Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture drinking water, and particularly relates to a sterile water filtering device with a backwash structure. Background Art

[0002] In farms, filtering devices are usually used to remove impurities, suspended matter, microorganisms and toxic substances from the water used for aquaculture in order to improve water quality and ensure the growth and health of farmed organisms. These filtering devices usually include different types such as physical filtration, chemical filtration and biological filtration. When using physical filtration, the filter material in the equipment may lose its filtering efficiency due to long-term clogging by impurities, thereby increasing the frequency and cost of maintenance and replacement of filter materials. Secondly, if the filter device cannot be effectively cleaned, the accumulated dirt and impurities will damage the equipment and reduce its service life. Finally, the long-term accumulation of impurities and dirt in the equipment may also breed bacteria and microorganisms, causing water quality deterioration and having a negative impact on the aquaculture environment. Therefore, the filter device should add a backwash structure to avoid problems such as filter material clogging, equipment damage, and water quality deterioration. Therefore, we hope to propose a new structure to solve the above problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a sterile water filtration device with a backwash structure.

[0004] The utility model is realized by the following technical scheme: a sterile water filter device with a backwash structure, comprising: a filter device body, a cleaning brush and a filter mechanism, a filter device base is provided at the bottom of the filter device body, and a filter device top cover is provided at the top of the filter device body;

In actual use, when the device needs to be cleaned, sufficient raw water is injected into the pretreatment chamber through the raw water inlet again, and then the motor is started. The rotation of the motor drives the transmission rod to rotate through the transmission mechanism, and then drives the cleaning brush to rotate. At this time, the horizontal brush brushes the top of the filter mechanism to brush off the dirt on the top of the filter mechanism and disperse it in the raw water.

[0012] As a preferred embodiment, a filter element is provided above the interior of the purification chamber, and two groups of ultraviolet sterilization lamps are embedded on the left and right sides of the purification chamber respectively. The ultraviolet sterilization lamp is connected to an external power supply through a second wire. In actual use, the filter element and the ultraviolet sterilization lamp inside the purification chamber further purify the filtered raw water so that the raw water meets the use standards of sterile water. After the treatment is completed, the sterile water is discharged from the clean water outlet.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: by setting a pretreatment chamber, a purification chamber and a sewage chamber, the raw water can be preliminarily filtered and precipitated inside the pretreatment chamber, and the impurity particles inside the raw water body are blocked inside the pretreatment chamber, avoiding the problems of filter material blockage and equipment damage. The filtered raw water enters the purification chamber for further purification treatment, ensuring the cleanliness of the aquaculture water. By setting a cleaning brush, the dirt accumulated inside the pretreatment chamber and on the top of the filter mechanism can be removed, thereby discharging the dirt from the sewage chamber, ensuring the cleanliness of the inside of the pretreatment chamber, and avoiding frequent maintenance that leads to increased maintenance costs.
