Technical Field

[0002] Compressors are the basic products of industrial modernization. The commonly mentioned electrical and automation have the meaning of full pneumatics, and air compressors provide air source power. They are the core equipment of pneumatic systems and the main body of electromechanical air source devices. They are devices that convert the mechanical energy of the motive force into gas pressure energy and are compressed air pressure generating devices. Lubricating oil is a chemical product that is harmful to the human body and has an impact on processes such as textile dyes. Therefore, in some textile industries, especially food and medical industries, the oil content of compressed air is very high. In the application process of air compressors, many process systems have long been troubled by lubricating oil in compressed air. In the case of unsatisfactory oil-gas separation technology, this drawback has even slowed down the speed of technological progress to some extent, causing many process flows to stagnate for a long time. With the continuous advancement of science and technology, the innovation of manufacturing processes, and the improvement of product quality levels, the process flow that requires compressed gas to be oil-free is becoming more and more common. This undoubtedly makes the market prospects of oil-free air compressors broader. In a sense, this is the development direction of air compressors. In the wave of research and development of oil-free models, water-lubricated oil-free compressors will undoubtedly become the mainstream of the market. Water-lubricated oil-free compressors produce a lot of humid air during use, so a water-gas separation barrel is needed. Currently, the water-gas separation barrels of traditional water-lubricated oil-free compressors on the market are mostly complex in structure, resulting in high manufacturing costs, and some water-gas separation barrels have poor separation effects. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides a water-gas separation barrel of a water-lubricated oil-free screw compressor, comprising: a separation barrel body, an air inlet is provided on one side surface of the separation barrel body; a head is provided at the top and bottom ends of the separation barrel body, the head at the top end is provided with an exhaust port, and the head at the bottom end is provided with a drain port;

[0005] The separation barrel body is provided with a separation barrel inner barrel and a return pipe; the bottom of the separation barrel inner barrel is a porous plate, and the separation barrel body wall is provided with an oil mirror mounting port, a water filling port, a pressure gauge mounting port, a water inlet, a safety relief device and two pressure transmitter mounting ports, the two pressure transmitter mounting ports are connected to each other and to the pressure transmitter; the water inlet is arranged above the drain port, and the water inlet and the drain port are respectively connected to a solenoid valve; the bottom end surface of the separation barrel body is provided with fixed feet.

[0006] Compared with the prior art, the technical solution of the utility model has the following beneficial effects:

[0007] The utility model discloses a water-gas separation barrel of a water-lubricated oil-free screw compressor. When in use, the mixed water and gas enter the separation barrel through the air inlet, hit the inner barrel of the separation barrel, and realize water-gas separation. The separated gas gathers at the top of the separation barrel, and the liquid gathers at the bottom of the barrel. When a certain pressure is reached, the water at the bottom of the barrel is pressed out of the separation barrel through the return pipe, and the pressure-maintaining valve installed at the exhaust port opens to discharge the gas. And it has a structure for connecting a pressure transmitter to indirectly monitor the liquid level, so as to achieve the effect of automatically replenishing the liquid level / lowering the liquid level. Compared with the existing traditional water-lubricated oil-free compressor water-gas separation barrel structure on the market, the water-gas separation barrel disclosed by the utility model has a simple structure, is easy to assemble, has a lower manufacturing cost, and has a higher degree of automation.
