Technical field

BACKGROUND OF THE INVENTION The present invention relates to a discharge device with a housing into which a discharge tube of a carbonizing drum is discharged and from which a debris discharge shaft extends into a conveyor device which terminates in a drain.

BACKGROUND OF THE INVENTION

A discharge device of this type is known from DE 30 05 205 A1. The discharge device for the pyrolysis device shown therein is characterized in that the discharge vessel is still filled with carbonization residues during operation to form a gas-tight closure. The filling level measuring device checks the filling of the container. At the outlet of the vessel, the carbonization residues are discharged by the conveying device and fed to the outlet. Only so much residue is discharged through the conveying device that the filling of the housing does not fall below the position of the measuring device for measuring the level of filling.

Separation of residues into fine and coarse components is not present in the known apparatus.

Such a separation device is known from EP 0 086 488 A3. To this end, a rod screen is provided to which the oscillator is associated. The carbonization residues we want to sort fall on this rod screen. Below the rod screen there is an outlet for fine residues and at the end of the rod screen there is an outlet for coarse residues.

Because the rod sieve still reach the drain on the elongation time on the rod sieve fine coarse rod residues fall down, sieves shake off the residues, they are contaminated is not enough, from coarse coarse residues, fine to make residues when residues. shaking because new fine residues are falling from above on the coarse residue.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION The object of the present invention is to supplement the discharge device having a gas-tight closure with a separating device which separates the coarse and fine residues from one another, whilst cleaning the coarse residues from the adhering parts of the fine residues.

The object according to the invention is solved by the conveying device having a profiled dividing bottom, at the end of which is turned away from the mouth of the garbage outlet shaft, a rod screen is formed, an oscillator is assigned to the conveying device and the rod screen overlaps the garbage outlet opening. at the discharge for coarse residues.

With this discharge device, the advantage is achieved that on the bottom distributor which is actuated by the oscillator, the fine residues are shaken from the coarse residues, while the fine residues do not fall on the fine residues. While the coarse residues lie at the elevated points of the profile, the fine residues accumulate in the valleys of the profile. When the residues reach the shaped bar screen, the coarse residues are cleaned. The fine residues then fall through the rod screen into the fine residue outlet, and the cleaned coarse residues are then further transported by oscillating the conveyor device through the bar screen and dropping into the coarse residue outlet.

Additional devices or containers may be attached to the outlet or outlet. Such a vessel does not need to be connected to a gas-tight connection because a seal with carbonization residues is present at all times in the residue outlet shaft.

For example, the debris outlet shaft is bent toward the conveying device before it enters the conveying device. This ensures that residues are still sliding from the outlet shaft to the conveying equipment.

For example, the residual outlet shaft is sealed to the conveying device by means of a flexible compensator. This results in a seal between the two components which resists relative movement of the conveying device to the debris outlet shaft.

The profiled distribution bottom is, for example, of profiled sheet or profiled casting. For example, the distribution bottom has a sawtooth cross-section.

The distribution bottom has, for example, folded recesses at the passage to the bar screen. This preferably prevents coarse residues, which may include wire tangles, from being hooked at the end of the separating bottom.

In another example, round dividing walls are disposed between the debris outlet opening and the coarse residue outlet.

This also achieves the advantage that no wire tangles can be hooked.

For example, two separately actuatable oscillators are associated with the transport device. For example, the number of revolutions of the two oscillators may be different.

The dispensing device according to the invention also achieves the advantage that, with the use of a conveyor device equipped with an oscillator, a sealing plug of carbonization residues is present in the residue outlet shaft, so that air oxygen access to the carbonization device is better than previously possible. In particular, the advantage is achieved that the coarse residues are more clearly better than previously possible, separated from the fine residues.

The described combination of profiled distribution wire and rod screen can also be used for separating or cleaning other substances.

BRIEF DESCRIPTION OF THE DRAWINGS

The dispensing device according to the invention is explained in more detail with reference to the figures.

Fig. 1 shows the dispensing device of the figures.

Fig. 3 shows a front view of a profiled distribution bottom on which a rod screen is formed.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 shows a box 1 of the discharge device into which the discharge tube 2 of the carbonization drum 3, in which the waste is carbonized, opens. This results in carbonization gas and carbonization residues which enter the housing 1 via the discharge tube 2.

The rotatable discharge tube 2 is sealed with respect to the housing 1 via the seal 4. The carbonization gas leaves the housing 1 through a discharge opening 5, which is located in its upper part and which is connected to a gas-tight treatment device for further gas, for example high temperature. combustion chamber. Solid carbonization residues fall down in housing 1. From the lower outlet of the box 1, which can be closed by an emergency slider (L exits the outlet shaft for residues 7.

It opens into the conveyor and shortly before the mouth has a bend in the conveying direction of the conveyor. In the upper section of the outlet chamber 7 there is a device for measuring the level of filling 8. The conveying device is guided so that in the outlet chamber 7 there is still a tight filling of carbonization residues, which prevents backflow of gases, especially air oxygen into the carbonization drum. third

The conveyor device consists of a profiled distribution bottom 9, which is located near the mouth of the outlet shaft for residues

7, and a rod screen 10 formed on the divider bottom 9 in the transport direction as well as an oscillator 11. This may include springs for accommodating the conveying device and eccentric rollers, which are driven by an engine not shown here. Residual outlet shaft 7 is sealed against the conveyor device by a flexible compensator 12. The oscillator 11 can be operated. In this way, it is possible to ensure that the outlet residue chamber 7 is permanently gas-tightly closed by means of the residues. By vibrating the conveying device, coarse and fine residues are separated from each other on the divider bottom 9 and at the same time conveyed further. The fine residues then pass through the rod screen 10 and reach the fine residue outlet opening 13 therein. This outlet opening 13 may flow into the vessel, but also into a further processing device, for example a high temperature combustion chamber. The coarse residues are transported through the rod screen 10 to its end, from where they fall into the coarse residue outlet 14 located there. A container 15 can be connected to this outlet. Between the outlet opening 13 and the outlet 14 there are rounded dividing walls 16 on which no residues are retained.

Figure 2 shows a cross-section of a distribution bottom 9 having a sawtooth profile 9a. In the valleys of this profile 9a, fine residues accumulate, while the coarse residues lie on the tops of the profile 9a. By oscillating the distribution bottom 9, the fine residues that adhere to the coarse residues are shaken so that the coarse residues remain as clean as possible.

Figure 3 shows the passage of the distribution bottom 9 to the rod sieve W. In this passage region, the distribution bottom 9 has folded recesses 9b. This prevents coarse residues, such as wire tangles, from hanging at the end of the distributor bottom 9.

With the discharge device according to the invention, on the one hand, the return of the oxygen to the carbonating drum 3 is prevented, and on the other hand the coarse residues are almost completely separated from the fine residues. While the fine residues are generally further processed, the coarse residues consist of metal and glass parts which can also serve as raw materials.
