Description

Technical Field

[0001] This utility model relates to the field of solid materials technology in coking wastewater, and in particular to an electrostatic separation device for separating solid materials in coking wastewater. Background Technology

[0002] In the treatment of coking wastewater, the separation of solid materials is a crucial step. Traditional separation methods are often inefficient and struggle to effectively remove impurities from solid materials. To overcome this challenge, electrostatic separation technology has been explored. Electrostatic separation utilizes the principle that different substances experience different electric forces in an electric field to achieve separation. However, after prolonged use, existing electrostatic separation equipment tends to accumulate impurities on the electrode plates, affecting subsequent separation efficiency. Therefore, there is a need for an electrostatic separation device that can automatically scrape impurities off the electrode plates and improve separation efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing electrostatic separation equipment where impurities easily remain on the electrode plates after prolonged use, affecting subsequent separation effects. Therefore, this invention proposes an electrostatic separation device for separating solid materials from coking wastewater.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electrostatic separation device for separating solid materials from coking wastewater includes two symmetrically arranged main support plates, a triangular plate fixedly connected between the two main support plates, two symmetrically arranged rotating rollers rotatably connected between the two main support plates, and a conveyor belt sleeved on the outer wall of the two rotating rollers via a pulley drive. An L-shaped mounting plate is fixedly connected to one side of each main support plate, and a drive assembly for driving the rotating rollers to rotate is provided on the top of the L-shaped mounting plate.

[0006] The main support plate has an installation cavity on one side, and an electrode plate is embedded inside the installation cavity. The main support plate is provided with multiple sets of scraping components for scraping off impurities on the surface of the electrode plate.

[0007] A collection component for collecting impurities is provided on the other side of the main support plate.

[0008] In one possible design, the drive assembly includes a servo motor fixedly connected to one side of an L-shaped mounting plate, with rotating rods fixedly connected to both ends of one of the rotating rollers. One end of each rotating rod rotatably passes through a main support plate. The output shaft of the servo motor is fixedly connected to one end of one of the rotating rods, and an eccentric rod is fixedly sleeved on the outer wall of the rotating rod.

[0009] In one possible design, the scraping assembly includes a sliding plate slidably connected to one side of the main support plate, a sliding box fixedly connected to the top of the sliding plate, and a third inclined groove formed on the side of the sliding box near the electrode plate.

[0010] In one possible design, the collecting assembly includes a side plate slidably connected to one side of the main support plate, with a first inclined groove on one side of the side plate and a second inclined groove on the top of the main support plate. The second inclined groove cooperates with the first inclined groove, and the side plate cooperates with an eccentric rod.

[0011] In one possible design, a fourth inclined groove is provided on one side of the sliding plate, and a connecting horizontal hole is provided at the bottom of the fourth inclined groove. A strip block is fixedly connected to one side of the conveyor belt, and the fourth inclined groove and the horizontal hole are used in conjunction with the strip block.

[0012] In one possible design, the same first collection box is provided on one side of both main support plates, and the interior of the first collection box is provided with multiple partitions.

[0013] In one possible design, a second collection box is provided on the other side of the two main support plates, and the second collection box is used in conjunction with the first inclined groove and the triangular plate.

[0014] In one possible design, the bottom of the main support plate is fixedly connected to two symmetrically arranged support legs, and the bottom of the two support legs is fixedly connected to the same base plate.

[0015] In this application, during use, coking wastewater solid materials are placed on top of the conveyor belt, the servo motor is started, the output shaft of the servo motor drives the rotating rod to rotate, the rotating rod drives the rotating roller to rotate, and the rotating roller drives the conveyor belt to move forward. By adjusting the voltage and current of the electrode plate, an electrostatic field with controllable intensity can be generated. When solid waste is sent into the electrostatic field, substances with different electrical properties will be subjected to different electric field forces, thereby achieving the separation of substances.

[0016] A small amount of impurities may remain on the surface of the electrode plate, which may affect the subsequent separation effect. At this time, the conveyor belt will also carry the strip block on the side along with it. The strip block enters the interior of the fourth inclined groove and drives the sliding plate to rise. The sliding plate drives the sliding box to rise. When the strip block enters the interior of the transverse hole and passes through, the sliding plate drives the sliding box to reset under the action of gravity.

[0017] In this way, the sliding box scrapes away the small amount of impurities remaining on the side of the electrode plate. When the sliding box moves to the highest point, the impurities detach from the electrode plate and enter the interior of the first inclined groove through the inclined surface of the second inclined groove, sliding down into the interior of the second collection box for collection. When the sliding box moves down, a small amount of impurities will also be pushed by the bottom of the sliding box to the surface of the triangular plate and slide down into the interior of the second collection box for collection. At the same time, when the rotating rod rotates, it can drive the eccentric rod to rotate. The eccentric rod pushes the side plate upward, which can help the impurities inside slide down quickly and avoid residue.

[0018] Beneficial effects: High-efficiency separation: By adjusting the voltage and current of the electrode plates, a controllable electrostatic field is generated. Substances with different electrical properties are subjected to different electric forces in the electric field, thereby achieving high-efficiency separation.

[0019] Automatic impurity removal: While conveying solid materials, the conveyor belt also carries the side strip blocks, which in turn lift the sliding plate and sliding box. Once the strip blocks pass through the horizontal holes, the sliding box returns to its original position under gravity, scraping away any remaining impurities on the side of the electrode plate. This design effectively prevents impurities from remaining on the electrode plate and improves the separation effect.

[0020] Impurity Collection: The scraped impurities slide down through the second and first inclined chute into the second collection box, completing the collection process. Simultaneously, the rotating rod also drives the eccentric rod to rotate, lifting the side plate upwards to help internal impurities slide down quickly, preventing residue. This design further improves the separation efficiency and cleanliness of the equipment.

[0021] Compact structure: The equipment has a compact overall structure, occupies a small area, and is easy to install and move. At the same time, the connections between various components are stable and reliable, ensuring long-term stable operation of the equipment.

[0022] Wide range of applications: This utility model is not only applicable to the separation of solid materials in coking wastewater, but can also be applied to other fields that require electrostatic separation, and has a wide range of application prospects. Attached Figure Description

Coking wastewater solid materials are placed on top of the conveyor belt 8. A servo motor 4 is started, and the output shaft of the servo motor 4 drives a rotating rod 15 to rotate, which in turn drives the rotating rollers 19 to rotate. The rotating rollers 19 then drive the conveyor belt 8 forward. By adjusting the voltage and current of the electrode plates 7, a controllable electrostatic field can be generated. When solid waste is sent into an electrostatic field, substances with different electrical properties will be subjected to different electric field forces, thereby achieving the separation of substances. An L-shaped mounting plate 16 is fixedly connected to one side of the main support plate 2.

The fourth inclined groove 21 and the horizontal hole 23 are used in conjunction with the strip block 18. A small amount of impurities will remain on the surface of the electrode plate 7, which may affect the subsequent separation effect.

The strip block 18 enters the interior of the fourth inclined groove 21 and drives the sliding plate 22 to rise. The sliding plate 22 drives the sliding box 11 to rise. When the strip block 18 enters the interior of the horizontal hole 23 and passes through, the sliding plate 22 drives the sliding box 11 to reset under the action of gravity.

[0031] On the other side of the main support plate 2, a collection assembly for collecting impurities is provided. The collection assembly includes a side plate 5 slidably connected to one side of the main support plate 2.

In this way, the sliding box 11 scrapes away the small amount of impurities remaining on the side of the electrode plate 7 upwards. When the sliding box 11 moves to the highest point, the impurities detach from the electrode plate 7 and enter the interior of the first inclined groove 6 through the inclined surface of the second inclined groove 12, and slide down into the interior of the second collection box 9 to complete collection. When the sliding box 11 moves downwards, a small amount of impurities will also be pushed by the bottom of the sliding box 11 to the surface of the triangular plate 17 and slide down into the interior of the second collection box 9 to complete collection. At the same time, when the rotating rod 15 rotates, it can drive the eccentric rod 10 to rotate. The eccentric rod 10 pushes the side plate 5 upwards, which can help the impurities inside slide down quickly and avoid residue.
