[0019] 1. The air intake energy-saving equipment for the setting machine, the heat-conducting plate separates the upper and lower gases and conducts heat. The exhaust gas flows inside the exhaust gas heat dissipation space and passes through the through holes on the elastic filter plate. Under normal temperature conditions, the exhaust gas temperature is normal, the heat-conducting plate is in a horizontal state, and the elastic filter plate does not deform.

The higher the heat of the exhaust gas, the greater the force of its thermal expansion gas expansion, which makes the downward concave arc of the heat-conducting plate larger, resulting in a smaller width of the through hole, and then can automatically increase the flow resistance according to the exhaust gas temperature, increase the time that the higher temperature heat source exhaust gas stays in the exhaust gas heat dissipation space, and ensure that the heat of the higher temperature exhaust gas can be fully converted and recovered.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] The embodiment of the present invention provides an air intake energy-saving device for a setting machine, such as Figure 1-7 As shown, it includes an outer sleeve 1, the top of the outer sleeve 1 is fixedly connected to the exhaust gas input pipe 2 and the exhaust gas output pipe 3, the bottom of the outer sleeve 1 is fixedly connected to the air input pipe 4 and the air output pipe 5, and a heat conducting plate 8 is provided in the middle of the inner part of the outer sleeve 1. An exhaust gas heat dissipation space is formed between the upper part of the heat conducting plate 8 and the outer sleeve 1, and an air heating space is formed between the lower part of the heat conducting plate 8 and the outer sleeve 1. The exhaust gas input pipe 2 and the exhaust gas output pipe 3 are connected to the exhaust gas heat dissipation space, and the air input pipe 4 and the air output pipe 5 are connected to the air heating space. An elastic filter plate 9 is provided in the exhaust gas heat dissipation space.

[0031] The elastic filter plate 9 is set to a semicircular shape, the bottom of the elastic filter plate 9 is fixedly connected to the heat conducting plate 8, the top of the elastic filter plate 9 is fixedly connected to the outer sleeve 1, and a through hole 10 is opened on the elastic filter plate 9. The through hole 10 is set to a slender eye shape, and the extension line of the line connecting the two ends of the through hole 10 passes through the center of the circle of the elastic filter plate 9.

[0032] There are multiple through holes 10 , and the multiple through holes 10 are distributed at equal angles with the center of the elastic filter plate 9 as the center.

[0033] The two sides of the outer sleeve 1 are symmetrically fixedly connected with slide grooves 6, and sliders 7 are slidably fitted in the slide grooves 6. The length of the heat conducting plate 8 is greater than the diameter of the outer sleeve 1, and the two ends of the heat conducting plate 8 extend into the slide grooves 6 and are fixedly connected to the sliders 7. A ejection component 11 is provided in the exhaust gas heat dissipation space for concavely pushing the center line of the heat conducting plate 8 downward. When the center line of the heat conducting plate 8 is concave downward, the sliders 7 in the two slide grooves 6 slide inward, and the entire heat conducting plate 8 forms a downward concave arc. The elastic filter plate 9 is deformed so that the center of the elastic filter plate 9 moves downward, so that the distance between the two ends of the through hole 10 on the elastic filter plate 9 becomes longer, resulting in a smaller width of the through hole 10, which increases the difficulty of exhaust gas circulation.

[0034] Two elastic filter plates 9 are provided, and the ejection assembly 11 is provided between the two elastic filter plates 9 .

[0035] The ejection assembly 11 includes an ejection block 18, a vertical rod 16, a piston block 19, an outer tube 15, a connecting rod 12, and a heat conducting plate 17. The top of the connecting rod 12 is fixedly connected to the outer sleeve 1, the bottom end of the connecting rod 12 is fixedly connected to the outer tube 15, the piston in the outer tube 15 is matched with the piston block 19, the bottom of the piston block 19 is fixedly connected to the vertical rod 16, the bottom end of the vertical rod 16 is fixedly connected to the ejection block 18, and the bottom of the ejection block 18 is set to an arc shape, and a gap is formed between the piston block 19 and the outer tube 15. A thermal expansion space is provided, and the thermal expansion space is filled with thermal expansion gas. A heat conducting plate 17 is fixedly connected to the thermal expansion space. Both ends of the heat conducting plate 17 pass through the outer tube 15 and extend to the outside of the outer tube 15. When the exhaust gas temperature in the exhaust gas heat dissipation space is high, the heat is transferred to the thermal expansion space through the heat conducting plate 17. The thermal expansion gas in the thermal expansion space expands and drives the piston block 19 to move downward. The piston block 19 drives the ejection block 18 through the vertical rod 16 to push the middle of the heat conducting plate 8 downward.

[0036] The heat conducting plate 8 separates the upper and lower gases and conducts heat. The exhaust gas flows inside the exhaust gas heat dissipation space and passes through the through hole 10 on the elastic filter plate 9. Under normal temperature conditions, the exhaust gas temperature is normal, the heat conducting plate 8 is in a horizontal state, and the elastic filter plate 9 does not deform. At this time, the width of the through hole 10 is normal, which makes the flow resistance small. When the exhaust gas temperature is high, the thermal expansion gas in the outer cylinder 15 expands due to the heat, causing the thermal expansion gas in the thermal expansion space to expand and drive the piston block 19 downward. The piston block 19 drives the ejection block 18 through the vertical rod 16 to push the middle of the heat conducting plate 8 downward. The heat conducting plate 8 forms a downward concave arc, and the elastic filter plate 9 is deformed so that the center of the elastic filter plate 9 moves downward, so that the distance between the two ends of the through hole 10 on the elastic filter plate 9 becomes longer, resulting in a smaller width of the through hole 10, which increases the difficulty of exhaust gas circulation. The higher the heat of the exhaust gas, the greater the force of its thermal expansion gas expansion, which makes the downward concave arc of the heat conducting plate 8 larger, resulting in a smaller width of the through hole 10, and then the circulation resistance can be automatically increased according to the exhaust gas temperature, thereby increasing the time that the higher temperature heat source exhaust gas stays in the exhaust gas heat dissipation space, ensuring that the heat of the higher temperature exhaust gas can be fully converted and recovered.

[0037] The connecting rod 12 is fixedly connected to a mounting base 13, and the mounting base 13 is rotatably connected to a fan 14. When the exhaust gas flows, the exhaust gas drives the fan 14 to rotate, so that the exhaust gas in the upper part of the exhaust heat dissipation space is driven to the lower part.

[0038] The axis of the mounting base 13 coincides with the axis of the outer cylinder 15 , and the positions of the fan 14 and the heat conducting sheet 17 correspond to each other, so that the airflow driven by the fan 14 can be blown onto the heat conducting sheet 17 .

[0039] By setting the fan 14, when the exhaust gas flows, the exhaust gas drives the fan 14 to rotate, so that the exhaust gas in the upper part of the exhaust gas heat dissipation space is driven to the lower part, ensuring the uniformity of the temperature in the entire exhaust gas heat dissipation space.

[0040] Working principle: The heat-conducting plate 8 separates the upper and lower gases and conducts heat. The exhaust gas flows inside the exhaust gas heat dissipation space and passes through the through hole 10 on the elastic filter plate 9. Under normal temperature conditions, the exhaust gas temperature is normal, the heat-conducting plate 8 is in a horizontal state, and the elastic filter plate 9 does not deform. At this time, the width of the through hole 10 is normal, which makes the flow resistance smaller. When the exhaust gas temperature is high, the thermal expansion gas in the outer cylinder 15 expands due to the heat, causing the thermal expansion gas in the thermal expansion space to expand and drive the piston block 19 to move downward. The piston block 19 drives the ejection block 18 through the vertical rod 16 to push the middle of the heat-conducting plate 8 downward. The heat conducting plate 8 is sunken, and the heat conducting plate 8 forms a downwardly sunken arc. The elastic filter plate 9 is deformed so that the center of the circle of the elastic filter plate 9 moves downward, so that the distance between the two ends of the through hole 10 on the elastic filter plate 9 becomes longer, resulting in a smaller width of the through hole 10, which increases the difficulty of exhaust gas circulation. The higher the heat of the exhaust gas, the greater the force of its thermal expansion gas expansion, which makes the arc of the heat conducting plate 8 concave downward larger, resulting in a smaller width of the through hole 10, and then the flow resistance can be automatically increased according to the exhaust gas temperature, thereby increasing the time that the higher temperature heat source exhaust gas stays in the exhaust gas heat dissipation space, and ensuring that the heat of the higher temperature exhaust gas can be fully converted and recovered.
