Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment devices, and in particular to a sewage treatment device that allows for uniform dispensing of coagulant. Background Technology

[0002] Wastewater treatment equipment has a wide range of applications, covering urban wastewater treatment plants, industrial wastewater treatment, agricultural drainage treatment, and many other fields. In urban wastewater treatment plants, wastewater treatment equipment is used to treat domestic sewage and protect the urban water environment; in industrial wastewater treatment, wastewater treatment equipment needs to be customized to meet the specific characteristics of wastewater from different industries to ensure optimal treatment results.

[0003] Existing wastewater treatment systems typically involve adding coagulants to the wastewater. Coagulants are chemical agents used in wastewater treatment equipment to coagulate and flocculate suspended particles in the wastewater. When coagulants are added to the wastewater, they produce positively charged colloidal particles through chemical reactions such as hydrolysis. Most suspended particles in wastewater are negatively charged, such as clay particles and algal cells. According to the principle of opposite charges attracting, the positively charged colloidal particles generated by the coagulant neutralize the negative charge of the suspended particles, causing them to lose stability. Once unstable, the suspended particles collide and combine, forming larger flocs. The formation of flocs facilitates subsequent sedimentation or filtration processes because larger flocs are easier to separate from the wastewater.

[0004] However, when adding coagulants, they are often placed at a fixed location in the wastewater, or manually at different locations. Manual placement requires workers to move the coagulant and walk around frequently. If the placement point is fixed, the coagulant may be unevenly distributed in the wastewater, affecting the coagulation effect. This can lead to excessively high coagulant concentrations near the placement point, causing unnecessary waste and potentially inhibiting microorganisms in the wastewater. Therefore, we propose a wastewater treatment device for uniform coagulant distribution. Utility Model Content

[0013] This invention provides a wastewater treatment device for uniform coagulant dosing, which has the following advantages compared with the prior art:

[0014] 1. This design presents a wastewater treatment device for uniform coagulant dosing. By moving the discharge pipe to different locations within the tank, the coagulant can be discharged to various points within the tank. Multi-point discharge of the coagulant allows for more thorough mixing with the wastewater, ensuring uniform dispersion throughout the tank. This helps reduce localized excessively high or low coagulant concentrations, thereby improving the coagulation effect. Furthermore, workers only need to pull the connecting rope, avoiding frequent handling and movement, thus reducing their workload.

[0015] 2. This design provides a wastewater treatment device for uniform coagulant dosing. A protective cover shields the upper end of the container, preventing external pollutants from falling into the container and thus protecting the coagulant inside.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution for a wastewater treatment device that uniformly dispenses coagulant: A wastewater treatment device that uniformly dispenses coagulant includes: a tank 1 with an open top, two symmetrically distributed slides 2 fixedly installed inside the tank 1, a container 3 positioned between the two slides 2, the container 3 having an open top, a drain pipe 4 connected and fixedly installed at the bottom of the container 3, a horizontal pipe 5 connected and fixedly installed at the bottom of the drain pipe 4, and support frames 6 fixedly installed at both ends of the horizontal pipe 5, the upper ends of the support frames 6 being fixedly connected to the container 3, the container 3 containing liquid coagulant. Multiple equidistantly distributed outlet pipes 7 are connected and fixedly installed at the bottom of the horizontal pipe 5, sliders 8 are fixedly installed at both ends of the horizontal pipe 5, the sliders 8 being slidably disposed within the slides 2, limit rods 9 fixedly installed within the slides 2, the limit rods 9 penetrating the sliders 8, a solenoid valve 10 installed on the drain pipe 4 for controlling the opening and closing of the drain pipe 4, and connecting ropes 11 fixedly connected to both ends of the horizontal pipe 5, the length of the connecting ropes 11 being longer than the length of the container 3.

[0023] Tank 1 contains wastewater. Opening the solenoid valve 10 allows liquid coagulant to drain from the drain pipe 4 to the horizontal pipe 5, and then to multiple outlet pipes 7 for further discharge, preventing coagulant discharge from a single point. Simultaneously, pulling the two connecting ropes 11 on the same side causes the horizontal pipe 5 to move slowly along the slide 2. The slider 8 slides within the slide 2, moving the horizontal pipe 5 and container 3 to different positions within tank 1, thus moving the outlet pipes 7 to different locations within tank 1. This multi-point discharge of the coagulant allows for more thorough mixing with the wastewater, ensuring uniform dispersion throughout tank 1. This helps reduce localized high or low concentrations of the coagulant, improving coagulation efficiency. Furthermore, workers only need to pull the connecting ropes 11, avoiding frequent handling and movement, thus reducing their workload.

[0024] When adding coagulant, pull the two connecting ropes 11 on the other side to move the horizontal pipe 5 to the other side of the tank 1.

[0025] The tank 1 is equipped with a liquid level scale on its exterior for easy observation and control of the amount of wastewater added. A protective cover 12 is installed at the top of the tank 1, with both ends fixedly connected to the tank 1. The protective cover 12 is located above the container 3 and covers the upper port of the container 3. By using the protective cover 12 to shield the upper port of the container 3, external pollutants are prevented from falling into the container 3, thus protecting the coagulant inside the container 3.

[0026] A first motor 13 is fixedly installed outside the tank body 1, and the output shaft of the first motor 13 extends into the tank body 1. Multiple first blades 14 are arranged inside the tank body 1, and each first blade 14 is fixedly connected to the output shaft of the first motor 13. During sewage treatment, the first motor 13 drives the multiple first blades 14 to rotate, and the first blades 14 agitate the sewage and coagulant, so that the sewage and coagulant are in full contact.

[0027] A support plate 15 is fixedly installed inside the container 3. A vertical shaft 16 is rotatably mounted on the support plate 15, and the lower end of the vertical shaft 16 extends into the container 3. Multiple second blades 17 are provided inside the container 3, and the second blades 17 are all fixedly connected to the lower end of the vertical shaft 16. A rack 18 is fixedly installed on the protective cover 12, and a gear 19 is fixedly installed on the upper end of the vertical shaft 16. The gear 19 meshes with the rack 18.

[0028] As the container 3 slides along the slide 2, the gear 19 meshes with the rack 18, and the rack 18 drives the gear 19 to rotate. The gear 19, the vertical shaft 16, and the second blade 17 rotate synchronously, which allows the second blade 17 to stir the coagulant in the container 3, thus preventing the coagulant from settling. Therefore, when using the coagulant, it can be fully stirred and dissolved.

[0029] The working principle of this invention is as follows: The tank 1 contains wastewater. When the solenoid valve 10 is opened, the liquid coagulant can be discharged from the drain pipe 4 to the horizontal pipe 5, and then discharged from multiple outlet pipes 7 at multiple points, preventing the coagulant from being discharged from a single location. Simultaneously, by pulling the two connecting ropes 11 on the same side, the connecting ropes 11 drive the horizontal pipe 5 to move slowly along the slide 2. The slider 8 slides simultaneously within the slide 2, moving the horizontal pipe 5 and the container 3 to different positions within the tank 1. This allows the outlet pipes 7 to move to different positions within the tank 1, discharging the coagulant to different locations within the tank 1. This multi-point discharge of the coagulant allows for more thorough mixing with the wastewater, ensuring that the coagulant is evenly dispersed throughout the entire tank 1.

[0030] As the container 3 slides along the slide 2, the gear 19 meshes with the rack 18, and the rack 18 drives the gear 19 to rotate. The gear 19, the vertical shaft 16, and the second blade 17 rotate synchronously, which allows the second blade 17 to stir the coagulant in the container 3, thus preventing the coagulant from settling. Therefore, when using the coagulant, it can be fully stirred and dissolved.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
