Definitions
- the invention relates to a method for operating the air circuit and conveying the flow of material in the housing of a hammer crusher, which preferably shreds old material.
- the invention further relates to a housing of the hammer crusher for performing the method.
- hammer crushers are used for crushing scrap such as car bodies, so-called white goods and electronic scrap and the like.
- Such hammer breakers consist essentially of a housing with a good inlet, an upper and lower grating, a rotatably mounted rotor with tools such as hammers, which is driven at a relatively high peripheral speed.
- the rotor rotating in the housing gives the hammer crusher practically undesirable properties of a radial fan.
- the hammers act as blades that suck in the ambient air through part of the grate openings in the lower grate and blow them out through the grate openings in the upper grate. This effect creates an overpressure inside the housing, which attempts to balance itself against atmospheric pressure. Depending on the nature of the material to be shredded, this leads to considerable dust or environmental pollution in the vicinity of the hammer crusher.
- the disadvantageous blower effect for the operation of the hammer crusher should therefore be used, the housing should be designed accordingly and the effort required for dedusting systems should be reduced.
- the object is achieved in that the air flow and the material flow after passing through the upper classifying grate are guided practically vertically and offset and separately and downward to the housing wall down into the area of the lower classifying grate via a deflection hood and an adjoining channel . There, due to the prevailing negative pressure, the air portion is sucked back into the shredding chamber by passing through the lower classification grate, which creates a constant air circulation with an approximately equal amount of air.
- the air output to be generated can now be reduced by the proportion of the circulating air that is already circulating.
- This visual effect can be enhanced if the device provided under the area of the lower grating for further processing, sorting and / or conveying the shredded old material receives a step / cascade in which an additional fan with low power blows in air, making the lighter ones Components, such as the so-called shred the light fraction, even cleaner from the metal fraction, are fed to the dedusting duct.
- An additional effect can be achieved if, with the addition of finely atomized or atomized water during the comminution process, into the circulating air stream or into the housing by means of the water molecules or the large surface area of the water particles, the waste material, such as e.g. Car bodies in which a significant amount of heat is extracted from the shredding. This can reduce the risk of deflagrations and fires or the formation of burned hydrocarbons or so-called "blue smoke", as is often caused by the fuel residues or drawing oil residues present in the old material.
- the water mist is expediently injected through pipes into the housing above the rotor.
- the amount of water mist per unit of time can be regulated depending on the amount of material in the shredding area by measuring the current consumption of the drive motor for the rotor and on the other hand by measuring the temperature difference of the circulating air compared to the ambient air.
- Fig. 1 shows a section through a housing of a hammer crusher designed according to the invention without connection for a dedusting system and
- Fig. 2 shows a section through a housing designed according to the invention of a hammer crusher with dedusting shaft, which leads to a dedusting system, not shown.
- a hammer crusher consists of a housing 1 with a good inlet 3, a good outlet with upper classifying grate 4, a good outlet with lower classifying grate 5 and a rotor 2 mounted in tools 1 and equipped with tools.
- the rotor is with relatively high peripheral speed driven and crushed by the interaction of its tools, such as Hammers, with a fixed tool on the housing 1, e.g. Anvil on the upper classification grate 4 (Fig. 1), the old material, such as e.g. Scrap, car bodies, so-called white goods and also electronic scrap.
- the rotor 2 rotating in the housing 1 generates an air flow through the tools acting as blades, like a blower, which is sucked in from the ambient air through the openings of the lower classification grate 5 and blown out through the openings of the upper classification grate 4.
- the air flow and the material flows are shown symbolically in the drawings with arrows not shown.
- the invention now makes surprising use of the previously undesired blower effect in that the air flow is effectively used as circulating air and the air flow is deflected and vertically deflected by a previously unconventional deflection hood 8 together with the classified material flow of the shredded waste material passing through the upper classification grate 4 led below in a channel 6 delimited from the housing 1, this material flow in the area of the lower classification grate 5 is combined with the material flow classified here of the shredded waste material and, on the one hand, the air flow due to the negative pressure prevailing there in the circuit "lower grating 5 - shredding room 7 - upper grating 4 - channel 6 "and thus the above-described cycle and the material flows are repeated and, on the other hand, the combined material flow of the shredded waste material is guided to a device 11 for further processing, sorting and / or conveying the same.
- a dedusting air quantity reduced by the proportion of the air quantity generated by the rotor 2 as a result of the blower effect in the area of the lower classification grate 5 is switched on in an energetically favorable manner and reduces construction costs, and through a dedusting duct 9 guided in parallel to the duct 6 together with parts of a comminuted fraction, in this case the Shredder light fraction, removed to the dedusting system, not shown.
- a part of the de-dusting air acted upon can also be used for the removal of dust originating from fine particles of the old material to be abandoned in the area of the good inlet 3 to the dedusting system, which is indicated in FIG. 2.
- a particularly effective separation of the light fraction is achieved if the material flow brought together in the area of the lower classification grate 5 is acted upon by additional air by means of a fan 10 via a cascade-like step 12.
- the invention achieves an energy-efficient and environmentally friendly operation with reduced construction costs for the hammer crusher.
