Problems solved by technology

[0003] Existing equipment for industrial circulating water aquaculture ponds mainly use biological and chemical technologies to treat nitrite, nitrogen and phosphorus compounds and large particle suspended solids in the water body. The structure of the decontamination device is complicated and the cost is high. It is widely used in occasions where feces and other suspended particles are the mainstay, and rarely has the function of water level adjustment at the same time.

Embodiment Construction

[0015] The technical solutions of the present invention will be further described below through the accompanying drawings and embodiments.

[0016] control figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , an automatic cleaning screen type fish pond cyclone solid-liquid separation and water level control device, comprising a cyclone box 6, a filter screen 9, a water level controller 7, a filter screen scrubber, a sediment deposition box 13, pipelines, and valves, The swirl box 6 is a box-shaped structure, the upper box is cylindrical, and the lower box is conical; the swirl box 6 is provided with a swirl box water inlet 3, and the swirl box water inlet 3 and the swirl box 6 form a The tangential connection makes the incoming water move tangentially in the cavity of the swirl box 6 to form a swirling flow, so that pollutants such as bait and feces in the incoming water sink. Connection, the water in the fish pond communicates with the cavity of the swirl box 6 thro...

Abstract

The invention provides a rotational-flow solid-liquid separation and water level control device capable of automatically cleaning a filter screen and used for a fishpond. The device comprises a rotational flow box, a filter screen, a water level controller, a filter screen scourer, a sediment deposition box, a pipeline and a valve, wherein the rotational flow box is of a box-shaped structure; the filter screen is fixedly mounted at the top end of the rotational flow box and is used for filtering sewage supernate of the rotational flow box; the water level controller comprises a water control box, an insertion pipe and a sensor, the water control box is of an inward-concave cylindrical box type structure and is installed on the upper portion of the rotational flow box in a sealed mode, a cavity of the water control box is isolated from a cavity of the rotational flow box through a filter screen, and the insertion pipe is installed at the bottom of the water control box and moves underwater relative to the water control box to control the water level of the water pool; the sensor is installed on the inner wall of the water control box, and when the filter screen is blocked by pollutants, the filter screen scourer is started to clean the filter screen; and the sediment deposition box is an inverted conical box body and is used for depositing precipitates in the sewage. According to the rotational-flow solid-liquid separation and water level control device capable of automatically cleaning the filter screen and used for the fishpond, residual feeds in the fishpond and excrement cleaning and water level control of the fishpond can be achieved.

Description

technical field [0001] The invention relates to the field of equipment for industrial circulating water aquaculture pools, in particular to a device for swirling solid-liquid separation and water level control in an automatic cleaning filter screen type fish pond. Background technique [0002] The equipment for industrial circulating water aquaculture ponds is a new type of aquaculture model that is currently being vigorously developed and constructed. The equipment is recycled and reused after treating the wastewater generated in the aquaculture ponds. Since the water in the aquaculture pond contains high organic matter such as residual bait and fish feces, the water in the fish pond is cleaned and filtered through the water treatment equipment to ensure the water quality of the aquaculture pond is clear and improve the water quality of the pond water, which plays an important role in fish farming and environmental protection. On the one hand, the equipment for industrializ...
