Description

Technical Field

[0001] This utility model belongs to the field of drying technology, and more specifically, it relates to a refrigerated dryer. Background Art

[0002] After steel pipes are rolled by a cold rolling mill, their surface and inner wall become covered with rolling lubricating oil from the mill. During the subsequent drying process, the residual grease will cause carbonization of the pipe wall under high temperature conditions, resulting in carburization on the pipe surface, which affects the quality of the steel pipe and shortens its service life.

[0003] The existing publication number CN221649108U discloses a refrigerated dryer, which has the function of controlling the hydraulic push rod to push the fixed seat through the controller, and at the same time the telescopic rod extends and retracts, causing the fixed seat to move up and down, thereby causing the rubber degreasing pad to contact the steel pipe for degreasing.

[0004] Based on the above, the inventors have discovered the following problems: However, the device removes oil solely through the oil removal pad. After prolonged use, a large amount of oil stains will adhere to the surface of the oil removal pad. When wiping the steel pipe again, a large amount of oil stains will still remain on the surface of the steel pipe. Furthermore, frequently replacing the oil removal pad is quite inconvenient.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a freeze dryer in order to achieve a more practical purpose. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a freeze dryer, which solves the problem that after long-term use, a large amount of oil stains will adhere to the surface of the degreasing pad, and a large amount of oil stains will still remain on the surface of the steel pipe when it is wiped later. The frequent replacement of the degreasing pad is also inconvenient.

[0007] This utility model provides a freeze dryer, which is achieved by the following specific technical means:

[0008] A freeze dryer includes a dryer body, a second chamber fixed to one side of the dryer body, and a first chamber fixed to one side of the second chamber. A steel pipe hole is drilled through the top center of the first chamber, the second chamber, and one side of the dryer body. Rotating rods are rotatably connected to the four corners of the inner wall of the first chamber. A cleaning cloth is wrapped around the outer wall of the middle of the four rotating rods. A pressing rod is fixed to the bottom of the inner wall of the first chamber. A first servo motor is fixed to the top of the outer wall of the first chamber away from the second chamber via a first support rod. A drive roller is fixed to the power output end of the first servo motor. A second servo motor is fixed to the top of the first chamber near the first servo motor via a second support rod. A first pulley is fixed to the power output end of the second servo motor. The first pulley is fixed to one of the rotating rods. A second pulley is rotatably connected to the middle of the outer wall of the first chamber near the first servo motor. A rotating wheel is fixed to one end of the second pulley. A transmission belt is provided on the outer wall of both the first and second pulleys.

[0009] Furthermore, limit rings are fixed on both sides of the middle of the four rotating rods, the cleaning cloth is located in the middle of the limit rings, and the top of the cleaning cloth is on the same horizontal plane as the middle of the steel pipe hole.

[0010] Furthermore, there are two squeezing rods, the distance between the two squeezing rods is less than the thickness of the cleaning cloth, and the two squeezing rods are located above and below the bottom of the cleaning cloth, respectively.

[0011] Furthermore, the middle part of the drive roller and the middle part of the steel pipe hole are located in the same vertical plane, and the vertical cross-section of the drive roller is H-shaped.

[0012] Furthermore, the rotating wheel is made of pneumatic rubber, and the rotating wheel and the steel pipe hole are located on the same horizontal plane.

[0013] Furthermore, water spray pipes are fixed on both sides of the middle part of the top of the second box, the water spray pipes are connected to external water pipes, and a water spray hole is opened through one side of the water spray pipe.

[0014] Furthermore, both the first and second boxes have drainage holes on one side of the bottom, and drainage valves are installed at the drainage holes.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, the steel pipe to be dried is inserted into the steel pipe hole of the first chamber. At this time, the first servo motor is started to drive the drive roller to rotate, guiding the steel pipe into the first chamber. Simultaneously, the second servo motor is started to drive the cleaning cloth to rotate. The cleaning cloth cleans the outer wall of the steel pipe inside the first chamber. After cleaning, the cleaning cloth rotates to the bottom of the first chamber and is squeezed and cleaned by the extrusion rod. The cleaned steel pipe enters the second chamber through the steel pipe hole. At this time, the water spray pipe sprays water to remove the cleaning agent on the surface of the steel pipe. Finally, it enters the drying machine for freeze drying, thereby achieving a more thorough degreasing effect without the need to replace the degreasing pad. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To the attached Figure 4 As shown:

[0027] This utility model provides a freeze dryer, including a dryer body 3. A second chamber 2 is fixed to one side of the dryer body 3, and a first chamber 1 is fixed to one side of the second chamber 2. Steel pipe holes 4 are drilled through the top center of the first chamber 1, the second chamber 2, and one side of the dryer body 3. Rotating rods 14 are rotatably connected to the four corners of the inner wall of the first chamber 1. Cleaning cloths 16 are wrapped around the outer walls of the four rotating rods 14. A pressing rod 17 is fixed to the bottom of the inner wall of the first chamber 1. A first servo motor 5 is fixed to the top of the outer wall of the first chamber 1 at the end away from the second chamber 2 via a first support rod 6. The power source of the first servo motor 5 is... A drive roller 7 is fixed at the output end. A second servo motor 9 is fixed at the top of the first housing 1 near the first servo motor 5 via a second support rod 8. A first pulley 10 is fixed at the power output end of the second servo motor 9. The first pulley 10 is fixed to one of the rotating rods 14. A second pulley 12 is rotatably connected to the middle of the outer wall of the first housing 1 near the first servo motor 5. A rotating wheel 13 is fixed at one end of the second pulley 12. A transmission belt 11 is provided on the outer wall of the first pulley 10 and the second pulley 12. A large amount of liquid containing cleaning agent is poured into the first housing 1 and submerges the squeezing rod 17.

[0028] Among them, limit rings 15 are fixed on both sides of the middle of the four rotating rods 14. The cleaning cloth 16 is located in the middle of the limit rings 15, and the top of the cleaning cloth 16 is on the same horizontal plane as the middle of the steel pipe hole 4. The limit rings 15 limit the cleaning cloth 16 to prevent the cleaning cloth 16 from shifting its position when rotating on the rotating rods 14. When the steel pipe is passed through the steel pipe hole 4, the cleaning cloth 16 can touch the steel pipe.

[0029] There are two squeezing rods 17. The distance between the two squeezing rods 17 is less than the thickness of the cleaning cloth 16. The two squeezing rods 17 are located above and below the bottom of the cleaning cloth 16, respectively. The squeezing rods 17 squeeze the cleaning cloth 16 so that the cleaning cloth 16 can be squeezed and cleaned in the cleaning liquid inside the first box 1.

[0030] The middle part of the drive roller 7 and the middle part of the steel pipe hole 4 are located on the same vertical plane. The vertical cross section of the drive roller 7 is H-shaped. By inserting the steel pipe into the steel pipe hole 4, the first servo motor 5 is started to drive the drive roller 7 to rotate, and the steel pipe is introduced into the first box 1.

[0031] The rotating wheel 13 is made of inflatable rubber. The rotating wheel 13 and the steel pipe hole 4 are located on the same horizontal plane. The rotating wheel 13 is driven to rotate by the second servo motor 9. The rotating wheel 13 made of inflatable rubber can fully compress the steel pipe, thereby causing the moving side in the first box 1 of the steel pipe side box to rotate. At the same time, the second servo motor 9 drives the rotating rod 14 to rotate, which drives the cleaning cloth 16 to rotate, cleaning the outer wall of the steel pipe inside the first box 1.

[0032] The second chamber 2 has water spray pipes 21 fixed on both sides of the middle part of the top. The water spray pipes 21 are connected to the external water pipes. A water spray hole 22 is opened through one side of the water spray pipe 21. The cleaned steel pipe enters the second chamber 2 through the steel pipe hole 4. At this time, the water spray pipe 21 sprays water to remove the cleaning agent on the surface of the steel pipe. Finally, it enters the dryer body 3 for freeze drying.

[0033] Both the first chamber 1 and the second chamber 2 have drainage holes on one side of the bottom, and drainage valves are installed at the drainage holes. When it is necessary to replace the cleaning fluid inside the first chamber 1 after long-term use, the drainage valve can be opened.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, a large amount of liquid containing detergent is first poured into the first housing 1, covering the squeezing rod 17. Then, the steel pipe to be dried is inserted into the steel pipe hole 4 of the first housing. At this time, the first servo motor 5 is started to drive the drive roller 7 to rotate, guiding the steel pipe into the first housing 1. Simultaneously, the second servo motor 9 is started to drive the rotating wheel 13 to rotate. The rotating wheel 13, made of inflatable rubber, can fully squeeze the steel pipe, thereby causing the steel pipe to move and rotate within the first housing 1. At the same time, the second servo motor 9 drives the rotating rod 14 to rotate, which in turn drives the cleaning cloth 16 to rotate. The cleaning cloth 16 is limited by the limiting ring 15. To prevent the cleaning cloth 16 from shifting position when rotating on the rotating rod 14, the cleaning cloth 16 cleans the outer wall of the steel pipe inside the first chamber 1. After cleaning, the cleaning cloth 16 rotates to the bottom of the first chamber 1, and the squeezing rod 17 squeezes the cleaning cloth 16 so that it can be squeezed and cleaned in the cleaning liquid inside the first chamber 1. The cleaned steel pipe enters the second chamber 2 through the steel pipe hole 4. At this time, the water spray pipe 21 sprays water to remove the cleaning agent on the surface of the steel pipe. Finally, it enters the dryer body 3 for freeze drying. When it is necessary to replace the cleaning liquid inside the first chamber 1 after long-term use, simply open the drain valve.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
