By the way, since the storage tank 100 is provided with a lid 102 such as a metal plate, it is difficult to confirm the amount of waste liquid inside the storage tank 100 from the outside, and eventually the lid 102 is opened for storage. It was confirmed by directly visually observing the inside of the tank 100. This work involves a risk of dropping into the storage tank 100, and since the inside of the storage tank 100 is dark, it is difficult to grasp an accurate liquid level in the storage tank 100, and the storage tank 100 is often used. This caused a situation where the waste liquid overflowed from 100.

[0004]

As described above, when the waste liquid overflows from the storage tank 100 once, the floor in the factory is flooded and slippery, which is not preferable for safety, and personnel are required for cleaning the overflowed waste liquid. This is not preferable in terms of production efficiency.

In order to solve such a problem, it is possible to connect drainage pipes to each of the storage tanks 100, 100 ... By providing a drainage facility for discharging the waste liquid to the outside of the factory by a pump or the like. If a new drainage facility is installed in the currently operating factory, it will cost new capital investment, and at the worst case the production line must be stopped due to the construction of drainage pipes and pumps. The problem of occurs.

The present invention has been made in view of the above problems, and proposes a device having a very simple structure for informing the full-filling time of a storage tank installed on a floor in a factory. It is an issue.

[0007]

In order to solve the above-mentioned problems, the present invention has the following constitution. The invention according to claim 1 is a full water informing device for informing the fullness of a storage tank, wherein a float that follows the vertical movement of the liquid level is guided to the back surface of the lid that covers the inlet of the storage tank. And a guide means for operating the float, an indicating means is provided on the head of the float, and the lid is provided with an opening through which the indicating means can protrude.

According to the full water alarm device of the first aspect, the float for indicating the storage amount of the storage tank is guided by the guide means provided on the back surface of the lid of the storage tank inlet, and the liquid level of the storage tank is reached. It moves up and down as it moves up and down. Further, the head of the float is provided with an indicating means, and the indicating means can protrude from the opening provided in the lid. It is possible to easily check whether the storage tank is full or not by visually observing. Further, since the head of the float is provided with, for example, a spherical or projecting indicating means capable of protruding from the opening, when the storage tank approaches a full state,
This indicator is in a state of popping out (protruding) from the opening of the storage tank to call attention to the user, reducing the risk of overlooking the instruction means and more effectively reporting the full state of the storage tank. It becomes possible to do.

According to the second aspect of the invention, the guide means is provided vertically, the float has a predetermined height in the vertical direction, and the diameter of the opening is smaller than the width of the float. The full water alarm device according to claim 1, wherein the threshold is larger than the width of the indicating means.

According to the full water alarm device of the second aspect, since the float has a predetermined height in the vertical direction, the float rises as the liquid level rises and comes into contact with the back surface of the lid of the storage tank. It will be possible to set up a grace period from the beginning to the time when the storage tank is completely filled with water.

Further, since the diameter of the opening is set to be smaller than the maximum width of the float in the horizontal direction and larger than the maximum width of the indicating means in the horizontal direction, the storage tank approaches a full state and the float is covered with the lid. Even if the back surface of the float comes into contact with the floor, only the indicating means projects on the floor surface, and the float is not blocked by the opening and does not project more than necessary, so that walking on the floor is not hindered. .

A lid 2 is provided at the inlet of the storage tank 1 so as to cover the inlet, and a full water alarm device 3 of the present invention is provided on the back surface of the lid 2 (the surface on the inner side of the storage tank). In the present embodiment, the full water notification device 3
Is a hollow cylindrical pipe 4 which is a guide means fixed vertically downward by welding to the back surface of the lid 2, and is housed inside this pipe 4, and is driven by the vertical movement of the liquid level of the waste liquid in the storage tank 1. Then, a cylindrical float 6 that moves up and down in the pipe 4
And a spherical indicator 7 which is a pointing means provided at the center of the upper bottom surface of the cylindrical float 6.

Further, in order to confirm the positions of the float 6 and the indicator 7 and to circulate the atmosphere between the inside of the pipe 4 and the outside world and to ensure the smooth vertical movement of the float 6, the lid 2 has a circular shape. The opening 8 is provided, and the pipe 4 is installed so that the peripheral edge thereof concentrically surrounds the opening 8. The diameter of the opening 8 is larger than the diameter of the indicator 7 and smaller than the inner diameter of the pipe 4. Therefore, when the storage tank 1 is near full water, only the indicator 7 protrudes from the opening 8,
The body of the float 6 is stopped on the back surface of the lid 2 around the opening 8,
Since it does not project from the opening 8, it does not hinder walking on the floor.

Further, there is not much waste liquid accumulated in the storage tank 1, and the float 6 is provided between the liquid surface of the waste liquid and the bottom of the pipe 4.
A drop stopper 5 is provided near the bottom of the pipe 4 to prevent the float 6 from falling out of the bottom opening of the pipe 4 when there is a space equal to or higher than the height. Further, FIG. 2 shows a perspective view of the lid 2 of the storage tank 1 in a state where the full water notification device 3 is provided, as seen from the outside. Lid 2
Is provided with an opening 8, and the periphery of the opening 8 is painted in a bright color to indicate that the full water alarm device 3 is present, and the word "full water alarm" is drawn. There is.

The individual components of the full water alarm device 3 of the present invention will be described below. The length of the pipe 4 is not particularly limited, but it is desirable that the length of the pipe 4 does not hinder the opening and closing of the lid 2. Further, in the present embodiment, a hollow cylinder is used as the pipe 4, but the pipe 4 can accommodate the float 6 inside,
The present invention is not limited to this as long as the float 6 can be guided along with the vertical movement of the liquid surface of the waste liquid.
It may be in the form of a cylindrical basket or the like made by assembling thin pipes.

When a hollow cylinder is used as the pipe 4, the inner diameter of the pipe 4 is not particularly limited, but since the float 6 moves up and down in the pipe 4, the float 6
It is desirable that the diameter of the indicator 7 be smaller than the diameter of the float 4, and that it is desirable that the indicator 7 has a gap between the inner wall of the pipe 4 and the side surface of the float so as not to be displaced from the opening 8. The material of the pipe 4 is also not particularly limited, but since it comes into direct contact with the waste liquid, it is desirable to use a material having excellent corrosion resistance such as stainless steel or polyvinyl chloride.

Further, in the present embodiment, the atmosphere is circulated between the inside of the pipe 4 and the outside through the opening 8 provided in the lid 2, but for example, the pipe 4 near the joint with the lid 2 is used.
It is also possible to circulate the atmosphere inside and outside the pipe 4 by providing a suitable ventilation hole on the outer circumference of the pipe or by providing a slit of a suitable width along the longitudinal direction on the side surface of the pipe 4.

Further, in the present embodiment, the pipe 4
The pipe 4 and the back surface of the lid 2 are joined by welding.
The joining between the lid 4 and the back surface of the lid 2 is not limited to welding as long as the pipe 4 does not drop from the lid 2 and the pipe 4 can reliably guide the float 6. Specifically, the pipe 4 is joined to the back surface of the lid 2 by using bolts and nuts, the female engagement mechanism is provided on the back surface of the lid 2, and the male engagement provided on the upper opening periphery of the pipe 4 is engaged. It is conceivable that the pipe 4 is joined by fitting the mechanism to the female engagement mechanism.

In this way, the pipe 4 is detachably joined to the lid 2, so that the inside of the full water notification device 3 becomes dirty and the movement of the float 6 is hindered.
Can be removed from the lid 2 for cleaning.

The height of the float 6 in the vertical direction determines a grace period from when the indicator 7 protrudes from the opening 8 to notify the fullness of the water until the storage tank 1 becomes completely full. It is desirable to determine in consideration of the rising speed of the liquid level of the waste liquid in the tank 1. In addition,
The “full water notification” means that the storage tank 1 approaches the full water state and the indicator 7 projects from the opening 8.

If the height of the float 6 in the vertical direction is increased, even if the rising speed of the liquid level of the waste liquid in the storage tank 1 is high, from the notification of full water until the storage tank 1 becomes completely full. It is possible to secure a sufficient grace period. On the contrary, when the rising speed of the liquid level of the waste liquid in the storage tank 1 is small, even if the height of the float 6 in the vertical direction is reduced,
It is possible to secure a sufficient grace period from the notification of full water until the storage tank 1 becomes completely full.

In the present embodiment, the polystyrene foam resin formed into a cylindrical shape is used as the float 6, but the float 6 can float on the waste liquid and is not corroded by contact with the waste liquid. , But is not limited to this.
For example, it may be made of a hollow resin or metal formed into a predetermined shape. Further, it is desirable that the volume of the float 6 is a volume that does not lift the lid 2 even when the storage tank 1 is full of water and the buoyancy of the float 6 is maximum.

The indicator 7 provides a full-filling notification when the storage tank 1 is almost full, so that the indicator 7 has a certain height above the surface of the lid 2 so that the user can easily recognize the notification. It is desirable to project. Since the indicator 7 projects from the surface of the lid 2, the indicator 7
Can be recognized from all directions on the floor, and it is possible to more effectively notify the storage tank 1 of full water.

Further, since the indicator 7 protrudes from the opening 8 to notify the user that the water is full, it is desirable that the indicator 7 be colored in a conspicuous manner so that the user can easily recognize the notification. For example, it is conceivable to color the opposite color to the color of the environment (floor, wall surface, etc.) in which the storage tank 1 is installed (FIG. 2).

Further, since the indicator 7 projects from the surface of the lid 2, it is desirable that the indicator 7 has a shape such that the projecting portion does not hinder walking or the like. In particular,
It is desirable that the protruding portion does not have a corner that causes tripping during walking and that the shape is gentle. For example,
A spherical shape, a hemispherical shape, or the like as used in this embodiment can be considered.

Further, the indicator 7 is preferably joined to the float 6 so as not to be separated from the head of the float 6 due to a collision of shoes or the like while walking while protruding from the lid 2. Specifically, it is conceivable that the indicator 7 is joined to the float 6 with a strong adhesive, or mechanically joined by a pin or the like that penetrates the indicator 7 and reaches the float 6. Further, in the present embodiment, the indicator 7 is provided separately from the float 6, but it is also possible to form the head of the float 6 into a convex shape and use the convex portion as the indicator 7.

In the present embodiment, the opening 8 provided in the lid 2 is a circular hole. The diameter of the opening 8 is preferably larger than the diameter of the indicator 7 so that the indicator 7 can project, and smaller than the diameter of the float 6 so that the float 6 does not project above the floor.
By setting the diameter of the opening 8 in this range, even if the storage tank 1 is in the vicinity of the full state, only the indicator 7 protrudes from the surface of the lid 2 and the main body of the float 6 does not jump out onto the floor. It does not interfere with.

The opening 8 does not need to be circular as in the present embodiment, and the indicator 7 can smoothly project from the opening 8 to prevent the float 6 from projecting from the surface of the lid 2. If so, the shape is not particularly limited. Specifically, an elliptical shape and a quadrangular shape can be considered. In addition, a special display may be provided on the surface of the lid 2 (the surface on the floor side) around the opening 8 in order to call the user's attention. For example, it is possible to display characters such as "full water warning" around the opening 8.

The drop stopper 5 provided near the lowermost portion of the pipe 4 has a low liquid level of the waste liquid in the storage tank 1 and a space equal to or higher than the height of the float 6 is provided between the bottom of the pipe 4 and the liquid surface. In this case, it is a member for preventing the float 6 from falling off the pipe 4.

In the present embodiment, a split pin provided so as to cross the center of the pipe 4 is used as the fall stop 5. The shape of the fall stopper 5 is not limited as long as it does not prevent the waste liquid from flowing into the pipe 4 and can prevent the float 6 from falling. For example, a coarse wire mesh is provided at the bottom of the pipe 4, a rod or plate-shaped member is projected from the side wall near the bottom of the pipe 4 toward the inside of the pipe 4,
It is conceivable to cover the bottom of the cap with a cap having an opening smaller than the diameter of the float 6 and having a size that does not prevent the inflow of the waste liquid into the pipe 4. Needless to say, since the fall stop 5 is in direct contact with the waste liquid, it is desirable that it be formed of a material having corrosion resistance.

The indicator 7 is located at the bottom of the pipe 4 by its own weight and is supported by the fall stop 5.

FIG. 3B is a schematic diagram showing a state in which the amount of waste liquid in the storage tank 1 is increased and the liquid level is higher than the bottom of the pipe 4. When the liquid level of the waste liquid becomes higher than the bottom portion of the pipe 4, the atmosphere in the pipe 4 flows out to the outside through the opening 8, and the liquid level inside the pipe 4 becomes equal to the liquid level of the storage tank 1. The float 6 and the indicator 7 float on the waste liquid inside the pipe 4 and rise in the pipe 4 as the liquid level of the waste liquid rises.

FIG. 3C is a schematic diagram showing a state in which the waste liquid in the storage tank 1 is accumulated up to near the full state. When the liquid level of the waste liquid in the storage tank 1 continues to rise, the float 6 and the indicator 7 floating on the waste liquid are guided by the pipe 4 and accordingly rise gradually. Eventually, when the liquid level of the waste liquid reaches a predetermined height, the upper bottom surface of the float 6 comes into contact with the back surface of the lid 2, and further rise of the float 6 is suppressed,
The indicator 7 projects from the opening 8 and notifies the user of full water. Once the full water notification is made, even if the liquid level of the waste liquid rises, the float 6 and the indicator 7 do not rise any further. Therefore, if the full water notification is made, the user can appropriately fill the storage tank 1 It is necessary to pump out the waste liquid inside with a tank truck.
