Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a dust collector, and more particularly, to an apparatus including a filter for trapping dust, a fan for sucking dust-containing air and exhausting purified air, and a dust receiver for accommodating dust removed from the filter. In addition, the present invention relates to a dust collector in which a fan serving as a vibration source is arranged at a lower portion of a main body to suppress generation of noise and vibration and to prevent dust collected by flowing air from rising.

[0002] A dust collector capable of trapping dust from dust-containing air and exhausting purified air has a casing generally in the shape of a rectangular parallelepiped or the like. This is because dust collectors are often installed at one corner of a building, for example, so as not to be obstructed in factories and the like. For this reason, since the air discharge section is provided on the top plate of the casing so as not to face the wall, etc., the fan that sucks in the dust-containing air and sends it to the filter and exhausts the purified air is generally located in the upper part of the casing. Placed in space.

[0003] In the casing of the dust collector, at least a filtering space in which a filter is arranged and a mechanical space in which a fan is installed are secured in terms of functions. The rooms that form each space are arranged side by side or stacked up and down. In such existing dust collectors, the filter is arranged two-dimensionally on the upper surface of a box installed in the filtration space, or the filter itself is cylindrical and is arranged, for example, with the upper end closed. It is generally done.

In any case, a tray for receiving dust blown off from the filter is arranged below the filter, but an air passage is secured so as to introduce dust-containing air from a space between the tray and the filter. I have. Therefore, after the air is introduced from directly above the tray, it rises in the box or the filter cylinder, and the air that has passed through the filter is once filled in the filtration space. The purified air is led into the machine space by a suction force of a fan through a duct or the like, and is discharged to the outside from an air discharge portion provided in the casing. Dust adhering to the filter is dropped on the tray by the wiping device during the suspension, and is appropriately removed and discarded.

[0005]

[Problems to be solved by the invention]

 As can be seen from the above, the sucked dust-containing air flows on the tray, and the collected dust soars by the sucked air. The sooted dust will reattach to the filter, causing the filter to become clogged early and requiring frequent sweeping operations, and other maintenance work. Have a problem with.

Incidentally, the fan is the heaviest in the dust collector. In addition, it has movable parts such as an electric motor and an impeller, so it becomes a vibration source. On the other hand, dust collectors have to secure a lot of space for air to flow due to their functions, and this has the problem of amplifying the vibration caused by the fan. In particular, when the filtering space and the mechanical space are arranged vertically and a fan is installed in the upper space, there is a problem that noise and vibration increase. Furthermore, if a heavy fan is present on the upper side, the casing must be made stronger, and sufficient measures against vibration must be taken.

[0007] The present invention has been made in view of the above problems, and its purpose is to minimize vibration when a filtration space and a mechanical space are overlapped in order to reduce the installation area of a dust collector. At the same time, it is possible to reduce the rigidity of the casing, thereby reducing costs.Also, it is possible to prevent the collected dust from flying up due to the circulating air and prematurely clogging the filter. An object of the present invention is to provide a dust collector capable of maintaining a high filtering effect.

[0008]

[Means for Solving the Problems]

 The present invention contains a filter that captures dust by passing dust-containing air, a fan that sucks in dust to send dust-containing air into the filter and exhausts purified air, and contains dust that has been blown off from the filter. Applies to dust collectors with dust receivers that can be removed for disposal. The feature is that, with reference to FIG. 1, the dust collector includes a main body 5 and a lid 6 which is put on an inclined surface 5a formed in an upper half 5A thereof. A dust chamber 8 (see FIG. 2) into which dust-containing air is introduced and an air passage 9 through which purified air flows are provided in the upper half portion 5A of the main body 5 substantially parallel to the inclined surface 5a. It is formed by being defined by the first partition 10 provided and the second partition 11 erected on the partition toward the inclined surface side. On the other hand, in the lower half 5B, a bucket 3 which is connected to a dust chamber 8 (see FIG. 2) in an airtight manner via a hopper 18 is detachably provided, and a duct provided below the air passage 9 is provided. The fan 4 connected to the suction port 4A through the fan 15 is disposed. A relay passage 20 that guides purified air that has flowed out of the dust chamber 8 to the air passage 9 is formed inside the lid 6. The filter 2 is mounted in a posture inclined toward the upper half at the boundary between the dust chamber 8 and the relay passage 20.

[0009]

[Effect of the invention]

 According to the present invention, the upper half of the dust collector main body mainly has a dust chamber and an air passage, and the lower half is provided with a heavy dust receiver and a fan, so that the overall structure is stable. In addition, the rigidity of the main body casing does not become excessive, and the cost can be reduced. And while the vibration and noise generated by the fan is a box with a lot of space, there is little possibility of amplifying it.

[0010] Since the filter is provided at the inclined boundary between the dust chamber located in the upper half and the relay passage of the lid, the dust blown off from the filter does not fall on the other filter without falling on the other half. It falls and is stored in a bucket. Therefore, the blown-out dust is hardly soared by the dust-containing air introduced into the dust chamber when the operation is resumed, and the occurrence of filter clogging can be delayed.

[0011] Replacement of the filter is only required by opening the cover and pulling it out, and maintenance work is extremely simple. Moreover, since the lid is located in the upper half, there is no needless burden on the operator. If the filter is attached to the dust chamber side, it can be easily removed and replaced simply by opening the lid. Needless to say, not only can the filter function when the filter is attached to the lid, but the workability is further improved by replacing the entire lid.

[0012]

[Embodiment of the invention]

 Hereinafter, the dust collector according to the present invention will be described in detail with reference to the drawings. FIG. 3 is a front view showing the entire dust collector. FIG. 1 is a sectional view taken along the line II in FIG. 3, and FIG. 2 is a sectional view taken along the line II-II in FIG.

As can be seen from FIG. 2, the dust collector 1 has a filter 2 that captures dust by passing dust-containing air, and a dust that has been removed from the filter is housed and taken out for disposal. A dust receiver 3 is provided. As shown in FIG. 1, a fan 4 is installed to suck in the dust-containing air and exhaust the purified air. The dust receiver and the heavy fan, which can be taken in and out freely, are arranged in the lower part which forms a box as a whole by securing a space and a passage described later.

More specifically, as shown in FIG. 4, the dust collector includes a main body 5 and a lid 6 that covers the upper half 5A thereof, and the upper half thereof has an inclined surface 5a formed on the front side. I have. That is, as shown in FIG. 5, the main body casing includes an upper half 5A having a triangular side view and a lower half 5B having a rectangular side view connected to the upper half. The arrow has a rectangular shape as shown in FIG.

On the other hand, the lid 6 is put on the inclined surface 5a of the upper half 5A as shown in FIG. 5, and in this example, a hinge 7 is provided at the upper end, and the lid 6 can be opened upward as shown in FIG. You can do it. Although the lid 6 is enough to be thin, it is generally box-shaped in order to secure a space through which air can flow. When such a thin lid is placed on the upper half 5A of the main casing at an angle, not only does the dust collector have a unique appearance, but also the arrangement of the filter described later becomes a form that does not exist in the past. It is also convenient for the payment of the payment.

Referring to FIG. 6, the upper half 5A of the main body includes a dust chamber 8 into which dust-containing air is introduced and an air passage 9 through which purified air flows. It is formed. This is because the dust chamber 8 and the air passage 9 are provided inside the first partition 10 substantially parallel to the inclined surface as shown in FIG. 2 and FIG. It is defined by a second partition 11 (see FIG. 6) which stands upright on the inclined surface side. That is, the first partition is substantially parallel to the inclined surface when viewed from the side, and the second partition partitions the front space of the first partition into right and left. Therefore, a dust chamber 8 and an air passage 9 are formed side by side on the inclined surface side of the upper half 5A by these partition walls, and a triangular back space 12 (FIGS. (See 2).

Since the filters are arranged in the dust chamber 8 as will be described later, the beam for mounting the upper and lower edges of the flange portion 2a provided in each filter 2 shown in FIG. 7 is hidden in FIG. It is arranged to extend to. The left and right edges of the flange portion are placed on the second partition wall 11 and the face plate 13 having a small width on the left side of the dust chamber shown in FIG.

In the lower half 5B of the main body casing, a dust collection space 14 shown in FIG. 2 connected to the dust chamber 8 and an air discharge space 16 connected through a duct 15 below the air passage 9 shown in FIG. These spaces are defined by a lower partition wall 17 having a vertical posture that bends when viewed in plan as shown in FIG.

In the dust collection space 14, a deep bucket 3 for receiving dust dropped from the dust chamber is disposed so as to be able to enter and exit the dust collection space from the front surface of the main casing. Therefore, the dust chamber 8 and the dust collection space 14 are in communication with each other via the hopper 18 in FIG. 2, and the upper opening of the bucket 3 can be brought into close contact with the vicinity of the lower end of the hopper. In addition, it is structured to be attached via an elevating mechanism 19 shown in FIG.

As shown in FIG. 2, a relay passage 20 for guiding purified air from the dust chamber 8 to the air passage 9 (see FIG. 4) is formed inside the lid 6. In this example, since the filter is attached to the dust chamber side as described below, this lid simply forms a box shape. Beam 21 is provided. Then, a known shaking device 22 for applying vibration to the back surface of the filter 2 to remove dust from the filter is provided.

The filter is arranged at the boundary between the dust chamber and the relay passage. However, since the filter is fitted on the front side of the dust chamber, it is mounted in an inclined position. As the filter, a known filter having a fold as shown in FIG. 6 (see also FIG. 7) is used. One filter may be used as long as it is large, but in this example, four filters 2A, 2B, 2C and 2D are arranged vertically.

The fan 4 that sucks the dust-containing air into the filter and exhausts the purified air is installed in the air discharge space 16 as shown in FIG. Note that the fan is actually stored with the impeller casing 4a in an oblique posture as shown in FIG. The suction port 4A is connected to the duct 15 of FIG. 1 through a tube, while the exhaust port 4B is opened in an air discharge space 16, and this air discharge space is defined by a triangle defined by a first partition 10. The exhaust air is temporarily retained in a large space behind the main body casing because it is connected to the rear space 12 in a shape like a circle.

The air intake passage 23 for taking in the dust-containing air is secured by a duct that crosses the air passage 9 and faces the second partition 11 that defines the dust chamber 8 as shown in FIG. The intake 24 is provided on a side wall of the main casing. On the other hand, air outlets 25 for exhausting the purified air to the outside are provided in the form of louvers on both walls of the main body casing defining an air discharge space (see FIG. 3). The external opening of the air intake passage may be provided on either the left or right side wall. However, when the external opening is provided on the opposite side from the position shown in FIG. Air can be immediately introduced into the dust chamber 8.

The lifting mechanism 19 of the bucket 3 shown in FIG. 9 has a structure as shown in FIG. This mechanism is lifted and lowered through a support bar 31 projecting to the left and right of the bucket 3. During operation, the mechanism is lifted slightly from the floor, and the upper end thereof supports the hopper 18 shown in FIG. In this case, dust that has fallen from the dust chamber 8 can be hermetically contained through a packing material (not shown).

Referring to FIG. 10, a link mechanism with handle 33 is provided on the inner side wall of dust collection space 14. It comprises an L-shaped lever 34, a U-shaped link 35 and a swing arm 36 integrated with the handle. The L-shaped lever 34 is a bent portion, and the swing arm 36 is pivotally supported at one end by horizontal pins 37 and 38, respectively, and one end of the U-shaped link 35 is connected to the L-shaped lever 34. The other end is rotatably connected to an intermediate portion of the swing arm 36 at the distal end.

Normally, the handle 33 is at the position shown by the solid line in FIG. 10, and when the handle 33 is raised to the position shown by the solid line in FIG. 11, the swing arm 36 is lowered. The swing arm is formed with a recess on which the support bar 31 is placed. When the recess is lowered, the bucket 3 is also lowered. When the swing arm 36 is fully lowered as shown in the figure, the caster 39 of the bucket lands, and the support bar 31 comes off the swing arm.

In this state, the bucket 3 can be pulled out to the front of the dust collector body, and the bucket in which the dust has been discarded can be put into the dust collection space 14. When the handle 33 is lowered, the swing arm 36 places the support bar 31 and raises the bucket 3. When the handle is lowered to the position of the imaginary line, the bucket 3 comes into close contact with the hopper or its vicinity. The position of the imaginary line in FIG. 10 is the same as that of FIG. 11, but when the handle 33 is further lowered to the position of the solid line, the tip of the L-shaped lever 34 exceeds the neutral point, and the weight of the bucket acts on the link mechanism. The position of the bucket is maintained. Incidentally, reference numeral 40 shown in FIG. 8 is a front cover that covers the front surface of the lower half part in a good shape, and has a gate-like shape as shown in FIG.

In such a dust collector, air is circulated and dust is captured as follows. When the fan operates, dust-containing air is sucked from the air intake passage 23 shown in FIG. 4 and immediately introduced into the dust chamber 8 shown in FIG. When air passes through the filter 2 and passes through the relay passage 20 of the lid 6, dust adheres to the filter and is removed. The purified air moves in the lid 6 and flows rightward in FIG. 6, and enters the air passage 9 formed in the upper half 5A.

The air descends through the air passage 9 shown in FIG. 1, reaches the duct 15, and is sucked into the fan via the tube. The air discharged from the fan outlet 4B fills the air exhaust space 16 and the rear space 12, and the air is exhausted from the louver 25 (see FIG. 5) which is an air outlet provided in the main body casing. Is done. By the way, the air that has flowed out of the exhaust port 4B is discharged toward a wide space including the back space 12, so that the flow is decelerated, so that the air can be discharged quietly without accompanying the exhaust vibration.

For example, at the end of the day's operation, the dust adhering to the filter 2 is removed by pushing and pulling the shaking device 22 shown in FIG. 2 with the knob 41 shown in FIG. The dust slides on the inclined first partition 10 and is stored in the bucket 3. At this time, dust falling from the filter in the inclined position hardly gets on the adjacent filter and does not hasten the clogging of the filter.

Since the dust is completely dropped into the bucket, even if dust-containing air circulates in the dust chamber 8 when the operation is resumed, the flow does not reach the bucket, and dust can be scattered. As much as possible. Since air flows along the maze by the main body 5 and the lid 6, dust can be uniformly and efficiently collected by all the filters.

When replacing the filter, by opening the lid 6 as shown in FIG. 4, the filter can be sequentially taken out from the upper half portion 5A, and the replacement operation is easy. The air intake can be provided on either side of the main casing and can be selected according to the situation at the installation site. Since air is taken in from the right in FIG. 3, a blind lid 42 is attached to the air intake in the left main casing. The loading and unloading of the bucket is also easily performed by the above-described lifting mechanism 19, and even a bucket in which a large amount of dust has accumulated can be easily carried out by the casters 39.

Although the dust collector is provided with a space in various places due to its function, since a heavy fan and bucket are provided at the lowest part, even if the main body becomes tall, its stability is low. Good. Therefore, it is also possible to prevent the rigidity of the main body casing from being excessively designed. Even if vibration is generated from the fan, it will not be amplified because it is near the ground, and noise will be reduced.

In the example described above, the filter is mounted on the dust chamber side. However, the filter may be mounted on the cover body, that is, on a portion corresponding to the dust chamber on the relay passage side. In any case, if the filter is located at the boundary between the dust chamber and the relay passage, the intended purpose can be achieved. In the latter case, if the lid is provided as a hinge connection that is detachable from the main body, the filter can be replaced by merely replacing the entire lid, and the workability can be further improved.
