The main shaft of the tug is generally matched with a semicircular bearing bush to transmit torque, so that the requirements on lubrication and cooling of the bearing bush are also very high. The bearing bush is fixed on the hemispherical bush seat and is fixed by the fixed pressing block, so that the bearing bush is prevented from moving or moving relative to the hemispherical bush seat. The normal operation of the tug mechanism is also one of important factors for ensuring the normal operation of the whole rotary kiln, once the tug system fails to operate, the whole rotary kiln system needs to stop operating, and major safety accidents are avoided.
The temperature rise of the bearing bush is a problem to be noticed during the operation of the rotary kiln. The tug lubrication oil is not changed or maintained in place for a long time, the viscosity of the lubrication oil is reduced, oil emulsification or dust impurities are contained in the oil, the sealing of a tug shaft is poor, the oil level is reduced due to the serious oil leakage, or the temperature of a bearing bush is increased due to the falling off of a lubricating oil spoon, the bearing bush is likely to generate heat, if the tug of the rotary kiln is injured and generates heat, the rotary kiln can reach the use condition after being ground in for a long time, the rotating speed needs to be reduced in the grinding process, the oil is frequently changed, and the production is influenced and the environment. Therefore, the research and development of a device which can ensure the temperature of the lubricating oil of the tug boat tile to be reduced and can purify the lubricating oil at any time are very important.

In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides an automatic heat sink of rotary kiln axle bush tow boat, includes the oil pipe of being connected with the tow boat, return oil pipe, temperature monitoring system, driving system, PLC control system and the cooling system who is connected with the tow boat, its characterized in that: the temperature monitoring system comprises a temperature probe arranged in the tug; the power system comprises an oil pump arranged on the oil return pipe; the cooling system comprises an external oil tank connected with the oil outlet pipe and the oil return pipe and a radiator for cooling the oil tank, wherein the oil tank is rectangular, a cooling layer is arranged around the outside of the oil tank, two partition plates are arranged at the bottom layer inside the oil tank, and the radiator is connected to a circulating loop of the cooling layer; and the temperature monitoring system, the radiator of the cooling system and the power system are electrically connected with the PLC control system.
The technical scheme of the invention is further improved as follows: the height of the partition is one third of that of the oil tank.
The technical scheme of the invention is further improved as follows: and a filter screen is arranged at the port of an oil return pipe in the oil tank.
The technical scheme of the invention is further improved as follows: the oil storage capacity of the oil tank is three times of the oil storage capacity of the tug boat.
The technical scheme of the invention is further improved as follows: the cooling layer is internally provided with circulating water, the radiator is connected to a circulating loop of the circulating water, and the radiator cools the circulating water.
Due to the adoption of the technical scheme, the invention has the technical effects that:
according to the automatic cooling device for the rotary kiln bearing bush tug, a temperature monitoring system monitors the temperature of lubricating oil in the tug in real time, signals are transmitted to a PLC control system, when the temperature of the oil in the tug is higher than a set temperature, the PLC control system controls an oil pump of a power system to be started, and meanwhile, a radiator of a cooling system is controlled to be started to cool the lubricating oil; when the temperature is reduced to the set low temperature, the PLC control system controls an oil pump of the power system to be closed, and meanwhile, a radiator is also closed; set up the baffle in the outside oil tank, bottom oil is in quiescent condition relatively because the baffle effect, and in lubricating oil flowed into the oil tank, the oil velocity of flow slowed down, impurity and wherein moisture content can sink in the baffle, played the edulcoration effect.
