DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-8 As shown, a smoke treatment device for steel slag wind quenching and granulation of the utility model comprises a base 1 and a controller 11, a slide slot 12 is provided at the center of the top of the base 1, the slide slot 12 runs through the right side of the base 1, a collecting mechanism is slidably mounted inside the slide slot, a wind blowing chamber 13 matching the position of the slide slot 12 is fixedly mounted on the top of the base 1, a working port 131 is provided at the front side of the wind blowing chamber 13, the top of the wind blowing chamber 13 is a closed structure and a mounting block 14 is fixedly mounted on the top thereof, a circular through slot is provided at the center of the top of the mounting block 14, a connecting slot 15 connected to the circular through slot is provided at the rear side of the mounting block 14, a mounting frame 16 is slidably mounted inside the connecting slot 15, a filter element 17 is fixedly mounted inside the mounting frame 16, and a locking assembly is provided between the mounting frame 16 and the mounting block 14;

[0028] An exhaust duct 141 is fixedly installed on the top of the mounting block 14, and one end of the exhaust duct 141 is connected to an external air suction device. A filter plate 18 is fixedly installed on the upper side of the wind blowing chamber 13. A spray mechanism is installed on the upper side of the wind blowing chamber 13, and the spray mechanism is located above the filter plate 18. The controller 11 is installed on the rear side of the wind blowing chamber 13, and the spray mechanism is electrically connected to the controller 11.

[0029] The length of the air blowing chamber 13 is thirty-five to forty-five meters, the width is twelve to fifteen meters, and the height is ten to fifteen meters. When the steel slag is quenched by wind, the high-temperature liquid slag is first poured into the slag receiving tank, and the slag tank is lifted by a crane to a special slag tank tilting device. The slag tank is flipped, and the high-temperature liquid slag is continuously poured into the intermediate tank. The liquid slag flows out through the slag outlet after the flow is controlled by the intermediate tank. At the same time, the granulator below the slag outlet sprays a high-speed airflow to form a strong impact on the falling steel slag flow, so that the liquid steel slag is first broken and granulated and cooled. The granulated steel slag enters the air blowing chamber 13 through the working port 131, and finally the steel slag enters the collecting mechanism for collection. During this period, the slag particles are dissolved in the air by vaporized water mist and air during flight. From f-Ca0 and f-Mg0, and due to the negative pressure suction generated by the external suction device, the smoke generated during the slag wind quenching is sucked into the exhaust pipe 141, and finally discharged through the exhaust pipe 141. During this period, the smoke is first filtered by the filter plate 18, and the filter plate 18 can give priority to filtering large particles of impurities in the smoke. After filtering, the smoke continues to rise, and is finally filtered by the filter element 17 and discharged through the exhaust pipe 141, thereby filtering the smoke and avoiding pollution to the environment. When replacing the filter element 17, release the locking assembly, lock the mounting frame 16, replace the new mounting frame 16 and the filter element 17, and reinsert them into the connecting groove 15 to lock them. The operation is simple.

[0030] The spray mechanism includes an assembly plate 2, which is fixedly mounted on the left side of the top of the wind blowing chamber 13. A plurality of spray pipes 21 are arranged and rotatably mounted on the upper side of the wind blowing chamber 13. The plurality of spray pipes 21 are all located above the filter plate 18. The left ends of the plurality of spray pipes 21 extend out of the wind blowing chamber 13, and the end faces are all fixedly mounted with gears 22. A plurality of sprinkler heads 23 are arranged on the lower sides of the peripheries of the plurality of spray pipes 21. A first rack 24 is slidably mounted on the lower left side of the assembly plate 2, and the plurality of gears 22 are all meshed with the first rack 24.

[0031] A rectangular frame 25 is fixedly installed at the center of the top of the first rack 24, a circular block 26 is rotatably installed on the left side of the assembly plate 2, the circular block 26 is located inside the rectangular frame 25, and an abutment block 27 is fixedly installed on the periphery of the circular block 26, a mounting frame 281 is fixedly installed on the left side of the assembly plate 2, a motor 29 is fixedly installed on the side of the mounting frame 281 away from the assembly plate 28, and the output shaft of the motor 29 is fixedly connected to the center of the circular block 26 away from the assembly plate 28;

[0032] A mounting pipe 30 is fixedly installed in the center of the left side of the wind blowing chamber 13, and a hose 31 is fixedly installed on the left side of the periphery of several spray pipes 21. One ends of several hoses 31 are respectively fixedly connected to the periphery of the mounting pipe 30. A water inlet pipe 32 is installed around the periphery of the mounting pipe 30, and one end of the water inlet pipe 32 is connected to an external water spraying device. The motor 29 is electrically connected to the controller 11.

[0033] When filtering the smoke, the staff can also start the water spraying equipment, which sends the external water source into the water inlet pipe 32, and then sends it into the spray pipes 21 through the hoses 31. The spray pipes 21 disperse the water evenly through the sprinkler heads 23 and sprinkle it on the filter plate 18. After the water penetrates the filter plate 18, it contacts the smoke and can preferentially fuse the large particles in the smoke to perform preliminary dust reduction. At the same time, the water will eventually fall into the collection mechanism to cool and soak the slag. The staff starts the motor 29 through the controller 11, as shown in FIG. Figure 3 As shown, the output shaft of the control motor 29 is reciprocated and deflected instead of circumferentially rotating. The output shaft of the motor 29 then drives the circular block 26 to reciprocate and deflect. During the reciprocating deflection of the circular block 26, the abutment block 27 is driven to abut against the inner walls of the two sides of the rectangular frame 25 in turn. Therefore, the rectangular frame 25 will continue to reciprocate. During the reciprocating movement of the rectangular frame 25, the first rack 24 is driven to engage with a plurality of gears 22, driving the plurality of gears 22 to reciprocate and deflect. As a result, the reciprocating deflection of the plurality of spray pipes 21 changes the spraying angle of the plurality of sprinkler heads 23, so that the spraying area of ​​the plurality of spray pipes 21 is larger. When the water is sprinkled, it acts on the filter plate 18, and the filter plate 18 can also be backwashed from top to bottom, and the filter plate 18 is continuously cleaned to avoid the filter holes of the filter plate 18 being blocked after long-term use, affecting the filtering effect. No manual cleaning is required, and the operation is simple and convenient.

[0034] The locking assembly includes a locking block 33, a locking groove 333 is provided on the front side of the bottom of the connecting groove 15, and an insertion groove 34 matching the position of the locking groove 333 is provided on the front side of the bottom of the mounting frame 16. The locking block 33 is slidably assembled in the locking groove 333, and an inclined surface 341 is provided on the upper part of the locking block 33 close to the circular through groove. A plurality of first springs 35 are fixedly installed on the bottom of the locking block 33, and the lower ends of the plurality of first springs 35 are respectively fixedly connected to the inner wall of the bottom side of the locking groove 333, and a plurality of second springs 331 are fixedly installed on the inner wall of the connecting groove 15 away from the groove, and a push plate 332 is fixedly installed on one end of the plurality of second springs 331 close to the groove of the connecting groove 15, and the push plate 332 abuts against the mounting frame 16 on the side close to the groove of the connecting groove 15;

[0035] A second rack 36 is slidably mounted in the center of the right side of the assembly plate 2, a pull rope 37 is fixedly mounted on the bottom of the locking block 33, one end of the pull rope 37 extends out of the mounting block 14 and is fixedly connected to the front part of the second rack 36 close to the mounting block, a connecting rod is fixedly mounted in the center of the circular block 26 close to the mounting block 14, one end of the connecting rod close to the mounting block 14 passes through the assembly plate 2 and an incomplete tooth 38 is fixedly mounted on the end surface, and the incomplete tooth 38 is meshed with the second rack 36.

[0036] When the filter element 17 is replaced, the staff controls the output shaft of the motor 29 to rotate one circle, and then the connecting rod drives the incomplete gear 38 to rotate one circle. The incomplete gear 38 drives the second rack 26 to move a certain distance by meshing with the second rack 26. Therefore, the second rack 26 generates a pulling force to drive the locking block 33 to retract into the locking groove 333 through the pull rope 37, thereby completing the unlocking of the installation frame 16. The second springs 331 are stretched synchronously, and the installation frame 16 is pushed out of the connection groove 15, and the staff can directly take it out for replacement.

[0037] After the incomplete teeth 38 rotate one circle to reset, the first springs 35 are stretched to drive the second gear 26 to reset. When the filter element 17 is installed later, it is only necessary to push the installation frame 16 into the connecting groove 15. After the installation frame 16 enters the connecting groove 15, it will push the pushing plate 332 to move and compress the second springs 331 until the end of the installation frame 16 abuts against the inclined surface 341, and the locking block 33 is pushed into the locking groove 333 until the insertion groove 34 is aligned with the locking groove 333. The locking block 33 extends upward onto the locking groove 333 to lock the installation frame 16 to a limit position. The locking is convenient. You only need to push the installation frame 16 into the connecting groove 15, and the installation is fast.

[0038] The collecting mechanism includes a collecting box 4, which is slidably assembled inside the slide 12. A water filter plate 41 is fixedly installed on the lower side of the collecting box 4. An opening connected to the slide 12 is opened on the left side of the base 1.

[0039] The collecting box 4 can collect steel slag and water, and the water can cool the steel slag. The flying slag particles fall into the water to complete the final splitting and granulation. The processed steel slag has uniform particle size and the particle diameter is within three millimeters. When draining, the valve can be opened to drain. The filter plate 41 can separate the steel slag from the water. When the steel slag is subsequently processed, the collecting box 4 can be pulled out of the chute 12 for processing.

[0040] An entrance is provided at the rear side of the wind blowing chamber 13 , a closed door 42 matching the entrance is hingedly mounted at the rear side of the wind blowing chamber 13 , and a climbing ladder 421 is provided at the right rear side of the wind blowing chamber 13 .

[0041] The staff can open the closed door 42 to enter the wind blowing chamber 13. The closed door 42 and the wind blowing chamber 13 can be locked to prevent the slag from jumping out, and the climbing ladder 421 is convenient for the staff to climb and replace the filter element 17.
