AI Technical Summary

Technical Problem

When the air pressure drops after use, some of the grinding aid may flow back to the inner wall and accumulate, causing blockage and affecting the continuous and stable use of the device.

Method used

The cement grinding aid atomizing device adopts a coaxial double-shell structure. A dynamic sealing structure is formed by the sliding cooperation between the sealing piston and the sealing seat. The sealing piston is pushed by a spring to block the passage when there is no air pressure and to open the passage when the air pressure exceeds the pre-tightening force. The sealing piston is located on the side wall of the inner wall of the sealing piston. The sliding cooperation between the sealing piston and the sealing seat forms a dynamic sealing structure to prevent leakage. The passage is automatically controlled to open under the drive of air pressure.

Benefits of technology

Automatic control was implemented to prevent leakage during changes in air pressure, ensuring the sealing and effective sealing of the device, as well as its stability and sealing effect. Automatic control of the grinding aid pathway ensured the continuous and stable use of the device.

Abstract

The utility model relates to the technical field of cement processing, and discloses a cement grinding aid atomizing device which comprises a connecting pipe, a first shell and a second shell, the second shell is arranged in the first shell, the connecting pipe is fixedly connected to the end of the first shell, a connecting ring is fixedly connected to the inner wall of the first shell, and the connecting ring is fixedly connected to the inner wall of the second shell. The second shell is fixedly connected to the inner wall of the connecting ring, the top end of the first shell is fixedly connected with a gas conveying pipe, and the gas conveying pipe extends to the gap between the first shell and the second shell. The sealing piston and the sealing seat are in sliding fit to form a dynamic sealing structure, when no air pressure exists, the spring pushes the sealing piston to be arranged on the side wall, located above the strip-shaped opening, of the sealing seat in a pressed and attached mode, a grinding aid channel is blocked, and leakage is prevented; the sealing piston moves to open a channel, and automatic control over pneumatic driving and sealing opening is achieved.
