Problems solved by technology

[0002] The mixer of the desulfurization tower is an external obliquely inserted mixer. The gravity of the impeller will cause damage and leakage of the O-ring of the machine seal shaft sleeve seal. Stopping the desulfurization tower to replace the machine seal will cause too much loss, and the long-term leakage will corrode the tower wall and cause environmental pollution.

Embodiment Construction

[0010] The leakage elimination device of the shaft sleeve of the mixer machine includes a disc 1 and a pipe body 2. A circular hole with a diameter larger than the shaft of the mixer is processed in the center of the disc, and a bolt hole located on the same circle is also processed on the disc.

[0011] In the leak-proof device for the shaft sleeve of the mixer, the disk 1 is also processed with a boss 6, and the center of the boss 6 is processed with a through hole with a diameter larger than the mixer shaft.

[0012] In the specific implementation, (1) Find a pipe body with a length of 150mm, use a 20mm thick steel plate to draw a circle with a diameter larger than the diameter of the pipe body 60mm, cut along the drawn line to make a disc, and then use the disc to circle Draw a circle with a diameter 30mm larger than the diameter of the pipe body with the point as the center, take 4 points symmetrically on the drawn line, draw 4 bolt holes of Φ18mm, and process a boss on th...

Abstract

The invention relates to a mechanical seal shaft sleeve leakage stoppage tool, in particular to a stirring machine mechanical seal shaft sleeve leakage elimination device. The stirring machine mechanical seal shaft sleeve leakage elimination device comprises a disc and a pipe body, wherein the disc center machining diameter is larger than a round hole of a stirring machine shaft; a bolt hole located at the same circle is further machined in the disc; a boss is further machined on the disc; and the boss center machining diameter is larger than a through hole of the stirring machine shaft. By means of the stirring machine mechanical seal shaft sleeve leakage elimination device, when the leakage problem of a mechanical seal shaft sleeve is solved, a pipe body is added outside the mechanical seal shaft sleeve and filled with padding, the padding is compacted and sealed through the disc at the tail, and the purpose of leakage stoppage is achieved.

Description

technical field [0001] The invention relates to a leak-stopping tool for a mechanical machine-sealed shaft sleeve, in particular to a leak-eliminating device for a mechanical-sealed shaft sleeve of a mixer. Background technique [0002] The desulfurization tower mixer is an external obliquely inserted mixer. The gravity of the impeller will cause damage to the O-ring of the mechanical seal shaft sleeve seal and leakage. Stopping the desulfurization tower to replace the mechanical seal will cause too much loss, and the long-term leakage will corrode the tower wall and cause environmental pollution. Contents of the invention [0003] In order to eliminate leaks without stopping the desulfurization tower, the present invention provides a leak-eliminating device for the seal shaft sleeve of the mixer, which does not affect the rotation of the mixer after the leak is eliminated. [0004] The present invention is realized by adopting the following technical scheme: the leak-proo...
