Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a filter dust removal device for filtering dust in exhaust gas.

[0002]

[Prior art]

 As a filter / dust remover, there is, for example, a device for filtering and separating dust in exhaust gas through a filter medium as shown in FIG. In the figure, reference numeral 101 is a substantially cylindrical bag-shaped bag filter that uses woven cloth or the like as a filter medium, and the bag filters 101 are hung side by side in a housing 102. An exhaust gas duct 103 and a processing gas duct 104 are attached to the housing 102, and exhaust gas containing dust is introduced into the housing 102 from the exhaust gas duct 103. Further, the exhaust gas is sent to the bag filter 101, and the dust is filtered by the bag filter 101. The dust that has adhered to the bag filter 101 is removed by the removal mechanism 105.

[0003]

[Problems to be solved by the device]

 However, in such a filter / dust remover, a woven cloth such as cotton or synthetic fiber is used as a bag filter, and therefore cannot be used when the exhaust gas is at a high temperature, and cannot be filtered. It was difficult to easily separate the collected dust. There are also filters that use ceramics that can withstand high temperatures, but when heating each filter or sending compressed air from the opposite direction to remove the clogging of the filter, the material is brittle, so if you repeat this, it will break and endure. There was a problem that it was inferior.

An object of the present invention is to provide a filter / dust removal apparatus that can be used even when exhaust gas has a high temperature and is equipped with a bag filter having excellent durability.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, in the present invention, a cylinder which is erected in a substantially vertical direction, a piston which is slidably disposed in the cylinder, and a piston which is mounted on the piston are provided. A layer of iron pieces for filtering dust in the exhaust gas, an exhaust gas duct attached to the cylinder for introducing exhaust gas into the iron piece layer, and a piece of material for throwing up the iron pieces by vibrating the piston. The vibrating means and the electromagnet for adsorbing the iron piece thrown up by the vibrating means are provided. Alternatively, an opening is formed in the piston and a mesh material having a mesh smaller than the iron piece and larger than the dust is provided in the opening, and a bucket for collecting the filtered dust is provided at the bottom of the cylinder. It is configured to be attached.

[0006]

[Action]

 When the exhaust gas containing dust is introduced into the cylinder from the exhaust gas duct, the introduced exhaust gas is introduced into the bed of iron pieces. The exhaust gas passes through the passage formed between the iron pieces, but since the passage has a portion narrower than the dust, the dust is filtered by the iron piece layer. Here, since the exhaust gas is filtered by the iron piece layer, the iron piece layer exhibits a filtering action even when the exhaust gas is at a high temperature. When separating the collected dust, the iron piece is thrown up by the vibration of the piston by the driving means. At this time, when the electromagnet is energized, the iron pieces thrown up by the electromagnet are adsorbed and the filtered dust is easily separated. When the power supply to the electromagnet is stopped, the iron piece falls on the piston, and the iron piece layer is formed again.

[0007]

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. 1 to 3 are views showing a first embodiment of a filtration and dust removal apparatus according to the present invention.

In FIG. 1, reference numeral 1 is a cylinder made of non-magnetic metal (for example, stainless steel), which is erected in a substantially vertical direction. A piston 2 is arranged in the cylinder 1 so as to be slidable in the vertical direction, and an oval or distorted iron piece on the piston 2 or a small iron piece (diameter of a roughly flat sugar) as shown in FIG. Several millimeters) are placed in large numbers to form a layer. Since the iron pieces 3 are formed of layers of small iron pieces as described above, passages are formed between the iron pieces 3 so that gas and the like can pass therethrough, but dust 4 and the like can pass through this passage. Instead, it will be filtered by this layer of iron pieces 3.

One end of a connecting rod 5a is detachably attached to the bottom of the piston 2, and the other end of the connecting rod 5a is attached to the peripheral edge of a disk 5b rotated by an electric motor 5. The connecting rod 5a, the disk 5b and the electric motor 5 constitute a vibrating step 6 as a whole, and are for throwing up the iron piece 3 on the piston 2 in the cylinder 1.

The piston 2 slides up and down by the vibrating means 6, and the exhaust gas duct 7 is attached to the peripheral wall of the cylinder 1 within the range in which the piston 2 slides up and down. . A wire mesh 8 having a mesh smaller than the diameter of the iron piece 3 is stretched between the exhaust gas duct 7 and the cylinder 1 so that the iron piece 3 on the piston 2 does not go out from the exhaust gas duct 7. .

A processing gas duct 9 having a wire mesh 8 is attached to the peripheral wall on the upper side of the cylinder 1, and exhaust gas is introduced into the cylinder 1 from the exhaust gas duct 7 and dust 4 is removed. The processing gas is discharged from the processing gas duct 9.

An electromagnet 10 is provided on the top surface 1 a of the cylinder 1, and when the electromagnet 10 is energized, the iron piece 3 thrown up by the vibrating means 6 is attracted by the electromagnet 10. . Further, when the energization is stopped, the iron piece 3 is no longer attracted to the electromagnet 10 and falls onto the piston 2.

In order to filter the dust 4 in the exhaust gas, the piston 2 is positioned by the electric motor 5 immediately below the exhaust gas duct 7. At this time, the layer of the iron piece 3 is located at the open end of the exhaust gas duct 7. Therefore, when the exhaust gas containing the dust 4 is introduced into the cylinder 1 from the exhaust gas duct 7, the introduced exhaust gas is introduced into the layer of the iron piece 3.

The exhaust gas passes through the passage formed between the iron pieces 3, but since the passage has a portion narrower than the dust 4, the layer of the iron piece 3 filters the dust. Here, since the layer of the iron piece 3 filters the exhaust gas, the layer of the iron piece 3 exhibits a filtering action even when the exhaust gas has a high temperature. The processing gas from which dust has been removed is discharged from the processing gas duct 9 to the outside.

Next, when the electric motor 5 is rotated at high speed as shown in FIG. 3A, the piston 2 vibrates violently in the vertical direction, and the vibration of the piston 2 causes the iron piece 3 to be thrown up. At this time, when the electromagnet 10 is energized as shown in FIG. 3B, the iron piece 3 thrown up by the electromagnet 10 is adsorbed and the collected dust 4 is easily separated. When the electric motor 5 is stopped, the dust 4 falls on the piston 2.

Next, as shown in FIG. 3C, the connection between the connecting rod 5 a and the piston 2 is removed, and the piston 2 is removed from the bottom of the cylinder 1 while moving the electric motor 5 from under the cylinder 2. Sweep the dust 4 on the above. Next, the piston 2 is fitted into the bottom of the cylinder 1 and the electric motor 5 is returned to the bottom of the cylinder 1.

Next, as shown in FIG. 3 (d), when the energization of the electromagnet 10 is stopped, the iron piece 3 falls on the piston 2 and a layer of the iron piece 3 is formed again. The layer of the iron piece 3 thus formed can be used semipermanently (has durability) as compared with ceramics or the like.

Next, a second embodiment of the filter / dust removal apparatus according to the present invention is shown in FIGS. The same members as those in the above-mentioned embodiment are designated by the same reference numerals and the description thereof will be omitted.

An opening 2 a is formed on the upper surface of the piston 2, and a wire mesh 11 having a mesh smaller than the iron piece 3 and larger than the dust 4 is stretched over the opening. A connecting rod 5a is attached to the piston 2, and a crankshaft 13 is connected to the connecting rod 5a. The crankshaft 13 is rotatably supported by the cylinder 1 via a bearing 12 and is rotated by the electric motor 5.

When the electric motor 5 is driven, the piston 2 slides in the vertical direction via the crankshaft 13 and the connecting rod 5a, but the exhaust gas duct is below the range in which the piston 2 slides in the vertical direction. 7 is located, and the exhaust gas duct 7 has no wire mesh. The lower side of the cylinder 1 has a funnel-shaped hopper portion 1b, and a bucket 14 is detachably attached to the lower end of the hopper portion 1b.

Exhaust gas containing dust 4 is introduced into the cylinder 1 from the exhaust gas duct 7, and this exhaust gas flows into the layer of the iron piece 3 through the wire net 11. The dust 4 in the exhaust gas is filtered by the layer of the iron piece 3.

When the electric motor 5 is rotated at high speed as shown in FIG. 5A after filtering the dust 4, the piston 2 is violently vibrated in the vertical direction, and the iron piece 3 is thrown up. At this time, when the electromagnet 10 is energized, the iron piece 13 is adsorbed by the electromagnet 10 and the dust 4 is separated. The dust 4 passes through the mesh of the wire net 11 and falls into the bucket 14.

Next, as shown in FIG. 5B, when the dust 4 is collected in the bucket 14, the electric motor 5 is stopped. Next, as shown in FIG. 5C, the bucket 14 is removed, the dust 4 inside is removed, and the power supply to the electromagnet 10 is stopped. In this embodiment, the collected dust 4 can be thrown out without the heavy electric motor 5 having to be moved.

[0024]

[Effect of device]

 As described above, according to the present invention, since the exhaust gas is filtered by the iron piece layer, the iron piece layer exhibits a filtering action even when the exhaust gas is at a high temperature. Further, the iron piece on the piston is thrown up by the vibrating means, and the iron piece is adsorbed by the energized electromagnet to separate the dust, and when the energization is stopped, the iron piece layer can be formed again. This layer of iron pieces can be used semipermanently (durable) compared to ceramics and the like.
