Inlet silencing filter of roots blower

Abstract

The invention provides an inlet silencing filter of a Roots blower, and relates to the technical field of silencing filtering equipment. The inlet silencing filter of the Roots blower comprises a main body, reserved openings are formed in the upper surface and the lower surface of the main body, fixing plates are arranged in the reserved openings, placing grooves are formed in the inner side surfaces of the reserved openings, locking mechanisms are arranged in the placing grooves, and each locking mechanism comprises a limiting block, a spring and a limiting groove. The springs are fixedly connected to the bottoms of the containing grooves, the bottoms, away from the containing grooves, of the springs are fixedly connected with the limiting blocks, the limiting grooves are formed in the left side surface and the right side surface of the fixing plate, and the positions of the limiting grooves correspond to the positions of the limiting blocks. And by using the locking mechanism, the fixing plate can be effectively locked and positioned, so that the fixing plate can be conveniently disassembled, the electrostatic dust collector and the air filter element in the fixing plate can be cleaned, and the stability of the filtering effect can be ensured.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing filtering equipment, in particular to an inlet sound-absorbing filter of a Roots blower. Background technique [0002] Roots-type blower is a positive displacement blower. It relies on the change of the volume of the working chamber formed by the rotation of two involute "8"-shaped rotors to transport gas. Its working principle is the same as that of a gear pump. That is, each rotor is equivalent to a gear with only two teeth, and the Roots blower is a volumetric rotary blower. This compressor maintains the meshing of the two rotors by means of a synchronous gear at the end of the rotor shaft. Each concave curved part on the rotor and the inner wall of the cylinder form a working volume. During the rotation of the rotor, the gas is taken away from the suction port. The gas is backflowed, when the pressure in the working volume suddenly rises, and the gas is then transported to the exhaus...
