Description

Technical Field

[0001] This utility model belongs to the field of air compressor dewatering technology, specifically relating to a dewatering structure for the downstream pipeline of an air compressor used in a mixing plant. Background Technology

[0002] In the construction industry, the normal operation of a batching plant depends on the compressed air provided by an air compressor to drive various pneumatic equipment, such as the pneumatic valves of the concrete mixer and the pneumatic actuators of the batching machine. The compressed air discharged by the air compressor usually contains a certain amount of water vapor. The state of these water vapors is closely related to the ambient temperature. In summer or high-temperature environments, due to the high ambient temperature, the water vapor in the compressed air is not easy to condense into liquid water, and the impact on pneumatic equipment and pipelines is small. Generally, it will not affect the normal operation of the batching plant. However, in winter or low-temperature environments, the situation is significantly different. When the compressed air flows through the subsequent pipelines, it is affected by the low temperature environment, and the water vapor in it will quickly condense into liquid water.

[0003] As the amount of condensed water in compressed air increases in low-temperature environments, a series of problems will arise. On the one hand, the accumulation of liquid water in the pipes will cause corrosion of the pipe walls, shortening the service life of the pipes. At the same time, impurities produced by corrosion may enter the pneumatic equipment with the compressed air, causing wear and jamming, affecting the normal operation accuracy and stability of the equipment, and increasing the maintenance cost and failure rate of the equipment. On the other hand, when the ambient temperature is below the freezing point, the accumulated liquid water will freeze, which can easily cause pipe blockage, preventing the compressed air from being delivered to the pneumatic equipment normally. In severe cases, it can interrupt the production of the mixing plant and affect the progress of the project.

[0004] To address the aforementioned issues, existing technologies typically employ a dryer between the air compressor and the pneumatic equipment to remove moisture from the compressed air. However, when existing dryers directly process the compressed air discharged from the air compressor, the untreated compressed air contains a large amount of water vapor, especially in low-temperature winter conditions. A large amount of condensate directly enters the dryer, significantly reducing its efficiency and drying effect. This results in the dried compressed air still containing a significant amount of moisture, failing to meet the dryness requirements of the pneumatic equipment in the mixing plant and failing to fundamentally solve the problems of pipe icing and equipment damage.

[0005] Therefore, in response to the problem of water accumulation and freezing in the downstream pipelines of the air compressor in the mixing plant under low-temperature conditions in winter, how to improve the dryness of compressed air through structural improvements based on the existing dryer dehydration has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a water removal structure for the downstream pipeline of an air compressor in a mixing plant, which can significantly improve the drying degree of the gas by the downstream dryer, effectively avoid water accumulation and freezing in the pipeline and equipment corrosion and jamming in low winter temperatures, reduce maintenance costs, and ensure the stable operation of pneumatic equipment in the mixing plant.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A dewatering structure for the downstream pipeline of an air compressor used in a mixing plant includes an air compressor, a first pipeline at the port of the air compressor, a second pipeline and a third pipeline connected to the first pipeline, a dryer installed between the second pipeline and the third pipeline, and a pre-dewatering structure provided on the outside of the second pipeline.

[0009] A first solenoid valve is installed on the first pipe and located between the second pipe and the third pipe, and a second solenoid valve and a third solenoid valve are respectively installed on the second pipe and the third pipe.

[0010] The pre-dehydration structure includes an inner side plate, which is attached to the outside of the second pipe, and multiple heating elements are attached to the outside of the inner side plate.

[0011] An outer side plate is fixed to the outer side of the inner side plate via a base plate. Multiple mounting shells are fixed to the outer side of the outer side plate, and a fan is installed inside each mounting shell.

[0012] The base plate has through holes evenly distributed inside.

[0013] Both the inner and outer side plates have notches at their bottoms.

[0014] The second pipe is connected to a spiral tube in the middle, and the inner side plate is attached to the outer side of the spiral tube.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This invention adds a pre-drying structure before the dryer, which removes most of the liquid water in the compressed air, turning it into water vapor, before it enters the dryer. This significantly improves the drying effect of the subsequent dryer on the gas, effectively avoids water accumulation and freezing in pipes and equipment corrosion and jamming in low winter temperatures, reduces maintenance costs, ensures stable operation of pneumatic equipment in the mixing plant, and is adaptable to different working conditions in winter and summer, making it highly practical.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4 As shown, a dewatering structure for the downstream pipeline of an air compressor in a mixing plant includes an air compressor 1. A first pipeline 2 is installed at the port of the air compressor 1. A second pipeline 3 and a third pipeline 5 are connected to the first pipeline 2. A dryer 4 is installed between the second pipeline 3 and the third pipeline 5. A pre-dewatering structure is installed on the outside of the second pipeline 3. (Refer to the attached diagram.) Figure 1 A first solenoid valve 6 is installed on the first pipe 2 and between the second pipe 3 and the third pipe 5. A second solenoid valve 7 and a third solenoid valve 8 are installed on the second pipe 3 and the third pipe 5, respectively.

[0025] In summer, when the air compressor 1 is working, the second solenoid valve 7 and the third solenoid valve 8 are closed to prevent gas from moving towards the second pipe 3 and the third pipe 5, while the first solenoid valve 6 is opened, so that the gas only flows in the first pipe 2. This allows the gas produced by the air compressor 1 to be guided through the first pipe 2. In winter, when the air compressor 1 is working, the second solenoid valve 7 and the third solenoid valve 8 are opened, and the first solenoid valve 6 is closed, thus closing the first pipe 2 while allowing the second pipe 3 and the third pipe 5 to be open. This allows the gas in the air compressor 1 to be transferred from the second pipe 3 to the dryer 4, where the dryer 4 dries the moisture in the air. The gas is then transferred to the first pipe 2 through the third pipe 5, thus removing the moisture from the gas and preventing moisture from causing corrosion or freezing of subsequent pipes.

[0026] See attached document Figure 3 and attached Figure 4 The pre-dehydration structure includes an inner side plate 11, which is attached to the outside of the second pipe 3. Multiple heating elements 12 are attached to the outside of the inner side plate 11, heating the inner side plate 11 and transferring the temperature to the second pipe 3. This allows the second pipe 3 to evaporate as much moisture as possible into gas, facilitating the gas's movement into the dryer 4 and increasing the dryness of the gas. The inner side plate 11 is made of a heat-conducting material, such as metal like iron or copper. A spiral tube 9 is connected to the middle of the second pipe 3. This spiral tube 9 is detachably mounted on the second pipe 3 and can be fixed by insertion, snap-fit, or threaded connection. The inner side plate 11 is attached to the outside of the spiral tube 9, extending the gas's travel length within the second pipe 3 and improving the heating effect of the heating elements 12.

[0027] To prevent the heating element 12 from being damaged by rain or other impacts, please refer to the attached document. Figure 3 and attached Figure 4 An outer side plate 10 is fixed to the outer side of the inner side plate 11 via a base plate 16. The outer side plate 10 protects the heating element 12. Multiple mounting shells 14 are fixed to the outer side of the outer side plate 10, and a fan 15 is installed in each mounting shell 14. The fan 15 can remove heat between the outer side plate 10 and the inner side plate 11, preventing the heating element 12 from being damaged due to overheating. Furthermore, through holes 17 are evenly arranged inside the base plate 16, which connect the space inside the outer side plate 10 with the outside, preventing negative pressure from the space between the outer side plate 10 and the inner side plate 11 when the fan 15 is drawing heat. Furthermore, notches 13 are provided at the bottom of both the inner side plate 11 and the outer side plate 10, allowing the second pipe 3 to be installed inside the inner side plate 11.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
