[0002] A jet pump is a fluid power pump. A fluid power pump has no mechanical transmission and mechanical working parts. It uses the energy of another working fluid as a power source to transport low-energy liquids. It is safe to use it to pump flammable and explosive materials. A jet vacuum pump is a device that uses a high-speed jet through a nozzle to remove gas from a container to obtain a vacuum. It is also called a jet vacuum pump. In chemical production, the purpose is often to create a vacuum.

[0003] In the prior art, in order to ensure the stability of the vacuum degree in the vacuum chamber, a manhole is provided on the side of the steam jet pump. The cover is opened regularly and a high-pressure water gun is used to clean the dust accumulated in the steam jet pump. Generally, the cover is fixedly connected to the sewage pipe with several bolts.

[0004] However, the steam jet pump requires operators to remove and install multiple bolts before and after ash discharge, which not only increases labor intensity, but also reduces ash discharge efficiency, thereby delaying production progress. To this end, the utility model proposes a steam jet pump ash discharge device for solving the above problems. Utility Model Content
