Abstract

PURPOSE:To remarkably reduce the accumulation of sludge by providing a bottom plate in internal filtering device communicated with the passage holes of the inner partitioning plate in respective rooms and a passage space along the bottom plate between bottom surface of the filter member, thereby prohibiting proliferating configuration of bacteria to be as a filter film type. CONSTITUTION:In the filter medium room (b) flowing-in water from passage hole 6 of inner partitioning plates 3 becomes a forced stream along the bottom plate 4. When the filter member layers are present thereon, bacterias are made to flow out by the dynamic pressure of the stream and lose its functions, thus, an adverse effect by stream is not caused by changing the stream into the bottom passage. The stream is abutted on the wall face 18 and stirred and buffered and made to flow to the passage hole 6' of inner partitioning plate 3, cause rising stream in space layers 8-8'' by the pushing back condition and meanwhile penetrated and dispersed into the filter member 16 and cleaned by the contact with bacteria. In this exemplified case, excelsior type filter member having large passage space is used, so these actions are surely executed. Since the utilization of filter medium having large passage space, partial passage of water is prevented by the buffering action of the bottom passage so convenience utilizing only merits of the filtration medium is obtained.

Description

[Detailed description of the invention] In the conventional vertical filtration tank, the growth form of filtration is in the form of a F film, and therefore the accumulation of activated sludge is large tK. Not only is this easy to cause, but there are also disadvantages due to partial water passage, and filter media with large water passage spaces cannot be used because bacteria are washed away and the filter loses its function. Regarding partial water flow, there is a problem with the flow that occurs at the bottom. Furthermore, cleaning and regeneration requires taking out the appropriate material for F and washing it, and it is very difficult to clean P# again because it is long and thin.

Due to the above reasons, the current situation is that conventional filter tanks are not suitable for use.

This departure F! 4 was created in view of the above, and has a membrane on the bottom plate inside a vertically long cylinder or polyhedron, a water collection chamber on the bottom, and two metal partition plates on the top, so that the inflow chamber and discharge chamber are completely divided. , an internal filtration device in which a pumping pipe for circulation is installed vertically, a space layer is placed in contact with the inlet chamber and the discharge chamber in the flow direction, and a FJM material layer is installed vertically to form a partition filtration layer, and catalytic oxidation is measured. By creating a space between the bottom surface and the bottom plate to create a bottom flow path to provide a buffering effect and an upward flow to the space layer, the form of propagation of snails can be prevented from becoming FP fusuma-like. This is an FA neck mount that eliminates conventional disadvantages, such as preventing water from flowing, making cleaning and regeneration easier, and eliminating the problems caused by flow at the bottom.

The explanation will be given below according to the embodiment. Fig. 1 is a plan view of the P tank cut into rings, Fig. 2 is a @ side view of the Mu person in Fig. 1, and shows the purple bottom plate 4 and the middle partition plate in the main body 1. 3 and 3, inflow chamber a, filtering material layer b, discharge chamber C1 water collection chamber d
A pumping pipe insertion port 5 is opened in the bottom plate 4 of the inflow chamber a, and a pumping pipe 11 is inserted and fixed thereinto to communicate with the water collection chamber d. The filtration material layer communicates with the water inlet 6 provided in the partition 3, and the filtration material layer extending 17" into the partition plate 3.3 has a space layer 8-8 in its flow direction for filtration. Material layers T and T are erected and partitioned, and a bottom flow path 10 is provided along the bottom plate at the threshold between the bottom surface 11 of the filtration material layer T-1 and the bottom plate 4 to form a material passage chamber F. Space layer 8 , the discharge chamber C is connected to the water passage hole 6 provided in the partition plate 3.
A pumping pipe 11 for discharging the discharge chamber eN:f is erected, and the discharge port 12 is connected to the discharge port 13f of the filtration tank main body HC.
Insert 1m and secure. 14 is an air pipe that connects to the air pump, and 15 is a water groove that communicates with the outside and the water collection chamber. FIG. 3 is a perspective view of the seven cylindrical tubes 4w set in the center of a cylindrical aquarium for ornamental fish. Fill all the water up to the pumping pipe outlet 13, water level CL? When the air pump is activated, the water at the bottom of the water tank 1 flows into the water tank 1 through the water flow groove 15 through the water collection pipe 11, and then flows into the water tank from the water discharge pipe 11. Discharge circulates.

As for the effect, since the water surface is small, there is insufficient oxygen dissolution due to contact with the air at the water surface, but the discharge of the pumping pipe is done at the water surface, and the water enters the air during the pumping process. Purified water containing sufficient aqueous fluid is discharged. - 10,000, F suitable material room 1), the pumping pipe V on the inflow side (from
A light amount of oxygen is supplied to the filter bacteria. Father, the benefit of pumping pipes is that the deeper they are, the more water they can lift.

In addition, the pumping pipe can also be circulated only on the discharge side6.
The water flowing into the water inlet 6 of the partition plate 3 flows into a strong flow along the bottom plate 4 at the filter layer shown in FIG. 2 at the sixth knee.

If this flow had a filter material layer there, the dynamic pressure caused by the flow would eat away the bacteria and cause it to lose its function, but in this invention, by changing it to an abrasive flow path, is there any harm caused by the flow? Does not occur. 1 side 1 in the flow
8: The VC collides with the body and moves toward the water inlet 6 of the partition plate 3, but is pushed back and causes a rise fi in the 9-layer 8-8. During this time, the VC penetrates into the filter medium 16 and disperses. Purified by contact with awakening. In this embodiment, the filtering material 16 is made of a wood wool-like material (trade name: Vinylok) with a large water-permeable space, so that its effect is reliably performed. When using a filter medium with a large water passage space, the buffering effect of the bottom flow path prevents water from passing through the υ portion, making it convenient to utilize only the advantages of the filter medium. Even more g! Because it is not upstream or downstream with IJl/i#,
The form of bacterial growth is narrow.

FIG. 4 is a flat rkJ diagram, and is an embodiment in which a rectangular parallelepiped filter Ml chamber is installed in one corner of a circular (capital) water gourd for ornamental fish.

Figure 5 shows a rectangular parallelepiped filtration tank with a wide width and a horizontally long shape.The inflow side partition plate 3 has a water inlet at the bottom, and the discharge side partition plate 3 has a water inlet at the top. The total flow Mk is made to flow through the suction port of pipe 11.11. Arrows indicate water flow. In addition, in this embodiment, a support porous plate 9 for the filter medium is used.
! There is one 1ft outlet side, the inflow g4 is a guide 21, and the filter medium 16i'C with a large water passage space is used.

Figure 6 shows an embodiment in which a step is provided on the bottom surface IT of the filter material layer, and the buffer space is made large to strengthen the buffering effect and at the same time, the upward flow of the space layer 8-8 is strengthened by water flow resistance. I can do it. Note that the filter material 16 is formed by the porous plate 9 and the guide 21
I am trying to support.

According to the present invention, there are far fewer P@-like bacteria in the accumulated sludge, and the sludge does not turn into a konnyaku-like lump, but instead becomes fragile, so cleaning and refurbishment can be done only on the main body of the filtration tank! By pulling out the pumped water '1i11 on the inflow side and washing it completely with tap water, cleaning and regeneration can be done without taking out the FA material.
You can continue using it.

FIG. 7 shows an embodiment in which the bottom channel 10 is blocked by a perforated plate, and F
A suitable support perforated plate 9 is used. The effect is that by completely restricting the water flow, the water flow resistance helps the upward flow to the space layer 8-8 and the buffering effect.

FIG. 8 shows an embodiment in which the flow path space 10 is blocked by partition plates 19 and 19. In the first layer, the i-book space is blocked by the partition plate 19 and the bottom plate 20 of the filter material layer 7, and in the second layer, the i-book space is blocked by the partition plate 19 and the bottom plate 20 of the filter material layer 7. is blocked by a partition plate 19 having a height equal to the height of the flow path space plus the thickness of the filter material,
The dynamic pressure prevents the harmful effects of bacteria being washed away.

As is clear from the above explanation, the interior of the vertically long main body I, which has a small base area and is cylindrical or polyhedral, is
A water collection chamber is formed under the bottom plate, and the water collection chamber communicates with the outside through a water groove, and an inflow chamber and a discharge chamber are separated by a middle partition plate. The filtration material chamber is divided into sections, and the pumping pipe is installed vertically, and the adjacent filtration material chamber is partitioned by installing a filtration material layer vertically through the space layer, and the filtration material of the filtration system used internally is separated. The air flow along the floor plate 15 and the bottom plate 11: By creating a buffering effect and an upward flow to the space layer, it is possible to prevent the growth of bacteria from forming a film. By reducing the accumulated sludge pipe and partially preventing water flow, it is possible to utilize the advantages of a filtration medium with a large water passage space, and at the same time maintaining stable purification power over a long period of time using pumping pipes, etc., it has also made cleaning and regeneration easier. It is an internal filtration device.

Incidentally, the deeper the depth, the more efficient the purifying power can be obtained, so this filter device 1 can be used not only for fish farming but also as other filter devices for frozen fields.
