Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a discharge device having 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 shown therein for the pyrolysis device 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 a 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 rent and gross remnants is not present in the known equipment.

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

Since residues are still falling on the rod screen, coarse residues are contaminated with fine residues when they reach the coarse residue outlet. The dwell time on the bar screen is not sufficient to shake the fine debris from the coarse debris from the bar screen, since new fine debris falls onto the coarse debris from above.

SUMMARY OF THE INVENTION

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

The object according to the invention is achieved in that the conveying device has a profiled distribution bottom, at the end of which, away from the mouth of the garbage manhole, a bar screen is formed, a conveyor exciter is assigned to the conveying device and in the case of a discharge for coarse residues.

With this discharge device, the advantage is that on the distribution bottom which is set in motion by the oscillator, the fine residues are shaken off the coarse residues without the other fine residues falling on the coarse residues. While coarse residues lie at elevated points of the profile, 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 conveying device through the bar screen further and fall into the coarse residue outlet.

To the outlet opening, resp. to the drain, other devices or vessels may be connected. Such a vessel does not need to be connected in a gas-tight manner, since the residue through the residue residue chamber is permanently present with carbonization residues.

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 output shaft to residues on the conveyor.

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 the relative movement of the conveying device to the debris outlet shaft.

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

For example, the distribution bottom has curved recesses at the transition to the bar screen. This preferably prevents coarse residues, which may include wire coils, from being heated at the end of the distribution bottom.

In another example, round dividing walls are provided between the fine residue outlet and the coarse residue outlet. This also has the advantage that no wire coils can be hooked.

For example, two separately operable oscillators are assigned to the conveying 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, there is a sealing plug of the carbonization residues in the residue outlet shaft, so that air oxygen access to the carbonization device is better than hitherto possible. In particular, the advantage is achieved that coarse residues are clearly better than previously separated from fine residues.

The disclosed combination of a profiled distribution bottom and a rod screen can also be used to separate or purify other substances.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 shows a dispenser housing 1 into which a discharge tube 2 of a carbonization drum 3, in which the waste is carbonized, opens out. This generates carbonization gas and carbonization residues which reach the housing L via the discharge tube 2. The rotatable discharge tube 2 is sealed to the housing 1 via a seal 4. The carbonization gas leaves the housing 1 via a discharge opening 5 located in the upper part thereof. and which is gas-tightly connected to a plant (not shown) for further processing of the carbonizing gas, for example a high-temperature combustion chamber. The solid carbonization residues fall down in the housing 1. From the lower outlet of the housing 1, which

It can be closed by the emergency slide 6, the outlet shaft for the residues 7 emerges. This 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 an apparatus for measuring the level of filling 8. The conveying device is controlled in such a way that in the outlet chamber 7 there is still a tight embankment of carbonation residues which prevents backflow of gases, especially air oxygen. drum 3.

The conveyor device consists of a profiled distributor base 9, which is located near the mouth of the outlet shaft for residues 7, and a rod screen 10 formed on the distributor base 9 in the transport direction, as well as an oscillator 11. and eccentric rollers, which are driven by an engine not shown here. Residual outlet shaft 7 is sealed with a flexible compensator 12 relative to the conveyor device. This makes it possible to ensure that the residue outlet chamber 7 is permanently gas-tightly closed by means of the residues. By vibrating the conveying device, coarse and fine residues are separated from one another on the distribution bottom 9 and at the same time conveyed further. The fine residues then pass through the rod sieve 10 and reach the outlet opening 13 of the rental residue which is located there. This outlet opening 13 can flow into the vessel, but also into a further processing device, e.g. a high temperature combustion chamber. The coarse debris is transported through the bar screen 10 to its end, from where it falls into the coarse debris 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 trapped.

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 at the tops of the profile 9a. By oscillating the distribution bottom 9, the fine residues adhering to the coarse residues are shaken off, leaving the coarse residues as clean as possible.

Figure 3 shows the transition of the distribution bottom 9 into the rod screen 10. In this transition region, the distribution bottom 9 has curved recesses 9b. This prevents coarse residues, such as wire coils, from hanging at the end of the distribution bottom 9.

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