Technical Field

The present invention relates generally to tapping methods and, more particularly, to a method for tapping and broaching an industrial silicon furnace.

Background

At present, the opening and broaching of the industrial silicon furnace are both carried out manually. Because the industrial silicon furnace is huge and the temperature of furnace slurry is very high, the industrial silicon furnace is very dangerous when being operated manually, and particularly when the furnace is opened and broached, the pressure in the furnace is high, and high-temperature liquid can be sprayed out sometimes to cause personal injury. In addition, because the opening and the broaching of the industrial silicon furnace have large eye positions, the required operating tools are thick, and a long distance is required for safety, so the length and the thickness of the operating tools are large, the manual operation is very laborious, the manpower and the material resources are greatly wasted, and the working efficiency is low. Moreover, as the viscosity of the furnace slurry is higher, when the pressure is reduced, the discharging speed is slow, and the working efficiency is seriously influenced. Finally, because the industrial silicon furnace needs to follow up during operation during rotation, the existing operation follow-up is difficult to realize, the eye alignment is not accurate enough, the error is high, the cost is objectively improved, and the working efficiency is reduced.

Therefore, how to automatically open and draw eyes and improve the controllability of operation is a technical problem which needs to be solved urgently at present.

Nothing in this specification should be construed as requiring a specific three dimensional orientation of structures in order to fall within the scope of the invention.

As shown in fig. 1, the tapping method of industrial silicon of the embodiment is used for opening and broaching an industrial silicon furnace 1, and comprises a guide rail 2, a follow-up device 3, a driving trolley 4, a camera 5, a remote control system 6 and a gripping tool 8. Wherein, the guide rail 2 is arranged close to the industrial silicon furnace 1, and the outer part of the guide rail is wound around the whole or part of the furnace body of the industrial silicon furnace 1. The follow-up device 3 is movably arranged on the guide rail 2. The driving trolley 4 is arranged on the follow-up device 3. The camera 5 is used for monitoring the states of the industrial silicon furnace 1, the follow-up device 3 and the driving trolley 4. The remote control system 6 is separately arranged far away from the operation site of the industrial silicon furnace 1, and controls the follow-up device 3 and the driving trolley 4 according to the information sent by the camera 5.

In the embodiment, the follow-up device 3 moves synchronously with the industrial silicon furnace 1 under the control of the remote control system 6, so that the relative position of the driving trolley 4 and the industrial silicon furnace 1 is always kept correct in the operation process.

In addition, the gripper tool 8 can be switched between three operating states. Wherein, the first state is used for grabbing the tool 20 for opening the furnace eye, the rotary rapping is used for drilling the furnace eye, the second state is used for grabbing the burner 30 for melting the furnace eye, the third state is used for grabbing the tool 30 for drawing the furnace eye, and the furnace liquid is drained. The grabbing tool 8 is concentrically arranged when grabbing the open-eye tool 20, the burnthrough device 30 and the pull-eye tool 30, so that the central position of the grabbing tool is unchanged, and the furnace eye is conveniently aligned.

In this embodiment, as shown in fig. 2, the open-hole tool 10 is composed of a tool head 13, a support rod 11 and a drill rod 12. The opening tool 10 is connected with a rock drilling machine 812 (shown in figures 5-7) through a threaded vibrating rod, the rock drilling machine 812 has rotating and vibrating functions, and the rock drilling machine 812 drives the drill rod 12 to rotate at a high speed and simultaneously vibrate and feed forwards by assisting in driving the horizontal motion of the trolley 4, so that a furnace eye is opened, and molten silicon flows out.

FIG. 3 is a schematic view of a burner configuration in an industrial silicon tapping method of the present invention shown in an exemplary embodiment.

In this embodiment, as shown in fig. 3, the penetrator 20 is a tool for eye burning, and is composed of a frustum 21, a clamping boss 22, a bracket 23, a copper bar 25 and a carbon rod 24, wherein the frustum 21 is connected with the bracket 23, the copper bar 25 is arranged on the bracket 23 and is connected with and powered on the tail of the bracket 23, and the carbon rod 24 is installed on the tail of the bracket 23. When the furnace is in work, the copper bar 25 is connected with a power supply, the carbon rod 24 is electrified through the conduction of the bracket 23, and the high temperature generated by the electrification of the carbon rod 24 burns through the furnace eye to enable molten silicon to flow out. Since the weight is heavy and the carbon rod 24 is easy to break, the burnthrough device 20 needs to be kept stable in the whole hole burning process, and therefore the second gripper 82 (shown in fig. 5-7) is used for gripping the frustum 21 and clamping the clamping boss 22 to achieve stable clamping.

In this embodiment, as shown in fig. 4, the broaching tool 30 is composed of a frustum 31, a clamping boss 32, a support rod 33, a clamping head 34 and a drill rod 35, wherein the frustum 31, the support rod 33 and the clamping head 34 are coaxially arranged and can be welded or installed. The drill rod 35 is fitted into the collet 34. The industrial silicon is viscous and may not flow smoothly after opening, and the tool 30 for pulling the hole needs to be grabbed to move horizontally, so that the tool 30 for pulling the hole reciprocates in the furnace eye, and the silicon in a molten state flows out quickly.

FIG. 5 is a first schematic view of a first exemplary embodiment of a pick-up tool for use in the method of tapping industrial silicon. FIG. 6 is a second schematic view of a pick-up tool configuration in the industrial silicon tapping method of the present invention shown in an exemplary embodiment.
