which end between two fluids Shell housings is arranged.

The invention relates to a filter device, in particular to an automated filter device with a filter medium, which is between two fluid-carrying Sheath housings arranged and sealed on it is.

In the filter device according to the invention Filter medium between two fluid-carrying jacket housings held in place by an inflatable seal received in one of the housings. " Discharging air from this seal enables a clogged section of the filter media to be removed. and this is done either manually or automatically to be guided.

The use of an inflatable seal leads to several Benefits. E.g. sina large β and icobtspielige Z listening parts not necessary to operate the housing, to enable removal of the filter medium so that the device easily for use in common with

Filter aid materials can be set up. before all compressed gas is introduced into the upper case, when the filter media is clogged, to evacuate the upper case of fluid before the air is let out of the seal. Thus becomes a extremely simple and cheap, but effective filter device created.

. It is therefore a feature of the invention, a filter device for removing contaminants from a Provide fluid in which such contaminating constituents are finely distributed, two on top of each other arranged fluid-carrying housings are available, the essentially horizontal, mutually facing surfaces which are rotated to allow the flow of fluid therethrough, as well as a fluid outlet in one of the housings, and a Filtrate outlet in the other housing, marked by a filter medium, which between the recipients Sides of the housing is arranged an inflatable Gasket received by one of the housings, this gasket normally being inflated around the to seal one andex-facing surfaces to one another, wherein the filter medium is arranged between them, and from the

After the representation in Pig. 2, the upper housing 11 has impermeable, enclosing top and side walls. and a lower wall old a central opening 13, while the lower housing 12 has perforated surrounding side walls and a bottom wall and its upper wall is provided with an opening 14 and the lower housing 12 becomes a number in Filter medium supports 15 running in the longitudinal direction added

The opening 1 $ in the upper housing 11 is of one inflatable seal 16 surrounded by generally is hollow rectangular shape. The seal 16 is with a depending seal abutment 1? provided which protrudes towards the lower housing 12 and contacts the top of the same when the seal 16 passes through Gas, e.g. air, is inflated under pressure, which through a gas supply line 18 and a control valve 19 in the inside of the seal 16 is inserted *

In addition, according to FIG. 2, the housings 11 and 12 are supported by vertical side supports 20 which have inwardly projecting consoles or support arms 21 which hold the housings in relatively fixed positions perpendicularly spaced apart from one another. Two shafts running in the transverse direction are mounted in the side supports, on each of which pairs of sprockets 23 are fastened. These sprockets are held sideways voneinender a sufficient extent at a distance, so 'that they over the lower housing ¹ 12 may spread, and serve aufzu- sideways from each other suf-held distance chains 2>

take · These chains are identical and overlap the sprockets 23.

Bs is a number of transverse retaining brackets 27 attached to a filter medium 30, for example by rivets 28, and the brackets 27 connect, thus the chains and the filter medium 30. Additional transverse tie rods 29 span the chains 25. and their ends are attached to the chains and by means of rivets 28 to the leading, or naoheilendeη edges of the medium 30 attached. ™

The filter medium 30 is preferably a rectangular, fine-meshed sieve of a large size, which is the large one the openings 13, 14 in the housings 11, -12 exceeds. The SieD is in the Querrintung as well as in the Longitudinal direction over the openings 13, 14 in such a Mass before that the seal support 17 can capture the sieve. Thus, inflation of the seal 16 prints the fiI. termed ium in Diciatan ^ sexngrif f with the lower case 12, so that it surrounds the openings in the housing.

One of the side supports 20 is a limit switch LS 'ι added, the actuating arm lies in the path of movement of a stop 31, softer from the trailing one Tension rod 29 is added. A second limit switch LS 2 is at a distance from switch LS 1 on the path of movement the chain 25 arranged so that the stop 31 actuates the actuating arm of the limit switch LS 2, when a predetermined position of the chain has been reached. 909817/060 1

Inside the loop of the chain 25 there is' a. g9- J ^ fffieJtea tube 55 »which is received by one of the side supports 20 and projects in the transverse direction over the chain loop ; This drilling is closed for example by a control valve 54 and a line 55 attached to a source of un ter pressurized fluid, for example Dampfj ,, The holes or openings in the drilling 53 are directed downward to pressurized fluid at a lower drawing or to guide a collecting trough 36 to and into it, which is arranged outside the chain loop.

"Dirty" fluid, i.e. fluids in which contaminants are finely divided, is passed through a line 38, in which a control valve 59 is switched on is inserted into the upper housing 11. "Filtrate" fluid, i.e., fluid from which the contaminants have been removed is conveyed by means of a conduit 40 forwarded from the lower housing.

With the upper housing 11 is a pressure gauge or a . pressure sensitive controller 42 connected to respond to the fluid pressure therein by a line 43, and it is a pressurized gas line, e.g. Air line 44 with a control valve connected therein 4b is also connected to the upper housing 11. A reversible electric motor 47 is provided around one of the shafts 22 to drive and thereby scnickt the chains 25 by means of the Sprockets 23 forward or back.

The fluid that contains impurities enters upper housing 11 through conduit 38 and flows through the housing to lower opening 15.

The filtrate flows from the lower housing 12 through the line 4-0 to the outside.

The horizontal alignment of the filter medium 30 is extremely desirable for several reasons:

1.) The flow of the fluid takes place through the entire device in the sight of gravity}

2.) the horizontal top of the filter medium can be used to filter aids, e.g. Fuller's earth Or the like. To support it, and these filters help does not fall off the surface of the filter medium,

if a failure should occur in the fluid pressure.

3.) The device for removing 'the filter medium'

is greatly simplified, and the use of pressurized fluid to drain the upper housing 11 is also facilitated

During the flow of the fluid through the filter device, contaminants are deposited on the upper side of the filter medium or the filter aid, if such is used. When sufficient contaminants have accumulated on the surface of the filter medium 30 to significantly impede the flow of the fluid through the device , the pressure inside the upper housing 11 rises.

When this pressure has reached a predetermined maximum, the pressure control 42 is actuated to shut off the flow of fluid through the line 38 into the upper housing. At the same time, pressurized gas, such as air, is introduced through the line 45 into the upper housing and presses the fluid contained therein through the filter medium 30 down into the lower housing and through the .Ablassleitung 40 to the outside. When the upper housing 11 is emptied of contaminated fluid, the pressure located therein decreases and thereby gives a recognizable signal

The electric motor 4-7 is excited, to move the chains to the left by turning the sprockets counterclockwise (see Pig. 1) and thereby the filter medium from its position between the Remove housings.

The filter medium is pushed forward in such a mass that it around the left sprocket 23 in a relative reverse position is moved. If the filter medium moves counter-clockwise on this path, it moves under the cleaning tube 33, and a cleaning fluid such as steam flows under pressure "through the filter medium to remove the impurities flush from it down into the lower tub or drain container 36. If the filter medium is the Has traversed leg access pipe 33 completely, then the Switch LS 2 actuated by the stop 33, the motor 47 reversed and the filter medium clockwise into the in 1 to 3 position shown returned.
