Description

Technical Field

[0001] The utility model relates to the technical field related to barrel bag pumps, in particular to a vertical multi-stage barrel bag pump. Background Art

[0002] In production and life, the transportation of water resources is a big problem. The natural state of water is rather special. Water flows to lower places under the influence of gravity. With the rapid development of the construction industry, the heights of various buildings are getting higher and higher. Therefore, the transportation of water resources requires the assistance of various mechanical equipment. Pumps are machines for transporting fluids or pressurizing fluids. There are many types of pumps, and vertical multi-stage barrel pumps are one of them. Vertical multi-stage barrel pumps have a small footprint and are simple and easy to use, so they are widely used.

[0003] The prior art has the following deficiencies: the prior art barrel pump cannot filter water when conveying water, causing debris in the water to enter the barrel pump, which not only pollutes the barrel pump but also easily causes clogging of the barrel pump. At the same time, when the barrel pump can filter water, the filter screen for filtering water is often installed in the water inlet end of the barrel pump. However, although the water can be filtered, the debris in the water adheres to the surface of the filter screen, which easily causes the mesh of the filter screen to be clogged, affecting the filtration efficiency. The staff is required to shut down the barrel pump from time to time and disassemble the filter screen for cleaning. However, when the filter screen is disassembled for cleaning, the barrel pump is in a closed state, which greatly affects the water conveying efficiency. Utility Model Content

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0019] The utility model proposes a vertical multi-stage barrel pump, comprising a barrel pump body 1, a water outlet pipe 2 is arranged on the barrel pump body 1, a water inlet pipe 3 is arranged on the barrel pump body 1, an end of the water inlet pipe 3 away from the barrel pump body 1 is connected with a ring member 4, and a connecting pipe 5 is connected on the outer wall surface of the ring member 4;

[0020] One end of the water outlet pipe 2 is fixedly connected to the barrel pump body 1, so that the water in the barrel pump body 1 can be discharged from the water outlet pipe 2. One end of the connecting pipe 5 is fixedly connected to the annular member 4, so that the water from the outside can flow into the annular member 4. At the same time, one end of the water inlet pipe 3 is fixedly connected to the barrel pump body 1, and the other end is fixedly connected to the annular member 4, so that the water in the annular member 4 can flow from the water inlet pipe 3 to the barrel pump body 1.

[0021] A pair of first circular plates 6 and a pair of second circular plates 7 are provided in the annular member 4, and a filter screen 8 is provided between the pair of first circular plates 6 and between the pair of second circular plates 7 respectively;

[0022] A pair of filters 8 are respectively fixedly installed between a pair of first circular plates 6 and a pair of second circular plates 7, and can be relatively fixed. At the same time, sliding a pair of first circular plates 6 and a pair of second circular plates 7 can drive a pair of filters 8 to move. At this time, a pair of filters 8 are respectively between the water inlet pipe 3 and the connecting pipe 5, and filter the water flowing from the connecting pipe 5 to the annular member 4. When the filter 8 between the pair of first circular plates 6 filters the water, the staff can take out the pair of second circular plates 7 outside the annular member 4, and clean the debris filtered out of the surface of the filter 8 between them. Conversely, take out the pair of first circular plates 6 and clean the filter 8 between them.

[0023] Sealing covers 9 are respectively provided at both ends of the annular member 4, a through hole is formed in the sealing cover 9, a driving rod 10 is provided in the through hole, and one end of a pair of driving rods 10 located in the annular member 4 is respectively connected to a first circular plate 6 and a second circular plate 7;

[0024] A pair of sealing covers 9 are respectively threadedly connected to the two ends of the annular member 4, so as to seal the annular member 4. At the same time, one end of a pair of driving rods 10 located in the annular member 4 is respectively fixedly connected to one end surface of a pair of first circular plates 6 and a second circular plate 7, so as to be relatively fixed. When the staff pushes the driving rod 10 connected to the second circular plate 7, the pair of second circular plates 7 can be moved, and a thrust can be applied to the pair of first circular plates 6, so that the driving rod 10 connected to a first circular plate 6 can slide out to the outside of a through hole, thereby realizing the switching of the filter screen 8, making it convenient for the staff to clean the switched filter screen 8, so as to improve the filtering efficiency of water.

[0025] Specifically, the circumferential surfaces of the first circular plate 6 and the second circular plate 7 are respectively formed with an annular groove 11, and a rubber sealing ring 12 in contact with the inner wall surface of the annular member 4 is arranged in the annular groove 11;

[0026] Under the action of the rubber sealing ring 12, the gap between the circumferential surface of the first circular plate 6 and the second circular plate 7 and the inner wall surface of the annular member 4 can be sealed to prevent water from leaking from the gap therebetween, causing waste of water resources and affecting the water transportation efficiency.

[0027] Specifically, a support rod 13 is fixedly installed between the pair of first circular plates 6 and between the pair of second circular plates 7;

[0028] Under the action of the support rod 13, a pair of first circular plates 6 and a pair of second circular plates 7 can be fixed to each other, so that the first circular plates 6 and the second circular plates 7 can slide more stably when sliding in the ring member 4.

[0029] Specifically, a limit block 14 is fixedly installed on the inner wall surface of the sealing cover 9;

[0030] The limit blocks 14 on the inner wall surfaces of a pair of sealing covers 9 can limit the sliding positions of the first circular plate 6 and the second circular plate 7 respectively, so that when a pair of filters 8 are switched, the filter 8 can be located between the water inlet pipe 3 and the connecting pipe 5, thereby facilitating filtering of water.

[0031] Specifically, a through groove 15 is formed on the inner wall surface of the through hole, and a slider 16 slidably connected to the through groove 15 is provided on the outer surface of the driving rod 10;

[0032] The slider 16 is fixedly mounted on the surface of the driving rod 10 and can be fixed relatively thereto. At the same time, the slider 16 is slidably connected to the through groove 15, which can keep the sliding positions of the first circular plate 6 and the second circular plate 7 in the annular member 4 fixed, so that the filter screen 8 is in a vertical state, and prevents the first circular plate 6 and the second circular plate 7 from sliding in the annular member 4, causing the filter screen 8 to rotate to a horizontal state, causing the unfiltered water in the connecting pipe 5 to flow into the water inlet pipe 3, thereby improving the filtering quality.

[0033] Specifically, an observation window 17 is provided in the outer wall of the ring member 4;

[0034] The observation window 17 can facilitate the staff to observe the amount of debris filtered out by the filter 8. When too much debris is filtered out and has affected the filtering efficiency of water, it is convenient for the staff to switch the filter 8 and clean the replaced filter 8.

[0035] Working principle: in actual use, the barrel bag pump body 1 is started to make the external water flow into the annular member 4 through the connecting pipe 5. At this time, the filter screen 8 between the pair of first circular plates 6 filters the water in the annular member 4, and the filtered water enters the barrel bag pump body 1 through the water inlet pipe 3, and then flows out through the water outlet pipe 2. At this time, the staff uses the observation window 17 to observe the situation in the annular member 4. When it is observed that too much debris is filtered out of the filter screen 8 between the pair of first circular plates 6 and affects the filtering efficiency, the staff pushes the driving rod 10 connected to a second circular plate 7, and makes the slider 16 on the driving rod 10 slidably connected to the through groove 15. At this time, the pair of second circular plates 7 slide in the annular member 4 to apply a thrust to the pair of first circular plates 6 to make them slide. At this time, the filter screen 8 between the pair of second circular plates 7 slides between the water inlet pipe 3 and the connecting pipe 5, and replaces the filter screen 8 between the pair of first circular plates 6, taking over the water inlet. Filtering is carried out. At this time, the slider 16 on the driving rod 10 connected to a first circular plate 6 is separated from the through groove 15, which is convenient for the staff to rotate the sealing cover 9 close to the first circular plate 6 and open one end of the ring member 4, so as to take out a pair of first circular plates 6 from the ring member 4 and clean the filter screen 8 therebetween. On the contrary, when too much debris is filtered out on the filter screen 8 between a pair of second circular plates 7, affecting the filtering efficiency of water, the staff pushes the driving rod 10 connected to the first circular plate 6 to replace the filter screen 8 between the pair of first circular plates 6 with the filter screen 8 between the pair of second circular plates 7, so as to take out a pair of second circular plates 7 from the ring member 4 and clean the debris attached to the filter screen 8 therebetween. The device can realize the cleaning of debris filtered out by the filter screen 8 during the process of the barrel bag pump body 1 pumping water, thereby improving the water conveying efficiency of the barrel bag pump body 1 and bringing convenience to people.
