[0024] See also Figures 1 to 3The boiler slag removal device provided by the utility model is now described. The boiler slag removal device includes a box body 10, a crushing roller 30, a crushing block 40, a guide plate 50 and a striking assembly 60. The box body 10 is provided with a feed hopper 11 on the top and a discharge port 12 on the side. The outer wall of the box body 10 is provided with a shell 20 located below the discharge port 12; the crushing roller 30 is rotatably connected to the box body 10, and the main shaft extends in the horizontal direction; the crushing block 40 is arranged in the box body 10 and is located on one side of the crushing roller 30. There is a feed hopper 11 between the crushing roller 30 and the crushing block 40. The crushing gap 41 is below the bucket 11; the guide plate 50 is arranged in the box body 10 and is located below the crushing gap 41. The guide plate 50 extends obliquely downward through the discharge port 12 and extends to the outside of the box body 10 for guiding the coal slag; the striking component 60 is arranged in the shell body 20 and upwardly penetrates the top wall of the shell body 20. The striking component 60 is slidably connected to the shell body 20 in the up and down directions. The striking component 60 can move upward to strike the bottom of the guide plate 50 to shake off the coal slag on the guide plate 50.
[0025] Furthermore, the main shaft of the crushing roller 30 extends to the outside of the box body 10 , and the outer end of the main shaft of the crushing roller 30 is connected to the motor 31 .
[0026] Furthermore, a first crushing tooth is provided on the outer peripheral wall of the crushing roller 30 , and a second crushing tooth is provided on the side wall of the crushing block 40 close to the crushing roller 30 .
[0027] The embodiment of the present application provides a boiler slag removal device. During its actual use, the coal slag in the boiler enters the box body 10 from the feed hopper 11 and reaches the crushing gap 41. The crushing roller 30 rotates and cooperates with the crushing block 40 to crush the coal slag. The crushed coal slag falls onto the guide plate 50. At the same time, the striking component 60 strikes the guide plate 50 to vibrate the guide plate 50, thereby promoting the coal slag on the guide plate 50 to roll from the discharge port 12 to the outside of the box body 10. This not only avoids the large volume of coal slag from clogging the discharge port 12, but also avoids the accumulation of coal slag on the guide plate 50, thereby saving manpower and improving the slag removal efficiency.
[0028] Compared with the prior art, the boiler slag removal device provided in this embodiment crushes the coal slag in the crushing gap 41 through the crushing roller 30 and the crushing block 40. The crushed coal slag falls onto the guide plate 50, and at the same time, the striking component 60 strikes the guide plate 50 to vibrate the guide plate 50, thereby promoting the coal slag on the guide plate 50 to roll from the discharge port 12 to the outside of the box body 10, which not only avoids the large volume of coal slag from clogging the discharge port 12, but also avoids the accumulation of coal slag on the guide plate 50, thereby saving manpower and improving the slag removal efficiency.
[0029] In a possible implementation, the striking assembly 60 is configured as follows: Figure 1 and Figure 2The structure shown, see Figure 1 and Figure 2 The striking assembly 60 includes a push rod 61, an elastic member 62 and an electromagnet 63. The push rod 61 is arranged in the shell 20 and penetrates the top wall of the shell 20 upward. The push rod 61 is slidably connected to the shell 20 along the up and down directions; the elastic member 62 is sleeved on the outer periphery of the push rod 61, the upper end of the elastic member 62 is connected to the inner top wall of the shell 20, and the lower end is connected to the push rod 61; the electromagnet 63 is arranged on the inner bottom wall of the shell 20, and is used to attract the push rod 61 to move downward.
[0030] Specifically, when the electromagnet is powered on, the electromagnet 63 attracts the push rod 61 to move downward, and the push rod 61 compresses the elastic member 62. When the electromagnet 63 is powered off, the elastic member 62 pushes the push rod 61 upward, so that the push rod 61 hits the bottom surface of the guide plate 50 located outside the box body 10, thereby vibrating the guide plate 50 to shake off the coal slag on the guide plate 50 and pass through the discharge port 12. When in use, the electromagnet 63 can be repeatedly powered on and off to repeatedly hit the guide plate 50, thereby improving the slag removal efficiency.
[0031] In some embodiments, see Figure 1 and Figure 2 The lower end of the push rod 61 is provided with a boss 64 protruding toward the outer circumference, and the lower end of the elastic member 62 is connected to the upper end surface of the boss 64.
[0032] Specifically, the arrangement of the boss 64 facilitates the installation of the elastic member 62 , and the boss 64 cooperates with the top wall inside the housing 20 to limit the elastic member 62 to prevent the elastic member 62 from being separated from the ejector pin 61 .
[0033] In a possible implementation, the guide plate 50 is as follows: Figure 1 The structure shown, see Figure 1 The upper edge of the guide plate 50 is hinged to the inner wall of the box body 10, and the guide plate 50 can swing vertically.
[0034] Specifically, when the striking assembly 60 strikes the guide plate 50 , the guide plate 50 vibrates, and can also cause the guide plate 50 to swing up and then fall back to the initial position to collide with the inner bottom wall of the discharge port 12 , vibrating again, further avoiding the accumulation of coal slag on the guide plate 50 .
[0035] In a possible implementation, the box 10 is configured as follows: Figure 1 The structure shown, see Figure 1 A mounting block 13 is provided on the inner wall of the box body 10 and is located on one side of the crushing roller 30. A chute 14 extending horizontally away from the crushing roller 30 is provided on the side of the mounting block 13 close to the crushing roller 30. The crushing block 40 is slidably connected in the chute 14. An adjusting member 70 for adjusting the horizontal position of the crushing block 40 is provided on the box body 10.
[0036] Specifically, when the size of the crushing gap 41 needs to be adjusted, the adjusting member 70 can be adjusted to allow the crushing block 40 to slide horizontally in the chute 14 to approach or move away from the crushing roller 30, thereby preventing the crushed coal slag from being too large in particle size and clogging the discharge port 12.
[0037] In some embodiments, see Figure 1 The adjusting member 70 is a screw rotatably connected to the side wall of the crushing block 40 away from the crushing roller 30 . The screw penetrates the side wall of the box body 10 along the radial direction of the crushing roller 30 , extends to the outside of the box body 10 , and is threadedly connected to the box body 10 .
[0038] Specifically, a worker rotates the screw rod from the outside of the box body 10 , thereby driving the crushing block 40 to slide horizontally in the chute 14 , thereby facilitating the adjustment of the position of the crushing block 40 .
[0039] In some embodiments, see Figure 1 and Figure 3 The outer end of the screw is connected to a force application disk 71.
[0040] Specifically, the provision of the force applying disk 71 allows the staff to rotate the force applying disk 71 to adjust the screw rod, thereby facilitating the staff to adjust the screw rod.
[0041] In a possible implementation, the guide plate 50 is as follows: Figure 1 The structure shown, see Figure 1 An ash passing hole 51 is formed through the material guide plate 50 , and an ash absorbing member 80 facing the ash passing hole 51 is formed on the inner bottom wall of the box body 10 .
[0042] Specifically, when the crushing roller 30 and the crushing block 40 crush the coal slag, and the striking assembly 60 strikes the guide plate 50, the coal slag will generate a large amount of dust. The dust suction member 80 absorbs the dust from below, allowing the dust to pass through the ash hole 51 into the bottom of the box body 10, thereby preventing the dust from passing through the discharge port 12 to reach the outside and affect the external environment.
[0043] In some embodiments, see Figure 1 The dust suction member 80 includes a rotating driving member 81 and a fan blade 83. The rotating driving member 81 is arranged on the inner bottom wall of the box body 10 and has a driving end extending upward, and the driving end is connected to a rotating shaft 82 extending upward; the fan blade 83 is connected to the upper end of the rotating shaft 82, and is used for sucking dust above the guide plate 50 under the drive of the rotating shaft 82.
[0044] Specifically, driven by the rotating drive member 81, the fan blades 83 are driven to rotate through the rotating shaft 82, so that negative pressure is generated at the bottom of the box body 10, thereby sucking the dust above the guide plate 50 into the bottom of the box body 10, preventing the dust from reaching the outside through the discharge port 12.
[0045] In a possible implementation, the box 10 is configured as follows: Figure 1 The structure shown, see Figure 1 A dust cover 90 is provided on the inner bottom wall of the box body 10 and is covered on the outer periphery of the rotating driving member 81 . The rotating shaft 82 is upwardly penetrated through the top wall of the dust cover 90 .
[0046] Specifically, the rotating shaft 82 is rotatably connected to the dust cover 90 . The provision of the dust cover 90 can prevent dust from entering the interior of the rotating driving member 81 and affecting its normal operation, thereby increasing the service life of the rotating driving member 81 .
[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
