[0026] like Figures 1 to 5 As shown, a fully automatic dosing equipment for a water purification system, the bottom of the dosing hopper 2 is connected to the mixer 4 through a screw conveyor 3, a protruding guide groove 201 is provided on one side of the dosing hopper 2, and a plurality of inclined bag-cutting knives 202 are provided inside the guide groove 201, the cross-section of the bag-cutting knife 202 is in the shape of a water drop, and the cross-sectional area of ​​the bag-cutting knife 202 increases from the upper end to the lower end, and the lower end of the bag-cutting knife 202 has an arc-shaped chamfered structure, the blade of the bag-cutting knife 202 faces upward, and a mesh plate 204 is also provided in the middle of the dosing hopper 2.

[0027] The design of the medicine adding hopper 2 integrates an innovative automatic bag breaking mechanism. When the medicine bag (1) slides in through the guide groove (201), it encounters a series of inclined bag cutting knives (202). These bag cutting knives have a special teardrop-shaped cross-section, and the cross-sectional area gradually increases from the upper end to the lower end, and the blade is upward. This design can not only ensure that the bag is gradually cut open during the sliding process of the medicine bag, but also reduce the risk of the medicine bag being stuck due to the shape of the blade and the rounded structure.

[0028] The arrangement of the bag-cutting knife 202 and the design of the guide groove 201 allow the drug powder to fall smoothly into the drug-adding hopper (2), while the empty drug bags are naturally separated by gravity and fall onto the mesh plate 204 below. This design reduces the need for manual operation, improves work efficiency, and also reduces the risk of operators being exposed to chemicals.

[0029] The screw conveyor 3 connected to the bottom of the dosing hopper is a common solid material conveying equipment, which can evenly and continuously convey the powder in the dosing hopper to the mixer 4 to achieve effective mixing of the drug with water or other treatment liquids. This process has a high degree of automation, ensuring the accuracy of drug addition and the uniformity of mixing, which is crucial to the water purification effect.

[0030] The screen 204 is designed to capture incompletely broken drug bags or residual drug bag fragments for subsequent cleaning, keeping the interior of the device clean and avoiding blockage or contamination caused by residual drug powder. By regularly cleaning the waste on the screen, the system can be maintained to operate continuously and efficiently.

[0031] In the preferred embodiment, the lower ends of the plurality of bag cutting knives 202 are connected by a mounting frame 203, and the plurality of bag cutting knives 202 are arranged at the bottom of the guide groove 201 through the mounting frame 203. The plurality of bag cutting knives 202 are arranged in parallel, and the plurality of bag cutting knives 202 are welded to the mounting frame 203. The integral mounting frame 203 can be disassembled.

[0032] The multiple bag cutting knives 202 are connected as an integral unit and fixed to the bottom of the guide groove 201 through the mounting frame 203. Such a design is conducive to improving the stability and consistency of the system. The parallel arrangement between each bag cutting knife ensures that each position of the medicine bag can be effectively cut during the sliding process, thereby improving the bag breaking efficiency and the uniformity of the medicine powder release.

[0033] The detachable feature of the mounting frame 203 is an important maintenance advantage. During routine maintenance or when the bag cutters need to be replaced, the operator does not need to handle each bag cutter one by one, but can directly disassemble the entire mounting frame for centralized maintenance or replacement of parts, which greatly simplifies the maintenance process, shortens downtime, and improves the maintainability of the system and the reliability of long-term operation.

[0034] The bag cutting knife 202 is fixed to the mounting frame 203 by welding, which ensures the stability during continuous operation and the passage of materials, prevents the bag cutting knife from being displaced or damaged due to vibration or material impact, and enhances the overall durability of the equipment.

[0035] In a preferred embodiment, the mounting frame 203 is welded or arranged at the bottom of the guide groove 201 by a plurality of clamping screws 205 , and the upper end surface of the clamping screws 205 is flush with the surface of the mounting frame 203 .

[0036] The mounting frame 203 can be welded or fixed to the bottom of the guide groove 201 by multiple clamping screws 205. Welding provides a permanent and firm connection method, which is suitable for long-term fixed use and does not require frequent disassembly and assembly. The option of clamping screws increases the flexibility of the installation method, facilitating quick on-site adjustments or possible future repairs and replacements without the need for professional welding tools, reducing maintenance costs and difficulties.

[0037] The design that the upper end surface of the clamping screw 205 is flush with the surface of the mounting frame 203 not only ensures the flatness of the inside of the device, avoids the possibility of hooking or abrasion of the medicine bag caused by the protruding parts, but also ensures the beauty and cleaning convenience of the device. Such detailed processing reduces potential operating obstacles and improves the overall smoothness and safety.

[0038] In the preferred embodiment, an inclined surface is provided on the upper end surface of the mounting frame 203. The inclined surface can effectively prevent the powder material from accumulating on the upper end surface of the mounting frame.

[0039] In the preferred embodiment, at least a plurality of bag scooping rods 8 are provided on one side of the medicine adding hopper 2. The plurality of bag scooping rods 8 are arranged in parallel, and the ends of the plurality of bag scooping rods 8 are connected to a motor 9. The motor 9 rotates to drive the bag scooping rods 8 to scoop out the empty medicine bag from the medicine adding hopper 2. Figure 4As shown, when in use, the multiple bag scooping rods 8 are tilted toward the mesh plate 204 of the medicine adding hopper 2, and the medicine bag 1 slides down onto the multiple bag scooping rods 8. When the medicine powder in the medicine bag 1 leaks out, the motor 9 drives the multiple bag scooping rods 8 to shake, and then rotate to scoop the medicine bag 1 out of the inside of the medicine adding hopper 2.

[0040] In a preferred embodiment, the bottom of the medicine adding hopper 2 is connected to the support frame 5 , and the driving end of the screw conveyor 3 is arranged on the support frame 5 .

[0041] The bottom of the dosing hopper 2 is connected to the support frame 5. This design ensures the stability of the dosing hopper when carrying powder and performing dosing operations. As the basic support part of the entire device, the support frame is responsible for bearing the weight of the dosing hopper and its contents, preventing the equipment from deformation or displacement due to gravity load, and ensuring the reliability and safety of the long-term operation of the equipment.

[0042] The driving end of the screw conveyor 3 is arranged on the support frame 5. The support frame is used as the installation base of the screw conveyor driving system to ensure the stable installation of the driving system and reduce the vibration and noise during operation.

[0043] Such a layout facilitates maintenance and overhaul, because the drive end usually includes key components such as the motor and reducer. Placing them in an easily accessible location can simplify maintenance work and reduce downtime.

[0044] In the preferred embodiment, a plurality of vibrators 6 are further provided on the outer surface of the dosing hopper 2. The vibrators 6 can effectively reduce the agglomeration or adhesion of the powder inside the dosing hopper by generating regular or intermittent vibrations, and promote the smooth flow of the powder. This is very important to ensure the continuity and dosage accuracy of the dosing process, especially when dealing with hygroscopic and agglomerated powders.

[0045] By using vibration to assist in feeding, the transfer speed of the powder from the dosing hopper 2 to the screw conveyor 3 can be accelerated, thereby improving the overall dosing efficiency.

[0046] In the preferred embodiment, an electric valve plate 7 is further provided between the dosing hopper 2 and the screw conveyor 3. The electric valve plate 7 between the dosing hopper 2 and the screw conveyor 3 is a controllable switch, and opening and closing directly controls whether the powder can enter the screw conveyor from the dosing hopper. It can be opened accurately when dosing is needed, and closed after dosing is completed, so as to avoid continuous and uncontrolled outflow of powder, thereby realizing dosing on demand and enhancing the controllability and accuracy of the dosing process.

[0047] In the preferred embodiment, a control box is also provided, which is electrically connected to the electric valve plate 7 and the screw conveyor 3. The control box serves as the command center of the entire dosing system. It is electrically connected to the electric valve plate 7 and the screw conveyor 3. Through a preset program or remote command, it can automatically control the opening and closing timing of the electric valve plate and the working state of the screw conveyor. The control box can not only set the start and end time of delivering the medicine, but also adjust the delivery rate according to the processing requirements, thereby achieving precise control of the dosage and meeting the dosing requirements under different working conditions.

[0048] Through the intelligent control of the control box, the precise dosage of the required reagents can be automatically calculated and executed according to the actual water volume or water quality monitoring results, avoiding errors caused by human operation, saving reagent consumption, improving treatment efficiency, and ensuring the consistency and reliability of the purification effect. This quantitative dosing method is of great significance for maintaining stable water quality, reducing operating costs, and improving the level of automated management.

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
