Description

Technical Field

[0001] The utility model relates to the technical field of furnace eye cleaning, in particular to a furnace eye expanding device for a manganese silicon alloy ore furnace. Background Art

[0002] Silicon manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. It is a ferroalloy with wide application and large output. It contains sufficient silicon. The melting temperature range is 1075℃-1320℃. It is mostly smelted in open fixed ore-fired electric furnaces. In recent years, rotary and closed electric furnaces have been used for production. Silicon manganese alloy is a reducing agent for smelting medium and low carbon ferromanganese and metallic manganese. It is also used as a composite deoxidizer, alloying agent and desulfurizer in steelmaking production. After the furnace eye has been used for a period of time, waste slag is prone to accumulate inside and cause blockage.

[0003] The existing method uses a steel chisel or a steel brush to manually clean the slag in the furnace eye. When cleaning, the steel brush is inserted into the furnace eye from the outside. During the insertion process, the steel brush will contact the slag in the furnace eye. When moving inward, the slag is easily passed into the furnace body, affecting the purity and quality of the alloy during smelting. Therefore, we propose a furnace eye expansion device for manganese silicon alloy ore furnace. Utility Model Content

[0004] The utility model aims to provide a furnace eye expansion device for a manganese silicon alloy ore furnace. By setting a conical cylinder and a guide cylinder connected thereto, the guide cylinder is first inserted into the inner position of the furnace eye, so that the brush rod can drive the steel rope brush to pass through the conical cylinder and the guide cylinder. When the steel rope brush enters the furnace eye, it will not touch the interior and bring in waste slag. After that, the steel rope brush passes through the guide cylinder to the inner side of the furnace eye and unfolds. When it is pulled outward, the waste slag will be brushed out to the outside for cleaning using the steel rope brush, thereby solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manganese silicon alloy ore furnace eye expansion device, comprising a conical cylinder and a brush rod, the bottom of the conical cylinder is connected to a guide cylinder connected to its interior, a connecting rod is connected and fixed to the upper surface of the side of the conical cylinder, and a first handle is transversely welded and fixed to the top end of the connecting rod; a plurality of steel rope brushes are evenly fixed to the outer ring of the bottom of the brush rod, the ends of the steel rope brushes are embedded in the surface of the brush rod, and a second handle is transversely welded and fixed to the top end of the brush rod.

[0006] By adopting the above technical solution, the guide cylinder is first inserted into the inner side of the furnace eye, and then the brush rod drives the steel rope brush to pass through, which will force the steel rope brush to be in a contracted state and enter the inner side of the furnace eye, and then be pulled out to the outside, and the waste slag is brushed out to the outside by the unfolded steel rope brush.

[0007] Optionally, a first rubber sleeve is sleeved on the outer ring of the first handle, and the inner ring of the first rubber sleeve is tightly pressed against the outer surface of the first handle.

[0008] By adopting the above technical solution, a comfortable and non-slip gripping effect can be obtained by gripping the outer ring of the first handle with the first rubber sleeve.

[0009] Optionally, a first side handle is fixed to the side of the connecting rod below the first grip, and the first side handle is fixed to the side of the connecting rod by welding.

[0010] By adopting the above technical solution, the first side handle is used to assist in operating the connecting rod, so that the connecting rod can be conveniently held.

[0011] Optionally, a second rubber sleeve is sleeved on the outer ring of the second handle, and the inner ring of the second rubber sleeve is tightly pressed against the outer surface of the second handle.

[0012] By adopting the above technical solution, a comfortable and non-slip gripping effect can be obtained by gripping the outer ring of the second handle with the second rubber sleeve.

[0013] Optionally, a second side handle is fixed to the side of the brush rod below the second gripping handle, and the second side handle is fixed to the side of the brush rod by welding.

[0014] By adopting the above technical solution, the second side handle is used to assist in operating the brush rod, so that the brush rod can be conveniently held.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The technical solution of the present application is to set a cone cylinder and a guide cylinder connected thereto, and first insert the guide cylinder to the inner side of the furnace eye, so that the brush rod can drive the steel rope brush to pass through the cone cylinder and the guide cylinder. When the steel rope brush enters the furnace eye, it will not touch the inside and bring in waste slag. Then the steel rope brush passes through the guide cylinder to the inside of the furnace eye and unfolds. When it is pulled outward, the waste slag will be brushed out and cleaned by the steel rope brush, so as to avoid waste slag entering the furnace body and affecting the smelting purity of the alloy.

[0017] 2. The technical solution of the present application facilitates auxiliary operation to drive the connecting rod or the brush rod by means of the first side handle and the second side handle fixed on the side of the connecting rod and the side of the brush rod.
