[0002] Horizontal centrifugal pump is a kind of high-efficiency equipment widely used in industrial and urban water supply systems. Horizontal centrifugal pump is a pump that places the pump head and drive motor on the same horizontal plane. This layout makes the pump more convenient during installation and maintenance.

[0003] Existing horizontal centrifugal pump barrels are usually equipped with a filter screen at the water inlet to prevent impurities in the water from entering the pump body, thereby achieving the benefit of extending the service life of the pump body;

[0004] However, the filter screen provided in the prior art has a simple structure. Impurities filtered out will directly adhere to the filter screen under the impact of the water flow. These impurities are fixed in position and there is no corresponding cleaning component. This makes the filter screen very easy to be clogged, further increasing the maintenance frequency of the device.

[0005] Therefore, this solution proposes a horizontal high-efficiency centrifugal pump to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a horizontal high-efficiency centrifugal pump to solve the problem that the filter screen provided in the prior art has a single structure, and the filtered impurities will directly adhere to the filter screen under the impact of the water flow. These impurities are fixed in position and there is no corresponding cleaning component, which makes the filter screen very easy to be blocked, further increasing the maintenance frequency of the device.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1 - Figure 6 As shown, the utility model provides a horizontal high-efficiency centrifugal pump, including a base 1 and a connecting plate 5. The top surface of the base 1 is mounted with a centrifugal pump body 2. The centrifugal pump body 2 is provided with a water outlet plate 3 and a water inlet plate 4. The water inlet plate 4 is provided with a filter assembly 6. The filter assembly 6 is mounted with a cleaning assembly 10.

[0030] The cleaning assembly 10 includes a positioning block 103 and a connecting block 101, and the filter assembly 6 includes a sleeve 601;

[0031] The inner cavity of the sleeve 601 is symmetrically installed with positioning blocks 103, and the outer wall of the connecting block 101 is symmetrically installed with a rectangular frame 102. The rectangular frame 102 is slidably installed on the outer wall of the positioning block 103;

[0032] A positioning rod 1016 is respectively installed in the middle of the side where the two positioning blocks 103 are close to each other, and a mounting frame 104 is installed between the two positioning rods 1016. A spring 109 is installed in the inner cavity of the mounting frame 104, and a sliding plate 1017 is installed on the side of the spring 109 away from the inner cavity of the mounting frame 104. A sliding groove 105 is respectively provided on the top and bottom surfaces of the outer wall of the mounting frame 104. A sliding plate 1017 is slidably installed between the two sliding grooves 105. A connecting rod 106 is installed on the side of the sliding plate 1017 away from the spring 109. A stamping frame 107 is installed on the side of the connecting rod 106 away from the sliding plate 1017. The stamping frame 107 is trumpet-shaped;

[0033] The trumpet-shaped design of the punching frame 107 enhances the impact of the water flow on the punching frame 107 during use, facilitating the movement of the punching frame 107.

[0034] Furthermore, the two positioning blocks 103 are used to limit the movement position of the connecting block 101 in the vertical direction;

[0035] Connecting rods 108 are rotatably mounted on the top and bottom surfaces of the sliding plate 1017, and connecting blocks 101 are rotatably mounted on the sides of the two connecting rods 108 away from the sliding plate 1017.

[0036] The connecting block 101 is provided with a mounting slot 1011, a transfer block 1019 is installed in the middle of the mounting slot 1011, two springs 1018 are installed at both ends of the transfer block 1019, and a slider 1014 is installed on the side of the two springs 1018 away from the transfer block 1019;

[0037] The second spring 1018 is used to apply an outward force to the slider 1014, so that the slider 1014 is always in contact with the inner wall of the sleeve 601, and at the same time, the scraper 1015 increases the scraping area of ​​the filter 604.

[0038] A scraper 2 1015 is installed below the side wall of the slider 1014, and a through slot 1012 is opened on one side of the inner cavity of the installation slot 1011;

[0039] A second scraper 1015 is slidably installed in the through groove 1012, and a first scraper 1013 is installed below one side of the outer wall of the connecting block 101;

[0040] A connecting ring 602 is installed on one side of the outer wall of the sleeve 601, a filter screen 604 is installed on one side of the inner cavity of the sleeve 601, and plug rods 603 are symmetrically installed on the side wall of the connecting ring 602. The filter screen 604 contacts the scraper 2 1015, and the filter screen 604 contacts the scraper 1 1013;

[0041] In this embodiment, during use of the device, when the centrifugal pump body 2 starts to work, water flows into the device through the connecting disc 5, the filter assembly 6 and the centrifugal pump body 2;

[0042] At this time, the punching frame 107 will be pushed by the water flow, which in turn drives the connecting rod 106 and the sliding plate 1017 to compress the spring 109. As the punching frame 107 moves, the punching frame 107 drives the connecting block 101 to move in the vertical direction through the connecting rod 108, thereby scraping the filter screen 604.

[0043] When the device stops pumping the water flow, the punching frame 107 loses the water flow punching force, and the punching frame 107, the connecting rod 106, the sliding plate 1017 and the connecting block 101 will be reset;

[0044] It can be seen from this that before and after the device is working, the connecting block 101 can reciprocate in the vertical direction, so that the scraper 1013 on the connecting block 101 can scrape the impurities accumulated on the surface of the filter 604, thereby reducing the accumulation of impurities on the filter 604;

[0045] Furthermore, when the connecting block 101 moves in the vertical direction, the slider 1014 in the mounting groove 1011 is squeezed by the inner wall of the sleeve 601 to expand and contract, thereby adapting to the change in the width of the filter 604 in the vertical direction, and the scraper 2 1015 on the slider 1014 also scrapes the surface of the filter 604, further improving the cleaning efficiency of the cleaning component 10 on the filter 604.

[0046] In a further embodiment, referring to Figure 1 - Figure 6 A contact ring 7 is installed on the side wall of the inner cavity of the centrifugal pump body 2, and a plug hole 8 is symmetrically opened on the contact ring 7. A plug rod 603 is slidably installed in the two plug holes 8 respectively;

[0047] A positioning ring 9 is installed in the inner cavity of the connecting disk 5, and the positioning ring 9 contacts the connecting ring 602;

[0048] In this embodiment, when installing the filter assembly 6, the plug rod 603 is inserted into the plug hole 8, and then the connecting plate 5 is docked with the water inlet plate 4 and positioned with bolts. At this time, the positioning ring 9 and the resistance ring 7 in the connecting plate 5 will clamp and position the connecting ring 602, making it easier to install the filter assembly 6.

[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
