Description

Technical Field

[0001] The invention belongs to the technical field of fans, and in particular relates to an energy-saving electrolytic aluminum fan. Background Art

[0002] When the flow area of ​​any link of the oxidation fan inlet and outlet is reduced, the local flow rate will be too high, the overall resistance will increase, and the fan efficiency will be affected. After the filter located in the air inlet duct has been running for a period of time, the dust in the environment will be adsorbed, the co-flow area will decrease, the total resistance that the fan needs to overcome will increase, and the operating efficiency will decrease. In order to ensure that the fan is in the best operating point of the design selection, the filter needs to be cleaned frequently, mainly by manual or motor-driven scraper cleaning, which has the disadvantages of time-consuming, labor-intensive and increased power consumption.

[0003] The existing filter screen located in the air inlet pipe of the oxidation fan will absorb dust after the fan has been used for a period of time. As the dust accumulates, the diameter of the ventilation holes on the filter screen will decrease, increasing the resistance loss of the pipe system and reducing the efficiency of the fan. There are two existing methods for cleaning the filter screen: 1) disassembling the filter screen and cleaning it manually, which is convenient and easy to operate, but requires downtime for processing, which is time-consuming and labor-intensive; 2) setting a scraper driven by a motor at the air inlet end of the filter screen, and removing the dust on the filter screen through the rotation of the scraper, which saves time and labor, and does not require downtime for cleaning, but requires the installation of an additional motor, which increases the consumption of electricity and is not conducive to energy saving.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present application provides an energy-saving electrolytic aluminum fan, referring to Figure 1 , comprising a housing 1, an air inlet pipe 2 is installed at one end of the housing 1 and communicated with the air inlet pipe 2, a driver 5 is installed at the end of the housing 1 away from the air inlet pipe 2; an air outlet pipe 3 is installed on the outer wall of the housing 1 and communicated with the air outlet pipe 3; an impeller 4 is installed inside the housing 1, reference Figure 2 The output end of the driver 5 is fixedly connected to the first impeller 4; a filter screen 21 is installed inside the air inlet pipe 2; a cleaning component 6 is installed at the end of the air inlet pipe 2 away from the housing 1 at the filter screen 21; an energy storage component 7 is provided on the inner wall of the housing 1; the energy storage component 7 is used to drive the cleaning component 6 to clean the filter screen 21.

[0032] During the implementation process, the driver 5 adopts a variable frequency motor, which can adjust the motor speed by changing the power supply frequency. In the electrolytic aluminum oxidation fan, the use of a variable frequency motor can achieve more precise speed control and air volume adjustment, thereby improving operating efficiency and energy saving. At the same time, the variable frequency motor also has a soft start function, which can reduce the impact of the starting current on the power grid and extend the service life of the motor; during normal operation of the fan, the driver 5 drives the No. 1 impeller 4 to rotate, generating suction on the air inlet pipe 2, so that the air outside the shell 1 enters the inside of the shell 1 through the air inlet pipe 2, and the air is preliminarily filtered through the filter 21 for dust removal. The air entering the shell 1 rotates circumferentially inside the shell 1 through the No. 1 impeller 4, and is finally discharged through the air outlet pipe 3;

[0033] When the impeller No. 1 4 drives the air to rotate in the casing 1, the energy storage component 7 recovers the useless potential energy therein. After the recovery, the energy storage component 7 converts the potential energy into kinetic energy to drive the cleaning component 6 to rotate, thereby cleaning the filter 21 and ensuring the stability of the air intake during the operation of the fan.

[0034] The present application stores energy in the energy storage component 7 through the No. 1 impeller 4 during normal operation, so that the energy storage component 7 drives the cleaning component 6 to work, thereby ensuring the stability of the air intake volume inside the fan.

[0035] In one embodiment of the present invention, reference Figure 3 The cleaning assembly 6 includes a gear ring 61 and a gear 63; the gear ring 61 is rotatably connected to the inner wall of the air inlet pipe 2, and a scraper 62 is fixedly connected to the middle of the gear ring 61; the scraper 62 is in contact with the filter 21; the gear 63 is rotatably connected to the outer wall of the air inlet pipe 2 and meshes with the gear ring 61; a driving assembly 64 is connected to the gear 63.

[0036] During the implementation process, when the No. 1 impeller 4 is working, the driving component 64 will be operated, and the driving component 64 drives the gear 63 to rotate, the gear 63 drives the ring gear 61 to rotate, and the ring gear 61 drives the scraper 62 to rotate on the filter 21, so that the scraper 62 sticks to the surface of the filter 21 to scrape off the dust on the filter 21, preventing the ventilation holes on the filter 21 from being blocked, ensuring the stability of the ventilation volume of the filter 21 during the operation of the No. 1 impeller 4, and achieving the effect of cleaning the filter 21 to ensure the operating efficiency of the fan.

[0037] In order to facilitate the installation of the gear ring 61, a bearing 611 is arranged between the end of the gear ring 61 close to the filter screen 21 and the air inlet pipe 2. During the installation of the gear ring 61, the bearing 611 is sleeved on the gear ring 61, and then the bearing 611 is installed inside the air inlet pipe. The bearing 611 facilitates the rotation of the gear ring 61 inside the air inlet pipe 2, thereby preventing the gear ring 61 from generating friction with the air inlet pipe 2.

[0038] The scraper 62, the gear ring 61 and the gear 63 are made of stainless steel. The stainless steel scraper 62 has a high hardness and can more effectively scrape off the stubborn dust on the surface of the metal filter 21; the stainless steel material has excellent resistance to a variety of corrosive media; due to its corrosion resistance and hardness, the stainless steel scraper 62 usually has a long service life, which improves the service life of the scraper 62, the outer gear disc and the driving gear 63;

[0039] In one embodiment of the present invention, reference Figure 4The driving assembly 64 includes a No. 2 impeller 641; the No. 2 impeller 641 is fixedly connected to the gear 63; one end of the air duct 642 is connected to the interior of the No. 2 impeller 641 housing 1, and the other end of the air duct 642 is connected to the energy storage assembly 7; the energy storage assembly 7 is used to drive the No. 2 impeller 641 to rotate through the air duct 642.

[0040] In one embodiment of the present invention, reference Figure 5 , the energy storage assembly 7 includes a conduit 71 and an annular tube 72; the annular tube 72 is sleeved on the outside of the housing 1; a plurality of conduits 71 are evenly distributed and installed on the housing 1, one end of the conduit 71 is connected to the inside of the housing 1, and the other end of the conduit 71 is connected to the annular tube 72; reference Figure 6 and Figure 7 A piston 73 is slidably provided at one end of the conduit 71 close to the inside of the shell 1, and a rubber plug 74 is provided at the end of the conduit 71 away from the inside of the shell 1; a fixing frame 76 is fixedly connected between the piston 73 and the rubber plug 74 in the conduit 71; a return spring 77 is provided between the piston 73 and the fixing frame 76; a spring sheet 75 is provided between the rubber plug 74 and the fixing frame 76; a ventilation valve 78 is connected to the conduit 71 between the piston 73 and the rubber plug 74.

[0041] During the implementation process, when the No. 1 impeller 4 is working, the No. 1 impeller 4 rotates and drives the air to hit the inner wall of the shell 1, so that part of the gas enters the inside of the conduit 71, and the gas squeezes the piston 73 inside the conduit 71. The piston 73 pushes the return spring 77, so that the return spring 77 is compressed, and the piston 73 squeezes the gas inside the conduit 71 to push the rubber plug 74 to move, and the spring sheet 75 is stretched, so that the gas inside the conduit 71 enters the inside of the annular tube 72; when the gas inside the conduit 71 escapes, the rubber plug 74 is reset under the action of the spring sheet 75, and the port of the conduit 71 is sealed again, and the piston 73 is reset by the cooperation of the return spring 77 and the air exchange valve 78; under the reciprocating motion of the piston 73 and the rubber plug 74, the gas inside the conduit 71 is filled into the inside of the annular tube 72 for collection and storage, so as to achieve the purpose of potential energy recovery;

[0042] In order to facilitate the conversion of potential energy into kinetic energy, the No. 2 impeller 641 is installed coaxially with the gear 63, and the end of the air duct 642 close to the air inlet pipe 2 is obliquely corresponding to the top of the No. 2 impeller 641; when the collected potential energy is converted into kinetic energy for driving the gear 63 to rotate, the compressed air inside the ring tube 72 is introduced into the chamber corresponding to the air inlet pipe 2 and the No. 2 impeller 641 through the air duct 642, and the No. 2 impeller 641 is pushed to rotate clockwise under the action of the air duct 642, and the No. 2 impeller 641 drives the gear 63 to rotate through the shaft, so as to achieve the purpose of potential energy conversion, reduce the consumption of mechanical energy, and achieve the purpose of energy saving.

[0043] In one embodiment of the present invention, reference Figure 4 , the scraper 62 is S-shaped.

[0044] During the implementation process, the S-shaped scraper 62 allows the edge of the scraper 62 to more flexibly fit the curves or concave-convex parts of the surface of the filter 21 during the process of the scraper 62 rotating on the filter 21, thereby reducing cleaning dead corners; in addition, the flexibility of the S shape helps to reduce the hard contact between the scraper 62 and the filter 21, reducing the wear of the filter 21; the two ends of the scraper 62 can be set at an angle to facilitate the synchronous cleaning of dust accumulated on the inner wall of the ring gear 61.

[0045] In one embodiment of the present invention, the guide tube 71 is arranged to be inclined toward the rotation direction of the first impeller 4 .

[0046] During the implementation process, when the potential energy is recovered, since a triangle protrudes from one end of the conduit 71 located inside the shell 1, part of the air will directly enter the conduit 71 during the rotation of the air to squeeze the piston 73 to move, thereby recovering the useless potential energy without affecting the normal use of the fan.

[0047] In one embodiment of the present invention, a fixing ring 711 is fixedly provided inside the conduit 71 at one end of the piston 73 away from the rubber stopper 74. In order to limit the moving position of the piston 73, during the reciprocating motion of the piston 73, the fixing frame 76 cooperates with the fixing ring 711 to limit the moving distance of the piston 73 inside the conduit 71, thereby preventing the piston 73 from moving out of the conduit 71.

[0048] In one embodiment of the present invention, reference Figure 7 The outer ring of the piston 73 is provided with a sealing ring ( Figure 7 The outer ring of the piston is not numbered). The sealing ring is made of an existing rubber O-ring. During the reciprocating motion of the piston 73, the elasticity of the sealing ring can reduce the gap between the piston 73 and the conduit 71, so as to seal the gap between the piston 73 and the conduit 71;

[0049] In one embodiment of the present invention, reference Figure 1 The air inlet pipe 2 is hinged with a cover plate 8 at one side away from the end of the housing 1. The cover plate 8 is slidably plugged with a bolt 81 threadedly connected to the housing 1. When the fan is not in use, the cover plate 8 is closed, and then the movable end of the cover plate 8 is fixed to the air inlet pipe 2 by the bolt 81, so as to shield the port of the air inlet pipe 2 from dust and prevent external dust from entering the interior of the air inlet pipe 2.

[0050] In one embodiment of the present invention, reference Figure 1 and Figure 2, also includes a dust collecting component 9; the dust collecting component 9 includes a dust guide pipe 92 and a collecting box 91; one end of the dust guide pipe 92 is connected to the air inlet pipe 2, and the other end of the dust guide pipe 92 is connected to the collecting box 91; a collecting box 93 is slidably installed in the collecting box 91.

[0051] During the implementation process, when the filter 21 is dusted for a long time, there will be a problem of accumulation of cleaned dust in the air inlet duct 2; so after the dust on the filter 21 is scraped off by the scraper 62, the dust is introduced into the dust guide tube 92 along the scraper 62, and then enters the collection box 93 in the collection box 91 along the dust guide tube 92; at the same time, the shape of the scraper 62 is also convenient for the dust collected on the scraper 62 to fall into the dust guide tube 92 along the arc and inclination angle of the scraper 62; the collection box 93 is located in the collection box 91 and remains in a sealed state. When the amount of dust in the collection box 93 accumulates to a certain amount, the collection box 93 is taken out to clean the dust, and then the collection box 93 is put into the collection box 91; in order to facilitate the removal of the collection box 93 out of the collection box 91, a handle 931 is fixed on the collection box 93. When the dust in the collection box 93 is processed, the collection box 93 can be moved out from the collection box 91 through the handle 931, and then the dust in the collection box 93 can be poured into the processing barrel, which is convenient for operation.
