Technical Field

The utility model relates to the technical field of fans, in particular to a kiln head and kiln tail coal feeding air suspension fan.

Background

The main raw materials of cement production comprise clinker, gypsum and some auxiliary correction raw materials, wherein, the clinker accounts for 50 percent, so the cement strength is affected after the quality of clinker calcination is directly affected in the clinker production, the calcination temperature in the clinker production mainly depends on the coal supply of a kiln head burner and the coal supply of a kiln tail preheater, the kiln head burner must supply heat to the kiln before feeding, when the temperature in the kiln reaches more than 1000 ℃, the kiln tail continuously supplies coal according to the feeding amount, the whole system is ensured to keep a high temperature state, raw materials are subjected to a series of suspension preheating decomposition by a kiln tail system before entering the kiln, the decomposed raw materials enter the kiln and pass through the kiln head at the high temperature of 1700 ℃, the materials are melted at 1450 ℃, are conveyed into a grate cooler through a cooling belt under the driving of the rotation of the rotary kiln to be subjected to extreme cold conveying into a clinker storage warehouse, and the continuous operation of a head-tail coal blower is an important guarantee and basic condition for ensuring the high-quality clinker production, the ordinary fan of original design, long-time operation wind pressure is unstable, and the trouble is frequent, and cost of maintenance is high, and the noise is big.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a kiln head and kiln tail coal feeding air suspension fan to solve the problems in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme: kiln head, kiln tail send coal air suspension fan, including bellows, be equipped with the casing in the bellows, be equipped with the motor in the casing, the output of motor is fixed with the one end of even axle, the other end of even axle stretches out the casing and is connected with fan impeller, be equipped with air-supply line and play tuber pipe on the casing, install the muffler on the play tuber pipe, the other end of even axle passes through air bearing and is connected with the casing.

Further, a cooler is arranged in the air box.

Further, be equipped with the controller in the bellows, motor and cooler all electric connection are in the controller.

Furthermore, a filter screen is arranged in the air inlet pipe.

Compared with the prior art, the utility model has the beneficial effects that:

the fan impeller enters air into the shell through the air inlet pipe when the device is in operation, the fan impeller sends the air into equipment through the air outlet pipe under the action of high-speed centrifugation, the fan adopts air suspension without oiling lubrication, only daily cleaning of a filter screen is needed, and equipment faults caused by long-term operation abrasion of a common fan and bearing damage are effectively solved.
