Description

Technical Field

[0001] This utility model relates to the field of mixed flow pump technology, specifically a mixed flow pump that is easy to install and disassemble. Background Technology

[0002] A mixed-flow pump is a type of pump that falls between a centrifugal pump and an axial-flow pump. The specific speed of a mixed-flow pump is higher than that of a centrifugal pump but lower than that of an axial-flow pump, typically between 300 and 500 RPM. Its head is higher than that of an axial-flow pump, but its flow rate is lower than that of an axial-flow pump but higher than that of a centrifugal pump.

[0003] In existing mixed-flow pump equipment, the base is usually welded to the pump body or connected by multiple sets of bolts. When replacement or maintenance is required, either the pump cannot be disassembled and the entire unit needs to be replaced, or disassembly and assembly require a lot of time and manpower to remove and install the various mounting screws on the pump body. This reduces the efficiency of pump disassembly and assembly and brings many inconveniences to the disassembly, assembly, maintenance and use of mixed-flow pumps. At the same time, in order to ensure working efficiency, existing mixed-flow pumps have a filter screen installed at the inlet pipe. However, due to the high content of impurities such as silt in some water flows, the filter screen is prone to clogging in a short period of time. The only way to reduce filter clogging is for the mixed-flow pump to be replaced by the operator. This method is relatively troublesome, and the constant replacement of the filter screen will increase the operating cost of the mixed-flow pump. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a mixed-flow pump that is easy to install and disassemble, including a pump body 1 and a connecting base 2. A control ring 3 is rotatably connected to the outer surface of the pump body 1, and an external gear ring 4 is provided on the lower side of the control ring 3. A connecting through hole is opened inside the connecting base 2, and an L-shaped connecting rod 5 is rotatably connected inside the connecting through hole. A connecting gear 6 is provided at the upper end of the L-shaped connecting rod 5, and the connecting gear 6 meshes with the external gear ring 4. The pump body 1 is set on the upper surface of the connecting base 2, and an inlet pipe 7 is provided on the outer surface of the pump body 1. The pipe 7 has a support frame 8 inside, a limit bearing in the middle of the support frame 8, a support shaft 9 inside the limit bearing, a turbine blade 10 on the outer surface of the support shaft 9, a filter screen 11 inside the inlet pipe 7, the support shaft 9 is rotatably connected to the inside of the filter screen 11, an installation ring 12 on the outer surface of the support shaft 9, a cleaning scraper 13 on the outer surface of the installation ring 12, the cleaning scraper 13 abuts against the outer surface of the filter screen 11, and a discharge port 14 is opened at the lower end of the inlet pipe 7.

[0022] Specifically, by rotating the control ring 3, the external gear ring 4 is driven to rotate, which in turn drives the connecting gear 6 and the L-shaped connecting rod 5 to deflect at a certain angle so that they are misaligned with the installation position, thereby realizing the quick installation and disassembly of the mixed flow pump. When the external water flows into the inlet pipe 7, the filter screen 11 filters the impurities in the water flow. At the same time, the water flow impacts the turbine blades 10, which drives the support shaft 9 to rotate, thereby driving the cleaning scraper 13 to rotate and scrape the impurities filtered by the filter screen 11 into the discharge pipe 14 to clean the filter screen 11, prevent the filter screen 11 from being replaced frequently, and reduce the cost of use.

[0023] Please refer to Figure 1. The outer surface of the control ring 3 is provided with a toggle plate 15, and the upper surface of the connecting base 2 is provided with a limit piece 16. There are two limit pieces 16, which are located on both sides of the toggle plate 15.

[0024] Specifically, the toggle plate 15 makes it easier to rotate the control ring 3, and the two limit plates 16 can effectively limit the rotation angle of the control ring 3 to prevent excessive rotation of the control ring 3.

[0025] Please refer to Figure 1. The upper surface of the control ring 3 has two positioning holes 17. An inverted L-shaped control plate 18 is slidably connected inside the connecting base 2. A positioning post is provided on the inner side of the inverted L-shaped control plate 18. The position of the positioning post is adapted to the position of the positioning hole 17.

[0026] Specifically, by sliding the inverted L-shaped control plate 18, the positioning pin is locked into different positioning holes 17, fixing the position of the control ring 3, thereby preventing the mixed flow pump from rotating and detaching itself after installation.

[0027] Please see Figure 1 There are several L-shaped connecting rods 5, which are evenly distributed inside the connecting base 2.

[0028] Specifically, the multiple sets of L-shaped connecting rods 5 effectively ensure the stability of the mixed flow pump installation.

[0029] Please refer to 3-5. A sealing cap 19 is threadedly connected to the side of the discharge port 14 away from the liquid inlet pipe 7. The discharge port 14 is located to the side and below the filter screen 11.

[0030] Specifically, by removing and installing the sealing cover 19, the filtered impurities stored in the discharge port 14 can be cleaned quickly.

[0031] Please refer to 1. A drain pipe 20 is provided on the outer surface of the pump body 1.

[0032] Specifically, the normal drainage operation of the mixed flow pump is completed through the drain pipe 20.

[0033] During use, move the pump body 1 and connecting base 2 to the corresponding mounting base. Simultaneously, insert the L-shaped connecting rod 5 into the corresponding mounting hole. Then, slide the L-shaped control plate 18 upwards, disengaging the positioning pin from the corresponding positioning hole 17. Rotate the control ring 3 via the actuating plate 15, causing the external gear ring 4 to rotate. This causes the connecting gear 6 and L-shaped connecting rod 5 to deflect at a certain angle, misaligning them with the installation position. Then, release the L-shaped control plate, allowing the positioning pin to engage with another positioning hole 17, thus achieving rapid installation of the mixed-flow pump. For disassembly, slide the L-shaped control plate 18 upwards again, disengaging the positioning pin from the corresponding positioning hole 17. Rotate the control ring 3 via the reverse actuating plate 15, causing the external gear ring 4 to rotate. This causes the connecting gear 6 and L-shaped connecting rod 5 to deflect at a certain angle, aligning them with the installation position. Pump body 1 can be quickly disassembled. During normal use, when external water flows into the inlet pipe 7, the filter screen 11 filters impurities in the water flow. At the same time, the water flow impacts the turbine blades 10, causing the support shaft 9 to rotate, which in turn drives the cleaning scraper 13 to rotate, scraping the impurities filtered by the filter screen 11 into the discharge pipe 14 to clean the filter screen 11, preventing frequent replacement of the filter screen 11 and reducing operating costs. After a period of use, the external water flow valve is closed, and the sealing cover 19 is removed from the discharge pipe 14 to discharge the impurities stored in the discharge pipe 14. This allows the easily installed and disassembled mixed-flow pump to achieve the effect of easy and quick installation and disassembly, and also avoids the frequent replacement of the filter screen 11, reducing operating costs.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
