Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] In existing automatic dosing metering pumps, the dosage needs to be controlled by metering equipment during the dosing process. However, traditional metering uses the pump body structure for measurement. This metering equipment is not a professional metering tool and cannot control the amount of chemicals added for different wastewater treatments. In addition, the error generated during the metering process is relatively large, which affects the effect of use. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic dosing metering pump for sewage treatment, which solves the problem that traditional metering relies on the pump body structure for measurement. This metering device is not a professional metering tool and cannot control the amount of chemicals added for different sewage treatments. At the same time, it also addresses the problem of large errors generated during the metering process.

[0005] To achieve the above objectives, an automatic dosing metering pump for wastewater treatment is provided, comprising: a wastewater tank, a metering pump body, a chemical pump, and a chemical tank. A support frame is fixedly connected to the top of one side of the wastewater tank, and the chemical pump is fixedly connected to the top of the support frame.

[0024] Reference Figure 1-4 This utility model discloses an automatic dosing metering pump for sewage treatment, comprising: a sewage tank 1, a metering pump body 3, a chemical pump 5, and a chemical tank 7. A support frame 8 is fixedly connected to the top of one side of the sewage tank 1, and the chemical pump 5 is fixedly connected to the top of the support frame 8. A discharge pipe 2 is fixedly connected to the output end of the chemical pump 5, and an inlet pipe 6 is fixedly connected to the input end of the chemical pump 5. The chemical pump 5 pumps the chemicals inside the chemical tank 7 through the inlet pipe 6 to the discharge pipe 2, thereby performing chemical dosing treatment on the sewage tank 1. The metering pump body 3 is fixedly connected to the middle of the discharge pipe 2, and a feed roller 4 is rotatably connected inside the metering pump body 3. The dosing amount is calculated based on the number of rotations of the feed roller 4. The feed roller 4 has a turntable 10 fixedly connected to one end. When the feed roller 4 rotates, it can synchronously rotate the turntable 10, which will drive the rotation of the equidistant contact rods 11. Several equidistant contact rods 11 are fixedly connected inside the turntable 10. A metering device 12 is set on the outside of one of the equidistant contact rods 11. A fixed seat 14 is fixedly connected to the outside of the metering device 12. The fixed seat 14 is fixedly connected to the sewage tank 1. An arc-shaped groove is opened on the outside of the feed roller 4. When the medicine flows into the inside of the metering pump body 3, it can be driven by the drive motor 9 to drive the feed roller 4 to rotate. The several arc-shaped grooves on the outside of the feed roller 4 facilitate the storage of medicine.

[0025] A drive motor 9 is fixedly connected to the other side of the metering pump body 3. The drive motor 9 drives the feed roller 4 to rotate, so that the medicine can be flipped over from above and fall to the bottom of the metering pump body 3, and discharged through the medicine outlet pipe 2. The drive end of the drive motor 9 is fixedly connected to the feed roller 4. A force sensor 17 is fixedly connected to one end of the metering device 12, and an arc-shaped contact block 15 is inserted into the other end of the metering device 12. The arc-shaped contact block 15 abuts against the equidistant contact rod 11. When the arc-shaped contact block 15 abuts, it will... When the device is pressed backward, a pressure rod 18 is fixedly connected to one end of the arc-shaped contact block 15. The pressure rod 18 contacts the force sensor 17 to complete the sensing and measurement function. The pressure rod 18 and the force sensor 17 are in contact and cooperate. Shock-absorbing springs 16 are fixedly connected to both sides between the force sensor 17 and the pressure rod 18. The shock-absorbing springs 16 provide elastic support and can quickly reset the pressure rod 18 and the arc-shaped contact block 15, thus facilitating continuous measurement. A connecting line 13 is fixedly connected to the rear end of the meter 12.

[0026] Working principle: During operation, the medicine inside the medicine tank 7 is first pumped by the medicine pump 5 through the inlet pipe 6 to the outlet pipe 2, thus treating the wastewater in the wastewater tank 1. Once the medicine reaches the metering pump body 3, it is driven by the drive motor 9, which rotates the feed roller 4. The feed roller 4 has several arc-shaped grooves on its outer side for easy storage of the medicine. After storage, the drive motor 9 rotates the feed roller 4, causing the medicine to fall from above to the bottom of the metering pump body 3 and be discharged through the outlet pipe 2. During the rotation of the feed roller 4, the turntable 10 can be rotated synchronously. During the rotation, the equidistant contact rod 11 will be rotated. At this time, the arc-shaped contact block 15 abuts against the equidistant contact rod 11. After the arc-shaped contact block 15 abuts, it will be squeezed backward. After squeezing, it can abut against the contact force sensor 17 through the contact pressure rod 18, thereby completing the sensing and metering function. After the abutment, the shock-absorbing spring 16 provides elastic support, which can quickly reset the contact pressure rod 18 and the arc-shaped contact block 15, thus facilitating continuous metering. The dosage can be calculated based on the number of rotations of the feed roller 4.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
