Detailed ways

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

As shown in Figure 1, a high-efficiency grinding plate water recovery device includes a sewage pool 1, the entrance of the water inlet pipe 2 is arranged in the sewage pool 1, and the outlet of the water inlet pipe 2 is connected to the top of the filter box 3, so The water inlet pipe 2 is connected to the pump machine 4, the top of the filter box 3 is provided with a vacuum pump 5, the filter box 3 is provided with a filter device, the bottom of the filter box 3 is connected to the inlet of the water outlet pipe 6, and the outlet pipe 6 Outlet passes into clean water pool 7. The water in the sewage pool 1 enters the filter box 3 through the water inlet pipe 2 under the action of the pump 4, and then the pressure in the filter box 3 decreases under the action of the vacuum pump 5, which can speed up the filtration speed of the wastewater in the filter device, and finally filter After the water enters the clean water tank 7, it can be recycled, and the filtrate in the filtering device can be recovered simultaneously.

In one of the embodiments, the filter device includes a detachable filter cloth 11 bag 8, a support 9 is arranged directly under the filter cloth 11 bag 8, and a filter screen 10 is detachably installed on the support 9 , the filter cloth 11 is laid on the filter screen 10 . The sewage is filtered for the first time through the filter cloth 11 bags 8, and the filter cloth 11 bags 8 are detachable to facilitate the replacement and cleaning of the filter cloth 11 bags 8. After the first filtration of the filter cloth 11 bags 8, the filter cloth 11 Secondary filtration with the filter screen 10 can improve the filtration efficiency, and the use of the filter cloth 11 can facilitate the collection of filtrates, facilitate the recycling of copper particles in the sewage, and improve the economic value of recycling.

In one of the embodiments, the cross section of the bracket 9 is equal to the cross section of the filter box 3 . After the water in the sewage pool 1 is filtered through the filter cloth 11 bag 8 for the first time, it is filtered through the filter screen 10 and the filter cloth 11 for the second time. The cross-section settings of the filter screen 10 and the filter cloth 11 are the same as those of the filter box 3 In this way, it can be ensured that the water after the first filtration can be completely filtered through the filter cloth 11 and the filter screen 10 for secondary filtration.

In one embodiment, the filter cloth 11 has a pore size of 10-15 microns, and the filter cloth 11 has a pore size of 5-10 microns. The main components in the grinding plate water are copper particles, glass fiber filaments and resin, and the economic benefits of glass fiber filaments and resin are low for recycling, and their diameters are smaller than copper particles, so the filter cloth 11 bags 8 are mainly used to filter glass fibers Silk and resin, the filter cloth 11 bag 8 has a pore size of 10-15 microns, which can filter more than 90% of glass fiber filaments and resins, and filter cloth 11 can further strengthen the filtration of glass fiber filaments and resins and can filter more than 98% at the same time Copper particles, the recovery rate of copper particles is high, and the water filtration effect is improved, so that the filtered water can be recycled as clean water, which can greatly reduce industrial water consumption.
