[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , the utility model provides a technical solution:

[0023] A water quality treatment device for irrigation area drainage, comprising a purification tank 1, a water inlet pipe 3 arranged at the top of a mixing tank 16, and a water outlet pipe 7 arranged at the top of a disinfection tank 11, wherein the purification tank 1 is provided with a mixing tank 16 for mixing flocculants; a sedimentation tank 13 (an opening is provided at the bottom of the sedimentation tank 13, and a cover is provided in the opening, which is not shown in the figure) for settling solids after flocculation; and a disinfection tank 11 (using ultraviolet disinfection, which is a prior art, which is not shown in the figure);

[0024] A hopper 4 for holding flocculants is provided at the top of the mixing tank 16, and an obstruction member is provided at the bottom of the hopper 4. The use of the obstruction member facilitates the control of the falling of the flocculants, and prevents the flocculants from falling when the reflux water does not flow in, thereby avoiding the waste of flocculants and saving resources; a mixing member is provided at the bottom of the mixing tank 16. The use of the mixing member facilitates the stirring of the reflux water in the mixing tank 16, so that the flocculants and the reflux water are evenly mixed, and the effect of flocculation of impurities in the reflux water is improved, which is beneficial to the purification of the reflux water;

[0025] A filter screen 10 is provided on the top of the disinfection tank 11 to prevent floccules in the water from flowing out; a cleaning piece is provided on the top of the purification box 1 for cleaning the filter screen 10. By using the cleaning piece, it is convenient to clean the floccules attached to the filter screen 10 to avoid clogging of the filter screen 10, thereby affecting the flow of water.

[0026] In the utility model, the obstruction member includes a push plate 15 slidably arranged on the mixing tank 16 and a sealing plate 19 arranged on one side of the push plate 15. The push plate 15 is located at the inner end of the water inlet pipe 3 and contacts the water inlet pipe 3. A circular hole 18 is opened on the sealing plate 19, and the sealing plate 19 can be used to seal the hopper 4 to prevent the flocculant from falling when not in use. After the circular hole 18 overlaps with the bottom of the hopper 4, the bottom of the hopper 4 is opened, so that the flocculant falls. An extrusion spring 9 is provided between the push plate 15 and the mixing tank 16 for resetting the push plate 15.

[0027] In the utility model, sliders (not shown in the figure) are provided on the front and rear end surfaces of the push plate 15, and a sliding groove (not shown in the figure) is provided on the inner wall of the mixing tank 16 to cooperate with the slider, which is conducive to the sliding of the push plate 15 and at the same time limits the push plate 15 to prevent the push plate 15 from moving downward.

[0028] In the utility model, the mixing element includes a connecting shaft 17 rotatably arranged at the bottom of a mixing tank 16, a plurality of stirring blades 14 are evenly arranged on the outer wall of the connecting shaft 17, and a driving motor 2 is arranged at one end of the connecting shaft 17 (the driving motor 2 can be powered by an electric energy battery panel or a battery, both of which are prior arts). The stirring blades 14 are driven by the driving motor 2 to rotate, so as to stir the reflowing water in the mixing tank 16, so that the reflowing water and the flocculant are fully mixed, which is beneficial to the purification of the reflowing water.

[0029] In the utility model, the cleaning part includes a water pump 5 arranged on the top of the purification box 1 (the water pump 5 can be powered by an electric energy battery panel or a battery, both of which are prior arts), a water pipe 3 20 arranged on the sedimentation tank 13 and a water pipe 1 6 arranged at the water inlet end of the water pump 5, and one end of the water pipe 1 6 is connected with the top of the disinfection tank 11, and the water outlet end of the water pump 5 is provided with a water pipe 2 8 connected with the water pipe 3 20, and a strip water outlet 12 is provided on the outer wall of the water pipe 3 20, and the strip water outlet 12 is parallel to the bottom surface of the filter screen plate 10.

[0030] Working principle: When the utility model is in use, the device is installed at the water inlet of the irrigation area, and the backflow water enters the mixing tank 16 through the water inlet pipe 3, and the push plate 15 is driven to move by the water impact, so that the circular hole 18 coincides with the bottom of the hopper 4, and then the flocculant in the hopper 4 falls, so as to realize the addition of flocculant to the backflow water; wherein, when there is no water entering the water inlet pipe 3, the push plate 15 is reset under the action of the extrusion spring 9, and the sealing plate 19 blocks the bottom of the hopper 4 to prevent the flocculant from falling;

[0031] When the refluxed water enters, the driving motor 2 is started, and the connecting shaft 17 is driven to rotate by the output shaft of the driving motor 2, and then the stirring blade 14 is driven to rotate, so as to stir the refluxed water in the mixing tank 16, so that the refluxed water and the flocculant are fully mixed, which is conducive to flocculation of impurities in the refluxed water, thereby facilitating the purification of the refluxed water;

[0032] Then the returned water passes through the sedimentation tank 13, and the flocculants in the returned water will settle. Then the water passes through the disinfection tank 11, and the ultraviolet rays in the disinfection tank 11 are used to disinfect the returned water. Finally, the water passes through the filter screen 10 to filter out impurities in the water, thereby separating the impurities in the water. Finally, the water flows into the irrigation area through the outlet pipe 7, which is beneficial to the protection of the water quality of the irrigation area.

[0033] When it is necessary to clean the attachments on the filter screen plate 10, turn on the water pump 5, and transport the filtered water to the water pipe 3 20 through the water pump 5, and then the water impacts the bottom surface of the filter screen plate 10 through the strip water outlet 12, so as to wash away the attachments on the bottom surface of the filter screen plate 10 and prevent the mesh of the filter screen plate 10 from being blocked, which is beneficial to the filtration of water.

[0034] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
