Description

Technical Field

[0001] This utility model relates to the field of aerated concrete block production technology, and in particular to an aerated concrete block edge material crushing device. Background Art

[0002] Existing aerated concrete block waste crushing equipment uses a crushing roller that rotates in one position to crush the aerated concrete block waste. When the aerated concrete block waste collides with the crushing roller, the crushing roller squeezes the aerated concrete block waste and splashes it away, causing the aerated concrete block waste to be not around the crushing roller, resulting in ineffective crushing and inconvenience in use.

[0003] Chinese patent CN218742264U discloses a crushing device for aerated concrete block waste, including two support frames. A crushing frame is fixedly installed between opposite sides of the two support frames, and a fixing frame is fixedly installed on the top of the crushing frame. This aerated concrete block waste crushing device, through its crushing mechanism, allows the crushing roller and crushing cone to rotate at various positions within the crushing frame instead of rotating in a single position, effectively crushing the aerated concrete block waste and ensuring comprehensive crushing. By setting up a receiving box and mounting screws, after the aerated concrete block waste is crushed, the mounting screws are loosened to remove the receiving box, where the crushed aerated concrete block waste is collected, thus solving the problem of incomplete crushing.

[0004] However, in practical applications, it has been found that when crushing waste concrete, crushing devices with larger crushing cones can quickly decompose the concrete, but the decomposed concrete particles are larger. While crushing devices with smaller crushing cones can crush the concrete more thoroughly, they have the problems of slower decomposition speed and larger concrete particles that can easily damage the smaller crushing cone. At the same time, when feeding waste concrete, concrete blocks are prone to bridging, which can cause the feed inlet to be blocked by concrete and prevent the material from being fed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a crushing device for aerated concrete block edge material. By setting the crushing mechanism in stages, materials of different volumes are crushed separately, avoiding the problem of damage to the crushing equipment in the prior art, while also taking into account the crushing effect and smooth material feeding.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A device for crushing edge material of aerated concrete blocks includes a feeding assembly, a first crushing box located below the feeding assembly, and a second crushing box located at the end of the feeding assembly. A receiving box is connected to the bottom of the first crushing box. The feeding assembly includes a feeding hopper, and a linear vibrating screen is located below the feeding hopper. The linear vibrating screen includes a first discharge port corresponding to the first crushing box and a second discharge port corresponding to the second crushing box. The first crushing box contains a secondary crushing assembly and a tertiary crushing assembly arranged from top to bottom. The second crushing box contains a primary crushing assembly. A discharge pipe is located at the bottom of the second crushing box, and the end of the discharge pipe is connected to the first crushing box.

[0008] Furthermore, the second crushing chamber between the second-stage crushing component and the third-stage crushing component is provided with a material guide hole on its wall, and the end of the discharge pipe is fixedly installed through the material guide hole.

[0009] Furthermore, the linear vibrating screen includes a support frame and a screen box mounted on the support frame. The screen box is equipped with a screen mesh inside. A vibrating motor is connected to the bottom of the screen box. A shock-absorbing spring is provided between the screen box and the support frame. One end of the screen box is connected to the feed hopper, and the other end of the screen box is connected to the corresponding first discharge port and second discharge port respectively.

[0010] Furthermore, the conveying angle of the linear vibrating screen is 5 to 15° with respect to the horizontal plane.

[0011] Furthermore, the primary crushing assembly includes two sets of roller crushing assemblies arranged vertically, each set of roller crushing assemblies including a secondary toothed roller and a main toothed roller, and each set of roller crushing assemblies is equipped with a drive motor.

[0012] The beneficial effects of this utility model are:

[0013] In practical applications, a linear vibrating screen is used for graded feeding, separating the edge material of the aerated concrete blocks according to their volume. The sieved edge material is then fed into the corresponding first and second crushing chambers. This solves the problem in existing technologies where waste concrete blocks easily bridge during feeding, causing blockages at the inlet and preventing material from flowing. The first crushing chamber contains secondary and tertiary crushing components for two-stage crushing of small-volume edge material. The secondary and tertiary crushing components can utilize existing crushing structures. The second crushing chamber initially crushes the larger-volume edge material, which is then fed back into the first crushing chamber through a discharge pipe for further crushing. This distributes the crushing pressure across individual crushing components, making the crushing process more targeted and effectively preventing the problem in existing technologies where larger concrete blocks can directly damage smaller crushing cones. This crushing device, through its graded crushing mechanism, crushes materials of different volumes separately, avoiding damage to the crushing equipment in existing technologies, while also ensuring both crushing effectiveness and smooth material flow.

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0018] like Figure 1-3 As shown, this utility model provides a crushing device for aerated concrete block edge material, including a feeding assembly 1, a first crushing box 2 below the feeding assembly 1, a second crushing box 3 at the end of the feeding assembly 1, and a receiving box 4 connected to the bottom of the first crushing box 2; the feeding assembly 1 includes a feeding hopper 11, a linear vibrating screen 12 below the feeding hopper 11, the linear vibrating screen 12 including a first discharge port 13 corresponding to the first crushing box 2 and a second discharge port 14 corresponding to the second crushing box 3; the first crushing box 2 is provided with a secondary crushing assembly 21 and a tertiary crushing assembly 22 from top to bottom, the second crushing box 3 is provided with a primary crushing assembly 31, and the bottom of the second crushing box 3 is provided with a discharge pipe 32, the end of the discharge pipe 32 being connected to the first crushing box 2.

[0019] In this embodiment, a linear vibrating screen 12 is used for graded feeding, screening the edge material of the aerated concrete block according to its volume. The screened edge material is then fed into the corresponding first crushing box 2 and second crushing box 3. This solves the problem in the prior art where concrete blocks easily bridge during feeding, causing the feed inlet to be blocked and unable to discharge. The second-stage crushing component 21 and the third-stage crushing component 22 in the first crushing box 2 perform two-stage crushing of small-volume edge material. The second-stage crushing component 21 and the third-stage crushing component 22 can use existing crushing structures. The second crushing box 3 performs preliminary crushing of large-volume edge material and then feeds it back into the first crushing box 2 through the discharge pipe 32 for further crushing. This distributes the crushing pressure of a single crushing component, making the crushing process more targeted and effectively avoiding the problem in the prior art where larger concrete blocks can easily damage smaller crushing cones. This crushing device, by setting up a graded crushing mechanism, crushes materials of different volumes separately, avoiding the problem of damage to crushing equipment in the prior art, while also ensuring crushing effect and smooth material discharge.

[0020] like Figure 2 As shown, the second crushing box 2 between the second-stage crushing component 21 and the third-stage crushing component 22 has a guide hole 23 on its box wall, and the end of the discharge pipe 32 is fixedly installed in the guide hole 23. In this embodiment, the material crushed by the second crushing box 2 is fed into the third-stage crushing component 22 in the first crushing box 2. The third-stage crushing component 22 is used to perform secondary crushing on the material after the first-stage and second-stage crushing, so that the crushing effect is better. The material after the first-stage crushing does not need to pass through the second-stage crushing component 22, which reduces the working pressure of the second-stage crushing component 22 and effectively extends the service life of the equipment.

[0021] like Figure 1 and Figure 3 As shown, the linear vibrating screen 12 includes a support 121 and a screen box 122 mounted on the support 121. A screen mesh 123 is provided inside the screen box 122. A vibrating motor 124 is connected to the bottom of the screen box 122. A shock-absorbing spring 125 is provided between the screen box 122 and the support 121. One end of the screen box 122 is connected to the feed hopper 11, and the other end is connected to the corresponding first discharge port 13 and second discharge port 14. In this embodiment, the linear vibrating screen 12 uses the vibrating motor 124 as the vibration source, causing the material to be thrown up on the screen mesh 123 and move forward in a straight line. Several specifications of oversize and undersize materials are generated through the screen mesh and discharged from their respective outlets. It features low energy consumption, high output, simple structure, easy maintenance, a fully enclosed structure, no dust spillage, and automatic material discharge, making it more suitable for assembly line operations.

[0022] like Figure 1As shown, the conveying angle of the linear vibrating screen 12 and the inclination angle of the horizontal plane are 5 to 15°. In this embodiment, considering that the edge material of the aerated block has an irregular shape and some sharp edges, in order to make the feeding process smoother, the conveying part of the linear vibrating screen 12 is set at a certain angle and gravity is used to assist the conveying. After testing, it was found that the feeding is stable and efficient when the inclination angle is 5 to 15°.

[0023] like Figure 1 As shown, the primary crushing component 31 includes two sets of roller crushing components arranged vertically. Each set of roller crushing components includes a secondary toothed roller and a primary toothed roller, and each set of roller crushing components is equipped with a drive motor. In this embodiment, the primary crushing component is designed with two sets of roller crushing components. The spacing and specifications of the crushing teeth of the secondary toothed roller and the primary toothed roller of the upper roller crushing component are larger than those of the secondary toothed roller and the primary toothed roller of the lower roller crushing component, so as to crush the material as much as possible.

[0024] All technical features in this embodiment can be modified in appearance according to actual needs.

[0025] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
