Description

Technical Field

[0001] The invention relates to the technical field of air compressors, and in particular to a heat exchange device for high-temperature gas at the rear end of a cylinder. Background Art

[0002] With the continuous advancement of industrial technology, reciprocating piston compressors, as important equipment for gas compression, have been widely used in many industries such as chemical industry, energy, and manufacturing. This type of compressor mainly achieves gas compression through the reciprocating motion of the piston in the cylinder. However, the high-temperature gas generated in this process may not only damage the components of the compressor itself, but also affect the normal operation of the downstream system. In order to solve these problems, the traditional approach is to use copper pipes combined with a water circulation system to heat and cool the high-temperature gas discharged from the rear end of the cylinder.

[0003] Specifically, this heat exchange device usually consists of a box and copper tubes installed inside. High-temperature gas passes through these copper tubes, and cooling water flows in the box to absorb and take away the heat of the high-temperature gas in the copper tubes. Although this method can effectively reduce the gas temperature to a certain extent, protect the equipment from high temperature, and maintain the stable operation of the downstream system, there are also some problems during long-term use.

[0004] First, the dust in the air and the oil produced when the compressor is working will accumulate on the inner wall of the copper tube over time, forming deposits that are difficult to remove. This layer of deposits will hinder the efficiency of heat transfer, resulting in a significant decrease in the performance of the heat exchange device originally designed for efficient heat dissipation. In the face of this situation, the traditional method is to disassemble the copper tube and use high-pressure water to flush to remove the deposits. However, this method is complicated to operate, and the cleaning effect is not ideal for those firmly attached oil and dust. In order to further solve the problem, it is usually necessary to use special chemical cleaning agents to assist in cleaning. Although chemical cleaning agents can partially remove stubborn stains, they often contain highly corrosive ingredients. Long-term use will cause irreversible corrosion to the inner wall of the copper tube. Once corrosion occurs, it is necessary to regularly detect the changes in the thickness of the inner wall of the copper tube. When the corrosion depth exceeds 3 mm, the corresponding copper tube parts must be replaced, which will increase maintenance costs and downtime. Summary of the invention

[0005] In view of this, the present invention provides a heat exchange device for high-temperature gas at the rear end of the cylinder, which can overcome the shortcomings of existing heat exchange devices that, when in use, difficult-to-remove deposits will form on the inner wall of the copper tube, thereby hindering the heat transfer efficiency, usually requiring disassembly and cleaning, which is cumbersome to operate, and may require the aid of special chemical cleaning agents to assist in cleaning, which may cause the copper tube to be corroded and need to be replaced.

Since the first rubber ball 8 and the second rubber ball 10 are both close to the inner wall of the copper tube 4, the waste water generated by flushing the inner wall of the copper tube 4 will be concentrated between the first rubber ball 8 and the second rubber ball 10, and enter the first rubber ball 8 through the channel 801. At the same time, the front water pump 21 can extract the waste water inside the first rubber ball 8 through the front infusion pipe 2101, the front winding wheel 15 and the first connecting pipe 12, and can transport the waste water to the waste liquid tank 20 for collection through the drainage pipe 22.

[0039] When the first rubber ball 8 enters the inside of the copper tube 4 from the rear end of the copper tube 4, the first rubber ball 8 will drive the second magnetic ring 41 to move to the left close to the first magnetic ring 40 at the rear side. The second magnetic ring 41 can pull the first magnetic ring 40 at the rear side to move to the left through the magnetic force, and drive the sliding tube 39 at the rear side to move to the left, so that the through hole 3901 on the sliding tube 39 at the rear side is no longer connected to the intake pipe 5, and the sliding tube 39 at the rear side blocks the lower end of the intake pipe 5. In this way, when the first rubber ball 8 pushes the sediment on the inner wall of the copper tube 4 toward the front end of the copper tube 4, the sediment is prevented from entering the intake pipe 5 through the through hole 3901 on the sliding tube 39 at the rear side, and the The water sprayed from the first nozzle 11 is prevented from entering the air inlet pipe 5. Similarly, when the first rubber ball 8 is about to be pulled out of the front end of the copper tube 4, the first rubber ball 8 can drive the first magnetic ring 40 on the front side and the sliding tube 39 on the front side to move to the right through the second magnetic ring 41, so that the sliding tube 39 on the front side blocks the lower end of the air outlet pipe 6, thereby preventing sediment and water from entering the air outlet pipe 6. When the first rubber ball 8 moves along the inside of the copper tube 4 back to the inside of the installation tube 7, the first rubber ball 8 can drive the two sliding tubes 39 to slide in the opposite direction and reset through the second magnetic ring 41, so that the through holes 3901 on the two sliding tubes 39 can be respectively connected with the air inlet pipe 5 and the air outlet pipe 6 again.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
