[0022] The present invention provides the following embodiments Embodiment 1 The embodiment of the present invention provides a boiler wood block separation automatic cleaning device, as Figures 1-4 shown, including: a cleaning mechanism 1, including an outlet pipe body 2, a cover plate 3 provided on the front of the outlet pipe body 2, a rotating rod 4 provided at the lower end of the front side of the inner cavity of the outlet pipe body 2, a metal plate 5 provided on the rear side of the surface of the rotating rod 4, a connecting rod 6 provided at the left end of the surface of the rotating rod 4 and outside the outlet pipe body 2, and a connecting handle 7 provided at the lower left side of the connecting rod 6; including a limiting mechanism 8, the limiting mechanism 8 includes a fixed block 9 provided at the lower end of the left side of the outlet pipe body 2, a positioning block 10 provided on the surface of the fixed block 9, a connecting seat 11 provided at one end of the positioning block 10 away from the fixed block 9, a movable column 12 provided in the inner cavity of the connecting seat 11, a connecting block 13 provided at the rear side of the connecting rod 6, a movable plate 14 provided at the rear end of the movable column 12, and a spring 15 provided at the rear side of the movable plate 14.

[0023] The working principle and beneficial effects of the above technical solution are as follows: By setting the rotating rod 4, it is used to drive the metal plate 5 to displace. By setting the metal plate 5, it is used to clean the sundries in the inner cavity of the outlet pipe body 2. By setting the connecting handle 7, it is convenient for the user to drive the rotating rod 4 to rotate through the connecting rod 6, and then drive the metal plate 5 to displace, so as to clean the sundries in the separator grille. The operation is simple and convenient, saving time, and also avoiding cold air from leaking into the powder-making system, reducing the risks to personnel and equipment. By setting the fixed block 9, the positioning block 10 and the connecting block 13, they are used to cooperate with the movable column 12, the movable plate 14 and the spring 15 to limit the connecting rod 6, and then reset the metal plate 5, avoiding the need to manually reset the metal plate 5 after cleaning the sundries, which has the effect of saving effort. When in use, when there are sundries in the grille of the inner cavity of the outlet pipe body 2, open the cover plate 3, pull the connecting handle 7 to displace backward and upward. The connecting handle 7 drives the connecting rod 6 to displace in an arc. The connecting rod 6 drives the connecting block 13 to displace backward, and at the same time drives the rotating rod 4 to rotate. The rotating rod 4 drives the rear end of the metal plate 5 to displace upward, driving the sundries in the grille of the inner cavity of the outlet pipe body 2 upward. The metal plate 5 is inclined at an angle, and the sundries slide along the surface of the metal plate 5 and fall outside the outlet pipe body 2 through the cover plate 3. During the process of the connecting block 13 displacing backward, it drives the movable column 12 to displace into the inner cavity of the connecting seat 11. The movable column 12 drives the movable plate 14 to displace. The movable plate 14 drives the spring 15 to displace. The spring 15 deforms under force. When the sundries in the grille of the inner cavity of the outlet pipe body 2 are cleaned and the connecting handle 7 is released, the reset elastic force generated by the spring 15 pushes the movable plate 14 to displace. The movable plate 14 drives the movable column 12 and the connecting block 13 to displace, and then drives the metal plate 5 to reset through the connecting rod 6 and the rotating rod 4, and the cleaning can be completed. The present invention can automatically identify, separate and clean the wood blocks in the boiler, improve the combustion efficiency of the boiler, reduce the working intensity of manual cleaning, and ensure the safe and stable operation of the boiler.

[0024] Embodiment 2 On the basis of Embodiment 1, as Figures 1-4 shown, the connecting seat 11 includes a limiting groove 16, which is arranged at the top and bottom of the inner cavity of the connecting seat 11, and a limiting block 17 arranged in the inner cavity of the limiting groove 16; The front surface of the outlet pipe body 2 is hinged to the cover plate 3 through a hinge; The right end of the rotating rod 4 is movably connected to the inner wall of the outlet pipe body 2 through a bearing. The left end of the rotating rod 4 penetrates to the outside of the outlet pipe body 2 and is movably connected to the inner cavity of the outlet pipe body 2. The left side of the connecting rod 6 is movably connected to the connecting handle 7 through a bearing; The surface of the fixed block 9 is movably connected to the inner cavity of the positioning block 10; The front end of the movable column 12 penetrates through the connecting seat 11 and is movably connected to the inner cavity of the connecting block 13 through a rotating shaft; The limiting block 17 is movably connected to the inner cavity of the limiting groove 16, and one side of the limiting block 17 penetrates through the limiting groove 16 and is fixedly connected to one side of the movable plate 14.

[0025] The working principle and beneficial effects of the above technical solution are as follows: When in use, when there are sundries in the grille inside the outlet pipe body 2, open the cover plate 3, pull the connecting handle 7 to displace backward and upward. The connecting handle 7 drives the connecting rod 6 to displace in an arc. The connecting rod 6 drives the connecting block 13 to displace backward, and at the same time drives the rotating rod 4 to rotate. The rotating rod 4 drives the rear end of the metal plate 5 to displace upward, driving the sundries in the grille inside the outlet pipe body 2 upward. The metal plate 5 is inclined at an angle, and the sundries slide along the surface of the metal plate 5 and fall outside the outlet pipe body 2 through the good plate. During the process of the connecting block 13 displacing backward, it drives the movable column 12 to displace into the inner cavity of the connecting seat 11. The movable column 12 drives the movable plate 14 to displace, and the movable plate 14 drives the spring 15 to displace. The spring 15 deforms under force. After cleaning the sundries in the grille inside the outlet pipe body 2, release the connecting handle 7. The reset elastic force generated by the spring 15 pushes the movable plate 14 to displace. The movable plate 14 drives the movable column 12 and the connecting block 13 to displace, and then drives the metal plate 5 to reset through the connecting rod 6 and the rotating rod 4, and the cleaning can be completed. During the process of the movable plate 14 displacing, it drives the limiting block 17b to displace in the inner cavity of the limiting groove 16a, limiting the movable plate 14, making the displacement of the movable plate 14 in the inner cavity of the connecting seat 11 more stable, and at the same time increasing the service life of the equipment.

When the actual safe use coefficient of the spring 15 is greater than or equal to the rated safe use coefficient of the spring 15, the automatic cleaning device works normally.

[0027] The working principle and beneficial effects of the above technical solution are as follows: The first calculation module calculates the actual safety factor of the spring 15 based on the radius of the spring 15. The alarm module is used to issue an alarm. The processing module compares and processes the actual safety factor of the spring 15 obtained by the first calculation module with the rated safety factor of the spring 15. When the actual safety factor of the spring 15 is less than the rated safety factor of the spring 15, the control module controls the alarm module to issue an alarm and simultaneously controls the automatic cleaning device to stop working. When the actual safety factor of the spring 15 is greater than or equal to the rated safety factor of the spring 15, the automatic cleaning device works normally.
