Abstract

The invention discloses a silica sand filter for water treatment. The middle of a filter tank is of a cylindrical structure. End enclosures are fixed to the upper end and the lower end of the filter tank respectively. An overflow tube of an L-shaped structure is fixed to the side portion of the filter tank. A lower inlet of the overflow tube is communicated with an inner cavity of the lower portion of the filter tank. The upper end of the overflow tube is communicated with an annular water outlet tube. The annular water outlet tube is arranged on the outer side of the upper portion of the filter tank, and is supported and fastened through an annular tube. An effluent stop plate is arranged at the lower inlet of the overflow tube. A 4-8cm gap is formed between the effluent stop plate and the lower inlet of the overflow tube. The effluent stop plate is fixed to the inner wall of the filter tank through a stop plate support. A water inlet tube is mounted at the top of the filter tank. Aninflow stop plate is arranged under the water inlet tube, and is fixed to the inner wall of the filter tank through a support rod. The silica sand filter has the advantages of high stability, good filtration effect and convenience in use.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, and in particular relates to a quartz sand filter for water treatment. Background technique [0002] Waterworks or pure water supply systems often need to remove algae, particles and other sundries in lakes or rivers. Most of the existing technologies use sedimentation for treatment. However, sedimentation tanks occupy a large area and have low treatment efficiency, which is difficult to apply to the field. There are waterworks in the water supply system. [0003] At present, the common equipment used for filtration in pure water manufacturing equipment is mainly quartz sand filter, which generally places quartz sand directly in the quartz sand filter body, and the bottom of the quartz sand is paved with a filter screen, and the filtered water flows from the The lower layer of quartz sand flows out, which will easily lead to blockage of the filter layer after a period of operat...
