Abstract
The invention discloses an air outlet collector for a hearth of a pre-oxidization furnace. The air outlet collector comprises a shell of which the section is rectangular, wherein an air inlet shell of which the section is pointed conical is arranged at the front end of the shell; the joint of the air inlet shell and the shell is sealed; the upper and lower surfaces of the air inlet shell are arc-shaped surfaces, and collection holes are uniformly distributed in the upper and lower surfaces of the air inlet shell; and center lines of the collection holes are arranged along the horizontal direction. The air outlet collector is reasonable in structural design, the pointed conical air inlet shell is connected with the shell, and the collection holes are designed on the upper and lower arc-shaped surfaces of the air inlet shell, so that a broken wire can be prevented from entering a cavity between a hot air shell and the air inlet shell; and therefore, the broken wire easily returns into the tows when the tows are operated, waste of raw materials is reduced, and the quality of the working environment is guaranteed.
Description
Technical field:
The present invention relates to carbon fibre producing facility, relate in particular to a kind of pre-oxidation furnace burner hearth air-out manifold.
Background technology:
The pre-oxidation furnace specialized designs is applied to carbon fibre material in the usefulness of carrying out high-temperature heat treatment below 350 ℃, and as raw material, in process, the gas flow temperature uniformity in the burner hearth seems particularly important for the precursor of the oxidized fibre used of preparation carbon fiber.
There is defective in air exhausting structure design in original burner hearth, in the time can guaranteeing the uniformity of air-flow, the fracture of wire that produces when following the tow operation in the process of air-out is directly taken away, and causes on the one hand the waste of raw material, is suspended on the other hand the pollution that causes environment in the air.
Summary of the invention:
In order to remedy the prior art problem, the purpose of this invention is to provide a kind of pre-oxidation furnace burner hearth air-out manifold, structural design is simple, can so that tow when operation the fracture of wire that produces directly get back on the tow, can not cause environmental pollution.
Technical scheme of the present invention is as follows:
A kind of pre-oxidation furnace burner hearth air-out manifold, it is characterized in that: comprise that the cross section is rectangular housing, the front end of described housing is provided with the air intake shell that the cross section is sharp cone distal, air intake shell and the sealing of housing junction, the upper and lower surface of air intake shell is arcwall face and is evenly distributed with and compiles the hole, compiles the center line along continuous straight runs in hole.
Described a kind of pre-oxidation furnace burner hearth air-out manifold is characterized in that: the length of described air intake shell is at 140～160mm, and height is at 70～80mm.
Described a kind of pre-oxidation furnace burner hearth air-out manifold, it is characterized in that: the height of described housing is at 70～80mm.
Described a kind of pre-oxidation furnace burner hearth air-out manifold, it is characterized in that: the inwall of described air intake shell and housing and outer wall are respectively equipped with high-temperaure coating, the smooth ceramic coating that the nanometer exotic material is made, and the thickness of high-temperaure coating, smooth ceramic coating all is not less than 65 μ m.
Advantage of the present invention is:
Reasonable in design of the present invention, air intake shell by sharp cone distal is connected with housing, and compile the hole in the design of the up and down arcwall face of air intake shell, can prevent that fracture of wire from entering in the cavity between hot gas housing and the air intake shell, so that being easy to get back in the tow, goes tow when operation fracture of wire, reduce the waste of raw material, also guaranteed the quality of working environment.
Description of drawings:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
Referring to Fig. 1:
A kind of pre-oxidation furnace burner hearth air-out manifold, comprise that the cross section is rectangular housing 1, the front end of housing 1 is provided with the air intake shell 2 that the cross section is sharp cone distal, air intake shell 2 and the sealing of housing 1 junction, the upper and lower surface of air intake shell 2 is arcwall face and is evenly distributed with and compiles hole 3, compiles the center line along continuous straight runs in hole 3.
The length of air intake shell 2 is at 140～160mm, and height is at 70～80mm.
The height of housing 1 guarantees that at 70～80mm overall dimensions is within zone of reasonableness.
Air intake shell 2 is respectively equipped with high-temperaure coating 4, the smooth ceramic coating 5 that the nanometer exotic material is made with inwall and the outer wall of housing 1, the thickness of high-temperaure coating 4, smooth ceramic coating 5 all is not less than 65 μ m, during the tow operation, the fracture of wire that produces finally can be got back on the tow in air intake shell 2 and the rapid landing of housing 1 outer surface.
