Description

Technical Field

[0001] This utility model belongs to the field of water pump technology, and relates to a vertical water pump, particularly a vertical water pump filtration structure. Background Technology

[0002] Vertical water pumps can be classified as sewage pumps, booster pumps, submersible pumps, etc., and they play an important role in many fields such as industry, construction, and agriculture due to their unique vertical structural design.

[0003] An existing vertical water pump structure, such as the submersible pump head disclosed in the Chinese Patent Database (CN214742392U), includes a volute, an impeller, a pump base, an inlet section, and a bracket. The impeller is disposed inside the volute and connected to the motor shaft. The lower end face of the impeller mates with the upper end face of the pump base. The pump base, inlet section, and bracket are sequentially fixed to the inlet at the bottom of the volute. A filter screen is fitted between the pump base and the inlet section. The upper end of the filter screen extends axially to form an annular connecting part. A ring of blades is welded and fixed to the outer wall of the connecting part at uniform intervals. The outer ends of the blades are movably connected and fitted into a positioning ring. The top surface of the inlet section and the bottom surface of the pump base have corresponding mounting steps. Both the upper and lower ends of the positioning ring abut against the mounting steps.

[0004] In the aforementioned pump head, the inlet section is fixed to the pump base by a ring of bolts, and the filter screen is clamped between the pump base and the inlet section. In actual use, when a lot of dirt adheres to the inner wall of the filter screen and is difficult to clean, it is necessary to first unscrew the bolts to separate the inlet section from the pump base, then remove the filter screen from the inlet section for cleaning, reinstall the filter screen after cleaning and adjust its position, and finally screw the bolts back in to reposition the filter screen. The entire operation involves many steps and is cumbersome, making it inconvenient to disassemble and assemble the filter screen. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a vertical water pump filtration structure that facilitates the assembly and disassembly of the filter cartridge.

[0006] The objective of this utility model can be achieved through the following technical solution: A vertical water pump filtration structure includes a cylindrical base and a filter cylinder vertically arranged inside the base. The upper side wall of the base is bent inward to form a ring-shaped connecting seat, and the upper side wall of the filter cylinder is bent outward to form a ring-shaped outer flange. The connecting seat has a threaded hole, and an external threaded ring is vertically formed on the top wall of the outer flange, and the external threaded ring is threaded into the threaded hole. A baffle is provided on the outer side of the external threaded ring. There are two baffles symmetrically arranged along the center of the external threaded ring. One end of the baffle is detachably fixed to the base by a screw, and the other end of the baffle is a horizontally arranged limiting plate, which is located directly below the outer flange to limit the downward movement distance of the filter cylinder.

[0007] During actual installation, the pump body is mounted on the top wall of the base; during use, water enters the pump body after being filtered through the filter cartridge.

[0008] A baffle is installed to limit the downward movement of the filter cartridge, effectively preventing the filter cartridge from loosening, moving downward, and falling off during water pump operation.

[0009] When using this application, only two baffles need to be removed and installed, and then the filter cartridge can be screwed out or screwed in to achieve filter cartridge disassembly and assembly. Compared with the existing technology of disassembling and assembling the base to achieve filter cartridge disassembly and assembly, this solution significantly reduces the operation steps and has the advantages of convenient and easy filter cartridge disassembly and assembly.

[0010] In the above-mentioned vertical water pump filter structure, an annular step is provided on the outer wall of the external threaded ring, and the annular step and the external threaded ring are coaxially arranged. The annular step is composed of an annular step side wall and a step bottom wall. The step side wall is provided with an external thread that matches the above-mentioned threaded hole. The step bottom wall presses on the bottom wall of the connecting seat to restrict the upward movement of the filter cartridge. This not only facilitates the disassembly and assembly of the filter cartridge, but also eliminates the need for additional structures to restrict the upward movement of the filter cartridge, thus simplifying the structure.

[0011] In the above-mentioned vertical water pump filter structure, an annular mounting groove is provided on the stepped side wall, and a sealing ring is provided in the mounting groove. The outer wall of the sealing ring contacts and seals with the wall of the threaded hole to enhance the sealing strength between the external threaded ring and the base, so that water can completely pass through the filter cartridge into the water pump body.

[0012] In the aforementioned vertical water pump filter structure, the end of the baffle away from the outward-facing edge is a horizontally positioned mounting plate, which presses against the bottom wall of the connecting seat. The mounting plate has a vertically opening through hole, and the connecting seat has a positioning hole. The number of screws, positioning holes, and through holes are equal, and their positions correspond one-to-one. The screw shank passes through the corresponding through hole and screws into the corresponding positioning hole, with the screw head pressing against the underside of the corresponding mounting plate. With this design, during actual installation, simply loosening the screws and rotating the baffle releases the restriction on the filter cartridge, eliminating the need to completely remove the baffle and further simplifying the operation, thus facilitating filter cartridge assembly and disassembly.

[0013] In the above-mentioned vertical water pump filter structure, the middle part of the baffle is a vertically arranged connecting piece, which is located between the limiting piece and the mounting piece, and the two ends of the connecting piece are respectively connected to the limiting piece and the mounting piece.

[0014] In the above-mentioned vertical water pump filtration structure, the baffle is an integral structure.

[0015] Compared with existing technologies, this vertical water pump filtration structure has the following advantages: 1. When using this application, it is only necessary to remove and install two baffles, and then screw out or screw in the filter cartridge to realize the filter cartridge disassembly and assembly. Compared with the existing technology of disassembling and installing the base to realize the filter cartridge disassembly and assembly, this solution significantly reduces the operation steps and has the advantages of convenient and easy disassembly and assembly of the filter cartridge.

[0016] 2. The baffle plate is detachably fixed to the connecting seat by means of screws, through holes and positioning holes, and the screw axis is set vertically. In actual operation, you only need to loosen the screw and rotate the baffle plate to release the limit on the filter cartridge. This eliminates the need to completely remove the baffle plate, further simplifying the operation steps and making it convenient to disassemble and assemble the filter cartridge.

Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1 and Figure 2 As shown, this vertical water pump filtration structure includes a cylindrical base 1 and a filter cartridge 2 vertically arranged inside the base 1, and the filter cartridge and the base 1 are coaxially arranged.

[0024] in, The upper side wall of the base 1 is bent inward to form a ring-shaped connecting seat 1a, and the connecting seat 1a and the base 1 are coaxially arranged.

[0025] The top of the filter cartridge 2 is open, and the bottom of the filter cartridge 2 is closed. A ring of filter holes 2a is formed on the side wall of the filter cartridge 2. The upper side wall of the filter cartridge 2 is bent outward to form an annular flange 2b, and the flange 2b is coaxial with the filter cartridge 2.

[0026] Specifically, such as Figures 2 to 4 As shown, the inner hole of the connecting seat 1a is a threaded hole, and an external threaded ring 2c is vertically formed on the top wall of the outer flange 2b. The external threaded ring 2c and the filter cartridge 2 are coaxially arranged, and the external threaded ring 2c is threaded into the threaded hole. A baffle 3 is provided on the outer side of the external threaded ring 2c, and the baffle 3 is located inside the base 1. There are two baffles 3, which are symmetrically arranged along the center of the external threaded ring 2c. One end of the baffle 3 is detachably fixed to the base 1 by a screw 4, and the other end of the baffle 3 is a horizontally arranged limiting piece 3a. The limiting piece 3a is located directly below the outer flange 2b to limit the downward movement distance of the filter cartridge 2, thereby preventing the external threaded ring 2c from dislodging from the threaded hole.

[0027] In actual installation, the pump body 5 is mounted on the top wall of the base 1; during use, water enters the pump body 5 after being filtered by the filter cartridge 2. A baffle 3 is provided to limit the downward movement of the filter cartridge 2, effectively preventing the filter cartridge 2 from loosening, moving downwards, or falling off during pump operation.

[0028] When using this application, it is only necessary to remove and install the two baffles 3, and then screw out or screw in the filter cartridge 2 to realize the removal and installation of the filter cartridge 2. Compared with the existing technology of removing and installing the base 1 to realize the removal and installation of the filter cartridge 2, this solution has significantly reduced the operation steps and has the advantages of convenient and easy removal and installation of the filter cartridge 2.

[0029] In this embodiment, The structure of baffle 3 is as follows: baffle 3 is a one-piece structure, and baffle 3 is roughly "Z" shaped. For example... Figure 1 As shown, the end of the baffle 3 furthest from the outer flange 2b is a horizontally arranged mounting piece 3b, and the middle part of the baffle 3 is a vertically arranged connecting piece 3c. The connecting piece 3c is located between the limiting piece 3a and the mounting piece 3b, and the two ends of the connecting piece 3c are respectively connected to the limiting piece 3a and the mounting piece 3b.

[0030] like Figure 3 As shown, the baffle 3 is installed as follows: the mounting plate 3b presses against the bottom wall of the connecting seat 1a. A through hole is vertically opened on the mounting plate 3b, and a positioning hole is provided on the connecting seat 1a. The number of screws 4, positioning holes, and through holes are the same, and their positions correspond one-to-one. The shank of screw 4 passes through the corresponding through hole and is screwed into the corresponding positioning hole, with the head of screw 4 pressing against the underside of the corresponding mounting plate 3b. With this design, during actual installation, only the screws 4 need to be loosened, and then the baffle 3 rotated to release the restriction on the filter cartridge 2. This eliminates the need to completely remove the baffle 3, further simplifying the operation and facilitating the installation and removal of the filter cartridge 2.

[0031] like Figure 2 and Figure 4As shown, an annular step 2d is formed on the outer wall of the external threaded ring 2c, and the annular step 2d and the external threaded ring 2c are coaxially arranged. The annular step 2d is composed of annular step sidewalls 2d1 and step bottom walls 2d2, and the step sidewalls 2d1 and step bottom walls 2d2 are arranged perpendicularly. The step sidewall 2d1 has an external thread that matches the aforementioned threaded hole, and the step bottom wall 2d2 presses against the bottom wall of the connecting seat 1a to restrict the upward movement of the filter cartridge 2. This facilitates the assembly and disassembly of the filter cartridge 2 and eliminates the need for additional structures to restrict its upward movement, thus simplifying the structure. Further, an annular mounting groove is formed on the step sidewall 2d1, and the mounting groove and the annular step 2d are coaxially arranged. A sealing ring 6 is provided in the mounting groove, and the outer wall of the sealing ring 6 contacts and seals the threaded hole wall to strengthen the seal between the external threaded ring 2c and the base 1, allowing water to completely pass through the filter cartridge 2 into the pump body 5.

[0032] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
