Detailed Description
The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention.
The embodiment of the invention comprises the following steps: a modularized tail water solid-liquid separation device for fishery is disclosed as shown in attached figures 1-3, and comprises 1 relatively sealed box body 1, a water inlet 2 is arranged above a back plate of the box body 1, 1 flow stabilizing box 3 connected with the back plate and inner walls of a left side plate and a right side plate is arranged in the box body 1 below the water inlet 2, 1 overflow table 4 is arranged in front of the top of the flow stabilizing box 3, a gap is formed between the top of the overflow table 4 and the top of the box body 1, 1 partition plate 5 is arranged in front of the bottom in the box body 1, two ends of the partition plate 5 are respectively connected with the left side of the box body 1, the inboard wall connection of right both sides board, baffle 5 separate box 1 for left and right two regions, and the left side is regional to be clean water tank 6, and the right side is regional for the dirty groove 7 of collection, and the dirty 7 tops in groove of collection are equipped with 1 drain, is equipped with delivery port 8 on the regional box 1 in clean water tank 6 place, is connected with the sieve bars 9 that the slant set up between 5 tops of baffle and the 4 tip of overflow platform.
In the use, breed tail water and enter into box 1 through water inlet 2, drop to in the stationary flow case 3, make torrential water velocity become slow, the rivers of filler stationary flow case 3 spill over from overflow platform 4, trickle to on the sieve bars 9 under the action of gravity, because water velocity is slower, rivers are relatively small to the impact force of sieve bars 9, rivers are difficult to kick-back, thereby make the rivers homoenergetic that flow to on the sieve bars 9 realize the separation of solid box liquid through sieve bars 9, liquid after the filtration drops to in the clear water tank 6 of sieve bars 9 below, finally discharge from delivery port 8. And the solid matter falls into the sewage collecting groove 7 at the tail part along the extension screen grid 9, and when a certain amount of the solid matter is collected, the solid matter is manually discharged from a sewage discharge outlet. After solid and liquid are separated, part of the solid is attached to the surface of the sieve grid 9, then the water to be treated flows downwards tightly to the sieve grid 9, and the solid gathered on the sieve grid 9 is continuously washed by the liquid and gathered in the sewage collection tank 7, so that the function of self-cleaning the sieve grid 9 is achieved.
The mesh gap of the sieve grid 9 is 0.2-0.25 mm. The gap can ensure that the sieve grid 9 can well separate solid and liquid.
The included angle between the sieve grid 9 and the horizontal plane is 30-60 degrees. The angle is less than 30 degrees, and water velocity is slower, and the solid is attached to sieve bars 9 easily, and the impact force of rivers is less, can't realize the self-cleaning to sieve bars 9 through rivers, and the device volume is great relatively moreover. When the angle is more than 60 degrees, the water flow speed is high, and the separation effect of solid and liquid is poor.
A baffle plate 10 positioned in front of the water inlet 2 is arranged in the box body 1. Baffle 10 is "7" font structure, and afterbody and 1 backplate inner wall connection of box, and the front end is kept off in water inlet 2 the place ahead, sets up baffle 10 and can avoid directly dashing out from overflow platform 4 from the rivers that water inlet 2 got into, can't realize the slow flow.
The overflow table 4 department is equipped with the breach, and this breach is overflow mouth 13, and overflow mouth 13 is connected with sieve bars 9, and when sieve bars 9 width was less than 1 inside width of box, be greater than overflow mouth 13's width, the sieve bars 9 left and right sides respectively is equipped with 1 dog 12, and dirty 7 both ends in groove that gathers are equipped with 1 grid 11 respectively, and grid 11 is located the 12 outsides of adjacent dog, is equipped with the hole of permeating water on baffle 5 between dog 12 and the 1 curb plate of adjacent box, and 1 bottom plate of box sets up for the slant.
In the use process, the water flow after the steady flow box 3 slowly flows down to the sieve grid 9 from the overflow port 13, and the stop blocks 12 arranged on the left side and the right side of the sieve grid 9 can prevent the water flow from falling into the clean water box 6 below the sieve grid 9 from the gap between the side plates of the box body 1, so that the separation cannot be realized. In the solid-liquid separation process, a small part of liquid can also fall into the sewage collecting tank 7 along with solid matters, the grid 11 is arranged to block the solid matters, and meanwhile, the liquid can flow into the sewage collecting tank 7 between the grid 11 and the box body 1 after passing through the grid 11, and finally, the liquid can flow into the clean water tank 6 through the water permeable holes because the partition plate 5 of the sewage collecting tank 7 at the position is provided with the water permeable holes. The bottom plate of the box body 1 is obliquely arranged, wherein the bottom plate of the area where the sewage collecting groove 7 is positioned at the highest position, so that the liquid in the clean water tank 6 can be prevented from flowing back to the sewage collecting groove 7 through the water permeable holes on the partition plate 5.
As shown in fig. 4-5, the dirt collecting groove 7 can be made as following structure, the dirt collecting groove 7 is 1 single U-shaped groove structure, and the bottom, the side surface and other parts are not connected with the box body 1. The two ends of the sewage collecting groove 7 are grids 11, and the grids 11 are not connected with the inner wall of the side plate of the box body 1. The back in dirty groove 7 of collection is baffle 5 and sieve bars 9 fixed connection promptly, sieve bars 9 tip and overflow mouth 13 pass through hinge activity rotation and are connected, the preceding curb plate in dirty groove 7 of collection and regulation pole 14 fixed connection, it stretches out to the box 1 outside to adjust the hole 16 that wears on the case lid 15 of box 1 to adjust the pole 14 other end, should wear the hole 16 aperture and be far greater than the diameter of adjusting pole 14, adjust the pole 14 and go up the interval and set up a plurality of regulation holes 17, sieve bars 9 rotates 5 around its head end of being connected with overflow mouth 13 promptly, just set up 1 regulation hole 17 on adjusting pole 14. And further comprises a pin 18 insertable into the adjustment hole 17. By pulling or pushing the adjusting rod 14, the sieve grid 9 can be driven to rotate around the head end connected with the overflow port 13 under the action of pulling force or pushing force. The rotating angle can be confirmed by observing the position of the adjusting hole 17 on the adjusting rod 14, when the adjusting rod rotates to a required angle, the pin 18 is inserted into the corresponding adjusting hole 17, and the pin 18 is clamped on the box cover 15, so that the adjusting rod 14 is fixed, and the sewage collecting tank 7 and the sieve grid 9 can be fixed. The angle of the screen 9 is adjusted by the adjusting rod 14, so that the filtering requirements of different environments are met. The small part of the liquid flowing from the sieve grids 9 into the sewage collecting tank 7 directly drops into the box body 1 from the grids 11 at the two sides of the sewage collecting tank 7.
The bottom plate of the box body 1 is provided with an L-shaped limiting block 19, and the L-shaped limiting block 19 is positioned at the rear side of the sewage collecting groove 7. When the angle between the sieve grid 9 and the horizontal plane is 60 degrees, the L-shaped limiting block 19 just supports the bottom of the sewage collecting groove 7, the back of the sewage collecting groove 7 is in contact with the L-shaped limiting block 19, and the sewage collecting groove 7 and the sieve grid 9 can be supported through the L-shaped limiting block 19 at the moment.
