Description

Anti-clogging and power-free automatic drain

This creation is about the compressed air supply system, especially the drainer of the air tank that stores high-pressure air.

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

In the conventional technology, an automatic drain is installed at the bottom of the gas storage barrel. The automatic drain will automatically drain at regular intervals or if the accumulated water exceeds a certain amount, which can reduce the burden of manpower draining.

Conventional automatic drains use power-controlled electronic valves to discharge stagnant water. They can be drained at a fixed time using an electronic timer, or use capacitance changes to detect the level of stagnant water to control the discharge time. However, this type of auto drain, Often due to impurity clogging, failures or drainage failures are caused, causing great distress to users. Among them, the method of discharging the accumulated water at a fixed time is prone to excessive discharge and waste of energy in the exhaust gas, and even causes an obvious instantaneous pressure drop in the gas storage tank. However, the method of using capacitance change to detect the water level of the stagnant water has the problem of impurity accumulation and wrong detection, which may cause excessive discharge or abnormal discharge.

In the past, some users would try to install a Y-type filter before the automatic drain to intercept and filter impurities. However, the built-in filter of the Y-type filter has a small dust holding capacity, which often blocks the flow and causes water to accumulate. The automatic drain is completely inaccessible, so users need to use tools to disassemble the Y-type filter and take out the built-in filter for cleaning. This is time-consuming and labor-intensive and troublesome, and if the built-in filter is not cleaned in time, it will cause The drainage system fails, and the water diffuses downstream, which seriously affects the production line.

As mentioned above, the conventional automatic drainer must overcome the impurity clogging problem before it can be used normally. Not only can it not meet the user's convenience needs, it consumes manpower and time, and it may also have the problem of not being able to automatically drain due to damage to the power system.

The main purpose of this creation is to expose an anti-clogging and power-free automatic drain, which can automatically clean and drain without power supply, and solve the problem that the automatic drain often fails due to impurity blockage.

Based on the above-mentioned purpose, this creation is an anti-clogging and power-free automatic drain, which is used to discharge a water and an impurity in a gas storage barrel. It includes a pneumatic drain valve, a water inlet pipe, a water reservoir, and a float Ball water valve and a floating ball air valve, wherein the pneumatic sewage valve has a pneumatic valve and a normally closed sewage pipe, the pneumatic valve has an air inlet end, and when the air inlet end is given an air inlet Under pressure, the pneumatic valve will act to open the drain pipe. One end of the water inlet pipe is connected with the air storage barrel to receive the accumulated water and the impurities, and the other end is connected with the pneumatic drain valve. When the drain pipe is opened, the accumulated water will entrain the impurities and be discharged. The water accumulation cavity is connected to the water inlet pipe and is located above the water inlet pipe. The float water valve is located in the water accumulation cavity, and the float water valve has a first float and a constant that is linked by the first float. The closed water valve opens the normally closed water valve when the first floating ball floats due to the accumulated water, so that the normally closed water valve can discharge the accumulated water. The float air valve is located in the water accumulation cavity, and the installation height of the float air valve is higher than the installation height of the float water valve. The float air valve has a second float and a second float. A normally closed air valve linked by a ball, the normally closed air valve communicates with the intake end. When the second floating ball floats due to the accumulation of water, the normally closed air valve is opened, and the air pressure in the water accumulation cavity is applied to the intake end. Give the intake pressure.

According to this, when the height of the stagnant water exceeds the floating ball valve, buoyancy is used to open the floating ball valve to discharge the stagnant water, and when the impurities accumulate, the stagnant water cannot be discharged, and the height of the stagnant water is sufficient When the float valve is activated, the float valve will exhaust and generate the intake pressure. The intake pressure will open the pneumatic drain valve. After the pneumatic drain valve is opened, the accumulated water can be discharged, and The impurity will be entrained and discharged together, and its mechanism is an automatic operation combining buoyancy and air pressure actuation, and does not need to use electricity, so it provides users with excellent convenience in application.

Regarding the detailed content and technical description of this creation, examples are now used for further description, but it should be understood that these examples are for illustrative purposes only, and should not be interpreted as restrictions on the implementation of the creation.

Please refer to "Figure 1", "Figure 2" and "Figure 3". This creation is an anti-clogging and power-free automatic drain for discharging a pool of water 11 and an impurity 12 in an air tank 10. It includes a pneumatic drain valve 20, a water inlet pipe 30, a water chamber 40, a floating ball water valve 50 and a floating ball air valve 60. The pneumatic drain valve 20 has a pneumatic valve 21 and a normally closed valve. In the sewage pipe 22, the pneumatic valve 21 has an intake end 211, and when the intake end 211 is applied with an intake pressure, the internal valve member (not shown) of the pneumatic valve 21 will act to open the Sewage pipe 22.

One end of the water inlet pipe 30 is connected to the air tank 10 to receive the accumulated water 11 and the impurities 12, and the other end is connected to the pneumatic drain valve 20. The pneumatic drain valve 20 is mainly used to discharge the impurities 12, when the pneumatic drain When the sewage valve 20 is opened, the impurities 12 can be discharged from the sewage pipe 22 along with the accumulated water 11.

Please also refer to "FIG. 4". The float valve 50 is located in the water accumulation cavity 40, and the float valve 50 has a first float 51 and a first float 51 that is linked by the first float 51. When the first floating ball 51 floats due to the accumulated water 11, the normally closed water valve 52 can be opened, and the normally closed water valve 52 can discharge the accumulated water 11 to a drain pipe 53 , So that the water level in the water accumulation cavity 40 drops.

The water accumulation cavity 40 is connected to the water inlet pipe 30 and is located above the water inlet pipe 30. A tubular filter 31 for filtering the impurities 12 may be provided between the water inlet pipe 30 and the water accumulation cavity 40. The filter screen 31 can intercept and filter most of the impurities 12 therein, reducing the possibility of the impurities 12 entering the water accumulation cavity 40, thereby reducing the risk of clogging of impurities, so that the floating ball valve 50 can maintain normal operation.

In order to allow the accumulated water 11 to enter the water accumulation cavity 40 smoothly, a pressure equalization pipe 41 may be connected between the water accumulation cavity 40 and the air storage barrel 10, and the pressure equalization pipe 41 allows the air in the water accumulation cavity 40 to be connected. The pressure is equal to the gas pressure in the gas storage tank 10, so the water in the gas storage tank 10 can flow into the water storage cavity 40 by the principle of gravity and a fluid communication tube. On the contrary, if the pressure equalizing tube is not provided, the air in the water accumulation cavity 40 will be compressed, causing an air lock phenomenon, which hinders the water inflow, and the accumulated water in the air storage barrel 10 cannot enter the water accumulation cavity 40 smoothly.

In one embodiment, the water-storing cavity 40 includes an upper shell 42 and a lower shell 43 in a butt-joint combination. And the upper shell 42 and the lower shell 43 are fixed by a plurality of bolts 44. In addition, a rubber ring 45 may be provided at the junction of the upper shell 42 and the lower shell 43 to increase the sealing effect and avoid fluid leakage. The float air valve 60 is located in the water accumulation cavity 40, and the installation height of the float air valve 60 is higher than the installation height of the float water valve 50. The float air valve 60 has a second float 61 and A normally closed air valve 62 linked by the second float 61, the normally closed air valve 62 can communicate with the air inlet 211 through a vent pipe 63.

In the process of operation, because the impurities 12 are continuously filtered in the tubular filter 31, they will eventually accumulate too much and block the water inlet pipe 30, resulting in the stagnant water 11 being unable to enter the water collecting cavity 40, so the water inlet pipe 30. One end close to the air storage tank 10 may have a bypass pipe 32 communicating with the water accumulation cavity 40. When impurities in the tubular filter 31 are blocked and cannot enter water, the accumulated water 11 will entrain part of the impurities 12 The bypass pipe 32 enters the water accumulation cavity 40. In this case, the accumulated water 11 can continue to be discharged from the drain pipe 53.

Please also refer to "Figure 5". When the impurities 32 entering the water accumulation cavity 40 through the bypass pipe 32 gradually accumulate for a period of time, the float valve 50 will be blocked and jammed, and the normally closed The water valve 52 cannot drain water normally. At this time, the water level in the water accumulation cavity 40 cannot drop, but continues to rise. When the second floating ball 61 floats due to the rising water level, the normally closed air valve 62 is opened, and the air pressure in the water accumulation cavity 40 applies the air inlet pressure to the air inlet 211, and at the same time, the pneumatic The valve 21 is actuated to open the sewage pipe 22 so that the impurities 12 accumulated in the tubular filter 31 are discharged from the sewage pipe 22 along with the accumulated water 11.

In addition, when the second floating ball 61 floats due to the rising of the water level, and the pneumatic valve 21 is activated to open the sewage pipe 22, due to the fluid pressure difference between the inside of the water chamber 40 and the outside of the pipe, it will suddenly A pulsed downwash flow is formed in the water accumulation cavity 40, and this pulsed downwash flow can scour the impurities clogged in the water accumulation cavity 40 down and away, so that the float valve 50 instantly restores its normal drainage function , The stagnant water 11 can continue to be drained from the drain pipe 53, and the water level drops. The impurities carried away by the downward scouring will gradually settle and accumulate in the lower half of the inlet pipe 30. The user only needs to check at intervals and open a manual drain valve under the inlet pipe 30. 81, this impurity can be discharged. When the user opens the manual drain valve 81, due to the same fluid pressure difference, a pulsed downwash is instantly formed in the water accumulation cavity 40, which also helps to quickly remove the impurities accumulated by sedimentation.

In one embodiment, the normally closed air valve 62 is further connected to an air whistle 70. When the normally closed air valve 62 is opened due to the rising water level, the air whistle 70 will be activated and a whistle alarm will sound. When the water level still cannot drop, the normally closed air valve 62 will continue to be in the open state. At this time, the air whistle 70 will continue to sound an alarm. After hearing the alarm, the user can open the manual drain valve 81 to perform The dirt is cleaned, and the clogged impurities in the water accumulation cavity 40 are immediately removed, so that the floating ball water valve 50 returns to the normal drainage function and continues to drain.

In addition, the air inlet 211 can be connected to a manual air valve 80. The manual air valve 80 is mainly used to allow the user to manually remove the impurities 12 in the tubular filter 31 at any time, so as to delay the tubular filter. Impurities within 31 are blocked. The manual air valve 80 is connected to the air storage barrel 10 via the pressure equalizing pipe 41, so as long as the manual air valve 80 is manually opened, the air storage barrel 10 will supply air pressure and apply the air inlet pressure to the air inlet 211 , The pneumatic valve 21 is driven to open the sewage pipe 22 to discharge impurities.

In terms of operation and use, the user can open the manual air valve 80 and the manual drain valve 81 at any time to check the amount of impurities discharged to understand whether the tubular filter 31 and the water accumulation chamber 40 have accumulated too much Impurities, while expelling impurities and avoiding clogging.

As mentioned above, the present invention includes at least the following advantages.

1. Drain the stagnant water through the floating ball valve, and when the impurities accumulate so that the stagnant water cannot be discharged, use the floating ball valve to exhaust the air and open the pneumatic drain valve for draining, so that the stagnant water entrains the water.

2. Through the setting of the air whistle, to warn that the normally closed air valve has been opened, so that the user can grasp the status of sewage and the operation of the drain.

3. It has a manual drain design, which can actively drain to increase the reliability and service life of the automatic drain filter element.

4. When cleaning the pollution, it can be operated on-line without interrupting the current and stopping the machine, so as to avoid disturbing the operation of the production line.

5. With the design of the equalizing pipe, the equalizing pipe can balance the internal pressure of the water accumulation cavity and the air storage barrel, so that the accumulated water can smoothly enter the water accumulation cavity.
