Description

Skimmer for purifying sea water aquarium

The present invention relates to a skimmer capable of purifying a seawater aquarium so that the seawater can be continuously used without having to replace the seawater stored in the aquarium.

Recently, the demand for pets due to the development of children's emotions has increased in the home. The number of singles has increased, and the mystery of fish and sea can be tasted to suit the loneliness and human alienation of urban life due to the nuclear family and aging. The number of hobbyists is increasing, and the sea water ornamental fish industry is showing great interest.

Generally, a seawater aquarium is used to preserve the aquarium fish. Inside the aquarium a proper amount of oxygen and temperature seawater should be maintained to allow the aquarium fish to survive for a long time.

However, in the seawater stored in the seawater aquaria, a considerable amount of foreign matter such as floating matters, dissolved organic matter, and excreta of the sea water ornamental fish is accumulated in the bottom of the aquarium and decomposed by the microorganism over time, so that the dissolved oxygen amount of the seawater is exhausted, And ammonium ions are increased to cause toxicity.

Furthermore, the nutrients increase and the water quality of the seawater deteriorates, and thus, many kinds of germs multiply, resulting in the death of the marine ornamental fish.

Therefore, sea water should be replaced periodically to maintain the environment for the survival of the aquarium fish in the aquarium, but frequent replacement of seawater in the inland area is a significant drawback in cost and time.

Accordingly, a skimmer has recently been used as a device for purifying seawater inside an aquarium without replacing the seawater. The skimmer purifies the water quality of seawater by discharging various foreign substances generated inside the aquarium together with bubble.

It is to be understood, however, that the embodiments described below are only for explanation of the embodiments of the present invention so that those skilled in the art can easily carry out the invention, It does not mean anything. In describing various embodiments of the present invention, the same reference numerals are used for components having the same technical characteristics.

1 to 7, a description will be given of a skimmer for aquatic aquarium according to an embodiment of the present invention.

1 to 3, the seawater aquarium cleaning skimmer includes a pump 310, a first chamber 320, a second chamber 340, a third chamber 360, a fourth chamber 380, A first cover 330, a second cover 350, a third cover 370 and a fourth cover 390, and may further include a detachable member 322. The first cover 330, the second cover 350, The chamber, the cover and the desorption member may be made of a synthetic resin material, and in particular, the chamber may be made of a transparent material.

The pump 310 has a water inlet 311 and an air inlet 312 through which water and air can be introduced into one side of the pump 310, And a first outlet 313 formed on the upper side. In this case, the air inlet 312 is formed on the upper side of the water inlet 311, and water and air are simultaneously introduced into the pump 310. An air inlet pipe 312a is connected to the air inlet 312 and an air control valve 312b is connected to the air inlet pipe 312a to control the amount of air to be injected. The amount of air to be regulated by the air control valve 312b can be determined by the amount of bubbles to be filled in the interior of the first chamber 320, which will be described later. For example, when the amount of bubbles is small and the air bubbles remain in the lower portion, a large amount of air is supplied, and when the amount of bubbles is large, air can be supplied in a small amount.

The pump 310 may include a body 314, a cover 316, and a needle wheel 318. The body 314 is provided with a motor (not shown), and a groove 315 is formed in which the needle wheel 318 can be engaged. The cover 316 is coupled to one side of the body 314, and a space portion (not shown) is formed between the cover 316 and the body 314. A water inlet 311 and an air inlet 312 are formed at one side of the cover 316 and a first outlet 313 is formed at an upper side of the cover 316. The needle wheel 318 is inserted into the groove 315 formed in the body 314 and rotated by the motor so that the air introduced into the space inside the body 314 through the air inlet 312 of the cover 316 Is crushed and crushed to produce fine bubbles. The needle wheel 318 is configured in the form of a plurality of projections, and a more detailed description of the needle wheel 318 will be given later.

The first chamber 320 is formed in the shape of a circular tube and has an open top and a bottom open. A first lid 330 is attached to the lower end of the first chamber 320. The first lid 330 includes a first bubble 321 formed through the surface of the first chamber 320 to allow the first discharge port 313 of the pump 310 to be inserted, And has an inlet 332. Accordingly, the water and bubbles discharged to the first outlet 313 of the pump 310 are moved upward through the first bubble inlet 332 of the first cover 330. The first lid 330 has a purified water discharge port 334 penetrating the surface of the first lid 330 so as to be positioned outside the first bubble inlet 332. The purified water in the first chamber 320 is discharged through the first And is discharged downward through the purified water outlet 334 of the lid 330.

The second chamber 340 is mounted inside the first chamber 320 and has a circular tube shape with a diameter smaller than that of the first chamber 320. The lower end of the second chamber 340 is attached to the upper surface of the first lid 330 so that the first bubble inlet 332 of the first lid 330 is positioned within the circumference of the second chamber 340 . The water and bubbles discharged from the pump 310 flow into the second chamber 340 through the first bubble inlet 332 and the second chamber 340 and the first chamber 320 are separated from each other So that the second chamber 340 substantially functions as a reaction chamber. A second lid 350 is attached to an upper end of the second chamber 340. A through hole 352 is formed in the second lid 350 so that water and bubbles in the second chamber 340 can be discharged upward. . The through hole 352 can have a large number of small diameter. In this case, a through hole may not be formed in a portion of the surface of the second cover 350 corresponding to the vertical upper portion of the first bubble inlet 332. If the vertical upper portion of the first bubble inflow port 332 through which water and bubbles flow is blocked, the outflow pressure can be reduced as compared with the case where the bubbles are blown.

When the water and the bubbles in the second chamber 340 are discharged to the through holes 352 of the second cover 350, the water having a specific gravity tends to descend, but the bubbles having a small specific gravity continue to rise, As a result, the water which is cleaned by the bubbles rising by the foreign matter is filled in the space between the outer surface of the second chamber 340 and the inner surface of the first chamber 320, and the purified water outlet 334 of the first lid 330, .

The third chamber 360 is formed in the shape of a circular tube and accommodates only the bubbles that are coupled to the upper side of the second chamber 340 and rise in the second chamber 340, And the contaminated water may be removed after the third chamber 360 is separated from the second chamber 340. To this end, a third lid 370 is attached to the lower end of the third chamber 360, and the third chamber 360 and the third lid 370 are integrally formed.

The third cover (370) is fitted to the upper end of the first chamber (320) and is detachable. A second bubble inlet 372 is formed at the center of the third lid 370. In this case, the bottom surface of the third lid 370 is upwardly buried toward the second bubble inlet 372 in order to allow the bubble to flow into the second bubble inlet 372. The third lid 370 has a lower end formed in a stepped shape, and is coupled by being fitted to the upper end of the first chamber 320 by a stepped portion (not shown).

The fourth chamber 380 is mounted on the inner side of the third chamber 360 and has a circular tube shape having a diameter smaller than that of the third chamber 360. In this case, the lower end of the fourth chamber 380 may be attached to the second bubble inlet 372 of the third lid 370, and the outer diameter of the fourth chamber 380 may be larger than the diameter of the second bubble inlet 372 As shown in FIG. Accordingly, the spaces between the fourth chamber 380 and the spaces between the fourth chamber 380 and the third chamber 360 are divided into sections so that they are isolated from each other. Accordingly, the bubbles flowing through the second bubble inlet 372 continuously flow into the fourth chamber 380 and then are discharged through the upper end of the fourth chamber 380. The discharged bubbles are discharged to the third chamber 360 and the fourth chamber 380. Eventually, the contaminated water is stored in the space between the third chamber 360 and the fourth chamber 380. When the amount of the contaminated water stored in the third chamber 360 increases, the third chamber 360 may be separated from the second chamber 340, the contaminated water may be discarded, and then the second chamber 340 may be coupled to the third chamber 360.

The fourth lid 390 serves to open and close the upper end of the third chamber 360. When the fourth lid 390 covers the third chamber 360, the fourth lid 390 is discharged to the upper end of the fourth chamber 380 The bubble collides with the lower surface of the fourth cover 390 and moves downward to the space between the third chamber 360 and the fourth chamber 380. [

The desorption member 322 is fixed to the outer surface of the first chamber 320 and has an upper engagement portion 324 to which the upper end of the aquarium wall surface can be fitted. The upper coupling portion 324 may be bent in a 'C' shape opened downward.

The process of purifying seawater using the skimmer for purifying seawater aquarium according to an embodiment of the present invention will be described with reference to FIG. First, when seawater flows into the water inlet 311 of the pump 310 and air flows into the air inlet 312, minute bubbles are generated by the needle wheel 318 rotating inside the pump 310. Then, the fine bubbles are introduced into the second chamber 340 through the first outlet 313 and the first bubble inlet 332 together with the water, and rises together with the water inside the second chamber 340 And is discharged through the through hole 352. Thereafter, the water discharged from the second chamber 340 is filled in the first chamber 320, the fine bubble continues to rise, and then the fourth bubble is introduced through the second bubble inlet 372 of the third lid 370, Chamber 380 as shown in FIG. The fine bubbles are then lifted up and discharged from the fourth chamber 380 and then stored in the space between the fourth chamber 380 and the third chamber 360. The fine bubbles stored therein contain a large amount of foreign matter Since the contamination level is high in one state, it can be discarded periodically. The purified water purified in the first chamber 320 is discharged to the lower side of the first chamber 320 through the purified water outlet 334 of the first lid 330 and circulated into the aquarium.

Hereinafter, the needle wheel in the construction of the skimmer for the aquarium of the seawater according to the embodiment of the present invention will be described in further detail. The needle wheel 318 includes a body 318a, a shaft 318b, and a projection 318c as shown in Fig. The body 318a has a disk shape.

The body 318a may be made of a synthetic resin material. A shaft 318b is fixed to the center of the body 318a and a plurality of protrusions 318c protrude from one side of the body 318a.

The shaft 318b is fixed through the center of the body 318a. When the shaft 318b is rotated, the body 318a is rotated together. The shaft 318b may be made of a metal material or a synthetic resin material. A magnet 318e may be coupled to the outer surface of the shaft 318b. The magnet 318e is inserted into the groove of the pump and is supported without being detached. An anti-shake ring 318d may be coupled to one end of the shaft 318b, that is, to one end of the body 318a that penetrates the body 318a.

The projections 318c are formed on the one surface of the body 318a in a plurality of protrusions. The protrusion 318c is formed in a columnar shape, and may be formed in various columnar shapes, for example, a columnar shape. At least one of the protrusions 318c may be configured to include a first protrusion 318c-1 in a cylindrical shape and a second protrusion 318c-2 in a triangular shape, And may include a protrusion 318c-1 and a second protrusion 318c-2.

Here, the first projection 318c-1 protrudes in a cylindrical shape on one surface of the body 318a, and the second projection 318c-2 protrudes in a triangular shape on the upper surface of the first projection 318c-1 . Therefore, since the tip of the second projection 318c-2 is formed to be sharp, the rate of formation of fine bubbles can be increased when the second projection 318c-2 is rotated as compared with the projections having a cylindrical shape.

5A to 5C, the second projection 318c-2 has a right-angled triangular-shaped second-1 protrusion 318c-2a symmetrical to the first protrusion 318c-2 and a second-2 protrusion 318c-2b . The 2-1 protrusions 318c-2a and the 2-2th protrusions 318c-2b have a shape symmetrical with respect to the center of the upper surface of the first protrusion 318c-1 and are in surface contact with each other. In this case, the length of the base of the second protrusion 318c-2a and the protrusion of the second protrusion 318c-2b may be the same as the length of the top surface of the first protrusion 318c-1. -1 The protrusions 318c-2a and the second-2 protrusions 318c-2b are disposed such that the hypotenuses face each other, thereby forming a space between each of the protrusions. Since the space is formed between the tip portions, the rate of formation of fine bubbles upon rotation can be increased as compared with a simple cylindrical shape.

As shown in Figs. 6A to 6C, the second projection 318c-2 includes a second protruding portion 318c-2c and a second-fourth protruding portion 318c-2d, . The second to third protrusions 318c to 2c have a shape of a right triangle in which the vertex where the base and the hypotenuse meet is located at the center of the top surface of the first protrusion 318c-1. The second 2-4 protrusion 318c-2d has a shape of a right triangle symmetrical to the second protrusion 318c-2c with respect to the center of the upper surface of the first protrusion 318c-1, -3 projected on the vertex of the protrusion 318c-2c. A space is formed between the hypotenuses of the second to third protrusions 318c-2c and the second-fourth protrusions 318c-2d. By forming such a space, the rate of formation of fine bubbles can be increased as compared with a simple cylindrical shape .
