Description

Technical Field

[0001] The utility model relates to the technical field of sewage separation, in particular to a water flow separation mechanism and a sewage separator. Background Art

[0002] When fish are raised in an ornamental fish tank, fish feces and excess bait will be deposited in the tank, causing the water in the tank to become turbid and affecting the survival of the fish.

[0003] In order to improve the water quality of the ornamental fish tank, a sewage separator is usually installed in the ornamental fish tank to filter the fish feces and bait in the fish tank, and the filtered water is circulated to the ornamental fish tank through a submersible pump; however, the existing sewage separator generally uses a filter net or filter cotton to filter and separate the water, and the fish feces and bait will be adsorbed on the surface of the filter net or filter cotton. With the use of the sewage separator, the filtering effect of the filter net or filter cotton is reduced, and it needs to be cleaned and replaced, which has a high maintenance cost. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies of the prior art, the utility model provides a water flow separation mechanism and a sewage separator, so as to fully separate fish excrement, bait and other substances in the water body.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] In the first aspect, the utility model provides a water flow separation mechanism, including an inner ring member and an outer ring member coaxially arranged, wherein a plurality of inner baffles and a plurality of outer baffles are respectively distributed along the circumferential direction at intervals, an annular water flow separation zone is provided between the inner baffle tube formed by the inner baffles and the outer baffle tube formed by the outer baffles, an inward baffle channel connected to the water flow separation zone is formed between adjacent inner baffles, and an outward baffle channel connected to the water flow separation zone is formed between adjacent outer baffles. The water flows in the water flow separation area around the outside of the tubular area surrounded by the inner baffles and the inside of the tubular area surrounded by the outer baffles, forming a vortex. Under the action of the pressure difference, the clean water mixed with small particles will turn back inward and enter the inward baffle channel. Under the centrifugal action, the sewage mixed with large particles will flow outward along the outer baffle into the outward baffle channel for further separation, thereby completing the sufficient separation between large particles of fish feces, bait and clean water. Compared with traditional filters or filter cotton, there is no need to clean or replace them.

[0007] Furthermore, the inner baffle and the outer baffle are arc-shaped plates, the bending direction of the inner baffle is the same as the direction of water flow in the water flow separation zone, and the bending direction of the outer baffle is opposite to the bending direction of the inner baffle. The same bending direction of the inner baffle can ensure the flow rate of the water flow around the outer side of the inner baffle tube, thereby maintaining the pressure difference inside the cyclone zone, which is more conducive to the baffle of the clean water of small particles. The reverse bending direction of the outer baffle intercepts and redirects large particles entering the outward baffle channel, thereby ensuring the separation efficiency of the mechanism.

[0008] Furthermore, one end of the outward baffle channel close to the water flow separation zone is an outward inlet, and the other end is an outward outlet, and the direction from the outward inlet to the outward outlet is opposite to the flow direction of the water flow in the water flow separation zone. The reversely arranged outward baffle channel can form a turning channel that is not conducive to the turning of large particles, thereby intercepting large particles at the water flow separation zone and the outward inlet, prompting the formation of secondary separated clean water at the outward outlet, and further improving the purification efficiency.

[0009] Furthermore, the inner ring member and the outer ring member are both multiple and are arranged on the inner baffle plate and the outer baffle plate at intervals along the vertical direction respectively.

[0010] Furthermore, it includes a flow distribution inner tube and a flow distribution outer tube, wherein the flow distribution inner tube is located inside the inner baffle tube, the flow distribution outer tube is sleeved outside the outer baffle tube, and the flow distribution inner tube and the flow distribution outer tube are fixedly installed relative to the inner ring and the outer ring respectively, and a plurality of flow distribution holes are vertically distributed on the tube wall of the flow distribution inner tube and the flow distribution outer tube. The arrangement of the flow distribution inner tube and the flow distribution outer tube can avoid the phenomenon that most of the water flows out from the inner side of the inner baffle tube or the uppermost end of the outer side of the outer baffle tube, thereby improving the utilization efficiency of the entire water flow separation mechanism.

[0011] Preferably, the apertures of the flow distribution holes on the flow distribution inner tube and the flow distribution outer tube increase sequentially from top to bottom.

[0012] In the second aspect, the utility model also provides a sewage separator, including a separation cylinder, an upper partition and a lower partition are installed on the inner side of the separation cylinder for vertically dividing the internal space of the separation cylinder into an outlet confluence bin, an inlet buffer bin and a sedimentation bin, and an outlet pipe, an inlet pipe and a sewage pipe are installed on the outer side of the separation cylinder, which are respectively connected to the outlet confluence bin, the inlet buffer bin and the sedimentation bin. It is characterized in that a water flow separation mechanism is provided in the sedimentation bin, and the inner ring member, the outer ring member and the flow distribution outer pipe of the water flow separation mechanism are fixed on the lower partition member, and a tangential water inlet may be provided on the lower partition member between the inner ring member and the outer ring member, and a water outlet channel for connecting the outlet confluence bin and the sedimentation bin is provided on the lower partition member outside the flow distribution outer pipe, and the flow distribution inner pipe of the water flow separation mechanism passes through the lower partition member and the upper partition member in sequence to be connected with the outlet confluence bin.

[0013] The sewage to be separated from the water inlet pipe enters the water flow separation area of ​​the water flow separation mechanism through the tangential water inlet of the water inlet buffer tank. Under the separation action of the water flow separation mechanism, the clean water enters the water outlet confluence cavity along the water outlet channel above the flow distribution inner tube and the flow distribution outer tube, and is recycled by the water pump. The sewage containing large particles of fish feces and bait is deposited in the sedimentation tank to be discharged using the sewage pipe.

[0014] The beneficial effects of the utility model are as follows: by designing the above-mentioned water flow separation mechanism and sewage separator, the water flow enters the water flow separation mechanism in a swirling direction, and under the pressure difference and centrifugal action of the swirling flow, the small-particle clean water is turned back at the outer edge of the inner baffle plate and enters the inward baffle channel, and the large-particle sewage will flow outward along the outer baffle plate into the outward baffle channel for secondary separation, thereby ensuring the separation efficiency between large-particle fish feces, bait and clean water, and compared with traditional filter nets or filter cotton, there is no need to clean or replace them, and it can also be widely used in the field of industrial sewage treatment.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution in the utility model, the technical solution in the utility model is clearly and completely described below in conjunction with the accompanying drawings. Other embodiments obtained by those skilled in the art without making any creative work should all fall within the protection scope of the utility model.

[0025] like Figure 1-Figure 3As shown, the water flow separation mechanism of the utility model comprises an inner ring member 101 and an outer ring member 102 which are coaxially arranged, and a plurality of inner baffles 103 and a plurality of outer baffles 104 are respectively arranged on the inner ring member 101 and the outer ring member 102 in a circumferential direction, and an annular water flow separation area 5 is provided between the inner baffle tube surrounded by the inner baffles 103 and the outer baffle tube surrounded by the outer baffles 104, and the water flows in the water flow separation area 5 around the outer side of the inner baffle tube and the inner side of the outer baffle tube. The water flows sideways to form a vortex, and an inward baffle channel 6 connected to the water flow separation zone 5 is formed between the adjacent inner baffle plates 103. The clean water with small particles in the water flow separation zone 5 is turned back into the inward baffle channel 6 under the action of the pressure difference. An outward baffle channel 7 connected to the water flow separation zone 5 is formed between the adjacent outer baffle plates 104. The sewage mixed with large particles enters the outward baffle channel 7 under the action of centrifugation for secondary separation, thereby completing the full separation between large particles of fish feces, bait and clean water. In this scheme, Figure 4 As shown in (a), the inner ring 101 and the outer ring are composed of two concentric rings, which can also be formed according to processing requirements, such as Figure 4 As shown in (b), a plurality of arc holes 107 are opened in the circumferential direction in the middle of the solid body of the annular member. The arc holes 107 serve as water inlet parts connected to the water flow separation zone 5. The inner ring part and the outer ring part on both sides of the arc holes 107 constitute the required inner ring member 101 and outer ring member 102.

[0026] Furthermore, the inner baffle 103 and the outer baffle 104 are arc-shaped plates. In order to ensure the flow velocity of water when flowing around the outside of the inner baffle tube (the tubular area surrounded by the inner baffle 103), the bending direction of the inner baffle 103 is the same as the flow direction of water in the water flow separation area 5. At the same time, in order to intercept and redirect large particles entering the outward baffle channel 7, thereby reducing the flow velocity of the large particles and causing them to settle in advance to ensure the separation efficiency of the mechanism, the bending direction of the outer baffle 104 is opposite to the bending direction of the inner baffle 103.

[0027] One end of the outward baffle channel 7 close to the water flow separation zone 5 is an outward inlet, and the other end is an outward outlet. The direction from the outward inlet to the outward outlet is opposite to the flow direction of the water flow in the water flow separation zone 5. The reversely arranged outward baffle channel 7 redirects the large-particle sewage flowing through the outward inlet. At this time, the large particles cannot continue to return in the outward baffle channel 7 due to their reduced speed, and the clean water from the secondary separation is baffled to the outside of the outward outlet along the reversely arranged outer baffle plate 104, and will not be mixed with the water flow in the water flow separation zone 5 again, thereby increasing the clean water flow and avoiding turbulence.

[0028] In order to make the inner baffle 103 and the outer baffle 104 have a certain strength in the direction of water flow, the inner ring member 101 and the outer ring member 102 are both multiple, and are arranged on the inner baffle 103 and the outer baffle 104 along the vertical interval, wherein the top of the inner baffle 103 and the outer baffle 104 are respectively fixed with the first inner ring member 101 and the first outer ring member 102, and the bottom of the inner baffle 103 and the outer baffle 104 are respectively fixed with the last inner ring member 101 and the last outer ring member 102, according to the length of the inner baffle 103 and the outer baffle 104, a certain number of middle inner ring members 101 and middle outer ring members 102 are selected to be fixed in the middle of the inner baffle 103 and the outer baffle 104, preferably, the distance between adjacent inner ring members 101 / outer ring members 102 does not exceed 20cm.

[0029] In order to prevent the particulate matter entering the inward deflection channel 6 / outward deflection channel 7 from being deposited on the inner ring member 101 or the outer ring member 102 below, the inner ring member 101 corresponding to the inward deflection channel 6 and the outer ring member 102 corresponding to the outward deflection channel 7 are provided with an opening 8. In this embodiment, Figure 3 As shown, the opening directions of the opening portions 8 on the inner ring member 101 and the outer ring member 102 are respectively toward the outer side of the inner ring member 101 and the inner side of the outer ring member 102 .

[0030] In order to avoid the phenomenon that most of the water flows out from the inner side of the inner baffle tube (the tubular area surrounded by the inner baffle plate 103) and the uppermost end of the outer side of the outer baffle tube (the tubular area surrounded by the outer baffle plate 104), and to ensure the utilization efficiency of the entire water flow separation mechanism 1, as shown in FIG. Figure 1 and Figure 2 As shown, it also includes a flow distribution inner tube 105 and a flow distribution outer tube 106, the flow distribution inner tube 105 is located on the inner side of the inner deflector tube, and the flow distribution outer tube 106 is sleeved on the outer side of the outer deflector tube, and the flow distribution inner tube 105 and the flow distribution outer tube 106 are fixedly installed relative to the inner ring member 101 and the outer ring member 102 respectively, and a plurality of flow distribution holes 9 are vertically distributed on the tube walls of the flow distribution inner tube 105 and the flow distribution outer tube 106.

[0031] In order to maintain a certain balance in the flow of water entering the inner side of the flow distribution inner tube 105 from the inward deflection channel 6 and the flow of water entering the outer side of the flow distribution outer tube 106 from the outward deflection channel 7, the aperture of each flow distribution hole 9 increases from top to bottom, that is, the water flow speed that first reaches the upper end of the flow distribution inner tube 105 / flow distribution outer tube 106 is fast, and its flow is restricted by the small-aperture flow distribution holes 9, and then the water flow speed that reaches the lower end of the flow distribution inner tube 105 / flow distribution outer tube 106 is slow, and its flow is increased by the large-aperture flow distribution holes 9.

[0032] like Figure 5 and Figure 6 As shown, the sewage separator involved in the present application includes a separation cylinder 2, an upper partition 3 and a lower partition 4 are installed on the inner side of the separation cylinder 2 to vertically divide the internal space of the separation cylinder 2 into an outlet confluence bin 201, an inlet buffer bin 202 and a sedimentation bin 203, an outlet pipe 204, an inlet pipe 205 and a sewage pipe 206 are installed on the outer side of the separation cylinder 2, which are respectively connected to the outlet confluence bin 201, the inlet buffer bin 202 and the sedimentation bin 203, the above-mentioned water flow separation mechanism 1 is arranged in the sedimentation bin 203, the inner ring member 101, the outer ring member 102 and the flow distribution outer pipe 106 of the water flow separation mechanism 1 are all fixed on the lower partition 4, and a tangential water inlet 401 may be provided on the lower partition 4 between the inner ring member 101 and the outer ring member 102, as shown in FIG. Figure 7 As shown, the tangential water inlet 401 is an arc-shaped opening opened along the circumferential direction on the lower partition 4, and a tangential guide plate 402 is provided in the arc-shaped opening. One end of the tangential guide plate is connected to the inner wall of the arc-shaped opening, and the other end of the tangential guide plate is facing the bending direction of the inner deflector 103. In addition, a water outlet channel 10 for connecting the water outlet confluence bin 201 and the sedimentation bin 203 is provided on the lower partition 4 outside the flow distribution outer tube 106, and the flow distribution inner tube 105 of the water flow separation mechanism 1 passes through the lower partition 4 and the upper partition 3 in sequence and is connected with the water outlet confluence bin 201. After the sewage to be separated enters the water inlet buffer bin 202 from the water inlet pipe 205, it enters the water flow separation area 5 of the water flow separation mechanism 1 along the tangential water inlet 401 in a swirling manner, and forms a swirling flow with the water flow direction being A. Under the pressure difference of the swirling flow, the light-weight small-particle clean water returns along the B direction to enter the inward baffle channel 6, and enters the flow distribution inner pipe 105 through the flow distribution hole 9, and reaches the water outlet confluence bin 201 as clean water along the path E. The heavy-weight large-particle sewage, under the action of centrifugation, moves away from the inner baffle plate 103 and enters the outward baffle channel 7 along the C direction. Since the direction from the outward inlet to the outward outlet of the outward baffle channel 7 is opposite to the flow direction of the water, the outer wall of the outer baffle plate 104 forms a contact surface with the large particles, and the large particles collide with the outward baffle plate 104. The clean water decelerates after hitting the outer wall of the flow plate 104 and cannot complete the return movement in the outward baffle channel 7. It settles in the water flow separation zone 5 and the outward entrance of the outward baffle channel 7, and finally falls to the bottom of the sedimentation bin 203. The clean water after the large particles are settled returns along the D direction in the outward baffle channel 7 and reaches the outward outlet of the outward baffle channel 7, and enters the area between the flow distribution outer tube 106 and the separation cylinder 2 through the flow distribution hole 9, and flows upward into the outlet confluence bin 201 as clean water. Under the action of the inward baffle channel 6 and the outward baffle channel 7, the sewage separator forms two clean water areas on the inner side of the tubular area surrounded by the inner baffle plate 103 and on the outer side of the tubular area surrounded by the outer baffle plate 104, thereby increasing the flow rate of clean water flowing into the outlet confluence bin 201.

[0033] In this embodiment, in order to improve the aggregation effect of the sedimentation bin 203 on large particles of fish feces, bait, etc., the bottom of the sedimentation bin 203 is arranged in a funnel shape.

[0034] like Figure 8 As shown, the sewage separator of the utility model is applied to an ornamental fish tank 11, and is installed in a sewage separation tank 12 on one side of the ornamental fish tank 11. A drain pipe 13 is provided at the bottom of the ornamental fish tank 11 away from the sewage separation tank 12. The outlet end of the drain pipe 13 is connected to the water inlet pipe 205 of the sewage separator. The sewage containing fish feces and bait in the ornamental fish tank 11 enters the sewage separator along the G direction. After the sewage is separated by the water flow separation mechanism 1 in the sewage separator, the sewage containing large particles flows out through the sewage discharge pipe 206 at the bottom of the sedimentation bin 203 and is stored in the sewage collecting tank 15. The clean water containing small particles is discharged into the sewage separation tank 12 from the outlet pipe 204 on one side of the outlet confluence bin 201. In addition, the sewage collecting tank 15 is also provided with a horizontal Balance pipe 17, as the large particles (fish feces, bait) with larger specific gravity in the sewage collecting tank 15 increase, the water entering the sewage collecting tank 15 later will increase the pressure in the sewage collecting tank 15. At this time, the relatively clean water in the upper part of the sewage collecting tank 15 will enter the sewage separation tank 12 through the balance pipe 17 to reduce the pressure of the sewage collecting tank 15, so that the subsequent sewage can enter the sewage collecting tank 15; the submersible pump 14 in the sewage separation tank 12 is used to pump the separated clean water in the sewage separation tank 12 into the ornamental fish tank 11, and form an F-direction ocean current in the ornamental fish tank 11, thereby completing the separate filtration of the water body in the ornamental fish tank 11. Compared with the prior art, the separation efficiency is high, and there is no need to clean and replace the internal mechanism. It only needs to discharge the large particles in the sewage collecting tank 15 regularly through the sewage discharge valve 16.
