[0002] Electron beam cold hearth melting furnace can be used to melt titanium sponge briquettes or recycled materials into titanium and titanium alloy ingots. In the vacuum melting process, the electron beam is used as a heat source, and the kinetic energy of high-speed electrons is converted into heat energy to melt the metal. Due to the volatilization of alloy elements, a layer of metal or non-metal volatiles is attached to the silo of the electron beam cold hearth melting furnace. If the volatiles are not cleaned in time, the volatiles will adhere to the surface of the lower furnace material, resulting in the quality of the ingot being affected.

[0003] At present, the cleaning of the silo of the electron beam cold bed melting furnace is all done manually. During the cleaning process, the operator needs to wear protective clothing and dust masks, and use angle grinders and hard brooms to clean the volatiles attached to the inner wall of the silo. Although the staff wear dust masks during cleaning, it is still difficult to completely prevent these harmful substances from causing adverse effects on their health.

[0027] A preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, but the present invention is not limited thereto. The same components are denoted by the same reference numerals. It should be noted that the words "upper", "lower", "front", "rear", "left" and "right" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] Unless otherwise specified, in the following embodiments, the components or parts used that are not specifically specified are all conventional products that can be purchased commercially.

[0029] like Figure 1 As shown, the electron beam cold bed melting furnace silo cleaning device provided by the present invention comprises a motor 1, a belt pulley 2, a wire roller brush 3, an adjustable bearing seat 4, an upper plate 5, a lower plate 6, a support shaft 7 and a control box 8, wherein the belt pulley 2 is fixedly connected to the rotating shaft of the motor 1, the belt pulley 2 is connected to the wire roller brush 3 through a V-belt, and the wire roller brush 3 is connected to the upper plate 5 and the lower plate 6 through the adjustable bearing seat 4. A wire roller brush 3 for cleaning is installed on the adjustable bearing seat 4, and the motor 1 is connected to the control box 8 through a cable. The upper plate 5 and the lower plate 6 are connected by a support shaft 7, and the wire roller brushes 3 are symmetrically arranged on both sides of the support shaft 7. The wire roller brushes 3 on both sides can be automatically adjusted when needed according to the adjustable bearing seat 4 with springs added.

[0030] Figure 2 Schematic diagram of the wire roller brush 3 is shown in FIG. Preferably, the wire roller brush 3 is a carbon steel wire roller brush with a hair length of 80 mm and a high-density hair planting process. The hairs are closely distributed, thereby significantly increasing the cleaning area. In a single cleaning stroke, a large area can be contacted and more impurities can be cleaned, thereby achieving an excellent cleaning effect.

[0031] The adjustable bearing seat 4 is modified to have a spring installed at the threaded rod, so that it has a contraction stroke of about 2 cm when affected by external force. The reason for this is that different parts of the silo will be slightly deformed after being heated for a long time. In order to ensure that the silo wall can be brushed by the wire roller brush, the adjustable bearing seat connected to the wire roller brush must have an automatic adjustment function. This problem can be solved by adding a spring. Figure 3The schematic diagram of the adjustable bearing seat is shown in FIG. Preferably, the adjustable bearing seat 4 is a standard part UCTM206A, the base of which is made of cast iron and the bearing is made of steel; the angle and stroke can be adjusted according to the use requirements, and the adjustment stroke is 0-115mm.

[0032] The upper plate 5 is provided with a docking port 9 for connecting a vacuum cleaner, so that the vacuum cleaner is used to absorb the floating dust swept by the wire roller brush. Preferably, the upper plate 5 and the lower plate 6 are respectively steel plates.

[0033] Figure 4 The schematic diagram of the working state of the electron beam cold bed melting furnace silo cleaning device is shown in FIG. Figure 4 As shown, when in use, first push the electron beam cold bed smelting furnace silo cleaning device of the present invention to the silo port, dock the vacuum cleaner pipeline with the vacuum cleaner docking port 9, turn on the power through the switch button on the control box 8 to start, the motor 1 rotates to drive the belt pulley 2, the belt pulley 2 drives the wire roller brush 3 to rotate, and the cleaner is manually pushed forward to clean the silo. By adjusting the screw locking nut on the adjustable bearing seat 4, and then rotating the screw clockwise forward and counterclockwise backward, rotate the locking nut after rotating to the required distance, the two ends of the wire roller brush are installed on the adjustable bearing seat, and the wire roller brush 3 can be extended and retracted by rotating the direction of the screw on the bearing seat, so as to be used for cleaning the silo walls 10 of different widths. When the silo is locally deformed due to the heating of the electron gun, the adjustable bearing seat 4 with the spring installed will drive the wire brush to automatically shrink or extend to ensure that the silo wall is thoroughly cleaned. The actual picture of the electron beam cold bed smelting furnace silo cleaning device of the present invention is as follows Figure 5 and Figure 6 shown.

[0034] It should be noted that the above-described embodiments are only preferred embodiments of the present invention.
