The present invention relates to an operation control system of the dust collecting apparatus, and in particular, it is possible to diagnose the vehicle body whether the operation abnormality of the dust collecting apparatus and take appropriate measures thereto, and the operation of the dust collecting apparatus which can transmit the disabled state to the user through the indicator. It relates to a control system.

In general, dust collectors in textile factories and manufacturing plants where dust is generated, when the filter's filtration function is lost after a long time of use, the user operates the dust collector and the solids of the filter in order to recover the filter. It stopped and dust removal or filter replacement was performed directly.

In addition, in order to know when an abnormality occurs in the dust collector, the user can only perform regular inspections, and thus, various problems occur when the dust collector is used.

Thus, the present invention has been made in view of the above-mentioned conventional problems, it is possible to detect the removal of a large amount of dust and contaminants in the dust collector filter, it can be removed, it can be recognized when a dust collector abnormal situation occurs The purpose is to provide an operation control system of the dust collector.

Hereinafter, with reference to the accompanying drawings will be described in detail the technical configuration and effect for achieving the object of the present invention.

The high pressure air spray nozzle operated by the diaphragm valve 41 to the upper end of the filter 11 inside the dust collector 10 for sucking contaminated air in the room and discharging the air filtered with impurities through the filter 11. A differential pressure gauge 20 for embedding the pressure sensing means 13 and 13 'on the inner walls of the spaces A and B partitioned around the filter 11, and indicating the air pressure in the dust collector 10; Combining the warning light (L) and the alarm generating means (B) which is operated according to the abnormality in the dust collector 10, the air compressor 40 operated by the operation control unit 42 and the time adjusting unit 30 While having a 40 ', the pressure sensing means 13, 13' and the gauge 20 are connected via a specific pipe T, while dust and water droplet blocking portions are provided at a predetermined position in the pipe T. And (21) and (21 '), wherein reference numeral D denotes a dust collector, I suction port, and O discharge port.

Referring to the operation and effects of the present invention configured as described above in detail as follows.

While the work efficiency decreases due to a lot of dust such as a general textile factory, the operation of the dust collector installed to prevent air pollution is possible by the operation of the user's operation button, as shown in FIG. 10) while operating, the air containing various dusts in the workplace is sucked from the inlet 1, filtered through the filter 11 has a structure in which the pure air is discharged to the discharge port (O).

The pressure of the air sucked in this state is detected by the pressure sensing means 13 and 13 'installed on the side walls of the space A and the space B.

That is, assuming that the pressure of the intake air corresponds to the numerical value 10, the pressure of the air applied to the space A portion generates a pressure corresponding to the numerical value 10, and the pressure of the air passes through the filter portion in the space B portion. The pressure is weakened to generate a pressure corresponding to the values 10-3 to 7 (the above-mentioned space A part pressure values 10 and the space B part pressure values 10-3 to 7 are arbitrary values for the applicant for detailed description).

At this time, the pressure sensing means (13) (13 ') detects the pressure of the space A portion and space B portion, and displays it through the gauge 20, and at the same time to compare the pressure of the space A portion and space B portion In this case, it is determined whether the proper pressure is in the range and the appropriate action is taken.

For example, the pressure of the air sensed through the pressure sensing means 13 of the space A part and the pressure of the air sensed through the pressure sensing means 13 ′ of the space B part are compared and calculated, and thus the air in the normal range. If a value higher than the pressure (assuming that the pressure of the air sucked into 10 is assumed to be a normal range in the space A part air pressure-the space B part air pressure = 3 to 7 is normal range), various dusts are fixed to the filter part 11. The diaphragm valve 41 is opened by the operation control unit 42, and the high pressure air generated by the compressor 40 is injected through the high pressure air injection nozzle 12 to the lower end thereof, so that the filter 11 is opened. Various dust adhered to the dust is dropped and the dust is collected in the dust collecting unit (D).

In addition, when the detected pressure in the space A part and the space B part is less than the normal range, the pressure detected in the space B part is lower than the normal range. Detected abnormal condition because air pressure = 2 ~ 2 of the detected pressure-space of the part is lower than the allowable range.) Due to the long use of the filter 11, the specific part is torn off or the position of the filter 11 is fixed incorrectly. It is determined that the incoming air flows directly from the space A portion to the space B portion without passing through the filter 11, and displays this through the gauge 20, and turns on the warning light L and the alarm for replacing the filter 11. The means B can be generated so that the user can be aware of it and take appropriate measures (filter replacement). Here, in the process of detecting the pressure of the space A portion and space B portion through the gauge 20, the space A portion and space B portion is directly connected to the gauge 20 by a pipe T such as a pipeline. When a small amount of dust is introduced into the gauge 20 or water droplets are formed on the inner wall of the pipe due to a temperature difference between the inside and the outside of the pipe generated by the flow of air, and water droplets collect and flow into the inside of the gauge 20, By preventing the gauge 20 from being inoperable, the dust and water droplet blocking portions 21 and 21 'are formed at a predetermined position between the pipe T and the gauge 20. Depending on the air injection time of the time control unit 30 set by the user's operation periodically operating the air compressor (40 ') while injecting high-pressure air, water droplets and piping accumulated in the water droplet blocking unit 21 (21') Drain the water droplets formed on the inner wall of (T) If the dust is collected in the dust collecting unit (D) by the reverse flow to the dust collector 10 can be removed.

The above process will be described according to the operation flow of FIG. 2.

Input the high pressure air injection time and the cycle time of the high pressure air injection in the pipe according to the dust removal of the filter required for the operation of the dust collector, and when the operation button is pressed (101), the device is operated (102) and the spaces A and B When the negative pressure is detected (103), the pressure of the space B portion against the space A portion is compared and calculated to determine whether the numerical value is within the allowable range (104). Otherwise, if the numerical value is higher than the allowable pressure range (105), Following the air injection, the filter unit removes dust (106), and if the value is lower than the pressure allowable range, it generates a warning dynamic light and an alarm sound (107) and notifies the central control room (111). If it is a numerical value, it is determined that the water droplet removal cycle time is applied to the pipe T (108), and when the removal time is reached, the air compressor 40 'is operated for a set time to remove water droplets in the pipe T (109) and the operation stop pressure ( 110) Continued until it becomes an apparatus for operating be fulfilled.

As described above, the present invention enables the self-judgement of the presence of an abnormality of the filter 11 and the cleaning of the filter 11 when the dust collector 10 is used, and the appropriate measures accordingly. It is possible to remove the water condensation phenomenon on the pipe (T) with) in advance, the abnormality of the filter 11 can be accurately confirmed through the gauge (20) and the life of the filter unit is extended It is an invention that can see the advantages.
