Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a humidity management device and a temperature and humidity management device. Background Technique

[0002] The influence of humidity on glass in the hot cutting area of domestic new display material carrier plates and substrate glass production lines: 1. Changes in mechanical properties: It may lead to a decrease in glass strength, affecting the hardness, toughness, and impact resistance of the glass. 2. Changes in thermal properties: It may cause changes in the thermal conductivity coefficient, resulting in changes in heat conduction, affecting the thermal stability of the glass, and causing the glass to break or deform. 3. Changes in optical properties: It affects the refractive index, light transmittance, dispersion, and light absorption of the glass. The existing technology cannot meet the process production requirements for the humidity control accuracy in the hot cutting area, and the fluctuation range of the humidity value is relatively large, affecting the glass quality and resulting in quality fluctuations. In order to produce glass products that meet the process requirements and are of qualified quality, and improve production efficiency and glass quality, the environmental humidity in the hot cutting area should be efficiently controlled, the control accuracy should be improved, and it should be stabilized within the effective value range.

[0003] Most existing humidifying devices spray water vapor in the target area. During this process, condensation of water vapor is inevitable. On the one hand, the water vapor is brought into the designated area by a centrifugal fan. Over time, the condensed condensate water is likely to cause the centrifugal fan to rust, reducing the service life of the centrifugal fan. At the same time, in the hot cutting area, the cleanliness requirement is high, and the cleanliness is 1000 grade. Once the fan shows signs of rust, it will reduce the cleanliness of the hot cutting area and cause poor glass quality. On the other hand, it will cause tiny water droplets to appear on the glass surface. Over time, these water droplets will cause the glass to mildew and affect the product quality.

[0004] Therefore, there is an urgent need to design a humidity management device and a temperature and humidity management device to solve the above problems. Summary of the Utility Model

[0034] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", and "right" are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0035] This embodiment provides a humidity management device, which can avoid the water vapor ejected from the spray pipe 11 containing condensed water, extend the service life of the fan 12, and ensure the quality of the cut products. As Figure 1 and Figure 2As shown, the humidity management device includes a humidifying component 10 and an anti-condensation pipeline 20. The humidifying component 10 includes a nozzle 11 and a fan 12 (also known as a centrifugal fan). A plurality of nozzle holes 111 are provided on the nozzle 11. The fan 12 is located on one side of the nozzle 11. Water vapor can be sprayed out from the plurality of nozzle holes 111 and carried to the hot-cutting area 500 by the wind force of the fan 12; water vapor enters from the inlet 21 of the anti-condensation pipeline 20 and is sprayed out from the plurality of nozzle holes 111. At least part of the anti-condensation pipeline 20 is arranged to fit the outer wall of the nozzle 11.

[0036] The above-mentioned humidity management device is provided with an anti-condensation pipeline 20, and at least a part of the anti-condensation pipeline 20 is arranged to fit the outer wall of the nozzle 11, so that when water vapor passes through the anti-condensation pipeline 20, the nozzle 11 is first preheated, so that the temperature of the nozzle 11 is consistent with the temperature of the water vapor, avoiding the condensation of water vapor at the nozzle 11 due to the low temperature of the nozzle 11, thereby reducing the content of condensed water in the water vapor ejected from the nozzle hole 111, and thus preventing the condensed water from entering the fan 12, preventing the fan 12 from rusting, extending the life of the fan 12, or being carried to the hot cutting area 500 by the fan 12, preventing the glass from contacting with condensed water and rust, thereby improving the quality of the finished glass product.

[0037] Alternatively, as Figure 2 As shown, the portion of the anti-condensation pipe 20 attached to the outer wall of the nozzle 11 serves as a preheating pipe 22. The nozzle 11 extends in a predetermined direction, and the plurality of nozzle holes 111 are spaced apart along the predetermined direction. The preheating pipe 22 surrounds at least a portion of the nozzle 11 located on either side of the plurality of nozzle holes 111. It will be appreciated that the preheating pipe 22 is U-shaped and hollow inside, with the two long sides of the U-shaped preheating pipe 22 located on either side of the nozzle 11 to preheat the nozzle 11.

[0038] Alternatively, as Figure 2 As shown, the preheating pipe 22 is groove-shaped and has a double wall. Water vapor is allowed to pass between the double walls. The opening of the groove-shaped preheating pipe 22 is arranged to avoid the multiple nozzles 111. It can be understood that compared with the solution of the preheating pipe 22 being U-shaped, the contact surface between the preheating pipe 22 and the nozzle 11 is larger, and the preheating effect is better. Figure 2 As shown, the preheating pipe 22 has two side walls 221 , and a space between the two side walls 221 is used to allow water vapor to pass through.

[0039] Optionally, the anti-condensation pipeline 20 further includes a steam drum 28, which is located downstream of the preheating pipeline 22 and upstream of the nozzle 11. Through the above arrangement, the steam drum 28 can ensure that the water vapor is homogenized within the larger space of the steam drum 28 before reaching the nozzle 11, ensuring that the water vapor entering the nozzle 11 is uniform.

[0040] In addition, the steam drum 28 can also condense part of the water vapor in the steam drum 28, further reducing the possibility of water vapor condensation in the nozzle 11.

[0041] In an optional embodiment, a valve is provided at the bottom of the steam drum 28. The valve can be opened or closed. In the working state, the valve is in the closed state. After working for a period of time, the valve is opened to discharge the accumulated condensed water to the outside.

[0042] In this embodiment, as Figure 2 shown, the anti-condensation pipeline 20 further includes a condensate pipe 23 and a steam trap 24. The condensate pipe 23 is communicated with the bottom of the steam drum 28, and the other end of the condensate pipe 23 is connected with a steam trap 24. Through the above settings, the water condensed in the steam drum 28 flows out from the condensate pipe 23. The steam trap 24 has the function of blocking steam and draining water, which can block the water vapor back to the condensate pipe 23, prevent the loss of water vapor, and directly discharge the condensed water to the outside without regularly releasing the condensed water, simplifying the operation. Among them, the steam trap 24 is a part in the prior art, and its structure and working principle will not be elaborated here.

[0043] Optionally, as Figure 1 and Figure 2 shown, the steam drum 28 and the nozzle 11 are communicated through a first pipeline 25. A first valve 271 is provided on the first pipeline 25. A humidity sensor 510 is provided in the hot cutting area 500, and the humidity sensor 510 is communicatively connected with the first valve 271. It can be understood that the first valve 271 is an automatic valve. The humidity sensor 510 can monitor the humidity in the hot cutting area 500 at any time. When the humidity is high, the first valve 271 appropriately reduces the passage; when the humidity is low, the first valve 271 appropriately enlarges the passage to ensure that the humidity in the hot cutting area 500 fluctuates within a preset range.

[0044] It should be noted that the communication connection between the humidity sensor 510 and the first valve 271 is a setting in the control field, and its signal transmission is generally carried out through a host computer or a PLC, which will not be elaborated here.

[0045] Among them, the adjustment range of the first valve 271 has certain limitations. Under extreme working conditions, the adjustment range of the first valve 271 cannot meet the working condition requirements.

[0046] To solve the above problems, as Figure 2As shown, the inlet 21 of the anti-condensation line 20 and the preheating line 22 are connected via a second line 26. A second valve 272 is provided on the second line 26. This mechanical valve 272 allows manual flow adjustment of the second valve 272 when the first valve 271 fails to adjust the flow rate, thereby meeting the humidity control requirements under extreme operating conditions in the hot zone 500. The combination of the first valve 271 and the second valve 272 can expand the flow range of water vapor.

[0047] Alternatively, as Figure 2 As shown, the inlet 21 of the anti-condensation pipeline 20 and the preheating pipeline 22 are connected through a second pipeline 26. A pressure gauge 29 is provided on the second pipeline 26 to monitor the pressure of water vapor at any time and issue an early warning to prevent the pressure of water vapor entering from being too high and causing damage to the pipeline.

[0048] This embodiment also provides a temperature and humidity management device, such as Figure 1 As shown, the temperature and humidity management device includes the aforementioned humidity management device and a temperature adjustment assembly 400, which is used to heat or cool the air. The temperature adjustment assembly 400 is located on the side of the nozzle 11 facing away from the fan 12. Through the above arrangement, the temperature and humidity management device can simultaneously achieve temperature and humidity management, meeting the working conditions of glass thermal cutting.

[0049] Alternatively, as Figure 1 As shown, the temperature and humidity management device further includes a medium efficiency filter 200, which is located between the temperature adjustment component 400 and the nozzle 11. Through the above arrangement, the air is filtered and then passes through the fan 12, which ensures the cleanliness of the air without polluting the ejected water vapor.

[0050] Alternatively, as Figure 1 As shown, the temperature and humidity management device also includes a primary filter 300, which is located on the side of the temperature adjustment component 400 away from the medium filter 200. Through the above setting, before the air passes through the temperature adjustment component 400, the primary filter 300 first filters the air to prevent the temperature adjustment component 400 from being contaminated by the air.

[0051] Alternatively, as Figure 1 As shown, the temperature adjustment assembly 400 includes a heating element 410 and a cooling element 420 arranged side by side, and one of the two elements is in operation to achieve heating or cooling of the air.

[0052] Optionally, the heating element 410 and the cooling element 420 are both tubular and are used to pass hot water and cold water. In other embodiments, the heating element 410 and the cooling element 420 can also be powered to achieve heating or cooling, which is not limited here.

[0053] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
