Description

Technical Field

[0001] The utility model relates to the technical field of waste incineration treatment, and particularly relates to a slag remover for an incinerator. Background Art

[0002] Waste incineration treatment is a widely used waste treatment method at present, and its common equipment is a waste incineration grate furnace. After the waste is completely burned on the grate, it forms slag and is discharged to the slag remover. The slag remover collects the slag until a certain amount and then discharges the slag.

[0003] In the existing slag remover, the slag in the slag remover is pushed out to the outside of the slag remover through a push head. However, the existing push head rubs against the inner wall of the slag remover for a long time, which will cause wear of the push head. If the push head does not rub against the inner wall of the slag remover, there will be a certain gap between the push head and the inner wall of the slag remover, resulting in incomplete slag removal and a small amount of slag remaining in the slag remover.

[0034] A slag collection chamber 4 is formed inside the housing 1. An inlet for slag 5 is formed at the top of the slag collection chamber 4, and an outlet for slag 6 is formed at the front end of the slag collection chamber 4;

[0035] The push head 2 is arranged inside the slag collection chamber 4;

[0036] The drive assembly 17 is connected to the push head 2, and the drive assembly 17 is used to drive the push head 2 to reciprocate inside the slag collection chamber 4 to push the slag inside the slag collection chamber 4 to be discharged from the outlet for slag 6;

[0037] The water replenishing assembly is located at the rear end of the housing 1, and the water replenishing assembly is used to inject water into the slag collection chamber 4;

[0038] The scraper 3 is detachably connected to the push head 2.

[0039] In this embodiment, the slag in the incinerator enters the slag collection chamber 4 through the slag inlet 5. There is water with a certain depth in the slag collection chamber 4. The liquid water is used to extinguish the slag and cool down the slag. The liquid water in the slag collection chamber 4 has a certain loss. The water replenishing component is used to replenish water into the slag collection chamber 4 so that the water level in the slag collection chamber 4 is always maintained within a preset range; the driving component 17 is used to drive the push head 2 and the scraper 3 to reciprocate to push the slag in the slag collection chamber 4 out from the slag outlet 6. It should be particularly noted here that the driving component 17 in the slag remover is a prior art, so the driving component 17 will not be described in detail here. And, in this embodiment, the driving component 17 adopts the driving mode of a hydraulic cylinder. In other embodiments, other driving modes can also be adopted; by detachably connecting a scraper 3 to the push head 2, it can prevent the push head 2 from directly contacting the inner wall of the bottom of the slag collection chamber 4, thereby causing wear of the push head 2. And by making the scraper 3 close to the inner wall of the bottom of the slag collection chamber 4, it can not only ensure that the slag at the bottom of the slag collection chamber 4 can be smoothly pushed out, but also, when the wear of the scraper 3 reaches a certain degree, a scraper 3 can be directly replaced. Replacing the scraper 3 is not only lower in cost but also lower in replacement difficulty compared with replacing the push head 2.

[0040] Further, the bottom of the slag collection chamber 4 is arc-shaped.

[0041] Further, a trapezoidal guide rail 7 is provided on the scraper 3, and a dovetail groove 8 matching with the trapezoidal guide rail 7 is provided on the push head 2. The scraper 3 is slidably connected to the push head 2 through the cooperation of the trapezoidal guide rail 7 and the dovetail groove 8. A fixing component is also provided between the scraper 3 and the push head 2.

[0042] In this embodiment, the scraper 3 is slidably connected to the push head 2 through the cooperation of the trapezoidal guide rail 7 and the dovetail groove 8. Therefore, when the wear of the scraper 3 reaches a certain degree, by opening the fixing component, the scraper 3 can slide on the push head 2, and then the position of the scraper 3 is adjusted so that the scraper 3 reaches the optimal working position, and finally the scraper 3 is fixed on the push head 2 through the fixing component.

[0043] Further, the fixing component includes a threaded rod 9, a fixing block 10, a first locking nut 11 and a second locking nut 12;

[0044] The threaded rod 9 is integrally formed with the scraper 3, and the threaded rod 9 is parallel to the trapezoidal guide rail 7;

[0045] The fixed block 10 is fixedly connected to the push head 2. A circular hole for the threaded rod 9 to pass through is formed in the fixed block 10. The first locking nut 11 and the second locking nut 12 are respectively threadedly connected to the threaded rod 9, and one end face of the first locking nut 11 is in contact with one end face of the fixed block 10, and the other end face of the second locking nut 12 is in contact with the other end face of the fixed block 10.

[0046] In this embodiment, the working principle of the fixing assembly is that when the position of the scraping plate 3 needs to be adjusted, the first locking nut 11 and the second locking nut 12 are screwed, so that the first locking nut 11 and the second locking nut 12 move away from the fixed block 10 respectively. At this time, the position of the scraping plate 3 can be adjusted; when the position of the scraping plate 3 needs to be fixed, the first locking nut 11 and the second locking nut 12 are screwed, so that the first locking nut 11 and the second locking nut 12 are tightly in contact with the end faces of the fixed block 10 respectively.

[0047] Further, the water replenishing assembly includes a water pump 13, a first water pipe 14, a second water pipe 15 and a water level sensor 16;

[0048] The water pump 13 is fixedly connected to the outside of the housing 1;

[0049] One end of the first water pipe 14 is connected to the water pump 13, and the other end of the first water pipe 14 is externally connected to a water source;

[0050] One end of the second water pipe 15 is connected to the water pump 13, and the other end of the second water pipe 15 extends into the slag collection chamber 4;

[0051] The water level sensor 16 is arranged in the slag collection chamber 4, and the water level sensor 16 is used to monitor the water level in the slag collection chamber 4.

[0052] In this embodiment, when the water level is lower than the lowest preset value, the water pump 13 starts to operate. The water at the water source sequentially passes through the first water pipe 14, the water pump 13 and the second water pipe 15, and finally enters the slag collection chamber 4. It should be noted here that each time the water pump 13 starts, the running time of the water pump 13 is a fixed value. Therefore, each time the water pump 13 works, the amount of water replenished into the slag collection chamber 4 is a fixed value.

[0053] The above is only the preferred embodiment of the present invention, and it does not limit the patent scope of the present invention. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
