[0028] The technical solution of the utility model proposes a workshop compressed air condensate discharge device.

[0029] Reference Figure 1 to Figure 2 , in this embodiment, includes:

[0030] The collecting tank 1 has a water inlet pipe 11 and an air vent pipe 12 fixedly connected to the upper end. The water inlet pipe 11 is connected to the compressed air pipe, and the air vent pipe 12 is connected to the air vent port. A drain pipe 13 is provided at the bottom of the collecting tank 1. The water inlet pipe 11 is provided with a water inlet pipe electric valve 111, the air vent pipe 12 is provided with an air vent pipe electric valve 121, and the drain pipe 13 is provided with a drain pipe electric valve 131.

[0031] A wastewater collection port 2, a drain pipe 13 is connected to the wastewater collection port 2, and the wastewater collection port 2 is used to collect condensed water;

[0032] A capacitive liquid level meter 3 is at least partially disposed in the collection tank 1, and the capacitive liquid level meter 3 is used to detect the condensed water level in the collection tank 1;

[0033] The control device, the water inlet pipe electric valve 111, the vent pipe electric valve 121, the drain pipe electric valve 131 and the capacitive liquid level meter 3 are all electrically connected to the control device.

[0034] Optionally, in this embodiment, a water inlet pipe 11 and an air vent pipe 12 are fixedly provided at the upper end of the collection tank 1, wherein the water inlet pipe 11 is connected to the compressed air pipe, the compressed air pipe is used to receive compressed air from the workshop, and condense into water and enter the collection tank 1 through the water inlet pipe 11, the air vent pipe 12 is connected to the air vent port to discharge the high-pressure gas in the collection tank 1; the drain pipe 13 is used to discharge condensed water; the wastewater collection port 2 is connected to the drain pipe 13 to receive the wastewater flowing out of the drain pipe 13 to prevent the wastewater from causing The capacitive level gauge 3 is at least partially arranged in the collection tank 1, and can detect the condensate water level in the collection tank 1 to prevent the water level from being too high, and timely remind and discharge, wherein the water inlet pipe electric valve 111, the vent pipe electric valve 121, the drain pipe electric valve 131 and the capacitive level gauge 3 are all electrically connected to the control device, that is, the detection result of the capacitive level gauge 3 can be fed back to the control device, if the condensate water level exceeds the height set in the program, the control device controls the drain pipe electric valve 131 and the water inlet pipe electric valve 121 to discharge the condensate water. The electric valve 111 is closed, and the water intake is stopped. At the same time, the vent pipe electric valve 121 is started to discharge the high-pressure gas in the collection tank 1 from the vent port through the vent pipe 12. Then the vent pipe electric valve 121 is closed, and the drain pipe electric valve 131 is opened to discharge the condensate. The water level of the capacitive liquid level gauge 3 is monitored to prevent the condensate from accumulating too high and generating a high static pressure, which leads to loud noise and strong impact during drainage. The vent pipe 12 is opened first to release the pressure in the collection tank 1 and discharge the high-pressure gas, further reducing the gas pressure in the collection tank 1, preventing the condensate from being discharged due to excessive pressure, causing excessive water velocity and loud noise, and avoiding water droplets from causing workshop environmental pollution. When the condensate is discharged to a certain extent, the drain pipe electric valve 131 and the vent pipe electric valve 121 are closed, and the water inlet pipe electric valve 111 is opened to continue accumulating the condensate until the detection result of the capacitive liquid level gauge 3 reaches the discharge standard. Through the arrangement of the above-mentioned device, the automatic discharge of the workshop condensate is realized, and the static pressure and noise during drainage are reduced.

[0035] In this embodiment, the workshop compressed air condensate discharge device also includes a water inlet pipe manual valve 112, a vent pipe manual valve 122 and a drain pipe manual valve 132. The water inlet pipe manual valve 112 is arranged on the water inlet pipe 11, the vent pipe manual valve 122 is arranged on the vent pipe 12, and the drain pipe manual valve 132 is arranged on the drain pipe 13; the manual valve is arranged as a backup or emergency control means for the electric valve, so that when the electric valve cannot work normally due to power failure, control system problems, etc., emergency operation can be performed through the manual valve to ensure the normal operation of the pipeline. At the same time, the existence of the manual valve also increases the flexibility of the system, and manual or automatic operation can be selected according to actual needs. In other embodiments, the workshop compressed air condensate discharge device can also be only provided with an electric valve or a manual valve, which is not limited here.

[0036] In this embodiment, the capacitive liquid level gauge 3 includes a connector 31, an inner electrode 33 and an outer electrode 32, wherein the connector 31 is used to be electrically connected to the control device, and the inner electrode 33 and the outer electrode 32 are used to detect the condensate water level, and the outer electrode 32 is provided with a first liquid level line 321, a second liquid level line 322, a third liquid level line 323 and a fourth liquid level line 324; the manual valve is usually in an open state, and when the condensate water is collected, the water inlet pipe electric valve 111 is opened, the drain pipe electric valve 131 and the vent valve electric pipe are closed, and the water level in the collection tank 1 is between the second liquid level line 322 and the third liquid level line 323; the first liquid level line 321 is a low water level alarm line, that is, when the condensate water level is at or below the first liquid level line 321, the control device sends a low water level alarm to remind the staff that the water level is too low and the pipeline is abnormal; The second liquid level line 322 is the water collection level line, and the third liquid level line 323 is the water discharge level line. When the water level exceeds the third liquid level line 323, the control device controls the water inlet pipe electric valve 111 to close first according to the set program, opens the vent pipe electric valve 121 to discharge the high-pressure gas, and finally opens the drain pipe electric valve 131 to drain the water; when the liquid level in the collection tank 1 drops to the second liquid level, the control device controls the drain pipe electric valve 131 to close first, and then closes the vent pipe electric valve 121, and finally opens the water inlet pipe electric valve 111 to collect condensate water, and repeats the above process. Through the venting of the vent pipe 12, the pressure in the collection tank 1 is released to the outside, so that the condensate flows to the wastewater collection port 2 by its own gravity, reducing the drainage power, reducing the flow rate of the condensate water, avoiding the impact on the external environment, and reducing the drainage noise. The fourth liquid level line 324 is a high water level alarm line. When the condensate water level reaches the first liquid level line 321 or the fourth liquid level line 324, the control device will sound an alarm to remind the staff that the water level in the collection tank 1 is abnormal and to perform timely maintenance.

Stainless steel has good corrosion resistance and heat resistance, which can prevent condensed water from corroding it. Setting the material of the above devices to stainless steel is conducive to electrochemical corrosion and increases the service life of the discharge device.

[0040] In this embodiment, a filtering device is provided between the water inlet pipe 11 and the compressed air pipe. The filtering device is provided to filter the compressed air to prevent impurities or harmful gases from entering the collection tank 1 and to discharge the compressed air through the drain port or the vent port.
