Marsh liquid filter

Abstract

The invention relates to a marsh liquid filter, belonging to the filter equipment. The marsh liquid filter comprises a marsh liquid chamber and a clear liquid chamber which are divided by a filter net and distributed horizontally; the upper end of the marsh liquid chamber is connected with a marsh liquid inlet pipe; the clear liquid chamber is connected with a filtrate output pipe; the invention is characterized in that the filter net and the marsh liquid inlet pipe form an acute angle; the marsh liquid inlet is close to and faces the filter net; the bottom part of the marsh liquid chamber is also connected with a slag liquid outlet pipe. The filter net of the marsh liquid filter is not blocked and has back washing function; and the filter net is a detachable structure and can be selected according to the size of a drip irrigation hole in a drip irrigation system. The marsh liquid filter has long service life and can conveniently adjust the flow rate in the drip irrigation system after being connected with the drip irrigation system.

Description

technical field [0001] The invention relates to the field of filter equipment, in particular to a biogas slurry filter. Background technique [0002] Biogas slurry is generally used as fertilizer in two ways: root flushing and foliar spraying. Because the biogas slurry is viscous and the slag is too large, it needs to be clarified when spraying, and filtered with gauze to prevent the sprayer from being blocked; when the root is applied, it can only be applied with flood water, and cannot be applied by drip irrigation. The above two methods of application are very labor-intensive, and the amount of fertilization is completely controlled by manpower, and the uniformity of fertilization cannot be guaranteed. [0003] Vegetables in existing facilities are equipped with a drip irrigation system, but the residue in the biogas slurry can easily block the drip irrigation holes, and the biogas slurry must be filtered before entering the drip irrigation system. Existing filters gene...

[0003] Vegetables in existing facilities are equipped with drip irrigation systems, but the residue in the biogas slurry can easily block the drip irrigation holes, and the biogas slurry must be filtered before entering the drip irrigation system

Existing filters generally use a filter screen installed between the inlet and outlet, but the biogas slurry is viscous and the slag is too large, and the filter screen is easily blocked, resulting in frequent cleaning, backwashing or replacement of the filter screen
