Therefore, solid waste can be added into the melting chamber 101 through the feed port 3, and then high-temperature steam is injected into the jacket layer 102 to melt the solid waste in the melting chamber 101, so that the waste is melted into liquid. After standing for a period of time, the impurities in the liquid can be settled to the bottom. In addition, a discharge pipe assembly 4 is installed on the outer wall of the melting chamber 101, and the clear material after melting is discharged through the discharge pipe assembly 4 for recovery, and the impurities settled to the bottom can be taken out later; In this embodiment, the discharge pipe assembly 4 is configured to have two discharge ports, and specifically, the two outlets are configured at different heights, wherein the high outlet is used to discharge clear materials, and the low outlet is used to discharge bottom impurities for tank cleaning.

[0019] More specifically, the discharge pipe assembly 4 includes a pipe 1 401 and a pipe 2 402, wherein the pipe 1 401 is arranged outside the melting chamber 101 and communicated with the inside of the melting chamber 101, and the other end of the pipe 1 401 passes through the jacket layer 102 and extends to the outside of the jacket layer 102, and the pipe 2 402 is arranged at the bottom of the melting chamber 101 and communicated with the inside of the melting chamber 101. It should be noted that the pipe 2 402 is arranged at the center of the bottom wall of the melting chamber 101 and is below the pipe 1 401; Considering that when the impurities settled on the bottom of the melting chamber 101 are discharged for tank cleaning, the impurities settled on the bottom will easily adhere to the bottom wall of the melting chamber 101, and the impurities are not cleaned thoroughly during tank cleaning. Therefore, a scraping assembly 5 is provided at the bottom of the melting chamber 101, and the impurities on the bottom wall of the melting chamber 101 can be scraped off by the scraping assembly 5 during tank cleaning, so that the adhered impurities are scraped to the same place and then discharged from the bottom pipe 2 402.

In addition, as Figure 5 and Figure 8As shown, one end of the spiral auger 12 shaft passes through the side wall of the discharge cover 7 and extends to the inside of the second tube 402, and the gear set 8 is provided to make the rotating shaft 501 and the shaft of the spiral auger 12 transmission connected. Specifically, a bevel gear 1 801 is fixedly sleeved on the outside of the rotating shaft 501 located at a section of the second tube 402, and a bevel gear 2 802 is fixedly provided on one end of the shaft of the spiral auger 12 that passes through the side wall of the discharge cover 7, and the bevel gear 2 802 is meshedly connected with the bevel gear 1 801, so that the rotating shaft 501 can drive the spiral auger 12 to rotate when it rotates; Therefore, through the above-mentioned arrangement, when it is necessary to clean the tank, the driving motor 552 is started to rotate the rotating shaft 501, and the rotating shaft 501 drives the scraper bar 502 to move to scrape the impurities on the bottom wall of the melting chamber 101, and the scraped impurities will fall into the interior of the receiving groove 503, and enter the interior of the discharge bin 504 through the receiving groove 503. At the same time, the rotating shaft 501 rotates through the gear set 8 to drive the spiral auger 12 to rotate, so that the impurities inside the discharge bin 504 can be transported toward the direction of pipe 2 402. The impurities inside the discharge bin 504 will enter the interior of pipe 2 402 through the opening at the bottom of the discharge cover 7 under the transportation of the spiral auger 12, and then be discharged through pipe 2 402.

[0021] Considering that the bottom wall of the melting chamber 101 is provided with a receiving groove 503, in order to prevent the melted material in the melting chamber 101 from being discharged from the receiving groove 503, the receiving groove 503 needs to be sealed before cleaning the tank; In this embodiment, if Figure 1 , Figure 4 ,picture, Figure 7-Figure 9 As shown, the rotating shaft 501 is specifically configured to include a sleeve 511 and an inner shaft 512 arranged inside the sleeve 511, wherein the inner shaft 512 is slidably inserted inside the sleeve 511, and the inner shaft 512 and the sleeve 511 are limited by a limiting strip 11, and the limiting strip 11 allows the inner shaft 512 to only slide axially and longitudinally inside the sleeve 511 but not to rotate circumferentially, the top end of the inner shaft 512 extends above the sleeve 511, and a sliding sealing treatment is performed between a top section of the inner shaft 512 and the sleeve 511, and the scraper strip 502 is fixedly arranged on a portion of the inner shaft 512 located outside the sleeve 511 The outer wall of the end, in addition, the second tube 402 is set to be two sections, and the end section is inclined, and one end of the sleeve 511 passes through the outer wall of the second tube 402 and extends to the bottom of the second tube 402, and the bottom end of the inner shaft 512 extends to the bottom of the sleeve 511, and a limit column 9 is fixedly set at one end of the inner shaft 512 located below the sleeve 511, and a spring 10 is set between the limit column 9 and the sleeve 511, and the spring 10 is sleeved on the outside of the inner shaft 512 to rebound the inner shaft 512 downward. It should be noted that the sleeve 511 is connected to the output end of the drive motor 552 through the belt drive group 553; like Figure 2 As shown, the scraper strip 502 is specifically configured as a connecting portion 521 and a scraping portion 522, wherein the connecting portion 521 is fixedly connected to the outer wall of the inner shaft 512, and the scraping portion 522 is arranged at the other end of the connecting portion 521, and the length of the scraping portion 522 is configured to extend from the outer circumferential wall of the tube 2 402 along the radial direction of the bottom wall toward the inner wall of the inner circle of the melting chamber 101, the thickness of the scraping portion 522 is greater than the thickness of the connecting portion 521, and the lower half of the scraping portion 522 is plugged into the receiving groove 503. The scraper portion 522 and the receiving groove 503 are matched, and the plug-in portion of the scraper portion 522 and the receiving groove 503 is matched with a sliding seal, so that the scraper portion 522 can be plugged into the receiving groove 503 to seal the receiving groove 503, thereby preventing the melted material in the melting chamber 101 from entering the discharge bin 504, and the lower end surface of the connecting portion 521 is fitted with the top surface of the pipe 402 to limit the scraper portion 522, and the plug-in connection between the scraper portion 522 and the receiving groove 503 is controlled by the spring 10. In addition, Figure 3 As shown, a slope is provided on one side of the groove wall of the receiving groove 503, so that when the rotating shaft 501 rotates, the scraping part 522 can be guided by the slope to enter the upper part of the bottom wall of the melting chamber 101 to perform scraping work.

[0022] Through the above arrangement, under normal conditions, when the scraper portion 522 moves to the receiving groove 503, the inner shaft 512 can be moved downward by the rebound of the spring 10, and then the scraper portion 522 moves downward and is inserted into the receiving groove 503 to limit the receiving groove 503. When the tank cleaning work is required, the driving motor 552 is started, and the rotating shaft 501 can drive the scraper portion 522 to move in the direction of the slope, and then the slope makes the scraper portion 522 move to the top of the bottom wall of the melting chamber 101, and the inner shaft 512 moves upward to compress the spring 10, and then the scraper portion 522 scrapes the impurities on the bottom wall to be cleaned to the receiving groove 503 and enter the discharge bin 503 from the receiving groove 503. 04, and at the same time, the rotating shaft 501 rotates through the gear set 8 to drive the spiral auger 12 to rotate, so that the impurities inside the discharge bin 504 can be transported toward the direction of the second pipe 402.

[0023] The principle of the present invention is as follows: the present invention adds solid waste into the melting chamber 101 through the feed port 3, and then injects high-temperature steam into the inside of the jacket layer 102 to melt the solid waste inside the melting chamber 101, so that the waste is melted into liquid. After standing for a period of time, the impurities inside the liquid can sink to the bottom, and then the clear material is discharged through the pipe 401. When the tank needs to be cleaned, the drive motor 552 is started, and the rotating shaft 501 can drive the scraper part 522 to move in the direction of the slope, and then the scraper part 522 is moved to the top of the bottom wall of the melting chamber 101 through the slope, and the inner shaft 512 moves up to compress the spring 10, and then the impurities on the bottom wall are cleaned and stored under the scraping of the scraper part 522. The impurities in the discharge bin 504 can be transported toward the direction of the second pipe 402. The impurities in the discharge bin 504 can enter the second pipe 402 through the opening at the bottom of the discharge cover 7 under the transportation of the spiral auger 12, and then be discharged through the second pipe 402. When the scraping work needs to be stopped again, when the scraping part 522 moves to the receiving groove 503, the inner shaft 512 will move downward under the action of the spring 10, and the limiting column 9 is set at the bottom of the kettle body 1, which can facilitate the staff to judge that the scraping part 522 moves to the inside of the receiving groove 503 according to the downward movement of the limiting column 9, and then stop the driving motor 552.
