Description

Filter automatic changer of dust collector

The present invention is installed in all kinds of equipment using a bag filter including a filter automatic exchanger, more specifically, a dust collector of the dust collector automatically checks the contamination state and performs the filter replacement automatically to improve the performance of the device. The present invention relates to an automatic filter exchange device for a dust collector that can improve and reduce environmental pollution.

In general, the oiler (Oiler) is a facility for injecting rust preventive oil on the surface of the strip, by removing the residual rust preventive oil, that is, fume, which is an environmental pollutant by inhaling the fume generated when the rust preventive oil is injected by the action of the dust collector installed thereon Only pure air was discharged.

Figure 1 shows the Euler fume dust collector, in order to check the replacement time of the filter (1) during operation of the device, it is necessary to loosen the various bolts (2) (2 ') can not be replaced when necessary, environmental pollution more than the allowable Since the rust preventive oil (waste oil), which is a substance, is discharged into the air, even if the fume suction fan 3 is normally operated, the suction capacity due to filter contamination is reduced.

Because of this, there is a risk of safety accidents such as fire caused by loss of oil in the oiler facility, and line breakage occurs even when replacing or checking the filter, resulting in lowered productivity and reduced quality.

On the other hand, as shown in FIG. 2, the DC motor 4 that delivers power to a facility requiring precise speed and tension has a severe heat generation due to its facility characteristics, and if the cooling failure occurs in the DC motor, it operates normally. This was not the case and the impact on the line work was greatly increased.

Since more than 20 DC motors are installed in the line, which is a reprocessing process, breakdown and line breakage occurred when the filter 5 is contaminated. The filter 5 is cut as much as necessary as shown in FIG. Due to the need, more than 10 minutes of work time was required, so it was exchanged only at clean water.

In addition, all the facilities in which the filter, including the rolling mill fume pan, are used have the above problems, such as defects caused by deterioration of the efficiency of the facility and emission of pollutants above the allowable value. There were problems such as deterioration and deterioration of quality.

The present invention has been made in view of the problems occurring in the conventional dust collector as described above, the object is to provide an automatic filter replacement device for a dust collector that can automatically check and replace the dirty state of the filter.

The present invention for achieving this object, while the filter installed in the dust collecting pipe is wound into the case to proceed in the form of a film of the camera to recover as much as used and withdraw a new filter, the filtering action to replace the filter By detecting the pressure deviation of the fluid passing through the pipe and comparing the detected values, the filter is automatically replaced by driving the driving motor, thereby preventing the line from stopping due to the replacement of the filter. It improves productivity, prevents breakdown by improving product quality and efficiency of facility, and improves filtering function, which is the ability to remove pollutants, and emits pollutants below the allowable level.
