Description

A fully automatic high-efficiency circulation filter

technical field

The utility model relates to the field of sewage treatment industry, which is a full-automatic high-efficiency circulation filter.

Background technique

The filter is to use one or several filter media, under a certain pressure, make the raw water pass through the media to remove impurities, so as to achieve the purpose of filtration. The fillers inside are generally: quartz sand, anthracite, activated carbon, fiber bundles, etc. The filter mainly uses fillers to reduce the turbidity in the water, intercept suspended solids, organic matter, colloidal particles, microorganisms, chlorine smell and some heavy metal ions in the water, and purify the raw water. One of the traditional methods of water treatment. Its working principle is to use the filter material filled in the filter. When the incoming water flows through the filter layer from top to bottom, the suspended solids and viscose particles in the water are removed, thereby reducing the turbidity of the water. The main problems in the actual operation of the existing filter are: the loss of microorganisms in the raw water caused by the inability to realize the internal circulation of the whole process during the debugging stage; the backwashing of the filter, the pipeline is complicated, and the labor intensity is high, and the operator needs to undergo strict training to master it. operate.

Utility model content

In view of the above problems, the utility model aims to provide a fully automatic high-efficiency circulation filter that ensures the microbial content.

For realizing this technical purpose, the scheme of the present utility model is:

A fully automatic high-efficiency circulation filter, including a filter tank, a filter pipe, a circulation pipe, a pressure sensor, a filter water outlet, a sampling port, a discharge port, a filling port and a filter water inlet, and the filter pipe is installed on On the filter tank body, the circulation pipe is arranged between the filter pipes, the pressure sensor is fixed on the pipe connecting the filter water outlet and the filter water inlet, and the filter water outlet and the sampling port are both arranged on the filter tank body The bottom end of the filter tank, and the sampling port is connected to the filter water outlet, the discharge port is arranged under the outer wall of the filter tank body, and communicates with the inside of the filter tank body, and the filling port is fixed on the outside of the filter tank body The upper part communicates with the inside of the filter tank body, and the filter water inlet is arranged on the top of the filter tank body.

Preferably, the filter pipe is in communication with the circulation pipe.

Preferably, a sampling port is provided at the water outlet of the filter.

Preferably, a pressure sensor is provided at the inlet and outlet of the filter.

The utility model arranges a circulation pipe between the filter pipes, and returns the filtered water at the initial stage of commissioning to the regulating pool for secondary treatment, so as to avoid the loss of microorganisms, affect the commissioning effect, and ensure the microbial content in the commissioning process. By setting the pressure sensor at the inlet and outlet of the filter, when the pressure drop of the inlet and outlet water reaches a certain level, the backwash pump will be automatically turned on, and all relevant valves will be automatically opened and closed, without the need for on-site operation by personnel. Through the improvement, the commissioning and operation of the filter is fully automatic, which reduces the labor intensity, and at the same time solves the problem that the water quality is not up to standard due to the loss of microorganisms during the commissioning stage of the sewage station and affects the user's use. A sampling valve is set at the filter outlet to monitor the outlet water quality at any time.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1, a fully automatic high-efficiency circulation filter according to the embodiment of the utility model includes a filter tank body 1, a filter pipe 2, a circulation pipe 3, a pressure sensor 4, a filter outlet 5, a sampling port 6, The discharge port 7, the filling port 8 and the filter water inlet 9, the filter pipe 2 is installed on the filter tank 1, the circulation pipe 3 is arranged between the filter pipes 2, and the pressure sensor 4 is fixed on the connection On the pipeline of the filter water outlet 5 and the filter water inlet 9, the filter water outlet 5 and the sampling port 6 are all arranged at the bottom of the filter tank body 1, and the sampling port 6 is connected to the filter water outlet 5, and the discharge port The feed port 7 is arranged below the outer wall of the filter tank body 1 and communicates with the inside of the filter tank body 1, and the filling port 8 is fixed on the outside of the filter tank body 1 and communicates with the inside of the filter tank body 1. The filter water inlet 9 is arranged on the top of the filter tank body 1 .

Preferably, the filter pipe 2 is in communication with the circulation pipe 3 .

Preferably, a sampling port 6 is provided at the filtered water outlet 5 .

Preferably, the water inlet 9 and the water outlet 5 of the filter are provided with a pressure sensor 4 .

The working principle of the utility model: by setting the circulation pipe 3 between the filter pipes 2, the filtered water at the initial stage of commissioning is returned to the regulating pool for secondary treatment, so as to avoid the loss of microorganisms, affect the commissioning effect, and ensure the microbial content in the commissioning process. By setting the pressure sensor 4 at the inlet and outlet of the filter, when the pressure drop of the inlet and outlet water reaches a certain level, the backwash pump is automatically turned on, and all relevant valves are automatically opened and closed, without the need for on-site operation by personnel. Through the improvement, the commissioning and operation of the filter is fully automatic, which reduces the labor intensity, and at the same time solves the problem that the water quality is not up to standard due to the loss of microorganisms during the commissioning stage of the sewage station and affects the user's use. A sampling valve is set at the filter water outlet 5, so that the water quality of the outlet water can be monitored at any time.
