Problems solved by technology

[0003] In the water treatment process of many industries, due to the relatively large amount of treatment required, the composition of suspended matter in the water is relatively stable, but if traditional pressure filters or vacuum filters are used for treatment, the area occupied by these filtration equipment Relatively large, high operating cost, high water consumption rate for backwashing, and high energy consumption, which does not meet the current requirements for energy saving and consumption reduction

Embodiment Construction

[0015] refer to Figure 1 to Figure 3 , a submerged filter of the present invention, comprising a water storage tank 1, a support frame 2 is arranged in the water storage tank 1, and one or more filter discs 3 are fixedly installed on the support frame 2, and the surface of the filter disc 3 is laid There is a filter medium 4, and the inner cavity of the filter disc 3 communicates with the discharge port 7 through the water outlet pipe 5 and the water pump 6. When working, the water to be treated enters the water storage tank 1 to immerse the filter disc 3 in it. After the water pump 6 is started, the inner cavity of the filter disc 3 forms a negative pressure, and the water to be treated enters the inner cavity of the filter disc 3 through the filter medium 4 to realize filtration. The water is discharged through the outlet pipe 5, the water pump 6 and the discharge port 7. Due to the adoption of the above structure, this submerged filter has a small footprint, low operating...

Abstract

The invention discloses a submerged filter, comprising a water storage tank, a supporting rack arranged inside the water storage tank, one or more filter discs fixedly arranged on the supporting rack, a filter medium arranged on the surface of the filter discs, and an inner cavity of the filter discs which is communicated with a discharge hole by an outlet tube and a water pump. The submerged filter has the advantages of small area occupancy, low operation cost, low water consumption for backwash which only accounts for 0.5%-2.0% of the total filtered water, lower energy consumption which only accounts for 20%-25% of the energy consumption of a conventional pressure filter or a vacuum filter, and meeting the requirements of saving energy and reducing energy consumption.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a filter. Background technique [0002] In the process of solid-liquid separation, filtration technology is one of the most commonly used technologies. The principle of filtration is to form a certain pressure difference on both sides of the filter medium, and the insoluble suspended matter is intercepted by the filter medium to form a filter cake, while the solvent, soluble substances and some particles smaller than the gap of the filter medium can pass through the filter cake and the filter medium to form a clear filter. Filtrate, and then achieve the effect of solid-liquid separation. [0003] In the water treatment process of many industries, due to the relatively large amount of treatment required, the composition of suspended matter in the water is relatively stable, but if traditional pressure filters or vacuum filters are used for treatment, the area occupied by these filtrati...
