[0006] However, the structure of the above-mentioned silver paste temperature recovery device is relatively complex, and the time for the silver paste to recover temperature is still relatively long. Summary of the invention

[0007] In view of the problems existing in the prior art, the present invention provides a silver paste temperature recovery device for laying silver paste wires for electrochromic applications and its application. The silver paste storage device is arranged on an inclined rotating shaft, the rotating shaft drives the silver paste storage device to rotate, and the silver paste storage device is in full contact with dry hot air for heat exchange, thereby achieving efficient and rapid temperature recovery of the silver paste.

[0008] To achieve this object, the present invention adopts the following technical solutions:

[0009] In a first aspect, the present invention provides a silver paste temperature recovery device for laying silver paste wires for electrochromic applications, the silver paste temperature recovery device for laying silver paste wires for electrochromic applications comprises a silver paste storage device, a rotating shaft, an impeller, a gas channel and a bracket;

[0010] The rotating shaft is tiltedly arranged on the bracket; the silver paste storage device is arranged on the rotating shaft and in the gas channel; and the impeller is arranged at the inlet end of the gas channel.

[0011] The silver paste reheating device for laying silver paste wires for electrochromic use of the present invention is provided with a rotating shaft, which drives the silver paste storage device to rotate, thereby avoiding precipitation and separation of the silver paste during the reheating process; dry hot air is introduced into the gas channel, which can both heat the silver paste and prevent water vapor condensation from appearing on the outer wall of the silver paste storage device. The silver paste reheating device for laying silver paste wires for electrochromic use of the present invention is easy to use, can realize silver paste reheating without standing for too long, has high processing efficiency and good quality of the silver paste after reheating.

[0012] Preferably, the inclination angle of the rotating shaft is 20° to 50°, for example, it can be 20°, 22°, 25°, 30°, 40°, 45° or 50°, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0013] The preferred inclination angle of the rotating shaft of the present invention is 20° to 50°, so that the compressed air and the silver paste storage device can be in contact with each other over a large area and fully exchange heat. If the rotating shaft is set horizontally, the compressed air passes through the silver paste storage device quickly, and the heat exchange efficiency with the silver paste is reduced, resulting in a longer time for the silver paste to return to temperature.

[0014] Preferably, the rotating shaft is connected to a generator.

[0015] Preferably, the material of the silver paste storage device includes stainless steel, which not only has good sealing, corrosion resistance and high temperature resistance, and prevents the silver paste from being contaminated, but also facilitates effective heat exchange between the silver paste and hot air, improves the silver paste warming efficiency, and shortens the silver paste warming time.

[0016] In the second aspect, the present invention also provides an application of the silver paste temperature recovery device for laying silver paste wires for electrochromic change as described in the first aspect, wherein compressed air is introduced into the inlet end of the gas channel of the silver paste temperature recovery device for laying silver paste wires for electrochromic change, and the impeller rotates to increase the kinetic energy of the compressed air; the rotating shaft arranged on the bracket drives the silver paste storage device to rotate, thereby realizing the silver paste temperature recovery for laying silver paste wires for electrochromic change.

[0017] The application of the silver paste warming device for laying the silver paste wire for electrochromic change of the present invention allows compressed air to be introduced into the inlet end of the gas channel, so that the compressed air flows from a lower position on one side of the gas channel to a higher position on the other side, thereby increasing the contact area between the compressed air and the silver paste storage device, prolonging the contact time, and greatly improving the silver paste warming effect. Moreover, the silver paste storage device is driven to rotate by the rotating shaft, so as to avoid the precipitation and separation of the silver paste and ensure the quality of the silver paste.

[0018] Preferably, the pressure of the compressed air is 0.2-0.3 MPa, for example, it can be 0.2 MPa, 0.21 MPa, 0.23 MPa, 0.25 MPa, 0.27 MPa, 0.29 MPa or 0.3 MPa, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0019] Preferably, the pressure dew point of the compressed air is -30 to -10°C, for example, it can be -30°C, -25°C, -20°C, -18°C, -15°C or -10°C, etc., but it is not limited to the listed values. Other unlisted values ​​within this numerical range are also applicable, which can avoid water vapor condensation on the outer wall of the silver paste storage device.

[0020] Preferably, the temperature of the compressed air is 30-40°C, for example, it can be 30°C, 31°C, 32°C, 35°C, 36°C, 38°C or 40°C, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0021] The preferred temperature of the compressed air in the present invention is 30-40°C, so as to achieve low-cost and high-efficiency temperature recovery of the silver paste. When the temperature is high, an additional compressed air heating device is required, which will increase the processing cost of the silver paste temperature recovery; when the temperature is low, the silver paste temperature recovery time will be long, and even lower temperatures will cause the silver paste to be unable to recover.

[0022] Preferably, the rotation speed of the rotating shaft is 30 to 160 r / min, for example, it can be 30 r / min, 50 r / min, 60 r / min, 80 r / min, 100 r / min, 140 r / min or 160 r / min, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0023] The present invention preferably has a rotation speed of 30 to 160 r / min to ensure a good silver paste reheating effect. When the rotation speed of the rotation shaft is too slow, water condenses on the outer wall of the silver paste storage device and the silver paste deposits in agglomerates; when the rotation speed of the rotation shaft is too fast, the silver paste will be centrifugally separated.

[0024] As a preferred technical solution of the present invention, compressed air with a pressure of 0.2 to 0.3 MPa, a pressure dew point of -30 to -10°C, and a temperature of 30 to 40°C is introduced into the inlet end of the gas channel of the silver paste temperature recovery device for laying the electrochromic silver paste wire, and the impeller rotates to increase the kinetic energy of the compressed air; a rotating shaft with a rotation speed of 30 to 160 r / min arranged on the bracket drives the silver paste storage device to rotate, thereby realizing the silver paste temperature recovery for laying the electrochromic silver paste wire.

[0025] Compared with the prior art, the present invention has at least the following beneficial effects:

[0026] The invention provides a silver paste temperature recovery device for laying silver paste wires for electrochromic applications, which has a reasonable design and a simple structure. By using dry hot air to contact and exchange heat with the silver paste, efficient temperature recovery of the silver paste is achieved under the action of a rotating shaft without precipitation and separation. Moreover, there is no water vapor condensation on the outer wall of the silver paste storage device, which will not affect the quality and use of the silver paste. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] This comparative example also provides an application of the above-mentioned silver paste temperature recovery device for laying silver paste wires for electrochromic application, which is the same as Example 2.

[0051] In this comparative example, since the rotating shaft 2 is horizontally arranged on the bracket 5, the compressed air and the silver paste storage device cannot fully exchange heat, the silver paste temperature recovery efficiency is low, and the temperature recovery time is long.
