Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a boiler for use in continuously boiling small fish, which is a material for boiled and dried, in a large amount, and more particularly to an apparatus for circulating boiling water.

[0002]

2. Description of the Related Art In general, a boiling pot for making boiled dried vegetables is
It consists of a shallow bath with a rectangular shape of about 2m x 4m in plan view. The inside of the hot tub forms a series of hot water flow paths defined by a partition wall and has a continuous start and end. The hot water put in the hot water flow path is heated by a steam pipe provided in the partition wall and is driven by a propeller. It is configured to be forcibly circulated. Then, the small fish, which is the dried material, is put into the hot water flow path from the feeding conveyor, boiled while flowing along with the hot water, and scooped out of the hot water tank by the take-out conveyor.

As shown in FIG. 8, the propeller is provided with a drive shaft 95 disposed along a flow in a hot water flow path 94 formed between a side wall 92 of a hot water tank 91 and a partition wall 93. Supported by The drive shaft 95 is connected to the side wall 9.
2 and extends to the outside of the bathtub 91, and is connected to a four-pole AC motor 96 arranged outside the bathtub 91.

[0004] On the other hand, in this type of boiling pot, in the boiling water flowing through the boiling water flow path 94, lye (duck) caused by fish fat or the like coming out of small fish used as a material for boiled and dried garbage mixed during fishing. (Hereinafter, simply referred to as fish fat) adheres to the propeller 90,
Cavitation and abnormal vibration may occur. Therefore, an operation of periodically removing fish fat adhering to the propeller 90 is essential.

[0005]

However, in order to remove fish fat from the propeller 90 disposed in the hot water flow path 94, the operation cannot be performed in high-temperature hot water, so that the propeller 90 is temporarily removed from the hot water. It was necessary to take out or to draw out hot water and cool the whole, and the work of making the dried-up had to be stopped for a long time. In addition, a large amount of hot water must be removed from the hot tub 91 during the work, and not only is the thermal loss large, but also time and heat energy are required to reheat the hot water even when the work is resumed. This was one of the factors that increased the manufacturing cost.

[0006]

An object of the present invention is to provide an endless hot water passage formed by partitioning the inside of a hot tub by a partition wall, and providing a conveyer for taking in and taking out the boiled material in the hot water flow passage. In a boiling pot of a type in which the dried material put into the hot water flow path from the input conveyor and boiled while flowing to the takeout conveyor, a propeller for flowing the hot water in the hot water flow path, and an electric motor for driving the propeller, and This problem is solved by providing a propeller unit having a hot water duct surrounding the outer periphery of the propeller, and rotatably supporting the propeller unit in the hot water tank so that the propeller can be pulled up from the hot water tank together with the hot water duct. .

In this case, the propeller unit is constituted by connecting a hot water duct and an electric motor, which are spaced apart from each other, by a transmission means on one side thereof, and disposing the hot water duct of the propeller unit inside the side wall. It is preferable that the side wall of the hot tub is attached to the hot tub so that the electric motor is disposed outside the side wall so that the side wall of the hot tub can enter the space. Further, the hot water duct may be immersed in the hot water flow path with the axis of the propeller shaft oriented in the vertical direction, and may have an inlet and an outlet which are directed in different directions at an upper portion and a lower portion.

[0008]

When the propeller unit is mounted on the side wall with the side wall having entered the gap between the hot water duct and the electric motor, the hot water duct is arranged inside the hot water tank and the electric motor is arranged outside. The propeller unit is rotated upward with respect to the hot water tank from a position where the propeller is immersed in the hot water, so that the propeller is pulled out of the hot water flow path. When the hot-water duct is immersed in the hot-water channel, the hot water in the hot-water channel is sucked into the hot-water duct by the rotation of the propeller, and is pushed out from the outlet. As a result, the flow energy of the hot water in the hot water flow path is given.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 10 denotes a boiling pot apparatus according to the present invention. The boiling pot device 10 has a bathtub-shaped bathtub 11 made of stainless steel.
1 is provided with a hot water channel 13 formed by partitioning the inside with a partition wall 12. A plurality of hot water flow paths 13 are arranged in parallel along the longitudinal direction, are folded at both ends, and are connected so as to have a start end and an end end, that is, a so-called endless configuration. 1
Reference numeral 5 denotes a charging conveyer that protrudes above the hot water flow path 13, and small fish, which is a material for the dried and dried, is supplied into the hot water flow path 13. Reference numeral 16 denotes a take-out conveyor for scooping the small fish boiled from the hot water flow path 13.

Reference numeral 20 denotes a propeller unit, which is provided for forcibly flowing and circulating hot water in the hot water flow path 13. The propeller unit 20 is connected to the hot tub 1 by the hinge 21.
At one corner, it is pivotally supported so as to be vertically rotatable. As shown in FIG. 5, the propeller unit 20 has a rectangular tubular hot water duct 22 supported inside the side wall 11a of the hot tub 11 by the hinge 21 and an AC motor 23 supported outside. The hot water duct 22 and the AC motor 23 are connected on the upper side by a connection frame 27,
Between the hot water duct 22 and the AC motor 23, a space 20a having a width slightly larger than the thickness of the side wall 11a is left.

A propeller 25 attached to a drive shaft 24 is rotatably supported in the hot water duct 22 via bearing members 29 and 29. The drive shaft 24 is the belt 2

An operating lever 28 is attached to the connecting frame 27 of the propeller unit 20. The operating lever 28 is lifted up by hand, so that a hot water duct as shown in FIG. From the hot water shown in FIG.
1 can be rotated about an axis. B is a hook bar for holding the propeller unit 20 at the raised position.

When the propeller unit 20 is rotated toward the hot water flow path 13 and the hot water duct 22 is sunk vertically in the hot water flow path 13 as shown in FIGS. Since the width of the duct 22 is made slightly narrower than the width of the hot water flow path 13, the hot water flow path 13 is
2 where the horizontal water flow is temporarily blocked.

On the other hand, a hot water inlet 22a is provided on the lower surface of the hot water duct 22, and an outlet 22b is provided on the upper portion.
Hot water is sucked from the inflow port 22a and pushed out into the hot water flow path 13 from the outflow port 22b. Therefore, in the hot water duct 22, a water flow that flows upward from below is generated, and the hot water in the hot water flow path 13 is returned to the hot water flow path 13 again by the propeller 25 and circulates again as a horizontal flow.

The boiler apparatus implemented in the above-described embodiment is configured such that when fish fat adheres to the inner surface of the hot water duct 22 forming part of the hot water flow path 13 or the propeller 25, the operating lever 2 is turned on.
7 to move the propeller unit 2 onto the hot water shown in FIG.
Raise 0. When the bearing members 29 are removed from the hot-water duct 22 after the hot-water duct 22 has cooled, the drive shaft 24 and the propeller 25 can be pulled out from the hot-water duct 22 in the axial direction. Therefore, the drive shaft 24 and the propeller 25 can be cleaned without removing the hot water in the hot water tank 11.

[0016]

According to the first aspect of the present invention, since the propeller is integrated with the drive shaft and the electric motor as a propeller unit and is independent of the hot water tank, the propeller is taken out of the hot water without draining the hot water in the hot water tank. The maintenance and inspection of the propeller and the drive shaft can be performed, and the maintenance and inspection work can be performed in a short time. According to the second aspect of the present invention, the propeller and the electric motor constituting the propeller unit are arranged inside and outside the hot water tank, so that the electric motor is not exposed to the heat of the hot water although they are integrated. However, the thermal load on the motor does not increase. According to the third aspect of the present invention, it is possible to arrange the propeller and the electric motor inside and outside the hot tub, and it is possible to integrate them into a propeller unit. And so on.
