Description

Technical Field

[0001] This utility model relates to the technical field of air condensation devices, and more specifically, to an air condensation device for a propylene refrigeration compressor unit. Background Technology

[0002] An air condenser unit condenses the refrigerant from a gaseous state to a liquid state through heat exchange between air and the refrigerant. In a propylene refrigeration compressor unit, the refrigerant is compressed into a high-temperature, high-pressure gaseous state, which then enters the air condenser unit. The cooling air inside the air condenser unit comes into contact with the high-temperature refrigerant, absorbs its heat, and cools it, causing it to condense into a liquid state. The heat released during the condensation process is carried away by the air and dissipated into the atmosphere through natural convection or forced ventilation.

[0003] When operating, the air condenser continuously draws in cool outside air to promote air circulation. To ensure the quality of the air entering the device, it is equipped with a filter to remove impurities. However, in actual use, the filter needs to be cleaned regularly due to the accumulation of dust and impurities. But to clean it, the operator must open the device's door to remove the filter. Since the device contains many electrical components, removing the filter can easily lead to accidental contact with these components, increasing the risk of electric shock. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 2-6 As shown, an air condensing device for a propylene refrigeration compressor unit includes a condensing box 1, a mounting plate 10, a filter screen 15, and a flexible snap-fit ​​assembly.

[0029] The top of the mounting plate 10 is provided with a sliding groove 11; the sliding groove 11 can be used to install the filter screen 15 and allow the filter screen 15 to slide horizontally along the inner wall of the sliding groove 11, thereby pulling the filter screen 15 out of the condenser box 1.

[0030] The filter screen 15 is slidably connected in the slide groove 11. The top of the filter screen 15 has a gripping hole 16. The corner of the filter screen 15 near the gripping hole 16 has an arc corner 17. The filter screen 15 extends to the outside of the condenser box 1 on the side of the gripping hole 16. The gripping hole 16 is designed so that the operator can easily insert his / her fingers into the gripping hole 16 to grip the filter screen 15 and make it easy to disassemble.

[0031] The elastic locking assembly includes a support block 18, which is fixedly installed on the outer wall of the condenser box 1. A slide rod 19 is fixedly connected to the side wall of the support block 18. A second spring 21 is sleeved on the outer wall of the slide rod 19. A limit ring 20 is fixedly connected to the outer wall of the slide rod 19. A slider 22 is slidably connected to the outer wall of the slide rod 19. A locking block 23 is fixedly connected to the top of the slider 22. The locking block 23 is used to lock the arc angle 17 on the filter screen 15. One end of the second spring 21 is fixedly connected to the slider 22, and the other end of the second spring 21 is fixedly connected to the support block 18. When removing the filter screen 15, the locking block 23 is pulled to both sides, causing the locking block 23 to drive the slider 22 to slide along the outer wall of the slide rod 19, so that the locking block 23 is released from the obstruction of the filter screen 15. The filter screen 15 is then pulled outward, and the filter screen 15 is pulled out of the condenser box 1, avoiding the need for the operator to open the box door 2 and disassemble it from inside the device, thus improving the safety of operation.

[0032] In this embodiment, as Figure 6 As shown, the locking block 23 includes a connecting part 24, a guiding part 25, and a locking part 26. The guiding part 25 has an inclined structure, and the locking part 26 is an arc-shaped groove. The setting of the guiding part 25 facilitates the filter screen 15 to press and contact with the guiding part 25, pushing the locking block 23 to slide along the outer wall of the slide rod 19, so that the two locking blocks 23 move in opposite directions. Thus, under the elastic force of the second spring 21, the locking block 23 automatically locks the filter screen 15.

[0033] In this embodiment, as Figure 5 As shown, limit grooves 12 are provided on both sides of the inner wall of the slide groove 11. An elastic plate 13 is slidably connected to the inner wall of the slide groove 11. Two first springs 14 are fixedly connected to the outer wall of the elastic plate 13. The ends of the first springs 14 are fixedly connected to the mounting plate 10. Under the elastic force of the first springs 14, the elastic plate 13 can elastically squeeze the filter screen 15. When the filter screen 15 filters impurities in the air, it is easy to shake under the action of airflow. However, the elastic force of the elastic plate 13 can reduce the shaking amplitude of the filter screen 15 and improve the stability of the filter screen 15.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, the outer wall of the condenser box 1 is hinged with a door 2, and air inlet nets 3 are fixedly connected to both sides of the condenser box 1. The air inlet nets 3 can provide safety protection for the condenser box 1, ensure the rapid entry of external air, and prevent mosquitoes from entering.

[0035] In this embodiment, as Figure 1 and Figure 2As shown, an air inlet pipe 6 and an exhaust pipe 7 are fixedly connected to the side wall of the condenser box 1, respectively. The ends of the air inlet pipe 6 and the exhaust pipe 7 extend into the interior of the condenser box 1. A condenser pipe 4 is fixedly connected to one end of the air inlet pipe 6 and the exhaust pipe 7 inside the condenser box 1. Multiple heat sinks 5 are fixedly connected to the outer wall of the condenser pipe 4. A fan 9 is fixedly connected to the inner wall of the condenser box 1. The air inlet of the fan 9 is close to the filter screen 15, and the exhaust port of the fan 9 extends to the outside of the condenser box 1. The heat sinks 5 can increase the contact area between the condenser pipe 4 and the air, thereby improving the heat dissipation efficiency.

[0036] In this embodiment, as Figure 2 As shown, two frequency converters 8 are fixedly connected to the top of the mounting plate 10; traditional fans are usually driven by fixed frequency motors, which cannot adjust the speed according to actual needs, resulting in high energy consumption and limited heat dissipation efficiency. In order to optimize energy consumption and heat dissipation performance, the system is upgraded to a fan driven by frequency converters, and the heat dissipation needs under different working conditions are matched by adjusting the motor speed.

[0037] However, operating a single frequency converter carries potential risks. If the frequency converter fails, it will directly affect the operation of the fan. To address this, an additional frequency converter of the same specifications is added as a hot standby. At the same time, a PLC control system is added for seamless switching and control. The PLC is connected to the two frequency converters via hard wiring. During normal operation, one of the frequency converters controls the operation of the fan. If the operating frequency converter fails, the other frequency converter can be quickly switched over and take over the control of the fan, thus avoiding the shutdown of the plant or damage to the equipment due to the failure of one frequency converter.

[0038] Working principle: When the fan 9 is running, the outside air enters the condenser box 1 through the air inlet net 3 and flows rapidly from bottom to top to cool the heat sink 5 and condenser pipe 4. The air is filtered by the filter net 15 to remove impurities. The filtered air enters the fan 9 and is discharged to the outside of the condenser box 1 by the fan 9.

[0039] When disassembling the filter screen 15, pull the locking blocks 23 to both sides, so that the locking blocks 23 drive the slider 22 to slide along the outer wall of the slide rod 19, so that the locking blocks 23 can disengage from the filter screen 15.

[0040] Under the elastic force of the second spring 21, the elastic plate 13 pushes the filter screen 15 to slide along the slide groove 11 to the outside of the condenser box 1;

[0041] The operator holds the inside of the holding hole 16 and pulls the filter screen 15 outward to remove the filter screen 15 from the inside of the condenser box 1.

[0042] During installation, the corner of the filter screen 15 presses against the two locking blocks 23, inserting the filter screen 15 into the groove 11 on the mounting plate 10. The filter screen 15 presses against the elastic plate 13, compressing the second spring 21. Under the elastic force of the first spring 14, the locking blocks 23 engage with the arc corner 17 on the filter screen 15, thereby quickly installing the filter screen 15.

[0043] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0044] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
