[0005]

DISCLOSURE OF THE INVENTION Waste liquid collector 100
In the above, the lid 102 is in a state in which the pushing operation rod 109 is projected upward, so that the size of the package is large, and a lot of cushioning material for packaging has to be used to prevent damage. I hate getting bigger and bigger. Therefore, there is a problem that the transportation work becomes troublesome and the transportation cost becomes high. In addition, in order to prevent erroneous operation except when in use, the safety holder 12 is attached to the protruding portion of the pushing operation lever 109.
Although 0 was engaged and attached, the manufacturing cost was further increased because of this.

On the other hand, the space formed between the outer peripheral surface of the funnel-shaped inner bottom portion 106 and the cylindrical wall 104 becomes a dead space.
For this reason, there is a problem that waste suction occurs at the start of suction for vacuuming the inside of the waste liquid reservoir 101, the rise until the predetermined negative pressure is reached is delayed, and the time spent for suction (response time) increases. This problem is particularly important when the suction and the stop are performed intermittently. On the other hand, when the waste liquid is full in the waste liquid reservoir 101 and the suction is finished, even when the vacuuming is stopped, the negative pressure in the dead space is about to return to the atmospheric pressure, and the suction of the waste liquid is continued. , The water level of the waste liquid rises beyond a predetermined storage amount.
For this reason, the distance between the liquid surface of the waste liquid and the spray port 110 is close, and the upper surface of the inner plug 112 is formed as a conical surface to improve the dispersibility of the coagulant, but the coagulant is In some cases, it became difficult to disperse and supply the waste liquid and the solidification of the waste liquid was insufficient. The liquid level rises remarkably, and the liquid level is the inside plug 11
2 or reaches the spray port 110, it becomes difficult or impossible to spray the coagulant.

The present invention has been made in view of the above circumstances, and provides a waste liquid recovering apparatus which has a low transportation cost and a low manufacturing cost and which has improved responsiveness at the time of starting and stopping the suction of the waste liquid. The purpose is to do.

[0008]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention comprises a waste liquid reservoir and a lid covered with the waste liquid reservoir,
In the waste liquid recovery device, the lid is provided with a waste liquid receiving pipe and a ventilation pipe communicating with the waste liquid storage device, and a coagulant storage unit with a spray port facing the waste liquid storage device. An operating rod holding the operation receiving portion is provided so as to be pushed down at a position not protruding from the upper surface of the body, and an inner plug for closing the spray port is provided at the lower part of the operating rod.

Further, the present invention is characterized in that an inclined ceiling portion is extended from the lower peripheral edge portion of the lid to the lower peripheral side surface of the coagulant storage portion. The coagulant storage unit may be detachably connected to the central through-hole of the inclined ceiling. A guide wall that surrounds the middle part of the operating rod is provided in the storage part of the lid, and when the operating rod is not operated, the peripheral part of the operating rod and the lower opening edge of the guide wall are in contact with each other without a gap. It is good to leave it.

A bag-shaped internal container that can be stored in the waste liquid reservoir may be attached to the lower surface of the lid in a liquid-tight manner with its mouth facing upward. In this case, at the bottom of the waste liquid reservoir, it is preferable to provide a lower ventilation passage that connects at least two locations on the outer peripheral surface of the bottom and the inside of the container. It is advisable to provide a liquid leak preventer, which swells upon contact with a liquid and blocks liquid permeability, in the ventilation passage of the ventilation pipe.

[0011]

The lid has a structure in which the operating rod does not project, so that the overall volume can be reduced and the packaging can be made smaller. Also, a safety holder is not needed. In the lid,
By providing the slanted ceiling portion, the cylindrical wall parallel to the axial direction of the waste liquid reservoir is eliminated, so that the dead space can be reduced and the response at the time of starting suction and at the time of stopping suction can be improved.

By configuring the coagulant storage portion of the lid body to be detachably connected to the central through hole of the inclined ceiling portion,
It is possible to remove the coagulant storage portion after use to reduce the overall volume, or to replace the coagulant storage portion after spraying the coagulant with a new coagulant storage portion containing the coagulant. In the coagulant storage portion of the lid, when the operating rod has not been operated, the peripheral portion of the operating rod and the lower opening edge of the guide wall are brought into contact with each other without leaving a gap so that the operating rod has entered the guide wall. It is possible to prevent the operating rod from becoming difficult to operate due to the coagulant.

When the inner container is attached to the lid, the waste liquid can be solidified in the inner container, and then the lid and the inner container can be removed from the waste liquid reservoir and discarded. Can be used repeatedly. in this case,
If the lower vent passage is provided at the bottom of the waste liquid reservoir, the inner container can be easily expanded to the inner surface side of the waste liquid reservoir, and the piping can be made easy and smart.

If a liquid leak preventer utilizing the swelling action is provided in the ventilation passage of the ventilation pipe of the lid, the leakage of waste liquid can be reliably prevented.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment of a waste liquid collector 1 according to the present invention, and the waste liquid collector 1 is basically also a waste liquid reservoir 2 and a lid covered with the waste liquid reservoir 2. Body 3

A hook piece 11 used for engaging with the waste liquid reservoir 2 is provided on the outer edge portion 8, and a male screw portion used for coupling with the coagulant storage portion 6 is provided on the outer peripheral surface of the standing wall portion 10. Has been. Further, the ceiling plate portion 9 has two short pipe portions 1
The elbows 1 and 2 are provided in a vertically penetrating manner.
4 and 15 are inserted so that the swing angle can be changed.
By using the elbows 14 and 15 in this manner, the hoses connected to these elbows are prevented from being broken or twisted so that they do not come off or become narrowed. Elbow 1
One of 4 and 15 is used as a waste liquid receiving pipe, and the other is used as a ventilation pipe (intake pipe).

The coagulant storage unit 6 is composed of a funnel-shaped bottom body 18 which constitutes a lower peripheral wall, and a cover body 19 which closes an upper opening of the bottom body 18, and a sprinkling port 20 is provided at the center of the bottom body 18. Is provided. Generally, the bottom body 18 and the cover body 19 are joined together by an appropriate means such as welding by electromagnetic waves or ultrasonic waves, heat welding, adhesion, screwing, press fitting, or fitting so as not to come off. A coagulant storage chamber 17 is formed. On the outer peripheral surface of the bottom body 18,
A female screw cylinder 21 which is externally fitted and is capable of being screwed into the male screw portion is vertically provided on the standing wall portion 10 of the inclined ceiling portion 5. Therefore, the coagulant storage section 6 and the inclined ceiling section 5 are detachably connected. When the two are screwed together, the spray port 20 of the coagulant storage unit 6 is placed inside the central through port 4 of the inclined ceiling part 5.

A shallow circular recess 23 is provided in the center of the upper surface of the cover body 19, and an elliptical recess 24 is provided in the center of the recess 23. Further, a cylindrical guide wall 25 that hangs down into the coagulant storage chamber 17 is provided at the bottom of the elliptical recess 24. An operating rod 26 is inserted through the guide wall 25 so as to vertically pass therethrough. At the upper end of the operating rod 26, there is provided a thin plate-shaped operation receiving portion 28 which is fitted in the circular recess 23 and is substantially flush with the upper surface of the cover body 19 (that is, the upper surface as the lid body 3). ing. Since the planar shape of the operation receiving portion 28 is an elliptical shape that can be fitted into the elliptical concave portion 24, the operation rod 26 is 90 °.
Each time it is rotated, it is possible to switch between a state in which it can descend in the elliptical recess 24 and a state in which it cannot descend. Thirty
Is a knob for rotating the operating rod 26.

When the operation receiving portion 28 is orthogonal to the elliptical concave portion 24 and engaged with the circular concave portion 23, as shown in FIG. 1, the concavo-convex member provided between the operation receiving portion 28 and the circular concave portion 23. The combination means 31 holds the set. This prevents erroneous operation when not in use.
Further, the pressing rod 26 has a structure in which reinforcing ribs project in four directions so as to have a cross-shaped cross section, and the operation receiving portion 28 of the lower reinforcing rib 26a is engaged with the circular recess 23. In the state, the lower opening edge of the guide wall 25 and the upper end of the rib are formed in an amount that allows engagement. Therefore, the pressing rod 26 does not slide upward more than a predetermined amount.

As described above, according to the present invention, the operating rod 26 has the lid 3
Since it does not project upward, it is possible to reduce the size of the packaging, reduce the transportation work, and reduce the transportation cost. Of course, the safety holder 120 that was required in the past
(See FIG. 8) is not necessary, and there is an advantage that the manufacturing cost can be reduced. At the lower end of the operating rod 26, there is provided a conical inner plug 33 capable of closing the spray port 20 when the operation receiving portion 28 is engaged with the circular recess 23. Therefore, by pushing down the operating rod 26, the inside plug 33 can be made to escape downward from the spraying port 20, whereby the coagulant G stored in the coagulant storage chamber 17 can be removed.
It can be scattered and dropped along the upper surface of the taper. Even if the inner plug 33 comes off from the sprinkle port 20, the operation receiving portion 28
Is caught in the elliptical recess 24, so that the inside plug 33 is held in a suspended state.

The inner plug 33 is made of soft resin, rubber or the like, and has a press-fitting hole formed from the top thereof toward a lateral hole 33a formed so as to cross the tapered upper surface. The press-fitting hole has a structure in which the two are joined by being fitted to the protrusion 34 provided at the lower end portion of the operating rod 26. Compared with the manufacturing method by ultrasonic welding or heat welding, The cost is low and the assembly is easy. Further, since the inner plug 33 is formed of soft resin or rubber in this way, the inner plug 33 can be slightly reduced in diameter at the time of fitting to the spray port 20 to enhance the tight plugging property, and a sealing member such as an O-ring is separately provided. No longer needed. This is also useful in promoting lower manufacturing costs and easier assembly. It should be noted that the operability is also lighter than in the case of using the O-ring.

The operation receiving portion 2 is provided in the middle of the operation rod 26.
In the state where 8 is engaged with the circular recessed portion 23, that is, when the inner plug 33 closes the spray port 20, there is provided a flange portion 35 that comes into contact with the lower opening edge of the guide wall 25 without a gap.
For this reason, it is possible to prevent the coagulant G from penetrating into the guide wall 25 and causing clogging or biting, and thus preventing the sliding resistance (operation resistance) from becoming excessive.

Reference numeral 37 is a thin-walled and softened seal tongue piece integrally formed with the operating rod 26, and solidifies through the guide wall 25 or the elliptical recess 24 even when the operating piece 26 is pushed. The agent G is prevented from leaking.
By integrating the seal tongue piece 37 in this way, it is not necessary to separately provide a seal member such as an O-ring, so that the manufacturing cost can be reduced and the assembly can be facilitated.

The waste liquid reservoir 2 is made of a transparent resin material, and a grip portion 39 is provided on the outer periphery of the waste liquid reservoir 2 so as to contradict each other. Engaging holes 40 that penetrate vertically are formed in these grip portions 39, and can engage with the hook pieces 11 of the inclined ceiling portion 5. Reference numeral 41 is a guide piece for inserting the hook piece 11. An annular packing 44 is provided between the outer edge portion 8 of the slanted ceiling portion 5 and the upper opening portion of the waste liquid reservoir 2 to enhance the tight plugging property.

Next, a method of treating waste liquid using this waste liquid collector 1 will be described. A waste liquid suction hose (not shown) is connected to the waste liquid receiving pipe (e.g., elbow 14), and a vacuum hose (not shown) connected to a vacuum generator is connected to the ventilation pipe (e.g., elbow 15). Recovery work. When the inside of the waste liquid reservoir 2 is to be evacuated, the inclined ceiling portion 5 connects the portion of the coagulant storage portion 6 close to the spray port 20 and the upper opening of the waste liquid reservoir 2.
Dead space is made as small as possible. Therefore, wasteful suction in the initial stage of suction is suppressed to the minimum limit, delay in rising does not occur, and response time becomes small. Further, even when the suction is completed, the suction of the waste liquid is promptly stopped by stopping the evacuation, and it is possible to suppress the unnecessary rise of the liquid surface which impairs the sprayability of the coagulant.

After the waste liquid reservoir 2 is filled with a predetermined amount of waste liquid, a finger is put on the knob 30 of the operation receiving portion 28 to rotate it 90 °, and then the operation receiving portion 28 is elliptical recessed. Push down into 24. As a result, the inner plug 33 is set to the spray port 2
After being removed from 0, it becomes suspended, and the coagulant G in the coagulant storage chamber 17 is sprayed radially along the taper upper surface of the inside plug 20 to coagulate the waste liquid in the waste liquid reservoir 2.

If the waste liquid has a high viscosity and the coagulant is not sufficiently spread in the waste liquid, or if the coagulant is insufficient for achieving a predetermined coagulation state, the used coagulant storage unit 6
Then, the new coagulant storage unit 6 containing the coagulant may be screwed to the inclined ceiling 5 and the above operation may be repeated. Further, even when it is desired to add an appropriate medicine such as a bactericide, this method can be applied by using the coagulant storage unit 6 containing a predetermined medicine. Even if such an operation is performed, there is almost no danger of the operator directly touching the waste liquid, and therefore the risk is extremely low. When the risk of waste liquid is low, the used coagulant storage unit 6 can be removed and the removed empty coagulant storage unit 6 can be discarded as general waste. By doing this, transportation related to incineration, fuel,
In addition to saving time waste, the resources (coagulant storage section 6) can be effectively used by collecting and reusing them.

After the waste liquid is solidified, the central through-hole 4 of the slanted ceiling portion 5 is fitted with a sealing lid (not shown) with the coagulant storage portion 6 still attached or when the storage portion 6 is removed. Then, the waste liquid reservoir 2 is incinerated together with the inclined ceiling portion 5. Figure 4
Shows a sloping ceiling portion 5 used in the second embodiment of the present invention, and is different from that of the first embodiment in that a bag-shaped inner container 50 is liquid-tightly attached to the inner lower portion of the outer edge portion 8. There is a point. The inner container 50 is made of a flexible soft resin material and has a size that can be stored in the waste liquid reservoir 2. The inner container 50 is attached to the inclined ceiling portion 5 by electromagnetic waves or ultrasonic waves. By welding, heat welding, adhesion, etc.

In the case of this embodiment, after the waste liquid is collected and solidified, the lid body 3 or the inclined ceiling portion 5 and the inner container 50 may be discarded as they are. Therefore, not only the coagulant storage unit 6 but also the waste reservoir 2 can be reused, which is economical. Since the inner container 50 is foldable, it has an advantage that it can be easily transported, stocked, and managed during the manufacturing process.

In this embodiment, a vacuum hose connection port (not shown) is provided at an appropriate position of the waste liquid reservoir 2 so that a negative pressure is applied between the waste liquid reservoir 2 and the inner container 50, and the inner container 5
0 is expanded to the inner surface side of the waste liquid reservoir 2.
Further, when the inner container 50 is provided, the waste liquid reservoir 2 and the lid 3 need to be attached and detached, but since a negative pressure is created between the waste liquid reservoir 2 and the inner container 50, the waste liquid reservoir 2 and Lid 3
Since they are firmly adhered to each other via the packing 44, the connection between them is merely a fitting structure, and the hook piece 11 (see FIG.
(See) is not provided.

On the other hand, in this embodiment, as the ventilation pipe, a ventilation pipe 52 having a liquid leakage preventive device 51 is used instead of the elbow 15 described above. This liquid leak preventer 51
Has breathability that does not cause resistance in the pipeline when dry, but comes in contact with liquid (that is, when waste liquid begins to overflow)
The fiber material 53 that swells and blocks the liquid permeability is incorporated. As the liquid leak preventer 51, Japanese Patent Laid-Open No. 5-20
The material disclosed in Japanese Patent No. 1452 can be used, and as the fibrous material 53, a fibrous base material made of acrylic fiber or the like and a water-absorbing polymer substance (for example, sodium polyacrylate) adhered thereto or , Composed of fibers formed of the water-absorbing polymer substance. By using such a liquid leak preventer 51, for example, even a waste liquid having a high viscosity (diffusive in diffusivity) has an advantage that water can be stopped promptly and reliably, and environmental pollution due to leakage of the waste liquid can be prevented. . Incidentally, 54 is a waste liquid dispersion plate for dispersing the waste liquid flowing into the liquid leak preventer 51 around the lower surface of the fibrous material 53, and is attached at a predetermined interval facing the inflow port. By providing such a waste liquid dispersion plate 54, a water blocking action can be quickly obtained, and the water blocking action is improved as compared with the case where the waste liquid dispersion plate 54 is not provided. The effect is obtained, and the fiber material 53 can be thinned.

5 to 7 show a waste liquid reservoir 2 used in the third embodiment of the present invention. The waste liquid reservoir 2 is shown in FIG.
Is used when using the inner container 50 described in the second embodiment, and the lower ventilation passage 55 is provided on the lower surface side of the bottom portion. In the lower ventilation passage 55, two openings 56 and 57 are formed on the outer peripheral surface of the bottom of the waste liquid reservoir 2, both openings 56 and 57 communicate with each other in a U-shape, and a U-shaped communication section. A groove-shaped opening 58 communicating with the inside of the waste liquid reservoir 2 is formed midway.

With such a construction, the vacuum hose is connected to one of the openings 56 and 57 on the outer peripheral surface side of the bottom, and the other is closed, for example, whereby the expansion of the inner container 50 is promptly performed. It can be carried out. In this case, since the suction action is downward, the effect that the inner container 50 is inflated efficiently can be obtained. Further, since the pipe is located closer to the bottom, the appearance is improved, and the stability of the waste liquid reservoir 2 is improved.

Since the waste liquid reservoir 2 of this embodiment is premised on not being discarded, it does not affect the running cost even if it has a complicated structure. Therefore, the mounting hook body 60 is provided on the outer peripheral surface. It has an attached structure so that it can be conveniently used. Further, the hook body 60 is provided with a spare short pipe 61 vertically extending therethrough. This spare short pipe 61 is, for example, as shown in FIG. 7, when using a plurality of waste liquid collectors 1 and 1 at the same time,
In order to improve the fit of the communication hoses 63 and 64 in order to make one of the openings 56 and 57 of the lower ventilation passage 55 and one of the elbows 14 and 15 of the lid 3 communicate with each other. Can be used. The communication hoses 63, 64
In the waste liquid collector 1 on the left side provided with the above, by using a ventilation pipe provided with the liquid leak preventer 51 instead of the elbow 14, the waste liquid overflowing from the waste liquid collector 1 flows into the communication hose 64. It is possible to prevent this from occurring, and it is possible to prevent the inside of the intake pipe from being contaminated.

The detailed structure and shape of the present invention can be appropriately changed other than the above.

[0037]

According to the present invention, which has the above-described structure and has the structure in which the operating rod does not project in the lid, the packaging can be made compact. Further, since it is not necessary to consider the damage prevention of the operating rod at the time of packaging, the cushioning material for packaging can be small, and a safety holder or the like for preventing erroneous operation is also unnecessary. As a result, the transportation work is simplified and the transportation cost can be reduced.

If the lid body is provided with the inclined ceiling portion, it is possible to reduce the dead space, improve the responsiveness at the time of starting and stopping the suction of the waste liquid, and start the suction. It is possible to prevent a delay in response time due to wasteful suction at the time and unnecessary inflow of waste liquid at the end of suction. By allowing the lid to be disassembled into a sloping ceiling and a coagulant storage, not only can additional use of coagulant and reuse of the coagulant storage be done, but energy waste related to incineration can be eliminated. It will be possible.

The lid is provided with a guide wall surrounding the middle portion of the operating rod, and when the operating rod is not operated, the peripheral portion of the operating rod and the lower opening edge of the guide wall are brought into contact with each other without a gap. By setting it, it is possible to prevent deterioration of operability due to invasion of the coagulant into the guide wall, clogging, and the like. If the inner container is attached to the lid, the waste liquid reservoir can be reused and the cost can be reduced. In this case, if a lower ventilation passage is provided at the bottom of the waste reservoir, the piping can be made easy and smart.

If a liquid leak preventer utilizing the swelling action is provided in the ventilation passage of the ventilation pipe of the lid, the leakage of the waste liquid can be surely prevented.
