Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drying device using solar heat used for processing hay, etc., and more particularly, the space behind the solar heat collector is used to dry harvested plants, especially aquatic plants. Dish drainer 9 relates to a drying device configured as a three-dimensional head of a storage basin.

(Background Art) In recent years, a method for improving the water quality of lakes and marshes that have become eutrophic by using a nutrient removal system using aquatic plants has reached the stage of practical application (for example, Japanese Patent Laid-Open No. 57-48392
(method described in the publication).

The important thing in this method is to recover aquatic plants that have grown and multiplied in lakes and marshes, absorbed enough nutrients, and solidified them (with their roots) on land, and at least prevent the situation from withering in the water and leaching out the salt nutrients again. That's true.

Therefore, it is important to treat the aquatic plants collected on land, and at present, solid fuel processing, composting processing, methane fermentation processing, etc. are common. In any of these treatments, a drying process of cutting off the aquatic vegetation is essential, and a drying device using solar heat as shown in FIG. 1 has been developed and used.

In this system, a solar heat collector 2 whose front surface is surrounded by a glass wall 1 is installed on a support 3 at an angle of inclination of 300 mm to the front edge, and an air inlet 4 is provided at the lower end of the solar collector 2.

At the upper end, a drying chamber 7 is provided which is surrounded by a glass wall 6 in the front through an air circulation floor 5 having a mesh structure or the like, and an exhaust pipe 8 corresponding to a so-called chimney is installed in the drying chamber 7. It is said that the configuration is as follows.

Fresh outside air is taken in from the air inlet 4 and heated by the solar heat collector 2, and the heated air is circulated upward into the drying chamber 7, thereby rapidly drying the aquatic plants 9 housed in the drying chamber 7. It is an energy-saving drying device because it dries quickly.

By the way, in this drying device, the height H of the solar heat collector 2 is about am, and the horizontal depth L is about 10 m.

It is a large structure with a height of approximately 20 meters perpendicular to the page.

Therefore, the back space 15 of the solar heat collector 2 is also extremely large. However, due to the lack of sunlight, it has been left as a dead space for sacred horses, making it uneconomical.

On the other hand, unless the aquatic plants recovered from the water are thoroughly drained and placed in the drying chamber 7, the drying efficiency will be extremely low. Not only that, but it is also inconvenient and uncomfortable to handle. ), a facility with a fairly large space was required to drain and process aquatic M*.

(Object of the Invention) Therefore, the object of the present invention is to utilize the space 15 on the back side of the solar heat collector 2, which has conventionally been a dead space, as a three-dimensional warehouse for draining and short-term storage of aquatic plants, etc. It is an object of the present invention to provide a drying device using solar heat, which is configured to make effective use of the space occupied by the drying device, and on the other hand, to quickly and efficiently dry aquatic plants and the like using solar heat.

(Structure and Effects of the Invention) In order to achieve the above object, the drying device of the present invention makes the back space of the solar M heat collector waterproof and has a ventilation shield or similar ventilation. In the same space, a conveyor-structured shelf with the ability to convey in a certain direction is installed approximately horizontally in the required number of stages, and on these shelves, a large number of draining baskets containing aquatic plants etc. It is said that they are listed in order.

The aquatic plants that have been brought ashore are placed in a draining basket, placed on the shelves in order from the entrance of the lowest shelf, and advanced in a fixed direction in a progressive manner.

When the drain basket reaches the forward end of the shelf, it is transferred to the upper shelf. At this time, if the volume of the aquatic plants has decreased, an operation such as putting the aquatic plants from two baskets into one basket is also performed. In this way, the drain baskets containing aquatic plants are sequentially advanced to the upper shelf. Then, as the volume decreases, the number of draining baskets is reduced while keeping the volume to a certain level, and the ones that reach the top exit are replaced in the drying room. Therefore, the space behind the solar heat collector is It will be used as a three-dimensional warehouse for draining aquatic plants and storing them for short periods of time. Furthermore, while the transportation process is labor-saving in the multi-storey warehouse, only materials that have been sufficiently pretreated enter the drying room, making the drying process extremely efficient (5) and making subsequent solid fuel processing an integrated industrial process. This will contribute to the practical application of the technology.

(Example) Next, the example shown in FIGS. 2 and 3 will be described. The original structure of the drying device is the same as that shown in FIG. 1, and is indicated by the same reference numerals throughout the figure.

In the figure, numeral 10 denotes a ventilation shield that surrounds the back side space 15 of the solar heat collector 2. Thus, the same back space 15
is formed in a closed space that reliably prevents rainwater from entering and allows air to circulate appropriately. This is a shelf that is installed approximately horizontally and has a conveyor structure such as a rolling conveyor, a chain conveyor, or a belt conveyor.

The shelves 11 are arranged in parallel to fill the entire floor area of the closed space, and have an appropriate margin for the height of the temporary water cutter (p).
6) The building is installed in three levels (however, the number of levels is not limited to this).

The shelves 11 on each level are installed in a running water direction with a common front-lower angle (rear-lower angle is also possible), and a waterproof board 12 is laid on the bottom surface of the shelf. A drainage gutter 13 is provided in the direction of the edge ridge.

Therefore, water droplets dripping onto the shelves 11 of each tier are received by the lower surface of each tier of shelves and are not allowed to drip downward, but are discharged to the outside through the drainage gutter 13 of that tier.

In the figure, numeral 14 is a water-cutting basket that houses a certain amount of harvested aquatic plants t#19 and is placed on the shelves 11 of each stage. Although the shape and structure of this water-cutting basket 14 are arbitrary, it is preferable for handling to have a constant size and shape. In addition, for functionality, the bottom of the basket has a mesh structure that allows water droplets to easily drip.

Therefore, when each shelf 11 has the ability to transport in the directions of the arrows ■, @, and θ in FIG. Nyogo 1
4 from the right end of the lowermost shelf 11 in FIG. 3, and move them sequentially in the direction of the arrow ■.

When placing the water drainer at the left end, either move the drainer @ 14 that has moved forward and place it on the upper shelf 11, or if the volume of the aquatic plants 9 has decreased, for example, combine the aquatic plants from two baskets into one basket. We will also reduce the number of Mizukiri Nyorō baskets.

Then, they are placed on the upper shelf 11 and moved sequentially in the direction of the arrow @.

Thereafter, the same process is applied at each point, and the aquatic plants 9 in the drain basket 14 that have reached the end of the uppermost stage are transferred to the drying chamber 7. At this point, there are no more water droplets attached to the aquatic plants, and they are already drying out at room temperature.

Therefore, the drying process in the drying chamber 7 is carried out rapidly and efficiently.

Thus, in the closed space, aquatic plants 9 are placed on each shelf 11.
Since it is possible to contain and store a large amount of aquatic plants at a high density, there is no need to worry about finding a place to store a large amount of aquatic plants, weighing several hundred to several tons, collected from large lakes and marshes, etc., and is extremely convenient.
