Description
Technical Field
The utility model relates to a subside electric stove and maintain technical field, specifically a simple and easy nozzle of coking in the clearance subsides electric stove furnace body.
Background
In modern copper pyrometallurgy, the electric settling furnace is mainly used for the settling separation of matte and slag, and can also be used for reducing the copper content in the slag. For example, in the Ausmelt smelting furnace-settling electric furnace system, the mixed melt of the Ausmelt furnace is settled and separated into slag and copper by the settling electric furnace, and then the matte and the slag are respectively fed into the next process. For normal production, the temperature of a molten pool in the electric furnace is required to be strictly controlled, and the over-high temperature of the molten pool can aggravate the abrasion of refractory materials and greatly influence the service life of the electric furnace; if the content is too low, caking or aggregation can be generated in the furnace, which affects the separation of slag and copper and obviously increases the content of slag and copper. The electric furnace electrode is a carrier for converting electric energy into heat energy, and the temperature around the electrode is obviously higher than that far away from the electrode. Therefore, the electric furnace far away from the electrode, particularly the four corners of the electric furnace, is coked due to inevitable agglomeration of the electric furnace slag at a low temperature, and in addition, the high-temperature fan takes away sulfur smoke in a hearth of the electric furnace, and simultaneously takes away heat contained in the sulfur smoke, the temperature of the hearth is about 700 ℃ for a long time, so that the coking in the electric furnace is rapidly increased. The effective area of the electric furnace molten pool is reduced by coking in the electric furnace, so that the sedimentation time of the mixed melt of the Australian furnace is reduced, and the copper content in the slag is increased. The cleaning of coking in the electric furnace is imperative.
The traditional method is to increase the electrode power periodically, namely to increase the temperature of a molten pool for a short time, and simultaneously to add fuels such as pulverized coal or diesel oil to a coking position by using an electric furnace reduction burner at an electric furnace observation hole to increase the temperature so as to reduce the coking. However, the reduction burner can only reduce coking near the observation hole and cannot clean other positions, so that the coking of the electric furnace, particularly corners of the electric furnace far away from the electrode, is thicker and thicker.
Disclosure of Invention
The utility model aims at solving the problem that the corner coking of the electrode is more and more thick when the existing electric furnace is used for production, and providing a simple burner for cleaning and settling the coking in the electric furnace body.
The utility model has the following concrete scheme: the utility model provides a simple and easy nozzle of coking in clearance settlement electric stove furnace body, includes nozzle core, shell, nozzle point, nozzle core includes the base, is equipped with the oil circuit pillar on the base, and oil circuit pillar center is equipped with the oil passageway, and oil passageway top is equipped with the oil-out, and oil passageway bottom is located oil circuit pillar lateral wall and is equipped with the oil inlet, the shell cover is in on the base, have the clearance between shell and the oil circuit pillar outer wall and form the air cavity, the shell lateral wall is equipped with the air inlet, nozzle point includes the sleeve of being connected with the shell, and the sleeve top is equipped with the toper cover, toper cover inner chamber with the air cavity intercommunication, toper cover top center is equipped with the venthole, and oil circuit pillar top is located the venthole, has.
Sleeve and shell threaded connection.
The equipartition has a plurality of supporting shoe on the outer wall of oil circuit pillar top, shell top inner wall and supporting shoe contact.
Air inlet and oil inlet are located same direction, and oil pipe is connected to the oil inlet, and oil pipe wears out from the air inlet.
The working principle of the utility model is as follows: firstly, observing coking in a furnace, estimating the decoking time of the device according to the coking area in the furnace, then respectively connecting an oil inlet and an air inlet with a fuel source and an air source through a metal hose and a pipeline, then welding a supporting rod on the device, putting a burner into the furnace, manually adjusting the angle and the height of the supporting rod to move the burner to a position to be cleaned and fix the burner, finally opening a compressed air valve, simultaneously opening an oil pipe valve, enabling oil to flow to the tip of the burner from an oil channel and spray out, combusting the mixture of air and oil under the action of high temperature of a hearth to form jet flame, heating and decoking the coking, confirming whether the coking is finished or not through an observation port of the electric furnace after the decoking time is up, then closing the oil pipe and the compressed air pipeline valve, and taking.
Compared with the prior art, the utility model has the following advantages: simple structure, weight is lighter, and the manual work is according to the nimble removal in coking position, can be with the coking clean up in each corner in the stove, has improved decoking efficiency.
