Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal fans, in particular to an environmentally friendly dust removal and explosion-proof centrifugal fan. Background Art

[0002] The main functions of centrifugal fans include ventilation, cooling and dust removal. Centrifugal fans are widely used in factories, workshops, warehouses and other places to promote air circulation, ensure fresh air, and are conducive to the preservation of mechanical equipment or industrial products. Centrifugal fans are used in mines and tunnels to help improve air circulation and remove polluted air in time. Centrifugal fans are used in agricultural processing, food processing and other fields to promote the drying and selection of materials such as grains and wheat. Centrifugal fans are used in industrial boilers, gas furnaces, and coal-fired furnaces to supply oxygen-rich air, improve the production and working environment, and remove harmful gases.

[0003] In the prior art, a centrifugal fan is mainly composed of an impeller, a casing, a coupling, and a shaft. The impeller is the main working component for generating wind pressure and transmitting energy. It is mainly used to introduce and exhaust gas, and at the same time convert part of the kinetic energy of the gas into pressure energy, and compress the gas and send it out of the fan to achieve ventilation effect.

[0004] However, the working environment of centrifugal fans is generally dusty or smoky. The dust or smoke is discharged through the fan. Working in this environment for a long time will cause the internal parts of the centrifugal fan to be covered with dust, making the centrifugal fan prone to malfunction during use and causing damage to the centrifugal fan. In addition, a filter is installed behind the air inlet of the centrifugal fan. After long-term use, dust will accumulate on the surface of the filter, affecting the air intake and dust exhaust of the centrifugal fan.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the prior art has dust or smoke that makes the centrifugal fan prone to malfunction during use, resulting in damage to the centrifugal fan, and a filter is installed behind the air inlet of the centrifugal fan. After long-term use, dust will accumulate on the surface of the filter, affecting the deficiencies and defects of the centrifugal fan in air intake and dust exhaust.

[0007] The utility model discloses an environmentally friendly dust-removing and explosion-proof centrifugal fan, comprising a dust removal box, the inner wall of the dust removal box is fixedly connected to a support frame, the outer surface of the support frame is rotatably connected to a rotating rod, the outer surface of the rotating rod is fixedly connected to a rotating ring, the outer surface of the rotating ring is fixedly connected to teeth arranged at equal distances, the inner bottom wall of the dust removal box is fixedly connected to a motor 1, the output end of the motor 1 is fixedly connected to a gear, the outer surface of the gear is meshed with the outer surface of the corresponding tooth, the end of the rotating rod away from the support frame is fixedly connected to a cleaning brush, and the outer surface of the cleaning brush is in contact with a filter.

[0008] Furthermore, the outer surface of the filter is fixedly mounted to the inner wall of the dust removal box, the bottom surface of the dust removal box is provided with an ash drop opening, and a dust collecting water tank is provided below the ash drop opening.

[0009] Furthermore, a fixing plate is fixedly connected to the back of the dust removal box, a sliding groove is opened on the inner wall of the fixing plate, a sliding block is slidably connected to the inner wall of the sliding groove, and the front side of the sliding block is fixedly connected to the back of the dust collecting water tank.

[0010] Furthermore, a limiting groove is provided on the back side of the sliding block, and a locking piece is slidably contacted on the inner wall of the limiting groove.

[0011] Furthermore, the outer surface of the locking piece is slidably connected to the inside of the fixing plate, the front side of the locking piece is fixedly connected to two springs, and one end of each spring away from the locking piece is fixedly connected to the back side of the fixing plate.

[0012] Furthermore, a fan is fixedly connected to the back of the dust removal box, a second motor is fixedly installed on the outer surface of the fan, and an impeller is fixedly connected to the output end of the second motor.

[0013] Furthermore, two fixing rings are fixedly connected to the inner wall of the fan, the inner wall of each fixing ring is rotatably connected to a limiting ring, and the side surfaces of each limiting ring close to each other are fixedly connected to the front and back surfaces of the impeller.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model is provided with a rotating ring, a gear, a rotating rod and other components. The motor drives the gear to rotate and mesh with the teeth to rotate the rotating ring. At the same time, the rotating ring drives the rotating rod to rotate and drives the cleaning brush to rotate. The cleaning brush contacts the filter to clean the dust attached to the outer surface of the filter. At the same time, the dust removed by the cleaning brush falls into the dust outlet and enters the dust collecting water tank, so that the device can prevent dust from damaging the fan and automatically clean the filter.

[0016] 2. The utility model provides a fixed plate, a sliding block, a dust collecting water tank, a locking piece and other components. The sliding block is driven by the dust collecting water tank to enter the sliding groove provided in the fixed plate. When the sliding block slides in the sliding groove, the sliding block contacts the locking piece and pushes the locking piece open and stretches the spring until the sliding block reaches the end of the sliding groove. At the same time, the spring rebounds and drives the locking piece to enter the limiting groove to lock the position of the sliding block. At the same time, the dust collecting water tank is aligned with the dust falling port to make the filter fall into the dust collecting water tank. Conversely, the position lock of the sliding block is released by pulling the locking piece to drive the spring to stretch and the dust collecting water tank is pulled out, thereby achieving the effect of facilitating the installation and disassembly of the dust collecting water tank and preventing secondary dusting.
