Automatic furnace eye opening and blocking machine device for closed submerged arc furnace

Abstract

The invention discloses an automatic furnace eye opening and blocking machine device for a closed submerged arc furnace. The automatic furnace eye opening and blocking machine device comprises a bearing table, a clay gun barrel, a drilling barrel, a dismounting and mounting mechanism and an adjusting mechanism, wherein the clay gun barrel and the drilling barrel are arranged above the bearing table, the dismounting and mounting mechanism is arranged on the clay gun barrel, and the adjusting mechanism is arranged on the drilling barrel. The dismounting and mounting mechanism comprises a clay gun head, a positioning rod, a supporting bearing, a movable disc, a magnetic attraction rod, a stop block, an electric telescopic rod, an electromagnet and a control switch, the outlet end of the clay gun barrel is sleeved with the clay gun head, the positioning rod is fixedly arranged on the bottom face in the clay gun head, and the supporting bearing is fixedly arranged on the inner wall, close to the outlet end, of the clay gun barrel. The adjusting mechanism comprises a sliding block, a driving motor, a lead screw, a micro motor, a bearing disc, a reset spring, a guide rod and a rubber cylinder, a sliding groove is formed in the inner wall, close to the top end, of the drilling barrel, and the sliding block is movably arranged on the sliding groove. The clay gun head can be easily and effortlessly dismounted and mounted, and the clay gun head cannot be damaged; a drill bit and a cover cap can be flexibly and stably adjusted; and the stability of all fixed connection parts of the equipment is also guaranteed.

Description

technical field [0001] The invention relates to the technical field of an eye opening machine, in particular to an automatic eye opening machine device for a closed submerged arc furnace. Background technique [0002] Submerged arc furnace is also called electric arc furnace or resistance electric furnace. It is mainly used for reducing smelting ores, carbonaceous reducing agents and solvents and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon-manganese alloy and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. In the process of preparing various alloys in the closed submerged arc furnace, if you want to obtain the molten and high-temperature liquid alloy in the closed submerged arc furnace, you need to open the furnace eye of the submerged arc furnace (both open the eye), and the high-temperature liquid in the submerge...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to provide an automatic device for unblocking the hole of a closed submerged arc furnace, which can effectively solve the problem that most of the mud guns of the hole plugging machine in the prior art are integral or are directly connected with the mud gun head by clamps and are disassembled. The resistance during installation is large and not smooth. Excessive force will easily cause damage to the mud gun head. It is inconvenient to clear the mud after the hole is blocked, and the adjustment and expansion of the drill bit is not flexible and stable enough. When pounding the furnace hole, the drill bit will be stressed for a long time. The impact will also be deformed and blocked in the drill barrel
