Description

[Detailed Description of the Invention] The present invention relates to a dust collector whose filter can be easily cleaned, and is particularly suitable as a dust collector for welding fumes.

With conventional dust collectors, in order to clean the filter, it is necessary to disassemble the dust collector to some extent to take out or expose the filter. Paper filters were generally cleaned by sweeping the surface with a brush or the like. Since the dust from welding fumes is fine, welding must be done frequently to prevent clogging of the filter, for example, once a day.

However, in the conventional dust collector described above, it is necessary to disassemble the dust collector, and furthermore, a dust receptacle, a brush, etc. must be prepared separately, and the workability is extremely poor.

The purpose of the present invention is to provide a dust collector that solves the above-mentioned conventional problems. are combined so as to be slidable and engageable with each other, and a filter fixedly interposed between the intake passage and the exhaust passage is fixed to the exhaust pipe in a position parallel to the sliding direction, A cleaning brush that contacts a side surface of the intake passage of the filter is protruded from the intake pipe at a mounting position where the cleaning brush moves between both ends of the filter when the intake pipe and the exhaust pipe slide. This dust collector consists of a dust collector, in which a cleaning brush moves in contact with the filter by sliding an intake pipe and an exhaust pipe to clean the filter.

The present invention will be described below based on embodiments shown in the drawings.

The figure shows an embodiment of the present invention, in which the intake pipe 1
is formed into a vertical cylindrical container shape whose lower part is sealed with a bottom plate 11, and has an intake port 1 in a side wall 12 connected to a duct (not shown) extending to a welding fume generation source.
3, and a dust outlet 15 which is for discharging the dust accumulated on the bottom plate 12 and which is normally sealed with a lid 14, is open on the top surface, and has a ring-shaped receiving part on the outer periphery. A surface 16 is formed.
The exhaust pipe 2 combined with the intake pipe 1 has a side wall 21
is formed into a vertical cylinder shape that fits on the outside of the intake cylinder 1,
The interior is partitioned into upper and lower sections by shelf boards 22. The central part of the shelf board 22 is formed with a blower support part 23 recessed downward, and the blower 3 is attached thereto so that the top and bottom of the shelf board 22 communicate only through the inside of the blower 3, and the casing of the blower 3 A gasket 31 is interposed between the blower support portion 23 and the blower support portion 23 to form a seal, and an intake hole 32 is opened downward. A substantially U-shaped filter mounting auxiliary member 41 is fixedly extended downwardly on the lower surface of the blower support portion 23, and a mounting bolt 42 is provided protruding from the lower end. A filter holding plate 43 is fixed from below with wing nuts 44 via mounting bolts 42 . As a result, the cylindrical filter 4 is clamped between the filter holding plate 43 and the shelf board 22. The filter 4 is a strong paper filter in which a bellows is wound into a cylindrical shape and the top and bottom are fixed with fixing members 45. However, filters with other shapes and structures may be used as long as they are sturdy and have a fairly hard surface. Exhaust pipe 2
The upper part of the lid 25 is covered with a slit-shaped exhaust port 24, and a handle 26 is provided on top of the lid 25.

The intake pipe 1 and the exhaust pipe 2 are arranged such that the part of the exhaust pipe 2 that holds the filter 4 extends inside the intake pipe 1, and the side wall 21
are fitted so that they are on the outside, and the lower surface of the shelf plate 22 of the exhaust pipe 2 is placed on the receiving surface 16 of the intake pipe 1 via the packing 17. The internal space of the partitioned intake pipe 1 that reaches the filter 4 forms an intake passage 18, and the space that runs from the inside of the filter 4 of the exhaust pipe 2, through the inside of the blower 3, and from above the shelf board 22 to the exhaust port 24 forms an intake passage 18. It forms an exhaust passage 27. A side wall 12 of the intake cylinder 1 facing the filter 4
A cleaning brush 5 whose tip contacts the surface of the filter 4 protrudes from the upper end. As shown in FIG. 2, a large number of cleaning brushes 5 are arranged radially so as to fit inside the grooves of the bellows of the filter 4.

The engagement and fixing structure between the intake pipe 1 and the exhaust pipe 2 is the first
As shown in the figure and enlarged in FIGS. 3 and 4, the side wall 1 of the intake cylinder 1
An engagement guide member 6 having a groove-shaped cross section is fixed in the vertical direction with its bottom touching the side wall 12, and an engagement member 7 is fixed inside the lower end of the side wall 21 of the exhaust pipe 2 by spot welding or the like. ing. The inner widths of the flanges 61 and 62 on both sides of the engagement guide member 6 are approximately the same as the width of the engagement member 7, and
2 has a large notch 63 that is approximately the same as the vertical width of the engagement member 7 at the upper end, and the lower end engages the intake pipe 1 and the exhaust pipe 2 when the receiving surface 16 and the shelf plate 22 come into contact with each other. The engagement end 64 is cut at a height to engage the upper end 71 of the mating member 7. The engagement member 7 is provided at a position where its upper end 71 can engage with the engagement end 64 of the engagement guide member 6, and has an attacking surface 72 formed at the front end of the upper end 71 and a rotation stop projection 73 at the rear end. is formed. Further, the upper end of the bottom plate of the engagement guide member 6 is cut and raised to form a stopper 65 for preventing slippage.

In the dust collector having the above configuration, when the intake pipe 1 and the exhaust pipe 2 are engaged and fixed, the filter 4 is interposed between the intake passage 18 and the exhaust passage 27, so that the blower 3 is operated. Air containing dust is sucked in from the intake port 13, but when the air passes through the filter 4, it is filtered, becomes clean in the exhaust passage 27, and is discharged from the exhaust port 24. Next, when the exhaust pipe 2 is rotated in the direction of arrow A from the fixed state shown in FIG. 3, the engagement member 7 and the engagement guide member 6 are disengaged. When the exhaust pipe 7 is lifted upward, the engagement member 7 rises while being guided by the engagement guide member 6, and comes into contact with the stopper 65 at the upper end and stops. At this time, since the cleaning brush 5 also rises while sweeping the surface of the filter 4, the dust adhering to the surface of the filter 4 is removed and falls onto the bottom plate 11 below. By holding the handle 26 and moving the exhaust pipe 2 up and down, the cleaning brush 5 reciprocates over the surface of the filter 4 to perform cleaning. After that, when the exhaust pipe 2 is lowered and rotated in the direction opposite to the arrow A, the attacking surface 72 of the engaging member 7 first engages with the engaging end 64 of the engaging guide member 6, and then If you rotate it, the upper end 71 will be the engaging end 6.
4, the intake pipe 1 and the exhaust pipe 2 are engaged and fixed. When removing the exhaust pipe 2, rotate the exhaust pipe 2 in the direction opposite to arrow A when it is at the upper end in the cleaning state, the engaging member 7 will pass through the notch 63, and then remove the exhaust pipe 2. If you raise it up, you can remove it. When fitting and engaging the exhaust pipe 2, this operation can be performed in reverse. Also, if the filter 4 is cleaned several times and dust accumulates on the bottom plate,
The lid 14 is opened and the dust is discharged from the dust discharge port 15. For example, daily cleaning of filter 4 is done using brush 5.
Maintenance of the dust collector is extremely easy if the dust collector is discharged about once a week, and the dust collector is disassembled and the filter 4 is cleaned about once a month.

According to the dust collector of the present invention, since the filter can be cleaned without disassembling the dust collector, cleaning can be done frequently and easily.Moreover, since it can be done inside the dust collector, it does not stain the body or place. Cleaning is also quick. In addition, since the contact of the cleaning brush is kept constant, the filter is not strained and is not damaged, so the life of the filter can be maintained for a long time. Furthermore, since maintenance becomes easier, the dust collector is always kept in good condition, and the life of the dust collector is extended.
