DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] Example 1: Reference Figures 1-6 A water-cooled sealed head for a rotary kiln includes: a sealing tube 1, a cold water jacket 2, a water inlet pipe 3 and a water outlet pipe 4. A heat conduction cavity is opened in the sealing tube 1, and the cold water jacket 2 is connected to the side wall of the sealing tube 1. The top end of the cold water jacket 2 is connected to the end of the water inlet pipe 3, and the bottom end of the cold water jacket 2 is connected to the end of the water outlet pipe 4.

[0027] The principles and beneficial effects of the above scheme are:

[0028] A cold water jacket 2 is installed on the side wall of the sealing tube 1. The cold water jacket 2 is supplied with water through the water inlet pipe 3 and drained through the water outlet pipe 4. The cold water is kept flowing inside the cold water jacket 2 at all times, which is convenient for cooling the structure. By simplifying the arrangement of components, the compactness of the structure is improved, the heat dissipation effect of the sealing head is increased, and its service life is extended.

[0029] Example 2: Reference Figures 1-6 The water inlet pipe 3 includes: a spiral tube 5, a rubber tube 6 and a metal tube 7. The cold water jacket 2 is provided with a spiral tube 5, the bottom end of the spiral tube 5 is placed inside the cold water jacket 2, the threaded section of the spiral tube 5 is arranged outside the cold water jacket 2, and is threadedly connected to the inner wall of the end of the rubber tube 6, and the other end of the rubber tube 6 is connected to the end of the metal tube 7.

[0030] A cavity is provided inside the cold water jacket 2 .

[0031] The water outlet pipe 4 includes: a spiral tube 8 and a metal tube 9. The spiral tube 8 is installed at the bottom of the cold water jacket 2. The top of the spiral tube 8 is placed inside the cold water jacket 2. The threaded section of the spiral tube 8 is placed outside the cold water jacket 2 and is threadedly connected to the inner wall of the end of the metal tube 9.

[0032] The water inlet end of the metal pipe 2 9 is connected to the water supply mechanism.

[0033] The principles and beneficial effects of the above scheme are:

[0034] The threaded section of the spiral tube 5 is threadedly connected to the inner wall of the end of the rubber tube 6, which improves the stability of the installation of the rubber tube 6. The threaded section of the spiral tube 8 is threadedly connected to the inner wall of the end of the metal tube 9, which improves the stability of the installation of the metal tube 9. The metal tube 9 increases the efficiency of drainage for the cold water jacket 2.

[0035] Example 3: Reference Figures 1-6 The metal tube 2 9 is provided with an oil storage shell 10, the oil storage cavity of the oil storage shell 10 is filled with hydraulic oil, the side wall of the oil storage shell 10 is connected to the end of the guide tube 11, and the guide tube 11 and the piston 12 are slidingly sealed.

[0036] One side of the piston 12 is connected to the end of a connecting rod 13 , and the connecting rod 13 is slidingly sealed with the guide tube 11 . The other end of the connecting rod 13 away from the guide tube 11 is equipped with the end of a rack 15 .

[0037] The connecting rod 13 is provided with a mounting plate, which is arranged outside the guide tube 11 . One side of the mounting plate is connected to the other end of the guide tube 11 via a spring 14 .

[0038] The rack 15 is slidably connected to the top of the metal tube 2 9 , and the rack 15 is meshed with a gear 16 , which is mounted on the rotating shaft.

[0039] The principles and beneficial effects of the above scheme are:

[0040] When the temperature of the water discharged from the metal tube 2 9 is high, the hydraulic oil in the oil reservoir 10 absorbs heat, causing its volume to expand. The expanded hydraulic oil pushes the piston 12 to move away from the oil reservoir 10, causing the connecting rod 13 and the rack 15 to move synchronously. The spring 14 is stretched, and the rack 15 is slidably connected to the top of the metal tube 2 9. Therefore, when the rack 15 is extended, its movement stability is guaranteed.

[0041] When the temperature of the water discharged from the metal tube 29 is low, the hydraulic oil in the oil storage shell 10 dissipates heat, thereby shrinking its volume. The shrinking hydraulic oil pushes the piston 12 to move toward the oil storage shell 10, and the connecting rod 13 and the rack 15 move synchronously. The spring 14 is compressed, and the rack 15 is slidably connected to the top of the metal tube 29. Therefore, the stability of the movement of the rack 15 is guaranteed when it is recovered.

[0042] Example 4: Reference Figures 1-6 The rotating shaft is rotatably connected to the steering housing 17, the steering housing 17 is installed on the metal tube 29, and the end of the rotating shaft placed in the steering housing 17 is connected to the adjusting column 18.

[0043] The adjusting column 18 is rotatably sealed with the steering housing 17 , and an adjusting hole 19 is opened on the adjusting column 18 , and the adjusting hole 19 is in conduction with the metal pipe 2 9 .

[0044] The axis of the regulating hole 19 is arranged at an angle to the axis of the metal pipe 9 , and the water inlet end of the regulating hole 19 is arranged toward the spring 14 .

[0045] The principles and beneficial effects of the above scheme are:

[0046] When the temperature of the sealed tube 1 is too high, the temperature of the cold water jacket 2 rises synchronously, and when the rack 15 extends, the gear 16 meshing with it rotates clockwise, and the rotating shaft and the adjusting column 18 rotate clockwise synchronously. The conduction area between the water inlet end of the adjusting hole 19 and the metal pipe 2 9 increases, and the amount of cold water entering the cold water jacket 2 increases. The mechanism can adjust independently to avoid overheating of the device; when the temperature of the sealed tube 1 decreases, the temperature of the cold water jacket 2 decreases synchronously, and when the rack 15 contracts, the gear 16 meshing with it rotates counterclockwise, and the rotating shaft and the adjusting column 18 rotate counterclockwise synchronously, and the conduction area between the water inlet end of the adjusting hole 19 and the metal pipe 2 9 decreases, and the amount of cold water entering the cold water jacket 2 decreases, which can save water resources and prevent the operation of the device from being affected by too low temperature.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
