Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a melting apparatus and a melting method using a melting tank.

[0002]

2. Description of the Related Art It is known that a photographic emulsion containing gelatin is prepared in a manufacturing process of a photographic light-sensitive material, then cooled and gelled, and then dissolved again when coated on a support. As a method for dissolving such a gel-like substance, the gel-like substance is put into a dissolution tank as a substance to be dissolved, and the central part of the dissolution tank is stirred by a stirrer, and the dissolution tank is covered with a heating jacket and heated and dissolved. It is well known that a batch-type dissolving method is repeated in which, when all the gel-like substances in the dissolving tank are dissolved, the dissolving substance is taken out as one set.

[0003] However, in this batch-type dissolving method,
Not only does it take a very long time until all the gel-like substances in the dissolution tank dissolve, but also the problem that the performance of the photosensitive emulsion fluctuates because the dissolved substance dissolved in the initial stage is continuously heated. Also, with a propeller stirrer that stirs only in the central part of the dissolution tank, the gel-like material cannot sufficiently flow in the dissolution tank, and there is a portion that stays for a long time on the inner wall surface (heating surface) of the dissolution tank. Fluctuations in the performance of the photosensitive emulsion in the portion that occurred and stayed on the inner wall surface were particularly problematic.

To solve such a problem, Japanese Patent Laid-Open No.
In JP-A-85069, a baffle plate (baffle plate) is provided on an inner wall of a melting tank to cause vertical convection in addition to horizontal convection by a stirrer, thereby forming an inner wall of a melting tank (heating surface). There is disclosed an invention that constantly renews a gel-like material that comes into contact with a gel to promote dissolution. In addition, a metal mesh outlet is provided at the bottom of the dissolving tank to continuously discharge the dissolving material, so that the dissolving material can be efficiently dissolved without staying in the dissolving tank for a long time. Is what is possible.

[0005] The melting apparatus disclosed in Japanese Patent Application Laid-Open No. 9-85069 is specifically configured as shown in FIG. FIG. 13A is a cross-sectional view, and FIG. 13B is a top view. In the figure, reference numerals 101 are a melting tank, 102 is a heating jacket, 103 is an outlet, 104 is a wire mesh, 10
5 is a discharge pipe, 110 is a stirrer, 121 is a vertical baffle plate, and 122 is a horizontal baffle plate. Stirrer 11
At 0, 111 is a rotating shaft, 112 is a first rotating blade of the two-stage rotating blade that is arranged near the upper edge of the horizontal baffle plate 122, and 13 is arranged near the lower edge of the horizontal baffle plate 122. This is the second rotating blade that has been removed. The first rotor has an S-shape.

In the description of Japanese Patent Application Laid-Open No. 9-85069,
The gel-like substance in the dissolving tank 101 not only causes a horizontal circular motion by the stirrer 110 but also the gel-like substance is finely crushed by the baffle plate and also causes a vertical flow. It says that the contact surface with the inner wall is constantly renewed, and dissolution can be promoted efficiently.

However, in the melting apparatus disclosed in Japanese Patent Application Laid-Open No. 9-85069, the rotating blades are arranged on the upper and lower edges of the horizontal baffle plate 122 so as to sandwich the horizontal baffle plate 122.
In the horizontal direction corresponding to the thickness, the gel-like material stays.
It was also found that the flow of the gel in the vertical direction did not occur as much as expected.

[0008]

Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited thereto.

FIG. 1 is a schematic diagram showing a continuous melting apparatus provided with a stirrer having two stages of rotating blades having different phases. FIG. 1A is a sectional view, and FIG. 1B is a top view.

In the drawing, reference numeral 1 denotes a dissolution tank for dissolving a substance to be dissolved such as a gel, and 2 denotes a dissolution tank.
Is a heating jacket for heating the dissolving tank 1 by covering the outside thereof, 3 is an outlet for discharging a dissolved material such as a sol-form coating liquid, and 5 is a discharge pipe for the dissolved material. 4 is a wire mesh for not discharging insoluble matter, and 10 is a stirrer. Hereinafter, in the description of the drawings, components denoted by the same reference numerals represent similar members and have similar functions.

The stirrer 10 has two stages of rotating blades 12 and 13 having different phases. In the present embodiment,
The rotating blades 12 and the rotating blades 13 are each two blades, and each blade of the two blades is connected to each other by forming an S shape at a position of 180 degrees with respect to the rotating shaft 11. The phrase “out of phase” means that the S-shape does not overlap in the upper stage (rotor blade 12) and the lower stage (rotor blade 13). That is, the connection position of the blade with the rotation shaft 11 is different depending on the step. In the present embodiment, the rotating blades 12 and the rotating blades 13 are arranged with a phase shift of 90 degrees.

In the present embodiment, the stirrer 10 is
Two S-shaped blades are provided in two stages.
It may be a flat plate shape that is not bent but not bent, or may have three or more blades, or may have three or more rotating blades.

In the continuous melting apparatus shown in FIG. 1, a melting tank 1 is appropriately heated by a heating jacket 2.
The stirrer 10 is rotated around a rotating shaft 11 by a drive source (not shown) to cut and stir the material to be melted, and to constantly renew the contact surface of the material to be melted that comes into contact with the inner wall surface of the melting tank 1 which is the heating surface. By causing the fluid to flow, the substance to be dissolved is dissolved. The rotation direction of the stirrer 10 can be either clockwise or counterclockwise in FIG. 1B as appropriate according to the characteristics of the material to be melted, but the material to be melted is pressed against the heated surface. The clockwise rotation is preferable when the effect is aimed at, and the counterclockwise rotation is desirable when the effect to scrape the substance to be melted from the heating surface is aimed. The melt is filtered by a wire net 4 arranged on the bottom of the melt tank 1 and discharged through a discharge pipe 5.

As in the present embodiment, the effect of the multi-stage rotating blades and the fact that each of the rotating blades has a different phase has the following effects. That is, it is possible to reduce the problem that the powder is crushed into small blocks and cannot be uniformly stirred. In addition, since the rotating blades have multiple stages, the contact surface of the material to be dissolved with the inner wall (heat transfer surface) of the melting tank 1 is excellently renewed, and the melting speed is increased.
These effects can be expected as the gap between the peripheral edge of the rotary blade 12 or 13 and the inner wall of the melting tank 1 is smaller.
