Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a simple powder removal device for efficiently adsorbing and removing gaseous powder.

(Prior art) Recently, this type of device has a structure that increases the contact area between the gas and the adsorbent surface by placing a folded net or thin pipe-like object in the gas passage, as shown in Figure 1. was used. In the figure, 1 is a container, 2 is a gas inlet, 3 is a gas outlet, and 4 is an adsorbent such as a folded net-like material or a thin pipe-like material for increasing the adsorption surface. That is, the conventional device has the above-mentioned configuration, and in order to increase the probability of adsorption of powder, oil or the like is applied to the surface of the adsorbent 4 in the container 1, but the adsorbent 4 is fixed. Therefore, even if the adsorption efficiency is high on a new surface where powder has not yet been adsorbed, as more powder is adsorbed, the adsorption efficiency of that surface may decrease, or the surface may become clogged due to increased adsorption. In addition to this, the adsorbent 4 has to be replaced from time to time, which is disadvantageous.

(Purpose of the invention) In order to eliminate these drawbacks, the purpose of the invention is to fix a plurality of circular suction plates at regular intervals to a rotating shaft that is supported on the center line of a cylindrical container. A plurality of slits are provided in the radial direction at fixed angles on the plate, and the positions of the slits are sequentially displaced by a fixed angle so that they do not overlap each other in the axial direction.This suction plate rotates at a low speed. When this happens, new adsorbent is constantly deposited on the adsorption surface by passing through the adsorbent stored at the bottom of the container, and gas is introduced from the top of the container to create a spiral path formed by the slits in the adsorption plate. To provide a powder removal device with high adsorption efficiency, in which powder in a gas is efficiently adsorbed and collected in a storage part during a process in which powder is passed through a container and sent out to the outside from a delivery port at the top of a container. . The present invention will be described in detail below with reference to embodiments.

(Structure of the invention) FIG. 2A is a schematic explanatory diagram showing the structure of an embodiment of the invention, in which 5 is a cylindrical container;
L and 5R are the left and right side walls, 6 is a gas inlet, 7 is a gas outlet, 8 is a circular suction plate, 9 is a slit provided in the radial direction, and 10 is a plurality of circular suction plates 8. The fixed rotating shaft 11 is a powder adsorbent liquid such as pump oil. FIG. 2B is a perspective view showing the arrangement of the circular suction plate 8, its slits 9, and the rotating shaft 10, and FIG. 2C is a diagram showing the arrangement of the slits 9 of the circular suction plate 8. The book slits are arranged 90 degrees apart. That is, in this embodiment, the gas inlet 6 and the gas outlet 7 are arranged in the side walls 5L, 5R of the cylindrical container 5 at upper positions away from the horizontal central axis, respectively.
A circular suction plate 8 having slits 9 provided in the radial direction is arranged so that the slit positions are sequentially shifted by 90 degrees as shown in FIGS. 2B and 2C, and the rotation axis 1 is
0 at regular intervals. Therefore, the powder adsorption liquid 11 is placed at the bottom of the cylindrical container 5 on the rotating shaft 10.
When the rotating shaft 10 is rotated at a low speed of about 1 to 10 times per second by an external drive source, the surfaces of the plurality of circular suction plates will be filled with the adsorbed liquid 11.
The gas containing the powder is introduced into the container 5 from the inlet 6 at the upper left corner, comes into contact with this, passes through the slits sequentially, enters the next space, repeatedly contacts each adsorption plate, and is adsorbed. The powder is washed away by sinking into the adsorption liquid 11 stored together with the adsorption plate, and the purified gas is sent out from the right delivery port 7. Incidentally, only the newly adsorbed liquid adheres to the circular suction plate 8 and moves upward, and the gas comes into contact with it and is purified and sent out, and the same process is repeated thereafter.

FIG. 3 is a layout diagram showing the number of slits and their positional relationship in a circular suction plate according to another embodiment of the present invention.
In the figure, the solid line shows the slit position of the first circular suction plate, the dotted line shows the slit position of the second circular suction plate, the chain line shows the slit position of the third circular suction plate, and the fourth and subsequent Repeat the same arrangement as above. In addition, Fig. 3A shows the case where each circular suction plate with two slits is arranged at an angle of 60°, and Fig. 3B shows the case where each circular suction plate with three slits is arranged at an angle of 120°. If the angles are shifted by 60°, Fig. 3 C shows the four slits.
This shows the case where circular suction plates are arranged at 90° intervals and are shifted by 45°. It goes without saying that this embodiment also has an effect equal to or greater than that of the first embodiment.

(Effects of the invention) As explained above, in the present invention, multiple radial slits are arranged on the gas powder adsorption plate at appropriate angles, so the gas flows in a spiral shape inside this container and each adsorption As the adsorbent liquid comes into contact with the surface of the plate and constantly wets the surface of each adsorption plate as it rotates at low speed, it has the advantage of high adsorption efficiency for powder in gas, and has an unprecedented effect as a device for removing powder in gas. It is something to play.
