Description

Technical Field

[0001] The invention relates to the technical field of concrete waste treatment, and in particular to a device for treating precast concrete waste of highway bridge beams and slabs. Background Art

[0002] When prefabricated beams and slabs of highway bridges are prefabricated, they are usually prefabricated and processed at the bridge construction site or a large prefabrication site. A large amount of construction residues will be generated during the prefabrication process. Usually, when dealing with these residues, separate manpower and construction tools are required to handle them, which not only increases the production cycle of the beams and slabs, but also reduces the production efficiency of the beams and slabs, increases the production cost and wastes construction materials. The treatment of waste is usually carried out by a number of laborers using a manual cart or other equipment to transport the concrete residues to a designated location for simple treatment. This treatment method not only fails to keep the construction site clean and hygienic, but also invisibly increases the workload of the construction workers, resulting in a waste of manpower and resources.

[0021] Beneficial effects of the present invention:

[0022] (1) The waste is introduced into the feeding mechanism, diluted with water and stirred and crushed in the feeding mechanism, and then pumped into two separation barrels through the feeding mechanism. Then, the sand and gravel separation mechanism in the separation barrel fully separates the sand and gravel from the mud. At the same time, the separated mud can be automatically discharged and filtered during the separation process. After the separation is completed, the separated sand and gravel can be automatically discharged, thereby realizing the automatic separation and discharge of sand and gravel from mud in the waste, greatly improving the efficiency of waste treatment.

[0023] (2) The waste is pumped into the feed pipes on the two separation barrels through the feeding mechanism, and then the waste is impacted with the impact separation column and the two waste streams are offset through the two feed pipes to achieve impact separation of sand and gravel and mud. At the same time, the separation barrel is rotated to filter the waste through the filter ring plate under the action of centrifugal force. At the same time, the friction between the friction rod and the friction strip during filtration destroys the mud film wrapped on the surface of the waste, and then the mud film is separated from the sand and gravel under the action of centrifugal force, thereby achieving full separation of sand and gravel from mud in concrete waste and full recycling of sand and gravel in the waste.

[0024] (3) The separated mud flows down along the half-circle baffle plate, then enters the first guide plate with a certain slope, and then flows downward along the first guide plate. Then, it is blocked by the blocking block during the flow process to reduce the flow rate of the mud. At the same time, the mud is intercepted by the blocking strip on the blocking block, so that the mud is intercepted on the blocking block and the blocking strip, and the water in the mud flows out, thereby achieving a preliminary separation of mud and water in the mud and reducing the difficulty of subsequent mud separation treatment.

[0025] (4) When the mud is completely separated, the two mounting plates and the separation barrel are separated by the docking flipping mechanism, and the connecting plate is driven to rotate to tilt the separation barrel. At the same time, the second motor drives the second rotating shaft and the second guide plate to rotate so that the separation barrel rotates out of the mounting groove. At the same time, the first motor drives the first rotating shaft and the first guide plate to flip 180°. Then the separation barrel tilts to pour the separated sand and gravel onto the second guide plate, and then it is discharged through the second guide plate, thereby realizing automatic discharge of the separated sand and gravel.

[0046] The first transmission shaft 22 is driven to rotate by the first transmission motor 21, and the first transmission shaft 22 drives the separation barrel 3 to rotate through the first gear 23 and the second gear 24. At the same time, the first transmission shaft 22 drives the feed pipe 11 to rotate through the transmission wheel and the transmission belt.
