[0031] The present utility model provides a kiln waste gas conveying device, as Figure 1 shown, the kiln 40 waste gas conveying device in this embodiment includes a pipeline assembly, a gas guiding assembly, and a valve 20 assembly. Both the gas guiding assembly and the valve 20 assembly are connected to the pipeline assembly, so as to be able to introduce the high-temperature waste gas inside the kiln 40 into the high-temperature device 41. Hereinafter, the specific structures and connection relationships of the above-mentioned various parts of the kiln waste gas conveying device according to the present utility model will be described in detail.

[0032] It should be noted that the high-temperature device 41 essentially refers to a device that uses high-temperature gas as a drying source or a heating source, including but not limited to a vibrating dryer. In addition, as Figure 1As shown, a pre-replacement chamber and a post-replacement chamber are respectively arranged at both ends of the kiln 40 in the extending direction. Materials enter the interior of the kiln 40 from the pre-replacement chamber, and after being sintered in the kiln 40, they are then led out from the post-replacement chamber. Along the extending direction of the kiln 40, a heating zone, a heat preservation zone, and a cooling zone are sequentially arranged inside it; further, the oxygen or air necessary for the sintering of the kiln 40 enters the interior of the kiln 40 from the bottom and side of the kiln 40 (not shown in this structural diagram). The kiln 40 in this embodiment is an existing device, so its specific structure and working principle will not be elaborated on further.

[0033] As Figure 1 shown, since the oxygen or air necessary for the kiln 40 enters the interior of the kiln 40 from the bottom and side of the kiln 40, the conveying device in this embodiment is arranged at the top of the kiln 40. In this way, the exhaust gas inside the kiln 40 can be effectively led out without affecting the normal working state of the kiln 40. Specifically, the pipeline assembly in this embodiment includes a plurality of intake pipes 10 located at the top of the kiln 40, and these intake pipes 10 are distributed at both ends of the kiln 40 in the extending direction, that is, the intake pipes 10 are communicated with the heating zone and the cooling zone. The heat preservation zone of the kiln 40 is the main sintering area for raw materials, and such an arrangement can ensure the sintering quality of the raw materials.

[0034] It should be noted that the temperature of the exhaust gas at the heating zone and the cooling zone of the kiln 40 is also high enough to meet the requirements of the high-temperature device 41. In addition, the shape, size, quantity, and specific installation position of the above intake pipes 10 are not fixed and should be determined comprehensively according to actual situations such as the volume of high-temperature gas required by the high-temperature device 41. For example, in this embodiment, three intake pipes 10 formed in a cylindrical structure are provided, and their lengths are different from each other; or the intake pipe 10 can also be formed into a square pipe as long as it is convenient for the transportation of high-temperature exhaust gas.

[0035] Further, each intake pipe 10 is formed with a plurality of air inlets, and the plurality of air inlets are spaced along the length direction of the intake pipe 10 (the length direction of the intake pipe 10 is the same as the extending direction of the kiln 40). Each air inlet is communicated with the kiln 40 through a corresponding first branch pipe 11 to form the air inlet end of the pipeline assembly. Such an arrangement can effectively ensure the transportation efficiency of high-temperature exhaust gas and the sufficiency of the discharge of high-temperature exhaust gas. Specifically, although not shown in the figure, through holes corresponding to the air inlets are formed at the top end of the kiln 40. The two ends of the first branch pipe 11 are respectively connected to the air inlet and the corresponding through hole, and the connection manner of the first branch pipe 11 with the air inlet and the through hole is not fixed. For example, welding can be used to ensure the sealing performance of this conveying device. Preferably, the air inlet is formed at the bottom of the intake pipe 10 to facilitate improving the transportation efficiency of the exhaust gas.

[0036] Furthermore, at the first end in the length direction of the intake pipe 10 in this embodiment (i.e., the end of each intake pipe 10 close to the heat preservation area of the kiln 40), an opening is formed, through which the internal space of the intake pipe 10 can be communicated with the external space. A corresponding valve 20 (which can be an electromagnetic valve, etc., and there is no limit to the type and specification of this valve 20) is arranged at this opening, so that by controlling the opening degree of this valve 20, the flow rate of external air entering the intake pipe 10 can be adjusted, and then the temperature and flow rate during the transportation of high-temperature waste gas can be adjusted. In this way, the flexibility during the operation of this transportation device is effectively increased, so that this transportation device can adapt to the air supply requirements of different high-temperature devices 41 under different working conditions.

[0037] In this embodiment, as Figure 1 shown, a gas guide pipe 12 is also connected to the second end in the length direction of the intake pipe 10, and this gas guide pipe 12 is arranged perpendicular to the intake pipe 10. The above gas guide assembly includes a plurality of exhaust fans 30, and a plurality of exhaust fans 30 are correspondingly arranged at one end of each gas guide pipe 12 close to the intake pipe 10. In addition, the pipeline assembly further includes an outlet pipe 14, and one end of each gas guide pipe 12 away from the intake pipe 10 is communicated with the outlet pipe 14 through a second branch pipe 13; and the first end of this outlet pipe 14 is communicated with the air inlet of the high-temperature device 41 to form an air outlet end.

[0038] In addition, the gas guide assembly further includes a dust filter 31 and a pressure fan 32 connected to the gas guide pipe 12, and the two of them are arranged at the main path of the outlet pipe 14 (i.e., the position where a plurality of second branch pipes 13 converge), so as to cooperate with the above exhaust fans 30 to extract high-temperature waste gas. The pressure fan 32 is closer to the high-temperature device 41 than the dust filter 31. The high-temperature waste gas can be filtered through the dust filter 31 to avoid the accumulation of dust and fine particles in the pressure fan 32 and the high-temperature device 41, resulting in mechanical failures and unnecessary cleaning costs, etc.; the pressure fan 32 can adjust the internal pressure of the pipeline assembly by adjusting the operating power and can compress the waste gas, so as to meet the intake pressure requirements of the high-temperature device 41.

[0039] According to the kiln waste gas transportation device of the present invention, the high-temperature waste gas generated in the kiln 40 can be introduced into the high-temperature device 41 (such as the vibrating dryer described in the background art) through the pipeline assembly and the gas guide assembly connected to this pipeline assembly. The high-temperature device 41 uses this high-temperature waste gas as a drying source, so that the secondary utilization of energy is effectively realized and environmental protection is achieved. Further, this transportation device is also provided with a valve 20 assembly communicated with the pipeline assembly, which can adjust the opening degree of the pipeline assembly, so that the temperature and flow rate of the high-temperature waste gas can be flexibly controlled according to the actual production situation.

[0040] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit it. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed by the present application can still modify the technical solutions recorded in the foregoing embodiments or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
