Abstract

The utility model relates to an oxygen increase pump for circulating water, and the oxygen increase pump for circulating water is an aquaculture mechanical oxygen increase device by which the sufficient convective circulation of the upper and the lower layers of cultivation water and the circulating flow of an integral cultivation water area can be formed. The oxygen increase pump for circulating water is especially suited to be used by the eel cultivation industry and is also suited to be used in other aquaculture industries. The utility model is characterized in that a vertical axial flow pump is arranged, and the external end of the yielding water room of the vertical axial flow pump is connected with a slanting flow table to make the water of a lower layer pumped upward aslant flowed to a cultivation water surface without pressure. Compared with the existing water surface mixing type and the spaceward water-jet type oxygen increase devices, the utility model has the advantages of high oxygen increase efficiency, good oxygen increase effects, simple structure, etc.

Description

Oxygen-richening pump for circulating water

The utility model belongs to a kind of oxygen increasing pump of water processor machinery device, particularly water circulation type of aquaculture.

The mechanical type oxygen-increasing device of aquaculture at present is common has the water surface to stir and to two kinds of forms of aerial water spray, water surface stirring-type oxygen-increasing device is higher to the oxygenation efficient of surperficial water layer from required equipment and power consumption, but the oxygenation amount of water layer is not easy evenly up and down, the oxygen amount that is difficult to keep whole breed waters is within optimum range, and this just has influence on cultivation density and culture efficiency; Can promote lower layer of water and stir upper water to exhalation air ability of swimming oxygen-increasing device, the laminar flow transmission effect of oxygen is better, but water outlet will pressurize, and lower from required equipment and energy consumption oxygenation efficient, this just causes the raising of aquaculture cost.

The purpose of this utility model provides a kind of oxygenation efficient height, and oxygenation effect is good again, and oxygen-increasing device simple in structure.

The utility model is to realize like this, the water cycle oxygen increasing pump comprises the pump housing by the work of propeller pump principle, axial-flow impeller, be supported in the mechanical driving part that the bearing support assembly on the pump housing is constituted by shaft coupling, transmission shaft with by gusset, keeping a foothold of pump housing bottom, the pump housing water-supplying chamber outer end that is characterised in that of the present utility model is connected to a gutter channel that is in tilted layout.After complete engine set installation is fixing, the water-in of the pump housing is positioned at the lower floor of culturing the waters, after the device (as electric motor or oil engine etc.) that can export swinging moment continuously is installed on above the pump housing, just power is passed to axial-flow impeller by mechanical driving part, rotate with drives impeller, thereby the lower layer of water of culturing the waters is risen to the pump housing water-supplying chamber that is positioned at the water surface for aquaculture top, be raised water then under no pressurized state, tilt to flow to water surface for aquaculture by the gutter channel that is inclined in the water-supplying chamber outer end.Because this method is not have the pressurization water outlet, aquifer yield is big, thus can promote lower layer of water efficiently in a large number, and be formed into the current stirring upper water of thigh, and reaching the abundant convection circulation of levels, it is even that the distribution of dissolved oxygen and water temperature is tending towards; Because this method has the effect of gravitation stream, can bring air into water effectively and the obnoxious flavour in the water is overflowed; Along culturing the pool side edge, can realize the water outlet direction of this device to culture water cycle and flow, hydrostatic is become flowing water, the laminar flow transmission of oxygen and mobile the quickening, so oxygenation effect height of the present utility model, this can make equipment scale and energy consumption reduce, oxygenation effect is relatively good again, and structure is also simple.The utility model is particularly suitable for supporting eel and uses, and the culture fishery that also is suitable for other is used.For the adaptability that makes this device optimum range strong and breed waters oxygen amount is better grasped, the precipitation height of this device and go out water flow velocity adjustable structure should be arranged, the simple method that changes the precipitation height is the tilt adjustable that makes gutter channel, the simple method that changes flow velocity be to current carry out local stop and make block water area and can change.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the longitudinal profile synoptic diagram of a kind of scheme of the utility model.

Fig. 2 is the vertical view of water outlet end of the gutter channel of Fig. 1.

With reference to Fig. 1, the water cycle oxygen increasing pump connects various piece by the pump housing (1), electric motor (2) directly is fixed tightly in the pump housing (1) top by bolt, mechanical driving part is by shaft coupling (3), transmission shaft (5) and form by the bearing support assembly (8) that gusset (9) is supported on the pump housing, electric motor (2) is driven axial-flow impeller (10) rotation by mechanical driving part, be enough to carry the complete machine steady operation and complete machine independently stood on to culture keep a foothold (12) at the bottom of the pond by bolted-on connection in pump housing lower end, gutter channel (7) is articulated in the outer end of the water-supplying chamber (15) of the pump housing (1), gutter channel (7) sidewall is provided with arc groove, the knob (6) that tightens up that passes arc groove is fixed on the certain position gutter channel (7), the flow rate regulation baffle plate (14) that is articulated in gutter channel (7) bottom land can the strut change below it block water area, playing stream increases gas sheet (13) and is riveted on gutter channel (7) water outlet end, with reference to Fig. 2, playing stream, to increase the gas sheet be four, and dewatering cover (4) is fixed in the middle of the shaft coupling to prevent that water from splashing into electric motor (2).

During use, complete machine is laid and is fixed, and at this moment water-in (11) is positioned at the lower floor of culturing the waters, and water directly enters in the pump housing; Unclamp and tighten up knob (6), gutter channel (7) is adjusted to suitable angle of inclination, tighten and tighten up knob (6); Flow rate regulation baffle plate (14) is transferred to suitable height; Send electricity to electric motor (2), axial-flow impeller rotation at this moment, water is promoted to water-supplying chamber (15), is tilted to flow out by gutter channel (7) then; Current are subjected to local the obstruction through flow rate regulation baffle plate (14), flow velocity is with decrease to some degree, current are through gutter channel (7) water outlet end, playing stream at four increases under the gas sheet (13), produce a large amount of foams, the air capacity of water and permitted gas space will increase, and this is to band air entry and make the effusion of breed water obnoxious flavour that positive effect be arranged; The impermeable role of dewatering cover (4) to motor (2) arranged, and the security of electricity consumption is just more guaranteed.
