Detailed implementation manners

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] As Figure 1 shown, a river dredging and fertilizer making system includes a plate and frame filter press 1, a silo 2, a drying platform 3 and a mixing mechanism 4.

[0031] As Figure 1 shown, the plate and frame filter press 1 is horizontally arranged on the ground and is used for dewatering the sludge. The silo 2 is connected in series behind the plate and frame filter press 1 and is used for storing the dewatered mud blocks.

[0032] As Figure 1 , Figure 2 shown, the silo 2 includes a silo body 21, a crushing slurry 22 and a discharge pipe 23. The silo body 21 is vertically arranged. The crushing slurry 22 is horizontally rotatably connected below the silo body 21 to realize the preliminary crushing of large mud blocks. The discharge pipe 23 is obliquely arranged on the lower side wall of the silo body 21. The cross-section at the middle position of the discharge pipe 23 is circular, and a rotating shaft 24 is horizontally rotatably connected inside. A plurality of baffles 25 are arranged on the outer wall of the rotating shaft 24.

[0033] As Figure 1 、 Figure 3 shown, the drying platform 3 is connected to the silo 2 and is used to support the mud blocks and expose them to the sun. The drying platform 3 includes a conveyor belt 31, trays 32, springs 33 and vibration balls 34. The conveyor belt 31 is horizontally arranged on the ground, the trays 32 are arranged on the conveyor belt 31, the springs 33 are arranged on both sides of the conveyor belt 31, and the vibration balls 34 are arranged on the springs 33 and are used to impact the side walls of the trays 32.

[0034] As Figure 1 、 Figure 4 shown, the mixing mechanism 4 is connected behind the drying platform 3 and is used to fully mix the mud blocks and straw. The mixing mechanism 4 includes a mixing barrel 41, a sludge crusher 42 and a straw crusher 43. A stirring paddle 5 is vertically rotatably connected in the mixing barrel 41, and the sludge crusher 42 and the straw crusher 43 are respectively connected to the mixing barrel 41.

[0035] When sludge needs to be processed, the sludge is put into the plate and frame filter press 1, and the plate and frame filter press 1 is used to extrude and dehydrate the sludge. Subsequently, the dehydrated mud blocks are transported into the silo 2 for storage. Then, control the rotation of the crushing slurry 22 to realize the crushing of the mud blocks, and control the intermittent rotation of the rotating shaft 24, so that the rotating shaft 24 drives the baffle 25 to move synchronously, so that the mud blocks carried between adjacent two baffles 25 can slide out along the discharge pipe 23, completing the intermittent discharging of the mud blocks in the bin body 21.

[0036] When the mud blocks in the silo 2 are being unloaded, control the conveyor belt 31 to drive all the trays 32 to rotate, so that the trays 32 move to the lower part of the discharge pipe 23, thereby pouring the mud blocks into the trays 32 for drying. And when the trays 32 are moving, under the action of the springs 33 and the vibration balls 34, the vibration balls 34 impact the trays 32, so that the mud blocks in the trays 32 are automatically and evenly spread over the trays 32, facilitating full exposure to the sun.

[0037] When the tray 32 moves to the end position of the conveyor belt 31, the tray 32 will automatically turn over and pour the sun-dried mud blocks into the sludge crusher 42 to realize the complete crushing of the mud blocks. At the same time, put the straw blocks into the straw crusher 43 to realize the complete crushing of the straw. Subsequently, the crushed mud blocks and straw are all put into the mixing barrel 41, and control the rotation of the stirring paddle 5 to realize the full stirring and mixing of the mud blocks and straw, realizing the production and processing of fertilizers.

[0038] Therefore, by setting up a highly continuous fertilizer production system, the automatic dehydration, drying and mixing of sludge can be realized, and the continuous production and automatic processing of sludge into fertilizers can be realized, thereby effectively improving the treatment efficiency of sludge.

[0039] As Figure 5 、Figure 6 As shown, an annular water injection pipe 6 is provided on the inner wall at the upper end of the stirring barrel 41. The water injection pipe 6 includes a pipe body 61, an annular body 62, and a driving member 64. The cross-section of the pipe body 61 is U-shaped and is arranged with the opening facing downward. The annular body 62 is rotatably connected to the opening position of the pipe body 61, and a nozzle 63 is vertically communicated on the annular body 62.

[0040] As Figure 5 、 Figure 6 shown, the driving member 64 is used to control the rotation of the annular body 62. The driving member 64 includes a motor 65, a gear 66, and a toothed ring 67. The motor 65 is arranged in the stirring barrel 41, the gear 66 is arranged on the motor 65, the toothed ring 67 is arranged on the annular body 62, and is meshed with the gear 66.

[0041] When the stirring barrel 41 works, clean water is injected into the water injection pipe 6, and then the motor 65 is used to control the slow rotation of the gear 66. The gear 66 drives the toothed ring 67 and the annular body 62 to move synchronously, and the annular body 62 drives the nozzle 63 to rotate in the circumferential direction, realizing the circular spraying and uniform spraying of the materials in the stirring barrel 41, achieving the full mixing of the mud blocks and straws, and forming a viscous mud paste, which is convenient for packing and use.

[0042] As Figure 5 、 Figure 7 shown, the stirring paddle 5 includes a rod body 51, a vertical pipe 52, and paddle blades 53. The rod body 51 is vertically and rotatably connected in the stirring barrel 41. The vertical pipe 52 is vertically and slidably connected to the rod body 51. The paddle blades 53 are arranged on the outer wall of the vertical pipe 52. A spline 54 is arranged on the outer wall of the rod body 51, and a key groove 55 is arranged on the inner wall of the vertical pipe 52.

[0043] As Figure 5 、 Figure 7 shown, a linkage mechanism 56 for controlling the vertical sliding of the vertical pipe 52 is arranged on the vertical pipe 52. The linkage mechanism 56 includes a guide rod 57 and a guide rail 58. The guide rod 57 is arranged on the outer wall at the upper end of the vertical pipe 52. The guide rail 58 is arranged on the inner wall of the stirring barrel 41 and is arranged in a wavy shape. The end position of the guide rod 57 is embedded in the guide rail 58.

[0044] When the stirring paddle 5 works, the rod body 51 is controlled to rotate. At this time, under the cooperation of the spline 54 and the key groove 55, the rod body 51 drives the vertical pipe 52 to rotate synchronously, and the paddle blades 53 are used for stirring. When the vertical pipe 52 rotates, the vertical pipe 52 drives the guide rod 57 to move synchronously. At this time, under the cooperation of the guide rod 57 and the guide rail 58, the vertical pipe 52 jumps along the vertical direction, so as to realize the full stirring and mixing between the silt and the straw, and improve the quality of the fertilizer.

[0045] The specific embodiments are only explanations of the present invention and do not limit the present invention. After reading this specification, those skilled in the art can make modifications to these embodiments without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
