[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figure 1 As shown;

[0025] An anti-clogging slag removal device for flue gas desulfurization and denitrification comprises a desulfurization tower 1.

[0026] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the anti-clogging slag discharge equipment for industrial flue gas desulfurization and denitrification currently on the market is not easy to crush the waste slag during slag discharge, which can easily cause large waste slag to be stuck in the device, causing blockage in the device, making it difficult to clean it, increasing the labor burden, and being blocked in the device for a long time, causing corrosion to the device, reducing the service life of the device, poor practicality, and not conducive to promotion and use", combined with actual use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a slag discharge component 2 is added on this basis.

[0027] like Figure 1-Figure 5 As shown;

[0028] In combination with the above, in order to prevent large slag from clogging the connecting pipe, a slag discharge assembly 2 connected to the desulfurization tower 1 is also included;

[0029] The slag discharge assembly 2 includes a pair of legs 21 and a slag discharge bin 22 provided on the top of the two legs 21 . A slag crushing mechanism 23 and a vibrating slag discharge mechanism 24 are provided inside the slag discharge bin 22 .

[0030] In this embodiment, the desulfurized solid waste residue is first squeezed and crushed by the slag crushing mechanism 23, and then the slag is discharged by the vibration slag discharge mechanism 24. The two are matched and cyclically operated to ensure that the solid waste residue meets the discharge standard.

[0031] In an optional embodiment, the slag crushing mechanism 23 includes a screw 231 that is transversely penetrated by a bearing and is arranged on the two inner walls of the slag discharge bin 22, and a first reduction motor 232 fixed to the right side wall of the slag discharge bin 22. The rotor of the first reduction motor 232 is fixedly connected to the screw 231, and the thread directions of the left and right ends of the screw 231 are opposite. The left and right ends of the screw 231 are respectively screwed with a left extrusion plate 233 and a right extrusion plate 234.

[0032] In this embodiment: the screw 231 is driven to rotate by the first reduction motor 232. Since the left extrusion plate 233 and the right extrusion plate 234 are respectively screwed onto the threads in different directions at both ends of the screw 231, and the left extrusion plate 233 and the right extrusion plate 234 are limited by the filter 247, the rotation of the screw 231 drives the left extrusion plate 233 and the right extrusion plate 234 to move in opposite directions, thereby crushing the solid waste.

[0033] In an optional embodiment, the vibrating slag discharge mechanism 24 includes a pair of chutes 241 opened on the left and right inner walls of the slag discharge bin 22, a rotating rod 242 arranged on the two inner walls of the slag discharge bin 22 through bearings, and a second reduction motor 243 fixed to the left side wall of the slag discharge bin 22. A slider 244 that slides up and down is provided inside the chute 241, and a sliding rod 245 is longitudinally provided inside the chute 241. The slider 244 is sleeved on the sliding rod 245 and slides up and down on the sliding rod 245. A spring 246 is sleeved on the sliding rod 245 at the top of the slider 244, and a filter screen 247 is provided between the two sliders 244. The rotor of the second reduction motor 243 is fixedly connected to the rotating rod 242, and three eccentric top blocks 248 are provided at both ends and the middle of the rotating rod 242.

[0034] In this embodiment: the second reduction motor 243 drives the rotation of the rotating rod 242, and at the same time the eccentric top block 248 follows the rotation. The circumferential rotation of the eccentric top block 248 pushes the filter screen 247 to perform axial movement in the up and down directions, thereby performing a slag discharge operation on the waste slag on the top of the filter screen 247.

[0035] Working principle of this utility model:

[0036] The solid waste enters the slag discharge assembly 2 through the desulfurization tower, and the screw 231 is driven to rotate by the first reduction motor 232. Since the left extrusion plate 233 and the right extrusion plate 234 are respectively screwed on the threads in different directions at both ends of the screw 231, and the left extrusion plate 233 and the right extrusion plate 234 are limited by the filter 247, the rotation of the screw 231 drives the left extrusion plate 233 and the right extrusion plate 234 to move in opposite directions, thereby crushing the solid waste. The second reduction motor 243 drives the rotation of the rotating rod 242, and at the same time, the eccentric top block 248 rotates accordingly. The circumferential rotation of the eccentric top block 248 pushes the filter 247 to move axially in the up and down directions, thereby discharging the waste on the top of the filter 247. The desulfurized solid waste is first squeezed and crushed by the slag crushing mechanism 23, and then the slag is discharged by the vibrating slag discharge mechanism 24. The two are matched and cyclically operated to ensure that the solid waste meets the discharge standard and prevent larger slag from clogging the connecting pipe.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
