Even though rivers, lakes and seas can eliminate foreign pollutants through various physical, chemical and biological methods, it is difficult to eliminate large-scale pollution in a short period of time. Therefore, water pollution control is necessary.

[0003] Usually, adding corresponding chemicals according to the type of water pollution is one of the fastest and most effective water pollution control measures. When carrying out drug feeding operations in flowing waters, considering the fluidity of the water body and the density of the surface sewage, most of the drug feeding methods usually use deep pipes for drug injection, which has poor effect on the treatment of surface sewage and suspended solids, and its drug feeding effect and treatment are limited.

DETAILED DESCRIPTION

[0020] See also Figure 1-3 , the embodiments of the utility model are further described;

[0021] A water pollution treatment dosing device comprises a dosing box 1 and a floating frame 2, wherein the floating frame 2 is arranged opposite to one side of the dosing box 1, a mixing chamber 8 is arranged in the dosing box 1, a dosing chamber port 9 is arranged through the mixing chamber 8, and a pump group 12 is arranged at one end of the mixing chamber 8 opposite to the dosing chamber port 9, a vortex cylinder 4 is arranged through the end of the dosing box 1 opposite to the mixing chamber 8, a vortex wheel group 11 is arranged in the vortex cylinder 4, and a valve port pipe seat 10 is arranged between the vortex cylinder 4 and the mixing chamber 8;

[0022] A handle seat 3 is fixed between the floating frame 2 and the medicine feeding box 1, a through pipe 13 is buried between the floating frame 2 and the handle seat 3, and the valve port pipe seat 10 is connected to the through pipe 13;

[0023] A feeding frame 5 is provided under the floating frame 2, and a floating plate 6 is provided under the feeding frame 5. A valve port shaft 7 is provided through the floating plate 6, the feeding frame 5 and the floating frame 2, and a compression pipe 14 is provided between the valve port shaft 7 and the through pipe 13.

[0024] The water pollution treatment and dosing device adopts a compression mixing method. The vortex wheel group 11 in the vortex cylinder 4 works to suck the water into the mixing chamber 8 to mix with the drug substance. When the pump group 12 works, the mixed water is compressed and transported along the valve port pipe seat 10 to the through pipe 13, and through the compression pipe 14 in the open and closed state, the diffraction compression pipe 14 outputs to the floating plate 6, and as the water surface contacts the floating plate 6, the mixed water is taken away from it, so as to achieve the purpose of drug delivery;

[0025] Considering that the targeted drug delivery to the water surface and shallow water bodies will result in poor mixing effect between the drug and the water body after being delivered to the water surface due to the influence of the fluidity of the shallow water surface and the density of pollutants, the subsequent drug delivery operation is carried out by first extracting the water body to the mixing chamber 8 through the vortex cylinder 4 for compression and mixing with the drug, so as to ensure the delivery effect of the drug;

[0026] Compared with the traditional deep-drying drug delivery device, the device is arranged on the water surface through the floating structure of the floating frame 2, the drug delivery frame 5 and the floating plate 6, and then the compression tube 14 is opened by the change of the liquid level height when the floating plate 6 floats up, and then the drug delivery is completed by the compressed output of the drug liquid and the contact between the surface of the floating plate 6 and the water surface, avoiding the problem of poor water surface treatment effect of the traditional drug delivery device.

[0027] Furthermore, the floating frame 2 and the feeding rack 5 are cross-staggered plate structures, so that the staggered floating frame 2 and the feeding rack 5 can be stable on the water surface while ensuring the effective coverage area of ​​the feeding rack 5.

[0028] Furthermore, the valve mouth pipe seat 10 is a multi-channel diverter pipe structure, and the valve mouth pipe seat 10 has a one-way channel between the vortex tube 4 and the mixing chamber 8. The one-way channel pipe structure prevents the water from flowing back along the vortex tube 4 and affecting the compressed water pressure of the compressed mixed water when the subsequent pump group 12 works, thereby ensuring the stability of the supply flow of the mixed water.

[0029] Furthermore, the cross-section of the feeding rack 5 and the floating plate 6 is a concave-convex docking structure, and both the feeding rack 5 and the floating plate 6 are lightweight frame structures. The matching feeding rack 5 and floating plate 6 structures can ensure that the floating plate 6 is maintained in the feeding rack 5 structure when the liquid level fluctuates, so as to stabilize the floating structure of the floating plate 6 to ensure the stability of the opening and closing of the axial compression passage of the compression tube 14.

[0030] Furthermore, the compression tube 14 and the valve port shaft 7 are axial pneumatic compression structures, and the opening and closing of the tube mouth of the compression tube 14 corresponds to the height position of the floating plate 6. Specifically, the bottom of the compression tube 14 is axially broken through by the change in liquid level when the floating plate 6 floats up to open the passage between the compression tube 14 and the floating plate 6, that is, under the influence of the compressed and transported high-pressure mixed water, the mixed water is transported to the surface of the floating plate 6 by hydraulic pressure.

[0031] Furthermore, a liquid level valve tube 15 is inserted between the float plate 6 and the compression tube 14, and a compression spring coil is filled between the liquid level valve tube 15 and the inner wall of the feeding rack 5. The setting of the liquid level valve tube 15 and the compression spring coil is used to further limit the floating height of the float plate 6 corresponding to the opening and closing state of the compression tube 14, that is, the floating height limit position of the liquid level valve tube 15 is changed by adjusting the number of turns of the compression spring coil to set the opening and closing state of the compression tube 14, that is, it is convenient to adjust the dosing position of the float plate 6 structure.
