Description

Technical Field

[0001] The utility model relates to the technical field of basalt fiber feeding equipment, and more specifically, to a special feeding device for basalt fiber. Background Art

[0002] Basalt fiber is a glass fiber drawn from natural basalt. It is a continuous fiber obtained by high-speed drawing of basalt materials through a platinum-rhodium alloy wire-drawing nozzle after melting at 1450°C to 1500°C, and its strength is equivalent to that of high-strength S glass fiber. Basalt fiber is a new type of inorganic environmental protection green high-performance fiber material, which is made by melting basalt materials composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide, and titanium dioxide, and then quickly drawing through a nozzle. 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 production and processing of basalt fiber composites, when adding materials to the basalt fiber composites, the fiber materials are usually added to the reaction cylinder from the feed port at one time, resulting in a large amount of accumulation of materials in the cylinder, poor dispersion, and relatively large fiber materials themselves. After the fiber materials accumulate in the cylinder, it causes subsequent mixing pressure and reduces the mixing efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a special feeding device for basalt fiber, which can achieve the uniformity and stability of the feeding method and improve the mixing efficiency of raw materials in the subsequent reaction cylinder.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Embodiment 1

[0021] A special feeding device for basalt fibers, comprising a reaction cylinder 1, a feed inlet 2 is arranged on the reaction cylinder 1, a rotating shaft 13 is arranged in the reaction cylinder 1, a cloth hopper 10 is arranged on the rotating shaft 13, the upper end surface of the cloth hopper 10 is open, and a plurality of discharge holes 11 and / or discharge grooves 12 are arranged on the side surface of the cloth hopper 10, and the discharge end of the feed inlet 2 is located above the cloth hopper 10.

[0022] Working principle: When the present utility model is in use, basalt fibers are fed in through the feed inlet 2, and the basalt fiber materials immediately all fall into the cloth hopper 10. At the same time, the rotating shaft 13 rotates driven by an external driving motor 5, driving the cloth hopper 10 to rotate, so that the basalt fibers falling into the cloth hopper 10 rotate in the cloth hopper 10 and are discharged through the discharge holes 11 and / or discharge grooves 12 on the side wall of the cloth hopper 10, so that the basalt fiber materials are sprayed out of the cloth hopper 10 in a centrifugal motion manner and in multiple angular directions and fall into the reaction cylinder 1, realizing the uniformity of the feeding of basalt fiber materials, improving the mixing efficiency after feeding, avoiding the phenomenon of accumulation of basalt fiber materials falling into the reaction cylinder 1, realizing the uniformity and stability of the feeding method, and ensuring the mixing efficiency of the raw materials in the subsequent reaction cylinder 1.

[0023] In this embodiment, the inner diameter of the upper end of the cloth hopper 10 is greater than or equal to the inner diameter of the lower end. For example, the longitudinal section of the cloth hopper 10 is in the shape of a cylinder, an inverted frustum or an inverted cone, and preferably an inverted frustum shape. In this way, the cloth hopper 10 can receive the materials fed from the upper feed inlet 2 with a larger open area and disperse the materials into the reaction cylinder 1 at a larger centrifugal speed.

[0024] In this embodiment, the cloth hopper 10 is arranged close to the feed inlet 2 to receive the fiber materials quickly and disperse the fiber materials into the reaction cylinder 1 quickly.

[0025] In this embodiment, a feed hopper 4 is further arranged on the feed inlet 2, and two crushing rollers 3 are arranged in the feed hopper 4; thus, the entering basalt fiber materials are preliminarily crushed by the relative movement between the two crushing rollers 3 so that the fiber materials can be fed more smoothly and blockage can be avoided. At the same time, it is also beneficial for the fiber materials to be more quickly and smoothly dispersed out of the cloth hopper 10 after entering the cloth hopper 10.

[0026] In this embodiment, a plurality of air supply ports 9 are provided on the inner side wall of the reaction cylinder 1. One end of the air supply port 9 extends into the reaction cylinder 1, and the other end of the air supply port 9 is communicated with an air supply source through an air supply pipe 8. An air outlet 6 is further provided at the top of the reaction cylinder 1. By blowing air on the inner side surface of the reaction cylinder 1, the fiber material can be sprayed down more uniformly from the cloth hopper 10, so as to be mixed more uniformly with the raw materials in the reaction cylinder 1. At the same time, the gas is discharged through the air outlet 6 at the top of the reaction cylinder 1.

[0027] Since fiber dust will be generated when the basalt material is crushed and dispersed by the cloth hopper 10, in this embodiment, a dust collection bag 7 is connected to the outer end of the air outlet 6, so that the dust can be collected and processed in time, improving the cleanliness of the working environment.

[0028] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
