Abstract

The invention relates to a jet device with a plurality of parallel channels and belongs to the technical field of injection pumps utilizing the inertia of pumped fluid for pumping the fluid. The jet device with the parallel channels comprises a jet box with an outlet. A left clamping plate and a right clamping plate are mutually attached and arranged in the jet box. A plurality of parallel jet nozzles are formed between the left clamping plate and the right clamping plate. The inlet end of each jet nozzle is provided with a jet liquid inlet pipe. The jet liquid inlet pipes are parallel to the left clamping plate and the right clamping plate. Inlets of the jet liquid inlet pipes are communicated with the exterior of the jet box. The bore diameter of each jet nozzle is 8 mm-20 mm. The outlet ends of the jet nozzles are arranged opposite to an outlet of the jet box. The edge of the right clamping plate is provided with an air inlet pipe communicated with all the jet nozzles. The jet device with the parallel channels has the advantages of being high in bearing pressure and good in cleaning performance.

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. In the process. [0003] For the nozzles in the existing ejector, if the nozzles are clogged, use a soft brush or toothpick to clean it and be very careful during the cleaning process, which may distort the orifice. In addition, the existing nozzles have low bear...
