Description

Technical Field

[0001] The invention belongs to the technical field of electroplating wastewater filtration, and specifically refers to a water collecting column used for collecting wastewater from an electroplating line. Background Art

[0002] Electroplating wastewater is mainly composed of wastewater and waste liquid discharged from electroplating factories. Electroplating wastewater usually contains impurities such as suspended matter and particulate matter. These pollutants pose a serious threat to the environment and human health. Electroplating line wastewater filtration is an important link in electroplating wastewater treatment. Its purpose is to remove suspended matter, heavy metal ions, organic matter and other pollutants in the wastewater to meet environmental emission standards or achieve wastewater reuse.

[0003] The existing water collecting columns for wastewater collection have the following problems: When the existing water collecting columns for wastewater collection use quartz sand to filter wastewater, as the filtering process proceeds, the quartz sand filter material will gradually be blocked by impurities such as suspended matter and particulate matter in the wastewater, resulting in a decrease in filtration efficiency. In addition, the traditional water collecting columns for wastewater collection do not have the ability to detect the degree of permeability of the filtered water body, and thus cannot adjust the size of the gaps between the quartz sand filter materials. Therefore, they cannot meet the existing use requirements of water collecting columns for wastewater collection. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present solution provides a water collecting column for collecting wastewater from electroplating lines, which can not only reduce the probability of clogging of quartz sand filter media during water filtering operations, but also ensure that the quartz sand filter media can efficiently filter the water body.

[0005] The technical scheme adopted in this scheme is as follows: This scheme proposes a water collecting column for collecting wastewater from electroplating lines, including a water collecting column, a filter chamber, a dividing chamber mechanism, an upright type impurity filtering mechanism and a light-transmitting seam adjusting mechanism. The filter chamber is arranged inside the water collecting column, the dividing chamber mechanism is arranged inside the filter chamber, the upright type impurity filtering mechanism is arranged on the dividing chamber mechanism, the light-transmitting seam adjusting mechanism is arranged at the bottom of the water collecting column, the upright type impurity filtering mechanism includes a filter mechanism and an impurity isolation mechanism, the filter mechanism is arranged on the dividing chamber mechanism, the impurity isolation mechanism is arranged on the filter mechanism, the light-transmitting seam adjusting mechanism includes a water measuring mechanism and a stretching mechanism, the water measuring mechanism is arranged on the bottom side wall of the water collecting column, and the stretching mechanism is arranged on the side wall of the water collecting column.

[0006] As a further preferred embodiment of the present invention, the chamber division mechanism includes a rotating ring plate, a water outlet, a water inlet chamber and a water measuring chamber. The rotating ring plates are arranged in an array in pairs on the inner wall of the filter chamber. The rotating ring plate is rotatably arranged on the inner wall of the filter chamber. The water outlet is arranged on the inner wall of the rotating ring plate. The water inlet chamber is arranged at the top of the water collecting column. The water inlet chamber is arranged inside the filter chamber above the rotating ring plate. The water measuring chamber is arranged at the bottom of the water collecting column. The water measuring chamber is arranged inside the filter chamber below the rotating ring plate.

[0007] When in use, waste water from the electroplating line enters the water inlet chamber, and after being filtered, the waste water from the electroplating line falls into the water measuring chamber through the drain port.

[0008] Preferably, the filtering mechanism comprises an inlet valve, a linkage rod, a rubber cylinder, a filter screen, a quartz sand particle layer, a connecting cylinder and a water outlet, the inlet valve is arranged through the upper wall of the water collecting column, the inlet valve is connected to the water inlet chamber, the linkage rod is arranged between rotating ring plates in a group of two, the rubber cylinder is arranged between the rotating ring plates outside the water outlet, the rubber cylinder is arranged through, the filter screen is arranged on the rotating ring plate at the bottom of the linkage rod, the filter screen is arranged on the inner wall of the water outlet, the quartz sand particle layer is arranged inside the rubber cylinder above the filter screen, and the connecting cylinder is rotatably arranged between adjacent The connecting cylinder is set to be through-type, the water outlet is set on the side wall of the bottom of the water collecting column, and the water outlet is connected to the water measuring cavity; the isolation mechanism includes a driving magnet, a coil seat, a driving coil and a partition plate, the driving magnet is set on the inner wall of the filter cavity between the rotating ring plates, the coil seat is set on the bottom wall and the upper wall of the adjacent rotating ring plates, the coil seat is set vertically opposite to each other, the coil seat and the driving magnet are set horizontally opposite to each other, the driving coil is set on the outside of the coil seat, the partition plate is set on the upper wall of the rotating ring plate between the filter mesh plate and the rubber cylinder, and there is a gap between the partition plate and the inner wall of the rubber cylinder.

[0009] When in use, the electroplating line wastewater pipe is connected to the water inlet valve, and the electroplating line wastewater flows into the water inlet chamber through the wastewater pipe and the water inlet valve, and the wastewater inside the water inlet chamber flows into the rubber cylinder through the drain port, and the quartz sand particle layer inside the rubber cylinder uses the pores and gaps between its particles to filter out suspended matter and particulate impurities in the electroplating line wastewater, and the purified electroplating line wastewater flows into the water measuring chamber after the connecting cylinder, and the purified water inside the water measuring chamber is discharged through the outlet. As the filtration process proceeds, the pores and gaps inside the quartz sand particle layer will gradually be blocked by impurities such as suspended matter and particulate matter in the wastewater, resulting in a decrease in filtration efficiency. At this time, the driving coil is energized to generate magnetism, and a magnetic field is generated between the driving coil and the driving magnet. The rotating ring plate rotates under the action of the driving magnet and the magnetic field of the driving coil. The rotating ring plate drives the rubber cylinder to rotate under the connection of the linkage rod, and the quartz sand particle layer inside the rubber cylinder drives the centrifugal motion. The impurities filtered out in the pores and gaps inside the quartz sand particle layer move toward the inner wall of the rubber cylinder under the action of centrifugal motion, thereby reducing the probability of clogging of the quartz sand particle layer. The impurities thrown into the space near the inner wall of the rubber cylinder follow the water flow into the space between the partition plate and the inner wall of the rubber cylinder, completing the filtration operation of the wastewater.

[0010] Specifically, the water measuring mechanism includes a light intensity sensor and a spotlight, the light intensity sensor is arranged on the bottom side wall of the water collecting column, the detection end of the light intensity sensor is arranged through the inner wall of the water measuring cavity, the spotlight is arranged through the side of the water collecting column away from the light intensity sensor, and the spotlight and the detection end of the light intensity sensor are arranged opposite to each other; the stretching mechanism includes a strip magnet, a distance adjusting frame, an annular electromagnet and a magnetic conductive port, multiple groups of the strip magnets are arranged on the side wall of the rubber cylinder, multiple groups of the distance adjusting frame are arranged on the side wall of the water collecting column, the annular electromagnets are symmetrically arranged on the side of the distance adjusting frame close to the water collecting column, and multiple groups of the magnetic conductive ports are arranged at one end of the water collecting column close to the distance adjusting frame.

[0011] When in use, the gap distance between the quartz sand particle layers needs to be determined according to the actual water quality of the wastewater and the amount of water that needs to be treated. In the initial state, the rubber cylinder is in an elastically tightened state, and the quartz sand particle layers are tightly fitted together. At this time, the water flow speed is the slowest, and the annular electromagnet is energized to generate magnetism. The annular electromagnet and the strip magnet are set with opposite poles. The annular electromagnet is fixed to the side wall of the adjustable distance frame and absorbs the strip magnet by magnetic force. The strip magnet pulls the rubber cylinder, and the rubber cylinder expands to both sides using its own deformation ability. The squeezing force on the quartz sand particle layer is reduced, and the rotating ring plate drives the rubber cylinder to rotate, so that the quartz sand particle layer inside it is spread to a larger space, and the gap between the quartz sand particle layers is enlarged, thereby increasing the water flow rate. In order to prevent the gaps between the quartz sand particle layers from being too large, which may cause the filtered impurities to flow into the water measuring chamber with the water flow, a threshold value for detecting light intensity by the light intensity sensor is preset, and the light generated by the spotlight is received by the light intensity sensor. The light intensity sensor detects the light intensity generated by the spotlight passing through the water body. When the transmittance of the filtered water body in the water measuring chamber reaches the threshold value preset by the light intensity sensor, it means that the degree of filtration of the wastewater by the gap space between the quartz sand particle layers meets the user's requirements, which achieves the purpose of avoiding the blockage of the quartz sand particle layer during the water filtration operation and ensuring the efficient filtration of the water body by the quartz sand particle layer, thereby improving the filtration efficiency of the electroplating line wastewater to a certain extent.

[0012] Preferably, the model of the light intensity sensor is XKSR-3001-GZ.

[0013] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, the present invention utilizes the deformation capacity of the rubber cylinder. By setting up a cavity dividing mechanism, an upright impurity filtering mechanism and a light-transmitting seam adjusting mechanism, the filtering mechanism, the impurity separating mechanism, the water measuring mechanism and the stretching mechanism cooperate with each other. This can avoid the clogging of the quartz sand particle layer during the water filtering operation and ensure the efficient filtration of the water body by the quartz sand particle layer. The space formed by the partition plate and the inner wall of the rubber cylinder can intercept the impurities that fall off the quartz sand particle layer during the centrifugal movement, further reducing the probability of clogging of the quartz sand particle layer, thereby improving the filtration efficiency of the electroplating line wastewater to a certain extent. The rotating ring plate is in the belt During the rotation of the dynamic rubber cylinder, the quartz sand particle layer inside it is spread out to a larger space, the gaps between the quartz sand particle layers are enlarged, and the speed of water flow is increased. In order to prevent the gaps between the quartz sand particle layers from being too large, which may cause the filtered impurities to flow into the water measuring cavity with the water flow, a threshold for detecting light intensity by the light intensity sensor is preset, and the light generated by the spotlight is received by the light intensity sensor. The light intensity sensor detects the light intensity generated by the spotlight passing through the water body. When the transmittance of the filtered water body inside the water measuring cavity reaches the threshold preset by the light intensity sensor, it indicates that the degree of filtration of wastewater by the gap space between the quartz sand particle layers meets the user's requirements.

[0023] The model of the light intensity sensor 23 is XKSR-3001-GZ.

[0024] When in use, the electroplating line wastewater pipe is connected to the water inlet valve 10, and the electroplating line wastewater flows into the water inlet chamber 6 through the wastewater pipe and the water inlet valve 10, and the wastewater inside the water inlet chamber 6 flows into the rubber cylinder 12 through the drain port 5. The quartz sand particle layer 14 inside the rubber cylinder 12 uses the pores and gaps between its particles to filter out suspended matter and particulate impurities in the electroplating line wastewater. The purified electroplating line wastewater flows through the connecting cylinder 15 and then enters the water measuring chamber 7. The purified water inside the water measuring chamber 7 is discharged through the outlet 25. As the filtering process proceeds, the pores and gaps inside the quartz sand particle layer 14 will gradually be clogged by impurities such as suspended matter and particulate matter in the wastewater, resulting in a decrease in filtering efficiency. At this time, the driving coil 19 is energized to generate magnetism, and a magnetic field is generated between the driving coil 19 and the driving magnet 17. The rotating ring plate 4 rotates under the action of the driving magnet 17 and the magnetic field of the driving coil 19. The rotating ring plate 4 drives the rubber cylinder 12 to rotate under the connection of the linkage rod 11, and the rubber cylinder 12 drives the quartz sand particle layer 14 to perform centrifugal motion. The impurities filtered out in the pores and gaps inside the quartz sand particle layer 14 move toward the inner wall of the rubber cylinder 12 under the action of centrifugal motion, thereby reducing the probability of clogging of the quartz sand particle layer 14. The impurities thrown into the space near the inner wall of the rubber cylinder 12 follow the water flow into the space between the partition plate 20 and the inner wall of the rubber cylinder 12, thereby completing the filtering operation of the wastewater. The gap distance between the quartz sand particle layers 14 needs to be determined according to the actual water quality of the wastewater and the amount of water to be treated. In the initial state, the rubber cylinder 12 is in an elastically tightened state, and the quartz sand particle layers 14 are tightly fitted. At this time, the water flow speed is the slowest, and the annular electromagnet 29 is energized to generate magnetism. The annular electromagnet 29 and the strip magnet 27 are arranged with opposite poles. The annular electromagnet 29 is fixed to the side wall of the adjustable distance frame 28 and absorbs the strip magnet 27 by magnetic force. The strip magnet 27 pulls the rubber cylinder 12, and the rubber cylinder 12 expands to both sides by its own deformation ability. The squeezing force on the quartz sand particle layer 14 is reduced. The rotating ring plate 4 spreads the quartz sand particle layer 14 inside the rubber cylinder 12 to a larger space in the process of driving the rubber cylinder 12 to rotate, and the gap between the quartz sand particle layers 14 is enlarged, thereby improving the passing speed of the water flow. In order to prevent the gaps between the quartz sand particle layers 14 from being too large, causing the filtered impurities to flow into the water measuring chamber 7 with the water flow, a threshold value for detecting light intensity is pre-set by the light intensity sensor 23, and the light generated by the spotlight 24 is received by the light intensity sensor 23. The light intensity sensor 23 detects the light intensity generated by the spotlight 24 passing through the water body. When the transmittance of the filtered water body in the water measuring chamber 7 reaches the threshold value pre-set by the light intensity sensor 23, it means that the gap space between the quartz sand particle layers 14 meets the user's requirements for filtering the wastewater, which can avoid the blockage of the quartz sand particle layer 14 during the water filtering operation and ensure the purpose of efficient filtration of the water body by the quartz sand particle layer 14, thereby improving the filtration efficiency of the electroplating line wastewater to a certain extent; just repeat the above operation when using it next time.

[0025] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0026] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
