Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0023] See also Figure 1-5The present invention provides a technical solution: an exhaust mechanism of a tempering furnace for glass production, comprising an exhaust mechanism main body 1 and a tempering furnace 8, an exhaust fan 6 is arranged on the exhaust mechanism main body 1, a support box seat 3 is arranged on the exhaust mechanism main body 1, and the support box seat 3 is screwed and fixed to the middle part of the upper end of the tempering furnace 8, a motor 2 and an exhaust fan 6 are also screwed and fixed to the support box seat 3 respectively, this structure enables the motor 2 and the exhaust fan 6 to be firmly installed on the upper end of the tempering furnace 8 through the support box seat 3, and an impeller 602 is installed in the exhaust fan 6, and a motor 2 for rotating the impeller 602 is installed on the side of the exhaust fan 6, an exhaust main pipe 7 is connected to the air inlet end of the exhaust fan 6, and exhaust branch pipes 701 communicating with the inside of the tempering furnace 8 are evenly spaced and connected to the exhaust main pipe 7, and the exhaust An exhaust passage 601 is provided at the outlet end of the fan 6, and a guide baffle 5 is provided on the exhaust mechanism body 1 inside the tempering furnace 8. The guide baffle 5 is an inverted U-shaped structure, and the two sides of the guide baffle 5 are inclined. This structure can guide the exhaust of the gas in the tempering furnace 8 through the guide baffle 5, and exhaust holes 501 are evenly spaced at the upper end of the guide baffle 5, and exhaust guide plates 4 are evenly spaced and connected to the upper end of the guide baffle 5. The exhaust guide plates 4 are inclined toward the same side. This structure guides the airflow through the inclined setting of the exhaust guide plate 4, and increases the contact time between the gas and the exhaust guide plate 4, ensuring the heat exchange efficiency. The exhaust guide plate 4 is relatively vertically arranged with the exhaust hole 501. This structure makes the bottom of the exhaust guide plate 4 and the exhaust hole 501 close to each other. 1 forms a grid structure, so that the flow area of the gas is divided into small areas, the circulation rate is increased, the air flow is evenly distributed, and the temperature in the tempering furnace is ensured to be balanced. A supporting baffle 10 is also provided above the guide baffle 5, and a through hole is provided in the middle of the supporting baffle 10 to be clamped and fixed with the exhaust guide plate 4. This structure can fix the exhaust guide plate 4 through the supporting baffle 10, so that the exhaust guide plate 4 can be tilted and fixed. The supporting baffle 10 is horizontally arranged, and the supporting baffle 10 is clamped and fixed in the tempering furnace 8. This structure can form a flow space for gas discharge through the gap formed by the upper end of the supporting baffle 10 and the tempering furnace 8. An exhaust filter box 9 is movably clamped between the supporting baffle 10 and the tempering furnace 8. The exhaust filter box 9 of this structure is an existing gas The exhaust guide plate 4 cools down the heat flow, which can reduce the damage to the exhaust filter box 9.

[0024] Working principle: When the exhaust mechanism of the glass tempering furnace is used, first, the tempering furnace 8 is exhausted through the exhaust mechanism body 1 when it is working, and the motor 2 drives the impeller 602 to rotate in the induced draft fan 6, so that negative pressure is formed in the tempering furnace 8, so that the gas in the tempering furnace 8 flows upward, and the gas passes through the exhaust holes 501 on the guide baffle 5 and flows into the exhaust guide plate 4. The grid structure formed by the exhaust guide plate 4 and the exhaust holes 501 makes the gas evenly distributed. At the same time, the exhaust guide plate 4 is tilted to guide the airflow, and the heat exchange pipe 401 in the exhaust guide plate 4 exchanges heat with the heat in the gas to achieve gas cooling treatment, and then The gas enters the exhaust filter box 9 for filtering and impurity removal, and the heat exchange tube 401 merges into the main heat exchange tube 11.
