An energy-saving blower

Abstract

The present invention relates to the field of pneumatic blower, specifically an energy-saving blower, comprising a left protective shell, a right protective shell, an outer separation ring and a blocking plate, an outer separation ring is arranged between the left protective shell and the right protective shell, The left protective shell, the right protective shell and the outer partition ring are sequentially provided with an air inlet duct, a front pressurization chamber, a rear pressurization chamber and an exhaust air duct, and both the air intake duct and the exhaust air duct are embedded with A blocking plate is provided, and an energy-saving blower according to the present invention is provided with an inner sleeve, a meniscus, a spring and a sealing gasket in the air inlet duct and the exhaust duct, and the meniscus can be opened in one direction due to the pressure difference. When the air pressure difference does not meet the output conditions, the meniscus is reset and blocked by the action of the spring, which can not only avoid the problem of fluid backflow at the output end of the blower, but also prevent the high-pressure gas in the booster chamber from leaking out, which can keep the booster chamber In a high-voltage state, when the blower restarts, it avoids the power loss of repeated boosting, energy saving, environmental protection, safety and practicality.

Description

technical field [0001] The invention relates to the technical field of pneumatic blowers, in particular to an energy-saving blower. Background technique [0002] The blower operates eccentrically by the biased rotor in the cylinder, and makes the volume change between the blades in the rotor slot suck in, compress, and spit out the air. During operation, the pressure difference of the blower is used to automatically send the lubrication to the drip nozzle and drip into the cylinder. In order to reduce friction and noise, and at the same time keep the gas in the cylinder from flowing back, this kind of blower is also called sliding vane blower. At present, the blower has been applied to all aspects of industrial technology, such as: water aeration and oxygen supply, boiler combustion oxygen supply , natural gas liquefaction technology, etc., under the above-mentioned industrial technical conditions, there is a large pressure difference between the output end and the input end...

Problems solved by technology

[0002] The blower operates eccentrically by the biased rotor in the cylinder, and makes the volume change between the blades in the rotor slot suck in, compress, and spit out the air. During operation, the pressure difference of the blower is used to automatically send the lubrication to the drip nozzle and drip into the cylinder. In order to reduce friction and noise, and at the same time keep the gas in the cylinder from flowing back, this kind of blower is also called sliding vane blower. At present, the blower has been applied to all aspects of industrial technology, such as: water aeration and oxygen supply, boiler combustion oxygen supply , natural gas liquefaction technology, etc., under the above-mentioned industrial technical conditions, there is a large pressure difference between the output end and the input end of the blower. It is easy to flow back to the input end, which will not only cause damage to the driving equipment, but also seriously cause high-temperature gas outflow, liquid leakage or combustible gas leakage accidents, which is extremely low in safety. In addition, the inside of the blower is a gas pressurized space. , the air pressure in the gas pressurized space is raised in advance. When the blower is restarted, it needs to consume more power to increase the air pressure in the pressurized space. Therefore, there is a phenomenon of waste of electric energy. It is necessary to improve the working performance of the blower.
