Adjustable jet vacuum pump with good cleaning performance

Abstract

The invention relates to an adjustable jet vacuum pump with good cleaning performance, and belongs to the technical field of jet pumps used for pumping fluid by using the inertia of pumped fluid. The adjustable jet vacuum pump comprises a submersible pump, a jet device and a vacuum tank. The jet device comprises a jet box with an outlet; a left clamping plate and a right clamping plate are arranged in the jet box oppositely; a jet spraying nozzle is formed between the left clamping plate and the right clamping plate; the interval between the left clamping plate and the right clamping plate is 8-20 mm; the outlet end of the jet spraying nozzle is opposite to the outlet of the jet box; a jet fluid inlet pipe is arranged at the inlet end of the jet spraying nozzle and is parallel to the left clamping plate and the right clamping plate; an inlet of the jet fluid inlet pipe communicates with an outlet of the submersible pump; an air inlet pipe communicating with the outlet end of the jet spraying nozzle is arranged at the edge of the right clamping plate and communicates with an outlet of the vacuum tank; and a bolt is arranged between the left clamping plate and the right clamping plate in a penetrating mode, and the two ends of the bolt are connected with the left clamping plate and the right clamping plate in a screwed mode correspondingly and extend out of the left clamping plate and the right clamping plate correspondingly in a suspended mode. The adjustable jet vacuum pump has the advantages that the bearing pressure is high, the cleaning performance is good, and the size of the spraying nozzle is adjustable.

Description

technical field [0001] The invention relates to a negative pressure suction device, which belongs to the technical field of jet pumps for pumping fluid by utilizing the inertia of the pumped fluid. Background technique [0002] Jet vacuum pump is a device that generates, improves and maintains vacuum in a closed space by mechanical, physical, chemical or physical and chemical methods. It is generally composed of three parts: submersible pump, ejector, and pump box. It is widely used in decompression evaporation, crystallization, distillation, drying, decolorization, deodorization, vacuum transportation, etc. in petroleum, chemical, food, pharmaceutical, light industry, environmental protection and other industries.
