[0003] Therefore, how to avoid the caking of activated coke in the activated coke adsorption and filtration tank and improve the effective utilization rate of activated coke has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0004] In view of the above-mentioned defects of the prior art, the technical purpose of the utility model is to provide an activated coke adsorption and filtration tank, and the purpose is to avoid the caking of activated coke and improve the effective utilization rate of activated coke.

[0005] To achieve the above technical purpose, the utility model provides an activated coke adsorption and filtration tank, which includes a tank body. A wastewater inlet is arranged at the bottom of the tank body, and a new activated coke feeding port is arranged at the top.

[0006] A screw lifting device and a stirrer are arranged in the tank body. The top part of the screw lifting device is connected with a saturated waste coke discharge pipe, and one end of the saturated waste coke discharge pipe far away from the screw lifting device extends to the bottom position of the tank body.

[0007] An inlet water and backwashing water distribution device communicated with the wastewater inlet is further arranged at the bottom of the tank body.

[0008] Preferably, the tank body adopts the structural form of a moving bed.

[0009] Preferably, the screw lifting device is a screw conveyor.

[0010] Preferably, a wastewater outlet is arranged at the top of the filtration tank.

[0011] Advantages of the Utility Model

[0012] Due to the above structural design, the utility model effectively prevents the caking of activated coke in the filtration tank, improves the adsorption capacity of activated coke, that is, improves the effective utilization rate of activated coke, thus ensuring the good use effect and service life of activated coke in the filtration tank. Brief Description of the Drawings

[0013] Figure 1 It is a structural schematic diagram of the utility model.

[0014] In the figure: 1 is the pool body, 2 is the wastewater inlet, 3 is the saturated waste coke discharge pipe, 4 is the screw lifting device, 5 is the stirrer, 6 is the new activated coke feeding port, and 7 is the water inlet and backwashing water distribution device. Specific implementation mode

[0015] The following will further explain the concept, specific structure and technical effects generated by the present utility model in conjunction with the attached drawings to fully understand the purpose, features and effects of the present utility model.

[0016] Embodiment:

[0017] As Figure 1 shown, the activated coke adsorption and filtration pool includes a pool body 1. The bottom of the pool body 1 is provided with a wastewater inlet 2, and the top is provided with a new activated coke feeding port 6.

[0018] A screw lifting device 4 and a stirrer 5 are arranged in the pool body 1. The top part of the screw lifting device 4 is connected with a saturated waste coke discharge pipe 3, and one end of the saturated waste coke discharge pipe 3 far away from the screw lifting device 4 extends to the bottom position of the pool body 1.

[0019] The bottom of the pool body 1 is also provided with a water inlet and backwashing water distribution device 7 communicated with the wastewater inlet 2.

[0020] The main innovation of the present utility model is that the stirrer realizes the self-cleaning of the filter pool and prevents the activation of coke caking by means of mechanical disturbance combined with the backwashing of the pool body, thereby prolonging the service life of the activated coke.

[0021] The pool body 1 adopts the structure form of a moving bed. Compared with the traditional fluidized bed, the moving bed design can more effectively utilize the adsorption capacity of the activated coke and improve its effective utilization rate.

[0022] The screw lifting device 4 is a screw conveyor, which is used to discharge the saturated waste coke from the bottom of the pool body 1 and add new activated coke from the top of the pool body 1; the screw lifting device 4 is used instead of the traditional gas lifting device to more effectively control the discharge of the activated coke and the addition of new coke, and reduce the crushing and wear of the activated coke.

[0023] The water inlet and backwashing water distribution device 7 ensures uniform water distribution; the stirrer 5 stirs slowly, and realizes the self-cleaning and anti-caking of the filter pool 1 through mechanical disturbance combined with the backwashing water distribution device.

[0024] The top of the pool body 1 is provided with a wastewater outlet, and the wastewater outlet should be located above the activated coke layer added in the filter pool 1.

[0025] The working principle and usage process of the present utility model:

[0026] In practical applications, wastewater enters the tank body 1 through the wastewater inlet 2. First, it passes through the water inlet device 7, and then after being adsorbed and filtered by activated coke, the clean water is discharged through the wastewater outlet above the activated coke layer. The saturated waste coke is lifted by the spiral lifting device 4 and discharged from the saturated waste coke discharge pipe 3. At the same time, new activated coke is added from the top through the new activated coke feeding port 6, and the stirrer 5 operates regularly to prevent the activated coke in the tank body 1 from caking.

[0027] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in this technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
