Description

TECHNICAL FIELD

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

[0002] Compressed air systems are widely used in industrial production and daily life, such as pneumatic tools, automation control, food processing, etc. However, due to the contact between compressed air and the pipe wall during transportation, condensate water is easily produced. The condensate water not only contains water, but also carries impurities, oil stains, rust products and other pollutants in the pipeline. If not timely discharged, these condensate 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 water discharge usually adopts manual or timed automatic discharge. Manual discharge is inefficient, while timed discharge may cause early or late discharge, resulting in resource waste or system pollution. In addition, a large noise may be produced during the discharge process, and in cold environments, the condensate water in the pipeline may freeze, causing equipment damage. SUMMARY

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

[0005] The present application provides a condensate water discharge control method for compressed air, which comprises:

[0006] A storage and discharge tank is arranged at a low point of the compressed air pipeline;

[0007] The condensate water in the pipeline is introduced into the storage and discharge tank through a water inlet port;

[0008] The dirt and rust residues in the condensate water are introduced into a dirt storage area;

[0009] When the condensate water in the storage and discharge tank reaches a preset water level, a water level monitoring system triggers a drain electromagnetic valve to discharge water;

[0010] After the discharge is completed, the drain electromagnetic valve is closed, so that the pressure in the storage and discharge tank is balanced with the pipeline pressure, and the normal operation of the compressed air pipeline is restored.

[0011] In one possible implementation, the control method further comprises:

[0012] During the discharge process, the pressure in the storage and discharge tank is supplemented through the flow relief hole on the buffer valve of the water inlet port, so as to reduce the noise during the discharge process and speed up the discharge speed.

[0013] In a possible implementation, the water level monitoring system is used to close the drain electromagnetic valve when the water level in the water storage and drainage tank drops to a preset low level.

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

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

[0016] A dirt separation structure is arranged in the water storage and drainage tank to collect the precipitated dirt and rust residues, and the dirt and rust residues are periodically removed through a dirt outlet.

[0017] The dirt separation structure comprises a partition plate and a dirt outlet pipe. The partition plate is fixedly installed on the inner wall of the water storage and drainage tank. A gap between the bottom of the partition plate and the inside of the water storage and drainage tank forms a dirt storage area. The dirt outlet pipe is fixedly installed inside the water storage and drainage tank. One end of the dirt outlet pipe is in communication with the dirt storage area, and the other end of the dirt outlet pipe is provided with a top cover. A second discharge hole is formed in the partition plate. An installation member is fixedly installed in the partition plate. The installation member is a hollow arc-shaped cylinder. A first discharge hole is formed in one end of the installation member.

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

[0019] When the temperature of the external environment is lower than a preset threshold, a temperature control device is started to heat the water storage and drainage tank to prevent freezing damage to the equipment.

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

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

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

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

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

[0025] An inspection port is arranged on the water storage and drainage tank to periodically inspect the inside of the tank and remove accumulated dirt and rust residues.

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

[0027] The control function switch and display device are arranged on the outer protection water storage and drainage tank body, used for monitoring and controlling the entire drainage process, and displaying the device state.

[0028] In a possible implementation, the condensate water drainage control device for compressed air is suitable for the method described in any of the above.

[0029] In the condensate water drainage control method and device for compressed air described above, by arranging the water level monitoring system, real-time monitoring of the condensate water level in the water storage and drainage tank body is realized, and when the water level reaches the preset value, the drainage electromagnetic valve is automatically triggered for drainage, thereby avoiding the inconvenience caused by manual operation and the inaccuracy of timed drainage. When the external temperature is lower than the preset threshold value, the temperature control device automatically starts the heating protection function to prevent the condensate water from freezing and causing damage to the equipment, thereby improving the reliability of the system. During the drainage process, the buffer valve on the water inlet port is supplemented with pressure through the drain hole, effectively reducing the noise generated during the drainage process, and improving the working environment.

[0030] The condensate water quantity of each drainage is recorded by the drainage 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 optimal state.

[0031] The inspection port and emergency exhaust switch are arranged on the water storage and drainage tank body, which facilitates regular inspection of the inside of the tank and removal of accumulated substances, and manual intervention in abnormal conditions, thereby ensuring long-term stable operation of the equipment.

[0032] The control function switch and display device on the outer protection water storage and drainage tank body enable the staff to check the device state at any time and make necessary operation adjustment, thereby enhancing the operability and transparency of the system.

The terms "first", "second", etc. in the specification and claims and the above-described drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0044] Based on this, the embodiments of the present application provide a condensate drain control method for compressed air, which aims to control condensate drain and reduce noise.

[0045] Please refer to Figures 1-6 , the present embodiment provides a technical solution: the method comprises:

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

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

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

[0049] When the condensate water in the storage and drainage tank body 1 reaches the preset water level, the water level monitoring system triggers the drainage electromagnetic valve 3 to drain water;

[0050] After the drainage is completed, the drainage electromagnetic valve 3 is closed, so that the pressure in the storage and drainage tank body 1 is balanced with the pipeline pressure, and the normal operation of the compressed air pipeline is restored.

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

[0052] During the drainage process, the pressure in the storage and drainage tank body 1 is supplemented through the drain hole on the buffer valve of the water inlet port 2, which is used to reduce the noise during the drainage process and speed up the drainage speed.

[0053] After the water level in the storage and drainage tank body 1 drops to the preset low level, the water level monitoring system closes the drainage electromagnetic valve 3;

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

[0055] The low water level sensing switch 5, the high water level sensing switch 6 and the water level sensor 7 can be used to sense and detect the water level inside the storage and drainage tank body.

[0056] The method further comprises:

[0057] A dirt separation structure is arranged in the storage and drainage tank body 1 to collect the deposited dirt and rust residues, and is regularly cleaned through the dirt discharge port;

[0058] The dirt separation structure comprises a partition plate 8 and a dirt discharge pipe. The partition plate 8 is fixedly installed on the inner wall of the storage and drainage tank body. The gap between the bottom of the partition plate 8 and the inside of the storage and drainage tank body forms a dirt storage area 4. The dirt discharge pipe is fixedly installed inside the storage and drainage tank body. One end of the dirt discharge pipe is in communication with the dirt storage area 4, and the other end of the dirt discharge pipe is provided with a top cover. A second discharge hole 11 is formed in the partition plate 8, and a mounting piece 9 is fixedly installed in the partition plate 8. The mounting piece 9 is a hollow arc-shaped cylinder, and a first discharge hole 10 is formed in one end of the mounting piece 9.

[0059] The top cover can block the drain pipe. The partition plate 8 is arranged to divide the internal space of the water storage and drainage tank into a dirt storage area 4. When the sewage enters the internal space of the water storage and drainage tank, the dirt will sink downward and accumulate on the top of the partition plate 8 due to gravity. At this time, the dirt flows into the dirt storage area 4 through the first and second discharge holes 10 and 11 in the partition plate 8 and is stored. The second discharge hole 11 is arranged in the mounting piece 9 to effectively prevent the backflow of the dirt. When the dirt in the dirt storage area 4 is to be discharged, the top cover is opened.

[0060] The control method further comprises:

[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 water drainage device are adjusted accordingly to ensure the quality of compressed air.

[0064] The control method further comprises:

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

[0067] An inspection port is arranged on the water storage and drainage tank 1 to periodically inspect the inside of the tank and remove accumulated dirt and rust.

[0072] A partition 8 is provided in the drain tank 1, which divides the tank into two parts, one part is the condensate 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, forming the dirt storage area 4, so that the dirt and rust in the condensate can be introduced into this area and periodically removed through the drain port.

[0073] A water level monitoring system is installed in the drain tank 1, including but not limited to low water level sensing switch 5, high water level sensing switch 6, and water level sensor 7, etc. When the condensate in the tank reaches the preset water level, the water level monitoring system will trigger the drain electromagnetic valve 3 to start draining. When the water level drops to the preset low level, the water level monitoring system will close the drain electromagnetic valve 3 to restore the normal operation of the compressed air pipeline.

[0074] Further, in order to reduce the noise during the drainage process and speed up the drainage speed, a buffer valve is installed at the water inlet port 2 of the drain tank 1, which has a drain hole to supplement the pressure to the drain tank 1 to maintain the pressure balance between the tank and the pipeline.

[0075] In some embodiments, a temperature control device is installed on the drain tank 1. When the external environment temperature is lower than the preset threshold, the temperature control device automatically starts to heat the tank to prevent freezing and damage to the equipment.

[0076] A discharge metering device is installed on the drain tank 1, which can record the amount of condensate 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 standard.

[0077] Further, an emergency exhaust switch is provided on the drain tank 1, which can be manually opened when the sewage cannot enter the drain tank 1 smoothly to ensure the smoothness of the drainage process.

[0078] Further, an inspection port is provided on the drain tank 1 to facilitate the operator to regularly inspect the condition in the tank and remove the accumulated dirt and rust to ensure the normal operation of the equipment.
