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

Embodiment
[0032]First, the control system issues an instruction to close the flapper valve at the discharge port of the feeding pipe 2, and then open the ball valve at the feeding port to feed the material into the feeding pipe 2, and monitor the basalt rock in the feeding pipe 2 in real time through the weighing sensor 5 When the quality of the added basalt rock reaches the set value, the load cell 5 sends a signal to the control system, and the control system sends an instruction to close the ball valve. Before the feeding pipe 2 feeds the kiln, a certain amount of basalt rock is always stored in the feeding pipe 2. During the storage process, the basalt rock is gradually preheated to 600°C to 900°C by the high temperature environment in the kiln. The liquid level detection device regularly detects the liquid level height of the melt in the kiln. When the liquid level drops, it converts the drop value and speed into digital signals and sends them to the control system. Calculate the m...

The invention discloses a kiln feeding device for producing basalt continuous fibers. The kiln feeding device for producing the basalt continuous fibers comprises a raw material bin, wherein the raw material bin is arranged on the top of a kiln; the bottom plate of the raw material bin is connected with a plurality of feeding tubes; the discharging tubes are positioned in the kiln; a feeding opening of each feeding tube is provided with an upper check valve; a discharging opening of each feeding tube is provided with a lower check valve; and the upper check valves and the lower check valves are controlled to be opened or closed by a computer control system so that materials can be fed in the kiln via the feeding tubes. The control system is also connected with a liquid level height detecting device and a weighing sensor. By the feeding device, basaltine stones can be preheated, and are quantitatively fed into the kiln, so that the melting rate of the basaltine stones dropping in melting liquid is increased, high-precise quantitative feeding is realized, and large-scale industrial production of the basalt continuous fibers can be realized.
Description
technical field [0001] The invention relates to the technical field of basalt continuous fiber production equipment, in particular to a kiln feeding device for producing basalt continuous fiber. Background technique [0002] Basalt continuous fiber is one of the fibers with excellent comprehensive properties. It has the characteristics of high strength, acid and alkali resistance, good high and low temperature performance, and excellent fire resistance. It can be widely used in military and civilian fields. [0003] Today, the production process of continuous basalt fiber is roughly as follows: natural basalt rock is used as a raw material for the production of continuous basalt fiber, and is put into the kiln by a feeder, and is melted into a liquid by the high temperature environment in the kiln. After the melt is further clarified and homogenized, It is transported to several operation units through the material channel. A platinum-rhodium alloy porous drain plate is inst...
