Gas inlet device meeting requirements of pneumatic conveying industry for conveying clean gas

Abstract

The invention relates to the technical field of Roots blower equipment, in particular to a gas inlet device meeting the requirement of the pneumatic conveying industry for conveying clean gas. The device comprises an outer cylinder body, an inner cylinder body, a top cover and a bottom plate, the top end of the outer cylinder is hermetically and fixedly connected with the top cover; the bottom end of the outer cylinder is hermetically and fixedly connected with the bottom plate; the inner cylinder is arranged in the outer cylinder, the top end of the inner cylinder abuts against the top cover, and the bottom end of the inner cylinder penetrates through a bottom plate of the outer cylinder to be communicated with the outside; a space defined by the outer cylinder body, the inner cylinder body, the top cover and the bottom plate is also filled with a filtering filler; an air inlet connecting pipe is connected to the cylinder wall of the outer cylinder in a penetrating manner; a plurality of through holes are formed in the inner cylinder body; the bottom end of the inner cylinder is connected with an air outlet connecting pipe. The gas inlet connecting pipe is horizontally and eccentrically arranged, so that entering gas can be sufficiently circulated in the filter element, and impurities can be effectively removed; low-temperature, clean and oil-free gas is obtained by taking gas from high altitude; and a negative pressure meter is arranged to judge whether the air inlet is blocked.

Description

technical field [0001] The invention relates to the technical field of Roots blower equipment, in particular to an air intake device that meets the requirements of the pneumatic conveying industry to convey clean gas. Background technique [0002] The pneumatic conveying industry requires the conveying of oil-free, clean and low-temperature gas. Generally, a Roots blower is used for gas transportation; at the same time, an air intake device is installed on the intake side of the Roots blower, which is filled with filter elements. In addition to the air intake device, a sound insulation cover must be installed to reduce noise. [0003] The traditional air intake device generally adopts one end closed, and the other end is inhaled and exhausted, and the air cannot circulate well in the air intake device; and the air around the working place of the blower is often oily and high in temperature, which leads to the filtering of the air intake device. The effect is often not very ...
