An autonomous descaling mechanism inside a water storage tank

Abstract

This utility model discloses an autonomous descaling mechanism inside a water storage tank, comprising: a water storage tank body, an inlet valve, and an outlet valve. This utility model relates to the technical field of pharmaceutical water storage equipment. This mechanism achieves a convenient and rapid descaling process through the coordinated operation of a magnetically driven chemical spraying structure and a hydrodynamic self-rotating cleaning structure: when a large amount of scale accumulates inside the water storage tank body, the magnetically driven chemical spraying structure evenly sprays descaling agent, ensuring that the chemical agent fully penetrates the stubborn scale layer; subsequently, the hydrodynamic self-rotating cleaning structure is activated, using pressurized water flow to form a spiral rinsing trajectory, peeling off scale 360° without dead angles. This automated combination design completely replaces the inefficient traditional manual descaling mode, avoiding physical damage to the inner wall of the equipment caused by manual operation, and enabling periodic rapid maintenance through preset programs, significantly improving cleaning efficiency while ensuring the continuous and stable operation of the water storage tank body.

Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical water storage equipment, specifically to an autonomous descaling mechanism inside a water storage tank. Background Technology

[0002] Water storage tanks are sealed containers used for temporary or long-term storage of water resources, widely used in household, industrial, and public water supply systems. In the pharmaceutical industry, their core function is to serve as high-standard storage units for pharmaceutical water, ensuring that production water meets pharmaceutical-grade purity requirements. They directly participate in key processes such as drug preparation, equipment cleaning, and process water usage. However, after prolonged water storage, pharmaceutical water tanks are prone to large amounts of scale buildup on their inner walls. Calcium and magnesium deposits can not only breed microorganisms or precipitate metal ions, leading to cross-contamination of drugs, but also corrode the stainless steel inner walls, shortening the tank's lifespan, affecting temperature control accuracy, and potentially violating the strict GMP standards of the pharmaceutical industry due to substandard water quality. Traditional manual cleaning methods often result in incomplete cleaning due to blind spots and are time-consuming, easily delaying subsequent production processes. Therefore, using professional methods such as physical cleaning or chemical treatment to regularly remove scale has become a key measure to ensure the quality of pharmaceutical water, reduce the risk of excessive microbial levels in products, and ensure production compliance. While existing technologies may already offer solutions to the above problems, this paper aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: an internal self-descaling mechanism for a water storage tank, comprising: a water storage tank body, an inlet valve, and an outlet valve, wherein the outlet valve is installed on the water storage tank body, the inlet valve is installed on the water storage tank body, a hydrodynamic self-rotating cleaning structure is installed inside the water storage tank body, and a magnetically driven agent spraying structure is installed on the water storage tank body; the hydrodynamic self-rotating cleaning structure comprises: a flushing water pipe, a pair of connecting flushing bearings, a pair of connecting flushing columns, and several branch flushing heads;

[0004] The flushing water pipe is inserted into the main body of the water storage tank, a pair of connecting flushing bearings are respectively installed on the flushing water pipe, a pair of connecting flushing columns are respectively installed on a pair of connecting flushing bearings, and several branch flushing heads are respectively installed on a pair of connecting flushing columns;

[0005] It should be noted that, as described above, the inlet pipe is connected to the inlet valve, and the outlet pipe is connected to the outlet valve. Clean water enters the main body of the water storage tank from the inlet valve, thus completing the water storage operation. When descaling is required inside the main body of the water storage tank, the water inside the main body is first drained. Then, the magnetic power agent spraying structure is activated to spray descaling agent into the main body of the water storage tank. After being sprayed and soaked by the descaling agent, the scale will loosen and soften. Then, through the drain port set on the main body of the water storage tank, the scale inside the main body of the water storage tank is thoroughly removed. The sludge and dirt are cleaned out from the drain port, while stubborn scale is transported through the flushing water pipe to a pair of connecting flushing columns, and then through the connecting flushing columns... The flushing water is evenly sprayed into the main body of the water tank through multiple branch flushing heads. Under the action of water pressure, the sprayed flushing water drives a pair of connecting flushing columns to rotate (when water passes through the internal pipes of the nozzle, two forces are generated: one is the reaction thrust generated when the water flows out of the nozzle at a specific angle, which is opposite to the direction of the water spray. Therefore, the reaction thrust generated by multiple branch flushing heads drives a pair of connecting flushing columns to rotate). The pair of connecting flushing columns, which rotate on a pair of connecting flushing bearings, will use the multiple branch flushing heads on them to flush away the stubborn scale in the main body of the water tank from multiple angles. Then, the scale is cleaned and discharged to the outside through the drain outlet, thus completing the scale removal operation in the main body of the water tank.

[0006] Preferably, the magnetically driven agent spraying structure includes: a descaling agent storage chamber, a transmission pipeline, an internal rotary pipe, a connecting bearing hoop, several branch spray heads, a transmission disk, a drive disk, a rotary power housing, and a rotary power motor;

[0007] The descaling agent storage compartment is installed on the main body of the water storage tank, the transmission pipe is installed on the descaling agent storage compartment, the internal rotary pipe is installed inside the main body of the water storage tank and is installed on the connecting bearing hoop, the connecting bearing hoop is installed on the main body of the water storage tank, the transmission pipe is connected to the connecting bearing hoop, several branch spray heads are respectively installed on the internal rotary pipe, the transmission disk is installed on the internal rotary pipe, the drive disk is installed on the rotary power motor, the rotary power motor is installed inside the rotary power housing, and the rotary power housing is installed on the main body of the water storage tank;

[0008] It should be noted that, as described above, the descaling agent is added into the descaling agent storage tank through the injection port. Then, the descaling agent is pumped into the transmission pipeline by the booster pump on the descaling agent storage tank, and then transmitted to the connecting bearing hoop through the transmission pipeline, and finally to the rotary tube inside the tank. After that, it is sprayed out from multiple branch spray heads. At the same time, the rotary motor inside the rotary power housing drives the drive disk to rotate, which in turn drives the transmission disk to rotate through magnetic force. The rotating transmission disk drives the rotary tube inside the tank to rotate, and the rotary tube inside the tank rotates stably by relying on the connecting bearing hoop. At this time, the multiple branch spray heads evenly spray the descaling agent into the main body of the water storage tank, thereby breaking down the stubborn scale inside the main body of the water storage tank.

[0009] Preferably, the descaling agent storage tank is equipped with a booster pump;

[0010] Preferably, the descaling agent storage compartment is provided with a liquid injection port;

[0011] Preferably, the rotary power housing is provided with a maintenance and inspection port;

[0012] Preferably, the water storage tank body is provided with a drain outlet.

[0013] Beneficial effects

[0014] This invention provides an autonomous descaling mechanism for the interior of a water storage tank. It offers the following advantages: Compared to existing technologies, this autonomous descaling mechanism achieves a convenient and rapid descaling process through the coordinated operation of a magnetically driven chemical spraying structure and a hydrodynamic self-rotating cleaning structure. When a large amount of scale accumulates inside the water storage tank, the magnetically driven chemical spraying structure evenly sprays descaling agent, ensuring that the chemical agent fully penetrates the stubborn scale layer. Subsequently, the hydrodynamic self-rotating cleaning structure activates, using pressurized water flow to form a spiral rinsing trajectory, removing scale 360° without dead angles. This automated combination design completely replaces the inefficient traditional manual descaling method, avoiding physical damage to the inner wall of the equipment caused by manual operation, and enabling periodic rapid maintenance through preset programs. This significantly improves cleaning efficiency while ensuring the continuous and stable operation of the water storage tank. Attached Figure Description

The magnetically driven chemical spraying structure includes: a descaling agent storage chamber 8, a transmission pipe 9, and an internal rotating... The system comprises a pipe 10, a connecting bearing clamp 11, several branch spray heads 12, a transmission disk 13, a drive disk 14, a rotary power housing 15, and a rotary power motor 16. The descaling agent storage compartment 8 is installed on the water storage tank body 1. The transmission pipe 9 is installed on the descaling agent storage compartment 8. The internal rotary pipe 10 is installed inside the water storage tank body 1 and is mounted on the connecting bearing clamp 11. The connecting bearing clamp 11 is mounted on the water storage tank body 1. The transmission pipe 9 is connected to the connecting bearing clamp 11. Several branch spray heads 12 are respectively installed on the internal rotary pipe 10. The transmission disk 13 is installed on the internal rotary pipe 10. The drive disk 14 is mounted on the rotary power motor 16. The rotary power motor 16 is installed inside the rotary power housing 15. The rotary power housing 15 is mounted on the water storage tank body 1.

[0023] According to the appendix Figure 1-3The solution involves connecting the inlet pipe to inlet valve 2 and the outlet pipe to outlet valve 3. Clean water enters the water storage tank body 1 through inlet valve 2, thus completing the water storage operation. When descaling is required inside the water storage tank body 1, the water inside is first drained. Then, the magnetic spraying mechanism is activated to spray descaling agent into the water storage tank body 1. After being sprayed and soaked by the descaling agent, the scale will loosen and soften. Finally, the scale inside the water storage tank body 1 is thoroughly removed through the drain port provided on the water storage tank body 1, and the sludge and dirt are cleaned out through the drain port. Clean water is used to remove stubborn scale, while flushing water pipe 4 delivers external flushing water to a pair of connecting flushing columns 6. From there, the flushing water is evenly sprayed into the main body of the water storage tank 1 through multiple branch flushing heads 7. The sprayed flushing water, under water pressure, causes the pair of connecting flushing columns 6 to rotate. (When water passes through the internal pipes of the nozzles, two forces are generated: one is the reaction thrust generated when the water flows out from the nozzle at a specific angle, which is opposite to the direction of the water spray; the other is the reaction thrust generated by the multiple branch flushing heads 7, which pushes the pair of connecting flushing columns 6.) The rotating column 6, relying on a pair of rotating connecting flushing bearings 5, uses multiple branch flushing heads 7 to flush away stubborn scale from the main body 1 of the water storage tank from multiple angles. The scale is then discharged to the outside through the drain outlet, thus completing the scale removal operation inside the main body 1 of the water storage tank. Descaling agent is added to the descaling agent storage chamber 8 through the injection port. Then, the booster pump on the descaling agent storage chamber 8 pumps the descaling agent into the transmission pipe 9, which then transmits it to the connecting bearing hoop 11, and finally... The solution is delivered into the rotating tube 10 inside the tank, and then sprayed out from multiple branch spray heads 12. At the same time, the rotating power motor 16 inside the rotating power housing 15 drives the drive disk 14 to rotate. The drive disk 14 controls the rotation of the transmission disk 13 through magnetic force. The rotating transmission disk 13 drives the rotating tube 10 inside the tank to rotate. The rotating tube 10 inside the tank rotates stably by relying on the connecting bearing hoop 11. At this time, the multiple branch spray heads 12 spray the descaling agent evenly into the main body of the water storage tank 1, thereby breaking down the stubborn scale inside the main body of the water storage tank 1.
