[0034] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment, obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the protection scope of the utility model.

[0035] The utility model will be further described in detail below in combination with the drawings:

[0036] A residue bin drainage drainage device 2 of a residue dredger, as shown in Figures 1-3 , including deflector 3 and drainage groove 4, the inner end of deflector 3 is installed on residue discharge port 11 of residue bin 1, and the outer end of deflector 3 is matched with drainage groove 4.

[0037] Residue water enters deflector 3 from residue discharge port 11 of residue bin 1, and under the action of deflector 3 and drainage groove 4, residue water is discharged to a designated place, such as residue water ditch, to avoid residue water overflow and pollute the environment.

[0038] As Figure 3 , the left and right sides of deflector 3 are respectively provided with baffle 31. Handle 32 is arranged on the upper side of deflector 3, and deflector 3 is detachably installed on residue discharge port 11.

[0039] Specifically, deflector 3 is obliquely arranged, and the inclination is 20-30 °, the length of deflector 3 is 900-1500mm, and the width is 300-450mm, the height of handle 32 is 100-200mm, the distance between handle and baffle is 150-300mm, and the depth of inner end of deflector 3 embedded in residue discharge port 11 is 100-300mm.

[0040] More specifically, the depth of the guide plate 3 embedded in the slag discharge port 11 is 250 mm, the inclination is 26°, the length is 1200 mm, the width is 395 mm, and a handle is arranged in the middle, which is 223 mm away from both ends of the guide plate, and the height of the handle is 140 mm. When the slag car driver discharges slag, the guide plate is pulled out to ensure that the slag in the slag bin falls smoothly into the slag car conveying belt; when the slag bin is not discharging slag, the water in the slag bin flows into the drainage groove through the guide plate, which ensures that most of the water in the first stage slag bin is introduced into the slag water drainage groove, avoiding the direct discharge of a large amount of slag bin water to the ground to cause environmental pollution. The drainage groove 4 is 1490 mm long, 290 mm wide, and 300 mm deep. The right side of the drainage groove 4 is connected to the slag water drainage pipe through a hole in the bottom, and the diameter of the drainage pipe is 76 mm. The drainage groove 4 not only can collect the water in the slag bin, but also can discharge the water in the slag bin to the slag water ditch 6 through the bottom drainage pipe of the drainage groove 4, and finally flow into the slag water collection tank, so that most of the water in the slag bin is discharged to the designated place, preventing the water from flowing out and polluting the ground.

[0041] The output end of the drainage groove 4 is connected to the slag water ditch 6 through a drainage pipe to discharge the slag water to the designated slag water ditch; and the slag discharge port 11 is provided with a pneumatic plug door 12, which can adjust the opening degree of the slag discharge port.

[0042] In the first stage, when the amount of slag and water is small, the slag water can be discharged through the cooperation of the drainage groove and the guide plate.

[0043] In the second stage, when the amount of slag and water increases, most of the slag water enters the drainage assembly 5. As shown in Figure 1 and Figure 2 , the drainage assembly 5 is installed on the lower side of the drainage groove 4; the drainage assembly 5 includes a guide plate 51 and a guide ditch 53 arranged on the guide plate 51, and the guide plate 51 is inclined to the guide ditch 53. The guide plate 51 guides the slag water to the guide ditch 53, and the slag water is discharged to the designated point, i.e. the slag water ditch, through the guide ditch 53.

[0044] The outer side of the guide plate 51 is provided with a cofferdam 52; the side of the guide plate 51 close to the guide ditch 53 is provided with a plurality of guide holes 55. The guide plate 51 is arranged on the ground or arranged on the ground, and the height difference of the guide plate 51 is 2-5 cm; the guide ditch is arranged on the front side and the left side of the guide plate 51; and the cofferdam is arranged on the left side and the back side of the guide plate 51.

[0045] The width of the diversion ditch 53 is 150-200mm, and the depth is 200-300mm, a steel tank is arranged on the diversion ditch 53, a diversion hole 55 is arranged on one side of the steel tank every 600mm, the size of the diversion hole is 75*60*80mm, the diversion ditch 53 is connected with the slag water ditch 6, and the height difference between the diversion ditch 53 and the slag water ditch 6 is 2-5cm. The slag water is prevented from frequently causing the diversion ditch to be blocked, and the effect of smooth ground drainage is promoted. The diversion ditch is connected to the slag water ditch in the area of the slag conveyer, and the height difference is 3cm, so that the slag water in the second stage slag bin is prevented from flowing out, and the slag water is ensured to flow into the slag water ditch smoothly.

[0046] More specifically, the ground surface is slightly inclined in the direction of the slag bin, the height difference between the left and right sides is 2cm, the width of the diversion ditch is 160mm, and the depth is 250mm, so that the slag water in the slag bin is introduced into the left diversion ditch 53 through the gravity of the water flow, and the slag water can be introduced into the ditch.

[0047] According to the property of the water flow and the gravity effect, the slag water in the slag bin is introduced into the slag water ditch in stages, the slag water in the slag bin is introduced into the slag water ditch in stages, the slag water in the slag bin is introduced into the slag water ditch in stages, and the slag water in the slag bin is introduced into the slag water ditch in stages. The water immersion type scraper slag conveyer is hung in the slag bin, and the slag water drainage treatment is realized. The difficulty of drainage is greatly reduced, the ground is not waterlogged and the slag is not stacked, a good environment and premise are provided for the slag car to be smoothly and accurately positioned and connected to the slag, the slag water in the slag bin is mostly separated and drained, and is discharged into the designated slag water ditch through the drainage pipe. The effect of small design realizing large effect is achieved.

[0048] The utility model has good drainage effect, can avoid water entering the bin due to a large amount of ash and slag, reduce the load of the slag bin and improve the drainage pressure of the slag bin, and has stronger adaptability to the coal kind of the boiler, and reduces the coal cost of the power plant.

[0049] The above is only the preferred embodiment of the utility model, and is not used for limiting the utility model. For those skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
