Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to a solid-containing wastewater regeneration device. Background Art

[0002] Packed tower filtration is often used for industrial water purification. The industrial wastewater to be treated enters the device from the top of the packed tower. The industrial wastewater passes through the gaps in the packing and is discharged from the purified water pipeline below the packed tower. The solid particles in the industrial wastewater are retained by the packing to achieve the purification effect.

[0003] When impurities in the packed tower continue to accumulate and the purification effect gradually weakens, the packing needs to be cleaned. The existing cleaning method usually requires opening the packed tower, draining the water, pouring out the packing, then cleaning the impurities on the packing, and finally reassembling it. This method is not only time-consuming and labor-intensive, but also inefficient. Summary of the invention

[0004] In order to solve the problem in the prior art that when cleaning the packing, it is usually necessary to open the packing tower to clean the packing, which is time-consuming, labor-intensive and inefficient, the utility model proposes a solid-containing wastewater regeneration device, which realizes cyclic cleaning of the packing through spiral blades and a backflow sleeve, does not need to disassemble the packing tower, and saves time and resources.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A solid wastewater regeneration device comprises a packing tower body and a drive shaft, wherein the drive shaft is located inside the packing tower body, one end of the drive shaft penetrates through a tank body and is connected to a drive mechanism, a propeller blade is arranged on the surface of the drive shaft, and a guide sleeve is arranged outside the propeller blade;

[0007] A packing bed is arranged inside the packed tower body, a slurry pipe is arranged on one side of the upper end of the packed tower body, a valve one is arranged on the slurry pipe, a wastewater pipe is arranged on the other side of the upper end of the packed tower body, a valve two is arranged on the wastewater pipe, a purified water pipe is arranged on one side of the lower end of the packed tower body, a valve three is arranged on the purified water pipe, and a clean water pipe is arranged on the other side of the lower end of the packed tower body, a valve four is arranged on the clean water pipe.

[0008] Furthermore, the ratio of the diameter D2 of the guide sleeve to the diameter D1 of the outer wall of the packed tower body is D2 / D1=1 / 4-3 / 4, and the ratio of the diameter D3 of the propeller blade to the diameter D2 of the guide sleeve is D3 / D2=1 / 4-3 / 4.

[0009] Furthermore, the height of the packing bed is higher than the height of the guide sleeve by ΔH, where ΔH=0.25D2 to 1.5D2.

[0010] Furthermore, the guide sleeve is a central rotating body, and its rotation axis is the same as the axis of the drive shaft. The upper edge and the lower edge of the guide sleeve are respectively aligned with the upper end and the lower end of the propeller blade.

[0011] Furthermore, the propeller blades are axial-flow blades, and a certain gap is provided between the propeller blades and the inner wall of the guide sleeve.

[0012] Furthermore, a supporting member is provided at the bottom of the packed tower body to facilitate supporting the packed tower body.

[0013] Through the above technical solution, the beneficial effects of the utility model are:

[0014] The utility model arranges axial-flow propeller blades and a guide sleeve coaxially arranged therewith in the packing tower body. When cleaning the packing, clean water enters the packing tower body from the bottom of the packing bed to fluidize the packing bed. At this time, the driving shaft drives the axial-flow propeller blades to rotate at a low speed, generating a flow field from bottom to top to transport the packing to the upper edge of the guide sleeve. After moving to the upper edge of the guide sleeve, the packing falls between the guide sleeve and the wall surface of the packing tower body due to the action of gravity. When it reaches the bottom of the packing tower body, it is lifted from the inside of the guide sleeve due to the action of the axial-flow propeller blades, thereby cyclically cleaning the packing; the solid particles in the packing are discharged to the slurry pipe above the packing tower body along with the clean water, thereby realizing the cleaning of the packing, without the need to disassemble and clean the packing tower body, and the cleaning efficiency is high.

[0015] The utility model utilizes the cooperation of axial-flow propeller blades and guide sleeves to produce a large vertical circulation of the filler under the conditions of lower drive shaft speed and clean water flow, and can achieve cleaning of the filler under the conditions of lower energy consumption and water consumption.
