Abstract
The invention discloses an air inlet collector for a hearth of a pre-oxidization furnace. The air inlet collector comprises a box body, wherein the front and rear ends of the box body are open; one end is an air inlet end, and the other end is an air outlet end; a clapboard is arranged in the middle of the box body, so that the box body is divided into an air supply cavity close to the air inlet end, and a regulating cavity close to the air outlet end; multiple air supply holes are uniformly distributed in the clapboard; multiple slots are distributed on the clapboard at intervals; insertion plates are inserted into the multiple slots in a sliding mode; and the insertion plates are parallel to each other. The air inlet collector is reasonable in structural design, airflow flows parallel to the operating direction of the tows, and the phenomenon that a large turbulence area is caused in a heat treatment cavity due to hot air flow is avoided, so that wire breakage and fuzziness of tows due to generation of the turbulence area are effectively avoided.
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 intake summary device.
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 inlet structure design in original burner hearth, can not guarantee the uniformity of air-flow, therefore, also just can not guarantee the uniformity of temperature, flowed by hot gas and cause large disorder district in hot processing chamber inside, the generation in disorderly district and the fracture of wire and the tow fluffing that occur have a strong impact on the crudy of product.
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 intake summary device, structural design is novel, can effectively guarantee to enter the uniformity of the air-flow in the burner hearth.
Technical scheme of the present invention is as follows:
A kind of pre-oxidation furnace burner hearth air intake summary device, comprise casing, it is characterized in that: the rear and front end of described casing is uncovered, wherein an end is air intake, and the other end is outlet air end, and the middle part of casing is provided with dividing plate casing is divided into the wind pushing cavity near air intake, the adjusting chamber of close outlet air end, be evenly distributed with several wind pushing holes on the described dividing plate, be intervally distributed with several slots on the dividing plate, all sliding in several slots is interspersed with plate, is parallel to each other between the plate.
Described a kind of pre-oxidation furnace burner hearth air intake summary device, it is characterized in that: described several wind pushing holes are circular hole, the two ends of circular hole are horn-like.
Described a kind of pre-oxidation furnace burner hearth air intake summary device, it is characterized in that: the inwall of described casing is provided with the nanometer high-temperaure coating, and the thickness of nanometer high-temperaure coating is not less than 50 μ m.
Described a kind of pre-oxidation furnace burner hearth air intake summary device, it is characterized in that: the height of described casing is at 70～80mm, and width is at 190～210mm.
Advantage of the present invention is:
Reasonable in design of the present invention, air-flow are parallel to the tow traffic direction and flow, and have prevented that hot processing chamber inside from causing large disorder district by hot gas is mobile, thereby have effectively prevented the generation that disorder is distinguished and the fracture of wire that occurs and tow fluffing.
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 intake summary device, comprise casing 1, the rear and front end of casing 1 is uncovered, wherein an end is air intake 2, the other end is outlet air end 3, the middle part of casing 1 is provided with the wind pushing cavity 5 that dividing plate 4 is divided into casing 1 close air intake, adjusting chamber 6 near outlet air end, be evenly distributed with several wind pushing holes 7 on the dividing plate 4, be intervally distributed with several slots 8 on the dividing plate 4, several slot 8 interior all slips are interspersed with plate 9, are parallel to each other between the plate 9, can be according to actual conditions, select quantity or the spacing of the plate 9 of insertion, regulate the uniformity that enters air-flow in the burner hearth thereby can reach.
Several wind pushing holes 7 are circular hole, and the two ends of circular hole are horn-like.
The inwall of casing 2 is provided with nanometer high-temperaure coating 10, and the thickness of nanometer high-temperaure coating 10 is not less than 50 μ m.
The height of casing 1 is at 70～80mm, and width is at 190～210mm.
