Description

an automatic filter

technical field

The utility model belongs to sewage treatment equipment, in particular to an automatic filter.

Background technique

The automatic filter is suitable for water plants of industrial and mining enterprises in rural areas and cities where rivers, lakes, and reservoirs are the water sources. It is an important unit to realize the automatic management of water plants. It integrates sedimentation, sewage discharge, and backwashing, but many existing water purifiers occupy a large area, and backwashing requires electrical equipment such as washing water pumps or air compressors, and comes with manual maintenance costs, which is relatively expensive.

Utility model content

In order to solve the above technical problems, the utility model provides an automatic filter to achieve the purpose of automatic backwashing and improving the efficiency of sewage filtration.

In order to achieve the above object, the technical scheme of the utility model is as follows:

An automatic filter, comprising a tank body, a water inlet pipe 1 is provided on one side of the tank body, a self-priming water distribution bucket 2 is arranged inside the tank body, and the water inlet pipe 1 and the self-priming water distribution bucket 2 connected; the outlet section of the self-priming water distribution bucket 2 is connected with at least two water distribution pipes 3, and the water distribution pipes 3 are all connected to the water inlet end of the filter chamber 4, and the filter chamber 4 is respectively provided with Quartz sand layer 41, pebble filling layer 42, the filter chamber 4 is connected with the drain pipe 5; the side wall of the tank body is also provided with a backwash pipe 7, and the backwash pipe 7 is connected to the The filter chamber 4 communicates.

Further, the top of the self-priming water distribution bucket is provided with an emptying pipe 21 .

Further, the tank body is provided with supporting steel feet 6 .

Further, the backwash pipe 7 is provided with a solenoid valve.

Through the above technical solution, the utility model provides an automatic filter, which is introduced into the filter by a water inlet pipe, and the sewage is divided into several water distribution pipes (at least two) through the self-priming water distribution bucket. The water direction is in contact with the pebble layer and quartz sand layer in their respective filter chambers in turn. The pebble filter material and quartz sand filter material use the gaps between the particles to form a barrier for filtering water quality, allowing water to permeate through and play a role in filtering ;Backwashing is through the electromagnetic valve or regularly into the backwashing pipe, the connecting pipe into the purified water, flushing the clogged material in the filter chamber, and finally discharge the sewage from the drain pipe.

The utility model occupies a small area, separates the space for sewage filtration, and then performs filtration, so the efficiency is higher; the electromagnetic valve is used for backwashing, the process is automated, and the cost of manual maintenance is saved.
