Description

TECHNICAL FIELD

[0001] The application relates to the field of centrifugal fans, in particular to an energy-saving and environment-friendly centrifugal fan convenient to clean. BACKGROUND

[0002] The centrifugal fan is widely used in many fields. In tobacco production, the centrifugal fan is used to discharge the humid gas in a roller, and the gas contains a mixture of tobacco and sugar, which adheres to the impeller and affects the operation of the impeller. Therefore, the centrifugal fan needs to be cleaned regularly.

[0003] Patent No. CN211144931U discloses a self-cleaning centrifugal fan, which comprises a volute, a motor and an impeller arranged in the volute. The volute is characterized in that a spray pipe is arranged in the volute, the spray pipe comprises a spray section and a nozzle section, the spray section is provided with small holes, and the spray section is arranged above the impeller. The nozzle section penetrates the volute, and the water outlet of the nozzle section is located at the air inlet of the fan. The bottom of the volute is connected with a drain pipe. The patent can wash the impeller by spraying water into the spray pipe and then spraying the water into the volute. However, the water washing is not enough to clean the stubborn stains on the volute and the impeller. If the impeller is started to rotate and wash, the impeller will splash the sewage out of the volute, which will pollute the environment. CONTENT OF THE UTILITY MODEL

[0004] In order to facilitate the washing of the volute and the impeller, the application provides an energy-saving and environment-friendly centrifugal fan convenient to clean.

[0005] The energy-saving and environment-friendly centrifugal fan convenient to clean provided by the application adopts the following technical scheme:

[0010] The cleaning device comprises a water tank fixed to the fan body, a water pump installed in the water tank, a nozzle installed in the top end of the fan body, and a rotating assembly connected to the nozzle and the water pump respectively. The nozzle is a multi-angle nozzle. The upper end of the water tank is provided with a water inlet pipe, and the rotating assembly is used to drive the nozzle to rotate and spray.

[0011] By adopting the technical scheme, when the fan body needs to be flushed, water in the water tank is introduced into the rotating assembly by the water pump, the water drives the rotating assembly to rotate when passing through the rotating assembly, thereby driving the spray head to rotate and spray, the spraying range is increased, and the volute and the blade are flushed, so that the cleaning effect is ensured.

[0012] In a possible implementation, the rotating assembly comprises:

[0013] The connecting pipe is inserted into the water tank at one end and connected with the water pump, and is inserted into the fan body at the other end;

[0022] In a possible implementation, the quantity control mechanism comprises:

[0023] The first feeding cylinder is fixedly arranged on the second supporting frame and connected with the liquid inlet pipe;

[0024] The second feeding cylinder is rotatably arranged on the second supporting frame;

[0025] A driving component is mounted on the second feed cylinder and connected to a motor drive for driving the second feed cylinder to rotate relative to the first feed cylinder.

[0026] The first feed cylinder has a first feed port, and the second feed cylinder has a second feed port. The first feed port and the second feed port are staggered. When the second feed cylinder rotates, the second feed port will intermittently overlap with the first feed port.

[0034] In summary, this application includes the following beneficial technical effects: When the blower body needs to be flushed, the water pump introduces water into the connecting pipe, and the water enters the first turntable through the connecting pipe, driving the blades in the first turntable to rotate. Simultaneously, the rotation of the blades drives the rotating rod to rotate, which in turn drives the second turntable to rotate, thus rotating the nozzle. At the same time, as the blades rotate, water flows through the through-hole into the second turntable and then enters the nozzle for spraying, thereby increasing the spray range and flushing the volute and blades, ensuring a cleaning effect. The cleaning fluid is poured into the second feed cylinder, and the rotation of the shaft drives the first gear. The first, second, and third gears mesh, causing the second feed cylinder to rotate relative to the first feed cylinder. This causes the first and second feed inlets to intermittently overlap, and the cleaning fluid is then introduced into the inlet pipe and water tank through the first feed inlet, achieving a flow control effect. The water tank is then stirred by the stirring rod to improve the mixing of the cleaning fluid and water. Attached Figure Description
