Technical Field

The invention relates to a furnace liner of a blackening furnace, in particular to a furnace liner of a mesh belt type continuous steam blackening furnace.

Background

In order to improve the corrosion resistance of the workpiece, it is required to perform a blackening treatment. Generally, a steam blackening treatment process is adopted, namely, the steam reacts with a workpiece under certain temperature and pressure conditions, so that a compact oxide film is generated on the surface of the workpiece, the oxide film has good antirust capacity, the surface hardness of the workpiece can be improved, and the wear resistance of the workpiece is improved. The mesh belt type continuous steam blackening furnace is furnace body equipment used in a steam blackening treatment process. The furnace inner container is used as a main accessory of the blackening furnace, and the internal structure of the furnace inner container plays an extremely important role in the whole blackening process.

The existing straight-through furnace liner ensures that the retention time of steam in the furnace liner is short, thus causing large steam usage amount in the production process. In the production process, the contact time of the steam and the workpiece to be processed is short, so that the energy consumption in the production process is increased.

Disclosure of Invention

The invention discloses a furnace liner of a mesh belt type continuous steam blackening furnace, which aims to solve the problems of short contact time and high energy consumption of steam and a workpiece to be processed.

Furthermore, an included angle is formed between the side wall baffle and the side wall, and is represented by alpha, wherein alpha is more than 0 degrees and less than 90 degrees, so that the side wall baffle is inclined to the discharge section of the mesh belt type continuous steam blackening furnace.

Preferably, 30 DEG-alpha is 75 deg.

Further, the number of the side wall baffles is n, and n is more than 0.

In one embodiment, n is an even number.

In another embodiment, 15 < n < 100.

Furthermore, n is more than 1, and the side wall baffles are alternately arranged at intervals on two sides of the furnace inner container.

Further, the furnace also comprises an upper baffle arranged at the top of the furnace inner container.

Furthermore, the upper baffle is V-shaped on the longitudinal section of the furnace inner container.

Furthermore, the number of the upper baffles is m, and m is more than 0.

The invention has the advantages that: the invention adopts the baffle plates arranged on the two sides and/or the upper part of the furnace inner container (which can be arranged in a welding way), so that the steam can be fully remained in the furnace inner container. In the production process, steam can be sucked away by a draught fan of the incinerator, and the two baffles (the side wall baffle and the upper baffle) enable gas in the incinerator to flow in a corrugated mode, effectively prolong the retention time of the steam in the inner container of the incinerator, enable the steam to be in contact with a workpiece more fully, improve the efficiency and save energy.

The present invention will be further described with reference to the accompanying drawings to fully illustrate the objects, technical features and technical effects of the present invention.
