Description
Technical field
The invention belongs to technical field of sludge deep dehydration, are related to a kind of deep dehydration device for sludge, more particularly to a kind of
The squeezer filter plate frame of axis constant force plunger case is covered with self- steering.
Background technology
Superelevation compression elasticity squeezer is a kind of equipment that material is carried out solid and liquid separation by pressure filtration, can be answered extensively
For municipal administration, petrochemical industry, light industry, chemical fibre, papermaking, pharmacy, leather, food, mineral products, metallurgy, electric power, building and agriculture, forestry, water conservancy etc.
The sewage treatment project of industry has unique superiority especially for the separation for gluing thin object.
The filter plate frame of traditional superelevation compression elasticity squeezer is four between fixing sheet frame (load sheet frame) and movable sheet frame
Several springs are arranged in week, reduce chamber space by compressed spring completely, to realize the extruding to sheet frame, reach dehydration purpose.
It is using the shortcomings that this structure:Sealing force is small when spring body initial compression, and the sealing force between sheet frame and sheet frame is insufficient, makes
Mud is sprayed at into easy when mud;Spring frangibility causes production to pause, and it is time-consuming and laborious to replace spring;Between sheet frame and sheet frame
It after guiding axis abrasion or after blocking, causes to misplace between sheet frame and sheet frame, mud is sprayed in seal failure.
At present there are also the filter plate frame of superelevation compression elasticity squeezer, compressed spring is replaced with plunger case, with realization pair
The extruding of sheet frame, reaches dehydration purpose.But it there is problems:(1) in expressing process, the fixing sheet frame of filter plate frame
(load sheet frame) and movable sheet frame must keeping parallelism movements.To ensure the fixing sheet frame (load sheet frame) and movable plate of filter plate frame
Frame moves in parallel, and several guide sleeves, axis typically is arranged between the fixing sheet frame of filter plate frame (load sheet frame) and movable sheet frame.
And these guide sleeves, axis corrosion-vulnerable are worn, and after guide sleeve, axis abrasion are a certain amount of, are oriented to failure, it is more in expressing process
A filter plate frame understands upward or flexural deformation to the left and right, causes spray mud.(2) it is machined with respectively on load sheet frame and movable sheet frame several
A counterbore, for installing the plunger case for covering axis with self- steering.Correspondence counterbore (plunger on processing load sheet frame and movable sheet frame
Cylinder mounting hole) when, center, axis will necessarily have error.This Working position error can give load sheet frame and movable plate
The assembly of frame brings very big difficulty, and can increase frictional resistance of the stainless steel column stopper rod in action process.
Invention content
It can slow down the abrasion of guide sleeve axis it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of, avoid filtering

Envelope).
The installation and application of the squeezer filter plate frame for covering axis constant force plunger case with self- steering of the present invention is as follows:It uses
When, the position of 20 guide sleeve axis was installed originally between the fixing sheet frame and movable sheet frame of every group of filter plate frame of squeezer,
Make the constant force plunger case that axis is covered with self- steering of the invention of installation 20 into.Also that is, in load sheet frame 51 (fixing sheet frame)
A concave hole (mounting hole) is dug in circumferential side frame at spacing intervals, on movable sheet frame 52 also correspondingly at spacing intervals
A corresponding concave hole (mounting hole) is dug, band self- steering set is installed in the mounting hole of load sheet frame 51 and movable sheet frame 52
The constant force plunger case of axis.Every specific installation method of constant force plunger case that axis is covered with self- steering is:First, by plunger case 60
61 cylinder of cylinder body is put into the mounting hole of load sheet frame 51, by the 61 outer ring method of cylinder body that fixing screws 59 are inserted into plunger case 60
It in the screw hole of blue screw hole and load sheet frame 51 and tightens, the cylinder body 61 of plunger case 60 is fixed on load sheet frame 51
On;Then, the cylinder bottom 62 of plunger case 60 is mounted in 61 cylinder of cylinder body;Later, the back segment of plunger rod 66 is mounted on cylinder body
Between 61 and cylinder bottom 62, by the mounting hole of the front end insertion activity sheet frame 52 of plunger rod 66, by compensating eccentric lantern ring automatically
53 compensation adjustment load sheet frames and movable sheet frame process the site error in hole;Finally, by 58 insertion activity sheet frame 52 of attachment screw
Screw hole and plunger rod 66 screw hole in and tighten, you can 66 front end of plunger rod and movable sheet frame 52 are fixedly connected on one
It rises.
The operating principle of the squeezer filter plate frame for covering axis constant force plunger case with self- steering of the present invention is as follows:
As shown in Fig. 4, Fig. 6, Figure 10, Figure 17, the pressure oil that is come out from hydraulic station fuel tank by technique oil duct general import and
General export (i.e. oil inlet and oil return pipe fitting 81), oil inlet and oil return channel (i.e. technique oil duct 80), technique oil inlet 82 enter plunger case 60 (into
Oil), a part enters the gap between cylinder body 61 and plunger rod 66, and from technique oil export 83, out (i.e. each plunger case shares
Into, drainback passage), into next plunger case 60;Another part enters the gap between 61 outer wall of cylinder body and load sheet frame 51,
The gap between cylinder body 61, the bottom of cylinder bottom 62 and load sheet frame 51 is entered back into, enters back into the cavity 63 inside cylinder bottom later, it
The cavity 65 (i.e. local oil inlet and oil return channel) for entering back into 66 back segment of plunger rod afterwards, plunger rod is pushed by the oil pressure in plunger case
66 stretch out, and transmit the force to movable sheet frame 52.
As shown in Fig. 4, Fig. 7, Figure 11, Figure 18, external force is acted on by movable sheet frame 52 on plunger rod 66, and plunger rod 66 moves back
Return, in plunger case oil by local oil inlet and oil return channel be discharged plunger case 60 (oil return), then by each plunger case share into, return
Oily channel and technique oil duct 80, oil return to next plunger case 60, finally by oil inlet and oil return pipe fitting 81, oil return to hydraulic station oil
