[0002] Liquid water quality improver is a liquid formula product used to improve and maintain the quality of water environment. It usually contains a variety of beneficial ingredients, such as microbial preparations (such as nitrifying bacteria, denitrifying bacteria, photosynthetic bacteria, Bacillus subtilis, etc.), enzyme preparations, nutrients, and possible chemical components. It aims to solve various problems in water bodies. Liquid form of improver is easier to distribute evenly than solid products and can dissolve quickly in water bodies. It is suitable for a variety of water environments, including but not limited to aquaculture, landscape water bodies, industrial wastewater treatment and domestic sewage treatment.

[0003] In the process of water environment management and water quality improver production, efficient filtration is one of the most important links. Traditional filtration systems often have problems such as inconvenient cleaning and frequent filter clogging, which affects production efficiency and water quality. Therefore, the development of a filtration device that can automatically backwash and is easy to maintain is of great significance to improving the overall efficiency of the water quality improver production line. Utility Model Content

[0011] The beneficial effects of the utility model are:

[0012] 1. When in use, the utility model adopts a graded filtration strategy, first removing large particle impurities through a large-aperture filter plate, and then using a cylindrical filter with a smaller aperture to capture fine suspended matter, thereby achieving deep purification of the water body, significantly improving water quality, ensuring the input water quality requirements of the liquid water quality improver production line, and indirectly improving the quality and stability of the final product.

DETAILED DESCRIPTION

[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-3 As shown, a filtering device for a production line of a liquid water quality improver for a water body environment comprises a filter tank, a top cover is installed at the upper end of the filter tank by bolts, a water inlet pipe is arranged on the top cover, a filter plate is arranged at the upper end of the interior of the filter tank, a partition is arranged inside the filter tank, a sewage pipe is arranged on the filter tank, and the sewage pipe is located above the partition, a cylindrical filter screen is arranged on the partition, a water pipe is arranged inside the cylindrical filter screen, a nozzle is arranged at one end of the water pipe, a solenoid valve is installed after the other end of the water pipe passes through the partition, water inlets are symmetrically opened at the connection between the water pipe and the partition, a drain pipe is arranged at the lower end of the filter tank, a valve is arranged on the drain pipe, a water pump is arranged inside the filter tank, and the water pump is located at the lower end of the partition, a water inlet end of the water pump is provided with a pumping pipe, a water outlet end of the water pump is provided with a connecting pipe, and the other end of the connecting pipe is connected to the inside of the water pipe.

[0020] In this embodiment, liquid is first introduced into the filter tank from the water inlet pipe, and the incoming water first flows through the filter plate, where large particles of impurities are initially intercepted. The filtered water continues to flow downward and is subjected to a finer filtration treatment through the columnar filter screen. The aperture of the columnar filter screen is smaller than that of the filter plate, which can effectively block fine suspended matter. The filtered water enters the bottom of the filter tank through the water inlet on the water pipe and is then discharged through the drain pipe. When the columnar filter screen needs to be cleaned, the valve is first closed, the water pump is started, and the water at the bottom of the tank is extracted through the pumping pipe. After pressurization, the water is sent into the water pipe through the connecting pipe. By closing the solenoid valve, the water is ejected from the water inlet and the nozzle on the water pipe, and the columnar filter screen is backwashed. The surface of the filter screen is reversely flushed with high-pressure water flow to effectively remove blockages. During the backwashing process, the cover plate on the sewage pipe is opened, and the impurities flushed down are discharged through the sewage pipe.

[0021] like Figure 1 As shown, flanges are provided on both the water inlet pipe and the drain pipe.

[0022] In this embodiment, the flange-connected water inlet pipe and drain pipe improve the convenience of system assembly and maintenance.

[0023] like Figure 2 As shown, the water inlet end of the water pumping pipe is located above the valve.

[0024] In this embodiment, after closing the valve, the water pump is started to pump water to the bottom of the filter tube into the water pipe.

[0025] like Figure 2 As shown, the pore size of the filter plate is larger than the pore size of the cylindrical filter screen.

[0026] In this embodiment, the filter plate initially intercepts large particles of impurities, and the filtered water continues to flow downward and is subjected to a finer filtration process through the columnar filter.

[0027] like Figure 1 As shown, a cover plate is detachably provided on the sewage pipe.

[0028] In this embodiment, by providing a cover plate, when the cylindrical filter screen needs to be backwashed, the cover plate is opened to allow waste water flushing the cylindrical filter screen to be discharged through the sewage pipe.

[0029] Working principle: First, the liquid enters the filter tank from the water inlet pipe. The water first flows through the filter plate, and large particles of impurities are initially intercepted. The filtered water continues to flow downward and is filtered more finely through the columnar filter. The pore size of the columnar filter is smaller than the filter plate, which can effectively block fine suspended matter. The filtered water enters the bottom of the filter tank through the water inlet on the water pipe and then is discharged through the drain pipe. When it is necessary to clean the columnar filter, first close the valve, start the water pump, and extract the water at the bottom of the tank through the pumping pipe. After pressurization, it is sent to the water pipe through the connecting pipe. By closing the solenoid valve, the water is ejected from the water inlet and nozzle on the water pipe, and the columnar filter is backwashed. The surface of the filter is reversely flushed with high-pressure water flow to effectively remove blockages. During the backwashing process, the cover on the sewage pipe is opened, and the impurities flushed down are discharged through the sewage pipe. The flange-connected water inlet pipe and drainage pipe improve the convenience of system assembly and maintenance.
