Description

Technical Field

[0001] This utility model relates to the field of crushing and recycling technology, specifically a waste recycling device for concrete production lines. Background Technology

[0002] During the concrete production process, concrete waste may be generated due to issues such as substandard components, storage, overproduction, and scraps. The crushed concrete blocks can be used as roadbed filler or raw material for lightweight aggregate concrete, as well as for manufacturing recycled bricks, blocks, or low-strength concrete.

[0003] Existing concrete crushing and recycling equipment typically uses jaw crushers for crushing. The main structure of a jaw crusher achieves crushing through the reciprocating movement of a moving jaw plate. This causes concrete waste to be crushed by the force applied between the moving and fixed jaw plates. During this process, as the moving jaw plate moves away from the fixed jaw plate, the gap between them increases, allowing material to enter between the moving and fixed jaw plates. Subsequently, the moving jaw plate moves closer to the fixed jaw plate to crush the concrete waste. However, when the moving jaw plate moves away from the fixed jaw plate, it does not crush the concrete waste, resulting in a defect in the continuity of crushing in the jaw crusher. To address this, we propose a waste recycling device for concrete production lines. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are: the waste recycling device of this concrete production line,

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model embodiment provides a waste recycling device for concrete production lines, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes barrel body 1;

[0024] The fixed crushing component 2 includes a fixed toothed plate 201. Multiple fixed toothed plates 201 are arranged in a ring array around the central axis of the barrel 1. The outer ring surface of multiple fixed toothed plates 201 arranged in a circle is fixedly connected to the inner ring wall of the barrel 1. The gap between each pair of adjacent fixed toothed plates 201 forms a groove 202.

[0025] The movable crushing assembly 3 includes a rotating roller 301. Multiple annularly distributed crushing strips 302 are fixedly connected to the side surface of the rotating roller 301. A ball joint 303 is fixedly connected to the bottom of the rotating roller 301. A movable sleeve 305 is movably fitted onto the side surface of the ball joint 303. A fixed base 306 is fixedly connected to the bottom of the movable sleeve 305. An extension platform 304 is fixedly connected to the top of the rotating roller 301. In use, concrete waste is fed into the barrel 1 through the feeding chute 403. Then, the drive motor 503 is started. As the output shaft of the drive motor 503 rotates, the rotating roller 301 rotates through the ball joint 303 and the movable sleeve 305. Because the rotating roller 301 is inclined, it... One side of the rotating roller 301 is always close to the inner ring surface of the circle formed by multiple fixed toothed plates 201, while the opposite side of the rotating roller 301 is away from the inner ring surface. At this time, most of the material accumulates between the rotating roller 301 and the inner ring surface of the circle formed by multiple fixed toothed plates 201. As the rotating roller 301 rotates, the friction between the material and the concrete block is increased by the multiple fixed toothed plates 201 and multiple crushing bars 302. The concrete block is gradually crushed under the action of compression and friction by the fixed toothed plates 201 and the crushing bars 302, and falls into the feeding bin 405 through the groove 202 between the fixed toothed plates 201 and the crushing bars 302. It is then guided by the inclined plate 401 so that the crushed concrete waste is discharged from the discharge port 402.

[0026] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top and bottom of the barrel 1 are provided with loading and unloading components 4. The loading and unloading components 4 include a feeding bin 405. The top of the feeding bin 405 is fixedly connected to the bottom of the barrel 1 and the feeding bin 405 and the barrel 1 are in communication. An inclined plate 401 for guiding crushed waste is fixedly sleeved on the inner ring surface of the feeding bin 405. A discharge port 402 is opened at the bottom of the side surface of the feeding bin 405. A feeding trough 403 is fixedly connected to one side of the top of the barrel 1. An inclined brace 404 is fixedly connected between the bottom of the feeding trough 403 and the side surface of the barrel 1.

[0027] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a power assembly 5 is provided on the top of the barrel 1. The power assembly 5 includes a longitudinal beam 501. The bottom of the longitudinal beam 501 is fixedly connected to one side of the top of the barrel 1. A crossbeam 502 is fixedly connected to the top of the longitudinal beam 501. A drive motor 503 is fixedly connected to the bottom of the crossbeam 502.

[0028] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the extension platform 304 is fixedly connected to the end of the output shaft of the drive motor 503. The output shaft of the drive motor 503 is not concentric with the rotating roller 301. By fixing the crushing component 2 and the movable crushing component 3, the inclined rotating roller 301 rotates in an inverted conical trajectory under the power drive of the drive motor 503. This allows the rotating roller 301 to continuously crush the concrete while rotating, providing better crushing continuity and improving crushing efficiency compared to traditional jaw crushers. By fixing the crushing component 2 and the movable crushing component 3, the rotating roller 301 continuously crushes the concrete, thereby improving energy utilization efficiency. While achieving continuous crushing, it reduces energy consumption and improves energy utilization efficiency compared to traditional jaw crushers. In addition, the fixed jaw plate and movable jaw plate of traditional jaw crushers are arranged horizontally, resulting in a large area occupied by the equipment. However, this invention uses a circular fixed toothed plate 201 and a rotating roller 301 rotating around a ball joint 303 to crush concrete waste, reducing the area occupied and optimizing the size of the device.

[0029] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom inner wall of the feeding bin 405 is fixedly connected to the bottom of the fixed seat 306, and the discharge port 402 is located at the bottom of the inclined plate 401.

[0030] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the rotating roller 301 is inclined. The rotating roller 301 is driven by the drive motor 503 and rotates with the ball joint 303 as the center. The rotation trajectory of the rotating roller 301 is an inverted cone shape.

[0031] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top of the fixed tooth plate 201 is narrower than the bottom of the fixed tooth plate 201, the top of the fixed tooth plate 201 is an inclined surface, and the top of the circle formed by multiple fixed tooth plates 201 is an inverted cone.

[0032] Working principle: During use, concrete waste is fed into the barrel 1 through the feeding chute 403. Then, the drive motor 503 is started. As the output shaft of the drive motor 503 rotates, the rotating roller 301 rotates through the ball joint 303 and the movable sleeve 305. Because the rotating roller 301 is inclined, one side of the rotating roller 301 is always close to the inner ring surface formed by the multiple fixed toothed plates 201, while the opposite side of the rotating roller 301 is away from the inner ring surface. At this time, most of the material accumulates in the inner ring surface. The rotating roller 301 is located away from the inner ring surface formed by the multiple fixed toothed plates 201. As the rotating roller 301 rotates, the friction between the roller and the concrete block increases through the multiple fixed toothed plates 201 and the multiple crushing strips 302. This causes the concrete block to be gradually crushed under the action of compression and friction between the fixed toothed plates 201 and the crushing strips 302. The crushed concrete block then falls into the discharge bin 405 through the groove 202 between the fixed toothed plates 201 and the crushing strips 302. It is then guided by the inclined plate 401, allowing the crushed concrete waste to be discharged from the discharge port 402.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
