Definitions
- the invention relates, on the one hand, to a method for measuring the weight of coke and, on the other hand, to a coke quenching car.
- a coal filling truck is moved on the furnace roof of the kiln chambers of a coke oven battery.
- the coal filling truck picks up coal from a coal tower and transports it to the furnace chambers of the coke oven battery.
- the charcoal is filled there by filling holes in the furnace chambers.
- the forming cones are leveled with a leveling bar.
- the coal is converted zone by zone from the chamber walls to the center of the chamber after filling into the two-sided heated furnace chamber to coke.
- a coke cake is formed in the oven chamber, wherein for ejecting the coke cake from the oven chamber, a push rod of a push-out carriage passes through the oven chamber and pushes the coke over the coke cake guide carriage or a coke transfer carriage into a fire truck.
- the glowing coke is driven with the fire truck under a quenching tower and extinguished there with water so that it does not burn in the air.
- the emptied coke oven is immediately charged again with new coal.
- the extinguished coke slides out of the fire truck onto a coke ramp, where it evaporates and then passes through a conveyor belt into the coke oven.
- the conveyor belt has a belt scale, which is designed topersbe mood of the deleted coke.
- the measured weight of the quenched coke is used to calculate the yield that can be achieved during a coking process and is therefore a prerequisite for calculating the costs that must be estimated for the production of coke in the coke oven.
- a disadvantage of the known method for measuring the weight of coke by means of a belt weigher during the conveying process of the coke in the Kokssieberei is that the total weight of the coke is weighed in the extinguished state, are co-weighed with extinguishing water, which is still in the after evaporation of the coke Coke and are used falsification of the results can lead.
- the weight of coke residues on the belt scale from previous coking processes is also included in the weight determination. It is therefore not possible to indicate the yield of a coking process with high accuracy. This has a negative impact on the cost calculation as uncertainty.
- the object of the present invention is to provide a method for measuring the weight of coke and a coke quenching truck, with which an exact measurement of the weight of coke is possible.
- the above object is achieved in a first alternative in a method for measuring the weight of coke essentially in that the measurement is carried out in the uneröschten state of the coke, preferably immediately after or during the ejection of the coke from a furnace chamber of a coke oven.
- the invention is therefore based on the basic idea to carry out the measurement of the weight of coke before the coke is cooled with the extinguishing water, and thus ultimately immediately after expressing.
- the weight measurement before the extinguishing process is rather that, in determining the yield of coke production, there is no distortion of the results due to extinguishing water components in the coking chambers. This makes it possible to carry out the calculation of the costs associated with the production of coke in a coke oven with higher accuracy than was previously possible.
- the measurement of the weight takes place on or in a coke quenching car.
- the coke in the unerased state it is also possible to measure the weight of the coke on or in the coke quenching car, preferably immediately after the extinguishing process.
- the weight of the uncapped coke can be determined.
- the coke is transferred to a coke quenching truck and that the weight of Kokslöschwagens is measured with a stationary track scale.
- the track scale may have a track portion which is coupled to a corresponding measuring device.
- the measuring device may comprise weighing cells, which are arranged below the track section.
- the track section has a length which corresponds at least to the length of the Kokslöschwagens.
- the weight measurement of Kokslöschwagens takes place in the extinguishing tower or before the retraction of Kokslöschwagens in the extinguishing tower.
- a weight measurement of Kokslöschwagens preferably takes place at a standstill of Kokslöschwagens, as soon as it is ascended to the track scale.
- the coke quenching truck has a measuring device on or in the coke quenching carriage, which is designed to measure the weight of coke in the coke quenching truck.
- the measuring device can have at least one load cell and / or at least one strain gauge as the measurement receiving means.
- the weight measurement on or in Kokslöschwagen also has the advantage that the implementation of the weight measurement with low design complexity and with high reliability is possible.
- the Meßingstoff is provided between the substructure and the coke box of Kokslöschwagens arranged thereon to measure the weight of the coke box in the tare weight measurement.
- the Meßingstoff is provided between the substructure and the coke box of Kokslöschwagens arranged thereon to measure the weight of the coke box in the tare weight measurement.
- the Total weight of the fire truck detected.
- only the weight of the coke box is measured.
- both alternative embodiments of the invention permit the measurement of the weight to be carried out immediately after the coke has been introduced into the coke quenching car. Here it is important that the weight of the coke is measured before the deletion process begins.
- a weight measurement can be carried out on or in the empty coke quenching truck.
- This blank weight measurement of Kokslöschwagens serves to rule out the falsification of the measurement results in the weight measurement of the coke by remaining on the Kokslöschwagen coke residues of a previous deletion process.
- a taring is provided before each measurement, wherein the invention basically of course also allows that only a tare measurement of the coke box takes place.
- the taring can be done at standstill of the Kokslöschwagens and arrangement of Kokslöschwagens in the Koksüberleit ein to exclude parasitic effects that may result from the movement of Kokslöschwagens.
- the measurement is then automatically carried out, wherein a measurement signal can signal the time at which the coke is completely expressed from the furnace chamber , On the basis of this signal, a weight measurement can take place when the coke slag is at rest as a full-weight measurement, in particular in the coke transfer position.
- the weight of the coke in the Kokslöschwagens can then be determined automatically from the tare weight measured in the tare and the measured full weight.
- the last-mentioned features relate to the weight measurement of the coke quencher, it is of course also possible for the weight of the coke container to be determined in the empty state during the taring and subsequently in the loaded state becomes.
- a position detector can be provided in order to detect the transfer position of the firefighting vehicle in the transfer carriage.
- the determined weight of the coke can be fed to a computer device and taken into account accordingly after evaluation in the control of the subsequent filling process of the furnace chamber.
- the weight measurement of the coke is preferably carried out immediately after the coke has been squeezed out of the oven chamber, so that it is possible to take the results from the weight measurement into account as early as during the next filling process.
- the measuring device is in this case coupled to the computer device and the computer device is designed to control the measuring process and to evaluate the measurement results and / or to store the measurement results and / or the evaluation results.
- the computer device can also be designed in a corresponding manner for controlling the filling process of the oven chamber.
