Description

Technical Field

[0001] This utility model relates to the technical field of gas compressors, specifically to a raw material gas compressor. Background Technology

[0002] A raw gas compressor is a device used to compress gas and is the main component of a gas source system. It converts the mechanical energy of a prime mover (usually an electric motor) into gas pressure energy, and is the gas pressure generating device for compressed air. Air compressors are similar in construction to water pumps. Most raw gas compressors are reciprocating piston type, rotary vane, or rotary screw type. Of the electrical energy consumed by an air compressor, part is used to compress the gas and produce high-pressure air, while the other part is converted into heat energy, which is contained in the compressed air and lubricating oil.

[0003] Currently, the heat dissipation methods for existing feed gas compressors on the market are relatively simple and fixed. Most heat dissipation devices use a fixed heat dissipation cavity, and the capacity of the cooling medium cannot be adjusted according to actual operating conditions. When the feed gas temperature is high, the fixed heat dissipation cavity volume may not be able to hold enough cooling medium, resulting in limited heat dissipation area, low heat dissipation efficiency, and inability to dissipate heat in time, causing the feed gas temperature to continue to rise and affecting the normal operation of the compressor. Conversely, when the feed gas temperature is low, the fixed heat dissipation cavity will hold too much cooling medium, resulting in waste of cooling medium and increased equipment operating costs. Utility Model Content

[0004] This invention provides a raw material gas compressor that solves the problem in the prior art where the cooling medium capacity of the fixed-structure heat dissipation chamber cannot be adjusted according to actual working conditions.

[0005] This utility model provides a raw material gas compressor, including a compressor body, an outlet pipe, and a heat dissipation assembly. The outlet pipe is connected to the compressor body. The heat dissipation assembly includes a bracket, a first sleeve, a second sleeve, an inlet nozzle, and an outlet nozzle. The bracket is fixedly connected to the compressor body. The first sleeve is sleeved on the outside of the outlet pipe, and the second sleeve is sleeved on the outside of the first sleeve. The first sleeve is fixedly connected to the bracket, and one end of the first sleeve abuts against the outside of the outlet pipe. The second sleeve is slidably connected to the bracket, and one end of the second sleeve abuts against the outside of the first sleeve, and the other end of the second sleeve abuts against the outside of the outlet pipe. The inlet nozzle is fixedly connected to the side of the first sleeve, and the outlet nozzle is fixedly connected to the side of the second sleeve. A heat exchange chamber is provided between the first sleeve, the second sleeve, and the outlet pipe. Both the inlet nozzle and the outlet nozzle are connected to the heat exchange chamber.

[0006] According to one embodiment of this utility model, the bracket includes a connecting seat and a guide rod. The connecting seat is fixedly connected to the compressor body, and the guide rod is fixedly connected to the connecting seat along the axial direction of the air outlet pipe. The second sleeve has a guide hole that is slidably connected to the guide rod. The bracket also includes a limiting baffle, which is fixedly connected to the end of the guide rod away from the connecting seat. The bracket also includes an adjusting screw, which is rotatably connected to the connecting seat. The second sleeve has a threaded hole that is threadedly connected to the adjusting screw. The bracket also includes an adjusting handle, one end of which is coaxially fixedly connected to the adjusting screw, and the other end of which has a recessed groove with an internal hexagonal structure. The bracket also includes anti-slip ridges, which are arranged in a circular array on the side of the adjusting handle.

[0007] According to one embodiment of this utility model, a first sealing groove is formed on the inner side of the first sleeve near the support, and a first sealing ring is embedded in the first sealing groove. One side of the first sealing ring abuts against the first sleeve, and the other side of the first sealing ring abuts against the outer side of the air outlet pipe. A second sealing groove is formed on the outer side of the first sleeve away from the support, and a second sealing ring is embedded in the second sealing groove. One side of the second sealing ring abuts against the first sleeve, and the other side of the second sealing ring abuts against the second sleeve. A third sealing groove is formed on the inner side of the second sleeve near the support, and a third sealing ring is embedded in the third sealing groove. One side of the third sealing ring abuts against the second sleeve, and the other side of the third sealing ring abuts against the first sleeve. A fourth sealing groove is formed on the outer side of the second sleeve away from the support, and a fourth sealing ring is embedded in the fourth sealing groove. One side of the fourth sealing ring abuts against the second sleeve, and the other side of the fourth sealing ring abuts against the outer side of the air outlet pipe.

[0008] The advantages of this utility model compared to the prior art are: By circulating the cooling medium within the heat exchange chamber, the heat from the high-temperature raw material gas in the outlet pipe can be quickly and continuously removed, effectively reducing the temperature of the raw material gas. This ensures stable operation of the raw material gas compressor under suitable temperature conditions, improving the equipment's efficiency and reliability. The heat dissipation components adjust the volume of the heat exchange chamber according to changes in the raw material gas temperature. Increasing the volume when the raw material gas temperature is high enhances heat dissipation efficiency, while decreasing the volume when the temperature is low avoids wasting cooling medium. This adaptability allows the equipment to meet the heat dissipation requirements under different operating conditions, reducing energy consumption and operating costs.

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] like Figures 1 to 4As shown, a raw material gas compressor includes a compressor body 1, an outlet pipe 2, and a heat dissipation assembly 3. The outlet pipe 2 is connected to the compressor body 1. The heat dissipation assembly 3 includes a bracket 4, a first sleeve 5, a second sleeve 6, a liquid inlet 7, and a liquid outlet 8. The bracket 4 is fixedly connected to the compressor body 1. The first sleeve 5 is sleeved on the outside of the outlet pipe 2, and the second sleeve 6 is sleeved on the outside of the first sleeve 5. The first sleeve 5 is fixedly connected to the bracket 4, and one end of the first sleeve 5 abuts against the outside of the outlet pipe 2. The second sleeve 6 is slidably connected to the bracket 4, and one end of the second sleeve 6 abuts against the outside of the first sleeve 5. The other end of the second sleeve 6 abuts against the outside of the outlet pipe 2. The liquid inlet 7 is fixedly connected to the side of the first sleeve 5, and the liquid outlet 8 is fixedly connected to the side of the second sleeve 6. A heat exchange chamber 9 is provided between the first sleeve 5, the second sleeve 6, and the outlet pipe 2. The liquid inlet 7 and the liquid outlet 8 are both connected to the heat exchange chamber 9.

[0020] External cooling media (such as cooling water, heat transfer oil, etc.) are injected into heat exchange chamber 9 through inlet 7, thereby filling heat exchange chamber 9. When heat exchange chamber 9 is filled with cooling media, high-temperature raw material gas enters outlet pipe 2 from compressor body 1. The inner wall of outlet pipe 2 is in direct contact with high-temperature raw material gas, and heat is quickly transferred to the external cooling media through the pipe wall of outlet pipe 2, causing the temperature of the cooling media to rise. The heated cooling media is then discharged from heat exchange chamber 9 through outlet 8 and enters external cooling system (such as cooling tower, cooler) to cool down. The cooled cooling media can be injected into heat exchange chamber 9 again through inlet 7 to form a circulation flow, continuously carrying away the heat in outlet pipe 2.

[0021] When the raw material gas temperature is high, the second sleeve 6 can be slid away from the first sleeve 5 to increase the volume of the heat exchange chamber 9 to accommodate more cooling medium and improve the heat dissipation area and efficiency; when the raw material gas temperature is low, the second sleeve 6 can be slid closer to the first sleeve 5 to reduce the volume of the heat exchange chamber 9, avoid waste of cooling medium, and achieve flexible adaptation of heat dissipation capacity.

[0022] The circulating flow of the cooling medium within the heat exchange chamber 9 rapidly and continuously removes heat from the high-temperature raw material gas in the outlet pipe 2, effectively reducing the gas temperature and ensuring stable operation of the raw material gas compressor under suitable temperature conditions, thus improving equipment efficiency and reliability. The heat dissipation component 3 adjusts the volume of the heat exchange chamber 9 according to changes in the raw material gas temperature. Increasing the volume when the raw material gas temperature is high enhances heat dissipation efficiency, while decreasing the volume when the temperature is low avoids wasting cooling medium. This adaptability allows the equipment to meet the heat dissipation requirements under different operating conditions, reducing energy consumption and operating costs.

[0023] According to one embodiment of the present invention, the bracket 4 includes a connecting seat 10 and a guide rod 11. The connecting seat 10 is fixedly connected to the compressor body 1, and the guide rod 11 is fixedly connected to the connecting seat 10 along the axial direction of the air outlet pipe 2. The second sleeve 6 has a guide hole that is slidably connected to the guide rod 11. The bracket 4 also includes a limiting baffle 12, which is fixedly connected to the end of the guide rod 11 away from the connecting seat 10, thereby preventing the second sleeve 6 from sliding excessively and disengaging from the guide rod 11, thus forming a safety limit.

[0024] The bracket 4 further includes an adjusting screw 13, which is rotatably connected to the connecting seat 10. The second sleeve 6 has a threaded hole that is threadedly connected to the adjusting screw 13. The bracket 4 also includes an adjusting handle 14, one end of which is coaxially fixedly connected to the adjusting screw 13, and the other end of which has a recessed groove with an internal hexagonal structure. The bracket 4 also includes anti-slip ridges, a plurality of which are arranged in a circular array on the side of the adjusting handle 14.

[0025] When the volume of heat exchange chamber 9 needs to be adjusted, the operator drives the adjusting screw 13 to rotate by turning the adjusting handle 14. The adjusting screw 13 rotates and engages with the connecting seat 10, and also engages with the threaded hole of the second sleeve 6. The thread on the adjusting screw 13 converts the rotational motion into the linear motion of the second sleeve 6: when the adjusting handle 14 is turned clockwise, the adjusting screw 13 drives the second sleeve 6 to slide along the guide rod 11 toward the connecting seat 10 (i.e., toward the first sleeve 5), thus reducing the volume of heat exchange chamber 9; when the adjusting handle 14 is turned counterclockwise, the second sleeve 6 slides along the guide rod 11 away from the connecting seat 10 (i.e., away from the first sleeve 5), thus expanding the volume of heat exchange chamber 9.

[0026] In addition, the anti-slip protrusions on the side of the adjusting handle 14 can increase the friction of the hand and prevent slippage when rotating; the internal hexagonal groove design at the end of the handle can be adapted to use an internal hexagonal wrench to assist in rotation, making it easier to operate with force when the resistance of the adjusting screw 13 is large (such as the thread getting stuck after long-term use), ensuring a smooth adjustment process.

[0027] According to one embodiment of the present invention, a first sealing groove is provided on the inner side of the first sleeve 5 near the bracket 4, and a first sealing ring 15 is embedded in the first sealing groove. One side of the first sealing ring 15 abuts against the first sleeve 5, and the other side of the first sealing ring 15 abuts against the outer side of the air outlet pipe 2. The first sealing ring 15 fills the gap between the first sleeve 5 and the air outlet pipe 2 to prevent the cooling medium from leaking from the connection between the first sleeve 5 and the air outlet pipe 2.

[0028] A second sealing groove is formed on the outer side of the first sleeve 5 away from the support 4. A second sealing ring 16 is embedded in the second sealing groove. One side of the second sealing ring 16 abuts against the first sleeve 5, and the other side of the second sealing ring 16 abuts against the second sleeve 6. A third sealing groove is formed on the inner side of the second sleeve 6 near the support 4. A third sealing ring 17 is embedded in the third sealing groove. One side of the third sealing ring 17 abuts against the second sleeve 6, and the other side of the third sealing ring 17 abuts against the first sleeve 5. The two sides of the second sealing ring 16 and the third sealing ring 17 abut against the first sleeve 5 and the second sleeve 6 respectively, forming a double seal to prevent the cooling medium from leaking from the nested gap between the first sleeve 5 and the second sleeve 6.

[0029] A fourth sealing groove is provided on the outer side of the end of the second sleeve 6 away from the bracket 4. A fourth sealing ring 18 is embedded in the fourth sealing groove. One side of the fourth sealing ring 18 abuts against the second sleeve 6, and the other side of the fourth sealing ring 18 abuts against the outer side of the air outlet pipe 2. The fourth sealing ring 18 fills the gap between the second sleeve 6 and the air outlet pipe 2 to prevent the cooling medium from leaking from the connection between the second sleeve 6 and the air outlet pipe 2.

[0030] When the second sleeve 6 slides along the bracket 4 to adjust the volume, each sealing ring will deform synchronously with the movement of the sleeve. The sealing ring is made of elastic material (such as fluororubber and nitrile rubber), which can tightly fit the contact surface of the corresponding component. Even if the position of the second sleeve 6 changes, it can still maintain a stable sealing effect, ensuring that the cooling medium in the heat exchange chamber 9 only enters and exits through the inlet nozzle 7 and the outlet nozzle 8, without any risk of leakage.

[0031] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
