JP6026774B2 - Dust collector cleaner and work status management method using the same - Google Patents

Description

The present invention relates to a dust collector cleaner and a dust collector cleaner , which mainly includes a dust collector such as a diesel engine called DPF (Diesel Particulate Filter), and a dust collector such as an air filter for an automobile engine . It relates to the work status management method .

As the dust collector such as the DPF or the air filter is used, the collected dust (dust) or the like adheres to the filter element and reduces the purification ability. For this reason, these dust collectors are managed to maintain engine performance by cleaning and removing dust at appropriate intervals until the dust collector itself deteriorates and a replacement cycle comes. .
For removing dust adhering to such filter collection elements, a physical dust removal method such as air blow is used. In addition, in order to prevent deterioration of the surrounding work environment due to dust scattering due to air blow, these dusts are removed. In addition, a suction method for collecting the powder without scattering is considered (Patent Documents 1 and 2).

As an example of this, an air filter is used as a processing target, and the air filter is inserted into a sealable chamber to perform air blowing and suction. However, its spread is not sufficient. The reason is that the apparatus introduction cost is excessive in view of the actual work at the service site, that is, the work frequency, the work difficulty, and the like.
In addition, in such a conventional large-scale apparatus, although the cleaning operation can be performed fully automatically, the work time cannot be sufficiently shortened by including the setup of the operation.
In addition, this device is a dedicated device only for the air filter, and does not take into account the cleaning of the DPF, which has recently been required to work, and cannot be used in combination.

  Therefore, the applicant can process both the air filter and the DPF, can process even an irregular shape, has good workability, and can be supplied at low cost. From the viewpoint of having a simple configuration, an apparatus suitable for the actual work situation in an actual maintenance service site has been developed and has already been filed for a patent (Patent Document 3). Since then, the applicant has continued to develop this type of device, and will develop a device that can further reduce the cost while realizing further adaptation to the actual work situation at the actual maintenance service site. It came to.

Furthermore, the dust collector can be aligned and erected only by placing the dust collector on the storage portion, and a stable working posture can be obtained.
Furthermore, even if it is a dust collector of any diameter, such a stable working posture can be obtained.
Furthermore, it is possible to prevent dust from being released from the storage portion to the outside by the top plate protruding to the upper opening side of the storage portion.
Furthermore, especially when the dust collector is covered with a plastic bag, the removed dust is diffused to the outside by dropping the bottom of the plastic bag below the top plate that protrudes to the upper opening side of the storage part. Can be surely prevented.
Furthermore, since the entrainment air flows from the gap below the dust collector, the entrainment air can carry the dust to the discharge port and smoothly discharge it to the outside.

Symbol C is a dust collector cleaner according to the present invention, which cleans and removes the dust D collected by the dust collector f.
As the dust collector f, a DPF unit fd for collecting diesel gas dust (mainly ash components and carbon particles), an air filter fa and a catalyst fc for cleaning automobile combustion air are typical. Although mentioned as a thing, it cannot be overemphasized that the dust collector currently used for other industrial equipment etc. is applicable.

First, it is preferable that the dust collector cleaner C is configured to be relatively compact and movable in consideration of use in an automobile maintenance service factory or the like. In other words, the rectangular work base 1 in a plan view is provided with a storage portion 15 for the dust collector f and a dust suction device 2 and an air gun device 3.
First, the work base 1 is formed by bending a steel plate into a box shape as an example, and a form in which a side plate 11 is formed on each side of the top plate 10 and a bottom surface is opened is taken (an example) As W460 × B460 × H300 mm). Further, in order to make the dust collector cleaner C movable, a caster 12 is provided at the lower part of the side plate 11, a handle post 13 that is appropriately bent is provided on one surface of the side plate 11, and a handle 14 is provided at the upper end thereof. .
Note that the dust collector cleaner C can be used as a dust collector f or a carriage of the dust suction device 2 as shown in FIG. 9, and considering the usage pattern, the diameter of the caster 12 is about 100φ. Is preferred. Further, in this case, it is preferable to consider the safety by fixing the dust collector f and the dust suction device 2 to the handle post 13 using the rubber belt B or the like.

Further, the work base 1 is provided with a storage portion 15 for the dust collector f, and this storage portion 15 is a funnel-shaped member below a part of the top plate 10 cut into a circular shape. However, it is installed in a state where a part of the top plate 10 is recessed. Further, the upper opening 15a of the storage portion 15 has a circular shape (in plan view) having a larger diameter than the end portion of the top plate 10 cut into a circular shape, and the end portion of the top plate 10 is the upper opening 15a. It is assumed to be a dust return 10a that protrudes inward. In addition, an intake pipe 15c is connected to the discharge port 15b formed in the lower part of the storage portion 15, and the hose 20 of the dust suction device 2 is connected to the intake pipe 15c.
Note that the storage portion 15 is a funnel-shaped member having an inclination angle of about 45 ° as an example, and the dust collector f is placed in the storage portion 15 with the exhaust side facing upward. In this state, the dust collector f can be aligned and erected, which will be described in detail later.
Further, the dust return 10a prevents dust D in the storage portion 15 from rising from the upper opening 15a, which will be described in detail later.
In this embodiment, the diameter of the storage portion 15 is set so that the dust collector f having the maximum diameter within the standard can be accommodated so as to correspond to the general standard of the dust collector f.

  Next, the dust suction device 2 will be described. As an example, a commercially available industrial vacuum cleaner is applied, and the suction hose 20 is connected to the intake pipe 15c. In this embodiment, as shown in FIG. 1, a vacuum cleaner used for other purposes in a maintenance shop is adopted as the dust suction device 2, but a dedicated small dust suction device 2 is prepared and used as a working base. The table 1 may be provided.

Next, the air gun device 3 will be described. This device has a vibrating nozzle 31 as a main member, and a trigger for controlling the ejection amount is provided on the proximal side of the vibrating nozzle 31. In addition, an air hose 33 is connected to the base end portion of the vibration nozzle 31, and this air hose 33 is connected to a pressure pipe of an air compressor 30 that is permanently installed in a maintenance service factory or the like via a regulator. The air hose 33 and the vibrating nozzle 31 are detachable by a coupler 33a provided in each.
Here, the vibration nozzle 31 will be described in detail. As shown in FIG. 6 (b), the nozzle 31 has a horn-shaped collar 31a and a jet pipe 31b. Air is jetted from the jet pipe 31b. When the jet pipe 31b is violated in the collar 31a by the reaction force of the air, an operating wind accompanied by a pulsating wave is generated, and it is hit with the air about 50 to 60 times per second against the spray target. It is possible to give a special effect.
In this embodiment, as an example, the vibrating nozzle 31 is used with an operating air pressure of 1.0 MPa and an air consumption of 250 l / min.
In addition, instead of the vibration nozzle 31, an expansion / contraction nozzle 32 as shown in FIG. 8 may be used, which is provided with an expansion / contraction jet pipe 32a.
The vibration nozzle 31 and the expansion / contraction nozzle 32 are mounted on an appropriate holder provided on the handle post 13 when not in use.
Note that a small compressor 30 may be prepared and provided in the work base 1.

The handle post 13 is also equipped with a suction brush 4 and a fine pressure measuring device 5. The suction brush 4 has a tubular body 42 in communication with a central portion of brush hair 41 that is implanted in a circumferential shape as an example, and the tubular body 42 is connected to the hose 20 in the dust suction device 2. It is provided.
The fine pressure measuring device 5 is a device for supplying air to be measured to the object to be measured through the air hose 33 from the compressor 30 and measuring the ventilation resistance. A rubber cup 51 is provided at the outlet. And a display 52 for displaying the measurement result. In this example, the one capable of measuring in units of 1 kPa was adopted.

The dust collector cleaner C of the present invention has a specific configuration as described above, and is used as follows to clean the dust collector f and manage the work situation .
[1. Cleaning the DPF unit]
First, cleaning of the DPF unit fd as the dust collector f will be described. As an example, the DPF unit fd has a plurality of long holes in the cylindrical outer tube f1 along the exhaust flow direction. An adsorbing element f2 such as a ceramic block is formed, and flanges f3 and f4 provided in both openings of the outer cylinder f1 are appropriately connected to the exhaust path of the engine E of the vehicle. Moreover, although the planar shape of the flange f3 and the flange f4 is an octagon as shown in FIG. 4B, other polygonal or circular shapes are also treated by the dust collector cleaner C of the present invention. Is.

(I) Setting (See Figs. 1, 3, and 4)
First, the DPF unit fd is set to the dust collector cleaner C. The operator operates the handle 14 to move the dust collector cleaner C to the vicinity of the vehicle, and the DPF unit is removed from the vehicle. The fd is placed in the storage unit 15 with the exhaust side facing upward.
At this time, the dust collector 1 comes into contact with the mortar-shaped inner peripheral surface of the storage portion 15, and as shown in the plan view of FIG. 4B, the gap G is formed between the flange f4 and the inner peripheral surface. Is formed. Further, such a gap G becomes substantially the same shape by aligning and erecting the DPF unit fd by the weight of the DPF unit fd, and can take a stable working posture. Moreover, since the accommodating part 15 has a mortar-shaped inner peripheral surface, as shown with a virtual line in FIG.4 (b), it is the dust collector f of any diameter within a specification. Such a stable working posture can be obtained.
At this time, since the height of the top plate 10 of the work base 1 is about 30 cm from the ground, the operator can set the DPF unit fd without requiring much labor.
Furthermore, since the top plate 10 is in a state in which three surfaces other than the surface to which the handle post 13 is attached are open, even when two or more workers cooperate to set the DPF unit fd. , Not subject to unnecessary regulations.

(Ii) Measurement of pass resistance before work (see Fig. 4)
Next, the pre-operation pass resistance is measured. The operator connects the air hose 33 to the fine pressure measuring device 5, starts the compressor 30, and sets the set pressure of the regulator 34 to 1.0 MPa as an example. .
Next, the rubber cup 51 is pressed against a predetermined measurement point on the upper end surface of the adsorption element f2, the trigger is pulled, air is blown, and the numerical value displayed on the display 52 is recorded. Then, as an example, measurement was performed at five locations.
Further, when measuring such a passage resistance, the dust suction device 2 is detached from the intake pipe 15c so as to prevent inadvertent air load fluctuations.
When such work is performed, the upper surface of the DPF unit fd is about 70 cm from the ground, so that a standard general male can take a natural work posture.

(Iii) Surface cleaning (see Fig. 5)
Next, the end surface (upper surface) of the adsorption element f2 in the DPF unit fd and the inner peripheral surface of the outer cylinder f1 positioned above the end surface are cleaned. The suction brush 4 is attached to the hose 20 of the dust suction device 2, and the dust absorption While the apparatus 2 is activated, the operator operates the suction brush 4 to suck and remove the dust D adhering to the surface.

(Iv) Cleaning the adsorption element (see Fig. 6)
Next, the hose 20 of the dust suction device 2 is attached to the intake pipe 15 c and the vibration nozzle 31 is attached to the air hose 33.
Then, in a state where the dust suction device 2 is activated, the trigger of the vibration nozzle 31 is pulled to blow air, and the long hole of the adsorption element f2 in the DPF unit fd is cleaned.
Specifically, spraying is performed in a state where the tip of the vibration nozzle 31 is separated from the adsorption element f2 by about 10 to 50 mm, and the working air accompanied by the pulsating wave ejected from the vibration nozzle 31 is generated by the adsorption element f2. It effectively acts on the dust D adhering in the long hole and peels it off, and the dust D is accommodated in the dust suction device 2 via the discharge port 15b. In the cleaning mode of the suction element f2 as described above, the tip of the vibration nozzle 31 does not come into contact with the suction element f2, so that damage to the suction element f2 can be avoided.

Further, during such work, since the working air blown from the vibrating nozzle 31 is blown over a range of 30 to 40φ, for example, the operator sets the vibrating nozzle 31 at a pitch of 20 mm in the vertical direction and the horizontal direction, for example. By making it move, spraying can be performed over the entire region without causing any residual blowing. Next, if necessary, the vibrating nozzle 31 is moved in a spiral to perform spraying.
Further, since the entrainment air flows into the lower portion of the DPF unit fd from the gap G, the entrainment air can carry the dust D to the discharge port 15d and can be smoothly discharged therefrom.
Incidentally, such a gap G can be formed even when the shape of the flange f4 is circular. Specifically, for example, as shown in FIG. 6C, a cross-shaped attachment 16 having one side longer than the diameter of the flange f4 is installed in the storage portion 15 in advance, and the DPF unit fd is mounted on the attachment 16. By mounting, the gap G can be formed between the circular flange f4 and the inner peripheral surface of the storage portion 15. In reality, due to manufacturing errors and deformations, the circular flange f4 does not come into close contact with the inner peripheral surface of the storage portion 15 without a gap, and a fine gap is generated. From this gap, the DPF unit fd Although it is weak, the entrainment wind flows in downward, but by intentionally forming the gap G as described above, the entrainment wind is generated and the dust D is smoothly transported to the discharge port 15d. Is possible.

Furthermore, since the upper part 15a of the storage part 15 is provided with the dust return 10a which protruded in the shape of a flange, the dust D can be prevented from diffusing from the storage part 15 to the outside.
The DPF unit fd has a configuration in which both openings of the outer cylinder f1 are provided with flanges f3 and f4. Therefore, when the vibrating nozzle 31 is acted on the upper opening, the lower opening The dust D flows out from the side, and the dust D does not flow out from the side periphery like the air filter fa. However, in order to avoid the operator from sucking the dust D, or when it is strictly required to prevent the dust D from being scattered around, an operation mode using the plastic bag P can be adopted. Specifically, the DPF unit fd was spilled on the outside of the flange f3 by performing a cleaning operation with a transparent plastic bag P formed with a hole into which an operator's arm can be inserted. The dust D is reliably prevented from being scattered around, and the dust D is guided by the plastic bag P and collected by the dust suction device 2 through the gap G and the discharge port 15b. At this time, by dropping the bottom of the plastic bag P below the dust return 10a, the dust D that has risen out of the upper flange f3 is surely guided into the storage portion 15 that is a dust absorption region by the dust absorber 2. It becomes.

In order to determine whether or not the removal of the dust D is smoothly performed, the DPF unit fd placed in the storage unit 15 is maintained in the placed state as shown in FIG. By tilting it, the vicinity of the bottom surface is visually observed. At this time, since the shape of the storage portion 15 is a funnel shape, even if such a posture of the DPF unit fd is taken, a stable self-standing state is maintained.
When air is blown by the vibrating nozzle 31 with the DPF unit fd placed on the storage unit 15 tilted, it can be visually confirmed that the dust D does not flow out.

(V) Measurement of pass resistance after work (see Fig. 4)
Next, the post-operation pass resistance is measured. The operator connects the air hose 33 to the micro pressure measuring device 5 and removes the hose 20 from the intake pipe 15c, and the location where the pre-work pass resistance is measured. The passage resistance at the same location is measured, and the numerical value displayed on the display 52 is recorded.
The degree of dust removal is determined based on the difference in passage resistance before and after the work, and the quality of the dust removal work is determined by comparing with data accumulated in advance. In addition, the completion of the dust removal operation can be objectively indicated using numerical values, and as a result, the reliability of the dust removal operation can be improved.

[2. Cleaning the irregular dust collector] (See Fig. 8)
Next, the cleaning of the catalyst fc as shown in FIG. 8 will be described. This catalyst fc is connected to the exhaust path of the engine E of the vehicle, and is connected to the front and rear of the DPF unit fd. It is. For this purpose, a connecting pipe f5 is provided between the outer cylinder f1 and the flange f3, and the distance from the flange f3 to the catalyst element f6 is increased. For this reason, it is difficult for the oscillating nozzle 31 to effectively act on the catalytic element f6, and here, an expansion / contraction nozzle 32 as shown in FIG. 8 is used.
Further, when the work using the above-described plastic bag P is performed, the workability can be improved by using the expandable nozzle 32.

[Other Embodiments]
In the above description, the DPF unit fd and the catalyst fc of the vehicle dust collector f have been described as the object of the present invention. However, the air filter fa shown in FIG. Needless to say, the dust D can be removed by applying to the dust collector f. In the case of processing the air filter fa or the air conditioner filter, the use of the plastic bag P is indispensable for preventing the dust D from being scattered around. Most of the air filters fa are cylindrical, but by using the attachment 16 shown in FIG. 6C as described above, the air filter fa and the inner peripheral surface of the storage portion 15 are separated. A gap G can be formed between them. And since the entrainment wind which flows into the lower part of the DPF unit fd from this gap G is generated, the dust removed to the outside of the filter fa by applying the operation wind ejected from the air gun device 3 from the inside of the filter fa. D can be reliably collected in the dust suction device 2.
Furthermore, considering that the dust collector cleaner C of the present invention is installed in a gas station or the like, the dust collector f may include a floor mat, an ashtray, and the like.
