[0004] In the existing quenching device, the pipe is used as a guide component to guide the solid waste slag from the combustion chamber to the quenching chamber. However, the pipe is limited by its cross-sectional area, and the solid waste slag will inevitably come into contact with the pipe. Thus, in the process of continuously guiding the solid waste slag to the quenching chamber, the solid waste slag will block the pipe. Therefore, a quenching device for industrial solid waste roasting is proposed. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] like Figure 1 and Figure 2 As shown, a quenching device for industrial solid waste roasting in this embodiment is used to collect and cool the industrial solid waste slag in the combustion chamber of the existing roasting device. The quenching device is arranged at the discharge port of the combustion chamber of the roasting device. The industrial solid waste roasting device includes a quenching chamber 1, a quenching ring 2, a slag discharge pipe 3, a dredging structure 4 and a pressure regulating structure 5, wherein the quenching ring 2 is fixed to the quenching chamber 1 by bolts and connected to the combustion chamber of the existing roasting device, and the slag discharge pipe 3 is welded and arranged at the bottom of the quenching ring 2. In this way, when the solid waste slag passes through the inside of the quenching ring 2, the quenching ring 2 sprays quenching water to the inner wall of the slag discharge pipe 3, so that the quenching water is evenly distributed on the inner wall of the slag discharge pipe 3, thereby forming a liquid film. Under the influence of the liquid film, the solid waste slag can be cooled and the slag discharge pipe 3 is protected. The dredging structure 4 is located in the quenching chamber 1.

[0028] As for the dredging structure 4 and the pressure regulating structure 5 as the focus of this application, first of all, Figure 3 and 4 As shown, the dredging structure 4 includes a slide 41, a dredging piece 42 and a spring 43, wherein the slide 41 is welded to the outside of the slag discharge pipe 3, and the dredging piece 42 is slidably connected to the slide 41 through the spring 43, and one side of the spring 43 is fixed to the inner wall of the slide 41. In the design, the spring 43 is used to prevent the dredging piece 42 from completely falling out of the slide 41 and to allow the dredging piece 42 to be reset. The length of the dredging piece 42 is preferably equal to the diameter of the slag discharge pipe 3.

[0029] Secondly, the pressure regulating structure 5 is used to adjust the internal air pressure in the slide cylinder 41 to change the position of the dredging member 42, so that the dredging member 42 can complete the dredging work. Figure 3The pressure regulating structure 5 specifically includes an air pump 51, an air ring 52 and an exhaust pipe 53, wherein the air pump 51 is preferably fixed to the outside of the quenching chamber 1 by bolts. For example, a machine base is welded on the outside of the quenching chamber 1, and the air pump 51 is fixed to the machine base by bolts. The air ring 52 is fixed to the inner wall of the quenching chamber 1, and the air pump 51 and the slide 41 are both connected to the air ring 52. In this way, when the air pump 51 inflates the air ring 52, the inflated gas can enter the slide 41, thereby changing the air pressure in the slide 41, and under the influence of the air pressure, the clearing piece 42 in the slide 41 can move toward the center of the slag discharge pipe 3. In addition, the exhaust pipe 53 is welded on the air ring 52. It should be noted that this exhaust pipe 53 is connected to the outside world, and the exhaust pipe 53 has a valve body for controlling its opening and closing, and the valve body is preferably a solenoid valve.

[0030] It should be noted that a connecting pipe 54 is fixedly provided between the air pump 51 and the air ring 52 for completing the connection between the air pump 51 and the air ring 52, and a connecting pipe 55 is fixedly provided between the air ring 52 and the slide cylinder 41 for completing the connection between the air ring 52 and the slide cylinder 41. In addition, a trumpet-shaped discharge port is provided at the bottom of the slag discharge pipe 3, which is narrow at the top and wide at the bottom, so that the outlet of the slag discharge pipe 3 can be discharged more easily.

[0031] In this way, after the air pump 51 finishes inflating the air ring 52, the valve body is opened. According to the law of air pressure balance, part of the gas in the slide cylinder 41 and the air ring 52 will flow out from the exhaust pipe 53, and the air pressure in the slide cylinder 41 and the air ring 52 will also be restored, and the spring 43 will allow the clearing piece 42 to move back to its original position. In the process of cyclically starting and stopping the air pump 51 and switching the valve body, the clearing piece 42 will cyclically move back and forth to ensure that the slag discharge pipe 3 is not blocked, thereby ensuring that the quenching chamber 1 can normally receive the solid waste slag flowing out of the combustion chamber.

[0032] In order to speed up the dredging, the number of the slide cylinders 41 is not less than one group, and the slide cylinders 41 are arranged obliquely. Different oblique directions of the slide cylinders 41 will produce different dredging effects.

[0033] For example, in one embodiment, Figure 2 and 3 As shown, the side of the slide tube 41 away from the slag discharge pipe 3 is tilted upward. At this time, the clearing member 42 will move away from the quenching ring 2 during the displacement. In this way, the clearing member 42 will only clear the inner side of the slag discharge pipe 3.

[0034] In another embodiment, if Figure 5 As shown, the side of the slide 41 away from the slag discharge pipe 3 is tilted downward. At this time, the clearing member 42 will move close to the quenching ring 2, so that the clearing member 42 can clear the inner side of the quenching ring 2 and the inner side of the slag discharge pipe 3 at the same time.

[0035] It should be noted that, although the inclination directions of the slide cylinders 41 are designed differently, in the above two embodiments, there are four groups of slide cylinders 41 , and the four groups of slide cylinders 41 are distributed in a circular array and surround the outer side of the slag discharge pipe 3 .

[0036] Working principle:

[0037] When the air pump 51 is started to inflate, the air will be guided through the connecting pipe 54, and the air ring 52 will obtain additional gas. After being guided through the connecting pipe 55, the additional gas will flow out of each slide 41. In this way, the air pressure in the slide 41 will be changed. When the air pressure in the slide 41 changes, the clearing piece 42 in the slide 41 will be able to move toward the center of the slag discharge pipe 3 under the influence of the air pressure. After the air pump 51 is inflated, the valve body is opened, and part of the gas in the slide 41 and the air ring 52 will flow out from the exhaust pipe 53. The air pressure in the slide 41 and the air ring 52 will also be restored, and the spring 43 will allow the clearing piece 42 to move back to its original position. In the process of cyclically starting and stopping the air pump 51 and switching the valve body, the clearing piece 42 will cyclically move back and forth to ensure that the slag discharge pipe 3 is not blocked, thereby ensuring that the quenching chamber 1 can normally receive the solid waste slag flowing out of the combustion chamber.

[0038] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
