Description

Pneumatic conveying device of hundred thousand-ton dry powder coal ash storage warehouse

Technical Field

The utility model relates to a powder field of carrying especially relates to a wind of hundred thousand tons dry powder coal ash storehouse send device.

Background

When concrete building materials are produced, a large amount of fly ash is used, the fly ash is always conveyed to a production workshop from a storage warehouse by a motor vehicle, a large amount of manpower and material resources are consumed, a large amount of raised dust is generated in the processes of transportation and material pouring, a part of materials are wasted, the environment is polluted, and the body of a worker is greatly damaged; the technical problem which is difficult to solve for a long time is how to avoid the phenomenon that the fly ash can not generate dust during transportation and transportation, reduce the labor intensity of workers and improve the production efficiency.

In view of the above, a pneumatic conveying device for a storage warehouse of dry fly ash of hundred thousand tons is developed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the not enough among the prior art, provide the pneumatic conveying device of a hundred thousand tons of dry powder coal ash storehouse storehouses, the utility model discloses avoided the raise dust phenomenon, reduced the material consumption, avoided environmental pollution, be of value to workman's health, reduced workman's intensity of labour, improved production efficiency.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: an air conveying device of a hundred thousand ton dry powder coal ash storehouse is composed of: the device comprises an air source, an air supply pipe, a conveying pipe, a hose, an air inlet pipe, a valve, a sealing ring, a bracket, a fixing plate, a connecting pipe, a discharging hopper and a discharging pipe; the hopper below sets up the conveying pipeline down, set up the unloading pipe between hopper and the conveying pipeline down, the anterior symmetry in upper end of conveying pipeline sets up a pair of support, support one end evenly distributed fixed orifices, set up the air intake on the conveying pipeline between a pair of support, set up the air-supply line of slope in the air intake, the air intake is exposed to the upper end of air-supply line, set up the sealing washer between the periphery of air intake and air-supply line, air-supply line one side sets up the fixed plate, the below of air-supply line sets up the conveying pipeline, the fixed plate passes through the bolt and is even as an organic whole with a pair of support, hopper one side sets up the wind regime down, the air outlet of wind regime sets up the blast.

And a valve is arranged at the tail end of the air supply pipe.

And a connecting pipe is arranged between the air supply pipe and the lower end of the discharging hopper, and an electromagnetic valve is arranged on the connecting pipe.

The rotary valve is arranged on the material conveying pipe.

The utility model has the advantages that: the fly ash falls into the conveying pipe through the blanking hopper, the air source conveys the fly ash in the conveying pipe to a production workshop through the air supply pipe, and the air flow sent into the blanking hopper through the connecting pipe by the air source can blow away the fly ash accumulated in the blanking hopper, so that the situation that the fly ash cannot be discharged due to accumulation in the blanking hopper is avoided; the angle of the air inlet pipe is adjusted according to actual conditions, so that the airflow in the conveying pipe reaches the maximum flow speed, the fly ash is prevented from being accumulated in the conveying pipe, the normal conveying of the fly ash is ensured by the rotary valve, and the fly ash is prevented from being blown back to the discharging hopper; the utility model avoids the dust raising phenomenon, reduces the material consumption, avoids the environmental pollution, is beneficial to the human health of workers, reduces the labor intensity of the workers and improves the production efficiency; the utility model discloses simple structure, design benefit, convenient operation, safe in utilization, excellent in use effect is fit for generally popularizing and applying.
