Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a wet slag drying equipment with heat exchange capability. Background Technology

[0002] Solid waste containing a certain amount of moisture, such as slag, coal slime, and sludge, is generated during industrial production. If these wet slags are not treated, they may cause a series of environmental problems, such as polluting soil and water sources, producing foul odors, and even breeding bacteria and viruses. Drying wet slag can not only reduce its volume and weight, lower transportation and storage costs, but also make it available for resource utilization, such as as building materials, fertilizers, or energy. Therefore, it is necessary to design a wet slag drying device.

[0003] To address this, patent CN218296609U discloses a wet slag drying device, comprising a base plate, which is a plate, with a material box at the upper end of the base plate, the material box containing steel slag; an adjustable base at the lower end of the base plate, with pulleys at the lower end of the base plate; and a cover, which is mounted on the upper end of the base plate via a lifting mechanism. The cover has a square pyramidal structure, and an electric heater is mounted on the upper end of the cover. This wet slag drying device has a simple structure. It mainly uses the cover and material box to place the steel slag, and then uses a heating device and a stirring mechanism to heat it. The stirring mechanism is driven by a motor to achieve stirring and leveling. The material box is exposed, which is convenient for regular cleaning and maintenance. At the same time, the base is equipped with a moving mechanism to facilitate transportation and movement of the device, increasing its practicality.

[0004] Although the aforementioned wet slag drying device is convenient for regular cleaning and maintenance, the prolonged hot air drying process during wet slag drying leads to high-load operation of the equipment, resulting in energy waste and a gradual decrease in drying efficiency. Therefore, it is necessary to design a wet slag drying device that can exchange heat and cold. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 The present invention provides a wet residue drying device with heat exchange capability, including a base 1.

[0028] Reference Figures 1-5 The top of the base 1 is fixed with a discharge structure 2, which includes a support column 21, a support plate 22, a movable block 23, a hydraulic rod 24, a movable groove 25, and a slide rod 26. The support column 21 is evenly fixed on one side of the top of the base 1, and the hydraulic rod 24 is evenly fixed on the other side of the top of the base 1. The top of the support column 21 is hinged to the support plate 22. The bottom of the support plate 22 is evenly provided with a movable groove 25 on the side near the hydraulic rod 24. The movable groove 25 is provided with a movable block 23 inside, and the slide rod 26 is slidably connected inside the movable block 23. The support column 21 and the hydraulic rod 24 are symmetrically distributed on both sides of the base 1. The bottom end of the movable block 23 is hinged to the top end of the hydraulic rod 24, and both ends of the slide rod 26 are fixedly connected to the inner wall of the support plate 22.

[0029] With an external power supply, the hydraulic rod 24 extends and retracts to push the movable block 23 to move on the slide rod 26. The movable block 23 drives the support plate 22 to rotate around the support column 21 through the hinge point, changing the tilt angle of the support plate 22. Subsequently, the wet slag will slide down along the tilted drying box 35 due to gravity. The door panel 31 is opened to discharge the slag. When discharging the slag, the stirring rod 38 is reset in advance so that the stirring rod 38 is above the drying box 35, avoiding the impact of the slag on the stirring rod 38 when it falls.

[0030] Reference Figures 1-5A drying structure 3 is fixed to one side of the top of the discharge structure 2. The drying structure 3 includes a door panel 31, a drive motor 32, a protective plate 33, a feed pipe 34, a drying box 35, a heating box 36, a central shaft 37, and stirring rods 38. The drying box 35 is fixed to one side of the top of the support plate 22. A protective plate 33 is fixed to one end of the drying box 35. The door panel 31 is hinged to the bottom end of the protective plate 33. The feed pipe 34 is fixed inside the protective plate 33. A drive motor 32 is fixedly installed on one side of the bottom of the protective plate 33. A heating box 36 is fixedly installed on the inner wall of the drying box 35. A central shaft 37 is set inside the drying box 35. Stirring rods 38 are evenly fixed to the top of the central shaft 37. One end of the central shaft 37 extends to the outside of the protective plate 33 and is fixedly connected to the output end of the drive motor 32. The other end of the central shaft 37 extends to the inside of the drying box 35 and is rotatably connected to the drying box 35. The stirring rods 38 are evenly distributed on the outer wall of the central shaft 37.

[0031] With an external power supply, the wet slag enters the drying chamber 35 through the feed pipe 34. The drive motor 32 is started, and the drive motor 32 drives the stirring rod 38 to rotate through the central shaft 37, dispersing the wet slag and making the wet slag evenly heated inside the drying chamber 35. After the heating chamber 36 is started, it heats the air inside the drying chamber 35. The hot air comes into contact with the wet slag and evaporates the moisture in the wet slag. The dried slag is discharged out from the door panel 31.

[0032] Reference Figures 1-5 A heat exchange structure 4 is provided on one side of the drying structure 3 at the top of the discharge structure 2. The heat exchange structure 4 includes an exchange box 44 fixed to one side of the top of the discharge structure 2. A cover 43 is provided at the top of the exchange box 44. An air hole 42 is opened inside the cover 43. An exhaust pipe 41 is fixed on one side inside the cover 43. An suction fan 47 is fixedly installed inside the exchange box 44 on the side close to the drying structure 3. A processing box 46 is provided on the side of the suction fan 47 away from the drying structure 3. An air supply pipe 45 is fixed on the top of the exchange box 44 on the side close to the drying structure 3. A valve is provided inside the exhaust pipe 41. The ends of the exhaust pipe 41 and the air supply pipe 45 away from the exchange box 44 both extend into the interior of the drying box 35. An activated carbon bag is provided inside the processing box 46.

[0033] With an external power supply, the suction fan 47 draws hot and humid air from the drying chamber 35 into the exchange chamber 44. The air is purified by the activated carbon pack inside the treatment chamber 46 and then returned to the drying chamber 35 for reuse through the air supply pipe 45, thus realizing the recycling of hot air. If a large amount of cold air is needed to enter the drying chamber 35, the valve inside the exhaust pipe 41 can be closed, and the suction fan 47 can be used to draw cold air into the exchange chamber 44 through the air hole 42. Then, the cold air is sent into the drying chamber 35 through the air supply pipe 45, which facilitates the exchange of hot and cold air. After the cold air enters the drying chamber 35, it can enhance the airflow turbulence inside the drying chamber 35, improve drying efficiency, and shorten drying time.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
