Abstract
The present invention belongs to a device for producing float glass, and provides a pressure stabilizing device on a cooling part of a melting kiln of a production line of float glass. The device has a structure that a pair of chimneys (2) are respectively arranged on both sides of the cooling part; a wind pipe (3) on the top end of each chimney (2) is connected with a blower (6), the inner walls of an annular wind inflow channel of the blower (6) are provided with a plurality of wind outflow holes (4) which are arranged around; an adjusting valve (5) for controlling and adjusting wind inflow quantity and a pressure measuring pipe (7) for measuring the pressure of the kiln are arranged. With the advantages of reasonable and simple structural design and convenient operation, the pressure stabilizing device of the present invention can be used for conveniently realizing stabilization of the kiln pressure on the cooling part, and each technological parameter can be kept stable, so that the requirement for forming the glass with high quality can be met.
Description
Affiliated technical field
The invention belongs to float glass equipment, what relate generally to is a kind of stable-pressure device of floatation glass production line melting furnaces cooling end.
Background technology
At present, in domestic most of float glass, mainly be to rely on the last flame and dilution wind to regulate the cooling end furnace pressure to port, and during changing fire, the furnace pressure of cooling end can produce fluctuation, thereby makes every processing parameter of cooling end change, and causes the fluctuation of glass quality, and the furnace pressure of cooling end can only measure demonstration at present, can't carry out automatic control and adjustment.Especially when thin glass and ultra-thin glass production, stability requirement to every processing parameter of melting furnaces cooling end is higher, as not keeping the stable of melting furnaces cooling end, keep the stable of every processing parameter thus, the quality of its glass production will be subjected to very big influence, thin glass and ultra-thin glass are used for purposes such as display panel after further processing treatment, its every performance index are had relatively high expectations.
Summary of the invention
The objective of the invention is to propose a kind of stable-pressure device of floatation glass production line melting furnaces cooling end, the furnace pressure of melting furnaces cooling end is regulated control, thereby make the processing parameter of cooling end keep stable, satisfy the needs of high quality float shaping.
Its structure design of stable-pressure device that the present invention proposes is: the both sides at cooling end respectively are provided with a pair of chimney, the vertical airduct of chimney is connected with blower fan, the inwall of its annular air inlet duct has a plurality of air outlet openings of arranging in ring week, the piezometric tube of measuring the cooling end furnace pressure is set and the variable valve of regulating and controlling to the airduct air intake is set.The wind that blower fan provides is transported in the airduct by variable valve, be blown in the chimney by air outlet opening, when blast that increases chimney top airduct air outlet opening and air quantity, just formed air curtain one,, improved the furnace pressure of cooling end thus substantially with the top closure of chimney, and when reducing its blast of air outlet opening of airduct and air quantity, just can reduce the furnace pressure of cooling end, variable valve is connected by pilot circuit with piezometric tube, just can make the furnace pressure of cooling end be regulated control automatically.
The stable-pressure device reasonable in design that the present invention proposes is simple, uses operation comparatively easy, can realize the stable of cooling end furnace pressure comparatively easily, makes its every processing parameter keep stable, thereby satisfies the needs of high quality glass moulding.
Description of drawings
Accompanying drawing 1 is user mode synoptic diagram of the present invention.
Accompanying drawing 2 is the structural representation of airduct of the present invention.
Among the figure, 1, the glass melter cooling end, 2, chimney, 3, airduct, 4, air outlet opening, 5, variable valve, 6, blower fan, 7, piezometric tube, 8, control section.
Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiments of the invention:
As shown in drawings, its structure design of stable-pressure device that the present invention proposes is: a pair of chimney 2 (only providing the signal of a side chimney among the figure) respectively is set in the both sides of melting furnaces cooling end, the lower end of chimney 2 is communicated with cooling end, the top of chimney 2 has airduct 3, airduct 3 is connected and is provided with the variable valve 5 of control blast and air quantity with blower fan 6, the inwall of airduct 3 its annular air inlet ducts has a plurality of air outlet openings 4 of arranging in ring week, be provided for measuring the piezometric tube 7 of cooling end furnace pressure, furnace pressure by piezometric tube 7 demonstrations, manual regulation variable valve 5, can pass through blast, the air quantity size improves or reduces furnace pressure, and piezometric tube 7 is the existing matured product of present widespread usage.As piezometric tube 7 is connected with Fan Regulation valve 5 by control section, can realize automatic control to furnace pressure, adopt micro-chip as control section, the furnace pressure that piezometric tube 7 records enters micro-chip by input interface, micro-chip by 5 actions of Output Interface Control variable valve, is regulated the blast of air intake and the size of air quantity after treatment.This control section is simple, a most the most frequently used present control techniques, does not do too much explanation at this.
