[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0025] The centrifugal pump water diversion and filtration device of the embodiment of the utility model includes a shell 1, a first filter component, a cleaning component 3 and a first collecting component 33. The filter component 2 includes a first filter component, which is suitable for being arranged in the shell 1. The cleaning component 3 includes a driving component 31 and a first cleaning component 32. The driving component 31 is connected to the first cleaning component 32, and the first filter component has a first preset angle with the axis of the shell 1. The first collecting component 33 is connected to the shell 1, and the collecting end of the first collecting component 33 faces the lowest point of the first filter component in the up and down direction.

[0026] Specifically, Figures 1 to 3 As shown, the shell 1 extends in the up-down direction, and the shell 1 has a accommodating chamber 11, and the accommodating chamber 11 has an inlet and an outlet, the inlet of the accommodating chamber 11 is the inlet of the shell 1, and the outlet of the accommodating chamber 11 is the outlet of the shell 1, the outlet of the accommodating chamber 11 is connected to the vacuum pump, and the outlet of the accommodating chamber 11 is connected to the centrifugal pump, and the outlet of the accommodating chamber 11 is arranged at the lower end of the shell 1, and the outlet of the shell 1 has a preset gap at the bottom of the shell 1 to prevent debris deposited at the bottom of the shell 1 from entering the centrifugal pump through the outlet.

[0027] The inlet of the accommodating chamber 11 is located at the upper end of the housing 1, the first filter component and the first cleaning component 32 are arranged in the housing 1, the driving component 31 is connected to the housing 1, and the driving end of the driving component 31 extends into the housing 1 and is connected to the first cleaning component 32, and the output end of the driving component 31 is connected to the first cleaning component 32 to drive the first cleaning component 32 to rotate, and then the first cleaning component 32 rotates to clean the debris on the upper end surface of the first filter component.

[0028] There is a first preset angle between the first filter component and the axis of the housing 1, that is, the first filter component has a first preset angle relative to the up-down direction, and the up-down direction can be understood as the gravity direction, that is, the first filter component is arranged obliquely in the housing 1.

[0029] In actual cleaning, the first filter component is circular, and the upper end surface of the first filter component is divided into a first area 24 and a second area 25. When the first cleaning component 32 does not start cleaning, the first cleaning component 32 is stopped on the higher side of the first area 24 and the second area 25 in the vertical direction. When cleaning starts, the centrifugal pump guides the water filter device, and the driving component 31 is started to drive the first cleaning component 32 to rotate in the first direction from the highest point of the first area 24 to the lowest point of the first area 24, thereby cleaning the debris on the first area 24 to the collection end of the first collecting component 33.

[0030] Subsequently, the driving component 31 is reversed, that is, the driving component 31 drives the first cleaning component 32 to return to the boundary line between the first zone 24 and the second zone 25, and then the driving component 31 continues to reverse, and the first cleaning component 32 rotates from the highest point of the second zone 25 to the lowest point of the second zone 25, and then the debris on the second zone 25 is swept to the collecting end of the first collecting component 33, so as to avoid the first cleaning component 32 rotating only in the first direction, causing the debris in the first zone 24 and the second zone 25 to be crushed under the cleaning of the first cleaning component 32 and pass through the first filter component, or to be understood as reducing the probability that the first cleaning component 32 rotates only in the first direction and causes the debris in the first zone 24 and the second zone 25 to be crushed under the cleaning of the first cleaning component 32, so as to avoid the particle size of the debris becoming smaller during the cleaning process, causing it to pass through the first filter component, thereby improving the efficiency and stability during cleaning.

[0031] Arranging the first filtering component in an inclined manner can make the debris, under the action of gravity, be more likely to be present in the first area 24 and the second area 25 in the lower vertical direction, that is, to concentrate the debris in the first area 24 and the second area 25 adjacent to the collecting end of the first collecting component 33, and when the first cleaning component 32 and the second cleaning component 34 are cleaning, it is convenient to clean the debris to the collecting end of the first collecting component 33, thereby improving the cleaning efficiency.

[0032] The centrifugal pump water diversion and filtering device of the utility model embodiment is provided with a first filtering component, a first cleaning component 32 and a first collecting component 33. The first cleaning component 32 rotates to clean the debris on the upper end of the first filtering component so as to sweep the debris to the collecting end of the first collecting component 33. The first collecting component 33 is connected to the shell 1, and the collecting end of the first shell 1 faces the lowest point of the first filtering component so that the cleaned debris enters the collecting end of the first collecting component 33 under the action of centrifugal force and gravity, so as to facilitate the subsequent cleaning and collection of the debris in the first collecting component 33.

[0033] In some embodiments, the first filter component includes a first filter screen 21 and a first threaded member 22. The shell 1 is provided with a first mounting groove 12. The first threaded member 22 is arranged in the first mounting groove 12. The first filter screen 21 is at least partially arranged in the first mounting groove 12. The first threaded member 22 passes through the first filter screen 21 and is connected to the shell 1.

[0034] Specifically, Figures 1 to 3 As shown, the first filter screen 21 is arranged obliquely in the up-down direction, the first filter screen 21 is at least partially arranged in the first mounting groove 12, and the first threaded member 22 passes through the first filter component from top to bottom and is threadedly connected to the inner wall surface of the upper end of the first mounting groove 12, thereby fixing the first filter screen 21. The angle of the first filter screen 21 relative to the up-down direction can be adjusted by the first threaded member 22. For example, the angle of the first filter screen 21 relative to the up-down direction can be adjusted by rotating the rotation range of the first threaded member 22, for example, by rotating the first threaded member 22 to change the position of the first threaded member 22 in the up-down direction, thereby changing the angle of the first filter screen 21 relative to the up-down direction.

[0035] Furthermore, the first mounting groove 12 may be annular in shape, and there may be a plurality of first threaded members 22, which may be spaced apart around the circumference of the first filter screen 21, thereby fixing the first filter screen 21 around the circumference of the first filter screen 21 and improving the stability of fixing the first filter screen 21.

[0036] The centrifugal pump water diversion and filtering device of the utility model embodiment is provided with a first threaded member 22 and a first mounting groove 12. The first threaded member 22 passes through the first filter component from top to bottom and is threadedly connected with the inner wall surface of the upper end of the first mounting groove 12, thereby fixing the first filter screen 21, thereby improving the stability of the fixing of the first filter screen 21.

[0037] By rotating the first threaded member 22 to change the position of the first threaded member 22 in the up and down direction, and thereby changing the angle of the first filter 21 relative to the up and down direction, the angle of the first filter 21 can be changed during the installation process to avoid the first filter 21 being arranged parallel to the up and down direction, and to avoid the first filter 21 being arranged orthogonal to the up and down direction.

[0038] Furthermore, one end of the first filter screen 21 has a first preset angle A with the axial direction of the housing 1, and 83°≤A≤88°. A can be 83°, 84°, 85°, 86°, 87°, 88°, so as to avoid the first filter screen 21 being arranged parallel to the left and right directions, thereby avoiding the first filter screen 21 being orthogonal to the up and down directions, which leads to a decrease in the efficiency of debris cleaning, and avoids the first filter component being tilted too much, which leads to the accumulation of debris at the lowest point of the first filter component in the up and down directions, resulting in a decrease in the filtering amount of the first filter component when in use, resulting in too small a water diversion amount, and improving the stability and safety of the centrifugal pump water diversion and filtration device.

[0039] In some embodiments, the first collecting component 33 includes a first collecting tube 331, a first valve 332 and a first collecting box 333. The first collecting tube 331 is connected to the shell 1. One end of the first collecting tube 331 is connected to the shell 1. The other end of the second collecting tube 351 is connected to one end of the first valve 332. The other end of the first valve 332 is connected to the first collecting box 333. The inlet of the first collecting tube 331 faces the lowest point of the first filter net 21 in the up and down direction.

[0040] Specifically, Figures 1 to 3 As shown, the first collecting pipe 331 is connected to the shell 1, and the inlet of the first collecting pipe 331 faces the lowest point of the first filter screen 21 in the up and down direction, so that the debris enters the inlet of the first collecting pipe 331 during cleaning, that is, enters the collecting end of the first collecting component 33, and the inlet of the first valve 332 is connected to the outlet of the first collecting pipe 331, and the outlet of the first valve 332 is connected to the inlet of the first collecting box 333. During the use of the centrifugal pump water diversion and filtering device, the first valve 332 is closed. When the first filter screen 21 is cleaned, the centrifugal pump water diversion and filtering device is in an inspection state. The driving component 31 is turned on to drive the first cleaning component 32 to rotate to clean the debris in the first area 24 and the second area 25 so that the debris enters the inlet of the first collecting pipe 331. At this time, the first valve 332 is opened to facilitate the debris to enter the first collecting box 333 through the first collecting pipe 331.

[0041] At this time, the inlet of the shell 1 can be connected to a clean water source, and the outlet of the shell 1 can be disconnected from the centrifugal pump so that the water in the shell 1 can flow out of the shell 1. The clean water can rinse the debris on the first filter screen 21 to facilitate the debris to enter the first collection box 333.

[0042] The centrifugal pump water diversion and filtering device of the embodiment of the utility model can clean the debris on the first filter screen 21 by providing the first collecting component 33. At this time, there is no need for personnel to manually remove the debris from the housing 1, which facilitates the disposal of the debris.

[0043] Furthermore, the first collecting box 333 and the first valve 332 are detachably connected to the first collecting pipe 331, so that personnel can remove debris at the lowest point of the first filter screen 21 through the first collecting pipe 331, thereby avoiding clogging of the first filter screen 21 after long-term operation, facilitating maintenance of the equipment, and improving the maintainability of the centrifugal pump water diversion and filtration device.

[0044] In some embodiments, the driving component 31 includes a driving member 311 and a driving rod 312, the first cleaning component 32 includes a first cleaning rod 321, the driving member 311 is connected to the shell 1, the driving rod 312 extends into the shell 1, the first cleaning rod 321 is connected to the driving rod 312, and the first cleaning rod 321 is arranged parallel to the first filter 21 in the up and down directions.

[0045] Specifically, Figures 1 to 3 As shown, the driving member 311 is connected to the shell 1, and the output end of the driving member 311 is connected to the driving rod 312. The driving rod 312 penetrates the first filter 21 along the up and down directions. The driving rod 312 is connected to the first cleaning rod 321 to drive the first cleaning rod 321 to rotate on the driving rod 312. The first cleaning rod 321 is a cleaning rod in the prior art.

[0046] The lower end of the first cleaning rod 321 contacts the upper end of the first filter 21, and the first cleaning rod 321 and the first filter 21 are arranged parallel in the up and down directions to avoid interference with the first filter 21 when the first cleaning rod 321 rotates, so as to facilitate the rotation of the first cleaning rod 321 to clean the debris in the first area 24 and the second area 25.

[0047] The driving member 311 may be an existing driving motor or driving device. For example, the driving member 311 may be a servo motor.

[0048] The centrifugal pump water diversion and filtering device of the embodiment of the utility model can clean the debris on the first filter screen 21 by setting the first collecting component 33, without the need for personnel to manually remove the debris on the first filter screen 21 of the shell 1, which is convenient for handling the debris.

[0050] Specifically, Figures 1 to 3As shown, the second filter screen is arranged at the lower end of the first filter screen, that is, after the water enters the housing 1 through the inlet and enters the accommodating chamber 11, it is first filtered through the first filter screen 21 and then filtered through the second filter screen 23. The pore size of the filter pores of the first filter screen 21 is larger than the pore size of the filter pores of the second filter screen 23, thereby performing graded filtration on the water.

[0051] The second cleaning component 34 is connected to the driving rod 312. The second cleaning component 34 rotates under the rotation of the driving rod 312, and then the second cleaning component 34 rotates to clean the debris on the upper end surface of the second filter component, and then sweeps the debris into the second collecting component 35, so as to facilitate cleaning of the debris on the second filter screen 23.

[0052] The centrifugal pump water diversion and filtering device of the utility model embodiment is provided with a second filtering component, a second cleaning component 34 and a second collecting component 35. The second cleaning component 34 rotates to clean the debris on the upper end of the second filtering component so as to sweep the debris to the collecting end of the second collecting component 35. The second collecting component 35 is connected to the shell 1, and the collecting end of the second shell 1 faces the lowest point of the second filtering component so that the cleaned debris enters the collecting end of the second collecting component 35 under the action of centrifugal force and gravity, so as to facilitate the subsequent cleaning and collection of the debris in the second collecting component 35.

[0053] In some embodiments, the second cleaning component 34 includes a second cleaning rod 341 . The second cleaning rod 341 is connected to the driving rod 312 . The second cleaning rod 341 is arranged in parallel with the second filter screen 23 .

[0055] In some embodiments, the second collecting component 35 includes a second collecting pipe 351 and a second valve 352 . The inlet of the second collecting pipe 351 is connected to the shell 1 , and the inlet of the second collecting pipe 351 faces the lowest point of the second filter screen 23 .

[0056] Specifically, Figures 1 to 3As shown, the second collecting pipe 351 is connected to the shell 1, and the inlet of the second collecting pipe 351 faces the lowest point of the second filter screen 23 in the up and down direction, so that the debris enters the inlet of the second collecting pipe 351 during cleaning, that is, enters the collecting end of the second collecting component 35, and the inlet of the second valve 352 is connected to the outlet of the second collecting pipe 351. During the use of the centrifugal pump water diversion and filtering device, the second valve 352 is closed.

[0057] Furthermore, the second collecting component 35 also includes a second collecting box, the outlet of the second valve 352 is connected to the inlet of the second collecting box, and the second collecting box and the water enter the second collecting box. When cleaning the second filter 23, the centrifugal pump water diversion and filtering device is in the maintenance state, the driving component 31 is turned on to drive the first cleaning component 32 to rotate to clean the debris on the second filter 23 so that the debris enters the inlet of the second collecting pipe 351, and the second valve 352 is opened at this time, so that the debris can be discharged into the second collecting box through the second collecting pipe 351. At this time, the inlet of the shell 1 can be connected to the clean water source, and the outlet of the shell 1 can be disconnected from the centrifugal pump so that the water in the shell 1 flows out of the shell 1, and the clean water washes the debris on the second filter 23, so that the debris can enter the second collecting box.

[0058] Furthermore, the second collection box and the second valve 352 are detachably connected to the first collection pipe 331, so that personnel can remove debris at the lowest point of the second filter screen 23 through the second collection pipe 351, thereby avoiding clogging of the second filter screen 23 after long-term operation, facilitating maintenance of the equipment, and improving the maintainability of the centrifugal pump water diversion and filtration device.

[0060] In some embodiments, a second preset angle B is formed between the second filter screen 23 and the axial direction of the housing 1, and 75°≤B≤85°.

[0061] B can be 75°, 76°, 77°, 79°, 80°, 81°, 82°, 83°, 84°, 85°, so as to avoid the second filter screen 23 being arranged in parallel with the left and right directions, thereby avoiding the second filter screen 23 being orthogonal to the up and down directions, which leads to a decrease in the efficiency of debris cleaning, and avoids the second filter component being tilted too much, which leads to the accumulation of debris at the lowest point of the second filter component in the up and down directions, resulting in a decrease in the filtration volume of the second filter component when in use, resulting in too small a water diversion volume, thereby improving the stability and safety of the centrifugal pump water diversion and filtration device.

[0062] Furthermore, B<A, which can be understood as the impurity particles on the first filter 21 are larger, and are convenient to be cleaned under the drive of gravity and the first cleaning rod 321 during cleaning, and the impurity particles on the second filter 23 are smaller than those on the first filter 21, and need to be more tilted to facilitate cleaning of the impurity particles on the second filter 23.

[0063] Furthermore, the first filter screen is provided with a first filter hole, the second filter screen is provided with a second filter hole, and the aperture of the second filter screen is smaller than the aperture of the second filter screen, thereby performing graded filtration on the water to improve the filtration effect.
