Anti-fiber aeration-cooling device for frequency converter of two-for-one twister

Abstract

The invention discloses an anti-fiber aeration-cooling device for a frequency converter of a two-for-one twister. The anti-fiber aeration-cooling device comprises a bottom plate, a front panel, two side plates, a top cooling cover plate, short fiber filter screens, filter screen cover plates and mesh-shaped air inlet ducts, wherein the front panel and the two side plates are arranged on the bottom plate in an enclosure manner; the two side plates are arranged in parallel; the top cooling cover plate covers the front panel and the two side plates; an opening shell formed by the top cooling cover plate, the two side plates, the front panel and the bottom plate sheathes the back face of a control cabinet frame of the two-for-one twister; cooling screen meshes are formed in the top cooling cover plate; the side face or the bottom part of the opening shell is provided with the mesh-shaped air inlet ducts; seen from the height direction, the mesh-shaped air inlet ducts are lower than the position of the frequency converter; each short fiber filter screen is arranged the inner side of the corresponding mesh-shaped air inlet duct; each short fiber filter screen is pressed by four peripheral edges of the corresponding filter screen cover plate; anti-fiber air inlets are formed in each filter screen cover plate; a gap exists between each filter screen cover plate and the corresponding short fiber filter screen. According to the anti-fiber aeration-cooling device for the frequency converter of the two-for-one twister, the frequency converter can be better protected from the influences of dust and fiber fluffs, and a good aeration-cooling effect is achieved in a limited space.

Description

【Technical field】 [0001] The invention relates to a textile machine, in particular to a protective cooling device for controlling electric appliances such as frequency converters of two-for-one twisters. 【Background technique】 [0002] In the existing textile factories, the ambient temperature in the general spinning workshop is high, the humidity is high, and the content of dust and fibers in the workshop is high. Among them, the two-for-one twister is a necessary production equipment, and its operation is characterized by long continuous operation time. The maintenance cycle is long, and during its long-term operation, more and more dust and fiber fluff will be adsorbed to the frequency converter and other control electrical components in the electrical control cabinet, making the practicality of the frequency converter and other control electrical components The effective heat dissipation area is gradually reduced, which leads to a sharp decline in the heat dissipation pe...

[0002] In the existing textile factories, the ambient temperature in the general spinning workshop is high, the humidity is high, and the content of dust and fibers in the workshop is high. Among them, the two-for-one twister is a necessary production equipment, and its operating characteristics are long continuous operation time. The maintenance cycle is long, and during its long-term operation, more and more dust and fiber fluff will be adsorbed to the frequency converter and other control electrical components in the electrical control cabinet, making the practicality of the frequency converter and other control electrical components The effective heat dissipation area is gradually reduced, which leads to a sharp decline in the heat dissipation performance of the inverter and other electrical components, which can easily cause the inverter to overheat and alarm, and in serious cases will directly lead to damage to the power device of the inverter and short circuit
