Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment devices, in particular to a wastewater treatment device for environmental protection projects. Background Art

[0002] Environmental protection engineering, also known as environmental protection engineering, refers to a series of engineering projects that use knowledge and technical means from science, engineering and other related disciplines to implement environmental protection and improvement. The main purpose of these projects is to reduce environmental pollution, protect natural resources, enhance the sustainability of ecosystems, and ensure that environmental quality is not damaged during the rapid industrialization and urbanization process.

[0003] Among them, wastewater treatment is an item in environmental protection projects. When treating wastewater, it is generally necessary to use a wastewater treatment device. When treating wastewater, in order to facilitate the removal of small particle impurities in the wastewater, it is generally promoted by adding liquid medicine to promote the aggregation of fine suspended particles in the wastewater to form larger flocs, which is convenient for subsequent sedimentation or flotation process removal. This process can effectively reduce the suspended solids and turbidity in the water. When the existing wastewater treatment device is removing impurities from the wastewater, it generally directly passes the wastewater into the treatment barrel through a pipe, and then adds the liquid medicine into the treatment barrel through a pipe. Since the wastewater and the liquid medicine are directly output through the pipe during the process of passing into the treatment barrel and flow out in the form of a water column, there is a problem of weak dispersion when passing in, which affects the uniform mixing of the wastewater and the liquid medicine to a certain extent.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with specific embodiments.

[0020] like Figure 1-Figure 4 As shown, it includes a processing barrel 1 and a plurality of liquid inlet pipes 14, the side wall of the processing barrel 1 is fixedly connected with a liquid outlet pipe 12, a valve is installed on the liquid outlet pipe 12, the bottom of the processing barrel 1 is fixedly connected with a miscellaneous outlet pipe 15, a valve is installed on the miscellaneous outlet pipe 15, a stirring device is installed on the processing barrel 1, a rotating end is provided in the stirring device, a large gear 3 is fixedly sleeved on the rotating end, a plurality of transmission devices are circumferentially arranged on the large gear 3, a conical guide frame 2 is connected to the bottom of the transmission device, a plurality of water outlet holes are opened on the conical guide frame 2, a plurality of liquid inlet pipes 14 are fixedly installed on the processing barrel 1, the bottoms of the plurality of liquid inlet pipes 14 are respectively facing the plurality of conical guide frames 2, and when the rotating end rotates, the plurality of conical guide frames 2 rotate;

[0021] The stirring device includes a motor 4, a rotating rod 5 and a plurality of stirring members. The rotating rod 5 is rotatably connected to the treatment barrel 1. The large gear 3 is fixedly sleeved on the rotating rod 5. A plurality of stirring members are installed on the rotating rod 5. The motor 4 is fixedly installed on the top of the treatment barrel 1, and the output end of the motor 4 is fixedly connected to the top of the rotating rod 5. The stirring member includes a mounting frame 7 and a plurality of stirring plates 6. One end of the mounting frame 7 is fixedly installed on the rotating rod 5. The plurality of stirring plates 6 are equidistantly distributed and fixedly connected to the side wall of the mounting frame 7. Through holes are provided on the plurality of stirring plates 6. The through holes on two adjacent stirring plates 6 are staggered. The rotating rod 5 is driven to rotate by the motor 4, and the plurality of stirring plates 6 are driven to rotate by the rotating rod 5. The stirring plates 6 are used to stir the liquid, thereby further promoting the mixing of the wastewater and the liquid medicine. Since the through holes on the two adjacent stirring plates 6 are staggered, the liquid removed from the through hole of one stirring plate 6 can hit the side wall of the other stirring plate 6, which is beneficial to the dispersion of the liquid and enhances the flocculation effect.

[0022] The transmission device includes a pinion 8 and a rotating ring 10. The rotating ring 10 is rotatably connected to the top wall of the inner cavity of the treatment barrel 1. The bottom of the rotating ring 10 is fixedly connected to the pinion 8 through the first support rod 9. The bottom of the pinion 8 is fixedly connected to the conical guide frame 2 through the second support rod 11. The liquid inlet pipe 14 is inserted into the inner side of the rotating ring 10 and the pinion 8. When the rotating rod 5 rotates, the large gear 3 rotates, and the rotation of the large gear 3 drives multiple small gears 8 to rotate. The small gear 8 drives the conical guide frame 2 to rotate through the second support rod 11. When wastewater or liquid medicine is added through the liquid inlet pipe 14, it flows out from the bottom of the liquid inlet pipe 14 and hits the conical guide frame 2. Part of the liquid will flow out along the water outlet of the conical guide frame 2, and part of the liquid will move out along the edge of the conical guide frame 2 under the action of the rotation of the conical guide frame 2, which is beneficial to the dispersion of the liquid and the mixing of the wastewater and the liquid medicine.

[0023] A plurality of scraper frames 13 are fixedly mounted on the side wall of the rotating rod 5. The side walls of the scraper frames 13 fit the inner cavity side walls of the processing barrel 1. The rotation of the rotating rod 5 drives the side walls of the scraper frames 13 to rotate along the inner wall of the processing barrel 1, so as to scrape off particles attached to the inner wall of the processing barrel 1.

[0024] The working principle provided by the utility model is as follows: when the device is used, the motor 4 drives the rotating rod 5 to rotate, and the rotating rod 5 drives multiple stirring plates 6 to rotate. When the rotating rod 5 rotates, the large gear 3 rotates, and the rotation of the large gear 3 drives multiple small gears 8 to rotate. The small gear 8 drives the conical guide frame 2 to rotate through the second support rod 11. When wastewater or liquid medicine is added through the liquid inlet pipe 14, it flows out from the bottom of the liquid inlet pipe 14 and hits the conical guide frame 2. Part of the liquid will flow out along the water outlet of the conical guide frame 2, and part of the liquid will flow out along the conical guide frame 2 under the action of the rotation of the conical guide frame 2. The edge of the frame 2 is moved out, which is beneficial to the dispersion of the liquid, the mixing of the wastewater and the liquid medicine, and the formation of flocs. In addition, when the rotating rod 5 rotates, the liquid is stirred by the stirring plate 6, which further promotes the mixing of the wastewater and the liquid medicine. Since the through holes on the two adjacent stirring plates 6 are staggered, the liquid moved out from the through hole of one of the stirring plates 6 can collide with the side wall of the other stirring plate 6, which is beneficial to the dispersion of the liquid and enhances the flocculation effect. In actual operation, the liquid medicine is added first, and then the wastewater is introduced. The continuously flowing wastewater continuously collides with the liquid medicine, which is convenient for mixing. The flocculated particles can be discharged from the outlet pipe 15.
