Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically to an energy-saving intelligent filtration system for purifying electroplating chemicals. Background Technology

[0002] Currently, electroplating chemical tanks require a filtration unit during production to remove oil and grease. However, after a period of operation, oil accumulates and clogs the filtration unit, causing increased internal pressure and preventing proper filtration. This necessitates manual disassembly and cleaning of the filter cartridges before reinstallation. However, manual cleaning is time-consuming, labor-intensive, inefficient, and consumes a large amount of water, requiring replacement of the degreasing tank water on average every fifteen days, making it neither energy-efficient nor environmentally friendly. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this invention provides an energy-saving intelligent filtration system for purifying electroplating chemicals, employing the following technical solution:

[0004] An energy-saving intelligent filtration system for purifying electroplating chemicals includes:

[0005] The filter unit is equipped with a filter inlet, a filter outlet, a drain outlet, and a pressure sensor;

[0006] The oil removal tank is equipped with an oil removal tank inlet pipe and an oil removal tank outlet pipe. The oil removal tank inlet pipe is connected to the filter inlet and is equipped with a first solenoid valve assembly. The oil removal tank outlet pipe is connected to the filter outlet and is equipped with a second solenoid valve assembly.

[0007] A clear water tank is provided with a clear water tank inlet pipe and a clear water tank outlet pipe. The clear water tank inlet pipe is connected to the filter inlet and is equipped with a solenoid valve group seven. The clear water tank outlet pipe is connected to the filter outlet and is equipped with a solenoid valve group eight.

[0008] A cleaning solution tank has a dosing pipe at its bottom that connects to the filter inlet. The dosing pipe contains a solenoid valve group six. A cleaning pipe connects the filter outlet to the top of the cleaning solution tank. The cleaning pipe contains a solenoid valve group three. A tee connects to the drain outlet. One port of the tee connects to a solenoid valve group five, and the other port connects to a return pipe that connects to the top of the cleaning solution tank. The return pipe contains a solenoid valve group four.

[0009] A dosing tank is connected to the top of the cleaning solution tank by a delivery pipe, and a delivery pump is installed in the delivery pipe.

[0010] Furthermore, the filter unit is provided with an exhaust port at the top, and the exhaust port is equipped with the pressure sensor and the electrically controlled exhaust valve.

[0011] Furthermore, the inlet pipe of the oil removal tank is located below the outlet pipe of the oil removal tank.

[0012] Furthermore, the water inlet pipe of the clear water tank is located below the water outlet pipe of the clear water tank.

[0013] Furthermore, the top of the cleaning solution tank is an open structure, and the delivery pump is a hydraulic pump.

[0014] Furthermore, it also includes a controller, and the filter unit, the pressure sensor, the first solenoid valve group, the second solenoid valve group, the seventh solenoid valve group, the eighth solenoid valve group, the sixth solenoid valve group, the third solenoid valve group, the fifth solenoid valve group, the fourth solenoid valve group, and the electrically controlled exhaust valve are all electrically connected to the controller.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] The energy-saving electroplating chemical purification intelligent filtration system of this invention uses a controller to uniformly control the opening and closing of each solenoid valve group. By opening solenoid valve group one and solenoid valve group two and closing other solenoid valves, the liquid in the degreasing tank can be circulated and purified. By adding cleaning solution to the cleaning chemical tank through the dosing tank, and then opening solenoid valve group six and solenoid valve group four and closing other solenoid valves, the inner wall of the filter unit's main body box and the external system of the filter element can be cleaned. By opening solenoid valve group six and solenoid valve group three and closing other solenoid valves, the internal piping system of the filter element can be cleaned. By opening solenoid valve group seven and solenoid valve group eight and closing other solenoid valves, the filter unit can be circulated and cleaned using the liquid in the clean water tank.

[0017] (1) The intelligent filtration system of the present invention monitors the pressure inside the filter unit in real time through a pressure sensor, intelligently judges whether oil blockage occurs inside the filter unit, and controls the opening and closing of each solenoid valve group in an orderly manner through a controller, thereby realizing automatic cleaning of oil in the filter unit; compared with manual disassembly and cleaning, it saves maintenance time, increases the normal working time of the filtration system, and improves the working efficiency by three times, which can meet the needs of uninterrupted and continuous production of large-scale electroplating processes in factories, and greatly improves production capacity.

[0018] (2) The intelligent filtration system of the present invention has multiple solenoid valve groups controlled by the controller, the pipeline layout is scientific and reasonable, the number of parts to be disassembled manually is reduced, the safety performance is improved, the integration degree is high, the size is reduced, and it is beneficial to factory installation and maintenance.

[0019] (3) The cleaning and purification process of the intelligent filtration system of the present invention is fully automated by the controller. The dosage of the added medicine is automatically controlled, which saves production costs and is environmentally friendly and energy-saving. The staff does not have to come into contact with irritating medicine, which is more beneficial to the health of the staff. Attached Figure Description

However, the invention can be practiced in many other ways than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Example 1

[0025] like Figure 1-2 As shown, an energy-saving intelligent filtration system for purifying electroplating chemicals includes the following components:

[0026] The filter unit 1 is equipped with a filter inlet, a filter outlet, a drain outlet, and an exhaust port. The exhaust port is located at the top of the filter unit 1 and is connected to a pressure sensor 2 and an electrically controlled exhaust valve 3 via a T-junction. The pressure sensor 2 is used to detect the pressure inside the filter unit 1, and the electrically controlled exhaust valve 3 is used to release pressure.

[0027] The degreasing tank 4 is equipped with a degreasing tank inlet pipe 6 and a degreasing tank outlet pipe 7. The degreasing tank inlet pipe 6 is located below the degreasing tank outlet pipe 7. The degreasing tank inlet pipe 6 is connected to the filter inlet and is equipped with a solenoid valve assembly 7. The degreasing tank outlet pipe 7 is connected to the filter outlet and is equipped with a solenoid valve assembly 8.

[0028] The clear water tank 9 is equipped with a clear water tank inlet pipe 10 and a clear water tank outlet pipe 11, with the inlet pipe 10 located below the outlet pipe 11. The inlet pipe 10 is connected to the filter inlet and is equipped with a solenoid valve assembly 7 12. The outlet pipe 11 is connected to the filter outlet and is equipped with a solenoid valve assembly 8 13.

[0029] The cleaning solution tank 14 has a dosing pipe 15 at its bottom that connects to the filter inlet, and a solenoid valve assembly 17 is installed in the dosing pipe 15. The top of the cleaning solution tank 14 is open, and a cleaning pipe 16 connects the filter outlet to the top of the cleaning solution tank 14. A solenoid valve assembly 18 is installed in the cleaning pipe 16. The drain port of the filter unit 1 is connected to a tee, one port of which connects to a solenoid valve assembly 19, and the other port connects to a return pipe 20 between the tee and the top of the cleaning solution tank 14. A solenoid valve assembly 21 is installed in the return pipe 20.

[0030] The dosing tank 22 is used to store the cleaning solution, and a delivery pipe 23 is connected between the top of the tank and the cleaning solution tank 14. The delivery pipe 23 is equipped with a delivery pump 24. The delivery pump 24 is preferably a hydraulic pump.

[0031] The controller, filter unit 1, pressure sensor 2, solenoid valve group 1 7, solenoid valve group 2 8, solenoid valve group 7 12, solenoid valve group 8 13, solenoid valve group 6 17, solenoid valve group 3 18, solenoid valve group 5 19, solenoid valve group 4 21, electrically controlled exhaust valve 3, and transfer pump 24 are all electrically connected to the controller. The controller controls the operation of multiple solenoid valve groups and the transfer pump according to the set program and the detected pressure value or set time.

[0032] refer to Figure 1-2 The steps for controlling and using the energy-saving intelligent filtration system for purifying electroplating chemicals of the present invention are as follows:

[0033] 1. When the degreasing tank 4 is working, open solenoid valve group 7 and solenoid valve group 8, while keeping other valves closed. The filter unit is in normal operation, and liquid flows between filter unit 1 and degreasing tank 4 and the pipeline between them. At this time, turn on the transfer pump 24 again, inject 2 liters of cleaning solution, and then turn it off.

[0034] 2. When filter unit 1 becomes clogged and the pressure inside the main cylinder reaches 2MPa (or the set pressure value), solenoid valve group 7 and solenoid valve group 8 automatically close. At the same time, solenoid valve group 18 and solenoid valve group 21 open. This initiates a cleaning cycle for filter unit 1, dissolving the oil and grease within it.

[0035] 3. After cleaning the filter unit internally for 5 minutes (or the set time or internal pressure setting), solenoid valve group 3 (18) and solenoid valve group 4 (21) are closed, solenoid valve group 7 (12) is opened, and solenoid valve group 5 (19) is opened to discharge wastewater (wastewater after cleaning the filter unit). After 30 seconds (or the set time), the valves are closed. Solenoid valve group 6 (17) and solenoid valve group 3 (18) are opened, and solenoid valve group 7 (12) is closed, entering the filter unit 1 internal core cleaning cycle. At the same time, the transfer pump 24 is turned on, discharging 1 liter of cleaning solution and then turning off. After 2 minutes (or the set time), solenoid valve group 6 (17) and solenoid valve group 3 (18) are closed, solenoid valve group 7 (12) is opened, and solenoid valve group 5 (19) is opened to discharge wastewater for 30 seconds (or the set time). Then, solenoid valve group 8 (13) is opened, and solenoid valve group 5 (19) is closed, entering the clean water tank 9 for circulation.

[0036] 4. After the clean water tank circulates for 5 minutes (or the set time), close solenoid valve group 7 (12) and solenoid valve group 8 (13). At the same time, open solenoid valve group 1 (7) and solenoid valve group 2 (8) to begin the normal working cycle of the next degreasing tank 4.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
