Description

Technical Field

[0001] This invention relates to a pharmaceutical storage container, and more particularly to a PAC pharmaceutical tank with a residue-pharmaceutical separation system and its operating method. Background Technology

[0002] PAC liquid reagent is a commonly used agent in water purification plants. It is used to remove suspended solids and colloids such as silt, algae, and humic acid from raw water, reducing turbidity and decreasing the amount of subsequent disinfectants needed, while also inhibiting the formation of disinfection byproducts. PAC reagent tanks contain PAC liquid reagent. When PAC liquid reagent is transported from the manufacturer to the user's storage tank / reactor, it is not clumped. However, over time, PAC reagent may clump, resulting in a large amount of residue inside the tank. The residue mainly floats on the surface of the reagent, and some residue may also settle at the bottom of the tank. Figure 1 As shown.

[0003] Since the medicine tank has only one outlet, the residue from the medicine will also flow out when the medicine is discharged, causing the outlet pipe to be frequently blocked. It needs to be cleaned twice a week, which consumes a lot of manpower, resources and time. If a filter is installed at the inlet of the outlet pipe, the dispensing speed will be greatly reduced, and the filter head will need to be replaced frequently. This will seriously affect normal production and water quality compliance.

[0004] Regarding the improvement of caking and sludge removal, the water purification plant implemented the following solutions: 1. Installing a stirrer inside the tank to prevent PAC (polyacrylamide) from caking; 2. Having workers stand on top of the tank and use a net to scoop out sludge from the filling port, but this solution was difficult to operate, labor-intensive, and inefficient; 3. Having workers enter the tank regularly to clean the sediment, but this solution required three people working simultaneously and took two days. All three solutions were rejected due to their poor effectiveness, high workload, and long processing time.

[0005] Currently, the medicine tank has only one outlet, and can only have one outlet. Adding another outlet would increase the risk of leakage, so solving the problem of frequent blockages in the medicine tubing is an urgent issue we need to address. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a PAC agent tank with a residue-drug separation system and its working method. It can store PAC agents for a long time without maintenance, and at the same time, it can quickly remove the residue when maintenance is required. It has high maintenance efficiency and saves a lot of manpower and material resources.

[0007] The technical solution adopted in this invention is as follows: A PAC reagent tank with a residue-removal system includes a tank body and a discharge pipe. The inlet of the discharge pipe is connected to the interior of the tank body. A reagent pump is installed on the discharge pipe. The residue-removal system is installed inside the tank body. The residue-removal system includes a first straight pipe, a second straight pipe, a third straight pipe, and a fourth straight pipe. The first straight pipe is located at the bottom of the tank body and is horizontally arranged. A plug is installed at the inlet of the first straight pipe, and the outlet of the first straight pipe is connected to the inlet of the discharge pipe. The second straight pipe is vertically arranged, and its outlet is connected to the middle of the first straight pipe. The inlet of the second straight pipe is connected to the outlet of the third straight pipe, and the inlet of the third straight pipe is connected to the outlet of the fourth straight pipe. The fourth straight pipe is vertically arranged, with its inlet facing downwards. The inlet of the fourth straight pipe is located higher than the inlet of the first straight pipe.

[0008] Furthermore, a filter head is provided at the inlet of the fourth straight pipe, and the inlet of the fourth straight pipe is connected to the top of the filter head; the top surface of the filter head does not have filter holes, and the side of the filter head is provided with two rows of filter grooves, the length direction of the filter groove is located in the vertical direction, and the width of the filter groove is 1mm-2mm.

[0009] Furthermore, the diameter of the fourth straight pipe is the same as that of the third straight pipe, and the diameter of the third straight pipe is larger than that of the second straight pipe.

[0010] Furthermore, the inlet of the third straight pipe is lower than the outlet of the third straight pipe.

[0011] Furthermore, the bottom of the filter head is 15-25cm away from the bottom of the barrel inside the barrel.

[0012] Furthermore, a flared opening is provided at the inlet of the first straight pipe.

[0013] Furthermore, the plug is an internal hexagonal threaded plug, with the groove of the internal hexagonal threaded plug facing the outlet of the first straight pipe; after the internal hexagonal screwdriver is inserted from the outlet of the first straight pipe, it is adapted to the internal hexagonal groove of the internal hexagonal threaded plug, thereby installing the internal hexagonal threaded plug at the inlet of the first straight pipe or removing it from the inlet of the first straight pipe.

[0014] The operating method of the PAC reagent tank with the residue-removal system is as follows: ① When there is residue on both the surface and bottom of the PAC agent in the tank, the plug blocks the inlet of the first straight pipe, and the PAC agent in the middle layer enters from the inlet of the fourth straight pipe and flows out from the outlet of the straight pipe. ② When the liquid level of PAC agent in the tank decreases, the drug residue floating on the liquid surface approaches the filter head. Since the top surface of the filter head does not have filter holes, it effectively prevents the drug residue from falling from the filter holes on the top surface of the filter head into the straight pipe of the drug outlet and causing blockage. ③ When the liquid level of PAC agent in the tank continues to decrease, once air begins to enter the top of the upper filter tank on the side of the filter head, the pump will stop working, and the drug residue will not be able to enter the straight pipe of the drug outlet. ④ When the amount of medicine residue settled at the bottom of the barrel reaches a certain level, the medicine residue at the bottom of the barrel can be cleaned. At this time, insert an Allen screwdriver into the outlet of the first straight pipe and match it with the Allen groove of the plug. Then remove the plug from the inlet of the first straight pipe. After the plug is removed, the medicine residue at the bottom of the barrel can be rinsed with a water gun from the medicine filling port, so that the medicine residue flows out from the first straight pipe and is discharged through the medicine outlet straight pipe.

Detailed Implementation

[0016] like Figure 3As shown in this embodiment, a PAC reagent tank with a residue-removal system includes a tank body 1 and a discharge pipe 2. The inlet of the discharge pipe 2 is connected to the interior of the tank body 1. A reagent pump M is installed on the discharge pipe 2. The residue-removal system is installed inside the tank body 1. The residue-removal system includes a first straight pipe 3, a second straight pipe 4, a third straight pipe 5, and a fourth straight pipe 6. The first straight pipe 3 is located at the bottom of the tank body 1 and is horizontally arranged. A plug 7 is installed at the inlet of the first straight pipe 3, and the outlet of the first straight pipe 3 is connected to the inlet of the discharge pipe 2. The second straight pipe 4 is vertically arranged, and the outlet of the second straight pipe 4 is connected to the middle of the first straight pipe 3. The inlet of the second straight pipe 4 is connected to the outlet of the third straight pipe 5, and the inlet of the third straight pipe 5 is connected to the outlet of the fourth straight pipe 6. The fourth straight pipe 6 is vertically arranged, and the inlet of the fourth straight pipe 6 faces downward. The inlet of the fourth straight pipe 6 is located higher than the inlet of the first straight pipe 3. In this embodiment, the design achieves residue-powder separation through a specific multi-stage pipeline layout. The fourth straight pipeline inlet faces downwards and is positioned higher than the first straight pipeline inlet. Utilizing gravity, denser impurities settle at the bottom of the tank, while the relatively pure reagent enters the outlet straight pipe through each stage of pipelines. This effectively reduces the impurity content in the reagent and improves its purity. The reagent separation system prevents impurities from directly entering the outlet straight pipe and the pump. Impurities are intercepted in specific pipeline areas or settle at the bottom of the tank, reducing the risk of pipeline and pump blockage due to impurities, ensuring smooth reagent delivery, and reducing equipment failure and maintenance frequency.

[0017] In this embodiment, the slag-powder separation system significantly reduces the wear and blockage of pipelines and pumps caused by impurities, thereby reducing equipment maintenance workload and costs. Frequent pipeline cleaning and pump repairs are unnecessary, saving manpower and material resources. Reduced damage to equipment from impurities helps extend the service life of the entire reagent tank system and related equipment. In the long term, it reduces the frequency of equipment replacement, saving companies equipment procurement costs. This design is structurally clear, with well-defined pipeline connections at each level, allowing operators to easily understand and master its working principles and operating methods. In daily use and maintenance, no complex professional knowledge or skills are required, reducing operational difficulty. This reagent tank design is suitable for PAC reagents of different qualities and impurity contents. Regardless of the initial state of the reagent, the slag-powder separation system can function to a certain extent, ensuring the normal delivery and use of the reagent, demonstrating strong adaptability and versatility.

[0018] In this embodiment, a filter head 8 is provided at the inlet of the fourth straight pipe 6, and the inlet of the fourth straight pipe 6 is connected to the top of the filter head 8. The top surface of the filter head 8 has no filter holes, and the side of the filter head 8 has two rows of filter grooves 9, one above the other. The length direction of the filter grooves 9 is vertical, and the width of the filter grooves 9 is 1mm. The two rows of vertically oriented filter grooves on the side of the filter head, with a width of only 1mm, allow for strict screening of the reagent entering the fourth straight pipe. Compared to ordinary filtration devices, it can more effectively intercept impurities with a particle size greater than 1mm in the reagent, such as solid particles and precipitates, greatly improving the purity of the reagent and ensuring the quality of the reagent entering subsequent pipes and systems. The vertically oriented filter grooves facilitate the natural settling of impurities under gravity, reducing the adhesion and clogging of impurities on the surface of the filter head, ensuring the continuous effectiveness of the filtration function, and allowing the reagent to smoothly pass through the filter head into the fourth straight pipe. The purified reagent after filtration enters the outlet straight pipe and is then extracted by the pump. Pure pharmaceutical agents reduce the risk of wear and blockage inside the pump, enabling it to operate under stable conditions. This avoids problems such as decreased pump performance, increased vibration, and increased noise caused by excessive impurities in the pharmaceutical agent, thus ensuring the pump's service life and working efficiency.

[0019] In this embodiment, the diameter of the fourth straight pipe 6 is the same as that of the third straight pipe 5, and the diameter of the third straight pipe 5 is larger than that of the second straight pipe 4. Because the third straight pipe has a larger diameter than the second straight pipe, when the reagent flows from the third straight pipe into the second straight pipe, the flow velocity increases accordingly due to the smaller pipe diameter, according to fluid mechanics principles. This change in flow velocity helps to enhance the turbulence of the reagent within the second straight pipe, allowing impurities in the reagent to be better separated from the pure reagent, thus improving the separation effect of slag and reagent. The larger diameters of the third and fourth straight pipes provide a relatively spacious flow space for the reagent, allowing sufficient time and space for impurities to settle during the flow process. Impurities gradually sink under gravity, while the pure reagent continues to flow upwards into subsequent pipes, thereby improving the separation efficiency of impurities and reducing the impurity content entering the discharging system. The larger diameters of the third and fourth straight pipes can accommodate more impurities, reducing the possibility of pipe blockage due to impurity accumulation. Even if the reagent contains a certain amount of impurities, there is sufficient space for the impurities to pass through, avoiding problems such as increased pipeline pressure and equipment damage caused by blockage, thus ensuring the stable operation of the entire slag-reagent separation system. Stable fluid flow and efficient slag-reagent separation ensure a continuous supply and high-quality output of the reagent, improving the efficiency of the entire production process. It reduces production interruptions and product defects caused by reagent quality issues, bringing higher economic benefits to the enterprise.

[0020] In this embodiment, the inlet of the third straight pipe 5 is lower than its outlet. Based on the principle of gravity, denser impurities will naturally sink in the reagent. The design of the third straight pipe having an inlet lower than its outlet creates an upward inclined path for the reagent to flow within the pipe. As impurities flow upward with the reagent, they are more likely to settle to the lower bottom of the pipe due to gravity, rather than flowing out of the pipe with the reagent, thus improving the efficiency of slag-powder separation and making the reagent entering the subsequent system purer. This inclined design helps impurities accumulate at the bottom of the pipe. Operators can install drain outlets or other devices at the lower bottom of the pipe to periodically discharge the accumulated impurities, preventing them from accumulating in the pipe for a long time and affecting the separation effect. At the same time, the relatively pure reagent flows out from the higher outlet, further ensuring the quality of the reagent. The design of the inlet being lower than the outlet utilizes gravitational potential energy, allowing the reagent to flow naturally to a certain extent by its own weight. This reduces dependence on external power equipment (such as pumps) and lowers energy consumption. When large quantities of reagent are not required or the required conveying speed is not high, the reagent can flow slowly by gravity to meet basic conveying needs. Under the influence of gravity, the flow velocity of the reagent within the inclined pipe is relatively stable. Compared to horizontal pipes, this design avoids the uneven flow velocity problems that can occur with horizontal flow, reduces the formation of turbulence and eddies, and allows for smoother reagent delivery, which is beneficial for the stable operation of subsequent treatment processes. Stable fluid flow and less clogging by impurities reduce wear and impact on the pipes and connected equipment (such as valves and pumps). This helps extend equipment lifespan, reduce equipment replacement frequency, and thus lower equipment procurement costs and overall operating costs.

[0021] In this embodiment, the bottom of the filter head 8 is 20cm above the bottom of the barrel 1. The inlet of the filter head 8 is suspended, ensuring that the 20cm height between the filter head 8 and the bottom of the barrel prevents sludge from being sucked into the discharge tube, allowing it to settle at the bottom. Simultaneously, the 20cm height provides sufficient operating space for cleaning the sediment at the bottom of the barrel, allowing operators to easily remove the deposited impurities without interference from the filter head. This improves the efficiency and safety of the cleaning process.

[0022] In this embodiment, a flared end 10 is provided at the inlet of the first straight pipe 3. The flared end 10 facilitates better entry of the dregs into the first straight pipe 3 during cleaning, effectively increasing the speed of dreg removal.

[0023] In this embodiment, the plug 7 is an internal hexagonal threaded plug, with the groove of the internal hexagonal threaded plug facing the outlet of the first straight pipe 3; after the internal hexagonal screwdriver is inserted from the outlet of the first straight pipe 3, it is adapted to the internal hexagonal groove of the internal hexagonal threaded plug, thereby installing the internal hexagonal threaded plug at the inlet of the first straight pipe 3 or removing it from the inlet of the first straight pipe 3.

[0024] In this embodiment, the working method of the PAC reagent tank with the residue-removal system is as follows: ①For example Figure 4 As shown, when there is residue on both the surface and bottom of the PAC agent in the tank 1, the plug 7 blocks the inlet of the first straight pipe 3, and the PAC agent in the middle layer enters from the inlet of the fourth straight pipe 6 and flows out from the outlet of the straight pipe 2. ② When the liquid level of PAC agent in the tank 1 decreases, when the drug residue floating on the liquid surface approaches the filter head, since the top surface of the filter head 8 does not have filter holes, it effectively prevents the drug residue from falling from the filter holes on the top surface of the filter head 8 into the drug outlet straight pipe 2 and causing blockage. ③ When Figure 5 As shown, when the liquid level of PAC agent in the tank 1 continues to decrease, once air begins to enter the top of the upper filter tank 9 on the side of the filter head 8, the drug pump M will stop working, and the drug residue will not be able to enter the drug outlet straight pipe 2. ④ When Figure 6 As shown, when the amount of medicine residue settled at the bottom of the barrel 1 reaches a certain level, the medicine residue at the bottom of the barrel can be cleaned. At this time, insert an Allen screwdriver into the outlet of the first straight pipe 3 and match it with the Allen groove of the plug 7, and then remove the plug 7 from the inlet of the first straight pipe 3. After the plug 7 is removed, the medicine residue at the bottom of the barrel can be rinsed with a water gun from the medicine filling port, so that the medicine residue flows out from the first straight pipe 3 and is discharged through the medicine outlet straight pipe 2.

[0025] In this embodiment, when a small amount of residue is suspended in the agent, the filter head 8 is a filter head with a diameter of 16cm or more. The large filter head has a throughput much greater than the flow rate of the drug outlet pipe, which effectively prevents the residue from adsorbing on the surface of the filter head and entering the drug outlet pipe. In addition, the groove hole processing technology of the filter head adopts slow wire cutting to prevent the filter groove from deforming during the processing, which would cause the gap of the filter groove to become larger and affect the filtration effect.

[0026] When the sediment at the bottom of the tank reaches a certain amount, it can be cleaned after about 18 months. At this time, unscrew the threaded plug (take it out towards the right-side pipe opening). After removing the plug, use a water gun to flush the sediment at the bottom of the tank through the loading port, allowing the sediment to flow out from the discharge pipe. This sludge-liquid separation system truly achieves the function of having a single discharge pipe that does not discharge sludge when conveying liquid agents and does not convey liquid agents when discharging sludge.

[0027] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
