Description

Technical Field

[0001] The utility model relates to a sewage treatment device, in particular to a novel sewage treatment filter with cleaning function. Background Art

[0002] Filter filtration is a commonly used water treatment method that uses a variety of media materials to filter impurities in water to improve water quality. Common media are mainly quartz sand, anthracite, activated carbon, yin and yang resins, etc. The quartz sand layer mainly filters larger particles of impurities and suspended matter through screening, while the anthracite layer is mainly used to remove organic matter and chemical substances such as residual chlorine in water; the yin and yang resin mainly removes the corresponding number of ions in water. These media layers are arranged in sequence, and the water flows through each media layer in turn, thereby filtering impurities in the water. Therefore, the filter will continue to accumulate impurities and dirt during operation, which will gradually increase the filtration load and affect the filtration effect. Therefore, the filter material needs to be cleaned every once in a while to remove impurities and dirt accumulated in the media layer.

[0003] At present, the method of cleaning the filter media of multi-media filters used at home and abroad mainly relies on the backwashing of the equipment. This process mainly reverses the direction of the water flow and flushes out the impurities blocked in the medium layer by reverse flushing. However, this method has two serious defects. First, due to the limitation of the equipment body, larger dirt cannot be lifted by the reverse water flow, resulting in incomplete removal of impurities and dirt and insufficient cleaning effect; second, this backwashing method consumes a lot of water and electricity, resulting in increased operating costs. Therefore, it is very beneficial to invent a new type of sewage treatment filter with cleaning. Utility Model Content

[0004] The utility model aims at solving the defects of the existing sewage filter and proposes a novel sewage treatment filter with cleaning function, which can reduce the cleaning times of the filter, has good cleaning effect and can greatly reduce the operation cost.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises a filter (4), the filter (4) is equipped with a double-layer filter material (5), and is characterized in that: an air inlet pipe (6) is installed at the bottom of the filter (4), an air jet pipe (1) is installed at the bottom of the double-layer filter material (5), the air jet pipe (1) is communicated with the air inlet pipe (6), a high-pressure water cleaning pipe (2) is installed at the upper layer of the double-layer filter material (5), the high-pressure water cleaning pipe (2) is connected to a high-pressure water inlet pipe (7) at the middle side of the filter (4), a dirt collection pipe (3) is installed at the middle layer of the double-layer filter material (5), and the dirt collection pipe (3) extends to the outside of the filter (4) and is connected to a drain pipe. The filter (4) is equipped with a water outlet pipe (8) at the bottom and a water inlet pipe (9) at the top.

[0006] The utility model is installed together with the equipment when it is manufactured, and it is a one-time investment with less investment. Compared with the traditional backwashing, the same dirt cleaning, filter material and dirt cleaning can save a lot of water and electricity consumption, and the cleaning effect is better. Therefore, under the same operating conditions, the filter cleaning time interval of the utility model is longer, thereby further reducing energy consumption. Therefore, the filter using this device can achieve the purpose of profit by saving costs as long as it is put into use, and the cost saving during the equipment use period is considerable.

The filter (4) is provided with a water outlet pipe (8) at the bottom and a water inlet pipe (9) at the top.

[0011] During cleaning, the utility model can clean dirt on the filter material through the pressurized water cleaning pipe (2), and remove the dirt through the dirt collecting pipe (3). The dirt on the filter material can also be removed through the jet pipe (1), and the dirt can also be cleaned by backwashing. The cleaning methods are diverse, and the two methods can be used at the same time, so the cleaning effect is good.
