[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-5 A slag cooler slag discharge pipe slag leakage device is shown.

[0021] Finally, it should be noted that the above is only a preferred embodiment of the utility model, including an insulated slag pipe 2 and an electric insulated ash valve 5 arranged at the bottom of the insulated slag pipe 2, a manual insulated ash valve 6 for slag discharge is arranged at the bottom of the electric insulated ash valve 5, and an insulated cone bucket 1 for slag discharge is arranged at the bottom of the manual insulated ash valve 6, and a control mechanism for controlling slag discharge is arranged inside the electric insulated ash valve 5, and the control mechanism includes a first connecting pipe 506 and an adjusting plate 501, and the first connecting pipe 506 is provided with a first connecting pipe 506 and an adjusting plate 501. The through pipe 506 is arranged at the bottom of the insulated slag pipe 2, and the adjusting plate 501 is inserted and connected to the inner wall of the first connecting pipe 506. The inner wall of the first connecting pipe 506 is inserted and connected with a cooling material 503 for cooling the ash. It should be noted that the insulated cone barrel 1 adopts a double-layer insulation structure, the outer tube is a 10mm steel pipe, and the outer surface temperature is ≤150℃ (the insulation thickness can be adjusted as needed to reduce the surface temperature), and a slag poking device is provided on the side of the rare earth alloy cone section at the lower end of the insulated metal expansion joint, which is convenient for clearing the expansion joint and the alloy cone section when slag is blocked.

[0022] The inner wall of the cooling material 503 is interspersed with a conveying pipe 502 for transporting ash, and the inner wall of the conveying pipe 502 is interspersed with the outer wall of the adjusting plate 501, and a fixing bolt 505 is provided between the conveying pipe 502 and the cooling material 503 for connecting and fixing the two, and the first connecting pipe 506 is fixedly connected to the first connecting rod 504 on the side away from the insulated slag pipe 2.

[0023] The manual insulated ash valve 6 includes a second connecting pipe 604 and a second connecting rod 602 . The second connecting pipe 604 is arranged on the top of the insulated cone barrel 1 , and the second connecting rod 602 is fixedly connected to the outer wall of the second connecting pipe 604 .

[0024] The outer wall of the insulated slag pipe 2 is provided with a limiting guide rod 4 for positioning the insulated slag pipe 2, and the top of the limiting guide rod 4 is fixedly connected with a support bracket 3 for fixing the limiting guide rod 4. It should be noted that the insulated slag pipe 2 adopts a double-layer pipe structure design, the inner pipe is made of high-temperature, heat-resistant and wear-resistant rare earth cast steel material, the upstream and downstream pipe sections connected to the inner pipe adopt a standard socket-type interface, and the upstream and downstream pipe sections connected to the outer pipe are connected by flange welding.

[0025] It should be explained that the manual insulated ash valve 6 and the electric insulated ash valve 5 are designed as a double-layer valve body structure with clear division of labor. The inner valve body only forms an ash channel, which is wear-resistant and high-temperature resistant but cannot withstand the reverse force applied by external equipment, while the outer valve body with low temperature and high strength withstands external forces. The valve core material is made of rare earth cast steel that is resistant to high-temperature deformation. The inner valve body has a "squeezing" anti-slag jamming design, and a slag-free space can be formed in the valve body cavity. When the valve plate is closed, the ash at the front end and both sides of the valve plate can be easily squeezed into the slag-free space without allowing ash particles to block or jam the valve plate, thereby increasing the service life of the equipment.

[0026] A slag discharge conduit 202 for slag discharge is inserted and connected inside the insulated slag pipe 2, and the outer wall of the slag discharge conduit 202 is provided with an insulating material 201 for cooling the ash, and a supporting assembly 203 for supporting the slag discharge conduit 202 is provided between the slag discharge conduit 202 and the insulated slag pipe 2. It should be noted that the slag discharge conduit 202 uses highly heat-resistant and wear-resistant rare earth cast steel material with a temperature resistance of over 1100°C, no thermal deformation occurs at high temperatures, the service life is greatly extended, the insulation effect is good, there is no red tube phenomenon, and the surface wall temperature is lower than 150°C. Due to its unique internal structure, the problem of uneven thermal expansion of the boiler can be avoided.

[0027] An opening 603 for ash to pass through is provided inside the second connecting pipe 604 , and a rocker 601 is provided on a side of the second connecting rod 602 away from the second connecting pipe 604 .

[0028] During actual use, when the ash needs to be discharged, it is only necessary to operate the motor on one side of the electric insulated ash valve 5 and the rocker 601 on one side of the manual insulated ash valve 6 to control the position of the adjusting plate 501, so that the ash inside the insulated slag pipe 2 can be discharged downward. The cooling material 503 and the insulating material 201 can be used to cool the ash well and play a good insulating role at the same time, so that the ash can be discharged through the bottom of the insulated cone barrel 1. The overall operation is simple and quick.

[0029] It is not used to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
