Oil-free vortex air pump special for melt-blown cloth

Abstract

The invention relates to the technical field of air pumps, and discloses an oil-free vortex air pump special for melt-blown cloth. The air pump comprises a pump head, a cooling tank and a dust filtering box, wherein a connecting hole is formed in the middle of one side of the pump head, an air inlet is formed in one side of the bottom end of the pump head, an air inlet pipe is fixedly connected tothe outer side of the air inlet, and metal rods are fixedly connected to the two ends of the right side of the dust filtering box. According to the oil-free vortex air pump special for the melt-blowncloth, through the arrangement of a rotating rod, the rotation of the rotating rod can drive an air volume adjusting plate, fixedly connected with the rotating rod, to rotate, the air inlet volume inan inner cavity of the air inlet pipe can be changed through the rotation of the air volume adjusting plate, and the practicability of the air pump is improved; and the rotating rod drives a pointer,fixedly connected with the rotating rod, to rotate in the rotating process, the pointer and an annular scale are used in cooperation, a user can accurately adjust the deflection direction of the airvolume adjusting plate, in other words, the user can accurately control the air inlet volume, and the air pump is convenient to use.

Description

technical field [0001] The invention relates to the technical field of air pumps, in particular to an oil-free vortex air pump for melt blown cloth. Background technique [0002] The air pump is an "air pump", a device that removes air from a closed space or adds air from a closed space. The electric scroll air pump is an air pump powered by electricity. It is accelerated along the blade and the radial direction, and after the gas enters the outer gas ring, it uses the pressure difference to return to the base of the blade to form a strong air flow, so that the gas moves in a spiral direction in the gas ring to achieve the purpose of pressurization. Oil-free air pump means that there is no lubricating oil between the piston and the cylinder of the air pump. The piston ring is made of special materials such as silicon carbide. It is generally used to pump clean special gases, such as liquefied petroleum gas, natural gas, etc. [0003] The oil-free scroll air pump for meltblo...
