DETAILED DESCRIPTION

[0016] In order to facilitate the understanding of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0017] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "front", "rear", "left", "right", "up", "down", and "inside" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of description. They do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0018] like Figure 1As shown, the main body of the desulfurization spray gun vertical baking electric kiln disclosed in the utility model is a kiln body 100, and a baking channel 200 is arranged inside the kiln body 100. Because the baking object of the utility model is the desulfurization spray gun 400, the main body shape of the desulfurization spray gun 400 is a long cylinder. In order to improve the baking effect of the desulfurization spray gun 400, the utility model arranges the baking channel 200 as a vertical baking channel arranged vertically along the height direction of the kiln body 100. The shape of the baking channel 200 also adopts a cylindrical channel adapted to the shape of the desulfurization spray gun 400. The length of the baking channel 200 is set according to the overall length of the desulfurization spray gun 400, and sufficient heating space needs to be reserved at the bottom of the baking channel 200; during baking, the desulfurization spray gun 400 can be vertically inserted into the baking channel 200 for baking, so that when the desulfurization spray gun 400 is baked, the desulfurization spray gun 400 is heated more evenly, which can effectively improve the baking quality of the desulfurization spray gun 400.

[0019] Specifically, Figure 1 As shown, the inner wall of the baking channel 200 includes an insulation layer 210 and a refractory layer 220 arranged in sequence from the outside to the inside, and an electric heating wire 230 is arranged on the surface of the refractory layer 220. The insulation layer 210 is built by insulation bricks, and the refractory layer 220 is built by refractory bricks. The electric heating wire 230 is powered on to generate heat to provide heat for baking.

[0020] Furthermore, in order to improve the heating and baking effect of the electric heating wire 230 on the desulfurization spray gun 400, the arrangement of the electric heating wire 230 is improved so that the electric heating wire 230 is arranged in a spiral shape on the surface of the refractory layer 220 along the height direction of the baking channel 200. Then, when the desulfurization spray gun 400 is inserted into the baking channel 200, the electric heating wire 230 can form a spiral surrounding structure on the outside of the desulfurization spray gun 400, and the heat generated by the electric heating wire 230 can be evenly distributed on the peripheral surface of the desulfurization spray gun 400, and there will be no part where the heat cannot be transferred or the heat transfer effect is poor.

[0021] Specifically, the utility model adopts a hanging method to realize the fixation of the desulfurization spray gun 400 in the baking channel 200, and adopts a desulfurization spray gun hanging plate 300 to realize the hanging of the desulfurization spray gun 400 in the baking channel 200. Figure 2 and Figure 3As shown, the desulfurization spray gun hanging plate 300 is composed of two hanging plate blocks 310. The hanging plate blocks 310 are semicircular block structures. The two hanging plate blocks 310 are put together to form a circular desulfurization spray gun hanging plate 300. The utility model realizes the cooperation with the desulfurization spray gun 400 by setting a limiting groove 311 at the bottom of the hanging plate block 310. Since the end of the desulfurization spray gun 400 is fixedly installed with a flange, the utility model forms a limiting cooperation with the flange of the desulfurization spray gun 400 through the limiting groove 311. The edge of the flange of the desulfurization spray gun 400 can be embedded in the limiting groove 311, and the axial and radial limiting cooperation are formed at the same time; the two hanging plate blocks 310 are moved toward each other from both sides of the flange, so that the side edges of the flange are respectively embedded in the limiting grooves 311 of the two hanging plate blocks 310, and the two hanging plate blocks 310 are connected to form the desulfurization spray gun hanging plate 300, and the flange of the desulfurization spray gun 400 is also embedded in the annular limiting groove formed by the two limiting grooves 311.

[0022] In order to provide a stable fixation effect, such as Figure 2 As shown, the utility model provides a plurality of connecting through holes 312 axially penetrating the hanging plate block 310 on the hanging plate block 310 of the desulfurization spray gun hanging plate 300, and the connecting through holes 312 correspond to the connecting holes of the flange plate on the desulfurization spray gun 400, and the flange plate of the desulfurization spray gun 400 is fixedly connected to the desulfurization spray gun hanging plate 300 by bolts.

[0023] Further, such as Figure 1 As shown, the utility model also sets a gasket 240 in a ring shape around the top of the baking channel 200, and the inner diameter of the gasket 240 is larger than the inner diameter of the baking channel 200, and the outer diameter of the gasket 240 is smaller than the diameter of the desulfurization spray gun hanging plate 300. The desulfurization spray gun hanging plate 300 connected with the desulfurization spray gun 400 can be abutted against the gasket 240, and the desulfurization spray gun hanging plate 300 is supported by the gasket 240, and sufficient operating space can be reserved between the desulfurization spray gun hanging plate 300 and the top of the baking channel 200, which is convenient for placing the desulfurization spray gun hanging plate 300 and also convenient for taking the desulfurization spray gun hanging plate 300 out of the kiln body 100.

[0024] Specifically, Figure 1 As shown, the kiln body 100 used in the present invention further includes a steel wall tube 110 arranged outside the insulation layer 210, the bottom of the steel wall tube 110 is sealed, and the top of the steel wall tube 110 is provided with an opening and forms a sealing match with the sealing cover 130. Before baking, the sealing cover 130 is opened to insert the desulfurization lance 400 into the baking channel 200, and the sealing cover 130 is closed during the baking process to prevent heat from overflowing, and the sealing cover 130 is opened after the baking is completed to take out the desulfurization lance 400.

[0025] In order to further improve the baking efficiency of the desulfurization spray gun 400, the number of baking channels 200 in the kiln body 100 can be increased, and multiple baking channels 200 can be used to achieve batch baking of the desulfurization spray gun 400. The multiple baking channels 200 are arranged in parallel in the kiln body 100, and adjacent baking channels 200 are separated by a steel partition layer 120.
