When normal heating is performed, the feed port 4 and the discharge port 3 are in an open state, and at this time, the arc plate 7 and the heating cylinder 2 are in a closed state. The inner wall of the heating cylinder 2 does not contact, the hemispherical end of the sleeve 11 is against the connection between the arc block 20 and the semi-spherical body 13, and the telescopic spring 25 is in a squeezed state. When the motor 5 works, the arc plate 7 can be driven to move, and the water in the heating cylinder 2 can be stirred, so that the water flow in the heating cylinder 2 can be heated more evenly. After the heating is completed, when it is necessary to regularly clean the scale formed on the inner wall of the heating cylinder 2, the semi-spherical body 13 is controlled by rotating the handle 21 to seal the feed port 4. During the movement of the semi-spherical body 13, the squeezed telescopic spring 25 is expanded to push the sleeve 11 to move, so that the hemispherical end of the sleeve 11 is against the arc block 20 (such as Fig.11 In the process of moving, the sleeve 11 can push the arc plate 7 to contact the inner wall of the heating tube 2 by limiting the conical plate 30 and the heating tube 2 (the motor 5 rotates an integer number of times each time, and when the arc plate 7 contacts the inner wall of the heating tube 2, as shown in FIG. Figure 2, one of the arc plates 7 can seal the discharge port 3, which is convenient for the subsequent immersion of the inside of the heating cylinder 2). At this time, the rotating cylinder 19 is connected to the inside of the heating cylinder 2 through the liquid outlet hole 27, the connecting hole 29 and the small hole 31, and the heating cylinder 2 can be soaked by adding medicine through the medicine feeding pipe 9. After the soaking is completed, the motor 5 can control the movement of the arc plate 7 to facilitate the cleaning of the inner wall of the heating cylinder 2 after soaking. The rotation of the arc block 20 and the semi-spherical body 13 can push the sleeve 11 to move while realizing the sealing of the feed port 4, so that the arc plate 7 contacts the inner wall of the heating cylinder 2 to seal the discharge port 3. After the arc plate 7 contacts the inner wall of the heating cylinder 2, it is convenient for the subsequent cleaning work. The rotation of the arc block 20 and the semi-spherical body 13 can release the seal of the feed port 4, and at the same time, through the cooperation of the telescopic spring 25, the arc plate 7 is separated from the inner wall of the heating cylinder 2, which can be used for heating and stirring.

[0032] As a further technical solution of the present invention, the rotating member includes two connecting rods 26 arranged in the opening 16, one of the connecting rods 26 is slidably connected to the opening 16, and the other is fixedly connected to the opening 16. The rotating drum 19 is located in the opening 16 and is rotatably installed with a gear 17. The gear 17 has sawtooth bars 14 meshingly connected on both sides. The two sawtooth bars 14 are respectively fixedly connected to the two connecting rods 26. The outer end of the connecting rod 26 is fixedly connected with a scraper 15. When heating and stirring are performed, the scraper 15 does not contact the corresponding conical plate 30 or the inner wall of the heating tube 2. After the dosing and soaking of the heating tube 2 is completed, when the scale is cleaned, the scraper 15 can be driven to contact the corresponding conical plate 30 or the inner wall of the heating tube 2 in the process of controlling the movement of the sleeve 11. After the soaking is completed, the scraper 15 is controlled to move, which is convenient for cleaning the soaked conical plate 30 or the heating tube 2.

[0033] As a further technical solution of the present invention, a plurality of blades 28 for cleaning the circular hole 33 are installed on the outside of the sleeve 11. When cleaning scale, in the process of controlling the movement of the sleeve 11, the blades 28 are driven to move and contact the inner wall of the circular hole 33, thereby facilitating the cleaning of the inner wall of the circular hole 33.

[0034] Working principle: During normal heating, the feed port 4 and the discharge port 3 are in an open state, at which time the arc plate 7 does not contact the inner wall of the heating tube 2, the scraper 15 does not contact the corresponding conical plate 30 or the inner wall of the heating tube 2, the telescopic spring 25 is in an extruded state, the liquid outlet 27 and the connecting hole 29 are in a misaligned state, and the small hole 31 is sealed by the connecting tube 12;

[0035] By using the electromagnetic coil 6, the heating cylinder 2 can heat the water flowing inside it. The conical plate 30 can slow down the flow rate of water in the heating cylinder 2 to increase the time the water stays in the heating cylinder 2 and improve the heating efficiency. The conical plate 30 is directly connected to the inner wall of the heating cylinder 2. Through heat conduction, the water flow in contact with the conical plate 30 can also be heated.

[0036] At the same time, the motor 5 is started to drive the rotating drum 19 to rotate, and the rotating drum 19 drives the sleeve 11 to rotate, so that the arc plate 7 moves to stir the water in the heating drum 2, so that the water flow in the heating drum 2 can be heated more evenly;

[0037] After the heating is finished, it is necessary to regularly clean the scale formed on the inner wall of the heating cylinder 2. At this time, the handle 21 is turned upward, the handle 21 drives the rectangular rod 23 to rotate, the rectangular rod 23 drives the round rod 22 to rotate, and the round rod 22 drives the semi-circular sphere 13 to rotate half a circle to seal the feed port 4. During the movement of the semi-circular sphere 13, the squeezed telescopic spring 25 expands to push the sleeve 11 to move, so that the hemispherical end of the sleeve 11 abuts against the arc block 20 (such as Fig.11 The position relationship of the liquid outlet 27 is made to communicate with the connecting hole 29. During the movement of the sleeve 11, the arc plate 7 can be pushed to contact the inner wall of the heating tube 2 by limiting the conical plate 30 and the heating tube 2 (the motor 5 rotates an integer number of times each time, and when the arc plate 7 contacts the inner wall of the heating tube 2, as shown in FIG. Figure 2 , one of the arc plates 7 can seal the discharge port 3, which is convenient for the subsequent immersion of the inside of the heating cylinder 2), the arc plate 7 moves to make the round tube 10 slide on the connecting tube 12, and the small hole 31 is opened (the sleeve 11 drives the connecting tube 12, and the connecting tube 12 drives the round tube 10 to move, and the conical plates 30 at both ends of the arc plate 7 and the inner walls of the two ends of the heating cylinder 2 are limited, which will make the arc plate 7 move to contact the inner wall of the heating cylinder 2, and at the same time drive the round tube 10 to slide on the connecting tube 12, and the round tube 10 and the connecting tube 12 slide and unfold, so that the small hole 31 sealed by the connecting tube 12 is opened), at this time, the rotating drum 19 is connected with the inside of the heating cylinder 2 through the liquid outlet hole 27, the connecting hole 29 and the small hole 31, and the heating cylinder 2 can be soaked with medicine through the medicine inlet pipe 9 to remove scale. After the soaking is completed, the scale is basically dissolved;

[0038] During the movement of the sleeve 11, the sawtooth bar 14 fixedly connected thereto can be driven to move, and through the cooperation between the gear 17 and the sawtooth bar 14, the scraper 15 can be driven to contact the corresponding conical plate 30 or the inner wall of the heating tube 2;

[0039] At this time, the motor 5 is started to control the movement of the arc plate 7 and the scraper 15, so as to facilitate the cleaning of the conical plate 30 and the inner wall of the heating cylinder 2 after soaking;

[0040] In the present application, the rotation of the arc block 20 and the semi-sphere 13 can push the sleeve 11 to move so that the arc plate 7 contacts the inner wall of the heating tube 2 to seal the discharge port 3 while achieving the sealing of the feed port 4. The contact between the arc plate 7 and the inner wall of the heating tube 2 facilitates subsequent cleaning work. The rotation of the arc block 20 and the semi-sphere 13 can release the seal of the feed port 4 while, through the cooperation of the telescopic spring 25, the arc plate 7 is separated from the inner wall of the heating tube 2, which can be used for heating and stirring.
