Description

Technical Field

[0001] This invention belongs to the field of concrete resource utilization and specifically relates to a concrete resource recycling building. Background Technology

[0002] Concrete, as one of the most widely used building materials in the world, is extensively applied in various construction projects. However, with the advancement of urbanization, the amount of waste concrete generated is also increasing year by year. If this waste concrete is not properly disposed of, it will not only occupy a large amount of land resources but also cause environmental pollution.

[0003] The recycling of waste concrete can effectively reduce the exploitation of mineral resources and promote resource recycling and sustainable development. Traditional waste concrete processing typically involves crushing the concrete using equipment such as jaw crushers. The resulting primary crushed material is then screened for particle size adjustment. This is the simplest method for producing recycled aggregate. However, this method produces finished products with high water absorption, angular particles, and generates a significant amount of recycled powder, resulting in low overall utilization and significant limitations in practical engineering applications. Therefore, the recycling of concrete aggregate has become an urgent problem to be solved. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a concrete resource recycling building.

[0005] The present invention adopts the following technical solution:

[0007] The main building includes a main building frame, which includes a first platform, a second platform, a third platform, a fourth platform, and a fifth platform that are connected in sequence.

[0008] The crushing and screening system includes a crusher installed on a fourth platform, a grading screen installed on a third platform and connected to the crusher, a screening discharge pipe installed on a second platform, a fine sand separator installed on a first platform and connected to the screening discharge pipe, a first gravity meter installed on a first platform and connected to the screening discharge pipe, and a second gravity meter installed on a first platform and connected to the screening discharge pipe.

[0009] Furthermore, the screening discharge pipe includes a first discharge port, a second discharge port and a third discharge port, the fine sand separator is connected to the first discharge port, the first gravity meter is connected to the second discharge port, and the second gravity meter is connected to the third discharge port.

[0010] Furthermore, the crushing and screening system also includes a first aggregate conveyor and a second aggregate conveyor disposed on the second platform. The first aggregate conveyor is connected between the second discharge port and the first gravity meter, and the second aggregate conveyor is connected between the third discharge port and the second gravity meter.

[0011] Furthermore, the crushing and screening system also includes a first transition chamber and a second transition chamber disposed on the second platform. The first transition chamber is disposed between the second discharge port and the first aggregate conveyor, and the second transition chamber is disposed between the third discharge port and the second aggregate conveyor.

[0012] Furthermore, the raw material lifting system includes a receiving hopper, an elevator connected to the receiving hopper and installed on one side of the circulating main building, a crushing feed chute connected to the elevator outlet, a screening feed chute connected to the crushing feed chute, an elevator railing installed on top of the elevator, and a fixed frame installed between the elevator railing and the circulating main building. The crushing feed chute includes a first discharge port and a second discharge port. The screening feed chute is connected to the first discharge port, and the crusher is connected to the second discharge port.

[0013] Furthermore, the screening discharge pipe also includes a fourth discharge port, and the receiving hopper is connected to the fourth discharge port. The concrete that is larger than the predetermined particle size after being processed by the grading screen is discharged into the receiving hopper through the fourth discharge port.

[0014] Furthermore, the main circulation building also includes a climbing staircase connected to a fixed frame on the fifth platform.

[0015] Furthermore, the batching system includes a raw material silo for storing concrete raw materials and a raw material conveyor connecting the raw material silo and the raw material lifting system.

[0017] Furthermore, it also includes control systems that are connected to the batching system, raw material lifting system, dust removal system, and crushing and screening system, respectively.

[0018] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are as follows: By defining the structural composition of the resource recycling tower, the present application integrates batching, lifting, dust removal, crushing and screening on the main recycling tower to obtain finished materials with low water absorption, good particle shape and less recycled powder, which greatly improves the utilization rate of concrete raw materials; it saves energy and reduces emissions, avoiding the consumption of a large amount of energy and emission of a large amount of greenhouse gases like in the traditional concrete production process; in addition, the overall production cost is low, which can effectively reduce construction costs, improve engineering efficiency, increase economic benefits, effectively recycle waste concrete, reduce the demand for new resources, and alleviate resource shortages.
