Description

Technical Field

[0001] The present invention relates to the technical field of building ventilation equipment, and particularly relates to a dust removal device for building ventilation equipment. Background Art

[0002] Ventilation equipment is a municipal infrastructure for air circulation between the inside and outside of a building, enabling efficient circulation of indoor and outdoor air. Currently, when ventilation equipment is in use, dust carried in the air accumulates on the filter screen. As the amount of accumulated dust increases, the filter screen will become clogged, resulting in the inability to carry out ventilation operations normally, that is, there are certain drawbacks.

[0003] To solve the above problems, a ventilation equipment that can remove dust from the filter screen has emerged on the market. The equipment includes a ventilation pipe, a ventilation component arranged in the ventilation pipe, and a dust removal component arranged on both sides of the ventilation pipe; the dust removal component includes a filter screen and a vibration motor arranged on the filter screen; the filter screen is connected to the ventilation pipe; when the equipment is in use, the air inside the building is exchanged with the outside air through the ventilation component, so that the dust carried in the air can be filtered through the filter screen; during the filtering of the dust in the air by the filter screen, the vibration motor is started, so that the vibration motor can drive the filter screen to vibrate, thereby reducing the amount of dust adhering to the filter screen and reducing the probability of the filter screen being clogged, that is, ensuring that the ventilation operation can be carried out efficiently.

[0004] The above device has the following problems in actual use: when the device filters the dust in the air, since a large amount of dust is carried in the air, the particle sizes of the dust are different, so the filter screen can only filter out a part of the dust, resulting in some dust still entering the ventilation pipe and adhering to the fan blades of the ventilation component. If the dust on the fan blades cannot be cleaned, the ventilation effect of the fan blades will be weakened and the ventilation efficiency of the fan blades will be reduced. Summary of the Invention

[0005] The present invention provides a dust removal device for building ventilation equipment to solve the problem that the existing ventilation equipment cannot clean the dust adhering to the fan blades.

[0006] To achieve the above object, the present invention adopts the following technical solution: A dust removal device for building ventilation equipment, including an air duct, filter plates respectively fixed on both sides of the air duct, and further including a ventilation mechanism and a dust removal mechanism arranged in the air duct; the ventilation mechanism includes a rotating shaft, a plurality of ventilation blades arranged equidistantly along the circumferential direction of the rotating shaft, and a driving component for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the filter plate; the ventilation blades are fixedly connected to the rotating shaft; the dust removal mechanism includes a liquid storage cylinder, a dust removal component arranged on the liquid storage cylinder, and an installation hole opened on the air duct; the liquid storage cylinder is fixedly connected to the installation hole; the dust removal component includes a side pipe, a bottom pipe, a first guide rod, dust removal parts arranged equidistantly on both sides of the side pipe along the length direction of the side pipe, and a plurality of dust removal holes opened equidistantly on the bottom pipe along the length direction of the bottom pipe; the side pipe is communicated with the liquid storage cylinder; the bottom pipe is communicated with the side pipe, and the dust removal holes face the ventilation blades; the first guide rod is fixedly connected to the side pipe; the dust removal part includes a first nut seat, a long block, side plates, a sponge brush, and a power unit for driving the first nut seat to reciprocate along the length direction of the first guide rod; the first nut seat is slidably connected to the first guide rod; the long block is fixedly connected to the first nut seat; the side plates are fixedly connected to the long block; the sponge brush is fixedly connected to the side plates, and the sponge brush is in contact with the ventilation blades.

[0007] The principle and advantages of this solution are:

[0008] 1. Install the air duct at the ventilation hole of the building and use the driving component to drive the ventilation blades to rotate. During the rotation of the ventilation blades, the air inside the building and the air outside the building can be exchanged and circulated, thereby enhancing the air flow effect inside the building and improving the air quality inside the building.

[0009] 2. During the rotation of the ventilation blades, the cleaning liquid in the liquid storage cylinder will flow through the side pipe, the bottom pipe, and then be discharged through the dust removal holes, and finally act on the ventilation blades. Through the above movement, the cleaning liquid can preliminarily clean the dust adhering to the ventilation blades, thereby reducing the amount of dust adhering to the ventilation blades, and thus enhancing the ventilation effect of the ventilation blades, enabling the air inside the building to be efficiently exchanged with the outside air.

[0010] 3. During the cleaning of the ventilation blades by the cleaning liquid, the power unit drives the sponge brush to reciprocate along the length direction of the first guide rod, so that the sponge brush has a certain acting force. Therefore, under the action of the sponge brush, the dust adhering to the ventilation blades can be deeply cleaned, thereby further reducing the amount of dust adhering to the ventilation blades, enabling the ventilation blades to more efficiently promote the exchange of air inside the building and the outside air, that is, enhancing the ventilation effect.

[0011] Further, it further includes jetting parts symmetrically arranged on both sides of the bottom pipe along the length direction of the bottom pipe; the jetting parts include a number of jetting units arranged at equal intervals along the length direction of the bottom pipe; each jetting unit includes a side pipe, a movable pipe, and a number of jetting holes opened at equal intervals on the movable pipe along the length direction of the movable pipe; the side pipe is communicated with the bottom pipe; the movable pipe is slidably connected to the inner wall of the side pipe; the long block is fixedly connected with a long plate, and a number of movable pipes are all fixedly connected with the long plate.

[0012] The setting of the movable pipe is to expand the range of the discharge of the cleaning liquid, so that the cleaning liquid can more fully and comprehensively wash different positions of the ventilation blades, further improving the flushing efficiency of the cleaning liquid on the ventilation blades and ensuring the quality of the flushing of the cleaning liquid on the ventilation blades.

[0013] During the period when the cleaning liquid is ejected along the jetting holes through the side pipe and the movable pipe, the long block drives the movable pipe to reciprocate along the length direction of the side pipe through the long plate. During the movement of the movable pipe, the position of the cleaning liquid ejected from the jetting holes can be changed, so that the cleaning liquid can more thoroughly wash different positions on the ventilation blades, further improving the flushing effect of the cleaning liquid on the ventilation blades. Therefore, through the change in the position of the movable pipe, the effect of the jetting holes is enhanced, and the working efficiency of the jetting holes is improved.

[0014] During the movement of the movable pipe, a number of jetting holes will gradually slide into the side pipe, and thus the quantity of the cleaning liquid ejected from the jetting holes will decrease. Therefore, after the quantity of the cleaning liquid that can be ejected from the jetting holes decreases, the pressure of the cleaning liquid ejected from the spray holes outside the side pipe will increase, thereby further strengthening the acting force of the cleaning liquid ejected from the spray holes, enabling the cleaning liquid to more efficiently and thoroughly wash the dust adhering to the ventilation blades, that is, enhancing the flushing effect of the movable pipe on the ventilation blades and improving the flushing quality of the movable pipe on the ventilation blades.

[0015] Further, it further includes auxiliary parts symmetrically arranged on both sides of the side pipe along the length direction of the side pipe; the auxiliary parts include a piston cylinder, a piston block, and an auxiliary block; the piston cylinder is fixedly connected with the side pipe, and an inlet pipe and an outlet pipe are respectively communicated with the piston cylinder, and both the inlet pipe and the outlet pipe are communicated with the side pipe; the piston block is slidably connected with the piston cylinder; both ends of the auxiliary block are fixedly connected with the long block and the piston block respectively.

[0016] During the movement of the long block, the auxiliary block can drive the piston block to reciprocate along the length direction of the piston cylinder under the drive of the long block. Therefore, during the movement of the piston block, the cleaning liquid flowing in the side pipe can be continuously pumped into the piston cylinder and the cleaning liquid in the piston cylinder can be discharged into the side pipe, thereby realizing the pressurization of the cleaning liquid flowing in the side pipe. Through the above movement, after the cleaning liquid is pressurized by the piston cylinder, the acting force of the cleaning liquid discharged from the dust removal holes and the jetting holes is stronger, and the cleaning liquid can more efficiently remove dust from the ventilation blades, thereby comprehensively enhancing the cleaning effect of the cleaning liquid on the ventilation blades.

[0017] Further, it further includes a filling part arranged on the bottom pipe; the filling part includes a sliding hole opened on the bottom pipe, a filling block for sealing the sliding hole, and a driving unit for driving the filling block to reciprocate along the width direction of the bottom pipe; the filling block is slidably connected to the sliding hole.

[0018] By driving the filling block to reciprocate along the width direction of the bottom pipe, during the movement of the filling block, the flow diameter in the entire bottom pipe can be adjusted, thereby increasing the pressure of the cleaning liquid flowing in the bottom pipe. As a result, when the cleaning liquid is discharged from the dust removal holes and the jet holes, the acting force of the cleaning liquid is stronger, making the cleaning of the dust adhered to the ventilation blades by the cleaning liquid more complete, and further improving the flushing quality of the cleaning liquid on the ventilation blades.

[0019] Further, it further includes a mist part arranged in the liquid storage cylinder; the mist part includes a power shaft, a cam, a plurality of mist pipes arranged equidistantly along the circumferential direction of the liquid storage cylinder, and a movement unit for driving the power shaft to rotate; the power shaft is rotatably connected to the liquid storage cylinder; the cam is fixedly connected to the power shaft; the bottom end of the mist pipe is communicated with the bottom of the liquid storage pipe, and the top end of the mist pipe is flush with the lower surface of the cam.

[0020] During the flow of the cleaning liquid in the liquid storage cylinder, the cleaning liquid will be converted through the mist pipes, and then atomized liquid is discharged from the mist pipes. Therefore, during the flow of air in the air duct, the atomized liquid can dust the dust in the air, thereby reducing the amount of dust carried in the air, and thus reducing the amount of dust adhering to the ventilation blades. That is, through the dust reduction of the mist pipes, the ventilation effect of the ventilation blades can be further enhanced, and the ventilation efficiency of the ventilation blades can be improved.

[0021] During the rotation of the cam, the cam can be successively attached to a plurality of atomizing pipes arranged equidistantly in the circumferential direction of the liquid storage cylinder, thereby adjusting the amount of atomized liquid discharged from the mist pipes and controlling the position of the atomized liquid discharged from the mist pipes. Through the above movement, when the cam is attached to the mist pipe, the mist pipe can be blocked, thereby increasing the pressure of the atomized liquid discharged from the remaining mist pipes, so that the range of action of the atomized liquid is wider and the contact with the dust in the air is more comprehensive, further reducing the amount of dust adhering to the ventilation blades and improving the ventilation quality of the ventilation blades.

[0022] Further, it further includes a plurality of wind driving blades arranged equidistantly along the circumferential direction of the power shaft; the wind driving blades are fixedly connected to the power shaft, and the wind driving blades are located below the liquid storage cylinder.

[0023] During the rotation of the power shaft, the wind driving blades rotate synchronously. During the rotation of the wind driving blades, the flow rate of the atomized liquid can be increased, thereby further expanding the range of the discharged atomized liquid, making the contact between the atomized liquid and the dust in the air more comprehensive and sufficient, and thus further enhancing the dust reduction effect of the atomized liquid on the dust in the air and ensuring the dust reduction quality of the atomized liquid on the air.

[0024] Further, it further includes cleaning units symmetrically arranged on both sides of the side pipe along the length direction of the side pipe; the cleaning unit includes a bottom plate, a cleaning shaft, a sponge roller, and a power member for driving the cleaning shaft to rotate; the bottom plate is fixedly connected to the outer wall of the bottom of the liquid storage cylinder; the cleaning shaft is rotatably connected to the bottom plate; the sponge roller is fixedly connected to the cleaning shaft, and the sponge roller is in contact with the air driving blade.

[0025] During the rotation of the air driving blade, the power member drives the sponge roller to rotate, and thus the sponge roller can clean the dust adhering to the air driving blade, thereby reducing the amount of dust adhering to the air driving blade. That is, through the cleaning of the air driving blade by the sponge roller, the effect of the air driving blade on the atomized liquid is further enhanced, ensuring that the atomized liquid can flow in a more sufficient and comprehensive range under the action of the air driving blade.

[0026] Further, the power unit is a first screw; the first screw is rotatably connected to the bottom of the side pipe, and the first nut seat is threadedly connected to the first screw; the two first screws are fixedly connected; it further includes a linkage member; the linkage member includes a guide cylinder, a rack, a spring, a gear, and a bottom hole opened on the side pipe; the guide cylinder is fixedly connected to the inner wall of the side pipe; one end of the rack is slidably connected to the guide cylinder, and the other end of the rack abuts against the cam; the two ends of the spring are respectively connected to the guide cylinder and the rack; the gear is fixedly connected to the first screw, the gear meshes with the rack, and the rack can rotate in the bottom hole.

[0027] During the rotation of the cam, when the convex part of the cam abuts against the rack, the rack moves along the length direction of the side pipe away from the position where the power shaft is located, and the spring is compressed; when the convex part of the cam no longer abuts against the rack, the rack is reset under the action of the spring, and the rack moves along the length direction of the side pipe towards the position where the power shaft is located. Therefore, the rack can make a reciprocating motion along the length direction of the side pipe.

[0028] During the movement of the rack, since the rack meshes with the gear, the gear can drive the first screw to rotate. During the rotation of the first screw, the first nut seat can make a reciprocating motion along the length direction of the first guide rod.

[0029] Further, the driving unit is a slider; the slider is fixedly connected to the filling block; it further includes driving members symmetrically arranged on both sides of the side pipe along the length direction of the side pipe; the driving members include a second screw, a second guide rod, a second nut seat, and a fixing block; the second screw is fixedly connected to the cleaning shaft; the second guide rod is fixedly connected to the bottom plate; the second nut seat is threadedly connected to the second screw, and the second nut seat is slidably connected to the second guide rod; the two ends of the fixing block are respectively fixedly connected to the second nut seat and the slider.

[0030] During the rotation of the cleaning shaft, the second screw rotates synchronously. During the rotation of the second screw, the second nut seat can make a reciprocating motion along the length direction of the second guide rod. During the movement of the second nut seat, the second nut seat can drive the slider to move synchronously through the fixing block.

[0031] Further, the power member is a belt; both ends of the belt are sleeved on the first screw rod and the cleaning shaft respectively.

[0032] During the rotation of the first screw rod, the first screw rod drives the cleaning shaft to rotate synchronously through the belt. Brief Description of the Drawings

[0056] The power member is the belt 40; the two ends of the belt 40 are respectively sleeved on the first screw rod 31 and the cleaning shaft 29.

[0057] Specific implementation process:

[0058] Install the air duct 1 at the ventilation hole of the building, and then start the first motor, and drive the ventilation blade 4 through the output shaft of the first motor. During the rotation of the ventilation blade 4, it can realize the exchange and circulation of the air inside the building and the air outside the building, thereby enhancing the air flow effect inside the building and improving the air quality inside the building.

[0059] The setting of the water inlet pipe 41 is to timely supplement the cleaning liquid into the liquid storage cylinder 5, so as to ensure that there is sufficient cleaning liquid flowing in the liquid storage cylinder 5.

[0060] During the rotation of the ventilation blade 4, the cleaning liquid in the liquid storage cylinder 5 will flow through the side pipe 6 and the bottom pipe 7 under the action of the booster pump, and then be discharged through the dust removal holes 9, and finally act on the ventilation blade 4. Through the above movement, the cleaning liquid can initially clean the dust adhering to the ventilation blade 4, thereby reducing the amount of dust adhering to the ventilation blade 4, enhancing the ventilation effect of the ventilation blade 4, and enabling the air in the building to efficiently exchange with the outside air.

[0061] During the cleaning of the ventilation blade 4 by the cleaning liquid, the power shaft 23 drives the cam 24 to rotate. During the rotation of the cam 24, when the convex part of the cam 24 abuts against the rack 33, the rack 33 moves along the length direction of the side pipe 6 away from the position where the power shaft 23 is located, and the spring is compressed; when the convex part of the cam 24 no longer abuts against the rack 33, the rack 33 resets under the action of the spring, and the rack 33 moves along the length direction of the side pipe 6 towards the position where the power shaft 23 is located. Therefore, the rack 33 can reciprocate along the length direction of the side pipe 6.

[0062] During the movement of the rack 33, since the rack 33 meshes with the gear 34, the gear 34 can drive the first screw 31 to rotate. During the rotation of the first screw 31, the first nut seat 10 can reciprocate along the length direction of the first guide rod 8. During the movement of the first nut seat 10, the first nut seat 10 can drive the sponge brush 13 to reciprocate along the length direction of the first guide rod 8 through the long block 11, thereby enabling the sponge brush 13 to have a certain acting force. Therefore, under the action of the sponge brush 13, the dust adhering to the ventilation blade 4 can be deeply cleaned, further reducing the amount of dust adhering to the ventilation blade 4, enabling the ventilation blade 4 to more efficiently promote the exchange of air in the building with the outside air, that is, enhancing the ventilation effect.

[0063] During the flow of the cleaning liquid in the bottom pipe 7, by setting the movable pipe 16, the range of the discharge of the cleaning liquid is expanded, so that the cleaning liquid can more fully and comprehensively wash different positions of the ventilation blade 4, further improving the flushing efficiency of the cleaning liquid on the ventilation blade 4 and ensuring the quality of the flushing of the ventilation blade 4 by the cleaning liquid.

[0064] During the spraying of the cleaning liquid from the side pipe 15 and the movable pipe 16 along the jet holes 17, the long block 11 drives the movable pipe 16 to reciprocate along the length direction of the side pipe 15 through the long plate 18. During the movement of the movable pipe 16, the position of the cleaning liquid sprayed from the jet holes 17 can be changed, so that the cleaning liquid can more thoroughly wash different positions of the ventilation blade 4, further improving the flushing effect of the cleaning liquid on the ventilation blade 4. Therefore, through the change in the position of the movable pipe 16, the acting effect of the jet holes 17 is enhanced, and the acting efficiency of the jet holes 17 is improved.

[0065] During the movement of the long block 11, the moving pipe 16 can reciprocate along the length direction of the side pipe 15 driven by the long board 18. During the movement of the moving pipe 16, a number of jet holes 17 will gradually slide into the side pipe 15, and thus the amount of cleaning liquid ejected from the jet holes 17 will decrease. Therefore, after the amount of cleaning liquid that can be ejected from the jet holes 17 decreases, the pressure of the cleaning liquid ejected from the spray holes outside the side pipe 15 will increase, so as to further strengthen the acting force of the cleaning liquid ejected from the spray holes, enabling the cleaning liquid to more efficiently and thoroughly wash the dust adhering to the ventilation blade 4, that is, enhancing the flushing effect of the moving pipe 16 on the ventilation blade 4 and improving the flushing quality of the moving pipe 16 on the ventilation blade 4.

[0066] During the movement of the long block 11, the auxiliary block 21 can drive the piston block 20 to reciprocate along the length direction of the piston cylinder 19 driven by the long block 11. Therefore, during the movement of the piston block 20, the cleaning liquid flowing in the side pipe 6 can be continuously drawn into the piston cylinder 19 and the cleaning liquid in the piston cylinder 19 can be discharged into the side pipe 6, thereby realizing the pressurization of the cleaning liquid flowing in the side pipe 6. Through the above movement, after the cleaning liquid is pressurized by the piston cylinder 19, the acting force of the cleaning liquid discharged from the dust removal holes 9 and the jet holes 17 is stronger, and the cleaning liquid can more efficiently remove dust from the ventilation blade 4, thereby comprehensively enhancing the cleaning effect of the cleaning liquid on the ventilation blade 4.

[0067] During the rotation of the first screw 31, the first screw 31 drives the cleaning shaft 29 to rotate through the belt 40. During the rotation of the cleaning shaft 29, the first screw 31 rotates synchronously. During the rotation of the first screw 31, the first nut seat 10 can drive the slider 35 to reciprocate along the width direction of the bottom pipe 7 through the fixed block 39. During the movement of the slider 35, the filling block 22 moves synchronously. During the movement of the filling block 22, the flow diameter in the entire bottom pipe 7 can be adjusted, thereby promoting an increase in the pressure of the cleaning liquid flowing in the bottom pipe 7, so that when the cleaning liquid is discharged from the dust removal holes 9 and the jet holes 17, the acting force of the cleaning liquid is stronger, enabling the cleaning liquid to more completely clean the dust adhering to the ventilation blade 4 and further improving the flushing quality of the cleaning liquid on the ventilation blade 4.

[0068] During the flow of the cleaning liquid in the liquid storage cylinder 5, the cleaning liquid will be converted through the mist pipe 25 and then the atomized liquid will be discharged from the mist pipe 25. Therefore, during the flow of air in the air duct 1, the atomized liquid can reduce the dust in the air, thereby reducing the amount of dust carried in the air and thus reducing the amount of dust adhering to the ventilation blade 4. That is, through the dust reduction of the mist pipe 25, the ventilation effect of the ventilation blade 4 can be further enhanced and the ventilation efficiency of the ventilation blade 4 can be improved.

[0069] During the rotation of the cam 24, the cam 24 can be successively attached to a number of atomizing tubes equidistantly arranged in the circumferential direction of the liquid storage cylinder 5, thereby adjusting the quantity of the atomized liquid discharged from the atomizing tube 25 and controlling the position where the atomizing tube 25 discharges the atomized liquid. Through the above movement, when the cam 24 is attached to the atomizing tube 25, the atomizing tube 25 can be blocked, thereby increasing the pressure of the atomized liquid discharged from the remaining atomizing tubes 25, so that the range of action of the atomized liquid is wider, the contact with the dust in the air is more comprehensive, and further reducing the quantity of dust adhering to the ventilation blade 4, improving the ventilation quality of the ventilation blade 4.

[0070] During the rotation of the power shaft 23, the air driving blade 27 rotates synchronously. During the rotation of the air driving blade 27, the flow rate of the atomized liquid can be increased, thereby further expanding the range of discharge of the atomized liquid, making the contact between the atomized liquid and the dust in the air more comprehensive and sufficient, so as to further enhance the dust reduction effect of the atomized liquid on the dust in the air and ensure the dust reduction quality of the atomized liquid on the air.

[0071] During the rotation of the air driving blade 27, the cleaning shaft 29 drives the sponge roller 30 to rotate, so that the sponge roller 30 can clean the dust adhering to the air driving blade 27, thereby reducing the quantity of dust adhering to the air driving blade 27. That is, through the cleaning of the air driving blade 27 by the sponge roller 30, the acting effect of the air driving blade 27 on the atomized liquid is further enhanced, ensuring that the atomized liquid can flow in a more sufficient and comprehensive range under the action of the air driving blade 27.

[0072] In summary, first, the air flowing into the air inlet pipe 1 is pretreated by the atomized liquid, thereby reducing the quantity of dust carried in the air and reducing the interference effect of the dust on the ventilation blade 4 and the air driving blade 27; then, by expanding the range of action of the cleaning liquid and increasing the acting force of the cleaning liquid, the cleaning liquid can comprehensively and thoroughly clean the ventilation blade 4, thereby improving the air exchange efficiency of the ventilation blade 4 for the air inside and outside the building and ensuring the air circulation quality.
