Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment chemical dosing and dispensing device. Background Technology

[0002] In wastewater treatment, chemical dosing is necessary during the process. The chemicals typically used are PAC or PAFC, which are prepared and then pumped into the appropriate sedimentation tanks via pumps and pipelines. Since wastewater treatment plants usually have multiple sedimentation tanks, a fixed amount of chemicals needs to be added to each tank based on its volume and wastewater flow rate. Current dosing systems mainly consist of a mixing tank. After the chemicals are added to the mixing tank, they are pumped into the corresponding sedimentation tanks via a main suction pipe and multiple branch pipes. Flow control valves are installed on the branch pipes to regulate the dosage.

[0003] However, the above-mentioned dosing device structure still has the following drawbacks: 1. Generally speaking, the sedimentation tanks are all the same size and the influent flow rate is also the same. Therefore, multiple sedimentation tanks need to have the same dosing amount. The dosing branch pipes are equipped with flow regulating valves, which regulate the flow rate of the corresponding dosing branch pipes. One dosing pump provides power to all dosing branch pipes. Therefore, it is difficult to ensure that the flow rate of all dosing branch pipes is consistent. Especially after long-term use, scale may accumulate in the flow regulating valves, resulting in a smaller dosing amount and affecting the accuracy of dosing; 2. The current dosing method is to prepare the dosing solution in a mixing tank. In order to reduce the power of the dosing pump, the concentration of the reagent in the mixing tank is generally relatively high. This can reduce the dosing flow rate and thus reduce the power of the dosing pump. However, because the reagent concentration is relatively high, any fluctuation in the dosing flow rate will lead to inaccurate dosing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wastewater treatment chemical dosing and distribution device that can ensure the consistency of the chemical dosing amount in each sedimentation tank.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a wastewater treatment chemical dosing and distribution device, including a dilution tank and a distribution tank. The dilution tank is provided with a water inlet for communication with a water injection system and a chemical dosing inlet for communication with a chemical dosing pipeline. The distribution tank includes a distribution tank body, and the distribution tank body is provided with two parallel first partition plates and two parallel second partition plates. The two first partition plates form a main chamber, which is connected to the dilution tank through a connecting pipe. The first partition plates and the corresponding second partition plates form distribution chambers of equal volume. Two equal-sized main dispensing chambers are formed between the dispensing boxes. A third partition plate perpendicular to the second partition plate is also provided on the dispensing box, which divides the main dispensing chamber into equal-sized sub-dispensing chambers. The upper end of the second partition plate is lower than the upper end of the first partition plate. The upper end of the second partition plate is provided with a dispensing notch of the same size and height that connects the dispensing chamber and each sub-dispensing chamber. The first partition plate is provided with a connecting hole of the same size that connects the dispensing chamber and the main chamber. The bottom of the dispensing box is provided with a dispensing pipe that connects to each sub-dispensing chamber.

[0006] As a preferred embodiment, the second partition plate is provided with multiple distribution notches, and the number of distribution notches corresponding to each dispensing chamber is equal.

[0007] As a preferred embodiment, the upper end of the second partition plate is provided with a blocking plate for blocking one or more distribution gaps.

[0008] As a preferred embodiment, the second partition plate is provided with a straight groove or a straight protrusion, and correspondingly, the blocking plate is provided with a straight protrusion or a straight groove that slides in cooperation with the straight groove or straight protrusion.

[0009] As a preferred embodiment, the lower end of the blocking plate is provided with a straight groove for fastening the second partition plate, and the side wall of the straight groove is provided with a straight protrusion or a straight groove.

[0010] As a preferred embodiment, the upper end of the baffle plate is provided with an operating lever.

[0011] As a preferred embodiment, the dilution tank is also equipped with a pipeline mixer, the outlet of which is connected to the dilution tank, and the other two inlets of the pipeline mixer are a water injection port and a chemical dosing port, respectively.

[0012] As a preferred embodiment, the top of the dilution tank is detachably fitted with a top cover that seals the top opening of the dilution tank. The dispensing tank is also provided with two observation ports, which correspond to the positions of the dispensing chamber and the drug dispensing chamber. Each observation port is detachably fitted with a sealing plate to cover the observation port.

[0013] After adopting the above technical solution, the effect of this utility model is as follows: A wastewater treatment dosing and distribution device includes a dilution tank and a distribution tank. The dilution tank is provided with a water inlet for communication with a water injection system and a dosing inlet for communication with a dosing pipeline. The distribution tank includes a distribution tank body, within which are provided two parallel first partition plates and two parallel second partition plates. The two first partition plates form a common chamber, which is connected to the dilution tank via a connecting pipe. The first partition plates and their corresponding second partition plates form distribution chambers of equal volume. The second partition plate and the distribution tank body form two chambers of equal volume. The distribution box has an equal total dispensing chamber. A third partition plate, perpendicular to the second partition plate, divides the total dispensing chamber into equal-sized individual dispensing chambers. The upper end of the second partition plate is lower than the upper end of the first partition plate. The upper end of the second partition plate has a dispensing notch of the same size and height connecting the dispensing chambers and each individual dispensing chamber. The first partition plate has a connecting hole of the same size connecting the dispensing chambers and the total chamber. The bottom of the distribution box has a dispensing pipe connecting each individual dispensing chamber. Therefore, this dispensing device has at least the following advantages compared to existing structures: 1. This dosing and distribution device employs a dilution tank, which dilutes the agent, reducing its concentration and minimizing the impact of flow fluctuations on the dosage. 2. The dilution tank continuously receives medication, causing its level and pressure to rise. This forces the medication through the connecting pipe into the main chamber of the distribution tank, and then through the connecting holes in the main chamber into the two distribution chambers. As the medication level gradually rises and exceeds the second partition plate, the medication flows through the distribution notch on the second partition plate into the dispensing chamber. Because the liquid levels in the distribution chambers are consistent,… The amount of medicine flowing out from the distribution gap on the second partition plate is also consistent. The flowing medicine will flow into the sedimentation tank through the distribution pipe at the bottom of the distribution chamber to complete the dosing. Since all the distribution gaps are the same size and height, the amount of medicine flowing into each distribution chamber is also the same. This ensures that the amount of medicine flowing into each sedimentation tank is also the same, thus ensuring the stability and consistency of the dosing. 3. By controlling the amount of medicine added in the dilution tank, the amount of medicine flowing into the main chamber can be controlled. This will change the height of the liquid level in the distribution chamber, and the amount flowing out from the distribution gap can be controlled, thereby achieving the adjustment of the dosing.

[0014] Since the upper end of the second partition plate is provided with a blocking plate for blocking one or more dispensing gaps, one or more dispensing gaps can be blocked by the blocking plate, thereby further controlling the number of dispensing gaps used and thus accurately controlling the amount of medicine added.

[0015] Because the lower end of the baffle plate is provided with a straight fastening groove that covers the second partition plate, and the side wall of the straight fastening groove is provided with a straight protrusion or a straight groove, the installation of the baffle plate is more convenient. The upper end of the baffle plate is provided with an operating lever, which allows for easy operation and movement of the baffle plate.

[0016] Since the dilution tank is also equipped with a pipeline mixer, the outlet of the pipeline mixer is connected to the dilution tank, and the other two inlets of the pipeline mixer are the water injection port and the chemical addition port, the pipeline mixer is a conventional structure. The pipeline mixer can further ensure that the chemical and dilution water are fully mixed and improve the uniformity.

[0017] The dilution tank has a detachable top cover that seals the top opening. The dispensing tank also has two observation ports that correspond to the positions of the dispensing chamber and the dispensing chamber. Each observation port is detachably fitted with a sealing plate that covers the observation port. The removal of the sealing plate and the top cover allows for convenient internal inspection and observation. Attached Figure Description

[0024] The present invention will be further described in detail below through specific embodiments.

[0025] like Figure 1-4As shown, a wastewater treatment chemical dosing and distribution device includes a dilution tank 1 and a distribution tank 2. The dilution tank 1 is provided with a water inlet 3 for communication with a water injection system and a chemical dosing inlet 9 for communication with a chemical dosing pipeline. The distribution tank 2 includes a distribution tank body 21. The distribution tank body 21 is provided with two parallel first partition plates 4 and two parallel second partition plates 5. The two first partition plates 4 form a common chamber 6, which is connected to the dilution tank 1 through a connecting pipe 7. The first partition plates 4 and the corresponding second partition plates 5 form distribution chambers 8 of equal volume. Two distribution chambers 8 are formed between the second partition plates 5 and the distribution tank body 21. The total dispensing chamber has an equal volume. The dispensing box 21 is also provided with a third partition plate 10 perpendicular to the second partition plate 5. The third partition plate 10 divides the total dispensing chamber into dispensing chambers 11 of equal volume. The upper end of the second partition plate 5 is lower than the upper end of the first partition plate 4. The upper end of the second partition plate 5 is provided with a dispensing notch 13 of the same size and height that connects the dispensing chamber 8 and each dispensing chamber 11. The first partition plate 4 is provided with a connecting hole of the same size that connects the dispensing chamber 8 and the total chamber 6. The bottom of the dispensing box 2 is provided with a dispensing pipe 12 that connects to each dispensing chamber 11.

[0026] In this embodiment, each second partition plate 5 is provided with multiple distribution notches 13, and the number of distribution notches 13 corresponding to each dispensing chamber 11 is equal. A blocking plate 14 is provided at the upper end of the second partition plate 5 to block one or more distribution notches 13. The second partition plate 5 is provided with linear grooves 15 or linear protrusions, and correspondingly, the blocking plate 14 is provided with linear protrusions or linear grooves 15 that slide in cooperation with the linear grooves 15 or linear protrusions. A linear fastening groove is provided at the lower end of the blocking plate 14 to cover the second partition plate 5, and the linear protrusions or linear grooves 15 are provided on the sidewall of the linear fastening groove. An operating rod 16 is provided at the upper end of the blocking plate 14.

[0027] The dilution tank 1 is also equipped with a pipe mixer 17, the outlet of which is connected to the dilution tank 1. The other two inlets of the pipe mixer 17 are a water inlet 3 and a chemical dosing inlet 9. A top cover 18 is detachably installed on the top of the dilution tank 1, which seals the top opening of the dilution tank 1. The distribution tank 2 is also equipped with two observation ports, which correspond to the positions of the distribution chamber 8 and the chemical dispensing chamber 11. A sealing plate 19 is detachably installed on the observation ports to cover them. The bottom of the distribution tank 21 is also equipped with multiple drain pipes 20 that are respectively connected to the main chamber 6 and the distribution chamber 8. The drain pipes 20 are used to drain the liquid in the main chamber 6 and the distribution chamber 8.

[0028] This invention utilizes a dilution tank 1, which dilutes the medication, reducing its concentration and minimizing the impact of flow fluctuations on dosage. Medication continuously enters the dilution tank 1, causing its level and pressure to rise. The medication is then forced through the connecting pipe 7 into the main chamber 6 of the distribution tank 2, and then through the connecting holes in the main chamber 6 into the two distribution chambers 8. As the medication level gradually rises, when it exceeds the second partition plate 5, the medication flows through the distribution notch 13 on the second partition plate 5 into the dispensing chamber 11. Since the two distribution chambers 8... With consistent liquid levels, the amount of medicine flowing out from the distribution gaps 13 on the second partition plate 5 is also consistent. The flowing medicine will flow into the sedimentation tank through the distribution pipe 12 at the bottom of the distribution chamber 11 to complete the dosing. Since all the distribution gaps 13 have the same size and height, the baffle plate 14 can control the number of distribution gaps 13 used, thus accurately controlling the dosing amount. An operating rod 16 is provided at the upper end of the baffle plate 14, which can easily operate and move the position of the baffle plate 14 to adjust the dosing amount. The amount of medicine flowing into each distribution chamber 11 is also the same, ensuring the stability and consistency of the dosing amount.

[0029] Furthermore, the pipeline mixer 17 can further ensure thorough mixing of the agent and dilution water. Two observation ports are also provided on the dispensing tank 2, allowing for real-time observation of the dispensing chamber 8 and the dispensing chamber 11, further guaranteeing the stability of the dosage.

[0030] Of course, a grid can also be installed inside the dilution tank 1 so that the reagent and dilution water can be further mixed after entering the dilution tank 1, thereby improving uniformity.

[0031] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
