[0002] With the continuous improvement of industrial production and environmental protection requirements, filtration technology has been widely used and rapidly developed in various fields. Advanced filtration technology can not only efficiently remove impurities, particles and microorganisms in liquids, but also emphasize energy efficiency and automation level. In the future, filtration technology will develop in the direction of intelligence, greenness and multifunctionality to meet the higher demands of different industries for filtration accuracy and efficiency.

[0003] Most of the current filtration devices use a single filtration method, such as mechanical filtration, activated carbon adsorption or membrane filtration. These devices are relatively simple in structure and single in function. They usually lack the ability to fully pre-treat liquids. Some equipment may have basic temperature control or detection functions, but they often cannot achieve full-process automation, and cleaning and maintenance are also inconvenient. In addition, when processing complex liquids, existing filtration devices may have problems such as low filtration efficiency and unstable filtration quality.

[0004] Although the prior art has been optimized in many aspects, it lacks multi-stage filtration, automatic cleaning, temperature control and detection functions. In addition, the prior art has problems such as low filtration efficiency, unstable quality, and difficult maintenance, resulting in low filtration efficiency and quality, and a short service life of the equipment. Therefore, technical personnel in this field provide a filtration device for acidic etching waste liquid. Summary of the invention

[0005] The object of the present invention is to provide a filtering device for acidic etching waste liquid to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The filtering device includes a pretreatment mechanism, a filtering mechanism, a cleaning mechanism, a box, a temperature control mechanism and a detection mechanism. The pretreatment mechanism and the box are tightly connected, the pretreatment mechanism is located above the filtering mechanism, the filtering mechanism and the box are tightly connected, the filtering mechanism and the pretreatment mechanism are communicated, so the cleaning mechanism and the box are tightly connected, the cleaning mechanism and the filtering mechanism are communicated, the cleaning mechanism and the pretreatment mechanism are communicated, the temperature control mechanism and the box are tightly connected, the detection mechanism and the box are tightly connected, and the detection mechanism and the filtering mechanism are communicated.

[0008] By adopting the above technical scheme, the pretreatment mechanism is fixedly connected to the top of the box body and is located above the filtering mechanism. The pretreated liquid enters the filtering mechanism through the connected filtering mechanism. The filtering mechanism is also fixedly connected to the box body, forming a close upper and lower connection with the pretreatment mechanism. The cleaning mechanism is fixedly connected to the box body and is connected with the filtering mechanism and the pretreatment mechanism at the same time, so that both can be effectively cleaned and maintained. The temperature control mechanism is fixedly connected to the box body and is used to adjust the temperature inside the device to ensure that the filtering process is carried out under the best conditions. The detection mechanism is fixedly connected to the box body and is connected with the filtering mechanism to monitor the quality of the filtered liquid. The liquid to be treated first enters the pretreatment mechanism, undergoes pretreatment processes such as homogenization, neutralization, flocculation and precipitation, removes most of the impurities, and prepares for subsequent filtration. The pretreated liquid enters the filtering mechanism through the connected filtering mechanism and is filtered. For further fine filtration, the filtered liquid is quality monitored by the detection mechanism to ensure that it meets the predetermined filtration standards. The cleaning mechanism can clean the pretreatment mechanism and the filtration mechanism as needed to prevent blockage and ensure the continuous and stable operation of the equipment. The pretreatment mechanism is used to perform preliminary treatment on the liquid to reduce the filtration load, and then the remaining impurities are removed through multi-stage filtration of the filtration mechanism. The temperature control mechanism ensures that the temperature of the filtration environment is appropriate to improve the filtration efficiency. The detection mechanism provides real-time feedback on the filtration effect to facilitate the adjustment of filtration parameters. The cleaning mechanism regularly cleans key components to maintain equipment performance. The pretreatment mechanism improves the filtration efficiency, the filtration mechanism ensures the filtration quality, the cleaning mechanism maintains the operating status of the equipment, the temperature control mechanism optimizes the working conditions, and the detection mechanism ensures the filtration effect, achieving the effect of improving filtration efficiency, ensuring filtration quality and extending equipment life.

[0009] Furthermore, the pretreatment mechanism includes a homogenization component, a neutralization component and a flocculation and sedimentation component.

[0010] By adopting the above technical solution, the liquid to be treated first enters the homogenization component, the homogenization component fully mixes the liquid to make its composition uniform, and then sends the liquid to the neutralization component through the connecting pipe with the neutralization component; in the neutralization component, the pH of the liquid is adjusted to an ideal range, and the neutralized liquid then enters the flocculation and sedimentation component through the connecting pipe, in the flocculation and sedimentation component, flocculant is added to make the suspended particles aggregate to form flocs, and solid impurities are separated by precipitation; the clear liquid after precipitation enters the filtering mechanism through the connecting part of the flocculation and sedimentation component and the filtering mechanism for further filtration, and the flocculation and sedimentation component is also connected with the cleaning mechanism to facilitate regular cleaning of sediments. To prevent clogging, the homogenization component fully mixes to ensure uniform distribution of various components in the liquid and improve the effect of neutralization and flocculation. The neutralization component adjusts the pH value of the liquid to provide optimal conditions for the flocculation process. The flocculation and sedimentation component uses flocculants to make tiny suspended particles form larger flocs, which is convenient for sedimentation and separation. The close connection and connectivity of each component ensures the continuity and efficiency of the liquid treatment process. The homogenization component improves the liquid mixing efficiency, the neutralization component ensures the appropriate pH of the liquid, and the flocculation and sedimentation component effectively removes suspended impurities. It is also connected with the cleaning mechanism to facilitate equipment maintenance and cleaning, ultimately achieving the effect of improving filtration efficiency and filtration quality.

[0011] Furthermore, the homogenization assembly includes a homogenizing motor, a homogenizing blade, a homogenizing scraper, an angle motor, a homogenizing box, a homogenizing rod, a nozzle, a discharge valve and a cleaning valve. The homogenizing box is fastened to the box body, the homogenizing motor is fastened to the homogenizing box, the homogenizing motor is transmission-connected to the homogenizing rod, the homogenizing blade is rotationally connected to the homogenizing rod, the homogenizing scraper is hinged to the homogenizing rod, the angle motor is fastened to the homogenizing rod, the angle motor is transmission-connected to the homogenizing scraper, there are four homogenizing scrapers, and the angles of the two homogenizing scrapers on both sides are centrally symmetrical.

[0012] By adopting the above technical scheme, the homogenizing box is firmly connected to the box body, which serves as the main container for homogenization treatment. The homogenizing motor is fixedly connected to the homogenizing box, and is connected to the homogenizing rod through a transmission gear set to drive the homogenizing rod to rotate. The homogenizing blade is rotatably installed on the homogenizing rod. As the homogenizing rod rotates, the liquid is fully stirred to achieve homogenization. The homogenizing scraper is hingedly connected to the homogenizing rod. The angle motor is fixedly connected to the homogenizing rod and is connected to the homogenizing scraper through a gear or a connecting rod mechanism. The angle of the scraper is adjusted to make it close to the inner wall of the homogenizing box. There are four homogenizing scrapers in total. The angles of the two scrapers on both sides are symmetrically set, and the angles of the two scrapers at the bottom are also symmetrically set to ensure comprehensive scraping of the inner wall of the container. The nozzle is fixedly connected to the homogenizing rod and is connected to the internal channel of the homogenizing rod. The nozzle is connected to the cleaning mechanism through the homogenizing rod, and the cleaning liquid can be sprayed during the cleaning process. The discharge valve is fixedly connected to the lower part of the homogenizing box, connected to the homogenizing box, and connected to the neutralizing component to discharge the homogenized liquid to the neutralizing component. The cleaning valve is also fixedly connected to the homogenizing box, connected to the homogenizing box and the cleaning mechanism, which is convenient for cleaning the residue. A discharge surface is provided at the lower end of the homogenizing box. The cross-section of the discharge surface is a trapezoidal annular surface, which is conducive to the smooth discharge of liquid and residue and reduces retention. The homogenizing motor is started, driving the homogenizing rod to rotate, and the homogenizing blades rotate accordingly, stirring the liquid entering the homogenizing box at a high speed to make its composition uniform. The angle motor adjusts the angle of the homogenizing scraper through the transmission mechanism so that the scraper is close to the inner wall of the homogenizing box. When the homogenizing rod rotates, the scraper scrapes the inner wall to prevent the material from adhering to the inner wall. When cleaning is needed, the cleaning mechanism supplies cleaning liquid to the nozzle through the channel in the homogenizing rod. The nozzle sprays the cleaning liquid to flush the inside of the homogenizing box. After stirring is completed, the discharge valve is opened, and the liquid flows smoothly into the neutralization component through the discharge surface. The cleaning valve can be opened during the cleaning process to discharge the cleaning waste liquid. The synergistic effect of mechanical stirring and the scraper is utilized to achieve liquid homogenization and cleaning of the inner wall of the container. The homogenizing motor drives the homogenizing rod to rotate through the transmission gear set, and the homogenizing blades enhance the stirring effect. The angle motor drives the homogenizing scraper to adjust the angle through the gear transmission or the connecting rod mechanism, so that it can effectively scrape off the inner wall attachments during rotation. The nozzle is connected to the cleaning mechanism through the internal channel to facilitate the cleaning operation. Through the above design, the homogenization component can efficiently homogenize the liquid, prevent the material from adhering to the inner wall of the container, and improve the stirring efficiency and homogenization effect; at the same time, the convenient cleaning function ensures the hygiene of the equipment and the quality of subsequent processing.

The pH sensor is fixedly connected to the neutralization box to monitor the pH value of the liquid in the neutralization box in real time. The neutralization motor is fixed on the neutralization box and is connected to the neutralization worm through the transmission shaft to drive the neutralization worm to rotate. The neutralization worm is provided with a spiral guide hole, and the spiral direction of the guide hole is opposite to the spiral direction of the neutralization worm. This design can enhance the turbulence effect of the liquid and promote mixing when the worm rotates. The connecting pump is connected to the neutralization tank and also to the flocculation and sedimentation component to transport the neutralized liquid to the next treatment stage; the liquid to be treated enters the neutralization tank, the metering pump draws an appropriate amount of neutralizer from the regulating tank and injects it into the neutralization tank, the neutralization motor starts, and drives the neutralization worm to rotate. Since the spiral direction of the guide hole on the neutralization worm is opposite to the rotation direction of the worm, the liquid is sheared and reversely thrust when the worm rotates, forming a strong turbulence, which enhances the mixing effect of the neutralizer and the liquid. The pH sensor detects the pH in the neutralization tank in real time and feeds the data back to the control system to adjust the delivery volume of the metering pump to ensure that the pH value of the liquid reaches the preset range. The neutralized liquid passes through the connecting pump. The liquid is pumped to the flocculation and sedimentation component for subsequent treatment. The rotation of the neutralization worm and the specially designed guide hole generate strong liquid disturbance to enhance the mixing efficiency of the neutralizer and the liquid. The reverse spiral design of the guide hole causes the liquid to receive additional reverse thrust when the worm rotates, forming a more complex flow path and further improving the mixing effect. The real-time monitoring of the pH sensor and the precise control of the metering pump make the neutralization process more accurate and controllable. Through the above design, the neutralization component realizes efficient neutralization treatment of the liquid, ensures that the pH value of the liquid reaches an ideal state, provides good conditions for the subsequent flocculation and sedimentation process, and improves the treatment efficiency and filtration quality of the entire filtration device.

When the homogenizing rod 116 rotates, the scraper scrapes the inner wall to prevent the material from adhering to the inner wall.

[0047] By adopting the above technical solution, the metering pump 124 is fixedly installed on the neutralization box 122, and is connected to the neutralization box 122 and the regulating box 121, and is used to accurately transport the neutralizer in the regulating box 121 to the neutralization box 122.

The neutralization motor 126 is fixed on the neutralization box 122, and is connected to the neutralization worm 125 through the transmission shaft to drive the neutralization worm 125 to rotate. The neutralization worm 125 is provided with a spiral guide hole 1251, and the spiral direction of the guide hole 1251 is opposite to the spiral direction of the neutralization worm 125.

The neutralization motor 126 is started to drive the neutralization worm 125 to rotate. Since the spiral direction of the guide hole 1251 on the neutralization worm 125 is opposite to the rotation direction of the worm, the liquid is sheared and reversely thrusted when the worm rotates, forming a strong turbulence, which enhances the mixing effect of the neutralizer and the liquid. The pH sensor detects the pH value in the neutralization box 122 in real time, and feeds back the data to the control system to adjust the delivery volume of the metering pump 124 to ensure that the pH value of the liquid reaches the preset range, and the process is completed. The neutralized liquid is transported to the flocculation and sedimentation component 13 through the connecting pump 127 for subsequent treatment. The rotation of the neutralization worm 125 and the specially designed guide hole 1251 are used to generate strong liquid disturbance and enhance the mixing efficiency of the neutralizer and the liquid. The reverse spiral design of the guide hole 1251 causes the liquid to receive additional reverse thrust when the worm rotates, forming a more complex flow path and further improving the mixing effect. The real-time monitoring of the pH sensor and the precise control of the metering pump 124 make the neutralization process more accurate and controllable. Through the above design, the neutralization component 12 realizes efficient neutralization treatment of the liquid, ensures that the pH value of the liquid reaches an ideal state, provides good conditions for the subsequent flocculation and sedimentation process, and improves the processing efficiency and filtration quality of the entire filtration device.
