Description

Vertical rotary waste water processor

technical field

The utility model relates to a wastewater treatment device in the fields of environmental protection and metal resource recovery.

Background technique

In modern industrial production, some industrial enterprises, such as electroplating, copper clad laminates, circuit boards and other enterprises, will produce a large amount of industrial wastewater rich in Cu ²⁺ , Zn ²⁺ , Cr ⁶⁺ and other toxic and harmful substances. If these wastewaters are directly dumped into rivers, it will not only cause serious environmental pollution, but also cause a great waste of precious metal resources. At present, there are many treatment methods for this kind of wastewater, such as chemical method, electrolysis method, etc., but generally speaking, the treatment cost is relatively high, so there have been technologies that use cheap raw materials or waste materials as fillers to treat and recover heavy metal wastewater. However, most of them use fixed beds, the packing is still, the processing efficiency is low, and the packing is easy to agglomerate. There are also horizontal drums for treatment. Although the disadvantages of fixed bed processors are overcome, the power and floor space are relatively large, so we research and develop vertical rotary wastewater processors.

Contents of the invention

The purpose of this utility model is to provide a vertical rotary wastewater processor, which has a compact structure and a small footprint, can effectively remove harmful substances in industrial wastewater and replace precious metals in wastewater, which not only purifies the water quality, but also can be used as a Centralized treatment of waste and recycling of resources.

The technical solution of the utility model is to have a vertical rotating cylinder (8), the bottom of the vertical rotating cylinder (8) is an inverted cone, and the inverted cone can be movably fixed on the vertical rotating cylinder (8). The load-bearing device at the bottom of the outer channel steel support body (6), the vertical rotating cylinder (8) and the channel steel support (6) have at least one set of adjustment cylinder (8) verticality and support cylinder (8) rotation device, on the channel steel support body, a power device for driving the cylinder (8) to rotate is fixed, and there is a perforated plate (12) for the transverse partition at the junction of the inner straight body of the cylinder (8) and the inverted cone, and the cylinder (8) The inner wall has an inner anti-corrosion layer (9), and the inner center of the cylinder (8) is provided with a waste water inlet pipe (1) fixed on the channel steel support body (6), and the waste water inlet pipe (1) is inserted vertically downward Below the perforated plate (12), at least one retaining rod (7) is fixed on the waste water inlet pipe (1), and an overflow tank (2) and an outlet pipe (3) are arranged on the upper part of the cylinder body (8). 8) The space above the inner porous plate is filled with filler (10).

The above-mentioned inverted cone is provided with a sewage pipe (14), and the lower part of the channel steel bracket (6) is provided with a load-bearing steel ball group (16) and a rotating bearing (15) that can allow the cylinder (8) to rotate. A "∧" type water diffuser cover (17) is also arranged in the inverted cone, and the top of the diffuser cover is just below the outlet at the lower end of the water inlet pipe (1).

The utility model adjusts the verticality of the cylinder body (8) and supports the rotation device of the cylinder body (8). The screw rod (20) and the roller (19) are fixed on the corresponding channel steel support body and embedded in the horizontal direction of the cylinder body (8). In the ring bracket groove (21).

Above the indicated power unit of the present utility model is that on the channel steel support (6) be fixed with direct-connected reduction motor (22), there is small belt pulley (23) on the rotating shaft that motor (22) stretches out, and belt (24) is enclosed within On the large belt pulley (25) and the small belt pulley (23) of cylinder body (8) periphery.

The water outlet of the water outlet pipe (3) of the utility model is placed in the annular water tank (4) lower than the overflow tank (2), and the annular water tank (4) is provided with a treated water outlet pipe (5).

The working process of the utility model is as follows: industrial waste water with a certain pressure enters from the upper port of the pipe, rushes into the lower diffuser cover 17, forms a reverse splash and disperses the water flow, and enters the packing chamber through the porous plate to collide and replace with the packing. Impurities and displacement products fall into the lower inverted cone one after another. Driven by the power, the cylinder of the processor rotates slowly around the water inlet pipe continuously, and the waste water and filler in the cylinder are always stirred by the retaining rod on the water inlet pipe, which increases the contact area and maintains the replacement activity of the surface of the filler, achieving extreme Good processing effect. The waste water continuously collides with and reacts with the filler, and the waste water rises continuously. When it overflows the V-shaped mouth of the overflow tank, it flows into the overflow tank, rotates and sieves into the annular tank from the water outlet and flows out from the water outlet.

According to the actual operation and regulations, the sewage is discharged regularly and flows into the sewage collection pool for centralized recovery and other treatment of metal resources. When processor will carry out maintenance or when changing packing, can open the drain valve (not drawn among the figures) of the same horizontal position with the maintenance manhole (18) and put the upper water body, then open the manhole and just can carry out above-mentioned work.

The rotary vertical processor has the following outstanding advantages:

1. The waste water enters from the bottom, and it can fully contact the filler when it flows upstream.

2. The cylinder is constantly rotating, driving the packing to move, making the packing rub against each other, keeping the surface activity of the packing, and fully contacting with water, so as to achieve an excellent treatment effect.

3. The support is point contact, with small friction and power saving.

4. The water enters and exits in the rotating state, and the water distribution condition is better.

5. Low water inlet and high water outlet avoid further upgrade of subsequent treatment.

6. The vertical drum equipment is compact and occupies less land.
