Technical Field
[0001] This utility model relates to the field of refrigerated dryer technology, and in particular to a multi-pipe filtration structure for a refrigerated dryer. Background Technology
[0002] A cooling dryer is a device used to remove moisture or humidity from materials. It works by placing the material in a low-temperature environment, causing the moisture and humidity to evaporate from the material. Then, through cooling and condensation, the vapor is turned into water, ultimately achieving the desired degree of dryness for the material.
[0003] A search revealed Chinese patent CN221036670U, which discloses a multi-stage refrigerated dryer. The technical problem is that methods using activated carbon or filters to clean the air entering the dryer during drying are inefficient, requiring frequent replacements and incurring high costs. The solution is a multi-stage refrigerated dryer comprising a dust removal component and a cleaning component. Compared to existing methods using activated carbon or filters, this dryer addresses the issue of frequent replacements and high costs associated with cleaning the dust removal component. By incorporating a cleaning structure to clean the dust removal structure, the cleaning structure can be used for extended periods without replacement or manual cleaning, thus reducing operating costs.
[0004] In the aforementioned existing technical solutions, a rotating plate is used to seal the dust discharge port, and the dust collector bag is blown by the blower box. This blows the dust inside and on the dust collector bag and it falls into the dust collection box, thus cleaning the dust collector bag. However, in actual use, when the blower blows air onto the dust collector bag, because the dust collector bag is connected to the inside of the dust collection box, the dust inside the dust collection box is stirred up and spread around under the influence of the airflow. When the blower stops working, the dust may remain inside the dust collector bag, resulting in incomplete dust removal. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model proposes a multi-pipe filtration structure for a refrigerated dryer. By using a drive motor to rotate the drive shaft in the direction of the ventilation slot, two filter plates are longitudinally distributed, dividing the space inside the sealed box. The filter plate located at the top rotates to the side closer to the ventilation slot as the drive shaft rotates. By replacing the filter plate, dust is filtered, ensuring the filtration effect of dust.
[0006] The technical solution to achieve the purpose of this utility model is as follows: a multi-pipe filtration structure for a refrigerated dryer, including a sealed box, multiple support columns fixedly installed on the bottom wall of the sealed box, a dryer body fixedly installed inside the sealed box, a fan fixedly installed on the inner bottom wall of the sealed box, the fan corresponding to the air inlet of the dryer body, multiple equidistant ventilation slots opened on the rear side wall of the sealed box, and a filter assembly provided inside the sealed box, the filter assembly including:
[0007] A drive shaft is rotatably mounted on the inner side wall of the sealed box, and a drive motor is fixedly mounted on the outer side wall of the sealed box. The output end of the drive motor is fixedly connected to the drive shaft.
[0008] There are multiple filter plates, which are fixedly installed circumferentially on the side wall of the drive shaft. Multiple movable grooves are equally spaced on the side wall of the filter plates. Connecting rods are slidably installed inside the movable grooves. Sealing plates are fixedly installed on the side wall of the connecting rods. Limiting blocks are provided on the side wall of the connecting rods away from the sealing plates.
[0009] In some embodiments, a dust collection drawer is slidably mounted on the side wall of the sealed box, and the dust collection drawer is located inside the sealed box on the side near the ventilation slot.
[0010] In some embodiments, the bottom wall of the dust collection drawer is provided with guide grooves, which are distributed in an inclined manner.
[0011] In some embodiments, the inner wall of the movable groove is inclined.
[0012] In some embodiments, the filtering component further includes:
[0013] There are also multiple sealing strips, which are fixedly installed on the side wall of the filter plate away from the drive shaft.
[0014] Compared with the prior art, the significant advantages of this utility model are:
[0015] Firstly, this invention, by placing multiple filter plates inside a sealed box, draws external air into the sealed box through a ventilation slot, where it is then filtered by the filter plates. Because the inner wall of the movable slot is inclined, the connecting rods on the upper and lower sides are inclined along the inner wall of the movable slot. Under the influence of the gravity of the sealing plate, the connecting rods on the front and rear sides slide up and down inside the movable slot. The sealing plate near the ventilation slot covers the side wall of the filter plate as the movable slot moves, blocking the side wall of the filter plate. This allows air to flow from the top filter plate and the filter plate away from the ventilation slot, improving the air filtration efficiency. By using a drive motor to rotate the drive shaft 90 degrees towards the ventilation slot, the two filter plates are longitudinally distributed, dividing the space inside the sealed box. The top filter plate rotates to the side closer to the ventilation slot as the drive shaft rotates, thus covering the side wall of the filter plate with the sealing plate. Simultaneously, as the connecting rods slide inside the movable slot, they knock off the impurities adhering to the side wall of the filter plate. This solves the problem of insufficient dust removal by existing dust collector bags.
[0016] Secondly, this utility model collects impurities from the filter plate on the side near the ventilation slot through a dust collection drawer, and the guide groove facilitates the accumulation of impurities inside the dust collection drawer, making it convenient for centralized processing of impurities.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0024] This utility model provides an improved multi-pipe filtration structure for a refrigerated dryer. The technical solution of this utility model is as follows:
[0025] like Figures 1-3 As shown, a multi-pipe filtration structure for a refrigerated dryer includes a sealed box 1. Multiple support columns 2 are fixedly installed on the bottom wall of the sealed box 1. The dryer body 3 is fixedly installed inside the sealed box 1. A fan 13 is fixedly installed on the inner bottom wall of the sealed box 1. The fan 13 corresponds to the air inlet of the dryer body 3. The dryer body 3 and the fan 13 are both existing technologies and will not be described in detail here. Multiple equidistant ventilation slots 4 are opened on the rear side wall of the sealed box 1. A filter assembly is provided inside the sealed box 1. The filter assembly includes a drive shaft 5, a filter plate 6, and a sealing strip 12.
[0026] The drive shaft 5 is rotatably mounted on the inner side wall of the sealing box 1, and the drive motor 11 is fixedly mounted on the outer side wall of the sealing box 1. The output end of the drive motor 11 is fixedly connected to the drive shaft 5.
[0027] There are multiple filter plates 6, which are circumferentially and fixedly installed on the side wall of the drive shaft 5. Multiple movable grooves 7 are equidistantly opened on the side wall of each filter plate 6. The inner side wall of each movable groove 7 is inclined, and a connecting rod 8 is slidably installed inside the movable groove 7. A sealing plate 9 is fixedly installed on the side wall of the connecting rod 8. A limit block 10 is provided on the side wall of the connecting rod 8 away from the sealing plate 9. By placing multiple filter plates 6 inside the sealed box 1, the operation of the fan 13 draws outside air into the sealed box 1 through the ventilation groove 4, and then filters it. Plate 6 filters impurities in the air. Since the inner wall of the movable groove 7 is inclined, the connecting rods 8 on the upper and lower sides are inclinedly distributed along the inner wall of the movable groove 7. Under the influence of the gravity of the sealing plate 9, the connecting rods 8 on the front and rear sides slide up and down inside the movable groove 7. The sealing plate 9 near the ventilation groove 4 covers the side wall of the filter plate 6 as the movable groove 7 moves, blocking the side wall of the filter plate 6, so that the air flows from the filter plate 6 located at the top and the filter plate 6 far away from the ventilation groove 4. The air is filtered through the two filter plates 6, improving the air efficiency.
[0028] There are also multiple sealing strips 12, which are fixedly installed on the side wall of the filter plate 6 away from the drive shaft 5; the gap between the filter plate 6 and the inner wall of the sealing box 1 is filled by the sealing strips 12.
[0029] like Figures 1-2 As shown, in this embodiment, a dust collection drawer 14 is slidably installed on the side wall of the sealed box 1. The dust collection drawer 14 is located inside the sealed box 1 on the side near the ventilation slot 4. A guide groove 15 is provided on the bottom wall of the dust collection drawer 14, and the guide groove 15 is distributed in an inclined manner. By using the drive motor 11 to drive the drive shaft 5 to rotate 90 degrees in the direction of the ventilation slot 4, the two filter plates 6 are longitudinally distributed, dividing the space inside the sealed box 1. The filter plate 6 located at the top rotates to the side near the ventilation slot 4 as the drive shaft 5 rotates, so the sealing plate 9 covers the side wall of the filter plate 6. At the same time, as the connecting rod 8 slides inside the movable slot 7, it knocks off the impurities attached to the side wall of the filter plate 6. The dust collection drawer 14 collects the impurities on the side of the filter plate 6 near the ventilation slot 4. The guide groove 15 facilitates the accumulation of impurities inside the dust collection drawer 14, which is convenient for centralized processing of impurities.
[0030] The specific working method is as follows: Multiple filter plates 6 are installed inside the sealed box 1. At this time, the fan 13 draws outside air into the sealed box 1 through the ventilation slot 4, and then filters impurities in the air through the filter plates 6. Because the inner wall of the movable slot 7 is inclined, the connecting rods 8 on the upper and lower sides are inclined along the inner wall of the movable slot 7. Under the influence of the gravity of the sealing plate 9, the connecting rods 8 on the front and rear sides slide up and down inside the movable slot 7. The sealing plate 9 near the ventilation slot 4 covers the side wall of the filter plate 6 as the movable slot 7 moves, blocking the side wall of the filter plate 6, allowing air to flow from the filter plate 6 located at the top and the filter plate 6 away from the ventilation slot 4, passing through two... The filter plate 6 filters the air and improves the air efficiency. By using the drive motor 11 to drive the drive shaft 5 to rotate 90 degrees towards the ventilation slot 4, the two filter plates 6 are longitudinally distributed, dividing the space inside the sealed box 1. The filter plate 6 located at the top rotates to the side closer to the ventilation slot 4 as the drive shaft 5 rotates, so the sealing plate 9 covers the side wall of the filter plate 6. At the same time, as the connecting rod 8 slides inside the movable slot 7, it knocks off the impurities attached to the side wall of the filter plate 6. The impurities on the filter plate 6 on the side closer to the ventilation slot 4 are collected by the dust collection drawer 14. The guide slot 15 facilitates the accumulation of impurities inside the dust collection drawer 14, making it easy to centrally process the impurities.
