A horizontal frame plate is provided inside the drying box, and multiple mesh plates are provided on the frame plate. Gaps are left between the multiple mesh plates to form a variable diameter discharge port. Multiple push boxes are provided one-to-one above the multiple mesh plates. A discharge branch pipe is provided on the top surface of the drying box above the push box. The multiple discharge branch pipes are connected to the same screw conveyor mechanism.

[0009] The movable frame has a toothed bar on each of its upper and lower inner walls, and a half gear is provided on the track plate. The half gear is located inside the movable frame and intermittently meshes with the toothed bars on the upper and lower sides of the movable frame through rotation.

[0014] The activated carbon unloading and processing system for the activated carbon tank provided by this utility model has the following beneficial effects by adopting the above structure:

[0015] (1) The spiral blades of the spiral conveying mechanism agitate the activated carbon in the manhole, which can effectively solve the problem of inconvenient output of caking activated carbon.

[0016] (2) The activated carbon fed into the drying box can fall into the pusher box and come into contact with the rising hot air to achieve drying. Then, the activated carbon is discharged by the reciprocating motion of the pusher box. Compared with the current direct loading and unloading of activated carbon, it can effectively avoid the situation where sewage is discharged along with the activated carbon.

[0017] (3) After the activated carbon is initially dried in the tank through the hot air inlet pipe and two hot air branch pipes, the moisture brought into the drying box by the activated carbon is reduced. After a second hot air drying in the drying box, the dryness of the output activated carbon is guaranteed. Attached Figure Description

The drying box 2 has a horizontal frame plate 3 inside, and multiple mesh plates 4 are provided on the frame plate 3. The multiple mesh plates 4 are spaced apart to form a variable diameter discharge port 5. Multiple push boxes 6 are provided directly above the multiple mesh plates 4. A discharge branch pipe 16 is provided on the top surface of the drying box 2 directly above the push box 6. The multiple discharge branch pipes 16 are connected to the same screw conveyor mechanism 15. One end of the screw conveyor mechanism 15 extends into the activated carbon tank 1 through the manhole 101.

[0023] The spiral blades of one end of the spiral conveying mechanism 15, which extends into the activated carbon tank 1, extend out of the housing of the spiral conveying mechanism 15.

[0024] In a preferred embodiment, among the plurality of pusher boxes 6, the outer walls of two adjacent pusher boxes 6 are connected and fixed by a connecting rod 8. The outer wall surface of one end of the pusher box 6 facing the side wall of the drying chamber 2 is provided with a connecting rod 8 that passes through the side wall of the drying chamber 2. The end of the connecting rod 8 located outside the drying chamber 2 is connected to a reciprocating mechanism 9 provided on the outer wall of the drying chamber 2.

[0025] In a preferred embodiment, the horizontal cross-sectional dimension of the pusher box 6 is the same as the top surface dimension of a single mesh plate 4.

[0026] In a preferred embodiment, the reciprocating mechanism 9 includes a track plate 10 fixed to the outer wall of the drying chamber 2, and a movable frame 11 capable of lateral movement is provided inside the track plate 10. The end of the connecting rod 8 located outside the drying chamber 2 is fixedly connected to one end of the movable frame 11.

[0027] The movable frame 11 has a toothed bar 12 on the inner walls of the upper and lower sides respectively, and a half gear 13 is provided on the track plate 10. The half gear 13 is located inside the movable frame 11, and the half gear 13 intermittently meshes with the toothed bar 12 on the upper and lower sides of the movable frame 11 through rotation.

[0028] In a preferred embodiment, the half gear 13 is driven to rotate by a drive motor 14 disposed on one side of the track plate 10.

[0029] In a preferred embodiment, the inner walls on both sides of the drying box 2 are provided with transverse guide grooves 7, and the outer wall of the pusher box 6 is provided with a protrusion located within the guide grooves 7.

[0030] In a preferred embodiment, the bottom surface of the drying chamber 2 is inclined, and a discharge port 20 is provided at the lower end of the bottom surface of the drying chamber 2.

The first hot air branch pipe 18 and the second hot air branch pipe 19 are connected to the hot air inlet pipe 17.

[0032] The activated carbon unloading and processing system disclosed in this invention, when in operation:

[0033] The screw conveyor mechanism 15 is activated, and the screw blades inside the activated carbon tank 1 begin to agitate and convey the clumped activated carbon. The activated carbon is fed into the drying chamber 2 by the screw conveyor 15 and falls into the pusher box 6 on the mesh plate 4. Some moisture passes through the mesh plate 4 and is discharged from the outlet 20 for collection and further processing. At this time, the reciprocating mechanism 9 is activated, and the drive motor 14 drives the half gear 13 to rotate, causing the movable frame 11 to move back and forth along the track plate 10, thereby pushing the pusher box 6 to move. The pusher box 6 pushes the activated carbon to the variable diameter discharge port 5. Due to the design of the discharge port, the material can fall smoothly to the bottom of the drying chamber 2.

[0034] Throughout the process, hot air enters the drying chamber 2 through the hot air inlet pipe 17 and the first hot air branch pipe 18, while the second hot air branch pipe 19 delivers hot air into the activated carbon tank 1 to achieve pre-drying of the activated carbon.

[0035] The dried activated carbon is discharged through the discharge port 20 at the bottom of the drying box 2, completing the entire unloading and drying process.

[0036] This application solves the problem of inconvenient unloading after activated carbon caking through the above structure, and achieves effective water removal of the unloaded activated carbon, thus avoiding environmental pollution.
