Description
Technical Field
The invention belongs to the technical field of float glass, and relates to a neck water bag on a float glass melting furnace.
Background
In order to meet the production requirement and the technological requirement of temperature gradient in a float furnace, a large water bag is required to be arranged at the neck of the melting furnace, and the large water bag mainly plays roles in reducing the temperature of a cooling part, blocking scum, saving energy, reducing consumption and the like. Under the condition of high-temperature glass liquid, the requirement of large water-package steel materials is required to be less than 15 months for replacement period.
Along with the promotion to float glass's requirement for quality, big water drum of card neck scum clearance frequency increases, the loaded down with trivial details dismouting process of current card neck water drum is very big extravagant human cost, the installation process both sides are apart from the high temperature environment location difficulty in the brick material after big water drum clearance, big water drum both sides are apart from the refractory material inside distance if not equal, both sides glass liquid velocity of flow has the difference, both sides pool wall damage degree takes place very big change, especially three kinds of material crossing department near the liquid level, the inhomogeneous problem of corroding causes great hidden danger to pool wall safety.
Disclosure of Invention
The invention aims to provide a neck water bag on a float glass melting furnace aiming at the problems in the prior art, and the technical problem to be solved by the invention is how to prolong the maintenance period of the neck water bag.
The purpose of the invention can be realized by the following technical scheme: a neck water drum on a float glass melting furnace is characterized by comprising a body, a connecting arm and a scum collecting cover, wherein the upper end of the body is connected with the connecting arm through a contraction part positioned in the middle of the body, two sides of the contraction part are respectively provided with a U-shaped slow flow liquid through port, the scum collecting cover is positioned at the rear of the body and comprises a bottom plate positioned below the liquid level of the melting furnace, a baffle plate extending out of the liquid level of the melting furnace, a scum removing wheel rotatably connected to the scum collecting cover and a scraper sliding on the bottom plate, the scum removing wheel is provided with a spiral convex rib, the scraper is positioned at the rear of the scum removing wheel, a push block is arranged in front of the scum removing wheel and fixedly connected with the scraper, a guide rail parallel to the axis of the scum removing wheel is arranged on the bottom plate, a guide groove matched with the guide rail is arranged on the push block, the push block can move on the guide rail and push the scum removing wheel to rotate under the guiding action of the convex rib, the deslagging wheel part is positioned above the liquid level of the melting furnace.
Furthermore, the both ends of cover are collected to the dross have one respectively and can arrive the supporting part that leans on at the melting furnace lateral wall top, the fixed mounting bracket that is provided with in melting furnace top, the dross is collected the cover top and has a screw rod of rotating the connection on the mounting bracket, threaded connection has a sliding sleeve on the screw rod, the fixed inserted bar that is provided with on the sliding sleeve, the fixed sleeve pipe that is provided with on the scraper blade, inserted bar sliding connection is intraductal at the sleeve.
Furthermore, one end of the screw is connected with a speed reducing motor.
Furthermore, a coaming parallel to the baffle plate at the supporting part is fixedly arranged on the bottom plate at the supporting part, and a slag discharging groove is formed at the supporting part by the coaming and the side plate.
Furthermore, a return spring is connected between the inserted bar and the sleeve. The return spring can ensure that the scraper is in a pressing state.
The scum is collected the cover and is located slow flow liquid through mouth rear, but does not shelter from slow flow liquid through mouth, only lies in the first half of slow flow liquid through mouth, does not influence the liquid stream and has great circulation cross-section at this position, and can effectively collect the scum.
The arrangement of the slow flow liquid opening can increase the liquid flow cross section above the body on one hand, so that the strength of liquid at the position of a liquid level impacting the side wall of the melting furnace is greatly reduced, the corrosion of the liquid flow in the liquid level area to the side wall of the melting furnace is relieved, the condition that the corrosion degree of the side wall of the melting furnace is different due to unequal intervals between the two sides of the body and the two wall surfaces of the melting furnace is relieved, and the requirement of the installation precision of the body in the melting furnace is reduced; on the other hand, the scum on the liquid surface can enter the position near the scum removing wheel through the slow flow liquid passing port, so that the scum can enter a scum collecting cover formed by the bottom plate and the baffle plate by the rotation of the scum removing wheel.
Receive the effect of glass liquid circulation direction, the dross can be by the place ahead propelling movement to the rear of slagging-off wheel of protruding muscle by the slagging-off wheel under the rotation of slagging-off wheel, propelling movement is to on the bottom plate at slagging-off wheel rear promptly, and the dross that gets into the slagging-off wheel rear receives liquid stream impact force effect and tends to near the baffle, be difficult to send again to slagging-off wheel the place ahead by protruding muscle promptly, at the translation in-process of scraper blade, the dross is pushed to the both ends that the cover was collected to the dross, can discharge outside the dross is collected the cover through the slag notch.
The speed reducing motor drives the screw to intermittently rotate forward and backward, so that the scraper can reciprocate above the bottom plate, and scum collected in the scum collecting cover can be removed in real time.
The scum in the scum collecting cover can be prevented from being impacted by liquid flow, so that the collected scum can not flow on the liquid surface along with the liquid flow, on the other hand, the scum on the liquid flow surface is limited by the convex ribs on the scum removing wheel, the scum before entering the collecting cover can not easily flow away along with the liquid flow from the scum flowing liquid port, and the storage amount of the scum in glass liquid behind the neck clamping water bag is reduced.
Through setting up initiative, real-time slagging-off structure, can prolong the cycle of the dismouting clearance of card neck water drum greatly, also the effectual production pause condition of avoiding causing because of the neutral period of card neck water drum dismouting.
