Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to an electric drying furnace special for photovoltaic glass lip bricks. Background Art

[0002] The photovoltaic glass lip brick is one of the key components in the production of photovoltaic glass. During the cold processing of the lip brick, due to the water cooling of the cutting saw blade and the surface grinder, a certain amount of water infiltrates into the lip brick, and some water penetrates deep into the interior of the lip brick through the newly cut and ground surface, making it difficult to completely dry the lip brick. If this part of the water is not drained before use, when the lip brick is impacted by high-temperature glass liquid, the probability of fracture is high. Even if the lip brick does not break, after the lead head is introduced, the process of continuously discharging water vapor from the lip brick will greatly extend the bubble discharging time of the lip brick and increase the loss of brick replacement. Currently, most photovoltaic glass factories remove moisture from the lip bricks by baking them beside the tank furnace. This method takes a long time, and some even bake for more than one month. When the lip brick needs to be replaced urgently, the drying time is significantly insufficient. Moreover, the temperature beside the tank furnace is also relatively low, and the moisture deep inside the lip brick cannot be completely baked dry.

[0003] Chinese invention with application number CN202310425429.4 discloses a silicon wafer drying device and drying method for making solar photovoltaic glass. The utility model is a silicon wafer drying device for making solar photovoltaic glass, which fully considers the internal air pressure change. Heat source ventilation openings are dispersedly designed inside to allow air to flow downward from the top through the drying area. Using the principle of high-pressure environment converting to low-pressure, when the air reaches the bottom, it squeezes and rises around, increasing air circulation on the basis of drying, and accelerating the drying speed and quality.

[0004] However, in this technical solution, hot air is continuously introduced to dry downward through the heat source ventilation openings, and the air squeezes and rises at the bottom. But such a process requires continuous introduction of hot air to proceed, resulting in high energy consumption. Moreover, the gas discharged from the equipment during this process still carries a large amount of heat energy, causing heat loss. Summary of the Invention

By setting a circulating air component, the circulating flow of gas is agitated inside the furnace body to ensure temperature uniformity.

[0006] After entering the heat preservation stage, the temperature inside the furnace body is maintained. After the heat preservation ends, the power is cut off and the temperature naturally drops to room temperature. The circulating air component continues to agitate the circulating flow of gas to dry the lip brick, solving the problems of long drying time and high energy consumption.

[0032] As Figures 1 to 5 shown, this embodiment provides a special electrothermal drying furnace for photovoltaic glass lip bricks, including a furnace body 1, and is characterized in that it further includes: a track 2 is penetrated through the bottom of the furnace body 1; a furnace car 3 is arranged on the track 2; a circulating air component 4 is arranged on the furnace body 1, and the circulating air component 4 agitates the air flow in the inner cavity of the furnace body 1 to circulate; a temperature control component 5 is further arranged in the two side walls of the furnace body 1, and the temperature control component 5 heats the air flow in the inner cavity of the furnace body 1 and detects the temperature in the inner cavity of the furnace body 1.

[0033] It is worth mentioning here that by setting the track 2 and the furnace car 3, the lip bricks to be dried are placed on the furnace car 3, and then the furnace car 3 is pushed into the furnace body 1 for drying, avoiding the need for manual entry into the high-temperature furnace body 1 to pick up and place the lip bricks, and increasing the safety of manual work.

[0034] A furnace door 11 is rotatably arranged at the front end of the furnace body 1, a lock head 12 is installed on the furnace door 11, and a lock catch 13 is fixedly installed on the furnace body 1, and the lock catch 13 is located on one side of the lock head 12.

[0035] It is worth mentioning here that setting the lock 12 to cooperate with the lock catch 13 to control the opening and closing of the furnace door 11 is simple and convenient.

[0036] A number of cushion blocks 21 are arranged at the bottom of the track 2.

[0037] It is worth mentioning here that by setting the cushion blocks 21 to support the bottom of the track 2 and keep the track 2 horizontal, it is possible to avoid the inclination of the track 2 from increasing the resistance to the pushing of the furnace car 3.

[0038] A number of groups of track wheels 31 are arranged at the bottom of the furnace car 3.

[0039] It is worth mentioning here that the track wheels 31 are set to limit the movement of the furnace car 3 to prevent the furnace car 3 from deviating out of the track 2 during the movement process.

[0040] The length of the inner cavity of the furnace body 1 is L1, the length of the track 2 is L2, and the length of the furnace car 3 is L3. There is a relationship of L2 > L1 + L3 among the three.

[0042] Embodiment 2

[0043] As Figure 2 、 4 、Figure 5 shows, where the same or corresponding components as those in Embodiment 1 adopt the corresponding reference numerals in Embodiment 1.

[0044] It should be noted here that the air duct 41 is not communicated with the outside. When the fan 422 works in the air duct 41, the generated air vortex will not exchange heat with the outside, nor will it introduce external air flow into the furnace body 1 to increase the air pressure.

[0045] It is worth mentioning here that by setting the fan 422 in the top air duct 41 and blowing the cyclone from the bottom of the two side air ducts 41, while agitating the circulating flow of the gas in the furnace body 1, it is avoided that the cyclone generated by the fan 422 directly acts on the lip brick, causing damage and defects to the lip brick, and improving the product quality of the lip brick; multiple groups of fans 42 are set to agitate the air flow in multiple areas of the furnace body 1, so that the temperature in the furnace is more evenly distributed.

[0048] It should be noted here that the heating element 51 is set in the air duct 41 to heat the air in the air duct 41, and then the heated air circulates and flows into the inner cavity of the furnace body 1; a protective cover 511 is arranged outside the circuit connected to the heating element to protect the circuit.

[0049] It is worth mentioning here that the temperature measuring element 52 can timely detect the temperature in the furnace body 1 in real time, keep the temperature constant after confirming that a certain temperature is reached, and then cut off the power supply and let it cool naturally to room temperature. In this process, the moisture in the deep layer of the lip brick is completely removed, saving energy, and it can also be timely feedback through the temperature measuring element 52 when a fault occurs.

[0050] Embodiment IV

[0051] As Figure 1 、 6 shown, an exhaust hole 6 is further arranged at the top of the furnace body 1, and the exhaust hole 6 is connected with a control rod 61 for controlling the opening size of the exhaust hole 6.

[0052] The control rod 61 includes a grip 611, a connecting rod 612 and a flap 613;

[0053] The lower end of the grip 611 is rotatably connected to the rear end of the furnace body 1; one end of the connecting rod 612 is rotatably connected to the top of the grip 611, and the connecting rod 612 penetrates through the exhaust hole 6; the flap 613 is arranged at the other end of the connecting rod 612, and the flap 613 is fixedly connected to the connecting rod 612.

[0054] The flap 613 is arranged in a shape imitating the opening of the exhaust hole 6.

[0056] Working steps

[0057] The worker places the lip bricks to be dried on the furnace cart 3, pushes the furnace cart 3 into the furnace body 1, closes the furnace door 11, turns on the temperature control component 5 and the circulating air component 4. The heating element 52 heats the air in the air duct 41. Under the rotation of the fan 422, a cyclone is generated to promote the circulating flow of the air into the inner cavity of the furnace body 1. After heating to a certain temperature, according to the data detected by the temperature measuring element 52, the output power of the heating element 52 is adjusted, and heat preservation is carried out for a period of time. After the heat preservation ends, the power is cut off and the temperature drops naturally to room temperature. The furnace door 11 is opened, the furnace cart 3 is pulled out, the dried lip bricks are taken out, and another batch of lip bricks is placed for drying.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
