Description

Technical Field

[0001] The utility model relates to the technical field of purification sedimentation tanks, in particular to a circulating purification sewage sedimentation tank. Background Art

[0002] Hanging water fish refers to certain fish that are raised in clear water ponds after reaching adulthood. During this period, they are not fed feed, grass, or other bait, and no medication is used. This allows the fish to "slim down," reduce muscle fat content, make the meat firmer, and reduce the fishy odor. Traditional hanging water fish farming, which relies on cages in reservoirs, lakes, and rivers, is being phased out, with a shift toward land-based, integrated farming. Pond farming, however, is difficult to achieve on a large scale due to issues such as water changes, drainage, and sewage disposal, as well as geographical constraints. Therefore, the shift toward land-based and factory-style farming has become a major trend in the aquaculture industry.

[0003] At present, the source water for land-based aquaculture of hanging fish mainly includes purified tail water and external source water. The external source water is extracted from the outside, such as rivers, lakes, reservoirs, etc. After the existing land-based aquaculture extracts the source water, it is necessary to let the extracted source water settle to remove floating impurities in the source water. At the same time, the tail water after purification often still retains some floating impurities. The existing filtration method generally uses a pump body to push the water flow through the grid net. The grid of the grid net intercepts the impurities contained in the water body. The filtered water flows into the sedimentation tank behind for sedimentation, which requires more space and high civil engineering costs. The pump body needs to be maintained daily. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a sewage sedimentation tank which is easy to maintain daily and can filter impurities in the upper and lower layers of the water body through the self-flow of the water body to circulate and purify.

[0005] The technical solution adopted by the present invention is: the present invention includes a pool body, at least two groups of spacer components forming flow channels in the pool body, and a number of filter components are arranged between two adjacent groups of the spacer components, the first side of the pool body is provided with an inlet pipe for supplying source water and pretreated tail water, the second side of the pool body is provided with an outlet pipe for discharging sedimentation filtered water, each of the filter components includes a first filter group for filtering upper impurities, and a second filter group for filtering bottom impurities, the first filter group and the second filter group are both detachably connected to a filter group, and a flow space for middle-layer flow water to pass through is formed between the first filter group and the second filter group.

[0006] Furthermore, the first filter group includes a first filter frame fixedly connected to the pool body, and a first water retaining member arranged on the outside of the first filter frame and pressed tightly against the spacer assembly. The first filter frame is formed with a first slide groove, and the first slide groove is provided with a plurality of first clips for the filter group to engage and limit.

[0007] Furthermore, the second filter group includes a second filter frame fixedly connected to the pool body, and a second water retaining member arranged on the outside of the second filter frame and pressed tightly against the spacer assembly. The second filter frame is formed with a second slide groove, and the second slide groove is provided with a number of second clips for the filter group to engage and limit.

[0008] Furthermore, the filter group includes a filter frame and several filter screens that slide with the filter frame. Both sides of the filter frame are provided with clearance grooves, and each of the clearance grooves is rotatably connected to a support limit group that engages and limits with the first filter group and the second filter group.

[0009] Furthermore, the give way groove is formed with a sliding cavity and a rotating hole, and a plurality of mounting holes are provided in the sliding cavity, each of the mounting holes is provided with an elastic member, and a rotating pin is provided in the rotating hole. The support and limiting group includes a rotating card rotatably connected to the rotating pin, a push block provided below the rotating card and slidingly cooperating with the sliding cavity, and a push column provided above the rotating card and slidingly cooperating with the filter frame. The bottom of the push block is tightly fitted with the plurality of elastic members, the upper end of the push column passes through the upper surface of the filter frame, and the lower end of the push column pushes the rotating card to rotate.

[0010] Furthermore, the spacer assembly includes an isolation plate for isolating water flow, and a plurality of fixing columns that are mounted on the isolation plate and fixedly connected to the pool body. One end of the isolation plate is sealed to the side wall of the pool body, and the other end of the isolation plate is open to the pool body.

[0011] Furthermore, the water inlet pipe is formed with a water inlet that is inclined upward.

[0012] The beneficial effects of the present invention are as follows: since the water inlet pipe of the present invention is used to flow in external water sources and pretreated tail water, the upwardly inclined water inlet allows the inflowing water to flow upward, effectively preventing the water from entering and stirring up the precipitated dirt at the bottom of the pool. After the sewage enters the pool body, the larger dirt settles to the bottom layer, and the lighter dirt floats on the upper layer and moves with the water flow. The first filter group and the second filter group intercept the dirt at the upper and lower ends of the pool body. The flow space formed between the first filter group and the second filter group is for the middle layer of clean water to pass through, which has the effect of intercepting dirt without affecting the water flow efficiency. The water flow does not require an additional pump or motor to drive it, effectively saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] like Figures 1 to 7As shown, in this embodiment, the utility model includes a pool body 1, and also includes at least two groups of spacer components 4 forming a flow channel in the pool body 1, and a plurality of filter components 5 are arranged between two adjacent groups of the spacer components 4.

Each of the filter components 5 includes a first filter group 51 for filtering upper impurities and a second filter group 52 for filtering bottom impurities. The first filter group 51 and the second filter group 52 are both detachably connected to a filter group 53. The first filter group 51 and the second filter group 5 2 forms a flow space for the middle layer of flowing water to pass through. The water inlet pipe 2 is used to flow in external water source and pretreated tail water. The upward inclined water inlet 21 allows the incoming water to flow upward, effectively preventing the water from entering and stirring up the sediment at the bottom of the pool. After the sewage enters the pool body 1, the larger dirt settles to the bottom, and the lighter dirt floats on the upper layer and moves with the water flow. The first filter group 51 and the second filter group 52 intercept the dirt at the upper and lower ends of the pool body 1. The flow space formed between the first filter group 51 and the second filter group 52 is for the middle layer of clean water to pass through, which has the effect of intercepting dirt without affecting the water flow efficiency. The water flow does not require an additional pump or motor to drive, which effectively saves costs.

[0022] In this embodiment, the first filter group 51 includes a first filter frame 511 fixedly connected to the pool body 1, and a first water stop 512 arranged on the outside of the first filter frame 511 and pressed against the spacer assembly 4, the first filter frame 511 is formed with a first slide groove 513, and the first slide groove 513 is provided with a number of first clips 514 for the filter group 53 to be engaged and limited. The first water stop 512 is a rubber structure, which is squeezed with the spacer assembly 4 to form a seal, blocking the water flow from flowing through the side of the first filter group 51, thereby improving the filtration effectiveness. The first filter frame 511 is provided with two groups, and the distance between the two groups of first filter frames 511 is greater than the length of the filter frame 54. A number of first clips 514 are equidistantly arranged in the first slide groove 513, and the upper surface of each first clip 514 is formed with an arc surface, which is supported and limited by the rotating card 571, and the first slide groove 513 is guided and matched with the filter frame 54.

[0023] The second filter group 52 is provided with a plurality of second filter frames 521 and a plurality of second filter frames 522, each of which is fixed to the second filter frame 521 and is pressed against the second filter frame 521. The second filter frame 521 is provided with a second slide groove 523, and the second slide groove 523 is provided with a plurality of second clips 524 for the filter group 53 to engage and limit. The second water stop 522 is a rubber structure, which is squeezed with the spacer assembly 4 to form a seal, blocking the water flow from the side of the second filter group 52 and improving the filtering effectiveness. The second filter frame 521 is provided with two groups, and the distance between the two groups of second filter frames 521 is greater than the length of the filter frame 54. The plurality of second clips 524 are arranged at equal intervals in the second slide groove 523, and the upper surface of each second clip 524 is formed with an arc surface, which is supported and limited by the rotating card 571, and the second slide groove 523 is guided and matched with the filter frame 54.

[0024] The filter screen 55 is a plurality of filter screens 55 that are slidably matched with the filter screen frame 54. Both sides of the filter screen frame 54 are provided with a clearance groove 56. Each of the clearance grooves 56 is rotatably connected to a support limit group 57 that is engaged and limited with the first filter group 51 and the second filter group 52. A plurality of groups of slots are formed on the upper part of the filter frame 54. The size of the slots is equal to the width of the filter screen 55, which are used to put in and take out the filter screen 55. The clearance grooves 56 are arranged so that the rotating card 571 has a rotation space. The mesh number of the filter screen 55 can be increased or decreased according to the impurities in the water entering the pool body 1 to improve the purification and filtration efficiency. Filter cotton can be placed between every two groups of filter screens 55 to improve the filtration efficiency. The filter screen group 53 structure is detachable. The user can adjust the height of the filter frame 54 according to the liquid level of the pool body 1 to ensure that the filter screen group 53 can effectively filter the upper and bottom impurities in the pool body 1.

[0025] In this embodiment, the give way groove 56 is formed with a sliding cavity 561 and a rotating hole 562, a plurality of mounting holes 563 are provided in the sliding cavity 561, each of the mounting holes 563 is provided with an elastic member 574, a rotating pin 564 is provided in the rotating hole 562, and the support limit group 57 includes a rotating card 571 rotatably connected to the rotating pin 564, a push block 572 provided below the rotating card 571 and slidingly cooperating with the sliding cavity 561, and a push block 572 provided above the rotating card 571 and cooperating with the sliding cavity 561. The filter frame 54 is slidably fitted with a push post 573, the bottom of the push block 572 is tightly fitted with several of the elastic members 574, the upper end of the push post 573 passes through the upper surface of the filter frame 54, and the lower end of the push post 573 pushes the rotating card 571 to rotate, the elastic member 574 is a spring, and the elastic member 574 is a copper-nickel alloy with good corrosion resistance. The push block 572 is made of rubber and has good corrosion resistance in water. The rotating hole 562 is located at the upper part of the give way groove 56, and the sliding cavity 561 is located at the give way groove. At the lower part of the groove 56, the opening of the sliding cavity 561 is smaller than the size of the sliding cavity 561, preventing the pushing block 572 from falling out when moving in the pushing direction of the elastic member 574. The rotating card 571 rotates freely in the yielding groove 56 through the rotating pin 564. The pushing block 572 located below the rotating card 571 is pushed upward under the action of multiple elastic members 574, so that the rotating card 571 is pushed outward. The width of the movable end of the two groups of rotating cards 571 pushed out is greater than the width of the filter frame 54, so that the filter frame 54 is under the action of the two groups of rotating cards 571. The bottom is limited by the first filter group 51 or the second filter group 52. The structure is simple and easy to use. When the position needs to be adjusted or disassembled, press the two push rods that pass through the upper surface of the filter frame. The push rods move downward to apply a downward force to the rotating card 571, causing the rotating card 571 to flip downward. The push piece moves downward along the direction of the sliding cavity 561, and multiple elastic parts 574 are compressed until the width between the rotating cards 571 on both sides is less than or equal to the width of both sides of the filter frame 54. The filter frame 54 can be taken out or the upper and lower positions of the filter frame 54 can be adjusted.

[0026] In this embodiment, the spacer assembly 4 includes an isolation plate 41 for isolating water flow, and a number of fixing columns 42 that are sleeved on the isolation plate 41 and fixedly connected to the pool body 1. One end of the isolation plate 41 is sealed with the side wall of the pool body 1, and the other end of the isolation plate 41 is in an open state with the pool body 1. The isolation plate 41 is a plastic plate or plastic cloth with good hydrophobic effect. It can effectively form a runway structure to guide the flow direction of water. The fixing column 42 is sleeved on the isolation plate 41, and the lower end of the fixing column 42 is fixedly connected to the pool body, so that the isolation plate is stably installed in the pool body.

[0027] In this embodiment, the water inlet pipe 2 is formed with a water inlet 21 that is inclined upward.

[0028] The working principle of this utility model:

[0029] A runway-shaped water flow space is formed by setting the installation positions of multiple groups of spacer components 4 in the pool body 1. Multiple filter components 5 are installed in two adjacent groups of spacer components 4 to intercept impurities in the upper layer and the bottom layer of the water body;

[0030] When the filter group 53 is installed, the rotating card 571 rotates freely in the clearance groove 56 via the rotating pin 564. The pushing block 572 located below the rotating card 571 is pushed upward by the multiple elastic members 574, so that the rotating card 571 is pushed outward. The width of the movable ends of the two groups of rotating cards 571 is greater than the width of the filter frame 54. Under the action of the two groups of rotating cards 571, the filter frame 54 is limitedly engaged with the first filter group 51 or the second filter group 52.

[0031] When the position needs to be adjusted or disassembled, the two push rods passing through the upper surface of the filter frame are pressed. The push rods move downward to apply a downward force to the rotating card 571, causing the rotating card 571 to flip downward. The push piece moves downward along the sliding cavity 561, and the multiple elastic members 574 are compressed until the width between the rotating cards 571 on both sides is less than or equal to the width of the two sides of the filter frame 54. The filter frame 54 can then be removed or the upper and lower positions of the filter frame 54 can be adjusted.

[0032] The water flows in along the water inlet pipe 2 and flows out at the water inlet 21 inclined upward in the water inlet pipe 2. The inflowing water maintains an upward movement trend, effectively preventing the water flow from stirring up the sediment at the bottom of the pool. After the sewage enters the pool body 1, the larger dirt settles to the bottom, and the lighter dirt floats on the upper layer and moves with the water flow. The first filter group 51 and the second filter group 52 intercept the dirt at the upper and lower ends of the pool body 1. The flow space formed between the first filter group 51 and the second filter group 52 is for the middle layer of clean water to pass through, which has the effect of intercepting dirt without affecting the water flow efficiency. During the flow process, the impurities in the middle layer gradually sink to the bottom under the action of gravity and are intercepted and filtered by the next filter group 53 set at the bottom.

[0033] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
