Description

Technical field:

[0001] The utility model belongs to the field of coke production, in particular to a coke unloading spray device for a coke quenching car. Background technology:

[0002] The coke quenching car is a supporting equipment for large coke ovens. It usually runs on the track under the coke side of the coke oven. It is used to receive the coke at about 1000 degrees Celsius discharged by the coke guide car, and transport it to the coke quenching chamber for quenching, and finally transport the quenched coke to the designated location.

[0003] In the prior art, coke quenching is mainly divided into wet quenching and dry quenching. In actual use, wet quenching is more commonly used due to its high efficiency and low cost. The traditional wet quenching method is to quench the coke by spraying water directly into the quenching car. However, this method has limited penetration during quenching. The spraying water can often cool the high-temperature coke at the top and middle of the car, but the quenching effect on the bottom of the quenching car is not significant. The coke at the bottom is often not completely extinguished, resulting in red coke, resulting in poor quenching effect. Moreover, the coke temperature after unloading is still high, which affects the subsequent transportation of the coke. Utility model content:

[0004] The purpose of the utility model is to provide a coke unloading spray device for a coke quenching car, and overcome the shortcomings of the above-mentioned prior art, which effectively solves the existing problem of poor wet coke quenching effect.

[0005] The content of the utility model: A coke unloading spray device for a quenching car comprises a quenching car, a water storage tank is installed on the traction boss of the quenching car, a water pump is built into the water storage tank, a water pipe is connected to the output end of the water pump, the output end of the water pipe is connected to a spray box, a plurality of nozzles are evenly installed on the bottom wall of the spray box along the length direction, the spray box is fixedly connected to the side wall of the quenching car by a bracket, and the spray box is located above the coke outlet of the quenching car.

[0006] Furthermore, a temperature probe is installed vertically downward on the bracket, a signal line of the temperature probe is connected to a control cabinet, the control cabinet is installed on the traction boss of the quenching car, and a control line of the water pump is connected to the control cabinet.

[0007] Furthermore, a plurality of temperature probes are installed on the bracket evenly and vertically downward along the length direction.

[0008] Furthermore, a heat-insulating sleeve is provided on the signal line.

[0009] Furthermore, the spray box and the coke outlet have the same length.

[0010] Furthermore, a water supply pipe is vertically connected to the top wall of the water storage tank, and a funnel is installed on the top of the water supply pipe.

[0011] Furthermore, a liquid level sensor is installed on the water storage tank.

[0012] The beneficial effects of the utility model are as follows: by installing a spray box at the coke outlet, the coke can be sprayed and quenched twice during unloading, so that the temperature of the coke after unloading can be reduced to meet the specified required index, avoiding the occurrence of red coke and improving the coke quenching effect.

[0016] In the figure, 1 is a quenching car, 2 is a water storage tank, 3 is a water pump, 4 is a water pipe, 5 is a spray box, 6 is a nozzle, 7 is a bracket, 8 is a coke outlet, 9 is a temperature probe, 10 is a signal line, 11 is a control cabinet, 12 is a control line, 13 is a funnel, 14 is a liquid level sensor, and 15 is a water supply pipe. Specific implementation method:

[0017] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings:

[0018] like Figures 1 to 3 As shown, a coke unloading spray device for a quenching car comprises a quenching car 1, a water storage tank 2 is installed on the traction boss of the quenching car 1, a water pump 3 is installed in the water storage tank 2, the output end of the water pump 3 is connected with a water pipe 4, the output end of the water pipe 4 is connected with a spray box 5, a plurality of nozzles 6 are evenly installed on the bottom wall of the spray box 5 along the length direction, the spray box 5 is fixedly connected to the side wall of the quenching car 1 by a bracket 7, the spray box 5 is located above the coke outlet 8 of the quenching car 1; the spray box 5 is the same length as the coke outlet 8, a water supply pipe 15 is vertically connected to the top wall of the water storage tank 2, a funnel 13 is installed on the top of the water supply pipe 15, and a liquid level sensor 14 is installed on the water storage tank 2.

[0019] Specifically, the spray box 5 installed at the coke outlet 8 can be used to perform secondary spray quenching on the coke during the coke discharge, so that the temperature of the coke after unloading can be reduced to meet the specified required index.

[0020] During actual use, when the quenching car 1 is unloading coke, the coke outlet 8 is opened and the coke is poured out one after another. At this time, the water pump 3 transports the water in the water storage tank 2 to the inner cavity of the spray box 5 through the water pipe 4, and several evenly installed nozzles 6 spray the water evenly onto the coke being unloaded, so that the residual red coke mixed in the coke can be quenched by secondary spraying; since the height of the quenching car 1 is relatively high, the corresponding quenching workbench is relatively high, and the vertically upward connected water supply pipe 15 can quickly replenish water from the quenching workbench to the water storage tank 2.

[0021] like Figures 1 to 3 As shown, a coke unloading spray device for a quenching car is provided. A temperature probe 9 is installed vertically downward on the bracket 7. The signal line 10 of the temperature probe 9 is connected to a control cabinet 11. The control cabinet 11 is installed on the traction boss of the quenching car 1. The control line 12 of the water pump 3 is connected to the control cabinet 11. Several temperature probes 9 are installed evenly and vertically downward along the length direction on the bracket 7, and an insulating sleeve is installed on the signal line 10.

[0022] Specifically, through the intelligent control of the control cabinet 11, the efficiency of the secondary spray quenching can be further improved to prevent waste of resources.

[0023] During actual use, when unloading coke, several temperature probes 9 evenly and vertically installed on the bracket 7 can detect the temperature of the coke and transmit the monitoring data to the control cabinet 11 through the signal line 10. When the coke monitoring temperature reaches the set value, the PLC controller in the control cabinet 11 sends a signal and transmits it to the water pump 3 through the control line 12. At this time, the water pump 3 starts again to transport water to the spray box 5, thereby further realizing the intelligent start-up control of the spray device and preventing waste of resources.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
