Description

Technical Field

[0001] This invention belongs to the field of solid disinfectant dosing, and specifically relates to a device for dosing solid calcium hypochlorite disinfectant. Background Technology

[0002] Currently, there are two main methods for adding calcium hypochlorite: 1. Dissolving granular solid calcium hypochlorite disinfectant in a dissolving tank and then adding it using a metering pump; 2. Dissolving cake / tablet solid calcium hypochlorite disinfectant using a water spray and then adding the solution using a water jet pump.

[0003] The former has the following problems:

[0004] I. Problems with the dissolving tank itself: Uneven dissolution, with concentrations fluctuating. Calcium hypochlorite has limited solubility and easily settles to the bottom. Insufficient stirring results in a clear upper layer and a concentrated lower layer. The concentration pumped by the metering pump is unstable. At the same time, the bottom of the dissolving tank is severely sludge, caking, insoluble impurities, calcium carbonate, and reaction precipitates accumulate over time, reducing the effective volume and increasing the load on the agitator. Cleaning the tank is particularly dirty and laborious. Furthermore, the effective chlorine naturally decreases over time. The effective chlorine decreases with prolonged storage of the prepared drug, making the dosage increasingly inaccurate and requiring frequent reconstitution.

[0005] 2. Problems with metering pump pipelines: Check valves and pump heads are frequently blocked by crystallization, and crystallization is also very easy to occur in valve balls and valve seats, resulting in: no metering, fluctuating flow rate, pump running dry, and no medicine being dispensed. Pipelines, elbows, and filters are easily blocked by small residues and crystals, and filter screens become clogged within a few days, requiring frequent disassembly and cleaning.

[0006] III. Safety and Operational Issues: Manual preparation involves contact with highly irritating dust and odors that can irritate the respiratory tract, skin, and eyes. Decomposition of chlorine is present, with an odor that is more pronounced at high pressures, temperatures, and concentrations, posing a safety hazard. Maintenance is extensive, requiring daily monitoring of liquid levels and frequent preparation, necessitating frequent cleaning of pumps, valves, pipelines, and tanks.

[0007] The latter has the following problems:

[0008] I. Dissolution Process: Inherent Defects of Spray Dissolution

[0009] Incomplete dissolution and large concentration fluctuations result in only surface wetting during spraying, leaving internal tablets / granules undissolved and prone to forming a "hard core," leading to low dissolution efficiency. Unstable water pressure / flow and nozzle blockage cause inconsistent dissolution amounts and fluctuating dosage. Calcium hypochlorite contains insoluble impurities (calcium carbonate and calcium chloride), causing residue to accumulate in trays, filters, and bottom chambers after spraying, becoming increasingly thick. This residue clogs spray nozzles, outlets, and return lines, interrupting dissolution and causing a sharp drop in dosage. Poor dry-wet isolation between the reagent compartment and the dissolution chamber allows moisture to rise, causing tablets / granules to absorb moisture, caking, and sticking to the walls, resulting in intermittent dispensing. A small discharge port without an arch-breaking device necessitates frequent manual stirring. After dissolution, the solution remains in the chamber / pipeline, where light and high temperatures accelerate decomposition, rapidly reducing available chlorine and leading to inaccurate dosage.

[0010] II. Dosing and Metering: Insufficient accuracy and stability; unsuitable for applications requiring low chlorine levels.

[0011] The dissolution rate is indirectly controlled by water spraying. Adding via a water jet injector makes it impossible to precisely set the dosage, rendering it unusable in situations requiring only small amounts of disinfectant, such as chlorination in secondary water supply systems. Crystallization can clog nozzles, check valves, dispensing lines, and elbows, leading to no disinfection, sudden drops in flow, and pressure buildup. Residual disinfectant crystals after shutdown will inevitably clog the system upon restart, requiring frequent disassembly and cleaning.

[0012] III. Control and Automation: Weak Closed-Loop Capability

[0013] It relies on external instruments and has low integration. It lacks a built-in residual chlorine sensor, requiring external third-party instruments, resulting in poor compatibility, complex wiring, and a high failure rate. The control logic is simple, mostly timer / on / off control, lacking PID closed-loop control and exhibiting weak anti-interference capabilities. Parameter adjustment is inconvenient and adaptable; it can only adjust the spray flow and feed rate, failing to accurately match pool / water volume, circulation flow rate, and water quality load.

[0014] IV. Maintenance and Operation: High workload, short lifespan

[0015] Frequent cleaning of sludge / nozzles, trays, filters, and nozzles require disassembly and cleaning 1-2 times per week. Sludge cleaning is dirty, tiring, and time-consuming. The dissolving chamber and pipelines need to be thoroughly flushed monthly, otherwise severe scaling will occur and become irreparable.

[0016] V. Safety and Water Quality: Risks and Impacts Remain

[0017] When the dissolution chamber is sealed and the temperature rises, calcium hypochlorite decomposes and releases chlorine gas, increasing the chamber pressure and posing a significant risk of leakage and respiratory irritation. The reagent storage compartment lacks ventilation / explosion-proof design, and the accumulation of chlorine gas poses a risk of poisoning and explosion. Changing the cake solution requires opening the pressure vessel or cartridge, at which point chlorine gas may accumulate inside. Improper operation (such as insufficient venting or failure to wear protective gear) can easily lead to operators inhaling high concentrations of chlorine gas or coming into contact with high concentrations of the reagent solution. Summary of the Invention

[0018] This invention proposes a device for adding solid calcium hypochlorite disinfectant, which can effectively solve the five major problems currently existing in the field of solid calcium hypochlorite addition: dissolution, addition, control, maintenance, and safety.

[0019] Therefore, the technical solution adopted by the present invention is as follows: a device for adding solid calcium hypochlorite disinfectant, comprising an inlet pipe for connecting to a water source and an outlet pipe for outputting a disinfectant solution, wherein a dissolving device for dissolving disinfectant pellets is provided between the inlet pipe and the outlet pipe, and a dosing device for allowing a quantitative amount of pellets to enter the dissolving device is provided above the dissolving device, wherein both the dissolving device and the dosing device are mounted on a mounting plate.

[0020] As a preferred embodiment of the above scheme, the medicine ball has a diameter greater than 5 mm and a hardness greater than 3 kgf / mm². 2 A sphere with a slow-release function.

[0021] Further preferably, the dosing device includes a dosing box and a dosing pipe for dosing into the dissolving device. The dosing box is provided with a hopper for storing medicine balls, and the lower end of the hopper is provided with a dosing outlet for the medicine balls to pass through. A dosing component for quantitative dosing is provided between the dosing pipe and the dosing outlet. The dosing box is provided with a medicine pipe through hole for the medicine pipe to extend and connect with the dissolving device. A protective sleeve is provided on the medicine pipe through hole to ensure the sealing of the dosing box. A desiccant for moisture protection of the medicine balls is provided inside the dosing box.

[0022] Further preferably, the dosing assembly includes a turntable located below the dosing outlet and a drive assembly for rotating the turntable. The turntable is provided with a dosing ball receiving groove for accommodating dosing balls and a sealed receiving groove for accommodating sealed balls. The diameter of the sealed balls is larger than the inner diameter of the dosing pipe. An eccentric plate that does not coincide with the center of the turntable is provided on the turntable, and a clearance groove for the eccentric plate to rotate is provided on the hopper.

[0023] In a further preferred embodiment, the drive assembly includes a rotary motor, and the turntable is provided with a rotary cylinder for the output end of the rotary motor to extend into and connect to. The end of the rotary cylinder away from the rotary motor is mounted on a support member via a bearing, and the support member is mounted on a hopper.

[0024] In a further preferred embodiment, the turntable is provided with a positioning post to ensure that the sealing ball falls above the dispensing tube to achieve a seal, and the hopper is provided with a positioning switch for sensing the positioning post via a fixed bracket.

[0025] In a further preferred embodiment, the outer periphery of the turntable is provided with an anti-detachment guide rail to prevent the medicine ball or sealed ball from detaching from the corresponding receiving groove.

[0026] In a further preferred embodiment, the dispensing tube is equipped with a quantity detection sensor for detecting whether any medicine balls have fallen or for accumulating the number of medicine balls that have fallen.

[0027] Further preferably, the dissolving device includes a dissolving device mounted on a mounting plate via a dissolving device bracket. The dissolving device has an inlet end for communicating with an inlet pipe and an outlet end for communicating with an outlet pipe. The inlet end has an inlet channel, and the outlet end has an outlet channel. A vertical dissolving channel for the drug ball to enter is provided inside the dissolving device. The end of the inlet channel away from the inlet pipe is connected to the lower end of the dissolving channel. A dissolving device cup is threadedly connected to the lower end of the dissolving device. A mixing chamber is provided inside the dissolving device cup and is connected to the outlet channel. A support mesh located at the lower end of the dissolving channel in the mixing chamber is provided to ensure that the drug ball can be fully dissolved.

[0028] Further preferably, the lower end of the dissolving vessel cup is provided with a residue discharge device for cleaning drug residue. The residue discharge device includes a residue discharge pipe mounted on the mounting plate via a residue discharge bracket. The lower end of the dissolving vessel cup is provided with a residue discharge port connected to the residue discharge pipe. The upper end of the residue discharge pipe is provided with an automatic valve for determining whether the residue discharge pipe and the residue discharge port are connected. The automatic valve is connected to the lower end of the dissolving vessel cup via a flexible joint. The lower end of the support net rests at the bottom of the mixing chamber.

[0029] In a further preferred embodiment, the front end of the water inlet pipe is provided with a disinfectant detection device for detecting the disinfectant content in the water pipe, and the disinfectant detection device is mounted on the mounting plate via a sensor bracket.

[0030] The beneficial effects of this invention are:

[0031] 1) When the disinfectant content in the water source is insufficient, the dosing device will add solid disinfectant balls to the dissolving device. By dissolving the disinfectant balls, the disinfectant content will be increased, thereby ensuring that the residual chlorine in the water source meets the requirements.

[0032] 2) In this application, a flowing water stream that can fully immerse the medicine balls is used to achieve automatic dissolution of the solid medicine balls. This not only ensures that the medicine balls are dissolved evenly, but also ensures that the solid medicine balls are fully dissolved. This ensures that the dosage is fully guaranteed during metering, and the dissolution is carried out when needed, which can also effectively guarantee the amount of available chlorine.

[0033] 3) Using running water for dissolution can significantly reduce the accumulation of precipitates at the dissolution site, reducing cleaning work. In addition, this application is also equipped with an automatic residue discharge device, which automatically discharges insoluble matter after the drug balls are dissolved, further preventing the accumulation of precipitates and thus reducing the frequency of cleaning.

[0034] 4) In the entire device, as long as a fixed amount of medicine balls is added into the silo, automatic feeding and automatic slag discharge can be achieved, so that frequent addition of medicine and cleaning are not required, thereby effectively reducing safety hazards.

[0044] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0045] like Figures 1-8 As shown, a device for adding solid calcium hypochlorite disinfectant mainly consists of an inlet pipe 1, an outlet pipe 2, a mounting plate 3, a dissolving device, and a dosing device. The inlet pipe 1 connects to a water source, and the outlet pipe 2 outputs the disinfectant solution. The dissolving device is located between the inlet pipe 1 and the outlet pipe 2 to dissolve the disinfectant pellets. The dosing device is positioned above the dissolving device to allow a measured amount of disinfectant pellets to enter the dissolving device. For ease of installation, both the dissolving device and the dosing device are mounted on the mounting plate 3.

[0046] Specifically, the dosing device includes a dosing box 4 and a dosing pipe 5 for dosing the dissolving device. A hopper 6 for storing the drug balls is provided inside the dosing box 4, and a dosing outlet 6b for the drug balls 9 to pass through is provided at the lower end of the hopper 6. In order to achieve quantitative dosing, a dosing component for quantitative dosing is provided between the dosing pipe 5 and the dosing outlet 6b.

[0047] To facilitate connection between the dispensing pipe and the dissolving device, a through-hole for the dispensing pipe is provided on the dosing box 4. To ensure the sealing of the dosing box, a protective sleeve 7 is installed over the through-hole. For easy addition of desiccant balls to the hopper, the dosing box is equipped with a door that can be opened and closed. Ideally, a platform for placing the desiccant is provided on the hopper.

[0048] The dosing assembly includes a turntable 8 located below the dosing outlet 6b and a drive assembly for rotating the turntable 8. The turntable 8 is equipped with a ball-receiving groove 8a for accommodating drug balls 9 and a sealed groove 8b for accommodating sealed balls 10. The inner diameter of the ball-receiving groove matches the drug ball, ensuring that only a single drug ball can be held in each groove. During the turntable's rotation, the ball-receiving groove transports the drug balls from the hopper to above the dosing pipe. Then, under gravity, the drug balls flow through the dosing pipe into the dissolving device for dissolution. In this embodiment, one ball-receiving groove is provided, and the ball-receiving groove and the sealed groove are positioned opposite each other. In actual use, multiple ball-receiving grooves can be provided on the turntable according to the dosing requirements and the diameter of the drug balls, allowing multiple drug balls to be added with each rotation.

[0049] The diameter of the sealed ball 10 is larger than the inner diameter of the dispensing pipe 5. This not only prevents the sealed ball from falling into the dispensing pipe during the rotation of the turntable, but also prevents moisture in the dissolving device from entering the silo along the dispensing pipe when the sealed receiving tank is located directly above the dispensing pipe.

[0050] An eccentric plate 28 that does not coincide with the center of the turntable is provided on the turntable 8, and a relief groove 6a for the eccentric plate 28 to rotate is provided on the hopper 6. When the turntable rotates under the action of the drive component, the eccentric plate rotates eccentrically, so that the eccentric plate can loosen the medicine balls in the hopper through the relief groove, thereby preventing the medicine balls from caking.

[0051] The drive assembly includes a rotary motor 11. A rotary cylinder 8c is provided on the turntable 8 for the output end of the rotary motor to extend into and connect to. The end of the rotary cylinder 8c away from the rotary motor is mounted on a support member 13 via a bearing 12. The support member 13 is mounted on the hopper 6. To prevent the medicine balls and sealed balls from detaching from their corresponding receiving slots during the rotation of the turntable, an anti-detachment guide rail 17 is provided on the outer periphery of the turntable 8. In this embodiment, the medicine outlet pipe is mounted on the anti-detachment guide rail, which is mounted on the support member. Mounting slots for adjusting the gap between the anti-detachment guide rail and the turntable are provided on the support member or the anti-detachment guide rail.

[0052] Initially, the sealed receiving tank is located directly above the dispensing pipe, and the sealing ball blocks the dispensing pipe to prevent moisture from the dissolving device from entering the hopper along the dispensing pipe. When medication is needed, the drive assembly rotates the turntable, and the medication balls in the hopper fall into the receiving tank. As the turntable continues to rotate, the receiving tank is rotated above the dispensing pipe, and the medication balls, under gravity, enter the dissolving device along the dispensing pipe to dissolve. The turntable continues to rotate, bringing the sealed receiving tank directly above the dispensing pipe. At this point, the positioning switch detects the positioning post, the controller stops the turntable's rotation, and the sealing ball blocks the dispensing pipe, ensuring the sealing of the entire dispensing device.

[0053] Ideally, an arc-shaped plate 8d is provided on the turntable at a position between the two receiving slots to block the dispensing port 6b.

[0054] To prevent the sealing ball from being positioned above the dispensing pipe and blocking it when no medicine is added, the turntable 8 is equipped with a positioning post 14 to ensure that the sealing ball falls above the dispensing pipe to achieve a seal. Correspondingly, a positioning switch 16 for sensing the positioning post is installed on the hopper via a fixed bracket 15.

[0055] To facilitate timely addition of medicine balls to the hopper and ensure that medicine balls enter the dissolving device, a quantity detection sensor 18 is installed on the medicine outlet pipe 5 to detect whether medicine balls have fallen or to accumulate the number of medicine balls that have fallen.

[0056] The dissolving device includes a dissolving vessel 20 mounted on a mounting plate 3 via a dissolving vessel bracket 19. The dissolving vessel 20 has an inlet end for communication with an inlet pipe 1 and an outlet end for communication with an outlet pipe 2. The inlet end has an inlet channel 20a, and the outlet end has an outlet channel 20b. To dissolve the medicine balls, a vertical dissolving channel 20c is provided inside the dissolving vessel 20 for the medicine balls to enter. The upper end of the dissolving channel is aligned with the lower end of the outlet pipe. The end of the inlet channel 20a furthest from the inlet pipe is connected to the lower end of the dissolving channel 20c, allowing the incoming water to mix with the medicine balls and achieve dissolution.

[0057] To facilitate the dissolution of the drug pellets, a dissolving cup 21 is threadedly connected to the lower end of the dissolving device 20. A mixing chamber 21a is provided inside the dissolving cup, and the mixing chamber 21a communicates with the water outlet channel 20b. A support mesh 22 is also provided inside the mixing chamber 21a at the lower end of the dissolving channel to ensure the drug pellets are fully dissolved. Preferably, the connection between the water outlet channel and the mixing chamber is located at the upper end of the mixing chamber.

[0058] To automatically clean the residue left after the dissolving pills, a residue discharge device is installed at the lower end of the dissolving vessel cup 21. The residue discharge device includes a residue discharge pipe 24 mounted on the mounting plate 3 via a residue discharge bracket 23. A residue discharge port connected to the residue discharge pipe 24 is located at the lower end of the dissolving vessel cup 21. An automatic valve 25, controlling the connection between the residue discharge pipe and the residue discharge port, is installed at the upper end of the residue discharge pipe 24. The automatic valve 25 is connected to the lower end of the dissolving vessel cup 21 via a union, and the lower end of the support net 22 rests at the bottom of the mixing chamber. When the automatic valve opens, the residue can be discharged along the support net and residue discharge pipe by flushing with water. The dissolving vessel cup and the dissolving apparatus are connected by threads, and the automatic valve is connected to the dissolving vessel cup via a union, facilitating disassembly and cleaning of the dissolving vessel cup.

[0059] A disinfectant detection device 26 for detecting the disinfectant content in the water pipe is installed at the front end of the water inlet pipe 1, and the disinfectant detection device 26 is mounted on the mounting plate 3 via a sensor bracket 27. The disinfectant detection device adopts existing technology. When the disinfectant detection device detects that the disinfectant content in the water pipe is not up to standard, it causes the drive component to drive the turntable to rotate, thereby adding the disinfectant ball.

[0060] To facilitate control of the entire system, a control device is installed inside the feeding box. This device includes a processor with information processing, reception, and transmission functions, and a display screen with information interaction and display functions. Both the display screen and the processor utilize existing technology. The display screen, disinfectant detection device, rotating motor, positioning switch, quantity detection sensor, and disinfectant detection sensor are all electrically connected to the processor. When the disinfectant detection sensor detects insufficient disinfectant content, the processor, upon receiving this signal, sends a signal to the rotating motor, causing it to operate and thus adding the disinfectant pellets.
