Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air duct production, in particular to an air duct device for special purposes. Background Art
[0002] Air duct is a piping system used for air transportation and distribution. There are two types: composite air duct and inorganic air duct. Composite air duct is represented by air duct and can be classified according to cross-sectional shape and material. The production of stainless steel air duct is to apply sealant (such as neutral glass glue) on the bite seam, rivet seam, flange corners and other gaps. Before applying sealant, the surface dust and oil should be removed. According to the cross-sectional shape, the air duct can be divided into circular air duct, rectangular air duct, oblate air duct and other types. Among them, the circular air duct has the smallest resistance but the largest height dimension and is complex to produce, so the application is mainly rectangular air duct. According to the material, the air duct can be divided into metal air duct, composite air duct and polymer air duct.
[0003] Chinese patent application number CN201120277440.3 discloses a novel fixing structure for an electric heating device for a duct machine and a duct machine. Its advantages and positive effects are as follows: 1. The electric heating components are fixed to a support frame and then fixedly mounted as a whole on the air outlet flange of the duct machine. The electric heating device can be installed on site, and users can choose according to their actual needs. 2. The electric heating component wires are connected to components in an electric control box used for electric heating alone. A separate power line is drawn from the electric control box to power the electric heating device, thereby not affecting the current of the entire machine. The terminal board and internal and external unit communication lines on the entire machine will not cause safety hazards due to excessive current. 3. The support frame is a sheet metal part, which eliminates safety hazards such as heating and ignition of the insulation cotton inside the duct machine.
[0004] However, when currently producing flexible glass and substrate glass using the downdraw method, the products are cut and separated from the effective area in the middle of a continuous ribbon of glass. In order to control the thickness accuracy of this effective area, an independent cooling mechanism is set up. At the same time, in order to widen the width of this effective area, an independent heating device is set up. At the same time, both cannot be installed and used at the same location, resulting in a decrease in overall work efficiency. To this end, we have proposed a special-purpose air duct device.

One end of the inner insulating exhaust ceramic tube 2 is flat and expanded outward, and an exhaust port 5 is provided. A connecting groove 6 is provided on the end of the outer insulating ceramic tube 3 away from the exhaust port 5; and a joint component 7 is also included. The joint component 7 is arranged on the inner insulating exhaust ceramic tube 2 and fixedly connected thereto. It includes an air intake connector 8 arranged on the inner insulating exhaust ceramic tube 2 and away from one end of the exhaust port 5, the air intake connector 8 is fixedly connected to the inner insulating exhaust ceramic tube 2, and an air intake port 9 is opened on the air intake connector 8; a thermocouple assembly 10, the thermocouple assembly 10 is arranged on the air intake connector 8, which includes a thermocouple block 11 arranged on the air intake connector 8 and away from one end of the inner insulating exhaust ceramic tube 2, wherein the width range of the exhaust port 5 is between 1 mm and 2 mm. In addition, the thermocouple block 11 is a standard thermocouple and is adapted to the air intake connector 8.
[0036] In an embodiment of the present application, the temperature control component 1 includes an independent heating element 12 arranged in the outer insulating ceramic tube 3 and sleeved on the outside of the inner insulating exhaust ceramic tube 2. The independent heating element 12 does not contact the inner insulating exhaust ceramic tube 2 and the outer insulating ceramic tube 3. In addition, the independent heating element 12 is isolated from the outside air after installation.
[0037] In some embodiments, an electrode connector 13 is provided at the end of the independent heating element 12, and the electrode connector 13 is located outside the outer insulating ceramic tube 3 through a connecting groove. An insulating filling material 14 is provided between the inner insulating exhaust ceramic tube 2 and the outer insulating ceramic tube 3, wherein the flat mouth of the exhaust port 5 is oriented at an angle of 45 degrees to the electrode connector 13.

When the narrow slit of the exhaust port 5 is placed horizontally, the control area is the widest, and when it is placed vertically, the control area is the narrowest. When the control range needs to be adjusted, it can be achieved by rotating it around its own axis as the main axis and adjusting the angle between the narrow slit of the exhaust port 5 and the horizontal plane.

In this state, a stable monitoring temperature is obtained, which is defined as the reference benchmark balance point. If the working medium flow and the heating element power are adjusted above the reference benchmark balance point, the glass in the corresponding area will be thinner; if the working medium flow and the heating element power are adjusted below the reference benchmark balance point, the glass in the corresponding area will be thicker.
[0042] It should be noted that it has the characteristics of stable state, sensitive adjustment, and continuously adjustable thickness. When used in the down-draw method to produce flexible glass or substrate glass, it can maximize the utilization of equipment capacity and improve equipment efficiency while improving glass quality. At the same time, the device can also be expanded to equipment with this functional requirement.
