Silent self-cleaning type completely-automatic solid-liquid separation apparatus

Abstract

The invention discloses a silent self-cleaning type completely-automatic solid-liquid separation apparatus, which comprises an outer shell, a water inlet unit, a filtering and self-cleaning function unit, a motor unit, a water level observation unit and a control unit, wherein the core unit of the apparatus is the filtering and self-cleaning function unit, the filtering and self-cleaning function unit comprises a barrel type filtering screen and a self-cleaning function structure, the self-cleaning function structure is a trickling flow brush type structure, and comprises a trickling flow pipe and a backwashing brush, the backwashing brush is positioned inside the barrel type filtering screen, the brush head portion of the backwashing brush is closely attached to the inner surface of the barrel type filtering screen, and the trickling flow pipe is arranged on the outer surface of the barrel type filtering screen, and is positioned directly above the attaching surface of the brush head and the filtering screen. According to the present invention, when a water body containing solid precipitate flows through the filtering and self-cleaning function unit, the separated filter residue and the trickling flow water body are received in a filter residue groove, and then are discharged in time; the starting or stopping of the self-cleaning function is automatically controlled by the water level sensed by the water level device; and the apparatus can greatly reduce the noise of the machine during the self-cleaning, and is suitable for home, office, hotels, reception and other places requiring low noise or silence.

Description

technical field [0001] The invention relates to the fields of water treatment, aquaculture, and aquarium equipment for ornamental fish, in particular to a silent self-cleaning automatic solid-liquid separation device. Background technique [0002] In water treatment, the removal of precipitable solid matter is an extremely important step. The traditional method is natural precipitation. The disadvantages of natural precipitation: 1) It needs to occupy a large space; 2) It takes a certain amount of time for precipitation and separation, which is not suitable for For flowing water, it is necessary to equip more than two sedimentation spaces, so that the water body in at least one space is in a static state during sedimentation; 3) The sediment is difficult to remove and requires secondary cleaning. Therefore, the solid-liquid separation device that can save a lot of space and speed up the solid-liquid separation speed has been widely used, such as filter screen, sand filter, f...

One of the biggest problems of this type of backwashing is that the impact of high-pressure water on the surface of the filter screen during backwashing will generate a lot of noise. The filter device with an open structure is more noisy, so it is basically not suitable for use in places that require quietness. The places where ornamental fish and aquariums are placed are basically required to be quiet, so other filter devices with low filtering effect and cannot be automatically backwashed can only be used, such as filter cotton, gravel, sand, ceramics, and sedimentation devices, resulting in poor filtering effect and manual cleaning. Filter residue is very troublesome and easy to kill fish

It has caused many similar places to want to raise fish but dare not raise them
