Detailed description of the invention
The press filter plate drawing method that Fig. 1-Fig. 5 is traditional adopts the work of a set of drawing-plate mechanism, under the driving of motor, is repeatedly performed and takes plate, arm-tie action, and the arm-tie completing whole pressure filter drops the work of filter cake.
Fig. 6-Fig. 7 is three filter plates of the present invention is one group of arm-tie process schematic using connecting line to connect, its work process is, when drawing-plate mechanism often pulls open first piece of filter plate of one group of filter plate, first piece of filter plate pulls open each piece of filter plate of this group successively again through bracing wire, makes the filter cake in each piece of filter plate of this group come off.When first piece of filter plate of this group is near upper one group of last block filter plate, promote upper one group of filter plate Guan Bi, make one group of filter plate close successively from last BOB(beginning of block), after upper one group of filter plate is of completely closed, two groups of filter plates are all immovable, control system monitoring to transship to drive motor, send switching command, make motor reversal, drawing-plate mechanism returns to first piece of filter plate position of next group, what carry out next group takes plate arm-tie action, so circulates, and the arm-tie completing whole the whole filter plate of machine drops the work of filter cake.
Fig. 6-Fig. 7 arm-tie method is disadvantageous in that: plate pulling efficiency is low, easily causes last block filter plate clamping filter cake in every group.Because when often group filter plate is opened, from the first of this group piece of filter plate, this group filter plate is pulled open successively, when first piece of filter plate of this group is near upper one group of last block filter plate, promote upper one group of Guan Bi, one group is made to close successively from last BOB(beginning of block), therefore often last block filter plate in group filter plate is always finally opened, it is also always closed at first simultaneously, this arises that last block filter plate often organized does not have enough opening times to come off for filter cake and operator checks cleaning, thus often there will be clamping filter cake, therefore the time of return of drawing-plate mechanism can only generally be sacrificed, guarantee that last block filter plate also has enough opening times, this just have impact on plate pulling efficiency, therefore, pressure filter each arm-tie cycle wants 5 minutes at the soonest, slow reaches more than 40 minute.
Fig. 8-Figure 12 is the optimization design of the present invention: all filter plates are all connected by connecting line, it is not grouped, realize the filter plate continuous opening of whole pressure filter, the effect of Guan Bi continuously, and be that the filter plate first pulled open first closes, after Guan Bi after the filter plate that pulls open, make the filter cake in all filter plates have enough opening times, be beneficial to filter cake and come off and operator checks cleaning.
When the pressure strip backhaul of pressure filter, it is fixed on No. 1 filter plate on pressure strip and by the traction of connecting line, No. 2 thereafter, No. 3 and No. 4 filter plates can be pulled open successively.After pressure strip resets completely, namely No. 1 filter plate maintains static, and such as Fig. 9, now drive motor starts and rotates forward, chain moves with plate pulling hook and is namely moved to the left to taking plate direction, when plate pulling hook is through No. 1 filter plate, motor rotations enumerator now can be set to 0 by system, and plate pulling hook continues to move to taking plate direction, after drive motor revolution reaches revolution set in advance, drawing-plate mechanism arrives the front taking Board position of No. 2 filter plates, and drive motor stops rotating forward, such as Figure 10.
After taking No. 2 filter plate positions of plate hook arrival, control system can send switching command (being controlled by drive motor revolution counter), drive motor reverses, 2nd piece of filter plate is pulled by plate pulling hook and moves to the 1st piece of filter plate direction, simultaneously, 2nd piece of filter plate also can drive the synchronizing moving together with the 4th piece of filter plate of the 3rd thereafter by connecting line, and keeps the 3rd, the 4th piece of original aperture of filter plate constant, and the 5th piece of filter plate is pulled open by the 4th piece of filter plate also by connecting line.When the 2nd piece of filter plate compresses the 1st piece of filter plate, whole filter plates all can not move again, and control system detects the current overload of drive motor, can provide drive motor and stop the order of reversion, and the arm-tie action of the 2nd piece of filter plate completes.Such as Figure 11.
nullWhen completing of the 2nd piece of filter plate arm-tie action，Control system is by the zero setting again of motor rotations enumerator，Switch motor turns to again simultaneously，Motor is made to rotate forward again，Drawing-plate mechanism moves to taking plate direction again，After drive motor reaches the revolution set，What drawing-plate mechanism arrived the 3rd piece of filter plate takes Board position，Such as Figure 12，Control system provides drive motor rotating forward and ceases and desist order，Control system assign drive motor rotate forward cease and desist order while，Also can assign drive motor commutation，Motor reversal，Plate pulling hook drives No. 3 filter plates to move to the 2nd piece of filter plate direction，Complete the arm-tie task of the 3rd piece of filter plate，When No. 3 filter plates compress No. 2 filter plates，All filter plates are immovable again，Drive motor transships again，Control system orders again to rotate forward，Drawing-plate mechanism commutation is moved toward taking plate direction，So constantly automatically repeat，Until all filter plates all pull open.
Can be seen that from above-mentioned process, one piece of filter plate near make position is always drawn in arm-tie action every time, each piece of filter plate thereafter is pulled again by this filter plate, and keep each piece of filter plate thereafter all to keep original aperture, often closing while one piece of filter plate on the right, also can pull open one piece of filter plate on the left side, in the middle of keeping, three pieces of filter plates are in open mode synchronizing moving, it is beneficial to coming off of filter cake, thus realizing the function of continuous plate-expanding.
In actual use, drawing-plate mechanism to take plate direction move through filter plate time, owing to plate pulling hook has certain elastic force, it can promote the filter plate pulled open toward take plate direction, and the filter plate that lastblock has been closed pulls open, and affects arm-tie effect.
For solving the problems referred to above, the present invention proposes further optimization method, adopts two set drawing-plate mechanism co-ordinations, and is overlapped drawing-plate mechanism cooperating by two, as shown in figure 13.
When the inside of first set drawing-plate mechanism and the drawing-plate mechanism of square shape layout, this is a set of, draw No. 2 filter plates and subsequent when 3, No. 4 filter plates move to No. 1 filter plate position, second set drawing-plate mechanism reversely moves toward No. 2 filter plates from No. 1 filter plate simultaneously, midway two set drawing-plate mechanism meets, second set drawing-plate mechanism is from process No. 2 filter plates, and continues to move to No. 3 filter plates.The drive motor of the present invention is VFC, the rotating forward arranged i.e. rotating speed rotationally clockwise is a bit larger tham the rotating speed of reversion, therefore, when No. 2 filter plates are pressed to No. 1 filter plate by first set arm-tie structure, what the second set drawing-plate mechanism also had been located in No. 3 filter plates takes Board position front.In the process, owing to the 2nd piece and the 3rd piece of filter plate are subject to the traction of first set drawing-plate mechanism, so when second overlaps drawing-plate mechanism by the 2nd, No. 3 filter plate, without influence on the aperture of No. 2 and No. 3 filter plate.When first set drawing-plate mechanism starts to return from No. 2 filter plate positions, the second set drawing-plate mechanism has pulled No. 3 filter plates and has moved to No. 2 filter plate direction.Then, when the second set drawing-plate mechanism moves No. 3 filter plate to make position, first set drawing-plate mechanism also has passed through No. 4 filter plate.So circulation, working in coordination of two set drawing-plate mechanisms, it is achieved that the filter plate of whole pressure filter is constantly being opened, the filter plate simultaneously having unsnatched filter cake constantly closes, it is achieved that the function of continuous plate-expanding.
The quantity of the filter plate of preferred embodiment is 80-90, all adopts connecting line to connect between filter plate, uses two set drawing-plate mechanism co-ordinations.Accompanying drawing only draws 10 filter plates, is for the ease of analysis principle and using method.
