Description

Technical Field

[0001] The present application relates to the technical field of centrifugal pumps, and in particular to a liquid supply centrifugal pump capable of intelligently separating impurities. Background Art

[0002] A centrifugal pump works by using the rotation of the impeller to cause water to move centrifugally. The pump shaft drives the impeller and water to rotate at high speed. The water moves centrifugally and is thrown to the outer edge of the impeller, flowing into the water pressure pipe of the pump through the flow channel of the volute pump casing. During the pumping process, in order to prevent solid particle impurities in the water from wearing the inner wall of the pump body and the impeller inside the pump body, and to prevent impurities from clogging the pump body and extending the service life of the pump body, an interception net is usually set to intercept solid impurities entering the pump body. Currently, when cleaning the interception net, the filter screen is usually backwashed and cleaned with the pump body. However, before cleaning, the pump needs to be shut down to disconnect the water inlet pipe of the pump body from the external water pipe to expose the interception net, and then the cleaning operation can be carried out.

DETAILED DESCRIPTION

[0025] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0026] Example 1

[0027] A liquid supply centrifugal pump for intelligently separating impurities, such as Figure 1-Figure 6 As shown, it includes a base 1, a pump body 2, a filter frame 3 and a pipe 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 connected to the filter frame 3; the right part of the filter frame 3 is connected to the pipe 4;

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

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

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

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

[0032] When in use, connect the right part of pipe 14 with the water pumping pipe, connect the water outlet on the upper part of pump body 2 with the drain pipe, then control pump body 2 to start and perform water pumping operation, the pumped water passes through pipe 14, filter frame 3, water inlet of pump body 2 and water outlet on the upper part of pump body 2 in sequence, and then is discharged into the designated position through the drain pipe; when water passes through filter frame 3, the rightmost filter plate 7 in filter frame 3 will intercept impurities in the water, so as to prevent solid particle impurities from causing wear to the inner wall of pump body 2 and the impeller inside pump body 2, and prevent impurities from forming blockage inside pump body 2, thereby extending the service life of pump body 2; a water flow meter is arranged at the water inlet pipe of pump body 2 for real-time monitoring of the flow of water in the water inlet pipe. When the monitored water flow rate is significantly reduced to below the normal delivery volume (indicating that the filter plate 7 is seriously blocked), without shutting down the pump body 2, the motor 8 is controlled to rotate ninety degrees clockwise through the gear 9 transmission gear ring 16, and the gear ring 16 drives the rotating disk 5, the connecting rod 6 and the filter plate 7 to rotate ninety degrees, so that the filter plate 7 originally used to intercept impurities rotates downward, and the filter plate 7 originally on the upper and clean rotates toward the pipe 4, thereby intercepting impurities. In this way, the blocked filter plate 7 can be replaced without shutting down the pump body 2, so as not to affect the water delivery, thereby avoiding affecting the subsequent processes.

[0033] After the pump body 2 finishes pumping water, the control driving motor 13 drives the lower sealing plate 15 to rotate downward, so that the lower sealing plate 15 is separated from the filter frame 3, so that the lower opening of the filter frame 3 is exposed; then, the staff uses a high-pressure water gun to rinse the filter plate 7 below through the upper opening of the filter frame 3, and the impurities stuck on the filter screen of the filter plate 7 are rinsed down, and a collection frame is prevented in advance below the filter frame 3, and the rinsed debris will fall down out of the filter frame 3 and fall into the collection frame for collection; after cleaning the bottom filter plate 7, the control motor 8 drives the gear ring 16 through the gear 9 to rotate ninety degrees clockwise, and the gear ring 16 drives the rotating disk 5, the connecting rod 6 and the filter plate 7 to rotate ninety degrees, so that the filter plate 7 used to intercept impurities rotates downward, and then the high-pressure water gun is used to rinse the filter plate 7 below through the upper opening of the filter frame 3; after cleaning, the control lower sealing plate 15 is rotated and reset to re-block the lower opening of the filter frame 3.

[0034] Example 2

[0035] On the basis of Example 1, Figure 1 and Figure 4-Figure 6 As shown, it also includes a water cylinder 31, a pipe three 32 and a solenoid valve 33; the water cylinder 31 is fixedly connected to the filter frame 3, and the filter frame 3 is connected to the water cylinder 31; the pipe three 32 is connected between the water cylinder 31 and the water outlet of the pump body 2; and the solenoid valve 33 is arranged on the pipe three 32.

[0036] It also includes a fixed rod 21, a second pipe 22, a baffle 23, a baffle frame 24 and a flushing plate 25; the fixed rod 21 is fixedly connected to the base 1; the fixed rod 21 passes through the two rotating disks 5 and is rotatably connected thereto; the middle part of the fixed rod 21 is fixedly connected to the second pipe 22; the baffle 23 is fixedly connected to the upper part of the second pipe 22, and the second pipe 22 passes through the baffle 23; the baffle 23 is in contact with the two connecting rods 6 above; the baffle frame 24 is fixedly connected to the lower part of the second pipe 22; the baffle frame 24 is in contact with the two connecting rods 6 below; the second pipe 22 passes through the baffle frame 24; the flushing plate 25 is fixedly connected to the lower part of the baffle frame 24, and a plurality of through holes are opened on the flushing plate 25.

[0037] It also includes a rotating shaft 41, blades 42 and a brush plate 43; the rotating shaft 41 is rotatably connected to the pipe 22 through a connecting plate, and the rotating shaft 41 passes 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 the brush plate 43 is provided with bristles.

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

[0039] When the amount of water pumped is large, the filter plate 7 needs to be rotated several times, causing the filter plate 7 that originally intercepted the debris to rotate 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 bring the impurities into the pump body 2, causing damage to the pump body 2; therefore, a water cylinder 31, a pipe 22, a baffle 23 and a baffle frame 24 are provided, and the baffle 23 and the baffle frame 24; when the filter plate 7 originally used to intercept impurities rotates downward, the control driving motor 13 drives the lower sealing plate 15 to rotate downward The lower sealing plate 15 is moved to separate from the filter frame 3, so that the lower opening of the filter frame 3 is exposed. 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 and the baffle 24 below, so as to prevent the water flowing in the filter frame 3 from flowing out through the lower opening of the filter frame 3. Then, without shutting down the pump body 2, the solenoid valve 33 on the pipe 3 32 is opened, so that part of the water after intercepting impurities can be discharged into the water cylinder 31 through the pipe 3 32. The water passes through the pipe 3 In the process of the water discharged into the water cylinder 31, the upper opening of the filter frame 3 is isolated from the water circulation area by the two connecting rods 6 and the baffle plate 23 above, so as to prevent the water circulating in the filter frame 3 from affecting the water flowing out of the water cylinder 31 and entering the pipe 22, that is, the water discharged into the water cylinder 31 flows into the baffle plate 23 through the upper opening of the filter frame 3, and then flows into the space formed by the baffle frame 24 and the flushing plate 25 through the pipe 22, and finally flows out from the through hole of the flushing plate 25 to flush the filter plate 7 below. After cleaning, the control The lower sealing plate 15 is rotated and reset to block the lower opening of the filter frame 3; in this way, when the filter plate 7 is rotated downward, the water delivered by the pump body 2 is used to intelligently clean the filter plate 7 to prevent the filter plate 7 with impurities from rotating to the right of the water inlet of the pump body 2, thereby preventing the flowing water from bringing impurities into the pump body 2 and causing damage to the pump body 2; in addition, the water delivered by the pump body 2 is used to intelligently clean the filter plate 7, and there is no need to manually clean the filter plate 7 with a high-pressure water gun, thus saving manpower.

[0040] In addition, when water flows in the pipe 22, the water flow drives the blade 42 to rotate, and 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 screen on the filter plate 7. When the brush plate 43 rotates, the bristles on the brush plate 43 push down the impurities stuck on the filter screen on the filter plate 7, thereby ensuring the cleaning effect of the impurities in the filter screen on the filter plate 7.

[0041] Example 3

[0042] On the basis of Example 2, Figure 1 , Figure 2 and 4 - Figure 6As shown, it also includes an electric push rod 2 10, a connecting frame 2 11 and an upper sealing plate 12; two electric push rods 2 10 are connected to the water cylinder 31, and the telescopic ends of all the electric push rods 2 10 pass through the water cylinder 31; the telescopic ends of all the electric push rods 2 10 are commonly fixed to the connecting frame 2 11; the upper sealing plate 12 is welded to the connecting frame 2 11; the upper sealing plate 12 is slidably connected to the filter frame 3.

[0043] In order to speed up the flow of water out of the through hole of the flushing plate 25, the through hole of the flushing plate 25 is configured to be in an inverted cone shape.

[0044] In order to enhance the sealing effect and prevent water leakage, sealing strips are provided at the connection points between the rotating disk 5 , the upper sealing plate 12 , the lower sealing plate 15 and the filter frame 3 .

[0045] After the pumping operation is completed, impurities are intercepted on the filter plate 7 located on the left side of the pipe 1 4, and the filter plate 7 needs to be turned downward and then cleaned. However, since the pump body 2 has been stopped at this time, the filter plate 7 cannot be cleaned with water from the pump body 2. The water cylinder 31 needs to be removed from the upper part of the filter frame 3, and the staff uses a high-pressure water gun to clean the filter plate 7. The process is cumbersome and time-consuming. Therefore, an upper sealing plate 12 is provided. In the initial state, the upper sealing plate 12 is located in the water cylinder 31 and does not affect the During the operation of the pump body 2, the filter plate 7 is cleaned. Before shutting down the pump body 2, the electric push rod 2 10 is controlled to drive the connecting frame 2 11 and the upper sealing plate 12 to move downward, so that the upper sealing plate 12 moves down into the filter frame 3, so that the upper opening of the filter frame 3 is blocked, and then the solenoid valve 33 on the pipe 3 32 is opened, so that the water outlet pipe of the pump body 2 is connected with the water cylinder 31 through the pipe 3 32. In this way, part of the water after intercepting impurities can be discharged into the water cylinder 31 through the pipe 3 32, and the filter frame 3 is connected to the water cylinder 31. The lower opening 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 amount of water), the solenoid valve 33 is closed; then after the pumping operation is completed and the pump body 2 is closed, the control motor 8 drives the gear ring 16 through the gear 9 to rotate ninety degrees clockwise, and the gear ring 16 drives the rotating disk 5, the connecting rod 6 and the filter plate 7 to rotate ninety degrees, so that the filter plate 7 for intercepting impurities rotates downward, and then the electric push rod 10 is controlled to drive the connecting frame 1 1 and the upper sealing plate 12 move upward, so that the upper sealing plate 12 moves upward and separates from the filter frame 3, so that the upper opening of the filter frame 3 is connected with the water cylinder 31, so that the water in the water cylinder 31 can flow downward to the baffle plate 23 through the upper opening of the filter frame 3, and then flow into the space formed by the baffle frame 24 and the flushing plate 25 through the pipe 22, and finally flow out from the through hole of the flushing plate 25 to flush the filter plate 7 below, 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, the flushing water flows out from the through hole of the flushing plate 25 at a slow speed, and the flushing effect on the filter plate 7 is poor; therefore, the electric push rod 2 10 can be controlled to drive the connecting frame 2 11 and the upper sealed plate 12 to move downward, so that the upper sealed plate 12 re-enters the filter frame 3 and slides downward in the filter frame 3. During the sliding process, the upper sealed plate 12 presses the flushing water in the filter frame 3 downward, so that the water flows downward faster, and finally the flushing water flows out of the through hole of the flushing plate 25 faster, thereby ensuring the flushing effect on the filter plate 7.

[0047] Although the present invention is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principle and spirit of the present invention defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the present invention, but the scope of protection is limited by the content of the claims.
