Ice water passes through a serpentine pipe and is clamped by a suction fan to cool and dissipate heat in the box body, an exhaust fan is mounted on a second through hole to extract air in the box body and exhaust the air through an air outlet pipe, so that air circulation in the box body is accelerated, and two groups of elliptical blocks circularly rotate to continuously extrude a filter plate to generate vibration; dust on the filter plate is conveniently vibrated to fall into a collecting box through a dust discharging opening, and the collecting box slides between the two sets of supporting blocks, so that the collecting box is conveniently detached, and the collected dust is cleaned; therefore, the problems that a traditional air-cooled screw type water chilling unit is low in heat dissipation efficiency, and the air exhaust effect is reduced due to the fact that dust is prone to adhering to a filter plate after long-time use are effectively solved.

Description

Technical Field

[0001] The utility model relates to the technical field of screw-type chillers, in particular to an air-cooled screw-type chiller. Background Art

[0002] Screw refrigeration compressor, as an indispensable and important equipment in refrigeration and air-conditioning systems, has a unique working principle and a wide range of applications. With its high efficiency, stability, reliability, durability, easy operation and maintenance, and strong adaptability, screw refrigeration compressor occupies an important position in the refrigeration industry. The unit has exquisite design, compact structure, stable operation, simple operation and continuously adjustable cooling capacity, and has excellent space utilization. However, when the core components inside the unit, such as the condenser, oil separator and screw compressor, are operating efficiently, a large amount of heat energy will be generated. If this heat cannot be effectively dissipated, it will directly cause the equipment to overheat, thereby reducing its operating efficiency and shortening its service life. Traditional air-cooled screw chillers have low heat dissipation efficiency and after long-term use, dust is easily adhered to the filter plate, resulting in reduced exhaust effect. Therefore, there are certain disadvantages.

[0003] In summary, the utility model solves the existing problems by designing an air-cooled screw chiller. Utility Model Content

The inner side of the air outlet pipe 7 is narrow Limit blocks 16 are installed at both ends of the top and bottom of both side walls, and a fixing plate 17 is installed at one end of the narrower inner side walls of the air outlet pipe 7. Return springs 18 are installed at both ends of the top and bottom of the outer side of the fixing plate 17. A filter plate 19 is installed at one end of the return spring 18 and located inside the air outlet pipe 7. A rotating rod 20 is installed between the narrower inner side walls of the air outlet pipe 7, and elliptical blocks 21 are symmetrically installed at both ends of the outer side of the rotating rod 20. Support blocks 22 are symmetrically installed at both ends of the bottom of the air outlet pipe 7, and slide grooves 2201 are symmetrically opened on the outer surface of the support blocks 22. A collecting box 23 is installed at the bottom of the air outlet pipe 7 and located between the two support blocks 22.

[0030] Specifically, refer to Figure 3 The end of the first connecting pipe 5 away from the water pump 4 passes through the interior of the box 1 and is connected to one end of the serpentine pipe 9, and the end of the second connecting pipe 6 away from the water tank 3 passes through the interior of the box 1 and is connected to the other end of the serpentine pipe 9, thereby ensuring that the ice water inside the water tank 3 is extracted by the water pump 4 through the first connecting pipe 5 to the interior of the serpentine pipe 9 and then returns to the interior of the water tank 3 through the second connecting pipe 6. The ice water passes through the serpentine pipe 9 and cools the interior of the box 1 under the support of the suction fan 8.

[0031] Furthermore, the suction fan 8 is installed on the first through hole 101 to draw external air through the filter 2, and the exhaust fan 14 is installed on the second through hole 102 to draw air inside the box 1 and discharge it through the air outlet pipe 7, thereby accelerating the air circulation inside the box 1 and accelerating the heat dissipation effect inside the box 1.

[0032] Furthermore, limiting grooves are provided at the top and bottom of both ends of the outside of the filter plate 19, and the limiting grooves on the outside of the filter plate 19 are slidably connected to the corresponding limiting blocks 16, thereby ensuring that the stability of the movement of the filter plate 19 squeezed by the elliptical block 21 inside the air outlet pipe 7 is increased by sliding the filter plate 19 on the four groups of limiting blocks 16.

[0033] Furthermore, sliders are provided at both ends of the outside of the collection box 23, which are respectively slidably connected to the slide grooves 2201 on the support blocks 22, and the collection box 23 is located directly below the dust discharge port 701, thereby ensuring that the collection box 23 slides between the two groups of support blocks 22 to facilitate the disassembly of the collection box 23 and the cleaning of the collected dust.

[0034] For details, please refer to Figure 6 and Figure 7 One end of the rotating rod 20 passes through the outside of the air outlet pipe 7 and is connected to the output end of the driving motor 15, and the end of the rotating rod 20 away from the driving motor 15 is rotatably connected to the other side wall inside the air outlet pipe 7, thereby ensuring that the driving motor 15 drives the rotating rod 20 to rotate and drives the two elliptical blocks 21 to rotate, thereby squeezing the filter plate 19 to slide inside the air outlet pipe 7 and squeeze the four groups of return springs 18. The two groups of elliptical blocks 21 circulate and rotate continuously to squeeze the filter plate 19 to cause it to vibrate, so that the dust on the filter plate 19 is vibrated and dropped through the ash discharge port 701 to the inside of the collection box 23.

[0035] The working process of the present utility model: an air-cooled screw chiller designed by the present invention is used. During the use of the device, the water pump 4 draws the ice water inside the water tank 3 through the first connecting pipe 5 to the inside of the serpentine pipe 9 and then returns to the inside of the water tank 3 through the second connecting pipe 6. The ice water passes through the serpentine pipe 9 and cools the inside of the box 1 with the help of the suction fan 8. The suction fan 8 is installed on the first through hole 101 to draw external air through the filter 2, and the exhaust fan 14 is installed on the second through hole 102 to draw the air inside the box 1 and discharge it through the air outlet pipe 7, so as to speed up the air circulation inside the box 1 and speed up the heat dissipation effect inside the box 1. After a long period of heat dissipation, dust will stick to the filter plate 19, which will reduce the exhaust efficiency of the exhaust fan 14. By driving the motor 15 drives the rotating rod 20 to rotate and drives the two elliptical blocks 21 to rotate, thereby squeezing the filter plate 19 to slide inside the air outlet 7 and squeezing the four sets of return springs 18. The two sets of elliptical blocks 21 circulate and rotate continuously to squeeze the filter plate 19 to make it vibrate, which is convenient for vibrating the dust on the filter plate 19 and dropping it through the ash discharge port 701 to the inside of the collection box 23. The sliding of the filter plate 19 on the four sets of limit blocks 16 increases the stability of the elliptical blocks 21 squeezing the filter plate 19 to move inside the air outlet 7. The collection box 23 slides between the two sets of support blocks 22 to facilitate the disassembly of the collection box 23 to clean the collected dust, thereby increasing the heat dissipation effect of the condenser 11, the oil separator 12, and the screw compressor 13, and can collect the cleaned dust to increase the neatness of the device.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
