Description

Technical Field

[0001] The present application relates to the field of vortex pipeline pumps, and in particular to a vortex pipeline pump for impurity filtering. Background Art

[0002] The vortex pump is a vane pump, which is mainly composed of an impeller, a pump body and a pump cover. The impeller is a disc, and the blades on the circumference are evenly arranged radially. An annular flow channel is formed between the pump body and the impeller. The suction port and the discharge port are both on the outer circumference of the impeller. There is a partition between the suction port and the discharge port, thereby isolating the suction port and the discharge port;

[0003] Referring to the Chinese patent application with publication number CN219795587U, a corrosion-resistant vertical vortex pipeline pump is disclosed, wherein a cavity is formed between the top of the connecting frame and the outer shell, and the two ends of the pump cover are respectively connected to the water inlet and the water outlet, and the inner walls of the pump cover, the water inlet and the water outlet are coated with a corrosion-resistant material layer, and the stainless steel connecting frame structure on the outside thereof strengthens the connectivity between the rotating shaft and the pump cover, and the corrosion-resistant material layer coated on the inner side walls of the pump cover, the water inlet and the water outlet can play a protective role, and improve the smoothness and corrosion resistance of the impeller part in the pump cover and the inner cavity of the pump body, so as to reduce the friction loss of the fluid and increase the service life;

[0004] However, in the prior art, the wear of the pump body is reduced by optimizing the structure inside the pump body. However, the fluid usually contains impurities, which will be driven by the impeller to hit various places in the pump body and may accumulate in the pump body. The vortex pipeline pump needs to be carefully cleaned after each work is completed, and the subsequent cleaning and maintenance are more troublesome. For this reason, we designed a vortex pipeline pump with impurity filtration. Utility Model Content

[0005] An impurity filtering vortex pipeline pump provided in an embodiment of the present application can filter the fluid at the inlet pipe end of the pump body. Under the impact of the fluid, impurities enter the sewage pipe through the impurity collecting port, avoiding the accumulation of impurities in the pump body and facilitating the technical problem of subsequent maintenance.

[0006] The embodiment of the present application provides an impurity filtering vortex pipeline pump comprising a driving motor, a connecting cover, a pump body, a coupling and an impeller, wherein the two ends of the connecting cover are respectively fixedly connected to the driving motor and the pump body, the coupling is arranged in the connecting cover, the output end of the driving motor is fixedly connected to the impeller through the coupling, the pump body is connected with an inlet pipe and an outlet pipe, the inlet pipe is provided with an impurity filtering mechanism, and the impurity filtering mechanism comprises a filter screen for filtering impurities in the fluid to prevent the impurities from entering the pump body;

[0007] The output end of the driving motor drives the impeller in the pump body to rotate through the coupling. When the impeller rotates, the rotating impeller exerts force on the fluid, giving the fluid an impulse in the direction of fluid movement to transfer kinetic energy to achieve fluid transportation. The fluid enters the inlet pipe of the pump body and is filtered by the filter screen to retain impurities in the fluid. A debris collection port is opened at the end of the filter screen away from the driving motor, and the bottom of the debris collection port is connected to a sewage pipe to collect the retained impurities. After closing the control valve, the collecting cylinder is rotated and detached from the bottom of the sewage pipe, so that the impurities collected in the collecting cylinder can be dumped when the vortex pipeline pump is working normally.

[0008] The above technical solutions in the embodiments of the present application have at least the following technical effects:

[0009] 1. The present application sets a filter at the inlet pipe end of the pump body, and opens a debris collection port at the end of the filter away from the driving motor, and the bottom of the debris collection port is connected to the sewage pipe. The fluid at the inlet pipe end is filtered through the filter to prevent impurities in the fluid from entering the pump body, thereby reducing the cleaning steps of the vortex pipeline pump after each work is completed, and the subsequent cleaning and maintenance are simple and convenient.

[0010] 2. In the present application, the impurities after filtering are discharged into the sewage pipe through the impurity collecting port under the impact of the subsequent fluid, and a collecting cylinder is threadedly connected to the bottom of the sewage pipe. When a large amount of impurities accumulate in the collecting cylinder, the control valve is closed, and the collecting cylinder is rotated off from the bottom of the sewage pipe, and the collected impurities are dumped. The impurities collected in the collecting cylinder can be dumped when the vortex pipeline pump is working normally, without affecting the normal operation of the vortex pipeline pump.

[0011] In some embodiments, a debris collecting port is provided on the inlet pipe.

[0034] The vortex pump (also called vortex pump) is a vane pump. It is mainly composed of an impeller, a pump body and a pump cover. The impeller is a disc, and the blades on the circumference are evenly arranged in a radial pattern. An annular flow channel is formed between the pump body and the impeller, and the suction port and the discharge port are both on the outer circumference of the impeller. There is a partition between the suction port and the discharge port, thereby isolating the suction port and the discharge port.

[0035] In the corrosion-resistant vertical vortex pipe pump in the related technology, a cavity is formed between the top of the connecting frame and the outer shell, and the two ends of the pump cover are respectively connected to the water inlet and the water outlet, and the inner walls of the pump cover, the water inlet and the water outlet are coated with a corrosion-resistant material layer. The stainless steel connecting frame structure on the outside strengthens the connectivity between the rotating shaft and the pump cover, and the corrosion-resistant material layer coated on the inner side walls of the pump cover, the water inlet and the water outlet can play a protective role and improve the smoothness and corrosion resistance of the impeller part inside the pump cover and the inner cavity of the pump body, so as to reduce the friction loss of the fluid and increase the service life.

[0036] Based on this, in order to improve the problem in the related technology that impurities are driven by the impeller and hit various places in the pump body, and may accumulate in the pump body, the vortex pipe pump needs to be carefully cleaned after each work is completed, and the subsequent maintenance is more troublesome, the embodiment of the present application provides the following solution.

[0037] See also Figures 1 to 4 , an impurity filtering vortex pipeline pump comprises a driving motor 1, a connecting cover 2, a pump body 3, a coupling 6 and an impeller 7, the two ends of the connecting cover 2 are fixedly connected to the driving motor 1 and the pump body 3 respectively, the coupling 6 is arranged in the connecting cover 2, the output end of the driving motor 1 is fixedly connected to the impeller 7 through the coupling 6, the pump body 3 is connected with an inlet pipe 4 and an outlet pipe 5, the inlet pipe 4 is provided with an impurity filtering mechanism, the impurity filtering mechanism is used to filter impurities in the fluid to prevent impurities from entering the pump body 3, reduce the cleaning steps of the vortex pipeline pump after each work is completed, and facilitate later cleaning and maintenance;

The control valve 11 is arranged at one end of the sewage pipe 10 close to the dirt collecting port 9;

[0039] The effect of such arrangement is that a filter screen 8 is arranged at the end of the inlet pipe 4 of the pump body 3, and a collection port 9 is opened at the end of the filter screen 8 away from the drive motor 1, and the bottom of the collection port 9 is connected to the sewage pipe 10, and the fluid at the end of the inlet pipe 4 is filtered through the filter screen 8 to prevent impurities in the fluid from entering the pump body 3, and the filtered impurities are discharged into the sewage pipe 10 through the collection port 9 under the impact of the subsequent fluid;

[0040] The impurity filtering mechanism further includes a collecting cylinder, which is arranged at one end of the sewage pipe 10 away from the impurity collecting port 9, and the collecting cylinder is connected to the sewage pipe 10 by threads;

[0041] The effect of such a setting is that when a large amount of impurities accumulate in the collecting cylinder, the collected impurities are dumped out, and the opening and closing of the sewage pipe 10 are controlled by the control valve 11. After closing the control valve 11, the collecting cylinder is rotated and detached from the bottom of the sewage pipe 10, so that the impurities collected in the collecting cylinder can be dumped out when the vortex pipeline pump is working normally, without affecting the normal operation of the vortex pipeline pump.

[0042] See also Figure 3 and Figure 4 , an internal thread is provided in the inlet pipe 4, and a mounting ring is coaxially fixedly connected to the outer ring of the filter screen 8, and an external thread matching the internal thread is provided on the outer side of the mounting ring;

[0050] From the above, we can see that the working principle of this application is as follows:

[0052] The filtered impurities are discharged into the sewage pipe 10 through the impurity collecting port 9 under the impact of subsequent fluids, and the bottom of the sewage pipe 10 is threadedly connected with a collecting cylinder. When a large amount of impurities accumulate in the collecting cylinder, the collected impurities are dumped by rotating the collecting cylinder off from the bottom of the sewage pipe 10, and a control valve 11 is provided on the sewage pipe 10 to control the opening and closing of the sewage pipe 10. After closing the control valve 11, the impurities collected in the collecting cylinder can still be dumped when the vortex pipeline pump is working normally, without affecting the normal operation of the vortex pipeline pump.
