- Such a device can in particular used in wastewater treatment plants is also advantageous applicable to other areas of technology, for example in the textile industry, the plastics industry, in slaughterhouses and the like, and always when a material to be separated in more or less solid form from a liquid, in particular Water to be taken out and conditions can occur,
- Such a device for removing material to be separated from a liquid flowing in a channel necessarily points also a separator, which has a separating surface has, which flows through the liquid to be cleaned becomes.
- this separator is designed it does not matter in the present context. It can therefore be of any design.
- the problem on which the present invention is based is the following.
- the liquid flowing in the channel becomes all As a rule, especially in sewage treatment plants, a temperature of 10 ° C have so that there is no risk of freezing.
- the above-mentioned device also has parts, in particular the upward sloping or vertical conveying Screw conveyor, especially outdoors and in Winter operation can also be exposed to sub-zero temperatures. In order to there is a risk of freezing here. This will still be thereby increased that the screw conveyor usually is not operated continuously, but discontinuously, the time intervals in which the material to be separated is in the range the screw conveyor rests, also become relatively large can.
- FR-A-2 642 326 describes a device of the type described at the beginning Kind known, which is preferably used for dewaxing Bird feathers is used. It is an upward slant and screw conveyor device leading to a discharge point provided that a housing, a shaft and a conveyor spiral having. There is a between the housing and the conveyor spiral Filter wall, e.g. B. in the form of a sieve.
- the Liquid becomes the device at a temperature of about 100 ° C and must be cooled in the Device are protected. This happens through an outside Sheathing the device with an insulating wall.
- the Insulating wall is at a distance from the housing of the screw conveyor intended.
- the space thus formed can for example heated with steam. Alternatively, it is Arrangement of an electrical resistance heater at this point possible.
- the heating device is used to heat the liquid Waxes to prevent it from solidifying.
- the heater has a heat generator in the form of a heating cable, which is attached to the outside of the housing of the screw conveyor is.
- the heating cable extends over essential Areas of the axial length of the housing and over its circumference.
- the heat generator is then covered by an insulating layer, which the heat output of the heat generator to the outside in reasonable Should keep boundaries.
- the insulation is replaced by a second Protected housing, which includes the insulation. So that is the structural effort for the insulation and the additional, serving as a casing considerably. The effective one part of the heat acting on the separated material is due to the losses occurring unsatisfactory.
- the invention is therefore based on the object of a device the type described at the outset, in which the in the Energy released from heat generators is used more economically.
- this is the case with a device of the beginning described type achieved in that the shaft at least in their area facing the discharge point is designed as a hollow shaft is, and that the heat generator of the heater in the Hollow shaft is arranged.
- the invention is based on the idea that the heat generator does not more outside, i.e. outside the housing of the screw conveyor, to arrange, but as it were in the center or in the Axis of the shaft of the screw conveyor.
- the shaft is designed as a hollow shaft, which is simple can be done by using a tube as a shaft, on the outer circumference of the conveyor spiral is arranged.
- the interior thus formed represents the arrangement of the heat generator of the heating device.
- an electric heat generator application so that electrical energy in a simple manner through the hollow shaft Heat generator can be fed.
- the heat generator can be arranged stationary in the hollow shaft be.
- the heat generator can in particular take the form of a rod. It is possible to use the stationary heat generator one or more bearings opposite the rotating hollow shaft to support.
- the heat generator in the hollow shaft is arranged co-rotating and that for the supply electrical Energy is provided to the heat generator by a slip ring body is.
- the energy supply takes the form of electrical energy thereby via a slip ring body which is arranged on the hollow shaft is.
- This heat transfer medium serves to couple the surface of the heat generator with the inner surface of the hollow shaft and To this extent, it favors heat transfer.
- the heat transfer medium can be a liquid be. But also the use of an easily meltable salt is possible. The advantage is then used that the amount of heat, which is required to change the physical state, can be used for storage purposes, so that the temperature of the heat transfer medium can remain constant.
- a motor Wave for the purpose of supplying electrical energy in particular the heat generator is pierced.
- the energy is supplied then under through the pierced shaft of the motor direct connection to the hollow shaft of the screw conveyor. This applies not only to the supply of electrical energy, but also, for example, when one of the warming serving liquid by means of a pump via a pipeline is sent through the hollow shaft.
- the housing of the screw conveyor can be insulated be surrounded. This will result in radiation and convection losses reduced the housing of the screw conveyor.
- the screw conveyor can be in front of the discharge point have openwork drainage housing.
- the drainage housing can be made of insulating material, in particular Polyurethane.
- Here is preferably a compacting zone formed for the material to be separated and the liquid can through the openings in the channel.
- a device 1 is shown, which is essentially on the one hand a separator 2 and a Screw conveyor 3 comprises.
- the device 1 is in a channel 4 with its common axis 5 inclined built in, so that in particular part of the Separation device 2 is located below the water level 6, while the screw conveyor 3 at least with their upper part is arranged above the water level 6 and out the channel 4 leads upwards.
- the screw conveyor 3 has a hollow shaft 7, a Conveyor coil 8 and a housing 9, which the conveyor coil 8 surrounds tubular.
- a Motor 10 placed on the drive of the hollow shaft 7 with a spiral conveyor 8 serves.
- a discharge point 11 is formed, for example as Discharge chute the discharge of the material to be separated into a container enables.
- a compacting zone formed for the material to be separated 15 in the area of which provided with openings drainage housing 19 is.
- the drainage housing 19 consists of insulating Material, especially polyurethane.
- the screw conveyor 3 is at least in its upper one Area in which you are exposed to the influence of minus temperatures, especially in winter, may be exposed to a Provide heating device, the essential components of which Interior 12 of the hollow shaft 7 are arranged.
- Fig. 2 leaves one Recognize heat generator 13 which is rod-shaped. Also the arrangement of heating cables or the like can be possible here.
- the electrical energy as a rule, is supplied by the hollow shaft 7 from its upper end.
- Fig. 3 shows the end of the motor 10 above.
- the shaft of the motor 10 is also hollow, so pierced.
- a slip ring body 14 is used to feed the electrical energy for the Case that the heat generator 13 rotating in the interior 12 of the Hollow shaft 7 is arranged. But it is also possible that Arrange energy generator 13 stationary, so that the The supply of energy is provided to be stationary.
- Fig. 2 shows how the material to be separated 15 on the Conveyor spiral 8, partially resting on the wall of the housing 9 can be deposited, at least for the times when the Screw conveyor 3 is not driven. As is well known there is an intermittent drive with more or less large downtimes.
- the housing 9 of the screw conveyor 3 may be surrounded by insulation 16, which is appropriate is protected by a panel 17.
- Fig. 2 shows that the interior 12 of the hollow shaft 7 with a heat transfer medium 18 completely or partially filled can be, which surrounds the heat generator 13 and for one provides better heat transfer to the hollow shaft 7.
- the heat transfer medium can be a liquid, but also a latent heat storage be, for example a salt, which is comparatively low heating temperature in the liquid state transforms.
