Problems solved by technology

In addition, once the mechanical seal is poorly cooled and lubricated, it will also cause damage if it heats up and heats up. Monitoring the temperature at the end face of the seal to detect problems in time and deal with them is also an important means to maintain the normal operation of the mixer.

Embodiment Construction

[0016] Such as figure 1 Shown:

[0017] Intelligent side-entry mixer that can replace shaft seal with material, including motor 1, reducer 2, frame 3, mechanical seal 4, mounting flange 5, stirring shaft 6, stirrer 7, blocking device 8 and stabilizing device 9 . The reducer 2 is fixed outside the side wall of the kettle through the frame 3 and the mounting flange 5, the motor 1 is installed on the input end of the reducer 2, and the stirring shaft 6 is also the output shaft of the reducer 2 that goes deep into the kettle and is installed in the kettle. The agitator 7 is installed, and the stabilizing device 9 is used for load-bearing to improve the stressed state of the agitator.

[0018] Such as figure 2 Shown:

[0019] The inner hole of the mounting flange 5 is a stepped hole, the small diameter section 51 is tightly matched with the installation cylinder of the mechanical seal 4, and the inner side of the large diameter section 52 is designed with a flushing water dist...

Abstract

The invention relates to an intelligent side-in type stirrer capable of replacing a shaft seal with raw materials. The intelligent side-in type stirrer comprises a motor (1), a speed reducer (2), a rack (3), a mechanical seal (4), an installation flange (5), a stirring shaft (6), a stirrer (7), a stop device (8) and a stabilizing device (9), wherein a distribution ring (53) is connected with an external water source through a flushing water channel (54) designed on the installation flange (5); an open type cut-through kettle interior is formed at a position (14) between a friction end surfaceand the distribution ring (53); a PTC (Positive Temperature Coefficient) thermosensitive protection device guided-in thermistor (12) is arranged at a position, close to the friction end surface, on the inner side of a mechanical sealing static ring (41); the PTC thermosensitive protection device can be connected to an alarm control device. The intelligent side-in type stirrer provided by the invention can be used for replacing the shaft seal with raw materials, maintaining mechanical sealing, diluting a fluid on the friction end surface so as to be good for cooling and lubricating, and monitoring the temperature situation at the position so as to conveniently and timely handle the situation at the same time.

Description

technical field [0001] The invention belongs to the technical field of stirring, in particular to a side-entry stirrer for a kettle. Background technique [0002] Mixers are widely used in biopharmaceutical, petrochemical, fine chemical, water treatment, food and beverage, metallurgical mining and environmental protection industries. A mechanical seal is usually installed between the stirring shaft and the kettle body, and the mechanical seal will be damaged after a period of use and needs to be replaced and repaired. The side-entry mixer of the flue gas desulfurization absorption tower is installed on the side wall of the lower part of the stirring tank. In the past, if the mechanical seal was damaged, the material in the kettle had to be drained before it could be replaced and repaired, which would waste manpower, material and financial resources. In order to solve this problem, we have proposed two solutions: the first is the "stirring device ZL200520075774.7 that can r...
