Description

Technical Field

[0001] This utility model relates to the field of slag treatment technology for municipal solid waste incineration power plants, and in particular to a crusher for slag treatment in municipal solid waste incineration power plants. Background Technology

[0002] In municipal solid waste incineration power plants, the treatment of slag, a byproduct of incineration, is a crucial step. Slag typically requires crushing to facilitate subsequent resource recycling or safe landfill disposal.

[0003] However, existing slag crushers have some problems during use.

[0004] Larger slags may get stuck inside the crusher, preventing them from sliding down smoothly and causing blockages that reduce the crushing speed.

[0005] In addition, the crusher needs to be shut down when changing the material receiving hopper, which not only affects production efficiency but may also cause slag to accumulate inside the crusher, increasing the difficulty of cleaning.

[0006] Therefore, developing a slag crusher that can effectively solve the above problems is of great practical significance. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies, such as the potential for large slag particles to become stuck inside the crusher, preventing them from sliding smoothly and causing blockages that reduce the crushing speed. Furthermore, the crusher needs to be stopped when changing the receiving hopper, which not only affects production efficiency but may also lead to slag accumulation inside the crusher, increasing cleaning difficulty. Therefore, this invention proposes a crusher for handling slag from municipal solid waste incineration power plants.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A crusher for treating slag from a municipal solid waste incineration power plant includes a crusher shell. A vertical hole is provided on one side of the top of the crusher shell, and the bottom of the vertical hole extends to the bottom of the crusher shell. A receiving cavity is provided on one inner wall of the vertical hole, and the receiving cavity is connected to the vertical hole. Slotted holes are provided on both sides of the crusher shell, and a set of crushing components for crushing slag is provided between the two slotted holes.

[0010] A pressure plate slides through one side of the crusher shell, and a triangular plate is fixedly connected to the inner wall of one side of the vertical hole. A gap is left between the triangular plate and the pressure plate, and a gap is left between the tip of the triangular plate and the inner wall of one side of the vertical hole for the entry of slag. A discharge assembly for discharging slag is provided at the bottom of the vertical hole.

[0011] A U-shaped plate is fixedly connected to the top of the crusher shell, and an adjustment component for adjusting the position of the pressure plate is provided on one side of the U-shaped plate.

[0012] In one possible design, the crushing assembly includes a rectangular slider slidably connected inside the strip-shaped hole. The two rectangular sliders are rotated through the same shaft. A crushing roller is fixedly sleeved on the outer wall of the shaft. Multiple rotating pressure strips are fixedly sleeved on the outer wall of the crushing roller. Multiple fixed pressure strips are fixedly connected to the inner wall of one side of the vertical hole. The fixed pressure strips cooperate with the rotating pressure strips and are used to crush the slag.

[0013] In one possible design, dustproof plates are slidably connected to both sides of the crusher housing. The dustproof plates are used to block the strip-shaped holes. A drive motor is fixedly connected to one side of one of the dustproof plates, and the output shaft of the drive motor is fixedly connected to one end of the rotating shaft.

[0014] In one possible design, the discharge assembly includes a sliding trapezoidal block slidably connected to the inner wall of one side of the vertical hole via a slider and a slide rail. Side plates are fixedly connected to both sides of the top of the sliding trapezoidal block, and the top of the two side plates is fixedly connected to the same baffle, which is used to block one side of the receiving cavity.

[0015] In one possible design, the adjustment assembly includes an electric push rod fixedly connected to one side of the U-shaped plate, the piston rod of the electric push rod being fixedly connected to a vertical plate, one side of the vertical plate being fixedly connected to one side of the pressure plate, and a pushing trapezoidal block being fixedly connected to one side of the vertical plate. The pushing trapezoidal block cooperates with a sliding trapezoidal block and is used to push the sliding trapezoidal block upward.

[0016] In one possible design, connecting rods are fixedly connected to both sides of the vertical plate, and a horizontal plate is fixedly connected to one side of each connecting rod. The horizontal plate is fixedly connected to one end of the dustproof plate and is used to push the dustproof plate to move laterally.

[0017] In one possible design, a door panel is hinged to one side of the receiving cavity, a handle is fixedly connected to one side of the door panel, and an inclined groove is formed on the top inner wall of the crusher housing.

[0018] In this application, during use, the slag slides down the surface of the inclined chute into the interior of the crusher shell. The slag slides down through the gap between the pressure plate and the inclined chute. The triangular plate feeds the slag into the inner wall of one side of the vertical hole, which can facilitate fixing the pressure bar and rotating the pressure bar to crush the slag.

[0019] Start the drive motor, the output shaft of the drive motor drives the rotating shaft to rotate, the rotating shaft drives the crushing roller to rotate, the crushing roller drives multiple rotating pressure bars to rotate, the multiple rotating pressure bars can fit with multiple fixed pressure bars, thereby crushing the slag, the crushed slag is discharged along the surface of the sliding trapezoidal block and from the gap between the baffle and the sliding trapezoidal block;

[0020] After a period of use, larger slags will gradually become stuck on the surface of the triangular plate and will not be able to slide off, which will gradually cause a decrease in the slag crushing speed. Or when it is necessary to replace the material box used for receiving materials below, the electric push rod can be activated. The electric push rod drives the vertical plate to move laterally, and the vertical plate drives the pressure plate to move laterally. The gap between the inclined surface of the pressure plate and the triangular plate gradually decreases, squeezing the slag. At the same time, one end of the pressure plate abuts against the inner wall of one side of the vertical hole, continuing to squeeze the slag moving upward from the surface of the triangular plate, breaking it into small pieces for easy subsequent crushing.

[0021] At the same time, the vertical plate drives the connecting rod to move laterally, the connecting rod drives the horizontal plate to move laterally, the horizontal plate drives the dustproof plates on both sides to move laterally, the dustproof plates drive the internal crushing roller to move laterally, the crushing roller temporarily disengages from the fixed pressure bar, so that the slag stuck inside the fixed pressure bar can fall off, which is convenient for the subsequent crushing process. Meanwhile, the dustproof plate always blocks the strip holes on both sides of the crusher shell to prevent slag from leaking out.

[0022] Furthermore, the vertical plate can drive the trapezoidal block to move laterally, and the inclined surface of the trapezoidal block can drive the sliding trapezoidal block to move upward. The sliding trapezoidal block can drive the side plate to move upward, and the side plate can drive the baffle to move upward. At this time, the baffle no longer blocks one side of the receiving cavity. The bottom of the inclined surface of the sliding trapezoidal block is flush with the bottom inner wall of the receiving cavity. Some of the slag that is squeezed down by the pressure plate will enter the inside of the receiving cavity along the sliding trapezoidal block for temporary storage, preventing the slag that has not been completely crushed from falling to the outside. At this time, the sliding trapezoidal block blocks the bottom of the vertical hole, which makes it convenient to replace the collection box.

[0023] Beneficial effects: Through the gap between the pressure plate and the inclined groove, the cooperation between the triangular plate and the vertical hole, and the mutual squeezing action of the fixed pressure bar and the rotating pressure bar, the slag can be easily crushed, thus improving the crushing efficiency of the slag.

[0024] When larger slag pieces get stuck on the surface of the triangular plate and cannot slide off, the electric push rod can be activated to move the pressure plate laterally, squeezing the slag and breaking it into smaller pieces. This effectively avoids slag blockage and ensures the stability of the slag crushing speed.

[0025] The dustproof plate always blocks the strip holes on both sides of the crusher shell, preventing slag leakage, reducing environmental pollution, and also protecting the equipment inside the crusher from external interference.

[0026] When replacing the lower material receiving bin, an electric push rod temporarily disengages the crushing roller from the fixed pressure bar, allowing the slag stuck inside the pressure bar to fall out, facilitating the subsequent crushing process. Simultaneously, pushing the trapezoidal block causes the sliding trapezoidal block to move upwards, preventing the baffle from blocking one side of the receiving cavity. Some of the slag squeezed down by the pressure plate enters the receiving cavity along the sliding trapezoidal block for temporary storage, preventing incompletely crushed slag from falling outside. At this point, the sliding trapezoidal block blocks the bottom of the vertical hole, facilitating the replacement of the collection bin and improving production efficiency.

The fixed pressure strips 18 are used in conjunction with the rotating pressure strips 24 to crush the slag. Dustproof plates 2 are slidably connected to both sides of the crusher shell 1. The dustproof plates 2 are used to block the strip-shaped holes. A drive motor 3 is fixedly connected to one side of one of the dustproof plates 2.

[0036] A pressure plate 6 slides through one side of the crusher housing 1. A triangular plate 16 is fixedly connected to the inner wall of one side of the vertical hole 15. A gap is left between the triangular plate 16 and the pressure plate 6, and a gap is left between the tip of the triangular plate 16 and the inner wall of one side of the vertical hole 15 for the slag to enter. The slag slides down the surface of the inclined chute 9 into the interior of the crusher housing 1. The slag slides down through the gap between the pressure plate 6 and the inclined chute 9. The triangular plate 16 feeds the slag into the inner wall of one side of the vertical hole 15, which facilitates the fixing of the pressure bar 18 and the rotation of the pressure bar 24 to crush the slag. A discharge assembly for discharging slag is provided at the bottom of the vertical hole 15. The discharge assembly includes a sliding trapezoidal block 21 slidably connected to the inner wall of one side of the vertical hole 15 via a slider and a slide rail. Side plates 20 are fixedly connected to both sides of the top of the sliding trapezoidal block 21. A baffle 19 is fixedly connected to the top of both side plates 20, and the baffle 19 is used to seal one side of the receiving cavity 17. The drive motor 3 is started, and the output shaft of the drive motor 3 drives the rotating shaft 12 to rotate. The rotating shaft 12 drives the crushing roller 23 to rotate, and the crushing roller 23 drives multiple rotating pressure bars 24 to rotate. The multiple rotating pressure bars 24 can fit against multiple fixed pressure bars 18, thereby crushing the slag. The slag flows along the surface of the sliding trapezoidal block 21 and is discharged through the gap between the baffle 19 and the sliding trapezoidal block 21. Simultaneously, the vertical plate 7 drives the connecting rod 5 to move laterally, which in turn drives the horizontal plate 11 to move laterally. The horizontal plate 11 then drives the dustproof plates 2 on both sides to move laterally, which in turn drives the internal crushing roller 23 to move laterally.

At this time, the baffle 19 no longer blocks one side of the receiving cavity 17. The bottom of the inclined surface of the sliding trapezoidal block 21 is flush with the bottom inner wall of the receiving cavity 17. Some of the slag that is squeezed down by the pressure plate 6 will enter the interior of the receiving cavity 17 along the sliding trapezoidal block 21 for temporary storage, preventing the slag that has not been completely crushed from falling to the outside. At this time, the sliding trapezoidal block 21 blocks the bottom of the vertical hole 15, which makes it convenient to replace the collection box.

After a period of use, larger slag particles become stuck in the triangular... If the surface of plate 16 cannot slide off, it will gradually become clogged, resulting in a decrease in the slag crushing speed. Alternatively, when it is necessary to replace the material box used for receiving materials below, the electric push rod 10 can be activated. The electric push rod 10 drives the vertical plate 7 to move laterally, and the vertical plate 7 drives the pressure plate 6 to move laterally. The gap between the inclined surface of the pressure plate 6 and the triangular plate 16 gradually decreases, squeezing the slag.
