Abstract
The invention discloses a skimming machine for producing ultra-thin glass. Skimming pools are outside one side wall or two side walls of the tail end of a tin bath; two impellers are respectively and transversally arranged in the skimming pools; one end or both ends of each impeller are arranged in each skimming pool through bearings; the outer ends of the two impellers are connected with a power part; a partition wall is arranged between the tin bath and each skimming pool; one side of each partition wall is provided with a tin inlet; the other side of each partition wall is provided with a tin outlet; and the upper edge of each tin inlet is higher than a tin liquor level, whereas the upper edge of each tin outlet is lower than the tin liquor level. A reducing motor can be adopted to serve as the power part and is controlled through a frequency converter. According to the skimming machine for producing the ultra-thin glass, tin liquor moves through the action of the impellers respectively arranged in the skimming pools, so that tin dross floating on the surface of the tin liquor flows from the tin bath to the skimming pools; the impellers are driven through the reducing motor, and the rotate speed of each impeller can be realized through regulating the frequency converter. The skimming machine for producing the ultra-thin glass is capable of reducing defects, such as volatile matter of the tin bath, and is favor of increasing the quality of the glass.
Description
Technical field:
The present invention relates to a kind of auxiliary facility of molten tin bath in the ultra-thin glass production process, be specifically related to a kind of slag removal machine of ultra-thin glass production usefulness.
Background technology:
The equipment of skimming of float tin groove mainly adopts linear electric motors at present, and the electromagnetic force that produces through the linear electric motors effect that is installed in the molten tin bath promotes the tin liquor motion, and the flow velocity of tin liquor and direction can realize through the adjustment parameter of electric machine.There is following problem in this mode: owing to be installed in the molten tin bath, and need to feed water coolant, easily at this equipment place deposition, condensation molten tin bath volatile matter, and then form the molten tin bath defective; Under the effect of linear electric motors, the tin liquor convection current is strong, and tin liquor surface temperature lack of homogeneity influences the glass surface quality.
Summary of the invention:
The present invention is directed to the problem that the equipment of skimming at present exists, propose a kind ofly to be used for ultra-thin glass production and to use slag removal machine.
The technical scheme that the present invention adopted: slag removal machine is used in a kind of ultra-thin glass production; In the terminal outer setting of a side or two side of the molten tin bath pond of skimming; Take off and be horizontally installed with impeller in the slag bath; One end of this impeller or two ends are installed in through bearing and take off in the slag bath, and the outer end of impeller is connected with power section; Said molten tin bath and take off partition wall is set between the slag bath, a side of this partition wall is provided with tin inlet, opposite side is provided with stannum export, said tin inlet for the upper edge that is higher than tin liquor face stannum export, upper edge be lower than the tin liquor face.Tin liquor produces motion through being installed in the impeller action of taking off in the slag bath, the scruff that swims in the tin liquor surface is flow to from molten tin bath take off slag bath, and impeller drives through reducing motor, and its rotating speed can be realized through the adjustment frequency transformer.
Power section comprises reducing motor and frequency transformer and unit, and an end of impeller directly or through shaft coupling and reducing motor is in transmission connection, and the control input end of reducing motor is connected with frequency transformer, and frequency transformer is connected with unit.
Said impeller comprises rotating shaft and blade, and blade is plane or cambered surface, and blade is fixed in the rotating shaft outside vertically, and this blade is stainless steel or ceramic refractory.
Unit adopts DCS control.
Tin inlet on the partition wall is positioned at downstream and stannum export is positioned at the upper reaches, and perhaps the stannum export on the partition wall is positioned at downstream and tin inlet is positioned at the upper reaches.
Useful positively effect of the present invention: it is mobile that this ultra-thin glass production adopts wheel rotation that tin liquor is produced with the equipment of skimming, and the scruff on tin liquor surface flows into tin liquor takes off slag bath, thereby reaches the purpose of cleaning scruff.Rotating speed through the adjustment impeller can be adjusted the flow velocity of tin liquor, and impeller drives through reducing motor, and reducing motor is connected to frequency transformer, can be through frequency transformer adjustment motor speed.
The impeller of slag removal machine is positioned at takes off slag bath, need not be installed in the molten tin bath, can reduce the generation of molten tin bath volatile matter; This slag removal machine makes tin liquor take place to flow through impeller action, and the reactive force of impeller is less, and the tin liquor flow velocity is slow, and the tin liquor temperature homogeneity is good, helps improving and improving glass quality.
