Description
Technical Field
[0001] This utility model relates to the technical field of energy-saving fans, and in particular to an energy-saving fan specifically designed for dust treatment and purification. Background Technology
[0002] Dust generation is unavoidable in industrial production processes, especially in industries such as mining, metallurgy, chemicals, and building materials. Dust not only pollutes the production environment but also poses a threat to the health of operators. Therefore, the collection and purification of dust is of paramount importance. Currently, commonly used dust treatment equipment is typically equipped with fans to extract dust-laden gases and deliver them to the purification system.
[0003] A related technology, CN212068144U, discloses an energy-saving fan for dust treatment and purification, comprising a movable box. The movable box has partitions fixedly connected to its inner cavity, and a movable plate is positioned between the two partitions. An electric push rod is fixedly connected to the top of the movable plate, with the end of the electric push rod away from the movable plate fixedly connected to the movable box. First sliders are fixedly connected to both sides of the movable plate. A first sliding groove is formed on one side of the partition to cooperate with the first sliders, and the first sliders are slidably connected to the first sliding groove. This invention, through the coordinated use of the movable box, partitions, movable plate, electric push rod, first sliders, first sliding groove, support legs, rollers, and through-slots, has the advantage of easy movement. It solves the problem that existing energy-saving fans are difficult to move, increasing the difficulty for operators to move them to the desired location, resulting in time and effort wasted and inconvenient for users.
[0004] Due to their inherent design characteristics, the dust treatment and purification fans mentioned above are not suitable for filtering the gas entering the fan, which easily leads to dust accumulation inside the fan, affecting its normal operation. Furthermore, during operation, these accumulated dust and impurities can cause wear and tear on internal components, increase the failure rate, and even cause the fan to jam or become blocked, affecting its working efficiency and even shortening its service life. Utility Model Content
[0005] This invention solves the problems in related technologies and proposes a dedicated energy-saving fan for dust treatment and purification. When the fan is operating, dusty gas enters the dust collection chamber through the inlet, and then passes through a dust filter unit for filtration, effectively preventing dust from entering the fan body. The filtered clean gas then enters the fan body's inlet through the outlet, ensuring that the fan body is not contaminated by dust. Simultaneously, the dust filter unit has a built-in dust removal component that can remove dust during the filtration process in real time, preventing dust adhesion from affecting the filtration effect, thus ensuring the overall high efficiency of the system.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a dust treatment and purification energy-saving fan, including a fixed bracket, a fan body fixedly connected to the fixed bracket, an air inlet connected to one end of the fan body, an air outlet located at the other end of the fan body, a dust collection box connected to the air inlet of the fan body, an exhaust port located on the dust collection box relative to the air inlet, an air inlet located on the upper surface of the other side of the dust collection box, a dust filter unit located in the inner cavity of the dust collection box, a guide plate located on the lower surface of the dust filter unit, and a waste collection box located on the lower surface of the guide plate and slidably connected to the dust collection box. The dust filtration unit includes a filter assembly disposed in the inner cavity of the dust collection box and a dust removal assembly for cleaning impurities adhering to the filter assembly.
[0007] By adopting the above technical solution, when the fan body is working, dusty gas enters the inner cavity of the dust collection box through the air inlet, and then passes through the dust filter unit for filtration, effectively blocking dust from entering the fan body. The filtered clean gas enters the air inlet of the fan body through the exhaust port, ensuring that the fan body is not contaminated by dust. At the same time, the dust filter unit has a built-in dust removal component that can remove dust in real time during the filtration process, preventing dust adhesion from affecting the filtration effect, thereby ensuring the efficient operation of the entire system. The working principle and process can be summarized as follows: First, dusty gas enters through the air inlet, and after preliminary filtration by the filter unit, clean gas is discharged. The dust in the filtration process is cleaned in time by the dust removal component to maintain the optimal filtration state of the filter unit, ultimately achieving the purpose of effectively blocking dust from entering the fan, protecting the fan, and improving system efficiency.
[0008] As a preferred embodiment, the discharge port and the air inlet are connected by a connecting flange, and a sealing gasket is provided at the connection point.
[0009] By adopting the above technical solution, the filtered gas can be easily drawn into the fan body through the air inlet by the negative pressure of the fan body through the exhaust port.
[0010] As a preferred embodiment, the filter assembly includes a plurality of hollow filter cylinders disposed in the upper part of the inner cavity of the dust collection box, a first mounting frame disposed on the upper end face of the filter cylinders, and a second mounting frame disposed on the lower end face of the filter cylinders, wherein the outer peripheries of the first mounting frame and the second mounting frame are respectively fixedly connected to the inner cavity of the dust collection box.
[0011] By adopting the above technical solution, it is convenient to support the filter cylinder through the first mounting frame and the second mounting frame.
[0012] As a preferred embodiment, each of the filter cylinders extends through the first mounting frame and overlaps with the second mounting frame, and each filter cylinder is composed of multiple layers of filter screens.
[0013] By adopting the above technical solution, several filter cylinders are installed in the upper part of the dust collection box. Each filter cylinder is composed of multiple layers of filter screens. By installing a first mounting frame on the upper end face of the filter cylinder and a second mounting frame on the lower end face, and fixing these mounting frames to the inner cavity of the dust collection box, the filter cylinder can be effectively supported and its stable operation can be ensured.
[0014] As a preferred embodiment, the dust removal assembly includes an acoustic reflector disposed relative to the upper end face of each of the filter cylinders, a waveguide for connecting the acoustic reflectors, an acoustic wave delivery pipe connected to the waveguide, and an acoustic wave generator connected to the acoustic wave delivery pipe.
[0015] As a preferred embodiment, the acoustic wave conveying pipe passes through the dust collection box and connects to the acoustic wave generator, and an installation bracket is provided between the acoustic wave generator and the dust collection box, and the installation bracket is fixedly connected to the dust collection box.
[0016] By adopting the above technical solution, the mounting bracket facilitates the installation of the sound wave generator.
[0017] As a preferred embodiment, one end of the waveguide is connected to the acoustic wave transmission pipe, and the other end of the waveguide is fixedly connected to the inner cavity of the dust collection box.
[0018] By adopting the above technical solution, the waveguide is used to divert sound waves to each connected sound wave emitting hood. Through the sound wave reflector located on the upper surface of each filter cartridge, and the waveguide and sound wave delivery pipes connecting them, the low-frequency, high-energy sound waves (frequency range 50Hz to 200Hz, sound pressure level range 140dB to 160dB) generated by the sound wave generator are introduced into the filter cartridge. The mounting bracket is fixed to the dust collection box, facilitating the installation of the sound wave generator. The sound waves are amplified when passing through the sound wave emitting hood, effectively removing accumulated dust from the dust collection plate inside the filter cartridge. Simultaneously, the sound wave energy does not damage the equipment, resulting in a significant and efficient dust removal effect. The waveguide evenly distributes the sound wave energy to each filter cartridge, achieving a comprehensive dust removal effect and enhancing the service life and filtration efficiency of the filter cartridge. As a preferred embodiment, the guide plate is fixedly disposed on the lower end face of the second mounting frame, and the inner cavity of the guide plate decreases sequentially from the end furthest from the second mounting frame.
[0019] By adopting the above technical solution, this design facilitates the dust falling through the second dust removal component to enter the waste collection box along the inner cavity of the guide plate.

[0030] In one embodiment, please refer to [specific example]. Figure 1 , Figure 2 , Figure 3 and Figure 4The dust filtration unit includes a filter assembly disposed within the inner cavity of the dust collection box 3 and a cleaning assembly for cleaning impurities adhering to the filter assembly. The filter assembly includes several hollow filter cylinders 5 disposed in the upper part of the inner cavity of the dust collection box 3, a first mounting frame 51 disposed on the upper end face of the filter cylinder 5, and a second mounting frame 52 disposed on the lower end face of the filter cylinder 5. The outer peripheries of the first mounting frame 51 and the second mounting frame 52 are respectively fixedly connected to the inner cavity of the dust collection box 3, facilitating the passage of impurities. The filter cylinder 5 is supported by a frame 52. Each filter cylinder 5 passes through the first mounting frame 51 and overlaps with the second mounting frame 52. Each filter cylinder 5 is composed of multiple layers of filter screens. Several filter cylinders 5 are installed in the upper part of the inner cavity of the dust collection box 3. Each filter cylinder 5 is composed of multiple layers of filter screens. By installing the first mounting frame 51 on the upper end face and the second mounting frame 52 on the lower end face of the filter cylinder 5, and fixing these mounting frames to the inner cavity of the dust collection box 3, the filter cylinder 5 can be effectively supported and its stable operation can be ensured. When the gas containing dust enters the inner cavity of the dust collection box 3, it will first pass through the multiple layers of filter screens of the filter cylinder 5, and can be gradually filtered and purified to remove dust particles, thereby achieving effective purification of the gas and thus effective collection and treatment of dust.
[0031] In one embodiment, please refer to [specific example]. Figure 3 and Figure 4The dust removal assembly includes an acoustic reflector 631 disposed on the upper end face of each filter cylinder 5, a waveguide 63 connecting the acoustic reflectors 631, an acoustic delivery pipe 62 connected to the waveguide 63, and an acoustic generator 61 connected to the acoustic delivery pipe 62. The acoustic delivery pipe 62 passes through the dust collection box 3 and is connected to the acoustic generator 61. A mounting bracket 4 is provided between the acoustic generator 61 and the dust collection box 3. The mounting bracket 4 is fixedly connected to the dust collection box 3, and the mounting bracket 4 facilitates the mounting of the acoustic generator 61. The waveguide 63 is installed with one end connected to the acoustic wave delivery pipe 62 and the other end fixedly connected to the inner cavity of the dust collection box 3. The waveguide 63 is used to divert acoustic waves to each connected acoustic wave emitting hood. Through the acoustic wave reflector 631 located on the upper surface of each filter cylinder 5 and the waveguide 63 and acoustic wave delivery pipe 62 connecting them, the low-frequency, high-energy acoustic waves (frequency range 50Hz to 200Hz, sound pressure level range 140dB to 160dB) generated by the acoustic wave generator 61 are introduced into the filter cylinder 5. The mounting bracket 4 is fixed to the dust collection box 3 to facilitate the installation of the acoustic wave generator 61. The acoustic waves are amplified when passing through the acoustic wave emitting hood, effectively removing accumulated dust from the dust collection plate inside the filter cylinder 5. Simultaneously, the acoustic wave energy does not damage the equipment, resulting in a significant and efficient dust removal effect. The sound wave energy is evenly distributed into each filter cartridge 5 by the waveguide 63, achieving a comprehensive dust removal effect and enhancing the service life and filtration efficiency of the filter cartridge 5. In one embodiment, please refer to [specific example]. Figure 2 The guide plate 7 is fixedly installed on the lower end face of the second mounting frame 52, and the inner cavity of the guide plate 7 decreases sequentially from the end away from the second mounting frame 52. This design facilitates the dust falling through the second dust removal component to enter the waste collection box 8 along the inner cavity of the guide plate 7.
[0032] In this embodiment, during operation, when the fan body 2 is working, dusty gas enters the inner cavity of the dust collection box 3 through the air inlet 31. When the dust-containing gas enters the inner cavity of the dust collection box 3, it first passes through the multi-layer filter screen of the filter cylinder 5, where it is gradually filtered and purified, removing dust particles and achieving effective purification of the gas. This, in turn, achieves effective collection and treatment of dust. The sound wave generator 61 generates low-frequency, high-energy sound waves with a frequency range of 50Hz to 200Hz and a sound pressure level range of 140dB to 160dB. These sound waves are transported to the dust collection box 3 through the sound wave conveying pipe 62, and then transmitted to the waveguide 63 through the mounting bracket 4. The waveguide 63 evenly distributes the sound waves to each sound wave reflector 631 located on the upper surface of the filter cylinder 5. The sound wave reflectors 631 further enhance the propagation effect of these sound waves within the inner cavity of the filter cylinder 5. Ultimately, this sound wave energy effectively removes the accumulated dust on the filter cylinder 5, and the filtered clean gas enters the air inlet 21 of the fan body 2 through the exhaust port 32, ensuring that the fan body 2 is not contaminated by dust.
[0033] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
