Description

Technical Field

[0001] The invention relates to the technical field of water utilization equipment, in particular to a pump that prevents mud and sand from silting and blocking. Background Art

[0002] An integrated pump station is an integrated water pump system that modularizes components such as pumps, pipes, control systems, and cylinders to achieve functions such as rainwater collection. Its core advantages lie in its small footprint, easy installation, and high degree of automation, making it widely used in various fields.

[0003] The invention of the existing publication number CN119571912B discloses an integrated prefabricated pump station automatic cleaning and flushing device, which adds fan blades and sets a cleaning grid machine to the existing submersible pump to fully mix and break up the water flow at the bottom of the water inlet cavity, so that the impurities in the incoming water flow are fully broken up, and the speed of silt and impurity deposition is reduced. The submersible pump is suspended in the air through the bottom crossbeam to avoid water inlet blockage, and the cleaning pipe of the reverse water inlet is used to clean the interior. During the water inlet process, the fan blades rotate, extend and retract laterally, and spray water to fully clean the inner wall of the water inlet cavity, so that the silt deposited at the bottom is fully broken up and The mixed water flow is discharged. Although the above scheme can fully break up the muddy water entering the cylinder, due to the relatively large aperture of the grille at the water inlet end of the integrated pump, when the water body sent in contains large particles of hard mud, it will fall everywhere in the cylinder with the inertia of the water flow. At this time, the large particles of hard sand and gravel are easily damaged when they are pumped out normally with the mixed water flow. In addition, the existing backwash water mostly passes through a side pipe with a valve opened and closed on the main line. As the pressurized pump of the main line delivers water, a part of it will be separated to wash the bottom of the cylinder at high speed. At this time, it is easy for the muddy water to be blocked at the flushing port when passing through the smaller side pipe, and the flushing efficiency is poor. Summary of the Invention

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] Please see the attached Figure 1-12 , this application provides the following technical solutions.

[0035] Embodiment 1: A pump for preventing mud and sand from silting and blocking, comprising an integrated pump 1, a collecting inlet pipe 2 is provided for the connection of the integrated pump 1, a filter grille box 3 is provided on the side of the integrated pump 1 close to the collecting inlet pipe 2, a partition mounting plate 4 is installed at the lower end of the integrated pump 1 by a number of bolts, a retention separation area 6 is clamped between the partition mounting plate 4 and the bottom of the integrated pump 1, the upper end of the partition mounting plate 4 is connected to the retention separation area 6 and a vertical flow guide cover 5 is vertically provided, and the upper side of the vertical flow guide cover 5 surrounds the filter grille box 3. During normal use, the collecting inlet pipe 2 sends the collected water after preliminary filtration into the integrated pump 1, and when the collected water enters the integrated pump 1 through the collecting inlet pipe 2, the large-sized pollutants are further separated by the filter grille box 3, and the separated mixed water containing mud and sand particles flows downward under the diversion action of the vertical flow guide cover 5, and at this time the mud and sand and water enter the retention separation area 6.

[0036] The filter assembly is provided to intercept large particles of silt, and the filter assembly is arranged on the partition mounting plate 4. The filter assembly includes two first filter plates 8 and a plurality of second filter plates 24. Two first filter holes 7 are formed on both sides of the partition mounting plate 4. The two first filter plates 8 are horizontally inserted into the two first filter holes 7 respectively. A raised ring is provided on the upper end of the outer peripheral side of the partition mounting plate 4. The lower end of the raised ring is connected to the retention separation area 6 and a plurality of vertical grooves 22 are provided. The plurality of vertical grooves 22 are all penetrated by the inner side of the raised ring and a plurality of second filter holes 23 are provided. The second filter plates 24 are inserted into the plurality of second filter holes 23, and the lower ends of the second filter holes 23 are flush with the upper ends of the partition mounting plate 4. The collected water entering the retention separation area 6 below the partition mounting plate 4 is guided by the vertical flow guide cover 5. Under the action of water flow, it flows from the first filter plate 8 position of the partition mounting plate 4 from bottom to top. During the flow, large particles of silt that may affect the later submersible pump are directly separated, and mixed water and silt with fine particles can pass normally.

[0037] Since the height of the raised ring is higher than the upper end surface of the partition mounting plate 4, the lower end of the second filter hole 23 is flush with the upper end of the partition mounting plate 4. At this time, part of the flowing water retained in the partition area 6 will enter the vertical groove 22 under the action of the water flow, and then be discharged after being filtered from the second filter plate 24. The second filter plate 24 can also directly separate the large particles of sediment that affect the later submersible pump. Then, the water flowing out of the second filter plate 24 flows on the upper surface of the partition mounting plate 4 when passing through the second filter hole 23 with a smaller diameter. Then, in conjunction with the flowing water of multiple second filter holes 23, multiple streams collide or collide with the components above the partition mounting plate 4 to form a liquid disturbance, thereby disturbing the deposited sediment above the partition mounting plate 4, so as to realize the collection input pipe 2. As long as the sediment above the partition mounting plate 4 is disturbed, the problem of sediment silt being difficult to clean due to long-term silt accumulation and agglomeration can be avoided as much as possible.

[0038] A flushing assembly is provided to regularly process the silt and sediment at the bottom of the integrated pump 1. The flushing assembly includes a control seat 10, a connecting cover 11, a connecting rod 12, a metal filter ball 29 and a plurality of stirring pipes 26. Two output pumping pipes 35 are symmetrically provided on the upper end of the partition mounting plate 4. A side branch pipe 34 is provided on one side of the upper end of the two output pumping pipes 35. The side branch pipe 34 is connected to the connecting cover 11 and the connecting rod 12. The control seat 10 is provided at the center of the partition mounting plate 4. The connecting cover 11 is connected to the connecting rod 12. The bolt is fixed to the upper end of the control seat 10, and the connecting rod 12 passes through the center of the plug-in control seat 10 through the sealed bearing. The upper end of the connecting rod 12 is plugged into the connecting cover 11 and is provided with a throwing plate 13. The upper end of the throwing plate 13 is provided with a centrifugal blade. The upper ends of the two output pumping pipes 35 pass through the integrated pump 1. The two side branch pipes 34 are connected to the output pumping pipes 35 and one end is provided with a stop valve. The lower end of the side branch pipe 34 is connected to the center of the upper end of the connecting cover 11. The outer peripheral side of the connecting cover 11 is connected to the outer peripheral side of the connecting cover 11. The lower end is provided with a plurality of surface flushing holes 33, and the lower end of the surface flushing holes 33 is flush with the upper end of the partition mounting plate 4. When the submersible pump connected to the output pumping pipe 35 pumps water out at high pressure, there is high-speed flowing liquid in the output pumping pipe 35. At this time, the stop valve connecting the side branch pipe 34 and the output pumping pipe 35 is opened. The opening time can be customized according to the usage scenario. When the drainage inside and outside the output pumping pipe 35 is diverted into the side branch pipe 34, it will flow into the connecting cover 11, and then flush the surface of the partition mounting plate 4 horizontally from the surface flushing holes 33 with high pressure, forming a greater stirring force than the disturbance caused by the water flow at the position of the second filter hole 23, mixing the mud and water on the surface of the partition mounting plate 4, and then discharging it normally through the output pumping pipe 35. In addition, when the high-speed water flow is ejected from the surface flushing hole 33 and disturbs the water body above the partition mounting plate 4, the disturbed water body can laterally impact the vertically arranged second filter plate 24, thereby realizing basic flushing of the second filter plate 24.

[0039] The center of the connecting rod 12 passes through the ejection disk 13 to open a connecting groove 17, and the metal filter ball 29 is placed in the connecting cover 11. The lower end of the metal filter ball 29 is connected with a plug-in tube 30. The lower end of the plug-in tube 30 is plugged into the connecting groove 17 of the ejection disk 13 and fixed by bolts. The diameter of the metal filter ball 29 is smaller than the diameter of the ejection disk 13. An arc-shaped brush plate 31 is provided on the side of the connecting cover 11 close to the metal filter ball 29. A plurality of bristles are provided on the side of the arc-shaped brush plate 31 close to the metal filter ball 29, and the bristles are in contact with the outside of the metal filter ball 29. A first cavity 14 and a The second cavity 16 and the connecting rod 12 are located on one side of the first cavity 14 and are provided with a toggle gear 15. When the output pumping pipe 35 discharges the mixed sludge water normally, part of the sludge water will flow back from the side branch pipe 34 to the connecting cover 11. At this time, the toggle gear 15 is driven to rotate by the servo waterproof motor and the driving gear, and then the connecting rod 12 and the throwing-out plate 13 rotate at high speed in the connecting cover 11. At this time, the throwing-out plate 13 will centrifugally throw the mud and sand particles and sewage entering the connecting cover 11 to the surface flushing hole 33 at high speed, and discharge them through the surface flushing hole 33. The number of surface flushing holes 33 can be customized according to needs.

[0040] The connecting rod 12 passes through the lower end of the control seat 10 and is provided with a diverter box 25. The diverter box 25 is connected to the connecting groove 17 and a second diverter groove 28 is opened. A number of stirring pipes 26 are horizontally symmetrically arranged on the diverter box 25. The number of stirring pipes 26 are connected to the second diverter groove 28, and a number of flushing holes 27 are opened in the stirring pipe 26 at an angle downward. The two output pumping pipes 35 are staggered with the two first filter plates 8. The vertical guide cover 5 is staggered with the output pumping pipe 35 and the first filter plate 8. The partition mounting plate 4 is located below the output pumping pipe 35 and abuts against the bottom of the integrated pump 1. An auxiliary support rod 32 is provided to receive the high-speed water flow sent in by the branch pipe 34 in the connecting cover 11. When the metal filter ball 29 is turned on, the silt sent from the branch pipe 34 is further refined and filtered. The filtered water flows into the connecting groove 17 of the connecting rod 12 through the plug-in pipe 30, and then flows to the plurality of stirring pipes 26 through the second diversion groove 28 of the diversion box 25. The high-pressure water flow entering the stirring pipe 26 is inclined to rush toward the bottom surface of the integrated pump 1 through the plurality of flushing holes 27. Then, as the connecting rod 12 rotates at a high speed, the water in the retention separation area 6 can be vortex-stirred through the plurality of stirring pipes 26. Then, accompanied by the flushing water flow, the silt in the retention separation area 6 is mixed, and then, after passing through the first filter plate 8, it is sucked out by the output pumping pipe 35.

[0041] In addition, when the connecting rod 12 controls the high-speed rotation of the ejection disk 13, the metal filter ball 29 also rotates at a high speed. At this time, the bristles of the arc-shaped brush plate 31 can relatively clean the surface of the metal filter ball 29, thereby improving the filtering quality of the metal filter ball 29.

[0042] Example 2: On the basis of Example 1, the connecting rod 12 is located on the inner and outer circumferential sides of the second cavity 16 and is connected to the connecting groove 17, and a plurality of through holes 18 are opened. A second diverter groove 19 is opened around the first filter plate 8 in the partition mounting plate 4. One side of the two second diverter grooves 19 is connected to the second cavity 16 and is provided with a transfer groove 20. The partition mounting plate 4 is located at the upper end of the second diverter groove 19 and is connected to a plurality of filter plate recoil heads 21. The partition mounting plate 4 is located above the first filter plate 8 and is provided with a recoil spoiler 9 by bolts. The plurality of filter plate recoil heads 21 are tilted and point to the inner wall of the recoil spoiler 9, and A downward curved opening is provided at the center of the filter plate recoil head 21. A portion of the fine filtered water collected in the communication groove 17 enters the second diversion groove 19 through the adapter groove 20, and then rushes from the plurality of filter plate recoil heads 21 to the curved inner wall of the recoil spoiler 9. Then, under the action of the pressurized jets of the plurality of filter plate recoil heads 21, a vortex is formed between the recoil spoiler 9 and the first filter plate 8, which backflushes the gaps in the first filter plate 8 and improves the filtration quality of the first filter plate 8. The flow rate fed into the side branch pipe 34 is greater than the sum of the discharge flows of the surface flushing hole 33, the flushing hole 27 and the filter plate recoil head 21.

[0043] In addition, the large particles of sediment filtered out by the first filter plate 8 in the retained separation area 6 can be broken down and become smaller as the water flow stirs for a long time, and can be discharged normally through the first filter plate 8. If it still cannot be discharged, it will be sucked out by manual pump pipe or manually cleaned during the later major maintenance.

[0044] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
