Description

High-pressure self-equalizing type automatic drainer without air consumption

The present work is concerned with compressed air supply systems, especially with regard to the automatic drains of the condensate drain lines that store high-pressure compressed air installations.

Compressed air is a very important power source in the manufacturing industry. In addition to driving pneumatic tools and machines, it can also be used for dust removal, drying, bottle blowing, pressure setting, etc., and has a wide range of applications. Traditionally, compressed air can be generated by using an air pump to pressurize air. However, unfiltered compressed air will contain moisture, oil, and impurities. During the compression process, moisture, oil, and impurities cannot be removed. Therefore, when the compressed air is stored in the air pressure device for use, there will be accumulated water with impurities. The user must drain and clean it regularly to avoid contaminating the production line.

In the prior art, an automatic drainer is installed at the bottom of the air pressure device (eg, a gas storage tank), and the automatic drainer automatically drains the water every time period or when the accumulated water exceeds a certain amount, which can reduce the burden of manual drainage.

The conventional automatic drainer uses electronic control to discharge the stagnant water, which can be discharged at a fixed time, or use the capacitance change to detect the level of the stagnant water to control the discharge time. Among them, the method of discharging accumulated water at a fixed time is prone to excessive discharge, which leads to the phenomenon of exhaust pressure loss and waste, which will cause obvious pressure drop problems in the gas pipeline system. The method of detecting the water level of stagnant water by using the change of capacitance has the problem of accumulation of impurities and the problem of faulty detection. On the contrary, it causes excessive discharge or abnormal discharge, and even continuous discharge of compressed air leads to waste of energy.

On the other hand, in order to avoid problems such as improper installation structure and pipeline configuration, the conventional automatic drainer needs to be installed with an equalizing pipe in order to avoid the phenomenon that the air is blocked and the water cannot enter. It is connected to the source air pressure device that discharges the condensed water, so that the liquid water can smoothly enter the drain. This method will increase the installation process and manpower in the installation and application of the high-pressure automatic drain.

Yes, the main purpose of this creation is to disclose a high-pressure self-equalizing pressure-free automatic drainer without air consumption, which can automatically filter, clean and drain, without time and labor, and solve the problem that the automatic drainer is prone to air blockage failure and blockage failure. .

Based on the above purpose, the present invention discloses a high-pressure self-equalizing type automatic drain without air consumption, which is used for connecting a condensate water discharge pipeline of an air-compression system to discharge a stagnant water with an impurity entrained in it, which includes a pressure barrel, a self-equalizing pressure pipe, an inlet pipeline, an impurity filter pipe, two floating ball valves, two drainage columns, a branch pipe, a main sewage valve and a sewage pipe, wherein the two drainage columns are arranged on a bottom surface of the pressure barrel, And the two drainage columns respectively have a drainage channel, the inlets of the two drainage channels and the bottom surface are respectively separated by a height, the two floating ball valves are respectively arranged on the drainage column and have the ability to open the drainage according to the water level in the pressure bucket. A floating state of the flow channel and a sinking state closing the drainage channel, and the two ends of the branch pipe are respectively connected to the impurity filter tube and the pressure bucket, so that the pressure bucket can receive the stagnant water containing only traces of fine impurities, And the stagnant water is temporarily stored in the pressure barrel and often floods the inlet of the drainage channel, the sewage pipe is connected to a sewage outlet on the bottom surface of the pressure barrel, and the sewage pipe has a sewage valve for the first time. The blowdown valve can be opened to discharge the small amount of fine impurities deposited at the bottom of the pressure barrel, and the main blowdown valve is connected to the impurity filter pipe for discharging the impurities intercepted in the impurity filter pipe.

Accordingly, the automatic drainer disclosed in the present invention is designed to avoid power supply and ensure no blockage through the design of the two drainage channels and the two floating ball valves. The stagnant water often floods the inlet of the drainage channel and is designed for no air consumption, and the pressure barrel can withstand high pressure, which can meet the needs of high-pressure applications.
