Description

Gear ring grease injection device of scraping machine

Technical Field

The utility model relates to the technical field of granulation machines, in particular to a gear ring grease injection device of a scraping machine.

Background

The scraping machine is key equipment of a granulating system of the urea production device and is used for scraping urea in the granulating tower to enable the urea to flow out from a discharging hole of the granulating tower to be fed to a belt. Because the gear ring driving the scraper to run is arranged at the bottom of the granulating tower, the operating environment temperature is high, dust is large, lubricating oil is easy to pollute, and the probability of failure of the gear ring is high. If a failure occurs, the entire evaporation and pelletizing system will be shut down. Therefore, every time the scraper runs for a period of time, usually 3 months, an operator needs to enter the bottom of the pan through a small door of a lower air window of the prilling tower, and then enters an overhaul hole below the scraping arm through a manhole of the scraping arm to inject grease into the gear ring. The primary problem in the grease injection process is the safety problem, the operation space in the scraping machine is narrow, the overhaul space is less than 1 cubic meter, the diameter of a scraping arm manhole communicated with the overhaul space is only about 40cm, and an operator can possibly generate choking risk in the overhaul hole; before entering the scraper, operators need to contact related departments to transact the operation ticket of the limited space and conduct gas analysis on the narrow operation space in the scraper until the operation ticket is qualified. Secondly, before manual grease injection, the urea evaporation system is firstly switched to a material circulation system, the material scraping machine is stopped, power is cut off through power supply and power failure, and then an operator can enter the bottom of the pot. The operator needs to lift the grease barrel to enter and exit, special monitoring assistance is needed in the whole process, grease can be scattered to cause secondary environmental pollution, so that the operator needs to clean the inner space after the grease injection is finished, the operator can withdraw the grease through the scraping arm manhole and then fix the scraping arm manhole through the bolt to seal the scraping arm manhole, so that impurity particles can not enter the scraping arm, the urea production space is isolated from the gear ring, the material is prevented from entering the gear ring, and the normal operation of equipment is prevented; and then exits through the windward window small door. And after all is finished, the power transmission to the scraper is resumed, the scraper is started, and the evaporation system and the granulating system normally operate.

The operation space of the fat injection process is narrow, potential safety hazards exist, and the life safety of staff in a production system is threatened; the steps are complicated, the operation is not easy, and at least one hour is needed; one grease injection can cause the energy consumption loss of the system to be nearly five thousand yuan.
