Automatic feeding mechanism for tungsten carbide heating reduction furnace

Abstract

The invention provides an automatic feeding mechanism for a tungsten carbide heating reduction furnace. The automatic feeding mechanism for the tungsten carbide heating reduction furnace comprises a conveying device, a weighing and discharging device, a smoothing device, a boat stacking device, a lifting device, a boat pushing device and a heating reduction furnace, wherein the conveying device, the weighing and discharging device, the smoothing device, the boat stacking device, the lifting device, the boat feeding device and the heating reduction furnace are arranged in sequence. The conveying device is used for receiving boats and conveying the boats to the subsequent device. The boats are provided with the upper boat and the lower boat. Footstands are arranged on two sides of the bottomof the upper boat, supporting seats are arranged on two sides of the top of the lower boat, the weighing and discharging device is used for receiving and weighing tungsten powder and discharging thetungsten powder into the boats, the smoothing device is used for smoothing the tungsten powder in the boats, the boat stacking device is used for stacking the upper boat to the lower boat, the liftingdevice is used for lifting the boats to the boat sending device, and the boat pushing device is used for pushing the boats into the heating reduction furnace. The automatic feeding mechanism for thetungsten carbide heating reduction furnace has reasonable structural design and high degree of automation, realizes an efficient, high-quality, and safe feeding process of the heating reduction furnace, the production efficiency is effectively improved, the labor intensity of personnel is reduced, and hidden safety dangers to personnel is avoided.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to an automatic feeding mechanism for a tungsten carbide heating reduction furnace. Background technique [0002] Before the tungsten powder enters the reduction furnace, it needs to be unloaded, weighed, loaded into a boat, and then pushed into the reduction furnace for heating. The existing technology is to manually pour the tungsten powder into the silo, weigh it automatically, and then manually weigh it. After the material is poured into the boat, it is raked manually, the upper and lower boats are stacked manually, and pushed to the furnace door, and the boat is placed on the pushing rack manually, and then the boat is automatically pushed into the recovery by the boat pushing equipment. In the furnace tube of the furnace; at the outlet of the furnace, the boat is pulled out manually, and after the material is poured, the boat is dragged back to the weighing and loadi...

AI Technical Summary

Problems solved by technology

Existing operations are completed automatically except for weighing and pushing the boat, and the others are all done manually, which leads to high labor intensity, low work efficiency, and poor product quality, and due to the characteristics of tungsten powder, there is a risk of inhalation when personnel take it.
