Abstract

The utility model relates to a pneumatic filter, which comprises an air pump and an air delivery pipe which is sealed and connected with the air pump. The other end of the air delivery pipe is connected with an air stone which is positioned on the lower part of a filtering pipe. The bottom of the filtering pipe is provided with a through hole which is communicated with a fish bowl, and the upper part of the filtering pipe is provided with a water outlet port. A filtering device is installed on the out part of the water outlet port of the filtering pipe. The utility model has the advantages of simple integral structure and better filtering effect and uses the air pump to replace a diving pump to reduce the manufacturing cost. To lead the water outlet port to always be positioned on the upper part of the water surface of the fish bowl, the filtering pipe is composed by a plurality of single pipes which are sheathed to be convenient for adjusting height.

Description

Pneumatic filter

The utility model relates to a kind of filter that is used to clean fish jar, particularly a kind of Pneumatic filter.

Existing fish jar filter is to adopt immersible pump that water is extracted out; in pump process; the torrent that produces holds fish easily; cause wounding of fish body, or fish scale is torn, influence appreciation effect; immersible pump is in the oxygenation process that draws water; easily the fish excrement in the fish jar, dirt etc. are blended, cause contaminant particlesization, cause new pollution in the fish jar.

It is a kind of simple in structure that the purpose of this utility model is to provide, good filtration effect, and oxygenation is abundant, the Pneumatic filter that current relax.

The purpose of this utility model realizes by following structure: the utility model is a kind of Pneumatic filter, it comprises an air pump and an appendix that is tightly connected with air pump, the appendix other end is connected with a gas stone, gas stone is positioned at the bottom of screen pipe, the screen pipe bottom has the through hole that is communicated with fish jar, screen pipe top has delivery port, in the delivery port outside of screen pipe filter is installed.

When the utility model uses, earlier gas stone is put into the screen pipe bottom, then screen pipe is vertically put into fish jar.Gas stone is the stone that a kind of centre has cavity, a large amount of bubbles can be emitted and produce to air from the aperture of its wall, produce negative pressure like this in the bottom, bottom water is taken to the delivery port place that is higher than the fish jar water surface together with impurity and overflow at the delivery port place, after filter cloth oozes out evenly to around scatter, various impurity all are collected on the filtering layer by filter cloth.The current that the utility model produces in filter process are very steady, can not cause any impact and injury to fish.The utility model utilizes principle of negative pressure, gas is become be filtered liquid support, promptly satisfied the requirement of giving the water oxygenation in the fish jar, reached the purpose at filter cleaning water source again, because the water flows gently and do not have any mechanical agitation, make the utility model can filter bulk impurity, can stop fine impurities again, filter effect is better.The utility model overall structure is simple, and has replaced immersible pump with air pump, has reduced manufacturing cost.In order to make delivery port be positioned at fish jar water surface top all the time, screen pipe is that a plurality of single tubes are sleeved on together, so that adjust height, can extensively promote the use of.

Fig. 1 is the utility model user mode structure diagrammatic cross-sectional view.

Fig. 2 is a screen pipe top structure schematic diagram.

Below in conjunction with drawings and Examples the utility model is further described.

Embodiment:

The utility model as shown in Figure 1, be a kind of Pneumatic filter, it comprises an air pump 1 and an appendix 2 that is tightly connected with air pump 1, appendix 2 other ends are connected with a gas stone 3, gas stone 3 is positioned at the bottom of screen pipe 4, and screen pipe 4 bottoms have the through hole 5 that is communicated with fish jar, as shown in Figure 2, screen pipe 4 upper bottom portion have delivery port 6, in delivery port 6 outsides of screen pipe 4 filter are installed.Described filter is one and is sleeved on the outer filter cloth 7 of screen pipe 4 tube walls.Described screen pipe 4 constitutes for a plurality of single tubes are sleeved on together, and adjacent two pipes are for being slidingly matched.
