Description

Technical Field

[0001] The utility model relates to the technical field of construction waste treatment, in particular to a construction waste crushed material impurity removal and adsorption device provided with a screening mechanism. Background Art

[0002] With the advancement of house erection technology, more and more houses are built with frames and steel structures. As the service life of houses is reached, they are demolished within a limited period of time, which will generate a large amount of construction waste. Construction waste refers to the slag, waste and other wastes generated by construction, construction units or individuals in the process of construction, laying or demolition and repair of various buildings. With the continuous planning and development of cities, reinforced concrete buildings will be demolished and newly built, resulting in a large amount of construction waste. The treatment, recycling and reuse of construction waste is the best way to deal with construction waste. However, after the construction waste is crushed, many rusty iron products such as steel bars, screws, iron wires, etc. will be mixed in the construction waste fragments. If these iron products are mixed with recycled materials and used again, the rust will cause the wall or the inside of the ground to expand and affect the quality, and it will also waste iron resources.

The scrap iron is gathered and scraped off through the inclined design of the dividing and cutting blocks, thereby removing the scrap iron from the construction waste fragments and reducing the impact of the scrap iron swelling due to moisture when the fragments are used later.

[0016] 1.

Then the magnet located above the frame will absorb the scrap iron in the construction waste fragments. When the screening is completed, the push cylinder can be started to make the magnet slide along the direction of the sliding block. The sliding block makes the magnet move more stably, allowing the material dividing block to scrape off the scrap iron on the outer surface of the magnet, remove the scrap iron contained in the construction waste fragments, and reduce the impact of the scrap iron when the construction waste fragments are used later;

[0017] 2. The rotation of the driving motor will drive the cam to rotate. When the cam rotates to the lowest point, it will push the contact block to drive the frame to rise.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 The utility model provides a technical solution: a construction waste debris impurity removal and adsorption device with a screening mechanism, comprising a frame 1, a feed port 2 is fixedly installed on the side surface of one end of the frame 1, and a conveyor belt 3 is fixedly installed inside the feed port 2, a discharge port 4 is fixedly arranged on the end of the frame 1 away from the feed port 2, and the discharge port 4 is lower than the height of the feed port 2, and the feed port 2 is inclined in design, the interior of the frame 1 is divided into two sections, and a push cylinder 7 is fixedly installed on the outer surface of one end of the frame 1, and a drive motor 8 is fixedly installed on the side surface of the frame 1, and a screening mechanism is arranged between the frame 1 and the push cylinder 7, through which the iron in the crushed construction waste debris is directly adsorbed and collected.

[0028] The crushed construction waste fragments are transported by the conveyor belt 3, so that the construction waste fragments enter the interior of the frame 1 through the feed port 2. The inclined design of the feed port 2 can make the excess construction waste fragments fall into the interior of the frame 13. The feed port 2 is higher than the position of the feed port 2, so that the screened construction waste fragments can be discharged from the frame 1 more easily.

[0029] The screening mechanism includes: a magnet 5, which is installed through the outer surface of the frame 1, and one end of the frame 1 is engaged with the magnet 5, and the magnet 5 and the frame 1 are slidably connected, a sliding block 6 is fixedly installed on the outer surface of the magnet 5, and the sliding block 6 is slidably installed inside the frame 1, and the frame 1 is engaged with the sliding block 6, a material dividing block 16 is fixedly installed inside the frame 1, and the material dividing block 16 is a triangular inclined design, and the outer surface of the material dividing block 16 is in contact with the outer surface of the magnet 5, and the output end of the push cylinder 7 is connected to the magnet 5.

[0030] When the construction waste fragments enter the interior of the frame 13, the magnet 5 will absorb the scrap iron in the fragments. When the absorption is completed, the pushing cylinder 7 can be started. By extending the pushing cylinder 7, the magnet 5 can slide inside the frame 1, and the magnet 5 can move along the direction of the sliding block 6. At the same time, the limit of the sliding block 6 can make the movement of the magnet 5 more stable, so that the magnet 5 can contact the dividing and cutting block 16 with the absorbed scrap iron, and the scrap iron can be scraped off through the inclined design of the dividing and cutting block 16 to remove the scrap iron in the construction waste fragments, so that the subsequent use will not be affected by the scrap iron.

[0031] A frame 13 is provided inside the frame 1, and a rotating shaft 12 is fixedly installed on the side surfaces of both ends of the frame 13, the outer surface of the rotating shaft 12 passes through the outer surface of the frame 1, and the frame 1 is rotatably connected to the rotating shaft 12, a spring 11 is fixedly installed on one end of the frame 13 away from the rotating shaft 12, and one end of the spring 11 is connected to the frame 1, a prismatic step block 14 is fixedly installed on the inner side of the frame 13, and the prismatic step block 14 is washboard-shaped, and one end of the frame 13 is located above the discharge port 4.

[0032] After the material is transported to the interior of the frame 13 by the conveyor belt 3, the frame 13 vibrates so that the material moves along the direction of the prismatic step block 14, causing the material to roll and move inside the frame 13. The movement and rolling allow the scrap iron in the construction waste to follow the movement, allowing the scrap iron to be more easily adsorbed by the magnet 5.

[0033] A transmission mechanism is provided on the outer surface of the frame 13, and the frame 13 is driven to vibrate by the transmission mechanism, so that the construction waste entering the inside of the frame 1 is turned over and vibrated, so that the scrap iron in the waste can be vibrated out, which is convenient for the magnet 5 to adsorb.

[0034] When the construction waste fragments enter the interior of the frame 13, the rotation of the driving motor 8 will drive the cam 9 to rotate, so that the cam 9 reaches the lowest point as it rotates, and then pushes the frame 13 to move up. Then, when the cam 9 rotates to the highest point, the spring 11 will push the frame 13 back, and the contact block 10 can expand the force-bearing area of ​​the cam 9 and the solid frame 13, so that the solid frame 13 is not easily deformed when the cam 9 and the contact block 10 are running and rotating. At the same time, when the cam 9 and the contact block 10 are worn out after long-term use, the cam 9 and the cam 9 can be replaced, so that the frame 13 can vibrate up and down with the rotating shaft 12 as the center of the circle, so that the entered construction waste fragments can move along the prismatic step block 14, and the prismatic step block 14 can make the construction waste fragments flip and roll, so that large pieces of construction waste fragments can roll through the prismatic step block 14 and be discharged from the discharge port 4, and the irregularly shaped materials will stay and flip and roll slowly with the vibration, so that large pieces of construction waste can pass quickly and the scrap iron can also be quickly turned out and adsorbed by the magnet 5.

[0035] A lower hopper 15 is fixedly installed on the outer surface of one end of the frame 1 close to the pushing cylinder 7, and the interior of the lower hopper 15 is designed to be inclined, and a material presentation frame 17 is placed below the lower hopper 15, and a handle is fixedly installed on the side surface of the material presentation frame 17, and a roller is provided on the outer surface of the material presentation frame 17, and the side surface of the material presentation frame 17 is in contact with the outer surface of the frame 1.

After the screening is completed, the material presentation frame 17 can be moved by the handle to conveniently move the scrap iron in the material presentation frame 17 to the recycling area for centralized processing.
