However, a large amount of silt will be generated during the management process. If various silt solidification methods are used, a large amount of financial resources will be required, and the subsequent harmless disposal of the solidified soil is also a huge and arduous project. If the traditional natural sedimentation and drying method is used, it will take at least three to four years. The waste rate of land resources is extremely high, so a silt physical dehydration function device is needed.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, a sludge physical dehydration functional device includes a box body 1, a crushing mechanism 3 is fixedly connected to the front side of the upper end of the box body 1, a water filtering mechanism 4 is fixedly connected to the front side of the middle part of the inner cavity of the box body 1, an extrusion mechanism 5 is fixedly connected to the rear side of the middle part of the inner cavity of the box body 1, a drainage board 6 is fixedly connected to the front side of the lower side of the inner cavity of the box body 1, and a water storage mechanism 2 is fixedly connected to the rear side of the right end of the outer surface of the box body 1.

[0026] The utility model is implemented in a specific manner. First, the internal driving structure of the crushing mechanism 3 is started, and then the silt in the sludge discharge field is transported to the inside of the crushing mechanism 3. Under the action of the crushing mechanism 3, the block particles contained in the silt can be crushed. At the same time, the internal structure of the water filtering mechanism 4 is started, driving the silt to move slowly backward on the surface of the water filtering mechanism 4. The silt is evenly scraped apart by the water filtering mechanism 4, so that more water contained in the silt begins to seep out. The naturally seeping water falls on the drain plate 6 through the action of the water filtering mechanism 4, and then the water flows into the water storage mechanism 2 through the downward inclination of 5 to 10 degrees at the rear of the drain plate 6. When the silt on the surface of the water filtering mechanism 4 moves to the inside of the squeezing mechanism 5, the silt is squeezed multiple times by the action of the squeezing mechanism 5, which greatly reduces the water content of the silt and makes the water fall directly into the water storage mechanism 2. The silt that has been squeezed multiple times is in the form of a dry mud cake and is sent out from the rear of the squeezing mechanism 5 for subsequent treatment. The water that flows into the water storage mechanism 2 is pumped out and discharged to the drain ditch and back to the river by starting the internal structure of the water storage mechanism 2.

[0027] Specifically, in order to achieve the purpose of crushing silt, refer to Figure 2In this solution, the crushing mechanism 3 includes a support seat 37 and a baffle 34. The support seat 37 is fixedly connected to the front side of the upper end of the box body 1, and the middle part of the lower end of the support seat 37 is fixedly connected to the discharge port 38. The middle part of the upper end of the support seat 37 is fixedly connected to the crushing barrel 31, and the middle part of the upper wall of the inner cavity of the crushing barrel 31 is fixedly connected to a spiral sheet 35. A plurality of scrapers 36 are fixedly connected to the annular array on the outer surface of the spiral sheet 35. The middle part of the upper end of the crushing barrel 31 is fixedly connected to a motor 32, and the upper part of the front side of the outer arc surface of the crushing barrel 31 is fixedly connected to the feed port 33. The support seat 37 has a plurality of through holes 39 in the middle part of the upper end, and the baffle 34 is fixedly connected to the upper side of the front wall of the inner cavity of the box body 1.

[0028] Furthermore, the output end of motor 1 32 passes through the upper end of the crushing barrel 31 and is fixedly connected to the upper end of the spiral piece 35 through a coupling. Several through holes 39 are connected to the lower end of the crushing barrel 31 and the upper end of the discharge port 38 on the same side.

[0029] In the above, the silt extracted from the river channel is directly fed into the crushing barrel 31 from the feed port 33, and the spiral blade 35 is driven to rotate by the starting motor 32 to transport the silt downward. While the spiral blade 35 rotates, the large particles or block materials contained in the silt can be crushed by the provided scraper 36, and then enter the water filtration mechanism 4 through the through hole 39 and the discharge port 38.

[0030] The specific installation method, circuit connection method and control method of the motor 32 used in the above are all conventional designs. During the implementation process, it is only necessary to drive the spiral piece 35 to rotate, and the utility model will not elaborate on them in detail.

[0031] Specifically, in order to achieve the purpose of evenly spreading the sludge inside the device, refer to Figure 3 In this solution, the water filtering mechanism 4 includes two rollers 41 and a support block 45. The two rollers 41 are rotatably connected to the upper middle side and the upper front side of the inner cavity of the box body 1 respectively. The outer surfaces of the two rollers 41 are commonly wrapped with a filter belt 42. The support block 45 is fixedly connected to the upper middle side of the right end of the box body 1. The upper end of the support block 45 is fixedly connected to a motor 2 46. The output end of the support block 45 passes through the right end of the box body 1 and is fixedly connected to the right end of the roller 41 on the rear side through a coupling. Two support plates 43 are fixedly connected to the front of the inner cavity of the box body 1 at intervals. The lower ends of the two support plates 43 are fixedly connected to a number of triangular columns 44 in a rectangular distribution. A baffle 2 48 is fixedly connected to the upper middle side of the inner cavity of the box body 1.

[0032] In the above, the silt slides onto the surface of the filter belt 42 through the baffle 34, and the roller 41 is driven to rotate by the starting motor 46, and the filter belt 42 is driven to rotate by the roller 41, so that the silt slowly starts backward, and then passes through the filter belt 42 made of non-woven fabric. During the movement, the silt is evenly scraped apart by the triangular column 44, so that the silt contains more water and begins to seep out from the surface of the filter belt 42 and flow downward to the top of the drainage board 6, and then flows into the water storage mechanism 2 through the drainage board 6.

[0033] The specific installation method, circuit connection method and control method of the motor 2 46 used in the above are all conventional designs. During the implementation process, it is only necessary to drive the roller 1 41 to rotate, and the present invention will not elaborate on them in detail.

[0034] Specifically, in order to achieve the purpose of solidifying the sludge without causing any pollution, refer to Figure 4 In this solution, the extrusion mechanism 5 includes several rollers 51 and several rollers 53. Several rollers 51 are rotatably connected to the middle of the rear side of the inner cavity of the box body 1, and several rollers 53 are rotatably connected to the upper part of the rear side of the inner cavity of the box body 1. The outer surfaces of several rollers 51 are commonly wrapped with filter belts 52, and the outer surfaces of several rollers 53 are commonly wrapped with filter belts 3 54. The right ends of rollers 2 51 and rollers 3 53 located on the rear side pass through the right wall of the inner cavity of the box body 1 and extend to the outside. The right ends of rollers 2 51 and rollers 3 53 located on the rear side are fixedly connected to gears 57. The upper side of the rear right end of the box body 1 is fixedly connected to a support block 2 55, and the upper end of the support block 2 55 is fixedly connected to a motor 3 56.

[0035] Furthermore, several rollers 2 51 and several rollers 3 53 are arranged in an S shape, the outer surfaces of the two gears 57 are meshed and connected, the output end of motor 3 56 is fixedly connected to the right end of the lower gear 57 through a coupling, and a scraper 58 is fixedly connected to the upper rear side of the inner cavity of the box body 1.

[0036] In the above, by starting motor three 56, roller two 51 and roller three 53 are driven to rotate in opposite directions under the action of two gears 57, and then roller two 51 and roller three 53 drive filter belt two 52 and filter belt three 54 to rotate in opposite directions, and then the silt slides evenly from the surface of baffle two 48 to the surface of filter belt two 52, and the rotation of filter belt two 52 drives the silt to enter between filter belt two 52 and filter belt three 54. The arrangement of roller two 51 and roller three 53 can squeeze the silt multiple times. Since the surfaces of filter belt two 52 and filter belt three 54 are both made of non-woven fabric, the squeezed water falls directly into the water storage mechanism 2. When the silt is squeezed multiple times, the moisture content in the silt is greatly reduced, and the silt is solidified, and then it can be discharged directly from the upper surface of the scraper 58 without adding any chemical agents, effectively protecting the integrity of the surrounding ecosystem.

[0037] The specific installation method, circuit connection method and control method of the motor 3 56 used in the above are all conventional designs. During the implementation process, it only needs to be able to drive the roller 2 51 and the roller 3 53 to rotate, and the utility model will not elaborate on them in detail.

[0038] Specifically, in order to discharge the squeezed water, refer to Figure 4 In this solution, the water storage mechanism 2 includes a water tank 23 and a fixed block 21. The water tank 23 is fixedly connected to the rear side of the bottom wall of the inner cavity of the box body 1, and the fixed block 21 is fixedly connected to the lower part of the rear right end of the box body 1. The upper end of the fixed block 21 is fixedly connected to a water pump 22, and the input end of the water pump 22 passes through the outer surface of the box body 1 and is fixedly connected to the right end of the water tank 23.

[0039] In the above, the water falling from the surface of the filter belt 42 will slide directly into the inner cavity of the water tank 23 through the drainage plate 6, and then pass through the external water pipe to the output end of the water pump 22. The water pump 22 is started to extract the water inside the water tank 23 and discharge it back into the river.

[0040] In the above, the mud field is an important environmental protection facility, which is mainly used to treat waste or pollutants containing a large amount of solid particles such as mud and sludge. The mud field is generally rectangular or square. The size of the mud field can be adjusted according to needs. It can be as small as dozens of acres or as large as hundreds or thousands of acres. The bottom of the mud field can be tilted 5 to 10 degrees toward the device, and then the sludge inside the mud field is pumped by an external water pump and sent into the device from the feed port 33 for dehydration treatment.

[0041] It should be noted that the specific installation method of the water pump 22, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
