Abstract
Description
Technical Field
[0001] This utility model relates to the field of recycled aggregate concrete production technology, specifically to an impurity separation device for recycled aggregate concrete production. Background Technology
[0002] Recycled aggregate is a granular material produced from construction waste such as concrete and bricks through crushing and screening processes. Based on particle size, it is divided into recycled coarse aggregate and recycled fine aggregate, and can replace natural aggregate in applications such as subgrade soil improvement, mortar preparation, and recycled concrete. Its production process includes pretreatment to separate impurities, multi-stage crushing, particle size screening, and surface modification.
[0003] The existing technology has the following problems:
[0004] During the process of crushing waste concrete, some steel bars are mixed with the concrete and crushed together, resulting in the presence of some metal impurities in the crushed concrete. Some of these metal impurities can affect the quality of the recycled aggregate concrete, thus impacting its usability. When the concrete is not crushed sufficiently, it is easy for metal blocks to be embedded within the concrete blocks, and this type of concrete cannot be effectively separated. This can easily lead to the metal blocks embedded in the concrete blocks remixing with the crushed concrete.
[0005] Therefore, we need an impurity separation device for recycled aggregate concrete production to solve the above problems. Utility Model Content
[0006] This invention provides an impurity separation device for the production of recycled aggregate concrete to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0008] An impurity separation device for recycled aggregate concrete production includes a box body and a connecting assembly. The upper part of the middle of the left and right sides of the box body is provided with an impurity discharge port that communicates with the inside and outside. The middle of the upper surface of the box body is provided with a material inlet. A feeding hopper is fixedly connected to the side of the upper surface of the box body near the material inlet. A control panel is fixedly connected to the upper front of the box body.
[0009] A connecting component two is fixedly connected to the upper part of the inner wall of the box, and a material collection frame is fixedly connected to the lower surface of the inner wall of the box. A discharge port with internal and external communication is opened in the middle of the lower surface of the inner wall of the box. The connecting component two includes two electromagnets. Two mounting plates are fixedly connected to the lower surface of the left and right electromagnets in a mirror image. The two mounting plates are in an inclined state, and an outlet is opened on the side of the left and right mounting plates near the electromagnets.
[0010] A further improvement of this utility model is that: two guide plates are fixedly connected to the lower surface of the mounting plates on the left and right sides in a mirror image, the two guide plates are in an inclined state, and the lower surface of the outer surface of the guide plates on the left and right sides corresponds to the interior of the impurity discharge port.
[0011] A further improvement of this utility model is that: two protective plates are fixedly connected to the outer surfaces of the mounting plates on the left and right sides in a mirror-like manner. The two protective plates are similar to an L shape, and the upper part of the outer surfaces of the two protective plates is in an inclined state.
[0012] A further improvement of this utility model is that a sliding groove is provided in the middle of the opposite surfaces of the two protective plates.
[0013] A further improvement of the present invention is that the connecting component includes two frame frames, which form a V-shape. A limiting opening is formed below the opposite surfaces of the two frame frames, and a mesh plate is fixedly connected to the inner side of each of the two frame frames.
[0014] A further improvement of this utility model is that: reinforcing plates are fixedly connected to the front and rear sides of the upper surfaces of the two frame frames, and strip blocks are fixedly connected to the outer surfaces of the two frame frames near the protective plate, and the outer surfaces of the left and right strip blocks are respectively slidably connected to the inside of the slide groove.
[0015] A further improvement of this utility model is that a plate is fixedly connected to the front side of the reinforcing plate, and a U-shaped handle is fixedly connected to the front side of the plate.
[0016] A further improvement of this utility model is that the outer surface of the plate is slidably connected to the outside of the box.
[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0018] 1. This utility model provides an impurity separation device for the production of recycled aggregate concrete. When the crushed concrete enters the interior of the box and falls downwards, the metal block impurities in the concrete are adsorbed onto the surface by the setting of electromagnets on the left and right sides. When the electromagnets are de-energized, the surface magnetism disappears. Due to the influence of gravity, the metal block impurities fall downwards and pass through the outlet. With the cooperation of the guide plate and the impurity discharge outlet, the metal impurities are discharged. The structure achieves the effect of removing metal impurities mixed in the concrete.
[0019] 2. This utility model provides an impurity separation device for recycled aggregate concrete production. The mesh plate allows the crushed concrete to fall directly downwards. When encountering a metal block wrapped in a larger concrete block, the mesh plate acts as a barrier, causing the larger concrete block to stop at the limiting opening formed by the frame on the left and right sides. The limiting opening also facilitates the passage and downward fall of the crushed concrete, preventing its accumulation. This structure achieves the interception and separation of metal impurities wrapped in larger concrete blocks. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] Example 1:
[0027] like Figures 1 to 4 As shown, this utility model provides an impurity separation device for recycled aggregate concrete production. It adopts a cubic box 1 with impurity discharge outlets 2 symmetrically opened on the upper part of the middle of the left and right sides of the box 1. The impurity discharge outlets 2 facilitate the discharge of metal impurities. A rectangular material inlet is opened in the middle of the upper surface and a feed hopper 3 is welded and fixed to facilitate the entry of crushed concrete.
[0028] The control panel is bolted to the front of the housing 1. The control panel, wires, electromagnet 51, and power supply are electrically connected to facilitate the on / off state of the electromagnet 51. Inside, the upper part is welded to the connecting assembly 5, and the bottom is welded to the collecting frame 6 with a discharge port 7. The discharge port 7 allows concrete after the separation of metal impurities to be discharged. The inner side of the collecting frame 6 is provided with inclined surfaces, which are mirrored front-to-back and left-to-right. These inclined surfaces allow the concrete to be discharged directly through the discharge port 7, preventing excessive accumulation of concrete at the bottom of the housing 1.
[0029] Example 2:
[0030] Based on Embodiment 1, the connecting component 2 5 consists of two electromagnets 51 forming a core separation unit. The electromagnets 51 are installed and fixed to the upper sides of the inner wall of the housing 1. An inclined mounting plate 52 is welded below each electromagnet 51. The two mounting plates 52 are arranged in an inverted V-shape, with an outlet 53 on the side closest to the electromagnet 51. The outlet 53 facilitates the discharge of metal impurities by allowing them to fall downwards after the electromagnet 51 is closed. A guide plate 56 is welded below the mounting plate 52. The guide plate 56 is inclined at an angle adapted to the mounting plate 52, forming a V-shape. Its end extends to the inner side of the impurity discharge outlet 2, forming a flow channel, allowing metal impurities to slide downwards on the surface of the guide plate 56 and be discharged through the impurity discharge outlet 2.
[0031] Two protective plates 54 are fixedly connected to the outer surface of the left and right mounting plates 52 in a mirror-like manner. The two protective plates 54 are L-shaped and the upper part of the outer surface of the two protective plates 54 is inclined. The shape of the protective plates 54 can protect the outlet 53 and prevent the broken concrete from entering from the outlet 53. The middle of the opposite surface of the two protective plates 54 is provided with a groove 55. The groove 55 facilitates the sliding connection and installation of the strip block 42 inside, and facilitates the installation and removal of the connecting component 4.
[0032] Example 3:
[0033] Based on Embodiment 1, the connecting component 4 includes two frame-shaped frames 41 forming a V-shape. This V-shape prevents the accumulation of broken concrete and facilitates the installation of the mesh plate 43. A limiting opening is formed below the opposing surfaces of the two frame-shaped frames 41, allowing broken concrete to pass through easily. Another function of the V-shaped frame-shaped frames 41 is to block and intercept larger concrete blocks encasing metal impurities, and to prevent larger concrete supports from falling downwards when they are held in the limiting opening. Accordingly, a mesh plate 43 is fixedly connected to the inner side of each of the two frame-shaped frames 41. The mesh plate 43 facilitates the passage of broken concrete and prevents it from falling downwards if larger concrete blocks cause blockage in the limiting opening.
[0034] Reinforcing plates 44 are fixedly connected to the front and rear sides of the upper surfaces of the two frame frames 41. The reinforcing plates 44 are trapezoidal to facilitate the installation and fixation of the two frame frames 41. Strip blocks 42 are fixedly connected to the outer surfaces of the two frame frames 41 near the protective plate 54. The outer surfaces of the left and right strip blocks 42 are slidably connected to the inside of the sliding groove 55. A plate 45 is fixedly connected to the front side of the front reinforcing plate 44. The plate 45 provides a certain support when inserted into the box 1 and also facilitates the installation of the U-shaped handle.
[0035] A U-shaped handle is fixedly connected to the front side of the plate 45. The outer surface of the plate 45 slides through the outside of the box 1. When the concrete impurities and metal are separated, and there are a large amount of concrete encasing metal impurities in the limiting opening between the two frame frames 41, the plate 45, reinforcing plate 44 and frame frame 41 can be moved out by pulling the U-shaped handle, which facilitates the cleaning of the concrete blocking the limiting opening. After cleaning, the plate 45, reinforcing plate 44 and frame frame 41 can be put back in.
[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
