Abstract

The utility model discloses an aquarium silencer, which comprises an ornamental tank, a big PVC (polyvinyl chloride) tube and a small PVC tube are arranged on the bottom of the ornamental tank, the small PVC tube is arranged in the big PVC tube, moreover, the big PVC tube and the small PVC tube run through the bottom of the ornamental tank and communicate with a filter tank, a silencer is arranged between the big PVC tube and the small PVC tube, the silencer comprises a water level limit ring, a sleeve and spiral flow guide blades, the sleeve is arranged in the water level limit ring, the spiral flow guide blades are fixed between the water level limit ring and the sleeve, the top of the sleeve is provided with at least two notches, the interior of the sleeve is provided with at least two pairs of ribs, and the spiral direction of the spiral flow guide blades is opposite from the direction of a vortex formed by local water flow. The cost of the aquarium silencer can be reduced to one seventh of the original cost, and moreover, the aquarium silencer is free from cleaning and maintenance and is extremely simple to mount and easy to use.

Description

Aquarium muffler

Technical field

The utility model relates to aquarium apparatus field, especially a kind of aquarium muffler.

Background technology

In aquarium filtration system, the water that cylinder body the inside need to be viewed and admired in top flows in the filtration system of bottom and goes to filter, wherein cylinder body link part has two hard PVC pipes to embody this function, smaller one is mainly the water in lower filtering ponds to be transported to top through water pump view and admire cylinder body, and the space major embodiment between pvc pipe and little pvc pipe is that the water that top is viewed and admired in cylinder body flows into bottom filtration system greatly.But can produce strong eddy current according to the power water stream of bottom filtration system water pump through gap between bassoon and tubule time, thereby produce great noise.

Utility model content

The utility model provides a kind of aquarium muffler for above-mentioned deficiency, comprise and view and admire pond, view and admire bottom, pond and be provided with a large pvc pipe and a little pvc pipe, described little pvc pipe is arranged in large pvc pipe, and large pvc pipe and little pvc pipe run through and the bottom of viewing and admiring pond, and be connected with filtering ponds, between large pvc pipe and little pvc pipe, be provided with a muffler;

Described muffler comprises water level limitation circle, pipe box and water conservancy diversion helical blade, described pipe box is located in water level limitation circle, water conservancy diversion helical blade is fixed between water level limitation circle and pipe box, and pipe box top at least has 2 notches, and pipe box inside is at least provided with 2 pairs of fins;

The hand of spiral of described water conservancy diversion helical blade and local current form the opposite direction of eddy current.

The beneficial effects of the utility model are: become instinct to be reduced to original 1/7, and exempt to clean non-maintaining, and install and be simple and easy to and use.

1-views and admires pond, the large pvc pipe of 2-, the little pvc pipe of 3-, 4-muffler, 5-water level limitation circle, 6-pipe box, 7-water conservancy diversion helical blade, 8-notch, 9-fin as shown in the figure.

Embodiment

Disclosed all features in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.

A kind of aquarium muffler as shown in Figure 1, comprise and view and admire pond 1, view and admire 1 bottom, pond and be provided with a large pvc pipe 2 and a little pvc pipe 3, described little pvc pipe 3 is arranged in large pvc pipe 2, and large pvc pipe 2 runs through with little pvc pipe 3 and views and admires the bottom in pond 1 and be connected with filtering ponds, between large pvc pipe 2 and little pvc pipe 3, be provided with a muffler 4, described muffler 4 comprises water level limitation circle 5, pipe box 6 and water conservancy diversion helical blade 7, described pipe box 6 is located in water level limitation circle 5, water conservancy diversion helical blade 7 is fixed between water level limitation circle 5 and pipe box 6, pipe box 6 tops at least have 2 notches 8, and pipe box 6 inside are at least provided with 2 pairs of fins 9, the hand of spiral of described water conservancy diversion helical blade 7 and local current form the opposite direction of eddy current.The utility model is divided into two symmetrical parts at current port for drawdown, at the Zhong Xia mouth of a river, two pvc pipe roads, by one, be divided into two, thereby reduce the lower water speed of lower water in the single lower mouth of a river, tentatively reduced noise, and by water conservancy diversion helical blade, water (flow) direction and generation eddy current direction are formed in the other direction, upset the condition of current formation eddy current, during through water conservancy diversion helical blade, thereby current can produce centrifugal force and flow down along the duct wall in large pvc pipe road, further reduce noise, water level limitation circle is to play the function that limits the water level of viewing and admiring cylinder body, notch is water level limiting value, the secondary guiding gutter being formed by fin and little pvc pipe in water level limiting value, also participate in the decline of current.In the normal situation of current, secondary guiding gutter is as now air and the leading head piece acting in conjunction that formed by water conservancy diversion helical blade of air introducing port, current and air be mixed to form irregular foams mix body, this mixes physical efficiency equilibrium water and flows down the pressure in the process of falling, the noise that elimination causes because suction is excessive, flow into lower filtering ponds, the utility model cost is low, exempts to unpick and wash, and easy installation and removal, is adapted at promoting on market.

The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
