Embodiment 1

[0018] Such as figure 1 , figure 2 The shown automatic control method for fiber glass melting furnace includes tin bath 4, one end of tin bath 4 is provided with runner 11, and the port of runner 11 is provided with gate 3, and it also includes two video detectors 5 , the two video detectors 5 are located at one end of the tin bath 4 close to the runner 11, and the two video detectors 5 are respectively located on both sides of the tin bath 4, and the two video detectors 5 are connected by an operational amplifier circuit 10 The control circuit 9 is connected with an electric actuator connected with the gate 3 .

[0019] In the present embodiment, the molten glass flows into the tin tank 4 through the flow channel 11 through the gate 3, and forms a molten glass belt 7 at the upper end of the molten tin 6. Two video detectors 5 monitor the two glasses of the molten glass belt 7 respectively. The edge 8 of the liquid flow belt, when the edge 8 of the glass liquid flow deviate...

Embodiment 2

[0021] Such as image 3 As mentioned above, this embodiment is further optimized on the basis of Embodiment 1, specifically: the electric actuator includes a three-phase asynchronous motor 1 and a transmission device 2 connected to each other, and the three-phase asynchronous motor 1 is connected to a control circuit 9 , the transmission device 2 is connected with the gate 3 .

[0022] In this embodiment, the control circuit 9 controls the positive and negative rotation of the three-phase asynchronous motor 1 to drive the transmission device 2 up and down, and the transmission device 2 lifts up and down to drive the gate 3 up and down, so that the automatic lifting of the gate can be realized, and the lifting is continuous, stable and uniform, and can be maximized. Reduce the influence of gate lift on the glass liquid flow belt 7, and improve the quality of glass forming.

[0023] The transmission device 2 of this embodiment can be a screw device, a worm gear device or a lift...

Embodiment 3

[0027] This embodiment is optimized as follows on the basis of any of the above embodiments: the horizontal distance between the video detector 5 and the gate 3 is 15-20 cm.

[0028] In this embodiment, since the molten glass flow enters the tin bath 4 through the gate 3, there is a transition from the flow channel 11 to the molten glass flow zone 7 of required width and thickness, that is, the molten glass flow passes from the flow channel 11 to the There will be an arc-shaped transition section between the formed glass liquid flow belts 7. In order to make the glass liquid flow adjustment more timely and accurate, the designer places the video detector 5 at a distance of 15-20 cm from the gate 3. position, that is, it just corresponds to the middle position of the transition section, so that after the gate 3 is adjusted, the glass liquid flow belt 7 is just at the end of the transition section when the required glass liquid flow is formed, so that all the glass liquid flow be...

Abstract

The invention discloses an automatic control method for a fiber glass melting furnace, which comprises a tin bath (4), a flow channel (11) is arranged at one end of the tin bath (4), and a gate (3) is arranged at the port of the flow channel (11). ), it also includes two video detectors (5), the two video detectors (5) are located at the end of the tin bath (4) close to the runner (11), and the two video detectors (5) are respectively Located on both sides of the tin bath (4), the two video detectors (5) are connected to the control circuit (9) through an operational amplifier circuit (10), and the control circuit (9) is connected to an electric actuator connected to the gate (3) The present invention is not only simple in structure, but also can accurately detect the change of glass liquid flow, so as to timely and accurately control the lift of the gate, while ensuring the stable forming and production of glass, it improves the quality of finished glass and the rate of finished glass, and the efficiency of glass forming and processing improve.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to an automatic control method for a fiber glass melting furnace. Background technique [0002] The melted glass in the tank kiln flows into the tin bath along the flow channel at high temperature. Since the density of the glass is only about 1 / 3 of the tin liquid, it floats on the surface of the tin liquid and forms a uniform glass during its flow. When the glass is cooled to a certain temperature, it is lifted by the transition roller table, leaves the tin bath under the traction force of the conveying roller table, and enters the annealing kiln for annealing. [0003] The runner is the channel connecting the pool kiln and the tin bath. The width of the channel is narrower than the wall of the melting furnace and the front end of the tin bath. The main function of the flow channel is to allow the molten glass to enter the tin bath smoothly. Based on the needs of tin bath productio...
