Description

Technical Field

[0001] The utility model relates to the technical field of anti-condensation in a bearing chamber of a reducer of a vertical reactor, in particular to an anti-condensation device in a bearing chamber of a reducer of a vertical reactor. Background Art

[0002] Vertical reactor is a kind of reaction vessel commonly used in chemical industry, and its main structure is a cylindrical design placed upright. Vertical reactor is widely used in chemical reaction, mixing, fermentation, extraction and other processes in chemical, pharmaceutical, petroleum, food and other industries. When the reducer bearing room of vertical reactor is working normally, it is in a semi-closed state with poor air circulation. The air under natural conditions is composed of a small amount of dust, water vapor and absolutely dry air. At a higher temperature, the water vapor contained in the air is precipitated in the form of liquid water.

[0003] If air with high humidity and relatively high temperature hits a solid surface with relatively low temperature (lower than the dew point temperature of the air under this condition), condensation will occur, which will cause a certain amount of liquid water to be produced in the bracket of the vertical reactor reducer, causing the reducer lubricating oil to emulsify and deteriorate. The maintenance-free bearings in the bracket will fail to make lubrication failure, resulting in abnormal noise, which seriously affects the normal production. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide an anti-condensation device for the bearing chamber of a vertical reactor reducer. By adding dust-proof breathing caps and air vents arranged up and down, air convection is formed in the bracket part to effectively avoid the generation of self-condensation; at the same time, if condensation is generated, the air vents arranged downward can effectively drain it to prevent condensation from accumulating in the internal enclosed space and seeping into the reducer lubricating oil, causing the lubricating oil to be emulsified, thereby reducing the equipment failure rate and achieving better economic benefits.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The anti-condensation device for the bearing chamber of the reducer of the vertical reactor comprises a driving motor, which is connected to the reducer through a bracket. A maintenance-free bearing is arranged inside the bracket. A dustproof breathing cap and a vent are arranged on the bracket. The dustproof breathing cap is located above the vent.

[0007] The bracket is used to support the drive motor and protect the maintenance-free bearing. The vent is set obliquely downward to prevent external liquid from entering the bracket.

[0008] A motor protection cap is arranged above the driving motor, and a motor protection cap flow guide port is arranged on the motor protection cap.

[0009] The inside of the dustproof breathing cap is provided with an inclined dustproof ventilation plate, the outer side of the inclined dustproof ventilation plate is provided with a dustproof barrel, and the inclined dustproof ventilation plate is tangent to the inner wall of the dustproof barrel.

[0010] The dustproof barrel vertical wall is provided with air inlet and outlet holes, a vibrator and an impurity discharge port, the impurity discharge port is located above the inclined dustproof ventilation plate, and the air inlet and outlet holes are located above the impurity discharge port.

[0011] The inclined dustproof ventilation plate is provided with a movable scraper, and the movable scraper is connected with a pull rod.

[0012] A top cover is arranged on the top of the dustproof barrel, and the bottom of the dustproof barrel is connected to the bracket through a guide pipe.

[0013] The guide port of the motor protective cap is located in the vertical direction of the connection line between the dustproof breathing cap and the vent, so as to prevent the accumulated water on the top cover from falling onto the dustproof breathing cap and the vent.

[0014] The reducer of the vertical reactor is connected to the motor through a plum blossom coupling, which is located inside the cylindrical bracket in the middle of the reducer. The interior of the reducer bracket is a nearly closed space, and two 10mm convection holes are opened at 180° at the bottom of the bracket. The convection holes are connected to 10mm guide pipes through tapping. The guide pipes are arranged upward and obliquely downward respectively. A dust-proof breathing cap is added to the top of the guide pipe arranged upward.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] By adopting the utility model of the anti-condensation device for the bearing chamber of the reducer of the vertical reactor, dust-proof breathing caps and air vents arranged up and down are added to form convection of air in the bracket part, thereby effectively avoiding the generation of self-condensation; at the same time, if condensation is generated, the air vents arranged downward can effectively drain it to prevent the accumulation of condensation in the internal closed space and the infiltration into the lubricating oil of the reducer, thereby emulsifying the lubricating oil and reducing the equipment failure rate, thereby achieving better economic benefits.
