Detailed implementation manners

[0023] The technical solution of the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] As Figure 1-6As shown in the figure, the sewage intercepting device for decomposing nitrogen and phosphorus provided in this embodiment includes a U-shaped base 1. A replaceable nitrogen and phosphorus adsorption structure 2 is clamped and installed at the U-shaped opening of the U-shaped base 1. The replaceable nitrogen and phosphorus adsorption structure 2 includes a clamping and fixing frame 3, a first filter screen 4 installed on one side of the clamping and fixing frame 3, a second filter screen 5 installed on the other side of the clamping and fixing frame 3, a third filter screen 6 clamped and installed in the clamping and fixing frame 3, a first adsorption plate 7 installed between the first filter screen 4 and the third filter screen 6, and a second adsorption plate 8 installed between the second filter screen 5 and the third filter screen 6. A hoisting machine 9 is arranged on the upper end surface of the U-shaped base 1, and a water blocking structure 10 is arranged on the side surface of the U-shaped base 1. The U-shaped base 1 is used for clamping and fixing the replaceable nitrogen and phosphorus adsorption structure 2; the replaceable nitrogen and phosphorus adsorption structure 2 is used for sequentially replacing and installing when replacing the adsorption-saturated adsorption plates, so that it is not necessary to block the water flow in advance when replacing the adsorption-saturated adsorption plates; the clamping and fixing frame 3 is used for fixing and supporting the first filter screen 4 and the second filter screen 5, and at the same time facilitating the clamping and fixing of the third filter screen 6. The first filter screen 4 and the second filter screen 5 play a role in isolating larger garbage and at the same time play a role in fixing the first adsorption plate 7 and the second adsorption plate 8. The third filter screen 6 is used for separating the first adsorption plate 7 and the second adsorption plate 8, so as to realize the sequential replacement and installation of the adsorption-saturated adsorption plates without blocking the water flow in advance and under the state of water flow circulation; the first adsorption plate 7 and the second adsorption plate 8 are used for adsorbing nitrogen and phosphorus elements in the sewage, so as to reduce the nitrogen and phosphorus content in the water body; the hoisting machine 9 is used for hoisting the replaceable nitrogen and phosphorus adsorption structure 2, and at the same time cleaning or replacing the clamping and fixing frame 3, the first filter screen 4, the second filter screen 5 and the third filter screen 6 in the replaceable nitrogen and phosphorus adsorption structure 2. The hoisting machine 9 can also hoist and replace the adsorption-saturated first adsorption plate 7 and second adsorption plate 8; the water blocking structure 10 makes the water flow rate of the water adsorbed and filtered at the outlet slower and the impact force smaller, so that the flowing sewage can contact and absorb with the first adsorption plate 7 and the second adsorption plate 8 for a longer time, and the nitrogen and phosphorus adsorption effect is better.

[0025] Further, as Figure 1 , Figure 2 and Figure 4 shown, a first clamping groove 11 adapted to the clamping and fixing frame 3 is opened on the inner wall of the U-shaped opening of the U-shaped base 1. Two ends of the upper surface of the clamping and fixing frame 3 are symmetrically provided with first hanging rings 12. The first clamping groove 11 is used for clamping and fixing the clamping and fixing frame 3, and the first hanging rings 12 are used for hoisting the clamping and fixing frame 3.

[0026] Further, as Figure 1 and Figure 2 shown, two ends of the upper surface of the first adsorption plate 7 are symmetrically provided with second hanging rings 13, and two ends of the upper surface of the second adsorption plate 8 are symmetrically provided with third hanging rings 14. The second hanging rings 13 are used for hoisting the first adsorption plate 7, and the third hanging rings 14 are used for hoisting the second adsorption plate 8.

[0027] Further, as Figure 1 shown in Figure 2 , both sides and the lower surface of the third filter screen 6 are provided with clamping protrusions 15, and clamping grooves 16 adapted to the clamping protrusions 15 are formed on the inner wall of the clamping fixed frame 3. The clamping protrusions 15 and the clamping grooves 16 are used to clamp and install the third filter screen 6 in the clamping fixed frame 3.

[0028] Further, as Figure 1 shown in Figure 2 , the first filter screen 4 is fixedly installed on one side of the clamping fixed frame 3 by bolts, and the second filter screen 5 is fixedly installed on the other side of the clamping fixed frame 3 by bolts, which is convenient for replacing or removing and cleaning the first filter screen 4 or the second filter screen 5.

[0029] Further, as Figure 4 , Figure 5 and Figure 6 shown in , the hoisting machine 9 includes two supports 17, a support plate 18 arranged on the upper end surfaces of the two supports 17, and a winch 19 symmetrically arranged on the upper surface of the support plate 18. The two supports 17 are used to fixedly connect the hoisting machine 9 to the upper surface of the U-shaped base 1. The support plate 18 is used to connect the two supports 17 and at the same time fixedly support the winch 19. The winch 19 plays a role in hoisting.

[0030] Further, as Figure 4 , Figure 5 and Figure 6 shown in , the winch 19 includes a winding motor 20, a winding concave wheel 21 arranged at the output end of the winding motor 20, a steel cable 22 arranged on the winding concave wheel 21, and a hook 23 arranged at the end of the steel cable 22. The winding motor 20 is used to provide the driving force for the winch 19 to wind. The steel cable 22 and the hook 23 are used to hook a specified object and complete the hoisting of the specified object under the drive of the winding motor 20.

[0031] Further, as Figure 3 shown in Figure 6 , the water blocking structure 10 includes a U-shaped support frame 24 and a speed reducing plate 25 longitudinally and sequentially hinged at the U-shaped opening of the U-shaped support frame 24. The U-shaped support frame 24 is used to support and fix the speed reducing plate 25. The speed reducing plate 25 is used to reduce the flow rate and impact force of water.

[0032] As Figure 1-Figure 6As shown, the principle of the pollution intercepting device for eliminating nitrogen and phosphorus provided in this embodiment is as follows: when using the device, the U-shaped base 1 and the water blocking structure 10 should be buried at the water outlet first, and then the third filter screen 6 should be inserted and fixed in the card-embedded fixing frame 3, and then the first filter screen 4 and the second filter screen 5 are respectively fixed on both sides of the card-embedded fixing frame 3 by bolts, and the first adsorption plate 7 is installed in the cavity between the first filter screen 4 and the third filter screen 6, and the second adsorption plate 8 is installed in the cavity between the second filter screen 5 and the third filter screen 6, and then the hook 23 at the end of the steel cable 22 is hooked on the first lifting ring 12, and under the action of the winding motor 20, the card-replaceable nitrogen and phosphorus adsorption structure 2 is safely inserted and hoisted into the U-shaped opening of the U-shaped base 1;

[0033] After the installation of the device is completed, the operation can be started. When the sewage flows into the device, the sewage will first flow into the water-blocking structure 10. At this time, the deceleration plate 25 in the water-blocking structure 10 will dissolve the impact of the sewage, making the turbulent sewage flow rate slower, so that the sewage can contact the first adsorption plate 7 and the second adsorption plate 8 for a longer time, so that the first adsorption plate 7 and the second adsorption plate 8 can better adsorb the excess nitrogen and phosphorus elements in the sewage, and also protect the nitrogen and phosphorus adsorption structure 2 that can be replaced separately, so that it does not need to directly face the impact of the torrent;

[0034] When the first adsorption plate 7 and the second adsorption plate 8 are saturated with adsorption after a long operation, the winding motor 20 in the winding machine 19 must first rotate clockwise to lower the steel cable 22, and then hook the hook 23 at the end of the steel cable 22 on the second hanging ring 13. At this time, the winding motor 20 rotates counterclockwise, and then tightens the steel cable 22 to remove the saturated first adsorption plate 7. After that, a new first adsorption plate 7 can be taken out and hooked on the hook 23. Then the winding motor 20 rotates clockwise to lower the steel cable 22, and install the new first adsorption plate 7 back to its original position;

[0035] After replacing the first adsorption plate 7, the hook 23 can be removed from the second lifting ring 13, and then the hook 23 can be hooked on the third lifting ring 14. The winding motor 20 rotates counterclockwise, tightens the steel cable 22 to take out the saturated second adsorption plate 8, and hooks the new second adsorption plate 8 on the hook 23. Then the winding motor 20 rotates clockwise to lower the steel cable 22, and install the new second adsorption plate 8 back to its original position. When replacing the adsorption plate, the first adsorption plate 7 should be replaced first, because the saturation state of the first adsorption plate 7 will be more serious than that of the second adsorption plate 8. This makes it possible for the second adsorption plate 8 to temporarily adsorb the sewage flowing through when the first adsorption plate 7 is lifted, so there is no need to block the water flow in advance.

[0036] The above description shows and describes the preferred embodiments of the present utility model. It should be understood that the present utility model is not limited to the forms disclosed herein, and any modifications and changes made by those skilled in the art without departing from the spirit and scope of the present utility model shall fall within the protection scope of the appended claims of the present utility model.
