Abstract
The present invention relates to a self-preheating type volumetric heating oven which adopts a horn-shaped oven chamber. Therefore, heating path and duration are prolonged. The present invention is favorable to guide the direction of heat flow and reduce heat waste, so heat efficiency is greatly improved. A swing tray B is adopted in the oven, so a volume and a heating area are expanded. The swing tray is matched with the horn-shaped oven chamber so as to realize the combination of preheating, heating and soaking. Heat efficiency is improved one times by using the present invention, and investment is saved by 50 percent. With the advantages of simpleness, high work rate, wide adaption, the present invention is applicable to gas, liquid, solid fuel, various blanks and various ovens. Heating ovens, annealing ovens, forging ovens, etc. can be replaced by the present invention which is particularly suitable for hot rolling.
Description
The present invention relates to the material heating furnace, especially metal material heating from the preheating volumetric heat oven.
The firing equipment that hot-rolling metal is used, particularly medium and small-scale material, silicon steel sheet, wire rod and various aluminium, copper material etc. adopt steel-pushing type mostly, roll end formula, the chain type heating furnace.This horizontal, linear pattern heating furnace,, operation inconvenience big, long in time limit except that investment, the maintenance difficult, the thermal efficiency not high (being generally about 25%) is a great technical barrier all the time.
United States Patent (USP) (US-345542) discloses a kind of thermal efficiency that improves, and reduces burning, and band rotates the heating furnace of siege.This patent attempts to replace fixing box type heater with the siege that trunnion axis or sloping shaft rotate, in the hope of improving the heating condition of forging and pressing blank.But, cause this invention to fail to obtain actual application and popularization because blank kind and size restrictions are big, heat energy utilization is insufficient, the complexity of furnace construction etc.
At the problems referred to above, the purpose of this invention is to provide a kind of simple in structure, volume is less, unit capacity is big, the thermal efficiency is higher, can adapt to many kinds, large scale material base, band rotate siege from the preheating volumetric heat oven.
For achieving the above object, the present invention has taked following scheme:
Setting has eccentric interior arch and outer arch, constitutes the scroll casing shape type of furnace, to adapt to the hot-fluid guiding.In the scroll casing shape type of furnace, the revolution charging tray around the trunnion axis running is set, to enlarge unit capacity, to strengthen heat absorption.At the big end of the type of furnace detachable fuel nozzle and the outlet of hot base are set, small end is offered the import of " cold " base, and makes the running of revolution charging tray backheating flow path direction, realizes preheating, heating, all heating integrated.Offer adiabatic trench in the body of heater bottom,, adapt to the needs of existing factory building to reduce heat waste, to reduce the body of heater total height.
The present invention is absorbed heat fully, heat waste is less, so the thermal efficiency greatly improves; Simple in structure, build easily, so expense is lower; Various fuel (gas, liquid, solid) are all applicable; The material base kind is not limit, thereby the scope of application is bigger.
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the front view of schematic diagram of the present invention.
Fig. 2 is the side view of schematic diagram of the present invention.
1. the scroll casing shape type of furnace (18)
In arch (3) center a, outer arch (2) center b respectively and between the center o of the driving shaft (8) of revolution charging tray (17), eccentric throw E and e are respectively arranged, thereby make the inner surface formation scroll casing shape type of furnace (18) of outer surface with the outer arch (2) of interior arch (3), its longitudinal projection is a class circular arc, and flow area is by diminishing greatly gradually.Experiment by the theory of similarity derives has confirmed that fully this type of furnace has prolonged be heated route and heated time, helps guiding hot-fluid to flow to, and reduce heat waste, thereby the thermal efficiency improves greatly.
Interior arch (3) places on the left and right sides inside wall (12), and outer arch (2) places on the left and right sides external wall (10), constitutes the aerial part of the scroll casing shape type of furnace (18) jointly.In arch (3) be the monoblock type splicing structure with outer arch (2) so as lifting, install more easy, thereby replace existing manual brickwork mode.
The under ground portion of body of heater is offered the trench (13) that the surface has heat insulation layer (14), passes through so that revolution charging tray (17) freely rotates, and reduces the body of heater height, reduces heat waste.
Except that single use, the scroll casing shape type of furnace (18) can a plurality ofly be connected, and its main points are that each type of furnace is end to end, all disposes corresponding revolution charging tray (17) in each stove.This profile is arranged and is resembled undate plural serial stage heating furnace, and particularly suitable circle cross section material base is as pipe, round steel etc.
In order to improve the thermal efficiency, on the inwall of external wall (10), the anti-torrid zone of projection (11) that adapts to interior arch (3) arc top is set, in order to reduce the hot-fluid loss, prolong the service life of member.Stove gone into by cold base and hot base is come out of the stove, and can adopt end face turnover, side turnover or its combination by the material base kind.
The toxic emission mode, the row's of selecting for use formula or lower-discharging type all can as required.
2. turn round charging tray (17)
Revolution charging tray (a 17) similar oversized wheel width of cloth bar formulas " external gear " have many uniform, isometric width of cloth bars (4), clamping ring (5) and flanges (6) etc. on it.
The part of clamping ring (5) is stretched out in " gear teeth " (7) of being somebody's turn to do " gear " for width of cloth bar (4)." root circle " is exactly clamping ring (5).Material base (15) can be deposited with " tooth paddy " (16) that " root circle " constitutes in " gear teeth " (7)." whole depth " h determines by every grade of material base total height, with do not collide interior arch (3), outer arch (2) exceeds." space width " S by material base thickness determine-" plate " class is in 2 times of thickness, square steel, pipe, section bar are in the single-piece effective thickness.
Flange (6) connects the flange of width of cloth bar (4) and driving shaft (8).
The structure of revolution charging tray (17), outside the spoke bar formula of getting on the bus, also available common ingot bar pin-connected panel or gear ring sleeve type distressed structure.The heated components surface of this charging tray can spray, lay the heatproof nonmetal material.
About revolution charging tray (17) each one, rotating speed is identical, turns to flow to opposite with hot-fluid.The material base technological requirement is pressed in its running and adjustment, is finished by mechanical type or fluid transmission type decelerator (9).When material base length more in short-term, also can only turn round charging tray (17) with one, still can keep stable operation.
After revolution charging tray (17) is set, realized that the space heats in turn, the batch of unit volume is greatly improved, the material base heating surface area also obviously increases, with cooperating of the scroll casing shape type of furnace (18), prolonged the heated time and the route that is heated, realized preheating,, heating, all heating integrated.
3. nozzle (1)
In order to adapt to variform fuel-as the needs of coal dust, natural gas, coal gas, heavy oil, nozzle (1) employing activity detachable, its quantity, position, spray angle etc. are determined by technology.
