Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a dosing device for water treatment. Background Art

[0002] Water treatment includes sewage treatment and drinking water treatment. In some places, sewage treatment is further divided into two types, namely sewage treatment and reclaimed water reuse. The water treatment agents commonly used in water treatment are: polyaluminum chloride, polyaluminum ferric chloride, basic aluminum chloride, polyacrylamide, activated carbon and various filter materials.

[0003] In existing water treatment, when adding drugs, most of them are directly added into the water treatment tank. This operation requires time for the drugs to mix with the wastewater, resulting in a slower water treatment process, reduced water treatment efficiency, and even the possibility that some wastewater is directly discharged without being mixed with the drugs. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figures 1-4 , a dosing device for water treatment, comprising a mounting plate 1, a dosing pipe 13 being provided at one end of the top of the mounting plate 1;

[0025] The present invention also includes a box 16 for water treatment. The top of the box 16 is provided with an opening, and the mounting plate 1 is installed on the box 16 corresponding to the opening. A water inlet pipe 11 is installed on one side of the top of the box 16, and a drain pipe 12 is installed at the bottom of the box 16. When in use, wastewater is added to the box 16 from the water inlet pipe 11, and then the medicine is added to the box 16 from the dosing pipe 13, so that the medicine and wastewater are mixed to perform water treatment operations, and the treated wastewater will be discharged from the drain pipe 12.

[0026] Furthermore, in order to ensure the sealing between the mounting plate 1 and the box body 16 after installation, a sealing ring is provided between the edge of the mounting plate 1 and the opening of the box body 16 , and the sealing ring is fixed on the mounting plate 1 .

[0027] It should be noted that if Figure 1 As shown, a cover plate 14 is hinged on one side of the top of the dosing tube 13, and the other side of the cover plate 14 is fixed to the dosing tube 13 by a lock. In this way, after adding medicine from the dosing tube 13, the cover plate 14 can be closed to seal the port of the dosing tube 13 to prevent the odor generated during water treatment from wafting out from the dosing tube 13.

[0028] like Figure 3 and Figure 4 As shown, a first drive motor 10 is provided at the upper middle end of the mounting plate 1, a first drive shaft 8 is installed at the bottom of the first drive motor 10, and the first drive shaft 8 passes through the mounting plate 1 and the two are rotatably connected, and a plurality of stirring blades 9 are installed on the first drive shaft 8 at intervals. Under the operation of the first drive motor 10, the wastewater mixed with the medicine in the box 16 is stirred to accelerate the mixing of the medicine and the wastewater;

[0029] Specifically, the stirring blade 9 is set at an angle. During actual use, the inclined stirring blade 9 can push the wastewater upward when rotating, and the surface of the stirring blade 9 is coated with a wear-resistant ceramic layer, which improves the wear resistance of the stirring blade 9 and thus increases the service life of the stirring blade 9.

[0030] When the stirring blade 9 stirs the wastewater, it will produce a centrifugal effect on the wastewater, causing the wastewater to flow toward the inner wall of the box body 16, and a plurality of second drive shafts 5 arranged at intervals are provided along the lower edge of the mounting plate 1. The top of the second drive shaft 5 passes through the mounting plate 1 and is rotatably connected to the mounting plate 1, and a second drive motor 7 is installed on the top of the second drive shaft 5. The second drive motor 7 is fixed on the mounting plate 1, and a spiral blade 6 is installed on the second drive shaft 5. Under the operation of the second drive motor 7, the spiral blade 6 will be driven to rotate, thereby pushing the wastewater flowing to the inner wall of the box body 16 downward, and when the wastewater flows to the bottom of the box body 16, under the limit barrier at the bottom of the box body 16, the wastewater can continue to converge along the bottom of the box body 16 to the middle of the box body 16, so that the wastewater flows in the box body 16, thereby accelerating the mixing of the wastewater and the medicine to improve the water treatment efficiency.

[0031] It should be noted that a number of spaced aeration pipes 4 are provided at the bottom of the box body 16, the ends of the aeration pipes 4 are connected to the multi-way pipe 3, and the other ends of the multi-way pipes 3 pass through the box body 16 and are connected to the air inlet pipe 2. Under the aeration action of the aeration pipes 4, the wastewater sent to the middle of the box body 16 by the spiral blades 6 can be transported upward, and the stirring blades 9 can push the wastewater toward the inner wall of the box body 16 again, thereby accelerating the circulation of the wastewater in the box body 16 and further improving the mixing of the wastewater and the medicine; even after the medicine is added again, the medicine can be mixed with the wastewater faster.

[0032] Furthermore, a pressure relief valve 15 is provided on the top of the mounting plate 1. Since the entire box body 16 and the mounting plate 1 are in a sealed state most of the time, when the wastewater is aerated, the pressure in the box body 16 continues to increase, and the pressure relief valve 15 can be used to relieve the pressure to prevent damage to the box body 16 or the mounting plate 1.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
