Detailed description of the invention
Fig. 1 shows a kind of filter press in the prior art.
Fig. 2 shows another filter press in the prior art.
Fig. 3 shows filter press according to an embodiment of the invention.
Specific embodiment
Use feelings of the present inventor to the various filter presses (filter press including type shown in Fig. 1 and Fig. 2) of the prior art
Condition and design scheme have made intensive studies, and have found following problem by the research.
To the filter press of second of type as shown in Figure 2, one problem is: (filtering when designing larger filter area
Plate is more) filter press when, the length of connecting rod 201 and four filter press girders will be lengthened accordingly.Connecting rod 201 is because of its use
The requirement of function is needed with high-intensitive alloy steel material and is made through Overheating Treatment.And the length of connecting rod 201 is bigger, then needs
The process equipments such as the Equipment for Heating Processing including Large-scale Heater wanted and metal cutting are also bigger, lead to filter press manufacturing cost
It sharply increases.In addition, connecting rod 201 natively needs to have very high intensity, and with the lengthening of connecting rod 201, connecting rod 201 is because certainly
Sag bent problem caused by body gravity will become more serious, this inevitable requirement is set by increasing connecting rod diameter to increase it
Intensity is counted, to further increase manufacturing cost, and the negative consequence of connecting rod sag bent is still difficult to eliminate.
The increasing of filter area (i.e. filter plate quantity), is on the one hand the cause for leading to above situation, is again on the other hand to work as
One important need of preceding filter press market application.Because one it is well-known conventional wisdom is that, when realizing identical yield, one
The large-scale filter press of platform operation at full capacity, than complete same yield two or more more small-sized filter presses integrated operation at
This is much lower.Especially under the overall situation of current worldwide sluggish economy, influence of the scale cost benefit to operation success or failure is more
Exacerbation is wanted.
The present invention is described below in conjunction with drawings and examples.
And to the filter press of the first seed type as shown in Figure 1, although the above-mentioned problem related with connecting rod is not present, and
Seem the requirement for being also easy to meet equipment enlarging, but in place of it also has the wretched insufficiency of oneself, problem first is that in main oil
During the promotion movable plate 105 of cylinder piston rod 103 is with " holding out against " filter plate 106, it is easy to go out on movable plate 105 and filter plate 106
Existing cross component force, and with the increasing of filter plate quantity (filter area), there is the case where cross component force also more seriously, so that making
Lateral bending deformation occurs at filter press girder 107, and then makes movable plate, filter plate suspension idler wheel 104 " derailing ", filter chamber is caused to seal
It closes not tight, or even will affect the safe operation of filter press.
And the problem of " cross component force " that occurs is easy in " holding out against " formula scheme, in " holding " formula side as shown in Figure 2
It is then substantially not present in case.
It can be seen that being faced with some predicaments here, it may be assumed that following whole benefits can not be obtained simultaneously, it may be assumed that
1) the manufacturing cost advantage of large-scale filter press；2) it is more advantageous to the filter plate quantity (mistake of filter press
Filtering surface product) flexible setting；
3) it avoids the problem that or reduces above-mentioned " cross component force "；
4) avoid or reduce the connecting rod lengthening all problems of bring；
5) size that equipment is minimized in the case that filter plate quantity (filter area namely yield) is constant is being kept, especially
It is longitudinal size (along the size of filter plate orientation).
Based on the consideration to above-mentioned factor etc., present inventors have proposed filter press schemes according to the present invention, are passed with overcoming
The above-mentioned deficiency of system filter press.
As shown in figure 3, filter press according to an embodiment of the invention includes that four horizontal oil cylinders 305 are (only aobvious in Fig. 3
Two oil cylinders 305 in the side of filter press are shown)；.Oil cylinder 305 takes horizontal installation form, the piston rod 306 of oil cylinder 305
Flexible drive movable plate 308 movement.When piston rod 306 retracts, oil cylinder 305 embraces filter plate 304 " by movable plate 308
Tightly ", so that the filter chamber formed between filter plate 304 be made to close.According to one embodiment of present invention, oil cylinder 305 passes through cylinder body
Pin shaft 311 is respectively hinged on oil cylinder seat 301；Oil cylinder seat 301 is welded on girder 303 and lower girder 312；Piston rod 306
Then hinged by piston rod pin shaft 310 and movable plate 308, fixed plate 302 and portal frame 309 pass through upper girder 303 and lower girder
312 are connected to become a general frame.
Obviously, the scheme of four horizontal oil cylinders 305 is easy to be generalized to the scheme of multiple horizontal oil cylinders 305, as long as these are sleeping
Formula oil cylinder 305 is symmetrically arranged.The scheme of this multiple horizontal oil cylinders, it is clear that also belong to the scope of the present invention.
In the filter press according to the present invention, the welding position (edge of oil cylinder seat 301 and upper girder 303 or lower girder 312
The position of filter plate orientation) can flexibly set, thus can be made by suitably selecting the position of the oil cylinder seat 301
The oil cylinder of same model adapts to the filter press of different filter plate quantity, i.e., in the case where not changing oil cylinder model, by changing oil
The link position of cylinder and upper girder and lower girder, so that it may produce the filter press with different filter areas (filter plate sum)；
Can also by changing length of oil cylinder, when designing and manufacturing for " grouping open " filter chamber per " group " in the different pressure of filter plate quantity
Filter.For example, general every group is that 8 filter plates may be designed to every group of 6 filter plates or 10 filter plates after changing length of oil cylinder.
The invention has the advantages that
1) since the filter chamber for using " holding " filter plate is closed scheme, lateral force will not be generated and causes filter press girder curved
Song deformation, ensure that the airtightness of filter chamber and the safe operation of equipment；
2) the horizontal installation of oil cylinder, the direct sliding movable plate movement of cylinder piston rod, eliminates aforementioned second of traditional structure
Middle cost high " set square (crank) " and " connecting rod "；
3) position that oil cylinder is fixedly connected with girder can flexibly be set, thus the oil cylinder of same model can be suitable for not
The filter press of same filter area (filter plate quantity),；
4) since the filter press of larger (filter area/filter plate quantity is bigger), and cost 1), 2) He 3), can be manufactured
It is lower, it runs more reliable, safer；
5) overall dimensions of filter press, especially longitudinal size are reduced as much as possible.
