Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] The floating filter material filtering device provided by the present invention comprises: a filter tank 3 with a cavity inside and a water inlet device 2 and a water outlet device 12 arranged thereon. The plate 8 divides the cavity into the water inlet pool 4 with the water inlet device 2 and the water outlet pool 11 with the water outlet device 12. The water inlet pool 4 and the water outlet pool 11 are connected by the overflow port on the partition plate 8 which is lower than the top of the pool. , the outlet pool 11 is provided with a filter material input device 10, the water inlet pool is provided with a filter material output device 6, and the input floating filter material 7 floats on the upper part of the cavity.

[0025] The solid-liquid separation process of the mixed liquid during the operation is as follows: the mixed liquid enters the sedimentatio...

Abstract

The invention provides a floating filter material filter device, which comprises a filter tank provided with a cavity inside and provided with a water inlet device and a water outlet device, and is characterized in that a partition plate is arranged in the cavity of the filter tank and divides the cavity into a water inlet tank with the water inlet device and a water outlet tank with the water outlet device; the water inlet tank and the water outlet tank are communicated through an overflow port lower than the tank top, the water outlet tank is provided with a filter material input pipe, the water inlet tank is provided with a filter material output pipe, and input floating filter materials float on the upper portion of the cavity. Through mutual independence of floating filter material adding, discharging and filtering operation, continuous operation of floating filter material adding, discharging and filtering operation and off-line flushing of the filter material, the precipitation and filtering separation effects of the mixed liquid are greatly improved, and the device has the characteristics of low energy consumption, low investment and operation cost, simplicity in control and management and the like.

Description

technical field [0001] The invention provides a filter device, in particular a floating filter material filter device, which belongs to the technical field of filter equipment design and manufacture. Background technique [0002] Filtration is one of the most commonly used solid-liquid separation technologies. According to the form of filter media, it can be divided into surface filtration and deep filtration. In the deep filtration, granular filter media such as quartz sand, anthracite, activated carbon, and ceramsite are used as filter media. The conventional filtration process includes two parts: filtration and backwashing. Filtration is to intercept the solid phase in the mixed liquid through the filter material, and then discharge the solid phase in the filter material through backwashing to achieve solid-liquid separation. Since backwashing and filtration cannot be carried out at the same time, filtration can only be carried out by means of intermittent operation. At ...
