Description

Technical Field

[0001] The utility model relates to the field of water purification equipment, in particular to a water flow purification device. Background Art

[0002] Water purification is targeted at different occasions. For some circulating water purification occasions, such as fish tank water purification, many factors need to be considered. The traditional purification method includes turnover box filtration purification. The water in the tank must be pumped to the top layer of the turnover box, filtered through the filter cotton layer, biochemical filter material layer, and bacterial house layer, and then discharged back into the tank. Although the turnover box has a strong filtering ability, it also has an upper limit. Its filtering method also determines that granular fish feces accumulate in the filter cotton layer, and then dissolve under the flushing of water flow and re-enter the water body, causing problems such as water acidification. Therefore, the filter cotton layer needs to be replaced or cleaned frequently. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a water purification device with high filtration efficiency, easy cleaning and the ability to effectively reduce blockage and reduce the impact of scouring and dissolution of filtered matter on water quality.

[0004] In response to the above problems, the following technical solutions are provided: a water purification device, comprising a first box body, a second box body, and a third box body stacked in sequence from top to bottom, the first box body, the second box body, and the third box body are each provided with an opening on the top and a filter cavity is formed in the opening, the first box body and the second box body are each provided with evenly distributed water filter holes at the bottom, the first box body is provided with a water inlet pipe, the third box body is provided with a water outlet pipe, and the bottom of the filter cavity of the first box body is laid with filter cotton; a water diversion pipe connected to the water inlet pipe is also provided in the opening of the first box body, the water diversion pipe is horizontally arranged and provided with drip outlets spaced along its length direction, the drip outlets are located in the range of 3 o'clock to 9 o'clock on the cross section of the water diversion pipe; a horizontally arranged wire mesh is provided above the filter cotton; a diversion cone is provided above the wire mesh, which is located below the water diversion pipe, has the same length direction as the water diversion pipe, and has an isosceles triangle cross-section, and the top edge of the diversion cone coincides with the projection of the axis of the water diversion pipe on the wire mesh surface.

[0005] In the above structure, a drip outlet is set in the range of 3 o'clock to 9 o'clock on the cross-section of the water diversion pipe, and is divided into two by the diversion cone when the water flows downward, so that the water flow carries granular fish feces to flush to both sides of the diversion cone. In this process, the water flow changes from vertical movement to inclined and then to horizontal flow, carrying and flushing the fish feces to stop on the wire mesh far away from the position of the diversion cone. The water flow is gradually filtered by the wire mesh during the horizontal flow on the wire mesh. Therefore, the flushing force of the water flow at the position where the fish feces stop is much smaller than that near the position of the diversion cone. It can effectively reduce the situation in which the fish feces are dissolved back into the water body due to long-term flushing by strong water flow in traditional filtration methods, greatly reducing the filtration burden of the filter cotton and providing basic conditions for the filter cotton to cultivate nitrifying bacteria; at the same time, it is also convenient to take out the wire mesh for centralized cleaning, which is more convenient than the traditional filter cotton that needs to be kneaded and cleaned.

[0006] The present invention is further configured such that waistlines on both sides of the diversion cone cross section are both in the shape of concave arcs, and the lower ends of the waistlines are tangent to the virtual plane of the wire mesh.

[0007] In the above structure, the water flow is gently guided to adjust the flushing direction, thereby reducing the possibility of fish feces being broken up due to a sudden change in flow direction.

[0008] The present invention is further configured such that the drip outlet is located at the 6 o'clock position of the water distribution pipe section and a support is provided, and the support divides the drip outlet into the interval from 6 o'clock to 3 o'clock and the interval from 6 o'clock to 9 o'clock.

[0009] In the above structure, after the drip outlet is opened in the water distribution pipe, the supporting capacity of the lower side of its cross section is reduced, and the water distribution pipe is prone to sagging in the length direction. The provision of support members can effectively support the drip outlet, reduce or avoid sagging, and ensure the stability of water outlet from each drip outlet and the uniformity of flow rate.

[0010] The utility model is further configured such that a T-shaped three-way joint is provided at one end of the water inlet pipe located at the first box body, and the water inlet pipe is connected to the middle section of the water distribution pipe through the T-shaped three-way joint; plugs are provided at both ends of the water distribution pipe.

[0011] In the above structure, the T-shaped three-way joint can effectively balance the weight of both ends of the water distribution pipe.

[0012] The utility model is further configured as follows: a bracket is provided above the filter cotton, the bracket includes a U-shaped support ring, the wire mesh is installed on the support ring, and the bracket also includes a support leg connected to the support ring and abutting against the upper surface of the filter cotton.

[0013] In the above structure, the bracket is placed directly above the filter cotton, which is convenient for taking out and cleaning the fish feces.

[0014] The utility model is further configured such that a detachable filter screen is provided on the support legs between the wire screen and the filter cotton; and the mesh size of the wire screen is larger than that of the filter screen.

[0015] In the above structure, the filter screen can perform secondary filtration, further reducing the filtering burden of the filter cotton.

[0016] The utility model is further configured such that the mesh number of the wire mesh is 10-250 meshes, and the mesh number of the filter screen is 100-300 meshes.

[0017] In the above structure, the mesh ratio of the wire mesh to the filter mesh is preferably 2:1; the mesh number of the wire mesh is preferably 100, and the mesh number of the filter mesh is preferably 200.

[0018] The present invention is further configured such that overflow ports are provided at the bottoms of the first box body and the second box body.

[0019] In the above structure, if the filter cotton or the water filter holes of the first box body and the second box body are blocked, overflow can be caused to avoid overflow.

[0020] The present utility model is further configured such that the first box body is also provided with an indicator port connected to the filter cavity, the outer end of the indicator port is connected to an indicator tube extending downward and sealed at the end, the indicator tube is transparent, and an indicator buoy with a density less than that of water is provided in the indicator tube; the horizontal height of the indicator port is lower than the height of the overflow port of the first box body.

[0021] In the above structure, when the filter cotton or water filter hole of the first box body is blocked or the filtered water flow is reduced, the water flow can first enter the indicator tube before entering the overflow port to make the indicator buoy float up, so that the user can intuitively judge whether there is a filtering problem in the first box body.

[0022] The present invention is further configured such that a biochemical filter material is provided in the second box; and a bacteria house is provided in the third box.

[0024] The beneficial effects of the present invention are as follows: a drip outlet is provided in the range of 3 o'clock to 9 o'clock on the cross section of the water diversion pipe, which is divided into two by the diversion cone when the water flows downward, so that the water flow carries granular fish feces to flush to both sides of the diversion cone. In this process, the water flow changes from vertical movement to inclined and then to horizontal flow, carrying and flushing the fish feces to stop on the wire mesh away from the position of the diversion cone, and the water flow is gradually filtered by the wire mesh during the horizontal flow on the wire mesh. Therefore, the flushing force of the water flow at the position where the fish feces stop on the fish feces is much smaller than that near the position of the diversion cone, which can effectively reduce the situation in which the fish feces are dissolved back into the water body due to long-term flushing by the strong water flow in the traditional filtering method, greatly reduces the filtration burden of the filter cotton, and provides the basic conditions for the filter cotton to cultivate nitrifying bacteria; at the same time, it is also convenient to take out the wire mesh for centralized cleaning, which is more convenient than the traditional filter cotton that needs to be kneaded and cleaned.

DETAILED DESCRIPTION

[0030] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] refer to Figures 1 to 4 ,like Figures 1 to 4The water purification device shown in the figure includes a first box body 10, a second box body 20, and a third box body 30 stacked in sequence from top to bottom. The tops of the first box body 10, the second box body 20, and the third box body 30 are each provided with an opening 11 and a filter cavity 12 is formed in the opening 11. The bottoms of the first box body 10 and the second box body 20 are each provided with evenly distributed water filter holes 13. The first box body 10 is provided with a water inlet pipe 14, and the third box body 30 is provided with a water outlet pipe 31. The bottom of the filter cavity 12 of the first box body 10 is paved with filter cotton 15; A water distribution pipe 16 connected to the water inlet pipe 14 is also provided in the opening 11. The water distribution pipe 16 is horizontally arranged and has drip ports 161 spaced apart along its length. The drip ports 161 are located between 3 o'clock and 9 o'clock on the cross section of the water distribution pipe 16. A horizontally arranged wire mesh 40 is provided above the filter cotton 15. A diversion cone 50 is provided above the wire mesh 40 and is located below the water distribution pipe 16. The diversion cone 50 has an isosceles triangle cross section and is in the same direction as the water distribution pipe 16 in length. The top edge of the diversion cone 50 coincides with the projection of the axis of the water distribution pipe 16 on the surface of the wire mesh 40.

[0032] In the above structure, a drip outlet 161 is set in the range of 3 o'clock to 9 o'clock on the cross-section of the water diversion pipe 16, which is divided into two by the diversion cone 50 when the water flows downward, so that the water flow carries granular fish feces to flush to both sides of the diversion cone 50. In this process, the water flow changes from vertical movement to inclined and then to horizontal flow, carrying and flushing the fish feces to stop on the wire mesh 40 far away from the diversion cone 50. The water flow is gradually filtered by the wire mesh 40 in the process of horizontal flow on the wire mesh 40. Therefore, the flushing force of the water flow at the fish feces stopping position is much smaller than that near the diversion cone 50. It can effectively reduce the situation in which the fish feces are dissolved back into the water body due to long-term flushing by the strong water flow in the traditional filtering method, greatly reducing the filtration burden of the filter cotton 15 and providing basic conditions for the filter cotton 15 to cultivate nitrifying bacteria; at the same time, it is also convenient to take out the wire mesh 40 for centralized cleaning, which is more convenient than the traditional filter cotton 15 that needs to be kneaded and cleaned.

[0033] In this embodiment, the waistlines 51 on both sides of the cross-section of the diverter cone 50 are both concave arcs, and the lower ends of the waistlines 51 are tangent to the virtual plane of the screen 40 .

[0034] In the above structure, the water flow is gently guided to adjust the flushing direction, thereby reducing the possibility of fish feces being broken up due to a sudden change in flow direction.

[0035] In this embodiment, the drip outlet 161 is located at the 6 o'clock position of the cross section of the water distribution pipe 16 and is provided with a support member 162. The support member 162 divides the drip outlet 161 into the intervals from 6 o'clock to 3 o'clock and the interval from 6 o'clock to 9 o'clock.

[0036] In the above structure, after the drip outlet 161 is opened in the water distribution pipe 16, the supporting capacity of the lower side of its cross section is reduced, and the water distribution pipe 16 is prone to sagging in the length direction. The provision of the support member 162 can effectively support the drip outlet 161, reduce or avoid the sagging phenomenon, and ensure the stability of the water outlet from each drip outlet 161 and the uniformity of the flow rate.

[0037] In this embodiment, the water inlet pipe 14 is located at one end of the first box body 10 and is provided with a T-shaped three-way joint 141. The water inlet pipe 14 is connected to the middle section of the water distribution pipe 16 through the T-shaped three-way joint 141; the two ends of the water distribution pipe 16 are provided with plugs 163.

[0038] In the above structure, the T-shaped three-way connector 141 can effectively balance the weight of both ends of the water distribution pipe 16.

[0039] In this embodiment, a bracket 60 is provided above the filter cotton 15. The bracket 60 includes a U-shaped support ring 61. The wire mesh 40 is installed on the support ring 61. The bracket 60 also includes a support leg 62 connected to the support ring 61 and against the upper surface of the filter cotton 15.

[0040] In the above structure, the bracket 60 is placed directly above the filter cotton 15, which is convenient for taking out and cleaning the fish feces.

[0041] In this embodiment, a detachable filter screen 70 is further provided on the support leg 62 between the wire screen 40 and the filter cotton 15; the mesh size of the wire screen 40 is larger than that of the filter screen.

[0042] In the above structure, the filter screen can perform secondary filtration, further reducing the filtering burden of the filter cotton 15.

[0043] In this embodiment, the mesh size of the wire mesh 40 is 10-250 meshes, and the mesh size of the filter is 100-300 meshes.

[0044] In the above structure, the mesh ratio of the wire mesh 40 to the filter is preferably 2:1; the mesh number of the wire mesh 40 is preferably 100, and the mesh number of the filter is preferably 200.

[0045] In this embodiment, overflow ports 17 are provided at the bottoms of the first box body 10 and the second box body 20 .

[0046] In the above structure, when the filter cotton 15 or the water filter holes 13 of the first box body 10 and the second box body 20 are blocked, overflow can be performed to avoid overflow.

[0047] In this embodiment, the first box body 10 is further provided with an indicator port 18 connected to the filter chamber 12. The outer end of the indicator port 18 is connected to an indicator tube 181 extending downward and sealed at the end. The indicator tube 181 is transparent and has an indicator buoy 182 with a density less than that of water. The horizontal height of the indicator port 18 is lower than the height of the overflow port 17 of the first box body 10.

[0048] In the above structure, when the filter cotton 15 or the water filter hole 13 of the first box body 10 is blocked or the filtered water flow is reduced, the water flow can preferentially enter the indicator tube 181 before entering the overflow port 17 to make the indicator buoy 182 float up, so that the user can intuitively judge whether there is a filtering problem in the first box body 10.

[0049] In this embodiment, a biochemical filter material (not shown in the figure) is provided in the second box 20 ; and a bacteria house (not shown in the figure) is provided in the third box 30 .

[0050] In the above structure, the biochemical filter material (not shown in the figure) is one or more of ceramic rings, green zeolite, nanospheres, coral bones, white breathing rings, red breathing rings, medical stone, and volcanic rocks; the filter cotton 15 is one or more of cashmere cotton, hand-torn cotton, 9D cotton, 8D cotton, and magic carpet bags.

[0051] The beneficial effects of the present invention are as follows: a drip outlet 161 is provided in the range of 3 o'clock to 9 o'clock on the cross section of the water diversion pipe 16, which is divided into two by the diversion cone 50 when the water flows downward, so that the water flow carries granular fish feces to flush to both sides of the diversion cone 50. In this process, the water flow changes from vertical movement to inclined and then to horizontal flow, carrying and flushing the fish feces to stop on the wire mesh 40 away from the position of the diversion cone 50, and the water flow is gradually filtered by the wire mesh 40 in the process of horizontal flow on the wire mesh 40. Therefore, the flushing force of the water flow at the position where the fish feces stop for the fish feces is much smaller than that near the position of the diversion cone 50, which can effectively reduce the situation in which the fish feces in the traditional filtering method are dissolved back into the water body due to long-term flushing by the strong water flow, greatly reduces the filtration burden of the filter cotton 15, and provides the basic conditions for the filter cotton 15 to cultivate nitrifying bacteria; at the same time, it is also convenient to take out the wire mesh 40 for centralized cleaning, which is more convenient than the traditional filter cotton 15 that needs to be kneaded and cleaned.
