Description

Technical Field

[0001] This application relates to the technical field of water treatment, and in particular to a device for feeding corrosion and scale inhibitors. Background Technology

[0002] Corrosion and scale inhibitors are the main treatment agents in industrial circulating water and boiler water systems. Their raw materials are mostly powder or paste mixtures, often containing mechanical impurities and particulate agglomerates. Furthermore, the raw materials are prone to clumping due to temperature and humidity changes. During the production process, insufficient purity or poor flowability of the raw materials can lead to blockages in the conveying pipelines and uneven feeding into the reactor, thereby affecting the stability of product quality.

[0003] Existing corrosion and scale inhibitor feeding devices mostly adopt a single filtration structure, such as a fixed filter screen, which has low filtration accuracy and the quality of corrosion and scale inhibitor feeding is highly affected by impurities; moreover, single filters are easily clogged by agglomeration, resulting in low conveying efficiency. Utility Model Content

[0004] In order to improve the problems of low filtration accuracy and easy blockage by agglomeration in the single filter structure of corrosion and scale inhibitor feeding devices, this application provides a corrosion and scale inhibitor feeding device.

[0005] This application provides a corrosion and scale inhibitor feeding device, which adopts the following technical solution: A corrosion and scale inhibitor feeding device includes a raw material cylinder for storing corrosion and scale inhibitor material, a hydrocyclone separator, a screw feeder, and a reaction vessel. The input end of the hydrocyclone separator is connected to the raw material cylinder through a first valve, and the output end of the hydrocyclone separator is connected to a filter pipe through a second valve. The feed end of the screw feeder is connected to the other end of the filter pipe, and the discharge end of the screw feeder is connected to a vibrating screen pipe. The other end of the vibrating screen pipe is connected to a backwash water tank, and a vibration component is installed on the vibrating screen pipe. A third valve is installed at the outlet end of the backwash water tank, and an output pipe is provided between the vibrating screen pipe and the backwash water tank. The reaction vessel is installed at the bottom of the output pipe and is connected to the output pipe. A feed valve is provided at the feed end of the reaction vessel.

[0006] By adopting the above technical solution, the raw material cylinder provides storage space for the corrosion and scale inhibitor material, ensuring sufficient material supply during the feeding process. The first valve can flexibly control the feed rate from the raw material cylinder to the hydrocyclone separator, avoiding excessive material leading to incomplete hydrocyclone separation. The hydrocyclone separator can initially separate large particles and clumps in the material. The second valve can adjust the conveying speed of the material after hydrocyclone separation to the filter tube, working with the filter tube to perform secondary fine filtration of the material, further removing fine impurities. The screw feeder, through forced conveying, avoids material clogging the pipeline due to clumps during conveying, ensuring continuous feeding. Under the action of the vibration components, the vibrating screen tube can both break up small agglomerates remaining in the material and trap impurities that have slipped through the screen, further achieving purification. The output pipe introduces the purified material into the reactor, and the feed valve can control the feeding time of the reactor, ensuring that the material in the reactor is supplied as needed. The backwash water tank can introduce backwash water into the vibrating screen tube through the third valve to clean the impurities trapped by the screen in a timely manner and prevent screen blockage. Compared to traditional single-filter feeding devices, the entire feeding process of this device significantly improves material purity and feeding efficiency, ensuring the stability of subsequent product quality.

[0007] Optionally, a first limiting plate and a second limiting plate are installed inside the vibrating screen tube, a vibrating screen frame is provided between the first limiting plate and the second limiting plate, a screen is installed on the vibrating screen frame, and the vibration component is installed on the vibrating screen tube.

[0008] By adopting the above technical solution, the first limiting plate and the second limiting plate form a stable installation space, which plays a positioning role for the vibrating screen frame and prevents the screen frame from shifting or falling off during vibration. The vibrating screen frame provides support for the screen, avoiding deformation of the screen due to vibration or material impact and extending the service life of the screen. The screen can be selected with an appropriate mesh size according to the particle size of the material impurities, achieving efficient interception of fine impurities and small agglomerates. The vibration component works in conjunction with the vibrating screen tube to evenly transmit the vibration force to the screen frame and the screen, ensuring that the overall vibration frequency of the screen is consistent, which not only improves the impurity separation efficiency but also avoids local material accumulation, further ensuring the smoothness of material conveying.

[0009] Optionally, the vibration assembly includes a support frame mounted on the vibrating screen tube, a drive component mounted on the support frame, a rotating shaft driven by the output end of the drive component, an eccentric wheel mounted on the rotating shaft, a sleeve mounted on the vibrating screen tube, an action rod for acting on the vibrating screen frame fitted inside the sleeve, the action rod moving up and down along the axial direction of the sleeve, a bracket mounted on the other end of the action rod, a roller rotatably mounted on the bracket and engaging with the eccentric wheel, a spring and a fixing plate fitted on the action rod, the spring being located between the fixing plate and the sleeve, with one end of the spring connected to the fixing plate and the other end connected to the sleeve.

[0010] By adopting the above technical solution, the support frame provides the installation foundation for the drive component, ensuring that the drive component does not shift during operation; the drive component drives the eccentric wheel to rotate through the rotating shaft, and the eccentric structure of the eccentric wheel converts the rotational motion into a periodic pushing force on the roller; the roller and the eccentric wheel are connected, converting sliding friction into rolling friction, reducing component wear, and ensuring smoother force transmission; the sleeve guides the action rod, limiting the action rod to only move up and down along the axial direction, avoiding uneven vibration force caused by the action rod deviating; the action rod applies the force transmitted by the roller to the vibrating screen frame, driving the screen to vibrate; the spring compresses and stores energy when the eccentric wheel pushes the action rod down, and releases elastic potential energy when the eccentric wheel rotates to a non-pushing position, pulling the action rod back to its original position, realizing the reciprocating up and down motion of the action rod, thereby driving the screen to vibrate continuously; the fixed plate provides a force support point for the spring, ensuring that the spring's position is fixed during the extension and contraction process, ensuring the overall stability and continuity of the vibration assembly, and effectively improving the impurity separation and anti-clogging effect of the screen.

[0011] Optionally, the hydrocyclone separator includes a cylindrical section and a conical section connected to the cylindrical section, with the other end of the cylindrical section connected to the raw material cylinder and the other end of the conical section connected to the filter tube.

[0012] By adopting the above technical solution, the cylindrical section provides a stable rotation space for the material. After the material enters the cylindrical section from the raw material cylinder, it begins to move in a circular motion under the action of centrifugal force. Large particles of impurities and clumps, due to their higher density, gradually move towards the inner wall of the cylindrical section. The diameter of the conical section gradually decreases along the material flow direction, further enhancing the rotational speed and centrifugal force of the material, causing large particles of impurities and clumps to gather more quickly towards the inner wall and slide down along the inner wall of the conical section to the output end, achieving efficient separation from the pure material. Compared with a single cylindrical structure, this structure has higher separation efficiency and can more thoroughly remove large-sized impurities and clumps from the material, improving the overall purity of the feed.

[0013] Optionally, a filter element is provided inside the filter tube, and a first mounting component and a second mounting component are installed inside the filter tube. One end of the filter element is installed on the first mounting component, and the other end is connected to the second mounting component.

[0014] By adopting the above technical solution, the first mounting component and the second mounting component are spaced apart along the axial direction of the filter tube to form a fixed structure at both ends of the filter element, ensuring that the filter element does not shift or shake under the impact of material flow. The fixed installation method at both ends of the filter element ensures that the filter element is tightly fitted to the inner wall of the filter tube, preventing material from leaking through the gap between the filter element and the tube wall, ensuring that all materials are filtered by the filter element, improving filtration accuracy and reliability, and further ensuring the purity of the material entering the screw feeder.

[0015] Optionally, a conveying pipe is installed between the feed inlet of the filter tube and the output end of the hydrocyclone separator, and a collection tank for storing waste residue is installed at the bottom of the conveying pipe, and the conveying pipe is connected to the collection tank.

[0016] By adopting the above technical solution, the conveying pipe provides a transitional conveying channel for materials between the hydrocyclone separator and the filter pipe. Under the action of gravity, the large particles of waste separated by the hydrocyclone separator will gradually settle to the bottom of the conveying pipe during the material flow. The collection tank is connected to the conveying pipe, which can collect these deposited waste particles in a timely manner, preventing the waste particles from entering the filter pipe with the material and causing filter element blockage, thus extending the service life of the filter element. At the same time, the collection tank can be cleaned regularly, which facilitates the centralized treatment of waste particles by operators, reduces the pollution of other components of the device by waste particles, ensures the continuous and stable operation of the feeding process, and improves the convenience of device maintenance.

[0017] Optionally, flanges are installed at the connection ends of the conveying pipe, the filter pipe, and the vibrating screen pipe.

[0018] By adopting the above technical solution, the flange can be detachably fixed between the components through bolt connection, which is convenient for installation and disassembly. It is also convenient for the internal components (such as filter element and screen) of the conveying pipe, filter pipe and vibrating screen pipe to be inspected, replaced or cleaned later. At the same time, the rigid connection structure of the flange has high strength and can withstand the pressure and vibration during the material conveying process, ensuring that the connection of each component is stable.

[0019] Optionally, the screw feeder is provided with multiple sets of heating jackets.

[0020] By adopting the above technical solution, the heating jacket can generate heat by introducing hot water, steam, or electric heating, and evenly transfer the heat to the inside of the screw feeder to gently heat the corrosion and scale inhibitor material during the conveying process. When the ambient temperature is low or the material is prone to caking due to slightly high humidity, the heating jacket can maintain the material temperature within a suitable flow temperature range, effectively preventing material caking, improving material flowability, and avoiding material blockage in the screw feeder. Multiple sets of heating jackets are evenly distributed along the axial direction of the screw feeder to ensure that the material is heated evenly throughout the entire conveying length, avoiding local overheating and deterioration of the material or local unheated caking, thus ensuring the smoothness of material conveying and the stability of material quality.

[0021] Optionally, the screw feeder is a variable pitch screw feeder.

[0022] By adopting the above technical solution, the blade spacing of the variable pitch screw feeder can be adjusted according to needs along the material conveying direction, such as a larger spacing at the inlet and a smaller spacing at the outlet: the larger blade spacing at the inlet can accommodate more material, enabling rapid feeding and preventing material accumulation at the inlet; as the material is conveyed to the outlet, the gradually decreasing blade spacing can exert a certain squeezing and pushing effect on the material, which can further break up the small agglomerates remaining in the material and ensure that the material is output to the vibrating screen tube at a stable and uniform flow rate, avoiding the vibrating screen tube from not being able to process the material in time due to sudden changes in the material flow rate at the outlet; at the same time, the variable pitch structure can also adapt to the material conveying needs of different flow rates, improve the applicability of the screw feeder, and ensure the continuity and stability of the feeding process.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. This device, through its multi-stage purification structure of hydrocyclone separator, filter tube, and vibrating screen tube, significantly improves the purity of corrosion and scale inhibitor materials compared to traditional single filtration devices. It effectively reduces the impact of mechanical impurities and agglomerates on the conveying pipeline and reactor feed, ensuring the stability of subsequent product quality. At the same time, the forced conveying of the screw feeder, the continuous vibration of the vibrating components, and the anti-clogging cleaning of the backwash tank jointly solve the problems of poor material flowability and easy clogging, improving feeding efficiency. 2. The heating jacket allows for flexible temperature control based on ambient temperature and material characteristics, maintaining the material temperature within a suitable flow temperature range. This effectively prevents material agglomeration, improves material flowability, and avoids material blockage within the screw feeder. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0030] This application discloses a corrosion and scale inhibitor feeding device, referring to... Figure 1 and Figure 2The corrosion and scale inhibitor feeding device includes a raw material cylinder 1 for storing corrosion and scale inhibitor material, a hydrocyclone separator 2, a screw feeder 5, and a reaction vessel 8. The input end of the hydrocyclone separator 2 is connected to the raw material cylinder 1 through a first valve, and the output end of the hydrocyclone separator 2 is connected to a filter pipe 3 through a second valve. The feed end of the screw feeder 5 is connected to the other end of the filter pipe 3, and the discharge end of the screw feeder 5 is connected to a vibrating screen pipe 6. The other end of the vibrating screen pipe 6 is connected to a backwash water tank 91. A vibration component 7 is installed on the vibrating screen pipe 6, and a third valve is installed at the water outlet end of the backwash water tank 91. An output pipe 9 is provided between the vibrating screen pipe 6 and the backwash water tank 91. The reaction vessel 8 is installed at the bottom of the output pipe 9 and is connected to the output pipe 9. A feed valve is provided at the feed end of the reaction vessel 8.

[0031] In this feeding device, the raw material cylinder 1 serves as a storage carrier for the corrosion and scale inhibitor, providing a continuous and stable material source for the entire feeding process. The first valve acts as a material control switch between the raw material cylinder 1 and the hydrocyclone 2. By adjusting the opening of the first valve, the feed rate and speed from the raw material cylinder 1 to the hydrocyclone 2 are controlled, preventing material accumulation from affecting the impurity removal effect. The hydrocyclone 2 utilizes the principle of centrifugal separation, receiving the material conveyed by the raw material cylinder 1 and causing the material to rotate at high speed. Because mechanical impurities and particle agglomerates have a higher density than the pure material, they will move towards the inner wall of the hydrocyclone 2 under the action of centrifugal force, eventually separating from the pure material, removing large-sized impurities and agglomerates, and achieving preliminary purification.

[0032] The filter tube 3 uses filter element 31 to finely filter the material after cyclone separation, trapping fine impurities not removed by the cyclone separator 2, further improving material purity. The screw feeder 5 receives the purified material output from the filter tube 3 and stably conveys it to the vibrating screen tube 6. The rotation of the screw blades propels the material forward, breaking up slight clumps and preventing material buildup during transport, ensuring continuous and uniform material flow and preventing pipe blockage. The second valve connects the cyclone separator 2 and the filter tube 3, regulating the conveying speed and time of the pre-purified material after cyclone separation to the filter tube 3. The feed rate can be flexibly controlled according to the processing status of the filter tube 3. When replacing filter element 31 in the filter tube 3, the second valve can be closed to cut off the material flow, enabling partial maintenance without shutting down the system and improving the continuity of equipment operation.

[0033] The vibrating screen tube 6 uses an internal screen 62 to trap small agglomerates and impurities remaining in the material. Simultaneously, the vibrating assembly 7 provides continuous vibration, preventing impurities from accumulating and clogging the screen 62 surface, further optimizing material purity. Compared to traditional fixed filters, this improves conveying efficiency and eliminates the need for frequent shutdowns for cleaning, reducing operator maintenance costs. The vibrating assembly 7 continuously vibrates to loosen and flow the material on the screen 62 surface, ensuring effective impurity trapping while preventing static accumulation and clogging of the screen 62, maintaining long-term unobstructed flow in the screen tube. Compared to manual cleaning, automated vibration is more efficient, reducing feeding interruptions caused by clogging.

[0034] The backwash water tank 91 can store cleaning water. After long-term use, the vibrating screen tube 6 can be flushed with backwash water to wash away stubborn impurities remaining on the surface of the screen 62 and filter element 31. The water then flows into the waste collection tank 41 through the hydrocyclone separator 2, further extending the continuous working time of the vibrating screen tube 6 and preventing the screen 62 from becoming clogged and the filter from failing due to long-term accumulation of impurities. Compared with disassembly and cleaning, backwash water cleaning is more convenient and can be completed online, reducing downtime and improving feeding efficiency.

[0035] The third valve controls the backwash water tank 91 to deliver backwash water to the vibrating screen tube 6. It can be flexibly opened or closed according to the blockage of the screen 62, adjusting the flushing water volume and duration to achieve precise control of the backwash water and avoid water waste. At the same time, the third valve can be closed during non-cleaning periods to prevent cleaning water from mixing with materials and affecting product quality, ensuring the safety and stability of the equipment operation.

[0036] Output pipe 9 connects vibrating screen pipe 6 and reactor 8, guiding the purified material from vibrating screen pipe 6 to reactor 8, ensuring no leakage and no secondary contamination. The routing of output pipe 9 can be adjusted according to the equipment layout to suit the space requirements of different workshops, improving installation flexibility. Reactor 8 receives the purified material from output pipe 9 and performs subsequent chemical reactions to produce finished products, improving the consistency and pass rate of finished product quality. The feed valve controls the feeding time and amount from output pipe 9 to reactor 8, and can be flexibly adjusted according to the reaction progress within reactor 8, further ensuring reaction stability. When reactor 8 is under maintenance or batch switching is required, the feed valve can be closed to cut off the feed, improving operational safety.

[0037] This corrosion and scale inhibitor feeding device employs a multi-stage purification process: raw material storage, removal of large impurities by a hydrocyclone 2, removal of fine impurities by a filter tube 3, removal of small agglomerates by a vibrating screen tube 6, forced conveying by a screw feeder 5, output pipe 9, and reaction vessel 8. Combined with precise control of multiple valves and anti-clogging features of a backwash tank 91, it achieves efficient impurity removal, stable material conveying, and uniform feeding, improving the consistency and stability of finished product quality and providing a pure and continuous supply of raw materials for corrosion and scale inhibitor production.

[0038] refer to Figure 2 , Figure 3 and Figure 4 A first limiting plate 63 and a second limiting plate 64 are installed inside the vibrating screen tube 6. A vibrating screen frame 61 is provided between the first limiting plate 63 and the second limiting plate 64. Vibration space is reserved between the vibrating screen frame 61 and the first limiting plate 63, the second limiting plate 64 and the wall of the vibrating screen tube 6 to ensure that the vibration of the vibrating screen frame 61 is not hindered. A screen 62 is installed on the vibrating screen frame 61. The vibration assembly 7 is installed on the vibrating screen tube 6. The first limiting plate 63 is an axial positioning component of the vibrating screen frame 61. It is fixedly installed on one side of the inner wall of the vibrating screen tube 6 and cooperates with the second limiting plate 64 to form a stable installation space, which restricts the vibrating screen frame 61 from large displacement along the material conveying direction during vibration and prevents it from falling off, ensuring that the screen 62 vibrates within the preset space. The vibrating screen frame 61 serves as the supporting skeleton for the screen 62. It employs a rigid structure to fix the screen 62 to its own frame, forming a filtration structure. Simultaneously, the vibrating screen frame 61 is directly connected to the vibrating component 7, receiving the vibration force transmitted from the component and evenly distributing it to the entire screen 62. This keeps the material on the surface of the screen 62 continuously loose, preventing impurities from adhering to the screen 62's apertures, maintaining smooth filtration, and improving impurity retention efficiency. Furthermore, the structure of the vibrating screen frame 61 facilitates the disassembly and replacement of the screen 62. When the screen 62 is severely worn or clogged, it can be quickly replaced, reducing maintenance difficulty. The screen 62 further purifies the material through its pre-set aperture, trapping fine particulate impurities and small clumps, thus improving material purity. The aperture of the screen 62 can be flexibly selected according to production needs, adapting to different purity requirements for corrosion and scale inhibitor production scenarios, enhancing the applicability of the device. The vibration component 7 generates vibration force, which is transmitted to the vibrating screen frame 61, causing the screen 62 to vibrate at high frequency and small amplitude. During vibration, the material on the surface of the screen 62 is evenly distributed, and impurities adhering to the aperture of the screen 62 are shaken off, preventing clogging and ensuring more stable filtration accuracy. This reduces feeding interruptions caused by clogging and guarantees the continuity of the entire feeding process. The vibration assembly 7 includes a support frame 71 mounted on the vibrating screen tube 6. A drive component 72 is mounted on the support frame 71. The output end of the drive component 72 is driven to connect to a rotating shaft 73. An eccentric wheel 74 is mounted on the rotating shaft 73. A sleeve 75 is mounted on the vibrating screen tube 6. An action rod 76 for acting on the vibrating screen frame 61 is fitted inside the sleeve 75. The action rod 76 moves up and down along the axis of the sleeve 75. A bracket 77 is mounted on the other end of the action rod 76. A roller 771 that rotatably engages with the eccentric wheel 74 is mounted on the bracket 77. A spring and a fixing plate 78 are fitted on the action rod 76. The spring is located between the fixing plate 78 and the sleeve 75, with one end of the spring connected to the fixing plate 78 and the other end connected to the sleeve 75.

[0039] The support frame 71 provides a support carrier for the drive component 72. The drive component 72 converts electrical energy into mechanical energy and starts, stops, or adjusts the output power according to preset control commands. It drives the rotating shaft 73 to rotate through the output end. The rotating shaft 73 transmits the rotational power output by the drive component 72 to the eccentric wheel 74. The eccentric wheel 74 uses its own eccentric structure to convert the uniform rotational motion transmitted by the rotating shaft 73 into a periodic eccentric thrust. Through docking with the roller 771, the thrust is applied to the roller 771, pushing the action rod 76 to reciprocate up and down along the axis of the sleeve 75. The action rod 76 transmits the vibration force to the vibrating screen frame 61, causing the screen 62 to vibrate. At the same time, the spring assists the action rod 76 to reset and buffer the impact, ultimately achieving continuous and stable vibration of the vibrating screen 62, achieving the purpose of anti-clogging and enhanced filtration.

[0040] The sleeve 75 provides an axial guide channel for the actuating rod 76, restricting the actuating rod 76 to only move up and down along the axis of the sleeve 75. This prevents the actuating rod 76 from shifting laterally or swaying during movement and also protects the actuating rod 76, reducing interference from external impurities. One end of the actuating rod 76 receives the thrust transmitted by the eccentric wheel 74 through the roller 771, and reciprocates up and down along the axis of the sleeve 75. The other end contacts the vibrating screen frame 61, converting the reciprocating up and down motion into vibrational force, which is transmitted to the vibrating screen frame 61, causing the screen 62 to vibrate. This continuous vibration of the screen 62 effectively breaks up agglomerates in the corrosion and scale inhibitor material, shakes off impurities adhering to the surface of the screen 62, reduces impurity accumulation, improves the anti-clogging effect and impurity retention efficiency of the screen 62, ensures continuous and smooth material conveying, and improves overall feeding efficiency. The bracket 77 provides a rotating mounting base for the roller 771, ensuring that the roller 771 can stably mate with the eccentric wheel 74. It also positions the roller 771, maintaining contact between it and the eccentric wheel 74 and preventing the roller 771 from detaching from the eccentric wheel 74 during movement. The roller 771 converts the sliding friction between the eccentric wheel 74 and the actuating rod 76 into rolling friction, reducing frictional resistance and wear, while ensuring that the thrust of the eccentric wheel 74 can be smoothly transmitted to the actuating rod 76.

[0041] When the actuating rod 76 is pushed down by the eccentric wheel 74, the spring is compressed and stores elastic potential energy. When the eccentric wheel 74 rotates to the non-pushing position, the spring releases its elastic potential energy, pulling the actuating rod 76 back up, assisting the actuating rod 76 in reciprocating motion, thus ensuring the continuous vibration of the screen 62. At the same time, the spring acts as a buffer, mitigating the impact force when the actuating rod 76 descends, reducing material splashing caused by excessive vibration, balancing the vibration effect and component protection, and improving the stability of the device operation. The fixed plate 78 is the force support point of the spring. During the lifting and lowering of the actuating rod 76, the fixed plate 78 moves synchronously with the actuating rod 76, providing stable compression and reset support for the spring, limiting the extension and contraction range of the spring, avoiding excessive compression or stretching that could lead to failure, ensuring that the spring can stably follow the movement of the actuating rod 76, and ensuring the spring's effect in assisting the reciprocating motion of the actuating rod 76.

[0042] refer to Figure 1 The hydrocyclone separator 2 includes a cylindrical section 21 and a conical section 22 connected to the cylindrical section 21. The other end of the cylindrical section 21 is connected to the raw material cylinder 1, and the other end of the conical section 22 is connected to the filter tube 3. The cylindrical section 21 receives the corrosion and scale inhibitor material conveyed by the raw material cylinder 1. When the material enters the cylindrical section 21 at a certain speed, it will move in a circular motion along the cylinder wall to form a rotating flow field. The difference in centrifugal force is used to achieve the initial separation of impurities and pure materials. Mechanical impurities and particle agglomerates with higher density move towards the cylinder wall under the action of centrifugal force, while pure materials with lower density gather towards the center of the cylinder. Large-sized impurities and clumps are initially screened out, avoiding these impurities from directly entering the subsequent filter tube 3 and vibrating screen tube 6 and causing blockage. The conical section 22 is the enhanced separation zone of the hydrocyclone 2, and its diameter gradually decreases along the material flow direction. The material entering the conical section 22 will have its rotational speed further increased due to the space contraction, and the centrifugal force will increase accordingly. This will push the fine impurities and small clumps that were not completely separated in the cylindrical section 21 further towards the cone wall, and finally slide down the cone wall to the output end (where it connects to the filter tube 3). Meanwhile, the pure material in the central area will continue to flow towards the output end, completing the secondary separation, which greatly improves the separation accuracy and avoids the impact of impurity residue on product quality stability. The contraction structure of the conical section 22 can also play a guiding role, guiding the separated impurities and pure materials to flow in an orderly manner, preventing them from mixing again, and ensuring the stability of the separation effect. In addition, impurities sliding down the cone wall are less likely to accumulate in the separator, reducing the probability of the separator itself clogging, extending the equipment maintenance cycle, and improving the continuity of the feeding process. refer to Figure 5 , Figure 6 and Figure 7A filter element 31 is installed inside the filter tube 3. A first mounting component 32 and a second mounting component 33 are installed inside the filter tube 3. One end of the filter element 31 is mounted on the first mounting component 32, and the other end is connected to the second mounting component 33. The filter element 31 has fine and regular filtration channels inside, which can perform secondary purification on the material after preliminary separation by the hydrocyclone separator 2. When the material flows through the filter element 31, the filter element 31 can intercept the fine mechanical impurities and micro-particle agglomerates remaining in the material, allowing only pure corrosion and scale inhibitor materials to pass through, further improving the purity of the material. The filter element 31 can be selected according to the purity requirements of the material to adapt to diverse production scenarios. In this application, the filter element 31 is a metal sintered filter element 31, which can be double-layered. The filter element 31 has a gradient pore size to further filter impurities. The outer filter element 31 has a pore size of 50um, and the inner filter element 31 has a pore size of 10um. A flow guide gap is reserved between the two layers to avoid impurity accumulation and blockage.

[0043] The first mounting component 32 serves as a fixing carrier for one end of the filter element 31. It precisely connects to one end of the filter element 31 through a preset connection structure (such as a groove or thread), restricting the displacement of the filter element 31 at that end and ensuring that there are no gaps between the filter element 31 and the inner wall of the filter tube 3, preventing unfiltered material from leaking through the gaps. The second mounting component 33 serves as a fixing carrier for the other end of the filter element 31. It connects to the other end of the filter element 31 through a connection structure that matches the first mounting component 32, forming a bidirectional fixation of the filter element 31. At the same time, it helps to disperse the impact pressure of the material on the filter element 31 during the filtration process, preventing the filter element 31 from being deformed due to excessive local stress.

[0044] A conveying pipe 4 is installed between the feed inlet of the filter pipe 3 and the output end of the hydrocyclone 2. A collection tank 41 for storing waste residue is installed at the bottom of the conveying pipe 4. The conveying pipe 4 is connected to the collection tank 41. The conveying pipe 4 receives the material (containing a small amount of waste residue that has not been completely separated) after the hydrocyclone 2 has initially separated it and guides the material to flow steadily toward the filter pipe 3. At the same time, its inclined or specific angle setting provides space for the gravity deposition of waste residue, so that the waste residue in the material naturally gathers to the bottom of the pipe during the conveying process.

[0045] The collection tank 41 is a special storage container for waste residue, which receives the waste residue that is deposited by gravity in the conveying pipe 4, and realizes the complete separation of waste residue and material. At the same time, the collection tank 41 has an openable or detachable structure, which facilitates the regular cleaning of the waste residue stored inside and prevents the waste residue from overflowing and flowing back into the conveying pipe 4. Flanges are installed at the connection ends of the conveying pipe 4, the filter pipe 3, and the vibrating screen pipe 6. Flanges are installed between each component and pipe fitting, and sealing rings are installed inside the flanges. The flanges are used to tightly connect the connection ends of adjacent pipe fittings or components with bolts and other fasteners to form a rigid connection structure. Its flat connection surface can ensure the coaxiality and sealing of each component when they are connected, and at the same time provide a stable operating basis for the subsequent disassembly and assembly of components, which facilitates the regular inspection and replacement of easily worn components such as the filter element 31 of the filter pipe 3 and the screen 62 of the vibrating screen pipe 6.

[0046] The sealing ring is embedded in the sealing groove of the flange. When the flange is tightened with bolts, the sealing ring is compressed and undergoes elastic deformation, filling the tiny gaps between the flange connection surfaces to form a sealed structure. At the same time, the sealing ring can adapt to a certain range of temperature and pressure changes, maintaining its sealing performance during material transportation, preventing material leakage from the flange connection gap, and preventing external air and impurities from entering the pipeline and contaminating the material, indirectly ensuring the purity and performance stability of the corrosion and scale inhibitor. In addition, the sealing ring can also buffer the vibration and friction between the flange connection surfaces, reducing flange wear, extending flange service life, and reducing the risk of bolt loosening due to vibration, further improving the stability of the connection structure. refer to Figure 1 The screw feeder 5 is equipped with multiple sets of heating jackets 51 and temperature sensors. The feeding device includes a control component, which is electrically connected to the heating jackets 51 and temperature sensors. The heating jackets 51 generate heat by introducing a heat medium (such as hot water or steam) or by electric heating, and evenly transfer the heat to the inside of the screw feeder 5. This gently heats the corrosion and scale inhibitor raw material during the conveying process, maintaining the raw material within a suitable temperature range, ensuring good flowability, and preventing agglomeration due to low temperature. The surrounding arrangement of the heating jackets 51 covers most of the conveying area of ​​the screw feeder 5, ensuring the raw material remains at a suitable temperature throughout the entire conveying process, further reducing the risk of agglomeration.

[0047] The temperature sensor collects the temperature data of the raw material inside the screw feeder 5 in real time and converts the temperature signal into an electrical signal, which is then transmitted to the control component. This prevents overheating or underheating, which could lead to raw material deterioration, performance degradation, or ineffective operation of the heating jacket 51. The control component receives the temperature signal from the temperature sensor and analyzes the temperature data. When the raw material temperature is lower than the set value, it controls the heating jacket 51 to start heating. When the temperature reaches the set threshold, it controls the heating jacket 51 to stop heating or reduce the heating power, thus achieving automatic temperature regulation. This ensures that the raw material temperature remains stable within a suitable range, further reducing the probability of raw material agglomeration and guaranteeing conveying efficiency. The screw feeder 5 is a variable pitch screw feeder 5. The variable pitch screw feeder 5 achieves graded conveying and processing of corrosion and scale inhibitor raw materials by differentiating the spacing of the screw blades along the material conveying direction. The larger blade spacing at the feed end can accommodate more raw materials to be conveyed, reducing the accumulation of raw materials at the feed inlet and ensuring the smoothness of the initial conveying stage. As the conveying process progresses, the gradually decreasing blade spacing generates appropriate squeezing and propulsion force on the raw materials, which can not only break up the slight lumps remaining in the raw materials and improve the flowability, but also control the conveying speed and output of the raw materials, ensuring that the raw materials flow evenly to the subsequent vibrating screen tube 6. The implementation process of the corrosion and scale inhibitor feeding device in this application embodiment is as follows: The operator adds the corrosion and scale inhibitor raw material (powder or paste) to the raw material cylinder 1, opens the first valve, and adjusts the opening of the first valve according to the processing capacity of the hydrocyclone 2 so that the raw material flows from the raw material cylinder 1 into the cylindrical section 21 of the hydrocyclone 2 at a stable flow rate. After the raw material enters the hydrocyclone separator 2, it moves in a circular motion along the cylinder wall in the cylindrical section 21. Larger particles and clumps with higher density move towards the cylinder wall under the action of centrifugal force and flow with the material to the conical section 22. The diameter of the conical section 22 gradually decreases, and the centrifugal force is further enhanced. The impurities and clumps slide down the conical wall to the output end, and the preliminarily purified raw material gathers towards the center. The material after hydrocyclone separation (containing a small amount of residual waste) flows into the conveying pipe 4. The conveying pipe 4 guides the material to the filter pipe 3. At the same time, the waste is deposited to the bottom of the pipe under the action of gravity. It enters the collection tank 41 for storage through the connection structure between the conveying pipe 4 and the collection tank 41. Regular cleaning of the collection tank 41 can prevent the waste from flowing back. Open the second valve to allow the pre-purified raw material after slag removal from the conveying pipe 4 to flow into the filter pipe 3. The first mounting part 32 and the second mounting part 33 inside the filter pipe 3 fix the position of the filter element 31 to ensure that the raw material completely flows through the filter element 31. When the raw material passes through the filter element 31, fine impurities (such as micron-sized mechanical impurities) are intercepted by the filter element 31. The further purified raw material flows out from the filter pipe 3 and enters the feed end of the variable pitch screw feeder 5. If the filter element 31 becomes clogged, the second valve can be closed, the filter pipe 3 can be disassembled through the flange, and the filter element 31 can be replaced or cleaned to ensure continuous and stable filtration accuracy. When the variable pitch screw feeder 5 starts, the larger blade spacing at the feed end accommodates the raw material and avoids accumulation at the feed inlet. During the conveying process, the gradually decreasing blade spacing exerts compression and shearing forces on the raw material, breaking up slight clumps, and the raw material moves towards the discharge end in a loose state. At the same time, the control component starts temperature monitoring and regulation. The temperature sensor collects the temperature of the raw material in the feeder in real time. If the temperature is lower than the set threshold (the temperature at which clumps easily), the control component drives the heating jacket 51 to start, transferring heat to the feeder to maintain the appropriate flowability of the raw material. If the temperature reaches the threshold, the heating jacket 51 stops heating to prevent the raw material from overheating and deteriorating.

[0048] The raw material is evenly conveyed to the vibrating screen tube 6 by the variable pitch screw feeder 5. The vibration component 7 is started. The drive component 72 drives the eccentric wheel 74 to rotate through the rotating shaft 73. The eccentric wheel 74 pushes the roller 771 and the action rod 76 to rise and fall along the sleeve 75. The action rod 76 drives the vibrating screen frame 61 and the screen 62 to vibrate continuously.

[0049] After the raw material enters the vibrating screen tube 6, the screen 62 traps the remaining small lumps and impurities that have escaped the screen. The vibration makes it difficult for impurities to adhere to the surface of the screen 62, and at the same time breaks up the tiny agglomerates in the raw material. If the screen 62 becomes slightly blocked, the third valve is opened, and the backwash water tank 91 introduces backwash water into the vibrating screen tube 6 to clean the screen 62. After that, the valve is closed. At this time, the reactor 8 is in the closed state.

[0050] The purified raw materials flow into the reactor 8 through the output pipe 9. The operator opens the feed valve according to the reaction progress in the reactor 8, so that the purified raw materials flow steadily into the reactor 8 along the output pipe 9, thus completing the feeding process. During the feeding process, the flow rate into the reactor can be adjusted by the feed valve to avoid the reaction being affected by excessive or insufficient raw materials.

[0051] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
