batching bin, a sliding rod and a sliding block, the top and the bottom of the batching bin are respectively opened, a top opening of the batching bin is communicated with the feeding part, the feeding part feeds raw materials into the batching bin from the top opening, the shape and size of a bottom opening of the batching bin are consistent with those of the sliding block, the sliding block is connected with the sliding rod, the sliding rod drives the sliding block to move up and down and slide to the bottom opening of the batching bin or slide away from the bottom opening of the batching bin to close or open the batching bin, the throwing part comprises a material throwing bin, a material throwing air cylinder and a shielding plate, the material throwing air cylinder pushes the material throwing bin to move towards a smelting furnace, the shielding plate is obliquely arranged at the front end of the material throwing bin, and raw materials in the material throwing bin are pushed by the material throwing air cylinder to be accelerated and thrown into the smelting furnace along the elevation angle formed by the shielding plate under shielding of the shieldingplate. According to the invention, raw materials are uniformly thrown and spread in the smelting furnace, and a material pile is prevented from being formed.

Description

technical field [0001] The invention relates to the field of high-performance and stabilized basalt fiber production equipment, in particular to a spray feeding device used for the stabilized production of basalt fiber. Background technique [0002] Basalt fiber: continuous fiber drawn from natural basalt. It is a continuous fiber drawn at high speed by a platinum-rhodium alloy drawing bushing after melting basalt rock at 1450°C to 1500°C. The color of pure natural basalt fiber is generally brown with metallic luster. Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material, which 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 various excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. In addition, the production process of basal...

Problems solved by technology

In the prior art, most feeding machines can realize feeding to the kiln according to the drop of the liquid level, but they cannot do quantitative feeding according to the actual needs. Sometimes they add more, sometimes they add less. Even if the quantitative feeding is done, the accuracy is not enough. The actual feeding The amount is much different from the theoretical calculation value, which is not conducive to the large-scale industrial production of basalt continuous fiber
