Abstract

PURPOSE:To make crushed ice conveyable so efficiently with a simple structure, by mixing the crushed ice with water and making it into a fluid, while conveying it through a volute pump. CONSTITUTION:Crushed ice is stored inside a conveying device body 1 in advance, and a screw conveyor 4 is rotated by a motor 3 whereby the crushed ice is fed to a suction port 7 of a volute pump 6 while smashing it into proper pieces. Successively, the crushed ice is mixed with water out of an injection pipe 10, making it into a fluid, then it is fed to the volute pump 6 under pressure, and vonveyed up to a spot of destination inside a feed pipe 11 after passing through a check valve 9. At this time, a mixture ratio between the crushed ice and the water is adjusted by a flow regulating valve 12. According to this method, the crushed ice is conveyable efficiently with a simple structure.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for transporting crushed ice using a volute pump.

Conventionally, crushed ice used on fishing boats is stored in fish holds and piled up on the deck using mokko, etc.

The fish are manually loaded into the fish hold along with the fish.

This submersion work requires breaking the ice that has melted together on the slippery deck to evenly submerge the fish hold, which is hard work for the deck workers and is extremely tiring.
It was also highly dangerous.

In order to mechanize this submersion work, various crushed ice conveying devices using the pneumatic conveying method have been commercialized, but none of them have become widespread.

The reasons for this are as follows: (a) Due to poor transport efficiency, the power source becomes large and energy consumption becomes enormous.

(b) Since the power section and the entire device are large, installation is difficult and requires major construction, especially on a ship, which increases installation costs and makes the ship narrow, which tends to hinder all kinds of work.

C. Cold blockage in the transport route is likely to occur due to the phenomenon of re-freezing of crushed ice, and if one end is blocked, extensive restoration work is required, and the reliability of the equipment is extremely low.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and provide a highly efficient and reliable method and apparatus for transporting crushed ice.

The present invention will be explained with reference to the drawings. First, to explain the apparatus of the present invention, FIG. 1 is a side view (partially sectional view) showing a first embodiment of the apparatus of the present invention.

1 shows the main body of the conveying device, with the top open.

A screw conveyor 4 that can be rotated by a motor 3 is installed inside the par 2, and the suction lower of a volute pump B is attached to the discharge port 5 of the screw conveyor 4, and a check valve 9 is attached to the discharge port 8 of the volute pump B. will be established.

The suction lower of the volute pump B is provided with a water injection pipe 10 that can inject water into the interior of the suction lower.

11 is a conveying pipe, and 12 is a flow rate regulating valve.

Next, a method of using the first embodiment of the crushed ice conveying apparatus of the present invention and a first embodiment of the crushed ice conveying method of the present invention will be described.

Crushed ice is stored inside the hopper 2, and the motor 3 is driven to rotate the screw conveyor 4 to send the crushed ice inside the hopper 2 to the suction lower of the volute pump B.

At this time, the crushed ice that is fused together to form a large lump is crushed by the screw conveyor 4, and is made into an appropriate size that can be transported.

The crushed ice that has entered the suction lower is mixed with water by the water flow injected from the water injection pipe 10, and the crushed ice and water become a fluid and are pumped by the volute pump B, passing through the check valve 9 and destined for transport '1f11. It will be transported to the location.

The mixing ratio of crushed ice and water is adjusted by the flow rate adjustment valve 12, and the minimum ratio of crushed ice to water is 8:2 to 7:3.
This is the minimum value at which crushed ice and water can be transported as a fluid; if the amount of water is smaller than this, the properties as a fluid will essentially disappear, making transport by a volute pump impossible.

In order to minimize the melting of crushed ice, it is desirable to use cooled water or seawater as the injection water.

At this time, as shown in FIG. 2, the cold water is sent from the cold water tank 14 to the water injection pipe 10 by the water supply pump 13, and the cold water transported by the transport pipe 11 is separated from crushed ice by the separator 15 and returned to the return pipe 16.
By returning the cold water to the cold water tank 14, the amount of cold water can be kept to a minimum.

Also, as shown in Figure 6, the intended place for transporting seafood is 17.
In this case, if the cold water in the fish hold 17 is used as injection water,
Since the cold water is circulated, the amount of cold water can be saved.

FIG. 4 is a plan view showing a second embodiment of the crushed ice conveying device and a second embodiment of the crushed ice conveying method according to the present invention. In the second embodiment, the water injection pipe 10 is provided on the side plate 2 of the hopper 2. This allows mixing of crushed ice and water while canceling the bubbling and jigging phenomenon of crushed ice inside the hopper 2 by injecting water through the water inlet pipe 10. By providing a plurality of water inlets, in the case of the first embodiment, crushed ice and water can be evenly mixed, and in the second embodiment, it is possible to effectively eliminate the oozing phenomenon.

As described above, according to the present invention, broken ice can be transported with a simple structure, which improves the efficiency of casting and transport operations, reduces running costs, and saves labor and labor, especially in fishing. This will make a major contribution.
