Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a dustproof electrical cabinet. Background Technology

[0002] Electrical cabinets are made of steel and are used to protect components and ensure their proper functioning. The materials used to manufacture electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are more flexible than hot-rolled steel plates and are more suitable for the manufacture of electrical cabinets.

[0003] The dustproof structure of the currently used dustproof electrical cabinets uses dustproof mesh to filter dust, which can effectively prevent larger dust particles from entering the electrical cabinet and strengthen the protection of the internal structure of the electrical cabinet.

When the air carrying fine dust particles passes through the membranes 15, Brownian motion occurs, causing the fine dust particles to be adsorbed by the fiber surface of the membranes 15, thereby preventing fine dust particles from entering the electrical cabinet.

[0038] Reference Figure 2 , Figure 3 and Figure 5 The pulse assembly includes a delivery pipe 6, which is fixedly connected to the inside of the electrical cabinet housing 1. The inner sides of all four ends of the delivery pipe 6 are fixedly connected to the outer sides of the fixing threaded blocks 7. An air tank housing 5 is fixedly connected to the outer side of one end of the delivery pipe 6. The air tank housing 5 is installed on the outer side of the electrical cabinet housing 1.

The push rod of the electric push rod 4 is slidably connected to the inner side of the air tank housing 5. A top plate 19 is fixedly connected to the bottom end of the electric push rod 4 for squeezing the air tank 20. By opening the two valve assemblies 21, gas is stored inside the air tank 20 through the fan assembly 22. Under the push of the top plate 19 driven by the electric push rod 4, the gas quickly enters the pulse tube 18 through the delivery pipe 6. The pressure of the gas flow impacts the fine dust on the surface of the diaphragm 15 through the holes of the pulse tube 18, causing the fine dust to fall into the collection box 11 and be collected.

[0039] Reference Figure 2 , Figure 3 and Figure 6Two filter screens 13 are slidably connected to the inside of the outer casing 9. A filter plate 12 is fixedly connected to the inner top of the outer casing 9 to prevent large impurities from entering the interior of the electrical cabinet housing 1 and to prevent dust from entering the interior of the electrical cabinet housing 1 when cleaning the outside of the diaphragm 15. Fixing blocks 26 are fixedly connected to the sides of the two filter screens 13. A handle 10 is fixedly connected to the outside of the fixing blocks 26.

A fan assembly 14 is provided inside one end of the outer shell 9 for bringing external gas into the electrical cabinet housing 1. A valve assembly 21 is fixedly connected to the middle of the delivery pipe 6. A valve assembly 21 is also fixedly connected to the air inlet of the fan assembly 22 for controlling the gas flow. A collection box 11 is fixedly connected inside the electrical cabinet housing 1 for collecting dust falling from the side of the diaphragm 15.

[0041] Working principle: External air is brought into the electrical cabinet by the fan assembly 14. Large dust particles are intercepted by two filters 13. When the air carrying fine dust particles passes through the diaphragm 15, Brownian motion occurs, causing the fine dust particles to be adsorbed by the fiber surface of the diaphragm 15, thus preventing fine dust particles from entering the electrical cabinet. The two valve assemblies 21 are opened to allow the air to pass through the fan assembly 22 and be stored inside the air tank 20. Under the push of the top plate 19 driven by the electric push rod 4, the air quickly passes through the delivery pipe 6 and enters the pulse tube 18. The pressure of the air flow impacts the fine dust particles on the surface of the diaphragm 15 through the holes of the pulse tube 18, causing the fine dust particles to fall into the collection box 11 and be collected. By pulling the connecting plate 24 outward, the hanging rope 28 drives the locking block 29 to retract inward under the elastic force of the spring 27, thereby causing the two filters 13 to be removed from the outer casing 9.
