Description

Technical Field

[0001] The utility model relates to the technical field of sewage pumps, in particular to a vertical sewage pump. Background Art

[0002] Vertical sewage pumps can be used as general pipeline pumps to pressurize water for high-rise buildings, and can also transport sewage containing granular fibers. In addition to transporting sewage, they are also suitable for use as drain pumps, filter flushing, condensation circulation pumps, etc., and are widely used. Therefore, the existing vertical sewage pumps have been continuously innovated and developed. Therefore, it can be seen that the current vertical sewage pumps basically meet people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN220581280U discloses a vertical sewage pump, which is provided with "including: a pump casing, a connecting device is provided at the top of the pump casing, a driving motor is provided at the top of the connecting device, a liquid inlet pipe is provided at the bottom of the pump casing, a liquid outlet pipe is provided on the pump casing, a filtering mechanism is provided at the bottom of the pump casing, the liquid inlet pipe is located in the filtering mechanism, and a number of support rods are evenly provided on the pump casing; a rotating shaft, one end of the rotating shaft is connected to the driving motor, and the other end of the rotating shaft extends into the pump casing and is sleeved with an impeller; by placing the sewage pump into a sewage pool and then starting the driving motor, the driving motor drives the impeller to rotate in the pump casing through the rotating shaft, so that sewage enters from the liquid inlet pipe and is discharged from the liquid outlet pipe; through the filtering mechanism, large pieces of garbage in the sewage are filtered before entering the liquid inlet pipe, so as to avoid clogging of the sewage pump."

[0004] However, when the above device is actually used, the liquid inlet pipe is arranged below the device, and a filter cover is arranged below the liquid inlet pipe. There is a fixed distance between the liquid inlet pipe and the ground. A large amount of garbage blocked by the filter cover is accumulated below and around it. Since it is difficult for the equipment to collect and remove a large amount of garbage in time, the filter cover is surrounded, which in turn affects the pumping of liquid from the liquid inlet pipe, causing the vertical sewage pump to be used unsmoothly. Therefore, a vertical sewage pump is urgently needed to solve the above problem. Utility Model Content

[0027] When using the vertical sewage pump, the motor 1 is turned on, and then the output end of the motor 1 drives the rotating shaft 4 to rotate, and then the rotating shaft 4 drives the connecting frame 5 to rotate, and then the connecting frame 5 drives the filter screen 6 to rotate, and at the same time, the rotating shaft 4 drives the impeller to rotate in the pump housing 2, so that sewage enters from the liquid inlet 17, and then passes through the filter screen 6 and is discharged from the liquid outlet 18 to complete the water delivery operation. The connecting frame 5 is in a V-shaped block shape, and the blocked large pieces of garbage fall downward along the inclined surface of the filter screen 6 on the connecting frame 5 and fall into the collection frame 7. When the collection frame 7 is full of garbage, the user drives the push block 8 to slide along the surface of the support frame 3, and then the push block 8 drives the baffle 9 to rotate along the inner wall of the support frame 3, thereby opening the support frame 3 and taking out the collection frame 7, which is convenient for cleaning and convenient use.

[0028] Furthermore, a liquid inlet 17 is provided on one side of the pump housing 2 , and a liquid outlet 18 is provided on one side of the pump housing 2 ; water is transported from the liquid inlet 17 to the pump housing 2 , and then discharged from the liquid outlet 18 for use.

[0029] See also Figure 1 , Figure 2 and Figure 5 , an embodiment provided by the utility model:

[0030] A fixing block 10 is provided at the bottom of the motor 1, a counterweight block 11 is fixedly installed at the bottom of the fixing block 10, and the rotating shaft 4 is connected to the inner wall of the counterweight block 11 through and through, a connecting block 12 is overlapped at the bottom of the fixing block 10, and the counterweight block 11 is connected to the inner wall of the connecting block 12 through and through, fastening bolts 16 are connected to both sides of the bottom of the connecting block 12 through and through, and the fastening bolts 16 are threadedly connected to the inner wall of the fixing block 10;

[0031] The fixing block 10 and the connecting block 12 are connected together by fastening bolts 16, and the connecting block 12 is fixedly connected to the top of the pump housing 2, so that the motor 1 is tightly connected to the pump housing 2, and the counterweight block 11 is used to increase the gravity of the motor 1 to avoid the problem that the motor 1 is not connected to the connecting block 12 through the fixing block 10 due to a large and upward external force and the fastening bolts 16 are loose.

[0032] Furthermore, the inner wall of the connection block 12 is provided with a threaded strip 13, the outer surface of the threaded strip 13 is threadedly connected with a fixing bracket 14, a sealing gasket 15 is fixedly installed at the bottom of the fixing bracket 14, and the sealing gasket 15 overlaps the inner wall of the pump housing 2;

[0033] By removing the fixing block 10 from the connecting block 12 and then driving the fixing frame 14 to rotate, the fixing frame 14 is separated from the threaded strip 13, and then the fixing frame 14 is taken out from the connecting block 12, and then the sealing gasket 15 is taken out, which facilitates the replacement of the sealing gasket 15, thereby ensuring the sealing effect of the connection between the pump housing 2 and the connecting block 12, and the fixing frame 14 itself can also limit and protect the rotating shaft 4 to avoid the rotating shaft 4 from shaking significantly and causing damage.

[0034] Working principle: when using the vertical sewage pump, by turning on the motor 1, the shaft 4 is driven to rotate, and then the shaft 4 drives the filter screen 6 to rotate through the connecting frame 5. At the same time, the impeller rotates with the shaft 4, so that the sewage is filtered through the filter screen 6 from the liquid inlet 17 and then transported to the liquid outlet 18 for discharge, completing the water delivery operation. The filter screen 6 is used to filter garbage to avoid the impeller being stuck or blocked by garbage, resulting in the vertical sewage pump being difficult to operate or not discharging water. In addition, the rotation of the filter screen 6 can throw out the garbage attached to the surface of the filter screen 6 to avoid the problem of the filter screen 6 being blocked and affecting the pumping. The connecting frame 5 is in a V-shaped block shape. The filter screen 6 arranged on the connecting frame 5 can guide the blocked large pieces of garbage to fall into the collection frame 7. By opening the support frame 3, the filter screen 6 can be removed. The collecting frame 7 is taken out, which is convenient for timely cleaning of the collecting frame 7, and avoids a large amount of garbage from being accumulated in the collecting frame 7 for a long time, causing odor and polluting the surrounding environment. In addition, the fastening bolts 16 connect the fixing block 10 and the connecting block 12 together, so that the motor 1 is tightly connected to the pump housing 2, and then the counterweight block 11 is used to increase the gravity of the motor 1, thereby stabilizing the motor 1 and ensuring the stability of the operation of the device. By rotating the fixing frame 14, the fixing frame 14 can be taken out of the connecting block 12, and then the sealing gasket 15 can be taken out, which is convenient for replacing the sealing gasket 15, ensuring the sealing effect of the connection between the pump housing 2 and the connecting block 12, and the diameter of the fixing frame 14 is larger than the diameter of the sealing gasket 15, which improves the sealing effect of the connection between the pump housing 2 and the connecting block 12.
