Abstract
The utility model provides a control box for a frequency converter, which relates to a control device belonging to the field of textile technology. Restricted by the working environment, the converter control box of a fine spinning frame is enclosed type; the converter positioned in the control box has poor heat dissipation effect, which influences the normal production. The control box for a frequency converter provided by the utility model is provided with an aspiration channel and an air inlet; a dust-separation blower originally arranged on the fine spinning frame is utilized, the aspiration channel is connected to the box body of the dust-separation blower; the other end of the converter control box is provided with an air inlet, which ensures natural wind outside can timely replenish the converter control box, therefore, the temperature within the converter control box declines swiftly, and the electrical apparatus elements within the control box are not damaged owing to overheat and short circuit. Therefore, the normal production is ensured.
Description
The invention belongs to a kind of control device of textile technology field, especially for the spinning Frequency Converter Control case of silk spinning.
At the spinning production site of silk spinning, owing to be subjected to the restriction of the working environment of many dust and flyings, therefore what be used for that the Frequency Converter Control case of spinning frame adopts is enclosed, frequency converter is positioned at control cabinet, control cabinet is by the small fan heat extraction in the case, can't leave fast to a large amount of heat that frequency converter is produced in running.Add the production particular surroundings of spinning frame, to the louvre that makes a large amount of silk spinning dust and flyings be adsorbed on frequency converter, the heat of frequency converter inside can't in time be distributed, the frequency converter temperature inside reaches more than 80 ℃ sometimes.For these reasons, frequency converter has influenced the normal operation of producing often because of the overheated phenomenon that autostop takes place; moreover; the existence of the problems referred to above is returned production safety and has been brought unfavorable factor, the overheated fault that easily is short-circuited of electric elements, and then initiation fire.The instability that production brings to silk spinning, unsafe factor.
The technical assignment of the technical problem to be solved in the present invention and proposition is exactly to overcome the unsafe factor that prior art exists, a kind of frequency converter controller is provided, solves the heat dissipation problem of frequency converter, guarantee the frequency converter safe and stable operation, for this reason, the present invention is by the following technical solutions:
The Frequency Converter Control case has casing, is positioned at the frequency converter of casing, and it is characterized in that has aspiration channel and air inlet on the described casing, and described aspiration channel communicates with air box.Dust absorption fan is arranged in the air box.
Described aspiration channel is the pvc pipe of 50mm, and it is communicated with Frequency Converter Control case and two casings of air box.
As further perfect, be connected to the PVC blast pipe of 50mm on the air inlet.
The invention has the beneficial effects as follows: utilize the own dust absorption fan of original spinning frame, from in the casing of dust absorption fan in the control cabinet of frequency converter the pvc pipe with a 50mm be communicated with, the dust and the flyings that are adsorbed in the Frequency Converter Control case can be taken away by the dust suction airduct timely, the louvre that guarantees frequency converter is unobstructed, and heat can be come out the very fast inside from frequency converter.In addition, open an air inlet from the other end of Frequency Converter Control case again, also the pvc pipe with 50mm connects a blast pipe, and the natural wind of outside can be added in the control cabinet of frequency converter timely.Such one inhales a combination of advancing; make the interior temperature of Frequency Converter Control case with quick decline; make the running environment of frequency converter that the variation of matter take place; frequency converter is in the environment of a ventilation and heat all the time; the frequency converter temperature inside drops to below 50 ℃ by original the highest 80 ℃; frequency converter no longer takes place because of the overheated phenomenon that takes place freely to shut down, and the appliance component of control cabinet inside can not guarantee the normal operation of producing again because of the overheated phenomenon that is short-circuited and damages.
Fig. 1 is the structural representation of the control device of a kind of Frequency Converter Control case of the present invention.
Among the figure: 1-variable frequency control box body, 2-frequency converter, 3-aspiration channel, 4-air inlet, 5-air box, 6-dust absorption fan.
With an embodiment the present invention is done specific description below in conjunction with Figure of description.
As shown in Figure 1, this Frequency Converter Control case mainly comprises variable frequency control box body 1, frequency converter 2, aspiration channel 3 and air inlet 4, wherein: frequency converter 2 is positioned at variable frequency control casing 1, aspiration channel 3 and air inlet 4 are arranged on the variable frequency control casing 1, aspiration channel 3 adopts the pvc pipe of a 50mm, utilize the own dust absorption fan 6 of original spinning frame, aspiration channel 3 is with the casing 5 and the Frequency Converter Control case 1 two tanks internal communication of dust absorption fan.The other end of Frequency Converter Control case is opened an air inlet 4, and also the pvc pipe with 50mm connects a blast pipe, and the natural wind of outside can be added in the control cabinet of frequency converter timely.Linked to each other by dust absorbing air passage between many silk spinning spinning frames air box separately of work-yard, each parts mentioned above are known technology, no longer describe herein.
