Embodiment

[0018] The multi-channel jet vacuum pump of the present embodiment, as figure 1 with figure 2 As shown, a submersible pump 10 , an ejector 20 and a vacuum tank 30 are included. The jet device 20 includes a jet box 1 with an outlet. The jet box 1 is provided with a left splint 2 and a right splint 3 that fit together. The center of the left splint 2 is provided with a jet liquid inlet that passes through the left splint 2 and is perpendicular to the left splint. Pipe 4, the inlet end of the jet liquid inlet pipe 4 is connected to the outlet of the submersible pump 10 .

[0019] Between the left splint 2 and the right splint 3, a plurality of jet nozzles 5 communicated with the jet liquid inlet pipe 4 are formed, and the plurality of jet nozzles 5 are evenly distributed along the center circumference of the jet liquid inlet pipe 4, and the aperture of each jet nozzle 5 is 8-20mm, the outlet end of each jet nozzle 5 is set opposite to the outlet of the jet box 1, and the edge ...

Abstract

The invention relates to a multi-channel jet vacuum pump, and belongs to the technical field of injection pumps pumping fluid through the inertia of the fluid to be pumped. The multi-channel 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 attached to the left clamping plate are arranged in the jet box. A jet liquid inlet pipe which penetrates through the left clamping plate and is perpendicular to the left clamping plate is arranged in the center of the left clamping plate, and the inlet end of the jet liquid inlet pipe is communicated with the outlet of the submersible pump. A plurality of jet nozzles communicated with the jet liquid inlet pipe are arranged between the left clamping plate and the right clamping plate and uniformly distributed in the circumferential direction of the center of the jet liquid inlet pipe. The diameter of each jet nozzle is 8-20 mm. The outlet end of each jet nozzle is opposite to the outlet of the jet box. An air inlet pipe communicated with each jet nozzle is arranged on the edge of the right clamping plate and communicated with the outlet of the vacuum tank. The multi-channel jet vacuum pump has the advantages that the bearing pressure is large and the cleaning performance is good.

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...
