Abstract
The utility model discloses a hot-air drying device for the inner wall of adip-coated glass tube. The device comprises an annular heating device, a hot-air pipe, a hot-air pipe nozzle, a warm-air generator and an air supply pipe, wherein the annular heating device is located above a coating tank; the hot-air pipe nozzle is arranged at an air outlet of the hot-air pipe, an air inlet of the hot-air pipe is connected with the air supply pipe, and the air supply pipe is connected with the warm-air generator; the hot-air pipe is fixed at the bottom of the coating tank and partiallyextends out of a sol liquid level in the coating tank; the hot-air pipe nozzle is located in the center below the section of the glass tube and located between the sol liquid level and the lower bottom surface of the glass tube. The device is simple in equipment and low in cost, the film forming speed can be increased, and the effect caused by the gravityas well as the external environment temperature and humidity on sol film forming is weakened greatly, and thicknesses and colors of formed films are more uniform.
Description
Technical field
The utility model relates to a kind of Glass tubing inwall hot-air drying unit, and particularly one lifts coated glass inside pipe wall hot-air drying unit.
Background technology
In photovoltaic, photo-thermal, photoelectricity industry, a lot of glass components need to carry out coating film treatment, to increase the light transmission of glass, thereby improve sun power utilising efficiency.At present glass surface plated film is mainly adopted to sol-gel coating method, its ultimate principle is using metal alkoxide or inorganic salt as presoma, be dissolved in the uniform solution of formation in solvent (water or organic solvent), solute and solvent produce hydrolysis or alcoholysis reaction, resultant of reaction is assembled to be become nanometer particle and forms colloidal sol, by spin coating plating method or lift plating method collosol and gel and drying treatment are obtained to xerogel film, last sintering heat at a certain temperature obtain required crystalline state or noncrystalline membrane.
In actual production, lifting plating method is a kind of method that is widely used in the film preparation of scientific research aspect, can on silicon chip or cylindrical substrate, plate uniform film.Lift the relative spin coating filming equipment of plated film simple, cost is low, and membrane component is easy to control, be easy to adulterate, and can while two sides plated film.But, adopting and lift film coating method in the time that large-area coating film is produced, thickness and color are difficult to uniformity, and there will be obvious aberration between each batch, keep the colour consistency between color homogeneity and each sheet glass more difficult.Major cause is that in film process, colloidal sol does not have timely drying and forming-film, under action of gravity, piles up and causes film forming thickness inhomogeneous, is subject to the variable effect of environment temperature and humidity larger in plated film film process simultaneously.
Chinese patent CN202877032U discloses a kind of large-scale film coating apparatus that lifts, this patent is provided with drying unit above plated film pond, but this device is made up of the adjustable carbon fiber heating tube of Heating temperature, only can dry Glass tubing outer wall, can not realize Glass tubing inwall is effectively dried, make film forming thickness still inhomogeneous.
Utility model content
The purpose of this utility model is to provide one and lifts coated glass inside pipe wall hot-air drying unit, to be controlled to film thickness and color.
To achieve these goals, the technical solution of employing is the utility model: one lifts coated glass inside pipe wall hot-air drying unit, comprises ring shaped heating mechanism, heating duct, heating duct nozzle, warm braw producer, blast tube; Described ring shaped heating mechanism is positioned at top, plated film pond; The air outlet of described heating duct is provided with heating duct nozzle, and the blast inlet of described heating duct connects blast tube, and described blast tube connects warm braw producer; Described heating duct is fixed on bottom, plated film pond and stretches out a colloidal sol liquid level part in plated film pond; Described heating duct nozzle is positioned at the central position of below, Glass tubing cross section, and between melten gel liquid level and Glass tubing bottom surface.
Further, described warm braw producer is connected with temperature regulator.
Further, the blast inlet of described warm braw producer is provided with high efficiency particle air filter.
Further, described ring shaped heating mechanism comprises circular heating tube, and described circular heating tube is arranged on the top in plated film pond.
Further, described circular heating tube is the adjustable carbon fiber heating tube of Heating temperature.
The beneficial effect that the utility model can produce: Glass tubing outer wall is carried out to prebake by adopting, inwall is carried out to the method for hot-air seasoning, when Glass tubing lifts plated film, carry out drying treatment, can accelerate film forming speed, greatly weaken the impact on colloidal sol film forming of gravity and ambient temperature and wetness action, make film forming thickness and color more even, lift plated film and dry and in succession finish complete time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, Glass tubing 2, ring shaped heating mechanism 3, heating duct 4, plated film pond 5, heating duct nozzle 6, colloidal sol liquid level 7, temperature regulator 8, warm braw producer 9, high efficiency particle air filter 10, blast tube.
Embodiment
Below in conjunction with Fig. 1, the utility model is elaborated.
A kind of drying unit that lifts plated film for Glass tubing is provided as shown in Figure 1, be arranged on and lift on film coating apparatus, wherein ring shaped heating mechanism 2 is arranged on 4 tops, plated film pond that lift film coating apparatus, lifting Glass tubing 1 with pulling apparatus at the uniform velocity moves upward, realize Glass tubing 1 outside surface homogeneous heating, by the moisture evaporate to dryness in colloidal sol; Heating duct 3 is arranged on 4 bottoms, plated film pond, and the heating duct air outlet of upper end stretches out colloidal sol liquid level 6 parts in plated film pond 4, and heating duct nozzle 5 is arranged on the air outlet of heating duct 3, between melten gel liquid level 6 and Glass tubing 1 bottom surface; Heating duct nozzle 5 is positioned at Glass tubing 1 kernel of section position, lift Glass tubing 1 with pulling apparatus, when Glass tubing 1 leaves colloidal sol liquid level 6 and moves up, heating duct nozzle 5 is sprayed at warm air Glass tubing 1 inwall uniformly with wind speed and the temperature set, realizes Glass tubing 1 inwall circular hot air and dries; Heating duct 3 inlet mouths are provided with the warm braw producer 8 of controlling air output and the temperature regulator 7 of setting warm braw temperature, and extraneous air is sent uncontaminated air into heating duct 3 by high efficiency particle air filter 9 and blast tube 10, avoids impurity in film process to enter film.Pull rate, air output and warm braw temperature can be set, three factor co-controlling film forming thickness and quality.Lifting plated film dries and in succession finishes complete time.
