DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0023] Reference Figure 1-Figure 7 , a comprehensive sediment treatment method for a water conservancy project comprises the following steps: Step 1: Move the treatment equipment to the location of the sediment to be treated, and pump the sediment into the treatment equipment through a thick slurry pump; Reference Figure 1-Figure 3The processing equipment includes a processing box 1 and a feed hopper 2. The feed hopper 2 is connected to the top of the processing box 1. The interior of the processing box 1 is provided with a floating object collection unit, a filtering unit and a dehydration unit, which are respectively used to collect floating objects and stones in the sediment and to preliminarily separate the sediment from the processing box 1.

[0024] It should be explained that the silt is usually extracted by a slurry pump, and the output end of the slurry pump can be placed in the feed hopper 2 to achieve the addition of silt. The staff can adjust the number of slurry pumps according to the situation to achieve the best working state of the processing box 1.

[0025] Step 2: The treatment equipment can stir the sediment to separate the floating objects attached to the sediment from the sediment; Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The floating object collecting unit includes two groups of stirring members 5. A motor 3 connected to the stirring member 5 is fixedly connected to the outer wall of the processing box 1. A rotating shaft 4 connected to the output end of the motor 3 is rotatably connected to the inner wall of the processing box 1. The stirring member 5 is fixedly connected to the rotating shaft 4. The ends of the two groups of rotating shafts 4 away from the motor 3 are fixedly connected with mutually meshing linkage gears 6. A salvaging mechanism linked to the rotating shaft 4 is arranged inside the processing box 1 for salvaging floating objects in the mud and sand. The stirring member 5 includes a mounting cylinder 51 fixedly connected to the rotating shaft 4. A plurality of groups of stirring rods 52 are fixedly connected to the mounting cylinder 51. An air storage ring 53 is provided inside the mounting cylinder 51. A plurality of groups of spray holes 54 connected to the air storage ring 53 are provided on one side of the mounting cylinder 51 close to the stirring rod 52. The stirring rods 52 on the two groups of mounting cylinders 51 cooperate with each other, and the spray holes 54 are respectively located on both sides of the stirring rod 52.

[0026] The added silt may be mixed with impurities such as floating objects, but they will adhere to the silt and will not float on the liquid surface (it should be explained that when extracting silt, water and silt are usually extracted together, so the silt contains a large amount of water). Then the motor 3 is started, and under the action of the linkage gear 6, the two sets of stirring rods 52 are driven to rotate relative to each other, so that the silt and floating objects are stirred, and the floating objects are separated from the silt (the separated floating objects will float on the liquid surface under the action of buoyancy). At the same time, the clumped silt can be broken up to facilitate the subsequent separation of impurities such as stones in the silt. Among them, during the operation of the stirring rod 52, some longer floating objects may be entangled on the stirring rod 52, affecting the stirring effect of the silt and being not conducive to the separation of the floating objects. During the operation, when gas is introduced into the air storage ring 53, the gas will be sprayed to both sides of the stirring rod 52 through the spray hole 54, so as to facilitate the separation of the floating objects from the stirring rod 52 and improve the separation effect of the floating objects.

[0027] Step 3: The detached floating objects will float on the liquid surface, and the processing equipment can salvage and collect the floating objects; Reference Figure 3 , Figure 5 and Figure 6 The salvaging mechanism includes a transverse shaft 12 and a reciprocating screw 15 rotatably connected to the inner wall of the processing box 1, and the transverse shaft 12 and the reciprocating screw 15 are respectively fixedly connected with a first connecting gear 14 and a second connecting gear 16, and a slider 17 is provided on the reciprocating screw 15. A fixed plate 18 is fixedly connected to the bottom of the slider 17, and a movable screen plate 19 is slidably connected inside the fixed plate 18, wherein the first connecting gear 14 and the second connecting gear 16 are meshed with each other, and a height monitoring mechanism and a collecting mechanism are provided inside the processing box 1, and a driving wheel 7 is fixedly connected to one end of the rotating shaft 4 close to the motor 3, and a connecting shaft 8 is rotatably connected to the side of the processing box 1 close to the driving wheel 7, and a driven wheel 9 is fixedly connected to the end of the connecting shaft 8, and a belt 10 is sleeved between the driving wheel 7 and the driven wheel 9. The connecting shaft 8 A driving bevel gear 11 is fixedly connected to the end away from the driven wheel 9, and a driven bevel gear 13 meshing with the driving bevel gear 11 is fixedly connected to the transverse axis 12. The collecting mechanism includes a first collecting box 33 fixedly connected to the outer wall of the processing box 1, a sewage outlet 28 is provided on the side of the processing box 1 close to the first collecting box 33, and a slide groove 29 is provided on the side of the side wall of the processing box 1 close to the sewage outlet 28. A supporting cylinder 30 is slidably connected inside the slide groove 29, and a supporting plate 32 slidably connected to the slide groove 29 is fixedly connected to the top of the supporting cylinder 30, and a first spring 31 sleeved on the supporting cylinder 30 is fixedly connected between the supporting plate 32 and the bottom of the slide groove 29, wherein the supporting cylinder 30 is connected to the chamber between the float 24 and the piston plate 22, and the nozzle 27 is close to the sewage outlet 28.

[0028] When the silt is stirred, the horizontal shaft 12 is driven to rotate, and under the action of the first connecting gear 14 and the second connecting gear 16, the reciprocating screw 15 is driven to rotate, thereby driving the fixed plate 18 and the movable screen plate 19 to move back and forth, and the floating objects on the liquid surface are salvaged, and finally collected in the first collecting box 33 through the sewage outlet 28, wherein the height of the movable screen plate 19 can be adjusted according to the height of the liquid level, on the one hand, it can avoid failing to salvage the floating objects, and on the other hand, it can reduce the contact between the movable screen plate 19 and the bottom silt, thereby ensuring the salvage effect of the floating objects, and at the same time, the height of the support plate 32 is adjusted according to the height of the liquid level to avoid blocking the flow of floating objects and the loss of silt. Step 4: Adjust the size of the discharge position of floating objects according to the height of the liquid level, and adjust the discharge speed of sediment to control the height of the liquid level; Reference Figure 3 and Figure 5The height monitoring mechanism includes a slope 20 fixedly connected to the processing box 1, the slope 20 is located below the reciprocating screw 15, and a sealing box 21 is fixedly connected to the side of the slope 20 close to the movable screen plate 19, and a piston plate 22 is slidably connected inside the sealing box 21, and a support rod 23 slidably connected to the sealing box 21 is fixedly connected to the side of the piston plate 22 away from the slope 20, and a float 24 is fixedly connected to the top of the support rod 23, and a mounting groove 34 is opened inside the slope 20, and an adjusting plate 35 is slidably connected inside the mounting groove 34, wherein the piston plate 22 divides the sealing box 21 into two chambers, wherein the chamber away from the side of the movable screen plate 19 is connected to the fixed plate 18 and the mounting groove 34, and a first compression cylinder 25 and two groups of second compression cylinders 26 are fixedly connected to the side of the inner wall of the processing box 1 close to the fixed plate 18, and a nozzle 27 is connected to one group of the second compression cylinders 26.

[0029] After the silt is added to the treatment box 1, the adjustment plate 35 is first in a closed state until the silt and water on the slope 20 reach a certain height, driving the float 24 to move upward to monitor the height of the liquid level on the slope 20. At the same time, the discharge amount is adjusted in time according to the amount of silt added to the liquid surface, so that the liquid level on the slope 20 is always in a stable height range to ensure the separation effect of floating objects and silt, and to facilitate the collection of floating objects. When the movable screen plate 19 moves to the beginning of the sewage outlet 28, the gas can be blown to the sewage outlet 28 by compressing the second compressed air cylinder 26 to speed up the collection efficiency of floating objects. At the same time, the first compressed air cylinder 25 and the second compressed air cylinder 26 can provide pressure for the air storage chamber 410.

[0030] Step 5: After the floating objects are processed, the stones in the sediment are collected, and the sediment is first settled under the processing equipment; Reference Figure 3 The filtering unit includes a plurality of vibration rods 36 fixedly connected to the inside of the processing box 1 and the bottom of the slope 20, and a filter plate 37 fitted with the processing box 1 is fixedly connected between the vibration rods 36 on both sides. A through hole 38 is opened on the side of the processing box 1 close to the filter plate 37, and a second collecting box 39 is fixedly connected to the side of the processing box 1 close to the through hole 38, wherein the filter plate 37 is arranged at an angle, and the bottom end of the filter plate 37 is close to the through hole 38.

[0031] The silt after the separation of floating objects will fall onto the filter plate 37, and the filter plate 37 will be driven to vibrate under the action of the vibration rod 36, thereby accelerating the separation efficiency of impurities such as stones and the flow speed of silt, and at the same time avoiding the blockage of the filter plate 37. It needs to be explained that the vibration rod 36 has a certain elasticity, which can make the filter plate 37 vibrate when the force on the filter plate 37 is different.

[0032] Step 6: When the sediment settles to a certain amount, the sediment is compressed and discharged to reduce the moisture in the discharged sediment to facilitate the subsequent dehydration of the sediment.

[0033] Reference Figure 3 and Figure 7 The dehydration unit includes a discharge port 40 opened at the bottom of the processing box 1, and a compression mechanism 41 and a material blocking mechanism 42 are arranged on the side of the processing box 1 close to the discharge port 40, wherein the compression mechanism 41 includes an air storage chamber 410 symmetrically opened on the side of the processing box 1 close to the discharge port 40, and a one-way valve 411 and a pressure relief valve 412 are connected to the side of the outer wall of the processing box 1 close to the air storage chamber 410, and a groove 413 is opened on the side of the processing box 1 close to the discharge port 40, and a compression plate 416 is slidably connected inside the groove 413, and multiple groups of connecting cylinders 415 are fixedly connected between the compression plate 416 and the groove 413, and a second spring 417 is sleeved on the connecting cylinder 415, and the groove 413 is connected to the air storage chamber 4 10 is connected with a pneumatic valve 414, the one-way valve 411 is connected with the first compression cylinder 25 and the second compression cylinder 26 through a pipeline, the pressure relief valve 412 is connected with the air storage ring 53 through a pipeline, the blocking mechanism 42 includes a transverse groove 420 which is symmetrically opened on the side of the processing box 1 close to the discharge port 40, the interior of the transverse groove 420 is slidably connected with a baffle 421, a discharge cylinder 422 is connected between the baffle 421 and the transverse groove 420, and the outside of the discharge cylinder 422 is sleeved with a third spring 423, wherein the baffle 421 is located below the compression plate 416, the discharge cylinder 422 is connected with the connecting cylinder 415 through a pipeline, and the outer wall of the processing box 1 is also connected with a drain outlet 43.

[0034] After the stones and other impurities are separated, the silt will fall to the bottom of the processing box 1 (discharge port 40). Initially, under the action of the baffle 421, the silt will not be discharged immediately, and the gas compressed by the first compression cylinder 25 and the second compression cylinder 26 will continuously enter the gas storage chamber 410 until the air pressure in the gas storage chamber 410 reaches the threshold value, and the excess gas will pass through the pressure relief valve 412 to the gas storage ring 53. The gas transportation during rotation can be achieved by installing an air slip ring on the mounting cylinder 51. This is a conventional method in the prior art, so it will not be elaborated. When the silt in the discharge port 40 reaches a certain amount (it needs to be explained that the more silt at the bottom of the processing box 1, the greater the force exerted on the compression plate 416, and the greater the compression of the connecting cylinder 415), the connecting cylinder 41 The air pressure provided by the air storage chamber 410 can open the pneumatic valve 414. At this time, the gas in the air storage chamber 410 quickly enters the groove 413, driving the compression plate 416 to compress the silt (during the compression process, part of the silt moves upward and the water flows upward), while reducing the volume of the silt between the compression plates 416. The water can also be recovered through the drain port 43. When the compression plate 416 moves, it will drive the connecting cylinder 415 to extend outward, and the gas in the discharge cylinder 422 will be sucked into the connecting cylinder 415, thereby driving the baffle 421 to be in an open state, and then the compressed silt is discharged through the discharge port 40. The water content of the discharged silt is relatively low, thereby improving the efficiency of subsequent dehydration of the silt, and at the same time can reduce the transportation cost of the silt, which is more economical and practical.
