Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment technology, and in particular to a water recycling flotation system. Background Technology

[0002] Due to imperfect sorting processes for construction and decoration waste, construction waste often contains large amounts of lightweight materials such as wood, fabric, plastic, and aerated concrete blocks. The presence of these lightweight materials leads to a decline in the physical properties of recycled aggregates, resulting in poor performance in terms of strength, durability, and stability.

[0003] Therefore, the resulting brick-concrete composite aggregates containing lightweight materials can often only be used in low-value-added fields such as low-grade bricks and road subbases, severely impacting the industry's profitability and development potential. Furthermore, the inefficiency and inadequacy of construction waste resource utilization leads to significant resource waste and environmental pollution. Lightweight materials that are not effectively sorted and utilized may be landfilled or incinerated, causing land occupation and air pollution, further hindering the healthy development of the construction waste resource utilization industry.

[0004] However, the flotation device for construction waste aggregates in the relevant technology requires a continuous flow of clean water during operation, which consumes a huge amount of water resources, does not meet the requirements of environmental protection, and is not conducive to the control of production costs.

[0021] Figure 1 is a schematic view of the water recycling floating system of the utility model embodiment.

[0022] REFERENCE NUMERALS:

[0023] 1-floating bin, 101-water inlet, 102-water outlet, 2-first transfer device, 3-second transfer device, 4-filtering device, 5-feeding hopper, 6-pressurizing pump. DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The water recycling flotation system of this utility model is described below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, the water recycling flotation system of this utility model embodiment includes: flotation chamber 1, transfer component and filtration device 4.

[0027] The flotation chamber 1 has an inlet 101 and an outlet 102 to enable water injection and pumping within the flotation chamber 1. The transfer assembly includes a first transfer device 2 and a second transfer device 3 distributed at intervals along the vertical direction, with the first transfer device 2 located above the second transfer device 3.

[0028] The input ends of the first transfer device 2 and the second transfer device 3 are both located inside the flotation chamber 1. The input end of the first transfer device 2 is close to the water surface of the flotation chamber 1 and is used to transport light materials in the flotation chamber 1. The input end of the second transfer device 3 is close to the bottom of the flotation chamber 1 and is used to transport heavy materials (such as bricks and concrete) in the flotation chamber 1, so as to achieve the function of separating materials of different densities.

[0029] The inlet of the filter device 4 is connected to the outlet 102 of the flotation chamber 1 via a pipeline, and the outlet of the filter device 4 is connected to the inlet 101 of the flotation chamber 1 via a pipeline. This allows water in the flotation chamber 1 to be transported to the filter device 4 through the outlet 102 via a pipeline for filtration. The filtered water is then transported back to the flotation chamber 1 through the inlet 101 via a pipeline, forming a water circulation. Thus, during the system's sorting process, various tiny particles mixed in with construction waste are suspended in the water and removed in time by the filter device 4, preventing them from turning the flotation cement into slurry and thus avoiding any impact on the flotation operation.

[0030] Understandably, when the mixture of lightweight construction and decoration waste is added to flotation chamber 1, the different buoyancy of materials with different densities causes heavy materials such as bricks and concrete to sink quickly, while the various lightweight materials float to the surface and are then carried by the water flow to the first transfer device 2, where they are removed from flotation chamber 1 and further utilized through a series of steps such as sorting. The heavy materials, such as bricks and concrete, sink to the bottom and are then transported to the second transfer device 3 for further processing into recycled aggregates through steps such as dewatering and crushing.

[0031] The water recycling floatation system can float out the brick and concrete materials with recycling value with high efficiency, combines waste floatation with water recycling, effectively reduces water resource consumption, increases garbage floatation efficiency, and reduces pollution and production cost.

[0032] In some embodiments, as shown in Figure 1 The floatation bin 1 has an upwardly arranged opening, for example, the floatation bin 1 is a pool structure. The input end of the first transfer device 2 and the input end of the second transfer device 3 pass through the opening of the floatation bin 1 and are placed in the water of the floatation bin 1.

[0033] Optionally, as shown in Figure 1 The first transfer device 2 is a belt conveyor, which is suitable for light material conveying. The second transfer device 3 is a screw conveyor, which is suitable for heavy material conveying.

[0034] In some embodiments, as shown in Figure 1 The bottom wall of the floatation bin 1 is arranged to be inclined, and the second transfer device 3 is attached to the bottom wall of the floatation bin 1, so as to increase the area of the second transfer device 3 on the water bottom and improve the conveying efficiency of heavy materials such as bricks and concrete.

[0035] Optionally, the inclination angle of the bottom wall of the floatation bin 1 is 15°-30°, preferably 25°, to ensure the best conveying effect of the heavy materials.

[0036] Further, as shown in Figure 1 The first transfer device 2 is arranged to be inclined, and the inclination angle of the first transfer device 2 is 25°-40°, preferably 35°, to ensure the best conveying effect of the light materials.

[0037] In some embodiments, as shown in Figure 1 The floatation bin 1 is provided with a feeding hopper 5 above the floatation bin 1, and the feeding hopper 5 continuously adds the mixed light material building decoration garbage mixture into the floatation bin 1.

[0038] In some embodiments, as shown in Figure 1 The water inlet 101 of the floatation bin 1 is arranged at the upper portion of the floatation bin 1, the water inlet 101 of the floatation bin 1 faces the first transfer device 2 and the second transfer device 3, and the water outlet 102 of the floatation bin 1 is arranged at the lower portion of the floatation bin 1.

[0039] It can be understood that the water inlet 101 is arranged at the upper side, and the water outlet 102 is arranged at the lower side, so as to realize uniform water distribution, so as to push the light materials close to the water surface to the first transfer device 2 by using the water flow.

[0040] In addition, the feeding hopper 5 is located directly above the water inlet 101 of the floatation bin 1, so that after the garbage mixture enters the water, the light materials are timely pushed by the water flow, and the separation efficiency is improved.

[0041] In some embodiments, as shown, a pressurizing pump 6 is arranged on the pipeline at the water inlet 101 side of the flotation bin 1 to increase the impact force of the water flow on the light substance, further improving the separation efficiency. Figure 1

[0042] In summary, when the system is started, the filtering device 4 starts to work first, and the pressurizing pump 6 at the water inlet 101 of the flotation bin 1 forms a water flow that rushes to the first transfer device 2 at the water surface of the flotation bin 1. At this time, the mixed light substance building decoration waste mixture is continuously added through the feeding funnel 5, and after entering the water, the heavy substances such as bricks and concretes will quickly sink due to the different buoyancy of substances with different densities, and various light substances will float to the water surface, and then be washed onto the first transfer device 2 by the water flow, and be removed from the flotation bin 1, and then be further utilized through a series of steps such as separation. The bottom of the flotation bin 1 is covered by the second transfer device 3, and the heavy substances such as bricks and concretes sink to the bottom and enter the second transfer device 3, and then are processed into recycled aggregates through steps such as dehydration and crushing.

[0043] In the separation process, various small particles mixed in the construction waste are suspended in the water, which are removed in time through the sewage filtering device 4 to avoid the cement slurry of the flotation, and prevent the impact on the flotation work. When the construction waste is continuously fed, the system continuously works without manual intervention, and has a high degree of automation.

[0044] Therefore, the water recycling flotation system directly connects the flotation bin 1 with the filtering device 4, recycles water resources, automatically cleans the flotation bin 1, does not discharge sewage, reduces pollution, and reduces cost.

[0045] The light substance is impacted by the water flow, and the light substance is effectively and quickly removed through the water immersion flotation work, high-purity aggregate raw materials are obtained, and economic benefits are improved.

[0046] The entire system has a high degree of automation, can continuously operate, has high processing capacity, and has a simple overall structure. The filtering device 4 and the flotation device are arranged in a split type, convenient to maintain, one-key start and stop, convenient to operate, and low learning cost of workers.
