Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deodorizing device suitable for use, for example, in a vacuum car that sucks in and transports human waste.

Conventionally, in this type of device, a deodorizing device installed in a vacuum car that inhales and transports human waste, for example, stores the human waste, which is an odor source, inside through a suction pipe 1, as shown in Fig. 1. It consists of a vacuum tank 2 and a deodorizer 4 that guides the odor sucked in by the pump into the interior through a delivery pipe 3 and deodorizes it. contains deodorized water 6 that mainly dissolves and removes hydrogen sulfide components in the odor that is sent into the interior, and also houses activated carbon 7 that absorbs the remaining odor components in the upper part of the water to remove the deodorized gas. It was designed to be discharged to the atmosphere from the exhaust port 5.

In addition, reference numerals 8 and 9° 10 in the figure indicate a water intake cock, a water level adjustment cock, and a drain cock for the deodorized water 6.

However, in such conventional devices, the opening of the delivery pipe 3 in the deodorizer 4 is placed directly above the liquid level of the deodorized water 6, so that the deodorized water is scattered by the dynamic pressure of the odor released from the delivery pipe 3. A part of the activated carbon 7 wets the activated carbon 7 and deteriorates the odor absorbing effect of the activated carbon 7, resulting in an earlier replacement time.

In addition, in the conventional device, the vacuum tank 2 and the deodorizer 4 are always in communication via the delivery pipe 3, and the pressure in the vacuum tank 2 and the pressure in the deodorizer 4 are set to the same pressure. When abnormal pressure occurs in the vacuum tank 2 and increases in pressure, the pressure in the deodorizer 4 will also increase, and especially during the suction operation of the pump, the pressure of the inhaled odor in addition to the abnormal pressure will increase in the deodorizer 4. Therefore, there was a fear that the deodorized water 6 would splash violently and wet the activated carbon 7, making it unusable, or that the deodorizer 4 would be damaged depending on the pressure.

It is an object of the present invention to provide a deodorizing device that eliminates such conventional drawbacks and concerns, prevents deterioration and damage to the deodorizing effect, and allows the device to be made smaller and lighter.

For this reason, in the deodorizing device of the present invention, a delivery pipe that communicates with a vacuum tank is guided into a deodorizer containing deodorized water at the bottom, the end of the delivery pipe is immersed in the deodorized water, and water is discharged from the delivery pipe. In a deodorizing device designed to deodorize odor, a separator plate with an exhaust hole formed in the center is fixed in the middle and high position of the deodorizer, and the inside of the deodorizer is divided vertically into a deodorizing agent chamber and a deodorizing cylinder chamber. A deodorizer is housed in the deodorizer chamber at a distance from the separator, and a single deodorizer tube with a peripheral wall located outside the exhaust hole is installed in the deodorizer chamber, while the deodorizer is placed at a mid-high position on the side wall of the deodorizer. Then, a delivery pipe is introduced into the gap between the lower end of the deodorizer and the separator plate L7, and this delivery pipe is arranged between the deodorizing cylinders and the lower end part through the separator plate, and also between the middle and high parts of the deodorizing cylinder. A partition plate with a flange is provided at the position to divide the inside and outside of the deodorizing cylinder into 1-lower sections, making it impossible for ventilation between the upper and lower inner chambers of the cylinder, and the upper and lower outside of the outside with the upper end closed. The chamber is communicated through the gap formed between the flange and the inner circumferential wall of the deodorizer, while a vent that also serves as a drainage hole is provided on the circumferential surface of the deodorizing cylinder directly above and below the partition plate, and spaced apart from the upper separator plate. The deodorizing tube has a plurality of vent holes that also serve as drain ports on the circumferential surface of the lower half of the deodorizing cylinder, which is substantially immersed in the deodorized water.

The illustrated embodiment in which the present invention is applied to a deodorizing device for a vacuum cleaner that sucks and transports human waste will be described below.
This vacuum tank is designed to store human waste, which is a source of human waste, inside the vacuum tank 11. A connecting pipe 13 is provided in this vacuum tank 11 to guide the odor generated from the human waste to the outside. A switching valve 14 constituted by, for example, a manually operable rotary type directional control valve is connected to the section.

As shown in FIGS. 5 and 6, the switching valve 14 has four ports (Pl, P2) communicating with the hollow interior.

P3. Port P4 is formed as an opening, of which port P1 communicates with the connecting pipe 13, and port P2 and port
P3 communicates with a guide pipe 15, 16 in which a pump P driven by a motor M is inserted, and port P4 communicates with a connecting pipe 17 connected to a valve chamber, which will be described later. P2. P3. P4 is configured to appropriately select a fluid path by a rotary valve 18 that rotates in conjunction with a lever (not shown).

In other words, when inhaling human waste, port 1” Pl and port P
2, and ports P3 and P4 are communicated with each other to guide the odor in the vacuum tank 11 from the connecting pipe 13 to the ports P1 and P2, and the guide pipes 15, 16
connecting pipe 1 by guiding it from port P3 to port P4 via
7, and when excreta is discharged, it is connected to port P1 and port P3 through the switching operation of the switching valve 14.
, and ports P2 and P4 are communicated with each other to allow the pressure air sucked into the valve chamber to flow out from the connecting pipe 17 to the port P2 via the port P4, and the guide pipe 15.16
The human waste is guided from the port P3 to the connecting pipe 13 via the port P1, and is forced into the vacuum tank 11, so that the human waste stored in the vacuum tank 11 is discharged to the outside from the suction pipe 12 along with the odor. There is.

Reference numeral 19 denotes the above-mentioned valve chamber, which is configured as a sealed pressure vessel, and has a valve in the lower part that is normally closed and opens when the pump P is discharged to guide atmospheric air from the suction port 20 into the valve chamber 19. A discharge valve 21, 21 is provided at the upper end to forcefully feed this into the vacuum tank 11 through the connecting pipe 17, and the valve chamber 1 is normally closed when the pump P is in operation.
A suction valve 24 is provided which opens when the pressure of the odor fed into the deodorizer 9 reaches a certain cracking pressure and sends the odor into the deodorizer 23 via a delivery pipe 22 to be described later.

In this embodiment, check valves are used as these valves 21 and 24.

The delivery pipe 22 rises from the upper part of the valve chamber 19, is bent at a substantially right angle above the suction valve 24, and is piped horizontally. guided into the gap formed between the lower end of the agent and the separator, and further bent approximately vertically downward from the center of the deodorizer,
The tube end opening is positioned directly above the bottom surface of the deodorizer 23.

In this case, it is also possible to fix the end of the delivery pipe 22 to the bottom surface of the deodorizer 23.

Reference numeral 25 denotes a number of spout ports formed on the circumferential surface of the end of the delivery pipe 22 installed in the deodorizer 23, and according to experiments conducted by the applicant, the best deodorizing effect can be obtained with a diameter of 5 mm or less. Ta.

Therefore, the odor emitted from the delivery pipe 22 in the deodorizer travels straight from the pipe end opening of the delivery pipe 22 toward the bottom of the deodorizer 23, and part of the odor is emitted from the spout 25 to the outside of the delivery pipe 22 in the radial direction. It will be released to

The deodorizer 23 consists of an elongated cylinder with a bottom, and a discharge port 26 is formed on the top surface of the deodorizer 23. A deodorizing agent 27 such as activated carbon that absorbs water is housed therein, and a deodorizing cylinder 28 that vertically supports the delivery pipe 22 is fixed to the lower part of this deodorizing agent 27.

As shown in FIGS. 3 and 4, the deodorizing cylinder 28 includes an elongated cylindrical main body 29 whose peripheral wall is located outside an exhaust hole formed in a separator, which will be described later, and an isolator fixed to the upper end of the main body 29. a plate 30, a partition plate 31 which is fixed inside the main body 29 at a substantially mid-high position and has a flange 31a projecting to the outside of the main body 29; and a partition plate 31 which is fixed inside the main body 29 at a position below the partition plate 31. The partition plate 32 is made up of a partition plate 32.

The main body 29 has vents 33 that also serve as drainage ports on the upper, right above, and lower circumferential surfaces of the partition plate 31 and on the entire lower half circumferential surface. The vent hole 33 provided at this position functions as a drain port for deodorized water, which will be described later.

Each of these vent holes 33 is constituted by a small hole, and in the case of the embodiment, is formed to have a diameter of 10 mm.

The separator 30 is formed into a disc body with an insertion hole formed in the center to receive the delivery pipe 22, and the plate surface has a plurality of exhaust holes 34 for discharging the odor inside the main body 29 toward the deodorizer 27.
The outer peripheral end of the separator plate 30 is fixed to the inner wall of the deodorizer 23 to divide the inside of the deodorizer 23 into a deodorizer chamber 35 and a deodorizer chamber 36.

The partition plate 31 is configured as a plate with an insertion hole formed in the center to receive the delivery pipe 22, and partitions the inside of the deodorizing cylinder 28 into an upper inner chamber 37 and a lower inner chamber 38, and also divides the inside of the deodorizing cylinder 28 into an upper inner chamber 37 and a lower inner chamber 38. The deodorizing cylinder chamber 36 is divided into an upper outer chamber 39 and a lower outer chamber 40 through the outwardly projecting collar 31a, and these upper and lower outer chambers 39 and 40 are connected to the collar 31a and the deodorizer inner wall. They communicate with each other through a gap 41 formed between them.

The partition plate 32 has a plurality of vent holes 42 on its plate surface, which allows the odor that is discharged from the delivery pipe 22 and rises inside the deodorizing cylinder 28 to circulate, and also to circulate the odor that is discharged from the delivery pipe 22 and rises inside the deodorizing cylinder 28, and to connect the lower inner chamber with this partition plate 32 as a boundary. 38 into first and second lower interior chambers 43,44.

Reference numeral 45 denotes deodorized water stored in the deodorizer 23, which mainly dissolves hydrogen sulfide components in the odor to deodorize the water. It has been invested.

This deodorized water 45 is filled to a predetermined capacity to ensure a constant deodorizing ability, and an adjustment cock 46 is provided below the outer peripheral surface of the deodorizer 23 to adjust the water level of the deodorized water 45 to ensure this predetermined capacity. A water intake cock 47 is provided above this, and a drain cock 48 is provided below.

Therefore, the lower part of the deodorizing cylinder 28 is always immersed in the deodorized water 45, and the open end of the delivery pipe 22 and the spout 25 disposed inside the deodorizing cylinder 28 are also immersed in the deodorized water.

When using the deodorizing device of the present invention configured in this manner to deodorize odor generated from an odor source such as human waste stored in the vacuum tank 11, the valve change valve 14 is set to the state shown in FIG. Then, the motor M is driven to cause the pump P to perform suction operation, and the odor in the vacuum tank 11 is guided into the switching valve 14 via the connecting pipe 13.

The odor introduced into the switching valve 14 flows out into the connecting pipe 17 via port P1, port P2, guide pipe 15, guide pipe 16, port P3, and port P4, as shown in FIG. It is sent into the communicating valve chamber 19.

When the pressure of the odor sent into the valve chamber 19 reaches a certain pressure, that is, the cracking pressure of the suction valve 24, the suction valve 24 opens, and the odor inside the valve chamber 19 is introduced into the deodorizing cylinder 28 through the delivery pipe 22. It will be destroyed.

In this case, the vacuum tank 11 and the valve chamber 19 are at approximately the same pressure via the connecting pipes 13 and 17, but since these and the deodorizing cylinder 28 are normally shut off by the suction valve 24, for example, the vacuum When the pressure inside the tank 11 increases abnormally, the suction pressure of the pump acts in addition to this abnormal pressure, and the pressure inside the deodorizer 23 increases abnormally, resulting in deodorized water 45.
It is possible to prevent the situation in which the deodorizing agent 27 is violently scattered, deteriorating the deodorizing effect of the deodorizing agent 27, and damaging the inside of the container.

The odor led into the deodorizing cylinder 28 by the exit pipe 22 is ejected outward from the spout 25 formed at the end of the delivery pipe 22, as shown in FIG. These bubbles are ejected from the opening of 22 and released into the deodorized water 45 in the form of fine bubbles.

The odor ejected from the ejection port 25 diffuses outward in the radial direction of the delivery pipe 22 depending on the ejection speed, and when it passes through the vent 33 of the main body 29 surrounding the outside of the delivery pipe 22, air bubbles are shredded and further refined. and floats in the deodorized water 45.

The odor released from the opening of the delivery pipe 22 also follows a similar route, and the bubbles are made fine.

Therefore, the odor discharged from the delivery pipe 22 in the form of bubbles has a relatively expanded surface area in contact with the deodorized water 45 as the bubbles become finer. absorption becomes active, and its deodorizing effect is promoted.

The odor released in the form of bubbles to the outside of the main body 29 floats in the deodorized water 45 and reaches the liquid level of the deodorized water 45, and moves upward in the lower outer chamber 40, while the odor emitted from the main body 29 The bubbles from the odor 1 that have reached the liquid level of the deodorized water 45 inside the chamber then pass through the vent hole 42 formed in the partition plate 32 and flow into the second lower inner chamber 44 or the first lower inner chamber. 43, the partition plate 3
The odor flows out from the vent hole 33 formed directly under the air vent 33 into the lower outer chamber 40 (7) and joins with the odor that took the other route described above.

The odors that merged in the lower outer chamber 40 then flow into the upper outer chamber 39 through the gap 41, and are forcibly circulated in a U-shape at the upper part of the closed upper outer chamber 39, resulting in ventilation 1. 33 into the upper inner chamber 37, flows into the deodorizer chamber 35 through the exhaust hole 34 formed in the separator 30, and after the remaining odor components in the odor are absorbed by the deodorizer 27, exhaust 1126
is emitted into the atmosphere.

In this way, part of the odor released from the delivery pipe 22 is
A path is taken in which the odor flows out from the vent 33 directly under the partition plate 31 into the lower outer chamber 40 and passes through the gap 41 near the inner wall of the deodorizer 23, and after merging, the odor flows into the upper outer chamber 39 in a U-shape. A meandering path is taken in which the air flows into the upper inner chamber 37 from the vent 33.

For this purpose, the space around the deodorizing tube is effectively utilized to create a long path for the odor flow, making it possible to reduce the size and weight of the deodorizer compared to a deodorizer having a straight path.

In addition, as a result of odor being released into the deodorized water 45, the deodorized water 4
The water level of 5 rises accordingly (Figure 2 shows a stationary state), and some of the deodorized water 45 scattered in the deodorizer 23 infiltrates into the upper inner chamber 37, but in this case. In this case, the splashes of deodorized water 45 generated in the lower inner chamber 38 are blocked by the partition plate 31 and prevented from directly entering the upper inner chamber 37, and also flowed out through the vent 33 to the outside. The droplets, together with the droplets generated in the lower outer chamber 40, are blocked by the flange 31a and fall downward.

Furthermore, even if the droplets flow into the upper outer chamber 39 across the gap 41, most of the droplets are blocked by the separator 30 that closes the upper end of the upper outer chamber 39 and the circumferential surface of the deodorizing tube 28, It is prevented from entering the interior chamber 37 or the deodorizer chamber 35, and falls downward through the gap 41.

Even if droplets were to enter the upper interior chamber 37 through the vent 31, since the iron base 37 is substantially sealed, their path would be blocked by the interior wall and would flow out through the vent 33. Secondary generation of droplets within the chamber 37 is prevented.

The droplets that have entered the upper and outer chambers 37 and 39 are immediately drained downward through the gap 41, so the deodorized water 4
5 can efficiently deodorize a large amount of odor without stagnation.

On the other hand, even if some of the droplets that have entered the upper inner chamber 37 try to flow out from the exhaust hole 34 of the separator 30, the positions of the ventilation hole 33 and the exhaust hole 34 formed in the deodorizing cylinder 28 are quite far apart. , such situations will be very rare,
Suppose some droplets flow out from the exhaust hole 34 and enter the deodorizer chamber 35.
Even if the deodorizer 27 enters the inside, the force of the droplets is significantly reduced, and furthermore, since the deodorizer 27 is located apart from the separator 30,
The droplets will not leak the deodorizer 27 and cause it to deteriorate.

Next, when the human waste stored in the vacuum tank 11 is to be discharged to the outside, the switching valve] 4 is switched as shown in FIG. 6 via an operating lever (not shown), and the motor M and pump P are When driven, air sucked in from the suction port 20 is guided into the valve chamber 19 via the discharge valve 21 and into the switching valve 14 via the connecting pipe 17, as shown in FIG.

The air guided into the switching valve 14 is transferred from boat P4 to port P.
2-Guiding tube 15-Guiding tube 16-Port P3-Port P0
The human waste flows out into the connecting pipe 13 through the connecting pipe 13, is forced into the vacuum tank 11 communicating with the connecting pipe 13, and due to the pressure is discharged from the suction pipe 12 to the outside together with odor.

In addition, in the above-mentioned embodiment, the deodorizer's inner and outer chambers are divided vertically into multiple sections, but this is not limited to this example, and it is also possible to divide the deodorizer into multiple sections inside and outside in the radial direction. Although the case where the invention is applied to a deodorizing device for a vacuum car has been described, the invention is not limited to this, and can also be applied to household septic tanks, large-scale sewage treatment plants, etc.

As described above, in the deodorizing device of the present invention, the delivery pipe communicating with the vacuum tank is guided into the deodorizer containing deodorized water in the lower part, the pipe end of the delivery pipe is immersed in the deodorized water, and the delivery pipe is removed from the delivery pipe. In order to deodorize the discharged odor, the flow path for deodorized water or its droplets that mix with the odor flow and flow through the deodorizer is made longer, and the inside of the deodorizer is divided into multiple chambers. Since we have taken measures to prevent droplets from entering the deodorizer, and if any droplets do enter, we have taken all possible precautions to remove them, making it possible to strongly prevent the deodorizer from deteriorating due to water leakage.

That is, in the present invention, the interior of the deodorizer is divided vertically into a deodorizer chamber and a deodorizer cylinder chamber via a separator, the deodorizer chamber accommodates the deodorizer at a distance from the separator, and the deodorizer is placed in this gap. Since the delivery pipe is introduced from the side wall of the pipe, the gap can be effectively utilized and the length of the delivery pipe can be shortened.

In addition, the deodorizing cylinder chamber accommodates a single deodorizing cylinder with a peripheral wall located outside the exhaust hole formed in the separator plate, simplifying the structure and adding a flange at the middle and high position of the deodorizing cylinder. A partition plate was installed to divide the inside and outside of the cylinder into lower and lower parts, so the inside of the cylinder was divided into upper and lower parts. By blocking the ventilation of the side interior chamber, it is possible to prevent the droplets of deodorized water generated in the lower interior chamber from directly infiltrating the upper interior chamber, and the tubes communicate with each other through a gap. In the upper and lower outer chambers, the flanges block the path of the droplets, and the droplets generated in the outer and outer chambers are transferred to the upper outer chamber.
Infiltration can be prevented.

Moreover, on the circumferential surface of the deodorizing cylinder, which is located directly above and directly below the partition plate and spaced apart from the upper separator plate, a ventilation hole [-1] which also serves as drainage is formed to partially drain the interior and exterior of the upper and lower sides. The communication force, together with the gap formed between the flange and the inner circumferential wall of the deodorizer, allows the droplets of deodorized water in the deodorizing cylinder to be quickly drained, thereby improving the deodorizing work. On the other hand, even if droplets enter the upper inner chamber from the upper outer chamber, they can be removed and secondary generation of droplets inside the room can be prevented.

Furthermore, since the vent provided on the circumferential surface of the deodorizing cylinder is located outside the drain hole and is separated from the separator, the droplets that have entered the upper inner chamber do not have the habit of flowing out from the drain hole.
Even if it leaks, the force of the droplets will be significantly reduced, and as mentioned above, the deodorizer is stored away from the separator, so the deodorizer will not leak due to the spilled droplets. This has the effect of strongly preventing deodorization and allowing the deodorizer to be used for a long period of time.

In addition, a number of vents that also serve as drainage ports are provided on the circumference of the lower half of the deodorizing tube that is immersed in the deodorized water, which helps to miniaturize odor bubbles and increase contact with the deodorized water. Together with the prevention of deterioration of the deodorizing agent, the deodorizing efficiency and deodorizing accuracy can be improved.

Furthermore, in the present invention, as a means to meander the odor flow path, a single deodorizing cylinder is provided in the deodorizer 1, partition plates and partition plates are arranged inside and outside of this deodorizing cylinder, and ventilation holes are provided at desired positions of these. Since the structure is formed by forming the structure, the structure is simple and can be easily manufactured.

In addition, the vents formed at the top of the deodorizing cylinder and directly above and below the partition plate also serve as drainage ports, so the level of deodorized water rises during operation of the deodorizer, causing the deodorized water to scatter inside the deodorizer. Even if some of the water enters the upper part of the deodorizing cylinder, it has the advantage of being able to drain through the vent.

Moreover, a separating plate is fixed to the upper end of the deodorizing cylinder to form a partition between the deodorizing agent chamber and the deodorizing cylinder chamber in the deodorizing unit 5. This has the effect of strongly preventing the deodorizing agent from entering the deodorizing chamber, and strongly preventing the deodorizing agent stored in the deodorizing chamber from deteriorating due to wet water.
