Description
The technical field is as follows:
the invention relates to the field of roller way sealing, in particular to a roller way sealing device of a float electronic glass annealing kiln.
Background art:
in the production process of float glass, melting in a kiln, forming in a tin bath and annealing in an annealing kiln are required. The glass ribbon formed by the tin bath is at the temperature of about 600 ℃, enters an annealing kiln through a transition roller table, and is uniformly cooled to about 50 ℃. The glass belt is transmitted through the roller way in the annealing kiln, in order to strictly control a temperature control curve, the entering of external gas is avoided, the gap between the roller way and the sealing cover of the annealing kiln needs to be sealed, the lubricating effect of the roller way is also met, and the common float glass uses high-temperature-resistant lubricating oil at present, so that the lubricating and sealing effects are achieved.
For electronic glass, alumina is usually adopted in a material prescription, the melting point of the alumina is 2054 ℃, the melting temperature of a kiln is increased, the temperature of the glass taken out of a tin bath is higher than that of common glass by more than 100 ℃, the temperature control curve control in an annealing kiln is stricter, and the sealing requirement is higher. If the high-temperature-resistant lubricating oil is adopted, the viscosity of the high-temperature-resistant lubricating oil is easily reduced due to high temperature, the dripping phenomenon occurs, the production line is polluted, and the sealing effect is also reduced. In order to solve the problem, a substance is needed which can not only seal the gap between the roller way and the annealing kiln sealing cover, but also play a role in lubricating the roller way.
The invention content is as follows:
the invention aims to overcome the defects in the prior art and provides a roller way sealing device of a float electronic glass annealing kiln.
The application provides the following technical scheme:
the utility model provides a float process electronic glass annealing kiln roll table sealing device, it includes the axis of rotation and the sealed cowling of annealing kiln roll table, its characterized in that: the shaft body of the rotating shaft between the sealing cover and the rotating shaft is sleeved with a sealing sleeve, the sealing sleeve is provided with a hollow sleeve, one end of the sleeve is communicated with a cooling medium input pipe, and the other end of the sleeve is communicated with a cooling medium output pipe. The sealing cover is made of graphite materials, so that the sealing function can be achieved, the rotating shaft can be lubricated, and friction is reduced.
On the basis of the technical scheme, the following further technical scheme can be provided:
two ends of the sealing sleeve are respectively provided with a section of seal expansion part.
The cooling medium inlet pipe is close to the inner wall of the sealing cover, and the cooling medium outlet pipe is close to the outer wall of the sealing cover.
And a temperature sensor is arranged at one end of the sealing sleeve close to the outer wall of the sealing cover.
The invention has the advantages that:
the invention has the advantages of simple construction, convenient use, capability of cooling the sealing material, avoiding damage caused by long-term work at high temperature, prolonging the service life and the like.
Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
fig. 2 shows the sleeve 4 fitted over the outer wall of the sealing sleeve 3, but not yet welded.
The specific implementation mode is as follows:
as shown in figure 1, the roller way sealing device for the float electronic glass annealing kiln comprises a sealing cover 2, wherein the annealing kiln roller way is arranged in the sealing cover 2, and a rotating shaft 1 of the annealing kiln roller way extends out of the sealing cover 2 to be connected and matched with a power device.
The sealing cover 2 is provided with a through hole corresponding to the rotating shaft 1, a sealing sleeve 3 made of graphite is sleeved on the shaft body of the rotating shaft 1 in the through hole, and two ends of the sealing sleeve 3 are respectively provided with a section of expanding part 3a extending outwards in the radial direction. So that the cross section of the sealing sleeve 3 forms an I-shaped structure. This allows the diameter of the ends of the closure 2 adjacent the inside and outside of the closure 2 to be larger to enhance the sealing effect.
Two I-shaped hollow groove bodies are fastened and welded on the outer wall of the sealing sleeve 3, and the heights of the groove walls on the two sides of each hollow groove body are different, so that an axial opening 4d is reserved on the outer side wall of each sleeve 4 after the hollow I-shaped sleeve 4 is formed on the outer wall of the sealing sleeve 3. So that when two hollow groove bodies are buckled and welded, a welding gun can firstly extend into the groove wall on one side of the hollow groove body which is welded to form the inner wall of the sleeve 4 from the opening 4d, and then the opening 4d is welded and sealed in a repeated welding mode, so that the sleeve 4 is installed in place.
A cooling medium inlet is arranged at one end of the sleeve 4 close to the inner wall of the sealing cover 2, a cooling medium input pipe 4a is communicated with the cooling medium inlet, one end of the cooling medium input pipe 4a extends out of the sealing sleeve 3 to be communicated with a high-pressure cold air source 5, and a solenoid valve 4c which is correspondingly matched with the cooling medium input pipe 4a is also arranged on the outer side of the sealing sleeve 3.
A temperature detector 3b correspondingly matched with the sealing sleeve 3 is arranged on the inner wall of the other end part of the sleeve 4, a cooling medium outlet is arranged on the outer wall of the other end part of the sleeve 4, a cooling medium output pipe 4b is communicated with the cooling medium outlet, and the air outlet end of the cooling medium output pipe 4b extends out of the sealing cover 2. The cooling medium input pipe 4a and the cooling medium output pipe 4b are metal pipes.
A control computer 6 is arranged on the outer side of the sealing sleeve 3, and the electromagnetic valve 4c and the temperature detector 3b are in electric signal connection and matching with the control computer 6 through a lead 7.
The control computer 6 is used for receiving signals transmitted by the temperature detector 3b, monitoring the temperature of the sealing sleeve 3, and controlling the opening or closing degree of the electromagnetic valve 4c so as to control the flow of cooling gas entering the sleeve 4 from the high-pressure cold air source 5 through the cooling medium input pipe 4a, and further control the temperature of the sealing sleeve 3.
The arrows in the figure indicate the direction of the cooling wind flow.
