JPS60181620A - Bucket dust amount detector for dust collector - Google Patents

Abstract

PURPOSE:To enable the indication of the disposal time of dust by providing a detector beneath the bottom plate of a bucket for accumulating dust. CONSTITUTION:For example, a microswitch 11 is used as detector 1. When the bottom plate 9a of a bucket 9 bent down due to the weight of dust DS to turn ON the microswitch 11, an ON signal S1 is sent to a display to operate and thus, the disposal timing of dust is indicated by lamp display or an alarm.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bucket dust amount detection device suitable for use in a fixed-quantity type small or medium-sized M collector.

Among dust collectors, in the case of large dust collectors with large air volume and capacity, there is a hopper at the bottom of the filter chamber, and when a detector such as a level switch installed in this hopper detects dust, it will be sent to the outlet of the hopper. The connected rotary valve is connected to a screen conveyor or other unloading machine to automatically discharge accumulated dust, but the air volume and capacity are small and the detector and unloading machine are In the case of a fixed-rate small or medium-sized dust collector that is not installed, the dust is collected in a bucket stored inside the machine that can be pulled out freely, and when the time is right, the bucket is pulled out and the dust is disposed of. Because the system relies on the intuition of the staff, various problems have occurred, such as sometimes too much dust accumulates, making it difficult to draw out the bucket, and dust flying up and re-contaminating the filter. .

The present invention has been developed in view of the above-mentioned points, and its purpose is to activate the dust indicator when the dust accumulated in the buckets 1 to 1 reaches a certain maximum level to indicate when it is time to dispose of the dust. An object of the present invention is to provide a bucket dust amount detection device for a dust collector devised to notify the user of the amount of dust and thereby prevent excessive accumulation of dust. The whole or part of the bucket is configured to be gradually distorted downward depending on the limbs of the accumulated dust, and a detector is installed on the bottom side of the bucket to detect the outside of the dust collector in response to the distortion of the bottom plate. It is configured to operate a dust amount indicator installed at the

Embodiments of the detection device according to the present invention described above will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a partially sectional front view showing an example of a quantitative dust collector implementing the detection device of the present invention, and the inside of the machine body, which is generally indicated by the reference numeral 1 in the figure, is separated by a partition plate 2. It is divided into two upper and lower chambers: a clean chamber 3 and a filter chamber 4. A fan 6 rotated by a motor 5 is installed in the clean chamber 3, and a bag filter 7 is installed in the filter chamber 4. Pulled-
There is C. 8 is the dust suction tough 1 connected to the above filter to 4.
The dust-containing air sucked into the filter chamber 4 through the duct (8) by the rotation of the fan 6 is filtered and purified by passing through the filter 7.
Air is exhausted from the clean room 3 to the outside of the aircraft body 1.

In addition, 9 in the figure is a dust packet stored in the lower box of the filter chamber 4 so that it can be freely drawn out. Among the dust sucked into the filter chamber 4 through the dust suction duct 8 with the air, relatively coarse dust is removed. Due to its own weight, it falls directly into the packet 9 and is piled up.Other light dust is collected by the filter 7, and the dust I~, which has been collected and coarsened by the filter 7, is collected by the dust removal device ( The dust is removed from the filter 7 by a filter (not shown) and falls into the bucket 9, where it is piled up.

In the dust collector configured as described above, the bottom plate 9a of the packet 9 is gradually bent downward due to the weight of the dust DS accumulated inside, and is relatively naturally restored when the accumulated dust DS is discharged. In the present invention, when the bottom plate 9a of the packet 9 is distorted to a predetermined value due to the weight of the dust DS, the lower side of the bottom plate 9a is In response to this, the detector 10 installed in the
is amplified by the amplifier AP and transferred to the outside of aircraft 1.
It is configured to operate a digit 1-11 indicator 10A. In addition, as the dust amount indicator 10Δ, when the above-mentioned detection signal S if 4 is an ON/OFF signal, an alarm or the like is used as the indicator lamp, and when it is a level signal, various indicators are used. Meters are used.

Next, embodiments of the above-described detector 10 will be explained in order according to the descriptions in the drawings.

First Embodiment In the first embodiment shown in FIG. 2, a microswitch 11 is used as the detector 10, and the bottom plate 9a of the packet 9 is distorted downward by the weight of das h D S and the microswitch 11, the ON signal S1 is displayed on the display 1.
0A to activate the display 10A, and the lamp display will issue an alarm to let you know when it is time to dispose of the dust. - For example, 27 packets for customers in packet 9 used in the above embodiment
If you set it to 1, the density in this customer bucket 9 will be 0.2 to 2.09/CG's! - When about 80% of the DS is accommodated, the total weight becomes approximately 40 mm, making it difficult to draw out the "C packet-〇" and dispose of the dust DS.
1 In this example, the appropriate value is set at about 18 klJ, and when about 18 kg of dust 1) S accumulates in the bucket 9,
The packet 9 is configured so that the bottom plate 9a, which is distorted by its weight, just turns on the microswitch 11.

Second Embodiment In the second embodiment shown in FIG.
Place a magnet 12 on the a side, and place a sensing element 1 such as a magnetic sensor or a proximity switch on the inner bottom surface of the body 1 corresponding to the magnet 12.
When the magnet 12 gradually approaches the sensing element 13 due to the distortion of the bottom plate 9a and reaches a predetermined distance,
The detection element 13 sends a signal S2 to the dust amount indicator 10A to activate the display, thereby informing the user of the time to discard the dust.

In addition to the above-mentioned two embodiments, there is also a sensor 10 in which a strain gauge 1 () is attached to the bottom plate 9a of the packet 9, and an actuating lever in contact with the bottom surface of the bottom plate 9a, which is linked to the distortion of the bottom plate 9a. Various structures are conceivable, such as a type in which the operation period is captured by a sensor or a variable resistor, but the selection of these is arbitrary.

In addition, FIG. 4 shows that a thin circular reaction part 9al is installed in the center of the bottom plate 9a of the packet 9, so that the detector 1 can be suspended with less dust.
These are examples of buckets 1 to 1 devised to obtain sufficient strain m to properly operate J-0.

As explained above, the dust collector bucket holder according to the present invention is equipped with a detector on the lower side of the bottom plate of the bucket 1 that collects dust. Since this detector detects the amount of dust and activates the dust amount display, there is no need to pull out the bucket and check the amount of dust, and the display has the advantage of letting you know when it is time to dispose of the dust. This eliminates problems such as a large amount of dust accumulating and making it difficult to pull out and carry the bucket, and the re-contamination of the filler due to falling dust. 4M construction can be easily done by installing a detector under the bottom plate of the bucket, so it has the advantage of being very simple in construction and can be easily implemented on conventional dust collectors.
In particular, it is suitable for use in small and medium-sized stationary dust collectors that cannot be equipped with a rotary valve and a discharger such as the Compe A7.
