Description

Technical Field

[0001] This utility model belongs to the field of cold energy recovery, and specifically relates to a cold energy recovery device. Background Technology

[0002] BOG refers to the vaporized gas produced during the storage, transportation, and processing of liquefied natural gas (LNG). LNG has only about 45% the mass of an equal volume of water. Its manufacturing process involves purifying natural gas produced from gas fields, followed by a series of cryogenic liquefaction processes, and then transporting it using LNG ships. Due to the enormous amount of cold energy contained in LNG, it plays an important role in current social production and daily life. Given the relatively tight global energy reserves and the continuous increase in LNG sales, the rational use of LNG cold energy is particularly important.

[0003] Current ice-making equipment is generally driven by electrical and mechanical energy, which consumes a lot of electricity. Therefore, we need to consider how to make reasonable use of the cold energy generated during the gasification of liquefied natural gas. In addition, because the temperature inside the container is very low, it is quite troublesome to remove ice after it is made.

[0004] To address the aforementioned issues, Chinese patent CN223050268U discloses a BOG cold energy recovery device. This prior art removes ice blocks by moving a partition up and down. However, when removing the ice blocks, it is inconvenient to manually remove them from above the partition. Utility Model Content

[0005] To address the shortcomings of the existing technology, the present invention aims to provide a cold energy recovery device. This device is equipped with a vertical sealing plate. By controlling the movement of the sealing plate, the ice-retrieving device can be moved, thereby removing ice blocks from the ice mold shell. The ice blocks fall downwards under the action of gravity, thus being recovered. This makes the device more convenient to use. In addition, the ice mold shell is located on both sides of the vaporizer, which is more conducive to the recovery of cold energy.

[0006] The technical solution adopted by this cold energy recovery device to solve its technical problem is as follows:

[0007] A cold energy recovery device is provided, including a housing with supporting legs fixedly installed on the bottom surface of the housing. A connecting pipe passes through the housing, and a vaporizer is fixedly installed on the connecting pipe. The housing has openings on both sides, and sealing plates are respectively provided on both sides of the housing. A moving device is provided on the housing to drive the two sealing plates to move left and right. Two movable plates are provided inside the housing, and an installation structure is provided inside the housing for installing the housing. Several evenly distributed ice mold shells are fixedly installed on the opposite side of the movable plates. The side of the ice mold shells closest to the sealing plates is open and makes sealing contact with the sealing plates. Water inlet structures are provided on the opposite side of the sealing plates, and ice-removing devices are provided on the opposite side of the sealing plates.

[0008] Furthermore, the moving device includes several electric actuators, which are fixedly installed on the top and bottom surfaces of the housing, and the movable ends of the electric actuators are respectively fixedly connected to corresponding sealing plates.

[0009] Furthermore, the installation structure includes several spring telescopic rods. The fixed ends of the spring telescopic rods are fixedly installed on the top and bottom surfaces of the inner wall of the box via mounting brackets, and the movable ends of the spring telescopic rods are fixedly connected to the opposite surfaces of the corresponding movable plates.

[0010] Furthermore, the water inlet structure includes several water inlet pipes, connecting pipes, and flexible hoses. The several water inlet pipes pass through the sealing plate and are fixedly and sealed together. The water inlet pipes are interconnected with the corresponding ice mold shells. The water inlet pipes are connected to and interconnected with the connecting pipes. The flexible hoses are connected to and interconnected with the connecting pipes.

[0011] Furthermore, a tee pipe is provided at the connection between the hose and the connecting pipe. The two ends of the tee pipe are respectively fixedly connected to the hose and the connecting pipe. A shut-off valve is fixedly installed at the open end of the tee pipe and the connection end with the hose. A drain pipe with a shut-off valve is fixedly connected to the bottom of the connecting pipe and they are interconnected.

[0012] Furthermore, the ice-retrieving device includes a U-shaped pull rod with sealing plates fixedly connected to both ends, and the pull rod is located in the upper part of the corresponding ice mold shell.

[0013] Furthermore, collection boxes with top openings are respectively provided on both sides of the box body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model exemplifies a cold energy recovery device. The device is used for the recovery and utilization of cold energy. First, the user adds water to the ice mold shell through a water inlet device. Second, the user adds liquefied natural gas into a connecting pipe. The liquefied natural gas vaporizes as it passes through the vaporizer, absorbing heat and generating cold energy. This cold energy freezes the water inside the ice mold shell into ice blocks. Third, a moving device controls two sealing plates to move in opposite directions, allowing an ice-removing device to extract the ice blocks from the ice mold shell. Compared to existing technologies, this utility model features vertical sealing plates. Controlling the movement of these plates moves the ice-removing device, enabling the ice blocks to be extracted from the ice mold shell. The ice blocks fall downwards under gravity for recovery, making it more convenient to use. Furthermore, the ice mold shell is located on both sides of the vaporizer, further facilitating cold energy recovery.

[0016] 2. The present invention provides a cold energy recovery device that can control the movement of a sealing plate in the left and right directions by controlling the extension and retraction of an electric push rod. The moving device has a simple structure and is easy to use.

[0017] 3. In one example of the cold energy recovery device of this utility model, the spring telescopic rod can apply an outward force to the movable plate, thereby enabling the ice mold shell to fit tightly with the sealing plate.

[0018] 4. A cold energy recovery device according to this utility model connects a hose to the outlet of an existing water pumping device. The water pumping device can pump water along the hose, connecting pipe and inlet pipe into different ice mold shells. The hose can bend as the sealing plate moves, making it convenient to use.

[0019] 5. A cold energy recovery device according to this utility model example closes the shut-off valves on the drain pipe and the opening end, and opens the shut-off valve at the hose. The user can add water into the ice mold shell. After adding water, the shut-off valves on the drain pipe and the opening end are opened, and the shut-off valve at the hose is closed, so that the water in the drain pipe can be discharged, thereby preventing the water in the connecting pipe and the water inlet pipe from freezing.

[0020] 6. In a cold energy recovery device according to this utility model, when the sealing plate is separated from the ice film shell, the sealing plate can drive the pull rod to move relative to the ice film shell, thereby removing the ice block inside the ice film shell.

[0021] 7. A cold energy recovery device according to this utility model example has a collection box that can collect ice cubes, making it more convenient to use. Attached Figure Description

[0027] like Figure 1 As shown, a cold energy recovery device includes a housing 1, with supporting legs 2 fixedly installed on the bottom surface of the housing 1. A connecting pipe 3 passes through the housing 1, and a vaporizer 4 is fixedly installed on the connecting pipe 3. The housing 1 has openings on both sides, and sealing plates 5 are respectively provided on both sides of the housing 1. Sealing gaskets are fixedly installed on the opposite sides of the sealing plates 5. A moving device is provided on the housing 1 to move the two sealing plates 5 left and right.

Several evenly distributed ice mold shells 7 are fixedly installed on the opposite sides of the movable plates 6. The ice mold shells 7 are cuboid in shape and made of a cold-conducting material. The side of the ice mold shell 7 closest to the sealing plate 5 is open and makes a sealing contact with the sealing plate 5. A water inlet structure is provided on the opposite sides of the sealing plate 5, and an ice-removing device is provided on the opposite side of the sealing plate 5. This invention relates to the recovery and utilization of cold energy. First, the user adds water to the ice mold shell 7 through the water inlet device. Second, the user adds liquefied natural gas into the connecting pipe 3. As the liquefied natural gas passes through the vaporizer, it vaporizes, absorbing heat and generating cold energy. This cold energy freezes the water inside the ice mold shell 7 into ice blocks. Third, the two sealing plates 5 are moved in opposite directions by a moving device, allowing the ice-removing device to extract the ice blocks from the ice mold shell 7. Compared to existing technologies, this invention features vertical sealing plates 5. By controlling the movement of the sealing plates 5, the ice-removing device can move, thus extracting the ice blocks from the ice mold shell 7. The ice blocks fall downwards under gravity for recovery, making it more convenient to use. Furthermore, the ice mold shell 7 is located on both sides of the vaporizer 4, which further facilitates the recovery of cold energy.

[0028] like Figure 1As shown, in a further preferred embodiment, the moving device includes several electric actuators 8, which are telescopically controlled. A power source for supplying power to the electric actuators 8 is provided on the housing 1. The electric actuators 8 are fixedly installed on the top and bottom surfaces of the housing 1, and their movable ends are respectively fixedly connected to corresponding sealing plates 5. By controlling the telescopic movement of the electric actuators 8, the sealing plates 5 can be moved in the left-right direction. This moving device has a simple structure and is easy to use.

[0029] like Figure 1 As shown, in a further preferred embodiment, the installation structure includes several spring telescopic rods 9. Each spring telescopic rod 9 has an internal spring structure. The fixed ends of the spring telescopic rods 9 are fixedly installed on the top and bottom surfaces of the inner wall of the housing 1 via mounting brackets. The movable ends of the spring telescopic rods 9 are fixedly connected to the opposite surfaces of the corresponding movable plates 6. The spring telescopic rods 9 can apply an outward force to the movable plates 6, thereby ensuring a tight fit between the ice mold shell 7 and the sealing plate 5.

[0030] like Figure 1 As shown, in a further preferred embodiment, the water inlet structure includes several water inlet pipes 10, connecting pipes 11, and flexible hoses 12. The water inlet pipes 10 pass through the sealing plate 5 and are fixedly and sealed together. Each water inlet pipe 10 communicates with a corresponding ice mold shell 7. Each water inlet pipe 10 is connected to and communicates with the connecting pipe 11. The flexible hose 12 is connected to and communicates with the connecting pipe 11. The flexible hose 12 is connected to the outlet of an existing pumping device, allowing the pumping device to guide water along the flexible hose 12, connecting pipe 11, and water inlet pipes 10 into different ice mold shells 7. The flexible hose 12 can bend as the sealing plate 5 moves, making it convenient to use.

[0031] like Figure 1 As shown, in a further preferred embodiment, a tee pipe is provided at the connection between the flexible hose 12 and the connecting pipe 11. The two ends of the tee pipe are respectively fixedly connected to the flexible hose 12 and the connecting pipe 11. A shut-off valve is fixedly installed at the open end of the tee pipe and at the connection end with the flexible hose 12. A drain pipe with a shut-off valve is fixedly connected to the bottom of the connecting pipe 11 and they are interconnected. The inlet pipe 10 adopts a structure design with a higher inner side and a lower outer side, facilitating the drainage of water from the inlet pipe 10 during drainage. By closing the shut-off valves on the drain pipe and at its open end, and opening the shut-off valve at the flexible hose 12, the user can add water to the ice mold shell 7. After adding water, opening the shut-off valves on the drain pipe and at its open end, and closing the shut-off valve at the flexible hose 12, allows the water in the drain pipe to be drained, thereby preventing the water in the connecting pipe 11 and the inlet pipe 10 from freezing.

[0032] like Figure 1As shown, in a further preferred embodiment, the ice-removing device includes a U-shaped pull rod 13. The pull rod 13 has a U-shaped structure when viewed from above, with its opening facing the sealing plate 5. Both ends of the pull rod 13 are fixedly connected to the sealing plate 5, and the pull rod 13 is located in the upper part of the corresponding ice mold shell 7. When the sealing plate 5 separates from the ice mold shell 7, the sealing plate 5 can drive the pull rod 13 to move relative to the ice mold shell 7, thereby removing the ice from the ice mold shell 7.
