Description

Technical Field

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

[0002] In wastewater treatment projects, the chemical spraying process has long faced the pain points of "high loss and low uniformity," and traditional machinery lacks flexibility to adapt to the objects being treated.

[0003] Currently, wastewater treatment agent spraying still uses a fixed discharge rate and rigid pipeline open-loop mode, failing to consider the impact of water flow pulsation and liquid surface disturbance on agent distribution. This leads to uneven mixing of agents and wastewater, localized over- or under-mixing, and treatment efficiency fluctuations exceeding 30%. Drawing inspiration from the integrated "buffering-clamping-follow-up" concept of transplanting devices, there is an urgent need for a spraying device that can adapt to the liquid surface state in real time, flexibly transport and uniformly disperse agent particles. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment agent spraying device for wastewater treatment, which solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a sewage treatment agent spraying device for sewage treatment, including a trolley, a water tank fixedly connected to the top of the trolley, and an automatic water adding and stirring device installed on the top of the water tank. The automatic water-adding and stirring device includes a mounting plate. The bottom of the mounting plate is fixedly connected to the top of the trolley. A motor is fixedly connected to the side of the mounting plate. A first belt shaft is fixedly connected to the output shaft of the motor. A belt is provided on the circumferential surface of the first belt shaft. A gear shaft is rotatably connected through the top of the water tank. A second belt shaft is fixedly connected to the circumferential surface of the gear shaft. The first belt shaft is connected to the belt drive via the second belt shaft. A driving gear is fixedly connected to the circumferential surface of the gear shaft. A gear pump box is rotatably connected to the outer surface of the driving gear. A driven gear is rotatably connected inside the gear pump box. A rotating shaft is fixedly connected to one end of the motor output shaft. A rotating sleeve is fixedly connected to the circumferential surface of the rotating shaft. A stirring rod is fixedly connected to the circumferential surface of the rotating sleeve.

[0006] Furthermore, a water delivery pipe is fixedly connected to the side of the gear pump box, and a water suction pipe is fixedly connected to the side of the gear pump box. This design facilitates the automatic intake and delivery of water. Through the meshing transmission of the driving gear and the driven gear in the gear pump box, a stable pressure difference is formed to ensure that the sewage treatment agent and water are mixed evenly.

[0007] Furthermore, the driving gear and the driven gear mesh with each other, and the driving gear and the driven gear have the same number of teeth. This design helps to ensure the smoothness of the transmission within the gear pump box, making the water flow and the delivery of the medicine more stable and reliable.

[0008] Furthermore, the number of stirring rods is set to several and arranged linearly on the circumference of the rotating shaft. A connecting plate is fixedly connected to the top of the gear pump box. The side of the connecting plate passes through and is rotatably connected to one end of the gear shaft. This design is beneficial to enhance the mixing effect of the water flow in the water tank. The multiple stirring rods effectively expand the water flow disturbance range and can eliminate the stratification phenomenon that is easy to occur in traditional devices.

[0009] Furthermore, a consolidating stirring device is provided on the circumferential surface of the rotating shaft. The consolidating stirring device includes a connecting sleeve, the inner side of which is fixedly connected to the circumferential surface of the rotating shaft. A protective shell is fixedly connected to the circumferential surface of the connecting sleeve, and a spring is fixedly connected to the inner side of the protective shell. An extension rod is fixedly connected to one end of the spring, and a scraper is fixedly connected to the side of the extension rod. A treatment agent mixing tank is fixedly connected to the top of the trolley, and a filter box is fixedly connected to the bottom inner side of the treatment agent mixing tank. This design helps to further enhance the uniformity of mixing between the agent and the wastewater. The consolidating stirring device, through the elastic cooperation of the spring and the extension rod, ensures that the scraper always adheres to the surface of the filter box, which can both remove solid particles attached to the filter box and prevent clogging that affects the efficiency of agent passage.

[0010] Furthermore, the side of the scraper abuts against the side of the filter box, and the side of the filter box is located on the displacement trajectory of the scraper. This design helps to ensure that the scraper can continuously scrape the surface of the filter box in all directions under the drive of the rotating shaft, effectively preventing solid impurities in the agent from accumulating in the filter box.

[0011] Furthermore, a spray pipe is fixedly connected to the circumference of the treatment agent mixing tank, and a regulating valve is provided on the side of the spray pipe. This design is advantageous. The amount of chemicals sprayed can be flexibly controlled according to the actual sewage treatment needs. The flow rate of chemicals flowing out of the spray pipe per unit time can be adjusted by adjusting the opening degree of the regulating valve.

[0012] This utility model has the following beneficial effects: This invention achieves automatic mixing of wastewater treatment agent and water by setting up an automatic water-adding and stirring device. The device uses the linkage between the motor-driven belt shaft and the gear shaft to drive the active gear and driven gear in the gear pump box to mesh and form a stable pressure difference, ensuring that the water and the agent are mixed evenly in proportion. This effectively solves the problem of agent waste or poor treatment effect caused by inaccurate manual proportioning in traditional spraying devices. At the same time, the introduction of the automatic water-adding and stirring device also greatly reduces the labor intensity of operators and improves the overall automation level of the operation.

[0013] This invention further enhances the uniformity of mixing between the agent and the wastewater by setting up a reinforcing stirring device. This device utilizes the elastic cooperation of a spring and an extension rod to ensure that the scraper always adheres to the surface of the filter box, effectively removing solid particles attached to the filter box. This invention also features an adjustable spray pipe and regulating valve, which allows for flexible control of the agent spraying amount according to actual wastewater treatment needs, avoiding waste caused by excessive spraying of agents and greatly improving the efficiency and effectiveness of wastewater treatment.

This design is conducive to realizing the automatic suction and delivery of water. Through the meshing transmission of the driving gear 307 and the driven gear 309 in the gear pump box 308, a stable pressure difference is formed to ensure that the sewage treatment agent and water are mixed evenly.

[0019] As shown in the figure, the driving gear 307 and the driven gear 309 mesh with each other. The driving gear 307 and the driven gear 309 have the same number of teeth. This design helps to ensure the smoothness of the transmission in the gear pump box 308, making the water flow and the delivery of the medicine more stable and reliable.

[0020] As shown in the figure, there are several stirring rods 312 arranged in a linear array on the circumference of the rotating shaft 310. A connecting plate 6 is fixedly connected to the top of the gear pump box 308. The side of the connecting plate 6 passes through and is rotatably connected to one end of the gear shaft 305. This design is beneficial to enhance the mixing effect of the water flow in the water tank 2. The multiple stirring rods 312 effectively expand the water flow disturbance range and eliminate the stratification phenomenon that is easy to occur in traditional devices.

[0021] As shown in the figure, a consolidating stirring device 7 is provided on the circumferential surface of the rotating shaft 310.

[0022] As shown in the figure, the side of the scraper 705 abuts against the side of the filter box 707, and the side of the filter box 707 is located on the displacement trajectory of the scraper 705.

[0023] As shown in the figure, a spray pipe 8 is fixedly connected to the circumference of the treatment agent mixing tank 706, and a regulating valve 9 is provided on the side of the spray pipe 8.

[0024] One specific application of this embodiment is: When motor 302 is started, the output shaft of motor 302 drives belt shaft 303 to rotate. Since belt shaft 303 is connected to belt shaft 306 via belt 304, and belt shaft 306 is fixed on gear shaft 305, gear shaft 305 will rotate accordingly. When gear shaft 305 rotates, the driving gear 307 fixedly connected to its circumference will also rotate. The driving gear 307 meshes with the driven gear 309 in gear pump box 308, thereby driving the driven gear 309 to rotate. During the meshing transmission process of driving gear 307 and driven gear 309, a stable pressure difference will be formed in gear pump box 308. At this time, water suction pipe 5 will draw water from water tank 2 into gear pump box 308, and then mix and transport the water with sewage treatment agent through water delivery pipe 4. This realizes the automatic mixing of sewage treatment agent and water, solving the problem of agent waste or poor treatment effect caused by inaccurate manual mixing in traditional spraying devices. It also reduces the labor intensity of operators and improves the overall automation level of the operation.

[0025] The output shaft of motor 302 also drives the rotating shaft 310 to rotate. Multiple stirring rods 312 arranged linearly on the rotating shaft 310 rotate accordingly. When the rotating shaft 310 rotates, the connecting sleeve 701 in the reinforcing stirring device 7 drives the protective shell 702 to rotate. The spring 703 inside the protective shell 702 and the extension rod 704 elastically cooperate to keep the scraper 705 always in contact with the surface of the filter box 707, scraping the surface of the filter box 707 in all directions, removing solid particles attached to the filter box 707, preventing blockage and affecting the efficiency of the agent passage, and further enhancing the uniformity of the mixing of the agent and the sewage. The spray pipe 8, which is circumferentially connected and fixedly connected to the treatment agent mixing tank 706, has a regulating valve 9 on its side, which can flexibly control the amount of agent sprayed according to the actual sewage treatment needs. By adjusting the opening degree of the regulating valve 9, the flow rate of the agent flowing out of the spray pipe 8 per unit time can be adjusted, avoiding waste caused by excessive spraying of the agent, and greatly improving the efficiency and effect of sewage treatment.
