Description

Technical Field

[0001] This utility model relates to the technical field of sodium chloride disc dryers, specifically a sodium chloride disc dryer for coking wastewater. Background Technology

[0002] After dehydrating coking wastewater, sodium chloride containing moisture is obtained, which needs to be dried. A disc dryer is often used for this purpose. A disc dryer is a vertical, continuous drying device with multiple layers of fixed hollow heated circular trays, rotating rakes for stirring, and heat conduction as the main method. In this drying process, the heat carrier is passed into each layer of hollow discs to indirectly heat the wet material placed on the disc surface through heat conduction. Under the scraping action of the rotating rake blades, the moisture in the constantly moving and rolling material evaporates at the operating temperature. The steam is discharged with the exhaust gas of the equipment, thereby continuously obtaining qualified dried finished products at the bottom of the equipment.

[0003] In existing disc dryers, the feed inlet is usually a direct feed pipe. However, undried sodium chloride is poured directly into the feed pipe, resulting in a single feed point. This leads to poor initial material dispersion and the undried sodium chloride is prone to clumping, affecting the feeding effect.

[0004] Therefore, it is proposed to use a sodium chloride disc dryer to solve the problems mentioned above for coking wastewater. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sodium chloride disc dryer for coking wastewater. It solves the problems of existing disc dryers, where the feed inlet is usually a direct feed pipe, but undried sodium chloride is directly poured into the feed pipe, resulting in a single feed point, poor initial material dispersion, and easy clumping of undried sodium chloride, which affects the feeding effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a disc dryer body, wherein a feeding mechanism is provided on the top of the disc dryer body, the feeding mechanism includes a feeding pipe, a distributing pipe and a distributing cone, the feeding pipe is provided on the top of the disc dryer body, the distributing pipe is fixedly connected to the bottom outer side of the feeding pipe, and the distributing cone is integrally formed at the bottom of the inner cavity of the feeding pipe; the disc dryer body includes a lever and a drying disc.

[0007] Preferably, an auxiliary feeding mechanism is provided on the inner side of the feed pipe. The auxiliary feeding mechanism includes a bracket, a motor, a rotating shaft, a convex plate, and a scraper. The bracket is fixedly connected to the top of the feed pipe, the motor is fixedly connected to the top of the bracket, the rotating shaft is fixedly connected to the output shaft of the motor, the convex plate is fixedly connected to the outer side of the rotating shaft, and the scraper is fixedly connected to one end of the rotating shaft.

[0008] Preferably, four scraper blades are provided, which are equidistantly distributed on the outer side of one end of the rotating shaft, and the convex plates are equidistantly distributed on the outer side of the rotating shaft.

[0009] Preferably, the outer wall of the scraper is in contact with the outer wall of the distribution cone, and a screening mechanism is provided on the inner side of the feed pipe.

[0010] Preferably, the screening mechanism includes a mesh grid, a protrusion, a guide groove, a guide rod, a spring, a drag rod, a ball bearing, and an annular frame. The inner side of the feed pipe is provided with a mesh grid, the protrusion is integrally formed on the outer side of the mesh grid, the outer side of the protrusion is slidably connected to the guide groove, the guide rod is fixedly connected to the inner side of the guide groove, the spring is sleeved on the outer side of the guide rod, the drag rod is fixedly connected to the outer side of the rotating shaft, one end of the drag rod is rotatably connected to a ball bearing, and the annular frame is integrally formed on the bottom of the mesh grid.

[0011] Preferably, the bottom of the annular frame is corrugated, and the ball bearings are attached to the bottom of the annular frame.

[0012] Preferably, the rotating shaft passes through the rotating connecting mesh grid, and the top of the mesh grid has a through hole, which is not fitted to the outer wall of the rotating shaft.

[0013] Compared with the prior art, this utility model provides a sodium chloride disc dryer for coking wastewater, which has the following beneficial effects: After dewatering coking wastewater, sodium chloride containing moisture is obtained and needs to be dried. The sodium chloride is placed on the mesh screen of the feed pipe. The mesh screen vibrates up and down, causing the sodium chloride to fall onto the distribution cone. Guided by the distribution cone, the sodium chloride is diverted from the four distribution pipes into the disc dryer body for drying, preventing the material from accumulating directly and affecting the initial drying effect. The motor drives the convex plate and scraper plate on the rotating shaft to rotate. The convex plate further disperses the material, while the scraper plate prevents sodium chloride from accumulating on the distribution cone, resulting in better material discharge.

[0014] Sodium chloride is poured onto a mesh screen and fed through it. When the motor rotates, it synchronously drives the drag bar to rotate. The ball bearings adhere to the bottom of the annular frame, and together with the corrugated structure at the bottom of the annular frame, they push the mesh screen and compress the spring. With the spring's rebound, the mesh screen moves up and down, sieving and feeding the sodium chloride. During sieving, the sodium chloride can be dispersed and fed out, and larger clumps of sodium chloride can be separated. The vibration also helps to break up clumps of sodium chloride, preventing feed blockage. Attached Figure Description

[0020] After dewatering the coking wastewater, sodium chloride containing moisture is obtained, which needs to be dried. It is placed on the mesh grid 15 of the feed pipe 2. The mesh grid 15 vibrates up and down, and the sodium chloride falls onto the distribution cone 4. The distribution cone 4 guides the sodium chloride to flow from the four distribution pipes 3 into the disc dryer body 1 for drying, preventing the material from accumulating directly and affecting the initial drying effect. The motor 11 drives the convex plate 13 and scraper 14 on the rotating shaft 12 to rotate. The convex plate 13 further disperses the material, while the scraper 14 can prevent sodium chloride from accumulating on the distribution cone 4, resulting in a better material feeding effect.

[0021] Furthermore, four scraper plates 14 are provided, which are equidistantly distributed on the outer side of one end of the rotating shaft 12, and the convex plates 13 are equidistantly distributed on the outer side of the rotating shaft 12.

[0022] Furthermore, the outer wall of the scraper 14 is in contact with the outer wall of the distribution cone 4, and a screening mechanism is provided on the inner side of the feed pipe 2.

With the help of the corrugated structure at the bottom of the annular frame 22, the mesh grid 15 is pushed and the spring 19 is compressed. With the rebound of the spring 19, the mesh grid 15 moves up and down to screen and feed the sodium chloride. During the screening, the sodium chloride can be dispersed and the larger clumps of sodium chloride can be separated. The vibration can also disperse the clumps of sodium chloride and prevent the feed from getting blocked.

[0025] Furthermore, the bottom of the annular frame 22 is corrugated, and the ball bearing 21 is attached to the bottom of the annular frame 22.

[0026] Furthermore, the rotating shaft 12 passes through the rotating connecting mesh 15, and the top of the mesh 15 has a through hole, which does not fit with the outer wall of the rotating shaft 12.

[0027] The working principle of the above embodiment is as follows: After dehydrating the coking wastewater, sodium chloride containing moisture is obtained, which needs to be dried. It is placed on the mesh grid 15 of the feed pipe 2. The mesh grid 15 vibrates up and down, causing the sodium chloride to fall onto the distribution cone 4. Guided by the distribution cone 4, the sodium chloride is diverted from the four distribution pipes 3 into the disc dryer body 1 for drying, preventing direct accumulation of material and affecting the initial drying effect. The motor 11 drives the convex plate 13 and scraper plate 14 on the rotating shaft 12 to rotate. The convex plate 13 further disperses the material, while the scraper plate 14 prevents sodium chloride from accumulating on the distribution cone 4, thus achieving a more effective drying process. Good feeding effect: Sodium chloride is poured onto the mesh grid 15 and fed through the mesh grid 15. When the motor 11 rotates, it synchronously drives the drag rod 20 to rotate. The ball bearing 21 is attached to the bottom of the annular frame 22. With the corrugated structure at the bottom of the annular frame 22, the mesh grid 15 is pushed and the spring 19 is compressed. With the rebound of the spring 19, the mesh grid 15 moves up and down to screen and feed the sodium chloride. During screening, the sodium chloride can be dispersed and fed, and large clumps of sodium chloride can be separated. Vibration can also disperse clumps of sodium chloride and prevent feed blockage.
