Description

Technical Field

[0001] The invention relates to the technical field of concrete waste treatment, in particular to a device for centralized collection and treatment of concrete waste. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion and mixed together to obtain cement concrete, also known as ordinary concrete. It is widely used in civil engineering and modern construction.

[0003] Construction or demolition will generate a large amount of concrete waste. Concrete waste is large in volume and difficult to degrade. Traditional landfill treatment methods are no longer sufficient to deal with it. Therefore, concrete needs to be recycled, such as as aggregate for recycled concrete. Recycled concrete refers to discarded concrete blocks that are crushed, cleaned, and graded, mixed in a certain proportion, and partially or completely replaced by natural aggregates such as sand and gravel (mainly coarse aggregate), and then added with cement, water, etc. to make new concrete.

[0004] The existing concrete waste treatment devices have a general dust removal effect during crushing. For example, the invention patent with publication number CN111468270B discloses a dust removal type concrete waste block crushing and recycling treatment device, which belongs to the field of concrete waste recycling technology, including a crushing box, a feed hopper is arranged in the middle of the upper surface of the crushing box, a first guide member is arranged at the top of the crushing box, a first crushing roller is arranged at the bottom of the first guide member, a second guide member is arranged below the first guide member, a filter screen is arranged above the second guide member, a second crushing roller is arranged above the filter screen, and a dust removal mechanism is arranged above the crushing box. However, when the treatment device is crushing, the dust generated by the crushing of the concrete inside it will always remain inside, and the dust-proof bag is only arranged at the material outlet end, and the dust removal effect is not significant.

A filter screen 9 is installed at the air inlet 8 by fastening bolts, so as to filter the circulating air. At the same time, the dust and impurities on the concrete waste can be driven by the flowing air. Moreover, since the air outlet 10 is arranged on the inner wall of the pretreatment box 1, the internal dust is prevented from leaking through the open end of the pretreatment box 1, so as to ensure the internal dust removal effect. The dust removal effect is good, and the negative pressure pump 11 arranged next to the air outlet 10 is used for stable The air circulates, and the circulating air will carry the dust and impurities generated in the crushing process and circulate together, and be discharged through the air outlet 10, and the dust and impurities in the circulating air will be filtered by the dust collecting bag, and the filtered air will be discharged, and the dust and impurities will be trapped in the dust collecting bag, so as to avoid the discharge of dust and the harm to the health of workers and the environment. The end of the guide plate 30 extends to the lower end of the air outlet 10, and the flow direction of the air is guided by the guide plate 30 to avoid the air extraction at the position of the air outlet 10, and at the same time, avoid the extraction of the crushed concrete clods in the pretreatment box 1, so as to cause the blockage of the air outlet 10. The dust collecting bag is movably installed in the plug-in slot 15 on the fixing seat 14, and because the dust collecting bag is arranged outside the pretreatment box 1 and the post-treatment box 2, it is convenient to disassemble. After long-term use, the dust collecting bag can be disassembled and conveniently replaced; The dust bag includes a plug-in board 31, a cloth bag 32, a movable plate 33 and a movable handle 34. The dust bag is a disposable consumable and can be directly replaced. When disassembling, first press the plug-in board 31 with one hand and pull the movable handle 34 upward with the other hand. The movable plate 33 moves upward, and the air inlet channel 1 35 and the air inlet channel 2 37 are misaligned. The movable plate 33 blocks the cloth bag 32 to prevent internal dust leakage. Then loosen the plug-in board 31 and pull out the plug-in board 31. The slider assembly 36 arranged on the side wall of the plate 33 serves to connect the plug-in plate 31 and the movable plate 33, and also serves as a limit to prevent the movable plate 33 from being directly and completely pulled out. During installation, a new dust bag can be directly inserted. When the movable plate 33 is pressed to the lower end, the air inlet channel 1 35 and the air inlet channel 2 37 are connected, and the dust filtering process is started. The dust bag is easy to replace. The plug-in plate 31, the movable plate 33 and the movable handle 34 are all made of plastic material, which reduces the cost of use.
