Description

Technical Field

[0001] The utility model relates to a furnace wall spray gun structure which can be disassembled and replaced, belonging to the technical field of electric furnace powder injection. Background Art

[0002] The spray gun on the furnace wall of the electric furnace is in the form of stainless steel pipe welding, made by on-site welding of stainless steel pipes by oneself, installed beside the burner on the furnace wall of the electric furnace, and the rubber hose is used for connection of the spray gun. Since the carbon powder is continuously used for each furnace of steel, the service life of the spray gun made of stainless steel is only 24 hours and then it must be replaced, so the service life is too low; frequent replacement of the spray gun is required, which takes up the production power-on time. In addition, the operating environment temperature is too high, and the longer the spray gun replacement time is, the greater the risk is. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a furnace wall spray gun structure which can be disassembled and replaced aiming at the above-mentioned prior art, so as to improve the service life, facilitate replacement, reduce the spray gun replacement time and reduce the labor intensity of workers.

[0004] The technical solution adopted by the utility model to solve the above problems is as follows: a furnace wall spray gun structure which can be disassembled and replaced, including a return tank, the return tank is provided with interfaces: an inlet joint and an outlet joint, the inlet joint is connected with one end of a connecting pipe, the other end of the connecting pipe is detachably connected with an input rubber hose, the outlet joint is detachably connected with one end of a spray pipe, and the other end of the spray pipe is inserted into the electric furnace.

[0005] The other end of the connecting pipe and the input rubber hose are connected through a quick connector.

[0006] The quick connector is a lever-type quick connector.

[0007] Connecting flanges are respectively arranged at the outlet joint and the inlet end of the spray pipe, and the two connecting flanges are fixedly connected through connecting bolts.

[0008] The spray pipe is a ceramic made part, and the input rubber hose is an input ceramic rubber hose.

[0009] Compared with the prior art, the advantages of the utility model are as follows: for a furnace wall spray gun structure which can be disassembled and replaced, the scouring force of the carbon powder is reduced after being turned by the return tank, so the service life is improved. The spray pipe and the outlet joint are connected through fixing bolts, and the connecting pipe and the input rubber hose are connected through a quick connection interface. If damage occurs, local replacement can be carried out, and the replacement is convenient, the replacement time is reduced, and the labor intensity of workers is reduced. Description of the Drawings

[0010] Figure 1 It is a schematic diagram of a furnace wall spray gun structure which can be disassembled and replaced according to an embodiment of the utility model;

[0011] In the figure, there are injection pipe 1, swivel tank 2, connecting pipe 3, quick connector 4, input ceramic hose 5, joint 6, and connecting flange 7. Specific embodiments

[0012] The following further describes the present utility model in detail with reference to the embodiments in the accompanying drawings.

[0013] As Figure 1 shown, a separable replaceable furnace wall spray gun structure in this embodiment includes a swivel tank 2. There are two joints 6 on the outer periphery of the swivel tank 2: an inlet joint and an outlet joint. The inlet joint is connected to one end of the connecting pipe 3, and the other end of the connecting pipe 3 is connected to the input ceramic hose 5 through the quick connector 4. A spray pipe 1 made of ceramic is provided on the outlet joint. Connecting flanges 7 are respectively arranged at the outlet joint and the inlet end of the spray pipe 1. A sealing ring is arranged between the two connecting flanges 7 and is fixedly connected through connecting bolts. The other end of the spray pipe 1 is inserted into the electric furnace.

[0014] The quick connector is a lever-type quick connector.

[0015] Both the spray pipe and the input hose are made of ceramic material. The ceramic material is wear-resistant, which improves the service life of the spray pipe and the input hose.

[0016] Insert the spray pipe into the furnace. The carbon powder flows into the swivel tank through the input ceramic hose and the connecting pipe for turning, reducing the erosion, and then is sprayed into the furnace through the outlet joint and the spray pipe. The erosion force of the carbon powder is reduced after turning by the swivel tank, which improves the service life. The spray pipe and the outlet joint are connected by fixing bolts, and the connecting pipe and the input hose are connected by quick connectors. If there is damage, it can be replaced locally, and the replacement is convenient, reducing the replacement time and the labor intensity of workers.

[0017] In addition to the above embodiments, the present utility model also includes other implementation manners. All technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present utility model.
