[0027] See also Figure 1 - Figure 5 The utility model provides a vertical rotary cracking incinerator with a grate, including a furnace body 1, a discharge pipe 2 is installed at the center of the outer wall of the furnace body 1, the discharge pipe 2 and the furnace body 1 are mutually connected, a rotary grate 3 is installed inside the furnace body 1, a plurality of contact rollers 31 are installed on the outer periphery of the rotary grate 3 through a bracket, and the plurality of contact rollers 31 are installed equidistantly along the outer periphery of the rotary grate 3, and the outer walls of the contact rollers 31 are rollingly installed in the inner wall grooves of the discharge pipe 2, a track plate 32 is fixedly connected to the lower part of the bracket of the contact roller 31, and the track plate 32 is slidingly fitted in the lower inner wall of the discharge pipe 2, and a collection box 4 is installed on one side of the outer wall of the furnace body 1 through a bracket, and the collection box 4 A feeding pipe 41 is installed above the furnace body 1, one end of which is connected to the inside of the discharge pipe 2, and a blocking assembly 5 is installed inside the furnace body 1. The contact roller 31 on the rotating grate 3 and the track in the discharge pipe 2 fit each other inside the furnace body 1, so that an opening for waste to enter the discharge pipe 2 can be reserved while the furnace body 1 and the rotating grate 3 are rotatably installed, and the opening is blocked by the blocking assembly 5. When waste flows into the discharge pipe 2, the track plate 32 that rotates with the rotating grate 3 can swing the waste to rotate with the discharge pipe 2, and when passing through the area connected to the feeding pipe 41, it enters the collecting box 4 from the feeding pipe 41, so that the device can collect waste;

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the material blocking assembly 5 includes a first material blocking ring 51 and a second material blocking ring 52. The upper portion of the outer wall of the first material blocking ring 51 is fixedly connected to the inner wall of the furnace body 1 near the interface of the discharge pipe 2. The second material blocking ring 52 is rotatably sleeved on the inner wall of the first material blocking ring 51. The first material blocking ring 51 and the inner wall of the furnace body 1 are fixedly connected to each other to achieve the installation of the material blocking assembly 5 on the furnace body 1. The relative rotation between the first material blocking ring 51 and the second material blocking ring 52 enables the device to adjust the blocking state of the material blocking assembly 5 on the feed port between the furnace body 1 and the discharge pipe 2 according to actual conditions.

[0029] like Figure 3 and Figure 4As shown, the outer circumference of the first stopper ring 51 is provided with a plurality of first discharge openings 511, and the plurality of first discharge openings 511 are equidistantly installed along the outer circumferential direction of the first stopper ring 51, and the inner wall of the second stopper ring 52 is provided with a plurality of second discharge openings 521, and the plurality of second discharge openings 521 are respectively located at the vertical projections of the plurality of first discharge openings 511. When a certain amount of large-particle waste is accumulated on the rotating grate 3, it is necessary to control it to enter the discharge pipe 2 from the interface between the furnace body 1 and the discharge pipe 2. At this time, the second stopper ring 52 is rotated to make the second discharge openings 521 and the first discharge openings 511 relative to each other, and at this time, the waste can enter the discharge pipe 2 through the second discharge openings 521 and the first discharge openings 511.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, the outer wall of the furnace body 1 is provided with a straight slot opening 11, and a lever 522 is vertically fixedly connected to the upper outer wall of the second material blocking ring 52.

One end of the electric telescopic rod 53 is hingedly connected to a side wall bracket 12. The side wall bracket 12 is fixedly connected to the outside of the furnace body 1. When the discharge port between the furnace body 1 and the discharge pipe 2 is blocked, the electric telescopic rod 53 is retracted and the lever 522 is retracted. The second material stopper ring 52 rotates as a whole, and rotates until the first discharge opening 511 and the second discharge opening 521 are closed to each other, the material discharge channel between the furnace body 1 and the discharge pipe 2 is closed, and when material discharge is required, the electric telescopic rod 53 is extended, and the second material stopper ring 52 is reset. At this time, the second discharge opening 521 and the first discharge opening 511 are aligned, wherein the side wall bracket 12 and the electric telescopic rod 53 are hinged so that the process of extending and retracting the electric telescopic rod 53 will not cause movement obstruction;

The plurality of limiting rollers 55 are installed equidistantly along the outer circumference of the second stopper ring 52. The limiting rollers 55 are in contact with the top surface of the first stopper ring 51. The second stopper ring 52 rolls and rubs against the top surface of the first stopper ring 51 through the limiting rollers 55, which increases the vertical installation stability of the first stopper ring 51 and the second stopper ring 52 without having a significant impact on the relative rotation between the first stopper ring 51 and the second stopper ring 52.

[0033] like Figure 3 and Figure 4 As shown, an inclined wall ring 56 is installed above the second material stopper ring 52, and the outer wall of the inclined wall ring 56 is slidably fitted with the inner wall of the furnace body 1.

When the waste flows into the discharge pipe 2, the track plate 32 rotating with the rotating grate 3 can swing the waste to rotate with the discharge pipe 2, and when passing through the area connected to the feed pipe 41, it enters the collecting box 4 from the feed pipe 41, so that the device can collect the waste. When a certain amount of large particles of waste are accumulated on the rotating grate 3, it is necessary to control it to enter the discharge pipe 2 from the interface between the furnace body 1 and the discharge pipe 2. At this time, the second blocking ring 52 is rotated to align the second discharge opening 521 with the first discharge opening 511. At this time, the waste can enter the discharge pipe 2 through the second discharge opening 521 and the first discharge opening 511, and the discharge port between the furnace body 1 and the discharge pipe 2 is When sealing, the electric telescopic rod 53 is retracted, the lever 522 and the second stopper ring 52 rotate as a whole, and rotate until the first discharge opening 511 and the second discharge opening 521 are closed to each other, the unloading channel between the furnace body 1 and the unloading pipe 2 is closed. When unloading is required, the electric telescopic rod 53 is relaxed and the second stopper ring 52 is reset. At this time, the second discharge opening 521 and the first discharge opening 511 are aligned, and the blocking arc plate 54 can rotate with the rotation of the second stopper ring 52 and ensure the blocking state of the straight groove opening 11. The second stopper ring 52 rolls and rubs with the top surface of the first stopper ring 51 through the limiting roller 55, which will not have a significant impact on the relative rotation between the first stopper ring 51 and the second stopper ring 52. The oblique wall ring 56 on the second stopper ring 52 is rotated and fitted with the inner wall of the furnace body 1 to prevent waste from entering the gap between the first stopper ring 51 and the second stopper ring 52.
