Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically an activated carbon unloading and dewatering device. Background Technology

[0002] Activated carbon is widely used in wastewater treatment processes due to its strong adsorption properties. Unloading and dewatering are crucial steps in the use of activated carbon. Currently, traditional methods for unloading and dewatering activated carbon mostly involve simple filtration and sun-drying, or solid-liquid separation and drying using a single device. These traditional methods have several drawbacks. First, simple filtration cannot achieve efficient solid-liquid separation, leaving a significant amount of residual moisture in the activated carbon, affecting subsequent drying efficiency and the carbon's performance. Second, single-device drying equipment often fails to dry the activated carbon thoroughly and evenly, resulting in low drying efficiency and potential localized overheating, leading to a decrease in adsorption capacity. Furthermore, the transport and transfer of activated carbon during unloading in traditional equipment is cumbersome, easily causing carbon loss and contamination, increasing production costs. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an activated carbon unloading and dewatering device, which aims to solve the problems of inefficient solid-liquid separation, uneven drying and low efficiency, and cumbersome unloading and transportation that easily cause loss and pollution in traditional activated carbon unloading and dewatering methods, so as to achieve high-quality activated carbon unloading and dewatering.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an activated carbon unloading and dehydration device, including an activated carbon tank and a drying box.

[0006] In a preferred embodiment, a first through hole is provided on the side wall of the drying chamber, and the first conveyor belt passes through the first through hole into the drying chamber.

[0007] In a preferred embodiment, a V-shaped rod is provided on the inner wall of the drying oven, with one end of the V-shaped rod fixed to the inner wall of the drying oven and the other end positioned near the center point of the mesh plate.

[0008] In a preferred embodiment, a second through hole is provided on the side wall of the drying chamber, and a baffle rod is fixed on one side of the second through hole.

[0022] like Figure 1-2 In the present invention, an activated carbon unloading and dehydration device includes an activated carbon tank 1 and a drying box 7. The bottom of the activated carbon tank 1 is provided with a discharge pipe 2, and the bottom of the discharge pipe 2 is connected to a drain pipe 3. An inclined mesh plate 4 is provided inside the discharge pipe 2. A solid material outlet 5 is provided on the pipe wall of the discharge pipe 2 at the lower end of the inclined mesh plate 4. The inclined mesh plate 4 passes through the solid material outlet 5 and extends to the outside of the discharge pipe 2.

[0023] A first conveyor belt 6 is provided below the inclined mesh plate 4 outside the discharge pipe 2. The output end of the first conveyor belt 6 extends into the drying box 7. The drying box 7 is provided with a rotating disc 8 that can rotate. A mesh plate 9 is provided on the rotating disc 8. A hot air hood 12 is provided below the mesh plate 9.

[0024] In a preferred embodiment, the drying chamber 7 has a first through hole 701 on its side wall, and the first conveyor belt 6 passes through the first through hole 701 into the drying chamber 7.

[0025] In a preferred embodiment, a V-shaped rod 14 is provided on the inner wall of the drying oven 7. One end of the V-shaped rod 14 is fixed to the inner wall of the drying oven 7, and the other end is set near the center point of the mesh plate 9.

[0026] In a preferred embodiment, a second through hole 702 is provided on the side wall of the drying chamber 7, and a baffle rod 17 is fixed on one side of the second through hole 702. One end of the baffle rod 17 extends outside the drying chamber 7, and the other end is set close to the center point of the mesh plate 9.

[0027] In a preferred embodiment, a motor 10 is provided on the top of the drying chamber 7, and a vertical rotating shaft 11 is provided inside the drying chamber 7. The rotating shaft 11 passes through the center of the mesh plate 9 and is fixedly connected to the mesh plate 9.

[0028] The output shaft of the motor 10 is connected to the rotating shaft 11 for transmission.

[0029] In a preferred embodiment, the rotating disk 8 surrounding the mesh plate 9 is embedded in an annular groove on the side wall of the drying oven 7.

[0030] In a preferred embodiment, a guide plate 15 is provided below one end of the baffle rod 17 located outside the drying chamber 7, and a second conveyor belt 16 is provided below the guide plate 15.

[0031] In a preferred embodiment, the hot air hood 12 is located between the V-shaped rod 14 and the baffle rod 17, and a hot air outlet pipe 13 is provided on the top surface of the drying chamber 7 directly above the hot air hood 12.

[0032] The activated carbon unloading and dewatering device disclosed in this utility model is used when it is necessary to unload and dewater activated carbon in an activated carbon tank:

[0033] Open the discharge valve at the bottom of the activated carbon tank 1, and the activated carbon containing moisture enters the discharge pipe 2. Under the action of gravity, the moisture passes through the inclined mesh plate 4, flows along the inner wall of the discharge pipe 2 into the drain pipe 3 for discharge, while the activated carbon particles slide along the surface of the inclined mesh plate 4 and fall from the solid material outlet 5 onto the first conveyor belt 6. The first conveyor belt 6 transports the activated carbon into the drying box 7 and spreads it evenly on the mesh plate 9.

[0034] The motor is started, and the motor 10 drives the rotating shaft 11 to rotate, which in turn causes the rotating disk 8 and the mesh plate 9 to rotate synchronously. During this process, the V-shaped rod 14 spreads out the activated carbon that has entered the drying box 7 and formed a pile. Hot air at a temperature of 120°C and a wind speed of 5m / s is introduced into the hot air hood 12. The hot air is blown out evenly from the top of the hot air hood 12, drying the activated carbon on the mesh plate 9 that passes directly above the hot air hood 12.

[0035] After the activated carbon is dried, the rotating disc 8 continues to rotate. The activated carbon moves from the edge of the mesh plate 9 and passes through the second through hole 702 under the obstruction of the baffle rod 17. It then slides down onto the second conveyor belt 16 via the guide plate 15. The second conveyor belt 16 transports the dried activated carbon to the subsequent processing steps.

[0036] The activated carbon unloading and dehydration device described above can efficiently complete the unloading, dehydration and drying of activated carbon. In actual use, the solid-liquid separation effect is good, effectively meeting the needs of industrial production.
