[0048] The working principle of the present application is as follows:

[0049] 1, detect the concentration of sludge: when the sewage from the feed inlet 11 into the dehydration tank 1, sewage will flow in the feed inlet 11, by the setting of the inclined plane plate 401, sludge flow together in the process of gathering, the setting of the light lamp 402 will open and shine light into the feed inlet 11, the light emitted by the light will penetrate the flowing sludge in the feed inlet 11, the light transmittance detection element 404 will measure the light intensity after penetration, in the process of light penetrating the sludge, part of the light is absorbed or blocked by the sludge, part of the light is scattered, and the remaining light is the final light penetrating the sludge, because the sludge will affect the propagation path and intensity of light, so the final light penetrating the sludge will be smaller than the original incident light intensity, at this time, the light transmittance detection element 404 will record the light intensity penetrating the sludge, and further judge the transparency and concentration of the sludge, the light penetrating the sludge will be detected by the light transmittance detection element 404, (the function of the light transmittance detection element 404 is to convert the optical signal into electrical signal, the photon (light particle, light penetrating the sludge) interacts with the substance in the light transmittance detection element 404, resulting in the release or flow of electric charge, thereby generating an electrical signal proportional to the light intensity), and the water content in different sludge is different, the light intensity of light penetrating the sludge is different, therefore, different light intensity will produce different electrical signals, and the controller will drive the third telescopic driving part 211 to make different output actions through different electrical signals, when the electrical signal is strong, it represents that the water content in the sludge is relatively small (low sludge concentration), the telescopic end of the third telescopic driving part 211 will be driven to extend, when the electrical signal is weak, it represents that the water content in the sludge is relatively large (high sludge concentration), the telescopic end of the third telescopic driving part 211 will be driven to retract;

[0050] Adjust the size of the dehydration gap to facilitate the removal of sewage: in the process of retracting the telescopic end of the third telescopic driving part 211, the third telescopic driving part 211 will drive the sliding plate 214 to retract in the hydraulic cylinder 213, and the hydraulic oil in the oil storage space, the small rubber sleeve 204 and the large rubber sleeve 205 will be pumped back to the hydraulic cylinder 213 through the first conveying pipe 208 and the rotating joint 207, so as to increase the dehydration gap; in the process of extending the telescopic end of the third telescopic driving part 211, the third telescopic driving part 211 will drive the sliding plate 214 to slide in the hydraulic cylinder 213 and extrude the hydraulic oil in the hydraulic cylinder 213, the extruded hydraulic oil will be conveyed to the small rubber sleeve 204 and the large rubber sleeve 205 through the first conveying pipe 208 and the rotating joint 207 through the oil storage space, so as to expand the small rubber sleeve 204 and the large rubber sleeve 205, and reduce the dehydration gap;

[0051] In general, the concentration of sludge is proportional to the light transmittance detection element 404 to detect the generated electrical signal, and the controller controls the third telescopic drive 211 to extend and retract the telescopic end, so that the sliding plate 214 moves in the hydraulic cylinder 213. The amplitude is proportional to the generated electrical signal detected by the light transmittance detection element 404. Before the sludge enters the dewatering tank 1, the dewatering gap is standard size. When the above detection detects that the concentration of sludge is too high or too low, the dewatering gap will be adjusted on the basis of the standard size of the dewatering gap. (When the water content in the sludge is high, appropriately increasing the dewatering gap can prevent blockage due to poor sludge flowability and ensure that the moisture can be smoothly discharged. When the concentration of sewage is low, reducing the gap helps improve dewatering efficiency and reduce the risk of sewage leakage.) Similarly, the hardness (deformability) of the small rubber sleeve 204 and the large rubber sleeve 205 gradually increases along the direction of sludge flow. The initial standard hardness of the small rubber sleeve 204 and the large rubber sleeve 205 is adapted to the standard of the dewatering gap. When the dewatering gap is not driven to change by the hydraulic pressure of the hydraulic oil, the initial standard hardness of the small rubber sleeve 204 and the large rubber sleeve 205 is adapted to the standard of the dewatering gap. During the process of increasing or decreasing the water content in the sludge, the hydraulic pressure of the hydraulic oil acts on the small rubber sleeve 204 and the large rubber sleeve 205 to increase or decrease the expansion degree due to the difference in hardness.

[0052] 2. Separate sewage: When the sludge flows in the dewatering tank 1 according to the direction of sludge flow, the driving motor 216 drives the short shaft 203 to rotate and drives the feeding shaft 202 to rotate (the feeding shaft 202 is connected by a belt drive, and the rotation direction is consistent), and the extrusion strip 206 set will move with the feeding shaft 202 to the position of the feeding port 11. The sludge will first pass through the position with a smaller dewatering gap. When the sludge is continuously flowing, the position with a smaller dewatering gap will first filter out the sewage in the sludge, and the position with a larger dewatering gap set by the feeding shaft 202 will accelerate the filtration efficiency of the sewage in the sludge. At the same time, the rotating feeding shaft 202 and the extrusion strip 206 will increase the friction with the sludge during the movement of the sludge to drive the sludge tank feeding port 11 to move and discharge;

[0053] In the process of sludge moving, the rotating head 305, the transverse plate 306, the support plate 307, the mounting frame 308 and the extrusion plate 309 are driven to descend by opening the first telescopic driving part 302 (one end of the extrusion plate 309 is fixedly connected with the linkage sliding plate 320 through the rotating shaft 310 and has been driven to descend by the second telescopic driving part 304, and a gap is formed between the extrusion plate 309 and the feeding shaft 202, so that in the process of driving the other end of the extrusion plate 309 to descend, the extrusion plate 309 rotates and descends with the rotating shaft 310 as the center, and when the content of sewage in the sludge is relatively large, the sludge amount to be passed through in unit time is relatively large, and under the premise that the sludge meets the dewatering requirement, the second telescopic driving part 304 drives the one end of the extrusion plate 309 to ascend or descend, so that the sludge flow through the flow gap in unit time can be increased or decreased), the extrusion plate 309 descending cooperates with the feeding shaft 202 to extrude the sludge, and the extruded sludge can make the sewage flow out of the dewatering gap, and in the process of descending of the extrusion plate 309, the long plate 314 is driven to descend, and the plurality of long plates 314 drive the separation head 315 to descend into the gap between the feeding shaft 202, so that in the process of extruding the sewage by the extrusion plate 309, the separation head 315 with the number decreasing in turn can separate the sludge, so that the sludge cannot be adhered together at the beginning of moving on the feeding shaft 202 and cannot be effectively separated from the water in the sludge when being extruded by the descending extrusion plate 309.

[0054] In the process of driving the extrusion plate 309 to descend, the separation head 315 and the long plate 314 can contact the feeding shaft 202, and as the extrusion plate 309 continuously descends, the long plate 314 and the arc-shaped sealing plate 312 can slide in the lifting column 313, drive the sliding shaft 317 to slide in the groove 318, the groove 318 is arranged in a curved shape, the sliding shaft 317 sliding in the inner wall can drive the arc-shaped sealing plate 312, the long plate 314 and the separation head 315 to reciprocate in the gap of the feeding shaft 202, stir the sludge, prevent the sludge from adhering together in the early stage of conveying on the feeding shaft 202, and cause the water in the sludge to be unable to be effectively separated.

[0055] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the same; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present application.
