Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation blower technology, and in particular to a heat dissipation device for a magnetic levitation blower. Background Technology

[0002] A magnetic levitation blower is a high-speed turbine machine that uses an active magnetic levitation bearing. Its rotor is completely suspended in the air during operation, achieving contactless operation. During operation, the motor windings, magnetic bearing coils, and frequency converter power module generate a significant amount of heat. To ensure long-term stable operation, an efficient cooling system is essential. Currently, the mainstream cooling method involves installing ventilation holes or fins on the equipment casing, combined with an internal air duct design, utilizing forced air cooling or natural convection to remove heat from the machine.

[0003] In practical industrial applications, the working environment of magnetic levitation blowers is often quite complex. For example, in sewage treatment plants or cement plants, the air is usually filled with a large amount of dust, willow catkins, oily particles, and other impurities. To ensure heat dissipation efficiency while preventing contamination of internal precision components, existing equipment typically installs dust filters on the air intake side of the heat dissipation vents. However, once the filter becomes clogged, the heat dissipation performance drops sharply. Therefore, to ensure the heat dissipation effect of the magnetic levitation blower, there is an urgent need for a magnetic levitation blower with an easy-to-clean filter. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heat dissipation device for magnetic levitation blowers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat dissipation device for a magnetic levitation blower includes a magnetic levitation blower with multiple heat dissipation holes. A dustproof frame is installed on the outer side of the heat dissipation holes via an opening and closing shaft, and a dustproof net is installed on the dustproof frame. Double-layer scrapers are movably installed on both sides of the dustproof net, and one end of the double-layer scrapers is connected by a female pull plate. A locking post is movably installed on the female pull plate by the preload of a spring, and a corresponding locking groove is provided on the magnetic levitation blower to fit the locking post.

[0007] In addition, a preferred structure is that the dustproof frame has a single groove on one side near the opening and closing shaft and a double groove on the other side.

[0008] Furthermore, in a preferred configuration, one scraper of the double-layer scraper is longer than the scraper of the other side and extends out from the single groove, with the extended portion connected to the sub-pull plate.

[0009] In addition, in a preferred structure, the other end of each of the double-layer scrapers passes through the double grooves and is connected to the mother pull plate. A guide rod is fixedly provided on one end of the double-layer scraper near the mother pull plate, and a guide groove is adapted to fit the guide rod between the double grooves.

[0010] In addition, a preferred structure is that the mother pull plate has a through hole, the locking pin is adapted to move within the through hole, and a handle is fixedly provided at one end of the outer side of the locking pin.

[0011] Furthermore, in a preferred configuration, spring cavities are provided on both sides of the through hole on the female pull plate, and springs connected to the handle are installed in each spring cavity.

[0012] The beneficial effects of this utility model are as follows: heat dissipation during the blowing process can be achieved through the heat dissipation holes on the magnetic levitation blower; the mutual locking between the clamping post and the clamping slot makes it easy for users to clean the dust on the dustproof net, avoiding the impact of dust accumulation on the surface of the dustproof net on the heat dissipation efficiency, and ensuring the heat dissipation effect of the magnetic levitation blower.

Detailed Implementation

[0021] 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.

[0022] Reference Figure 1-7 A heat dissipation device for a magnetic levitation blower includes a magnetic levitation blower 1. The blower 1 has multiple heat dissipation holes 11. A dustproof frame 2 is installed on the outer side of each heat dissipation hole 11 via an opening and closing shaft 22, and a dustproof net 21 is installed on the dustproof frame 2. Double-layer scrapers 3 are movably installed on both sides of the dustproof net 21. One end of each scraper 3 is connected by a female pull plate 33. A locking post 34 is movably installed on the female pull plate 33 by the preload of a spring 333, and a corresponding locking groove 12 is provided on the magnetic levitation blower 1 to fit the locking post 34.

[0023] The dustproof frame 2 has a single groove 23 on one side near the opening and closing shaft 22 and a double groove 24 on the other side. The scraper on one side of the double-layer scraper 3 is longer than the scraper on the other side and extends out from the single groove 23, and the extended part is connected to the pull plate 31.

[0024] The other end of each of the double-layer scrapers 3 passes through the double grooves 24 and is connected to the mother pull plate 33. A guide rod 32 is fixedly installed on one end of the double-layer scraper 3 near the mother pull plate 33, and guide grooves are adapted to fit the guide rods 32 between the double grooves 24. The guide rods 32 and guide grooves enable the double-layer scraper 3 to be guided and moved. This is prior art and will not be described in detail.

[0025] The female pull plate 33 has a through hole 331, and the locking pin 34 is adapted to move within the through hole 331. A handle 35 is fixedly provided on one end of the outer side of the locking pin 34. The handle 35 makes it easy to pull the locking pin 34.

[0026] The female pull plate 33 has spring cavities 332 on both sides of the through hole 331, and each spring cavity 332 is equipped with a spring 333 connected to the handle 35. The spring 333 is a high-strength anti-vibration spring in the prior art to ensure that it still has sufficient elastic preload under extreme vibration environment. This is prior art, so it will not be described in detail.

[0027] In this embodiment, air blowing is achieved by a magnetic levitation blower 1, which has an internal heat dissipation mechanism, and heat is discharged from the heat dissipation holes 11. This is prior art, so it will not be described in detail.

[0028] Furthermore, when cleaning the dustproof net 21, simply pull the locking post 34 outward with the handle 35 to release the mutual jamming between the locking post 34 and the locking groove 12, and then the dustproof frame 2 can be rotated open by the opening and closing shaft 22.

[0029] Then, the user only needs to grasp the male pull plate 31 and the female pull plate 33 and move them up and down repeatedly to drive the double-layer scraper 3 to scrape off the dust on the dustproof net 21.

[0030] After cleaning, pull the locking post 34 outward again using handle 35, and rotate the dustproof frame 2 to close it using the opening and closing shaft 22. Finally, release handle 35, and the locking post 34 will automatically return to the slot 12 due to the elastic force of spring 333. It is worth noting that anti-slip sleeves are provided on the contact surfaces between the locking post 34 and the slot 12, and the locking post 34 is relatively long to further ensure the locking stability of the locking post 34.

[0031] In this utility model, heat dissipation during the blowing process can be achieved through the heat dissipation holes 11 on the magnetic levitation blower 1. The mutual locking between the locking post 34 and the locking slot 12 makes it easy for users to clean the dust on the dustproof net 21, avoiding the impact of dust accumulation on the surface of the dustproof net 21 on the heat dissipation efficiency and ensuring the heat dissipation effect of the magnetic levitation blower 1.

[0032] 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.
