Definitions
- the invention relates to a plant for screening a fraction of small grain sizes from one by means of a Crusher or similar comminuted goods according to the generic term of claim 1.
- the recycling material should be one desired grain line so that the individual Fractions for desired uses, for example in road construction.
- a drum screen which is used for the separation from one mixture of different materials with high Moisture level serves.
- knives, nozzles and brushes are provided, which when rotating the Make sure the holes in the sieve are clean.
- a drum screen has become known to be provided for metallic powder in the range of 0.1 mm Grain size and smaller.
- a nozzle plate attached to a supply line for a Fluid is connected.
- a screening drum for e.g. fibrous compost A compressed air nozzle tube in the upper area of the sieve drum arrange that by a compressor with compressed air is supplied.
- the nozzle tube serves the sieve drum of fiber parts that are in the sieve drum have fixed.
- the invention has for its object a system for Sifting a fraction of smaller grain sizes out of one material crushed by means of a crusher or the like to create, in which the throughput can be increased.
- a compressed gas used the exhaust gas of a diesel engine is used as a compressed gas used the exhaust gas of a diesel engine.
- Crushing plants usually use a generator that generates the electricity generated for the electric motor that drives the crusher.
- a diesel engine is used to drive the generator.
- the Exhaust gas from a diesel engine has a temperature of over 500 ° C and is also under a sufficiently high pressure so that it can be used to supply the flow nozzle. In this way it is possible to use a large part of the energy loss of the diesel engine in a screening plant for this use, increase the throughput and a trouble-free To ensure operation.
- soot particle filter To prevent contamination of the screenings from soot particles prevent it, it is recommended to install a soot particle filter, into which the unpurified exhaust gas is introduced. It is possible to use a known filter with a degree of particle separation get up to 95%.
- the flow nozzle adjustable via an adjustment drive is to change the height of the entry area of the flow into the sieve drum.
- the flow nozzle can after a Another embodiment of the invention as an opening in a Plate be formed with the adjusting device is coupled.
- the plate extends approximately tangentially to the screening drum and relocated during an adjustment the relative position of the nozzle opening and thus also the position with respect to the drum in which the gas flow into the sieve drum entry.
- the location of the flow nozzle can be below other dependent on the pressure of the Gas. Therefore, an embodiment of the invention provides that a control device for the adjustment device is provided as well as a pressure sensor in front of the flow nozzle, which measures the pressure of the gas, the adjusting device the flow nozzle is adjusted depending on the pressure.
- the fluid entered must escape from the screen drum again.
- the air outlet can be almost extend the entire face, being careful must be that the radially outer area free remains for the discharge of the coarser material.
- an apron or the like may be provided by the material is pushed aside so that as little as possible Unfiltered gas is released.
- the air outlet is otherwise provided with a filter, for example a filter mat, which prevents very fine particles spread outward in dust.
- For suppression water can also be used to form dust be, that by means of spray nozzles on the emerging coarser Material is sprayed.
- Another outlet can be through at least one in the top Area of the housing provided connection, which is also provided with a filter device.
- the filtered gas can be connected to the Feed line for the flow nozzle to be connected to the reuse escaping gas.
- In the return line can be a heater according to an embodiment of the invention be provided which the recirculated gas to the temperature of the gas in the supply line.
- the wall of the housing for the sieve drum with is provided with thermal insulation.
- a sieve drum 10 is inclined somewhat to the horizontal Axis in a housing, as indicated at 12 in FIG. 1 is rotatably mounted. In the present case three drives 14 arranged in the upper area.
- the material inlet is indicated by an arrow 16. He is itself at the higher end of the screening drum 10.
- the Material outlet for the screenings is marked with the arrow 18.
- the screenings should be in the grain size range 0 to 4.
- the unscreened good is made removed from the drum 10 at 20.
- the sieve drum At the front end is the sieve drum with a circumferential direction to provide extending outlet for this good.
- a gas outlet 22 for example in the form of lamellas, to which a filter 24, for example in the form of a filter mat is.
- the function of the gas outlet 22 is shown below still explained.
- the housing 12 which, moreover, with thermal insulation is provided, has an outlet 26 in the lower region for the screenings, which falls on a take-off belt 28, the individual is not shown.
- Slightly above the Outlet 26 on the upwardly moving part of the screening drum 10 that rotates clockwise is one Plate 30 arranged a relatively close distance to the drum 10 and in the direction of the double arrow 32 is adjustably mounted in the housing 12.
- the Plate 30 has a nozzle opening 34.
- the plate 30 is located at the end of an expanding line 36, with the exhaust of a diesel engine (not shown) connected is.
- the diesel engine is part of it, for example of a generator that supplies energy for ensures an electric motor that one not shown Drives crusher. It also supplies the electric motor or the motors for driving the screening drum 10.
- a return line 50 into line 36 is introduced.
- one Heater 52 provided to the recycle gas bring it back to the temperature of the exhaust gas.
- the Filter device 48 separated particles pass over a shaft 54 to a screw conveyor 56, which fine screened material is transported to take-off belt 28.
- the plate 30 is by means of an adjusting cylinder 58 adjustable in the direction of the double arrow 32 depending on the Operating conditions, i.e. Condition of the sieved Good and the pressure on line 36.
- a pressure transmitter (not shown) can be provided which connected to a control device, also not shown which actuates the adjusting cylinder 58 in dependence from the measured pressure.
- An adjustment can be made analogously of the circularly bent baffle 42 made become.
