[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-9 The present invention provides a technical solution: a spraying mechanism for treating waste incineration slag, comprising: a slag spraying system and a dewatering system, wherein the slag spraying system is connected to the dewatering system, the slag spraying system transfers and sprays the slag produced by waste incineration to cool it down, and then transfers it to the dewatering system for dewatering.

[0020] See Figure 1 and 2 The slag spraying system includes a first slag transfer device 1, a conveying device 2, and a second slag transfer device 3, as well as an external sealing box for the above three. The first slag transfer device 1 is connected to the waste incineration unit and the conveying device 2. The conveying device 2 is connected to the second slag transfer device 3. The first slag transfer device 1 receives the slag produced by waste incineration and transfers it to the conveying device 2, and then to the second slag transfer device 3, from which it is transferred to the dewatering system.

[0021] See Figure 3 The slag first transfer device 1 includes a first transfer plate 12, a docking cylinder 11 is fixedly installed on the top of the first transfer plate 12, a side sprayer 111 is installed on the side of the docking cylinder 11, the docking cylinder 11 connects to the waste incineration device, receives slag, performs preliminary water spraying and cooling through the side sprayer 111, and then falls into the first transfer plate 12. The first transfer plate 12 is movably set inside the sealed box. The side of the first transfer plate 12 is connected to the material equalization drive structure 13. The material equalization drive structure 13 pushes and pulls the first transfer plate 12 back and forth, so that the slag is relatively evenly spread in the first transfer plate 12. At the same time, when it is transferred to the conveying device 2, due to the back and forth movement, the slag can be spread more evenly on the conveying device 2. The material equalization drive structure 13 includes a first motor 131, the output shaft of the first motor 131 is fixedly connected to a turntable 132, an eccentric wheel 134 is rotatably mounted on the turntable 132, the eccentric wheel 134 is slidably connected to a first elongated guide ring 133, the first elongated guide ring 133 is fixedly connected to a side connecting rod 135, the side connecting rod 135 is fixedly connected to the side of a first transfer plate 12, and a sliding shaft is provided on the opposite side of the first transfer plate 12. The sliding shaft and the side connecting rod 135 are movably connected to the sealing box. The first motor 131 drives the turntable 132 to rotate, which in turn drives the eccentric wheel 134 to move in a circular motion. This pushes and pulls the first elongated guide ring 133 away from or towards the sealing box. Then, the side connecting rod 135 pushes and pulls the first transfer plate 12 to move back and forth, so that the slag falls relatively evenly into the first transfer plate 12. In addition, it can also throw the slag relatively evenly out from the gap of the first transfer plate 12.

[0022] See Figure 3 and Figure 4 The bottom of the first transfer plate 12 is provided with a guide structure 14 for guiding the first transfer plate 12 when it is pushed and pulled back and forth. The guide structure 14 includes a guide rail 141, a traveling wheel structure 142, and a second hinge seat 143. The traveling wheel structure 142 is slidably disposed on the guide rail 141. The traveling wheel structure 142 includes a pair of pulleys 1421 that are rolledly connected to the guide rail 141. The traveling wheel structure 142 also includes a first hinge seat 1422. The second hinge seat 143 is fixedly installed on the bottom of the first transfer plate 12. The first hinge seat 1422 and the second hinge seat 143 are hinged by a hinge shaft 144, and the hinge axis is perpendicular to the rolling direction of the pulleys 1421. The linear motion of the walking wheel structure 142 and the guide rail 141 supports the first transfer plate 12 and also assists the first transfer plate 12 in reciprocating motion.

[0023] See Figure 3 The guide structure 14 is connected to the lifting drive structure 15. The lifting drive structure 15 drives the guide structure 14 to lift, thereby driving the tail end of the first transfer plate 12 to lift, adjusting the tilt angle of the first transfer plate 12, and adjusting the output of the first transfer plate 12.

[0024] The lifting drive structure 15 includes a second motor 151, the output shaft of the second motor 151 is fixedly connected to a lead screw 152, the lead screw 152 is threadedly connected to a lifting arm 154, the lifting arm 154 is fixedly connected to a guide rail 141, and the lifting arm 154 is slidably connected to two symmetrical guide rods 153. The second motor 151 drives the lead screw 152 to rotate, which in turn drives the lifting arm 154 to rise and fall along the two guide rods 153. This, in turn, drives the tail end of the first transfer plate 12 to rise and fall through the guide structure 14, causing the first transfer plate 12 to rotate axially around the side connecting rod 135 and the sliding shaft. This adjusts the inclination of the first transfer plate 12. When the discharge port of the first transfer plate 12 is lower than the entire first transfer plate 12, the discharge volume is greater. When the discharge port of the first transfer plate 12 is higher than the entire first transfer plate 12, the discharge stops, and the slag accumulates briefly in the first transfer plate 12 to coordinate with the subsequent transfer rhythm.

[0025] See Figure 5In order to accommodate the rotation of the first transfer plate 12, an elongated guide groove 1431 is provided on the second hinge seat 143. The hinge shaft 144 is slidably connected in the elongated guide groove 1431, so that the walking wheel structure 142 and the second hinge seat 143 can move relative to each other within a small range.

[0026] See Figure 1 The top of the sealing box of the conveying device 2 is equipped with a top sprayer 21 and an atomization recovery pipe 22. The conveying device 2 receives the slag transferred from the first slag transfer device 1 and sprays it to cool it down. The generated atomized gas is drawn and treated by the atomization recovery pipe 22, and then the sprayed slag is sent to the second slag transfer device 3.

[0027] See Figure 6 The second slag transfer device 3 includes a second transfer plate 31, which is connected to the lower end of the conveying device 2. The side of the second transfer plate 31 is connected to a linear push-pull module 33, and a first cylinder 32 is set below the tail end of the second transfer plate 31. The linear push-pull module 33 pushes the second transfer plate 31 so that its discharge port reaches the slag filter cylinder 7 of the dewatering system; The tail end of the second transfer plate 31 is lifted by the first cylinder 32, so that its front discharge port is tilted downward and slightly inserted into the port of the slag filter cylinder 7, so that the slag falls into the slag filter cylinder 7 more accurately and faster.

[0028] The linear push-pull module 33 includes a second cylinder 331, a guide wheel 332, and a second elongated oval guide ring 333. The second cylinder 331 is fixedly installed on the outer surface of the sealing box. The telescopic end of the second cylinder 331 is rotatably connected to the guide wheel 332. The guide wheel 332 is slidably connected to the second elongated oval guide ring 333. The second elongated oval guide ring 333 is fixedly installed on the sealing box wall. The guide wheel 332 is rotatably connected to the second transfer plate 31 through a connecting rod. The second cylinder 331 drives the guide wheel 332 to move linearly along the second elongated guide ring 333, thereby driving the second transfer plate 31 to move linearly.

[0029] See Figure 7 The dewatering system includes a liquid collection tray 4, a rotary drive platform 5, a lifting arm 6, a slag filter cylinder 7, and a centrifugal dewatering structure 8; Three lifting arms 6 are arranged in an equilateral triangle on the rotary drive platform 5. In the initial state, the lifting arms 6 correspond to three work stations, namely the loading station, the dewatering station and the unloading station. The loading station is located at the second slag transfer device 3. The front end of the lifting arm 6 is movably hung with the slag filter cylinder 7. The liquid collection plate 4 is set below the moving range of the slag filter cylinder 7. The centrifugal dewatering structure 8 is set above the liquid collection plate 4 of the dewatering station. The rotary drive platform 5 drives the lifting arm 6 to move the slag filter cylinder 7 to the feeding station, namely the second slag transfer device 3, to receive the sprayed slag. Then, it rotates to the dewatering station. During the rotation, the lifting arm 6 lifts the slag filter cylinder 7. When it reaches the centrifugal dewatering structure 8, the lifting arm 6 puts the slag filter cylinder 7 into the centrifugal dewatering structure 8. The centrifugal dewatering structure 8 drives the slag filter cylinder 7 to rotate at high speed for centrifugal dewatering. Then, it is taken out from the centrifugal dewatering structure 8 and driven by the rotary drive platform 5 to the unloading station for unloading. During this process, the feeding, dewatering and unloading operations are carried out simultaneously.

[0030] See Figure 8 The slag filter cylinder 7 includes a filter cylinder body 71, with a stabilizing seat 72 at the bottom of the filter cylinder body 71. A blocking block 73 is integrally connected to the side of the stabilizing seat 72. The centrifugal dewatering structure 8 includes a dewatering cylinder 82, with a rotating platform 86 at the bottom inside the dewatering cylinder 82. A protrusion 861 is integrally provided on the inner wall of the side of the rotating platform 86. The protrusion 861 cooperates with the blocking block 73 to radially fix the rotating platform 86 and the filter cylinder body 71, allowing them to rotate synchronously. The rotating platform 86 is inserted into the stabilizing seat 72 to enhance the stability of the rotation of the filter cylinder body 71. At the same time, the protrusion 861 and the blocking block 73 are located on the same track. The rotating platform 86 drives the protrusion 861 to rotate and contact the blocking block 73, ultimately driving the filter cylinder body 71 to rotate.

[0031] A reinforcing ring 74 is integrally connected to the outer periphery of the upper port of the filter cylinder body 71. The reinforcing ring 74 has symmetrical open circular grooves 741 on its side. The open circular grooves 741 are inserted into the hanging wheels of the lifting arm 6 to realize the movable mounting of the filter cylinder body 71 and the lifting arm 6. When the filter cylinder body 71 is placed in the centrifugal dewatering structure 8, the filter cylinder body 71 stops descending because the rotating platform 86 has a certain height. The lifting arm 6 continues to descend, and the hanging wheels disengage from the open circular grooves 741, so that the filter cylinder body 71 can rotate normally.

[0032] The centrifugal dehydration structure 8 also includes a support platform 81, which spans across the collection tray 4. A dehydration cylinder 82 is fixedly installed on the support platform 81. A conduit is also installed at the bottom of the dehydration cylinder 82, which is connected to the collection tray 4. The dehydrated water flows into the collection tray 4 through the conduit for further processing.

[0033] A centrifugal drive motor 85 is installed on the support platform 81. The output end of the centrifugal drive motor 85 is fixedly connected to the rotating platform 86, and the rotating platform 86 is driven to rotate at high speed by the centrifugal drive motor 85.

[0034] The centrifugal dehydration structure 8 also includes a cover 84, which is rotatably connected to the dehydration cylinder 82. A third cylinder 83 is provided between the cover 84 and the dehydration cylinder 82. The telescopic end of the third cylinder 83 is rotatably connected to the cover 84, and the main body of the third cylinder 83 is rotatably connected to the dehydration cylinder 82. Through the telescopic drive of the third cylinder 83, the cover 84 is driven to close and open the dehydration cylinder 82.

[0035] See Figure 9 The sealing cover 841 is fixedly connected inside the cover 84. The sealing cover 841 is movable and presses against the port of the filter cylinder body 71 to prevent slag from being thrown out during rotation. At the same time, it fixes the filter cylinder body 71 axially to prevent it from moving. The guide plate 842 is fixedly installed on the lower surface of the sealing cover 841. The guide plate 842 is provided with a ball ring 843 on the side. The balls of the ball ring 843 are rolled and connected to the inner wall of the filter cylinder body 71 to prevent the upper port of the filter cylinder body 71 from swinging during rotation.

[0036] The upper end of the dewatering cylinder 82 has a notch for the lifting arm 6 to enter and exit, so that the lifting arm 6 can smoothly enter and exit the dewatering cylinder 82 at the mounting point of the filter cylinder body 71, and finally the lifting arm 6 can be dismounted from the mounting of the filter cylinder body 71.

[0037] Working principle: Feeding and initial cooling: The slag enters the docking cylinder 11 from the waste incineration unit and is initially cooled by water spraying from the side sprayer 111.

[0038] The slag falls into the first transfer plate 12, and is evenly distributed and conveyed forward by the uniform material driving structure 13.

[0039] Conveying and secondary spraying: The slag is fed into the conveying device 2 by the first transfer plate 12 and then cooled by the top sprayer 21.

[0040] The generated atomized gas is recovered and processed by the atomization recovery tube 22.

[0041] Transferred to the dehydration system: After being sprayed, the slag is precisely fed into the slag filter cylinder 7 via the second transfer plate 31.

[0042] The second transfer plate 31 can be adjusted in position and tilt angle by the linear push-pull module 33 and the first cylinder 32 to ensure accurate feeding.

[0043] Centrifugal dehydration treatment: The slag filter cylinder 7 is driven by the rotary drive platform 5 and passes through the three stations of feeding, dewatering and unloading in sequence.

[0044] At the dewatering station, the slag filter cylinder 7 is driven to rotate at high speed by the centrifugal dewatering structure 8 to achieve centrifugal dewatering.

[0045] During the dewatering process, the slag filter cylinder 7 is axially fixed by the sealing cover 841 to prevent the material from being thrown out, and is kept in rotational stability by the guide plate 842 and the ball ring 843.

[0046] Continuous operation and wastewater recycling: The three workstations can operate simultaneously, enabling continuous processing.

[0047] The wastewater generated during dehydration is collected in collection tray 4 for subsequent treatment.

[0048] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
