Abstract

The utility model relates to a sleeve pipe device for treating water of receptacles for live fishes. The utility model comprises a water inlet pipe 4, an internal sleeve pipe 3, and an outer sleeve pipe 2. The water inlet pipe 4 is arranged in the middle of the internal sleeve pipe 3. The outer sleeve pipe 2 is arranged outside the sleeve pipe 3. The bottom of the outer sleeve pipe 2 is sealing connected with the outer wall of the internal sleeve pipe 3. The top end of the outer sleeve pipe 2 is higher than the top end of the internal sleeve pipe 3. A water inlet hole 1 2 is installed at the lower end of the outer sleeve pipe 2. The utility model has advantages of clear of excrement and fodder residues in the receptacles for live fishes, automatic hold of liquid level balancing, attractive appearance and simple structure. The installation is only needed to open a small hole at the bottom of the receptacles for live fishes and does not influence water tank strength.

Description

Sleeve type device for treating water of receptacles for live fish

Along with the raising of expanding economy and living standards of the people, increasing family, restaurant and commercial department are provided with cultures tank (or fish jar) and is used for aquatic animals such as culturing fish and shrimp, requires in the groove water quality good, pollution-free, and not having has foul.Therefore, in time filter and change the water in the tank.When changing water, can not make liquid level decline in the groove again.

At present, changing the method that water adopted of culturing in the tank generally is to open two holes on tank.An inlet opening, an apopore.Be the control liquid level, also need to control the height of liquid level by the control flow advancing, valve being set in the water return pipeline.The shortcoming of this way is to open two holes on the tank to influence outward appearance, also influences the intensity of tank; Just be difficult to make liquid level to be in poised state for a long time with valve control and regulation water level, operate loaded down with trivial details.If with float-ball type structure control liquid level, but complex structure, and not attractive in appearance.The excreta and the food-residue that the backwater measure can not make the aquatic animals such as fish in the tank that advance of at present used breed tank discharged from tank well, influences the water quality in the breeding trough.

The purpose of this utility model is the problem that exists at present breed tank water inflowing and returning device, provides in one and can keep liquid level automatically, and can thoroughly get rid of the water inflowing and returning device of the breed tank of the excreta of culturing in the water and food-residue.

The utility model is achieved in that the tubular type water inflowing and returning device of culturing the tank cover comprises water pipe 4, inner sleeve 3, outer tube 2.Water inlet pipe 4 is positioned at the middle part of inner sleeve 3, and the upper end delivery port is positioned at the far-end of culturing tank 1, and lower end water inlet and water pump 11 join.Outer tube 2 is positioned at the outside of inner sleeve 3.The bottom of outer tube 2 links to each other with the outer wall sealing of inner sleeve 3.The top of outer tube 2 is higher than the top of inner sleeve 3.The bottom of outer tube 2 has water-feeding hole 12.The lower end of inner sleeve 3 grows the bottom of outer tube 2, and is furnished with seal washer 5, seal washer 6 and nut 7.

During use, the lower end of inner sleeve 3 is inserted in the hole of culturing tank 1 bottom, seal washer 5 and seal washer 6 place the both sides at the bottom of the breed tank respectively, with nut 7 fastening getting final product.

Concentrate inflow filter 9 unlikely flashing for ease of backwater, inner sleeve 3 lower ends are connected to threeway 8.The lower end outlet of threeway 8 is joined with return pipe 9.Place water inlet pipe 4 in the Horizontal Exit of threeway 8, and by 13 sealings of drain plug gasket assembly.

The course of work of the present utility model is: the far-end of the tank 1 of swimming to culture through water inlet pipe 4 pressure after water pump 11 will filter.The water level of culturing in the tank 1 increases gradually, and when liquid level reached inner sleeve 3 overhead heights, unnecessary water along the inwall spilling water, and filtered through return pipe 9 inflow filters 10 from inner sleeve 3.Water purification after the filtration is pressed into by water pump and cultures tank 1.Circulation so repeatedly makes and cultures in the tank 1 sewage and bring in constant renewal in.In cyclic process, culture sewage in the tank 1 by the annular space overflow of water-feeding hole 12 through between internal and external casing of outer tube bottom to inner sleeve 3, therefore, the excreta of breed tank 1 bottom and food-residue etc. can thoroughly be removed, and have guaranteed the water quality in the tank.

The utility model has the advantages that: can keep culturing the level stability in the tank automatically, can thoroughly remove dirts such as excreta in the tank and food-residue.The water inflowing and returning device simple structure, good looking appearance, breeding trough only needs to open a hole in the bottom during installation, does not influence tank intensity.

Inner sleeve 3 and outer tube 2 can be made integral body, also available being threaded, and the method for welding or pressing is connected as a single entity it.Whole bushing type water inflowing and returning device is made of plastic, and also available metal or glass are made.
