[0021] As Figure 1-2 shown, the dry slag cooling treatment device of the present invention includes a shell 1, an induced draft fan 2, a belt conveyor 5 and a hammer crusher 7. The induced draft fan 2 is fixed on the left side of the shell 1. The input end of the induced draft fan 2 is fixedly connected with an exhaust duct 3. The other end of the exhaust duct 3 is inlaid and communicated with the left end of the shell 1. An air volume regulating valve 4 is installed in the middle of the exhaust duct 3. A belt conveyor 5 is arranged inside the shell 1. A cooling component 6 is arranged above the shell 1. A slag hopper 8 is fixedly arranged at the upper left of the shell 1. A hammer crusher 7 is arranged at the lower right of the shell 1. A slag bin 11 is fixedly arranged below the hammer crusher 7.

[0022] On the basis of the above structure, the cooling component 6 includes a cooling fan 61, a three-way joint 62, a connecting pipe 63, a diverging pipe 64 and a cold air nozzle 65. The cooling fan 61 is fixedly installed on the top of the shell 1. The output end of the cooling fan 61 is fixedly connected with a three-way joint 62. Both air outlet ends of the three-way joint 62 are fixedly connected with a connecting pipe 63. The ends of the two connecting pipes 63 far from the three-way joint 62 are respectively fixedly connected to the right ends of the two diverging pipes 64. A plurality of cold air nozzles 65 are evenly inlaid and communicated along the length direction at the bottom ends of the two diverging pipes 64.

[0023] In this embodiment, through the setting of the three-way joint 62 and the two connecting pipes 63, it is convenient to supply cold air to the two diverging pipes 64 simultaneously when the cooling fan 61 is turned on.

[0024] On the basis of the above structure, the two diverging pipes 64 are symmetrically arranged before and after about the central axis of the shell 1. A plurality of cold air nozzles 65 all penetrate through the upper end inside the shell 1 and are fixedly connected with the shell 1.

[0025] In this embodiment, by using a plurality of cold air nozzles 65 evenly arranged at the bottom ends of the two diverging pipes 64, it is convenient to quickly cool the dry slag conveyed on the surface of the belt conveyor 5.

[0026] On the basis of the above structure, the right end discharge port of the outer shell 1 is in communication with the top feed port of the hammer crusher 7, and the bottom discharge port of the hammer crusher 7 is in communication with the top feed port of the slag bin 11.

[0027] In this embodiment, the hammer crusher 7 is used to conveniently crush the dry slag sufficiently before it falls into the slag bin 11.

[0028] On the basis of the above structure, a level gauge 9 is fixedly provided on the outer wall of the upper right side of the slag hopper 8, a first shut-off door 10 is installed at the bottom of the slag hopper 8, a second shut-off door 12 is installed at the bottom of the slag bin 11, and a pressure relief valve 13 and a bag filter 14 are installed in the upper right of the slag bin 11.

[0030] The working principle of the present utility model is as follows:

[0031] During use, first, the dry slag is discharged into the slag hopper 8, and the level gauge 9 monitors the dry slag content in the slag hopper 8. When it is detected that the dry slag reaches two-thirds of the volume of the slag hopper 8, the level gauge 9 sends a signal and opens the first shut-off door 10 to start discharging slag into the outer shell 1, so that the dry slag falls on the belt conveyor 5 in the transmission state and starts to be conveyed to the right. Then, the cooling fan 61 is started, and through the three-way pipe 62, the connecting pipe 63, the shunt pipe 64 and a number of equally spaced cold air nozzles 65, it is convenient to sufficiently cool the dry slag on the belt conveyor 5. And the induced draft fan 2 is started, and the hot air can be discharged from the outer shell 1 through the exhaust pipe 3. This device can realize the sufficient cooling of the dry slag, and the temperature of the dry slag can be reduced from 400 °C to 150 °C during the conveying process, with high cooling efficiency.

[0032] The cooled dry slag can fall into the hammer crusher 7 for sufficient crushing, and the crushed dry slag can fall into the slag bin 11 and wait for vehicle transfer. Through the setting of the pressure relief valve 13, the internal pressure of the slag bin 11 can be avoided from being too high, and under the action of the bag filter 14, it can play a role in dust reduction. Finally, the dry slag in the slag bin 11 can be discharged and transferred by opening the second shut-off door 12.

[0033] The above is only the preferred specific embodiment of the present utility model, and it is not intended to limit the protection scope of the present utility model; all equivalent changes, modifications, substitutions and variations made by those skilled in the art in this technical field according to the concept of the present utility model on the basis of the existing technology through logical analysis, reasoning or limited experiments shall fall within the protection scope determined by the claims.
