Description

Technical Field

[0001] The utility model relates to the technical field of air-cooled water chillers, in particular to an air-cooled water chiller capable of preventing dust from clogging a filter screen. Background Art

[0002] Air-cooled chillers are refrigeration equipment that uses air cooling. They achieve cooling effects by reducing the temperature of the refrigerant medium through heat exchange with the outside air. They are often used in industrial, commercial and other fields.

[0003] The existing air-cooled chiller cooling fan filter design has significant defects. During long-term use, dust and other impurities in the working environment will inevitably adhere to the filter, causing the filter to be easily blocked by dust, which not only seriously affects the working efficiency of the cooling fan, but also reduces the overall performance of the chiller, shortening the service life of the chiller and may also lead to more serious failures and losses. Therefore, we propose an air-cooled chiller with a filter that prevents dust from clogging the filter. Utility Model Content

During long-term use, dust and other impurities in the working environment will inevitably adhere to the filter screen, causing the filter screen to be easily clogged by dust, which not only seriously affects the working efficiency of the cooling fan, but also reduces the overall performance of the chiller, not only shortens the service life of the chiller, but may also lead to more serious failures and losses.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air-cooled chiller with anti-dust clogging filter screen, comprising a chiller main body, a top plate is arranged at the upper end of the chiller main body, a transmission rod is arranged at the center of the top plate, reciprocating screws are arranged at both ends of the transmission rod, a motor is fixedly installed at the center of the top of the top plate, a driven gear is fixedly installed at a center position on the surface of the transmission rod, a driving gear is meshedly connected to one side of the driven gear, screw nuts are threadedly connected to one side of the surfaces of two reciprocating screws, chassis are fixedly installed on both sides of the top of the chiller main body, filters are fixedly connected to the tops of the two chassis, brush plates are arranged on one side of the upper ends of the two filters, and a soft brush is fixedly connected to the lower end of the brush plate.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The air-cooled chiller with dust-proof filter blockage has a top plate, a transmission rod, a motor, a driven gear, a driving gear, a reciprocating screw, a screw nut, a brush plate and a soft brush. The motor drives the driving gear and the driven gear to rotate, thereby driving the reciprocating screws at both ends of the transmission rod to rotate. The screw nut drives the soft brush under the brush plate to move back and forth on the filter through a threaded connection, so that the soft brush can continuously clean the filter, effectively avoiding the problem of the filter being blocked by dust, keeping it clean and unobstructed, improving the heat dissipation efficiency of the chiller, and extending the service life of the chiller. At the same time, since the cleaning process is automatic and no human intervention is required, the maintenance cost and workload are greatly reduced, and the reliability and stability of the equipment are improved.

[0015] Brackets are fixedly installed on both sides of the bottom of the top plate 2 , and the two brackets are fixedly connected to the top of the chiller body 1 by bolts, so that the top plate 2 can be fixed on the chiller body 1 .

[0016] The opposite ends of the two reciprocating screws 7 are fixedly connected to the two sides of the transmission rod 3, and the opposite ends of the two reciprocating screws 7 are movably connected to the bearings fixedly installed in the center of the two sides of the top plate 2 to support the rotation of the screw nut 8.

[0017] The motor 4 is fixedly connected to an output shaft through its bottom output end, and the lower end of the output shaft passes through the interior of the top plate 2 and is fixedly connected to the center of the top of the driving gear 6. The motor 4 drives the driving gear 6 to engage the driven gear 5, so that the transmission rod 3 drives the screw nuts 8 on both sides to rotate.

[0018] A fan 16 is fixedly installed inside the chassis 14 , and the bottom of the chassis 14 penetrates into the interior of the chiller body 1 , and the chiller body 1 is cooled and dissipated by the fan 16 .

[0019] A transverse groove is provided at the bottom of the top plate 2, and a connecting block 9 is fixedly connected to the center of the bottom of the two lead screw nuts 8. The lower ends of the two connecting blocks 9 pass through the outside of the transverse groove and are respectively fixedly connected to the center of the top of the two brush plates 10. The lower ends of the two soft brushes 11 are respectively in contact with the top of the two filters 15. When the lead screw nut 8 moves horizontally with the rotation of the lead screw 7, the connecting block 9 at the bottom is driven to move the brush plate 10 at the bottom along the transverse groove.

At this time, the two screw nuts 8 move horizontally in the same direction with the rotation of the reciprocating screw 7. At this time, the screw nut 8 drives the brush plate 10 and the soft brush 11 at the bottom to move through the connecting block 9. The soft brush 11 moves back and forth on the filter 15 to sweep the dust on the filter 15 off.

[0022] In summary: the air-cooled chiller with dust-proof filter blockage is designed with a top plate 2, a transmission rod 3, a motor 4, a driven gear 5, a driving gear 6, a reciprocating screw 7, a screw nut 8, a brush plate 10 and a soft brush 11. The motor 4 drives the driving gear 6 and the driven gear 5 to rotate, thereby driving the reciprocating screw 7 at both ends of the transmission rod 3 to rotate. Through a threaded connection, the screw nut 8 drives the soft brush 11 under the brush plate 10 to move back and forth on the filter 15, so that the soft brush 11 can continuously clean the filter 15, effectively avoiding the problem of the filter 15 being blocked by dust, and can keep it clean and unobstructed, thereby improving the heat dissipation efficiency of the chiller and extending the service life of the chiller. At the same time, since the cleaning process is automatic and no human intervention is required, the maintenance cost and workload are greatly reduced, and the reliability and stability of the equipment are improved.
