Description

A device for processing recycled waste concrete

Technical Field

The invention relates to the field of concrete recycling, crushing and utilization, and in particular to a waste concrete recycled material processing device.

Background technique

After the dismantling of the building, the discarded concrete blocks can be used to replace gravel to produce dozens of environmentally friendly bricks such as lawn bricks, square bricks, blind hole bricks, permeable bricks, partition bricks, modular bricks, insulation bricks and block bricks after reasonable crushing, screening and grinding, which have very high recycling value.

The most commonly used concrete crushing device is a hammer crusher, which can effectively break concrete into smaller pieces through the strong impact force exerted by the hammer. These pieces can be further processed into reusable materials for new construction projects or road repair projects.

A hammer crusher for ore crushing disclosed in Chinese patent publication number CN117399118A includes a rotating shaft II, one end of which is fixedly mounted with a driving pulley by bolt connection, a mounting plate is fixedly mounted on the outer surface of the rotating shaft II by welding, the mounting plates are distributed in a ring array, a clamping plate is fixedly mounted on one side of the mounting plate by welding, and a push piece is fixedly mounted between the mounting plate and the clamping plate by clamping.

However, compared with the existing technologies in related fields, due to the different sizes of waste concrete, during the process of adding materials to crush, larger pieces of rock may be stuck between the pusher and the crushing chamber, and slide at the bottom of the crushing chamber as the pusher pushes. When they slide to the mesh of the screen, they may be stuck in the mesh of the screen under the thrust of the pusher, causing blockage and affecting material falling.

A pulley 9 is fixedly installed at one end of the rotating shaft 2. When in use, a motor is installed on one side of the side lining 102, and then another driving pulley is installed at the output end of the motor. The driving pulley is then connected to the pulley 9 through a belt. At this time, the motor can be used to control the rotation of the pulley 9 (the motor and belt transmission structure are well-known technologies in this technical field, so their specific structure and working principle are not described).

As shown in Figures 6 and 13, the trigger assembly 6 includes a movable rod 601 that is axially slidably and circumferentially rotated with the partition 3.

The protrusions 802 inside the two fixed covers 801 are staggered. The ball bearings 603 of the movable rod 601 cooperate with the plurality of protrusions 802 to cause the second hammer member 5 to slide back and forth between two adjacent first hammer members 4 (as shown in Figures 6 to 7). The reciprocating sliding of the second hammer member 5 can crush the concrete blocks, thereby ensuring the crushing effect and crushing efficiency. A plurality of first fixed shafts 803 are fixedly provided on the side, and a second fixed shaft 804 is fixedly provided between two adjacent first fixed shafts 803 of the fixed cover 801. A plurality of second fixed shafts 804 are arranged on one side close to the axis of the fixed cover 801. A plurality of first fixed shafts 803 and a plurality of second fixed shafts 804 are combined to form a wavy track. By utilizing the movable rod 601 to cooperate with the plurality of first fixed shafts 803 and the plurality of second fixed shafts 804, the movable rod 601 can drive the first hammer 4 and the second hammer 5 to slide back and forth up and down (as shown in Figures 4 and 5), and cooperate with the support rod 701 to smash the non-standard materials, prevent the non-standard materials from being accumulated on the filter screen for a long time, and ensure the feeding efficiency.

The working process is as follows:

S1, as shown in FIG3 and FIG13, the partition plate 3 is driven to rotate by the rotating shaft 2, and then the partition plate 3 drives the trigger component 6 to rotate synchronously;

S2, as shown in Figures 3, 6, 7, 8, 12 and 13, when the first hammer 4 and the second hammer 5 arrive at one side of the feed port, the ball 603 of the movable rod 601 cooperates with the plurality of protrusions 802, causing the second hammer 5 to slide back and forth between two adjacent first hammers 4. The reciprocating sliding of the second hammer 5 can crush the concrete blocks, thereby ensuring the crushing effect and efficiency.

S3, as shown in Figures 3, 4, 5, 12 and 13, when the first hammer 4 and the second hammer 5 reach one side of the screening mechanism, the movable rod 601 cooperates with the first fixed shafts 803 and the second fixed shafts 804, so that the movable rod 601 drives the first hammer 4 and the second hammer 5 to slide up and down, and cooperates with the support rod 701 to smash the non-standard materials, prevent the non-standard materials from being accumulated at the filter screen for a long time, and ensure the feeding efficiency;

S4, as shown in FIGS. 9 to 14, when the second hammer 5 encounters a concrete block alone, the second hammer 5 drives the movable rod 601 to flip backwards, and then when the second hammer 5 swings, the concrete block contacts the side of the second hammer 5, and then the concrete block rotates, thereby utilizing the rotation to improve the collision effect between the concrete block and the counterattack plate 103;

S5. As shown in FIG. 3 , the first hammer 4 and the second hammer 5 can be used to smash the concrete block toward the impact plate 103 , and then the collision between the concrete block and the impact plate 103 can improve the crushing effect.
