Description

Pulse jump asynchronous vibration wave dynamic membrane frame

technical field

The utility model belongs to the technical field of sewage treatment, and is used for treating industrial waste water such as metallurgy, mining, power generation, coal mining, etc., and particularly relates to a pulsation jumping asynchronous vibration wave type power membrane frame.

Background technique

At present, domestic metallurgy, mining, power generation, coal mining and other industries will continuously produce a large amount of industrial wastewater in the production process. In order to save energy, that is, water resources, reduce production costs, and improve the discharge conditions, reduce the secondary discharge of wastewater. pollution, so the factory wastewater should be utilized. The equipment traditionally used for industrial waste water utilization includes sand filter, fiber filter, walnut skin filter and so on. The common problems of the above various filter equipment are: low filtration efficiency, high maintenance cost, frequent clogging and periodic backwashing, which seriously wastes clean water resources. As far as the sand filter is concerned, the top layer of the sand filter equipment is evenly covered with quartz sand with a thickness of about 1m. The sewage enters the equipment from the upper surface of the quartz sand, and the pollutants are intercepted by the quartz sand, and the clean water flows out from the lower surface of the quartz sand. . After the equipment runs for a short period, the pollutants in the sewage will stay on the upper surface of the quartz sand and accumulate thicker, and at the same time, the pollutants in the sewage will also fill and block the gaps between the quartz sands. At this time, the sewage will not Flowed, the lower surface of the quartz sand can not get clear water to flow out. In order to restore the filtering conditions, a large amount of clean water must be used to wash away and clean the pollutant layer retained on the upper surface of the quartz sand and the blocked pollutants filled between the quartz sand. Repeatedly like this, the equipment operation cost is high, the maintenance is complicated, the production efficiency is low, and clean water resources are wasted. Therefore, for the production needs of the above factories, it is necessary to improve the above filtering equipment to save energy and reduce consumption, and to make the sewage treatment meet the requirements of reclaimed water reuse.

Detailed ways

The utility model's pulsation skipping asynchronous vibration wave type dynamic membrane frame is realized in this way, and is described in detail below in conjunction with the accompanying drawings. See Fig. 1, Fig. 2, Fig. 3, the pulsation skipping asynchronous vibration wave type power membrane frame is composed of: mounting flange 1, vibrating diaphragm Ⅰ 2, vibrating diaphragm Ⅱ 3, lower sealing plate 4, installation guide post 5 , fixed nut 6 and clear water chamber 7, the vibrating diaphragm Ⅰ 2 and vibrating diaphragm Ⅱ 3 are arranged between the mounting flange 1 and the lower sealing plate 4, and are fixedly connected to form a rectangular box by installing the guide post 5 and the fixing nut 6 Asana structure, with clear water chamber 7 in the middle.

The thickness ratio of diaphragm I 2 and diaphragm II 3 is 2:3.

When the sewage enters the clean water chamber 7, the macromolecular pollutants in the sewage are intercepted through the gap between the vibrating diaphragm Ⅰ 2 and the vibrating diaphragm Ⅱ 3, so that the pollutants in the sewage remain on the outer surface of the box to form a filter membrane . The sewage passes through the filter membrane and then flows into the clear water chamber 7 through the gap between the vibrating diaphragm I 2 and the vibrating diaphragm II 3. At this time, the suspended solids in the water chamber 7 have reached the national first-class A discharge standard, that is, SS≤20mg/L. Due to the thickness difference between the vibrating diaphragm Ⅰ 2 and the vibrating diaphragm Ⅱ 3, when the sewage passes through the filter membrane and enters the clean water chamber 7 through the gap between the vibrating diaphragm Ⅰ 2 and the vibrating diaphragm Ⅱ 3 and then flows upwards, due to the clean water chamber 7 The uniform unevenness of the inner wall, when the clear water flows upwards, it will generate uniform vibration, and this vibration will vibrate at the main frequency. Vibration conduction makes vibrating diaphragm I 2 and vibrating diaphragm II 3 vibrate accordingly. Because of the thickness difference between the vibrating diaphragm I 2 and the vibrating diaphragm II 3, the vibration frequency is not synchronous, and this vibration is asynchronous vibration. Due to the action of the main vibration and asynchronous vibration, the pollutants in the sewage that are about to stay on the outer surface of the tank are retained in a multi-dimensional vibration state, thereby ensuring a constant gap and thickness of the pollutants. The gap and thickness are constant, and the filtered water flow rate is also reliably guaranteed. Sewage with pressure enters the clean water chamber 7 from between the vibrating diaphragm I 2 and the vibrating diaphragm II 3. Vibrating diaphragm I 2 and vibrating diaphragm II 3 are assembled by mounting flange 1, lower sealing plate 4 and mounting guide post 5 to form a box with uniform inner and outer walls due to the difference in external dimensions.

The utility model has a pulsating skipping asynchronous vibration wave type dynamic membrane frame, which realizes the retention of pollutants without clogging, and fundamentally changes the condition that the conventional filtration technology requires short periodic backwashing from time to time, that is, it does not need clean water backwashing. As a result, the filtration efficiency is greatly improved, the operating conditions are improved, and clean water resources are saved. The utility model uses the pulsating jumping asynchronous vibration wave type dynamic membrane frame to replace the sand layer in the sand filter, and the water inlet and outlet conditions remain unchanged, thereby realizing no clogging and no clean water backwashing, which reduces operating costs and saves Energy consumption has a wide range of application and promotion value.
