Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically a refrigerated dryer. Background Technology

[0002] A refrigerated dryer is a device that dries compressed air. It utilizes the characteristic that "air's ability to hold water vapor decreases as temperature decreases" to cool compressed air below the dew point temperature, causing water vapor to condense into water droplets, which are then discharged through a separator, ultimately resulting in dry compressed air.

[0003] Most refrigerated dryers currently require air intake during operation. Since the air contains dust particles, filter plates are typically used to filter the dust. However, these filter plates are prone to clogging over time, requiring cleaning. During cleaning, the dust can easily drift into the machine's interior, affecting internal components. Furthermore, most refrigerated dryers are bulky, inconvenient to move, and difficult to use in daily life. To address these issues, the inventor proposes a refrigerated dryer to solve these problems. Utility Model Content

[0019] 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.

[0020] Example: Figure 1-5 As shown, this utility model provides a refrigerated dryer, including a body 1. Movable frames 2 are slidably installed on the upper inner sides of both sides of the body 1. The body 1 contains a compressor, an air-cooled condenser, an expansion valve, an evaporator, a precooler, a gas-liquid separator, an automatic drain, and a refrigeration system. In operation, high-temperature compressed air first enters the precooler to exchange heat with the dried, low-temperature air, achieving initial cooling. Then, it enters the evaporator to exchange heat with the low-temperature refrigerant, being cooled to the dew point temperature. At this point, water vapor in the air condenses into liquid droplets or mist because its temperature is below the saturation point. Next, the compressor compresses the refrigerant into a high-temperature, high-pressure gas, which enters the air-cooled condenser for heat dissipation. The refrigerant is condensed into a liquid state by air cooling, releasing heat. At this time, a fan draws in air, and the drawn air passes through a filter plate to filter out dust. The condensed air then enters the gas-liquid separator, where it is further cooled by centrifugal force... Liquid water is separated by methods such as baffle interception. The separated dry air absorbs heat and rises in temperature through a precooler before being output to the air-using end. This is used to install brush 21 and drive brush 21 to move back and forth to clean the filter plate. Brush 21 is fixedly installed on the lower surface of both movable frames 2, and the bristles on the side of brush 21 that is far away from each other are in contact with the filter plate. Baffles 3 are rotatably installed on both sides of the machine body 1 to seal the air inlet and prevent dust from being scattered into the machine body 1 when cleaning the filter plate. Baffles 3 are also used to seal the air inlets on both sides of the machine body 1. Two movable columns 4 are slidably installed on both sides of the machine body 1 to install casters 41 and drive casters 41 to move so that casters 41 are in contact with the ground for easy movement of the machine body 1. Casters 41 can be detachably installed at the bottom of all four movable columns 4, and the bottom of casters 41 are in contact with the ground.

[0021] Worm gears 31 are fixedly installed on the outer surface of one end of each of the two baffles 3. A worm 18 is rotatably installed on the side of the body 1, and the worm threads at both ends of the worm 18 are in opposite directions. The worm 18 meshes with the two worm gears 31 to drive the baffles 3 to rotate. In use, rotating the worm 18 drives the worm gears 31 to rotate, and the rotation of the worm gears 31 drives the baffles 3 to rotate, so that the baffles 3 seal the air inlet.

[0022] By adopting the above technical solution, the worm gear 18 can drive the baffle 3 to rotate.

[0023] A No. 3 motor 19 is fixedly installed on the side of the machine body 1, and the output shaft of the No. 3 motor 19 is fixedly connected to the worm gear 18 to drive the worm gear 18 to rotate. When in use, the No. 3 motor 19 is turned on to drive the worm gear 18 to rotate.

[0024] By adopting the above technical solution, the No. 3 motor 19 can drive the worm gear 18 to rotate.

[0025] Both sides of the machine body 1 are rotatably mounted with drive screws 13, and each of the four drive screws 13 is threaded with a movable column 4 to drive the movable column 4 to move. In use, the movable column 4 is driven to move by the rotation of the drive screws 13.

[0026] By adopting the above technical solution, the drive screw 13 can drive the moving column 4 to move.

[0027] Each of the four drive screws 13 has a second bevel gear 14 fixedly mounted at its top. A crossbar 11 is rotatably mounted on the inner top of both sides of the machine body 1. The two crossbars 11 are driven by a synchronous pulley and a synchronous belt. A first bevel gear 12 is fixedly mounted at both ends of the two crossbars 11. The first bevel gear 12 and the second bevel gear 14 mesh with each other to drive the drive screws 13 to rotate. In use, the rotation of the crossbars 11 drives the first bevel gear 12 to rotate, the rotation of the first bevel gear 12 drives the second bevel gear 14 to rotate, and the rotation of the second bevel gear 14 drives the drive screws 13 to rotate.

[0028] By adopting the above technical solution, the crossbar 11 can drive the drive screw 13 to rotate.

[0029] A No. 1 motor 15 is fixedly installed on the upper part of the side of the machine body 1 away from the worm gear 18, and the output shaft of the No. 1 motor 15 is fixedly connected to the crossbar 11 to drive the crossbar 11 to rotate. When in use, the No. 1 motor 15 is turned on to drive the crossbar 11 to rotate.

[0030] By adopting the above technical solution, the No. 1 motor 15 can drive the crossbar 11 to rotate.

[0031] Mounting rods 16 are rotatably mounted on the upper parts of both sides of the body 1. Rotating plates 161 are fixedly mounted on the ends of the two mounting rods 16 that are close to each other. Guide rods 162 are fixedly mounted on the top ends of the two rotating plates 161 that are close to each other. The ends of the two guide rods 162 that are close to each other are slidably inserted into the moving frame 2 for moving the moving frame 2. In use, the rotation of the mounting rods 16 drives the rotating plates 161 to rotate, and the rotation of the rotating plates 161 drives the guide rods 162 to make circular motion. At this time, the circular motion can be decomposed into horizontal movement and vertical movement. When the guide rods 162 move horizontally, they are slidably set inside the moving frame 2. When the guide rods 162 move vertically, they drive the moving frame 2 to move vertically.

[0032] By adopting the above technical solution, the mounting rod 16 can drive the movable frame 2 to move.

[0033] A rotating rod 17 is rotatably mounted on the side of the machine body 1 near the worm gear 18, and the two ends of the rotating rod 17 are respectively connected to two mounting rods 16 via synchronous pulleys and synchronous belts. A second motor 171 is fixedly mounted on the side of the machine body 1 near the third motor 19, and the output shaft of the second motor 171 is fixedly connected to the rotating rod 17 to drive the mounting rods 16 to rotate. In use, the second motor 171 is turned on to drive the rotating rod 17 to rotate, and the rotation of the rotating rod 17 drives the mounting rods 16 to rotate.

[0034] By adopting the above technical solution, the rotating rod 17 can drive the mounting rod 16 to rotate.

[0035] Working principle: First, when it is necessary to clean the filter plate, turn off the device and turn on motor 19 to drive worm gear 18 to rotate. Worm gear 18 drives worm wheel 31 to rotate. The rotation of worm wheel 31 drives baffle 3 to rotate, so that baffle 3 seals the air inlet.

[0036] Next, turn on motor 171 to drive the rotating rod 17 to rotate. The rotation of the rotating rod 17 drives the mounting rod 16 to rotate. The rotation of the mounting rod 16 drives the rotating plate 161 to rotate. The rotation of the rotating plate 161 drives the guide rod 162 to make a circular motion, thereby driving the moving frame 2 to move vertically back and forth. The movement of the moving frame 2 drives the brush 21 to move back and forth to clean the filter plate.

[0037] When the device needs to be moved, the first motor 15 is turned on to drive the crossbar 11 to rotate. The rotation of the crossbar 11 drives the first bevel gear 12 to rotate. The rotation of the first bevel gear 12 drives the second bevel gear 14 to rotate. The rotation of the second bevel gear 14 drives the drive screw 13 to rotate. The rotation of the drive screw 13 drives the moving column 4 to move. The movement of the moving column 4 drives the universal wheel 41 to move, so that the universal wheel 41 contacts the ground.

[0038] Finally, push the machine body 1 to move it, so that the position of the machine body 1 can be adjusted. After the adjustment is completed, turn on the first motor 15 to drive the universal wheel 41 to move upward, so that the universal wheel 41 is separated from the ground, so as to prevent the machine body 1 from moving during use.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
