Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of water purification equipment, and in particular relates to a filter material filling device for a V-shaped filter tank. Background Art
[0002] The V-type filter is named because the water inlet grooves on both sides are designed to be V-shaped. During the use of the filter, filter material needs to be laid under the water inlet groove. The general total height of the filter material is 1.25-1.5m. The filter layer is divided into three layers, namely the supporting layer, the supporting layer is gravel, the particle size is 2-4mm, and the thickness is 0.05m. The lower layer uses attapulgite filter material, whose particle size is about 2-3mm, and the filter layer thickness is 0.5m. The lower layer is a homogeneous layer, which is quartz sand filter material, with a particle size of 0.5-1mm and a filter layer thickness of 0.7-0.95m. When in use, after the water passes through the filter material, the removed impurities will accumulate on the surface of the filter material and in the gaps between the particles. As the filter continues to operate, the porosity between the filter materials decreases, affecting the filtration effect, and it is necessary to regularly check the filter material. The filter material is backwashed to remove residual impurities. At present, backwashing is performed by air-water flushing from bottom to top through the filter layer at high speed. The bubbles formed by water vapor pass through the surface of the filter material, and the shear force is increased, so that the dirt that is not easy to peel off on the surface of the filter material is peeled off to achieve the cleaning effect. However, the high shear force of the rapidly rising bubbles will carry away part of the filter material, causing a large amount of filter material loss and increasing the cost of water purification. At the same time, the process of adding filter material is that the construction personnel use a trolley to directly mix and pour a certain proportion of filter material on the upper layer of other filter materials. The added filter material will not only be unevenly distributed in the filter tank, which will not only affect the filtering effect, but also squeeze part of the filter plate on the filter tank, causing the filter plate to deform. Therefore, the existing technology needs further improvement. Summary of the invention
