Description

Technical Field

[0001] The utility model relates to the technical field of forging processing, in particular to a tungsten-molybdenum forging heating furnace. Background Art

[0002] When tungsten and molybdenum are forged and processed, they need to be heated first and then forged. Tungsten and molybdenum react with oxygen and air to form tungsten trioxide and molybdenum trioxide. These oxides themselves are not gases, but if they form fine particles (such as smoke) at high temperatures, they may cause certain harm to the human respiratory system.

[0003] The existing treatment method is to use activated carbon to filter these flue gases. However, when the activated carbon plate directly contacts high-temperature gas, if the temperature exceeds its heat-resistant temperature range, the activated carbon plate may undergo thermal cracking or oxidation reaction, resulting in the destruction of its pore structure and the reduction of specific surface area, thus affecting its adsorption performance and catalytic performance. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tungsten-molybdenum forging heating furnace to solve the above problems, as described in detail below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] The tungsten-molybdenum forging heating furnace provided by the utility model includes a base, an electric heating furnace is arranged on the base, and an air inlet pipe is arranged on the electric heating furnace for external air to enter the electric heating furnace.

[0007] A suction fan is arranged on the base for pumping out the air in the electric heating furnace. The air inlet end of the suction fan is communicated with the electric heating furnace. A water tank and an activated carbon tank are arranged on the base. The air outlet end of the suction fan is communicated with the water tank, and the water tank is communicated with the activated carbon tank through a pipeline.

[0008] By using the above tungsten-molybdenum forging heating furnace, the flue gas inside the electric heating furnace is pumped into the water tank by the suction fan. The water tank is filled with cooling water. The cooling water can absorb some solid small particles in the flue gas and reduce the temperature of the flue gas at the same time. After the flue gas passes through the water tank, it enters the activated carbon tank, and the harmful gases in the flue gas are absorbed by the activated carbon tank and then discharged to the outside.

[0009] Preferably, a water level sensor is arranged inside the water tank for detecting the water volume in the water tank.

[0010] Preferably, a water-cooled radiator is arranged on the water tank, and the water-cooled radiator is communicated with the water tank.

[0011] Preferably, an exhaust pipe is arranged on the activated carbon tank.

[0012] Preferably, a one-way valve is provided inside the ventilation pipe.

[0013] Preferably, the surface of the electric heating furnace is covered with heat-insulating tiles.

[0014] Preferably, a debris collection assembly is provided at the bottom of the inner wall of the electric heating furnace for collecting debris generated when heating tungsten and molybdenum materials.

[0015] Preferably, the debris collection assembly includes two guide rods. The two guide rods are fixedly arranged inside the electric heating furnace in parallel along the length direction of the electric heating furnace. A collection hopper is slidably arranged between the two guide rods, and a handle is arranged on the collection hopper.

[0016] The beneficial effects are as follows:

[0017] 1. The smoke inside the electric heating furnace is drawn into the water tank by a suction fan. The water tank is filled with cooling water. The cooling water can absorb some solid particles in the smoke and reduce the temperature of the smoke at the same time, avoiding the direct contact between the smoke and the activated carbon tank and causing damage to it, resulting in a reduction in the adsorption efficiency of the activated carbon tank.

[0018] 2. By providing a debris collection assembly to collect the debris generated when heating tungsten and molybdenum materials, it is avoided that these debris fall into the inside of the electric heating furnace and are not easy to clean. BRIEF DESCRIPTION OF THE DRAWINGS
