Description

Technical Field

[0001] The utility model relates to the technical field of aggregate recovery, in particular to an aggregate purifier. Background Technique

[0002] With the development of the economy and the advancement of urban construction, more and more concrete structure buildings are demolished due to reaching the service life or failing to meet the application requirements, thus generating a large amount of waste concrete. After the waste concrete is screened, the aggregates can be reused.

[0003] However, on the one hand, a large number of light substances mixed in the waste concrete are difficult to separate, resulting in a low purity of the finished aggregates. On the other hand, the aggregates are divided into fine aggregates and coarse aggregates. The particle diameter of the fine aggregates is between 0.16 and 5 mm, generally natural sand, and the particle diameter of the coarse aggregates is greater than 5 mm. Commonly used ones are crushed stones and pebbles. In the prior art, after removing the light substances, it is also necessary to secondarily sort the specifications of the aggregates, and the operation is relatively cumbersome.

[0004] Therefore, in view of this, in view of the deficiencies of the existing structure, research and improvement are carried out, and an aggregate purifier is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an aggregate purifier to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an aggregate purifier, including a machine body and a vibration screening assembly. The vibration screening assembly is fixed at the bottom end inside the machine body. The vibration screening assembly includes a frame, a vibrator, a fine aggregate sieve plate, a coarse aggregate sieve plate and screening holes. The frame is connected to the machine body through buffer springs, and a vibrator is arranged on the side wall of the frame. The lower layer of the frame is provided with a fine aggregate sieve plate, and the upper layer of the frame is provided with a coarse aggregate sieve plate. The bottom end of the coarse aggregate sieve plate is evenly distributed with screening holes with a diameter of 5MM.

[0007] Further, the coarse aggregate sieve plate located in the upper layer is communicated with the fine aggregate sieve plate located in the lower layer through the screening holes, and the outlet directions of the coarse aggregate sieve plate and the fine aggregate sieve plate are opposite.

[0008] Further, one side of the top of the machine body is communicated with a dust collection air hood, and the other side of the top of the machine body is provided with a feed inlet.

[0009] Further, a pneumatic separation and screening assembly is arranged at the top end inside the machine body. The pneumatic separation and screening assembly includes a bracket and an aggregate conveyor belt. The bracket is welded and fixed to the side wall of the machine body, and the top of the bracket receives the aggregate conveyor belt.

[0010] Furthermore, the air separation and screening component also includes a blower and an air duct. The bottom of the bracket is provided with a blower, and the inlet end of the blower is connected to the outside of the body, and the outlet end of the blower is connected to the air duct.

[0011] Furthermore, the air separation and screening assembly also includes a partition and a roller, the end of the air duct is connected to the partition, and a roller is arranged on the top side of the partition, and there is a large gap between the roller and the aggregate conveyor belt for aggregate to fall and high-speed airflow to pass through.

[0012] Furthermore, the air separation and screening assembly also includes a baffle and a lightweight discharge belt. The baffle is obliquely arranged on the top of the roller, and the lightweight discharge belt is arranged on the side of the roller away from the aggregate conveyor belt.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When the utility model is in use, waste concrete is put into the aggregate conveyor belt from the feed port, and the aggregate mixed with light materials falls from the gap between the end of the aggregate conveyor belt and the roller. During this period, under the action of high-speed airflow, the light materials mixed in the aggregate are stripped off and fall onto the light discharging belt under the action of the baffle, while the heavier aggregates will settle down and fall into the vibrating screening component to wait for further screening. Through the setting of the wind screening component, the light materials contained in the finished aggregate are separated by wind, thereby improving the purity of the finished aggregate.

[0015] 2. When the utility model is in use, the centrifugal inertia force generated by the vibrator causes the frame to vibrate, and the aggregate is thrown and moved forward on the screen surface. The fine aggregate and the coarse aggregate are sorted through the screening holes with a diameter of 5MM at the bottom of the coarse aggregate screen plate. The fine aggregate will pass through the screening holes and fall onto the fine aggregate screen plate located at the lower layer, so that the fine aggregate and the coarse aggregate are discharged from the outlets on the opposite sides respectively. By continuously vibrating and screening the aggregate on the basis of wind selection screening, the aggregate is further classified according to coarseness and fineness, thereby reducing the subsequent labor intensity. In addition, the light objects, fine aggregates and coarse aggregates have different outlets for easy collection and sorting. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] As Figures 1 to 3 shown, an aggregate purification machine includes a machine body 1 and a vibrating screening assembly 5. The vibrating screening assembly 5 is fixed to the bottom end inside the machine body 1. The vibrating screening assembly 5 includes a frame 501, a vibrator 502, a fine aggregate sieve plate 503, a coarse aggregate sieve plate 504, and screening holes 505. The frame 501 is connected to the machine body 1 through buffer springs, and a vibrator 502 is provided on the side wall of the frame 501. A fine aggregate sieve plate 503 is provided on the lower layer of the frame 501, and a coarse aggregate sieve plate 504 is provided on the upper layer of the frame 501. Screening holes 505 with a diameter of 5MM are evenly distributed at the bottom end of the coarse aggregate sieve plate 504. The coarse aggregate sieve plate 504 located on the upper layer is communicated with the fine aggregate sieve plate 503 located on the lower layer through the screening holes 505, and the outlets of the coarse aggregate sieve plate 504 and the fine aggregate sieve plate 503 face in opposite directions. The frame 501 generates vibrations through the centrifugal inertial force generated by the vibrator 502. The aggregate generates throwing and forward movements on the sieve surface. The fine aggregate and the coarse aggregate are separated through the screening holes 505 with a diameter of 5MM at the bottom of the coarse aggregate sieve plate 504. The fine aggregate will pass through the screening holes 505 and fall onto the fine aggregate sieve plate 503 located on the lower layer, so that the fine aggregate and the coarse aggregate are discharged from the outlets on the two opposite sides respectively. By continuously vibrating and screening the aggregate on the basis of air separation and screening, the aggregate is further classified according to thickness, reducing the subsequent labor intensity, and the different outlets for lightweight materials, fine aggregate, and coarse aggregate are convenient for collection and sorting;

[0022] As Figures 1 to 2As shown, a dust collecting hood 2 is connected to one side of the top of the machine body 1, and a feed port 3 is opened on the other side of the top of the machine body 1. A pneumatic screening component 4 is arranged at the top of the machine body 1. The pneumatic screening component 4 includes a bracket 401 and an aggregate conveyor belt 402. The bracket 401 is welded and fixed to the side wall of the machine body 1, and the aggregate conveyor belt 402 is supported on the top of the bracket 401. The pneumatic screening component 4 also includes a blower 403 and an air duct 404. The blower 403 is arranged at the bottom of the bracket 401, and the inlet end of the blower 403 is connected to the outside of the machine body 1, and the outlet end of the blower 403 is connected to the air duct 404. The pneumatic screening component 4 also includes a partition 405 and a roller 406. The end of the air duct 404 is supported by the partition 405, and the roller 406 is arranged on the top side of the partition 405, and the roller 406 is connected to the aggregate conveyor belt 40 2, there is a large gap between the aggregate and the roller 406 for the aggregate to fall and the high-speed airflow to pass through. The air separation and screening component 4 also includes a baffle 407 and a light discharge belt 408. The baffle 407 is inclinedly arranged on the top of the roller 406, and the light discharge belt 408 is arranged on the side of the roller 406 away from the aggregate conveyor belt 402. The waste concrete is fed into the aggregate conveyor belt 402 from the feed port 3, and the aggregate mixed with light materials falls from the gap between the end of the aggregate conveyor belt 402 and the roller 406. During this period, under the action of the high-speed airflow, the light materials mixed in the aggregate are stripped off and fall into the light discharge belt 408 under the action of the baffle 407, while the heavier aggregates will settle down and fall into the vibrating screening component 5 to wait for further screening. Through the setting of the air separation and screening component 4, the light materials contained in the finished aggregate are separated by air separation to improve the purity of the finished aggregate.

[0023] Working principle: When using this aggregate purifier, the waste concrete is put into the aggregate conveyor belt 402 from the feed port 3, and the aggregate mixed with light materials falls from the gap between the end of the aggregate conveyor belt 402 and the roller 406. During this period, under the action of high-speed airflow, the light materials mixed in the aggregate are stripped off and fall onto the light discharge belt 408 under the action of the baffle 407, while the heavier aggregates will settle and fall into the vibrating screening component 5 to wait for further screening. Through the setting of the wind screening component 4, the light materials contained in the finished aggregate are separated by wind, the purity of the finished aggregate is improved, and the vibration is used to separate the light materials contained in the finished aggregate. The centrifugal inertia force generated by the device 502 causes the frame 501 to vibrate, and the aggregate is thrown and moved forward on the screen surface. Fine aggregate and coarse aggregate are sorted through the screening holes 505 with a diameter of 5MM at the bottom of the coarse aggregate screen plate 504. The fine aggregate will pass through the screening holes 505 and fall onto the fine aggregate screen plate 503 located at the lower layer, so that the fine aggregate and coarse aggregate are discharged from the outlets on the opposite sides respectively. By continuously vibrating and screening the aggregate on the basis of wind selection screening, the aggregate is further classified according to coarseness and fineness, thereby reducing the subsequent labor intensity. In addition, the light objects, fine aggregates and coarse aggregates have different outlets for easy collection and sorting.
