Description

Technical Field

[0001] This utility model relates to a wastewater treatment dosing device, belonging to the field of wastewater treatment technology. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction and agriculture.

[0003] To achieve precise and efficient dosing and meet the needs of different wastewater treatment processes, dosing devices are used, which are widely applied in various wastewater treatment plants and related wastewater treatment scenarios.

[0004] In wastewater treatment, the dosing process plays a crucial role in removing pollutants and regulating water quality. However, existing wastewater treatment dosing devices have many shortcomings, seriously affecting the treatment effect and cost control. Solid wastewater treatment agents are usually in powder or granular form and need to be dissolved in water before use. In traditional wastewater treatment dosing devices, the agents may be directly added to the wastewater in the form of large particles, resulting in the agents not dissolving quickly and fully. This leads to insufficient reaction between the agents and the wastewater, affecting the wastewater treatment effect and failing to meet the expected treatment standards. To address these issues, we provide a wastewater treatment dosing device. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a wastewater treatment dosing device, the specific technical solution of which is as follows:

[0006] A wastewater treatment dosing device includes a square cylinder, a pretreatment hopper connected to the upper surface of the square cylinder, a grinding assembly installed inside the pretreatment hopper, a stirring assembly installed inside the square cylinder, a screen fixedly connected to the bottom surface of the pretreatment hopper, a drive motor mounted on the front of the pretreatment hopper, a drive shaft fixedly connected to the output end of the drive motor, multiple connecting rods connected to the outer surface of the drive shaft, a grinding roller connected to the outer surface of the multiple connecting rods, multiple grinding protrusions provided on the outer surface of the grinding roller, a support plate installed on the right side of the square cylinder, a pump body installed on the upper surface of the support plate, the input end of the pump body connected to the square cylinder through a water guide pipe, the output end of the pump body connected to a water storage tank through a water supply pipe, and multiple dosing nozzles connected to the outer surface of the water storage tank.

[0007] Preferably, a scraper is fixedly connected to the outer surface of the grinding roller, and the scraper is in contact with the screen cover.

[0008] Preferably, the stirring assembly includes a motor installed on the right side of the square cylinder, the output end of the motor is connected to a circular rod, and multiple stirring blades and multiple dispersing rods are fixedly connected to the outer surface of the circular rod.

[0009] Preferably, a plurality of support rods are fixedly connected to the upper surface of the support plate, and the top end of each support rod is connected to the outer surface of the water storage tank.

[0010] Preferably, a liquid level mark is provided on the front of the square cylinder, and an injection pipe is provided on the left side of the square cylinder.

[0011] Preferably, the bottom surface of the square cylinder is connected to a mounting base, the upper surface of the pretreatment hopper is provided with a dosing hopper, and a filter screen is fixedly connected to the inner wall of the square cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This wastewater treatment dosing device uses a grinding assembly inside the pretreatment hopper. A drive motor rotates the drive shaft, connecting rod, and grinding roller. The grinding protrusions on the surface of the grinding roller grind the chemicals added to the pretreatment hopper, crushing larger particles into smaller ones. This increases the contact area between the chemicals and the water, allowing for faster and more complete dissolution and reaction of the chemicals in subsequent treatment processes. Furthermore, the scraper plate contacts the screen cover, promptly scraping off the ground chemicals and screening them through the screen cover to prevent chemical residue and clogging, thus ensuring the effectiveness and efficiency of pretreatment.

[0014] This wastewater treatment dosing device uses a pump to draw a uniformly mixed medicated liquid from a square cylinder through a water pipe, then transports it to a storage tank via a water delivery pipe. Finally, multiple dosing nozzles on the outer surface of the storage tank dispense the medicated liquid into the wastewater treatment system. This allows for precise dosing, controlling the dosage and placement location according to the actual wastewater treatment needs, thereby improving the utilization rate of the chemicals.

Through the grinding assembly 9 in pretreatment hopper 5, the drive motor 901 drives the drive shaft 902, connecting rod 903 and grinding roller 904 to rotate. The grinding protrusion 905 on the surface of grinding roller 904 can grind the agent put into pretreatment hopper 5, crushing larger particles of agent into fine particles, increasing the contact area between agent and water, which is conducive to faster and more complete dissolution and reaction of agent in subsequent treatment process.

[0024] A scraper 11 is fixedly connected to the outer surface of the grinding roller 904, and the scraper 11 is in contact with the screen cover 8. The contact between the scraper 11 and the screen cover 8 can promptly scrape off the ground agent and pass it through the screen cover 8, avoiding agent residue and clogging, and ensuring the effect and efficiency of pretreatment. The stirring assembly 10 includes a motor 101 installed on the right side of the square cylinder 1. The output end of the motor 101 is connected to a circular rod 102. Multiple stirring blades 103 and multiple dispersing rods 104 are fixedly connected to the outer surface of the circular rod 102. The motor 101 drives the circular rod 102 to rotate. The stirring blades 103 and dispersing rods 104 on the circular rod 102 can fully stir and disperse the water and agent entering the square cylinder 1. The stirring blades 103 make the water and agent circulate in the square cylinder 1, promoting the mixing of the two. The dispersing rods 104 can further break up any possible agent clumps or large sewage impurities, making the agent and sewage mix more evenly and improving the sewage treatment effect.

[0025] Multiple support rods 15 are fixedly connected to the upper surface of the support plate 7. The top of each support rod 15 is connected to the outer surface of the water storage cylinder 16.

The dosing hopper 6 is set on the upper surface of the pretreatment hopper 5 for easy addition of medicine.

[0026] The working principle of this utility model is as follows:

[0027] In use, the device is installed at the designated location. Before wastewater treatment, the required chemicals are added to the pretreatment hopper 5 through the dosing hopper 6, and water is added through the injection pipe 4. Simultaneously, the drive motor 901 is started, rotating the drive shaft 902. The rotation of the drive shaft 902 causes the connecting rod 903 and the grinding roller 904 to rotate, thereby rotating the grinding roller 904 and the grinding convex 905 to grind the added chemicals. This is used in conjunction with the screen cover 8 and the scraper 11. The screen cover 8 allows the chemicals that meet the grinding requirements to fall below, while chemicals that do not meet the requirements continue to be ground, and the scraper... The material plate 11 can scrape off the ground medicine in time to avoid blockage. Then, the motor 101 is started and runs, which drives the circular rod 102 to rotate. When the circular rod 102 rotates, it drives multiple stirring blades 103 and dispersing rods 104 to rotate, thereby fully stirring and dispersing the medicine and water, making the medicine and water more evenly mixed. Finally, the pump body 12 is started and runs, which draws the mixed liquid containing medicine through the water guide pipe 13, and releases the liquid into the sewage treatment system through multiple dosing nozzles 17 on the outer surface of the water storage tank 16, thus completing the dosing operation.
