[0046] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0047] The present invention provides the following preferred embodiments

[0048] like Figure 1-11As shown, a green building ventilation and filtering device includes a mounting frame 1 and a clean air exhaust pipe 2. When working, the clean air exhaust pipe 2 is connected to the building ventilation duct through a flexible joint. An axial flow fan is installed inside the clean air exhaust pipe 2. When the filtering device is working, the axial flow fan and the motor 3 work continuously. The mounting frame 1 is provided with a motor 3, and the mounting frame 1 is provided with a filter housing 4 driven by the motor 3 and capable of reciprocating up and down vibration;

[0049] It also includes a convex shaft 11 rotatably connected to the mounting frame 1, the output shaft end of the motor 3 is transmission-connected to the convex shaft 11 via a first belt, a cam 12 is mounted on the convex shaft 11, a vibration guide wheel 13 is rotatably mounted on the back of the filter housing 4, the cam 12 is adaptively connected to the vibration guide wheel 13, and a group of elastic reset parts 14 are installed between the filter housing 4 and the air inlet box 5.

[0050] When the ventilation and filtration operation of the green building is performed, the motor 3 outputs the speed at the set power. After the motor 3 outputs the speed, the filter housing 4 and the filter cartridge 9 can reciprocate within the set stroke through the arrangement of the cam 12, the vibration guide wheel 13 and the elastic reset member 14, thereby realizing the vibration shaking-off of the impurities filtered out of the outer surface of the filter cartridge 9;

[0051] The top of the mounting frame 1 is connected to an air inlet box 5, and the air inlet box 5 is slidably connected to the filter housing 4;

[0052] An air control module is installed inside the air inlet box 5, and the air control module controls the air inlet box 5 to periodically inlet air into the filter housing 4;

[0053] The wind control module includes a group of ventilation valve channels 15 opened in the air inlet box 5, and the top and bottom of the ventilation valve channel 15 are provided with ventilation holes. A valve column 16 is rotatably installed on the inner wall of the ventilation valve channel 15. A group of valve columns 16 are linked by a second belt. The inside of the valve column 16 is fixed with an air flow channel 46 with openings at both ends. A third belt is installed on the convex shaft 11 for transmission. An upper circular shaft 17 is rotatably installed on the air inlet box 5, and a missing gear 18 is installed on the upper circular shaft 17. A transmission tooth surface is fixedly provided on the missing gear 18, and the full arc of the transmission tooth surface is 90°. A transfer gear 19 is installed on the valve column 16, and the transmission tooth surface is evenly distributed with teeth meshing with the transfer gear 19.

[0054] When the ventilation and filtering operation of the green building is performed, the ventilation valve channel 15 and the ventilation channel 46 are arranged so that the ventilation valve channel 15 is periodically connected with the ventilation channel 46, and then the air inlet box 5 is periodically supplied with air into the filter housing 4;

[0055] In each transmission connection cycle between the missing gear 18 and the indexing gear 19, the valve column 16 rotates 90°, and the ventilation valve channel 15 can only achieve the circulation between the ventilation valve channel 15 and the ventilation channel 46 when it is parallel to the ventilation channel 46. Therefore, the ventilation valve channel 15 and the ventilation channel 46 can only be circulated when the missing gear 18 rotates a specified number of times, and then when the missing gear 18 rotates, the ventilation valve channel 15 and the ventilation channel 46 are periodically connected, and only when the ventilation valve channel 15 and the ventilation channel 46 are connected, the air inlet box 5 can take in air, and then the air inlet box 5 can periodically take in air into the filter housing 4;

[0056] During the non-connected period between the air inlet box 5 and the filter housing 4, the internal pressure in the filter housing 4 is cyclically changed by setting the axial flow fan in the clean air exhaust pipe 2. The suction pressure and suction intensity of the axial flow fan on the filter cartridge 9 are cyclically changed by cyclic switching of the internal pressure in the filter housing 4. The suction pressure and suction intensity are cyclically adjusted to effectively improve the self-absorption intensity of the debris blocking the filter holes, and then the self-cleaning and self-maintenance of the filter cartridge 9 are achieved by changing the internal pressure.

[0057] A wind direction circulation regulating component is installed inside the filter housing 4 and at a position corresponding to the lower part of the air inlet box 5. The wind direction circulation regulating component circulates and changes the ventilation direction inside the filter housing 4.

[0058] Two induced air cylinders 6 are installed on the filter housing 4, and the air outlet ends of the two induced air cylinders 6 are connected to the clean air exhaust pipe 2;

[0059] The inner wall of the filter housing 4 is slidably connected to two symmetrically arranged vibration frames 7, and the inner walls of the two vibration frames 7 are both rotatably mounted with air guide cyclones 8, a filter cartridge is rotatably sleeved between the two air guide cyclones 8, the air suction end of the air induced cylinder 6 is connected to the inner cavity of the filter cartridge 9, and the filter cartridge 9 and the air guide cyclone 8 are both driven by the motor 3 and rotate in opposite directions at differential speeds;

[0060] It also includes an upper tensioning block 20 slidably connected to the mounting frame 1, a limit spring 21 limited by the mounting frame 1 is installed on the side of the tensioning block 20, a tensioning wheel 22 is rotatably installed on the tensioning block 20, an outer shaft 23, a middle shaft 24 and an inner shaft 25 are rotatably installed on the filter housing 4, the outer shaft 23 and the tensioning wheel 22 are both connected to the third belt transmission, a first bevel gear is installed on the outer shaft 23 and the middle shaft 24, the two first bevel gears are meshed with each other, a fourth belt is connected to the middle shaft 24 and the inner shaft 25, a gear roller 26 is installed on the inner shaft 25, a passive gear ring is fixedly installed on an air guide cyclone 8, the passive gear ring is connected to the gear roller 26, the axis of the gear roller 26 is parallel to the axis of the air guide cyclone 8, and the tooth length of the gear roller 26 is 9 times the tooth length of the passive gear ring.

[0061] When the ventilation and filtering operation of the green building is performed, the gear roller 26 rotates at a set speed. After the gear roller 26 rotates, it drives the air guide vortex drum 8 to rotate. By setting the ratio of the tooth length of the gear roller 26 to the length of the passive gear ring, the gear roller 26 can continuously drive the air guide vortex drum 8 during the reciprocating movement of the vibration frame 7 and the air guide vortex drum 8 along the axial direction of the filter housing 4.

[0062] It also includes a reversing shaft 32 rotatably mounted on a vibration frame 7, a reversing bevel gear is mounted on the reversing shaft 32, a second bevel gear is mounted on the filter element barrel 9 and an air guide vortex barrel 8, the two second bevel gears are both transmission-connected with the reversing bevel gear, and the reversing bevel gear is arranged between the two second bevel gears.

[0063] When in use, the filter cartridge 9 is set so that the air guide vortex 8 and the filter cartridge 9 are in a coaxial counter-rotating state. The coaxial counter-rotating of the air guide vortex 8 and the filter cartridge 9 allows various parts of the filter cartridge 9 to undergo cyclic deformation, thereby achieving the all-round density and extrusion-type self-maintenance effect of the filter cartridge 9.

[0064] An elastic section 10 is fixedly provided on the filter element barrel 9, and filter holes are evenly distributed on the elastic section 10. A group of deformation drive modules cooperating with the elastic section 10 are installed between the two air guide cyclones 8. A pulse back-cleaning module for backwashing and self-cleaning the filter holes is provided in the filter element barrel 9. A reciprocating drive member is provided in the filter housing 4, and the two air guide cyclones 8 are driven by the reciprocating drive member.

[0065] The reciprocating drive member includes a half-face gear 27 installed on the central shaft 24, a reciprocating screw 28 rotatably connected to the filter housing 4, a driven gear 29 fixedly installed at the tail end of the reciprocating screw 28, a first torsion spring 30 is provided at the rotation connection between the reciprocating screw 28 and the filter housing 4, the half-face gear 27 is adaptively connected to the driven gear 29, and a positive thread segment and a negative thread segment are respectively provided on the reciprocating screw 28, and a drive ring 31 is transmission-mounted on the positive thread segment and the negative thread segment, and the two drive rings 31 are respectively rotatably connected to the two air guide vortex drums 8.

[0066] When in use, the half-face gear 27 and the first torsion spring 30 are arranged so that the reciprocating screw 28 can reciprocate forward and reverse within a set period. After the reciprocating screw 28 reciprocates forward and reverse within the set period, the spacing between the two vibration frames 7 or the two air guide cyclones 8 is reciprocatedly changed. When the spacing between the two vibration frames 7 or the two air guide cyclones 8 is reciprocatedly changed, the elastic section 10 on the filter cartridge 9 is reciprocatedly deformed or reciprocated outwardly supported. The reciprocating deformation of the elastic section 10 enables the filter hole to be reciprocatedly deformed and the deformation of the filter hole is used to squeeze out the impurities or dirt blocked in the filter hole. The forced deformation of the filter cartridge 9 and the realization of the extrusion-type sparseness effect can effectively maintain the ventilation smoothness of the filter cartridge 9 and maintain the high air filtering performance of the filter cartridge 9.

[0067] When the elastic section 10 is reciprocated and outwardly supported, the filter hole is deformed, and this expansion structure acts in the vertical direction of the filter hole instead of the horizontal direction of the filter hole because the expansion direction acts on the filter hole. The circular hole structure of the filter hole tends to be a waist-shaped hole, and the aperture of the waist-shaped hole will only become smaller or not larger than the original aperture of the filter hole. When the elastic section 10 is deformed, the elastic section 10 rotates centrifugally, and the centrifugal force of the impurities in the filter hole is greater than the gravity of the impurities in the filter hole. Therefore, the impurities in the deformed filter hole will not enter the inner cavity of the elastic section 10, but will only be thrown out of the elastic section 10 under the action of centrifugal force, thereby avoiding the impurities from flowing into the elastic section 10.

[0068] The wind direction circulation adjustment component includes a differential shaft 33 rotatably connected to the filter housing 4, the differential shaft 33 is transmission-connected to the inner shaft 25 via a fifth belt, a group of louvers 34 distributed in a linear array are rotatably mounted on the inner wall of the filter housing 4, and a group of louvers 34 are linked via a sixth belt;

[0069] The inner wall of the sixth belt is evenly distributed with transmission teeth, and each shutter plate 34 is provided with a pulley matched with the transmission teeth, and the pulley is evenly distributed with tooth grooves that mesh with the transmission teeth;

[0070] Then, a set of louvers 34 can be effectively linked via the sixth belt;

[0071] A differential bevel gear is installed on the louver plate 34, and a second torsion spring 35 is fixedly installed at the rotation connection between the louver plate 34 and the filter housing 4. Two swing bevel gears 36 are installed on the differential shaft 33. Both swing bevel gears 36 are provided with a bevel tooth surface, and the full arc of the bevel tooth surface is 90°. The differential bevel gear is arranged between the two swing bevel gears 36, and the bevel tooth surfaces on the two swing bevel gears 36 are staggered by 180°.

[0072] When performing ventilation and filtering operations in green buildings, the two swinging bevel teeth 36 are arranged so that the louver 34 can swing back and forth within a set angle. The reciprocating swing of the louver 34 can cyclically change the direction of the airflow toward the filter cartridge 9. The cyclic change of the direction of the airflow toward the filter cartridge 9 can effectively reduce the probability of impurities in the airflow clogging the filter holes.
