Embodiment 1

[0010] Example 1 Composition and function of an electrical automatic control system for a cement raw material pneumatic conveying system:

[0011] Electrical automatic control system includes PLC programmable control system 1, industrial computer or DCS system 2, fan motor 3, pneumatic discharge valve 4, high level gauge 5, low level gauge 6, pneumatic plug valve 7, signal transmission cable 8. The weighing sensor 9 and the mass flow meter 10 are composed of the electric automatic control system which is centralized controlled by the PLC programmable control system 1, and its material-gas ratio is 32-35. Equipment regulation. Described industrial control computer or DCS system 2 display the various operations of each control point, monitor drawing respectively with interface; And status; with instrument screen list, system overview screen, alarm overview screen, parameter setting screen. The high-level material level gauge 5 and the low-level material level gauge 6 are ins...

Embodiment 2

[0012] Example 2 The working process of the electric automatic control system of a cement raw meal pneumatic conveying system:

[0013] The industrial computer or DCS system 2 uses the PLC programmable control system 1 to measure the data through the load cell 9 and the mass flow meter 10 according to the material-gas ratio, and sends the material from the hopper to the rotary feeder according to the ratio of the material-gas ratio of 32-35. Cement raw meal is sent to the lower end of the air chute into the bin, and the high-level material level gauge 5 and the low-level material level gauge 6 are installed on the silo for controlling the material level of the silo. The action of the pneumatic flapper valve 7 is used to open and close the outlet of the silo, so as to transport the cement raw meal to the user.

Abstract

The invention relates to an electric automatic control system of a pneumatic conveying system for raw cement materials. The electric automatic control system comprises a PLC (programmable logic control) system 1, an industrial personal computer or DCS (distributed control system) 2, a fan motor 3, a pneumatic discharge valve 4, a high level indicator 5, a low level indicator 6, a pneumatic gate valve 7, a signal transmission cable 8, a weighing sensor 9 and a mass flowmeter 10. The electric automatic control system is characterized by being controlled centralizedly by the PLC system, the ratio of material to air is 32-35, and the system performs regulation of line pipe equipment according to the ratio of material to air. The electric automatic control system has the advantages that action correlation of the related components is realized in the control process, and the actions are executed automatically; optimal control on the air to material ratio is ensured in the conveying process, and operating cost is lowered; the control system is a comprehensive digital system integrating monitoring and operation and operators can operate, monitor and record through monitor pictures on a touch screen in an operation room.

Description

technical field [0001] The invention relates to an electric automatic control system of a cement raw meal pneumatic conveying system, especially suitable for the electric automatic control of a cement raw meal pneumatic conveying system with a high feed inlet, a low discharge outlet, and a relatively short conveying distance The system belongs to the field of electric automatic control system of pneumatic conveying technology. Background technique [0002] Cement raw material is made of calcareous raw materials, clay raw materials and a small amount of correction raw materials (sometimes mineralizers, seeds, etc. are added, and coal is added during shaft kiln production) in proportion, and ground to a certain fineness, called cement. Raw material. The traditional conveying of cement raw meal and the pneumatic conveying of cement raw meal with high and low head difference are mostly carried by the screw conveyor with power. The screw conveyor is installed at a certain inclin...
