Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a pre-treatment water collection device capable of quickly cleaning impurities in wastewater. Background Art

[0002] Domestic sewage refers to wastewater discharged by people in their daily life activities. This wastewater is mainly polluted by domestic waste and human excrement. The quantity, composition and concentration of pollutants are related to people's living habits and water consumption. Domestic sewage generally does not contain toxic substances, but it has conditions suitable for the reproduction of microorganisms and contains a large number of bacteria and pathogens. From a health point of view, it has certain hazards. Wastewater treatment is to use physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and even achieve wastewater recovery and reuse, and make full use of water resources. Since there are many sources of wastewater, it needs to be concentrated through water collection devices during its actual treatment process for subsequent treatment.

[0003] The existing water collection device is provided with multiple input ports, which can be connected to the wastewater discharge pipe through flanges, so that wastewater from multiple sources can be collected and discharged together for treatment. The wastewater can be pre-treated relatively simply in the water collector to clean up pollutants such as solid floating objects and particulate debris. The most common means at this stage is filtration. A relatively simple way is to set a filter plate at the inlet of the water collector or in the pipe of the water collector, and filter the pollutants through the filter holes opened on the plate body to ensure the passage of wastewater. However, this type of simple filtering mechanism has limited filtering effect and needs to be cleaned regularly. During the cleaning time, the water collection device cannot work, resulting in the overall low efficiency of the water collector in treating fixed pollutants in the wastewater. To this end, we have designed a pretreatment water collection device that can quickly clean impurities in wastewater to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a pre-treatment water collection device that can quickly clean impurities in wastewater, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a pretreatment water collection device that can quickly clean impurities in wastewater, comprising a base plate and a water collection pipe, the base plate and the water collection pipe are welded through a fixing seat, the top of the water collection pipe is fixedly installed with evenly distributed water inlet pipes, and the top of the water collection pipe is welded with connecting pipes corresponding to the water inlet pipes one by one, a fixing frame located on both sides of the water collection pipe is fixedly installed above the base plate, and an evenly distributed No. 1 electric telescopic column is fixedly installed on the top of the fixing frame, and a telescopic rod is connected to the outside of the No. 1 electric telescopic column. A filter plate is fixedly mounted on the end of the telescopic rod, and a filter groove matching the water inlet pipe and the connecting pipe is opened in the middle of the filter plate. A magnetic ring located outside the filter groove is mounted in the filter plate, and a connecting terminal associated with the magnetic ring is fixedly mounted on the outside of the filter plate, and the connecting terminal is electrically connected to the No. 1 electric telescopic column through a connecting line, and a flow electronic valve for controlling the opening and closing of the connecting pipe is mounted on the outside of the connecting pipe.

[0006] Furthermore, the water collecting pipe and the water inlet pipe are interconnected, and a water outlet is provided at the end of the water collecting pipe. The water inlet pipe can pass the wastewater input by the connecting pipe into the water collecting pipe, and concentrate it through the water collecting pipe. The concentrated wastewater is discharged through the water outlet at the end of the water collecting pipe.

[0007] Furthermore, the distance value between the water inlet pipe and the connecting pipe matches the thickness value of the filter plate, the filter tank is provided with evenly distributed filter holes, and the filter tank is recessed toward the inner side of the filter plate, and the filter plate can move to the middle of the water inlet pipe and the connecting pipe. At this time, the positions of the filter tank, the connecting pipe, and the water inlet pipe correspond to each other, ensuring that the wastewater is filtered through the filter tank when passing through.

[0008] Furthermore, a flange is provided at the top of the water inlet pipe, and the water collecting pipe and the water inlet pipe are connected by evenly distributed connecting rods. The top of the water inlet pipe can be connected to the wastewater drainage pipe through the flange, thereby ensuring that the wastewater can be introduced into the water collecting pipe.

[0009] Furthermore, a space matching the outside of the filter plate is reserved between the connecting rods, and the telescopic rod can drive the filter plate to move between the water inlet pipe, the connecting pipe and the connecting rod. When the No. 1 electric telescopic column is working, the telescopic rod can drive the filter plate to move above the water collecting pipe, thereby changing the position of the filter tank so that the filter tank corresponds to the water inlet pipe and the connecting pipe.

[0010] Furthermore, the outer part of the water collecting pipe is fixedly mounted with a No. 2 electric telescopic column which is evenly distributed, and the top part of the No. 2 electric telescopic column is fixedly mounted with a suction cabin which is located above the filter plate. The No. 2 electric telescopic column outside the water collecting pipe can drive the suction cabin to move outside the water collecting pipe. The suction cabin is located above the filter plate and can be moved by the No. 2 electric telescopic column to fit the upper surface of the filter plate.

[0011] Furthermore, the bottom of the suction cabin is provided with evenly distributed suction ports, the positions of which correspond one-to-one to the positions of the filter slots on the filter plate. After the suction cabin is moved by the No. 2 electric telescopic column to fit the upper surface of the filter plate, the suction ports are located on the outside of the filter slots.

[0012] Furthermore, a negative pressure pump is fixedly installed on the inner side of the fixing frame, and a connecting pipe is connected between the negative pressure pump and the suction cabin. When the negative pressure pump is working, the negative pressure in the suction cabin can be changed through the connecting pipe, and then the pollutants accumulated in the filter tank are absorbed through the suction port at the bottom of the suction cabin.

[0013] Furthermore, the No. 1 electric telescopic column is evenly distributed on both sides of the water collecting pipe, the distance between the two groups of No. 1 electric telescopic columns is greater than three times the length of the filter plate, the water inlet pipe and the connecting pipe are located in the middle position of the two groups of No. 1 electric telescopic columns, and when replacing the working filter plate, the No. 1 electric telescopic column currently in a working state drives the telescopic rod to retract, and drives the filter plate in the working state to move out from between the water inlet pipe and the connecting pipe, and the spare No. 1 electric telescopic column on the other side is started synchronously, and the telescopic rod is extended.

[0014] Furthermore, a control cabinet is fixedly installed on the outside of the base plate, and the control cabinet is electrically connected to the No. 1 electric telescopic column, the negative pressure pump, the flow electronic valve, and the No. 2 electric telescopic column. The flow electronic valve can be closed after a certain amount of wastewater has been counted and passed, and can be opened after the filter plate is replaced. The control cabinet can control the working status of each device, thereby ensuring the coordinated work between the mechanisms.

[0015] The present invention provides a pretreatment water collection device that can quickly clean impurities in wastewater, which has the following beneficial effects:

[0016] 1. The pretreatment water collection device that can quickly clean impurities in wastewater, through the coordinated use of the filter plate, the filter tank and the magnetic ring, makes the pretreatment water collection device that can quickly clean impurities in wastewater set a filter plate for filtering between the water inlet pipe and the connecting pipe, the filter tank in the middle of the filter plate is located corresponding to the water inlet pipe and the connecting pipe, when the wastewater flows through the filter tank on the filter plate, filtering is achieved, and the filtered solid pollutants are stored in the filter tank, and at the same time, when the wastewater passes through, the magnetic ring is powered by the connecting end and the connecting line, and a magnetic field is generated in the filter tank, which further improves the filtering effect of solid pollutants in the wastewater.

[0017] 2. The pretreatment water collection device that can quickly clean impurities in wastewater, through the coordinated use of No. 1 electric telescopic column, telescopic rod and flow electronic valve, makes it possible for the pretreatment water collection device that can quickly clean impurities in wastewater to be closed during operation after the flow electronic valve counts a certain amount of wastewater that has passed through, and at the same time, the No. 1 electric telescopic column at both ends of the water collection pipe is started, and the No. 1 electric telescopic column in the working state drives the telescopic rod to retract, and drives the filter plate in the working state to move out from between the water inlet pipe and the connecting pipe, and the No. 1 spare electric telescopic column on the other side is started synchronously, and the telescopic rod is extended to drive the spare filter plate to move to the water inlet pipe and the connecting pipe to work. After the movement is completed, the flow electronic valve is started and opened again, and the wastewater passing through is measured, so that the water collection device can automatically complete the replacement of the filter mechanism in a very short time, ensuring the passage of wastewater and the cleaning efficiency of solid pollutants.

[0018] 3. The pretreatment water collection device that can quickly clean impurities in wastewater, through the coordinated use of the negative pressure pump and the suction cabin and the connecting pipe and the suction port, makes it possible for the filter plate that has completed a period of filtering work to be pulled out, and then the pulled out filter plate moves to the bottom of the suction cabin under the action of the No. 1 electric telescopic column and the telescopic rod. At this time, the No. 2 electric telescopic column drives the suction cabin to descend until the suction port at the bottom of the suction cabin corresponds to the position of the filter tank outside the filter plate. After that, the negative pressure pump starts and creates negative pressure in the suction cabin through the connecting pipe, so as to extract the pollutants accumulated in the filter tank and clean them centrally, so that the filter plate can be quickly cleaned after completing one round of work and wait for the next round of work.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] See also Figures 1 to 4 The present invention provides a technical solution: a pretreatment water collection device that can quickly clean impurities in wastewater, including a bottom plate 1 and a water collecting pipe 2, the bottom plate 1 and the water collecting pipe 2 are welded through a fixing seat 21, the top of the water collecting pipe 2 is fixedly installed with evenly distributed water inlet pipes 10, and the top of the water collecting pipe 2 is welded with a connecting pipe 15 corresponding to the water inlet pipe 10 one by one, the water collecting pipe 2 and the water inlet pipe 10 are interconnected, the water inlet pipe 10 can pass the wastewater input by the connecting pipe 15 into the water collecting pipe 2, and concentrate it through the water collecting pipe 2, and the end of the water collecting pipe 2 is provided with a water outlet 20, and the concentrated wastewater is discharged through the water outlet 20 at the end of the water collecting pipe 2.

[0029] A fixing frame 6 located on both sides of the water collecting pipe 2 is fixedly installed above the base plate 1, and a uniformly distributed No. 1 electric telescopic column 4 is fixedly installed on the top of the fixing frame 6. The fixing frame 6 can provide a fixed installation position for the No. 1 electric telescopic column 4 and increase the height of the No. 1 electric telescopic column 4 so that the No. 1 electric telescopic column 4 can correspond to the position of the water inlet pipe 10 and the connecting pipe 15. The outside of the No. 1 electric telescopic column 4 is connected with a retractable telescopic rod 13.

[0030] See also Figures 3 to 7 The end of the telescopic rod 13 is fixedly sleeved with a filter plate 7, the distance value between the water inlet pipe 10 and the connecting pipe 15 matches the thickness value of the filter plate 7, and the filter plate 7 can move to the middle of the water inlet pipe 10 and the connecting pipe 15. At this time, the positions of the filter tank 18, the connecting pipe 15, and the water inlet pipe 10 correspond to each other, ensuring that the wastewater is filtered through the filter tank 18 when passing through. The filter tank 18 is provided with evenly distributed filter holes, and the filter tank 18 is recessed toward the inner side of the filter plate 7. When the filter plate 7 moves between the water inlet pipe 10 and the connecting pipe 15, the outside of the filter plate 7 can block the gap between the water inlet pipe 10 and the connecting pipe 15 to prevent wastewater leakage.

[0031] A flange is provided at the top of the water inlet pipe 10, and the top of the water inlet pipe 10 can be connected to the wastewater drainage pipe through the flange, so as to ensure that the wastewater can be introduced into the water collecting pipe 2. The water collecting pipe 2 and the water inlet pipe 10 are connected by evenly distributed connecting rods. The water collecting pipe 2 and the water inlet pipe 10 are connected by connecting rods, which can reserve a gap between the water inlet pipe 10 and the connecting pipe 15 for passing the filter plate 7. A space matching the outside of the filter plate 7 is reserved between the connecting rods. When the No. 1 electric telescopic column 4 is working, the filter plate 7 can be driven to move above the water collecting pipe 2 through the telescopic rod 13, thereby changing the position of the filter tank 18.

[0032] The telescopic rod 13 can drive the filter plate 7 to move between the water inlet pipe 10, the connecting pipe 15 and the connecting rod, so that the filter groove 18 corresponds to the water inlet pipe 10 and the connecting pipe 15. The model of the first electric telescopic column 4 is JINJE-1601. The middle part of the filter plate 7 is provided with a filter groove 18 matching the water inlet pipe 10 and the connecting pipe 15. The filter plate 7 is provided with a magnetic ring 19 located on the outside of the filter groove 18, and the outside of the filter plate 7 is fixedly installed with a connecting terminal 17 associated with the magnetic ring 19.

[0033] The connecting end 17 is electrically connected to the No. 1 electric telescopic column 4 through the connecting line 14. When wastewater passes through, the magnetic ring 19 is powered by the connecting end 17 and the connecting line 14 to generate a magnetic field in the filter tank 18, further improving the filtering effect of solid pollutants in the wastewater. The outside of the connecting pipe 15 is provided with a flow electronic valve 11 for controlling the opening and closing of the connecting pipe 15.

[0034] See also Figures 2 to 5 The outside of the water collecting pipe 2 is fixedly sleeved with a uniformly distributed No. 2 electric telescopic column 12. The No. 2 electric telescopic column 12 outside the water collecting pipe 2 can drive the suction cabin 9 to move outside the water collecting pipe 2. The top of the No. 2 electric telescopic column 12 is fixedly sleeved with a suction cabin 9 located above the filter plate 7. The suction cabin 9 is located above the filter plate 7 and can be moved to fit the upper surface of the filter plate 7 through the No. 2 electric telescopic column 12. The model of the No. 2 electric telescopic column 12 is YNT-03. The bottom of the suction cabin 9 is provided with uniformly distributed suction ports 16. After the suction cabin 9 moves to fit the upper surface of the filter plate 7 through the No. 2 electric telescopic column 12, the suction port 16 is located on the outside of the filter tank 18.

[0035] The position of the suction port 16 corresponds one-to-one to the position of the filter tank 18 on the filter plate 7, so as to facilitate the subsequent cleaning of the solid waste accumulated in the filter tank 18. A negative pressure pump 5 is fixedly installed on the inner side of the fixed frame 6. When the negative pressure pump 5 is working, the negative pressure in the suction cabin 9 can be changed through the connecting pipe 8, and then the pollutants accumulated in the filter tank 18 are absorbed through the suction port 16 at the bottom of the suction cabin 9. The negative pressure pump 5 is connected to the suction cabin 9 with a connecting pipe 8 to realize the cleaning of the filter plate 7. The principle and use process of the negative pressure pump 5 are the same as those in the prior art and will not be repeated here. The No. 1 electric telescopic column 4 is evenly distributed on both sides of the water collecting pipe 2. When the working filter plate 7 needs to be replaced, the No. 1 electric telescopic column 4 at both ends of the water collecting pipe 2 is started synchronously.

[0036] The distance between the two groups of No. 1 electric telescopic columns 4 is greater than three times the length of the filter plate 7. The water inlet pipe 10 and the connecting pipe 15 are located in the middle position of the two groups of No. 1 electric telescopic columns 4. During the replacement of the filter plate 7, the No. 1 electric telescopic column 4 currently in a working state drives the telescopic rod 13 to retract, and drives the filter plate 7 in a working state to move out from between the water inlet pipe 10 and the connecting pipe 15. The spare No. 1 electric telescopic column 4 on the other side is started synchronously, and the telescopic rod 13 is extended, driving the spare filter plate 7 to move to the water inlet pipe 10 and the connecting pipe 15 to work.

[0037] A control cabinet 3 is fixedly installed on the outside of the base plate 1. The control cabinet 3 can control the working status of each device, so as to ensure the coordination between the mechanisms and the overall automation level of the device. The control cabinet 3 is electrically connected to the No. 1 electric telescopic column 4, the negative pressure pump 5, the flow electronic valve 11, and the No. 2 electric telescopic column 12. The flow electronic valve 11 can be closed after a certain amount of wastewater has been counted and opened after the filter plate 7 is replaced. The principles and use processes of the control cabinet 3 and the flow electronic valve 11 are the same as those in the prior art and will not be repeated here.

[0038] In summary, the pretreatment water collection device can quickly clean impurities in wastewater. When in use, a group of filter plates 7 on the same side move to between the water inlet pipe 10 and the connecting pipe 15 under the action of the No. 1 electric telescopic column 4 and the telescopic rod 13 to work. The control cabinet 3 controls the working status of each device. The top of the water inlet pipe 10 is connected to the wastewater delivery pipeline through a flange. When the wastewater flows through the filter tank 18 on the filter plate 7, filtering is achieved. The filtered solid pollutants are stored in the filter tank 18. The flow electronic valve 11 counts the flow of wastewater passing through. At the same time, when the wastewater passes through, the magnetic ring 19 is powered by the connecting end 17 and the connecting line 14 to generate a magnetic field in the filter tank 18, further improving the filtering effect of solid pollutants in the wastewater. The flow electronic valve 11 is closed after counting a certain amount of wastewater passing through. At the same time, the No. 1 electric telescopic column 4 at both ends of the water collection pipe 2 is started synchronously. The No. 1 electric telescopic column 4 currently in the working state drives the telescopic rod 13 to retract, and drives the working state. The filter plate 7 is moved out from between the water inlet pipe 10 and the connecting pipe 15, and the spare No. 1 electric telescopic column 4 on the other side is started synchronously, and the telescopic rod 13 is extended to drive the spare filter plate 7 to move to the water inlet pipe 10 and the connecting pipe 15 to work. After the movement is completed, the flow electronic valve 11 is started and opened again, and the passing wastewater is measured. In a very short time, the replacement of the filtering mechanism is automatically completed. After the filter plate 7 that has completed the filtering work for a period of time is pulled out, the pulled out filter plate 7 moves to the bottom of the suction cabin 9 under the action of the No. 1 electric telescopic column 4 and the telescopic rod 13. At this time, the No. 2 electric telescopic column 12 is started and drives the suction cabin 9 to descend until the suction port 16 at the bottom of the suction cabin 9 corresponds to the position of the filter tank 18 outside the filter plate 7. After that, the negative pressure pump 5 works and creates negative pressure in the suction cabin 9 through the connecting pipe 8, and the pollutants accumulated in the filter tank 18 are extracted and cleaned up, completing the working process of the pretreatment water collection device that can quickly clean impurities in wastewater.
