Abstract

The invention relates to an accompanying vibration type distribution device for a jet pump nozzle feed port. An accompanying vibration type distribution device is mounted at the lower part in a hopperand comprises a lifting rod, a butterfly nut, a spring, a spring seat, a steel wire cage and lifting hooks, wherein the lifting rod is of a vertical round rod structure, an external thread is formedat the upper end of the lifting rod, and the butterfly nut is mounted at the upper end of the lifting rod in an engaged manner; a gasket, a spring press block, the spring and the spring seat are movably mounted in the middle of the lifting rod in a sleeving manner from top to bottom in sequence, the steel wire cage is fixedly mounted on the spring seat, is of a netted circular truncated cone structure and is mounted in the hopper in a limited manner, and multiple lifting hooks are radially and uniformly distributed and fixedly mounted at the lower end of the lifting rod. According to the device, blockage, dust raising and overhigh local concentration of slurry in a jet pump nozzle due to powder required to be added can be prevented, additional energy and power are also not needed, and thedevice is safe, reliable, simple in structure, convenient to mount and wide in applicable range.

Description

technical field [0001] The invention belongs to the field of jet pumps, in particular to a distributing device for a nozzle feeding port of a vibration-accompanied jet pump. Background technique [0002] The jet pump is an important unit operation in the chemical industry. It is a fluid machine and a mixed conveying recoil device that transfers energy and quality by means of strong shear and violent turbulent diffusion between the high-speed jet and the absorbed fluid. 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. What this patent describes is a solid-liquid mixing jet pump, which has dual functions of solid-liquid mixing and conveying. Its most notable feature is the conveying of solid powder, such as conveying of cornstarch. If ...
