Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically an activated carbon tank structure with an anti-caking unloading mechanism. Background Technology

[0002] In wastewater treatment processes, activated carbon tanks, as core adsorption equipment, are widely used in advanced treatment stages. They remove organic pollutants, heavy metals, and odor-causing substances from wastewater through the adsorption properties of activated carbon. Activated carbon needs to be replaced promptly after it becomes saturated, and the unloading efficiency directly affects the operating costs and treatment capacity of the wastewater treatment plant. Currently, most activated carbon tanks use side manholes for loading and unloading. This method relies on manual assistance. When activated carbon caking occurs due to the adsorption of high humidity and highly viscous pollutants, the material's flowability is significantly reduced, easily clogging the manhole and resulting in a slow unloading process that is difficult to clean thoroughly.

[0003] To address the aforementioned issues, existing technologies typically employ methods such as manual tapping of the tank, high-pressure water jet washing, or the addition of agitation devices to assist in unloading. Manual tapping is labor-intensive, inefficient, and carries the risk of damaging the tank structure; while high-pressure water jet washing can loosen compacted materials to some extent, it easily leaves wastewater residue, increasing the burden on subsequent treatment; traditional agitation devices have a simple structure and limited mixing range, making it difficult to effectively break up deeply compacted materials and failing to meet the requirements for efficient unloading. Furthermore, existing unloading mechanisms lack multi-stage crushing and refined control of the unloading process, resulting in high activated carbon residue rates, affecting tank lifespan and subsequent filling effectiveness. Therefore, there is an urgent need to design an unloading mechanism with efficient arch-breaking and multi-stage crushing functions to overcome the shortcomings of existing technologies and improve the unloading efficiency and reliability of activated carbon tanks. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an activated carbon tank structure with an anti-caking unloading mechanism, which solves the problems of difficult unloading, low efficiency and high residue rate caused by activated carbon caking when unloading activated carbon tanks through manholes in existing sewage treatment plants. This reduces the labor intensity of activated carbon tank unloading operations, avoids pollution residue and improves the crushing effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an activated carbon tank structure with an anti-caking unloading mechanism, including an activated carbon tank, wherein a rotating shaft is provided inside the activated carbon tank, the rotating shaft is a hollow shaft, a first inner sleeve shaft is provided inside the rotating shaft, the two ends of the first inner sleeve shaft extend to the outside of the two ends of the rotating shaft, a second inner sleeve shaft is provided inside the first inner sleeve shaft, the two ends of the second inner sleeve shaft extend to the outside of the two ends of the first inner sleeve shaft, and a third inner sleeve shaft is provided inside the first inner sleeve shaft, the two ends of the third inner sleeve shaft extend to the outside of the two ends of the second inner sleeve shaft;

[0006] The lower ends of the rotating shaft, the first inner sleeve shaft, the second inner sleeve shaft, and the third inner sleeve shaft are provided with multiple coarse, broken arc rods with gradually decreasing widths from bottom to top.

[0007] The upper ends of the rotating shaft, the first inner sleeve shaft, the second inner sleeve shaft and the third inner sleeve shaft extend to the outside of the top of the activated carbon tank, and the upper ends of the rotating shaft, the first inner sleeve shaft, the second inner sleeve shaft and the third inner sleeve shaft are all provided with driven bevel gears;

[0008] The activated carbon tank is equipped with two driving bevel gears of different sizes mounted on the same drive shaft at its top. The smaller driving bevel gear meshes with driven bevel gears on the first and second inner sleeve shafts, while the larger driving bevel gear meshes with driven bevel gears on the rotating shaft and the third inner sleeve shaft.

[0009] In a preferred embodiment, the two active bevel gears are mounted on the drive shaft of the first motor.

[0010] In a preferred embodiment, the bottom of the activated carbon canister is equipped with a pneumatic vibration mechanism.

[0011] In a preferred embodiment, the rotating shaft is provided with multiple layers of coarse crushing straight rods arranged radially, and the inner wall of the activated carbon canister is provided with multiple layers of fixed straight rods, with the multiple layers of coarse crushing straight rods and the multiple layers of fixed straight rods being staggered in the vertical direction.

[0012] In a preferred embodiment, the feed pipe at the bottom of the activated carbon tank is provided with two crushing wheels, and the outer walls of the two crushing wheels are provided with fine crushing rods, which are staggered on the vertical plane.

[0013] In a preferred embodiment, one end of the axle of each of the two crushing wheels extends out of the feed pipe, and the two crushing wheel axles located outside the feed pipe are synchronously driven by a second transmission belt.

[0014] In a preferred embodiment, a guide plate is provided at the upper opening of the feed pipe.

[0015] In a preferred embodiment, a second motor is provided on the outer wall of the feeding pipe, and the second motor is connected to the axle of one of the breaking wheels through a first transmission belt.

[0016] The activated carbon tank structure with an anti-caking unloading mechanism provided by this utility model has the following beneficial effects:

[0017] (1) The multi-layer nested shaft structure is adopted and coarse crushing arc rods of different widths are set. The coarse crushing straight rods on the rotating shaft and the fixed straight rods on the inner wall of the tank are arranged in an alternating manner to achieve three-dimensional crushing of activated carbon with different depths. The crushing wheel in the feed pipe and the fine crushing rods arranged in an alternating manner further crush the falling material, forming a multi-stage crushing system of "coarse crushing-fine crushing". Compared with the traditional single stirring device, it can effectively improve the crushing effect and shorten the unloading time.

[0018] (2) The multi-layer nested shafts achieve differentiated rotation through different active bevel gears. When encountering hard plateau areas, the multi-layer shafts work together to enhance the crushing force, thereby improving the crushing efficiency and effect.

[0019] (3) The pneumatic vibration mechanism at the bottom of the tank works in conjunction with the guide plate to assist the material to slide down using vibration. At the same time, the multi-layer crushing structure ensures that the material is fully loosened, effectively avoiding the residual accumulation of material at the bottom of the tank and in the discharge pipe.

[0028] The lower ends of the rotating shaft 2, the first inner sleeve shaft 3, the second inner sleeve shaft 4 and the third inner sleeve shaft 5 are provided with multiple coarse and broken arc rods 9 with gradually decreasing width from bottom to top;

[0029] The upper ends of the rotating shaft 2, the first inner sleeve shaft 3, the second inner sleeve shaft 4 and the third inner sleeve shaft 5 extend to the outside of the top of the activated carbon tank 1, and the upper ends of the rotating shaft 2, the first inner sleeve shaft 3, the second inner sleeve shaft 4 and the third inner sleeve shaft 5 are all provided with driven bevel gears 6;

[0030] The activated carbon tank 1 is equipped with two driving bevel gears 7 of different sizes on the top and mounted on the same drive shaft. The smaller driving bevel gear 7 meshes with the driven bevel gear 6 on the first inner shaft 3 and the second inner shaft 4, while the larger driving bevel gear 7 meshes with the driven bevel gear 6 on the rotating shaft 2 and the third inner shaft 5.

[0031] In a preferred embodiment, the two active bevel gears 7 are mounted on the drive shaft of the first motor 8.

[0032] In a preferred embodiment, the bottom of the activated carbon canister 1 is provided with a pneumatic vibration mechanism 10.

[0033] In a preferred embodiment, the rotating shaft 2 is provided with multiple layers of coarse crushing straight rods 11 arranged radially, and the inner wall of the activated carbon tank 1 is provided with multiple layers of fixed straight rods 12. The multiple layers of coarse crushing straight rods 11 and the multiple layers of fixed straight rods 12 are staggered in the vertical direction.

[0034] In a preferred embodiment, the feed pipe 101 at the bottom of the activated carbon tank 1 is provided with two crushing wheels 13, and the outer walls of the two crushing wheels 13 are provided with fine crushing rods 15, which are staggered on the vertical plane.

[0035] In a preferred embodiment, one end of the axle of each of the two crushing wheels 13 extends out of the feed pipe 101, and the two crushing wheels 13 located outside the feed pipe 101 are synchronously driven by the second transmission belt 17.

[0036] In a preferred embodiment, a guide plate 18 is provided at the upper opening of the feed pipe 101.

[0037] In a preferred embodiment, a second motor 15 is provided on the outer wall of the feed pipe 101, and the second motor 15 is connected to the axle of one of the breaking wheels 13 through the first transmission belt 16.

[0038] The present invention discloses the following method for unloading activated carbon:

[0039] Start the first motor 8 and the second motor 15, and simultaneously open the compressed air valve of the pneumatic vibration mechanism 10.

[0040] The first motor 8 drives two active bevel gears 7 to rotate. The smaller active bevel gear 7 drives the first inner shaft 3 and the second inner shaft 4 to rotate at a speed of 8 r / min, while the larger active bevel gear 7 drives the rotating shaft 2 and the third inner shaft 5 to rotate at a speed of 5 r / min. The coarse crushing arc rods 9 on each shaft rotate in different directions. At the same time, the coarse crushing straight rod 11, in conjunction with the fixed straight rod 12, performs three-dimensional crushing of the plated activated carbon in the tank. The coarse crushing straight rod 11 and the fixed straight rod 12 move alternately, initially crushing large pieces of plated material into smaller pieces.

[0041] At the same time, the pneumatic vibration mechanism 10 generates high-frequency vibration, causing the material at the bottom of the tank to loosen and slide down. The crushed material enters the feed pipe 101 through the guide plate 18 and falls onto the crushing wheel 13 on one side. The second motor 15 drives the two crushing wheels 13 to rotate in the same direction at a speed of 15 r / min through the first transmission belt 16 and the second transmission belt 17. The fine crushing rod 15 performs secondary crushing on the falling material, making it into smaller particles, and finally discharges it from the tank through the feed pipe 101.

[0042] During the unloading process, the operator can adjust the speed of the first motor 8 and the second motor 15, as well as the vibration frequency of the pneumatic vibration mechanism 10, through the control cabinet to adapt to different degrees of activated carbon caking and ensure efficient and thorough unloading. After unloading is completed, the motors and the pneumatic vibration mechanism 10 are turned off, completing one unloading operation.
