Definitions
- the invention relates to a device for conveying thick material with a delivery cylinder, with a feed side connected to the conveyor cylinder material feed chamber, with a discharge side connected to the delivery conveyor line, with a back through the material feed space and the delivery cylinder and herverschiebbaren delivery piston and with a arranged on the outlet side of the delivery cylinder or in the delivery line, adjustable between an open position and a blocking position blocking member.
- biogenic waste which as a rule contains not only organic constituents, but also considerable foreign substances.
- the foreign substances must be removed from the material stream.
- the path of comminution is chosen.
- hammer mills are used for the treatment of food waste. which are capable of crushing foreign matter, such as knife handles to a particle size of less than 10 mm.
- Such conditioned thick materials can indeed be transported by means of a slurry pump of the type specified.
- this has the disadvantage that the foreign substances are still contained in the material flow.
- substrate is moved from food waste, which is fed to a fermenter, and still contains shredded plastic packaging, cans, tubes, knives, forks as foreign substances.
- the organic substance is degraded there.
- the comminuted foreign matter present in the sludge must still be removed if the sludge is to be used as an organic nitrogen fertilizer. Without a separation, only disposal via incineration remains.
- the object of the invention is to improve the known device for conveying thick matter in such a way that the foreign substances are separated from the material stream before the actual processing stage for the useful substances.
- the inventive solution is based on the idea to develop a device that combines the properties of a sludge pump, a sieve and a press in itself.
- the delivery cylinder is perforated at least over part of its cylinder jacket.
- the device forms a press for the thick substances conveyed via the piston from the material feed space into the delivery cylinder when the blocking element is blocked.
- the perforated cylinder jacket forms a sieve, through which the liquid materials are conveyed under the action of the pressure built up by the press to the outside in a collecting shaft. The foreign substances are then pressed into the delivery line in the manner of a pump when the blocking element is then opened.
- an advantageous embodiment of the invention provides that the perforations of the cylinder jacket are formed by a breadboard.
- the perforations are arranged in a swept by the delivery piston when moving back and forth region of the cylinder jacket. It has proven to be advantageous if the opening cross-section of the perforations forming holes on the shell inside is smaller than on the outer shell side.
- the cylinder jacket of the delivery cylinder expediently consists of an internally hardened material.
- a preferred embodiment of the invention provides that in the region of the cylinder jacket, a slider is arranged, which is displaceable relative to the cylinder jacket between a closed position closing the perforations and an open position which releases them.
- the cylinder jacket is enclosed by a slide tube.
- the slide can be moved axially relative to the cylinder jacket.
- An advantageous embodiment of the invention provides that the cylinder jacket is perforated at most over half its length, while the slide has a closed lateral surface and is moved from the open to the closed position by half the cylinder jacket length.
- the slide it is also possible for the slide to have a grid of holes and closed spaces which is complementary to the hole pattern of the cylinder jacket. In this case it is possible that the slide between the open position and the closed position in the axial direction or in the circumferential direction by half the pitch of the hole pattern relative to the cylinder jacket is displaced or rotated. As a result, only a relatively small rotational or stroke movement of the slide results in comparison to the embodiment variant with half the cylinder length.
- a closing device which has a separate closing element, for example in the form of a stopper or a closing cone, for each perforation hole.
- a control unit for the coupled control of drive mechanisms for the piston, the Sperrorgan- and / or the slider movement is provided.
- the control member expediently forms a follow-up control for controlling the drive units of the piston, the blocking member and the slide.
- control unit responds to the travel signals generated by the piston triggering a closing movement of the blocking member, and / or if the control unit to output signals of a front of the blocking member in the delivery cylinder or in the delivery line arranged pressure sensor to trigger a Opening movement of the locking member responds.
- the slider may have a controllable via the control unit drive mechanism.
- the control unit for example, responsive to path signals of the delivery piston triggering an opening movement of the slide upon penetration of the delivery piston in the delivery cylinder, while it responds to a pressure signal of the pressure sensor triggering a closing movement of the slider when exceeding a predetermined pressure threshold.
- a cleaning device acting on the perforation holes with compressed air or pressurized water is expediently provided. Apart from that, the clogging of the perforation holes with filter cake is reliably avoided by the fact that the cylinder surface is automatically cleaned by the passing conveyor piston during each lifting operation.
- the delivery line opens into a recirculated to the material feed room, preferably designed as a bioreactor return path.
- a heating device which heats up the conveyed material can be arranged in the return path.
- a preferably meander-shaped extension section can be arranged in the return path.
- a pipeline leading to a processing station can be connected to the outside of the perforated cylinder jacket.
- the compressed through the perforations useful materials can be promoted via this pipeline to the processing station. This gives the pump the function of a two-phase pump.
- the device according to the invention is particularly suitable for carrying out a method for conveying mixtures of substances with different mixture components, of which at least one of the mixture constituents has a predominantly viscous consistency and at least one other mixture constituent has a predominantly particle-like solid consistency.
- the substance mixture is thereby pressed under construction of a pressure in a pressure chamber, wherein the mixture components with predominantly viscous consistency and the mixture components with predominantly particulate solid consistency are separated by the pressure built up in the pressure chamber to form different streams.
- the separation into different material streams preferably takes place in that the mixture constituents with predominantly viscous consistency are forced out of the pressure space into a first conveying path by discharge openings in a boundary wall, and that the mixture constituents predominantly have a particle-like solid consistency Opening a blocking member are urged from the pressure chamber in a second conveyor line.
- the opening of the blocking member is expediently triggered when a predetermined pressure limit is exceeded in the pressure chamber.
- the predominantly viscous mixture constituents are pressed through the perforations in the wall of the cylinder with the obturator closed, while the predominantly particle-like solid constituents of the mixture are displaced into a conveying line adjoining the cylinder after opening the closing organ.
- Fig. 1 is a diagram of a single-piston pump for processing
- Fig. 3 shows a meandering guided extension track for the
- the apparatus shown in the drawing is intended for processing and conveying of thick materials containing a liquid or pasty useful portion and solid foreign components.
- the device comprises in the manner of a piston pump one with a hydraulic piston 11 of a hydraulic cylinder 10 coupled plunger-like delivery piston 12, a feedable via a feed chute 14 with thick material material feed space 16, an input side to the material feed space 16 and output side connected to a feed line 18 conveyor cylinder 20, and a arranged on the output side of the delivery cylinder 20 slider-like blocking member 22 which is displaceable transversely to the delivery cylinder between a closed and an open position.
- the cylinder jacket 24 of the delivery cylinder 20 has formed as a perforated hole perforations 26, which open on the outside of the cylinder jacket 24 in a receiving shaft 28.
- the supply of material to the feed chute 14 takes place in the exemplary embodiment shown via a hopper 30 and a screw conveyor 32.
- the delivery piston 12 is in its retracted position in the hydraulic cylinder 10.
- the material supply space 16 is filled via the feed chute 14 to above the piston diameter, while the blocking member 22 is closed.
- the pressure increases up to a predetermined limit pressure Pzrenz, which can be set product-specifically.
- the limit pressure is selected, for example, so that packages located in the conveyed material burst and release their contents.
- the useful fraction pressed through the perforations 26 flows into the collecting chute 28 and is fed from there to a further processing stage.
- the movements of the delivery piston 12 and the blocking member 22 are controlled via a control unit 40 in the manner of a sequential control via suitable drive units coupled.
- a bioreactor reactor in the form of a hydrolysis stage may make sense.
- a recirculation path 34 recirculated to the loading shaft 14 is used, which depending on the desired residence distance. duration may also include a meandering guided extension 36.
- the perforated cylinder jacket 24 is surrounded by a tubular slider 38, which is displaceable relative to the cylinder jacket 24, between a closed position closing the perforations 26 and an open position which releases them.
- the cylinder jacket is perforated about half its length, while the slide has a closed lateral surface and is moved from the open to the closed position by half a cylinder barrel length.
- the slider 38 has a grid of solderers and closed intermediate spaces which is complementary to the hole pattern of the cylinder jacket. In this case, it is possible that the slide between the open position and the closed position in the axial direction or in the circumferential direction by half a pitch of the breadboard relative to the cylinder jacket is displaced or rotated. This results in a relatively small lifting or rotational movement of the slider 38 in comparison to the embodiment of FIG. 2a.
- the slider is also controlled via the control unit 40.
- the control unit 40 forms a sequence control for controlling the drive units of the delivery piston 12, the locking member 82 and the slider 38th
