Description

Technical Field

[0001] This utility model relates to the field of compressed air dryer technology, specifically a compressed air dryer with a vertical cooling and dehumidification device. Background Technology

[0002] Compressed air dryers are machines that dry compressed air. They can be divided into two types: refrigerated compressed air dryers and adsorption compressed air dryers. Compressed air dryers use a circulating refrigerant to cool the air and then use the refrigerant to absorb heat from the compressed high-temperature air. This allows the moisture in the air to condense and drip down during cooling, thus achieving the effect of cooling and dehumidification.

[0003] Currently, refrigerated compressed air dryers typically cool and dehumidify compressed high-temperature air in the evaporator. The refrigerant enters the evaporator through the refrigeration pipes, and the compressed high-temperature air comes into contact with the refrigeration pipes inside the evaporator and is cooled and dehumidified. However, in low-temperature environments such as winter, the cooling water in the evaporator is prone to freezing, which can lead to pipe blockage and affect the cooling effect. Utility Model Content

[0004] The purpose of this invention is to provide a compressed air dryer with a vertical cooling and dehumidification device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compressed air dryer with a vertical cooling and dehumidification device, comprising a compressed air dryer body, a scroll compressor and an evaporator for assembling the compressed air dryer body, and further comprising: A ventilation pipe is connected to the top of the evaporator, and a drain pipe and an air inlet pipe are respectively connected to both sides of the evaporator surface. A zero-air-loss drainer is installed on the surface of the drain pipe. A heat exchange mechanism is located inside the lower part of the evaporator. An upper disc and a lower disc are fixedly connected to the upper and lower parts of the inner wall of the evaporator, respectively. A cooling mechanism is installed between the lower disc and the upper disc. A rotating shaft is rotatably connected to the upper part of the inner wall of the evaporator. The surface of the rotating shaft is fixedly fitted with blades, and the top of the upper disc is equipped with an ice-breaking mechanism that can reciprocate and move up and down.

[0006] Preferably, the heat exchange mechanism includes a heat exchange frame embedded in the bottom of the inner wall of the evaporator, the inner wall of the heat exchange frame is surrounded by a plurality of bends, the air inlet pipe is connected to the heat exchange frame, and the bottom of the evaporator is provided with a slot connected to the heat exchange frame for discharging cooling water.

[0007] Preferably, the cooling mechanism includes a refrigeration pipe that is fixedly inserted through the evaporator, a sleeve is fitted on the surface of the refrigeration pipe, and a blower pipe and a ventilation duct are respectively connected to the top and bottom of the sleeve. The ventilation duct is fixedly inserted through the lower disc, and the blower pipe is fixedly inserted through the upper disc.

[0008] Preferably, the ice-breaking mechanism includes a lifting frame that slides through both sides of the top of the upper disc, cams are fixedly sleeved on both sides of the rotating shaft surface, a fixed frame is fixedly connected to the bottom of the lifting frame, and a plurality of ice-breaking rods are fixedly connected to the bottom of the fixed frame.

[0009] Preferably, the top and bottom of the inner wall of the lifting frame are provided with grooves, and the surface of the cam is in contact with the inner wall of the groove.

[0010] Preferably, the bottom of the ice-breaking rod is tapered.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a heat exchange mechanism to receive cooling water. High-temperature air enters the heat exchange frame, and the cooling water pre-cools the air. Conversely, the high-temperature air reduces the possibility of the cooling water freezing. The high-temperature air flows upward and is cooled and dehumidified by the cooling mechanism. As the treated air is discharged, it drives the ice-breaking mechanism to move back and forth, which not only prevents the cooling water from freezing but also breaks up any frozen cooling water. This solves the problem that some compressed air dryers freeze their internal cooling water in low-temperature environments, which can affect normal drainage and cooling effect.

[0014] 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.

[0015] Please see Figure 1-6As shown, a compressed air dryer with a vertical cooling and dehumidification device includes a compressed air dryer body 1, a scroll compressor 2, and an evaporator 3, which are used to assemble the compressed air dryer body 1. The scroll compressor 2 compresses gas, and the compressed gas, after being cooled, is discharged into the interior of the evaporator 3, thereby cooling and drying the compressed high-temperature air inside the evaporator 3. Water vapor in the air condenses and drips down and collects. A ventilation pipe 5 is connected to the top of the evaporator 3, and a drain pipe 13 and an air inlet pipe 4 are connected to both sides of the surface of the evaporator 3, respectively. The air inlet pipe 4 is used to inject compressed high-temperature air into the interior of the evaporator 3. The cooled and dried air is discharged through the ventilation pipe 5, and the cooling water is discharged through the drain pipe 13. A zero-loss drainer 14 is installed on the surface of the drain pipe 13, achieving the effect of draining water without venting it. A heat exchange mechanism 6 is located at the bottom inside the evaporator 3. The heat exchange mechanism 6 includes a heat exchange frame 61 embedded in the bottom of the inner wall of the evaporator 3. Several bends 62 are arranged around the inner wall of the heat exchange frame 61. The air inlet pipe 4 is connected to the heat exchange frame 61. The heat exchange frame 61 can be used to collect cooling water. The compressed high-temperature air to be processed is discharged into the interior of the heat exchange frame 61 through the air inlet pipe 4. At this time, the cooling water can... The high-temperature air is pre-cooled. The bottom of the evaporator 3 has a slot 63 connected to the heat exchange frame 61. The slot 63 is used to discharge cooling water. The cooling water generated after the air pre-cooling treatment is discharged into the drain pipe 13 through the slot 63. Simultaneously, the temperature of the pre-treated high-temperature air decreases accordingly and is discharged through the bend pipe 62. Thus, the heat exchange mechanism 6, in conjunction with the cooling water inside the evaporator 3, can pre-treat the high-temperature air. An upper disc 9 and a lower disc 8 are fixedly connected to the upper and lower sides of the inner wall of the evaporator 3, respectively. A cooling mechanism 7 is installed between the lower disc 8 and the upper disc 9. The cooling mechanism 7 is used to cool the air after the air has been pre-treated. The pretreated air undergoes further cooling and dehumidification. The cooling mechanism 7 includes a refrigeration pipe 71 that is fixedly inserted through the evaporator 3. The refrigeration pipe 71 is used to transport the refrigerant. The two ends of the refrigeration pipe 71 are respectively connected to the expansion valve and the gas-liquid separator. The expansion valve and the gas-liquid separator are components of the main body 1 of the compressed air dryer. They are existing mature technologies and are well known to those skilled in the art, so they will not be described in detail here. The surface of the refrigeration pipe 71 is fitted with a sleeve 72. The top and bottom of the sleeve 72 are respectively connected to the air blowing pipe 74 and the ventilation duct 73. The ventilation duct 73 is fixedly inserted through the lower disc 8, and the air blowing pipe 74 is fixedly inserted through the upper disc 9.

[0016] Pre-treated high-temperature air is discharged into the interior of the sleeve 72 through the ventilation duct 73. The refrigerant inside the refrigeration pipe 71 absorbs heat from the air, lowering the air temperature. Moisture in the air condenses and drips downwards through the sleeve 72 and ventilation duct 73, preparing for subsequent pre-treatment of high-temperature air. The cooled and dried air is then conveyed upwards through the blower pipe 74. A rotating shaft 10 is rotatably connected to the upper part of the inner wall of the evaporator 3. Blades 11 are fixedly fitted onto the surface of the rotating shaft 10. An ice-breaking mechanism 12 that can reciprocate and move vertically is installed on the top of the upper disc 9. The ice-breaking mechanism 12 includes a lifting frame 122 that slides through both sides of the top of the upper disc 9. The surface of the rotating shaft 10... Cams 121 are fixedly fitted on both sides of the lifting frame 122. Grooves are provided on the top and bottom of the inner wall of the lifting frame 122. The surface of the cam 121 contacts the inner wall of the groove. A fixed frame 123 is fixedly connected to the bottom of the lifting frame 122. Several ice-breaking rods 124 are fixedly connected to the bottom of the fixed frame 123. The bottom of the ice-breaking rods 124 is conical. When the upper disc 9 rotates, the blades 11 rotate and cooperate with the groove, which can drive the lifting frame 122 to move up and down. The fixed frame 123 then drives the ice-breaking rods 124 to move up and down, which can knock the cooling water that is frozen in the heat exchange frame 61 to help it thaw and be discharged through the drain pipe 13.

[0017] Working principle: Compressed high-temperature air is injected into the heat exchange frame 61 through the air inlet pipe 4. The cooling water collected in the heat exchange frame 61 pre-treats the high-temperature air. The pre-treated high-temperature air is discharged into the evaporator 3 through the bend pipe 62. The air accumulates in the evaporator 3 and is discharged into the sleeve 72 through the ventilation duct 73. The high-temperature air comes into contact with the surface of the refrigeration pipe 71. The refrigerant inside the refrigeration pipe 71 absorbs the heat from the air, and the moisture in the air condenses and drips downwards. The heat exchange frame 61 collects the cooling water for subsequent use. The cooled and dehumidified air is discharged through the blower pipe 74. The airflow causes the blades 11 to rotate. At this time, the shaft 10 rotates along with the blades 11, causing the cam 121 to rotate. The lifting frame 122 moves up and down repeatedly. The ice-breaking rod 124 moves up and down to prevent the cooling water from being stagnant and reduce the possibility of the cooling water freezing. If the cooling water freezes due to low temperature, the knocking of the ice-breaking rod 124 and the temperature of the injected air can facilitate thawing so that the cooling water can be discharged normally. The discharged cooling water is discharged through the cooperation of the drain pipe 13 and the zero-air-loss drainer 14. The air that has been cooled and dried is discharged through the ventilation pipe 5.
