Description

Technical Field

[0001] The utility model relates to the technical field of equipment for driving gas flow, in particular to a dust removal and purification fan. Background Technique

[0002] A dust removal and purification fan is a fan device specifically used to remove dust and pollutants in the air to achieve air purification.

[0003] Equipped with strong suction and wind power, it can quickly and effectively capture and suck away dust particles in the air. Through special air duct design and impeller structure, the efficiency and effect of dust removal are improved.

[0004] When the dust removal and purification fan is in use, dust will enter the fan and accumulate inside. After the fan has been used for a long time, the amount of dust accumulated inside the fan is too large, the internal space of the fan becomes smaller, affecting the air guiding effect generated by the rotation of the blades inside the fan, and there is room for improvement. Content of the Utility Model

[0005] The purpose of the utility model is to provide a dust removal and purification fan to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A dust removal and purification fan, including a base, a protective cover is fixedly installed on the base, an air guiding cover is coaxially fixedly installed on one side of the air inlet of the protective cover, a dust blocking net is fixedly installed on one side of the inner wall of the air guiding cover close to the protective cover, a central connecting ball is fixedly installed at the central position of the dust blocking net, multiple connecting ropes are fixedly installed on the central connecting ball, a knot is fixedly installed at the end of the connecting rope, a through hole corresponding to the connecting rope is opened on one side of the air guiding cover away from the protective cover, a rope winding buckle is fixedly installed in the through hole, one end of the connecting rope away from the central connecting ball is located in the rope winding buckle, and the knot also passes through the rope winding buckle.

[0007] Preferably, the multiple connecting ropes are arranged in a circular array centered on the central connecting ball.

[0008] Preferably, the knot and the connecting rope are located on both sides of the rope winding buckle.

[0009] Preferably, an annular conduit is fixedly installed on the central connecting ball.

[0010] Preferably, the central connecting ball and the outer side of the air guiding cover are on the same vertical plane, and the part of the dust blocking net installed on the air guiding cover and the inner side of the air guiding cover are on the same vertical plane.

[0011] Preferably, an annular conduit is provided outside the air draft hood. A connecting pipe is provided between the annular conduit and the dust baffle net for connection, and the connecting pipe penetrates through the air draft hood. A water tank is provided on one side of the protective cover close to the air draft hood. A liquid delivery pipe is provided at the water outlet end of the water tank. The liquid delivery pipe is communicated with the annular conduit. A regulating valve is provided on the liquid delivery pipe. A U-shaped hanging buckle is provided at the end of the connecting pipe, and the dust baffle net is connected to the annular conduit through the connecting pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] By adjusting the installation position of the end of the connecting rope on the rope winding buckle, the tension applied by the connecting rope to the central connecting ball is changed. When the central connecting ball is subjected to a large tension, the deformation amplitude of the dust baffle net is large; when the central connecting ball is subjected to a small tension, the deformation amplitude of the dust baffle net is small. The deformation of the dust baffle net changes the area of the dust baffle net, making it better in contact with the air. The air containing dust and debris contacts the dust baffle net, and the dust baffle net adsorbs the impurities in the air. When too many air impurities are adsorbed on the dust baffle net, the annular conduit is pulled to vibrate the dust baffle net, thereby realizing the cleaning of the dust on the dust baffle net. Through the dust baffle net that can automatically suck dust, dust entering the internal part of the induced draft fan can be effectively blocked, the wear and erosion of key components such as the impeller and the motor by dust are reduced, and their service life is prolonged.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a dust removal and purification fan, including a base 1, a protective cover 2 is fixedly installed on the base 1, an air guide cover 3 is coaxially and fixedly installed on one side of the air inlet of the protective cover 2, the air guide cover 3 is a conical cylinder structure, which can better suck the outside air into the protective cover 2 and assist the flow of air in the protective cover 2. A dust blocking net 4 is fixedly installed on one side of the inner wall of the air guide cover 3 close to the protective cover 2. The dust blocking net 4 is woven by elastic metal wires and is circular. When the dust blocking net 4 is pressed, the dust blocking net 4 vibrates, so as to ensure the detachment of dust on the dust blocking net 4. At the same time, the dust detached from the dust blocking net 4 can also fall along the air guide cover 3. A central connecting ball 5 is fixedly installed at the central position of the dust blocking net 4. Pulling the central connecting ball 5 drives the deformation of the dust blocking net 4. After the deformation of the dust blocking net 4, it is a conical mesh structure. A plurality of connecting ropes 6 are fixedly installed on the central connecting ball 5. The plurality of connecting ropes 6 fix the central connecting ball 5 to ensure the pulling effect of the central connecting ball 5 on the dust blocking net 4. A knot 7 is fixedly installed at the end of the connecting rope 6. The knot 7 is used for fixing the end of the connecting rope 6 to ensure the stability of the installation of the connecting rope 6. An air guide cover hole 31 is opened at the position of the air guide cover 3 away from the protective cover 2 corresponding to the connecting rope 6. A rope winding buckle 8 is fixedly installed in the air guide cover hole 31. The rope winding buckle 8 is used for the installation of the connecting rope 6 and fixes the end of the connecting rope 6 through the knot 7. One end of the connecting rope 6 away from the central connecting ball 5 is located in the rope winding buckle 8, and the knot 7 also passes through the rope winding buckle 8.

[0022] The plurality of connecting ropes 6 are arranged in a circular array with the central connecting ball 5 as the center. Select the corresponding number of connecting ropes 6 according to needs to ensure that the plurality of connecting ropes 6 can fix the central connecting ball 5 and improve the fixing effect of the central connecting ball 5.

[0023] The knot 7 and the connecting rope 6 are located on both sides of the rope winding buckle 8 to ensure the limit of one end of the connecting rope 6 by the knot 7. The position of the knot 7 on the rope winding buckle 8 can be adjusted to realize the adjustment of the position of the central connecting ball 5.

[0024] An annular conduit 9 is fixedly installed on the central connecting ball 5. The existence of the annular conduit 9 assists in pulling the central connecting ball 5, facilitates the movement of the central connecting ball 5, and improves the convenience of moving the central connecting ball 5.

[0025] The outer side of the central connecting ball 5 and the air guiding cover 3 is located on the same vertical plane, and the part of the dust blocking net 4 installed on the air guiding cover 3 and the inner side of the air guiding cover 3 are located on the same vertical plane, ensuring that the dust blocking net 4 can form a conical structure.

[0026] An annular conduit 9 is arranged outside the air guiding cover 3. A connecting pipe 10 is arranged between the annular conduit 9 and the dust blocking net 4 for connection, and the connecting pipe 10 penetrates through the air guiding cover 3. A water tank 11 is arranged on the side of the protective cover 2 close to the air guiding cover 3. A liquid delivery pipe 12 is arranged at the water outlet end of the water tank 11. The liquid delivery pipe 12 is communicated with the annular conduit 9. A regulating valve 13 is arranged on the liquid delivery pipe 12. The discharge of water from the water tank 11 is controlled through the regulating valve 13. The water in the water tank 11 enters the annular conduit 9 through the liquid delivery pipe 12, and then enters the dust blocking net 4 through the connecting pipe 10 to wet the dust blocking net 4, ensuring the adsorption effect of the dust blocking net 4 on dust debris. A U-shaped hanging buckle 14 is arranged at the end of the connecting pipe 10, and the dust blocking net 4 is connected to the annular conduit 9 through the connecting pipe 10. Through the U-shaped hanging buckle 14 at the end of the connecting pipe 10, it is ensured that the U-shaped hanging buckle 14 can be connected to the dust blocking net 4, thereby realizing the reinforcement of the connecting pipe 10 to the dust blocking net 4.

[0027] Working principle:

[0028] By adjusting the installation position of the end of the connecting rope 6 on the rope winding buckle 8, the tightness of the connecting rope 6 is adjusted, thereby changing the pulling force exerted by the connecting rope 6 on the central connecting ball 5. When the central connecting ball 5 is subjected to a large pulling force, the deformation amplitude of the dust blocking net 4 is large; when the central connecting ball 5 is subjected to a small pulling force, the deformation amplitude of the dust blocking net 4 is small. The deformation of the dust blocking net 4 changes the area of the dust blocking net 4, making it better contact with the air. Turn the regulating valve 13 so that the water in the water tank 11 can flow. The water in the water tank 11 flows along the liquid delivery pipe 12 and enters the annular conduit 9, and then enters the dust blocking net 4 through the connecting pipe 10 and adheres to the dust blocking net 4. The blades in the protective cover 2 rotate, and the air is guided through the air guiding cover 3 into the protective cover 2. The air containing dust debris contacts the dust blocking net 4, and the dust blocking net 4 adsorbs the impurities in the air. When too many air impurities are adsorbed on the dust blocking net 4, the annular conduit 9 is pulled to exert pressure on the central connecting ball 5. After the central connecting ball 5 is pressed, it pulls the dust blocking net 4 to vibrate, thereby realizing the cleaning of the dust on the dust blocking net 4.
