Description

Technical Field

[0001] The invention relates to the technical field of water conservancy construction, in particular to a water resource processing and filtering device for water conservancy construction. Background Art

[0002] The rational use and treatment of water resources are crucial in water conservancy construction. With the continuous expansion of the scale of water conservancy projects and the increasing construction requirements, there are more stringent standards for the quality of water resources used in the construction process. In water conservancy construction, it is often encountered that the water source contains a large amount of impurities, silt, suspended matter and other pollutants. If these water resources are not effectively treated and filtered, it will not only affect the normal progress of the construction, but may also cause damage to the construction equipment and reduce the quality and efficiency of the project.

[0003] The existing water resource treatment and filtration devices have impurities accumulated during use, which will affect the filtration effect. Therefore, the impurities in the filtration device need to be cleaned after a period of use. The filtration device needs to be shut down for cleaning, which not only slows down the progress of construction and prolongs the construction time, but also makes the continuity and efficiency of water resource treatment and filtration low.

Flange connecting parts are installed on the bottom of the two connecting seats, and the bottoms of the two flange connecting parts are fixedly connected to sewage removal buckets. The bottom ends of the two sewage removal buckets are fixedly connected to electric valves, and the bottom ends of the two electric valves are fixedly connected to sewage pipes.

[0009] Preferably, the water inlet pipe and the diversion pipe are interconnected, and the rear end of the water inlet pipe is fixedly arranged between the output end of the water inlet pump.

[0010] Preferably, outer sides of the two cleaning brushes are tightly fitted and slidably rubbed against the two filter barrels, and the two cleaning brushes are disc brushes made of industrial nylon.

[0011] Preferably, the two sliding rods respectively penetrate and extend to the bottom of the two sealing covers, and the two sliding rods are respectively slidably connected to the two sealing covers.

[0012] Preferably, a contact rod is fixedly connected to the top end of the connecting shaft, and the contact rod is used for contacting a contact switch.

[0013] Preferably, the two connecting seats and the two flange connecting members are fixedly connected by bolts.

[0014] Preferably, the two sewage pipes are fixedly connected to each other, and both of the sewage pipes are fixedly arranged between the input end of the extraction pump.

[0015] Working principle: During water conservancy construction, when water resources need to be processed and filtered, start the water inlet pump, which extracts water resources so that water flows from the water inlet pipe into the diversion pipe. Under normal working conditions, water resources are evenly distributed to the two filter barrels through the diversion pipe.

[0016] The filter compartment in the filter barrel filters the water, and the filtered water flows out from the outlet pipe. When the filter compartment of one of the filter barrels is blocked, the water cannot smoothly enter the blocked filter barrel, causing the water pressure at the water inlet on the blocked side to rise rapidly, while the unblocked filter barrel works normally, and the pressure difference remains stable. This pressure difference causes the change plate in the diversion pipe to rotate toward the blocked side, thereby changing the direction of the water flow and directing the water resources to the unblocked filter barrel to ensure continuous filtering work;

[0017] As the pressure changes, the rotation of the changing plate drives the connecting shaft to rotate, and at the same time, the connecting shaft drives the contact rod to rotate together. When the contact rod contacts the corresponding contact switch, the electric valve on the corresponding side opens, and the extraction pump starts at the same time to carry out the cleaning work;

[0018] During the filtration and cleaning process, the extraction pump increases the extraction force of the dirt in the filter barrel, so that negative pressure is gradually formed in the filter barrel. With the continuous operation of the extraction pump and the pressure change, the slide rod slides out of the sliding sleeve under the action of pressure, the tension spring is stretched, and the slide rod descends to drive the cleaning brush to clean the blockage on the filter barrel. After the cleaning is completed, the extraction pump stops working. At this time, the electric valve is not closed, and the outside air enters the filter barrel through the gap of the extraction pump. The pressure of the filter barrel gradually recovers, and the slide rod is contracted and pulled back by the tension spring;

[0019] As the pressure in the clogged filter barrel is gradually restored after being cleaned, the resistance inside the filter barrel decreases, and the water pressure at the water inlet of the diverter pipe connected to the filter barrel will gradually drop to a normal level. The pressure difference on both sides of the changing plate in the diverter pipe will return to the initial equilibrium state, and the changing plate will also rotate accordingly to close to the initial position. As the changing plate rotates, the contact rod and the middle contact switch, and the electric valve is closed, allowing the two filter barrels to resume work according to normal flow distribution, that is, both filter barrels can normally inlet water for filtration.

[0020] The present invention provides a water resource treatment and filtering device for water conservancy construction, which has the following beneficial effects:

[0021] 1. The present invention sets two filter barrels and uses a changing plate to change the flow direction of water resources, so that the two filter barrels can work alternately. When the filter barrel in the filter barrel is blocked and needs to be cleaned, the changing plate rotates to direct the water resources to the other filter barrel, ensuring the continuous filtering work. The filtering work will not be stopped due to cleaning, thereby improving the continuity and efficiency of water resource treatment and filtration, and reducing work interruptions caused by cleaning of the filter barrel.

[0022] 2. The present invention cooperates with the diverter mechanism and the pressure difference. When the two filter barrels are working, the pressure difference on both sides of the changing plate in the diverter mechanism is relatively stable, and the water resources flow into the two filter barrels normally. When one side of the filter barrel is blocked, water is still continuously supplied, and the water cannot smoothly enter the blocked filter barrel, resulting in a rapid increase in the water pressure at the water inlet of the blocked filter barrel, while the unblocked filter barrel works normally and the pressure difference remains stable. Because the pressure at the blocked water inlet increases and the pressure on the other side remains unchanged, a pressure difference in the direction of the blocked filter barrel is generated on both sides of the changing plate. Under the action of this pressure difference, the changing plate in the diverter mechanism will slide to the blocked side, thereby ensuring that when one filter barrel is blocked, the water resources can automatically turn to the unblocked filter barrel, thereby improving the stability and reliability of the device.

[0023] 3. The present invention utilizes the characteristics of the tension spring itself. When the filter barrel is being cleaned, the slide rod will slide out of the slide sleeve as the pressure in the filter barrel changes, and the tension spring is continuously stretched. The slide rod descends, driving the cleaning brush to descend together to brush off the blockage on the filter barrel, and moves downward as the cleaning brush descends. When the cleaning is completed and the pressure in the filter barrel is restored, the slide rod is contracted and pulled back by the tension spring, thereby completing the cleaning of the filter barrel, reducing the blockage of the filter barrel, extending the service life of the filter device, and improving the filtering effect.

[0024] 4. The present invention increases the extraction force of dirt in the filter barrel through the extraction pump, and negative pressure is gradually formed in the filter barrel. As the extraction pump continues to work and the pressure changes, the sliding rod in the cleaning structure starts the cleaning work, which not only effectively enhances the cleaning effect of the dirt in the filter barrel, but also makes full use of the pressure change to automatically trigger the cleaning action, greatly improving the self-cleaning ability and operation efficiency of the filter device, and reducing the frequency and cost of manual maintenance.

[0025] 5. The present invention drives the contact rod to rotate together with the changing plate as the pressure changes, and as the contact rod rotates, the contact rod can contact the corresponding contact switch to realize the opening and closing of the extraction pump. There is no need for complex programming control or manual control operations, which greatly improves the automation degree and operation efficiency of the device and reduces labor costs and operating difficulties.

DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] Please see attached Figure 1 -Attached Figure 8The embodiment of the present invention provides a water resource treatment and filtering device for water conservancy construction, including a base 10, support legs 1 are fixedly connected to the left and right sides of the top of the base 10, a support ring 2 is fixedly connected between the two support legs 1, two filter barrels 4 are installed on the top of the support ring 2, a filter barrel 21 is fixedly connected to the bottom of the inner wall of the two filter barrels 4, a sealing cover 5 is installed on the top of the two filter barrels 4, and a cleaning structure is arranged on the top of the two sealing covers 5, and the cleaning structure is used to clean the filter barrel 21, a diverter pipe 12 is fixedly connected between the two filter barrels 4, a diverter mechanism is arranged in the diverter pipe 12, and the diverter mechanism is used to adjust the water inlet direction, an inlet pipe 24 is installed at the center position of the rear side of the diverter pipe 12, and a water inlet pump 7 is installed at the rear end of the inlet pipe 24, an indicator plate 11 is installed on the top of the diverter pipe 12, and a gasket 15 is fixedly connected to the front side of the top of the indicator plate 11, a sewage discharge mechanism is arranged at the bottom of the two filter barrels 4, and the sewage discharge mechanism is used to discharge the filtered material, an extraction pump 13 is fixedly connected to the top of the base 10, and an outlet pipe 3 is installed on the opposite side of the two filter barrels 4.

[0038] Two filter barrels 4 are provided to realize parallel processing. When one filter barrel 4 needs to be cleaned or maintained, the other filter barrel 4 can continue to work, thereby ensuring the continuity of the filtering work. The bottom of the inner wall of the two filter barrels 4 is fixedly connected with a filter partition barrel 21, which filters impurities and pollutants in the water to purify the water. At the same time, the sealing cover 5 ensures the sealing of the filter barrel 4 to prevent unfiltered water from overflowing from the top during the filtering process, and is also convenient for maintenance and cleaning of the inside of the filter barrel 4. The water inlet pump 7 provides the power for water inlet for the entire filtering device, extracts the water resources to be treated, and inputs it into the water inlet pipe 24 and then transports it to the diversion pipe 12;

[0039] The indicator plate 11 can intuitively display the working status of the diversion mechanism and the flow direction of the water flow through the angle change of the contact rod 14, which is convenient for operators to monitor and adjust. The extraction pump 13 enhances the extraction force of the dirt in the filter barrel 4 and improves the sewage discharge efficiency.

[0040] There are two filter barrels 4, and a diversion mechanism is used to change the flow direction of water resources. When the filter partition barrel 21 in one of the filter barrels 4 is blocked and needs to be cleaned, the diversion mechanism will direct the water resources to the other filter barrel 4, ensuring that the filtering work continues while cleaning the blocked filter barrel 4. The filtering work will not be stopped due to cleaning, which improves the continuity and efficiency of water resource treatment and filtration, reduces work interruptions caused by filter barrel cleaning, and realizes diversion through changes in pressure difference. There is no need for complicated control procedures, saving costs and energy consumption.

[0041] Please see attached Figure 1 and attached Figure 6The cleaning structure includes a sliding sleeve 6, which is fixedly connected to the sealing cover 5. A tension spring 18 is fixedly connected to the top of the inner wall of the sliding sleeve 6, a sliding rod 19 is fixedly connected to the bottom of the tension spring 18, a cleaning brush 20 is fixedly connected to the bottom of the sliding rod 19, the sliding rod 19 is located at the inner diameter of the sliding sleeve 6, and the sliding sleeve 6 and the sliding rod 19 are slidably connected.

[0042] The sliding sleeve 6 and the sliding rod 19, under normal filtering state, the sliding rod 19 is maintained in a certain position by the tension of the tension spring 18, and when the pressure in the filter barrel 4 changes, during the cleaning operation, the change in pressure will suck the sliding rod 19 out of the sliding sleeve 6, thereby driving the cleaning brush 20 to move downward, thereby cleaning the surface of the filter barrel 21, and can automatically adapt to different working conditions in the filter barrel 4, remove dirt and impurities on the filter barrel 21, and ensure the filtering effect and working efficiency of the filtering device.

[0043] Please see attached Figure 1 , Attachment Figure 3 and attached Figure 8 The shunt mechanism includes a changing plate 26, which is located at the inner diameter of the shunt tube 12. The changing plate 26 is fixedly connected with connecting shafts 25 on both the upper and lower sides. The top connecting shaft 25 is rotatably connected to the indicator disk 11. The top of the gasket 15 is fixedly connected with evenly distributed contact switches 16. The two connecting shafts 25 both penetrate and extend to the outer diameter of the shunt tube 12. The two connecting shafts 25 are rotatably connected to the shunt tube 12.

[0044] The size of the changing plate 26 is adapted to the inner diameter of the shunt pipe 12, and can effectively block and guide the water flow. The changing plate 26 is fixedly connected with connecting shafts 25 on both the upper and lower sides. The two connecting shafts 25 provide support and rotation capability for the rotation of the changing plate 26. At the same time, the top connecting shaft 25 can accurately reflect the rotation position and state of the changing plate 26 after being fixed to the indicator plate 11. Three contact switches 16 are installed on the gasket 15. The middle contact switch 16 is a control switch for closing the two electric valves 9. The contact switch 16 on the left side corresponds to the opening of the electric valve 9 on the left side. Similarly, the contact switch 16 on the right side corresponds to the opening of the electric valve 9 on the right side. And the rotation angle and position of the changing plate 26 can be observed through the rotation angle of the contact rod 14.

[0045] The diversion mechanism cooperates with the pressure difference, and the pressure difference on both sides of the changing plate 26 is relatively stable. The water resources flow into the two filter barrels 4 normally. When one side of the filter barrel 4 is blocked, water is still continuously supplied. The water cannot enter the blocked filter barrel 4 due to the blockage of the filter barrel 4, resulting in a rapid increase in the water pressure at the water inlet of the blocked filter barrel 4, while the unblocked filter barrel 4 works normally and the pressure difference remains stable. Because the pressure at the water inlet of the blocked filter barrel 4 increases, the pressure on the other side remains unchanged, and a pressure difference is generated on both sides of the changing plate 26 when the blocked filter barrel 4 is released. Under the action of this pressure difference, the changing plate 26 in the diversion mechanism will slide to the blocked side, thereby ensuring that when one filter barrel is blocked, the water resources can automatically turn to the unblocked filter barrel, thereby improving the stability of the device and the continuity of the filtering work.

[0046] Please see attached Figure 2 and attached Figure 5 -Attached Figure 7 The sewage discharge mechanism includes two connecting seats 22, and the two connecting seats 22 are fixedly connected to the two filter barrels 4 respectively. Flange connectors 23 are installed at the bottom of the two connecting seats 22. The bottoms of the two flange connectors 23 are fixedly connected to the sewage removal buckets 8. The bottom ends of the two sewage removal buckets 8 are fixedly connected to the electric valves 9, and the bottom ends of the two electric valves 9 are fixedly connected to the sewage pipes 17.

[0047] As the negative pressure 4 gradually forms in the filter barrel 4, the slide rod 19 slides out of the sliding sleeve 6 under the action of pressure, the tension spring 18 is stretched, and the slide rod 19 descends to drive the cleaning brush 20 to clean the blockage on the filter barrel 21. The cleaning is completed. At this time, the electric valve 9 is not closed yet, and the outside air enters the filter barrel 4 through the gap of the extraction pump 13. The pressure of the filter barrel 4 gradually recovers, and the slide rod 19 is contracted and pulled back by the tension spring 18, thereby reducing the blockage of the filter barrel, extending the service life of the filter device, and improving the filtering effect.

[0048] Please see attached Figure 8 The water inlet pipe 24 and the diversion pipe 12 are interconnected, and the rear end of the water inlet pipe 24 is fixedly arranged between the output end of the water inlet pump 7.

[0049] The input end of the water inlet pump 7 extracts water resources and inputs the extracted water resources into the diversion pipe 12 through the water inlet pipe 24 .

[0050] Please see attached Figure 6 The outer sides of the two cleaning brushes 20 are closely fitted with the two filter barrels 21 for sliding friction, and the two cleaning brushes 20 are disc brushes made of industrial nylon.

[0051] It can ensure that the cleaning brush 20 is in full contact with the surface of the filter barrel 21. At the same time, the industrial nylon material has excellent wear resistance, corrosion resistance and flexibility, so that the cleaning brush 20 is not easy to wear during long-term use and can maintain a good cleaning effect. The flexibility ensures that the cleaning brush 20 can adapt to different surface shapes and tiny unevenness when sliding closely with the filter barrel 21, ensuring comprehensive and thorough cleaning, and effectively improving the cleaning efficiency and cleaning quality of the filter barrel 21.

[0052] Please see attached Figure 6 The two sliding rods 19 respectively penetrate and extend to the bottom of the two sealing covers 5 , and the two sliding rods 19 are respectively slidably connected with the two sealing covers 5 .

[0053] The two sliding rods 19 are connected to the corresponding sealing covers 5 by welding.

[0054] Please see attached Figure 3 and attached Figure 4 A contact rod 14 is fixedly connected to the top of the top connecting shaft 25 , and the contact rod 14 is used to contact the contact switch 16 .

[0055] As the changing plate 26 rotates, it contacts the corresponding contact switch 16 .

[0056] Please see attached Figure 7 The two connection seats 22 and the two flange connection members 23 are fixedly connected by bolts.

[0057] Please see attached Figure 2 The two sewage pipes 17 are fixedly connected, and the two sewage pipes 17 are fixedly arranged between the input end of the extraction pump 13.

[0058] A three-way structure is formed between the two sewage pipes 17 and the input end of the extraction pump 13 , and the extraction pump 13 can act on both filter barrels 4 .

[0059] Embodiment 2:

[0060] The present embodiment is different from the above-mentioned embodiment in that the two filter barrels 4 can be used separately for filtering. When the filter barrel 4 on the left is used for filtering, the contact rod 14 is rotated 90° to the left, thereby driving the opening of the changing plate to face the left, so that water resources enter the filter barrel 4 on the left for filtering. When the filtering effect of the filter barrel 4 on the left is not good after working for a period of time, the contact rod 14 is rotated 180° from the left to the right, so that the contact rod 14 is turned to the far right, and then it can be replaced with the filter barrel 4 on the right to continue filtering.

[0061] 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.
