Description

Technical Field

[0001] This utility model relates to a dehumidification device, specifically a dehumidification device for spraying paint in the hull of a ship. Background Technology

[0002] During the fabrication of the ship's hull, painting is necessary to achieve corrosion and rust prevention, protect structural safety, and maintain aesthetics and the integrity of the hull. Before painting, the hull must be dehumidified to ensure better adhesion of the paint.

[0003] Existing dehumidification devices used for painting ship hulls are complex in structure and poorly designed. They typically employ drying equipment to heat the hull environment for dehumidification. However, due to the vast space inside the ship's hull, drying methods are extremely inefficient and time-consuming to complete dehumidification. Furthermore, the capillary tubes in dehumidification devices usually have a simple structure, extending the refrigerant flow path through a slender loop to achieve a pressure reduction effect. However, this pressure reduction is ineffective at high refrigerant flow rates, significantly impacting dehumidification. Therefore, the inventors have improved the structure of the dehumidification device. Utility Model Content

[0004] The purpose of this invention is to provide a dehumidification device for spraying paint in the hull of a ship. This dehumidification device has a simple structure and reasonable design. It uses a compressor to compress the refrigerant, causing the high-temperature, high-pressure gas to condense into a low-temperature, high-pressure gas, which can effectively raise the temperature of the hull. In conjunction with an evaporator, the low-temperature, low-pressure refrigerant liquid absorbs a large amount of external heat and vaporizes into dry saturated vapor, achieving the purpose of absorbing heat from the outside and cooling. It also causes water to condense into water droplets and be discharged, thus quickly dehumidifying the hull. It is suitable for most ship cabin environments, making the dehumidification more efficient, saving time, and also helps to obstruct the flow of refrigerant, slowing down its flow rate, greatly improving its pressure reduction efficiency, and achieving better vaporization effect in the subsequent process, thus solving the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dehumidification device for spraying paint in the hull of a ship. The dehumidification device includes a base and a support frame fixed to the upper surface of the base. A condensing mechanism and an evaporating mechanism connected to the condensing mechanism are arranged on the support frame. The condensing mechanism includes a compressor and an exhaust pipe connected to the output end of the compressor. The exhaust pipe extends upward and is connected to an outlet pipe. The end of the outlet pipe away from the exhaust pipe is connected to a condenser. The condenser is fixed to the support frame. A solenoid valve is arranged between the exhaust pipe and the outlet pipe. The evaporating mechanism includes a drying filter and a capillary tube arranged on one side of the drying filter. The end of the condenser away from the outlet pipe is connected to the drying filter. The two ends of the capillary tube are respectively connected to a refrigerant input pipe and a refrigerant output pipe. The end of the refrigerant input pipe away from the capillary tube is connected to the drying filter, and the end of the refrigerant output pipe away from the capillary tube is connected to the evaporator.

[0006] Preferably, it also includes an electrical control cabinet fixed on the support frame, which is electrically connected to the condensing mechanism and the evaporating mechanism respectively, and provides electrical energy to the condensing mechanism and the evaporating mechanism respectively.

[0007] Preferably, both the compressor and the evaporator are fixed to the upper surface of the base, and the compressor is set horizontally.

[0008] Preferably, both the dryer filter and the capillary tubes are fixed on the support frame. A total of several capillary tubes are provided, and the capillary tubes are evenly distributed on the support frame. The capillary tubes are connected as one unit, and the capillary tubes undergo multiple bends to minimize their footprint.

[0009] Preferably, the capillary includes a main body, which is a hollow cavity structure with openings at both ends. Multiple flow-blocking baffles are fixed inside the cavity, and the multiple flow-blocking baffles are distributed on both sides of the cavity and are arranged in a cross pattern.

[0010] Preferably, the flow-blocking baffle includes a first inclined plate and a second inclined plate fixed to the first inclined plate, with the end of the first inclined plate away from the second inclined plate fixed to the inner wall of the cavity of the main pipe.

[0011] Preferably, a gap is provided between the second inclined plate and the inner wall of the cavity of the main tube, and the value of the gap is between 1.5cm and 2.5cm.

[0012] Preferably, a suction pipe is connected to the end of the evaporator away from the capillary tube. The suction pipe is fixed to the support frame and is connected to the output end of the compressor. The compressor can draw back the vapor that has been converted into low-pressure superheated vapor in the suction pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides a dehumidification device for spraying paint in the hull of a ship. The dehumidification device includes a base and a support frame fixed to the upper surface of the base. A condensing mechanism and an evaporating mechanism connected to the condensing mechanism are arranged on the support frame. The overall structure is simple and reasonably designed. The condensing mechanism includes a compressor and an exhaust pipe connected to the output end of the compressor. The exhaust pipe extends upward and is connected to an outlet pipe. The end of the outlet pipe away from the exhaust pipe is connected to the condenser. The evaporating mechanism includes a drying filter and a capillary tube disposed on one side of the drying filter. The condenser is located away from the outlet pipe. One end of the gas tube is connected to the dryer filter, and the two ends of the capillary tube are connected to the refrigerant inlet pipe and the refrigerant outlet pipe, respectively. The end of the refrigerant outlet pipe away from the capillary tube is connected to the evaporator. The compressor draws in the refrigerant in gaseous form, compresses the refrigerant into high-temperature and high-pressure superheated vapor, and discharges it from the exhaust pipe. Then it enters the condenser. Because the condenser has a large surface area, it is in full contact with the outside air, allowing the heat in the refrigerant to be dissipated to the surrounding air. The high-temperature and high-pressure gas is condensed into a low-temperature and high-pressure gas. Through the above steps, the temperature of the ship's internal compartment can be effectively increased, achieving a good dehumidification purpose.

[0015] 2. In this invention, after the refrigerant enters the capillary tube, due to its narrow and long channel, the refrigerant is throttled and depressurized, becoming a low-temperature, low-pressure liquid. The liquid then enters the evaporator and is vaporized. In the evaporator, the low-temperature, low-pressure refrigerant liquid absorbs a large amount of external heat and vaporizes into dry saturated vapor, achieving the purpose of absorbing heat from the outside and cooling, while also causing moisture to condense into water droplets and be discharged, thus quickly dehumidifying the ship's interior. This method is suitable for most ship cabin environments. Cooling and dehumidifying the air in this way is significantly more efficient than using drying methods, saving time and making it suitable for widespread use.

[0016] 3. The capillary tube in this utility model includes a main tube body, which is a hollow cavity structure with openings at both ends. Multiple flow-blocking baffles are fixed inside the cavity, distributed on both sides of the cavity and arranged crosswise. Each flow-blocking baffle includes a first inclined plate and a second inclined plate fixed to the first inclined plate. The end of the first inclined plate away from the second inclined plate is fixed to the inner wall of the cavity of the main tube body. A gap is provided between the second inclined plate and the inner wall of the cavity of the main tube body. By providing multiple crosswise flow-blocking baffles in each cavity of the main tube body, coupled with the slender nature of the main tube body itself, it is beneficial to obstruct the flow of refrigerant, slow down its flow rate, and greatly improve its pressure reduction efficiency. This can achieve better vaporization effect in the subsequent process, resulting in better dehumidification. Attached Figure Description

The compressor 31 is horizontally positioned, and the exhaust pipe 32 extends upward and is connected to an outlet pipe 33.

[0027] Working principle: Please refer to the following again. Figures 1 to 3 In the operation of this invention, the refrigerant is drawn into the compressor 31 in gaseous form, compressed, and discharged as high-temperature, high-pressure superheated vapor from the exhaust pipe 32. It then passes through the exhaust pipe 32 and the outlet pipe 33 into the condenser 34. Under the operation of the condenser 34, the refrigerant dissipates heat into the surrounding air, condensing from a high-temperature, high-pressure gas into a low-temperature, high-pressure gas. It then passes through the dryer filter 41 and enters the capillary tube 42. Upon entering the capillary tube 42, the refrigerant is obstructed due to its narrow passage. With the help of the baffle plate 422, it is throttled and depressurized, becoming a low-temperature, low-pressure liquid. It then enters the evaporator 45 and vaporizes. In the evaporator 45, the low-temperature, low-pressure refrigerant liquid absorbs a large amount of external heat and vaporizes into dry saturated vapor, thus achieving the purpose of absorbing heat from the outside for cooling. After the refrigerant becomes low-pressure superheated vapor in the suction pipe 46, it is drawn back into the compressor 31.
