[0021] like Figures 1 and 2As shown, this embodiment provides a sludge scraping mechanism at the sludge inlet of a belt dewatering machine, comprising a scraper plate 2 arranged above the sludge conveyor belt 1 at the sludge inlet of the belt dewatering machine, the end of the scraper plate being hinged to a frame 3, and a fastener for tightening and loosening is connected between the end of the scraper plate and the frame, so as to facilitate the scraper plate to swing up and down along the hinge point to adjust the distance between the scraper plate and the sludge conveyor belt.

[0022] In an embodiment of the present invention, the length direction of the scraper blade is the width direction of the sludge conveyor belt.

[0023] In the embodiment of the present utility model, both ends of the scraper blade are hinged to the frame via a hinge shaft 4 .

[0024] In an embodiment of the present invention, the fastener includes a screw 5 and a nut 6. The screw is fixedly connected to the frame. The end of the scraper is provided with an arc-shaped groove 7 with its hinge axis as the center. The screw is locked with a nut after passing through the groove.

[0025] In the embodiment of the present invention, the scraper is provided with a plurality of stiffening ribs 8 on the back side of its scraping surface to improve the rigidity of the scraper.

[0026] In an embodiment of the present invention, a mud rake assembly located above the mud conveyor belt is provided on the back side of the scraper blade.

[0027] In the embodiment of the present invention, the mud rake assembly is composed of several groups of rod-shaped mud rake assemblies 9 and several groups of triangular mud rake assemblies 10, which are spaced apart from each other in sequence from front to back along the mud conveying direction.

[0028] In the embodiment of the present utility model, the rod-shaped mud rake assembly includes an angle iron 11 fixedly connected to the frame, and a number of axially vertical sleeves 12 are evenly fixed on the side of the angle iron along the width direction of the sludge conveyor belt. Vertical rods 13 are coaxially inserted inside the sleeves, and the vertical rods are radially tightened by set screws 14 threaded on the sleeves, and the bottom ends of the vertical rods are all conical ends with the tips facing downwards for contacting the sludge.

[0029] In the embodiment of the present utility model, the triangular mud rake assembly includes a connecting rod 15 fixedly connected to the frame, and a number of triangular comb teeth 16 with the tips facing forward are evenly fixed on the side of the connecting rod along the width direction of the mud conveyor belt for contacting the mud, and there is a gap between the triangular comb teeth and the mud conveyor belt.

[0031] In the embodiment of the utility model, the working principle of the sludge inlet scraping mechanism of the belt dewatering machine is as follows: by adjusting the distance between the scraper blade and the sludge conveyor belt, sludge spread on the sludge conveyor belt that is thicker than the distance can be scraped off, thereby thinning the sludge entering the belt dewatering machine and improving the dewatering effect. When adjusting the scraper blade, the upward and downward swing angle of the scraper blade is changed by loosening the nut, thereby adjusting the distance between the scraper blade and the sludge conveyor belt.

[0032] After the silt spread on the silt conveyor belt is thinned by the scraper, the silt continues to be transported from front to back and passes through the rod-shaped raking mud assembly, the triangular raking mud assembly, the rod-shaped raking mud assembly, the triangular raking mud assembly, and the rod-shaped raking mud assembly in turn. The silt is raked by the vertical pole and the triangular comb teeth to form loose mud, avoiding the silt from being loose enough, which can improve the subsequent dehydration effect.
