Description

Technical Field

[0001] This utility model relates to the field of refrigerated dryer technology, specifically a refrigerated dryer with an anti-clogging filter. Background Technology

[0002] A refrigerated air dryer is short for a freeze dryer. It is an air source processing element in a pneumatic system, mainly used to process compressed air. By cooling it down, it condenses the water vapor in the compressed air into liquid droplets. Its main components include a refrigeration compressor, a condenser, an evaporator, and an expansion valve. The refrigeration compressor is the heart of the refrigeration system. The condenser's function is to cool the high-pressure, superheated refrigerant vapor discharged from the refrigerant compressor into liquid refrigerant. The evaporator is the main heat exchange component of the refrigerated air dryer, and the expansion valve is the throttling mechanism of the refrigeration system.

[0003] According to patent announcement CN220460278U, a refrigerated dryer is described. This patent includes a refrigerated dryer body, an internally fixedly installed condenser, a dust removal component fixedly connected to the surface of the condenser, a drain valve penetrating the side of the refrigerated dryer body, a side cover fixedly connected to the inner wall of the refrigerated dryer body, a fan fixedly connected to the surface of the side cover, and a purification component fixedly connected to the surface of the fan. This refrigerated dryer, through the dust removal component, allows for easy cleaning of the condenser surface by simply opening the side cover and tightening the nut. Because the sliding ring is internally slidably connected to the fixed column, and the side of the brush is symmetrically fixedly connected to the sliding ring, the brush is pushed up and down to remove dust from the condenser surface. This prevents excessive dust from reducing the refrigeration effect of the condenser and improves the refrigerant compression efficiency.

[0004] However, while the dust on the condenser surface can be cleaned using the dust removal components during the use of the aforementioned patent, the ventilation holes on the side panel surface are not dustproofed. As a result, dust from the outside air enters the refrigerated dryer in large quantities through the ventilation holes when the dryer is dissipating heat. This causes a large amount of dust to accumulate on the outer walls of other components inside the dryer, which may clog critical components such as the expansion valve and compressor, leading to equipment failure or performance degradation, and thus affecting the use of the refrigerated dryer.

[0005] The purpose of this invention is to provide a refrigerated dryer with an anti-clogging filter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a refrigerated dryer with anti-clogging filter, comprising a refrigerated dryer body, a ventilation plate, and an air inlet pipe. The ventilation plate is connected to the middle of the outer wall of the refrigerated dryer body, and the air inlet pipe is connected to one side of the top of the refrigerated dryer body, while the air outlet pipe is connected to the other side of the top of the refrigerated dryer body. A base is connected to the bottom of the outer wall of the refrigerated dryer body. A cleaning mechanism is provided on the outer wall of the ventilation plate, and the cleaning mechanism includes a servo motor, a transmission column, a limit seat, a filter plate, a fixed seat, a rubber strip, a fixed rod, a spring, a guide plate, a drive motor, a limit plate, and a fixed box. A servo motor is installed on one side of the top of the base, and the output end of the servo motor is connected to the transmission column. The limit seat is sleeved on the outer wall of the transmission column. The filter plate is connected to the top of the outer wall of the limit seat, and the fixed seat is connected to the top of the outer wall of the filter plate.

[0021] 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.

[0022] Please see Figures 1-7This utility model provides a technical solution: a refrigerated dryer with anti-clogging filter, comprising a refrigerated dryer body 1, a ventilation plate 2, and an air inlet pipe 3. The ventilation plate 2 is connected to the middle of the outer wall of the refrigerated dryer body 1, and the air inlet pipe 3 is connected to one side of the top of the refrigerated dryer body 1, and the air outlet pipe 4 is connected to the other side of the top of the refrigerated dryer body 1. A base 5 is connected to the bottom of the outer wall of the refrigerated dryer body 1. A cleaning mechanism 6 is provided on the outer wall of the ventilation plate 2, and the cleaning mechanism 6 includes a servo motor 601, a transmission column 602, a limit seat 603, a filter plate 604, and a fixing seat. 605, rubber strip 606, fixing rod 607, spring 608, guide plate 609, drive motor 610, limiting plate 611, and fixing box 612. A servo motor 601 is installed on one side of the top of the base 5, and the output end of the servo motor 601 is connected to a transmission column 602. A limiting seat 603 is sleeved on the outer wall of the transmission column 602. A filter screen plate 604 is connected to the top of the outer wall of the limiting seat 603, and a fixing seat 605 is connected to the top of the outer wall of the filter screen plate 604. The side of the outer wall of the filter screen plate 604 near the fixing seat 605 is connected to... A rubber strip 606; a locking groove is provided inside the limiting seat 603, and the bottom end of the outer wall of the filter screen plate 604 extends into it; the limiting seat 603 has a "C" shaped structure; a fixing rod 607 is slidably connected inside the fixing seat 605, and a spring 608 is sleeved in the middle of the outer wall of the fixing rod 607; a guide plate 609 is welded to the top of the outer wall of the fixing rod 607; the upper and lower sides of the spring 608 are connected to the fixing seat 605 and the fixing rod 607, and the fixing seat 605, the fixing rod 607 and the spring 608 form an elastic telescopic mechanism. 05 has an "F" shaped structure; a drive motor 610 is installed on one side of the top of the main body 1 of the refrigerated dryer, and the output end of the drive motor 610 is connected to the limiting plate 611. The fixing rods 607 are evenly distributed, and the guide plate 609 and the fixing rods 607 have an "E" shaped structure; a fixing box 612 is welded to the middle of the top of the fixing seat 605. The fixing box 612 has a limiting groove inside, and the limiting groove is semi-circular, and the limiting plate 611 extends into it; the ventilation plate 2 has equally spaced ventilation holes inside, and the air inlet pipe 3 and the air outlet pipe 4 are parallel to each other.

[0023] In practice, during the use of the refrigerated dryer, because the ventilation plate 2 is equipped with a filter screen 604 on the outside, when the ventilation plate 2 is ventilating and dissipating heat, the incoming air is filtered by the filter screen 604 to prevent dust from entering the interior of the refrigerated dryer body 1 in large quantities through the ventilation plate 2, thereby preventing the internal components of the refrigerated dryer body 1 from malfunctioning due to the accumulation of a large amount of dust.

[0024] As the filter screen 604 becomes clogged with excessive dust over time, the following steps are taken: First, the drive motor 610 is started. Since the output of the drive motor 610 is connected to the limit plate 611, starting the drive motor 610 will cause the limit plate 611 to rotate until it moves out of the fixing box 612, thereby releasing the limit on the fixing seat 605. Next, the servo motor 601 is started. Since the output of the servo motor 601 is connected to the transmission column 602, starting the servo motor 601 will cause the transmission column 602 to rotate. The transmission column 602 rotates, which in turn drives the limit seat 603 to rotate. Then, the limit seat 603 rotates, which drives the filter screen 604 to rotate until the rubber strip 606 on the top of the filter screen 604 repeatedly collides with the ground, causing the filter screen 604 to vibrate. This causes the dust filtered by the filter screen 604 to be shaken off, thus preventing the filter screen 604 from being clogged by dust and affecting the dustproof effect, and preventing the shaken-off dust from entering the main body 1 of the refrigerated dryer through the ventilation plate 2.

[0025] When it is necessary to thoroughly clean the filter screen 604, since the guide plate 609 is connected to the fixed rod 607, first move the guide plate 609 upward to drive the fixed rod 607 upward together until the fixed rod 607 is disengaged from the filter screen 604, thereby removing the limit on the filter screen 604. Then, the filter screen 604 can be moved out of the limiting seat 603 for cleaning. This can facilitate dust prevention and prevent filter clogging when the refrigerated dryer is in use.

[0026] After the filter screen 604 is thoroughly cleaned, it is first inserted into the limiting seat 603. Then, the spring 608 resets the filter screen 604 so that the fixing rod 607 is inserted into the filter screen 604, thereby limiting the filter screen 604. Then, the servo motor 601 is started so that the filter screen 604 is rotated to a vertical position. Then, the drive motor 610 is started so that the limiting plate 611 is rotated into the fixing box 612, thereby limiting the top of the filter screen 604 and fixing the filter screen 604.

[0027] In summary, when using this type of filter-anti-clogging refrigerated air dryer, the main body 1 of the refrigerated air dryer is first installed in the designated position via the base 5. Then, air is introduced into the main body 1 through the inlet pipe 3. At this time, heat exchange occurs between the refrigerant inside the main body 1 and the compressed air, causing the compressed air temperature to drop before being discharged through the outlet pipe 4. Furthermore, a specific cooling method is used to further reduce the temperature of the compressed air, achieving the drying purpose. During this process, the heat generated by the main body 1 is dissipated by the fan through the ventilation plate 2, preventing damage to internal components due to overheating. The existing technology, which will not be elaborated in detail here, filters the air entering through the ventilation plate 2 by the cleaning mechanism 6 to prevent dust from entering the interior of the refrigerated dryer body 1 in large quantities through the ventilation plate 2, thereby preventing the internal components of the refrigerated dryer body 1 from malfunctioning due to the accumulation of dust; and causes the rubber strip 606 on the top of the filter screen 604 to repeatedly collide with the ground, thereby shaking off the dust filtered by the filter screen 604, preventing the filter screen 604 from being blocked by dust and affecting the dustproof effect. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
