Abstract

PURPOSE:To automatically throw in a chemical agent corresponding to the up and down movement of a liquid level, by providing a floater having a float and a throwing-in means engaged therewith so as to freely move the same upwardly and downwardly corresponding to the liquid level. CONSTITUTION:A floater 10 having a float 10b capable of being moved upwardly and downwardly corresponding to the movement of a liquid level such as a water level 13a is provided and a throwing-in means such as a pusher 12 is engaged with the floater 10 in a freely movable manner. By this mechanism, a chemical agent such as a corrosion inhibitor 11 is automatically thrown into the cooling water system of a cooler corresponding to the movement of the liquid level without using hands. This throwing-in mechanism is safe because an electrical means is not used.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feeding mechanism capable of feeding medicine and the like in conjunction with the vertical movement of the liquid level.

Conventionally, most of this type of loading mechanism used electrical means such as magnets and relays. However, if the liquid or atmosphere is explosive or flammable, there is a high risk of explosion due to electrical sparks, etc.
Explosion-proofing was required, but this had the drawback of making the entire device larger and more complex. Furthermore, when the liquid is water, there is a risk of electrical leakage, etc. Therefore, it has been desired to develop a feeding mechanism that can feed medicines etc. in conjunction with the vertical movement of the liquid level without using any electricity.

Therefore, the present invention has a structure in which a floater provided with at least one float is provided so as to be movable in the vertical direction in conjunction with the liquid level, and a charging means is movably engaged with the floater. It is an object of the present invention to provide a charging mechanism that eliminates the above-mentioned drawbacks.

The present invention will be specifically described below based on embodiments shown in the drawings.

FIG. 1 is a schematic diagram showing an example of an automatic loading device to which the present invention is applied.

As shown in FIG. 1, the automatic dosing device 1 has a box-shaped tank 2, and a drain valve 3 is installed at the bottom end of the tank 2.
However, a liquid injection valve 5 is connected near the upper end of the tank 2. A U-shaped siphon 6 has a liquid suction port 6 in the tank 2.
The siphon 6 is provided with an opening at the bottom of the tank, and the other end of the siphon 6 penetrates the bottom 2a of the tank and is connected to the cooling water system of a cooler (not shown) having a liquid level lower than the bottom 2a of the tank. There is.

A lid 7 is detachably provided on the tank 2, and a floater 10, which will be described later, is attached to the lid 7. A guide rail 9, which together with the bushing 12 constitutes the loading mechanism 8 according to the present invention, is provided so as to pass through the lid 7 in the vertical direction. A guide groove 9a is formed in the guide rail 9 in the directions of arrows A and B, that is, in the vertical direction in the figure.A floater 10 is formed in the guide groove 9a, and rollers 10a and 1 are rotatably supported by the floater 10.
They are engaged so as to be movable in the directions of arrows A and B via 0a. At the lower end of the floater 10, a hollow spherical float 10b,
10b is provided together with the balance way) 10c, and a cam groove 10d is formed diagonally in the floater 10. On the other hand, the lid 7 is provided with a guide tube 7a and a cylindrical storage base 7b containing a large number of anticorrosion agents 11 inside. 12 is fitted and engaged so as to be movable in the directions of arrows C and D. The bushing 12 is engaged with a cam groove 10d of the floater 10 via a roller 12a that is rotatably supported at the right end of the bushing 12 in the figure, and is located at a position opposite to the tip 12b of the bushing 12 of the storage base 7b. teeth,
A discharge lower C is formed, and an input lower d is formed to the left of the discharge lower C in the figure so as to penetrate through the lid 7.

Since the present invention 1 has the above-described configuration, when the automatic dosing device 1 is used to inject the corrosion inhibitor 11 into the cooling water system of the cooler at regular intervals, the drain pulp 3 of the tank 2 is first closed. In this state, the liquid injection pulp 5 is opened, and a certain amount of water 13 is injected into the tank 2 via the valve 5 per unit time.
Start the injection. The injected water 13 is stored in the tank 2, and the water level 13a gradually rises, but when the water level 13a rises above a certain level, the floats 10b, 1
0b, the floater 10 receives a buoyant force in the direction of arrow A, that is, upward in the figure, and further moves in the direction A along the guide groove 9a of the guide rail 9 via rollers 10a, 10a in synchronization with the rise of the water level 13a. moving to. Then, the bushing 12, which is engaged with the cam 1lod of the floater 10 via the roller 12a, is pushed out in the direction C by the cam groove 10d, so that the bushing tip 12b is located at the lowest position in the storage base 7b. It comes into contact with the anti-corrosion agent 11 and further pushes out the anti-corrosion agent 11 from the discharge lower C in the direction C.

As the water level 13a is indicated by the dashed line in the figure, the siphon 6
At the position X beyond the top end of the bushing 12, the bushing 12 is pushed out the most in the direction C, and therefore the anticorrosive agent 11 pushed out by the bushing 12 is thrown into the tank 2 from the feeding lower d. On the other hand, when the water level 13a exceeds the top end of the siphon 6, the suction operation of the water in the tank 2 is started from the liquid suction port 6a of the siphon 6, and the water level 13a of the water in the tank 2 is indicated by the chain double-dashed line in the figure. It is discharged and injected into the cooling water system of the cooler until it reaches the position Y shown. When the water level 13a falls, the floater 10 also falls in the direction B due to its own weight, and therefore the floater 12
The tip 12b also moves in the direction D, and the tip 12b retreats to the right side of the storage base 7b in the figure, preparing for the next charging operation. When the water level 13a reaches position Y, the operation of the siphon 6 is interrupted, and the operation of injecting the water 13 in the tank 2 into the cooling water system is interrupted. On the other hand, since a fixed amount of water 13 is always injected from the injected pulp 5, the water level 13a in the tank 2 starts to rise again, and the water flow generated in the tank 2 as water is injected from the valve 5. The anticorrosion agent 11 introduced by the pusher 12 in the previous process starts to dissolve, and by the time the water level 13a reaches position Corrosion inhibitor 11 at an appropriate concentration is injected into the cooling water system together with water 13. Note that the injection interval of the corrosion preventive agent 11 via the siphon 6 is determined by the amount of water injected into the tank 2 via the injection valve 5 per unit time. This increases the injection interval.

In addition, although the above-mentioned embodiment described the case where the dosing mechanism 8 was applied to the automatic dosing device 1 for the anticorrosion agent 11, the present invention is also applicable to the automatic dosing device 1 as well as for applying chemicals, etc. according to the vertical movement of the liquid level. It can be used in all applications where it is necessary to input In addition, it is not necessary that the medicines and the like to be injected by the pusher 12, which is the injecting means, be put into the tank 2.
It is also possible to extend the stroke in this direction and push it out to an appropriate location outside the tank 2. Furthermore, it goes without saying that the object to be thrown in is not limited to medicines, etc., but may be any kind of food, such as food for small birds or small animals.

As explained above, according to the present invention, the floater 10 can move vertically in conjunction with the liquid level such as the water level 13a.
, and the injection means such as the pusher 12 is movably engaged with the floater 10, making it possible to introduce drugs and the like without using any electrical means, thereby reducing the risk of explosions caused by short circuits or electric sparks. This makes it possible to provide a highly safe loading mechanism 8 that does not require explosion-proof treatment or the like.
