Description

Technical Field

[0001] This utility model relates to the field of coking waste liquid filtration technology, specifically a preliminary filtration device for coking waste liquid. Background Technology

[0002] Coking wastewater is a high-concentration organic wastewater generated in the coking industry. It mainly includes residual ammonia water and process wastewater, and contains high concentrations of phenols, polycyclic aromatic hydrocarbons, benzene series compounds and other recalcitrant organic pollutants, as well as ammonia nitrogen, cyanide, heavy metals and other pollutants. It is highly toxic and polluting. Direct discharge will seriously damage the ecological environment and endanger human health. It is difficult to treat and requires a combination of pretreatment, biochemical treatment and advanced treatment processes to meet the standards.

[0003] When coking waste liquid undergoes preliminary filtration, it is usually simply filtered through a filter plate to remove impurities. However, after prolonged use, impurities tend to adhere to the surface of the filter plate, which can affect its permeability and reduce the preliminary filtration effect of the coking waste liquid.

[0009] Furthermore, the drive assembly includes: a rotating gear, a drive gear, and a first motor. The rotating gear is fixedly connected to a rotating rod, the drive gear is rotatably connected to a support plate, and the drive gear meshes with the rotating gear. The first motor is mounted on the support plate, and the output end of the first motor passes through the support plate and is fixedly connected to the drive gear.

[0010] Furthermore, the rebound assembly includes: a fixed rod, a rotating seat, a baffle, and a torsion spring. The fixed rod is fixedly connected to the other end of the connecting rod, the rotating seat is fixedly connected to the filter box, the fixed rod is rotatably connected inside the rotating seat, the baffle is fixedly connected to one end of the fixed rod, and the torsion spring is sleeved on the circumferential surface of the fixed rod.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a preliminary filtration device for coking waste liquid, which has the following beneficial effects:

[0015] This preliminary filtration device for coking waste liquid uses a rotating mechanism to facilitate the rotation of multiple filter boxes. These boxes alternately enter the collection tank to remove impurities from the coking waste liquid. As the filter boxes rotate, they impact the top of the collection tank, generating a vibration that pours the impurities from the filter boxes into the collection tank. A reciprocating mechanism then moves the collection tank, creating half-space for the filter boxes to rotate. As the filter boxes rest on the collection tank and continue to rotate, they rotate on a fixed rod, ensuring the passage of the filter boxes. After passage, a torsion spring returns the filter boxes to their original position, and this process is repeated, effectively preventing clogging and improving the filtration efficiency of the coking waste liquid.

Multiple filter boxes 2 are provided and are installed inside the housing 1 by a rotating mechanism. The rotating mechanism is used to drive the multiple filter boxes 2 to alternately filter the coking waste liquid. The collection box 3 is installed at the top of the housing 1 by a reciprocating moving mechanism. The reciprocating moving mechanism is used to drive the collection box 3 to reciprocate when the filter boxes 2 are alternately installed. A discharge port is opened on one side of the housing 1, and the discharge box 4 is connected to the discharge port.

[0023] The rotating mechanism includes: a support plate 5, a rotating rod 6, a connecting rod 7, and a drive assembly. Two support plates 5 are provided, both fixedly connected to the top of the housing 1. The two ends of the rotating rod 6 are rotatably connected to the two support plates 5 respectively. Multiple connecting rods 7 are provided, each fixedly connected to the circumferential surface of the rotating rod 6. The other end of each connecting rod 7 is connected to a filter box 2 via a spring-loaded assembly. The drive assembly is mounted on one of the support plates 5 and is used to drive the rotating rod 6 to rotate. The drive assembly includes: a rotating gear 8, a drive gear 9, and a first motor 10. The rotating gear 8 is fixedly connected to the rotating rod 6, and the drive gear 9 rotates... The drive gear 9 is meshed with the rotating gear 8 and is connected to the support plate 5. The first motor 10 is mounted on the support plate 5. The output end of the first motor 10 passes through the support plate 5 and is fixedly connected to the drive gear 9. The rebound assembly includes: a fixed rod 11, a rotating seat 12, a baffle 13 and a torsion spring 14. The fixed rod 11 is fixedly connected to the other end of the connecting rod 7. The rotating seat 12 is fixedly connected to the filter box 2. The fixed rod 11 is rotatably connected inside the rotating seat 12. The baffle 13 is fixedly connected to one end of the fixed rod 11. The torsion spring 14 is sleeved on the circumferential surface of the fixed rod 11. The two ends of the torsion spring 14 are fixedly connected to the rotating seat 12 and the baffle 13, respectively.

[0024] The reciprocating movement mechanism includes: rollers 15, push rods 16, linkage rods 17, and a power assembly. Multiple rollers 15 are rotatably connected to the bottom of the collection box 3. Grooves are formed on the circumferential surface of each roller 15, and the edge of the box 1 is located within these grooves. One end of the push rod 16 is rotatably connected to one side of the collection box 3. One end of the linkage rod 17 is fixedly connected to the other end of the push rod 16. The power assembly is located inside the box 1 and is used to drive the linkage rod 17 to swing. The power assembly includes: a stabilizer 18, a drive rod 19, and a second motor 20. The stabilizer 18 is fixedly connected inside the box 1. One end of the drive rod 19 is rotatably connected to the stabilizer 18, and the other end of the drive rod 19 is rotatably connected to the other end of the linkage rod 17. The second motor 20 is mounted on the stabilizer 18, and its output end passes through the stabilizer 18 and is fixedly connected to the drive rod 19.

[0025] The working principle is as follows: When coking waste liquid needs to be filtered, it is introduced into the tank 1 and flows towards the discharge port. During the flow, the first motor 10 drives the drive gear 9 and the rotating gear 8 to rotate, which in turn drives the rotating rod 6 and the connecting rod 7 to rotate, thereby driving multiple filter boxes 2 to rotate. The multiple filter boxes 2 alternately remove impurities from the coking waste liquid. Then, as the filter boxes 2 rotate, they hit the top of the collection box 3. The moment of contact generates a knocking vibration, which pours the impurities in the filter boxes 2 into the collection box 3. Then, the second motor 20 drives the drive rod 19 to rotate. When the drive rod 19 rotates, it drives the linkage rod 17 to swing. When the linkage rod 17 swings, it drives the push rod 16 to push the collection box 3 to move, thus making room for the filter boxes 2 to rotate. When the filter boxes 2 are placed on the collection box 3 and continue to rotate, they rotate on the fixed rod 11, thus ensuring the passage of the filter boxes 2. After passage, the torsion spring 14 drives the filter boxes 2 to return to their original position.
