Description

Technical Field

[0001] This application relates to the technical field of centrifugal pumps, and particularly relates to a liquid supply centrifugal pump with intelligent impurity separation. Background Art

[0002] A centrifugal pump works by using the rotation of an impeller to cause the water to undergo centrifugal motion. The pump shaft drives the impeller and water to rotate at a high speed. The water undergoes centrifugal motion and is thrown towards the outer edge of the impeller, flowing into the pressure water pipeline of the water pump through the flow channel of the volute pump casing. During the process of pumping water, in order to avoid the solid particle impurities in the water body from wearing the inner wall of the pump body and the impeller inside the pump body, and at the same time avoid the impurities from forming blockages inside the pump body and extend the service life of the pump body, an interception net is usually set up to intercept the solid impurities entering the pump body. Currently, when cleaning the interception net, the filter screen is usually cleaned by backwashing with the pump body. However, before cleaning, it is necessary to first stop the machine and disconnect the water inlet pipe of the pump body from the external water pipe to expose the interception net, and then carry out the cleaning operation. Stopping the machine will affect the water supply and the progress of the subsequent processes. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention accordingly.

[0026] Example 1

[0027] A liquid supply centrifugal pump for intelligently separating impurities, as Figures 1 - 6 shown, includes a base 1, a pump body 2, a filter frame 3, and a pipe 1 4; the pump body 2 is bolted to the base 1; the filter frame 3 is bolted to the base 1; the water inlet of the pump body 2 is communicated with the filter frame 3; the right part of the filter frame 3 is communicated with the pipe 1 4;

[0028] It also includes a power unit, a rotating disc 5, a connecting rod 6, a filter plate 7, a driving motor 13, a connecting frame 1 14, and a lower sealing plate 15; two rotating discs 5 are rotatably connected to the filter frame 3; the power unit is connected to the base 1; four connecting rods 6 arranged in an annular array are connected between the two rotating discs 5; a filter plate 7 is connected between adjacent two connecting rods 6, and a filter screen is arranged in the middle of each filter plate 7; all the connecting rods 6 and the filter plates 7 are in contact with the inner wall of the filter frame 3; a connecting frame 1 14 is fixedly connected to the filter frame 3; a lower sealing plate 15 is rotatably connected to the connecting frame 1 14; a driving motor 13 is bolted to the connecting frame 1 14; the output shaft of the driving motor 13 is fixedly connected to the lower sealing plate 15.

[0029] In order to monitor the clogging condition of the filter plate 7, a water flowmeter is arranged at the water inlet of the pump body 2.

[0030] The power unit includes a motor 8, a gear 9, and a toothed ring 16; the motor 8 is bolted to the base 1; the output shaft of the motor 8 is fixedly connected with the gear 9; a toothed ring 16 is fixedly connected to one of the rotating discs 5; the gear 9 meshes with the toothed ring 16.

[0031] In order to facilitate the replacement of the filter plate 7, the rotating disc 5 and the filter frame 3 are detachably connected; the rotating disc 5, the connecting rod 6, and the filter plate 7 are detachably connected to each other.

[0032] During use, connect the right part of the first pipeline 4 to the water extraction pipe, and connect the water outlet at the upper part of the pump body 2 to the drain pipe. Then, control the pump body 2 to start for pumping operation. The pumped water successively passes through the first pipeline 4, the filter frame 3, the water inlet of the pump body 2, and the water outlet at the upper part of the pump body 2, and then is discharged into the designated position through the drain pipe. When the water passes through the filter frame 3, the rightmost filter plate 7 in the filter frame 3 will intercept the impurities in the water, avoiding the abrasion of the inner wall of the pump body 2 and the impeller inside the pump body 2 by solid particle impurities, and preventing the impurities from forming blockages inside the pump body 2, thus extending the service life of the pump body 2. A water flow meter is arranged at the water inlet pipe of the pump body 2 to monitor the water flow in the water inlet pipe in real time. When the monitored water flow significantly decreases to be lower than the normal delivery volume (indicating that the filter plate 7 is severely blocked), without shutting down the pump body 2, with the front-to-back view as the reference, control the motor 8 to drive the toothed ring 16 to rotate clockwise by 90 degrees through the gear 9. The toothed ring 16 drives the rotating disk 5, the connecting rod 6, and the filter plate 7 to rotate by 90 degrees, so that the filter plate 7 originally used to intercept impurities rotates downward, and the clean filter plate 7 originally at the upper part rotates towards the first pipeline 4, thereby intercepting the impurities. In this way, without shutting down the pump body 2, the blocked filter plate 7 can be replaced, so as not to affect the water delivery and avoid affecting the subsequent processes.

[0033] After the pump body 2 finishes pumping water, control the driving motor 13 to drive the lower sealing plate 15 to rotate downward, so that the lower sealing plate 15 is separated from the filter frame 3, and the lower opening of the filter frame 3 is exposed. Then, the staff uses a high-pressure water gun to wash the lower filter plate 7 through the upper opening of the filter frame 3, washing down the impurities stuck on the filter mesh of the filter plate 7. And a collection box is placed below the filter frame 3 in advance, and the washed debris will fall downward out of the filter frame 3 and be collected in the collection box. After cleaning the lowermost filter plate 7, control the motor 8 to drive the toothed ring 16 to rotate clockwise by 90 degrees through the gear 9. The toothed ring 16 drives the rotating disk 5, the connecting rod 6, and the filter plate 7 to rotate by 90 degrees, so that the filter plate 7 used to intercept impurities rotates downward. Then, use the high-pressure water gun to wash the lower filter plate 7 through the upper opening of the filter frame 3 again. After cleaning, control the lower sealing plate 15 to rotate back to its original position to re-seal the lower opening of the filter frame 3.

[0034] Embodiment 2

[0035] On the basis of Embodiment 1, as Figure 1 and Figures 4 - 6 shown, it further includes a water cylinder 31, a third pipeline 32, and an electromagnetic valve 33. A water cylinder 31 is fixedly connected to the filter frame 3, and the filter frame 3 is communicated with the water cylinder 31. A third pipeline 32 is communicated between the water cylinder 31 and the water outlet of the pump body 2. An electromagnetic valve 33 is arranged on the third pipeline 32.

[0036] It further includes a fixing rod 21, a second pipeline 22, a baffle 23, a retaining frame 24 and a flushing plate 25; the fixing rod 21 is fixedly connected to the base 1; the fixing rod 21 penetrates through the two rotating disks 5 and is rotatably connected thereto; the middle part of the fixing rod 21 is fixedly connected with the second pipeline 22; the upper part of the second pipeline 22 is fixedly connected with the baffle 23, and the second pipeline 22 penetrates through the baffle 23; the baffle 23 contacts the two connecting rods 6 above; the lower part of the second pipeline 22 is fixedly connected with the retaining frame 24; the retaining frame 24 contacts the two connecting rods 6 below; the second pipeline 22 penetrates through the retaining frame 24; the lower part of the retaining frame 24 is fixedly connected with the flushing plate 25, and a plurality of through holes are formed in the flushing plate 25.

[0037] It further includes a rotating shaft 41, blades 42 and a brush plate 43; the rotating shaft 41 is rotatably connected in the second pipeline 22 through a connecting plate, and the rotating shaft 41 penetrates through the flushing plate 25 and is rotatably connected thereto; the blades 42 are fixedly connected to the rotating shaft 41; the brush plate 43 is fixedly connected to the lower part of the rotating shaft 41, and bristles are arranged on the brush plate 43.

[0038] In order to enable all parts of the filter screen in the middle of the filter plate 7 to be cleaned when the brush plate 43 rotates, the filter screen in the middle of the filter plate 7 is set to be circular and its diameter is smaller than the length of the brush plate 43.

[0039] When the pump water volume is very large, the filter plate 7 needs to rotate multiple times, resulting in the filter plate 7 that originally intercepted debris rotating to the right of the water inlet of the pump body 2. At this time, the impurities intercepted by the filter plate 7 face the water inlet of the pump body 2, and the flowing water will carry the impurities into the pump body 2, causing damage to the pump body 2. Therefore, there are a water cylinder 31, a second pipeline 22, a baffle 23 and a retaining frame 24, the baffle 23 and the retaining frame 24; when the filter plate 7 originally used to intercept impurities rotates downward, control the driving motor 13 to drive the lower sealing plate 15 to rotate downward, so that the lower sealing plate 15 is separated from the filter frame 3, exposing the lower opening of the filter frame 3. During the rotation of the lower sealing plate 15, the lower opening of the filter frame 3 is isolated from the water flow area through the two connecting rods 6 below and the retaining frame 24, preventing the water flowing through the filter frame 3 from flowing out through the lower opening of the filter frame 3. Then, without shutting down the pump body 2, open the solenoid valve 33 on the third pipeline 32. In this way, part of the water after intercepting impurities can be discharged into the water cylinder 31 through the third pipeline 32. During the process of the water being discharged into the water cylinder 31 through the third pipeline 32, the upper opening of the filter frame 3 is isolated from the water flow area through the two connecting rods 6 above and the baffle 23, preventing the water flowing through the filter frame 3 from affecting the water flowing out of the water cylinder 31 from entering the second pipeline 22, that is, the water discharged into the water cylinder 31 flows into the baffle 23 through the upper opening of the filter frame 3, then flows into the space formed by the retaining frame 24 and the flushing plate 25 through the second pipeline 22, and finally flows out from the through holes of the flushing plate 25 to flush the lower filter plate 7. After cleaning, control the lower sealing plate 15 to rotate back to its original position to block the lower opening of the filter frame 3. In this way, when the filter plate 7 rotates downward, the water conveyed by the pump body 2 is used to intelligently clean the filter plate 7, preventing the filter plate 7 with impurities from rotating to the right of the water inlet of the pump body 2, and further preventing the flowing water from carrying impurities into the pump body 2 and causing damage to the pump body 2. In addition, the water conveyed by the pump body 2 is used to intelligently clean the filter plate 7, eliminating the need for manual cleaning of the filter plate 7 with a high-pressure water gun, saving manpower.

[0040] In addition, when water flows through the second pipeline 22, the water flow drives the blade 42 to rotate. The blade 42 drives the brush plate 43 to rotate through the rotating shaft 41. The lower ends of the bristles on the brush plate 43 pass through the filter mesh on the filter plate 7. When the brush plate 43 rotates, the bristles on the brush plate 43 push the impurities stuck on the filter mesh of the filter plate 7 downward, ensuring the cleaning effect of the impurities on the filter mesh of the filter plate 7.

[0041] Embodiment 3

[0042] Based on Embodiment 2, as Figure 1 、 Figure 2 and 4 - Figure 6As shown in the figure, it further includes an electric push rod II 10, a connecting frame II 11 and an upper sealing plate 12; two electric push rods II 10 are connected to the water cylinder 31, and the telescopic ends of all the electric push rods II 10 penetrate through the water cylinder 31; the telescopic ends of all the electric push rods II 10 are commonly fixedly connected to a connecting frame II 11; the upper sealing plate 12 is welded to the connecting frame II 11; the upper sealing plate 12 is slidably connected to the filter frame 3.

[0043] In order to accelerate the flow rate of water flowing out of the through holes of the flushing plate 25, the through holes of the flushing plate 25 are set in an inverted conical shape.

[0044] In order to enhance the sealing effect and prevent water leakage, sealing strips are provided at the joints of the rotating disc 5, the upper sealing plate 12 and the lower sealing plate 15 with the filter frame 3.

[0045] After the pumping operation is completed, impurities are intercepted on the filter plate 7 to the left of the pipeline I 4. It is necessary to rotate the filter plate 7 downward and then clean it. However, at this time, since the pump body 2 has stopped, the water of the pump body 2 cannot be used to clean the filter plate 7. It is necessary to remove the water cylinder 31 from the upper part of the filter frame 3, and then the staff uses a high-pressure water gun to clean the filter plate 7, which is a cumbersome and time-consuming process; therefore, an upper sealing plate 12 is provided. In the initial state, the upper sealing plate 12 is located inside the water cylinder 31 and does not affect the cleaning operation of the filter plate 7 during the operation of the pump body 2. Before the pump body 2 is about to be shut down, control the electric push rod II 10 to drive the connecting frame II 11 and the upper sealing plate 12 to move downward, so that the upper sealing plate 12 moves downward into the filter frame 3, blocking the upper opening of the filter frame 3. Then, open the solenoid valve 33 on the pipeline III 32, so that the water outlet pipe of the pump body 2 is connected to the water cylinder 31 through the pipeline III 32. In this way, part of the water after intercepting impurities can be discharged into the water cylinder 31 through the pipeline III 32. The upper opening of the filter frame 3 is blocked by the upper sealing plate 12, and the discharged water can be temporarily stored in the water cylinder 31. After a certain amount of water is discharged (a water level sensor is provided in the water cylinder 31 to monitor the water volume), shut down the solenoid valve 33; then after the pumping operation is completed and the pump body 2 is closed, control the motor 8 to drive the toothed ring 16 to rotate clockwise by 90 degrees through the gear 9. The toothed ring 16 drives the rotating disc 5, the connecting rod 6 and the filter plate 7 to rotate by 90 degrees, so that the filter plate 7 for intercepting impurities rotates downward. Then control the electric push rod II 10 to drive the connecting frame II 11 and the upper sealing plate 12 to move upward, so that the upper sealing plate 12 moves upward and separates from the filter frame 3, making the upper opening of the filter frame 3 communicate with the water cylinder 31. In this way, the water in the water cylinder 31 can flow downward through the upper opening of the filter frame 3 onto the baffle 23, and then flow into the space formed by the retaining frame 24 and the flushing plate 25 through the pipeline II 22, and finally flow out of the through holes of the flushing plate 25 to wash the lower filter plate 7, without the need for the staff to use a high-pressure water gun for cleaning operation after the pumping operation is completed.

[0046] However, after the pump body 2 is closed, the water pressure of the flushing water flowing out of the water cylinder 31 is low, that is, after the flushing water flows out of the through holes of the flushing plate 25, the speed is slow, and the flushing effect on the filter plate 7 is poor; therefore, the electric push rod two 10 can be controlled to drive the connecting frame two 11 and the upper sealing plate 12 to move downward, so that the upper sealing plate 12 re-enters the filter frame 3 and slides downward in the filter frame 3. During the sliding process, the upper sealing plate 12 presses the flushing water in the filter frame 3 downward, so that the downward flow speed of the water becomes faster, and finally the flow speed of the flushing water flowing out of the through holes of the flushing plate 25 becomes faster, so as to ensure the flushing effect on the filter plate 7.

[0047] Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through the present disclosure that various changes or modifications can be made to the present invention without departing from the principle and spirit scope of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, rather than to limit the present invention, but the scope of protection is defined by the content of the claims.
