Description

Technical Field

[0001] This utility model belongs to the field of construction waste recycling technology, specifically relating to a construction waste recycling device applied to soil improvement. Background Technology

[0002] One way to utilize construction waste is through recycling and reuse. Many construction wastes, such as concrete blocks, bricks, and wood, can be crushed, screened, and washed to serve as recycled aggregates for foundations in new construction projects, road paving, or for making new concrete products. This approach not only reduces the extraction of natural resources but also lowers construction costs.

[0003] Another approach is energy recovery. Combustible materials in construction waste, such as plastics and wood, can be converted into heat energy through incineration for power generation or heating. This method not only solves the land occupation problem caused by waste but also provides clean energy for the city, achieving the dual benefits of waste utilization.

[0004] There is also the application of biodegradation technology. Organic components in construction waste, such as soil and plant residues, can be decomposed through biotechnology and transformed into fertilizers or soil conditioners for urban greening or agricultural cultivation. This not only restores the ecological balance but also enhances the land's utilization value.

[0005] Construction sludge is usually generated during the foundation construction stage of building projects, such as foundation excavation, river dredging, and basement construction. These operations produce a large amount of muddy material containing a lot of water. This construction sludge is difficult to use directly, and random dumping will occupy land and pollute the environment.

[0006] Traditional methods for treating construction sludge often involve dehydration and solidification before subsequent disposal such as landfilling and brick making to achieve reasonable treatment and resource reuse. However, due to the large and complex number of nitrogen, phosphorus, potassium, active microorganisms, and fungi in construction sludge, existing processes make it difficult to directly apply the treated sludge to soil improvement and crop planting. The complex composition of the sludge means that without separating solid impurities from the waste liquid and then performing composting and fermentation, it cannot be used for soil improvement, thus hindering the recycling and reuse of construction waste. Utility Model Content

[0007] The purpose of this invention is to provide a construction waste recycling device for soil improvement, which can settle particulate matter and suspended matter in sludge. After the settled impurities are fermented with liquid, solid fertilizer and liquid fertilizer are formed to increase soil fertility.

[0008] The specific technical solution adopted by this utility model is as follows:

Detailed Implementation

[0032] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0033] like Figures 1-7 As shown, a construction waste recycling device for soil improvement includes multiple separation boxes 1, with sewage pipes 2 fixedly connected between the separation boxes 1, multiple first valves 3 installed on the side wall of the sewage pipes 2, brackets 4 fixedly connected to the bottom surface of each separation box 1, and a communication control component provided in the inner cavity of the separation box 1 near the bottom surface.

[0034] The first valve 3 is used to control the connection between the sewage pipe 2 and the separation box 1. In this scheme, two separation boxes 1 are preferred. When the construction sludge is discharged into the left separation box 1, the first valve 3 above the right separation box 1 is closed. Conversely, the construction sludge can be continuously treated.

[0035] Multiple separation tanks 1 have a water purification pipe 16 fixedly connected to the upper side of the communication control component, and multiple separation tanks 1 have a sludge discharge pipe 17 fixedly connected to the lower side of the communication control component. Multiple second valves 30 are installed on the side walls of the water purification pipe 16 and the sludge discharge pipe 17.

[0036] Specifically, multiple branch pipes are connected to the water purification pipe 16 and the sludge discharge pipe 17. The branch pipes are connected to multiple separation boxes 1 respectively, and the second valve 30 is installed at the branch pipe position to control whether the separation box 1 is in the discharge state.

[0037] A rotating shaft 19 is rotatably connected to the top surface of the inner cavity of the separation box 1. An agitator 20 is fixedly connected to the side wall of the rotating shaft 19. A motor 18 is fixedly installed on the top surface of the separation box 1, and the output shaft of the motor 18 is fixedly connected to the rotating shaft 19. By agitating the sludge, flocculants or coagulants can be added automatically, and the uniformity of contact between the particles in the sludge and the agent can be accelerated.

[0038] A reagent tank 21 is fixedly connected to the top surface of the separation tank 1. The reagent tank 21 is divided into at least two chambers. The reagent tank 21 can store a variety of reagents. The reagents are preferably those used in sewage treatment, such as flocculants or coagulants. A dispensing pipe 22 is fixedly connected to the bottom surface of the reagent tank 21. The dispensing pipe 22 extends into the interior of the separation tank 1. A material control component is provided on the side wall of the rotating shaft 19.

[0039] like Figures 3-6 As shown, the communication control component includes a fixed plate 5 fixedly connected to the inner wall of the separation box 1. The top surface of the fixed plate 5 has several first through slots 6. An inclined plate 7 is fixedly connected to the right side of the first through slot 6 on the top surface of the fixed plate 5. A guide plate 8 is fixedly connected to the side wall of the inclined plate 7 and the left side of the first through slot 6. A baffle 9 is provided in the inner cavity of the separation box 1 below the fixed plate 5. The top surface of the baffle 9 has several second through slots 10. The first through slots 6 and the second through slots 10 are staggered. An electric push rod 11 is installed on the side wall of the separation box 1. The output end of the electric push rod 11 is fixedly connected to the baffle 9. A sealing component is provided on the bottom surface of the fixed plate 5.

[0040] Specifically, both the inclined plate 7 and the guide plate 8 are inclined. During the sedimentation process, particles or flocculents can slide into the bottom of the separation chamber 1 using the inclined surfaces of the inclined plate 7 and the guide plate 8, thus preventing particles and flocculents from remaining in the liquid. After the solids have settled, the electric push rod 11 can be controlled to drive the baffle 9 to block the fixed plate 5, so that the first channel 6 and the second channel 10 are in an interleaved state, dividing the separation chamber 1 into two chambers, which facilitates the separate discharge of solids and liquids.

[0041] To further improve the sealing between the fixing plate 5 and the baffle 9, such as Figure 8 As shown, the sealing assembly includes several annular grooves 12 formed on the bottom surface of the fixed plate 5. The annular grooves 12 are rectangular and are located outside the first through groove 6. Several first springs 13 are fixedly connected to the top surface of each annular groove 12, and sealing rings 14 are fixedly connected to the bottom surface of each first spring 13. Magnetic sheets 15 are fixedly connected to the bottom surface of the sealing ring 14 and the top surface of the baffle 9, respectively, and the magnetic sheets 15 on both sides are magnetically attracted to each other.

[0042] The gap between the fixing plate 5 and the baffle 9 can be further reduced by the sealing component, and the attraction of the magnetic sheets 15 on both sides is greater than the elastic force of the first spring 13. Therefore, when the magnetic sheets 15 on both sides attract each other, the sealing ring 14 is pulled down and made to fit around the second through groove 10 to achieve the sealing effect. This principle is similar to that of a magnetic door lock.

[0043] like Figure 2 and Figure 7As shown, the material control assembly includes a cam 23 fixedly connected to the side wall of the rotating shaft 19, a rectangular groove is provided on the side wall of the medicine dispensing tube 22, a movable plate 24 is movably connected in the rectangular groove, a round hole 25 is provided on the top surface of the movable plate 24, the round hole 25 is adapted to the medicine dispensing tube 22, and an elastic element is provided on the end face of the movable plate 24.

[0044] Specifically, the swing of cam 23 can drive the movable plate 24 to extend and retract. When the round hole 25 is connected to the drug delivery pipe 22, the flocculant or coagulant aid in the drug tank 21 falls and mixes with the sludge, achieving the purpose of simultaneous addition and mixing. When the dosage of the drug is within the appropriate range, the motor 18 stops, and the drug addition stops. After that, it is left to stand for a certain period of time to allow the solids to settle.

[0045] like Figure 7 As shown, a movable wheel 29 is rotatably connected to the end face of the movable plate 24, and the movable wheel 29 abuts against the side wall of the cam 23.

[0046] The elastic element includes a limiting rod 26 fixedly connected to the side wall of the movable plate 24. The other end of the limiting rod 26 passes through the separation box 1 and is movably connected to it. A second spring 27 is sleeved on the side wall of the limiting rod 26.

[0047] The movable wheel 29 can reduce the contact friction between the movable plate 24 and the cam 23, thereby improving the transmission efficiency of the cam 23. In addition, with the action of the second spring 27, the movable plate 24 can always be in a state of resistance with the cam 23, thus ensuring the accuracy of drug delivery.

[0048] like Figure 2 As shown, a protective cover 28 is fixedly connected to the top surface of the inner cavity of the separation box 1, and the material control component is located inside the protective cover 28. Since sludge and sewage will splash during stirring inside the separation box 1, the protective cover 28 can play a protective role in order to avoid affecting the operation of the cam 23 and extend the service life of the transmission structure.

[0049] The working principle of this utility model is as follows: First, the construction sludge is discharged into one of the separation boxes 1 through the sewage pipe 2. At this time, the first channel 6 and the second channel 10 are in a connected state. The motor 18 is started, and the output shaft of the motor 18 drives the stirring blade 20 to rotate through the rotating shaft 19. The stirring blade 20 stirs and mixes the construction sludge.

[0050] The rotating shaft 19 simultaneously drives the cam 23 to rotate, and the cam 23 pushes the movable plate 24 to reciprocate, so that the round hole 25 on the movable plate 24 is intermittently connected to the drug delivery pipe 22. When the round hole 25 is connected to the drug delivery pipe 22, the flocculant or coagulant aid in the drug tank 21 falls and mixes with the sludge. When the amount of flocculant added reaches the set range, the motor 18 stops running, and the movable plate 24 blocks the drug delivery pipe 22.

[0051] During the settling process, the sludge particles and flocculents begin to settle and settle at the bottom of the separation box 1 through the first channel 6 and the second channel 10. When the sedimentation time is set, the electric push rod 11 is activated to move the baffle 9, so that the second channel 10 on the baffle 9 intersects with the first channel 6, blocking the first channel 6 and dividing the separation box 1 into two chambers.

[0052] At the same time, after the baffle 9 moves, the magnetic sheets 15 on both sides attract each other, and the first spring 13 is stretched. The sealing ring 14 is used to further seal the area. Then the precipitated sludge or flocculent material is discharged through the sludge discharge pipe 17, and the upper liquid is discharged through the water purification pipe 16, achieving the effect of solid-liquid separation. After fermentation, the discharged solids and liquids can be used for soil improvement, fertilization and irrigation.

[0053] During the sludge treatment process, by controlling the first valve 3, the construction sludge can be discharged into the separation box 1 on the other side to achieve continuous treatment, thereby improving the reuse of construction waste and maximizing the rational reuse of waste resources.

[0054] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
