Description

Technical Field

[0001] This utility model relates to the field of air drying technology, and in particular to an air dryer. Background Technology

[0002] An air dryer is a device that removes or reduces moisture from the air. It is often used in humid environments or environments with requirements for air humidity to meet production and living needs. There are two common types of air dryers: condensing and adsorption. Condensing dryers mainly use heat exchange to condense water vapor in the air into water, which is then collected and removed. Adsorption dryers mainly use an adsorption material to deliver the air to be dried, allowing the adsorption material to adsorb water vapor in the air to achieve the purpose of drying the air. This article discusses condensing dryers. Common condensing dryers have a short airflow distance, which cannot fully contact the evaporator tube, resulting in insufficient condensation effect. Therefore, an air dryer is needed.

[0003] In existing air dryer devices, when air is input into the air dryer, it comes into contact with the evaporator tube and then directly passes through the condenser tube to regain its temperature. The evaporator tube and the condenser tube are close together, and the air residence time is short, which prevents sufficient contact between the air and the evaporator tube for condensation. In addition, the cold air after passing through the evaporator tube is directly discharged, resulting in low resource utilization. Utility Model Content

[0004] The purpose of this invention is to provide an air dryer to solve the problems mentioned in the background art of existing air dryer devices. When air is input into the air dryer and comes into contact with the evaporator, it directly returns to its original temperature through the condenser. The evaporator and condenser are close together, the air residence time is short, and it is not possible to fully contact the evaporator for condensation. Furthermore, the cold air after passing through the evaporator is directly discharged, resulting in low resource utilization.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air dryer, comprising a shell, an air inlet on the upper half of one side of the shell, an air outlet on the upper half of the other side of the shell, a first support plate fixedly installed on the inner ring of the shell, an air intake fan fixedly installed on one side of the upper surface of the inner ring of the shell, a first heat-conducting fin assembly fixedly installed on the inner ring of the shell, an evaporator tube being installed through the interior of the first heat-conducting fin assembly, a second support plate fixedly installed on the inner ring of the shell, support strips fixedly installed on both sides of the inner ring of the shell, a condenser tube being fixedly installed through an opening at one end of the support strip, a third heat-conducting fin assembly sleeved on the outer ring of the condenser tube, a capillary tube fixedly connected to one end of the condenser tube, a third support plate fixedly installed below the second support plate, and an air outlet fan fixedly installed on the other side of the upper surface of the inner ring of the shell.

[0006] Preferably, the first heat-conducting sheet group is connected through a first support plate and a second support plate, and is snapped into a slot of a third support plate.

[0007] Preferably, a copper plate is fixedly installed on the inner ring of the outer shell, and a second heat-conducting fin group is fixedly installed on one side of the copper plate. The copper plate and the second support plate are connected by bolts.

[0008] Preferably, the outer ring of the condenser tube is fitted with a rubber sleeve, and the groove of the rubber sleeve is engaged with one corner of the copper plate.

[0009] Preferably, the upper surfaces of the first support plate and the second support plate are provided with inclined first water collection grooves, and the upper surface of the third support plate is provided with a second water collection groove, one end of which converges at the through hole in the third support plate.

[0010] Preferably, a water tank is placed on the inner bottom surface of the outer shell, and the water tank has an open structure with an opening at the top.

[0011] Preferably, a compressor is placed on the inner bottom surface of the outer casing, a refrigerant outlet pipe is fixedly connected to the upper air outlet of the compressor, and a refrigerant inlet pipe is fixedly connected to the upper air inlet of the compressor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This air dryer device, through the arrangement of an air inlet, an air outlet, a first support plate, an air intake fan, a first heat-conducting fin group, a copper plate, a second support plate, a first water collection tank, a second heat-conducting fin group, a third support plate, a second water collection tank, an exhaust fan, and a water tank, allows air to be drawn in through the air inlet by the air intake fan. The air then comes into contact with the first heat-conducting fin group, which has been cooled by the evaporation tube. The water vapor in the air condenses upon contact with the cold air, forming water droplets, which then flow into the water tank along the first and second water collection tanks and are collected. At the same time, the curved chamber formed by the first, second, and third support plates increases the contact time between the air and the evaporation tube, allowing for better condensation. Furthermore, the air, after three condensations, becomes cold and dry. When it is discharged, it comes into contact with the copper plate and the second heat-conducting fin group, cooling the copper plate and the second heat-conducting fin group. This also cools and condenses the water vapor in the air drawn in by the air intake fan, increasing the utilization effect of the cold air. Finally, the dried air is discharged through the air outlet by the exhaust fan. Attached Figure Description

[0021] Furthermore, the first heat-conducting plate group 6 is connected through the first support plate 4 and the second support plate 10, and is snapped into the slot of the third support plate 18. Through the arrangement of the first heat-conducting plate group 6, the first support plate 4, the second support plate 10 and the third support plate 18, the first heat-conducting plate group 6 can be better fixed during use. At the same time, the first support plate 4, the second support plate 10 and the third support plate 18 can form a curved chamber, which can increase the contact time between the air and the first heat-conducting plate group 6 and increase the condensation effect.

[0022] Furthermore, a copper plate 8 is fixedly installed on the inner ring of the outer shell 1, and a second heat-conducting sheet group 9 is fixedly installed on one side of the copper plate 8. The copper plate 8 and the second support plate 10 are locked together by bolts 12. Through the arrangement of the copper plate 8, the second heat-conducting sheet group 9, the second support plate 10 and the bolts 12, the copper plate 8 and the second support plate 10 can be fixed during use.

[0023] Furthermore, a rubber sleeve 16 is fitted around the outer ring of the condenser tube 14. The groove of the rubber sleeve 16 is engaged with one corner of the copper plate 8. Through the arrangement of the condenser tube 14, the rubber sleeve 16 and the copper plate 8, the condenser tube 14 can be fixed and protected during use, while the copper plate 8 can be sealed.

[0024] Furthermore, the upper surfaces of the first support plate 4 and the second support plate 10 are both provided with inclined first water collection tanks 11, and the upper surface of the third support plate 18 is provided with a second water collection tank 19. One end of the second water collection tank 19 converges at the through hole opened in the third support plate 18. Through the arrangement of the first water collection tank 11, the second water collection tank 19 and the third support plate 18, the collection of condensate can be realized.

[0025] Furthermore, a water tank 21 is placed on the inner bottom surface of the outer casing 1. The water tank 21 is an open structure with an opening at the top. Through the arrangement of the water tank 21 and the third support plate 18, condensate can be collected and flow into the water tank 21 to achieve the purpose of collection and removal.

[0026] Furthermore, a compressor 22 is placed on the inner bottom surface of the outer casing 1. A condensate outlet pipe 24 is fixedly connected to the upper air outlet of the compressor 22, and a condensate inlet pipe 23 is fixedly connected to the upper air inlet of the compressor 22. Through the arrangement of the compressor 22, the condensate outlet pipe 24 and the condensate inlet pipe 23, the condensate can be compressed, and the purpose of condensate output and recovery can be achieved at the same time.

[0027] Working principle: First, place the air dryer in the environment where the air needs to be dried, and power on the compressor 22. The compressor 22 starts working, pressurizing the gaseous refrigerant, which is then fed into the condenser tube 14. The gaseous refrigerant condenses and releases heat in the condenser tube 14, heating the third heat-conducting fin group 15. At the same time, the exhaust fan 20 runs to cool the condenser tube 14. The liquid refrigerant is depressurized through the capillary tube 17 and enters the evaporator tube 7. The liquid refrigerant evaporates and absorbs heat in the evaporator tube 7, cooling the first heat-conducting fin group 6. The intake fan 5 is turned on, and air is drawn in through the air inlet 2 and flows through the curved chamber formed by the first support plate 4, the second support plate 10, and the third support plate 18. The water vapor in the air comes into contact with the cold first heat-conducting fin group 6. The plate group 6 generates condensation, producing water droplets. These droplets flow into the water tank 21 along the first water collection tank 11 and the second water collection tank 19 and are collected. The curved chamber increases the condensation time and number of times the air is condensed. When the dry and cold air, which has been condensed three times, flows through the chamber composed of the copper plate 8 and the outer shell 1, it cools the copper plate 8. The copper plate 8 conducts heat, which also cools the second heat-conducting plate group 9. At this time, the copper plate 8 and the second heat-conducting plate group 9 also have the function of cooling and condensing the air drawn in by the intake fan 5, improving the utilization rate of the dry and cold air. Finally, under the action of the exhaust fan 20, the dry and cold air flows through the third heat-conducting plate group 15, which cools the condenser tube 14 and also reheats itself. Then it is discharged through the air outlet 3, ultimately achieving the purpose of drying the air.
