[0002] At present, during the production mixing process, the Sigma fly ash mixer is generally prone to steam blockage of the ash outlet. During the fly ash mixing process, a large amount of steam is generated due to the full reaction of the chelating agent solution and the fly ash in the mixing process, thereby causing the ash outlet to be easily blocked, resulting in the production efficiency of the fly ash chelate being reduced, and thereby affecting the normal operation of the equipment. In view of this problem, an effective steam exhaust device is urgently needed to ensure the stable operation of the mixer. CONTENT OF THE UTILITY MODEL

[0003] In order to solve the above problems, the present application provides a forced steam exhaust device and a Sigma fly ash mixer, which forcibly inhales the steam generated in the mixing process of the Sigma fly ash mixer into the steam exhaust device for cooling and removal treatment, the inlet channel serves as a gas conveying device, and the steam exhaust fan serves as a flow guide. The device is suitable for most Sigma series mixers, and the inlet channel diameter can be changed according to the mixer model.

[0004] Specifically, the present application provides a forced steam exhaust device for steam exhaust of a Sigma fly ash mixer, comprising:

[0005] an inlet channel, one end of which is connected to the steam exhaust hole of the Sigma fly ash mixer;

[0006] a steam exhaust fan, one end of which is connected to the other end of the inlet channel, and which is used to form a negative pressure for steam exhaust of the Sigma fly ash mixer; and

[0008] As a preferred scheme, the steam exhaust fan comprises:

[0009] a impeller cover, comprising a first mounting hole and an air outlet; and

[0016] As a preferred solution, the center of the front disc of the impeller is provided with an air inlet hole.

[0017] As a preferred solution, the blades are in an arc shape and extend from the edge of the air inlet hole to the outer edge of the front disc and the rear disc of the impeller.

[0018] As a preferred solution, the number of blades is 8.

[0019] As a preferred solution, the air inlet channel comprises:

[0020] A cylindrical body is used for the exhaust of the Sigma fly ash mixer;

[0021] A first connecting disc is arranged at the left end of the cylindrical body and is used to connect the Sigma fly ash mixer; and

[0022] A second connecting disc is arranged at the right end of the cylindrical body and is used to connect the impeller cover.

[0023] As a preferred solution, the first connecting disc is provided with a first connecting hole arranged in a ring shape and uniformly distributed, and the first connecting hole is matched with a second mounting hole on the Sigma fly ash mixer;

[0030] Compared with the prior art, the application has the following beneficial effects:

[0031] By installing this exhaust device, high-temperature gases generated during daily production can be effectively removed, thereby improving production efficiency. This is because during the daily mixing process of fly ash, a large amount of high-temperature gas is easily generated during the mixing and stirring of fly ash and solution. This application can solve the problem that the exhaust holes of the original fly ash Sicoma mixer are easily blocked and the poor exhaust results in the high-temperature gas filling the inside of the mixer, which easily makes the inside damp and blocks the ash discharge channel, thus improving production efficiency. Moreover, this device is simple in design and easy to install, reducing maintenance costs and indirectly reducing the maintenance costs of the mixer. Attached Figure Description
