Description

Technical Field

[0001] This application relates to the field of auxiliary equipment technology for nitrogen compressors, and in particular to a cooling device for a nitrogen compressor. Background Technology

[0002] A nitrogen compressor is the core equipment for compressing nitrogen gas from atmospheric pressure to high pressure. During the compression process, nitrogen gas will experience a significant temperature rise due to the conversion of mechanical energy into heat energy. The higher the compression ratio, the higher the temperature, which can reach up to 180°C. If the high-temperature nitrogen gas is not cooled in time, it will cause multiple problems.

[0003] While current cooling devices generally employ water cooling, the cooling water contains minerals such as calcium and magnesium ions. During long-term circulation, these minerals are easily precipitated and gradually deposited on the outer wall of the cooling tube bundle due to the temperature difference between the inside and outside of the cooling tube bundle and changes in water flow rate. This forms a dense scale layer, which significantly increases thermal resistance and leads to a significant decrease in the heat exchange efficiency between the cooling water and high-temperature nitrogen gas, thus affecting the cooling effect. To address this issue, we propose a cooling device for nitrogen compressors. Utility Model Content

[0004] The purpose of this application is to provide a cooling device for a nitrogen compressor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cooling device for a nitrogen compressor includes a compressor. A connecting pipe is connected to the front of the compressor. A sealed shell is embedded in the outer surface of the connecting pipe. A temperature sensor is installed on the inner wall of the sealed shell. One side of the sealed shell is connected to the front of the compressor. A motor is installed on the bottom surface of the sealed shell. A threaded rod is fixedly connected to the output end of the motor. The top end of the threaded rod extends into the interior of the sealed shell. A movable plate is threadedly connected to the outer surface of the threaded rod. A set of cleaning rings is embedded in the inner side of the movable plate. Each cleaning ring is sleeved on the outside of the connecting pipe.

[0007] In a further embodiment, the upper surface of the sealed shell is connected to a water inlet pipe, and the bottom surface of the sealed shell is connected to a drain pipe.

[0008] In a further embodiment, a filter screen is fixedly connected to the inner wall of the sealed shell, and the filter screen is rotatably connected to the threaded rod.

[0009] In a further embodiment, a cleaning groove is provided on the front of the sealed shell, and a sealing block is provided inside the cleaning groove.

[0010] In a further embodiment, reinforcing plates are fixedly connected to both the left and right sides of the sealed shell, and the rear end of each reinforcing plate is connected to the front of the compressor.

[0011] In a further embodiment, the inner wall of each cleaning ring is provided with multiple layers of elastic scrapers.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This application utilizes a motor, threaded rod, moving plate, and cleaning ring in a coordinated manner. The motor drives the threaded rod to rotate, while the moving plate moves the cleaning ring outside the connecting pipe, thus cleaning the scale on the outside of the connecting pipe. This ensures the heat exchange efficiency between the cooling water and high-temperature nitrogen, further guaranteeing the cooling effect. The combination of a filter screen, cleaning tank, and sealing block allows for the collection and diversion of the removed scale, facilitating centralized processing by staff.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] 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.

[0020] Please see Figure 1-3 In this utility model, a cooling device for a nitrogen compressor includes a compressor 1. A connecting pipe 4 is connected to the front of the compressor 1. A sealed shell 3 is embedded on the outer surface of the connecting pipe 4. A temperature sensor 12 is installed on the inner wall of the sealed shell 3. The temperature sensor 12 can detect the water temperature inside the sealed shell 3 in real time, so that the staff can replace the cooling water in time. A water inlet pipe 2 is connected to the upper surface of the sealed shell 3, and a drain pipe 14 is connected to the bottom surface of the sealed shell 3. The cooperation of the water inlet pipe 2 and the drain pipe 14 not only makes it convenient for the staff to inject water into the sealed shell 3, but also makes it convenient for the staff to drain water from the drain pipe 14.

[0021] Reinforcing plates 6 are fixedly connected to both the left and right sides of the sealed shell 3. The rear end of each reinforcing plate 6 is connected to the front of the compressor 1. The reinforcing plates 6 can be used to connect the sealed shell 3 and the compressor 1, thereby improving the robustness of the sealed shell 3.

[0022] One side of the sealed shell 3 is connected to the front of the compressor 1. A motor 10 is installed on the bottom of the sealed shell 3. A threaded rod 8 is fixedly connected to the output end of the motor 10. The top of the threaded rod 8 extends into the interior of the sealed shell 3. A movable plate 7 is threadedly connected to the outer surface of the threaded rod 8. A set of cleaning rings 11 are embedded on the inner side of the movable plate 7. Each cleaning ring 11 is sleeved on the outside of the connecting pipe 4. When the motor 10 is controlled to work, the motor 10 will drive the threaded rod 8 to rotate, and the movable plate 7 will move on the threaded rod 8. At the same time, the cleaning rings 11 will move synchronously on the outside of the connecting pipe 4, which can remove the scale formed on the outside of the connecting pipe 4, thereby ensuring the heat exchange efficiency between the cooling water and the high-temperature nitrogen, and further ensuring its cooling effect. The inner wall of each cleaning ring 11 is provided with multiple layers of elastic scrapers. The elastic scrapers can prevent friction between the cleaning ring 11 and the connecting pipe 4, so as to avoid leakage of the connecting pipe 4.

[0023] A filter screen 9 is fixedly connected to the inner wall of the sealed shell 3, and the filter screen 9 is rotatably connected to the threaded rod 8. The filter screen 9 can be used to collect the scale after cleaning, preventing it from accumulating at the bottom of the sealed shell 3. A cleaning groove 13 is provided on the front of the sealed shell 3. A sealing block 5 is provided inside the cleaning groove 13. By opening the sealing block 5, the collected scale can be processed from the cleaning groove 13, which greatly facilitates the descaling work of the staff.

[0024] The working principle of this application is as follows: When the compressor 1 is working, cooling water can be injected into the sealed shell 3. When the compressed gas flows inside the connecting pipe 4, the cooling water can cool the connecting pipe 4. After cooling for a long time, the control motor 10 is turned on, and the motor 10 will drive the threaded rod 8 to rotate. The moving plate 7 will move on the threaded rod 8, and at the same time, the cleaning ring 11 will move synchronously outside the connecting pipe 4, which can remove the scale formed on the outside of the connecting pipe 4, thereby ensuring the heat exchange efficiency between the cooling water and the high-temperature nitrogen gas, and further ensuring the cooling effect.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
