However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a rust remover reaction preparation device, including a reaction vessel 1 and a support frame 4.

[0019] The specific settings and functions of this embodiment will be described in detail below. The support frame 4 is the core support, which undertakes the fixing and positioning of each functional component and is the key carrier for realizing the modular layout of the equipment. The support frame 4 is an open frame structure. The interior is planned with three independent installation chambers from left to right. The size of the chambers is adapted to the installation requirements of the pretreatment filter 14, the precision filter 15 and the membrane filter 16 respectively. The bottom of each chamber is equipped with horizontal adjustment feet to ensure that the filter is installed horizontally to ensure the filtration effect.

[0020] A rectangular mounting panel is reserved at the front end of the support frame 4. The first support frame 8 is welded to one end of the support frame 4. The first support frame 8 adopts a triangular stable structure design and has an arc-shaped bracket welded to the top. The inner diameter of the bracket is adapted to the outer wall of the cleaning tank 11 and is equipped with a rubber anti-slip pad to prevent the cleaning tank 11 from shaking. The second support frame 9 is fixed to the other end of the frame. The second support frame 9 is a double-layer steel plate welded structure. An annular fastener is welded to the top. The inner diameter of the annular fastener matches the outer diameter of the bottom flange of the storage tank 10. The sealing is achieved by bolts to ensure that the storage tank 10 operates stably under full load. In addition, the support frame 4 is located directly below the reactor 1. The distance between the top of the frame and the bottom of the reactor 1 is 300mm, which provides sufficient operating space for pipeline connection and maintenance.

[0021] The core of the reaction unit is the reactor 1, which is forged from 316L stainless steel. The inner wall of the reactor is coated with polytetrafluoroethylene to effectively resist the corrosion of acidic raw materials such as hydrochloric acid and oxalic acid, while avoiding direct contact between the raw materials and the metal reactor body to prevent the generation of impurities. The lower opening of the reactor 1 is sealed to the solenoid valve 6 through a graphite composite gasket. The solenoid valve 6 is made of two-position three-way corrosion-resistant stainless steel, which can accurately control the timing of the discharge of the reaction products.

[0022] The composite stirring assembly 2 is fixed to the upper center of the reactor 1 via a flange. This assembly consists of a drive motor, a planetary gearbox, a main stirring shaft, and multiple layers of stirring paddles. The drive motor is a 1.5kW three-phase asynchronous motor, and the speed is precisely controlled by a frequency converter to ensure stable operation of the stirring paddles. The main stirring shaft is made of Φ45mm 316L stainless steel and has three mechanical seals with an IP68 sealing rating to prevent leakage of the medium inside the reactor. Three layers of stirring paddles are installed on the main stirring shaft from top to bottom: the top layer is a turbine-type stirring paddle, used to quickly stir the liquid raw materials added to the top of the reactor to achieve initial mixing; the middle layer is an anchor-type stirring paddle, which can scrape off the raw material residues adhering to the reactor wall to avoid incomplete local reactions; the bottom layer is a propeller-type stirring paddle, which can push the material at the bottom of the reactor upward to circulate and eliminate the phenomenon of settling at the bottom of the reactor. A DN20 interface is reserved on the upper side of the reactor 1 to install a pressure gauge 3. The pressure gauge 3 is a shock-resistant stainless steel pressure gauge with a pressure upper limit alarm function, and transmits the signal to the control system 5.

[0023] The multi-stage filtration unit consists of a pretreatment filter 14, a precision filter 15, a membrane filter 16, and matching connecting pipes, achieving gradient removal from large particles to fine colloidal impurities. The three filters are installed sequentially in the internal chamber of the support frame 4 and connected in series through a dedicated connecting pipe. All connecting pipes are made of 316L stainless steel, seamlessly welded and passivated, with smooth inner walls and no burrs, to avoid material residue accumulation. The pretreatment filter 14 is the first line of filtration, employing a wedge-shaped filter structure with a filtration accuracy of 20μm. The filter material is 316L stainless steel, and the wedge-shaped mesh has uniform gaps, effectively intercepting unreacted solid particles (such as corrosion inhibitor agglomerates) and large particulate impurities brought in by the raw materials. The filter housing is a carbon steel lined with plastic, with the upper opening sealed to the first connecting pipe 7 via a flange. The first connecting pipe 7 has flanges at both ends that match the solenoid valve 6 and the pretreatment filter 14. The lower outlet of the pretreatment filter 14 is connected to the second connecting pipe 18 via a DN65 flange, and the other end of the second connecting pipe 18 is connected to the outer wall inlet flange of the precision filter 15.

[0024] Precision filter 15 is the second line of filtration, using a pleated polytetrafluoroethylene filter element to remove fine particles and suspended impurities from the product; the filter housing is made of 316L stainless steel, and the inlet and outlet are connected by DN65 flanges. The lower outlet is connected to the outer wall inlet of membrane filter 16 through DN50 No. 3 pipe 19. No. 3 pipe 19 is connected by a union flange for easy disassembly and maintenance.

[0025] The membrane filter 16 is the final filtration line. It is made of ceramic membrane material and can effectively intercept colloidal impurities and microorganisms to ensure product clarity. The filter housing is made of stainless steel and is equipped with a drain port and a pressure balance port. The lower opening is connected to the storage tank 10 through the connecting pipe 17. A one-way valve is installed on the connecting pipe 17 to prevent the finished product from flowing back.

[0026] The storage tank 10, which serves as a component for storing finished products, is welded from 316L stainless steel to prevent finished product residue from adhering. The inner wall of the storage tank 10 is covered with a polyurethane insulation layer, and the insulation layer is covered with a stainless steel protective shell to prevent product stratification caused by temperature changes. A first liquid level gauge 20 is installed at the upper end of the storage tank 10. This liquid level gauge is an ultrasonic liquid level gauge with real-time liquid level display and high and low liquid level alarm functions. Its signal line is directly connected to the control system 5 to realize automatic liquid level monitoring.

[0027] The intelligent control unit, with control system 5 as its core, realizes full-process automated control. Control system 5 adopts Siemens S7-200 series PLC controller, equipped with a 10-inch industrial touch screen display with a resolution of 1024×600, supports Chinese operation interface, and has built-in visual control program. The controller's input and output modules have reserved sufficient interfaces to connect with the compound stirring assembly 2, solenoid valve 6, flushing pump 13, first level gauge 20, second level gauge 26 and differential pressure sensors of each filter. The signal transmission uses shielded cable, which has strong anti-interference ability.

[0028] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first support frame 8 is fixedly installed at one end of the support frame 4, a cleaning tank 11 is installed at the upper end of the first support frame 8, an L-shaped seat 12 is installed at one end of the support frame 4, a flushing pump 13 is installed at one end of the L-shaped seat 12, a concave tube 21 is installed at the upper end of the cleaning tank 11, a flushing pipe 22 is fixedly connected to the lower end of the flushing pump 13, a first vertical pipe 23 is installed through the upper end of the pretreatment filter 14, a second vertical pipe 24 is installed through the upper end of the precision filter 15, a third vertical pipe 25 is fixedly connected to the upper opening of the membrane filter 16, a second level gauge 26 is installed at the upper end of the cleaning tank 11, the other end of the concave tube 21 is fixedly connected to the inlet of the flushing pump 13, the upper ends of the first vertical pipe 23, the second vertical pipe 24 and the third vertical pipe 25 are all fixedly connected to the outer wall opening of the flushing pipe 22, and the flushing pump 13 and the second level gauge 26 are both connected to the control system 5.

[0029] The overall effect of this embodiment is that the backwash cleaning unit is used to solve the filter clogging problem and realize online cleaning and maintenance. The core includes a cleaning tank 11, a flushing pump 13, a flushing pipe 22 and three sets of vertical pipes. All components are integrated and fixed with the support frame 4 to ensure a compact layout. The cleaning tank 11 is injection molded from food-grade polyethylene, possessing excellent acid and alkali resistance, and is used to store a mixed cleaning solution of deionized water and a special cleaning agent. The top of the cleaning tank 11 has two ports: a DN32 inlet for adding cleaning agent and deionized water; and a DN25 outlet connected to a concave tube 21 via a flange. One end of the concave tube 21 is sealed to the outlet of the cleaning tank 11, and the other end is connected to the inlet of the flushing pump 13 via a quick connector, facilitating quick disassembly and maintenance. A second level gauge 26 is also installed at the top of the cleaning tank 11. This level gauge has a float-type structure; when the cleaning solution level is below the lower limit, it immediately sends an alarm signal to the control system 5, prompting the replenishment of cleaning solution. The flushing pump 13 is fixed to one end of the support frame 4 via an L-shaped seat 12, and its horizontal section is matched and fixed with the mounting flange at the bottom of the flushing pump 13. The flushing pump 13 is a corrosion-resistant centrifugal pump with a pump body made of 316L stainless steel and an impeller made of fluoroplastic material, which can provide sufficient flushing pressure to remove impurities that clog the inside of the filter. The outlet of the flushing pump 13 is connected to the flushing pipe 22 via a flange. The flushing pipe 22 is a DN32 stainless steel main pipe, which is laid along the top crossbeam of the support frame 4 and fixed with pipe clamps to prevent the pipeline from loosening due to vibration. The outer wall of the flushing pipe 22 is evenly distributed with three DN25 branch interfaces, which are respectively connected to the first vertical pipe 23, the second vertical pipe 24 and the third vertical pipe 25 by welding. All three vertical pipes are DN25 stainless steel pipes, and their lengths are adapted to the installation height of the three filters. The lower ends of the pipes pass through the upper end caps of the corresponding filters and extend to the top of the filter elements.

[0030] The usage and working principle of this device are as follows: Raw material reaction: After pretreatment by the raw material supply unit, the liquid / solid raw materials are put into the reaction vessel 1. The composite stirring component 2 performs multi-layer stirring to achieve uniform mixing. The temperature control unit maintains the reaction temperature, and the pressure gauge 3 monitors the pressure inside the vessel to complete the rust remover reaction. Multi-stage filtration: After the reaction, the product enters the multi-stage filtration unit through solenoid valve 6 and No. 1 connector 7, and passes through pretreatment filter 14 (20μm to remove large particles), precision filter 15 (1μm to remove fine particles), and membrane filter 16 (0.22μm to remove colloids) in sequence. After filtration, it is sent to storage tank 10 through connecting pipe 17. Online cleaning: The control system 5 monitors the filter pressure difference in real time. When it exceeds 0.1MPa, backwashing is started: the flushing pump 13 draws the cleaning liquid from the cleaning tank 11 and flushes the filter element in reverse through the flushing pipe 22 and the corresponding vertical pipe. Impurities are discharged from the drain port. Dual-path switching ensures continuous production. Intelligent control: The control system 5 coordinates the stirring, filtration, and backwashing processes, while the first / second level gauges monitor the liquid levels in the storage tank / cleaning tank 11, achieving full-process automation and safety early warning.
