Conveying condition.
The cleaning dredges plugging road B2 and is connected with air source by shut-off valve, clears up the shut-off valve and electricity dredged on the B2 of plugging road
Gas control system 4 is electrically connected.
In the technical program, material receiving ports of the transfer pipeline B12 with hydraulic pressure for silo 1 is separated from each other, so that transition case
Abrasive material flow at discharge port 9 is maintained at a more constant state.
The working method of second outlet control mechanism A1 is referring to following first outlet control mechanism B1's in the technical program
Working method, details are not described herein again.
Second of realization method of 1.2 second outlet control mechanism A1
As shown in Fig. 2, the second outlet control mechanism A1 is sand supplying valve A13.
The sand supplying valve A13 includes arc valve A15 and third driving mechanism A14, the third driving mechanism A14 specific
It is selected as cylinder, cylinder is fixed by the bracket on transition case 8, and the control terminal of cylinder is electrically connected with electric control system 4, cylinder
Piston end be connected with arc valve A15；Cylinder driven under the action of electric control system 4 arc valve A15 movement with
Control the opening and closing of transition case discharge port 9.
The third realization method of 1.3 second outlet control mechanism A1
As shown in figure 4, the second outlet control mechanism A1 includes sand supplying valve A13 and sand supplying threeway A16, the sand supplying three
An import of logical A16, which is provided with, inhales sand mouth, another import dredges plugging road A18 with compressed air and is connected, sand supplying threeway A16's
Outlet is provided towards sand export of the hydraulic pressure for 1 feed inlet of silo.
The structure of sand supplying valve A13 is referring specifically to the record of second of realization method, and details are not described herein again.
Sand supplying threeway A16 easily can carry out any switching laws between conveying operation and pipeline cleaning.
The suction sand mouth of sand supplying threeway A16 uses bell-mouth structure of air, the abrasive material for mouth outflow of shaking out can be all received, due to transition
Case discharge port 9 is inhaled sand mouth with the sand supplying threeway A16 in the technical program and is detached, to defeated residing for sand supplying threeway A16 discharge ports
The resistance of sandpipe road A12 and the variation for inhaling the suction force at sand mouth A17, do not have shadow to the abrasive material flow at transition case discharge port 9
It rings.
The compressed air dredges and is equipped with the air valve being electrically connected with electric control system 4 on the A18 of plugging road, and air valve is for controlling
The break-make of compressed air processed realizes the switching of abrasive material conveying and pipeline clearing function.
Below in conjunction with the accompanying drawings 4, the work to sand supplying valve A13 and sand supplying threeway A16 the second outlet control mechanism A1 constituted
Process is described further：
1) it will add in sandbox 7 before operation and fill abrasive material, abrasive material will automatically flow into transition case 8, due to transition case 8 and big gas phase
Connection, in conjunction with the inherent characteristic of abrasive material, abrasive material will not be steady to make the abrasive material in transition case 8 have from 8 spilling suitable for reading of transition case
Fixed material position and gas permeability；
2) according to the operating mode of abradant jet surface preparation operation, suitable sand export bore is selected, transition case is replaced and goes out
The mouth that shakes out at material mouth 9；Meanwhile the air valve for making the compressed air being connect with sand supplying threeway A16 dredge plugging road A18 is in closing shape
State；
3) by the cylinder movement of 4 remote opening sand supplying control valve A13 of electric control system, arc valve A15 is pulled, is made
Transition case discharge port 9 opens wide, shake out mouth outflow of the abrasive material from transition case discharge port 9, the supply operation for the abrasive material that hops to it；
4) when encountering transfer pipeline A12 abnormal, blocking, electric control system 4 can be passed through immediately and remotely closes sand supplying control
Valve A13 processed makes arc valve A15 downward actuations to close transition case discharge port 9, and transition case 7 stops feed at this time, opens simultaneously
Compressed air dredges the air valve on the A18 of plugging road, is cleared up transfer pipeline 12 with compressed air, until Abnormal Blocking situation is clear
It removes, then restarts dry feeding abrasive material conveying operation；
5) when operation needs to stop, sand supplying control valve A13 is first closed in the way of step 4), and it is empty to be then turned on compression
Gas dredges the air valve on the A18 of plugging road, clears up remaining dry grinding material in transfer pipeline and sand supplying threeway A16 with compressed air, avoids
Residual siltation；
6) air valve on the thin plugging road A18 of compressed air is closed, a whole set of dry grinding material is completed and conveys operation.
In the present embodiment plus 7 volume of sandbox is determined according to the quantity of its underpart discharge port, can be met common dry grinding material and be penetrated
Flow operation 3 hours or so；In order to ensure dry feeding abrasive material is uniform and stable, be not in it is sometimes fast and sometimes slow, when it is more when few show
As to influence the effect quality of abradant jet surface preparation operation, the present apparatus uses the transition case design of original creation and goes out
Sand mouth with inhale sand mouth separate design (material position is essentially identical always during transition case makes sand supplying, sand export with inhale sand mouth point
From eliminating sand suction pipe roadlock power and change influence to sand supplying flow)；Sand export, that is, transition case discharge port 9 is then by electropneumatic
Cylinder executes remote control open and close；Sand export can be very easy according to the demand of abradant jet operation replacement different bores
Shake out mouth, reaches different feeding abrasive material rates；Inhaling sand mouth then uses trumpet type left-hand thread nut check to design, can be quickly simple
Just it is safeguarded.After the operating mode that abradant jet operation is determined, the suitable mouth that shakes out is selected and replaces, it is then that abrasive material is defeated
Send pipeline with inhale sand mouth connect, remote opening sand export hop to it abrasive material conveying supply.After the completion of operation, closing is shaked out
Mouthful, it opens air valve and clears up inhaling remaining dry grinding material in sand mouth and transfer pipeline, finally close air valve, complete entire dry grinding
The supply of material conveys operation.
2. not setting the dry grinding material transport system of transition case
As shown in fig. 7, the dry grinding material transport system in the technical program includes adding sandbox 7.
As shown in figs. 8-10, described plus sandbox 7 lower part is exported equipped with abrasive material, and is added and be provided at sandbox discharge port 10
Second outlet control mechanism A1.
There are three types of realization methods by second outlet control mechanism A1 in this transport system, are described below：
The first realization method of 2.1 second outlet control mechanism A1
As shown in Fig. 9,5a, the knot of second outlet control mechanism A1 and first outlet control mechanism B1 in the technical program
Structure is identical, and the two includes discharge control valve and threeway B10；The discharge control valve includes valve B 4, spool B5, rotation
Needle B6, the first driving mechanism B9, valve seat B8, the second driving mechanism B7.
