Description

Technical Field

[0001] This utility model relates to the field of magnetic pump technology, and in particular to an elliptical shaft driven magnetic pump. Background Technology

[0002] Magnetic drive pumps, as an advanced type of pump that achieves contactless torque transmission through magnetic coupling technology, operate on the principle of precisely driving the inner and outer magnetic rotors to rotate synchronously by penetrating a specially designed isolation sleeve via a magnetic field. This completely avoids the leakage risk caused by wear of moving parts in traditional mechanical seals. This groundbreaking design makes it an ideal choice for conveying hazardous media such as toxic, flammable, and highly corrosive substances in fields with extremely high requirements for media safety, such as chemical, pharmaceutical, and environmental protection industries.

[0003] However, some magnetic pump products currently on the market have significant shortcomings. On the one hand, they lack effective protective structures, making the pump body susceptible to collisions or impacts from solid particles in complex industrial environments, leading to increased equipment damage rates and maintenance costs. On the other hand, they generate considerable noise during operation, which not only adversely affects the physical and mental health of operators but also fails to meet the requirements of modern factories for low-noise production environments. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an elliptical shaft driven magnetic pump.

[0005] The technical solution is as follows: an elliptical shaft driven magnetic pump, including a base plate, a sliding plate, a U-shaped insert, a return spring a, and a pump body. The sliding plate is slidably mounted on the top of the base plate, and a U-shaped insert is inserted into the left side of the sliding plate. The U-shaped insert can also be inserted into the left side of the base plate to limit and fix the sliding plate. Two return springs a are connected between the U-shaped insert and the sliding plate. The pump body is placed on the top of the sliding plate. The pump body also includes a connecting component, a protective component, and a heat dissipation component. A connecting component is provided between the sliding plate and the pump body to fix the pump body on the top of the sliding plate. A protective component is provided on the top of the base plate to protect the pump body. A heat dissipation component is provided between the protective component and the base plate to dissipate heat from the pump body.

The mounting frame is fixedly connected to the top center of the sliding plate. Trapezoidal limit blocks are slidably arranged on both the front and rear sides of the mounting frame. A connecting plate is fixedly connected to the side of the two trapezoidal limit blocks that are far apart from each other. Two return springs b are connected between the connecting plate and the mounting frame. A support is fixedly connected to the bottom center of the pump body. The support can be inserted into the mounting frame and is limited and fixed by the two trapezoidal limit blocks.

[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] Example: Elliptical shaft driven magnetic pump, such as Figures 1-5 As shown, the system includes a base plate 1, a sliding plate 2, a U-shaped insert 21, a return spring a22, and a pump body 23. The sliding plate 2 is slidably mounted on the top of the base plate 1. The U-shaped insert 21 is inserted into the left side of the sliding plate 2. The U-shaped insert 21 can also be inserted into the left side of the base plate 1 to limit and fix the sliding plate 2. Two return springs a22 are connected between the U-shaped insert 21 and the sliding plate 2. The pump body 23 is placed on the top of the sliding plate 2. The system also includes a connecting assembly, a protective assembly, and a heat dissipation assembly. A connecting assembly is provided between the sliding plate 2 and the pump body 23 to fix the pump body 23 on the top of the sliding plate 2. A protective assembly is provided on the top of the base plate 1 to protect the pump body 23. A heat dissipation assembly is provided between the protective assembly and the base plate 1 to dissipate heat from the pump body 23.

[0021] like Figure 2 and Figure 3 As shown, the connecting assembly includes a mounting frame 31, trapezoidal limiting blocks 32, a connecting plate 33, a return spring b34, and a support 35. The mounting frame 31 is welded and fixed to the top center of the sliding plate 2. Trapezoidal limiting blocks 32 are slidably arranged on both the front and rear sides of the mounting frame 31. The sides of the two trapezoidal limiting blocks 32 that are close to each other are both inclined. The sides of the two trapezoidal limiting blocks 32 that are far from each other are both welded and fixed to the connecting plate 33. Two return springs b34 are connected between the connecting plate 33 and the mounting frame 31. The support 35 is welded and fixed to the bottom center of the pump body 23. The support 35 can be inserted into the mounting frame 31 and is limited and fixed by the two trapezoidal limiting blocks 32, thereby fixing the pump body 23 to the top of the sliding plate 2.

[0022] like Figure 1 and Figure 4 As shown, the protective assembly includes a protective shell 41, a sound insulation plate 42, and a sealing plate 43. The protective shell 41 is welded and fixed to the top of the base plate 1. The sound insulation plate 42 is fixed to the inner wall of the protective shell 41 by bolts. The sealing plate 43 is welded and fixed to the top left side of the sliding plate 2. The sealing plate 43 is used to seal the gap between the left side of the pump body 23 and the protective shell 4 and the sliding plate 2 to prevent external debris from entering the interior of the protective shell 4.

[0023] like Figure 4 As shown, the heat dissipation assembly includes a cooling box 51, a U-shaped connecting pipe 52, a micro water pump 53, a water outlet pipe 54, and a heat exchange pipe 55. The cooling box 51 is welded and fixed to the top right side of the base plate 1. The U-shaped connecting pipe 52 is symmetrically connected to the front and back of the right side of the cooling box 51. Micro water pumps 53 are installed on both the front and back sides of the upper part of the cooling box 51. The top of each of the two micro water pumps 53 is connected to a water outlet pipe 54. The front and back sides of the right panel of the protective shell 41 are fixedly connected to the heat exchange pipe 55. The bent parts of the two heat exchange pipes 55 are located inside the protective shell 41. The upper and lower ends of the two heat exchange pipes 55 penetrate the sound insulation plate 42 and the protective shell 41, and are connected to the adjacent water outlet pipe 54 and U-shaped connecting pipe 52.

[0024] During installation, the worker pulls the U-shaped insert 21 upwards, detaching it from the base plate 1. At this point, the worker can slide the sliding plate 2 to the left, causing the mounting frame 31 to move to the left to the outside of the protective housing 41. Then, the worker takes the pump body 23 and inserts the support 35 at the bottom of the pump body 23 downwards into the mounting frame 31. During insertion, the front and rear sides of the bottom of the support 35 press against the inclined surfaces of the two trapezoidal limiting blocks 32. As the support 35 continues to press down, the two trapezoidal limiting blocks 32 are pushed away from each other, thereby stretching the return spring b34 through the connecting plate 33. When the support 35 is pressed down to the lowest point inside the mounting frame 31, the bottom of the support 35 releases pressure from the trapezoidal limiting blocks 32. Under the reset action of the return spring b34, the connecting plate 33 drives the two trapezoidal limiting blocks 32 to move closer to each other, thereby fixing the support 35 in the mounting frame 31 and fixing the pump body 23 to the top of the sliding plate 2. Then, the sliding plate 2 is pushed to slide to the right to reset. After releasing the U-shaped plug 21, under the reset action of the return spring a22, the U-shaped plug 21 is reinserted into the left side of the base plate 1 to fix the sliding plate 2. In this way, the pump body 23 moves into the protective shell 41. During the use of the pump body 23, the protective shell 41 can protect the pump body 23 and prevent the pump body 23 from being damaged by external forces. At the same time, the sound insulation plate 42 can absorb the noise generated by the pump body 23 during operation and reduce the transmission of noise. Meanwhile, the operator starts the micro water pump 53, which draws out the cooling water in the cooling tank 51 and pumps it into the heat exchange tube 55 through the outlet pipe 54, and finally returns to the cooling tank 51 through the U-shaped connecting pipe 52. When the cooling water passes through the heat exchange tube 55, it absorbs the heat generated by the pump body 23 during operation and accumulates inside the protective shell 41. Then it returns to the cooling box 51 to release the heat, thereby achieving the heat dissipation effect of the pump body 23 and making the pump body 23 more stable during operation.

[0025] like Figure 5 As shown, it also includes an impeller 61 and a drive shaft 62. Both the impeller 61 and the drive shaft 62 are components that make up the pump body 23. The cross-section of the drive shaft 62 is elliptical, and the mating part between the impeller 61 and the drive shaft 62 is also elliptical, so as to realize elliptical transmission between the drive shaft 62 and the impeller 61.

[0026] By changing the traditional circular design of the mating part of the impeller 61 and the drive shaft 62 to an elliptical shape, and changing the key drive to an elliptical drive, the stability of the structure is enhanced.

[0027] like Figure 2 As shown, it also includes a placement seat 7, which is welded and fixed to the top right side of the sliding plate 2.

[0028] The placement seat 7 facilitates positioning the pump body 23 during installation and also supports the right side of the pump body 23 after installation.

[0029] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
