Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer separation, in particular to a separation device for recycling production waste. Background Art

[0002] Industrial waste refers to solid, semi-solid, liquid and gaseous items and materials in containers that have lost their original value or have not lost their value but have been abandoned or discarded during industrial production activities. After industrial waste is generated, it must be piled up on land. The larger the amount of accumulation, the more land it occupies. When waste is piled up, the harmful components in it are easy to pollute the land. When pathogenic microorganisms and other harmful substances in the contaminated soil enter the water body with natural precipitation, runoff or seepage, they may further endanger human health. Large amounts of industrial solid waste discharged into rivers, lakes and seas will cause siltation, thereby blocking rivers, eroding farmland and endangering water conservancy projects. Toxic and harmful solid waste entering the water body will turn certain waters into biological dead zones. In order to treat industrial waste harmlessness, solid waste is treated through engineering to achieve the purpose of not harming human health and not polluting the surrounding natural environment.

[0003] A Chinese patent with publication number CN210045351U discloses an industrial solid waste separation and recovery device, including a bottom plate, two groups of support rods are symmetrically fixedly connected to one side of the bottom plate, the tops of the two groups of support rods are fixedly connected to a feeding bin, the discharge port opened on the feeding bin is connected to a crushing box, two groups of rotating shafts are rotatably connected in the crushing box, and crushing knives are fixedly connected to the two groups of rotating shafts. Two groups of reduction motors are fixedly installed on one side of the crushing box, and the output shafts of the two groups of reduction motors pass through the side wall of the crushing box and are respectively connected to one end of the two groups of rotating shafts through couplings.

The front of the collection box 7 is fixedly connected to the back of the cabinet 1, the two ends of the partition plate 701 are fixedly connected to the two sides of the inner wall of the collection box 7, one end of the dust suction pipe 1 702 is fixedly connected to the top of the collection box 7, and the other end of the suction pipe 1 is arranged above the feed bin 2. The box door 703 is hinged to the back of the collection box 7 by a hinge, and one end of the dust suction pipe 2 704 is fixedly connected to the back of the collection box 7. Connected to the bottom of the collecting box 7, the other end of the dust suction pipe 2 704 passes through the back of the cabinet 1 and extends inward, the air suction pump 1 705 and the air suction pump are respectively fixedly connected to the upper and lower left sides of the partition plate 701, and the protective cover 1 706 and the protective cover 2 708 are respectively arranged on the outside of the air suction pump 1 705 and the air suction pump 2 707. The dust suction pipe 1 702 and the dust suction pipe 2 704, through the action of the air suction pump 1 705 and the air suction pump 2 707, respectively absorb the dust generated during the crushing and falling process of the feed silo 2 and the cabinet 1 to prevent the dust of the waste from scattering and flying.

[0034] The screening device includes a discharge port 102, a feed plate 4, a support block 1 501, a support block 2 502, a spring 503, a screening plate 504, a baffle 505, a fixing plate 506, a motor 507, a connecting strip 508 and a protrusion 509. The discharge port 102 is opened on the left side of the cabinet 1, the feed plate 4 is fixedly connected to the outside of the discharge port 102, the support block 1 501 and the support block 2 502 are respectively fixedly connected to the two sides inside the cabinet 1, the bottom of the spring 503 is fixedly connected to the upper surface of the support block 1 501 and the support block 2 502, there are two groups of springs 503, each group has two, and the bottoms thereof are respectively arranged on the front and back sides of the upper surface of the support block 1 501 and the support block 2 502. The top of the spring 503 is fixedly connected to the lower surface of the screening plate 504, the two baffles 505 are fixedly connected to the front and rear sides of the screening plate 504, the left side of the fixed plate 506 is fixedly connected to the right side of the cabinet 1, the bottom of the motor 507 is fixedly connected to the upper surface of the fixed plate 506, the protrusion 509 is fixedly connected to the output end of the motor 507 through the connecting strip 508, and the top of the protrusion 509 is overlapped on the screening plate 504. There are two groups of screening devices, which are respectively arranged up and down inside the cabinet 1, and the screening plate 504 is placed at a certain angle. The filter hole of the upper screening plate 504 is larger than the filter hole of the lower screening plate 504. After the motor 507 is started, the protrusion 509 is driven to rotate or vibrate through the connecting strip 508. Since the protrusion 509 is in contact with the top of the screening plate 504, this rotation or vibration will be transmitted to the screening plate 504. The screening plate 504 begins to vibrate under the vibration transmitted by the motor 507 through the protrusion 509. This vibration of the screening plate 504 helps to promote the flow and stratification of the waste on the screening plate. The bottom of the spring 503 is fixedly connected to the upper surface of the support block 1 501 and the support block 2 502, and the top is fixedly connected to the lower surface of the screening plate 504. The existence of the spring not only provides the necessary support for the screening plate, but also can buffer the vibration, making the vibration of the screening plate 504 more stable and uniform. The waste enters the screening device from above and first contacts the upper screening plate 504. Due to the vibration of the screening plate 504, particles smaller than the size of the sieve hole pass through the sieve hole and fall into the screening plate 504 below. Therefore, multi-stage screening can be achieved to separate waste of different sizes.

[0035] Working principle: First, the device is moved to a suitable position by the universal wheel 3 at the bottom of the cabinet 1, and the waste is initially crushed or compacted by the roller in the feed bin 2, which is convenient for subsequent sorting and screening. The cylinder 802 drives the push plate 803 to slide along the buffer plate 8 to push the waste to the screening device. The magnetic block on the right side of the push plate 803 can absorb the metal waste to achieve the initial separation of the waste.

[0036] After the motor 507 is started, the connection bar 508 drives the protrusion 509 to rotate or vibrate, and then transmits the vibration to the screening plate 504. Under the action of vibration, the screening plate 504 causes the waste to flow and layer on the screening plate. The waste enters the screening device from above and first contacts the upper screening plate 504. Particles smaller than the size of the sieve holes fall through the sieve holes into the lower screening plate 504, and the waste remaining on the screening plate 504 enters the collector through the discharge plate.

[0037] Since there are two groups of screening devices, which are respectively arranged in the upper and lower parts of the cabinet 1, and the filter holes of the upper screening plate 504 are larger than the filter holes of the lower screening plate 504, multi-stage screening can be achieved to separate waste materials of different sizes. The dust suction pipe 1 702 and the dust suction pipe 2 704 absorb the dust in the feed bin 2 and the cabinet 1 respectively through the action of the suction pump 1 705 and the suction pump 2 707 to prevent the dust from scattering and flying. The collection box 7 is used to collect the dust sucked by the dust suction pipe.
