[0002] At present, the flue gas from industrial kilns is generally discharged directly into the atmosphere, but the flue gas emitted by different kilns contains different components, such as dust content, sulfur content, etc. The emission of these flue gases not only pollutes the surrounding environment, but also threatens the health of job operators and local residents. Therefore, the flue gas generated by industrial kilns needs to be discharged into the desulfurization and dust removal device through the smoke exhaust device.

[0003] The smoke exhaust device in the prior art is generally an annular sliding cover type smoke exhaust device, which mainly installs an annular sliding cover on the upper part of the annular flue, the annular sliding cover is connected to the dehumidification pipe, and the annular sliding cover moves synchronously with the kiln. However, this type of annular sliding cover type smoke exhaust device system is relatively complicated, and requires annular guide rails, annular sliding cover wheel groups, etc., which makes the entire system relatively large and heavy, increasing the burden on the movement of the kiln, and because the annular sliding cover has more wheel groups, it also leads to an increase in the failure rate in later use, and the later maintenance costs are also high; in addition, there are gaps between the two sides of the entire circle of annular sliding covers and the annular flue, and the gaps lead to poor sealing, so that a large amount of air enters the annular flue and is sent into the desulfurization and dust removal device by the dehumidification and desulfurization fan, resulting in an increase in the oxygen content in the exhaust flue gas, which increases the difficulty of the flue gas emission meeting the emission standards and increases the operating costs of the flue gas purification system.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0027] The purpose of the present invention is to provide a flip-top fixed-point smoke exhaust device to solve the technical problems of poor sealing of the annular flue, easy entry of air, high failure rate of the smoke exhaust device and high maintenance cost.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-4As shown, the present invention provides a flip-top fixed-point smoke exhaust device, comprising a connecting rod, a cover-opening pressure rod 2, a collecting pipe 3 and a plurality of flip covers 4; the collecting pipe 3 has a bottom opening, and the bottom opening can be one or more. When there is one bottom opening, the bottom opening extends to both ends of the collecting pipe 3, so that when the flip cover 4 is opened, the bottom opening and the smoke inlet connect the collecting pipe 3 and the annular flue 7. When there are multiple bottom openings, it is necessary to ensure that the distance between adjacent bottom openings is consistent with the distance between adjacent flip covers 4, so that the flip cover can be opened. 4 is opened, the bottom opening and the smoke inlet connect the collecting pipe 3 and the annular flue 7, and a connecting port for connecting with the smoke outlet of the dehumidification pipe 6 is provided on the top. The collecting pipe 3 is fixedly connected with the dehumidification pipe 6 and connects each dehumidification pipe 6. The smoke in the dehumidification pipe 6 is discharged into the collecting pipe 3 through the smoke outlet and the connecting port. The upper top surface of the annular flue 7 is provided with a plurality of smoke inlets. The smoke in the collecting pipe 3 is discharged into the annular flue 7 through the opening at the bottom of the collecting pipe 3 to purify the smoke. Each smoke inlet is provided with a flip cover 4, and the flip cover is One side of 4 is hinged to the top surface of the annular flue 7, and the flip cover 4 can open or close the smoke inlet, thereby reducing the air entering the annular flue 7, so that the sealing effect of the annular flue 7 is good. A flip cover pressure rod 41 is provided on the flip cover 4, one end of the connecting rod is connected to the kiln 5, and the other end is connected to the cover-opening pressure rod 2. The flip cover pressure rod 41 is used to drive the opening of the flip cover 4; the cover-opening pressure rod 2 and the collecting pipe 3 both move synchronously with the kiln 5. When the kiln 5 drives the collecting pipe 3 to move toward the flip cover 4, the cover-opening pressure rod 2 can squeeze the flip cover pressure rod 41, so that the flip cover pressure rod 4 1 drives the flap 4 to open, and the opening at the bottom of the collecting pipe 3 covers the smoke inlet; when the kiln 5 drives the collecting pipe 3 to gradually move away from the flap 4, the pressure of the cover-opening pressure rod 2 on the flap pressure rod 41 is reduced, and the flap 4 falls due to gravity to close the smoke inlet, thereby realizing instant opening and closing of the flap 4, avoiding excessive gap between the dehumidification pipe 6 and the annular flue 7, resulting in poor sealing of the annular flue 7, and increasing the difficulty of smoke emission meeting the emission standards. In addition, the structure of the flap fixed-point smoke exhaust device is relatively simple, which effectively reduces the failure rate and maintenance costs.

[0030] Specifically, the connecting rod includes a plurality of horizontal rods 1 and a plurality of vertical rods 12, one horizontal rod 1 is connected to a corresponding vertical rod 12, the horizontal rod 1 is arranged parallel to the horizontal plane, and the vertical rod 12 is arranged perpendicular to the horizontal plane, one end of the horizontal rod 1 is connected to the kiln 5, and the other end is connected to the upper end of the vertical rod 12, and the lower end of the vertical rod 12 is fixedly connected to the opening cover pressure rod 2, and the kiln 5 and the opening cover pressure rod 2 are realized through the connecting rod, and the synchronous movement of the opening cover pressure rod 2 and the kiln 5 is realized, but the connecting rod of the flip cover fixed-point smoke exhaust device provided by the present invention is not limited to the above structure, as long as the opening cover pressure rod 2 can move synchronously with the kiln 5 and the connection is stable.

[0031] The cover opening pressure rod 2 comprises a cover opening section 21, a pressing section 22 and a cover closing section 23 which are fixedly connected end to end in sequence. The cover opening section 21 is arranged at a position close to the forward direction of the kiln 5, that is, the cover opening section 21 is arranged close to the front end of the collecting pipe 3.

[0032] The rear end of the cover opening section 21 is fixedly connected to the extrusion section 22, and the projection line of the front end of the cover opening section 21 on the horizontal plane extends in the direction away from the kiln 5, and the angle between the cover opening section 21 and the horizontal plane is an acute angle. The distance between the cover opening section 21 and the ground gradually decreases from the front end of the cover opening section 21 to the rear end of the cover opening section 21. The cover opening section 21 can squeeze the flap pressure rod 41 toward the kiln 5. When the rear end of the cover opening section 21 contacts the flap pressure rod 41, the flap 4 is fully opened, and the smoke entering the collection pipe 3 from the dehumidification pipe 6 enters the annular flue 7 through the smoke inlet below the flap 4, thereby achieving smoke purification;

[0033] The front end of the closing section 23 is fixedly connected to the extrusion section 22, and the projection line of the rear end of the closing section 23 on the horizontal plane extends in the direction away from the kiln 5, and the angle between the closing section 23 and the horizontal plane is an acute angle. The distance between the closing section 23 and the ground gradually increases from the front end of the closing section 23 to the rear end of the closing section 23. The closing section 23 can gradually reduce the extrusion force on the flip cover pressure rod 41, so that the flip cover 4 is gradually closed. When the front end of the closing section 23 leaves the flip cover pressure rod 41, the flip cover 4 is closed. At this time, the collecting pipe 3 no longer covers the top of the smoke inlet, and the flip cover 4 closes the smoke inlet to prevent a large amount of air from entering the annular flue 7 through the smoke inlet.

[0034] The flip cover 4 and the upper top surface of the annular flue 7 are hingedly connected by a rotating shaft 42, but the hinge method between the flip cover 4 and the upper top surface of the annular flue 7 of the flip cover fixed-point smoke exhaust device provided by the present invention is not limited to the rotating shaft 42. As long as one side of the flip cover 4 can be hingedly connected to the upper top surface of the annular flue 7, so that the flip cover 4 can be opened and closed, thereby opening or closing the smoke inlet.

[0035] The flap 4 is rectangular, and a reinforcing rod 44 is provided in the middle of the flap 4. The reinforcing rod 44 can make the structure of the flap 4 more stable and prevent the flap 4 from being deformed. However, the shape of the flap 4 of the cover-type fixed-point smoke exhaust device provided by the present invention is not limited to a rectangle, as long as the flap 4 can cover the smoke inlet and be easy to flip.

[0036] The rotating shaft 42 is arranged on the side wall of the flap 4 close to the annular flue 7. The rotating shaft 42 is hinged to the support ear 43 fixed on the top surface of the annular flue 7. One side of the flap 4 is fixedly connected to the rotating shaft 42, so that the flap 4 can rotate with the rotating shaft 42.

[0037] The flip cover pressure rod 41 is fixedly arranged at the middle part of the rotating shaft 42, and the flip cover pressure rod 41 is perpendicular to the horizontal plane. Under the extrusion of the cover opening pressure rod 2, the flip cover pressure rod 41 can rotate toward the kiln 5 direction to drive the flip cover 4 to be fully opened. When the end of the cover opening section 21 close to the extrusion section 22 contacts the flip cover pressure rod 41, the flip cover pressure rod 41 flips to be parallel to the horizontal plane, the flip cover 4 is perpendicular to the horizontal plane, the flip cover 4 is fully opened, and the smoke enters the annular flue 7 through the smoke inlet. When the end of the cover closing section 23 away from the extrusion section 22 contacts the flip cover pressure rod 41, the flip cover pressure rod 41 flips to be perpendicular to the horizontal plane, the flip cover 4 is parallel to the horizontal plane, the flip cover 4 is fully closed, and the smoke inlet is sealed. When the flip cover 4 is opened, the contact point between the cover opening pressure rod 2 and the flip cover pressure rod 41 is higher than the contact point between the cover opening pressure rod 2 and the flip cover pressure rod 41 when the flip cover 4 is closed.

[0038] There are 12 flaps 4, but the flaps 4 of the flap fixed-point smoke exhaust device provided by the present invention are not limited to 12. Those skilled in the art can adaptively change the number of flaps 4 according to actual smoke conditions and the number of smoke inlets of the annular flue 7.

[0039] The present specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
