The utility model is characterized in that the device includes a fixed plate, the upper side of the fixed plate is in an inner fovea shape, the inner fovea part of the fixed plate is provided with a movable plate in a cooperation manner, the fixed plate is provided with an elastic membrane, the lower surface of the elastic membrane and the inner fovea part of the fixed plate form a seal cavity, the fixed plate is provided with a through hole communicated with the inner cavity of the fixed plate, and the outer end face of the through hole is provided with a liquid supply joint. The utility model has advantages of ensuring the complete machine to be operated reliably, have good seal effect, simple structure and low power consumption.
Description
One, technical field
The utility model relates to a kind of Separation of Solid and Liquid field devices---vertical type blotter press, and particularly the filter plate of large tracts of land filter plate vertical type blotter press compresses and pressurizer.
Two, background technology
Vertical type blotter press is one of type of outbalance in the Separation of Solid and Liquid field devices, and the filter plate of existing vertical type blotter press holds out against with the pressurize mode three kinds of forms are generally arranged both at home and abroad:
First kind of mode, fast oil cylinder drives pressure strip filter plate is compacted to sealing state, and the two-way cylinder that is installed on the pressure strip drives the locking pin transverse movement, and locking pin is inserted in the locating hole on the column, during filtration, works the pressurize effect of locking; During discharging, locking pin is laterally pulled out, oil cylinder drive pressure strip is opened filter plate fast.Though this mode is energy-conservation, in actual use,, locking pin often occurs and insert the situation of not advancing and can not pull owing to reasons such as machining accuracy and buildups.
The second way, on the basis of first kind of mode, the retaining plate of filter press and between next piece filter plate a plurality of oil cylinders are set.Behind the locating hole on the locking pin insertion column, press on the heavy wool cylinder of bottom, hold out against filter plate; After the pressure release of heavy wool cylinder elder generation, again locking pin is laterally pulled out during discharging.This mode is complex structure not only, and stationary problem was difficult to solve when the heavy wool cylinder rose, and power consumption is big.
The third mode adopts single oil cylinder or heavy wool cylinder to hold out against pressurize.Adopt single oil cylinder to hold out against the filter press that pressurize only is used to be applicable to small size; Adopt the heavy wool cylinder to hold out against the pressurize that holds out against that pressurize is applicable to middle-size and small-size area.
Three, summary of the invention
The utility model is at above weak point, provide a kind of vertical type blotter press filter plate to hold out against pressurizer, during the work of this device, employing fluid injection in mechanism's cavity that flexible sheet, movable platen and fixed head are formed realizes that filter plate holds out against pressurize, has advantages such as power is little, the filter press manufacturing cost is few.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of vertical type blotter press filter plate holds out against pressurizer, the described pressurizer that holds out against comprises fixed head, the top of fixed head is inner concavity, cooperate with the fixed head female parts and to be provided with movable platen, the lower surface of movable platen and the female parts of fixed head form an annular seal space, fixed head is provided with a through hole that communicates with the fixed head inner chamber, and the outer face of through hole is provided with joint.
Above-mentioned vertical type blotter press filter plate holds out against pressurizer, is provided with a flexible sheet near movable platen limit inferior position in the described fixed head, and flexible sheet and fixed head female parts form an annular seal space.
Above-mentioned vertical type blotter press filter plate holds out against pressurizer, and described fixed head has whole and two kinds of structures of combination, is provided with the groove of direction in the chamber around the fixed head, and the flexible sheet edge is fixed in the groove.
Above-mentioned vertical type blotter press filter plate holds out against pressurizer, and the end of described movable platen is provided with the table top that matches with boss around the fixed head.
The utility model compared with prior art has the following advantages:
Originally hold out against pressurizer and replace existing locking pin to cooperate the mode of holding out against, saved oil cylinder with oil cylinder; Because movable platen is identical with the filter area of filter plate in this device, its work area is much larger than the area of oil cylinder, so it is low to hold out against the system works pressure of pressurizer, greatly reduce the power of complete machine, saved energy consumption, simultaneously because simple in structure, height dimension is little, has reduced device height effectively, has reduced manufacturing cost.Four,
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1
Fig. 3 is a scheme of installation of the present utility model.
Five, the specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
As shown in Figure 1 and Figure 2: a kind of vertical type blotter press filter plate holds out against pressurizer, this device adopts assembly type composite construction, the design of rectangular flat formula, it comprises rectangular-shaped fixed head 2, the upper surface of fixed head 2 is inner concavity, is provided with boss face all around, cooperate with the female parts of fixed head 2 to be provided with movable platen 4, the edge of movable platen 4 is provided with the table top that cooperates with the fixed head boss face; The bottom surface of movable platen 4 is smooth plane, and the bottom surface of movable platen, the interior section of fixed head form an annular seal space.
Described fixed head 2 has whole and two kinds of structures of combination, the bottom of integrally-built fixed head 2 inner concaves is provided with the through hole that communicates with annular seal space, be connected with joint 1 on the outer end fixed head 2 of through hole, fixed head 2 is a vertical plane with the mating surface of movable platen 4, the female parts inwall is provided with the groove towards annular seal space on the fixed head 2, be provided with flexible sheet 3 in the described groove, described flexible sheet 3 is near movable platen 4 limit inferior positions and be positioned at the lower end of movable platen 4.The platform of the fixed head 2 of combining structure is provided with a member, and this member inner concave at least overlaps with fixed head, is provided with flexible sheet between the two, and the top of member contacts cooperation with movable platen 4.
Concrete scheme of installation as shown in Figure 3, fixed head 2 is fixed on the vertical type blotter press retaining plate 5.When needing to filter, compression filter plates 6, spacer pin 7 with the top inserts in the spacing hole at top then, then by the sealing cavity liquid injecting of joint 1 to flexible sheet 3 and the formation of fixed head 2 female parts, flexible sheet 3 is jack-up movable platen 4 upwards, movable platen 4 holds out against filter plates, thereby plays the effect that holds out against pressurize.
This shows that the utility model adopts that fluid injection holds out against structure in the cavity, have to make complete machine reliable operation, good sealing effect, effect simple in structure, low in energy consumption.
