Description

Technical Field

[0001] This utility model relates to the field of silt treatment technology, and in particular to a silt treatment device for river channel management in water conservancy and hydropower projects. Background Technology

[0002] River dredging is a necessary operation to ensure the normal functioning of waterways, but the treatment of sludge after dredging still faces many problems that hinder the development of the industry. With technological advancements, sludge can now be treated and used for agricultural soil improvement; consequently, a series of corresponding sludge treatment equipment have emerged. However, some problems still exist. In the preliminary filtration stage, most equipment lacks effective methods or is ineffective; larger debris entering the equipment can cause blockages, affecting processing efficiency and even damaging components. In the crushing stage, the crushing effect on dead branches and leaves in the sludge is poor, making it difficult for the sludge to reach ideal fertilizer standards. In the discharge stage, the viscous nature of the sludge easily leads to blockages. Utility Model Content

[0060] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0061] Reference Figure 1-18 A silt treatment device for river channel management in water conservancy and hydropower projects, comprising:

[0062] The bottom cylinder 1 is rotated by an external power source;

[0063] The crushing cylinder shell 2 is fixedly installed above the bottom cylinder 1 by the bracket 100;

[0064] The crushing blade assembly 3 is located inside the crushing cylinder shell 2 and is fixedly assembled with the central shaft 11 of the bottom cylinder 1;

[0065] And, located below the shredder assembly 3, a dividing screen 4 is installed inside the shredder housing 2;

[0066] The dividing screen 4 divides the overall internal space into two sections: the upper sludge crushing area and the lower discharge area.

[0067] like Figure 2 As shown; the bracket 100 with multiple legs provides basic support for the entire equipment; the bottom cylinder 1 is rotatably assembled on the bracket 100 near the lower end; the crushing cylinder shell 2 is open at the top and bottom and is located above the bottom cylinder 1; and the outer diameter of the crushing cylinder shell 2 matches the inner diameter of the bottom cylinder 1, and the lower end of the crushing cylinder shell 2 (designed to be slightly smaller to reduce friction) is inserted into the bottom cylinder 1.

[0068] In use, the sludge to be treated is fed into the crushing cylinder 2 from the top; the sludge is crushed by the crushing blade assembly 3; then, after passing through the appropriate sludge blocks, it falls into the bottom cylinder 1 through the dividing screen 4 and is discharged outward.

[0069] Preferably, the bottom cylinder 1 is connected to the power unit via a belt or gear to achieve rotation; the power unit can be a motor, engine, etc.

[0070] Correspondingly, at least two layers of support rings 12 are fixedly provided on the outer side of the bottom cylinder 1; rollers 101 are provided on the bracket 100 to cooperate with the support rings 12 and provide rotational support for the bottom cylinder 1.

[0071] Understandably, each support ring 12 should have at least 3 limiting points to ensure that no deviation occurs during rotation; as shown in the attached figure. Figure 5 As shown, five rollers 101 are provided for support and limiting.

[0072] In some embodiments, the lower end of the central shaft 11 is fixedly connected to the bottom cylinder 1, extends upward through the dividing screen 4 and is then fitted with the crushing blade assembly 3; the central shaft 11 of the bottom cylinder 1 directly drives the crushing blade assembly 3 to rotate.

[0073] It is understandable that the central shaft 11 is located at the center of the bottom cylinder 1 and is arranged vertically; during use, the crushing cylinder shell 2 is fixed; when the bottom cylinder 1 is rotating, the crushing blade assembly 3 is driven to rotate and crush the incoming sludge.

[0074] In some embodiments, the shredder assembly 3 includes: multiple horizontal blades 31, and vertical blades 32 that vertically connect the horizontal blades 31.

[0075] like Figure 12 As shown, the multi-layered blades ensure good treatment results; the added vertical blade 32 breaks up the silt from different directions; the combination of horizontal and vertical blades further ensures the treatment effect.

[0076] Furthermore, by adding the vertical blade 32, the strength of the crushing blade assembly 3 can be significantly improved, making it more reliable.

[0077] Furthermore, each layer of horizontal blades 31 has at least two blades of different lengths.

[0078] like Figure 12 As shown, each layer is equipped with three horizontal blades 31; by designing them in different lengths, different striking positions and striking forces are applied to the falling silt.

[0079] In some embodiments, an inclined baffle 5 for pressing down sludge is also provided above the dividing screen 4 to accelerate the falling of sludge.

[0080] Specifically, multiple inclined paddles 5 are fixedly assembled around the central shaft 11; their rear ends (in the working state) are inclined downwards, forming a sloping shape with the front end raised; such as Figure 12 As shown, in the working state (when rotating counterclockwise), the inclined surface of the inclined blade 5 presses down the silt.

[0081] It should be noted that the sludge is a viscous substance with a certain amount of moisture; it easily clumps and accumulates above the dividing screen 4; it can be quickly discharged downwards by the pressure and pushing action of the inclined deflector 5.

[0082] It should be noted that there is a gap between the lower end of the inclined blade 5 and the dividing screen 4 to avoid friction between the two.

[0083] In addition, after a period of use, this device can be reversed (stop feeding state); the sludge above the dividing screen 4 can be pushed upward by the inclined blade 5 to clean the dividing screen 4.

[0084] In some embodiments, the bottom cylinder 1 is provided with intermittent spiral blades 6; in the working state, the spiral blades 6 apply a downward conveying force to the sludge; at the same time, a discharge port 61 is provided on the side wall of the bottom cylinder 1 corresponding to the bottom end position of the spiral blades 6.

[0085] like Figures 10-15 As shown, as the bottom cylinder 1 rotates, the spiral blades 6 generate a downward conveying force, which is more conducive to the downward accumulation of sludge; moreover, the intermittent arrangement reduces blockages and other issues.

[0086] Understandably, some of the sludge falls onto the spiral blade 6, while some falls into the inner diameter space of the spiral blade 6, directly descending to the bottom of the bottom cylinder 1.

[0087] In this scheme, the sludge falling into the bottom cylinder 1 is thrown to the outer position under centrifugal force; in conjunction with the spiral blade 6, it is discharged outward from the discharge port 61, and there is basically no blockage.

[0088] Furthermore, the bottom of the bottom cylinder 1 is provided with fine drainage holes 62; some water can be discharged directly through the drainage holes 62 instead of through the discharge port 61.

[0089] It should be noted that the above solution achieves the discharge of treated sludge; however, inevitably, both sludge and water are easily thrown everywhere; therefore, some structures need to be designed at the bottom of the bottom cylinder 1 to solve this problem.

[0090] Preferably, a drainage structure 7 is fitted on the lower outer side of the bottom cylinder 1 to discharge water and solids separately.

[0091] Specifically, the drainage structure 7 includes: a lower cover 71 that cooperates with the lower end structure of the bottom cylinder 1; the lower center of the lower cover 71 extends downward to form a drainage shell 72 with a bottom inclined plate; a drainage port 73 is provided on the outer ring side of the drainage shell 72 corresponding to the lowest end; and a discharge pipe 74 with an opening space larger than the discharge port 61 is provided on the outer ring side of the lower cover 71.

[0092] It should be noted that, except for the area of ​​the discharge pipe 74, the lower cover 71 and the bottom cylinder 1 cooperate to block the discharge port 61; in the working state, the discharge port 61 intermittently overlaps with the discharge pipe 74 to discharge the sludge outward; correspondingly, the water passing through the drainage hole 62 enters the drainage shell 72 and is then led out from the drainage port 73.

[0093] It should be noted that the discharge of sludge is intermittent and at a certain speed; in order to avoid the high-speed spillage of sludge, the end of the discharge pipe 74 is equipped with a downward-folding structure or baffle to form a blocking effect; or, the end of the discharge pipe 74 is directly connected to a longer pipe to transport the material to the stockpile.

[0094] In some embodiments, a large-aperture primary screen 8 is also provided above the crushing cylinder shell 2 to pre-screen excessively large debris and reduce adverse effects on subsequent operations.

[0095] Furthermore, the primary screening screen 8 is provided with multiple screens via a rotating switching frame 102.

[0096] When one primary screen 8 needs cleaning, rotate the other primary screen 8 above the crushing cylinder shell 2.

[0097] Understandably, the rotating switching frame 102 is mounted on the support 100; through rotation, different primary screens 8 are switched for operation; after the primary screen 8 to be cleaned is moved to the outside, the debris is removed.

[0098] Furthermore, the outer ring of the primary screen 8 has a retaining edge 81 to prevent the screened debris from spilling out.

[0099] Furthermore, the baffle 81 is detachable; when moving to the outer discharge area, the baffle 81 can be removed, making operation more convenient and cleaning more thorough.

[0100] Preferably, multiple sets of clamping plates 82 are fixedly provided on the outer ring side of the primary screening screen 8 to clamp and fix the retaining edge 81.

[0101] When using this utility model, the equipment is moved to a suitable position, and the discharge pipe 74 and the drain outlet 73 are connected to the material storage area and the water storage area. After the equipment is placed stably, a primary screen 8 is switched to the top of the crushing cylinder shell 2 to prepare for operation. During the sludge treatment process, larger debris is screened out by the primary screen 8. Sludge of suitable size enters the crushing cylinder shell 2 and is processed by the crushing blade assembly 3. Afterward, it falls into the bottom cylinder 1 through the dividing screen 4 and is discharged outward.

[0102] In this invention, a crushing cylinder shell 2 is set up in conjunction with a bottom cylinder 1 to fully crush and process the sludge, preventing it from clogging during discharge. Multiple horizontal blades 31 and vertical blades 32 work together to crush the sludge from different directions, further ensuring the processing effect and improving the strength and reliability of the crushing blade assembly 3. An inclined blade 5 is set up to accelerate the sludge's fall. Centrifugal force combined with a spiral blade 6 ensures that the sludge discharge is virtually unobstructed. Multiple primary screens 8 are set up by rotating the switching frame 102 to avoid the influence of large debris. A baffle 81 is also set up to prevent the debris retained on the screen from spilling out, and cleaning is more convenient and thorough.
