AI Technical Summary
In existing technologies, some particles of autoclaved aerated concrete block waste meet recycling requirements after initial crushing, but uniform secondary grinding increases recycling costs.
The primary crushing component is used for initial crushing, and larger particles are filtered by screening rods and guided to the secondary crushing component for secondary crushing through multiple screening rods, thus avoiding repeated crushing and improving crushing efficiency.
By combining screening and secondary crushing components, the repeated crushing of waste particles is avoided, thereby improving the crushing efficiency of waste recycling and reducing recycling costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waste recycling devices, and in particular to a waste recycling device for autoclaved aerated concrete blocks. Background Technology
[0002] Autoclaved aerated concrete (AAC) blocks, or simply AAC bricks, are AAC blocks produced using a high-temperature autoclaving process. AAC bricks are characterized by their light weight, good thermal insulation, strong earthquake resistance, good processing performance, certain high-temperature resistance, good sound insulation, and strong adaptability.
[0003] Chinese Patent CN216068031U discloses a waste recycling device for autoclaved aerated concrete (AAC) blocks, relating to the field of concrete block processing technology. The device includes a housing, inside which, from top to bottom, are arranged a crushing structure, a grinding structure, and a mixing structure. The grinding structure includes electrically driven push rods symmetrically arranged on both sides of the housing. This technical solution, through the grinding structure, uses a grinding plate to drive a rack in a reciprocating motion, appropriately grinding the already crushed AAC block waste. This ensures thorough crushing and grinding of the waste, reducing the risk of large particles and improving the quality of the recycled AAC.
[0004] However, the above-mentioned technical methods have the following shortcomings: after the waste is initially crushed, the particle size of some waste is already sufficient for waste recycling, and uniform secondary grinding can easily lead to an increase in waste recycling costs. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a waste recycling device that uses a primary crushing component to initially crush waste materials, filters the crushed waste materials through multiple screening rods, and further crushes larger waste materials through a secondary crushing component, thereby avoiding repeated crushing of waste particles and improving the crushing speed of waste materials.
[0006] The technical solution of this utility model is a waste recycling device for autoclaved aerated concrete blocks, comprising: a frame on which a primary crushing component is mounted; two movable frames detachably mounted on the frame, each movable frame being detachably mounted with a secondary crushing frame and a secondary crushing component; and a screening component comprising two base plates mounted side-by-side on the frame, multiple springs mounted on each of the two base plates, a screening frame mounted on the multiple springs, multiple screening rods mounted side-by-side on the screening frame, and a vibration generator mounted on the screening frame.
[0007] Preferably, the screening rod is inclined downward from the middle to both ends.
[0008] Preferably, the frame is provided with multiple inclined frames distributed in a ring.
[0009] Preferably, the primary crushing assembly includes a motor a mounted on a frame, crushing rollers a and b rotatably mounted on the frame, and a gear coaxially mounted on each of the crushing rollers a and b; the two gears are meshed together.
[0010] Preferably, the secondary crushing frame is provided with two relatively distributed inclined blocks, which are located below the secondary crushing component.
[0011] Preferably, the secondary crushing assembly includes a motor b mounted on a movable frame, and two secondary crushing rollers arranged side by side on the movable frame; the motor b is driven by the two secondary crushing rollers.
[0012] Compared with the prior art, the present invention has the following beneficial technical effects:
[0013] In use, the waste material is initially crushed by the primary crushing component into particles of different sizes. These particles fall onto multiple screening bars and are discharged from the bottom of the frame through the gaps between the bars. Particles that cannot pass through the screening bars move toward the two secondary crushing racks under the action of vibration and the screening bars, allowing them to be crushed a second time. This avoids repeated crushing of the particles required for waste recycling and improves the particle crushing efficiency of the waste. Attached Figure Description

Detailed Implementation
[0018] Example 1
[0019] like Figures 1-3As shown, the autoclaved aerated concrete block waste recycling device proposed in this embodiment includes a frame 1, a movable frame 2, and a screening assembly. The frame 1 is equipped with a primary crushing assembly. Two movable frames 2 are detachably mounted on the frame 1, and each of the two movable frames 2 is detachably equipped with a secondary crushing frame 8 and a secondary crushing assembly. The screening assembly includes two base plates 18 arranged side by side on the frame 1, multiple springs 12 arranged on each of the two base plates 18, a screening frame 9 arranged on the multiple springs 12, multiple screening rods 11 arranged side by side on the screening frame 9, and a vibration generator 10 arranged on the screening frame 9.
[0020] The screening rods 11 slope downwards from the middle to both ends. The waste material from the initial crushing falls onto multiple screening rods 11. Larger waste particles slide towards both ends of the screening rods 11 under the influence of vibration and their own gravity, while smaller waste particles fall through the gaps between the multiple screening rods 11, thus avoiding repeated processing of waste and increasing the processing speed. The frame 1 is equipped with multiple inclined frames 16 arranged in a ring. The frame 1 is also connected to a discharge pipe 17. The multiple inclined frames 16 are arranged in a ring around the discharge pipe 17, and waste particles fall from the multiple inclined frames 16 onto the discharge pipe 17 and flow out.
[0021] In this embodiment, the waste material is initially crushed by the primary crushing component, breaking it into particles of different sizes. The waste particles fall onto multiple screening rods 11 and are discharged from the bottom of the frame 1 through the gaps in the screening rods 11. The waste particles that cannot pass through will move toward the two secondary crushing frames 8 under the action of vibration and screening rods 11, so that the waste particles are crushed a second time through the secondary crushing frames 8, avoiding repeated crushing of the particles required for waste recycling and improving the particle crushing efficiency of the waste.
[0022] Example 2
[0023] like Figure 1 and Figure 2 As shown, the autoclaved aerated concrete block waste recycling device proposed in this embodiment, compared with the first embodiment, includes a preliminary crushing component including a motor a3 mounted on a frame 1, crushing rollers a4 and b5 rotatably mounted on the frame 1, and a gear 6 coaxially mounted on each of the crushing rollers a4 and b5; the two gears 6 are meshed with each other.
[0024] In this embodiment, motor a3 drives a single crushing roller a4 to rotate, and crushing roller a4 drives crushing roller b5 to rotate through two gears 6, so that crushing roller a4 and crushing roller b5 rotate relative to each other to crush waste. At the same time, the shadow area of crushing roller a4 and crushing roller b5 is smaller than the shadow area of screening frame 9, thereby preventing the waste crushed by the preliminary crushing component from falling outside the screening frame 9.
[0025] Example 3
[0026] like Figure 2 and Figure 3 As shown, this embodiment proposes a waste recycling device for autoclaved aerated concrete blocks. Compared to Embodiment 1, in this embodiment, two relatively distributed inclined blocks 15 are arranged on the secondary crushing frame 8, and the inclined blocks 15 are distributed below the secondary crushing component. The secondary crushing component includes a motor b7 arranged on the movable frame 2, and two secondary crushing rollers 14 arranged side by side on the movable frame 2; the motor b7 is driven by the two secondary crushing rollers 14.
[0027] In this embodiment, the waste particles falling into the secondary crushing frame 8 are crushed by the two secondary crushing rollers 14, reducing the size of the waste particles. Then, the waste particles fall onto the inclined block 15, which guides the waste back into the frame 1. The screening frame 9 extends into the secondary crushing frame 8, allowing the waste particles to fall directly between the two secondary crushing rollers 14, reducing the probability of waste falling between the secondary crushing rollers 14 and the secondary crushing frame 8, and reducing the amount of waste accumulating inside the secondary crushing frame 8.
[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
