Description

Technical Field

[0001] This utility model relates to the field of sludge solidification, and more specifically, to a device for solidifying river and lake sludge. Background Technology

[0002] River silt refers to the mixture of mud and water that accumulates inside a river. River silt solidification is the solidification and drying process of the mixture of mud and water accumulated inside a river. The silt solidification device is designed to quickly and thoroughly mix the solidifying agent with the silt.

[0003] Current sludge solidification equipment injects a solidifying agent into the sludge while continuously agitating it. The sludge is in motion within the equipment, resulting in uneven distribution of the solidifying agent within the sludge. Furthermore, the solidifying agent only remains on the surface of the sludge, and the sludge and solidifying agent cannot fully integrate. In addition, the sludge contains a large amount of solid particulate impurities, requiring separate filtration, which is inefficient. Utility Model Content

[0016] 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; It should be noted that: all electrical components in this case and their compatible power supplies should be connected by wires by those skilled in the art, and the first motor, second motor and third motor should be connected to the equipment power supply. In addition, appropriate controllers should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection between each electrical component should be completed in the order of operation. The detailed connection method is well known in the art. The following mainly introduces the working principle and process, and will not explain the electrical control.

[0017] The model number of the first motor, the second motor and the third motor can be (ZD2-152). Please see Figures 1-4 In this utility model, a river and lake silt solidification device includes a mixing drum 1 and a filter drum 2. The filter drum 2 is horizontally rotatably disposed on the top of the mixing drum 1. The mixing drum 1 is provided with a solidifying agent injection component 3. The mixing drum 1 is equipped with a flow guiding inner cylinder 4. The flow guiding inner cylinder 4 is equipped with a flow guiding mixing component 5. A drive unit 6 for driving the filter cylinder 2 to rotate is installed on the top of the stirring cylinder 1; The filter cylinder 2 has a pusher blade 7 arranged in an inner spiral inside. The filter cylinder 2 has a uniformly distributed mud discharge hole 8 on its upper part. The filter cylinder 2 is covered with a guide cover 9 on its outer side. The bottom opening of the guide cover 9 is connected to the mixing cylinder 1. The curing agent injection component 3 includes a first motor 31, a rotating cylinder 32, and a uniformly distributed material distribution head 33. The first motor 31 is fixedly installed on the outside of the mixing cylinder 1. The output end of the first motor 31 is fixedly connected to the end of the rotating cylinder 32 through a coupling. The other end of the rotating cylinder 32 is rotatably connected to the external curing agent pipeline. A material distribution hole 34 is opened on the upper part of the rotating cylinder 32 to communicate with the material distribution head 33. In this invention, the drive unit 6 rotates the filter cylinder 2, and sludge is injected from the right side. After entering the filter cylinder 2, the sludge is fed into the middle section of the filter cylinder 2 as it rotates. Under the action of centrifugal force, it passes through the sludge discharge hole 8 and is discharged into the interior of the guide shroud 9. Then, it falls down along the guide shroud 9 into the interior of the mixing cylinder 1. Large solid impurities inside the sludge are discharged to the left by the pusher blades 7 during rotation, thus achieving filtration. At the same time, the first motor 31 is started to drive the rotating cylinder 32 to rotate, and high-pressure curing agent liquid is injected through the outer curing agent pipe. Then, as it rotates, the high-pressure curing agent liquid is evenly sprayed out through the uniform distribution hole 34 on the uniform distribution head 33, mixing with the falling sludge. With the rotation of the cylinder 32, the uniformity of the mixing of the curing agent and the sludge is improved, and the mixed sludge falls into the interior of the guide inner cylinder 4. Then, the second motor 31 is started simultaneously. The second motor 51 drives the hinge 52 to rotate, pushing the mixed sludge downwards. During the downward pushing process, the sludge is continuously in contact with the inclined rod assembly 53 and is agitated, achieving mixing. This mixing is also achieved during the conveying process. Finally, the evenly mixed sludge is discharged, and the solidifying agent is ready to take effect. This device achieves the advantages of more uniform mixing of solidifying agent and sludge, efficient filtration of internal solid particles, and simultaneous conveying and mixing, thus improving efficiency. It solves the problems of existing technologies where solidifying agent is injected into the sludge while it is continuously agitated, resulting in uneven solidifying agent distribution within the sludge due to the sludge's movement within the equipment. The solidifying agent only remains on the surface of the sludge, and the sludge and solidifying agent cannot fully integrate. Furthermore, the sludge contains a large amount of solid particle impurities, requiring separate filtration, which is inefficient.

[0018] Please see Figure 1 The flow guiding and stirring component 5 includes a second motor 51, a hinge 52, and a slant bar assembly 53. The second motor 51 is fixedly installed at the bottom of the stirring drum 1. The output end of the second motor 51 is fixedly connected to the hinge 52 through a coupling. The top end of the hinge 52 passes through and is rotatably connected to the inside of the flow guiding inner cylinder 4. The slant bar assembly 53 is evenly fixed to the inside of the flow guiding inner cylinder 4 and is staggered with the blades of the hinge 52.

[0019] In this invention, the mixing sludge is conveyed by starting the second motor 51 to drive the hinge 52. At the same time, the sludge is agitated by colliding with the inclined rod group 53 while flowing, thus achieving the advantage of conveying and stirring at the same time, improving efficiency.

[0020] Please see Figure 1 The drive unit 6 includes a third motor 61, a gear 62, and a gear ring 63. The third motor 61 is fixedly installed on the top of the mixing drum 1. The output end of the third motor 61 is fixedly connected to the gear 62 through a coupling. The inner side of the gear ring 63 is sleeved and fixed to the outer side of the mixing drum 1, and the outer side of the gear ring 63 meshes with the gear 62.

[0021] In this invention, the third motor 61 is started to drive the gear 62 to rotate, which in turn drives the gear ring 63 to rotate, thereby driving the filter cylinder 2 to rotate, so that it separates sludge and large solid particles during the rotation process.

[0022] Please see Figure 2 and Figure 4 The material leveling head 33 is hollow inside, and the material leveling head 33 has evenly distributed side holes 331.

[0023] In this invention, the hollow interior of the uniform material head 33, combined with the side holes 331, allows the curing agent to be sprayed more evenly in multiple directions, achieving more efficient and uniform contact and mixing with the falling sludge.

[0024] Please see Figure 1 The top of the mixing drum 1 is fixedly equipped with a feed hopper 10, and the left port of the feed hopper 10 is rotatably engaged with the port of the filter drum 2.

[0025] In this invention, the hopper 10 facilitates the feeding of sludge and smoothly guides the sludge into the interior of the filter cylinder 2.

[0026] Please see Figure 1 The filter cylinder 2 is open at the end away from the feed hopper 10 for material discharge, and the bottom of the guide inner cylinder 4 is equipped with an inclined discharge pipe 41.

[0027] In this invention, the discharge pipe 41, in conjunction with the hinge 52, pushes the sludge to ensure smooth discharge. Furthermore, the end of the filter cylinder 2 furthest from the feed hopper 10 directly discharges large solid particles, making the device operate more smoothly.

[0028] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
