Embodiment Construction

[0049] Hereinafter, embodiments of the present invention will be described in detail in connection with the accompanying drawings and examples, and the technical contents of the present invention will be more clearly understood.

[0050] Such as Figure 1 ~ 6 As shown in a specific example of the present invention, an automatic reverse rinsing filter includes a tank 1 and a sand filter cartridge 2.

[0051] Such as Figure 1 ~ 3 As shown, the groove body 1 includes a first groove body 11, a first filter plate 141, and a second groove body, and the first filter plate 141 divides the groove body 1 into the upper first groove body 11 and the lower second groove body.

[0052] The first groove body 11 is separated from the left and right partition, and the water pipe 15 is provided in the right partition of the first groove body 11, and the water pipe 15 is "L" shape, including vertical portions. And the horizontal portion: The vertical portion is facing the partition plate 12, and the ...

Abstract

The invention discloses an automatic backwashing filtering device, which comprises a tank body and a gravel filter cartridge. The gravel filter cartridge penetrates through a horizontal cross rod of a fixed support frame and is suspended right above a water outlet pipe arranged in the tank body, the gravel filter cartridge can rotate around the horizontal cross rod under the condition that the gravity center of the gravel filter cartridge is changed, when the filter efficiency is reduced due to the fact that particles intercepted in the gravel filter cylinder are increased, the gravel filter cylinder automatically topples and performs backwashing, and automatically topples to return to the initial position and perform filtering again after backwashing is performed for a period of time, and the steps are repeated, so that filtering and backwashing are performed at the same time, there is no need to interrupt filtering to perform backwashing, and continuous filtration is realized. The device does not need manual control or complex electrical control, and is very simple, low in cost and wide in application range.

Description

Technical field [0001] The present invention belongs to the field of sewage treatment, and in particular, the present invention relates to a backwash filter device. Background technique [0002] Today, in today's water resources, the water pollution is serious, and the comprehensive management of wastewater has become a top priority. Instead of replacing the new water with the treatment, it can reduce the amount of new water, but also reducing the tightness of water resources, but also reduce the amount of waste water, reducing wastewater to the environment. For example, the processed rainwater is used as agricultural irrigation water, and industrial water is used as a circulating water secondary utilization, and domestic sewage and runoff sewage are used as a city water. However, in these wastewater contains some impurities, for example, there is high sand containing water in the northwestern region, and the industrial water is easy to remove and have some solid impurities, such...
