Definitions
- the invention relates to a filter press for press dewatering of sludge that is difficult to dewater
- DE 3744771 A1 describes a device for pressing out gaseous and / or liquid media from a batch of pourable or free-flowing material by compression to the solid mass of a press cake in a horizontal row of press chambers known.
- Each baling chamber has a pair of spacing parallel, vertical planes.
- at least one press wall with means for filtrate drainage is designed as a filter element, pressure bodies being arranged between the press chambers.
- at least one press wall is formed by a press element held on the pressure body and horizontally displaceable independently of the pressure body.
- US-A-3 073 238 describes a hydraulic press which has two series of multiple press chambers with filter plates for high production.
- a multi-pot press for de-oiling cocoa is known, with press heads and pot pistons connected with sliding members are provided, the closing direction of which is opposite the pressing direction is and in the impression piston-cylinder units with piston rods formed from impression rods for opening the press and for ejecting the press cake are angeord net.
- the pressure cylinders are arranged axially displaceably in the crosshead of the press and are firmly connected to the press pot which is furthest away from the plunger.
- the well-known chamber filter presses are cumbersome in their construction and therefore prone to failure.
- the finished pressed filter cake still has a relatively high water content, because they are operated with a low filtration pressure of maximum 25 bar.
- the invention has for its object to provide a filter press of the type mentioned in such a way that it is robust and simple, therefore less prone to failure and is also operated with such a high pressure that the pressed filter cake has a relatively low water content.
- each sliding ring is optionally provided with a separate or a common hydraulic drive with which to close the associated press chamber, to keep the closed state and to open the press chamber,
- each sliding ring has at least one filling opening
- each sliding ring is adjustable in the axial direction, so that the chamber volume can be changed.
- a high-pressure filter of the type mentioned in the introduction, which fulfills the above-mentioned inventive task.
- the high-pressure filter can be designed so that a press cylinder is provided as a common drive for al le press body, which is arranged on one plate of the frame.
- the cylinder of the displacement cylinder is expediently arranged on a bearing block of the pressing body and the piston rod on a bearing block of the displacement ring.
- the press walls are provided with a number of filtrate openings with filter cloths and filter material in the form of a filter cloth is provided within the press chambers in front of the filter openings.
- At least one filling opening is provided in the sliding ring for filling the open press chamber.
- Fig. 1 a central longitudinal section through the high-pressure press filter designed according to the invention in the filling position
- Fig. 3 the same high-pressure press filter in the ejection position with the plunger in the starting position.
- the drawing shows three operating states of the high-pressure press filter designed according to the invention, namely in FIG. 1 the filling of the high-pressure press filter with sludge to be dewatered, in FIG. 2 the pressing of the sludge and in FIG. 3 the dropping of the dewatered filter cake.
- the high-pressure filter has according to Figure 1 two spaced plates 1, 2, which are connected to each other via several tie rods 3, 4 and held at the required distance from each other.
- a press cylinder 5 is arranged on the plate 1, the piston rod 6 of which has a press piston 7 at its cylinder-side end and a piston plate 8 at its opposite end.
- the Piston plate lies on an annular surface 9 against a filter plate 10.
- a filtrate chamber 1 2 is provided, which has a filtrate outlet 13 with a bore 13a, which extends in the direction of the Arrow 14 can empty the filtrate chamber 12.
- a counter plate 19 is provided, which likewise has filtrate openings 20 and a filter cloth and is otherwise designed like the inner region of the filter plate 10.
- the counter filter plate 19 is followed by a cylindrical housing part 21 which, on the side opposite the counter filter plate 19, has a filter plate 22 which contains the filtrate openings 23 and a filter cloth and is otherwise designed in the same way as the counter filter plate 19.
- An abutment 24 is provided on the cylindrical housing part 21.
- a filtrate drain 25 is provided on the housing part 21, which has a bore 26 through which the filtrate can flow outward from the filtrate chamber 27 in the direction of arrow 28.
- a further counter filter plate 29 with filtrate openings 30 and a filter cloth is provided, which is connected to the plate 2 via a cylindrical housing part 31, a hole 32 in the plate 2 for the filtrate to flow out of the filtrate chamber 33 is provided in the direction of arrow 34 to the outside.
- a circumferential seal 35 is provided on the filter plate 22, as on the filter plate 10.
- circumferential seals 36 and 37 are also provided on counter filter plate 19 and counter filter plate 29.
- a press chamber 38 filled with sludge to be dewatered is formed, which otherwise has the same dimensions and the same design as the press chamber 16.
- the pressing chamber 1 6 is closed all around with a sliding ring 39, through which the pressing chamber 16 is closed by means of the seals 18, 36.
- a driver 40 is arranged on the sliding ring 29 and is connected to a piston rod 41.
- the piston rod 41 interacts with a displacement cylinder 42 which is fastened to the abutment 24.
- a Schlammei inlet 43 is provided with a bore 44 through which sludge to be dewatered in the direction of arrow 45 is filled into the pressing chamber 16. The same applies to the press chamber 38.
- the mode of operation of the high-pressure press filter designed according to the invention is as follows:
- filtrate flows from the pressing chamber 16, 38 through the filtrate openings 15, 20, 23, 30 and a filter cloth into the filtrate chambers 12, 27, 33 and from these filtrate chambers 12, 27 , 33 through the bores 13a, 26 and 34 of the filtrate outlets 13, 25 and the plate 2 in the direction of the arrows 14,28,34 to the outside.
