When the negative pressure is increased, some powder is sucked away, affecting product quality. When the negative pressure is decreased, the flue gas recovery effect is affected. The main problem with the existing kneading pot flue gas purification process is that the dry material mixing and paste mixing are purified in the same area. This purification method results in significant powder loss in the dry material mixing formula, which not only affects the formula but also has a significant impact on product quality.

[0017] like Figure 1 As shown, a carbon kneading pot asphalt smoke diversion and recovery device includes a smoke collecting pipe 4, one end of the smoke collecting pipe 4 is connected to the kneading pot, and the other end of the smoke collecting pipe 4 is connected to the dust collector, an electric butterfly valve 3 is provided on the smoke collecting pipe 4, a dust pipe 1 is provided above the smoke collecting pipe 4, and a manual butterfly valve 2 is provided on the dust pipe 1; specifically, the diameter Φ of the smoke collecting pipe 4 is 300 mm, the diameter Φ of the dust pipe 1 is 100 mm, the model of the electric butterfly valve 3 is DN300 mm, and the model of the manual butterfly valve 2 is DN100 mm.
[0018] The diameter of the dust duct 1 is smaller than the diameter of the smoke collection duct 4 .
[0019] The smoke collecting pipe 4 includes a first pipe 4 - 1 and a second pipe 4 - 2 , and the electric butterfly valve 3 is arranged between the first pipe 4 - 1 and the second pipe 4 - 2 .
[0020] Both ends of the electric butterfly valve 3 are connected to the first pipeline 4 - 1 and the second pipeline 4 - 2 through flanges.
[0021] One end of the dust duct 1 is connected to the first duct 4 - 1 , and the other end of the dust duct 1 is connected to the second duct 4 - 2 .
[0022] The dust duct 1 is configured to be arc-shaped.
[0023] A movable door 5 is installed on the smoke collecting pipe 4 at a position close to the end of the dust pipe 1. The dust can be cleaned out by opening the movable door 5.
[0024] The use process of this utility model is as follows:
[0025] When the kneading pot is kneading the dry materials, the electric butterfly valve 3 closes and the manual butterfly valve 2 opens (the valve opening is adjustable). The dust-mixed flue gas enters the dust duct 1. Because the dust duct 1 is designed in an arc shape and its diameter is much smaller than that of the smoke collection duct 4, the dust in the powder is sucked into the second duct 4-2 of the smoke collection duct 4 through the dust duct 1. It is then transported to the dust collector through the second duct 4-2. The dust in the dust collector passes through the dust collector filter bag and is collected by the ash conveying screw in the dust bin, and then enters the production line for secondary use. A movable door is installed near the end of the dust duct 1. If dust blockage occurs, the operator can use the movable door to clear the duct and resolve the blockage.
[0026] When the kneading pot is in wet mixing operation, the electric butterfly valve 3 opens, and a large amount of flue gas enters the smoke collecting pipe 4 through the electric butterfly valve 3, and is transported to the dust collector through the smoke collecting pipe 4, which completely solves the problem of the kneading pot flue gas recovery affecting the workplace environment. After the transformation, the effect is good and the problem of poor workplace environment is completely solved.
[0027] The utility model redesigns the asphalt fume diversion and recovery pipeline of a carbon kneading pot to achieve the purpose of fume and gas diversion and realize the stability of process formula. It is applied to the cathode and anode forming system in the production of carbon materials for aluminum, and has guiding significance for the fume recovery of the carbon kneading pot, especially in the kneading and purification of dry materials and pastes of carbon cathodes and anodes for aluminum, and the control of process parameters of carbon products.
[0028] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
