Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a dosing meter for wastewater treatment. Background Technology
[0002] In the wastewater treatment process, the use of dosing instruments is a core element in ensuring stable treatment results, controllable costs, and safe system operation. Dosing instruments can control the amount of chemicals added, thereby ensuring more stable wastewater treatment, reducing deviations caused by excessive or insufficient addition of chemicals, and increasing the efficiency of wastewater treatment. However, traditional dosing instruments are not convenient for evenly spraying chemicals into the wastewater. They require repeated stirring and mixing to ensure sufficient contact between the wastewater and the chemicals, resulting in low efficiency.
[0003] To overcome the aforementioned shortcomings, existing technology (Chinese Patent No. CN220125996U, Publication Date: 2023-12-05) provides a wastewater treatment dosing device, including a dilution tank. A dosing device is located at the top of the dilution tank, and a dosing pump is located on one side of the tank. The dosing pump has an input pipe extending into the interior of the dilution tank, and an output pipe at its output. A water injection pipe is located at the top of the dilution tank, with a water valve on its surface. This wastewater treatment dosing device can be installed next to the wastewater treatment equipment. The dosing device is installed at the top, and the operator only needs to add the reagent through the dosing device. The rest is handled by the main controller. The main controller commands the valve controller, which opens the dispensing valve, allowing the reagent to enter the dilution tank through the dispensing pipe. Then, the water valve opens, and water is injected into the dilution tank through the water injection pipe, mixing the clean water with the reagent. The mixture is then thoroughly mixed by a stirrer, and finally, the diluted reagent is injected into the wastewater treatment equipment via the dosing pump. The entire dosing process requires minimal manual intervention.
[0004] The aforementioned institutions add the chemicals through a feed pipe and then directly inject them into the wastewater treatment equipment. However, directly adding the chemicals into the wastewater requires a mixing device to fully mix the chemicals with the wastewater in order for them to work, resulting in low overall work efficiency. Utility Model Content
[0005] The purpose of this utility model is to provide a dosing meter for wastewater treatment, so as to solve the problem mentioned in the background art that traditional dosing meters are not convenient to spray the agent evenly into the wastewater during use, and require repeated stirring and mixing by a stirring mechanism to ensure full contact between the wastewater and the agent, resulting in low working efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dosing meter for wastewater treatment, comprising a metering device body, two inlets at the top of the metering device body, an outlet at the bottom of the metering device body, and a liquid level detection sensor at the upper inner side of the metering device body; a diversion mechanism for dispersing the agent is provided at the bottom of the metering device body, the diversion mechanism including nozzles, the nozzles being located at the bottom of the outlet, and the outlets being evenly distributed at the bottom of the metering device body; a connecting pipe is internally engaged with the inlets, and a docking mechanism for reducing leakage is provided on the outer side of the inlets.
[0007] Furthermore, a guide plate is provided at the bottom of the metering device body, and a drive motor is fixedly connected at the middle position of the bottom of the guide plate. The output end of the drive motor extends into the interior of the metering device body and is equipped with a support rod, and a rotating plate is fixedly connected to the bottom of the support rod.
[0008] Furthermore, the bottom end of the rotating plate is provided with a matching interface at an equal angle, and the matching interface corresponds to the medicine outlet. The diameter of the matching interface is equal to the diameter of the medicine outlet.
[0009] Furthermore, a rotating rod is installed at the top of the support rod, and a stirring rod is fixedly installed on the outside of the rotating rod.
[0010] Furthermore, the docking mechanism includes a fixed sleeve rod, and a first airbag is attached to the top of the fixed sleeve rod, and a compression plate is attached to the bottom of the first airbag. A second airbag is attached to the bottom of the compression plate, and the second airbag is sleeved on the upper end of the outside of the drug inlet. The first airbag and the second airbag are connected by a flexible tube.
[0011] Furthermore, connecting plates are respectively installed on the outer sides of the connecting pipe and the drug inlet, and the connecting plates are respectively located at the top and bottom of the fixing sleeve rod, and bolts are threadedly connected to the outer sides of the connecting plates.
[0012] Furthermore, the cross-section of the second airbag is inverted "C" shape, and the inner side of the second airbag fits against the upper end of the outer side of the drug inlet.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By providing outlets and nozzles, the chemicals can be diverted from different outlets and nozzles, thereby increasing the contact area between wastewater and chemicals and shortening the mixing time required. Furthermore, the liquid level sensor inside the metering device detects and measures the dosage during chemical addition, preventing over-addition that would necessitate secondary treatment. Dosage monitoring also allows for timely replenishment when chemicals are insufficient, effectively preventing incomplete wastewater treatment and increasing overall applicability.
[0015] Furthermore, a guide plate is provided at the lower end of the metering device body. The guide plate can assist in guiding the flow of the reagent and reduce the residue of the reagent inside the metering device body, so as to effectively reduce the error of reagent addition when adding the reagent.
[0016] Furthermore, the output of the drive motor can drive the support rod to rotate. When the support rod rotates, it will synchronously drive the rotating plate to rotate. The interface on the top of the rotating plate corresponds to the outlet of the medicine. Therefore, the addition and stopping of the medicine can be controlled when the rotating plate rotates, so that the medicine can be added in batches and evenly. After the medicine is added in batches, it works together with the sewage treatment equipment to make the medicine more fully mixed with the sewage, so as to achieve stable sewage treatment.
[0017] 2. The output of the drive motor can drive the support rod to rotate. When the support rod rotates, the rotating rod at the top rotates synchronously. The stirring rod set on the outside of the rotating rod can mix the medicine, reduce the situation of incomplete mixing between the medicine and water, and increase the applicability of the whole when used.
[0018] Furthermore, medicine and water can be added separately through the inlet. To avoid leakage caused by insufficient pipe connection, the connecting pipe is placed inside the inlet, and the second airbag is placed outside the inlet. The bottom of the second airbag is in contact with the extrusion plate. Using gravity, the bottom of the first airbag is kept in a compressed state with the extrusion plate. The gas inside the first airbag is delivered to the inside of the second airbag through the hose, so that the gas inside the second airbag fills the gap between the connecting pipe and the inlet, reducing the appearance of gaps and effectively preventing leakage.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1: As Figure 1 , Figure 2 , Figure 5 and Figure 6The technical solution shown addresses the problem of traditional dosing meters being inconvenient to evenly spray chemicals into wastewater, requiring repeated stirring to ensure sufficient contact between wastewater and chemicals, resulting in low efficiency. This wastewater treatment dosing meter discloses a diversion mechanism, including a metering device body 1. The top of the metering device body 1 has two inlets 2, and the bottom of the metering device body 1 has an outlet 3. A liquid level sensor 12 is installed on the upper inner side of the metering device body 1. The bottom inner side of the metering device body 1 is equipped with a device for diverting the chemicals. The dispersing mechanism for the dispersion treatment includes a nozzle 4, which is located at the bottom of the outlet 3. The outlets 3 are distributed at equal angles at the bottom of the metering device body 1. A guide plate 5 is provided at the bottom of the metering device body 1, and a drive motor 6 is fixedly connected at the middle position of the bottom of the guide plate 5. The output end of the drive motor 6 extends into the interior of the metering device body 1 and is equipped with a support rod 7. A rotating plate 8 is fixedly connected to the bottom of the support rod 7. An interface 9 is opened at equal angles at the bottom of the rotating plate 8, and the interface 9 corresponds to the outlet 3. The diameter of the interface 9 is equal to the diameter of the outlet 3.
[0028] In this example, the metering instrument is located at the chemical addition point of the wastewater treatment equipment. The required chemical is added into the metering instrument body 1 through two inlets 2, and the chemical is mixed by an auxiliary stirring mechanism. Figure 2 and Figure 5 As shown, traditional dosing instruments typically add chemicals directly through a separate pipe. This single-pipe dosing method allows the chemical to be sprayed at only one location, requiring a separate mixing mechanism to agitate the chemical and wastewater. This results in a prolonged mixing time and reduced efficiency. Therefore, by incorporating an outlet 3 and a nozzle 4, the chemical can be diverted from different outlets and nozzles, increasing the contact area between the wastewater and the chemical and shortening the mixing time. Furthermore, the liquid level sensor 12 inside the metering device 1 detects and measures the dosage, preventing overdosing and the need for secondary treatment. Dosage monitoring also allows for timely replenishment when the dosage is insufficient, effectively preventing incomplete wastewater treatment and increasing overall applicability. Figure 2 As shown, a guide plate 5 is provided at the lower end of the metering device body 1. The guide plate 5 assists in guiding the flow of the reagent and reduces reagent residue inside the metering device body 1, thus effectively reducing errors during reagent addition. Figure 5 and Figure 6As shown, the output of the drive motor 6 can drive the support rod 7 to rotate. When the support rod 7 rotates, it will synchronously drive the rotating plate 8 to rotate. The interface 9 opened at the top of the rotating plate 8 corresponds to the medicine outlet 3. Therefore, the rotation of the rotating plate 8 can control the addition and stopping of the agent, so that the agent can be added in batches and evenly. After the agent is added in batches, it works together with the sewage treatment equipment to make the agent more fully mixed with the sewage, so as to achieve stable sewage treatment.
[0029] Example 2: Figure 1 , Figure 2 , Figure 5 and Figure 6 The technical solution shown addresses the problem that incomplete mixing of the reagent and water during reagent addition may lead to deviations in reagent concentration. The wastewater treatment dosing meter discloses an auxiliary stirring mechanism, with a rotating rod 10 mounted on the top of the support rod 7, and a stirring rod 11 fixedly mounted on the outside of the rotating rod 10.
[0030] In this example, the output of the drive motor 6 can drive the support rod 7 to rotate. When the support rod 7 rotates, the rotating rod 10 at the top rotates synchronously. The stirring rod 11 set on the outside of the rotating rod 10 can achieve the mixing of the medicine, reduce the situation of incomplete mixing between the medicine and water, and increase the applicability of the whole when in use.
[0031] Example 3: Figure 1-4 The technical solution shown addresses the problem of leakage due to weak sealing performance of pipeline connections during chemical addition. The wastewater treatment dosing meter discloses a connection mechanism: a connecting pipe 13 is internally engaged with the inlet 2, and a connection mechanism to reduce leakage is provided on the outer side of the inlet 2. The connection mechanism includes a fixing sleeve 14, with a first airbag 15 attached to the top of the fixing sleeve 14, and a compression plate 16 attached to the bottom of the first airbag 15. The first airbag 15 and the second airbag 17 are fitted together and are sleeved on the upper end of the outside of the drug inlet 2. The first airbag 15 and the second airbag 17 are connected by a hose. Connecting plates 18 are respectively installed on the outside of the connecting pipe 13 and the drug inlet 2. The connecting plates 18 are respectively set at the top and bottom of the fixing sleeve 14. Bolts 19 are threaded on the outside of the connecting plates 18. The cross-section of the second airbag 17 is inverted "C" shape, and the inner side of the second airbag 17 is fitted with the upper end of the outside of the drug inlet 2.
[0032] In this example, such as Figure 4As shown, when the agent is mixed with water, the agent and water can be added separately through the inlet 2. To avoid leakage caused by insufficient pipe connection, the connecting pipe 13 is placed inside the inlet 2, and the second airbag 17 is sleeved on the outside of the inlet 2. The bottom end of the second airbag 17 is in contact with the extrusion plate 16. Using gravity, the bottom end of the first airbag 15 is kept in a compressed state with the extrusion plate 16. The gas inside the first airbag 15 is delivered to the inside of the second airbag 17 through the hose, so that the gas inside the second airbag 17 fills the gap between the connecting pipe 13 and the inlet 2, reducing the appearance of gaps and thus effectively preventing leakage. Then, through the cooperation of the connecting plate 18 and the bolt 19, the bolt 19 can lock the two connecting plates 18, increasing the overall stability during use.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
