DETAILED DESCRIPTION

[0026] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: an anti-deposition spiral sludge dewatering machine, comprising a base 1, a shell 7, and a mud inlet 36.

[0029] The filter assembly 10 includes three groups of connecting plates 12, and six groups of connecting rods 13 are fixedly connected between two adjacent groups of connecting plates 12 and between the connecting plates 12 and the shell 7.

A moving plate 15 is arranged in the active cavity. A gap is formed between the moving plate 15 and the static plate 14 for filtering the sludge water.

[0030] The left side of the shell 7 is provided with three groups of mud outlets 16, and the three groups of mud inlets 36 are respectively located on the right sides of the three groups of connecting shells 4, and the lower side of the connecting shell 4 is fixedly connected with a mud receiving plate 34;

[0031] Four sets of sliding columns 17 are fixedly connected to the left outer wall of the three sets of mud outlets 16, and a back pressure plate 18 is slidably connected to the sliding columns 17;

[0032] Four sets of hydraulic telescopic cylinders 19 are fixedly connected to the side of the back pressure plate 18 away from the housing 7, and the four sets of hydraulic telescopic cylinders 19 are fixedly connected to the left inner wall of the connecting shell 4;

[0033] The left side of the rotating shaft of the three sets of spiral stacks 9 passes through the housing 7, the back pressure plate 18, the connecting shell 4 and the drive assembly 5 are connected by gears, and the four sets of hydraulic telescopic cylinders 19 are distributed at 90 degrees with the rotating shaft axis of the spiral stack 9 as the center.

[0034] The driving assembly 5 includes a gear box 20 , and a driving motor 21 is fixedly connected to the upper side of the gear box 20 . The output end of the driving motor 21 is connected to the rotating shaft gear of the spiral stack 9 through the gear box 20 .

[0035] The flocculation stirring assembly 3 includes a support frame 22, a stirring box 23 is fixedly connected to the upper side of the support frame 22, a mud inlet box 24 is fixedly connected to the right side of the stirring box 23, a mud inlet chamber 25 and a drug adding chamber 26 are respectively provided in the mud inlet box 24, the mud inlet chamber 25 is located on the right side of the drug adding chamber 26, and a notch 27 is provided between the mud inlet chamber 25 and the drug adding chamber 26 to facilitate the sludge water in the mud inlet chamber 25 to enter the drug adding chamber 26;

[0036] The lower side of the dosing chamber 26 is connected to the stirring box 23, and the inner wall of the front side of the dosing chamber 26 is connected to a dosing pipe 28, and the input end of the dosing pipe 28 is connected to a dosing device, which is an existing dosing device for sludge dehydration and flocculation;

[0037] The lower side of the mud inlet chamber 25 is connected with a mud inlet pipe 29 and an overflow pipe 30 respectively. The overflow pipe 30 passes through the mud inlet box 24 and the input end is located at the upper side of the mud inlet chamber 25 and higher than the bottom side of the notch 27, so as to prevent mud and water in the mud inlet chamber 25 from escaping.

[0038] A fixed plate 31 is fixedly connected to the upper side of the mixing box 23, a rotating motor 32 is fixedly connected to the upper side of the fixed plate 31, an output end of the rotating motor 32 passes through the fixed plate 31 and is fixedly connected to an agitator 33, and the upper left side of the mixing box 23 is connected to a mud inlet 36 through a pipeline.

[0039] In this embodiment, the sludge water enters the sludge inlet chamber 25 through the sludge inlet pipe 29, and enters the dosing chamber 26 through the notch 27. At this time, the dosing device adds medicine into the dosing chamber 26, and the sludge water after the dosing enters the stirring chamber through the lower side of the dosing chamber 26. Under the action of the stirrer 33, the sludge water condenses into flocs.

[0040] Then, the flocculent sludge water enters the cavity formed by the filter assembly 10 and the spiral disc 9 through the pipeline from the mud inlet 36, and the driving assembly 5 is started to drive the spiral disc 9 to rotate. The spiral disc pushes the moving disc 15 in the filter assembly 10 in a spiral manner, so that the water in the sludge penetrates into the water collection tank 6 through the gap between the moving disc 15 and the static disc 14, and flows out from the outlet pipe 8;

[0041] The filtered sludge continues to move toward the mud outlet 16 under the rotation of the spiral stack 9. When the filtered sludge water reaches a certain level, the sludge accumulates at the left end of the spiral stack 9. When a certain pressure is reached, the sludge is forced to squeeze out from the gap between the back pressure plate 18 and the mud outlet 16, falls on the mud receiving plate 34 and enters the collection box.

[0042] When the density of sludge in the sludge water is too high and accumulates at the end of the spiral stack 9, causing the rotation speed of the spiral stack 9 to decrease, the hydraulic telescopic cylinder 19 is controlled to retract, so that the gap between the back pressure plate 18 and the mud outlet 16 becomes larger, thereby improving the mud discharge efficiency at the end of the spiral stack 9 and preventing excessive accumulation of sludge at the end of the spiral stack 9.

[0044] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
