Description

Technical Field

[0001] This utility model relates to the field of residual mud and slag treatment technology, and in particular to a device for treating residual mud and slag construction waste. Background Technology

[0002] Excess soil and slag refer to the waste soil, waste materials and excess soil generated during the construction, renovation, expansion and demolition of buildings, structures, pipelines, etc. The composition includes soil, sand, stone, clay, gravel, etc., and some contain construction waste such as concrete blocks and bricks.

[0003] By using waste soil and slag treatment equipment to separate mud and sand through washing, the large stones after separation can be crushed in a crushing line, and the separated sand can be used as fine aggregate, allowing the separated sand and gravel to be reused in the construction market. The remaining sludge after washing and settling is then dewatered by pressure filtration to form mud cakes, which can be directly used for roadbed subbase, improved soil backfill, or the preparation of sintered bricks, thus solving the problem of waste soil and slag treatment.

[0004] The residual mud and slag after the fine aggregate is recycled need to be settled and concentrated to reduce the moisture content before being filtered. When the residual mud and slag enter the thickening tank, they settle downwards again, causing high-concentration mud to accumulate at the bottom of the thickening tank, which can easily clog the discharge pipe and make it difficult to collect the high-concentration mud.

[0005] Therefore, it is necessary to provide a new device for treating construction waste such as sludge and rubble to solve the above problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a device for treating residual mud and construction waste that facilitates the rapid discharge of high-concentration mud.

[0007] To solve the above-mentioned technical problems, the present invention provides a waste sludge and construction waste treatment device comprising: a thickening tank, wherein an inlet pipe and an outlet pipe are respectively installed at both ends of the thickening tank, and a conveyor belt is rotatably connected to the bottom end of the thickening tank, and elastic scrapers are equidistantly installed on the surface of the conveyor belt; a collection tank is installed at the bottom end of the thickening tank, and a fixing plate is installed at the connection between the collection tank and the thickening tank; multiple sewage pipes are installed at the funnel-shaped end of the collection tank, and multiple first connecting pipes are installed at the arc-shaped end of the side wall of the collection tank; the first connecting pipes correspond one-to-one with the sewage pipes, and the centers of the corresponding first connecting pipes and the sewage pipes are located in the same plane; multiple second connecting pipes are installed obliquely on the side wall of the fixing plate, and the outlets of the arc-shaped second connecting pipes face the sewage pipes.

[0008] Preferably, multiple first baffles are installed at an angle on the top of the thickening tank, and multiple second baffles are installed vertically inside the thickening tank. The distance between adjacent first baffles and the distance between adjacent second baffles gradually decrease along the feed pipe toward the outlet pipe.

[0009] Preferably, the scraper is arranged in a "V" shape on the surface of the conveyor belt, and the shortest distance between the scraper and the second baffle is 1 to 2 centimeters.

[0010] Preferably, the thickening tank has multiple supporting rollers rotatably connected inside, and the supporting rollers are slidably connected to the conveyor belt; a drive motor is installed at one end of the collection tank, and the drive motor is connected to one of the supporting rollers.

[0011] Preferably, the width of the conveyor belt gradually increases along the direction from the feed pipe to the outlet pipe, and the end with the largest width of the conveyor belt is located inside the collection pool.

[0012] Preferably, the top surface and side walls of the fixing plate are inclined, and an elastic connecting rod is installed on the side wall of the fixing plate at an inclined angle, and the elastic connecting rod is slidably connected to the scraper.

[0013] Preferably, valves are installed on the side walls of the first connecting pipe, the second connecting pipe, and the sewage pipe.

[0014] Compared with related technologies, the waste soil and slag treatment device provided by this utility model has the following beneficial effects: This utility model provides a device for treating construction waste such as sludge and slag. When the sludge enters the thickening tank, the solid particles inside the sludge settle downwards. The conveyor belt and scraper inside the thickening tank rotate continuously clockwise. The rotation of the scraper pushes the settled sludge between the thickening tank and the conveyor belt, initially separating the sediment from the water inside the thickening tank, facilitating sediment collection. Furthermore, as the scraper rotates, it continuously pushes the sediment into the collection tank, preventing sediment accumulation inside the thickening tank. At this point, the sludge concentration entering the collection tank is high. A blower is connected to the first and second connecting pipes, and air is rapidly ejected through the first and second connecting pipes. The first connecting pipe corresponds to the sewage pipe, and the corresponding second connecting pipe... A connecting pipe and the center of the drain pipe are located in the same plane. Air rapidly ejected from the first connecting pipe rushes into the interior of the drain pipe, pushing the sediment in the collection tank to be quickly discharged through the drain pipe. The outlet of the inclined second connecting pipe faces the drain pipe. Airflows ejected from multiple second connecting pipes rush into the interior of the drain pipe from different directions, pushing the surrounding sediment into the interior of the drain pipe quickly. The airflow continuously enters the interior of the drain pipe, preventing blockage and accelerating the cleaning efficiency of the sediment in the collection tank. During the process of pushing out the sediment in the collection tank, air continuously enters the interior of the collection tank, occupying the space inside the collection tank and reducing the water content inside the collection tank, thereby reducing the water content inside the sediment and facilitating the further processing of the sediment.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1 to 3 , Figure 1 A schematic diagram of a preferred embodiment of the construction waste treatment device for residual mud and slag provided by this utility model; Figure 2 for Figure 1 The diagram shows an enlarged view of the structure at point A. Figure 3 for Figure 2 The image shows a top view of the internal structure of the collection pool. A construction waste treatment device for sludge and slag includes a thickening tank 3. An inlet pipe 1 and an outlet pipe 2 are respectively installed at both ends of the thickening tank 3. A conveyor belt 4 is rotatably connected to the bottom of the thickening tank 3, and elastic scrapers 42 are equidistantly installed on the surface of the conveyor belt 4. When sludge enters the thickening tank 3, the solid particles inside the sludge settle downwards. The conveyor belt 4 and the scrapers 42 inside the thickening tank 3 rotate continuously clockwise. The rotating scrapers 42 push the settled sludge between the thickening tank 3 and the conveyor belt 4, initially separating the sediment from the water inside the thickening tank 3, facilitating sediment collection. The scrapers 42 are arranged in a "V" shape on the surface of the conveyor belt 4 to facilitate sediment retention inside the scrapers 42. The minimum distance between the scrapers 42 and the second baffle 32 is 3 to 5 centimeters. To minimize the distance between the scrapers 42 and the second baffle 32, the sludge water moves up and down along the first baffle 31 and the second baffle 32.

[0019] A collection tank 5 is installed at the bottom of the thickening tank 3. A fixing plate 6 is installed at the connection between the collection tank 5 and the thickening tank 3. Multiple sewage pipes 9 are installed at the funnel-shaped end of the collection tank 5, and multiple first connecting pipes 7 are installed at the arc-shaped end of the side wall of the collection tank 5. The first connecting pipes 7 and the sewage pipes 9 correspond one-to-one, and the centers of the corresponding first connecting pipes 7 and the sewage pipes 9 are located in the same plane. Multiple second connecting pipes 8 are installed at an angle on the side wall of the fixing plate 6, and the outlets of the arc-shaped second connecting pipes 8 face the sewage pipes 9. The first connecting pipe 7 and the second connecting pipe 8 are internally connected to a blower. Air is rapidly ejected through the first connecting pipe 7 and the second connecting pipe 8. The first connecting pipe 7 corresponds to the sewage pipe 9, and the centers of the corresponding first connecting pipe 7 and the sewage pipe 9 are located in the same plane. The air rapidly ejected from the first connecting pipe 7 rushes into the interior of the sewage pipe 9, pushing the sediment inside the collection tank 5 to be quickly discharged through the sewage pipe 9. The outlet of the inclined second connecting pipe 8 faces the sewage pipe 9. The airflow ejected from multiple second connecting pipes 8 rushes into the interior of the sewage pipe 9 from different directions, pushing the surrounding sediment into the interior of the sewage pipe 9 quickly. The airflow continuously enters the interior of the sewage pipe 9, preventing the sewage pipe 9 from becoming blocked and accelerating the cleaning efficiency of the sediment inside the collection tank 5.

[0020] Multiple first baffles 31 are installed at an angle at the top of the thickening tank 3, and multiple second baffles 32 are installed vertically inside the thickening tank 3. After the slurry enters the thickening tank 3, it moves along the first baffles 31 and the second baffles 32, causing the slurry to move up and down continuously, thus accelerating the settling of solid particles. The distance between adjacent first baffles 31 and the distance between adjacent second baffles 32 gradually decreases along the feed pipe 1 towards the outlet pipe 2. The closer to the feed pipe 1, the more solid particles the slurry contains, and the greater the space for slurry movement, which is conducive to the settling of solid particles. Furthermore, by reasonably setting the distance between the baffles, the length of the thickening tank 1 can be reduced, saving costs and thickening space.

[0021] Multiple support rollers 41 are rotatably connected inside the thickening tank 3, and the support rollers 41 are slidably connected to the conveyor belt 4. A drive motor 12 is installed at one end of the collection tank 5, and the drive motor 12 is connected to one of the support rollers 41. In order to facilitate the operation of the drive motor 12 to drive the support roller 41 to rotate, thereby driving the conveyor belt 4 to rotate, the sediment inside the thickening tank 3 is continuously pushed into the interior of the collection tank 5.

[0022] The width of the conveyor belt 4 gradually increases along the feed pipe 1 toward the outlet pipe 2, with the widest end of the conveyor belt 4 located inside the collection tank 5. To make the distance between the scraper 42 and the second baffle 32 gradually increase along the outlet pipe 2 toward the feed pipe 1, the scraper 42 can easily carry away more and more sediment below the second baffle 32. The distance between the scraper 42 and the bottom surface of the thickener 3 gradually decreases along the outlet pipe 2 toward the feed pipe 1, so that the scraper 42 can push the sediment at the bottom of the thickener 3 into the collection tank 5.

[0023] The top surface and side walls of the fixing plate 6 are inclined. An elastic connecting rod 11 is installed on the inclined side wall of the fixing plate 6, and the elastic connecting rod 11 is slidably connected to the scraper 42. When the scraper 42 rotates into the collection tank 5, the sediment inside the scraper 42 is pushed into the collection tank 5. As the scraper 42 rotates and contacts the connecting rod 11, the connecting rod 11 squeezes the elastic scraper 42, causing the scraper 42 to bend downwards, facilitating the falling of any remaining sediment inside the scraper 42 into the collection tank 5. As the scraper 42 deforms and separates from the connecting rod 11, the scraper 42 moves upwards again. The scraper 42 rotates upwards and contacts multiple connecting rods 11, causing the scraper 42 to deform multiple times, facilitating the cleaning of any remaining sediment inside the scraper 42.

[0024] Valves 10 are installed on the side walls of the first connecting pipe 7, the second connecting pipe 8, and the sewage pipe 9 to facilitate the closing and opening of the first connecting pipe 7, the second connecting pipe 8, and the sewage pipe 9.

[0025] The working principle of this utility model is as follows: The drive motor 12 is connected to an external power source. The operation of the drive motor 12 drives the support roller 41 to rotate, thereby driving the conveyor belt 4 to rotate slowly. It takes approximately 3 minutes for the conveyor belt 4 to complete one revolution. After the mud pump delivers mud and flocculant into the thickening tank 3 through the feed pipe 1, the mud moves along the first baffle 31 and the second baffle 32, causing the mud to move up and down continuously, accelerating the settling of solid particles. The conveyor belt 4 and the scraper 42 rotate continuously clockwise. The rotation of the scraper 42 pushes the settled mud and sand into the space between the thickening tank 3 and the conveyor belt 4, initially separating the sediment from the water inside the thickening tank 3, facilitating sediment collection. The rotation of the scraper 42 below the conveyor belt 4 pushes the sediment at the bottom of the thickening tank 3 into the collection tank 5. As the scraper 42 inside the collection tank 5 rotates and contacts the connecting rod 11, the connecting rod 11 squeezes the elastic scraper 42, causing the scraper 42 to bend and deform downwards, making it easier for residual sediment inside the scraper 42 to fall into the collection tank 5; as the scraper 42 deforms and separates from the connecting rod 11, the scraper 42 moves upwards again; the scraper 42 rotates upwards and contacts multiple connecting rods 11, causing the scraper 42 to deform multiple times, making it easier to clean the residual sediment inside the scraper 42. When it is necessary to clean the sediment inside the collection tank 5, a blower is connected inside the first connecting pipe 7 and the second connecting pipe 8, and the drain pipe 9 is opened; air is quickly ejected through the first connecting pipe 7 and the second connecting pipe 8. The first connecting pipe 7 corresponds to the drain pipe 9, and the centers of the corresponding first connecting pipe 7 and the drain pipe 9 are located in the same plane. The air quickly ejected from the first connecting pipe 7 rushes into the interior of the drain pipe 9, pushing the sediment inside the collection tank 5 to be quickly discharged through the drain pipe 9. The outlet of the inclined second connecting pipe 8 faces the drain pipe 9. The airflow ejected from multiple second connecting pipes 8 rushes into the interior of the drain pipe 9 from different directions, pushing the surrounding sediment into the interior of the drain pipe 9 quickly. The airflow continuously enters the interior of the drain pipe 9, preventing the drain pipe 9 from becoming blocked and accelerating the cleaning efficiency of the sediment inside the collection tank 5.
