Abstract

The utility model relates to a float-type pumping head. The utility model is floated on the liquid surface, and lifts along the liquid surface. The utility model is characterized in that the inner cavity of a float barrel is divided into two mutually symmetrical spaces at least; a sucking tube 2 is positioned on the upper middle or the lower middle of the float barrel 1 and is used for the connecting opening for the pump. The utility model not only can pump the oil on the water surface, but also can pump the clear liquid and the liquid with much deposit after the solid-liquid mixing system is clarified, etc.

Description

Float-type sucking head for pump

The utility model relates to a kind of suction nozzle of pump.

In industry and oil tanker transportation, in order to fish for the oils on the water surface, often adopt the method for portable pump head, not only operate inconvenience but also can bring air in certain amount into, influence speed, and Jiang Shui mixes with oil easily.

The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, and float type pump suction a kind of simple in structure, easy to use, effective is provided.

The utility model is achieved in that suction pipe is positioned at the neutral position of floating drum, and it can be drawn by its top through floating drum, also can be drawn together by its bottom.Have at least two symmetrical empty chambers to be used to regulate the height of suction nozzle in the floating drum at the water surface, make inflow entrance a little less than water surface site, oils on the water surface is entered the mouth from the influent stream that overflows, when liquid pump was worked, the oil supernatant on water class was constantly overflow the influent stream inlet and is taken away and reach the function of suction oils liquid on the water surface.Suction nozzle lifting leading truck and float type suction nozzle gabarit match, float type suction nozzle or fluctuate in leading truck with liquid level.The height of leading truck and liquid level heave amplitude coupling when leading truck allows in behaviour in service, can be omitted.The utility model can also be used for solid-liquid mixing system clarification, above the clear liquid suction, the heavy suction of drilling the more liquid of thing etc.

Now in conjunction with the accompanying drawings example of the present utility model is described as follows:

Fig. 1 is the schematic representation of bipyramid bottom structure;

Fig. 2 is an absorption pipe structure schematic representation on the pipe type;

Fig. 3 is the strong structure schematic representation of suction pipe under the pipe type;

Fig. 4 overflows into absorption pipe structure schematic representation on the formula for periphery;

Fig. 5 overflows into the strong structure schematic representation of suction pipe under the formula for periphery.

Bipyramid bottom structure of the present utility model as shown in Figure 1, its bottom is a double cone shape, cone is an enclosed shape floating drum 1, in the cylindrical shell 1 at least symmetry be separated into two separate being used to and regulate the space of suction nozzle balance, each space of floating drum 1 all is provided with an aperture that is threaded lid that is used for fill material, the cylindrical shell center is provided with the suction pipe 2 of the pump housing, cylindrical shell is stretched out as the interface that connects the pump housing in suction pipe 2 upper ends, suction pipe is passed down through the first layer awl end, be opened on two layers of awl at the end, two layers of awl form pyramidal space between the end, and its peripheral opening-like narrow annular channel studs with the silk screen grid between seam.

Pipe type structure of the present utility model such as Fig. 2, shown in Figure 3, it is the suction pipe of threeway less that unanimity is set in its floating drum, the one head can be downward or upward as with the interface of the pump housing, two is perpendicular and be inclined upwardly at opening in addition.

Periphery of the present utility model overflows into formula structure such as Fig. 4, shown in Figure 5, inflow entrance surround one week of its cylindrical shell and be lower than cylindrical shell suck tube edge can be divided into draw downward or upward as with the interface of the pump housing.

Claims

1, a kind of float type suction nozzle comprises floating drum 1, suction pipe 2, reaches suction nozzle lifting leading truck 3, it is characterized in that floating drum 1 inner chamber is separated into two symmetrical spaces at least; Suction pipe 2 is positioned in the middle of the floating drum 1.

2, float type suction nozzle according to claim 1 is characterized in that suction pipe 2 can draw from floating drum 1 top or bottom.
