Abstract
The utility model relates to an automatic control device capable of preventing a pallet discharging belt from burnout, and belongs to the field of metallurgical machinery. The device can prevent the pallet discharging belt from being burnt out due to over-high discharging temperature when a pallet production process is changed. The device comprises master control room devices (an industrial personal computer and an industrial Ethernet switch), a distribution room device (PLC (programmable logic controller) system) and field detection and control devices (an infrared thermometer and an electronic type regulation water valve). The industrial control room device is used for setting parameters and displaying relevant operating parameters, the field detection device is used for detecting the parameters in field in real time, and a detection signal is inputted into the PLC system to be operated and then compared with a set value so as to drive the cooling water valve to operate automatically. Discharging temperature on the pallet discharging belt is regulated in real time, and the pallet discharging belt is prevented from being burnt out.
Description
Technical field
The utility model relates to a kind of pelletizing production device, belongs to field of metallurgical machine, the anti-automaton that burns of especially a kind of pelletizing outfeed belt.
Background technology
Pellet has the features such as intensity is high, epigranular, of high grade, harmful element content is low, is one of important component part of blast furnace burden.
In the pelletizing production of metallurgy industry, pellet circular cooler is that high temperature pelletizing is cooled to 120 ℃ of following equipment, and its dump skip outlet is rubber conveyer below, is responsible for finished pellet to transport.In pelletizing production process; because production technology changes, central cooler cooling air quantity does not regulate in time; group's bulb temperature of causing entering out covering band is too high and burn covering band; at present in pelletizing production process; the main temperature that relies on site operation personnel scene to determine ball, manual unlocking finished product cooling water valve lowers the temperature to protect out covering band not burnt.Shortcoming: labour intensity is large, because site environment is poor, operating personnel can not timely and effective protection belt.
Utility model content
The technical problems to be solved in the utility model is to provide the anti-automaton that burns of a kind of pelletizing outfeed belt, this device goes out bulb temperature situation according to scene, automatically control out the flow of covering band cooling water valve and water, realization prevents due to pelletizing production process variations, causes that drop temperature is too high burns covering band.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of pelletizing outfeed belt is anti-burns automaton, it is characterized in that comprising industrial computer, regulator cubicle, infrared radiation thermometer and electrical adjustment water valve;
Industrial computer, is arranged on the operating desk in control room, by EPA, is connected with the Programmable Logic Controller in regulator cubicle, shows in real time finished product group ball drop temperature, controls opening and discharge adjusting of discharging cooling water valve;
Regulator cubicle, Programmable Logic Controller and input thereof, output interface are installed in regulator cubicle, the input interface of described Programmable Logic Controller connects infrared radiation thermometer, goes out bulb temperature, by the regulation cooling water inflow of analog output port controlling cooling water valve for Real-time Collection;
Infrared radiation thermometer is arranged on three sections of central cooler discharging openings of pellet circular cooler, for monitoring out in real time bulb temperature;
Electrical adjustment water valve, is arranged on finished product and goes out covering tail, is close on central cooler discharging opening water pipe, regulates in time cooling water inflow, prevents out that covering band burns.
Said apparatus is described further, and described Programmable Logic Controller adopts the S7-300 of Siemens Company.
The beneficial effect that adopts technique scheme to produce is: the utility model sets according to pelletizing production technological requirement the maximum temperature that outfeed belt can bear, according to Site Detection element feedback signal, after programable controller system computing relatively, control to adjust equipment, regulate the flow of cooling water, realize out automatically regulating in real time of covering band top discharge temperature, prevent out burning of covering band, significantly increase outfeed belt life-span, increase work efficiency, reduce labour intensity.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is frame principle figure of the present utility model.
The specific embodiment
1 is known with reference to the accompanying drawings, and the utility model is specifically related to a kind of pelletizing outfeed belt to be prevented burning automaton, specifically comprises industrial computer, regulator cubicle, infrared radiation thermometer and electrical adjustment water valve;
Described industrial computer is arranged on the operating desk in control room, by EPA, is connected with the Programmable Logic Controller (PLC) in regulator cubicle, shows in real time three sections of finished product group bulb temperatures of central cooler.
Programmable Logic Controller (PLC) and input thereof, output interface are installed in described regulator cubicle, the input interface infrared radiation thermometer of described PLC, Real-time Collection goes out bulb temperature, the analog output port connecting electronic formula water adjusting valve of described PLC, water adjusting valve aperture, regulates cooling water inflow in real time.
Described infrared radiation thermometer is arranged on three sections of central coolers, for Real-Time Monitoring, goes out bulb temperature.
Described electronic type water adjusting valve is arranged on out covering band near on discharging opening place water pipe, regulates in real time cooling water inflow, prevents from burning covering band.
Described PLC adopts the S7-300 of Siemens Company.
According to production requirement, on industrial computer, set the maximum temperature that needs outfeed belt to bear, site infrare temperature measurer detects in real time drop temperature outputting standard 4～20mA signal and enters PLC system, in PLC system, through certain computing, draw more afterwards the aperture of on-the-spot electronic type water adjusting valve with set amount, output 4～20mA controls electronic type control valve, regulates the flow of cooling water.By the present invention can significantly increase outfeed belt life-span, increase work efficiency, reduce labour intensity.
