Cyclone generating device

Abstract

The invention discloses a cyclone generating device. The device comprises a material pipe, wherein the outlet end of the material pipe is arranged in a wind energy pipe, an air inlet cylinder is further arranged on the wind energy pipe, a wind energy ring and a closing ring are arranged between the positions, at the two ends of the air inlet cylinder, of the wind energy pipe and the material pipein the axial direction, the inner circle side and the outer circle side of the wind energy ring are hermetically connected with the material pipe and the wind energy pipe, the inner circle side and the outer circle side of the closing ring are hermetically connected with the material pipe and the wind energy pipe, and a plurality of air holes are further formed in the wind energy ring. After air enters from the air inlet cylinder and is discharged from the air holes through an inner cavity, a cyclone is formed at the outlet end of the wind energy pipe, so that air flow pointing to the outlet end from the inlet end is formed inside the material pipe, finally, a material at the inlet end of the material pipe moves along the material pipe under pushing of the air flow, so that material conveying is realized. The cyclone generating device can meet conveying requirements of various materials and is wide in applicability and free of blockage; and meanwhile, the cyclone generating device is simple in structure, low in manufacturing cost, stable in working and long in service life.

Description

technical field [0001] The invention relates to a conveying device, in particular to a cyclone generating device which drives material movement or gas suction by generating a cyclone and forming a negative pressure. Background technique [0002] The transportation of materials can be seen everywhere in industrial production or people's daily life. The transportation of large solid materials generally includes manual or robotic handling, conveyor belt transportation, etc.; for liquid transportation, pumps and centrifugal pumps are usually used. Cooperate with pipelines for transportation; in addition, for small solid debris, suspended solids, etc., they can be extracted and collected by suction devices such as vacuum cleaners.

Problems solved by technology

[0003] Among them, the centrifugal pump is a mechanical device that transports liquid by the centrifugal force generated when the impeller rotates. The impeller of this kind of centrifugal pump will rotate violently during the working process, and the impeller must meet the specific requirements of the curved sheet shape. At the same time, In order to prevent liquid or suspended matter from corroding, abrading or even winding the moving parts of the impeller assembly, the centrifugal pump has very high requirements on the chemical corrosion and suspended matter content of the transported liquid, which makes it only suitable for clean water, or similar On the other hand, centrifugal pumps use atmospheric pressure to pump liquids, which cannot transport liquids whose liquid level is lower than the height of the pump head of the centrifugal pump, which greatly limits ability to transport liquids

[0004] The air extraction device generally includes an air extraction pipe and a fan that forms a gas flow in the air extraction pipe. The air inlet of the fan faces the inlet end of the air extraction pipe. In order to prevent solid debris or suspended matter from entering the fan and causing the fan to fail, a The tuyere must be equipped with a filter, but even so, it is still difficult to completely isolate the entry of solid debris or suspended matter, and as the fan works, solid debris or suspended matter will continue to accumulate at the fan inlet. After working for a certain period of time, it is necessary to clean up the accumulation at the air inlet of the fan; on the other hand, the existence of the fan and the filter will inevitably hinder the airflow and form a wind resistance, which will cause adverse effects on the suction efficiency of the air extraction device. In addition, some air extraction devices with higher requirements need to add a filter recoil subsystem composed of an air compressor and a complex pulse control circuit to ensure the smooth progress of the air extraction work, but this will Greatly increases the complexity of the equipment structure, and increases the production and maintenance costs of the equipment
