[0021] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1 and Figure 2 As shown, the utility model provides a spray device for a dry coke quenching tank carport, comprising two baffles 1, a water tank 2, a water pump 3, a spray pipe 4, a flow control valve 5, a plurality of pipes 6, two water receiving tanks 7 and a controller, wherein the two baffles 1 are respectively fixedly connected to the front and rear ends of the top surface of the carport 10, the water inlet of the water tank 2 is connected to an external water source, the water outlet of the water tank 2 is connected to the water inlet of the water pump 3, the water outlet of the water pump 3 is connected to one end of one of the pipes 6, the other end of one of the pipes 6 is connected to the water inlet of the flow control valve 5, the water outlet of the flow control valve 5 is connected to the spray pipe 4, the spray pipe 4 is located above the top surface of the carport 10, the two water receiving tanks 7 are respectively fixedly connected to the outer sides of the left and right sides of the carport 10, the bottoms of the two water receiving tanks 7 are respectively connected to the water inlet of the water tank 2 through the two pipes 6; the controller is electrically connected to the water pump 3 and the flow control valve 5.

[0023] In a specific implementation, an encoder is installed at the bottom of the dry coke quenching tank car 9, and the encoder can detect the distance between the dry coke quenching tank car 9 and the front end of the carport 10 in real time and send a position signal carrying the distance information between the dry coke quenching tank car 9 and the front end of the carport 10 to the controller; the controller will preset a distance, which is the distance between the dry coke quenching tank car 9 and the front end of the carport 10; the controller compares the position signal sent by the encoder in real time with the preset distance, so as to determine whether the distance between the dry coke quenching tank car 9 and the front end of the carport 10 is less than or equal to the preset distance, and then determine Whether the dry coke quenching tank car 9 arrives at the designated position at the front end of the carport 10, the distance between the front end of the carport 10 and the designated position is the preset distance; if not, the water pump 3 and the flow control valve 5 are still in the closed state, and the dry coke quenching tank car 9 continues to move towards the carport 10; when several coke quenching tank cars 9 arrive, the controller controls the water pump 3 and the flow control valve 5 to be turned on, and controls the flow control valve 5 to be in a largely open state, so that the water flow sprayed by the spray pipe 4 is larger, so that when the dry coke quenching tank car 9 passes through the carport 10, the spray pipe 4 has a more obvious cooling effect on the top surface of the carport 10.

[0024] Secondly, the controller will preset the first time, which is the time when the controller controls the flow control valve 5 to be greatly opened. When the controller determines that the first dry quenching coke tank car 9 has arrived, the flow control valve 5 is greatly opened, and the controller starts timing. The flow control valve 5 remains in a greatly opened state for the first time; when the first time is over, the controller controls the flow control valve 5 to be converted into a slightly opened state. At this time, the water flow sprayed by the spray pipe 4 is small, but the spray pipe 4 can still continue to cool the top surface of the carport 10;

[0025] In addition, the controller will preset a second time, and the first time is less than the second time, and the second time is the interval time between adjacent dry quenching coke tank cars 9 arriving at the carport; specifically, the timing starts when the controller determines that the previous dry quenching coke tank car 9 arrives at the designated position at the front end of the carport 10; if the controller determines that the next dry quenching coke tank car 9 arrives at the designated position at the front end of the carport 10 within the second time, the controller controls the flow control valve 5 to open significantly to cool down the top surface of the carport 10; if the controller determines that the next dry quenching coke tank car 9 does not arrive at the designated position at the front end of the carport 10 within the second time, the controller controls the water pump 3 and the flow control valve 5 to close to stop the spray cooling process on the top surface of the carport 10, until the controller determines that a dry quenching coke tank car 9 arrives at the front end of the carport 10 next time, and then opens the water pump 3 and the flow control valve 5.

[0026] After the water pump 3 and the flow control valve 5 are turned on by the controller, the water pump 3 pumps out the water in the water tank 2 and transports the water to the spray pipe 4 through the pipeline 6 and the flow control valve 5, and the spray pipe 4 sprays the water onto the top surface of the carport 10, thereby cooling the top surface of the carport 10, avoiding overburning of the top surface of the carport 10, and reducing safety hazards; the flow control valve 5 is continuously in a slightly open state during the time period between the first time and the second time, and can maintain the spray cooling process of the top surface of the carport 10 to prevent the water flow remaining on the top surface of the carport 10 from evaporating and forming scale, thereby ensuring a good subsequent cooling effect on the top surface of the carport 10. By setting two baffles 1 and two water receiving grooves 7, and fixing the two baffles 1 at the front and rear ends of the top surface of the carport 10 respectively, the two water receiving grooves 7 are fixedly connected to the outer sides of the left and right sides of the carport 10 respectively, and the bottoms of the two water receiving grooves 7 are connected to the water inlet of the water tank 2 through two pipes 6 respectively, so that the water sprayed onto the top surface of the carport 10 can be blocked by the two baffles 1, flow into the water receiving grooves 7 from the left and right sides of the top surface of the carport 10, and then flow back into the water tank 2, so as to realize water circulation and save water resources.

[0027] Optionally, a liquid level sensor is installed inside the water tank 2, and the liquid level sensor is electrically connected to the controller.

[0028] It should be noted that when the liquid level sensor detects the liquid level in the water tank 2, it is necessary to shut down the water pump 3 and the flow control valve 5 in the controller, and perform the detection after the spray cooling process is completely stopped, so as to avoid the liquid level sensor making misjudgments due to the unstable liquid level in the water tank 2 during the spray cooling process.

[0029] Optionally, a spraying device for a dry quenching coke tank carport further includes an automatic control valve 8, and the water tank 2 is connected to an external water source via the automatic control valve 8; the automatic control valve 8 is electrically connected to the controller.

[0030] Specifically, the automatic control valve 8 in the present invention can be a solenoid valve or an electric valve.

[0031] In a specific implementation, when the spray cooling process stops, the liquid level sensor detects that the liquid level in the water tank 2 drops to a preset height and then sends a water replenishment signal to the controller. The controller controls the automatic control valve 8 to open according to the water replenishment signal, and the external water source injects water into the water tank 2 through the automatic control valve 8; when the liquid level sensor detects that the liquid level in the water tank 2 reaches a preset height, the liquid level sensor sends a stop water replenishment signal to the controller, and the controller controls the automatic control valve 8 to close according to the stop water replenishment signal, thereby completing the water replenishment process of the water tank 2.

[0032] Optionally, a spraying device for a dry coke quenching tank carport further includes a filter assembly, which is installed at the water outlet of the water tank 2. By providing the filter assembly, when the water pump 3 extracts water from the water tank 2, scale or impurities that may exist in the water tank 2 can be filtered to ensure the cleanliness of the water extracted by the water pump 3 and avoid clogging of the spray pipe 4.

[0033] Optionally, the spray pipe 4 is in the shape of a long tube, two ends of the spray pipe 4 are respectively close to the inner side surfaces of the two baffles 1 , and a plurality of spray holes are opened on the spray pipe 4 .

[0034] Specifically, the cross-sectional shape of the spray pipe 4 can be circular or rectangular. Preferably, the cross-sectional shape of the spray pipe 4 in the present invention is circular.

[0035] The length of the long tubular spray pipe 4 is the same as the length of the top surface of the carport 10. Therefore, during spraying, the top surface of the carport 10 can be sprayed over a large area with high spraying efficiency.

[0036] Optionally, the lengths of the two water receiving troughs 7 are the same as the lengths of the left and right sides of the carport 10 .

[0037] The length of the two water receiving grooves 7 is the same as the length of the left and right sides of the carport 10, so that the spraying water can eventually flow into the two water receiving grooves 7 to the greatest extent under the action of the two baffles 1, avoiding waste of water resources, and then flow into the water tank 2 through the pipes 6 connected to the two water receiving grooves 7, thereby completing the water circulation.

[0038] Optionally, the filter assembly includes a shell, a first filter and a second filter, the first filter and the second filter are installed in parallel in the shell, and the first filter is located near the water outlet of the water tank 2, and the aperture of the filter holes opened on the first filter is smaller than the aperture of the filter holes opened on the second filter.

[0039] In a specific embodiment, the water inlet of the shell is connected to the inside of the water tank 2, and the water outlet of the shell is the water outlet of the water tank 2. When the water pump 3 draws water from the water tank 2, the water can enter the shell through the water inlet of the shell, first pass through the second filter screen for the first filtration, then pass through the first filter screen for the second filtration, and finally spray to the top surface of the carport 10 through the water pump 3, the flow control valve 5 and the spray pipe 4.

[0040] The first filtration can filter out larger impurities in the water tank 2 , and the second filtration can filter out smaller impurities in the water tank 2 , thereby ensuring the cleanliness of the water pumped by the water pump 3 .

[0041] In summary, the spray device provided by the utility model can cool down the top surface of the carport 10, avoid overburning of the top surface of the carport 10, and reduce safety hazards; the controller controls the start and stop of the flow control valve 5 and the water pump 3 by receiving the position signal of the encoder, thereby realizing automatic control of the water flow, which not only ensures that the spray device continuously cools down the top surface of the carport 10 and prevents the formation of scale, but also can automatically shut down the water flow when no dry quenching tank car 9 passes within a certain period of time, thereby avoiding waste of water resources; the baffle 1 and the water receiving trough 7 are provided to achieve the recycling of water resources.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
