Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a wastewater treatment device with a stirring structure. Background Technology

[0002] Wastewater treatment equipment is an environmental protection device that uses physical, chemical, or biological processes to purify wastewater generated from industrial production or daily life.

[0003] However, the existing equipment has the following shortcomings: During the wastewater treatment process, after the wastewater undergoes a chemical reaction inside the tank, a large amount of solid waste (such as reaction precipitates, flocculent matter, etc.) is generated. Due to the lack of an effective pretreatment and separation mechanism, these solid wastes are prone to directly settling and accumulating on the surface of the filter plate in the tank under gravity. When the wastewater needs to be discharged through the discharge pipe, the filter plate, as the core filtration component for wastewater discharge, will have its filter holes gradually blocked by the continuously accumulated solid waste, resulting in a slowdown in the wastewater discharge flow rate. As the amount of waste accumulates, the filter holes will be completely blocked, forming a dense waste accumulation layer. This not only completely hinders the rapid discharge of wastewater, but also exacerbates the wear and corrosion of the filter plate over a long period of time, shortening the service life of the equipment and affecting the efficiency of wastewater discharge.

[0004] Therefore, we propose a wastewater treatment device with a stirring structure to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where solid waste easily accumulates on the surface of the filter plate, making it difficult for wastewater to pass through the filter plate quickly and be discharged. Therefore, this invention proposes a wastewater treatment device with a stirring structure.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a wastewater treatment device with a stirring structure, comprising a tank, a discharge pipe, a mounting frame, an inlet pipe, a stirrer, a mounting plate, and a moving device. The mounting frame is fixedly connected to the surface of the tank, the discharge pipe is fixedly connected to the lower end of the tank, the inlet pipe is fixedly connected to the outer surface of the tank, the mounting plate is mounted on the upper end of the tank, the stirrer is mounted on the surface of the mounting plate, and the moving device is installed inside the tank. The moving device includes a mounting ring and a filter plate, the filter plate being fixedly connected to the mounting frame. Inside the mounting ring, the mounting ring is installed inside the tank. A limiting ring is fixedly connected to the upper end of the mounting ring. A toothed ring is installed above the mounting ring. A limiting groove is formed on the outer surface of the toothed ring. The toothed ring is rotatably connected to the surface of the limiting ring through the limiting groove. A first gear is meshed inside the toothed ring. An mounting rod is fixedly connected inside the toothed ring. A scraper is fixedly connected to the end of the mounting rod away from the toothed ring. The scraper is rotatably connected to the upper surface of the filter plate. A protective cover is fixedly connected to the upper surface of the mounting ring. The protective cover is sleeved and connected to the surface of the toothed ring.

[0007] Furthermore, a rotating rod is fixedly connected to the upper end of the first gear, and a second gear is fixedly connected to the upper end of the rotating rod. By setting the rotating rod, power can be transmitted to drive the first gear to rotate, reducing the possibility of the first gear getting stuck during use.

[0008] Furthermore, a third gear is meshed with the side of the second gear, and a servo motor is fixedly connected to the upper surface of the third gear. The servo motor is provided to facilitate the rotation of the third gear.

[0009] Furthermore, a mounting arm is fixedly connected to the surface of the servo motor. The mounting arm is fixedly connected to the surface of the mounting plate, and the mounting arm is provided to facilitate the limiting of the servo motor.

[0010] Furthermore, an auxiliary component is fixedly provided on the surface of the rotating rod. The auxiliary component includes a connecting frame and a first positioning block. The first positioning block is fixedly connected to the surface of the rotating rod, and the connecting frame is fixedly connected to the inside of the tank. By setting the first positioning block, the rotating rod can be limited, reducing the likelihood of the rotating rod shaking when it rotates during use.

[0011] Furthermore, the connecting frame has a positioning groove inside, and the first positioning block is rotatably connected inside the positioning groove.

[0012] Furthermore, a limiting post is fixedly connected to the upper end of the protective cover, and a second positioning block is fixedly connected to the surface of the rotating rod, with the second positioning block rotatably connected inside the limiting post.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a moving device, the waste material accumulated on the surface of the filter plate is effectively moved, which plays the role of moving the waste material. This reduces the situation where, in the existing equipment, the solid waste generated after the wastewater undergoes a chemical reaction easily accumulates on the surface of the filter plate. When the wastewater after the reaction inside the tank is discharged through the discharge pipe, the waste material easily accumulates and blocks the surface of the filter plate, making it difficult to discharge the wastewater quickly. This moving device realizes the cleaning of solid waste on the surface of the filter plate and improves the wastewater discharge efficiency of the equipment.

[0014] 2. In this utility model, by setting an auxiliary component, the rotating rod is effectively limited, which plays a role in balancing the rotation of the rotating rod. This reduces the shaking that easily occurs when the rotating rod is long during the operation of existing equipment. This auxiliary component realizes the smooth rotation of the rotating rod and improves the stability of the equipment. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a wastewater treatment device with a stirring structure, including a tank 1, a discharge pipe 2, a mounting frame 3, a feed pipe 4, a stirrer 5, a mounting plate 6, and a moving device 7.

[0020] Tank 1 is welded from corrosion-resistant stainless steel, with an epoxy resin anti-corrosion coating on the inner wall to resist the corrosion of acid and alkaline wastewater and extend the service life of the equipment. The mounting frame 3 is a triangular load-bearing structure with expansion bolt fixing holes at the bottom to firmly fix tank 1 to the ground and prevent shaking during stirring. The discharge pipe 2 is equipped with a check valve to prevent backflow of wastewater after discharge. A removable filter screen is installed at the pipe opening to further intercept any leaked impurities. The feed pipe 4 is equipped with a diffusion nozzle at the end to evenly disperse the wastewater into the tank 1, preventing excessively high local wastewater concentration from affecting the reaction effect. The mounting plate 6 is connected to tank 1 by a flange, which has good sealing performance and facilitates disassembly and maintenance of internal components. The agitator 5 adopts a multi-layer blade structure with guide holes on the blade surface to enhance the stirring turbulence effect and make the wastewater and reagents mix more thoroughly.

[0021] The following section will describe in detail the specific settings and functions of its mobile device 7 and auxiliary components 8.

[0022] In this implementation scheme: The mobile device 7 is installed inside the tank 1 and is the core structure for solving the problem of filter plate 72 clogging in wastewater treatment. It can remove reaction waste residue on the surface of filter plate 72 in real time, ensuring unobstructed filtration channels and improving wastewater discharge efficiency. The mobile device 7 includes a mounting ring 71 and a filter plate 72. The filter plate 72 is fixedly connected inside the mounting ring 71. The filter plate 72 uses a high-strength stainless steel filter screen, and the mesh size can be adjusted according to the particle size of the waste residue. It has high filtration accuracy and is not easily deformed. The mounting ring 71 is installed inside the tank 1. A limit ring 73 is fixedly connected to the upper end of the mounting ring 71. A toothed ring 74 is installed above the mounting ring 71. A limit groove 75 is opened on the outer surface of the toothed ring 74. The gear ring 74 is rotatably connected to the surface of the limiting ring 73 via the limiting groove 75. The first gear 76 is meshed inside the gear ring 74. The mounting rod 77 is fixedly connected inside the gear ring 74. A scraper 78 is fixedly connected to the end of the mounting rod 77 away from the gear ring 74. The scraper 78 is made of elastic rubber and fits tightly against the surface of the filter plate 72. It can effectively scrape off waste residue without damaging the filter screen. The scraper 78 is rotatably connected to the upper surface of the filter plate 72. A protective cover 79 is fixedly connected to the upper surface of the mounting ring 71. The protective cover 79 is made of transparent acrylic material. It can prevent waste residue from splashing and contaminating the gear structure, and it is easy to observe the internal operating status. The protective cover 79 is sleeved and connected to the surface of the gear ring 74.

[0023] Specifically, a rotating rod 710 is fixedly connected to the upper end of the first gear 76. The rotating rod 710 is made of hollow stainless steel tube, which is lightweight and strong, and can reduce the inertial resistance during rotation. A second gear 711 is fixedly connected to the upper end of the rotating rod 710.

[0024] In this embodiment, by setting the rotating rod 710, power can be transmitted to drive the first gear 76 to rotate, reducing the possibility of the first gear 76 getting stuck during use.

[0025] Specifically, the second gear 711 is meshed with the third gear 712 on its side, and the upper surface of the third gear 712 is fixedly connected to the servo motor 713. The servo motor 713 is a stepper motor with a braking function, which can precisely control the rotation angle to realize intermittent or continuous cleaning of the scraper 78, adapting to different working conditions. The servo motor 713 is set to facilitate the rotation of the third gear 712.

[0026] Specifically, a mounting arm 714 is fixedly connected to the surface of the servo motor 713. The mounting arm 714 is fixedly connected to the surface of the mounting plate 6. The mounting arm 714 is provided to facilitate the limiting of the servo motor 713.

[0027] In this embodiment: an auxiliary component 8 is fixedly provided on the surface of the rotating rod 710. The auxiliary component 8 includes a connecting frame 81 and a first positioning block 82. The first positioning block 82 is fixedly connected to the surface of the rotating rod 710, and the connecting frame 81 is fixedly connected to the inside of the tank 1.

[0028] In this embodiment: by setting the first positioning block 82, the rotating rod 710 can be limited, which reduces the likelihood of the rotating rod 710 shaking when rotating during use.

[0029] Specifically, the connecting frame 81 has a positioning groove 83 inside, and the first positioning block 82 is rotatably connected inside the positioning groove 83.

[0030] Specifically, the upper end of the protective cover 79 is fixedly connected to a limiting post 84. The limiting post 84 and the protective cover 79 are connected by a thread, which facilitates height adjustment and adapts to rotating rods 710 of different lengths. A second positioning block 85 is fixedly connected to the surface of the rotating rod 710, and the second positioning block 85 is rotatably connected inside the limiting post 84.

[0031] Working Principle: During operation, the user introduces wastewater into the tank 1 through the feed pipe 4. The agitator 5 is then activated to thoroughly mix the wastewater and chemicals (such as flocculants and oxidants) inside the tank 1. The rotation speed of the agitator 5 can be adjusted from 50-300 rpm via a motor, creating a turbulent environment that increases the contact area between the wastewater and chemicals by more than 30%, accelerating the chemical reaction and generating waste. This waste easily accumulates on the surface of the filter plate 72. The servo motor 713 then drives the third gear 712 to rotate. Through gear meshing, this drives the second gear 711 and the rotating rod 710 to rotate, which in turn drives the first gear 76 to rotate. The first gear 76 meshes with the gear ring 74, driving the gear ring 74 through the limiting groove 75. The upper limit ring 73 of the mounting ring 71 rotates, and the mounting rod 77 inside the toothed ring 74 drives the scraper 78 to rotate synchronously, moving the waste on the surface of the filter plate 72. By setting the moving device 7, the waste accumulated on the surface of the filter plate 72 is effectively moved, which plays the role of moving waste. This reduces the situation where solid waste generated after the chemical reaction of wastewater tends to accumulate on the surface of the filter plate 72 when the wastewater after the reaction inside the tank 1 is discharged through the discharge pipe 2, and the waste easily accumulates and blocks the surface of the filter plate 72, making it difficult to discharge the wastewater quickly. This moving device 7 realizes the cleaning of solid waste on the surface of the filter plate 72 and improves the wastewater discharge efficiency of the equipment.

[0032] When the equipment rotates the rotating rod 710, the first positioning block 82 and the second positioning block 85 on the surface of the rotating rod 710 rotate inside the connecting frame 81 and the limiting post 84, limiting the rotation of the rotating rod 710. By setting the auxiliary component 8, the rotating rod 710 is effectively limited, which plays a role in balancing the rotation of the rotating rod 710. This reduces the shaking that is prone to occur when the rotating rod 710 is long during the operation of the existing equipment. This auxiliary component 8 realizes the smooth rotation of the rotating rod 710 and improves the stability of the equipment.

[0033] The above description discloses only one or more preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
