Description

Technical Field

[0001] The utility model relates to the field of gas tanks for storing compressed air, in particular to a compressed air tank. Background Art

[0002] Compressed air is mechanically compressed air. Equipment used to produce compressed air is often called an air compressor. Humans have long understood the use of compressed air, and it has become an indispensable power source for production and daily life. With the continuous development of modern industry, the requirements for compressed air quality are becoming increasingly higher and more diverse.

[0003] Because air contains water, known as humidity, it becomes supersaturated after compression, and the water in the air is extracted, forming a liquid. This is because the internal temperature of the air compressor head is very high when it is operating. The moisture in the natural air drawn in will form water vapor during the operation of the air compressor. The air tank not only provides a buffer and storage space for the compressed air, but also reduces pressure and temperature. When the compressed air passes through the air tank, the high-speed airflow hits the tank wall, causing it to converge. This rapidly drops the temperature inside the tank, causing a large amount of water vapor to liquefy and form condensate. In humid weather or winter, even more condensate forms. The moisture content of compressed air is related to the humidity of the air. If the environment is too humid, the water content in the air will exceed the usage standard. Currently, compressed air used in industrial production is first stored in compressed air tanks and then transported when needed. This mainly leads to the following problems:

[0004] 1. Before receiving compressed air from the air compressor and storing it, the compressed air tank usually passes through a dryer to dry and filter out moisture. However, in actual use, the filtering effect is far from ideal, and there will still be water in the compressed air tank;

[0005] 2. In addition to water, compressed air also contains oil stains, tiny dust and particulate garbage. The current compressed air tanks are equipped with a drain valve at the bottom for drainage, but cannot discharge the oil stains, dust and particulate garbage in the air. Utility Model Content

[0006] The purpose of the utility model is to at least solve the problem that water exists in the existing compressed air tank.

[0007] In order to solve the above technical problems, the utility model of the compressed air tank includes:

[0008] A tank body, wherein the bottom of the tank body has at least three fixedly connected supporting legs; the side of the tank body has an air outlet pipe fixedly connected;

[0009] The overflow pipe is at a vertical angle; the upper end of the overflow pipe is connected to the tank; the overflow pipe is provided with a first valve,

[0010] Intake pipe;

[0012] A sealing tube is detachably connected to the overflow main pipe; the connection position of the sealing tube is lower than the first valve but higher than the connection position of the air intake main pipe and the overflow main pipe; a detachably connected filter element is provided in the sealing tube.

[0013] As a preferred embodiment of the compressed air tank of the present invention, a pressure relief valve is provided on the side of the tank body, and a pressure gauge is installed on the pressure relief valve.

[0014] As a preferred embodiment of the compressed air tank of the utility model, it includes a recoil pipe, one end of which is connected to the air inlet pipe, and the other end of the recoil pipe is connected to the flow main pipe, and the connection position between the recoil pipe and the flow main pipe is between the sealing pipe and the first valve; the recoil pipe is provided with a third valve.

[0015] As a preferred embodiment of the compressed air tank of the present invention, the flow main pipe has two sections, and the two adjacent sections respectively have fixedly connected flanges; the upper and lower ends of the sealing pipe are fixedly connected to the flanges.

[0016] As a preferred embodiment of the compressed air tank of the present invention, the sealing tube is connected to the flange by bolts.

[0017] As a preferred embodiment of the compressed air tank of the utility model, an automatic drain pipe is connected below the overflow main pipe, and the automatic drain pipe is installed with an automatic steam trap;

[0018] The automatic drain pipe is installed with a fourth valve, and the fourth valve is located between the automatic steam trap and the overflow main pipe.

[0020] Beneficial effects

[0021] The present invention solves the above existing problems and other existing problems not mentioned above and accordingly brings at least the following innovative advantages:

[0022] The utility model of compressed air tank connects the air intake pipe, the air intake main pipe and the flow main pipe, so that the compressed air entering the air intake pipe can enter the tank body through the flow main pipe. In the process of air entering the tank body, it will first pass through the filter element in the sealed pipe, so that the filter element can filter the water and oil in the air, thereby reducing the water content in the compressed air. At the same time, every once in a while,

[0023] The utility model discloses a compressed air tank, which can be conveniently inspected and replaced with a new filter element by installing the filter element in a sealed tube.

[0024] The utility model compressed air tank has an additional backflush pipe. When there is a lot of oil stains, dust and particulate matter on the surface of the filter, the first valve and the second valve can be closed, allowing the air entering the intake pipe to enter the flow main pipe through the backflush pipe, causing the air to flow in the reverse direction in the flow main pipe, blowing away the oil stains, dust and particulate matter on the surface of the filter and discharging them to the outside, thus solving the problem of the oil stains, dust and particulate matter stored in the compressed air tank being unable to be discharged. Another solution is to close the second valve and the third valve at the same time, using the compressed air in the tank body to blow away the oil stains, dust and particulate matter on the surface of the filter.
