Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to an automatic cleaning and dust removal device for the condenser of an air-cooled chiller. Background Technique

[0002] An air-cooled chiller is a commonly used refrigeration device in the industrial field. It utilizes the good heat exchange performance of the condenser, the large contact area with air, and the condensing fan to accelerate the air flow rate, so that the refrigerant exchanges heat with air in the condenser to achieve a good heat exchange effect. The schematic diagram of the operation of the condensing fan and the heat exchange of the condenser during the normal operation of the chiller is as shown in the appendix Figure 6 as follows.

[0003] During the operation of the chiller, due to the operation of the condensing fan, the air flow is accelerated, the heat exchange effect of the condenser is improved, and dust, leaves, feathers and other sundries in the air are adsorbed on the surface of the condenser, which affects the heat exchange effect of the condenser and reduces the energy efficiency of the chiller.

[0004] Therefore, in view of the above problems, an automatic cleaning and dust removal device for the condenser of an air-cooled chiller is proposed to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model develops an automatic cleaning and dust removal device for the condenser of an air-cooled chiller. The utility model achieves the cleaning effect by cleaning the dirt adsorbed on the surface of the condenser with high-pressure water flow.

[0006] The technical solution for the utility model to solve the technical problem is: The utility model provides an automatic cleaning and dust removal device for the condenser of an air-cooled chiller, including a chiller, in which a condenser is installed; a water supply main pipe, on which a water pump is installed, the water supply main pipe is fixedly connected to a water storage tank, the water supply main pipe is fixedly connected to a water softener, and a solenoid valve is installed on the water supply main pipe; a water spray pipe, arranged on one side of the air inlet of the condenser, and the water spray pipe is fixedly connected to a group of nozzles. By adopting the water spray pipe and the nozzles, the nozzles spray high-pressure water flow to clean the dirt adsorbed on the surface of the condenser.

[0007] As an optimization, an installation bracket is connected to the air inlet of the condenser corresponding to the chiller. The installation bracket is connected to symmetric vertical slots. One of the vertical slots is connected to a motor. The output shaft of the motor passes through the corresponding vertical slot and is connected to a screw rod. The screw rod is connected to the corresponding vertical slot by bearings. The other vertical slot is connected to a guiding vertical rod. One end of a lifting frame is respectively arranged in the symmetric vertical slots. One end of the screw rod is threadedly connected to one end of the lifting frame. The guiding vertical rod passes through the other end of the lifting frame. The lifting frame is connected to symmetric special-shaped frames. The symmetric special-shaped frames are respectively connected to the water spraying pipe by bearings. By adopting a liftable water spraying pipe, it is convenient to clean the dirt adsorbed on the surface of the condenser.

[0008] As an optimization, one of the vertical slots is connected to a rack. The rack meshes with a gear. The central axis of the gear is connected to the corresponding special-shaped frame by bearings. The central axis of the gear is connected to a turntable. An eccentric part of the turntable is connected to a power circular block. The water spraying pipe is connected to a straight port groove. The power circular block is arranged in the straight port groove. By arranging the power circular block in the straight port groove, the reciprocating swing of the water spraying pipe is realized, and the dirt adsorbed on the surface of the condenser is cleaned.

[0009] As an optimization, the symmetric special-shaped frames are respectively connected to the central axis of a brush by bearings. The central axes of the brush and the gear are respectively connected to synchronous pulleys. Both ends of a synchronous belt respectively surround the corresponding synchronous pulleys.

[0012] As an optimization, the installation angles of a group of nozzles are different. During the cleaning process, the water flow sprayed by the nozzles can cover the entire surface of the condenser due to the different nozzle angles, achieving the effect of comprehensive cleaning.

[0013] As an optimization, a group of nozzles are distributed in a broken line along the unfolded surface of the side of the water spraying pipe.

[0027] As Figures 1 to 5 shown, Embodiment 1: An automatic cleaning and dust removal device for the condenser of an air-cooled chiller, including a chiller 1, in which a condenser 2 is installed; a water supply main pipe 3, on which a water pump 5 is installed, the water supply main pipe 3 is fixedly connected to a water storage tank 6, the water supply main pipe 3 is fixedly connected to a water softener 7, and a solenoid valve 4 is installed on the water supply main pipe 3; a water spray pipe 9, arranged on one side of the air inlet of the condenser 2, and the water spray pipe 9 is fixedly connected to a group of nozzles 8. By adopting the water spray pipe 9 and the nozzles 8, the nozzles 8 spray high-pressure water flow to clean the dirt adsorbed on the surface of the condenser 2.

[0028] A group of the nozzles 8 are equidistantly distributed along the axis direction of the water spray pipe 9.

[0029] The installation angles of a group of the nozzles 8 are different. During the cleaning process, the water flow sprayed by the nozzles 8 can cover the entire surface of the condenser due to the different angles of the nozzles 8, achieving the effect of comprehensive cleaning.

[0030] A group of the nozzles 8 are distributed in a broken line along the unfolded surface of the side of the water spraying pipe 9.

[0031] A visual sensor is installed at a suitable position facing the air inlet of the condenser 2 in the chiller 1, and the visual sensor is electrically connected to the controller.

[0032] The solenoid valve 4 and the water pump 5 are respectively electrically connected to the controller.

[0033] The working process of this embodiment is as follows:

[0034] The water spraying pipe 9 is installed in the chiller 1. The water spraying pipe 9 is fixedly communicated with the water supply main pipe 3 through a hose.

[0035] The water supply main pipe 3 is connected to tap water, and through the tap water system, the tap water is conveyed into the water softener 7. After the water softener 7 processes the tap water, it enters the water storage tank 6.

[0036] When the surface of the condenser is blocked due to adsorption of dirt, the visual sensor sends the information to the controller, and the controller controls the water pump 5 and the solenoid valve 4 to work. The water pump 5 pumps the tap water in the water storage tank 6 and pressurizes it. The high-pressure water enters the water spraying pipe 9, and the water flow sprayed from the nozzles 8 can cover the entire surface of the condenser 2 due to the different angles of the nozzles 8, achieving the effect of comprehensive cleaning.

[0037] Embodiment 2: This embodiment is further elaborated on the basis of Embodiment 1. The air inlet of the chiller 1 corresponding to the condenser 2 is connected with an installation bracket 23. The installation bracket 23 is connected with symmetric vertical grooves 12. One of the vertical grooves 12 is connected with a motor 10. The output shaft of the motor 10 passes through the corresponding vertical groove 12 and is connected with a screw rod 11. The screw rod 11 is connected with the corresponding vertical groove 12 through a bearing. The other vertical groove 12 is connected with a guiding vertical rod 13. One end of a lifting frame 14 is respectively arranged in the symmetric vertical grooves 12. One end of the screw rod 11 is threadedly connected with one end of the lifting frame 14. The guiding vertical rod 13 passes through the other end of the lifting frame 14. The lifting frame 14 is connected with symmetric special-shaped frames 24. The symmetric special-shaped frames 24 are respectively connected with the water spraying pipe 9 through bearings. By adopting the liftable water spraying pipe 9, it is convenient to realize the cleaning of the dirt adsorbed on the surface of the condenser 2.

[0038] One of the vertical grooves 12 is connected with a rack 19. The rack 19 meshes with a gear 18. The central shaft of the gear 18 is connected with the corresponding special-shaped frame 24 through a bearing. The central shaft of the gear 18 is connected with a turntable 22. An eccentric part of the turntable 22 is connected with a power circular block 21. The water spraying pipe 9 is connected with a straight port groove 20. The power circular block 21 is arranged in the straight port groove 20. By arranging the power circular block 21 in the straight port groove 20, the reciprocating swing of the water spraying pipe 9 is realized, and the cleaning of the dirt adsorbed on the surface of the condenser 2 is realized.

[0039] The symmetrically shaped frames 24 are respectively connected to the central axes of the brushes 15 by bearings. The central axes of the brushes 15 and the central axis of the gear 18 are respectively connected to the synchronous pulleys 16. Both ends of the synchronous belt 17 respectively surround the corresponding synchronous pulleys 16. By adopting the synchronous belt mechanism, the rotation of the brushes 15 is realized. The brushes 15 move and rotate along the air inlet area of the condenser 2, contact and adsorb dirt, and achieve the removal of dirt.

[0040] The brushes 15 are hard bristle brushes.

[0041] The motor 10 is electrically connected to the controller.

[0042] The working process of this embodiment is as follows:

[0043] The water spray pipe 9 is fixedly connected to the water supply main pipe 3 through a hose. During cleaning, the controller controls the motor 10 to rotate. The motor 10 drives the screw 11 to rotate. The screw 11 drives the lifting frame 14 to move along the guiding vertical rod 13 in the vertical groove 12. The lifting frame 14 drives the shaped frame 24, the brushes 15, the gear 18, the synchronous pulleys 16, the synchronous belt 17, the turntable 24, the power circular block 21, the water spray pipe 9, the nozzle 8 and the straight slot 20 to move. During the movement, the gear 18 meshes and rotates with the rack 19. The gear 18 drives the turntable 22 and one synchronous pulley 16 to rotate. The turntable 22 drives the power circular block 21 to swing in the straight slot 20. The power circular block 21 drives the straight slot 20 to swing reciprocally. The straight slot 20 drives the water spray pipe 9 to rotate reciprocally. The water spray pipe 9 drives the nozzle 8 to swing reciprocally. One synchronous pulley 16 drives the other synchronous pulley 16 and the brushes 15 to rotate through the synchronous belt 17. The water flow sprayed by the reciprocally swinging nozzle 8 can cover the entire surface of the condenser 2, achieving the effect of comprehensive cleaning. The brushes 15 move and rotate along the air inlet area of the condenser 2, contact and adsorb dirt, and achieve the removal of dirt.

[0044] Although the specific implementation manners of the utility model are described above in conjunction with the drawings, it is not a limitation to the protection scope of the utility model. Based on the technical solutions of the utility model, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the utility model.
