Abstract
The invention relates to a pneumatic conveying system for raw cement materials, in particular to an air-chute pneumatic raw cement material conveying system with a high feed inlet and a low discharge outlet and short conveying distance. The conveying system comprises a fan 1, a pneumatic discharge valve 2, a manual gate valve 3, a hopper 4, an air chute 5, air exhaust filter caps 6, a receiving bin 7, a pneumatic gate valve 8 and an electric control system 9. The pneumatic conveying system is characterized in that the raw cement materials slide down on the chute surface, with a breathable layer, of the air chute 5 along the airflow so as to be conveyed, and continuous conveying can be realized. The pneumatic conveying system has the advantages of being simple, small in abrasion to the raw materials and less in system power consumption.
Description
Technical field
The present invention relates to a kind of air-transport system of cement slurry, be particularly useful for having an inlet point high position, discharging opening low level, fed distance, compared with the air-transport system of a kind of cement slurry of the cement slurry of short distance, belongs to Pneumatic Conveying Technology field.
Background technology
Proportioned by calcareous raw material, clay raw material and a small amount of correction material (sometimes also add mineralizer, crystal seed etc., also want coal when shaft kiln is produced), grinding, to the cement slurry of certain fineness, is called cement slurry.The conveying of traditional cement slurry and have the conveyor screw conveying of Geldart-D particle many employings drive of cement slurry of high and low potential difference, conveyor screw is when mounted in certain inclination angle, and such mode of movement has certain grinding loss to raw material.
Summary of the invention
The object of the invention is to improve the deficiencies in the prior art, the mode of movement that a kind of grinding loss is little, consumption of power is little is provided, namely adopt the air-transport system of a kind of cement slurry that operating cost is low.The object of the present invention is achieved like this
:the present invention relates to a kind of air-transport system of cement slurry, be particularly useful for having inlet point high-order, discharging opening low level, fed distance is compared with the air-transport system of a kind of cement slurry of the cement slurry of short distance, delivery system comprises blower fan 1, pneumatic bleeder valve 2, hand operated gate valve 3, hopper 4, air flume 5, exhaust filter cap 6, rewinding storehouse 7, pneumatic gate valve 8, electric control system 9 forms, it is characterized in that cement slurry glides to realize conveying having on air-permeable layer inclined trough surface of air flume 5 with air-flow, can a kind of air-transport system of cement slurry of continus convergence.Described blower fan 1 is for providing source of the gas.Described pneumatic bleeder valve 2 is used for supplying cement slurry, is arranged on the high order end of air flume 5.The air that described exhaust filter cap 6 mixes with cement slurry for discharging discharging opening.Described electric control system 9 comprises PLC programmable control system, industrial computer, also other DCS control system accessible.
the invention has the beneficial effects as follows:
1, delivery system is simple;
2, little to raw material abrasion, system dynamic consumes little.
Accompanying drawing explanation
Fig. 1 is the structural representation sketch of the air-transport system of a kind of cement slurry provided by the invention:
1-blower fan 2-pneumatic bleeder valve 3-hand operated gate valve 4-hopper 5-air flume 6-is vented filter cap 7-rewinding storehouse 8-pneumatic gate valve 9-electric control system.
Detailed description of the invention
the air-transport system composition of embodiment 1 one kinds of cement slurries and effect:
Delivery system comprises blower fan 1, pneumatic bleeder valve 2, hand operated gate valve 3, hopper 4, air flume 5, exhaust filter cap 6, rewinding storehouse 7, pneumatic gate valve 8, electric control system 9 form, it is characterized in that cement slurry glides realizes carrying having on air-permeable layer inclined trough surface of air flume 5 with air-flow, is can a kind of air-transport system of cement slurry of continus convergence.Blower fan 1 is for providing source of the gas.Pneumatic bleeder valve 2 is used for supplying cement slurry, is arranged on the high order end of air flume 5.The air that exhaust filter cap 6 mixes with cement slurry for discharging discharging opening.Electric control system 9 comprises PLC programmable control system, industrial computer, also other DCS control system accessible.
the working process of the air-transport system of embodiment 2 one kinds of cement slurries:
After cement slurry is added by cement slurry bucket 4, the cement slurry import layer of air flume 5 is entered after pneumatic bleeder valve 2, the air-flow of blower fan 1 enters the air intlet layer of air flume 5, and cement slurry glides to realize conveying in having on air-permeable layer inclined trough surface of air flume 5 with air-flow.Fall into rewinding storehouse 7 after sliding to low order end by high order end, and discharge via the outlet of rewinding storehouse pneumatic gate valve 8.
