Small circulating filtering device structure for interior of liquid

Abstract

The invention discloses a circulating filtering device structure for the interior of liquid. The structure is externally connected to the bottom of a pump body with a water outlet in the middle-upper side portion through threads, and mainly comprises a threaded connector, a suction barrel, a collecting barrel, an extrusion barrel, a dewatering barrel and an impurity discharging pipe; and also comprises a ring valve, a magnetic suspension track, a rotating track, a conveying crawler belt, and accessory structures and accessories including filter media such as filter discs and filter membranes. The whole structure is externally connected with a pump body and is immersed in an aquaculture water body environment, water containing suspended solid impurities such as excrement and residual bait is sucked into the suction barrel by means of negative pressure of the pump body and is filtered and separated, and purified water is discharged through the pump body; the intercepted impurities are settled by the collecting barrel, dehydrated by the extrusion barrel , formed by glue injection and secondarily dehydrated by the dewatering barrel to form impurity blocks, and the impurity blocks are discharged by the discharging pipe through the conveying crawler belt. The structure does not have the problem of blockage of a filtering medium and does not need to be provided with a backwashing component, and discharged impurity blocks are used as soil fertilizers to be utilized. The structure is simple in component and beneficial to maintenance and repair.

Description

technical field [0001] The invention relates to a structure of a small circulation filter device used inside the liquid, that is, a liquid containing impurities is extracted by means of negative pressure inside the pump body. The structure of the device in which the liquid is circulated. The structure of the device is connected with the pump body through an external screw port and immersed in the liquid, which belongs to the field of liquid impurity removal and purification. Background technique [0002] Circulating water treatment technology is widely used in aquaculture, seawater algae removal, heating, pharmaceuticals, soil washing and purification, meat washing and other fields of industry, agriculture, forestry, animal husbandry, sideline and fishery. The treatment equipment mainly uses the principle of filtration to remove impurities. According to the physical and chemical properties of impurities in the liquid, select the corresponding treatment process and filter me...
