Embodiment 1

[0022] Please refer to Figures 1-5, the utility model provides a technical solution: a high-strength three-tooth roll crusher for hot ore, which includes a crushing box 11, an upper roll 18 and a lower roll 16. The upper roll 18 and the lower roll 16 are respectively installed in the crushing box 11, and the lower roll 16 is arranged below the upper roll 18. The upper roll 18 is used for primary crushing. After the large materials are crushed, they fall onto the lower roll 16 for secondary crushing. Fixed bearing seats 3 are respectively arranged on the front side and the rear side of the lower part of the crushing box 11. A movable bearing seat 4 is arranged on one side of the fixed bearing seat 3. The movable bearing seat 4 is slidably connected with the crushing box 11. A slideway can be arranged on the side of the crushing box 11, and the movable bearing seat 4 is in sliding contact with the slideway. Other ways can also be used to achieve sliding contact. The lower roll 16 includes a movable roll and a fixed roll. The movable roll is installed between the movable bearing seats 4, and the fixed roll is installed between the fixed bearing seats 3. Through this structure, the lower roll 16 can be protected from hard contact with materials during crushing, playing a buffering and protective role. The upper roll 18 is installed in the crushing box 11 through an upper bearing seat 19. The water inlets of the upper bearing seat 19, the fixed bearing seat 3 and the movable bearing seat 4 are respectively connected with a water inlet pipeline 12, and the water outlets of the upper bearing seat 19, the fixed bearing seat 3 and the movable bearing seat 4 are respectively connected with a drainage pipeline 8. This cooling water circulation system can cool the bearings and prevent the bearings from failing due to long-term high-temperature operation. Temperature sensors are also respectively arranged in the bearing seats to detect the bearing temperature during the operation of the roll crusher, ensuring the normal operation of the roll crusher.

[0023] In this embodiment, a movable plate 6 is arranged on one side of the movable bearing seat 4. The movable plate 6 is slidably connected with the side of the crushing box 11. A spring 5 is arranged between the movable bearing seat 4 and the crushing box 11. This spring 5 enables the movable roll to buffer the external force generated during the crushing process. The outer end of the movable plate 6 is hinged with a movable force arm 9. The movable force arm 9 is arranged in a bent structure. The bent part of the movable force arm 9 is hinged with the side of the crushing box 11. A counterweight 13 is arranged on the movable force arm 9. By increasing the counterweight 13, the movable force arm 9 can move along with the movement of the movable bearing seat 4, so that the elastic force of the spring 5 remains constant. Compared with the spring 5 directly fixed on the crushing box 11, this structure can more effectively maintain the constant pressure between the movable roll and the fixed roll, ensure the stable crushing effect, and avoid the reduction of the crushing efficiency caused by the change of the gap.

[0024] In this embodiment, a reinforcing plate 22 is arranged on the inner wall of the crushing box 11. The reinforcing plate 22 is used to protect the crushing box 11 and increase the structural strength at the same time. An insulating layer 23 is arranged between the reinforcing plate 22 and the crushing box 11. Through the insulating layer 23, the heat transfer is reduced, so as to protect the crushing box 11 from the heat of high-temperature materials and improve the service life of the equipment in a high-temperature environment.

[0025] In this embodiment, crushing teeth 15 are evenly arranged in the circumferential direction of the upper roller 18. Reinforcing ribs 14 are arranged on the side surfaces of the crushing teeth 15. Fixed teeth one 20 and fixed teeth two 21 are respectively arranged on both side surfaces of the upper roller 18. Through the cooperation of the crushing teeth 15 of the upper roller 18 with the fixed teeth one 20 and the fixed teeth two 21, large-particle materials can be preliminarily crushed; convex teeth 17 are evenly arranged in the circumferential direction of the lower roller 16. The materials are crushed again through the cooperation of the convex teeth 17 on the moving roller and the fixed roller; this double-crushing structure can effectively improve the crushing efficiency, make the control of the particle size of the materials more precise, and the crushing effect better.

[0026] In this embodiment, a base 2 is arranged at the lower end of the crushing box 11. A belt drive assembly one 1 is arranged on the base 2. The belt drive assembly one 1 is used to drive the upper roller 18 and the fixed roller; a belt drive assembly two 10 is arranged on the side surface of the crushing box 11. The belt drive assembly two 10 is used to drive the moving roller. The belt drive assembly is a conventional transmission contact, usually composed of a speed reducer, a driving pulley, a driven pulley and a belt; a pressing wheel 7 is arranged on the movable force arm 9. The pressing wheel 7 is used to press the belt to ensure stable power transmission and prevent the problem of unstable power transmission caused by belt loosening, and improve the overall operation efficiency of the equipment.

[0027] Working principle: After the materials enter the crushing box 11, they are first preliminarily crushed by the upper roller 18. The crushing teeth 15 of the upper roller 18 cooperate with the fixed teeth one 20 and the fixed teeth two 21 to crush the large-particle materials into materials with a smaller particle size; the materials after preliminary crushing fall into the lower roller 16 for secondary crushing. The lower roller 16 includes a moving roller and a fixed roller. The two crush the materials again through the meshing action of the convex teeth 17, so as to achieve more precise control of the particle size of the materials; in order to prevent the bearings from failing due to being in a high-temperature state for a long time, the crusher is equipped with a cooling water circulation system; the water inlets of the upper bearing seat 19, the fixed bearing seat 3 and the moving bearing seat 4 are respectively connected to the water inlet pipeline 12. After the cooling water enters the bearings, it cools the bearings, and the drainage is discharged through the water outlet through the drainage pipeline 8, thus forming a closed-loop cooling system; a temperature sensor is also arranged inside the bearing seat to detect the bearing temperature in real time. When the temperature exceeds the set threshold, the system automatically starts the cooling mechanism, thereby effectively preventing the bearing temperature from getting out of control and ensuring the stable operation of the equipment.

[0028] To prevent damage to the equipment due to hard contact between the moving roller and the fixed roller, a spring 5 is provided between the moving bearing seat 4 and the crushing box 11 in this device for buffer protection; when the material pressure changes, the moving bearing seat 4 can slide in the slideway on the side of the crushing box 11, and at the same time, the movable force arm 9 hinged to it drives the counterweight 13 to move, so as to keep the elastic force of the spring 5 constant, ensure the stable pressure between the moving roller and the fixed roller, and improve the crushing effect; a reinforcing plate 22 is provided on the inner wall of the crushing box 11, and the reinforcing plate 22 can enhance the structural strength of the crushing box, and at the same time, the heat insulation layer 23 provided between the reinforcing plate 22 can reduce heat transfer and avoid damage to the crushing box caused by heat; the equipment also ensures stable power transmission through the belt drive system, the belt drive assembly one 1 is used to drive the upper roller 18 and the fixed roller, and the belt drive assembly two 10 is used to drive the moving roller; to keep the tension of the belt and prevent the belt from loosening during power transmission, a pressing wheel 7 is provided on the movable force arm 9, and the pressing wheel 7 presses the belt, so as to further improve the power transmission stability of the crusher and realize the long-term efficient operation of the equipment.

[0029] The above shows and describes the basic principles, main features and advantages of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model has various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
