Description

Technical Field

[0001] This utility model relates to the field of construction waste recycling, and more specifically, it relates to a green construction waste recycling dust prevention device. Background Technology

[0002] Construction projects often generate a large amount of construction waste, especially large concrete blocks. When recycling these large concrete blocks, it is generally necessary to first crush them into smaller pieces to facilitate recycling and transportation. However, existing concrete crushing and recycling equipment often generates a large amount of concrete powder during the crushing process, causing dust pollution and hindering the green recycling of construction waste. Furthermore, after crushing the concrete, a large amount of dust adheres to the crushed concrete blocks. When transferring or transporting these blocks, the dust adhering to the concrete blocks is often stirred up, affecting the transfer of the concrete blocks and causing environmental pollution.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a green construction waste recycling dust prevention device, which has the following beneficial effects:

[0017] 1. This utility model, by setting up a dust suppression structure, allows for the crushing of larger concrete blocks into smaller ones. The concrete blocks are added to the crushing box, and a motor drives the crushing rollers to rotate, crushing the concrete blocks. During this crushing process, a large amount of dust is generated. An external water pump installed in the first water tank pumps water through the first connecting pipe into the intermediate block, from which it is sprayed out from the first nozzle. This water absorbs the dust, causing it to fall into the cleaning box, thus reducing the dust generated during the concrete block crushing process and protecting the environment.

[0018] 2. This utility model, by setting up a cleaning structure, allows water to be pumped into the mounting block through the second connecting pipe after the broken concrete blocks enter the cleaning box via an external water pump in the second water tank. The water is then sprayed out from the second nozzle to wash away the powder and dust adsorbed on the broken concrete blocks, reducing the amount of powder on the broken concrete blocks. The broken concrete blocks then roll off the guide platform and are discharged through the outlet on the cleaning box, thus completing the cleaning of small concrete blocks and facilitating their transfer and transportation.

[0019] 3. This utility model incorporates a collection box. During the washing process, water that has absorbed powder passes through a water passage on the guide platform and enters the collection box. After collection, the collection box is heated by a heating wire at the bottom of the cleaning box to evaporate the water and collect the powder clumps inside. By rotating the locking block, the collection box can be pulled out of the box, thus facilitating the collection of powder and dust generated during crushing. Attached Figure Description

[0031] In this embodiment, large pieces of concrete are crushed by the crushing box 2, and the dust-reducing structure reduces the dispersion of dust.

[0032] More specifically, the cleaning structure facilitates the removal of powder adhering to the concrete blocks.

[0033] Please see Figures 1-5As one implementation method for crushing concrete blocks: the crushing roller 3 is rotatably connected to the crushing box 2, the outside of the crushing box 2 is fixedly equipped with a motor 13, the output end of the motor 13 is fixedly connected to the crushing roller 3, the first water tank 5 is fixedly equipped on the extension frame 4, the intermediate block 6 is fixedly equipped on the extension frame 4, the intermediate block 6 is hollow inside, multiple first nozzles 7 are provided, the first nozzles 7 are fixedly equipped on the intermediate block 6, the first nozzles 7 are connected to the intermediate block 6, the first connecting pipe 14 is provided between the first water tank 5 and the intermediate block 6, the first water tank 5 and the intermediate block 6 are connected through the first connecting pipe 14, and multiple first connecting pipes 14 are provided;

[0034] Specifically, when crushing concrete blocks, the concrete blocks are added to the crushing box 2, and the crushing roller 3 is driven by the motor 13 to rotate and crush the concrete blocks. During the crushing process of the crushing roller 3, a large amount of dust is generated. The water is pumped into the intermediate block 6 through the first connecting pipe 14 by an external water pump installed in the first water tank 5, and sprayed out from the first nozzle 7. The water absorbs the dust and causes the dust to fall into the cleaning box 1.

A second nozzle 12 is fixedly mounted on the installation block 11 and communicates with the installation block 11. A second connecting pipe 15 is provided between the installation block 11 and the second water tank 10. A support block 16 is fixedly mounted inside the cleaning box 1. A guide platform 17 is detachably mounted inside the cleaning box 1. The guide platform 17 has water passage holes 18 for guiding materials.

The crushed concrete blocks roll off the guide platform 17 and are discharged through the discharge port 20 on the cleaning box 1. The water that has absorbed the powder during the cleaning process passes through the water passage 18 on the guide platform and enters the collection box 9. After collection, the collection box 9 is heated by the heating wire 22 at the lower end of the cleaning box 1 to evaporate the water and collect the powder agglomerates in the collection box 9. The locking block 23 is rotated to pull the collection box 9 out of the collection box 9, thus realizing the collection of powder and dust generated by crushing.

[0037] In summary, when using it as a whole:

[0038] When crushing concrete blocks, the concrete blocks are added to the crushing box 2. The crushing roller 3 is driven by the motor 13 to rotate and crush the concrete blocks. During the crushing process of the crushing roller 3, a large amount of dust is generated. The water is pumped into the intermediate block 6 through the first connecting pipe 14 by the external water pump installed in the first water tank 5. The water is then sprayed out from the first nozzle 7, thereby absorbing the dust and causing the dust to fall into the cleaning box 1.

[0039] When the crushed concrete blocks enter the cleaning box 1, water is pumped into the mounting block 11 through the second connecting pipe 15 by an external water pump in the second water tank 10. The water is then sprayed out from the second nozzle 12 to wash away the powder and dust adsorbed on the crushed concrete blocks, reducing the amount of powder on the crushed concrete blocks. The crushed concrete blocks roll off the guide platform 17 and are discharged through the discharge port 20 on the cleaning box 1. The water that has absorbed the powder during the cleaning process passes through the water passage 18 on the guide platform and enters the collection box 9. After collection, the collection box 9 is heated by the heating wire 22 at the lower end of the cleaning box 1 to evaporate the water and collect the powder agglomerates in the collection box 9. The locking block 23 is rotated to pull the collection box 9 out of the collection box 9, thus realizing the collection of powder and dust generated by crushing.
