Description

Technical Field

[0001] The present application relates to the technical field of compressed air treatment, and in particular to a condensate discharge control method and device for compressed air. Background Art

[0002] Compressed air systems are widely used in industrial production and daily life, such as pneumatic tools, automation control, food processing and other fields. However, since compressed air contacts the pipe wall during transportation, condensed water is easily generated. Condensed water not only contains water, but also carries impurities, oil stains, rust products and other pollutants in the pipeline. If not removed in time, these condensed water will seriously affect the quality of compressed air, and then affect the quality of the final product and the service life of the equipment.

[0003] In existing compressed air systems, condensate is usually discharged manually or automatically at a scheduled time. Manual discharge is inefficient, while scheduled discharge may result in premature or late discharge, resulting in resource waste or system pollution. In addition, the discharge process may generate loud noise, and in cold environments, condensate in the pipe may freeze, causing equipment damage. Summary of the invention

[0004] In view of the above, it is necessary to provide a condensate discharge control method and device for compressed air that can control condensate discharge, reduce noise, and prevent freezing.

[0005] The present application provides a method for controlling condensate discharge of compressed air, the method comprising:

[0006] Set up a water storage and drainage tank at the low point of the compressed air pipeline;

[0007] The condensed water in the pipeline is introduced into the storage and drainage tank through the water inlet port;

[0008] Direct the dirt and rust residue in the condensed water into the dirt storage area;

[0009] When the condensed water in the storage and drainage tank reaches the preset water level, the water level monitoring system triggers the drainage solenoid valve to drain the water;

[0010] After drainage is completed, close the drainage solenoid valve to balance the pressure in the drainage tank with the pipeline pressure, and restore the normal operation of the compressed air pipeline.

[0011] In a possible implementation, the control method further includes:

[0012] During the drainage process, pressure is added to the water storage and drainage tank through the leakage hole on the buffer valve at the water inlet port to reduce noise during the drainage process and speed up the drainage.

[0013] In a possible implementation, after the water level in the water storage and drainage tank drops to a preset low level, the drainage solenoid valve is closed through a water level monitoring system;

[0014] The water level monitoring system includes a low water level sensing switch, a high water level sensing switch and a water level sensor. The low water level sensing switch, the high water level sensing switch and the water level sensor are all fixedly installed inside the water storage and drainage tank body. The low water level sensing switch is located at the top of the drainage pipe of the water storage and drainage tank body, and the high water level sensing switch is located at the bottom of the water inlet pipe of the water storage and drainage tank body.

[0015] In a possible implementation, the control method further includes:

[0016] A dirt separation structure is set up inside the storage and drainage tank to collect the deposited dirt and rust residue, and remove them regularly through the sewage port;

[0017] The dirt separation structure includes a partition and a drain pipe, the partition is fixedly installed on the inner wall of the storage and drainage tank body, the gap between the bottom of the partition and the interior of the storage and drainage tank body forms a dirt storage area, the drain pipe is fixedly installed inside the storage and drainage tank body, one end of the drain pipe is connected to the dirt storage area, and a top cover is installed on the other end of the drain pipe, a second discharge hole is opened inside the partition, and a mounting piece is fixedly installed inside the partition, the mounting piece is a hollow arched cylinder, and a first discharge hole is opened at one end of the mounting piece.

[0018] In a possible implementation, the control method further includes:

[0019] When the external ambient temperature is lower than the preset threshold, the temperature control device is activated to heat the storage and drainage tank to prevent ice from damaging the equipment.

[0020] In a possible implementation, the control method further includes:

[0021] The amount of condensed water discharged each time is recorded by the discharge metering device, and the working parameters of the drainage device are adjusted accordingly to ensure the quality of compressed air.

[0022] In a possible implementation, the control method further includes:

[0023] An emergency exhaust switch is installed on the storage and drainage tank body. When sewage cannot enter the storage and drainage tank body, the emergency exhaust switch is manually opened to ensure smooth drainage.

[0024] In a possible implementation, the control method further includes:

[0025] An inspection port is set on the storage and drainage tank to regularly check the situation inside the tank and remove accumulated dirt and rust.

[0026] In a possible implementation, the control method further includes:

[0027] Control function switches and display devices are set on the external protection storage and drainage tank body to monitor and control the entire drainage process and display the equipment status.

[0028] In a possible implementation, a condensate discharge control device for compressed air is applicable to any of the methods described above.

[0029] In the above-mentioned condensate discharge control method and device for compressed air, by setting up a water level monitoring system, real-time monitoring of the condensate level in the storage and drainage tank is achieved. When the water level reaches the preset value, the drainage solenoid valve is automatically triggered for discharge, thereby avoiding the inconvenience caused by manual operation and the inaccuracy of timed discharge. When the outside temperature is lower than the preset threshold, the temperature control device automatically starts the heating protection function to prevent the condensate from freezing and causing damage to the equipment, thereby improving the reliability of the system. During the drainage process, the pressure is supplemented to the storage and drainage tank through the leakage hole on the buffer valve of the water inlet port, which effectively reduces the noise generated during the discharge process and improves the working environment.

[0030] The amount of condensed water discharged each time is recorded by the discharge metering device, and the working parameters of the drainage device are adjusted accordingly to ensure that the quality of compressed air is always in the best state.

[0031] Inspection ports and emergency exhaust switches are set on the storage and drainage tanks to facilitate regular inspection of the tank conditions and removal of accumulations. Manual intervention is also possible in abnormal situations, ensuring long-term and stable operation of the equipment.

[0032] The control function switches and display devices on the external protection storage and drainage tank allow staff to check the equipment status at any time and make necessary operational adjustments, enhancing the operability and transparency of the system.

[0044] Based on this, an embodiment of the present application provides a condensate discharge control method for compressed air, aiming to control condensate discharge and reduce noise.

[0045] See also Figure 1-Figure 6 This embodiment provides a technical solution: the method includes:

[0046] A water storage and drainage tank 1 is provided at the low point of the compressed air pipeline;

[0047] The condensed water in the pipeline is introduced into the storage and drainage tank body 1 through the water inlet port 2;

[0048] The dirt and rust residue in the condensed water are introduced into the dirt storage area 4;

[0049] When the condensed water in the storage and drainage tank 1 reaches the preset water level, the drainage solenoid valve 3 is triggered by the water level monitoring system to drain the water;

[0050] After the drainage is completed, the drainage solenoid valve 3 is closed to balance the pressure in the drainage tank 1 with the pipeline pressure, and the normal operation of the compressed air pipeline is restored.

[0051] In some embodiments, the control method further includes:

[0052] During the drainage process, pressure is added to the water storage and drainage tank body 1 through the leakage hole on the buffer valve of the water inlet port 2, so as to reduce the noise during the drainage process and speed up the drainage speed.

[0053] After the water level in the water storage and drainage tank 1 drops to a preset low level, the drainage solenoid valve 3 is closed through the water level monitoring system;

[0054] The water level monitoring system includes a low water level sensing switch 5, a high water level sensing switch 6 and a water level sensor 7. The low water level sensing switch 5, the high water level sensing switch 6 and the water level sensor 7 are all fixedly installed inside the water storage and drainage tank body. The low water level sensing switch 5 is located at the top of the drain pipe, and the high water level sensing switch 6 is located at the bottom of the water inlet pipe.

[0055] By providing a low water level sensing switch 5, a high water level sensing switch 6 and a water level sensor 7, the water level inside the water storage and drainage tank can be sensed and detected.

[0056] The method further comprises:

[0057] A dirt separation structure is provided in the storage and drainage tank 1 to collect the deposited dirt and rust residue, and remove them regularly through the sewage discharge port;

[0058] The dirt separation structure includes a partition 8 and a drain pipe, the partition 8 is fixedly installed on the inner wall of the storage and drainage tank body, the gap between the bottom of the partition 8 and the inside of the storage and drainage tank body forms a dirt storage area 4, the drain pipe is fixedly installed inside the storage and drainage tank body, one end of the drain pipe is connected to the dirt storage area 4, and a top cover is installed on the other end of the drain pipe, a second discharge hole 11 is opened inside the partition 8, and a mounting member 9 is fixedly installed inside the partition 8, the mounting member 9 is a hollow arched cylinder, and a first discharge hole 10 is opened at one end of the mounting member 9.

[0059] In this embodiment, a top cover is provided to seal the sewage pipe, and the internal space of the storage and drainage tank body can be divided by providing a partition 8 to form a dirt storage area 4. When the sewage enters the storage and drainage tank body, the dirt settles downward due to gravity and accumulates on the top of the partition 8. At this time, the dirt flows into the dirt storage area 4 through the first discharge hole 10 and the second discharge hole 11 inside the partition 8 for storage. By providing the second discharge hole 11 inside the mounting part 9, the dirt reflux can be effectively prevented. When processing, the dirt in the dirt storage area 4 can be discharged by simply opening the top cover.

[0060] The control method further comprises:

[0061] When the external ambient temperature is lower than a preset threshold, the temperature control device is activated to heat and protect the storage and drainage tank body 1 to prevent ice from damaging the equipment.

[0062] The control method further comprises:

[0063] The amount of condensed water discharged each time is recorded by the discharge metering device, and the working parameters of the drainage device are adjusted accordingly to ensure the quality of compressed air.

[0064] The control method further comprises:

[0065] An emergency exhaust switch is provided on the storage and drainage tank body 1. When sewage cannot enter the storage and drainage tank body 1, the emergency exhaust switch is manually opened to ensure smooth drainage.

[0070] Condensate discharge control device for compressed air, the device is suitable for the method described in any one of the above claims

[0071] It should be noted that a storage and drainage tank body 1 is set at the low point of the compressed air pipeline, and the tank body must be able to accommodate a certain amount of condensed water and have sufficient strength to withstand the pressure of the compressed air pipeline. The storage and drainage tank body 1 should be connected to the compressed air pipeline through the water inlet port 2 to facilitate the introduction of condensed water in the pipeline into the tank body.

[0072] A partition 8 is provided inside the storage and drainage tank 1, which divides the tank into two parts, one part is the condensed water storage area, and the other part is the dirt storage area 4. A certain gap is left between the bottom of the partition 8 and the inner wall of the tank to form the dirt storage area 4, so that the dirt and rust residue in the condensed water can be introduced into this area and regularly removed through the sewage port.

[0073] A water level monitoring system is installed in the storage and drainage tank 1, including but not limited to components such as a low water level sensing switch 5, a high water level sensing switch 6, and a water level sensor 7. When the condensed water in the tank reaches a preset water level, the water level monitoring system will trigger the drainage solenoid valve 3 to start drainage. When the water level drops to a preset low level, the water level monitoring system will close the drainage solenoid valve 3 to restore the normal operation of the compressed air pipeline.

[0074] Furthermore, in order to reduce noise during the drainage process and speed up the drainage, a buffer valve is installed at the water inlet port 2 of the water storage and drainage tank body 1. The buffer valve has a leakage hole that can supplement pressure to the water storage and drainage tank body 1 to maintain the pressure balance between the tank body and the pipeline.

[0075] In some embodiments, a temperature control device is installed on the water storage and drainage tank 1. When the external ambient temperature is lower than a preset threshold, the temperature control device automatically starts to heat the tank to protect it and avoid damage to the equipment caused by icing.

[0076] A discharge metering device is installed on the storage and drainage tank body 1, which can record the amount of condensed water discharged each time and adjust the working parameters of the drainage device according to these data to ensure that the compressed air quality meets the standards.

[0077] Furthermore, an emergency exhaust switch is provided on the storage and drainage tank body 1. When sewage cannot smoothly enter the storage and drainage tank body 1, the emergency exhaust switch can be manually opened to ensure a smooth drainage process.

[0078] Furthermore, an inspection port is provided on the storage and drainage tank body 1, which is convenient for operators to regularly check the situation inside the tank and remove accumulated dirt and rust to ensure the normal operation of the equipment.

[0079] The external protection storage and drainage tank is integrated with control function switches and display devices, which can monitor and control the entire drainage process in real time and display equipment status information.

[0080] In summary, the described method is suitable for condensate discharge control of all types of compressed air systems and can be widely used in industrial production, manufacturing and other occasions where compressed air is required.
