Description

Technical Field

[0001] The utility model relates to the technical field of self-priming pumps, in particular to an anti-clogging vertical self-priming pump. Background Art

[0002] Self-priming pumps, as efficient and convenient fluid conveying equipment, have been widely used in various fields, including industry, agriculture, construction, and daily life. Their core advantage lies in their ability to self-prime water without the need for external drainage, significantly simplifying the pump's installation and use. The operating principle of a self-priming pump is primarily based on centrifugal force. The high-speed rotation of the impeller causes the fluid to gain energy and flow out of the pump body, while simultaneously creating a vacuum at the pump inlet, drawing in new fluid.

[0003] Existing vertical self-priming pumps face a major problem during use. Specifically, since the water source often contains impurities, these impurities enter the pump body with the water flow and easily adhere to the surface of the impeller, affecting the rotation speed of the impeller, thereby reducing the overall efficiency and life of the pump.

[0004] To address this issue, existing technical solutions typically involve connecting a filter device to the front end of the self-priming pump's input to filter out impurities in the water and prevent clogging. For example, Chinese Patent Publication No. "CN112901562A" discloses a vertical self-priming pump with a filter function. However, this filter structure can only filter a single water channel. When the inner filter screen needs to be cleaned, the pump must be shut down and the filter screen removed, which not only affects its efficiency but also increases the complexity and cost of maintenance.

[0005] Therefore, in order to further improve the ease of use of the existing anti-clogging self-priming pump, we propose an anti-clogging vertical self-priming pump. Summary of the Invention

[0006] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose an anti-clogging vertical self-priming pump.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] An anti-clogging vertical self-priming pump is designed, comprising: a pump body and a filter unit connected to the output end of the pump body;

[0009] The filter unit includes an input main pipe, two branch pipes and a manifold, wherein the two branch pipes are connected between the input main pipe and the manifold;

[0010] A filter assembly is installed on the branch pipe, a one-way assembly is provided on the inner side of the branch pipe, and a three-way valve is provided in the input main pipe.

[0011] Further, the filtering component includes a filter;

[0012] The middle portion of the branch pipe is provided with a truncation section, and the two ends of the filter are connected and fixed to the two ends of the truncation section via flanges and fasteners.

[0013] Furthermore, the filter includes a flow guide portion and a mounting portion, and the mounting portion is connected to the lower side of the flow guide portion;

[0014] Both ends of the guide portion are fixedly connected with flanges, and the inner side of the guide portion is provided with a bending step, and the inner side of the mounting portion is provided with a filter component.

[0015] Furthermore, the filter component includes a filter cartridge inserted into the inner side of the mounting portion, the top of the filter cartridge is open, the opening abuts against the bending step, and a pipe cover is threadedly connected to the open end of the mounting portion.

[0016] Furthermore, the one-way component is installed at the opening of the branch pipe located at the cut-off section;

[0017] The one-way component includes a mounting plate with a water hole. A plug rod is movably inserted into the middle of the mounting plate through a spring. The other end of the plug rod is fixedly connected to a valve plate, and the valve plate covers the water hole.

[0018] Furthermore, the mounting plate is threadedly connected to the opening of the truncation section, and the diameter of the valve plate is smaller than the diameter of the mounting plate.

[0019] Furthermore, the input main pipe and the manifold are both T-shaped pipes, and the manifold is detachably connected to the input end of the pump body.

In this state, the filter component of the branch can be disassembled and cleaned without stopping the machine, which greatly improves the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-4 This is an embodiment of the present utility model, which discloses an anti-clogging vertical self-priming pump, which includes a pump body 1 and a filter unit 2 connected to the output end of the pump body 1. The specific structure and principle of the pump body 1 have been disclosed in the prior art and will not be repeated here.

[0028] Specifically, the filter unit 2 in this embodiment includes an input main pipe 21, two branch pipes 22 and a manifold 23, and the two branch pipes 22 are connected between the input main pipe 21 and the manifold 23;

[0029] A filter assembly 3 is installed on the branch pipe 22 , and a one-way assembly 4 is also provided on the inner side of the branch pipe 22 .

[0030] In some embodiments, the filter assembly 3 of the present invention includes a filter 31;

[0031] The middle part of the branch pipe 22 has a truncation section, and the two ends of the filter 31 are connected and fixed to the two ends of the truncation section by flanges 32 and fasteners, that is, flanges 32 are installed at both ends of the filter 31 and the two openings of the truncation section described in this embodiment, wherein the fasteners described in this embodiment are preferably configured as bolt and nut assemblies, and the two adjacent flanges 32 are connected by bolts and nuts to achieve the fixation of the filter 31.

[0032] Based on the above embodiment, the filter 31 in this embodiment includes a flow guide portion 311 and a mounting portion 312. The mounting portion 312 is connected to the lower side of the flow guide portion 311. The flow guide portion 311 in this embodiment is obliquely connected to the lower side of the mounting portion 312 and forms a Y-shaped structure with the mounting portion 312. The flow guide portion 311 is used to convey water, and the mounting portion 312 is used to install the filter component.

[0033] The two ends of the guide portion 311 are fixedly connected with flanges 32 , and the inner side of the guide portion 311 has a bending step 313 , and the inner side of the mounting portion 312 is provided with a filter component.

[0034] The filtration unit 314 of the present invention is to be connected with the filter cartridge 314 of the fixing portion 312, and the filter cartridge 314 is connected with the filter cartridge 314 of the fixing portion 312. The filtration unit 314 of the present invention is to be connected with the filter cartridge 314 of the fixing portion 312, and the filter cartridge 314 is connected with the filter cartridge 314 of the fixing portion 312.

[0035] It should be noted that the one-way component 4 in this embodiment is installed at the opening of the branch pipe 22 located at the truncated section. Specifically, in this embodiment, the one-way component 4 is installed at the opening on the rear side along the water cooling direction, and the one-way component 4 is conductive in the water flow direction and blocked in the reverse direction.

[0036] The one-way component 4 includes a mounting plate 41 with a water hole 42. A rod 44 is movably inserted in the middle of the mounting plate 41 through a spring 43. The other end of the rod 44 is fixedly connected to a valve plate 45. The valve plate 45 covers the water hole 42. During operation, water flows through the water hole 42, and the pressure of the water flow pushes the valve plate 45 to move, thereby forming a passage. When there is no water flow, the valve plate 45 is reset to cover the water hole 42 under the pull of the spring 43 to close the water path.

[0037] Of course, in order to achieve convenient assembly and maintenance of the entire one-way component 4, the mounting plate 41 in this embodiment is threadedly connected to the opening of the truncated section. In order to ensure that the water flow can flow normally, the diameter of the valve plate 45 in this embodiment is smaller than the diameter of the mounting plate 41. In this way, a flow channel can be formed between the valve plate 45 and the inner wall of the branch pipe 22 to ensure the flow of water.

[0038] Furthermore, the one-way component 4 provided in this embodiment is to form the two branches 22 into independent water supply pipes. Of course, in order to realize the separate control of the two independent water supply pipes, the input main pipe 21 and the manifold 23 in this embodiment are both T-shaped pipes, and a three-way valve 5 is also provided in the input main pipe 21. The three-way valve 5 is connected to the three-pipe connection of the input main pipe 21, and is used to switch and conduct the water flow of one of the branches 22. The manifold 23 is detachably connected to the input end of the pump body 1. Preferably, the manifold 23 described in this embodiment can be detachably connected by threaded connection, thereby improving the convenience of assembly.

[0039] That is to say, in this embodiment, the three-way valve 5 is used to switch the water path of one of the branches 22 to be connected, while the water path of the other branch 22 is cut off. Since the branch 22 is internally provided with a one-way component 4, the connected branch 22 will not cause water path interference to the other cut-off branch 22, thereby ensuring that the other branch 22 is in a water-free state. In this state, the filter component 3 of the branch 22 can be disassembled and cleaned without stopping the machine, which greatly improves the convenience of operation.

[0040] In summary, the present invention adopts the design of two branches 22, and sets a filter component 3 inside the branch pipe 22 to filter impurities in the water, so as to avoid the problem of impurities entering the self-priming pump and causing blockage. Secondly, the design of the one-way component 4 and the three-way valve 5 can form two independent water supply pipes. When the water channel of one branch pipe 22 is connected, the other branch pipe 22 is in a water-free state. In this state, the filter component 3 of the branch pipe 22 can be disassembled and cleaned without stopping the machine, which greatly improves the convenience of operation.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
