Problems solved by technology

The existing furnace door device is connected and rotated by a single hinge, and the other side is fixed with a rotary handle lock. When the furnace door is opened, due to the weight of the furnace door, manual opening is labor-intensive. It will cause wear and tear on the refractory body of the furnace door; and the refractory body of the furnace door is large in size and high in temperature. After the furnace door is opened, some employees will occupy the operating space for dredging and cleaning the flue gas pipeline, which poses a safety hazard. When the furnace door is closed, due to the pressure in the secondary combustion chamber The higher furnace door will automatically pop open and the smoke will overflow

Abstract

The invention relates to the field of precious metal smelting equipment, and in particular, relates to the field of recovery of precious metal by using a plasma smelting furnace. A secondary combustion chamber furnace door device of a precious metal recovery plasma furnace comprises a furnace door (1) for covering a furnace port; the furnace door (1) consists of a hollow furnace door (2) and a refractory body (3); the refractory body (3) is arranged on the inner side of the hollow furnace door (2); a cooling water inlet (4) is formed in the lower part of the outer side of the hollow furnace door (2); and a cooling water outlet (5) is formed in the upper part of the outer side of the hollow furnace door (2). The secondary combustion chamber furnace door device of the precious metal recovery plasma furnace further comprises a rotating shaft mechanism (6), a side positioning plate (7), a lower positioning plate (8), a slide system (9) and a fixture (10); and the slide system (9) consists of a rail (11) and a slide wheel (12). The secondary combustion chamber furnace door device of the precious metal recovery plasma furnace can guarantee the plasma smelting furnace to clean a flue in the precious metal smelting process, prevents potential safety hazards, guarantees enough operation space, reduces the labor intensity, guarantees the personal safety, reduces the heat loss, and protects the environment.

Description

technical field [0001] The invention relates to the field of precious metal smelting equipment, in particular to the field of recycling precious metals by using a plasma smelting furnace. Background technique [0002] Plasma is a controllable, clean, high-temperature multifunctional heat source, which has the advantages of high energy density, fast material reaction speed, and controllable atmosphere. It is used in hazardous waste treatment, waste power generation, precious metal recycling and other industries. Plasma smelting technology has the advantages of small proportion of ingredients, high recovery rate of precious metals, large batch processing capacity, continuous feeding and discharging, low energy consumption, and less environmental pollution. It has been widely adopted by world-renowned precious metal companies. [0003] The exhaust gas from the plasma furnace enters the second combustion chamber from the bottom of the second combustion chamber, and the burner i...
