Problems solved by technology

[0007] The existing defect of above-mentioned technology: the purpose of developing the pulsating vacuum jet pump nozzle powder automatic rotation distributing device is: the jet nozzle has the characteristics of rotatability and asymmetric structure, therefore, it can produce periodically changing pulsating vacuum, while pulsating The vacuum will cause the solid powder to relax and accelerate the unstable pulsation state in the process of entering the jet nozzle, so that the powder can be evenly distributed before entering the jet area, without accumulating into blocks, and the fluidity is good, avoiding "lumping" ", and prevent the jet pump system from running dry, and also prevent the jet nozzle efficiency bottleneck
Therefore, there are obvious defects in the above-mentioned technology

Abstract

The invention relates to a device for automatically rotating the nozzle powder of a pulsating vacuum jet pump. A left bearing support frame and a right bearing support tube are fixedly installed at intervals on the top of a fixed plate. The hollow shaft is rotated, and a rotating wheel is installed in the middle of the hollow shaft through a flat key. The right end of the hollow shaft is coaxially connected to the inlet of the pressurization chamber of the nozzle of the jet pump; a jet nozzle is fixed coaxially in the hollow shaft. The right end of the nozzle is inserted into the pressurization chamber connected to the nozzle of the jet pump, and the port at the right end of the jet nozzle has an asymmetric structure. The jet nozzle of this device has the characteristics of rotatability and asymmetric structure, which can generate periodically changing pulsating vacuum, so that the powder can be evenly distributed before entering the jet area, without accumulation into blocks, and has good fluidity, avoiding " lumps” and prevents the jet pump system from running dry.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and relates to a solid-liquid mixed jet pump, in particular to an automatic rotating distributing device for nozzle powder of a pulsating vacuum jet pump. Background technique [0002] The jet pump is an important unit operation in the chemical industry. It is a fluid machinery and mixing conveying reaction equipment that uses the strong shear and violent turbulent diffusion between the high-speed jet and the absorbed fluid to transfer energy and quality. Due to its simple structure, stable process, convenient installation, strong process adaptability, and low production cost, its application range is becoming wider and wider. In some vacuum conditions, the jet pump can replace the water ring type, rotary vane type, Reciprocating vacuum pump. [0003] The research and application of jet pumps have a long history. As early as the 16th century, people discovered the mixing phenomenon of jets. Wi...
