[0001] The utility model relates to the technical field of secondary combustion chambers, and specifically relates to an emergency discharge device for a secondary combustion chamber. Background Technique
[0002] With the development of industry, the generation of solid waste has also increased. The incineration method can realize the resource utilization, reduction and harmless treatment of solid waste. However, in the treatment process of the incineration method, it is necessary to ensure that there is an emergency discharge device on the secondary combustion chamber to ensure the safe operation of the incineration system. When the system makes an emergency stop, it is necessary to quickly and flexibly open the lid of the emergency discharge device.
[0003] During the use of the existing secondary combustion chamber, there is no emergency pressure relief device in its emergency discharge pipe. When an explosion occurs inside the secondary combustion chamber, the emergency discharge door at the emergency discharge port has explosion-proof performance and can withstand the pressure, but it is easy to damage the connecting pipe, resulting in the inability of the emergency discharge port to be used normally. For this reason, we propose an emergency discharge device for a secondary combustion chamber to solve the above problems. Content of the Utility Model

[0006] Further preferably, a third sliding plate is slidably connected inside the second pressure relief box, and a second spring is fixedly connected between the third sliding plate and the second pressure relief box.
[0007] Further preferably, a touch-sensitive switch is fixedly connected to the left inner wall of the second pressure relief box, and an alarm is fixedly connected to the left side of the emergency discharge port, so that when the third sliding plate slides leftward and touches the touch-sensitive switch, the alarm sounds.

[0011] Further preferably, the first spring is movably sleeved on the outside of the vertical rod.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: When deflagration occurs in the secondary combustion chamber of the present utility model, a large amount of gas is generated, the pressure in the connecting pipe increases, and the gas flows into the first pressure relief box through the first through hole and the second through hole. Under the action of the pressure, the first sliding plate slides downward, the second sliding plate slides upward, and the two vertical rods drive the corresponding baffles to move towards each other, and the first spring is stretched. When the pressure is still very high, the first sliding plate and the second sliding plate contact the middle position of the first pressure relief box. The aperture of the third through hole is larger than the sum of the thicknesses of the first sliding plate and the second sliding plate, so that the gas enters the second pressure relief box through the third through hole, the third sliding plate slides to the left, and the second spring is compressed. When the third sliding plate moves to the left side of the pressure relief hole, the pressure inside the pressure relief connecting pipe passing through the pressure relief hole decreases. If the pressure increases rapidly, when the third sliding plate continues to move to the left and touches the touch-sensitive switch, the touch-sensitive switch controls the alarm to sound, prompting the staff to open the emergency discharge door. The setting of the filter screen can filter the impurities generated by the combustion in the secondary combustion chamber, so that the pressure inside the connecting pipe can be relieved through the pressure relief hole. At the same time, when the pressure generated by deflagration increases rapidly, the touch-sensitive switch can control the alarm to sound to prompt the staff, and the safety is relatively high.

[0018] Embodiment
[0019] Please refer to Figures 1-3, the present utility model provides a technical solution: an emergency discharge device for a secondary combustion chamber, including an emergency discharge port 1.

A connecting pipe 2 is connected to the top of the emergency discharge port 1. A first pressure relief box 3 is fixedly connected to the left side of the connecting pipe 2. A first through hole 4 and a second through hole 5 are provided through between the first pressure relief box 3 and the connecting pipe 2. A first slide plate 6 and a second slide plate 7 are slidably connected inside the first pressure relief box 3. Vertical rods 8 are fixedly connected to the sides of the first slide plate 6 and the second slide plate 7 that are away from each other. The ends of the two vertical rods 8 that are away from each other extend outside the first pressure relief box 3 and are fixedly connected to a baffle 9. A first spring 10 is fixedly connected between the baffle 9 and the first pressure relief box 3. A second pressure relief box 11 is fixedly connected to the left side of the first pressure relief box 3. A plurality of pressure relief holes 21 are provided on the outer side of the second pressure relief box 11. A third through hole 12 is provided through between the first pressure relief box 3 and the second pressure relief box 11. When an explosion occurs in the secondary combustion chamber, a large amount of gas is generated, the pressure in the connecting pipe 2 increases, and the gas flows into the first pressure relief box 3 through the first through hole 4 and the second through hole 5. Under the action of the pressure, the first slide plate 6 slides downward, the second slide plate 7 slides upward, the two vertical rods 8 drive the corresponding baffles 9 to move towards each other, and the first spring 10 is stretched. When the pressure is still very high, the first slide plate 6 and the second slide plate 7 contact the middle position of the first pressure relief box 3. The aperture of the third through hole 12 is larger than the sum of the thicknesses of the first slide plate 6 and the second slide plate 7, so that the gas enters the second pressure relief box 11 through the third through hole 12, the third slide plate 13 slides to the left, and the second spring 14 is compressed. When the third slide plate 13 moves to the left side of the pressure relief hole 21, the pressure inside the connecting pipe 2 is reduced through the pressure relief hole 21. If the pressure increases rapidly, when the third slide plate 13 continues to move to the left and touches the touch-sensitive switch 15, the touch-sensitive switch 15 controls the alarm 16 to sound, prompting the staff to open the emergency discharge door 17. The setting of the filter screen 19 can filter the impurities generated by the combustion in the secondary combustion chamber, so as to relieve the pressure inside the connecting pipe 2 through the pressure relief hole 21. At the same time, when the pressure generated by the explosion increases rapidly, the touch-sensitive switch 15 can control the alarm 16 to sound to prompt the staff, and the safety is relatively high.
[0020] In this embodiment, specifically: A third slide plate 13 is slidably connected inside the second pressure relief box 11. A second spring 14 is fixedly connected between the third slide plate 13 and the second pressure relief box 11. The setting of the second spring 14 plays a role in resetting;
[0021] In this embodiment, specifically: A touch-sensitive switch 15 is fixedly connected to the left inner wall of the second pressure relief box 11. An alarm 16 is fixedly connected to the left side of the emergency discharge port 1, realizing that when the third slide plate 13 slides to the left and touches the touch-sensitive switch 15, the alarm 16 is controlled to sound;
[0022] In this embodiment, specifically: an emergency discharge door 17 is rotatably connected to the front side of the emergency discharge port 1 through a hinge, and the setting of the emergency discharge door 17 achieves the effect of emergency discharge;
[0023] In this embodiment, specifically: a handle 18 is fixedly connected to the front side of the emergency discharge door 17, and the setting of the handle 18 achieves the effect of facilitating gripping;
[0024] In this embodiment, specifically: a filter screen 19 is fixedly connected inside the connecting pipe 2, and the setting of the filter screen 19 achieves the effect of filtering;
[0025] In this embodiment, specifically: the first spring 10 is movably sleeved outside the vertical rod 8, and the setting of the first spring 10 achieves the effect of resetting.
[0026] When the present utility model is in operation: during use, when deflagration occurs in the secondary combustion chamber, a large amount of gas is generated, the pressure inside the connecting pipe 2 increases, and the gas flows into the first pressure relief box 3 through the first through hole 4 and the second through hole 5. Under the action of the pressure, the first slide plate 6 slides downward, the second slide plate 7 slides upward, and the two vertical rods 8 drive the corresponding baffles 9 to move towards each other, and the first spring 10 is stretched. When the pressure is still very high, the first slide plate 6 and the second slide plate 7 contact the middle position of the first pressure relief box 3. The aperture of the third through hole 12 is larger than the sum of the thicknesses of the first slide plate 6 and the second slide plate 7, so that the gas enters the second pressure relief box 11 through the third through hole 12. The third slide plate 13 slides to the left, and the second spring 14 is compressed. When the third slide plate 13 moves to the left side of the pressure relief hole 21, the pressure inside the connecting pipe 2 passing through the pressure relief hole 21 decreases. If the pressure increases rapidly, when the third slide plate 13 continues to move to the left and touches the touch-sensitive switch 15, the touch-sensitive switch 15 controls the alarm 16 to sound, prompting the staff to open the emergency discharge door 17. The setting of the filter screen 19 can filter the impurities generated by the combustion in the secondary combustion chamber, thus constituting an emergency discharge device for the secondary combustion chamber, which can relieve the pressure inside the connecting pipe 2 through the pressure relief hole 21. At the same time, when the pressure generated by deflagration increases rapidly, it can control the alarm 16 to sound through the touch-sensitive switch 15 to prompt the staff, and the safety is relatively high.
