Description

Technical Field

[0001] This utility model relates to the field of drying technology for ship refrigeration equipment, specifically a drying structure for ship refrigeration equipment. Background Technology

[0002] As is well known, maintaining internal dryness is crucial in marine refrigeration systems. Excessive humidity can cause rust and corrosion of internal metal components, affecting equipment performance and lifespan. Drying systems typically use simple filters or desiccants to remove moisture from the air, requiring frequent replacement of the desiccant. Furthermore, because they are directly installed inside the refrigeration unit, installation and disassembly are complex, leading to high maintenance costs and significant time consumption. In early designs, the drying box was fixed in a designated location using screws. However, due to the frequent voyages and humid surroundings of ships, even with anti-corrosion coatings, the screws would rust, making it difficult to disassemble the drying box and replace the internal desiccant. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a drying structure for a ship refrigeration device, which has the following beneficial effects:

[0016] The drying structure of this ship's refrigeration unit allows for the fixing or loosening of filter boxes on two drying tanks simply by rotating a single adjusting shaft. This simplifies maintenance and makes installation, disassembly, and replacement of the moisture-absorbing layer quick and easy, which is especially important for marine environments requiring frequent maintenance. It reduces downtime and improves efficiency. The design of the inclined trough and fastening plate, combined with a two-way screw driving the sliding block, generates downward pressure, ensuring the filter boxes are firmly fixed to the drying tanks under any circumstances. Even in severe sea conditions with violent rolling, the drying system remains operational, guaranteeing stable dehumidification. Air enters the filter box through the perforations, effectively absorbs moisture through the moisture-absorbing layer, and is then discharged through the exhaust duct, forming a closed and efficient airflow circulation system. This ensures that the dried air is reintroduced into the refrigeration unit, maintaining a dry internal environment and significantly improving dehumidification efficiency. The two fans can be operated individually or alternately as needed, not only delaying the need for personnel to replace the moisture-absorbing layer but also reducing the workload of individual fans without affecting the overall dehumidification effect, thus achieving long-term stable dehumidification operation.

[0022] 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.

[0023] Please see Figure 1-4This utility model relates to a drying structure for a ship refrigeration device, comprising a drying box 1, an installation mechanism on the drying box 1, a drying trough and a fastening box 2 at the top of the drying box 1, two drying troughs, and the fastening box 2 located between the two drying troughs. An air inlet pipe 3 is provided between the drying trough and one side of the drying box 1, and an air outlet pipe 4 is provided between the drying trough and the other side of the drying box 1. A filter box 5 is provided on the drying trough, with through holes on both sides. A moisture-absorbing layer 6 is provided inside the filter box 5. A fastening trough is provided inside the fastening box 2, with bearing seats on both sides of the fastening trough. A bidirectional lead screw 7 is provided between the two bearing seats, and sliding joints are provided at both ends of the bidirectional lead screw 7. The sliding block 8 has a threaded hole, through which the bidirectional lead screw 7 passes. A fastening mechanism is provided between the sliding block 8 and the filter box 5. The fastening mechanism includes an inclined groove 9 and a through groove. The inclined groove 9 is located on one side of the filter box 5, and the through groove is located between the drying tank and the fastening groove. A fastening inclined plate 10 is provided on the through groove, and the fastening inclined plate 10 is connected to the sliding block 8. An adjusting bevel tooth 11 is provided on the bidirectional lead screw 7. An adjusting hole is located at the top of the fastening box 2, and an adjusting shaft 12 is provided on the adjusting hole. An output bevel tooth 13 is provided at the bottom end of the adjusting shaft 12 and engages with the adjusting bevel tooth 11. A guide mechanism is provided between the fastening groove and the two fastening inclined plates 10. The air inlet pipe 3 is equipped with a fan 20. In this embodiment, the personnel place the filter boxes 5 on the two drying tanks against the drying tanks. At this time, the through holes on both sides of the filter box 5 are aligned with the air inlet pipe 3 and the air outlet pipe 4. The inclined groove 9 on one side of the filter box 5 in the fastening mechanism is aligned with the fastening inclined plate 10. The personnel rotate the adjusting shaft 12 on the fastening box 2. The adjusting shaft 12 rotates in the adjusting hole. The adjusting shaft 12 drives the output bevel gear 13 to rotate by an angle. The adjusting bevel gear 11 can drive the bidirectional screw 7 to rotate by an angle. The two bearing seats can improve the rotational stability of the bidirectional screw 7. By passing the threaded holes of the sliding blocks 8 at both ends through the bidirectional screw 7, the sliding blocks 8 can slide linearly in the fastening groove. The sliding blocks 8 drive the fastening inclined plate 10 to move, thereby making the two fastening inclined plates move. The filter box 5 is firmly fixed in the drying tank by the inclined groove 9 at the corresponding position. The inclined angle of the inclined groove 9 and the fastening inclined plate 10 can generate downward pressure to ensure that the filter box 5 is firmly and reliably pressed against the drying tank. The filter boxes 5 on the two drying tanks can be locked by simply rotating one adjusting shaft 12. The two air inlet pipes 3 and the air outlet pipe 4 are connected to the inside of the ship's refrigeration unit. Air can be drawn into the ship's refrigeration unit by using the fan 20. The air passes through the through hole to secure the inside of the filter box 5, and then passes through the moisture absorption layer 6 to absorb moisture, thereby making the air dry. Then it is discharged back into the ship's refrigeration unit through the air outlet pipe 4, thereby realizing the drying operation inside the ship's refrigeration unit.Personnel can set the two fans 20 to operate alternately and independently as needed, which can delay the time for personnel to replace the moisture-absorbing layer 6 and achieve long-term dehumidification operation. During replacement, personnel can reverse the rotation of the adjusting shaft 12 to reverse the rotation of the bidirectional lead screw 7, causing the two fastening inclined plates 10 to disengage from the corresponding inclined grooves 9, thereby directly removing the filter box 5 for replacement of the moisture-absorbing layer 6.

[0024] In this solution, the guiding mechanism includes a slide groove 14 and a slider 15. The slide groove 14 is formed at the bottom end of the fastening groove. The slider 15 is located in the slide groove 14 and connected to the fastening inclined plate 10. The slider 15 moves with the fastening inclined plate 10 and moves linearly in the slide groove 14, which can improve the stability of the movement of the fastening inclined plate 10.

[0025] In this solution, the installation mechanism includes a mounting base 16, which is installed on both ends of the drying chamber 1. The mounting base 16 has mounting holes 17. Through the mounting holes 17 on the mounting base 16, it is convenient for personnel to use bolts or other parts to fix the drying chamber 1 to one side or other positions of the refrigeration device. The mounting base 16 being located on both ends of the drying chamber 1 can further improve the stability and reliability of the installation.

[0026] In this solution, a three-way valve 18 is provided between the two air inlet pipes 3, and an air duct 19 is provided on the three-way valve 18. By using the air duct 19, dehumidification and drying operations can be carried out by connecting only one pipe to the refrigeration unit. By making the three-way valve 18 easy to connect the air duct 19 to any one of the two filter boxes 5, it is convenient to carry out dehumidification and drying operations through the other filter box 5 when replacing one filter box 5, so as to achieve non-stop operation.

[0027] In this design, a bearing is provided between the adjusting shaft 12 and the adjusting hole, which can improve the rotational stability of the adjusting shaft 12.

[0028] In this design, sealing rings are provided on both sides of the through hole, which can improve the sealing performance between the through hole and the drying tank.

[0029] In this solution, the sealing ring is made of a high and low temperature resistant material, which improves the sealing ring's adaptability to high and low temperatures.

[0030] In this design, a flange 21 is provided between the air intake pipe 19 and the air outlet pipe 4, which facilitates the connection of external pipes to the air intake pipe 19 and the air outlet pipe 4.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
