Description

Technical Field

[0001] This utility model relates to the field of vertical incinerators, and more specifically, to a slag discharge device for a vertical rotating grate incinerator. Background Technology

[0002] A vertical incinerator is a device used for waste treatment. Designed with a vertical structure, it is commonly used to incinerate solid waste, liquid waste, or sludge. Patent publication number CN211475939U discloses a vertical waste incinerator, relating to the field of incinerator technology. It addresses the problem that existing incinerators struggle to effectively control the combustion intensity within the incinerator during waste incineration, and that post-incineration waste residue discharge can cause blockages. The incinerator body has a support frame at its lower part, with an ash hopper inside the support frame. The vertical centerline of the ash hopper coincides with the vertical centerline of the incinerator body. The incinerator body contains a fuel compartment and an incineration compartment. Both the fuel compartment and the incineration compartment have airtight doors on their front ends. One end of each airtight door has a hinge, which rotatably connects the door to the outer wall of the incinerator body. The other end of each airtight door has a latch, which fixes the door to the outer wall of the incinerator body. A handle is also provided on the airtight door.

[0003] While existing technologies can control the degree of combustion of waste inside incinerators, a large amount of waste residue accumulates on the surface of the filter screen during the incineration process. In addition, some waste, such as plastics and synthetic materials, produces sticky substances during combustion, which adhere to the filter screen and the inner wall of the incinerator. Once accumulated, this affects the waste removal efficiency. Therefore, a slag removal device that can solve the problem of waste accumulation is needed. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a slag discharge device for a vertical rotary grate incinerator.

Furthermore, the vibrated waste slag is rolled, crushed, and shredded again, achieving secondary processing of the slag and making the slag more finely broken, thereby improving the overall waste treatment efficiency of the incinerator.

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0031] Example 1:

[0032] Please see Figure 1-5 A vertical incinerator rotary grate slag discharge device includes a vertical incinerator body 1, a support plate 2 fixedly installed on the outside of the vertical incinerator body 1, a slag guide hopper 3 fixedly connected to the bottom end of the vertical incinerator body 1, a waste slag collection box 4 fixedly installed at the bottom end of the slag guide hopper 3, a limiting circular hole 301 opened inside the slag guide hopper 3, a crushing device 5 rotatably installed inside the slag guide hopper 3, an inclined platform 302 integrally formed inside the slag guide hopper 3, a connecting groove 303 opened inside the inclined platform 302, a connecting groove 303 opened on the side of the connecting groove 303 inside the slag guide hopper 3, and a vibration device 6 movably installed on the surface of the inclined platform 302.

[0033] It should be noted that how the waste is incinerated inside the vertical incinerator body 1 in this utility model and how the degree of incineration is controlled are all existing technologies. Therefore, the specific internal structure will not be described in detail in this solution.

[0034] The crushing device 5 includes a motor 501, with a gear 502 fixedly sleeved on the output shaft of the motor 501. A cam 503 is fixedly installed on the outer end of the gear 502. A belt 504 meshes with the surface of the gear 502. A gear 505 meshes with the inside of the belt 504. A chopping roller 506 is fixedly installed on the inner side of the gear 505. A limiting post 507 is fixedly installed on one end of the chopping roller 506. There are two gears 505. The two gears 505 and the gear 502 are arranged in an equilateral triangle. The limiting post 507 is rotatably installed inside the limiting circular hole 301. The motor 501 is fixedly connected to the outer wall of the slag guide hopper 3.

[0035] Specifically, the limiting circular hole 301 is used to provide support and limit the rotation of the entire shredding roller 506, ensuring that the two shredding rollers 506 can rotate stably. Similarly, the equilateral triangular arrangement of gear 1 502 and gear 2 505 can ensure that the three corners of the belt 504 are in a wrap angle state that will not be misaligned, thus ensuring the stability of the transmission and thereby ensuring the stable rotation of the shredding roller 506.

[0036] The vibration device 6 includes an arc-shaped plate 601. A transmission frame 602 is fixedly installed on the side of the arc-shaped plate 601. A slide rod 603 is fixedly installed at one end of the transmission frame 602. A sleeve rod 604 is integrally formed in the middle of the slide rod 603. A spring 605 is fixedly connected to the surface of the sleeve rod 604. An inclined plate 606 is fixedly installed at the outer end of the sleeve rod 604. The shape of the sleeve rod 604 is adapted to the shape of the sleeve groove 303. One end of the spring 605 is fixedly connected to the inside of the sleeve groove 303, and the other end is fixedly connected to the side of the protruding position of the sleeve rod 604. The shape of the inclined plate 606 is adapted to the shape of the inclined platform 302. There are two arc-shaped plates 601. The positions of the two arc-shaped plates 601 correspond to the positions of the cam 503. A heating hole 607 is opened on the side of the inclined plate 606. A heating copper rod is detachably installed inside the heating hole 607.

[0037] Specifically, the sliding rod 603 and the connecting rod 604, together with the connecting groove 303 and the sliding groove 304, ensure that the entire vibration device 6 has a limiting function when moving. Then, the spring 605 has a back-and-forth vibration function when compressed and released, ensuring that the inclined plate 606 vibrates continuously, improving the source of initial kinetic energy for the arc plate 601 and the cam 503. Finally, the copper rod inside the heating hole 607 can heat the surface of the inclined plate 606, so that some stubborn debris and slag, even if cooled and stuck to the surface, cannot be shaken off. The purpose of cleaning the debris can be achieved by heating in conjunction with vibration.

[0038] The working principle of this utility model is as follows: After the waste is incinerated inside the vertical incinerator body 1, the slag enters the slag guide hopper 3. Then, the motor 501 is started, and the gear 502 and cam 503 rotate simultaneously. The rotation of cam 503 drives two arc-shaped plates 601 to move in opposite directions, and then the spring 605 is stretched. When cam 503 rotates from the farthest left and right ends to the farthest top and bottom ends, the arc-shaped plates 601 lose pressure, the spring 605 returns to its original position, and drives the inclined plate 606 to vibrate. At this time, the waste slag on the surface of the inclined plate 606 vibrates and falls above the shredding roller 506.

[0039] When gear 1 502 rotates, it drives belt 504 to move, which in turn drives gear 2 505 to rotate. Together with limit post 507, the two shredding rollers 506 rotate in place. The falling garbage passes through the shredding rollers 506, is crushed by the shredding rollers 506, and finally falls into the garbage collection box 4 for collection.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
