Abstract
The utility model relates to an annealing furnace used for the glass product industry. A combustion chamber is upper burning type, the heat of which is supplied by the concentrated fuel injection of a burner nozzle. The heat of the combustion chamber is uniformly supplied to the working space in the furnace by a flow injection opening to enable the glass product to obtain anneal; then, the waste gas passes through a kang surface and a fire passing path to be discharged into the outside by a flue. The utility model has the advantages of compact and simple structure, small volume, obvious energy saving, high heat efficiency and convenient repair; in addition, the anneal quality of the glass product is improved; thus, the utility model is an ideal furnace for the glass product industry.
Description
The utility model belongs to a kind of low-temperature industrial stove, particularly is used in the little energy of the upper burning type semi-flaming annealing of glassware stove in the glass product.
All annealed in the glasswork, to eliminate the internal stress that glasswork is produced in the moulding chilling, its method is: glasswork is put into annealing furnace be heated to annealing point, then cooling.At present, external most of lehr, the inductance of employing, coal gas are fuel, and part third world countries adopt oil to do fuel, and the combustion chamber of this annealing of glassware stove is arranged in the guipure below, by two brunched burner nozzle both sides heat supplies.The semi-flaming annealing of glassware stove that China glasswork manufacturer uses, its fuel is heavy oil, the combustion chamber also be provided in a side of guipure below, heavy oil is after the internal combustion of combustion chamber, fuel Products enters working space (referring to the guipure top) by the both sides of furnace chamber, like this, cause the transverse section thermograde of working space big, thermo-efficiency is low.The a heatable brick bed face brick of combustion chamber was at high temperature worked after for some time, and the damage that is easy to break when this phenomenon takes place, has only will guipure to disconnect the back and extract holder row, the guide rail of the holder net of dismantling out.Could repair a heatable brick bed face, re-assembly again after the repairing and reset, thus maintenance trouble very.In addition, this annealing furnace day the expendable weight oil mass generally at 400～800kg/D, so little fuel charge, the heavy oil oneself viscosity is big in addition, 200
#Heavy oil is when being heated to more than 104 ℃, could spray by burner, thereby fuel charge is difficult to control, has only and adopts the central heating form, can alleviate this problem, yet, adopt the semi-flaming annealing of glassware stove of heavy oil central heating, the unusual ideal structure formation of none still both at home and abroad at present is to be implemented under the central heating condition, not only energy-conservation but also reduce the transverse section thermograde, and easy to maintenance.
The purpose of this utility model just provides a kind of in the processing requirement that satisfies the semi-flaming annealing of glassware, adopt the mode of central heating reach energy consumption low, reduce working space transverse section temperature, upper burning type semi-flaming easy to maintenance is little can the annealing of glassware stove.
This annealing of glassware stove is achieved in that and at first changes existing furnace construction, changes the combustion chamber of stove into burning by burning down, and with the concentrated oil jetting combustion heat supply of a burner.The combustion chamber is located at working space top in the stove, and the rear end, combustion chamber is provided with burner, oil spout in the combustion chamber, and hot gas flow will spray to working space in the stove equably by the flow jeting port that the bottom, combustion chamber is provided with, to being placed on the glasswork heating anneal on the guipure.In addition, the bottom of working space in stove (bottom of guipure) is provided with away quirk (exhaust passage), and the end of walking quirk is provided with and the outdoor flue that communicates, and discharges the waste gas that flows through glasswork and upper and lower layer guipure outdoor.
The utility model has the advantages that: 1. owing to designed the structure of reasonable stove shape and combustion chamber, heat-processed has been divided into the combustion zone, spray, chokes district, hot gas flow is evenly flowed downward in the guipure lateral extent, reduce transverse temperature gradient in the stove, therefore helped improving the annealing quality of product.2. because the guipure homogeneous heating makes the thermal expansion of guipure even, avoided the on-mechanical performance sideslip of guipure, improved the reliability of transmission system, belt life is improved.3. the bottom of combustion chamber, owing to be provided with a bigger flow jeting port, so when being damaged in the combustion chamber, need not tear any position open, the serviceman can directly enter and keep in repair, and has reduced maintenance cost and servicing time.4. because of having adopted the structure of returning the inoperative band in the stove, and below whole guipure, be provided with away quirk (walking quirk down).So hot gas flow is successively by behind the glasswork and upper and lower guipure that are placed on guipure, enters away quirk and discharge outdoor through flue.So just make and return guipure and utilize waste heat, make preheating temperature approach to enter the temperature of the glasswork of annealing furnace, reduced bursting of glasswork, improved product percent of pass by fully preheating.Make full use of thermal source, improved thermo-efficiency, saved the energy.5. owing to adopt a upper burning type combustion chamber to concentrate the structure of downward heat supply, make whole furnace construction compactness, volume-diminished, the scene that is beneficial to the user is arranged.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
Accompanying drawing 1 is a theory structure positive view of the present utility model.
Accompanying drawing 2 is structure positive views that amplify combustion chamber of the present utility model.
With reference to accompanying drawing 1,2, its structure is, above the front end, promptly the top of working space in the stove is provided with a upper combustion chamber (1) at body of heater (7), and the aft end face of this combustion chamber is provided with a burner (6), by burner oil spout in the combustion chamber.Be provided with the metope (4) of a hole, graticule mesh shape in the combustion chamber, its combustion chamber combustion zone (5) and spray, chokes district (2) have been divided into, be provided with flow jeting port (3) at spray, position, chokes district, this flow jeting port is made of hole that differs in size and seam, make hot gas flow after the burning by flow jeting port, spray into working space (furnace chamber) (10) equably.In furnace chamber, adopt the frame mode that returns the inoperative guipure in the stove, a strip metal guipure (11) is set, the upper strata is the working order guipure, lower floor is that off working state is returned guipure, turns round by motor, deflector roll, guide wheel etc.(stove in working space following) is provided with away quirk (12) below the guipure, and a heatable brick bed face of walking quirk is provided with hole seam bonded exhaust outlet (9), and the both sides of walking the quirk end are provided with inner flue (8) and communicate with outdoor smokestack.
