Embodiment Construction

[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0051] A compound vibrating jet pump nozzle feed inlet distributing device, including a hopper 1, a jet pump nozzle 3 and a distributing device 2, the jet pump nozzle is a three-way structure composed of a slurry booster chamber A, a vacuum mixing chamber B and an expansion chamber C , the slurry pressurization chamber is made with a slurry inlet, the vacuum mixing chamber is made with a powder inlet, and the expansion chamber is made with an outlet; the powder inlet is connected to the bottom of the hopper, and the hopper is a conical funnel structure with a large upper part and a smaller lower part;

[0052] In the hopper, there are three kinds of distribution devices arranged in sequence from top t...

Abstract

The invention relates to a composite vibrating jet pump nozzle feed inlet distributing device, comprising a hopper, a jet pump nozzle and a distributing device, the powder inlet of the jet pump nozzle is connected to the bottom of the hopper, and the hopper is a conical funnel structure with a large upper part and a smaller lower part , is characterized in that: a forced vibration type distribution device, an elastic vibration type distribution device and a forced vibration type jet pump nozzle inlet distribution device are sequentially arranged in the hopper from top to bottom. The advantage of the device is that the powder that needs to be added does not raise dust, does not cause the concentration of the slurry in the nozzle of the jet pump to be locally too high, and is safe and reliable. The composite vibrating jet pump nozzle material inlet distribution device can be used to increase the efficiency of the jet pump system, and can also be directly used for auxiliary stirring and distribution of large and medium-sized solid powder feeding devices without a jet pump system. Therefore, the device can also be widely used in solid-liquid mixed transportation in the fields of petroleum, chemical industry, medicine, food and the like.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to a jet pump, in particular to a composite vibrating jet pump nozzle feed opening distributing device. 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 conveyi...
