[0002] In the field of hazardous waste treatment, especially in the wet slag removal process of rotary kilns, traditional slag treatment methods often have problems such as low water removal efficiency, high energy consumption, complex operation and easy to cause secondary pollution. Traditional water removal equipment mostly uses static filtration or simple mechanical extrusion methods, which is not only difficult to effectively separate the water in hazardous waste slag with high water content, but also easily causes equipment blockage, affecting treatment efficiency. In addition, these methods often require a large amount of energy, such as heat energy, electricity, etc., to accelerate water evaporation or slag drying, which not only increases the treatment cost, but may also cause additional burden on the environment due to energy consumption and emission problems in the treatment process. Therefore, the development of an efficient, energy-saving and environmentally friendly slag dewatering technology has become a key issue that needs to be urgently addressed in the field of hazardous waste treatment.

[0003] In the existing technology, during the use of slag dewatering, there are operational problems such as low dewatering efficiency, easy clogging, and relatively high energy consumption; therefore, we have made improvements to this and proposed a slag dewaterer for wet slag removal in hazardous waste rotary kilns.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0028] like Figure 1-6As shown, this embodiment proposes a slag dewatering device for wet slag removal of hazardous waste rotary kiln, including a dewatering bin 1, a linkage motor 2 is provided at the upper end of the dewatering bin 1, a threaded rod 3 is provided at the lower end of the linkage motor 2, a linkage plate 4 is provided at the outer end of the threaded rod 3, a linkage block 5 is provided at the outer end of the linkage plate 4, a dewatering net 6 is provided at the lower end of the linkage plate 4, a first folding net 7 and a second folding net 8 are provided at both ends of the dewatering net 6, an arc-shaped rack 12 is provided at the outer ends of the first folding net 7 and the second folding net 8, an inner rack 9 and an outer rack 10 are provided at the outer ends of the inner rack 9 and the outer rack 10, an arc-shaped groove is provided, a rotating motor 11 is provided between the inner rack 9 and the outer rack 10, a magnetic suction groove 13 is provided at the inner end of the first folding net 7, and a magnetic block 14 is provided at the outer end of the second folding net 8.

[0029] The lower end of the linkage motor 2 is movably connected to the threaded rod 3 , the outer end of the threaded rod 3 is threadedly connected to the threaded plate, and the outer end of the threaded plate is fixedly connected to the linkage block 5 .

[0030] The rotation of the linkage motor 2 drives the threaded rod 3, which in turn moves up and down through the threaded plate. This structure ensures uniform compression of the slag, accelerates the separation of water, and avoids direct physical damage to the slag, preserving its physical properties.

[0031] The outer end of the linkage block 5 is provided with a slide groove, which is embedded in the inner end of the dewatering bin 1. The upper end of the dewatering net 6 is provided with a sliding frame. The center of the sliding frame is wrapped around the outer end of the threaded rod 3, and the sliding frame moves inside and outside the dewatering bin 1.

[0032] The sliding frame is wrapped around the outer end of the threaded rod 3 and moves along the inner wall of the dewatering tank 1, ensuring the stability and operability of the dewatering net 6 during the dewatering process. The cooperation between the linkage block 5 and the chute allows the dewatering net 6 to be evenly distributed when subjected to force, improving the dewatering efficiency and the service life of the equipment.

[0033] The two ends of the dewatering net 6 are fixedly connected to the first folding net 7 and the second folding net 8 respectively. The first folding net 7 and the second folding net 8 are meshed and connected with the inner rack 9 and the outer rack 10 through the arc-shaped rack 12.

[0034] The fixed connection between the dewatering net 6 and the first and second folding nets 7 and 8 enables the automatic expansion and contraction of the folding nets through the meshing of the arc-shaped rack 12 with the inner and outer racks 9 and 10. This design not only improves the efficiency of the dewatering device but also ensures the stability of the slag during the filtration process, preventing slag from clogging the dewatering net 6.

[0035] Positioning shafts are provided at both ends of the arc groove, and the inner rack 9 and the outer rack 10 are rotationally connected via a rotating motor 11.

[0036] The rotating motor 11 drives the inner rack 9 and the outer rack 10 to move along the positioning axis, realizing the automatic expansion and contraction of the first folding net 7 and the second folding net 8. This design not only simplifies the operation process, but also improves the degree of automation of the equipment, reduces manual intervention, and improves work efficiency.

[0037] The first folding net 7 and the second folding net 8 are magnetically connected via the magnetic groove 13 and the magnetic block 14 .

[0038] The first folding net 7 and the second folding net 8 are magnetically connected through the magnetic groove 13 and the magnetic block 14, ensuring that the folding nets can fit tightly during the slag dehydration process to prevent slag leakage. At the same time, after the dehydration is completed, they can be quickly and conveniently separated for easy cleaning and maintenance.

[0039] The linkage motor 2, through the threaded rod 3, pushes the threaded plate downward through the interaction between the linkage block 5 and the chute, compressing the air inside and accelerating the slag dewatering process. This design utilizes physical principles, eliminating the need for additional energy input and achieving efficient and energy-saving dewatering.

[0040] When the present application is in use: During the use of the slag dehydrator, the dehydration net 6 is first installed in the dehydration bin 1 through the sliding frame, and the rotating motor 11 is started to drive the inner rack 9 and the outer rack 10 in the arc groove to move along the positioning axis, pushing the arc rack 12 connected to the first folding net 7 and the second folding net 8 at both ends to move until the first folding net 7 and the second folding net 8 are adsorbed on each other through the magnetic suction groove 13 and the magnetic block 14, and the slag mixture is poured onto the dehydration net 6 in the dehydration bin 1, and the water is filtered through the dehydration net 6, and the threaded rod 3 linked by the linkage motor 2 above pushes the threaded plate downward under the interaction of the linkage block 5 and the slide groove, so as to compress the internal air and accelerate the dehydration of the slag.

[0041] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
