Description

Technical Field

[0001] This utility model belongs to the field of refrigerated dryer drainage technology, specifically relating to a refrigerated dryer with an integrated automatic drainage and anti-clogging structure. Background Technology

[0002] A refrigerated air dryer is short for a refrigerant dryer. Refrigerated air dryers use refrigerant to exchange heat with compressed air, lowering the temperature of the compressed air to the dew point. The hot, humid compressed air from the air compressor is first pre-cooled by an air-to-air heat exchanger. Then, the pre-cooled air is further cooled by the refrigerant circulation loop of the refrigerated air dryer in an air-to-refrigerant heat exchanger, exchanging heat with the cold air that has already been cooled to the pressure dew point from the evaporator, further reducing the temperature of the compressed air.

[0003] Refrigerated dryers produce a lot of condensate when they are working, and a drainer needs to be installed to drain the condensate. However, solid impurities in the water can easily clog the drainer, affecting the drainage effect and resulting in a high failure rate. Utility Model Content

[0004] The purpose of this invention is to provide a refrigerated dryer with an integrated automatic drainage and anti-clogging structure, which solves the problems of existing technologies where solid impurities in the water easily clog the drain, affecting drainage performance and resulting in a high failure rate.

[0005] The specific technical solution adopted in this utility model is as follows: A refrigerated dryer with an integrated automatic drainage and anti-clogging structure includes: The refrigerated dryer body has a drainage tank on its bottom surface. A dredging mechanism is provided inside the drain tank and is used to dredge the bottom of the drain tank. A material pushing mechanism is installed inside the drainage tank and is used to clean the inner wall of the drainage tank.

[0006] In a preferred embodiment, the bottom surface of the refrigerated dryer body is connected to a water outlet pipe, the top surface of the drain tank is fixedly connected to the refrigerated dryer body, and a drain outlet is provided at the bottom of the drain tank.

[0007] In a preferred embodiment, the unblocking mechanism includes a fixed box, a servo motor, a drive gear, a driven gear, a turntable, a rotating rod, a lifting plate, a first connecting rod, a pressure plate, a fixed plate, and insert rods. The fixed box is fixedly mounted on the bottom surface of the refrigerated dryer body. The servo motor is fixedly mounted on the back of the fixed box. The drive gear is fixedly mounted at the output end of the servo motor. The driven gear meshes with the driven gear on its outer side. The turntable is fixedly mounted on the front side of the driven gear. The rotating rod is fixedly mounted on the front side of the turntable. The lifting plate passes through the outer side of the rotating rod. The first connecting rod is fixedly mounted on the bottom surface of the lifting plate. The pressure plate is fixedly mounted on the bottom surface of the first connecting rod. The fixed plate is fixedly mounted on the bottom surface of the pressure plate. Multiple insert rods are fixedly mounted on the bottom surface of the fixed plate.

[0008] In a preferred embodiment, the output end of the servo motor passes through the fixed box to the inside of the fixed box and is rotatably connected to the fixed box. The back of the driven gear is rotatably connected to the fixed box through a bearing. The front of the lifting plate is provided with a transverse groove adapted to the rotating rod. The rotating rod is movably connected to the lifting plate through the transverse groove. The first connecting rod passes through the fixed box to the outside of the fixed box and is slidably connected to the fixed box.

[0009] In a preferred embodiment, symmetrical guide rods are fixedly installed between the upper and lower sides inside the fixed box, and the guide rods pass through the lifting plate and are slidably connected to the lifting plate.

[0010] In a preferred embodiment, the pushing mechanism includes an inclined plate, a second connecting rod, a limiting plate, and a return spring. The drainage tank is provided with symmetrical inclined plates. Symmetrical second connecting rods are fixedly provided on the sides of the inclined plates that are close to each other. A limiting plate is fixedly provided on the other side of the second connecting rod. A return spring is fixedly provided on the other side of the limiting plate. The pressure plate is provided with a groove adapted to the limiting plate. The limiting plate is slidably connected to the pressure plate through the groove. The second connecting rod extends into the groove of the pressure plate and is slidably connected to the pressure plate. The end of the return spring away from the limiting plate is fixedly connected to the inner wall of the groove.

[0011] The technical effects achieved by this utility model are as follows: This utility model incorporates a dredging mechanism. When water from the refrigerated dryer enters the drain tank through the outlet pipe, the servo motor drives the drive gear to rotate, which in turn drives the rotating rod to rotate continuously. The rotation of the rotating rod causes the lifting plate to move up and down periodically. The movement of the lifting plate causes the insertion rod to move up and down periodically. When there is a lot of solid impurities accumulated at the drain outlet, the up and down movement of the insertion rod can dredge the drain outlet and accelerate the movement of solid impurities downward to the outside of the drain outlet. The periodic up and down movement of the insertion rod can prevent blockage at the drain outlet and reduce the failure rate. This utility model incorporates a pushing mechanism. When the lifting plate of the unblocking mechanism moves up and down, it drives the pressure plate to move up and down. Simultaneously, the pressure plate moves up and down, which in turn drives the pushing mechanism to move up and down. When the pushing mechanism moves downward, the inclined plate contacts the inclined surface inside the drainage tank, allowing the inclined plate to slide downward along the inclined surface inside the drainage tank. This pushes the solid impurities attached to the inclined surface away from the drain outlet, preventing solid impurities from accumulating on the inclined surface and causing blockage.

[0018] Please see the appendix Figures 1 to 2 As shown, this utility model provides a refrigerated dryer with an integrated automatic drainage and anti-clogging structure, including: a refrigerated dryer body 100, a dredging mechanism 300 and a material pushing mechanism 400. The bottom of the refrigerated dryer body 100 is connected to a water outlet pipe 101. Support columns are fixedly installed on the left and right sides of the refrigerated dryer body 100. A drain box 200 is fixedly installed on the bottom surface of the refrigerated dryer body 100, and a drain outlet 201 is provided at the bottom of the drain box 200.

[0019] In a preferred embodiment, please refer to Figures 1 to 3 The drain tank 200 is equipped with a dredging mechanism 300, which consists of a fixed box 301, a servo motor 302, a drive gear 303, a driven gear 304, a turntable 305, a rotating rod 306, a lifting plate 307, a first connecting rod 308, a pressure plate 309, a fixed plate 310, and an insert rod 311. The fixed box 301 is fixedly mounted on the bottom surface of the refrigerated dryer body 100, and the servo motor 302 is fixedly installed on the back of the fixed box 301. The outer shell of the servo motor 302 is made of a material with good rust and moisture resistance. A drive gear 303 is fixedly installed at the output end of 302. A driven gear 304 meshes with the outside of the drive gear 303. A turntable 305 is fixedly installed on the front of the driven gear 304. A rotating rod 306 is fixedly installed on the front of the turntable 305. A lifting plate 307 is installed through the outside of the rotating rod 306. A first connecting rod 308 is fixedly installed on the bottom surface of the lifting plate 307. A pressure plate 309 is fixedly installed on the bottom surface of the first connecting rod 308. A fixing plate 310 is fixedly installed on the bottom surface of the pressure plate 309. Multiple insert rods 311 are fixedly installed on the bottom surface of the fixing plate 310.

[0020] In this embodiment, the output end of the servo motor 302 passes through the fixed box 301 to the inside of the fixed box 301 and is rotatably connected to the fixed box 301. The back of the driven gear 304 is rotatably connected to the fixed box 301 through a bearing. The front of the lifting plate 307 is provided with a transverse groove adapted to the rotating rod 306. The rotating rod 306 is movably connected to the lifting plate 307 through the transverse groove. Symmetrical guide rods are fixedly provided between the upper and lower sides inside the fixed box 301. The guide rods pass through the lifting plate 307 and are slidably connected to the lifting plate 307. The guide rods are used to guide the movement of the lifting plate 307. The first connecting rod 308 passes through the fixed box 301 to the outside of the fixed box 301 and is slidably connected to the fixed box 301.

[0021] In this embodiment, when water from the refrigerated dryer body 100 enters the drain tank 200 through the outlet pipe 101, the servo motor 302 drives the drive gear 303 to rotate, which in turn drives the driven gear 304 to rotate. The driven gear 304 rotates, causing the turntable 305 and the rotating rod 306 to rotate continuously. The rotating rod 306 rotates, causing the lifting plate 307 to move up and down periodically. The movement of the lifting plate 307 causes the first connecting rod 308, the pressure plate 309, the fixing plate 310, and the insert rod 311 to move up and down periodically. When the insert rod 311 moves to the lowest position, the bottom surface of the insert rod 311 is lower than the bottom surface of the drain outlet 201. When there is a lot of solid impurities accumulated at the drain outlet 201, the up and down movement of the insert rod 311 can clear the drain outlet 201 and accelerate the movement of solid impurities downward to the outside of the drain outlet 201. The periodic up and down movement of the insert rod 311 can prevent blockage at the drain outlet 201 and reduce the failure rate.

[0022] In a preferred embodiment, please refer to Figures 1 to 4 The refrigerated dryer body 100 is equipped with a pushing mechanism 400, which consists of an inclined plate 401, a second connecting rod 402, a limiting plate 403 and a return spring 404. The drain tank 200 is equipped with symmetrical inclined plates 401. The top and bottom surfaces of the inclined plates 401 are inclined surfaces. Symmetrical second connecting rods 402 are fixedly installed on the sides of the inclined plates 401 that are close to each other. A limiting plate 403 is fixedly installed on the other side of the second connecting rod 402. A return spring 404 is fixedly installed on the other side of the limiting plate 403.

[0023] In this embodiment, the pressure plate 309 is provided with a sliding groove that is adapted to the limiting plate 403. The limiting plate 403 is slidably connected to the pressure plate 309 through the sliding groove. The second connecting rod 402 extends into the sliding groove of the pressure plate 309 and is slidably connected to the pressure plate 309. The end of the return spring 404 away from the limiting plate 403 is fixedly connected to the inner wall of the sliding groove.

[0024] In this embodiment, when the lifting plate 307 of the unblocking mechanism 300 moves up and down, it drives the pressure plate 309 to move up and down. Simultaneously, the pressure plate 309 moves up and down, which in turn drives the pushing mechanism 400 to move up and down. When the pushing mechanism 400 moves downward, the inclined plate 401 contacts the inclined surface inside the drainage tank 200, causing the inclined plate 401 to slide downward along the inclined surface inside the drainage tank 200. At the same time, the inclined plate 401 moves relative to the pressure plate 309 towards the pressure plate 309, compressing the return spring 404. When the pushing mechanism 400 moves upward... When activated, the return spring 404 pushes the limit plate 403 to drive the inclined plate 401 to slide upward along the inclined surface inside the drain tank 200. At the same time, the inclined plate 401 moves away from the pressure plate 309 relative to the pressure plate 309. The downward sliding of the inclined plate 401 on the inclined surface inside the drain tank 200 can push the solid impurities attached to the inclined surface away to the drain outlet 201. The up and down movement of the pressure plate 309 can drive the inclined plate 401 to slide up and down on the inclined surface inside the drain tank 200, avoiding the accumulation of solid impurities on the inclined surface and causing blockage.

[0025] The working principle of this utility is as follows: When the device is in use, the condensate generated by the refrigerated dryer body 100 enters the drain tank 200 through the outlet pipe 101. The servo motor 302 drives the drive gear 303 to rotate, which in turn drives the driven gear 304 to rotate. The driven gear 304 drives the turntable 305 and the rotating rod 306 to rotate continuously. The rotating rod 306 drives the lifting plate 307 to move up and down periodically. The movement of the lifting plate 307 drives the first connecting rod 308, the pressure plate 309, the fixing plate 310, and the insert rod 311 to move up and down periodically. When there is a lot of solid impurities accumulated at the drain outlet 201, the up and down movement of the insert rod 311 can clear the drain outlet 201 and accelerate the movement of solid impurities downward to the outside of the drain outlet 201. The periodic up and down movement of the insert rod 311 can prevent blockage at the drain outlet 201 and reduce the failure rate. At the same time, the up and down movement of the pressure plate 309 can drive the pushing mechanism 400. When the pushing mechanism 400 moves downward, the inclined plate 401 contacts the inclined surface inside the drainage tank 200, causing the inclined plate 401 to slide downward along the inclined surface inside the drainage tank 200. At the same time, the inclined plate 401 moves towards the pressure plate 309 relative to the pressure plate 309, and the return spring 404 is compressed. When the pushing mechanism 400 moves upward, the return spring 404 pushes the limiting plate 403, causing the inclined plate 401 to slide upward along the inclined surface inside the drainage tank 200. At the same time, the inclined plate 401 moves away from the pressure plate 309 relative to the pressure plate 309. The downward sliding of the inclined plate 401 on the inclined surface inside the drainage tank 200 can push the solid impurities attached to the inclined surface away to the drain outlet 201. The up-and-down movement of the pressure plate 309 can cause the inclined plate 401 to slide up and down on the inclined surface inside the drainage tank 200, preventing solid impurities from accumulating on the inclined surface and causing blockage.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
