Abstract
The invention discloses a pre-oxidation furnace with an air uniformizing structure. The pre-oxidation furnace comprises a furnace body, wherein two ends of the furnace body are provided with a feeding hole and discharging hole respectively; an air inlet and an air outlet are formed in the furnace body and on the lower side of the feeding hole and the upper side of the discharging hole respectively; the inner wall of the furnace body is provided with an air inlet channel and an air outlet channel which are communicated with the air inlet and the air outlet respectively; the air inlet channel corresponds to the air outlet channel. The pre-oxidation furnace disclosed by the invention is novel is structural design. Due to the design of the air inlet and the match of the air inlet channel with partition plates therein, the air flow entering a hearth of the pre-oxidation furnace can move longitudinally and stably, and the air flow can not take away broken filaments after passing through the hearth of the pre-oxidation furnace and coming out of the air outlet channel, thus the processing quality and processing efficiency can be improved.
Description
Technical field:
The present invention relates to the carbon fibre producing facility field, relate in particular to a kind of pre-oxidation furnace device with even wind structure.
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.
How designing a kind of structure and can guarantee air-flow traveling comfort in burner hearth, can guarantee that again the fracture of wire in the tow running can not taken away from the gas outlet with air-flow, is the technical problem that needs to be resolved hurrily at present.
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 device with even wind structure, structural design is simple, has guaranteed that air-flow operates steadily in the burner hearth, also the fracture of wire that produces in the tow running can be retained in the burner hearth.
Technical scheme of the present invention is as follows:
A kind of pre-oxidation furnace device with even wind structure, comprise body of heater, it is characterized in that: the two ends of described body of heater are respectively equipped with charging aperture and discharging opening, be equipped with air inlet, air outlet on the body of heater of charging aperture and discharging opening upper and lower sides, described inboard wall of furnace body is provided with air intake passage, the air-out passage with air inlet, air outlet difference UNICOM, and air intake passage is relative one by one with air-out passage.
Described a kind of pre-oxidation furnace device with even wind structure, it is characterized in that: it is rectangular housing that described air intake passage adopts the cross section, is provided with level and dividing plate spaced apart in the air intake passage.
Described a kind of pre-oxidation furnace device with even wind structure, it is characterized in that: described air-out passage is made of the conical shell of rectangular housing and front end, rectangular housing and the sealing of conical shell junction, the upper and lower surface of conical shell is provided with airflow hole.
Advantage of the present invention is:
Structural design of the present invention is novel, vertically steadily mobile by the air-flow that air inlet design air intake passage cooperates inner dividing plate to guarantee to enter in the burner hearth, enter air-flow in the burner hearth pass behind the burner hearth from air-out passage by after can not take away fracture of wire, improved quality and the efficient of processing.
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 device with even wind structure, comprise body of heater 1, the two ends of body of heater 1 are respectively equipped with charging aperture 2 and discharging opening 3, be equipped with air inlet 4, air outlet 5 on the body of heater of charging aperture 2 and discharging opening 3 upper and lower sides, body of heater 1 inwall is provided with air intake passage 6, the air-out passage 7 with air inlet 4, air outlet 5 difference UNICOMs, and air intake passage 6 is relative one by one with air-out passage 7.
It is rectangular housing that air intake passage 6 adopts the cross section, is provided with level and dividing plate 8 spaced apart in the air intake passage 6.
Air-out passage 7 is made of the conical shell 7-2 of rectangular housing 7-1 and front end, rectangular housing 7-1 and the sealing of conical shell 7-2 junction, and the upper and lower surface of conical shell 7-2 is provided with airflow hole 9.
