The utility model is more because of the parts of forming, for can be with its structure and whole equipment operation logic narration clearer, now it be divided into the following aspects describe:
One, apparatus for distributing:
Its effect is to be distributed to the coal rod in the main tower equably, it comprises feed belt machine 2, electronic discharger 11, stock guide 10, cutting plate 19, its mutual annexation is as follows: feed belt machine 2 is installed in main tower 3 tops, feed belt machine top is equipped with a plurality of electronic dischargers 11 (volume according to main tower can be provided with 3～8), a stock guide 10 all is equipped with in each electronic discharger below, and the stock guide bottom is equipped with cutting plate 19.Its operation principle is as follows: the coal rod is delivered to main tower top through feed belt machine 2, evenly load and unload on the stock guide 10 by a plurality of electronic dischargers 11 again, the coal rod slips on the cutting plate 19 from stock guide because of the gravity effect, be divided into two strands of material by cutting plate again and fall into main tower 3, realize the purpose of uniform distribution.
Illustrate: in the process that realizes coal rod uniform distribution, electronic discharger plays a part crucial, because wanting one material on the feed belt machine evenly to be divided into the multiply material unloads, must realize by the semi-automatic adjustment function of electronic discharger, the concrete structure of electronic discharger is as shown in Figure 4: electric pushrod 20 is fixed on the top of feed belt machine 2 by bracing frame 21, plough formula sub-material scraper plate 22 is fixed on the sliding panel 23 by bolt connecting mode, sliding panel 23 is connected on the adjusting nut 24 of electric pushrod 20, simultaneously, the control telegraph key of electric pushrod 20 is installed on the electrical control cubicles in the control room, ground.During work, only need in the control room, ground, to press the starting on the electrical control cubicles or stop the start-stop that telegraph key can be controlled electric pushrod.Adjusting nut by electric pushrod drives plough formula sub-material scraper plate, thereby realizes the purpose of ground centralized Control operation, has guaranteed the stable of moulded coal dries quantity.
Two, drying plant:
Its effect is with coal rod oven dry, and moisture content is dried to moisture content far above 10% wet coal rod is 2%～4% dry coal rod.It comprises main tower 3, interior air channel 13, outer air channel 9, air-introduced machine 8, import air channel 17, heating stove 16.Its interconnected relationship is as follows: interior air channel 13 is distributed in the main tower 3, and interior air channel links to each other with outer air channel 9, and outer air channel 9 links to each other with air-introduced machine 8, and air-introduced machine 8 links to each other with import air channel 17, and import air channel 17 links to each other with heating stove 16.Its operation principle is: hot blast is provided by heating stove, is sucked by air-introduced machine through the import air channel, in outer air channel is sent in the air channel, and the aperture ejection from the interior air channel again contacts, evaporates and take away moisture content in the coal rod with coal rod in the main tower, makes that coal is excellent dries.
Three, discharging equipment:
Its effect is that the coal rod after the oven dry is exported from main tower.It comprises hopper 5, vibratory tray 6, outfeed belt machine 4, and its interconnected relationship is: hopper 5 is installed in main tower 3 bottoms, and vibratory tray 6 is equipped with in the hopper bottom, and outfeed belt machine 4 is contained in the vibratory tray bottom.Its operation principle is: the coal rod is slipped on the vibratory tray from hopper because of deadweight, and when the vibrating motor on the vibratory tray was opened, material quilt on the vibratory tray is shaken to be fallen on the outfeed belt machine, by the outfeed belt machine it is exported again.
Illustrate: vibratory tray is the critical component that this system's material of control unloads, stops, its structure is shown in figure five: vibrating motor 25 is installed in tray rack 26 sides, be welded with pallet 27 on the tray rack, pallet becomes-5 ° of angles to arrange with horizontal plane, on four angles of tray rack spring 28 is installed, spring is supported on the supporting leg 7.When the needs discharging, then open vibrating motor, the pallet that is supported on the spring vibrates with vibrating motor, and material falls from pallet, realizes the purpose of discharging; When stopping to vibrate, because of having frictional force between material and pallet, material can not glide, thereby realizes stopping the purpose of discharging.
Four, the automatic compensation equipment of hot blast temperature:
The desirable EAT of coal rod oven dry is between 140 ℃～160 ℃, and when EAT was higher than 180 ℃, the coal rod in the drying tower was with regard to the pyrophoricity accident that catches fire easily.The purpose of native system is controlled at EAT in 160 ℃ exactly automatically, avoids the excellent pyrophoricity accident that catches fire of coal.The automatic compensation equipment of hot blast temperature is made up of mechanical transfer equipment, EAT checkout equipment, control panel: first is the mechanical transfer part, and it realizes its motion by an electronic butterfly valve; Second portion is the outlet and inlet temperature detection part, and it is made up of thermocouple, lead etc.; Third part is automatically controlled part (it comprises information input, information processing, signal output, feedback information).Its interconnected relationship is as follows: the electronic butterfly valve 15 in the mechanical transfer equipment is installed in being connected on the air channel 17 of heating stove 16 and air-introduced machine 8, and air-introduced machine 8 links to each other with outer air channel 9, on the outer air channel 9 EAT checkout equipment 18 is installed; Its operation principle as shown in Figure 2, hot blast by heating stove 16 outside import air channel 17 is introduced by air-introduced machine 8 in the air channel 9, when the temperature in the outer air channel is higher than 170 ℃, its EAT checkout equipment 18 can be passed to electric-control system with its temperature value of sensing, electric-control system is given electronic butterfly valve 15 with electrical signal transfer after information processing, electronic butterfly valve is opened, cold wind (natural air) is inhaled into the import air channel 17 from butterfly valve and mixes with hot blast, its temperature is reduced, EAT checkout equipment 18 just temperature value feeds back to electric-control system, electric-control system sends the size of signal of telecommunication control electric butterfly valve valve opening after information processing, thereby the soakage of control cold wind repeats above flow process and reaches temperature automatically controlled purpose.
Five, watch-dog:
Monitoring system is the comprehensive of surveillance and control system, and its effect is the baking operation of finishing the coal rod that makes above four systems can connect mutually, coordinate mutually.It comprises camera 12, lead, display, leaving air temp checkout equipment 14 (containing thermocouple, lead, instrument), electrically-controlled component (electric control element that contains the air-introduced machine of feed belt machine, outfeed belt machine, vibrating motor, electronic discharger, electronic butterfly valve).Their installation site and act on as follows: camera 12 is installed in main tower 3 upper ends, display is installed on the indoor electric cabinet of terrestrial operation, camera with each electronic discharger discharging on the accumulation situation of coal rod on the main tower and the main tower whether evenly the vision signal of discharging situation pass on the indoor display of terrestrial operation through lead; 14 fens a plurality of main tower 3 tops that are installed in of leaving air temp checkout equipment, its effect are the temperature values that is used to respond to coal rod in the main tower, and it passes to its temperature signal of sensing on the instrument that is installed in the indoor electric cabinet of terrestrial operation through lead.The operator can open corresponding electric control element according to above these vision signals and temperature signal, sends corresponding operational order, makes the normal orderly operation of whole system.
