Glass electric melting furnace is a common equipment for melting glass, the existing electric melting furnace chamber surrounded by refractory insulation material, the upper part of the chamber has a supply port, the lower part of one end has a discharge outlet, the middle of the chamber is installed on both sides of the electrode. When the electrodes are energized, a high current is generated, which can melt the glass material in the furnace chamber. In order to prevent the discharge of molten glass when cooling too quickly and bonding, the discharge outlet is also equipped with a flame heater and radiation electric heating rod near. However, in use, either the flame heater or the radiation electric heating rod, due to the large thermal inertia, it is difficult to achieve the ideal discharge temperature control in a timely manner. The result is that the glass is discharged at too high a temperature and flows too fast, often making it difficult to carry out processing operations. So, let’s learn how to make an electric glass melting furnace together below!
At present, the glass products production industry at home and abroad in order to adapt to energy-saving and environmental protection policies, production methods more than the use of glass electric melting production methods, glass electric melting furnace with electricity as the main energy source, replacing the traditional coal-fired, oil products and other flame melting furnace. Glass melting into the manual pick-up pool, the need to use the glass liquid electrode heating proportional to the space of silicon carbon rod or silicon molybdenum rod heating method to ensure the quality of materials, waste of manpower and material resources.
Glass electric melting furnace technology to achieve elements.
Glass electric melting furnace in order to overcome these shortcomings of the prior art, the invention provides a reasonable structure, economical and practical, easy to operate glass electric furnace. In addition, the glass electric furnace discharge temperature adjustment is sensitive, the flow of discharged glass is adjustable, and multiple discharge channels and discharge ports are provided instead of manual discharge pools to speed up the discharge process.
In order to solve the above-mentioned problems, the invention has a furnace body, in the front and central part of the inner chamber of said furnace body is set up melt pool, clarifier pool, in the rear part of the inner chamber of said furnace body is set up rise road, main material channel, and separation road, in the upper end of said melt pool is set up supply port, said melt pool and clarifier pool through the first liquid hole said rise road lower end and the bottom of the clarifier pool through the second liquid hole connected, said rise road The upper end of said rising path is connected to one end of the main sprue, a number of branch paths are connected on both sides of said main sprue, a discharge outlet is provided on the furnace wall below the end of said main sprue and branch paths, a heating element is provided on the furnace body corresponding to the position of said discharge outlet, a temperature sensor and a flow rate switch are provided at said discharge outlet, two sets of electrodes are provided in said melt cell and clarifier respectively, two sets of electrodes are provided in said melt cell, clarifier, main sprue and branch path respectively. and branch channels are provided with two sets of electrodes respectively.
In the above-mentioned manner, said main flow path and sub-flow path have a positive octagonal cross-section.
in the above manner, a refractory layer and an insulation layer are provided in the outer layer of said furnace body in turn
in the above-mentioned manner, said bottom of said melt pool and clarifier is of chamfered construction
in the foregoing manner, an exhaust port is provided in the upper part of said melt cell and clarifier
in the foregoing manner, said electrode is a molybdenum electrode and said heating element is a silicon carbon rod.
In the foregoing technology, said furnace body is made of zirconium corundum bricks.
The beneficial effects of the electric glass melting furnace are as follows.
1, the glass electric melting furnace body external set refractory layer and insulation layer, to prevent heat dissipation, effective energy saving, the bottom of the pool chamfering structure to prevent the glass liquid in the edge temperature uneven bonding, to avoid the melt block affect the quality of glass materials.
2. The invention designs temperature sensors and heating elements at the spray to regulate the discharge temperature respectively, and designs flow switches to control the glass flow to meet the different discharge speeds of the required liquids to ensure various glass forming needs.
3. The main and sub-paths adopt a positive octagonal furnace structure is to facilitate the convergence of glass liquids. In addition, heating elements are provided in the main and sub-passages to prevent the glass liquor from bonding due to temperature reduction and to ensure that the glass liquor flows out from the sub-passages. The design of multiple sub-passages and discharge outlets for the main and sub-passages allows for multiple forming moulds to be put in at the same time, replacing the manual pick-up pool, speeding up the pick-up process and saving manpower.
