Description

Technical Field

[0001] This utility model relates to the technical field of construction waste treatment equipment, specifically a construction waste recycling and reuse equipment. Background Technology

[0002] With the rapid advancement of urbanization, the total amount of construction waste (such as concrete blocks, bricks, and slag) generated during building demolition, renovation, and construction is increasing year by year. If this construction waste is dumped directly without treatment, it not only occupies a large amount of land resources but also causes soil and water pollution due to dust pollution and rainwater runoff, negatively impacting the ecological environment. Therefore, the recycling and reuse of construction waste has become an important measure to achieve resource recycling and environmental protection. Cleaning, as a key step in the pretreatment of construction waste, directly affects the purity and subsequent utilization value of recycled aggregates.

[0003] A search revealed that Chinese patent application number CN202420714745.3 discloses a construction waste recycling and reprocessing equipment, including a washing tank and a collection tank. The washing tank and the collection tank are connected. A washing mechanism is installed on the washing tank for washing the construction waste placed in the washing tank. A filtration mechanism is installed in the collection tank for filtering the washing water flowing into the washing tank. This utility model filters and reuses the washing water to rinse the construction waste, which can reduce water consumption, improve water resource utilization, and improve washing quality.

[0004] The above-mentioned utility model has the following problems:

[0005] 1. Poor cleaning effect, with impurities easily remaining in the material: The core problem lies in the lack of an active turning or stirring structure for the construction waste in the cleaning tank. Relying solely on the rotating rinsing of the spray nozzles above is insufficient to effectively wash away stubborn impurities such as mud and oil stains from the surface and crevices of the material. For large pieces of concrete, bricks, and other construction waste, their stacked state creates cleaning blind spots at the bottom and contact surfaces, preventing the thorough removal of impurities. This directly affects the purity and quality of subsequent recycled aggregates. Especially when construction waste is adhered to with clay or paint residue, static stacking cleaning methods are insufficient to meet high cleanliness requirements.

[0006] 2. The filtration mechanism is inefficient, prone to clogging, and difficult to maintain: The filtration mechanism relies on a single filter screen to achieve solid-liquid separation. Mud and fine particulate impurities in the washing water can easily accumulate on the surface of the filter screen, resulting in a decrease in filtration speed or even clogging of the filter screen, which affects the water circulation efficiency.

[0007] Therefore, those skilled in the art have provided a construction waste recycling and reuse device to solve the problems mentioned in the background art. Utility Model Content

[0008] The purpose of this utility model is to provide a construction waste recycling and reuse device to solve the problems mentioned in the background art.

[0025] Example 1

[0026] Reference Figures 1-5 This embodiment provides a construction waste recycling and reuse device, including a cleaning chamber 1. The cleaning chamber 1 is a cuboid cavity with an open upper end and a water collection chamber 2 fixedly connected to the lower end. The water collection chamber 2 is a conical cavity with a cylindrical sedimentation tank 4 at its bottom. Bearing seats 8 are fixedly installed at both ends of the upper length direction of the cleaning chamber 1. A rotating shaft 14 is rotatably installed between the two bearing seats 8. An inclined cylindrical screen 13 is fixedly installed on the rotating shaft 14. The diameter and length of the screen 13 are adapted to the inner length of the cleaning chamber 1. A support plate 2 15 is fixedly installed on one side of the cleaning chamber 1. A pump body 16 is fixedly installed at the upper end of the support plate 2 15. A water outlet pipe 17 is fixedly connected to the output end of the pump body 16. The water outlet pipe 17 extends to the top of the screen 13 and a drain pipe 18 is fixedly connected to the end of the drain pipe 18 along the length direction of the screen 13. Several nozzles 19 are fixedly connected to the lower end of the drain pipe 18.

[0027] Furthermore, the pump body 16 is fixedly connected to a suction pipe 20 at its input end. The suction pipe 20 extends through the water collection chamber 2 and is fixedly connected to a filter cover 21 with a built-in filter screen at its port. Support legs 3 are welded to the cleaning chamber 1 near the four corners.

[0028] Furthermore, the drain pipe 18 is a horizontally arranged metal pipe with the same length as the screen 13, and several nozzles 19 are evenly distributed along the length of the drain pipe 18.

[0029] Furthermore, the filter cover 21 is a cylindrical stainless steel shell, and the built-in filter screen has a double-layer structure, with the upper layer being a stainless steel filter screen and the lower layer being an activated carbon adsorption layer. The filter cover 21 and the port of the water suction pipe 20 are detachably connected by threads.

[0030] Example 2

[0031] Reference Figures 1-5 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that one end of the sedimentation tank 4 extends into the water collection chamber 2 and is threadedly connected to the sealing cover 7. The sedimentation tank 4 is provided with an auger 6, and a drive motor 5 is fixedly installed at one end of the sedimentation tank 4. The output shaft of the drive motor 5 is fixedly connected to the auger 6.

[0032] Furthermore, an arc-shaped through groove 9 is provided at one end of the cleaning chamber 1 at the lower end of the screen 13. An arc-shaped guide plate 10 is fixedly installed in the arc-shaped through groove 9. One end of the arc-shaped guide plate 10 extends into the cleaning chamber 1 and is located directly below the lower end of the screen 13, while the other end extends obliquely to the outside of the cleaning chamber 1.

[0033] Furthermore, a support plate 11 is fixedly installed at the end of the cleaning chamber 1 away from the arc-shaped through groove 9, and a motor 12 is fixedly installed at the upper end of the support plate 11. The output shaft of the motor 12 is fixedly connected to the end of the rotating shaft 14 away from the bearing seat 8 through a coupling.

[0034] Working principle: Construction waste is fed into the upper end of the inclined cylindrical screen 13. The motor 12 drives the rotating shaft 14 to rotate on the bearing seat 8 through the coupling, causing the screen 13 to rotate. This causes the construction waste to tumble and move towards the lower end of the screen 13 as it rotates. At the same time, the pump body 16 on the support plate 2 draws filtered water from the water collection chamber 2 through the suction pipe 20 and the filter cover 21 with a built-in double-layer filter screen. The water is then transported through the outlet pipe 17 to the drain pipe 18 directly above the screen 13, and then sprayed out by several nozzles 19 to clean the tumbled construction waste. The waste is rinsed from all sides, and the wastewater falls through the mesh of the screen 13 into the lower rectangular cleaning chamber 1 and flows into the conical water collection chamber 2. The sludge settles in the sedimentation tank 4. The drive motor 5 drives the auger 6 to push the sludge to the end of the sedimentation tank 4. The sludge can be discharged by opening the threaded sealing cover 7. The purified water remains in the water collection chamber 2 for pump body 16 to circulate and pump. The cleaned construction waste falls through the lower end of the screen 13 into the arc-shaped guide plate 10 in the arc-shaped channel 9, slides out of the cleaning chamber 1 through the guide plate, and is transported out by the lower conveying mechanism.
