Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection technology, and particularly to a filtration system, and more particularly to an intelligent backwashing filtration system. Background Art

[0002] The sources of electroplating wastewater generally include: (1) rinsing water for electroplated parts; (2) waste electroplating solution; (3) other wastewater, including floor flushing water in the workshop, electrode plate scrubbing water, condensate water from ventilation equipment, and various bath solutions and drainages caused by "running, overflowing, dripping, and leaking" due to tank leakage or improper operation and management; (4) equipment cooling water, which is not polluted except for temperature rise during use. The water quality and quantity of electroplating wastewater are related to factors such as electroplating production process conditions, production load, operation management, and water use methods. The water quality of electroplating wastewater is complex and its components are not easy to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, and silver, as well as cyanide, etc., and some are highly toxic substances that are carcinogenic, teratogenic, and mutagenic. From the electroplating production process, electroplating wastewater can be divided into four categories: post-treatment wastewater, waste plating solution, and waste stripping solution. Electroplating wastewater treatment refers to electroplating rinsing wastewater, passivation wastewater, electroplating pickling wastewater, floor and electrode plate cleaning wastewater, wastewater caused by improper operation and management, as well as the discharge of self-used water and the discharge from the inspection room during wastewater treatment. There are mainly two ways for electroplating wastewater to pollute the environment. One is to discharge a small amount of high-concentration electroplating wastewater, and the other is to discharge a large amount of relatively low-concentration electroplating wastewater (mainly cleaning wastewater). The treatment of electroplating wastewater incurs production costs, and the costs of electroplating wastewater treatment mainly come from: 1. Electricity consumption for the operation of electroplating wastewater treatment equipment; 2. Chemical costs required for the operation of electroplating wastewater treatment equipment, such as caustic soda or lime, packaging, polyacrylamide, etc.; 3. Solid waste treatment costs generated by electroplating wastewater treatment, such as dewatered sludge, evaporated miscellaneous salts, etc.; 4. Depreciation of electroplating wastewater treatment equipment; and 5. Labor costs.

[0003] The filtration of electroplating solution requires passing through the filter element of a filter press. The prior art (CN213835606U) discloses an electroplating filter press that facilitates the replacement of the filter element, including an electroplating filter press body, a filter element, a cleaning plate, a motor, and a cylinder. At the four corner positions at the bottom of the electroplating filter press body, there are installed bases. Inside the electroplating filter press body, there are empty slots, and inside the empty slots, there is a cylinder. The output end of the cylinder is provided with a mounting cover, and at the top of the mounting cover, there is a feed port that penetrates the mounting cover. At the top of the mounting cover, there is a support guide rail, and inside the support guide rail, there is a slider. Inside the support guide rail, there are cross slots. For this electroplating filter press that facilitates the replacement of the filter element, by starting the cylinder to drive the mounting cover to move upward, the mounting cover drives the support guide rail to move upward, which facilitates the operator to replace the filter element inside the slider without draining the electroplating solution inside the electroplating filter press body. This structure is simple to operate and convenient to use. However, although it is easy to replace the filter element, the filter element is one of the usage costs of the electroplating filter press.

[0004] In order to save the cost of replacing the filter element, another prior art (CN115382304A) discloses a cleaning method for the filter element of an electroplating filter press, including: S1. Soaking the used filter element in an acid pickling solution; S2. Soaking the filter element in tap water and rinsing; S3. Connecting the filter element to a cleaning tooling and connecting it to a tap water pipe; S4. Opening the tap water pipe to rinse the filter element, and a booster pump can be used to increase the water pressure if necessary; S5. Separating the cleaning tooling from the tap water pipe and putting it into an ultrasonic cleaning machine for cleaning; S6. Connecting the cleaning tooling to the tap water pipe for secondary cleaning; S7. Connecting the cleaning tooling to compressed air to blow dry. The present invention dissolves the deposits on the surface of the filter element in advance according to the usage environment of the electroplating filter element, which is beneficial for subsequent cleaning. At the same time, according to the shape characteristics of the filter element, a cleaning tooling is designed, which is convenient for installation and use, realizes the cleaning and reuse of waste filter elements, and can clean multiple filter elements at one time, with simple operation and low cost. However, by cleaning to achieve the recycling of the filter element, although the cost of replacing the filter element can be reduced, it cannot ensure excellent filtering effect.

[0005] During the process of implementing the technical solutions in the prior art, the applicant found that there are still the following technical problems in the technical solutions of the prior art:

[0006] Since the components of different electroplating solutions are different, in the same filtration system, using a one-size-fits-all filtration process cannot meet the filtration requirements. Using the filter element replacement time in the machine operation manual will also lead to unnecessary replacement frequencies or failure to replace in a timely manner when replacement is needed because the maintenance cycle in the maintenance manual is blindly followed. Eventually, it leads to an increase in production costs (an increase in the cost of electroplating solution filtration) and poor filtration effects. Summary of the Invention

[0033] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] In the past, the electroplating industry specifications have not been fully formed, and the requirements for sewage discharge are relatively simple. There are situations where unqualified wastewater is discharged, and there are also situations where electroplating wastewater is diluted with a large amount of water. With the increasingly strict industry specifications and the improvement of relevant regulations, strict penalties will be imposed on the former (the situation of discharging unqualified wastewater).

[0035] For the latter approach, although diluting electroplating wastewater with a large amount of water flushing can meet the requirements of industry standards and laws and regulations. However, on the one hand, this method is prone to cause waste of water resources and increase the production cost.

[0036] In order to avoid a large amount of water waste, various electroplating wastewater filters have emerged on the market. However, the electroplating wastewater filter needs to often replace the filter element, resulting in an increase in production cost. In addition, the one-size-fits-all or very few filtration processes of the filter cannot meet the filtration requirements in various situations.

[0037] The technical solution of the embodiment of the present application provides an intelligent backwashing filtration system, which solves the problems of high filtration cost and insufficient filtration effect in the prior art, and realizes the beneficial effects of reducing the filtration cost and improving the filtration efficiency at the supply end of the liquid to be filtered, the filtration treatment main body end, the recovered end of the filtered liquid, the sensing system combined with the central control end, and the database.

[0038] The general idea of the implementation scheme of the present invention to solve the above technical problems is as follows:

[0039] An intelligent backwashing filtration system consists of a supply end for the liquid to be filtered, a main body end for filtration processing, a recovery end for the filtered liquid, a sensing system, a central control end, and a database. The supply end for the liquid to be filtered includes an electroplating device or a group of electroplating devices, and the main body end for filtration processing is connected to the supply end for the liquid to be filtered. Additionally, the recovery end for the filtered liquid is connected to the main body end for filtration processing, and the recovery end for the filtered liquid is at least one recovery tank or cleaning tank. Moreover, multiple sensors are provided in the sensing system and distributed at the supply end for the liquid to be filtered, the main body end for filtration processing, and the recovery end for the filtered liquid. The central control end is electrically and data-connected to the supply end for the liquid to be filtered, the main body end for filtration processing, the recovery end for the filtered liquid, and the sensing system. The central control end is also electrically and data-connected to the control panel. The database stores preset filtration processes and is data-connected to the central control end and the sensing system. The database also has a series of technical means such as an information input port. This enables the selection of a preset filtration process through the control panel or the matching of the data detected by the sensing system for the liquid supply end with the optimal preset filtration process in the database, and the central control end starts or starts the operation process of the main body end for filtration processing with one key. In addition, based on the collected data, a better filtration process can be summarized or optimized manually, and anomalies can be detected in a timely manner according to the data and the trend of the data.

[0040] Specifically, according to the liquid to be filtered from the electroplating equipment to be filtered, the most suitable filtration parameters can be determined, and while ensuring that the filtered wastewater discharged meets the standards, a considerable amount of recoverable electroplating solution can be recycled and reused for electroplating operations. Thus, the cost and filtration efficiency are optimized.

[0041] To better understand the above technical solution, the above technical solution will be described in detail below in combination with the accompanying drawings of the specification and specific implementation manners.

[0042] An intelligent backwashing filtration system is composed of the following components combined:

[0043] A supply end for the liquid to be filtered, including an electroplating device or a group of electroplating devices;

[0044] A main body end for filtration processing, and the main body end for filtration processing is connected to the supply end for the liquid to be filtered;

[0045] A recovery end for the filtered liquid, and the recovery end for the filtered liquid is connected to the main body end for filtration processing. The recovery end for the filtered liquid is at least one recovery tank or cleaning tank;

[0046] A sensing system, and multiple sensors are provided in the sensing system and distributed at the supply end for the liquid to be filtered, the main body end for filtration processing, and the recovery end for the filtered liquid;

[0047] A central control end, and the central control end is electrically and data-connected to the supply end for the liquid to be filtered, the main body end for filtration processing, the recovery end for the filtered liquid, and the sensing system. The central control end is also electrically and data-connected to the control panel;

[0048] A database that stores a preset filtration process and is connected to the central control terminal and the sensing system for data; the database is also provided with an information input port;

[0049] Among them, the preset filtration process is selected through the control panel or the data detected by the sensing system for the liquid supply end is matched with the optimal preset filtration process in the database, and the operation process of the filtration processing main body end is started by the central control terminal. This enables the operation process to be adjusted according to different application scenarios.

[0050] The overall structure of the filtration processing main body end of the intelligent backwashing filtration system can be referred to Figure 1 and the interface of the control panel can be referred to Figure 2 .

[0051] The preset filtration process includes the forward flow of the liquid to be filtered through the flow channels and filtration devices of the filtration processing main body end, as well as the backwashing process; the preset filtration process is started according to the operation process.

[0052] Specifically, the parameters sensed by the sensing system are automatically stored in the database. As the database data becomes richer, operators can continuously optimize the filtration process with the best energy efficiency ratio or economic benefits through data analysis.

[0053] During the operation of the equipment, it is inevitable to have failures or local abnormalities. In order to give timely feedback when abnormalities occur, the intelligent backwashing filtration system also includes an early warning module connected to the central control terminal for data, which gives an alarm for preset abnormal scenarios.

[0054] Among them, the preset abnormal scenarios include high-pressure alarm, low-pressure alarm, and abnormal electrical parameter alarm. The early warning module is also provided with an alarm record function to record the alarm time and fault code.

[0055] In one implementation, as Figure 4 shown, the filtration processing main body end of the intelligent backwashing filtration system includes a primary pretreatment collection filtration system, a secondary electronic ultrafiltration membrane system, and a tertiary electronic migration membrane system.

[0056] Specifically:

[0057] The primary pretreatment collection filtration system

[0058] The electroplating secondary and tertiary wastewater is pretreated by a pretreatment system (the filter barrel contains a PP filter element) to remove most of the solid suspended matter, large and small molecular colloids, medium and small particles, etc., so as to prevent and delay the deposition of pollutants on the electronic migration membrane to the greatest extent, prevent the blockage of colloidal substances and solid suspended matter particles, and prevent the damage of substances such as organic matter, microorganisms, and oxides to the membrane, so as to delay the service life of the membrane, so that the membrane system can work in a good state.

[0059] Secondary electronic ultrafiltration membrane system

[0060] After passing through the pretreatment system, the wastewater is sent by a delivery pump to the secondary electronic ultrafiltration membrane system for continuous fine filtration. The finely filtered wastewater directly enters the tertiary electron migration membrane system, and most of the molecular impurities are intercepted by the membrane and returned to the pretreatment system.

[0061] Three-stage electron transport membrane system

[0062] After the wastewater is treated by the secondary electronic ultrafiltration membrane system, it is sent to the tertiary electronic migration membrane system by the delivery pump for circulation and concentration. After the treatment of this system, 99% of organic matter and heavy metals are intercepted, and the effluent water quality can meet the requirements of cleaning water quality.

[0063] In one embodiment, the filtering treatment main body of the intelligent backwashing filtering system is composed of a positive pressure module and a negative pressure module, a carbon canister and a medicine canister; the bottoms of the positive pressure module and the negative pressure module are connected to a sewage pipe, and the carbon canister and the medicine canister are connected to the positive pressure module and the negative pressure module respectively. The bottoms of the positive pressure module and the negative pressure module are connected to a fluid pump and an air pipe respectively.

[0064] like Figure 3 As shown, the supply end of the liquid to be filtered includes a plating tank, and the filtered liquid recovery end includes a recovery tank. In addition, it also includes multiple cleaning tanks.

[0065] After the electroplating wastewater enters the online precision filter through the cleaning tank (two) for filtration treatment, the filtrate obtained is divided into two parts. 70% of the pure water returns to the cleaning tank (three), and its effluent water quality can meet the cleaning water requirements, and 30% of the concentrated water returns to the cleaning tank (one) for replacement discharge.

[0066] The desired advantageous features of one embodiment of the present invention are:

[0067] 1. Save labor: After one-button start, the equipment will run automatically, and will automatically stop for cleaning when the set time or pressure is reached. The cleaning time is 15-25 minutes, and it will automatically start running after cleaning. There is no filter element replacement cost within 3-10 years, which greatly saves labor costs.

[0068] 2. Save water and electricity: Quantitative water intake without waste, about 70 liters of water are used for each cleaning; the system filter element does not need to be disassembled, cleaned or replaced, and the water consumption is very small, which greatly saves the cost of sewage treatment and avoids the impact of human installation errors on the filtering effect, while also saving electricity bills.

[0069] 3. Save consumables: The intelligent filter cleans the filter element by repeated flushing, which will never damage the filter element. Under normal circumstances, the service life of the filter material is about 3-10 years, and there is no hazardous solid waste treatment cost; the same energy consumption brings higher filtration efficiency. One large intelligent machine replaces multiple (depending on the owner's production needs) traditional filters, which reduces energy consumption costs in disguise.

[0070] 4. Excellent cleaning effect: membrane filtration, using 1μm absolute filtration pore size, double-sided filtration, single-group cleaning, dirt falls directly to the bottom of the barrel for removal, cleaning is thorough and no residue, with good filtering effect, more environmentally friendly.

[0071] In addition, through the Industrial Internet of Things, the embodiments of the present invention also have the following advantages and features:

[0072] It starts with one button, runs automatically, and automatically stores data for traceability. It integrates host control and PC terminal. The display screen shows flow rate, pH value, temperature, cumulative water volume for cleaning the filter, and cumulative electricity consumption. It only takes 3-5 minutes to activate the carbon, which can be cleaned quickly without leaking carbon powder into the tank.

[0073] Among them, the early warning function of the implementation mode of the present invention includes:

[0074] 1. The high-voltage alarm function prevents the equipment from doing useless work and can prevent safety accidents;

[0075] 2. The low pressure alarm function can effectively prevent the pump from leaking due to water shortage;

[0076] 3. Abnormal alarm function: alarm will be given if the motor current is too high or phase is missing;

[0077] 4. The alarm record function records the detailed alarm time and fault code.

[0078] Alarm mode: local touch screen alarm, fault analysis: local fault alarm analysis, water shortage protection alarm.

[0079] The cost advantages of one embodiment of the present invention are as follows:

[0080] 1. Cost of main filter materials:

[0081] --Traditional filter:

[0082] Traditional filter elements, filter cloths or filter papers need to be discarded after use in the functional electroplating (such as PCB, plumbing) industry. The replacement cycle of filter consumables is 1-2 weeks. Taking the cotton core as an example, if it is replaced every 10 days on average, and 18 30-inch cotton cores are replaced at a price of 15 yuan each, the annual replacement cost is nearly 10,000 yuan (9,720 yuan).

[0083] --Implementation methods of the present invention:

[0084] The service life cycle is 3-10 years. There is no need to replace the filter element. Through cleaning and maintenance, taking filtering nickel sulfate plating solution as an example, the cleaning cost is 20 yuan per month, and only 240 yuan per year. This cost is about 1 / 50 of that of traditional machines.

[0085] 2. Manual operation cost:

[0086] --Traditional filter:

[0087] Periodically disassemble and clean the filter element manually. Generally, it is cleaned once per shift, and the annual cost is 4,500 yuan. And it requires shutdown operation.

[0088] -- Embodiment of the present invention:

[0089] There is no need to shut down for cleaning the filter element, and there is no labor cost in this regard.

[0090] 3. Sewage discharge:

[0091] -- Traditional filter press:

[0092] Manually centralized cleaning generates a large amount of sewage and wastes water resources. The designed water consumption for each cleaning is about 200 liters. The annual water consumption cost is 3,600 yuan.

[0093] -- Embodiment of the present invention:

[0094] The filter element is cleaned in a closed manner, automatically, saving energy and reducing emissions. Only 50 liters of water is consumed each time. It has an independent sewage discharge pipeline and is cleaned once a week. The sewage discharge fee per ton is only 30 yuan, and the annual cost is 72 yuan. The water consumption and sewage treatment fee are reduced by more than 3,500 yuan.

[0095] 4. Treatment of solid hazardous waste:

[0096] -- Traditional filter press:

[0097] Periodically discard the filter element which belongs to hazardous solid waste and pay the solid waste treatment cost. The annual cost is 648 yuan.

[0098] -- Embodiment of the present invention:

[0099] There is no solid hazardous waste, and the cost is zero.

[0100] 5. Consumption of bath solution:

[0101] -- Traditional filter press:

[0102] When replacing the filter element, 500 grams of bath solution is taken out each time. The bath solution is 5 yuan per kilogram, and there are about 18 filter elements in each machine. The annual cost is 27,000 yuan.

[0103] -- Embodiment of the present invention:

[0104] The surface of the special PVDF material is smooth, and water is not easy to stay, so basically no bath solution is taken out.

[0105] 6. Man-hour:

[0106] -- Traditional filter press:

[0107] Periodically disassemble and clean, and the annual cleaning man-hour is 450 hours.

[0108] -- Embodiment of the present invention:

[0109] Automatically sealed and cleaned, without involving man-hours and without delaying production.

[0110] 7. Annual consumption cost:

[0111] -- Traditional filter press:

[0112] 45,468 yuan.

[0113] -- Embodiment of the present invention:

[0114] 312 yuan. Saving more than 45,000 yuan.

[0115] The above embodiments are inseparable from various cubic container tanks such as plating tanks, recovery tanks, and cleaning tanks. The preparation process of the cubic container tank is to cut out 4 squares at the four corners of the rectangular sheet and then bend and process it into a cubic container tank. To save the overall production cost, it is also necessary to save materials inside each cubic container tank. For example, when cutting out 4 squares with a side length of x at the four corners of a sheet with a side length of l, when each parameter satisfies the formula l 2 - 4lx + 3x 2 = 0, the sheet can be used to prepare a cubic container tank with the maximum capacity.

[0116] The advantages of the embodiments of the present invention are also corroborated by the test results of the filtered samples:
