Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment devices, and in particular to a dechlorination wastewater treatment device. Background Art

[0002] As we all know, dechlorination wastewater refers to water containing chloride ions (Cl⁻). Both industrial wastewater and domestic wastewater contain chloride ions. Dechlorination wastewater has significant harm to the environment, organisms and even water treatment facilities and pipelines. For this reason, we propose a dechlorination wastewater treatment device, which is a device used to assist in removing chloride ions from wastewater.

[0003] After searching, the Chinese patent publication number CN117886465A discloses a separation membrane wastewater treatment equipment and method, which is roughly described as including a treatment pool, a treatment chamber is provided in the treatment pool, and a filter component is provided in the treatment pool. The liquid filtered by the filter component enters the treatment chamber. When in use, the wastewater output from the water inlet pipe is filtered by setting a diverter, so that a part of the impurities are filtered out. The filtered impurities are discharged through the sewage outlet under the action of their own gravity. The diverter is not easy to be blocked. The filtered liquid is then processed by the separation membrane component, that is, the treatment pool has filtering and separation functions, thereby increasing the function of the filter pool and reducing the floor space of the wastewater treatment equipment. The Chinese patent publication number CN114590872A discloses an ultra-microfiltration membrane wastewater treatment The equipment is roughly described as including an ultra-microfiltration membrane wastewater treatment device, a pusher, a water inlet, a fixed lifting shell, a lifting clip and an ultra-microfiltration membrane device. The ultra-microfiltration membrane wastewater treatment device is provided with water inlets on the outer surfaces of both sides. When in use, it cooperates with the permeable mesh plate to filter the water source, and blocks the sludge inside the sewage through the limiting water guide strips on the surface of the permeable mesh plate. As the sludge hits, it cooperates with the slider to slide on the outer surface of the slide rod, and uses the elastic buffer wire on one end to buffer the impact of the slider. It has the characteristics of isolating the sludge inside the sewage and slowing down the high-speed flowing water source, solving the problem that the sewage contains large pieces of sludge and the excessively fast flow rate will impact the membrane, thereby achieving the effect of isolating the sludge inside the sewage and slowing down the high-speed flowing water source.

[0004] Although the above-mentioned existing technical solutions can all achieve the filtering treatment of wastewater, their treatment methods are all that the wastewater continuously passes through the same filtering equipment, that is, the flow space during the wastewater treatment process is a single space. Therefore, as the wastewater treatment proceeds, wastewater residues will accumulate in the equipment, thereby affecting the normal treatment of the wastewater. Since there is no obvious boundary between the part that has been treated and the newly flowing wastewater, if this part of the residual wastewater is cleaned, it will inevitably affect the normal treatment of the wastewater, and its practicality needs to be further improved.

[0041] The reduction motor 8 in this embodiment is a conventional device purchased on the market and known to those skilled in the art. In the present invention, we only use it without improving its structure and function. For those skilled in the art, its setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of its instruction manual, and will not be described in detail here.

[0042] In summary, the working principle of the dechlorination wastewater treatment device is as follows: when in use, the dechlorination wastewater treatment device is first placed at the desired location, and the reduction motor 8 is connected to the control circuit according to the instructions. At the same time, the three quick-connect elbow pipes 49 are respectively connected to the corresponding external conveying pipelines, so that the dechlorination wastewater to be treated is connected to the water addition hole 15, the external residual concentrated dechlorination wastewater temporary storage container is connected to the sewage discharge hole 16, and the external clean water pipe is connected to the clean water hole 17. When the dechlorination wastewater is actually treated, the external dechlorination wastewater to be treated is first pumped into the water addition hole 15, and then the reduction motor 8 is powered on to run. The power-on of the reduction motor 8 realizes the rotation drive of the intermediate shaft 18, and the intermediate shaft 18 rotates through the end circular plate The synchronous transmission of the middle circular plate 20 and the middle circular plate 21 realizes the synchronous rotation drive of the multiple water storage pipes 9. Since the multiple piston discs 10 are respectively distributed in the multiple water storage pipes 9, the movement of the multiple water storage pipes 9 will drive the piston discs 10 therein to form a synchronous movement, and the movement of the piston discs 10 will also realize the synchronous movement of the traction rod 11 fixedly connected thereto. The movement of the traction rod 11 drives the driving disc 40 fixedly connected thereto to form a relative position movement relative to the gradually changing slope driving surface 38 and the annular limiting surface 39. When the driving disc 40 rotates through the area corresponding to the annular limiting surface 39, the corresponding water storage pipe 9 will also rotate through the water adding hole 15. With the inflow of the dechlorinated wastewater in the water adding hole 15 and the reduction of the stretched state of the elastic spring 14, the elastic spring 14 pulls the piston disc 10 in the corresponding The piston disc 10 slides in the water storage pipe 9 toward the direction close to the installation cover 12 to realize the corresponding water inflow in the water storage pipe 9. After the driving disc 40 contacts the annular limiting surface 39, the water inflow of the water storage pipe 9 is completed and the water storage pipe 9 just rotates through the water adding hole 15. When the water storage pipe 9 filled with dechlorinated wastewater is about to rotate into the corresponding area of ​​the water purification hole 17, the corresponding driving disc 40 also enters the gradual slope area of ​​the gradual slope driving surface 38, prompting the piston disc 10 to move in the water storage pipe 9 to the area away from the installation cover 12 to squeeze the dechlorinated wastewater in the water storage pipe 9, causing the water pressure of the dechlorinated wastewater to increase, so as to facilitate the dechlorinated wastewater to pass relative to the filter membrane 5. Considering the passing efficiency of the filter membrane 5, the filtration of the dechlorinated wastewater requires a period of time, so the water purification hole 17 The structure is designed as an arc strip, so the dechlorinated ion wastewater can be formed in the state of synchronous rotation of multiple water storage pipes 9 during the process of passing through the filter membrane 5. When the gradually sloped driving surface 38 does not form further movement of the driving disk 40 relative to the water storage pipe 9, the piston disk 10 forms a relatively stable position in the corresponding water storage pipe 9, and the piston disk 10 maintains a relatively stable position in the corresponding water storage pipe 9 until it passes through the drain hole 16. When the water storage pipe 9 rotates through the drain hole 16, it will be connected with the drain hole 16, so as to realize the flow and discharge of the residual concentrated dechlorinated ion wastewater in the water storage pipe 9 under its own gravity. After the residual concentrated dechlorinated ion wastewater is relatively discharged relative to the water storage pipe 9, it will first turn away from the drain hole 16 and turn through the water filling hole 15 again.In the process of passing through the water adding hole 15 again, the driving effect of the gradually sloped driving surface 38 relative to the driving disk 40 fails, and the driving disk 40 rotates again into the corresponding area of ​​the annular limiting surface 39, so that the dechlorinated wastewater can be added to the water storage pipe 9 again to achieve continuous treatment of the dechlorinated wastewater.

[0043] Furthermore, when the driving disc 40 rotates and enters the relative action area of ​​the gradually changing slope driving surface 38, the dechlorinated ion wastewater in the water storage pipe 9 is subjected to an increase in water pressure, which causes the dechlorinated ion wastewater to enter the elastic annular capsule 33 through the annular groove 32, causing the volume of the elastic annular capsule 33 to increase, causing the volume of the roller inner cavity to be compressed, and the increase in the volume of the elastic annular capsule 33 causes the intermediate ring 34 to be displaced relative to the built-in shaft 22. During the displacement of the intermediate ring 34 relative to the built-in shaft 22, the strip slide 30 is pushed through the hinge seat 35 and the transmission member 36, causing the cleaning bristles to move away from the intermediate shaft 18. During the synchronous rotation of multiple water storage pipes 9, under the relative meshing transmission action of the driving gear 25 and the linkage gear 24, the built-in shaft 22 can be rotated relative to the strip convex section 26. The rotating built-in shaft 22 drives the cleaning roller 23 and multiple strip slides 30 thereon to rotate synchronously, and the rotating strip slide 30 drives the cleaning brush strip 31 thereon to pass through the filter membrane 5. The auxiliary cleaning of the filter membrane 5 is achieved, and when the gradually sloped driving surface 38 no longer forms a further displacement drive on the driving disk 40, the pressure on the dechlorinated ion wastewater in the water storage pipe 9 no longer increases, and the filtration of the dechlorinated ion wastewater by the filter membrane 5 will further cause a reduction in the dechlorinated ion wastewater in the water storage pipe 9, so that the pressure of the dechlorinated ion wastewater in the water storage pipe 9 will be reduced. In this state, the elastic annular bag 33 will form an elastic contraction under its own elastic action, so that the strip slide 30 can be inserted and stored again relative to the radial strip groove 29, and the range of the cleaning brush strip 31 that is rotated and brushed will also be reduced. In this state, when the cleaning brush strip 31 moves with the water storage pipe 9, the cleaning brush strip 31 will not form a relative brushing contact in the corresponding circular groove 19, so that under the premise of ensuring the cleaning of the filter membrane 5, the friction loss of the cleaning brush strip 31 can be reduced, and the rotation of the cleaning brush strip 31 can also realize the self-washing cleaning of the cleaning brush strip 31 in the dechlorinated ion wastewater, which is more practical.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
