Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for environmental protection. Background Technology

[0002] Wastewater is wastewater discharged from industry and daily life that has been polluted to a certain extent. If wastewater is not thoroughly treated before discharge, the heavy metal ions and pollutants it contains will pollute the external environment. Wastewater treatment refers to the process of making discharged wastewater meet the water quality requirements of being pollution-free or reusable. Wastewater treatment is widely used in various fields such as agriculture, industry, medical care, and catering.

[0003] Currently, existing technology CN213569857U discloses a wastewater treatment device for environmental protection, including a box body. The box body has an inlet at the top and an outlet on the bottom side wall. A screw is located at the upper end of the box body, and a slider is fitted around the screw. The slider has a through hole at its upper end, and a sliding rod is inserted through the through hole. Both ends of the sliding rod are fixedly connected to the inner wall of the box body. A scraper is connected to the bottom end of the slider. A filter screen is also provided inside the box body, with the upper surface of the scraper and the filter screen in contact. A slag discharge port is located on the side wall of the box body, at the same horizontal level as the scraper. A collection box is suspended on the side wall of the box body, located below the slag discharge port. This wastewater treatment device for environmental protection can clean impurities clogging the filter screen during wastewater treatment, thus improving wastewater filtration efficiency.

[0004] However, in the aforementioned wastewater treatment device for environmental protection, the stirring rod can only stir the wastewater at the bottom of the tank, while the disinfectant drips in from the bottom of the placement rack. If the wastewater flow is large, some of the disinfectant may not be fully mixed with the wastewater before being discharged from the outlet, affecting the disinfection effect. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment device for environmental protection, which aims to solve the problem that the existing wastewater treatment devices for environmental protection do not mix the reagents and wastewater sufficiently, thus affecting the disinfection effect of the wastewater.

[0006] To achieve the above objectives, this utility model provides a wastewater treatment device for environmental protection, comprising a wastewater tank body, a filtration mechanism, and a disinfection component. The filtration mechanism is disposed on one side of the wastewater tank body. The disinfection component includes a pad, a stirring mechanism, a delivery pipe, a diversion pipe, and a reagent tank. The pad is fixedly connected to the wastewater tank body and located at the bottom of the wastewater tank body. The stirring mechanism is assembled at the bottom of the wastewater tank body. The reagent tank is fixedly connected to the wastewater tank body and located on the outer wall of the wastewater tank body. The delivery pipe communicates with the wastewater tank body and is located on both sides of the wastewater tank body. The diversion pipe communicates with the reagent tank and is connected to the delivery pipe, and is located between the delivery pipe and the reagent tank.

[0007] The stirring mechanism includes a main stirring rod, a secondary stirring rod, a drive motor, and a drive gear set. The drive motor is mounted on the bottom of the sewage tank body. The main stirring rod is fixedly connected to the output end of the drive motor and passes through the sewage tank body. The secondary stirring rod is mounted on one side of the sewage tank body. The drive gear set is mounted on the main stirring rod and the secondary stirring rod.

[0008] The drive gear set includes a driving gear and a driven gear. The driving gear is fixedly connected to the main stirring rod and is located outside the main stirring rod. The driven gear is fixedly connected to the auxiliary stirring rod and meshes with the driving gear, and is located outside the auxiliary stirring rod.

[0009] The drug delivery tube has a one-way valve, which is installed inside the drug delivery tube.

[0010] The disinfection component includes a connecting buckle, which is fixedly connected to the sewage tank body and snapped into the drug delivery pipe, and is located on the outside of the sewage tank body.

[0011] This utility model discloses a wastewater treatment device for environmental protection. Domestic sewage enters the wastewater tank body through a discharge pipe. First, it passes through a filtration mechanism to remove large particulate impurities. The sewage then falls below the wastewater tank body (refer to patent CN213569857U for the wastewater tank body and the filtration mechanism). At this time, the controller opens the diversion pipe (a control valve, not shown in the figure, is installed on the diversion pipe). The diversion pipe diverts the disinfectant solution in the reagent tank and introduces it into the delivery pipe. Multiple delivery pipes are evenly distributed on both sides of the wastewater tank body. The delivery pipes introduce the disinfectant into both sides of the wastewater tank body, thus injecting the disinfectant at multiple locations. Simultaneously, the stirring mechanism rotates, mixing the wastewater and disinfectant in multiple directions to ensure uniform mixing. The pad is used to elevate the wastewater tank body, providing space for the stirring mechanism, thereby solving the problem of insufficient mixing of disinfectant and wastewater in existing wastewater treatment devices for environmental protection, which affects the disinfection effect.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1 to 4 This utility model provides a wastewater treatment device for environmental protection, including a wastewater tank body 1, a filtration mechanism 2, and a disinfection component 3. The filtration mechanism 2 is disposed on one side of the wastewater tank body 1. The disinfection component 3 includes a pad 31, a stirring mechanism 32, a drug delivery pipe 33, a diversion pipe 34, and a reagent tank 35. The pad 31 is fixedly connected to the wastewater tank body 1 and is located at the bottom of the wastewater tank body 1. The stirring mechanism 32 is assembled at the bottom of the wastewater tank body 1. The reagent tank 35 is fixedly connected to the wastewater tank body 1 and is located on the outer wall of the wastewater tank body 1. The drug delivery pipe 33 communicates with the wastewater tank body 1 and is located on both sides of the wastewater tank body 1. The diversion pipe 34 communicates with the reagent tank 35 and the drug delivery pipe 33, and is located between the drug delivery pipe 33 and the reagent tank 35.

[0020] In this embodiment, domestic sewage enters the sewage tank body 1 through the sewage pipe, first passing through the filter mechanism 2 to remove large particulate impurities. The sewage then passes through the filter mechanism 2 and falls below the sewage tank body 1 (for the sewage tank body 1 and the filter mechanism 2, please refer to patent CN213569857U). At this time, the controller then opens the diversion pipe 34 (the diversion pipe 34 is equipped with a control valve, not shown in the figure), and the diversion pipe 34 diverts the disinfectant solution in the medicine tank 35 and introduces it into the delivery pipe 33. The drug delivery pipes 33 are multiple and evenly distributed on both sides of the sewage tank body 1. The drug delivery pipes 33 introduce the agent into both sides of the sewage tank body 1, thereby injecting the agent at multiple locations. At the same time, the stirring mechanism 32 rotates and stirs and mixes the sewage and the agent in multiple directions, so that the agent and the sewage are evenly mixed. The pad block 31 is set to raise the sewage tank body 1 and provide space for the stirring mechanism 32 to be installed, thereby solving the problem that the agent and sewage are not sufficiently mixed in existing environmental protection sewage treatment devices, which affects the sewage disinfection effect.

[0021] Furthermore, the stirring mechanism 32 includes a main stirring rod 321, a secondary stirring rod 322, a drive motor 333, and a drive gear set 334. The drive motor 333 is mounted on the bottom of the sewage tank body 1. The main stirring rod 321 is fixedly connected to the output end of the drive motor 333 and passes through the sewage tank body 1. The secondary stirring rod 322 is mounted on one side of the sewage tank body 1. The drive gear set 334 is mounted on the main stirring rod 321 and the secondary stirring rod 322.

[0022] In this embodiment, the drive motor 333 is started by the controller, driving the main stirring rod 321 to rotate clockwise, thereby stirring the sewage and chemicals in the sewage tank body 1 clockwise. At the same time, the rotation of the main stirring rod 321, under the action of the drive gear set 334, drives the auxiliary stirring rod 322 to rotate counterclockwise, thereby stirring the sewage and chemicals in the sewage tank body 1 counterclockwise. In this embodiment, the sewage and chemicals are mixed from two different directions by the main stirring rod 321 and the auxiliary stirring rod 322, which results in a better mixing effect and more thorough mixing compared to traditional single-direction mixing.

[0023] Furthermore, the drive gear set 334 includes a driving gear 3341 and a driven gear 3342. The driving gear 3341 is fixedly connected to the main stirring rod 321 and is located outside the main stirring rod 321. The driven gear 3342 is fixedly connected to the auxiliary stirring rod 322 and meshes with the driving gear 3341, and is located outside the auxiliary stirring rod 322.

[0024] In this embodiment, the rotation of the main stirring rod 321 drives the rotation of the drive wheel 3341 mounted thereon, the rotation of the drive wheel 3341 drives the rotation of the driven wheel 3342, and the rotation of the driven wheel 3342 drives the rotation of the auxiliary stirring rod 322.

[0025] Furthermore, the drug delivery tube 33 has a one-way valve 36, which is installed inside the drug delivery tube 33.

[0026] In this embodiment, the one-way valve 36 is provided to allow the drug delivery pipe 33 to be open in one direction, thereby preventing sewage from the sewage tank body 1 from entering the drug delivery pipe 33 and contaminating the drug delivery pipe 33.

[0027] Furthermore, the disinfection component 3 includes a connecting buckle 37, which is fixedly connected to the sewage tank body 1 and snapped into the drug delivery pipe 33, and is located on the outside of the sewage tank body 1.

[0028] In this embodiment, the connecting buckle 37 is provided to secure the diversion pipe 34 to the side arm of the sewage tank body 1, so as to prevent the diversion pipe 34 from swinging and falling off when introducing medicine into the medicine delivery pipe 33.

[0029] The above-disclosed embodiments are merely preferred embodiments of a wastewater treatment device for environmental protection, and should not be construed as limiting the scope of the present application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of the present application, still fall within the scope of the present application.
