Backward-tilting multi-wing anti-explosion centrifugal fan

Abstract

The invention discloses a backward-tilting multi-wing anti-explosion centrifugal fan. The backward-tilting multi-wing anti-explosion centrifugal fan comprises a fan shell and a socket. A protection ring is fixedly arranged on the outer surface of the front end of the fan shell, and a fixing ring is arranged at the bottom end of the protection ring. An aluminum alloy impeller is arranged at the bottom end of the fixing ring, and an air outlet pipe is arranged on one side of the fan shell. The backward-tilting multi-wing anti-explosion centrifugal fan is provided with the socket, a bolt, a static dust suction plate, a sound absorbing plate and an inner container, a motor can be rapidly dismounted and replaced, and the motor can be more conveniently dismounted and repaired; cooling and explosion prevention can be conducted by replacing a rotation shaft in the motor, and the motor can better work; air entering the motor can be subjected to dust removal, a certain influence on the motor from dust can be prevented, and the motor can be better used and work; and noise generated by the motor can be absorbed, corrosion prevention can be further conducted on the inner container, and better usage prospects are brought.

Description

technical field [0001] The invention relates to the field of centrifugal fans, in particular to a backward inclined multi-wing explosion-proof centrifugal fan. Background technique [0002] The centrifugal fan is mainly composed of: impeller, casing, coupling, shaft. The impeller is the main working part that generates wind pressure and transmits energy. The casing is mainly used to introduce gas and discharge gas, and at the same time convert part of the kinetic energy of the gas into pressure energy. The coupling is used to connect the motor and fan to transmit torque. The shaft is installed And fix the impeller, through the coupling and the motor; the existing backward multi-blade explosion-proof centrifugal fan has certain disadvantages in use. First, the motor cannot be disassembled and repaired in time, and the existing motor cannot be disassembled quickly. , which has a certain impact on repairs. Secondly, it is impossible to remove dust from the gas entering the cen...

Problems solved by technology

The impeller is the main working part that generates wind pressure and transmits energy. The casing is mainly used to introduce gas and discharge gas, and at the same time convert part of the kinetic energy of the gas into pressure energy. The coupling is used to connect the motor and fan to transmit torque. The shaft is installed And fix the impeller, through the coupling and the motor; the existing backward multi-blade explosion-proof centrifugal fan has certain disadvantages in use. First, the motor cannot be disassembled and repaired in time, and the existing motor cannot be disassembled quickly. , which has a certain impact on repairs. Secondly, it is impossible to remove dust from the gas entering the centrifugal fan, causing dust to enter the motor and affect the normal operation of the motor. Finally, it is impossible to further prevent explosion by setting the inner tank, and it is not possible to protect the motor when it is working. The noise generated during the process is processed, which has a certain impact on people's use process. Therefore, we propose a backward multi-blade explosion-proof centrifugal fan
