Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filling device for filling a slurry-like paste containing chemical powder into a porous hoop, such as a spongy three-dimensional mesh metal hoop.

Recently, three-dimensional mesh metals that closely resemble sintered substrates have been developed.
Since this three-dimensional mesh metal has extremely high porosity, it can be filled with a large amount of chemical substances at high density, and can be used for catalysts for chemical plants, electrodes for batteries, etc. The present invention aims to provide a filling device for continuously filling a porous hoop such as a three-dimensional mesh metal hoop with a slurry paste containing chemical powder. An explanation will be given based on drawings showing examples.

FIG. 1 is an enlarged view of the three-dimensional mesh metal A, and as is clear from this enlarged view, its porosity is extremely large.

In addition, this three-dimensional mesh metal is processed into a hoop shape as shown in FIG. 2 in order to be continuously conveyed through the apparatus. FIG. 3 shows a filling device showing one embodiment of the present invention.

Reference numeral 1 denotes a porous hoop, and the porous hoop 1 is filled with a paste containing a chemical substance while being continuously fed through the apparatus by a feed roll 2.

3 is a paste tank in which paste 4 is stored, and this paste tank 3 is provided with a stirrer 5 for stirring the paste 4.

6 receives the back side of hoop 1 in paste tank 3, and
T is a filling scraper main body to which a plurality of filling scrapers 8 are attached, and this filling scraper main body 7 is moved to the hoop by a motor 13 via a pin 9, a connecting rod 10, a pin 11, and a crank disk 12. It is driven to reciprocate in parallel with the longitudinal direction of 1.

Further, the tip of the filling scraper 8 performs a sliding movement in substantially contact with the surface of the hoop 1, so that the paste 4 on the surface of the hoop 1 is rubbed into the hoop 1. Further, the paste 4 in the paste tank 3 is guided from the nozzle 14 by a pressure pump 15 through pipes 16 and 17 to a pipe 18 attached to the filling scraper main body 7.
It is supplied onto the hoop 1 from a plurality of discharge nozzles 19 attached to the hoop 1 .

In this case, the pipe 17 is fixed 9, and in order to perform reciprocating motion, the pipe 18 attached to the filling scraper main body T is provided with a flexible part 20 that can be expanded and contracted between it and the pipe 17 to absorb relative movement. That's what I do. In addition, the hoop receiver 6
The paste 4 is constructed of a perforated plate 9 having a shape that allows the paste 4 to permeate through it very easily, and the paste 4 left over when the hoop 1 is filled flows back into the paste tank 3 through the hoop receiver 6. 21 and 22 are seal plates located in the longitudinal direction of the hoop 1 and provided near the entrance and exit of the paste tank 3. The tips of the seal plates 21 and 22 are fixed so as to be in contact with the surface of the hoop 1, Prevents water from flowing out of the tank.

23 is a fitting for attaching the pipe 18 to the filling scraper main body 7.

In FIG. 4, reference numeral 24 denotes a roller that guides the filling scraper body 7 along the side wall of the paste tank 3. This roller 24 is attached to a metal fitting 25 and ensures the movement of the filling scraper body 7.

Reference numerals 26 and 27 denote small walls located on both sides of the hoop 1 in the lateral direction and provided on the hoop receiver 6, so that a shallow reservoir of paste 4 is formed on the hoop 1 together with the seal plates 21 and 22. It has been devised.

In the filling device shown in the above embodiment, when the porous hoop 1 is simply filled with paste from one discharge nozzle while being conveyed in one direction, the filling density is relatively small. Per unit volume of porous hoop, 0.6 to 1.09/Cc (average value 0.89/Cc)
However, the dispersion was as large as 0.49/Cc.

However, when the porous hoop 1 is filled with paste from a plurality of discharge nozzles 9 as in the embodiment of the present invention, the filling density is 1.1 per unit volume of the porous hoop 1.
It was 0 to 1.309/Cc (average value 1.209/Cc), and the variation was also reduced to 0.29/Cc.
In other words, the packing density was greater than that of the single discharge nozzle method9, and its variation was greatly reduced. In this embodiment, the paste is continuously supplied from the plurality of discharge nozzles 19, but it is also possible to supply the paste intermittently. By providing a plurality of discharge nozzles 19 in this way,
The paste can be supplied to the entire porous hoop 1,
Further, by the functions of the small walls 26, 27 and the seal plates 21, 22 provided on the hoop receiver 6, a shallow paste reservoir 9 is formed on the porous hoop 1, so that a plurality of discharge nozzles 19 and The supplied paste is passed through the filling scraper 8.
As a result, the inside of the porous hoop 1 is sufficiently filled. Further, even when the porous hoop 1 is stationary, the paste is supplied to the entire porous hoop 1, so that sufficient paste can be filled. Also, when the porous hoop 1 is moving in one direction, the filling amount increases sequentially in the transport direction of the porous hoop 1.
The effect is great when filling the paste while conveying the paste. In the above embodiment, one discharge nozzle 19 is provided between each filling scraper 8, but the number can be reduced as appropriate, such as by skipping one discharge nozzle.

Further, although the discharge nozzle 19 is fixed to the filling scraper main body 7 so as to move together with the filling scraper 8, it is also possible to fix the discharge nozzle 9 to the paste tank 3 so that it does not move. As described above, the filling device of the present invention includes a paste supply device that pumps the paste in a paste tank onto a hoop, and a paste supply device that is provided above the filling scraper and has a plurality of discharge nozzles. Because it is equipped with piping, as long as there is enough paste in the paste tank, the pump can supply paste onto the refoop at a constant speed, even if the paste level in the paste tank fluctuates slightly. , can be filled under constant conditions at all times.

In addition, there is a small size provided on the hoop receiver located on both sides of the hoop in the width direction, and a small size provided on the hoop holder located on both sides of the hoop in the longitudinal direction.
- A shallow pool of paste is formed on the hoop by the seal plate installed near the entrance and exit of the storage tank, so the paste is evenly distributed on the hoop, and the entire hoop is covered. It has excellent features such as no variation in packing density.
