Rotary type water treatment filter

Abstract

A rotary type water treatment filter comprises a filtering tank holding filter materials in a sealing way and is characterized in that the filtering tank is horizontally and rotatably arranged on a support frame by rotating shafts at two sides; the tank body is internally provided with a vertical filter material baffle wall which partitions the inner chamber of the tank body into a plurality of filter chambers; the rotating shafts are connected with a power plant in a transmission way; the rotating shafts at the two sides are respectively a water inlet pipe and a water outlet pipe which are not communicated with each other; the water inlet pipe is connected with a water distributor arranged on the upper end of a beginning filter chamber; the lower end of the filter chamber is provided with a water collector which is connected with the water distributor at the upper end of the adjacent filter chamber by the water tubes; the lower end of a terminal filter chamber is provided with a water outlet device which is connected with the water outlet pipe. The rotary type water treatment filter completely overcomes the shortcoming of the existing water treatment filter; when one filter cycle is finished to conduct the back washing or regeneration, the filter tank body slowly rotates to cause the filter materials to generate displacement and friction with each other so that the filter materials are cleanly and thoroughly washed; therefore, the rotary type water treatment filter saves water and has high efficiency. A regenerated liquid is used for soaking the filter materials and guarantees that the filter materials agglomerate never owing to accelerating the replacement reaction of the chemical agent and prolongs the service life, and the filter does not change the filer effect.

Description

technical field [0001] The invention belongs to a water treatment device, in particular to a rotary water treatment filter. Background technique [0002] The existing water treatment filter is to seal the filter material in the tank body, pressurize water to pass through the filter material layer forcibly, and intercept or absorb harmful substances in the water through the filter material to achieve the purpose of water filtration. When the water flow reaches a certain level and the filter material intercepts or absorbs harmful substances in the water, the filter will lose its filtering effect. At this time, it is necessary to backwash and / or regenerate the filter material (backwashing is to reverse the flow direction of the filter and add Press and discharge the sewage until it is washed, and the regeneration is to put the chemical agent into the tank to soak the filter material to replace the filter material adsorbent, and then release the chemical agent). The existing wa...

AI Technical Summary

Problems solved by technology

The existing water treatment filters have the following disadvantages: 1. The backwash requires a high flow intensity, which wastes water resources

2. The backwashing of the filter material attached to the tank wall is not thorough enough to form a dead angle, and the filter material agglomerates for a long time, which greatly reduces the filtering capacity of the filter

3. Under the action of long-term water flow pressure, the filter material has a large bulk density, and if it is soaked and replaced with regeneration solution, the reaction is very slow and the efficiency is very low
