Description

Technical Field

[0001] The utility model relates to the technical field of magnetic pumps, in particular to a magnetic pump. Background Art

[0002] A magnetic drive pump, also known as a magnetic drive pump, consists of an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. When the motor rotates the outer magnetic rotor, the magnetic field penetrates the air gap and non-magnetic materials, driving the inner magnetic rotor connected to the impeller to rotate synchronously. This achieves contactless, synchronous power transmission and transforms a leak-prone dynamic seal into a zero-leakage static seal. Efficient and pure fluid delivery is crucial in the application of magnetic drive pumps.

[0003] Traditional filtration mechanisms often use fixed filter screens or filter particles with fixed gap sizes, making them unable to adapt to changes in fluid pressure and flow. This results in excessive gaps between filter particles under high pressure or high flow conditions, allowing some impurities to pass through, thus affecting filtration effectiveness.

[0004] Therefore, in order to solve the shortcomings of the above problems, a magnetic pump is proposed. Summary of the Invention

[0005] The utility model overcomes the deficiencies of the prior art and provides a magnetic pump.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a magnetic pump comprising: a pump body, a filter mechanism disposed at the output end of the pump body, and a plurality of filter particles disposed in the filter mechanism;

[0007] The filtering mechanism includes: a connecting frame, a mounting frame arranged on one side of the connecting frame, a first filter plate arranged at one end of the connecting frame, a second filter plate arranged at one end of the mounting frame, and a spring arranged on an inner wall of one side of the mounting frame;

[0008] One side of the connecting frame is fixedly connected to one side of the mounting frame, the connecting frame is threadedly connected to the output end of the pump body, one end of the spring is fixedly connected to the inner wall of one side of the mounting frame, and the other end of the spring is fixedly connected to the extrusion plate.

[0009] In a preferred embodiment of the present invention, a plurality of through slots are formed on one side of the extrusion plate.

[0010] In a preferred embodiment of the present invention, a plurality of sliding blocks are fixedly connected to the circumferential outer wall of the extrusion plate.

[0012] In a preferred embodiment of the present invention, a plurality of sliding blocks are respectively located in a plurality of sliding grooves and are slidably connected.

[0013] In a preferred embodiment of the present invention, the circumferential outer wall of the extrusion plate is tightly fitted with the circumferential inner wall of the installation frame.

[0014] In a preferred embodiment of the present invention, the first filter plate is clamped to the connection frame, and the second filter plate is clamped to a side of the installation frame away from the connection frame.

[0015] In a preferred embodiment of the present invention, one side of the first filter plate is fixedly connected to a fixing rod, and one side of the second filter plate is fixedly connected to a connecting rod.

[0016] In a preferred embodiment of the present invention, the circumferential outer wall of the connecting rod is threadedly connected to the circumferential inner wall of the fixing rod, and the fixing rod passes through the extrusion plate.

[0017] In a preferred embodiment of the present invention, a plurality of the filter particles are located between the second filter plate and the extrusion plate.

[0018] The present invention solves the defects in the background technology and has the following beneficial effects:

[0019] (1) The utility model provides a magnetic pump, which can dynamically adjust the gap between the filter particles through the arrangement of the extrusion plate and the spring. The elastic force of the spring enables the extrusion plate to automatically adjust its position according to the change of the filter pressure, thereby effectively avoiding the problem of poor filtering effect caused by excessive gaps between the filter particles.

[0020] (2) The present invention provides a magnetic pump, which makes it easy and quick to disassemble and assemble the filter plates and filter particles through the first filter plate and the second filter plate, and through the threaded connection of the fixing rod and the connecting rod, and the first filter plate and the second filter plate can limit the filter particles.

[0021] (3) The present invention provides a magnetic pump, which not only optimizes the arrangement and distribution of the filter particles but also enhances the overall filtering efficiency by providing a through groove on one side of the extrusion plate and arranging structures such as a spring and a slider in the installation frame. At the same time, the arrangement of the slider and the slide groove can make the movement of the extrusion plate smoother, further improving the stability and durability of the filtering mechanism.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0028] like Figure 3 As shown, a magnetic pump comprises: a pump body 1, a filter mechanism 2 arranged at the output end of the pump body 1, and a plurality of filter particles 212 arranged in the filter mechanism 2;

[0029] like Figure 1-Figure 2 As shown, the filter mechanism 2 includes: a connecting frame 201, a mounting frame 202 provided on one side of the connecting frame 201, a first filter plate 203 provided on one end of the connecting frame 201, a second filter plate 206 provided on one end of the mounting frame 202, and a spring 209 provided on the inner wall of one side of the mounting frame 202;

[0030] One side of the connecting frame 201 is fixedly connected to one side of the mounting frame 202. The connecting frame 201 is threadedly connected to the output end of the pump body 1. One end of the spring 209 is fixedly connected to the inner wall of one side of the mounting frame 202. The other end of the spring 209 is fixedly connected to the extrusion plate 207.

[0031] A plurality of through grooves 208 are provided on one side of the extrusion plate 207, a plurality of sliders 210 are fixedly connected to the circumferential outer wall of the extrusion plate 207, a plurality of slide grooves 211 are provided on the circumferential inner wall of the mounting frame 202, and the plurality of sliders 210 are respectively located in the plurality of slide grooves 211 and slidably connected, and the circumferential outer wall of the extrusion plate 207 is tightly fitted with the circumferential inner wall of the mounting frame 202.

[0032] It should be noted that the filter mechanism 2 is configured to filter the liquid output from the pump body 1. The spring 209 and the extrusion plate 207 allow the filter mechanism 2 to automatically adjust the gap between the filter particles 212 according to changes in fluid pressure, thereby ensuring optimal filtering performance under various operating conditions. The extrusion plate 207 is slidably connected to the slide 211 of the mounting frame 202 via the slider 210, ensuring the stability of the extrusion plate 207 during movement. The tight fit between the extrusion plate 207 and the mounting frame 202 effectively prevents fluid leakage and ensures the normal operation of the magnetic pump. The connection frame 201 is threadedly connected to the output end of the pump body 1, making assembly and disassembly of the filter mechanism 2 simple and quick. Furthermore, the snap-fit design of the first filter plate 203 and the second filter plate 206, as well as the placement of the filter particles 212 between the extrusion plate 207 and the second filter plate 206, provide significant convenience for users and reduce maintenance costs and time.

[0033] like Figure 1 As shown, the first filter plate 203 is clamped with the connecting frame 201, and the second filter plate 206 is clamped with the side of the mounting frame 202 away from the connecting frame 201. One side of the first filter plate 203 is fixedly connected to a fixing rod 204, and one side of the second filter plate 206 is fixedly connected to a connecting rod 205. The circumferential outer wall of the connecting rod 205 is threadedly connected to the circumferential inner wall of the fixing rod 204. The fixing rod 204 passes through the extrusion plate 207, and a number of filter particles 212 are located between the second filter plate 206 and the extrusion plate 207.

[0034] It should be noted that the snap-fit design between the first filter plate 203 and the connecting frame 201, and between the second filter plate 206 and the mounting frame 202, facilitates assembly and disassembly of the first and second filter plates 203, 206. The threaded connection between the fixing rod 204 and the connecting rod 205 forms a stable connection between the first and second filter plates 203, 206, thereby ensuring a stable distribution of the filter particles 212 between the extrusion plate 207 and the second filter plate 206. The provision of the fixing rod 204 penetrating the extrusion plate 207 allows the extrusion plate 207, under the action of the spring 209, to more evenly compress the filter particles 212, thereby improving filtration efficiency. Furthermore, since the filter particles 212 are tightly compressed together, the gaps between them are effectively reduced, further enhancing the process.

[0035] When the present invention is in use, a number of filter particles 212 are placed in the installation frame 202, and then the connecting rod 205 is threadedly connected to the fixing rod 204, so that the second filter plate 206 is clamped with the installation frame 202. Due to the elastic force of the spring 209, the spring 209 squeezes the extrusion plate 207, so that the gaps between the filter particles 212 are tightly compressed together. When the extrusion plate 207 moves, the extrusion plate 207 drives the slider 210 to slide in the slide groove 211. After the filter mechanism 2 is installed, the connecting frame 201 is threadedly connected to the output end of the pump body 1, so that the circumferential outer wall of the installation frame 202 is tightly fitted with the circumferential inner wall of the output end of the pump body 1. When the pump body 1 is operating, the liquid is filtered through the first filter plate 203, the through groove 208, the number of filter particles 212 and the second filter plate 206 in sequence.

[0036] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
