An outlet 34 for connecting to the air inlet of the return air blower is provided on the second air box 3.

[0032] Compared with the prior art, for the tin bath cooling device for glass production equipment provided by the present utility model, when cooling the bottom of the tin bath 4, the cooling air source enters the first air box 1, enters the air guiding pipe 2 from the air outlet, and finally blows towards the bottom of the tin bath 4 from the cooling port 21 to cool the bottom of the tin bath 4; the gas blown towards the bottom of the tin bath 4 can be sucked into the second air box 3 under the action of the return air blower, so that the air flow can flow horizontally along the tin bath 4, increasing the contact range between the cooling air flow and the bottom of the tin bath 4, and further improving the cooling effect.

[0033] Exemplarily, the air ducts 2 at the top of the first air box 1 are arranged in several rows. In this embodiment, two rows are taken as an example for illustration. Each row of air ducts 2 is provided with several spaced along the length direction of the first air box 1. The top end of each air duct 2 has an external thread, and a cover body 22 is threadedly connected to the threaded end of each air duct 2. In this embodiment, it is taken as an example that the cover body 22 has two cooling openings 21; the two cooling openings 21 on the cover body 22 both face the bottom of the tin bath 4, and the number of cooling openings 21 on the cover body 22 is not limited to two. Through the above settings, the cover body 22 at the end of the air duct 2 can be replaced. When other numbers of cooling openings 21 are required, the cover body 22 with a preset number of cooling openings 21 can be replaced.

[0034] In some embodiments, as Figures 1 to 6 shown, the air duct 2 is provided with an atomizing nozzle 5 at the position of each cooling opening 21, and the atomizing nozzle 5 faces the bottom of the tin bath 4; the atomizing nozzle 5 is connected to a water source through a pipeline, and a water pump (not shown in the figure) is provided on the pipeline; wherein, under the action of the water pump, the atomizing nozzle 5 can spray water mist towards the bottom of the tin bath 4 so that the water mist exchanges heat with the bottom of the tin bath 4. A water box 51 is sleeved at the position of the cooling opening 21 of the air duct 2. One end of the atomizing nozzle 5 is communicated with the water box 51, and the other end faces the tin bath 4; a joint 52 is connected to the water box 51, and the joint 52 can be communicated with the pipeline, so that the water box 51 is connected to the water pump.

[0035] It should be noted that a water pool (not shown in the figure) can be arranged on one side of the first air box 1, and the water in the water pool is the water source; under the drive of the water pump, the water in the water pool can be pumped into the atomizing nozzle 5, and then the atomizing nozzle 5 sprays the water onto the bottom of the tin bath 4 in an atomized manner; the atomized water sprayed onto the bottom of the tin bath 4 can exchange heat with the bottom of the tin bath 4, and the atomized water can absorb heat and turn into steam, and enter the second air box 3 together with the air flow. By spraying atomized water onto the bottom of the tin bath 4, the cooling effect can be further improved, and the bottom of the tin bath 4 can be maintained within a preset temperature range.

[0036] Exemplarily, several temperature sensors can be arranged at the bottom of the tin bath 4, and the temperature sensors can monitor the temperature at the bottom of the tin bath 4. When the air flow cooling method can maintain the bottom of the tin bath 4 within a preset temperature range, the water pump does not need to be started, that is, at this time, it is not necessary to spray atomized water onto the bottom of the tin bath 4; when the air flow cooling method cannot reduce the bottom of the tin bath 4 to the preset range, the water pump is started at this time. By contacting the atomized water with the bottom of the tin bath 4, the temperature at the bottom of the tin bath 4 can be further reduced so that the temperature at the bottom of the tin bath 4 is maintained within the preset range.

[0037] In some embodiments, as Figures 1 to 6As shown, the interior of the second bellows 3 has a number of first baffles 32 and a number of second baffles 33; the number of first baffles 32 are spaced on one side inside the second bellows 3, and the number of second baffles 33 are spaced on the other side inside the second bellows 3; wherein, the first baffles 32 and the second baffles 33 are arranged alternately so as to form a meandering air duct inside the second bellows 3; the first baffles 32 and the second baffles 33 are used to condense water vapor, and the second bellows 3 is provided with a drainage structure.

[0038] Exemplarily, the air flow entering the second bellows 3 carries water vapor. When the water vapor contacts the inner side wall of the second bellows 3, the first baffles 32 and the second baffles 33, the water vapor can condense into liquid water and finally gather at the bottom of the second bellows 3, enabling the recycling of water resources and reducing the waste of water resources.

[0039] In some embodiments, as Figures 1 to 6 shown, the drainage structure includes a valve provided at the bottom of the second bellows 3 or at a position near the bottom on the side of the second bellows 3. The valve is connected to a water source through a pipeline, and the height of the water source is lower than the height of the valve.

[0040] It should be noted that when the liquid level inside the second bellows 3 is lower than the preset liquid level, the valve is in a closed state; when the liquid level inside the second bellows 3 is higher than the preset liquid level, the valve is opened at this time, so that the water inside the second bellows 3 flows into the pool through the pipeline.

[0041] In some embodiments, as Figures 1 to 6 shown, enclosures 11 are provided around the top of the first bellows 1. The enclosures 11 and the top of the first bellows 1 form a condensed water storage area, and the enclosures 11 are provided with a drainage structure; the drainage structure includes a valve provided on the enclosures 11. The valve is connected to a water source through a pipeline, and the height of the water source is lower than the height of the valve.

[0042] It should be noted that when the water vapor condenses on the air guide pipe 2 or the second bellows 3, the condensed water will flow downward to the top of the first bellows 1; by providing the enclosures 11 on the top of the first bellows 1, the condensed water on the top of the first bellows 1 can be limited and collected; when the water level of the condensed water on the top of the first bellows 1 is higher than the preset height, the valve is opened, so that the condensed water on the top of the first bellows 1 flows into the pool through the pipeline; through the above settings, water resources can be saved.

[0043] Exemplarily, the valve on the enclosures 11 can also be in an open state all the time, enabling the condensed water on the first bellows 1 to be discharged in time.

[0044] In some embodiments, as Figures 1 to 6As shown, a number of cooling induced draft fans (not shown in the figure) are provided at intervals on the first bellows 1, and the air outlets of each cooling induced draft fan are communicated with the inside of the first bellows 1; a cooling box body is connected to the air inlet of the cooling induced draft fan, the top of the cooling box body has an opening, a filter screen is provided in the cooling box body, and a number of ice cubes for cooling the air flow are provided on the filter screen. The first bellows 1 is provided with a connecting pipe 12 connected to the air outlet of the cooling induced draft fan.

[0045] It should be noted that the cooling induced draft fan can blow air flow into the first bellows 1, and finally make the air flow blow from the cooling port 21 to the bottom of the tin bath 4; by arranging the cooling box body 13 at the air inlet of the cooling induced draft fan and arranging the filter screen 14 in the cooling box body 13, the ice cubes on the filter screen 14 can play a role in cooling the air flow, so that the temperature of the air flow blown into the first bellows 1 by the cooling induced draft fan is reduced.

[0046] Exemplarily, the ice cubes on the filter screen 14 are crushed ice cubes, and the crushed ice cubes are arranged at intervals on the filter screen 14, so that the gas can pass through the filter screen 14, and the crushed ice cubes can play a role in cooling the gas.

[0047] Exemplarily, the cooling box body 13 is provided with a water guide pipe 15, the water guide pipe 15 is communicated with a water source, the height of the water source is lower than the height of the cooling box body 13, and a valve is provided on the water guide pipe 15. The water generated after the ice cubes melt will fall into the inside of the cooling box body 13. By opening the valve on the water guide pipe 15, the water in the cooling box body 13 can flow into the water pool. The cooling box body 13 is provided with an interface communicated with the cooling induced draft fan.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
