Description

Technical Field

[0001] The invention relates to the field of fish pond feces separation and filtering equipment, in particular to a novel fish pond negative pressure valve-controlled feces separation and collection filter. Background Art

[0002] In the prior art, the fish pond filtration device mainly adopts a combination of physical filtration and biochemical filtration. Physical filtration mostly adopts a textile interception filtration method. The solid waste such as fish feces, food residues and water in the fish pond flows into the filter tank. The textile intercepts the solid waste. The filtered water then passes through the biochemical filtration system and finally returns to the fish pond.

[0003] The defect of the filtration method of textile interception is that solid waste will be constantly broken in the rapidly flowing water. After the waste is washed by the water flow onto the textile that intercepts the waste, it cannot be cleaned in time. It will be constantly washed and broken by the water flow, and finally become a liquid-like state and enter the biochemical filtration system, which not only puts a great burden on the biochemical filtration system, but also leads to poor filtration effect. In addition, the textile needs to be cleaned and replaced frequently by humans. If it is not cleaned in time, it will be blocked, resulting in low filtration effect. In this way, a large number of textiles need to be replaced every year. Manual cleaning and replacement of textiles is water-consuming, time-consuming, and costly, which adds a lot of burden to fish farmers. It also produces a large amount of difficult-to-degrade chemical fiber waste, which is not environmentally friendly. Fish dare not be fed a large amount of food, and it cannot be easily maintained and managed.

[0004] The feces separation device of the existing fish pond filtration system basically uses a water pump to suck water up and then enter the separation and filtration. The feces will be beaten into powder by the high-speed rotating water pump impeller at the moment of passing through the water pump. The powdered feces are difficult to separate, collect and filter.

[0005] Because the fish pond contains a lot of water, but there is only one pipe to suck feces and water, a large flow pump is needed to suck water. As a result, the greater the flow, the faster the water flow, and the flow rate cannot be controlled. The flow rate is too fast, resulting in feces and other things not being well precipitated and separated. The feces are carried away by the water before they are completely precipitated, so the feces separation and collection effect is not ideal, and the filtration effect is poor. Summary of the invention

[0006] The purpose of the present invention is to provide a novel negative pressure valve-controlled feces separation and collection filter for fish ponds, which can better separate solid pollutants such as feces from water, extend the water change time of the fish pond, and save water, electricity, and labor.

[0007] The technical solution of the present invention is:

[0008] A novel negative pressure valve-controlled feces separation and collection filter for fish ponds comprises a fish pond, a feces separation tank, a biochemical filter tank, a feces inhaler, a feces water supply pipe, a water pump, a water purification pipe, a sewage pipe, a separation tank outlet pipe, a water surface inlet device, and a biochemical filter tank inlet pipe. The feces separation tank and the biochemical filter tank are fixedly installed on the ground at the upper end of the fish pond, the lower end of the feces water supply pipe is placed on the bottom wall of the fish pond, the upper end of the feces water supply pipe extends into the feces separation tank, an exhaust pipe is installed at the upper end of the feces separation tank, the water inlet pipe at the upper end of the feces separation tank is connected with the first water outlet pipe at the upper end of the biochemical filter tank through a tee B, a cross pipe, and an elbow in sequence, the other outlet of the tee B is connected with the feces separation tank water outlet pipe, the feces separation tank water outlet pipe is connected with the water surface water inlet and the biochemical filter tank water inlet pipe respectively through a tee A, a water pump is installed on the biochemical filter tank water inlet pipe, the other end of the biochemical filter tank water inlet pipe extends into the biochemical filter tank, the second water outlet pipe at the upper end of the biochemical filter tank is connected to the clean water pipe, the other end of the clean water pipe is connected to the elbow and is placed on the horizontal surface of the fish pond.

[0009] It also includes valve A, valve B, valve C, valve E, valve F, valve H, and valve I. Valve A is installed on the second water outlet pipe of the biochemical filter tank, valve B is installed on the water outlet pipe of the feces separation tank, valve C is installed on the feces water pipe, valve E is installed on the exhaust pipe of the feces separation tank, valve F is installed on the sewage pipe, valve H is installed on the first water outlet pipe of the biochemical filter tank, and valve I is installed on the sewage pipe of the biochemical filter tank.

[0010] Beneficial effects of the present invention:

[0011] 1. The filter of this application has two water inlet pipes, one for sucking feces and water at the bottom of the water, and the other for sucking oil film on the water surface and sewage without solids on the water surface. The two water inlet pipes work separately and cooperate, which does not affect the overall flow required. By connecting the water pump behind the feces separation tank, a negative pressure is formed to suck feces and water into the separation tank, which solves the problem that feces will be crushed into powder by the water pump impeller after passing through the water pump. Through the valve on the inlet and outlet pipes on the feces separation tank, the flow rate of the water inside can be controlled when passing through the feces separation tank, so that the water flow is slowed down. It solves the impact force of the large water flow generated by too large and fast flow rate in the prior art. If the impact force is large, feces cannot be well precipitated and separated. Thereby, the feces can be well precipitated, separated and collected in the prototype state, and can be easily discharged. It greatly prolongs the water change time, reduces the amount of water change, saves water, electricity and labor. A very small water pump can achieve a good filtering effect. No textiles are used to intercept feces as consumables, and chemical waste is eliminated. It is more environmentally friendly and easy to promote and install. Let people realize the joy of easy fish farming.

[0012] 2. The product produced by the present invention has low cost, is easy to promote and install, has better separation effect of solid feces and garbage, better filtering effect, prolongs water change time and reduces water change amount. The operation is simpler and more intuitive. No chemical fabrics are needed at all, and chemical garbage is eliminated. A very good filtering effect can be achieved with a very small water pump. It can save more water, electricity and labor, and no chemical textiles are used as consumables to intercept garbage solids, which is more environmentally friendly. It is easier to achieve easy fish farming. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to solve the above problems, the fish tank filter described in this application is invented. The application is described in detail below in conjunction with the accompanying drawings:

[0028] like Figure 1-3 As shown: a novel negative pressure valve-controlled feces separation and collection filter for fish ponds, comprising a fish pond 1, a feces separation tank 2, a biochemical filter tank 3, a feces inhaler 4, a feces water supply pipe 5, a water pump 6, a clean water pipe 7, a sewage pipe 8, a separation tank outlet pipe 9, a water surface inlet 10, and a biochemical filter tank inlet pipe 11. The feces separation tank 2 and the biochemical filter tank 3 are fixedly installed on the ground at the upper end of the fish pond 1, the lower end of the feces water pipe 5 is placed on the bottom wall of the fish pond, the upper end of the feces water pipe 5 extends into the feces separation tank 2, the upper end of the feces separation tank 2 is installed with an exhaust pipe 12, the upper end of the feces separation tank 2 is connected with the first water outlet pipe 17 at the upper end of the biochemical filter tank 3 through a tee B13, a cross pipe 15, and an elbow 16 in sequence, the other outlet of the tee B13 is connected with the feces separation tank 2 outlet pipe, the feces separation tank 2 outlet pipe is connected with the water surface water inlet 10 and the biochemical filter tank water inlet pipe 11 through a tee A14, a water pump 6 is installed on the water inlet pipe of the biochemical filter tank 3, the other end of the biochemical filter tank water inlet pipe 11 extends into the biochemical filter tank 3, the second water outlet pipe 25 at the upper end of the biochemical filter tank 3 is connected to the clean water pipe 7, the other end of the clean water pipe 7 is connected to the elbow and placed on the horizontal surface of the fish pond. The sewage and water mixed with feces in the fish pond of the present invention enter the feces separation tank 2 and the biochemical filter tank 3 through two pipelines. In this way, the water mixed with feces does not pass through the water pump 6 and will not be broken by the water pump 6, thus solving the problem raised in the background technology.

[0029] It also includes valve A18, valve B19, valve C20, valve E21, valve F22, valve H23, and valve I24. Valve A18 is installed on the second water outlet pipe 25 of the biochemical filter tank, valve B19 is installed on the water outlet pipe 9 of the feces separation tank, valve C20 is installed on the feces upper water pipe 5, valve E21 is installed on the exhaust pipe 12 of the feces separation tank 2, valve F22 is installed on the sewage pipe 8, valve H23 is installed on the first water outlet pipe 17 of the biochemical filter tank 3, and valve I24 is installed on the sewage pipe 8 of the biochemical filter tank 3.

[0030] In order to improve the filtering effect, the current fish pond filtering device increases the flow of the water pump 6, which causes the flowing water to repeatedly impact the filtering textile when using the textile to filter, breaking the feces, and increasing the burden for the subsequent biochemical filtration. When using the feces separator, because the water pump 6 has a large flow rate and a fast flow rate, the feces cannot be well precipitated and is brought into the subsequent biochemical filtration system, which also increases the burden of the biochemical filtration system and has a poor filtering effect. The filter of the present application has two sets of water supply and water inlet pipelines, which directly divide the sewage containing feces and not containing feces in the fish pond into two ways to enter the filter, and valves are installed on each pipeline to control the speed of the flowing water. Especially the feces water pipe 5 is installed with a valve to slow down the water supply speed, which is more conducive to the precipitation of feces in the separation tank and is convenient for discharge.

[0031] like Figure 6 , 8 As shown: the feces separation tank 2 includes an upper cover 26, a sealing ring 27, a tank body connector 28, a knob 29, a tank body 30, an elbow 16, a water pipe 31, and a tank bottom 32. The tank body connector, the tank body, and the tank bottom are sealed and fixedly connected by glue, the upper cover and the tank body connector are sealed by a sealing ring, and the upper cover and the tank body connector are connected by a knob. The tank bottom 32 includes an outer protective cover and an inverted cone-shaped feces sediment body 36 in the protective cover 35, the upper end of the feces sediment body 36 is connected to the upper inner part of the protective cover 35, the lower end of the feces sediment body is connected to the sewage pipe 8, a hole 37 is opened on the side of the feces sediment body, and the lower end of the feces sediment body 36 is connected to the sewage pipe 8, the water pipe 31 passes through the hole 37 on the side of the tank bottom, the upper and lower ends of the water pipe 31 are connected to the elbow 16, the upper elbow is placed in the tank body, the lower elbow is connected to the lower end of the feces drain pipe, and the upper cover is connected to the exhaust pipe.

[0032] like Figure 7 , 8 As shown: the biochemical filter tank 3 includes an upper cover 26, a sealing ring 27, a tank body connector 28, a knob 29, a tank body 30, an elbow 16, a tank bottom 32, a tray 33 and a filter material 34. The tank body connector, the tank body and the tank bottom are sealed and fixedly connected by glue, the upper cover and the tank body connector are sealed by a sealing ring 27, and the upper cover and the tank body connector are connected by a knob. The tank bottom includes an outer protective cover and an inverted conical dirt precipitation body in the protective cover. The upper end of the dirt precipitation body is connected to the upper inner side of the protective cover, and the lower end of the dirt precipitation body is connected to the sewage pipe 8. The dirt precipitation body has a hole on the side, and the elbow passes through the hole on the side of the dirt precipitation body. The lower end of the elbow is connected to the water inlet pipe 11 of the biochemical filter tank, and the upper cover is connected to the exhaust pipe. The tray is placed on the upper end of the conical dirt precipitation body in the protective cover, and the filter material is placed on the tray.

[0033] The feces separation tank of the present application is similar in structure to the biochemical filter tank, the upper cover and the tank body connector are connected in a manner similar to a flange, and are locked around with plastic knobs. The middle of the upper cover is sealed, and the tank body connector is hollow.

[0034] like Figure 12-13 As shown: one end of the feces inhaler 4 is a connecting pipe 41 connected to the feces water pipe 5, and the other end has a longitudinal long hole 42 on the circumference. The diameter of the end of the feces inhaler 4 with the longitudinal long hole 42 is larger than the diameter of the connecting pipe 41.

[0035] like Figure 9-11 As shown: the water surface water inlet 10 is composed of an inner part 101 and an outer part 102, the inner part 101 is placed in the outer part 102, the inner part 101 has a long strip hole 103 on the upper part, and the lower part is an inner tube 104, the outer part 102 has a long strip hole 103 on the upper part, and the lower part is an outer tube 105, and below the outer tube is a bottom tube 106, and the diameter of the bottom tube is smaller than that of the outer tube.

[0036] Before normal operation, water should be added and exhaust should be performed (see attached Figure 2 , 4 ):

[0037] Open valve B19, valve E21 and valve H23, and close valve C20, valve A18 and valve F22 Open the valve I24, open the water pump 6, the water on the top of the pool passes through the water surface inlet 10, the tee A, the water pump 6, enters the biochemical filter tank inlet pipe 11, enters the biochemical filter tank 3, and after the tank body is full of water, passes through the first water outlet pipe 17 of the biochemical filter tank, valve H23, the horizontal pipe 15, the tee B, enters the feces separation tank 2, and starts to fill with water. The valve E21 plays a venting role. When the water in the feces separation tank 2 is full, close the valve E21, and the water passes through the separation tank outlet pipe 9, the tee B13, the valve B19, and the tee A14 to enter the water pump 6. The water starts to circulate in the tank body and the pipeline. At the same time, the air in the original pipeline is discharged from the water surface inlet 10 when passing through the tee A. After the air in the pipeline and the tank body is completely eliminated, the water filling is completed, and the valves C20, valve A18 and valve B19 are opened, and the valve H23 is closed. The entire filter system starts normal circulation and filtration work.

[0038] Normal operation (see attached Figure 3 , 5 )

[0039] Open valve C20, valve A18 and valve B19, close valve E21, valve H23, valve F22 and valve I24, turn on water pump 6, water surface water inlet 10, tee A separation tank outlet pipe 9, tee B, feces separation tank 2, feces water pipe 5, feces suction device 4 to form negative pressure; the water and feces at the bottom of the pool pass through the feces suction device 4 (see attached for details) Fig.12 ,13 ) is sucked in, passes through the feces water pipe 5, and flows into the feces separation tank 2 from bottom to top through the middle valve C20. By adjusting the opening degree of the valve C20, the water flow entering the feces separation tank 2 is slowed down, and the feces are precipitated and fall in the feces separation tank 2. The sewage and precipitated feces at the bottom are discharged regularly through the valve F22 and the sewage pipe 8. The water without solid matter after precipitation passes through the negative pressure generated by the water pump 6 upward through the tee B, valve B19, tee A, and flows into the water pump 6. At the same time, the other end of the tee A is connected to the water surface water inlet 10 floating on the water surface in the pool (see the attached Fig. 9 ) The oil film on the water surface of the pool and the pollutants floating on the water surface, together with the sewage in the pool, are sucked into the tee A together, and the negative pressure formed by the suction force generated by the water pump 6 is sucked into the water pump 6 and flows into the biochemical filter tank 3 through the biochemical filter tank inlet pipe 11. The sewage flows into the biochemical filter tank 3 and is filtered by the filter material. The clean water passes through the valve A18, the clean water pipe 7, and the outlet pipe elbow to be sprayed back to the pool, thus achieving a complete filtering system.

[0040] The novel negative pressure valve-controlled feces separation and collection filter of the fish pond of the present application comprises a negative pressure feces separation and collection tank and a biochemical filter tank installed on the fish pond. A water pump and a pipeline in the fish pond water, and a water surface water inlet. The water pump is connected between the separation tank and the biochemical filter tank. When the water pump is turned on, the separation tank is formed to absorb water under negative pressure, which avoids the feces from being crushed and dissolved when passing through the water pump, and the water flow is controlled by the valve on the pipeline. The water flow entering the separation tank is slowed down to achieve a good sedimentation separation effect. The problem of poor feces separation effect is easily solved. The feces upper water pipe absorbs feces solids from the bottom of the pool. Through the control of the water valve C on the pipeline, the water flow rate entering the feces separation tank can be adjusted to an appropriate slowness to improve the sedimentation separation efficiency. Another water surface water inlet pipe absorbs the oil film on the surface of the water body that does not contain solids. The surface water does not contain pollutants such as solid feces except the oil film. Directly enter the biochemical filter tank for biochemical filtration, and the solid matter and water are separated in the pool. Two sets of water supply pipes jointly supply water to the biochemical filter tank for filtration, which meets the water flow required for overall filtration. Thus, good separation of solid pollutants and good biochemical filtration effects can be achieved. A good filtration effect can be achieved using a very small water pump. The purpose of extending the water change time and reducing the amount of water change is achieved. Maintenance is easier and simpler, and it saves more water, electricity and labor, better saves electricity and water, and no chemical textiles are used to intercept feces, reducing the generation of chemical waste, achieving more environmental protection, and easier to achieve easy fish farming.
