Therefore, it is necessary to design a conveying and processing device with strong conveying capacity and stability. Utility Model Content

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should also be noted that, for the convenience of description, the accompanying drawings only show parts related to the utility model rather than all structures.

[0017] Reference Figure 1 and Figure 2 A Topcon process poly tail gas transportation and treatment device of this embodiment includes a waste gas transportation pipeline 1, a gas source pipeline 2, a combustion barrel 3 and a dust collector 4. The waste gas transportation pipeline 1 is interspersed with multiple sections of inclined tee pipes 5. The end of the waste gas transportation pipeline 1 is connected to the combustion barrel 3, and the combustion barrel 3 is connected to the dust collector 4 through a pipeline. The gas source pipeline 2 is connected to the waste gas transportation pipeline 1 through multiple auxiliary blowing pipes 6, and the auxiliary blowing pipes 6 are respectively connected to the waste gas transportation pipeline 1 at the front end of the inclined tee pipe 5 and the front end of the combustion barrel 3.

[0018] Specifically, two sections of inclined tee pipes 5 are interspersed on the exhaust gas conveying pipe 1, and the straight pipe 51 of the inclined tee pipe 5 is connected to the exhaust gas conveying pipe 1 through a flange 53. A quick-opening blind plate 54 is provided on the inclined branch pipe 52 of the inclined tee pipe 5. The inclined branch pipe 52 is inclined at 45° relative to the exhaust gas conveying pipe 1. The quick-opening blind plate 54 is a mechanical device used on the circular opening of a pressure pipe or a pressure vessel, and can be quickly opened or closed. It is generally composed of a cylinder flange, a head cover, a hook ring or a clamp, a sealing ring, a safety interlocking mechanism, an opening and closing mechanism, a rotating arm and a short section (when necessary) and other components. The quick-opening blind plate 54 on the inclined branch pipe 52 can be opened to check the accumulation of dust and particulate matter inside the pipe, so as to facilitate unblocking.

[0019] Furthermore, the blow-assisting pipe 6 is inserted and connected at an angle of 45 degrees below the exhaust gas delivery pipe 1. In this embodiment, three blow-assisting pipes 6 are provided, which are respectively connected to the exhaust gas delivery pipe 1 at the front end of the two inclined tees 5 and the front end of the combustion barrel 3. Each blow-assisting pipe 6 is provided with a manual control valve 61, which can adjust and control the blow-assisting flow of each blow-assisting pipe 6 individually as needed.

[0020] At the same time, a manual stop valve 21 is provided at the air inlet end of the gas source pipeline 2, and a pneumatic valve 22 is provided at the rear end of the manual stop valve 21. Nitrogen is introduced into the gas source pipeline 2, and the nitrogen is introduced into the exhaust gas delivery pipeline 1 through each blow-assisting pipe 6 to dredge and blow the exhaust gas delivery pipeline 1. The nitrogen source is controlled on and off by the manual stop valve 21 and the pneumatic valve 22. An automatic controller is provided in the pneumatic valve 22, which is automatically controlled according to a preset working logic.

[0021] Working principle: manually open the manual stop valve 21 on the gas source main pipe 2 in advance, and manually adjust the control valve 61 on the blowing-assisting pipe 6 to the opening of the required blowing-assisting flow rate. When a large amount of particulate matter is transported under negative pressure, the pneumatic valve opens the automatic control and operates according to the preset working logic. Multiple blowing-assisting pipes 6 transport and blow synchronously. The staff can observe the transportation status through the quick-opening blind plate 53 and adjust the blowing-assisting flow rate and control logic in time.
