"Upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0035] First, the variable chemical agent dosage alarm device of the embodiments of the present utility model will be specifically described below in conjunction with the accompanying drawings.

[0036] Figure 1 It is a schematic diagram of the variable chemical agent dosage alarm device according to an embodiment of the present utility model. Figure 2 It is an application schematic diagram of the variable chemical agent dosage alarm device according to an embodiment of the present utility model.

[0037] Specifically, as Figures 1 to 2 shown, the variable chemical agent dosage alarm device according to the embodiments of the present utility model is mainly used for wastewater treatment and may include: a chemical agent storage device 1, a liquid level measuring device 2, and an alarm 3.

[0038] Among them, an accommodation cavity is arranged inside the medicine storage device 1. A liquid discharge pipe 11 is arranged at the lower end of the side surface of the medicine storage device 1. The liquid discharge pipe 11 is communicated with the accommodation cavity, and the liquid discharge pipe 11 is used for discharging the medicine in the accommodation cavity to the wastewater treatment pool 200. An inlet pipe 12 is arranged at the top of the medicine storage device 1. One end of the inlet pipe 12 is communicated with the accommodation cavity, and the other end of the inlet pipe 12 is used for being communicated with the medicine adding device 100. The liquid level measuring device 2 is arranged on the medicine storage device 1, and the liquid level measuring device 2 is used for detecting the liquid level of the medicine in the accommodation cavity. The alarm 3 is connected to the liquid level measuring device 2. When the liquid level measuring device 2 detects that the liquid level of the medicine in the accommodation cavity reaches the high liquid level alarm point or the low liquid level alarm point, the alarm 3 starts to alarm and sends an alarm message to the network communication device at the same time, and the network communication device then sends the alarm message to the wireless mobile terminal 4.

[0039] That is to say, by arranging the liquid level measuring device 2 on the medicine storage device 1 to monitor the liquid level height of the medicine in the accommodation cavity in real time. When the liquid level of the medicine in the accommodation cavity reaches the preset high liquid level alarm point, it means that the medicine is about to overflow or has exceeded the safe storage amount. At this time, the alarm 3 connected to the liquid level measuring device 2 starts to alarm, and at the same time, the alarm 3 sends an alarm message to the network communication device, and the network communication device then sends the alarm message to the wireless mobile terminal 4 of the operator, such as the operator's mobile phone, etc. No matter where the operator is, they can know in time and take measures. Similarly, when the liquid level of the medicine in the accommodation cavity reaches the preset low liquid level alarm point, it means that the medicine stock is insufficient and needs to be replenished. At this time, the alarm 3 connected to the liquid level device also starts to alarm, and at the same time, the alarm 3 sends an alarm message to the network communication device, and the network communication device then sends the alarm message to the wireless mobile terminal 4 of the operator.

[0040] Therefore, the medicine dosage change alarm device provided by the present utility model can avoid the interruption of the medicine flow or the overflow of the excessive added medicine during the medicine adding process of the wastewater treatment, ensure the continuity and stability of the wastewater treatment production process, eliminate the need for continuous manual monitoring, reduce the labor cost and the risk of human negligence. At the same time, the alarm 3 has a rapid response. Once the liquid level of the medicine is abnormal, the alarm mechanism is immediately started, shortening the response time. And through the network communication device, the alarm message can be timely conveyed to the wireless mobile terminal 4 of the operator. No matter where the operator is, they can know in time and take measures.

[0041] In addition, the application scenario of the present utility model is not limited to wastewater treatment. In cases where it is necessary to control the high and low liquid levels and manual real-time monitoring is impossible, the medicine dosage change alarm device provided by the present application can be applied, and it is not limited to adding medicine. As long as it is adding liquid, it is within the protection scope of the present application.

[0042] In some embodiments of the present utility model, refer to Figure 1An overflow pipe 13 is provided at the upper end of the side of the medicine storage device 1. The overflow pipe 13 is connected to the accommodating chamber, and the overflow pipe 13 can also be connected to the wastewater treatment tank 200. That is to say, on the one hand, when the agent is added in excess or the liquid level exceeds the set maximum safety line due to other reasons, the excess agent will be automatically discharged to the wastewater treatment tank 200 through the overflow pipe 13 to prevent the medicine storage device 1 from leaking or being damaged due to excessive agent. On the other hand, an overflow port is provided. When the operator needs to adjust the inlet flow rate and the outlet flow rate of the medicine storage device 1 to achieve a balance, he only needs to adjust and observe the overflow of the overflow pipe 13 to a drip-like state, and then the inflow and outflow of the agent inside the medicine storage device 1 will be balanced.

[0043] In some embodiments of the present invention, reference Figure 1 The liquid level measuring device 2 includes a light column liquid level meter, which includes: a liquid level probe 21 and a processor 22. The liquid level probe 21 is arranged in the receiving chamber, and the liquid level probe 21 is provided with a first alarm contact corresponding to the high liquid level alarm point and a second alarm contact corresponding to the low liquid level alarm point. The processor 22 is connected to the liquid level probe 21 and the alarm 3, and the processor 22 is used to process the detection information of the liquid level probe 21 and send the alarm information to the alarm 3. Specifically, the liquid level probe 21 (also called the liquid level sensor) detects the change of the liquid level in real time, the processor 22 receives and processes the signal transmitted by the liquid level probe 21, and updates the liquid level data in real time. The operator can set or adjust the alarm threshold of the high and low liquid levels through the display control interface of the processor 22 (such as the display 23), so as to realize the flexible configuration of the alarm point. Once the liquid level in the receiving chamber reaches the set alarm point (such as the first alarm contact or the second alarm contact), the processor 22 sends the alarm information to the alarm 3. Therefore, the device can quickly and accurately respond to abnormal liquid levels of the reagent, reduce problems that may be caused by untimely manual inspections, reduce manual inspections, and improve work efficiency. In addition, by early warning of low or high liquid levels, it helps to replenish the reagent in time, prevent reagent shortages or overflow accidents, and ensure the continuity and safety of the wastewater treatment process.

[0044] It should be noted that the first alarm contact (corresponding to the high liquid level alarm point) and the second alarm contact (corresponding to the low liquid level alarm point) are virtual alarm threshold points set by the operator in the control interface of the processor 22, and do not involve the closure of physical contacts, but through the real-time analysis of the liquid level data by the processor 22 to determine whether the liquid level reaches the preset alarm condition. The operator can reset the high liquid level alarm point or the low liquid level alarm point, that is, the first alarm contact or the second alarm contact, according to the actual dosing situation.

[0045] In some embodiments of the present invention, reference Figure 1, the light column liquid level gauge further includes: a display 23 for displaying the liquid level of the medicament in the accommodation chamber detected by the light column liquid level gauge. After the processor 22 of the light column liquid level gauge receives the electrical signal, it analyzes the signal and calculates the current liquid level height. Then, the processor 22 sends this information to the display 23. The display 23 displays the liquid level in the form of a light column according to the received information. For example, usually, red indicates that the medicament is higher than the high liquid level alarm point or lower than the low liquid level alarm point, and green indicates that the medicament is within the safety threshold between the high and low liquid level alarm points. The height of the light column directly reflects the actual liquid level in the accommodation chamber. Thus, by setting the display 23, the display 23 is updated in real time to reflect the change of the liquid level of the medicament in the accommodation chamber through the change of the light column length. The operator can directly judge the liquid level state from the height and color of the light column, which is simple and fast.

[0046] In some embodiments of the present invention, referring to Figure 1 , the first alarm contact is higher than the overflow pipe 13, and the second alarm contact is higher than the drain pipe 11. Specifically, the first alarm contact is higher than the overflow pipe 13 and lower than the top surface of the medicine storage device 1 to prevent the medicament from overflowing from the top surface of the medicine storage device 1 or flowing back to the inlet pipe 12 due to excessive filling; the second alarm contact needs to be higher than the drain pipe 11, and the position of the second alarm contact can be set according to the actual outflow of the on-site drain pipe 11 combined with the actual inflow of the inlet pipe 12. Thus, a buffer time for the operator to adjust the medicine addition can be provided, the medicament can be replenished in time, and the interruption of the medicament flow during the treatment process can be prevented.

[0047] In some embodiments of the present invention, referring to Figure 1 , the alarm 3 includes an audible and visual alarm. When the liquid level in the accommodation chamber reaches the preset high liquid level alarm point or low liquid level alarm point, the processor 22 activates the audible and visual alarm 3 to emit an alarm sound and is accompanied by a flashing light. Thus, with the simultaneous action of sound and light, the attention of the on-site personnel can be immediately attracted, the emergency information can be transmitted in the first time, the safety of the wastewater treatment is enhanced, and the continuous progress of the production operation process is ensured.

[0048] In some embodiments of the present invention, referring to Figure 1 , a first regulating valve 14 is provided on the inlet pipe 12. Thus, the operator can adjust the inflow of the medicament in the inlet pipe 12 through the first regulating valve 14 to ensure the stable supply of the medicament during the wastewater treatment process. At the same time, in case of an abnormality, such as excessive inflow, the inflow amount can be closed or reduced to play a safety protection role.

[0049] In some embodiments of the present invention, referring to Figure 1, a second regulating valve 15 is provided on the liquid discharge pipe 11. Thus, through the coordinated action of the second regulating valve 15 on the liquid discharge pipe 11 and the first regulating valve 14 on the liquid inlet pipe 12, accurate control of the inflow and outflow of the medicament into the medicament storage device 1 can be achieved, which helps to maintain the stability of the liquid level inside the medicament storage device 1, thereby effectively ensuring the stability and working efficiency during the wastewater treatment process.

[0050] In some embodiments of the present invention, referring to Figure 1 , the wireless mobile terminal 4 includes a mobile phone. Exemplarily, the mobile phone applet of the operator is connected to the alarm 3 through a network communication device to view real-time alarm notifications. Thus, the limitation that the operator needs to be on-site in the traditional alarm method is simplified, the processing efficiency of emergency situations is improved, and the safety guarantee is enhanced.

[0051] In some embodiments of the present invention, referring to Figure 1 , the medicament storage device 1 is a medicament storage barrel with an open top, and the medicament storage barrel is made of wear-resistant and corrosion-resistant materials. Thus, the medicament storage device 1 is set as a medicament storage barrel with an open top, which is more convenient for the operator to directly observe the state of the medicament, and is convenient for directly adding supplementary drugs such as flocculants or adsorbents in specific situations. At the same time, the medicament storage barrel is made of wear-resistant and corrosion-resistant materials, has a long service life, reduces the frequent replacement caused by container damage, and can reduce the long-term operation and maintenance costs.

[0052] Based on the above embodiments of the present invention, without explicit negation or conflict, the technical features of one embodiment can be beneficially combined with one or more other embodiments.

[0053] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
