Description

Technical Field

[0001] The present application relates to a sedimentation tank for fish tanks, which is suitable for fish tanks and can precipitate impurities in the fish tanks to reduce the amount of impurities at the filter. Background Art

[0002] In the process of raising ornamental fish, firstly, for the health of the fish, it is necessary to keep the water in the fish tank clean, and secondly, to ensure the ornamental value, it is also necessary to keep the water in the fish tank clean. The main factor affecting the water quality is that the fish food put in will produce pollutants, some of which are insoluble in water, including uneaten feed, feces, etc. If these pollutants are not cleaned and filtered in time, they will adhere to the wall of the tank to form moss, which will accelerate water pollution. Therefore, it is necessary to filter and clean the water in the fish tank regularly or irregularly. The cleaning process mostly uses artificially laid filter materials for physical interception and separation, such as filter cotton, biochemical cotton, etc. However, these fish tank wastes will accumulate more and more on the filter materials, and people need to clean and replace them regularly.

[0003] In the past, frequent manual cleaning was required, such as changing the water and cleaning the filter material on the tank wall. This method is time-consuming, labor-intensive, and water-consuming, and it is difficult to achieve real-time cleaning, resulting in a short water quality retention period and the need for frequent cleaning. Later, with the improvement of living standards and the development of science and technology, filters suitable for fish farming have gradually been accepted by people. They are installed above the fish tank, and the water in the fish tank is pumped to the filter material such as the filter screen inside it through a water pump. After being filtered by the filter material such as the filter screen, the water is circulated back into the fish tank. By installing a filter in the fish tank, impurities in the water can be cleaned in real time. However, its defects are: 1. Since the water inlet under the water surface is usually placed on one side of the bottom of the fish tank and does not move, it will make it difficult to extract impurities on the opposite side, especially the particles that have settled at the bottom of the fish tank, resulting in incomplete cleaning. Although this method can improve the water quality, it is also limited; 2. The waste stays on the filter material for too long and participates in the water circulation of the fish tank. The waste is constantly decomposed and broken into fine particles by the water flow, and has not substantially left the fish tank, and has been producing organic matter, ammonia nitrogen and other components that are harmful to fish; 3. Frequent water changes and cotton washing are required to stabilize the water quality of the fish tank. Especially for medium and large fish tanks, due to the large amount of feeding, more waste is generated, and maintenance is time-consuming and laborious.

[0004] In the prior art, the invention application "A fish feces and particle filtering device for a fish tank" with application number CN202510044105.5 also removes particles in the water by filtering. The disadvantage of this method is that the filter needs to be cleaned regularly, otherwise the above-mentioned technical defects will also occur.

[0005] Therefore, in order to extend the cleaning cycle and ensure water quality, it is necessary to design a sedimentation tank for fish tanks that uses sedimentation to remove most of the solid waste in the water, extend the use cycle of the filter material, and reduce the total amount of waste remaining on the filter material. Summary of the invention

[0006] The purpose of the present application is to propose a sedimentation tank for fish tanks which utilizes a combination of sedimentation and extraction to remove most of the solid waste in the water, thereby extending the service life of the filter material and reducing the total amount of waste remaining on the filter material.

[0007] The present application is implemented as follows: a sedimentation tank for a fish tank comprises a hollow box body with an open upper end, a left water inlet chamber and a right water inlet chamber are separated by a left partition and a right partition on the left and right sides of the box body, a sedimentation chamber is formed between the left water inlet chamber and the right water inlet chamber, a left spoiler port and a right spoiler port are respectively provided at the diagonal positions of the bottom of the left partition and the right partition, a sewage outlet is provided at the center of the bottom surface of the sedimentation chamber, the sewage outlet is connected to a control device for controlling whether the sewage outlet pipe is conductive or not through a sewage pipe, a water inlet pipe connected to the bottom of the fish tank is provided on the outside of the box body, and the water outlet of the water inlet pipe is divided into two paths, which are respectively connected to the left water inlet chamber and the right water inlet chamber.

[0008] An overflow port is provided on the rear wall of the upper part of the sedimentation chamber, and the overflow port is connected to the filter chamber. The bottom surface of the filter chamber is opened and provided with a filter screen.

[0009] A plurality of teeth are evenly arranged at the bottom end of the overflow port.

[0010] The left spoiler opening is opened at the front lower corner of the left bulkhead, and the right spoiler opening is opened at the rear lower corner of the right bulkhead.

[0011] The water inlet pipe is divided into two outside the box body, which are set as a first branch pipe and a second branch pipe. The water outlet of the first branch pipe is connected to the first water inlet pipe set at the upper part of the right water inlet chamber, and the second branch pipe is connected to the second water inlet pipe set at the upper part of the left water inlet chamber.

[0012] The water outlet of the first water inlet pipe is arranged far away from the right spoiler port, and the water outlet of the second water inlet pipe is arranged far away from the left spoiler port.

[0013] A sewage discharge head capable of generating eddy current is inserted in the sewage discharge port, and a lower port of the sewage discharge head is communicated with a sewage discharge pipe.

[0014] The sewage discharge head comprises a hollow shell with two open ends. A fixed axis is arranged in the shell, a concave wheel is sleeved on the fixed axis, and radially distributed water holes are opened on the concave wheel.

[0015] The concave wheel is in the shape of a funnel with an open upper end, and an axial hole is opened at its lowest end. The upper end of the fixed shaft extends into the axial hole, and limiting rings are fixed on the fixed shaft on both sides of the axial hole. The concave wheel rotates between the two limiting rings with the fixed shaft as the axis.

[0016] Due to the implementation of the above technical solution, the present application forms a vortex in the sedimentation chamber through the left partition, the right partition, and the left spoiler port and the right spoiler port respectively provided thereon, so that the solid waste entering the sedimentation chamber can be concentrated to the central sewage outlet, which is convenient for discharging the solid waste from the sewage outlet. At the same time, an overflow port is provided, so that the excess water can flow into the filter chamber after being precipitated in the sedimentation chamber. The teeth at the overflow port can block the solid waste that has not been precipitated from entering the filter chamber. The above technical features ensure that there is no or very little solid waste in the water flow entering the filter chamber, and most of the solid waste is pumped out by the water pump, so that the water quality of the water flow returning to the fish tank is very good, which not only reduces the interception burden of the filter net, increases the use time, but also prolongs the water quality in the fish tank. The present application is generally installed in the previous stage of the fish tank filter as the first physical filtration, and has strong applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0021] Example: Figure 1-4 As shown, the sedimentation tank for a fish tank comprises a hollow box body 11 with an open upper end, a left water inlet chamber 2 and a right water inlet chamber 5 are separated on the left and right sides of the box body 11 by a left partition 3-1 and a right partition 3-3, respectively, a sedimentation chamber 3 is formed between the left water inlet chamber 2 and the right water inlet chamber 5, a left spoiler port 3-2 and a right spoiler port 3-4 are respectively provided at the diagonal positions at the bottom of the left partition 3-1 and the right partition 3-3, a sewage outlet is provided at the center of the bottom surface of the sedimentation chamber 3, the sewage outlet is connected to a control device 8 for controlling whether the sewage outlet pipe 10 is conductive or not through a sewage outlet pipe 10, a water inlet pipe 4 conductive to the bottom of the fish tank is provided on the outside of the box body 11, and the water outlet of the water inlet pipe 4 is divided into two paths, which are communicated with the left water inlet chamber 2 and the right water inlet chamber 5 respectively.

[0022] Furthermore, an overflow port 1-1 is provided on the rear wall of the upper part of the sedimentation chamber 3, and the overflow port 1-1 is connected to the filter chamber 1. The bottom surface of the filter chamber 1 is open and provided with a filter screen 1-2. When the water flow entering the sedimentation chamber 3 reaches a certain water level, it will enter the filter chamber 1 through the overflow port 1-1, and after filtering fine suspended matter through the filter screen 1-2, it will flow back to the water replenishment mechanism of the fish tank, and then be pumped to the fish tank by the water pump in the water replenishment mechanism to complete the cycle.

[0023] Furthermore, a plurality of teeth are evenly arranged at the bottom end of the overflow port 1 - 1 , and the teeth are used to prevent particles that have not been precipitated from entering the filter chamber 1 .

[0024] Furthermore, the left spoiler port 3-2 is opened at the front lower corner of the left baffle 3-1, and the right spoiler port 3-4 is opened at the rear lower corner of the right baffle 3-3, and the left spoiler port 3-2 and the right spoiler port 3-4 are arranged diagonally. The diagonal opening method can allow the water flow entering the sedimentation chamber 3 to enter diagonally in two ways, so that a vortex can be formed in the sedimentation chamber 3, and the vortex can concentrate the particles to the central sewage outlet, so that the particles are discharged from the sewage outlet 12 to the sewage pipe 10.

[0025] In order to further facilitate the collection and discharge of particulate matter to the sewage outlet 12 , a sewage outlet head 21 capable of generating vortex flow may be inserted into the sewage outlet 12 , and a lower port of the sewage outlet head 21 is connected to the sewage pipe 10 .

[0026] like Figure 6 As shown, the sewage head 21 includes a hollow shell with open ends, and the upper end of the shell has an outward-turned upper edge, which overlaps with the prism opening opened in the upper end of the sewage outlet 12. A fixed axis 24 is arranged in the shell, and a cam 22 is sleeved on the fixed axis 24, and radially distributed water holes 23 are opened on the cam 22. When the water flows through the cam 22, it will flow through the water holes 23, thereby driving the cam 22 to rotate. When the cam 22 rotates, it will stir the water flow to form a vortex, so that the water flow in the shell is accelerated to flow downward, forming a vortex at the sewage outlet 12, further improving the effect of absorbing particulate matter near the sewage outlet.

[0027] Furthermore, the concave wheel 22 is funnel-shaped with an open upper end, and an axial hole is opened at its lowest end. The upper end of the fixed shaft 24 extends into the axial hole, and limiting rings are fixed on the fixed shaft 24 on the upper and lower sides of the axial hole. The concave wheel 22 rotates between the two limiting rings with the fixed shaft 24 as the axis.

[0028] Furthermore, the water hole 23 is a water drop-shaped hole, with its tip facing inward, that is, toward the shaft hole side, and the round end facing outward. When water flows through the water hole 23, there will be a certain difference in the flow rate inside and outside, so that the cam 22 can rotate.

[0029] Furthermore, the water inlet pipe 4 is respectively connected to the upper part of the left water inlet chamber 2 and the right water inlet chamber 5 after passing through the water distribution pipe. Specifically, the water inlet pipe 4 is divided into two paths outside the box body 11, which are set as a first branch pipe 6 and a second branch pipe 7. The water outlet of the first branch pipe 6 is connected to the first water inlet pipe 13 set at the upper part of the right water inlet chamber 5, and the second branch pipe 7 is connected to the second water inlet pipe 14 set at the upper part of the left water inlet chamber 2. Of course, according to actual conditions, the water inlet pipe 4 can be divided into multiple paths outside the box body 11 to evenly or unevenly guide the water flow to the left water inlet chamber 2 and the right water inlet chamber 5.

[0030] Furthermore, the outlet of the first water inlet pipe 13 is arranged away from the right spoiler port 3-4, and the outlet of the second water inlet pipe 14 is arranged away from the left spoiler port 3-2. This arrangement allows the water flows entering the left water inlet chamber 2 and the right water inlet chamber 5 to have a certain flow distance, thereby promoting the formation of vortices in the sedimentation chamber 3.

[0031] Furthermore, the control device 8 is a water pump that can be controlled to work at intervals by a time controller 9. The water pump is controlled by the time controller 9 to work once at regular intervals, and the particulate matter concentrated at the sewage outlet is sucked into the sewage pipe 10 for discharge. The control device 8 composed of the time controller 9 and the water pump, and the technical solution for how to realize the intermittent operation of the water pump are prior arts, not the invention of this application, and its specific structure and working principle are not described in detail here.

[0032] When the present application is installed, the bottom sewage outlet of the fish tank is connected to the water inlet pipe 4 of the present application, and then the bottom of the filter chamber 1 of the present application is connected to the return port of the water replenishment mechanism of the fish tank. After setting the working time of the water pump, when the working time is reached, the water pump extracts the water in the sedimentation chamber 3. During the extraction process, the water in the fish tank enters the left water inlet chamber 2 and the right water inlet chamber 5 through the water inlet pipe 4. In this process, the water flow entering the sedimentation chamber 3 forms a vortex, thereby concentrating the solid waste at the sewage outlet, and finally being extracted and discharged by the water pump. After the water pump stops working, the sewage pipe 10 is disconnected and no longer drains outward. At this time, the water in the fish tank continues to enter the left water inlet chamber 2 and the right water inlet chamber 5. After the water level reaches the height of the overflow port 1-1, it enters the filter chamber 1, and after filtering fine suspended matter through the filter screen 1-2, it flows back to the water replenishment mechanism of the fish tank, and is pumped to the fish tank by the water pump in the water replenishment mechanism to complete the cycle.

[0033] like Figure 5 As shown, the bottom sewage outlet of the fish tank 16 is connected to the water inlet pipe 4 of the present application, and then the bottom of the filter chamber 1 of the present application is connected to the water tank arranged below the fish tank 16. The water tank includes a primary buffer chamber 17, a secondary buffer chamber 18 and a water purification chamber 19 arranged from right to left. A circulating water pump 20 is arranged at the bottom of the water purification chamber 19. A fish tank water inlet pipe 15 is installed on the water outlet of the circulating water pump 20, and the drain outlet of the fish tank water inlet pipe 15 is arranged at the upper part of the fish tank 16. A water inlet is provided at the top of the primary buffer chamber 17, and filter cotton is also provided between the water inlet and the filter screen 1-2 of the filter chamber 1. The water filtered by the filter chamber 1 is filtered by the filter cotton and then enters the primary buffer chamber 17 and the secondary buffer chamber 18 in sequence. After further precipitation of suspended matter that may still exist in the water in the primary buffer chamber 17 and the secondary buffer chamber 18, it finally flows into the water purification chamber 19. The water entering the water inlet chamber 19 is very clean after the aforementioned multiple precipitation and filtration. At this point, the circulating water pump 20 can pump water into the fish tank 16 to replenish the water in the fish tank 16, so that the water level in the fish tank 16 is always maintained at a certain height.

[0034] The above technical features constitute the embodiments of the present application, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the needs of different situations.
