DETAILED DESCRIPTION
[0027] The present invention will be further described in detail below with reference to the accompanying drawings.
[0028] like Figures 1 to 10 As shown, in order to achieve the technical effect of "exchanging and utilizing the residual heat in the slag while crushing the slag", the structure and function of the waste incineration slag cooling treatment device are described in detail below;
[0029] The waste incineration slag cooling treatment device includes a crushing box 11, two pusher plates 22 are slidably connected to the crushing box 11, a screening plate 41 is slidably connected to the bottom of the crushing box 11, and a crushing mechanism 3 is fixedly connected to the crushing box 11;
[0030] When using, Figure 1 As shown, the incineration slag that needs to be processed is placed in the crushing box 11, and the crushing mechanism 3 is used to crush the incineration slag in the crushing box 11. At the same time, the crushing mechanism 3 exchanges the residual heat in the incineration slag while crushing. Since large objects are large in volume, the internal heat of large objects is not easy to be heat exchanged. Therefore, the crushing mechanism 3 is used to crush the incineration slag and complete the heat exchange while crushing. Not only can the heat exchange be effectively carried out, but the crushing and cooling of the incineration slag are also completed, which is convenient for the subsequent treatment of the incineration slag. At the same time, in order to ensure that the crushing mechanism 3 can fully crush the incineration slag during the crushing process, two pusher plates 22 are used to continuously slide in the crushing box 11 to push the incineration slag to move and adjust the position of the incineration slag so that the crushing mechanism 3 can fully crush the incineration slag. The crushed incineration slag is screened by the screening plate 41. At the same time, the screening plate 41 can also perform a second heat exchange on the incineration slag, so that the residual heat in the incineration slag is utilized and the incineration slag can be quickly cooled.
[0031] Further, such as Figure 3 As shown, in order to promote the incineration slag to move in the crushing box 11, the incineration slag is completely crushed;
[0032] The crushing box 11 is fixedly connected to two telescopic mechanisms I 21, and two pusher plates 22 are respectively fixedly connected to the telescopic ends of the two telescopic mechanisms I 21;
[0033] The telescopic mechanism I 21 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 21 drives the push plate 22 to move, so that the push plate 22 slides in the crushing box 11, thereby pushing the incineration slag to move, and then adjusting the position of the incineration slag, so that the incineration slag at different positions can be crushed and heat exchanged by the crushing mechanism 3, thereby achieving crushing and cooling treatment of the incineration slag;
[0034] like Figure 4 As shown, in order to facilitate the collection of the incineration slag filtered by the screening plate 41, a conical cavity 12 is fixedly connected to the bottom of the crushing box 11, and the screening plate 41 is slidably connected between the crushing box 11 and the conical cavity 12;
[0035] The area of the upper end of the conical cavity 12 is larger than the area of the lower end of the conical cavity 12, so that the incineration slag filtered by the screening plate 41 enters the conical cavity 12, and after being gathered by the conical cavity 12, is discharged from the bottom of the conical cavity 12;
[0036] Further, such as Figure 5 and Figure 6 As shown, the structure and function of the crushing mechanism 3 are described in detail below;
[0037] The crushing mechanism 3 includes a telescopic mechanism II 31, which is fixedly connected to the outside of the crushing box 11. The telescopic end of the telescopic mechanism II 31 is fixedly connected to the crushing box 32. The bottom of the crushing box 32 is fixedly connected to a plurality of crushing plates 33. The bottom of the crushing plates 33 is set in a conical shape. The crushing box 32 and the crushing plates 33 are connected;
[0038] When in use, the telescopic mechanism II 31 is activated. The telescopic mechanism II 31 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 31 drives the crushing box 32 to move up and down. The crushing box 32 drives the crushing plates 33 to move up and down, so that the multiple crushing plates 33 are inserted into the incineration slag, so that the multiple crushing plates 33 crush the incineration slag.
[0039] Furthermore, the crushing box 32 is fixedly connected to an inlet pipe 34 and a discharge pipe 36, the inlet pipe 34 is fixedly connected to a plurality of branch pipes I 35, and the discharge pipe 36 is fixedly connected to a plurality of branch pipes II 37;
[0040] The heat exchange liquid pipeline is pre-connected to the inlet pipeline 34, so that the liquid that needs to absorb the heat in the incineration slag enters the multiple branch pipelines I 35 through the inlet pipeline 34, and then enters the multiple crushing plates 33 through the multiple branch pipelines I 35. When the crushing plates 33 crush the incineration slag, the heat in the incineration slag is taken away, completing the heat exchange while reducing the temperature of the incineration slag. The liquid that has completed the heat exchange enters the multiple branch pipelines II 37, enters the discharge pipeline 36 through the branch pipeline II 37, and is discharged through the discharge pipeline 36.
[0041] Furthermore, in order to ensure sufficient heat exchange of the liquid, a plurality of branch pipes I 35 are respectively extended into one side of the bottom of the crushing plate 33, and a plurality of branch pipes II 37 are respectively extended into the other side of the top of the crushing plate 33;
[0042] The liquid enters the bottom of the crushing plate 33. As the liquid gradually increases, the liquid at the bottom of the crushing plate 33 gradually increases and is discharged from the branch pipe II 37 at the top. This arrangement can maximize the time the liquid stays in the crushing plate 33 to ensure sufficient heat exchange.
[0043] Furthermore, the process of secondary heat exchange of the sieve plate 41 is described in detail below;
[0044] The sieve plate 41 is provided with a plurality of tapered holes 42. The interior of the sieve plate 41 is hollowed out. Two communication pipes 43 are fixedly connected to both sides of the sieve plate 41. The communication pipes 43 are connected to the interior of the sieve plate 41.
[0045] One of the two communicating pipes 43 is connected to the heat exchange liquid pipe, so that the liquid enters the screen plate 41 through the communicating pipe 43, removes the heat of the incineration slag passing through the tapered holes 42 on the screen plate 41, and also removes the heat of the incineration slag located on the upper side of the screen plate 41. While completing the cooling of the incineration slag, the tapered holes 42 can also complete the screening of the incineration slag and utilize the residual heat in the incineration slag.
[0046] Furthermore, since the upper side of the screening plate 41 needs to withstand the crushing force of the crushing plate 33 on the incineration slag when it is pressed down, the diameter of the upper end of the tapered hole 42 is larger than the diameter of the lower end of the tapered hole 42, as shown in FIG. Figure 8 As shown, a trapezoidal structure is formed inside the screening plate 41, which increases the strength of the screening plate 41 and ensures that the screening plate 41 will not be deformed due to the extrusion of the crushing plate 33;
[0047] Furthermore, in order to ensure that the screening plate 41 can fully screen, two telescopic mechanisms III 44 are fixedly connected to the crushing box 11, and the telescopic ends of the two telescopic mechanisms III 44 are respectively fixedly connected to the two connecting pipes 43;
[0048] Start the telescopic mechanism III 44, which can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III 44 drives the connecting pipe 43 to move, and the connecting pipe 43 drives the screening plate 41 to move, so that the screening plate 41 slides between the crushing box 11 and the conical cavity 12. The telescopic end of the telescopic mechanism III 44 reciprocates, constantly changing the position of the screening plate 41, achieving lateral shaking of the screening plate 41, and ensuring that the incineration slag can be effectively screened;
[0049] Furthermore, in order to further cool the incineration slag and extract the heat from the incineration slag;
[0050] The bottom of the conical cavity 12 is fixedly connected to a discharge cylinder 51, which is in communication with the conical cavity 12. A spiral shaft 52 is rotatably connected to the discharge cylinder 51. The interior of the spiral shaft 52 is hollowed out, and a motor for driving the spiral shaft 52 to rotate is fixedly connected to the discharge cylinder 51. The two ends of the spiral shaft 52 are rotatably connected to a connecting sleeve I 53 and a connecting sleeve II 54 respectively.
[0051] like Figure 2 As shown, the conical cavity 12 is connected to the interior of the discharge barrel 51, and then the incineration slag is crushed by the crushing mechanism 3 and screened by the screening plate 41 and enters the discharge barrel 51. The motor is started, and the motor is preferably a servo motor, as shown in FIG. Figure 10 As shown, a pulley is fixedly connected to the output shaft of the motor, and a pulley is fixedly connected to the spiral shaft 52. The pulley and the pulley are connected by a belt transmission. Then, when the output shaft of the motor starts to rotate, the spiral shaft 52 is driven to rotate. When the spiral shaft 52 rotates, a lateral component force is generated, which pushes the incineration slag in the discharge barrel 51 to move, so that the incineration slag moves from one side of the discharge barrel 51 to the other side, completing the discharge of the incineration slag.
[0052] At the same time, the heat exchange liquid pipeline is connected to the connecting sleeve II 54, and the connecting sleeve I 53 is close to the side where the incineration slag enters the discharge barrel 51. Since the temperature of the incineration slag just entering the discharge barrel 51 is relatively high, in order to ensure that the temperature of the incineration slag is reduced to a specified level when it is discharged from the discharge barrel 51, the liquid enters the spiral shaft 52 from the side of the connecting sleeve II 54, and heat exchange is carried out between the spiral shaft 52 and the incineration slag. After the heat exchange, since the temperature of the incineration slag just entering the discharge barrel 51 is relatively high, when the liquid moves to the side of the connecting sleeve I 53, heat exchange can still be carried out between the incineration slag and the liquid. Moreover, since the length of the discharge barrel 51 is relatively long, long-distance heat exchange can be carried out, thereby achieving sufficient cooling of the incineration slag and full utilization of the residual heat in the incineration slag.
