Description

Technical field:

[0001] The utility model relates to the technical field of vacuum furnace auxiliary equipment, in particular to a dust collecting device for a vacuum furnace charging pot. Background technology:

[0002] The vacuum furnace is used to process lead-bismuth alloy and separate the silver-bismuth metal from it. During the production process, the temperature of the charging pot needs to reach above 450°C for the material to melt. The melted metal liquid is heated by the main furnace to about 1000°C, and then the silver-bismuth metal is separated by vacuum distillation. The temperature of the separated metal liquid is also very high when it reaches the discharge port. The high-temperature metal liquid will produce a small amount of smoke, but the vacuum furnace has no related dust collection system, which has an adverse effect on the on-site working environment and metal balance. Long-term production poses a threat to the occupational health of employees and needs to be improved urgently. Utility model content:

[0003] The utility model aims to provide a dust collecting device for a charging pot of a vacuum furnace, so as to solve the technical problem that the charging pot of a vacuum furnace has no dust collecting system in the prior art.

[0004] The content of the utility model: A dust collecting device for a vacuum furnace charging pot, which comprises a charging pot, a charging trough is installed on the charging pot, a lifting dust collecting hood device is installed above the charging trough, the lifting dust collecting hood device is connected to a dust collecting flue, and a fan is installed in the dust collecting flue.

[0005] Furthermore, the lifting dust hood device includes a dust hood, to which a dust collecting pipe is vertically connected, the dust collecting pipe is slidably connected to the dust collecting flue, a cylinder is vertically installed on the outer wall of the dust collecting flue, and a piston rod of the cylinder is connected to the dust hood.

[0006] Furthermore, an infrared radiation device is installed on the feeding trough, the infrared radiation device is electrically connected to a PLC controller, the PLC controller is electrically connected to a solenoid valve, and the solenoid valve controls the opening and closing of the cylinder.

[0007] Furthermore, the infrared emitting device includes an infrared transmitter and an infrared receiver. Support rods are connected to the outer walls on both sides of the feeding trough. The infrared transmitter and the infrared receiver are installed on the support rods. The infrared receiver is electrically connected to the PLC controller.

[0008] Furthermore, a limiting platform is provided at the top of the dust collecting pipe, the limiting platform is slidably connected to the inner wall of the dust collecting flue, a sealing ring platform is connected to the bottom end of the dust collecting flue, and a sealing gasket is installed on the sealing ring platform.

[0009] Furthermore, the dust collecting flue is connected to the sealing ring platform by bolts.

[0010] The beneficial effects of the utility model are as follows: the utility model arranges a lifting dust collecting hood device above the charging pot of the vacuum furnace. When smoke is generated during the charging pot's material catalysis process, the lifting dust collecting hood device falls to collect dust. When the charging pot is in a charging state, the lifting dust collecting hood device rises without hindering the normal charging operation of the charging vehicle. The utility model has a high degree of automation and a good dust collecting effect, improves the production workshop environment, and protects the occupational health of the staff.

[0014] Figure 4 It is a top view of the feeding trough of the utility model;

[0015] In the figure, there are a feeding pot 1, a feeding trough 2, an infrared transmitter 3, an infrared receiver 4, a PLC controller 5, a solenoid valve 6, a cylinder 7, a dust collecting flue 8, a dust collecting hood 9, a dust collecting pipe 10, a support rod 11, a sealing ring platform 12, a limit platform 13, a sealing pad 14, and a fan 15. Specific implementation method:

[0016] like Figure 1 As shown, a dust collecting device for a vacuum furnace charging pot comprises a charging pot 1, a charging trough 2 is installed on the charging pot 1, a lifting dust collecting hood device is installed above the charging trough 2, the lifting dust collecting hood device is connected to a dust collecting flue 8, and a fan 15 is installed in the dust collecting flue 8; the lifting dust collecting hood device comprises a dust collecting hood 9, a dust collecting pipe 10 is vertically connected to the dust collecting hood 9, the dust collecting pipe 10 is slidably connected to the dust collecting flue 8, and a cylinder 7 is vertically installed on the outer wall of the dust collecting flue 8, and the piston rod of the cylinder 7 is connected to the dust collecting hood 9.

[0017] like Figure 3 and Figure 4 As shown, an infrared radiation device is installed on the feeding trough 2, and the infrared radiation device is electrically connected to the PLC controller 5, and the PLC controller 5 is electrically connected to the solenoid valve 6, and the solenoid valve 6 controls the opening and closing of the cylinder 7; the infrared radiation device includes an infrared transmitter 3 and an infrared receiver 4, and support rods 11 are connected to the outer walls on both sides of the feeding trough 2, and the infrared transmitter 3 and the infrared receiver 4 are installed on the support rods 11, and the infrared receiver 4 is electrically connected to the PLC controller 5.

[0018] like Figure 2 As shown, a limit platform 13 is provided at the top of the dust collecting pipe 10, and the limit platform 13 is slidably connected to the inner wall of the dust collecting flue 8. A sealing ring platform 12 is connected to the bottom end of the dust collecting flue 8, and a sealing gasket 14 is installed on the sealing ring platform 12; the dust collecting flue 8 and the sealing ring platform 12 are connected by bolts, and the dust collecting flue 8 and the dust collecting pipe 10 can be disassembled by removing the bolts, so as to facilitate replacement and maintenance.

[0019] When doing specific work, such as Figures 1 to 3 As shown, when the feeding pot 1 is cooking, the infrared receiver 4 normally receives the infrared signal emitted by the infrared transmitter 3, and the infrared receiver 4 sends a signal to the PLC controller 5. The PLC controller 5 controls the solenoid valve 6 to open, the piston rod of the cylinder 7 to push out, and the dust hood 9 to descend to collect dust (at this time, the sealing ring 12 squeezes the sealing gasket 14 to complete the sealing); when the feeding pot 1 is in the feeding state, the feeding cart blocks the infrared signal emitted by the infrared transmitter 3. At this time, the infrared receiver 4 sends a signal to the PLC controller 5, and the PLC controller 5 controls the solenoid valve 6 to close, the piston rod of the cylinder 7 to retract, and the dust hood 9 to rise, which does not hinder the normal feeding operation of the feeding cart.
