Description

Technical Field

[0001] This utility model relates to the field of recycled concrete, and in particular to a device for preparing highly permeable and environmentally friendly concrete using recycled aggregates. Background Technology

[0002] Concrete, as the building material used by humans in the largest quantities, has seen its theory and technology become increasingly mature. However, the large-scale application of concrete has brought negative impacts on the living environment and ecosystem. Urban demolition and engineering renovation have also resulted in the disposal of a large amount of concrete, which wastes a lot of land resources and pollutes the environment. Concrete made by crushing and classifying the concrete from old buildings or structures into coarse and fine aggregates to replace some of the sand and gravel in the concrete mix is ​​called recycled aggregate concrete.

[0003] A search revealed that patent CN222201075U discloses a green building material concrete preparation device, including a preparation bucket, multiple support legs fixedly installed at the bottom of the preparation bucket, and a dust cover fixedly installed at the top of the preparation bucket. A feed inlet is located on the front side of the dust cover. A stirring rod is rotatably installed inside the preparation bucket. The rear end of the feed inlet communicates with the interior of the dust cover, which contains a dust-proof component. By incorporating the dust-proof component, the feed inlet can be sealed to prevent concrete from flying into the environment during mixing. This avoids the possibility of dust insulated from the outside environment causing injury to workers, thus protecting both the construction site environment and the workers' health.

[0004] Existing equipment continuously crushes concrete by rotating a mixing rod, but the distance between the mixing rod and the preparation tank is constant, making it impossible to gradually crush the concrete. This easily leads to concrete clogging between the preparation tank and the mixing rod, causing the equipment to stop.

[0005] Therefore, it is necessary to provide a device for preparing highly permeable and environmentally friendly concrete using recycled aggregates to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a device for preparing highly permeable and environmentally friendly concrete using recycled aggregates.

[0007] This utility model provides a device for preparing highly permeable and environmentally friendly concrete using recycled aggregate, which includes a sorting box.

[0009] In order to increase the bottom extrusion friction, this utility model provides a device for preparing highly permeable and environmentally friendly concrete using recycled aggregate. Preferably, a number of mounting bolts are evenly arranged through the bottom of the periphery of the top cover, and a crushing plate is provided at one end of each of the mounting bolts that is close to each other.

[0010] In order to achieve the effect of gradually narrowing the compaction space, this utility model provides a device for preparing high-permeability environmentally friendly concrete using recycled aggregate. Preferably, the top cover has a feed inlet, the top cover is a conical hollow body, and the rotating roller is a conical solid body.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of a recycled aggregate high-permeability environmentally friendly concrete preparation device provided by this utility model; Figure 2 for Figure 1 The diagram shows a frontal sectional view of the structure. Figure 3 for Figure 1 The diagram shows a top view of the crushing plate.

[0024] Figure 4 for Figure 2 The schematic diagram of the rotating roller shown includes a device for preparing highly permeable and environmentally friendly concrete using recycled aggregates, including a sorting box 1, a crushing structure 2 on the top of the sorting box 1, and a sorting structure 3 inside the sorting box 1.

[0025] In the specific implementation process, refer to Figure 2 , Figure 3 and Figure 4 As shown, the crushing structure 2 includes a connection port 201 at the top of the sorting box 1. A top cover 202 is provided around the connection port 201. A fixing plate 205 is provided between the connection ports 201. A motor 206 is provided at the bottom of the fixing plate 205. The top of the motor 206 extends through the fixing plate 205 via a drive shaft and is connected to a rotating roller 207. Several rotating crushing plates 208 are evenly arranged around the rotating roller 207. Several mounting bolts 203 are evenly arranged through the bottom of the top cover 202. A crushing plate 204 is provided at the end of each mounting bolt 203 that is close to each other. A feed port 209 is provided at the top of the top cover 202. The top cover 202 is a conical hollow body. The rotating roller 207 is a conical solid body. The sorting box 1 is a box with an open bottom. Support legs 4 are provided at the four corners of the bottom of the sorting box 1.

[0026] It should be noted that: concrete is added into the top cover 202 through the feed inlet 209, and the motor 206 controls the rotating roller 207 at the top of the rotating shaft. Several rotating crushing plates 208 around the rotating roller 207 continuously crush the concrete. Because the top cover 202 is a conical hollow body and the rotating roller 207 is a conical solid body, the gap between the falling parts gradually decreases, and with the help of several crushing plates 204, fine crushing is carried out.

[0027] In the specific implementation process, refer to Figure 1 and Figure 2 As shown, the sorting structure 3 includes a sorting screen plate 301 that is inclinedly installed inside the sorting box 1 on the left side via a hinge. Two telescopic rods 302 are symmetrically arranged at the bottom of the other end of the sorting screen plate 301. Guide sleeves 303 are inserted into the bottom ends of the two telescopic rods 302. Reset springs 304 are provided on the outside of the two telescopic rods 302. The bottom ends of the two guide sleeves 303 are located in the sorting box 1. A non-conforming discharge port 305 is opened on the left side of the sorting box 1 and at the top of the sorting screen plate 301. A discharge plate 306 is inclinedly arranged at the bottom end of the sorting box 1 and at the end away from the non-conforming discharge port 305.

[0028] It should be noted that: the crushed concrete blocks are discharged through the connection port 201 and fall to impact the sorting screen plate 301. The impact force is transmitted to the two return springs 304, causing the sorting screen plate 301 to swing downward. Then, the qualified concrete blocks pass through the sorting screen plate 301 and fall to the discharge plate 306. The two return springs 304 are reset, causing the two telescopic rods 302 to slide along the corresponding guide sleeves 303. The unqualified concrete blocks slide through the sorting screen plate 301 and are discharged through the unqualified discharge port 305.

[0029] The working principle of the recycled aggregate high-permeability environmentally friendly concrete preparation device provided by this utility model is as follows:

[0030] In use, concrete is added into the top cover 202 through the feed inlet 209. The motor 206 controls the rotating roller 207 at the top of the rotating shaft. Several rotating crushing plates 208 around the rotating roller 207 continuously crush the concrete. Because the top cover 202 is a conical hollow body and the rotating roller 207 is a conical solid body, the gap between the falling concrete gradually decreases. Combined with several crushing plates 204, the concrete is finely crushed. The crushed concrete blocks are discharged through the connection port 201 and fall to impact the sorting screen plate 301. The impact force is transmitted to two return springs 304, causing the sorting screen plate 301 to swing downward. Then, the qualified concrete blocks pass through the sorting screen plate 301 and fall to the discharge plate 306. The weight of the concrete on the sorting screen plate 301 is reduced, and the two return springs 304 reset, causing the two telescopic rods 302 to slide along the corresponding guide sleeves 303. The unqualified concrete blocks slide through the sorting screen plate 301 and are discharged through the unqualified discharge port 305.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
