Description

Filtration Washing Separator {Washing and filtering separater of filter beded sand}

The present invention relates to a filter sand recycling apparatus for a long filter sand filter paper, in the filter sorting device for sand filter paper (comprising fine sand, coarse sand, fine gravel, coarse gravel), the damper controlled by the valve is coupled At least one filter thread inlet and water inlet are connected to the T and connected to the sand pump inlet by the suction hose, and the sand and pump are pumped by the operation of the sand pump to spray the washing water from the outside toward the screen through the transfer hose. It is a filtration yarn washing sorting device which is put into a rotary aggregate sorter equipped with a sprinkler, and the impurities mixed in the filtration sand by the rotation of the aggregate sorter are flowed into the water and sorted into fine sand, coarse sand, fine gravel, and coarse gravel.

First of all, the water taken from the intake station is drained through the sedimentation basin, the mixed basin, the flocculation basin, the sedimentation basin and the sand filter basin.

Most of the suspended solids are removed from the settling basin and the unremoved suspended solids are removed from the sand filter. In the case of continuous filtration for 1 to 2 days, the filter is clogged with impurities and the filtration layer is not filtered.

At this time, the filtration function is restored by surface washing and backwash washing of the filtration layer, and when the count is accumulated, the layers of coarse gravel, fine gravel, coarse sand, and fine sand are sequentially mixed with each other, resulting in thin layer separation. Impurity mixes to deeper parts and reduces turbidity and chromaticity, resulting in loss of water purification.

Sand filter paper mainly uses sea sand with high silica sand content, and high quality aggregates are consumed in large quantities to replace the filter sand. Therefore, the natural environment for the collection of filter sands is destroyed and transported from the coastal area far away, so the cost of replacing the filter sands is high due to logistics costs.

Therefore, the conventional technology for the reuse of the filter yarns, such as the Republic of Korea Utility Model Registration No. 20-0167949 and Republic of Korea Utility Model Registration No. 20-0167950 and Korea Utility Model Registration No. 20-0167951 as a filter for washing vehicle for mobile vehicles Although it has been proposed, there is a problem that the economical efficiency is lowered because a relatively complicated process and expensive equipment such as a vacuum vehicle, an inclined conveyor, a washing tank, an underwater vibration pump, and a vibration screen are used.

In order to solve the above problems, it is an object of the present invention to provide a device for reducing waste water and having a high efficiency of washing and sorting in a regeneration device of sand filter paper of a water purification plant and a wastewater plant, that is, a washing and sorting device of a filtration company.

In order to achieve the above object, in the filter sorting device of sand filter paper sand (consisting of fine sand, coarse sand, fine gravel, coarse gravel), the suction hose 22 is connected to the T (25) on the other hand Filtration suction inlet 28 is connected to the water inlet 23 and the damper 27 is controlled by the valve 21 and the suction inlet is connected to the end of the suction hose 22 and operated by an electric motor Sand pump (SP) for pumping the water (1) and filter sand (2, 3, 4, 5) at the same time, the sand pump (SP) outlet is connected to the end of the rotary aggregate sorter (10) inlet And the water hose 1 and the filter sand 2, 3, 4, 5 are rotated by a transfer hose 40 which transfers the sand pump SP to the pumping pressure and a separate motor M to drive the transfer hose. The impurity mixed with the filtered sand (2, 3, 4, 5) introduced through the (40) flows into the water and at the same time fine sand (not shown) coarse sand (53) fine gravel (not shown) Rotating with three kinds of screens 11, 12, 13 sorted by 55 and one or more sprinklers 30 for spraying washing water from the outside towards the screens 11, 12, 13. Aggregate sorter (10) is characterized in that the filter yarn washing sorting device.

The operation and the embodiments will be described with reference to the accompanying drawings.

1 is an embodiment of the filter sand washing screening apparatus according to the present invention.

In the drawing, the sand pump (SP) aggregate on the ground is attached (10), but in reality apart from the aggregate selector (10) to install a sand pump (SP) close to the sand filter paper, the suction hose (22) to the inlet of the sand pump (SP) ) Is coupled to the end of the suction hose 22, T (25) is connected to the water suction port 23 is connected to the filter inlet 28, the damper controlled by the valve on the other hand to the filter paper The filter sand suction opening 28 is brought into contact with the filter sand (2, 3, 4, 5).

The discharge pump of the sand pump (SP) is coupled to the end of the rotary aggregate selector 10, the transfer hose 40 is connected to the inlet and operate the sand pump (SP) to filter sand (2, 3, 4, 5) and water (1) is pumped at the same time into the rotary aggregate sorter (10).

At this time, the water pump 1 is adjusted by adjusting the valve 21 of the damper 27 so that the filter sand 2, 3, 4, 5 is not accumulated in the transfer hose 40 in consideration of the discharge pressure of the sand pump SP. The suction of the filter yarns (2, 3, 4, 5) while sucking enough, and when the suction amount of the filter yarns (2, 3, 4, 5) is excessively accumulated in the transfer hose (40) by adjusting the damper (27) Reducing the suction amount of filter sand (2, 3, 4, 5) increases the suction amount of water (1), the clogged filter sand is gradually transferred smoothly.

Impurities mixed in the filter sand (2,3,4,5) are mostly suspended solids that do not settle in the sedimentation basin, and are separated from the filter sand due to the fluidity and mutual collision of the filter sand in the process of being pumped and transported to the sand pump (SP). It is floated in water and fed into the aggregate sorter.

Water 1 and filter sands 2, 3, 4, and 5 introduced into the rotary aggregate separator 10 are separated by particle sizes passing through the holes of the screens 11, 12 and 13, and are below the rotary aggregate separator 10. Sand (not shown), coarse sand (53), fine gravel (not shown), and coarse gravel (55) are sequentially separated and collected in a separate hopper (not shown) through a guide while floating and water flows. Drained.

At least one sprinkler 30 for spraying the washing water toward the screen is installed at one side of the rotary aggregate sorter to prevent the mixing of the filtered sand 2, 3, 4 and 5 by spraying the washing water to secure the fluidity of impurities. In addition, the screens 11, 12, and 13 are washed to increase the sorting efficiency, while the rotary aggregate sorter 10 is rotated by washing the suspended particles separated by friction between the filter yarns 2, 3, 4, and 5 once again. Provide the send function.

In addition, when the spraying amount of the washing water is small, the filter thread is entangled, so that the filter water does not easily go out through the screen.

Water that contains impurities drained from the rotary aggregate sorter 10, that is, waste water may be discharged without clean water without any change in turbidity, and may be discharged without a separate water purification process. Can be.

Filtration sand (53, 55) selected from the rotary aggregate sorter 10 is reused as a high quality sand filter filtration sand (2, 3, 4, 5) by stacking and dehydrating through a transfer conveyor (not shown).

Filters from sand filtration The filters from nature are high in soil and impurities depending on the place and work process, so they are optimized by several repeated backwashing in sand filter paper.

Therefore, the filter sand particles are hardly attached to the filtrate particles by periodic backwashing and sediment layer removal in the sand filter paper. It is reused as a filter sand.

In the above process, when the sediment layer is thick in the rapid filter paper, and the slow filter paper and the waste water treatment plant sand filter paper are discarded by removing a predetermined thickness of the thin sand layer (2) in which the sediment layer and the sediment are mixed in a large amount, thereby reducing the waste water generation and washing. It is economically advantageous to increase the sorting efficiency.

As described above, the present invention provides an economical sand filter paper filter screening apparatus for simple operation, high washing and screening efficiency, and high productivity per unit, thereby reusing existing filter paper when replacing sand filter paper filters. The natural environment due to sand collection has been preserved, and high-quality filter sand is provided, and sand filter paper sand replacement cost is significantly reduced.
