Description

 Filter structure  

The present invention relates to a filter structure, which is mainly designed through the composition of the structure, so that it can better meet the convenience of cleaning and replacing the filter material in addition to the desired water filtration function.

According to the general groundwater or tap water, because the water contains many impurities, heavy metals, sediment and other harmful substances, it is not suitable for direct drinking or use. In order to remove such substances, it is usually necessary to rely on filtration equipment to filter out the substances to obtain a cleaner. Water quality.

According to the existing filtering equipment, the filter material of different particle size and material characteristics is sequentially laid in a predetermined tank space, and an outlet pipe is arranged at the bottom of the tank to introduce the water supply into the tank space from above. After the multi-layer filter material is subjected to layer filtration to remove harmful substances, it is exported from the bottom outlet pipe for use, in other words, the existing filtration equipment usually adopts a top-to-bottom osmosis filtration type.

The above-mentioned filtering equipment can achieve the expected water filtration function, but because it adopts the osmotic filtration mode from top to bottom, the harmful substances filtered are accumulated in the filter material, so every other time The filter material needs to be cleaned or replaced to maintain its filtration efficiency. However, due to the way of filtering the filter material and the filter type, the filter material must be completely removed and cleaned before being re-laid and filled. The entire cleaning process is quite complicated and consumes. At the same time, it is easy to have impurities deposited on the bottom of the tank, which makes it impossible to maintain the cleanliness of the water at the initial stage of re-filtration, seriously affecting the overall practical value, and it is necessary to try to solve the improvement.

In view of the fact that the conventional filtering equipment has extremely troublesome and time-consuming problems in the cleaning operation of the filter material, the inventor specially carries out research and development design, thereby creating a more innovative filter structure.

In the structural design of the invention, the main assembly is provided with a plurality of independent filter cartridges for sequential filling, and the inlet pipe is inserted from the side of the drain pipe connected to the lower part of the bottom of the cylinder and is inserted concentrically into the lower part of the cylinder. At the same time, a water outlet pipe is arranged on the top of the cylinder body to form a reverse osmosis type from bottom to top, so that after the opening and closing valve of the drain pipe is opened, the filter material in the filter cartridge can be directly washed by water from above. Without having to completely remove the filter cartridge, the cleaning time can be greatly reduced, giving better practical convenience.

The filter of the present invention is designed according to the composition of the structure to form a reverse osmosis filtration structure different from the conventional forward osmosis filtration, which not only achieves the desired water filtration efficiency, but also simplifies the cleaning process of the filter material and reduces the cleaning work. At the time, it makes the overall cleaning operation more convenient and practical.
