The specific embodiment
Be described in further detail by following examples below in conjunction with accompanying drawing, but the technology contents that this example is narrated is illustrative, rather than determinate, should not limit to protection domain of the present utility model according to this.
A kind of delivery system of high specific gravity material, comprise the pump housing 3, feed pipe 1, discharge pipe 6, bleeder valve 8, air intake assembly and air outlet valve 2, the pump housing is erect on the ground by embedded iron 13, at the coaxial installation feed pipe in pump housing upper end, inlet valve (be the charging dome valve, do not have label) is installed between the pump housing and feed pipe; Medium position at the pump housing is installed air outlet valve, and air intake assembly is installed on the pump housing and the discharge pipe.Innovative point of the present utility model is:
(1) native system adopts the bottom discharge mode, promptly adopt elbow 11 to connect discharge pipe by flange 10 in the bottom of the pump housing, the fluidization components that also is native system adopts elbow to connect in the bottom of the pump housing, and the elbow helps blanking velocity stable, thereby makes material evenly reach concentrated phase.The fluidisation air intake branch can evenly enter discharge pipe by bleeder valve with the material after the fluidisation.
(2) pump housing of native system has adopted double-decker, i.e. taper discharge nozzle top in the pump housing and the coaxial lining 14 that also is fixed with of the pump housing, formed interlayer between this lining and the pump housing, pump housing air intake branch 4 carries air to enter in the pump housing along interlayer, this conveying air produces a thrust with the fluidisation material when entering the pump housing, push in the discharge nozzle thus, and quicken, realized the operation scheme that low flow velocity starts, high concentration is carried at pump housing fluidisation outlet position.
(3) air intake assembly of native system comprises that total inlet pipe 5, the pump housing air intake branch that is communicated with pump housing interlayer, the fluidisation air intake branch 9 that is communicated with pump housing fluidisation outlet position, the discharging opening air intake branch 12 that is communicated with elbow reach the discharging air intake branch 7 that is communicated with pipeline, each air intake branch all is equipped with air inlet valve separately, and this air inlet valve is regulated the tolerance size by the orifice plate quantity in the control air inlet pipe.
Principle of work of the present utility model is:
1. general introduction
Material is deposited in the hopper of pump housing feed pipe top, and the charging dome valve of P pump is opened, and the material by gravity advances to fall into to be installed in the P pump of hopper below, is delivered to grey storehouse by strength then.When blanking time of upper computer then after, all charging dome valves are closed.After all charging dome valves have all been closed and have been sealed, bleeder valve and inlet open, pressurized air will enter all defeated grey pumps then, and ash is arrived grey storehouse by ducting.After material is transported to grey storehouse, send the signal of delivery duct pressure decay, air inlet valve is closed, and finishes once circulation.
2. system initial state
When system stops and being in when waiting to expect state each valve opening and closing situation as follows:
Figure G2009200986693D00031
Concentrated phase P pump should be empty and be in the zero pressure state.
3. concentrated phase P pump operation process
When starting a delivery cycle, control system will check whether following loop start interlocking condition is satisfied fully:
Program control on the Pneumatic controlled box on the spot/change-over switch places " program control " position on the spot;
System start-up/halt switch on upper places " startup " position;
All inlet dome valves are closed and are sealed;
Ash storehouse manual switchover valve must have one in " opening " position.
When above-mentioned condition is true value, will triggers delivery cycle and move according to following steps:
Step 1: the charging dome valve of the pump housing must be established by cable by corresponding solenoid valve and open.Simultaneously, start material filling back off timer, circulation watchdog timer and minimal circulation cycle timer.Material will fall under gravity in the P pump.
Step 2: finish when excessive filling timer, the charging dome valve of this pump is closed by the corresponding solenoid valve dead electricity.In this process, if material is filled back off timer then, time-delay 0.1S closes the charging dome valve of all T pumps.
Step 3:, carry choker relief valve must establish by cable and open by corresponding solenoid valve when air inlet valve delayed start-up timer is finished.Simultaneously, the fluidization air valve of all concentrated phase P pumps will must be established by cable by corresponding solenoid valve and open.
Attention: the circulation watchdog timer then before, if delivery pressure raise to surpass " pressure of closing the door " (program inside), cooresponding conveying choker relief valve and fluidization air valve are closed.When pressure decay during to " pressure opens the door " (program inside) above valve will open again.
Step 4: material arrives target ash storehouse by ducting.When manifold pressure has dropped to less than 0.03MPa, open the safe transport timer, the safe transport timer then sends to carry and finishes signal, and air inlet valve and fluidization air valve will be closed by the corresponding solenoid valve dead electricity.Start the cycle reset timer.
Step 5: finish when the cycle reset timer, then delivery cycle is finished.
Attention: if in cyclic process, any one starts the interlocking condition and becomes non-true value, and then this circulation is proceeded up to finishing allowing, and system will stop then, becomes true value again up to all startup interlocking conditions.For example, the high charge level meter in target ash storehouse is uncovered during system start-up, if in cyclic process, this level-sensing device is capped, and this condition will be left in the basket and circulation is stopped or resetting.This will instruct by PLC program locking loop start and realize.
Same, when a fault takes place, will allow circulation to carry out next step, end-around carry will be suspended then, and after the interlocking condition reverts to true value, circulation will continue to carry out next step.The cyclical information of next step end-around carry is with locked, and therefore when the interlocking condition became non-true value, circulation can not stop or falling back.Be latched in the last cycle reset timer operational process of circulation and remove.
