Description

[Detailed explanation of the idea] The present invention relates to a feed storage tank.

More specifically, it is a reinforced plastic laminate that is sloped at a steep angle on the inner surface of an outdoor feed storage tank that is made up of a cylindrical body and a portion of an inverted cone-shaped hopper installed below it. The membrane was installed to cover the corner formed by the internal vertical surface of the body and the internal slope of a part of the hopper, as well as other uneven surfaces inside the tank, to prevent the stored feed from accumulating in those areas. This relates to feed storage tanks.

BACKGROUND ART A feed storage tank made of reinforced plastic and installed outdoors that is integrally formed with a cylindrical body part and a portion of an inverted conical hopper provided below the body part is conventionally known.

This feed storage tank is normally installed vertically and suspended on a frame. Feed is input and stored through a manhole provided at the top, and when necessary, the feed is removed by opening the outlet provided at the bottom of the hopper. This is repeated from time to time.For example, as shown in Fig. 1, structurally, the upper cylindrical body part 1 is provided with a band attachment part 2 necessary for suspending the feed tank body on the mount. Therefore, a convex portion 4 is formed on the inner surface, and a corner portion 5 is formed by the vertical surface of the cylindrical body portion and the inclined surface of the hopper portion 3.
Stored feed accumulates on these inner surfaces, and convection does not take place, so it gradually accumulates and becomes old, losing its freshness as feed, so there is the inconvenience of having to manually scrape off the accumulated feed from time to time. .

The present invention relates to an improvement of the conventionally known reinforced plastic feed storage tank as described above, and its gist is that it includes a cylindrical body whose axis is perpendicular to the horizontal plane and an inverted conical hopper provided at its lower end. A reinforced plastic feed storage tank consisting of a reinforced plastic laminate in the shape of an inverted truncated cone, the inner surface of which has an inclination angle intermediate between the internal vertical surface of the body and the internal inclined surface of the hopper part. The feed storage tank is made of reinforced plastic, and is constructed of a feed storage tank constructed of reinforced plastic, which is installed on an internal vertical surface of the body and an internal inclined surface of a part of the hopper.

The present invention will be explained below based on the drawings showing one embodiment.

In Fig. 2, 6 is a reinforced plastic layer made of unsaturated polyester with inorganic aggregates such as titanium oxide and calcium carbonate, which constitutes the skeleton of the main body of the feed storage tank. As a result, an inner surface corner portion 5 is formed at a location where the inner surface step 4 and the cylindrical body portion 1 and the hopper portion 3 below it change phase.

Reference numeral 7 denotes an outer reinforced plastic laminate, for example, glass fiber impregnated with an unsaturated polyester resin and stacked on top of each other, covering the entire outside of the reinforced plastic layer 6 forming the skeleton of the feed storage tank; 8 is a cylindrical reinforced plastic layer; The vertical inner surface of the body part 1 and the inclined inner surface of the hopper part 3 below it are constructed across the inner surface step 4 and the inner surface corner 5, and are directly spread over the entire inner circumference of the feed storage tank. For example, polyester resin, vinyl chloride resin, or other composite or resin film, or thick craft, which connects and forms a steeply sloped surface that is an intermediate slope between the internal vertical surface of the body and the internal slope of a part of the hopper. 9 is a paper-like sheet, and 9 is an inner reinforced plastic laminate that also integrates the surface of the sheet 8 and covers the entire inner surface of the feed storage tank, and is made of, for example, glass fiber and unsaturated polyester similar to the outer reinforced plastic laminate 7. They are impregnated with a resin, and are stacked on top of each other using the sheet 8 as a support plate and cured.

As mentioned above, the present invention is a feed storage tank made of reinforced plastic that consists of a cylindrical body and an inverted cone-shaped hopper provided below the body. The structure is constructed so as to cover the inner surface step formed by providing the band attachment part and the inner corner formed by the vertical surface of the body section and the partially inclined surface of the hopper, and the vertical inner surface of the body section and the partially inclined surface of the hopper. A reinforced plastic laminate with a large inclination angle that connects directly to the surface is installed all around the inner surface of the storage tank, so that the stored powdered feed does not accumulate in the internal steps or corners. The entire stored feed will be taken out and consumed.

In addition, a reinforced plastic laminate is installed at the inner corner of the inner surface to form a sealed cavity, so even if the outer surface of the tank becomes hot due to sunlight, the insulation effect of the cavity will prevent the tank from heating up. Seizure and deterioration of feed are prevented.

On the other hand, in winter, for feeds whose contents are likely to freeze or contain a large amount of water, the inner corners have a heat insulating effect, so they can be kept warm or, in some cases, by internal fermentation heat. Freezing is prevented and the bridging phenomenon is prevented.

Furthermore, the reinforced plastic laminate installed at the inner corner has the strength as a structural material, as if it were also used for the tank itself, and is firmly connected to the body and a part of the hopper, which improves its structure. is approximately triangular in cross-section, making the entire tank more rigid.

Furthermore, the outside of the inner corner forms the corner of the tank, and it is common to provide a smaller step at this part and support the tank with a belt.

A reinforced plastic laminate is installed here, and the inner corner portions are sealed.

Even if the corners are worn and holes are formed due to friction with the belt, the presence of the reinforced plastic laminate prevents internal feed from leaking, pests or water from entering, or the tank from being destroyed. There's nothing to do.

Therefore, it is useful as a reinforced plastic feed storage tank.
