Description

Technical Field

[0001] The invention relates to the technical field of construction waste recycling, in particular to a shaping machine and a process thereof for recycled aggregates of construction waste. Background Art

[0002] Recycled aggregate from construction waste is the aggregate with a nominal particle size of less than 40 mm obtained from the demolition of buildings (structures), road renovation, concrete production, engineering construction and other situations. The conversion rate of construction waste to aggregate can reach 85%, that is, 1 ton of construction waste can produce 0.85 tons of recycled aggregate, and the price is much cheaper than natural aggregate. However, some investors are skeptical about the performance of recycled aggregate. We record the aggregate produced by the general process as recycled aggregate 1, pass recycled aggregate 1 through a 5mm vibrating screen to remove fine particles such as cement and mortar, and finally obtain recycled aggregate 2. Next, we will analyze the difference between the two in terms of particle size, impurity content, density, water absorption, crushing value and firmness.

[0003] The sand and gravel in concrete are called aggregates, which play the role of skeleton. Recycled aggregates have many edges and corners, rough surfaces and cement mortar that has not fallen off. If they are not cleaned, it will affect the quality of the aggregates. In addition, the existing aggregates are screened in an open-air environment and produce a lot of dust, which pollutes the environment in the air and affects people's production and life. However, during the use of the existing construction waste recycled aggregate shaping machine, the aggregate shaping machine relies on manual or mechanical arms to separate the plastic, foam, wood, foam, metal and aggregate of the construction waste, which is costly and causes certain economic losses.

3. A shaping machine process for recycled aggregate from construction waste, characterized in that: The specific steps include: S1, firstly, the crushed aggregate is poured in from the first feed port (16), and the aggregate enters the interior of the cylinder (15) through the first feed port (16). The construction waste entering the interior of the cylinder (15) is accumulated at the upper end of the cylinder (15). At this time, the first motor (21) is started to rotate. The rotation of the first motor (21) drives the first rotating shaft (22) to rotate. The rotation of the first rotating shaft (22) drives the first scraper (23) to rotate. The rotation of the first scraper (23) drives the construction waste to rotate relatively slowly around the cylinder (15). In the process of the first scraper (23) driving the construction waste to rotate around the cylinder (15), the metal material will be attracted to the bottom end of the fixed plate (26) by the magnet (27); S2, when the first scraper (23) drives the construction waste to rotate in the drum to the first opening (24), the construction waste will fall from the first opening (24), and at the same time, the first scraper (23) continues to drive the metal adsorbed by the magnet (27) at the bottom of the fixed plate (26) to rotate around the drum (15). When the first scraper (23) drives the metal adsorbed by the magnet (27) at the bottom of the fixed plate (26) to rotate to the second opening (25), since there is no magnet at the upper end of the second opening (25), the metal at the bottom of the fixed plate (26) will fall from the second opening (25), and the metal falling to the second opening (25) will be discharged from the equipment through the discharge chute (28); S3, the construction waste falling from the first opening (24) falls into the interior of the outer shell (11), the interior of the outer shell (11) is filled with water, and the crushed construction waste falls into the interior of the second feed opening (17), at which time the foam, plastic bags, wood, and plastic in the construction waste float on the water surface, while the concrete block construction aggregate falls to the bottom of the water; S4, the first rotating shaft (22) rotates and drives the second scraper (31) to rotate at the same time. When the second scraper (31) rotates, the foam, plastic bags, wood, and plastic floating on the water surface are cleaned into the collection bucket (110) in cooperation with the arc shape of the baffle (13). Concrete blocks and building aggregates that fall to the bottom of the water enter the roller (56), which is placed obliquely inside the housing (11); S5, the first rotating shaft (22) rotates to drive the first bevel gear (41), the first bevel gear (41) rotates to drive the second bevel gear (42), the second bevel gear (42) rotates to drive the universal joint (43), the universal joint (43) rotates to drive the second rotating shaft (45), the second rotating shaft (45) rotates to drive the screw rod (46), the screw rod (46) rotates to drive the building aggregate to be transported upward from the bottom end of the housing (11); S6, during the rotation of the spiral rod (46), the flap (59) is driven to flip and clean the building aggregate inside the roller (56), so that the mud and sand on the surface of the aggregate are cleaned, thereby improving the production quality of the aggregate. At the same time, a second small hole (510) is opened on the spiral rod (46), so that when the building aggregate is pushed upward, water will flow back to the inside of the housing (11) through the second small hole (510), and when the spiral rod (46) drives the building aggregate to move upward, the mud and sand will fall from the first small hole (57) to the upper end of the bottom plate (19); S7, when the second rotating shaft (45) rotates, the first spur gear (51) is driven to rotate, the rotation of the first spur gear (51) drives the second spur gear (52) to rotate, the rotation of the second spur gear (52) drives the rack (53) to rotate, the rotation of the rack (53) drives the roller (56) to rotate, the rotation of the roller (56) drives the outer spiral (58) to rotate, the rotation of the outer spiral (58) drives the mud and sand on the bottom plate to be cleaned out of the device, and the construction aggregate is pushed out of the device from the inside of the roller (56) by the screw rod (46).
