Description

  The present invention relates to a liquid agent spraying apparatus, and more particularly to a liquid agent spraying apparatus used for cleaning inside a container, promoting drying, and cleaning a narrow narrow part other than a container.

In general, containers used for maritime transportation and the like are washed with water at any time after the cargo is carried out so that filth and bad odor do not adhere to the cargo to be transported, so that the inside of the container after washing is wet with water. Besides the cleaning action, the inside of the container may get wet with water.
Conventionally, a container whose interior is wet with water by such a cleaning action or the like has been naturally dried by opening the door.
However, when natural drying is performed in this way, a drying period of at least several days is necessary, and therefore there is a problem that the idle period until the container is used again becomes longer and the operation rate of the container is lowered. .

  In order to solve such a problem, various apparatuses for promoting cleaning and / or drying of containers have been proposed so far. For example, a self-propelled cart provided with a nozzle that blows dry air onto a surface wet with water, a carry-in cart that carries the cart into a container, and a high-pressure water supply device (see Patent Document 1) Or a self-propelled container cleaning device (see Patent Document 2) that sucks moisture with a floor surface suction tool provided on the traveling carriage on the surface wet with water, or a hot air sent to the floor provided on the carriage A container drying device (see Patent Document 3) including an air fan and a hot air generator. However, these devices are not practical because they are accompanied by expensive equipment and are extremely large, which makes it difficult to place them at idle and requires maintenance.

On the other hand, various methods are generally used for cleaning oil stains and the like adhering to the narrow part. If the narrow part is a relatively shallow part, a cleaning agent is included in the dust cloth. It is possible to perform operations such as wiping with hands or rinsing with water after spraying the cleaning agent using spray equipment such as hand spray.
However, if the depth is particularly deep in a narrow part, it cannot be wiped and cleaned because it cannot be reached by human hands.While using a long bar-like tool, it can be wiped and cleaned, but workability is poor. Will be forced to work harder and work hours will be longer.
Moreover, when spraying a cleaning agent using a hand spray or a pressure accumulation type sprayer, it cannot be said that it is suitable for a deep part because the spraying distance is short.

In order to solve such a problem, various apparatuses capable of cleaning a narrow part having a deep depth have been proposed so far. For example, an air supply pipe and a liquid supply pipe are attached to the tube tip of an air gun, and a spray device (see Patent Document 4) for spraying a liquid agent with compressed air of an air compressor provided at the tip thereof, and a liquid agent pool tank at a spray nozzle And a high-pressure air cylinder connected to each other, and a liquid agent spraying apparatus (see Patent Document 5) that sprays the liquid agent by bringing the liquid agent pool tank into a pressurized state with high-pressure air from the high-pressure air cylinder.
However, since the former becomes large due to the use of an air compressor, and the latter also becomes large depending on the capacity of the high-pressure air cylinder used, these devices are difficult to place when the periphery of the object to be cleaned is narrow. In some cases, it cannot be used.
Furthermore, since these apparatuses must be manually operated for spraying, the operability is not good in a narrow space, and the operator may be exposed to sewage.

Hereinafter, the present invention will be described in detail.
FIG. 1 is an overall configuration diagram schematically showing an operation flow in the liquid spraying apparatus of the present invention.
In FIG. 1, the liquid spraying apparatus of the present invention includes a liquid spraying apparatus main body installed in or near the spray target and an activation device (D) for starting the gas generator from the remote of the spray target. Composed. The liquid spraying device main body includes a liquid storage tank (A) for storing a liquid, a spray nozzle (B), and a gas generator (C). The spray nozzle (B) is a liquid storage tank (A). Communicated with. The gas generator (C) is also in communication with the liquid agent storage tank (A).

Next, although the Example of the liquid agent spraying apparatus of this invention is described more concretely using FIG.2 and FIG.3, this invention is not limited to this.
2 and 3, reference numeral 1 denotes an activation device, and 2 denotes a liquid spraying device main body. The liquid spraying device main body is composed of 3 gas generators, 10 liquid storage tanks, and 9 or 11 spray nozzles. FIG. 2 shows one embodiment using a fixed spray nozzle 9 and FIG. 3 shows another embodiment using a rotary spray nozzle 11.
Next, details of each component will be specifically described.

  The liquid agent storage tank 10 used in the present invention is not particularly limited as long as the material does not change the liquid agent and can withstand pressurization by the injection gas, and for example, iron, stainless steel, reinforced plastic, or the like is preferable. The size used is preferably determined as appropriate in accordance with the amount of liquid to be sprayed.

The liquid agent sprayed using the liquid agent spraying apparatus of the present invention is, for example, a drying accelerator for accelerating the drying inside the container, a cleaning medium for removing dirt inside the container or a narrow part other than the container, and the like.
The drying accelerator is not particularly limited as long as it has an effect of increasing the evaporation rate of water by an azeotropic phenomenon with water, but is a lower alcohol having 3 or less carbon atoms from the viewpoint of price and availability. In view of the harmfulness, ethyl alcohol is most preferable.
The cleaning medium is not particularly limited as long as it dissolves or removes filth such as oil and off-flavor components, and a commercially available detergent or the like may be used. Further, when cleaning water-soluble filth and the like, water can be used as a cleaning medium.
It is preferable that the amount of the liquid to be sprayed is appropriately determined depending on the volume, size, shape, state, and the like of the spray target according to the purpose of spraying.
For example, when the drying accelerator is sprayed for the purpose of drying the inside of the container, the amount of the drying accelerator used may be determined according to the volume and shape of the container, the wetness, and the like.
Further, when spraying the cleaning medium for the purpose of cleaning the narrow portion, the usage amount of the cleaning medium may be determined according to the area and shape of the object to be cleaned, the degree of contamination, and the like.

In addition, the spray nozzle for discharging the liquid agent used in the present invention is not particularly limited in its aperture, droplet particle size or shape. Also, the position and number of the spray nozzles are not particularly limited, and for example, the type shown in FIG. 2 in which the spray nozzles are fixed in advance so as to spray evenly on the spray object may be used. The type shown in FIG. 3 may be sprayed while rotating the head by the reaction force of water. These conditions are preferably determined appropriately depending on the spray conditions such as the volume, area, shape, spray distance, spray pressure, etc. of the spray object.
In addition, in order to spray as much as possible without leaving a liquid agent in a liquid agent storage tank, you may connect the liquid sending pipe extended to the liquid agent tank bottom surface vicinity to the spray nozzle as needed.

Next, the gas generating means of the gas generator 3 used in the present invention will be described.
It is preferable to use explosives 5 as the gas generating means. This is because the use of explosives can greatly reduce the size of the gas generating means using a motor or an engine and can be constructed at low cost. Also, the use of explosives requires little maintenance. Compared to gas cylinders, explosives can be made more compact, and the gas generator using explosives is also easier to use because it allows the liquid sprayer body 2 to be stationary and the handling of high-pressure hoses is unnecessary. Are better.
Note that the explosives 5 referred to here are combustibles containing explosives, and indicate all those that can generate a jet gas by spraying and spray a liquid agent.

  Although it does not specifically limit as a kind of explosives 5 used here, For example, the substance which has as a main component the nitrate ester represented by the nitrocellulose etc. which are used for automobile safety parts, such as an airbag, A gas generating agent such as a substance composed of a perchlorate represented by ammonium perchlorate or ammonium nitrate or a mixture of a nitrate and a reducing agent represented by amines or azoles can be used. Also, the amount of explosives used is not particularly limited, but if the amount used is too large, the pressure in the liquid agent storage tank will be a problem and the spray device body may be destroyed. If the amount used is too small, the propellant gas The amount is reduced and the desired effect cannot be obtained. Therefore, it is preferable that the amount of explosives used is appropriately determined according to the spraying conditions such as the amount of gas generated per unit weight of the explosives itself, the spray amount of the liquid agent, the required spraying time, the spraying distance, and the spraying pressure. . In order to adjust the spraying conditions, it is also possible to mix an inert substance such as clay or talc with the explosives.

  When the explosives 5 are used as the gas generating means, the generated gas generally has a high temperature. For this reason, when there is a possibility that the effect of the liquid agent is altered and its effect is impaired, or when there is a risk of causing a problem in safety or workability, a cooling means such as the generated gas coolant 7 is provided as necessary. It can also be incorporated. In addition, in the case where there is a possibility that the spraying object may be contaminated due to a large amount of fine particles generated during combustion of explosives, a fine particle removing means such as a filter 6 can be incorporated.

2 and 3 are examples in which the gas generator is accommodated in the liquid agent storage tank, but the gas generator may be disposed outside the liquid agent storage tank. However, the device accommodated in the storage tank can be made compact as a device. In that case, an inflow prevention device such as an open valve 8 is installed at the boundary between the gas generator 3 and the liquid agent storage tank 10 so that the liquid agent does not flow into the gas generator when the liquid agent is injected into the liquid agent spraying device main body 2. Thus, the open valve is opened only when the gas generator burns, and the injected gas can be appropriately flowed into the liquid agent storage tank.
In addition, the spraying device main body can be repeatedly used by making a gas generator into a cartridge type.

Next, the starting means of the starting device 1 for starting the gas generator used in the present invention is not particularly limited, but in general, the gas generator is operated by remotely operating the spray object. It is a device to be activated, and specifically, can ignite the igniter 4 by an electric type or an electronic type to burn explosives.
In addition, when the spray device main body 2 is moved or installed, it is preferable to install a liquid leakage prevention tool so that the liquid agent does not leak out of the spray device main body through the nozzle from the liquid agent storage tank. Specifically, the cover 12 may be removed by the pressure generated when the cover 12 or the like is installed on the spray nozzle and the liquid agent is sprayed.

The spraying conditions such as the spraying time, spraying distance, spraying pressure, etc. of the liquid spraying device of the present invention can be adjusted according to the type and amount of the gas generating agent used. For example, an inert substance may be mixed with explosives. Is possible. Further, in order to adjust the spraying conditions, it is possible to change the installation of a pressure control valve, the diameter of the spray nozzle, and the like.
Moreover, the shape of the liquid agent spraying device main body 2 of the present invention can be arbitrarily designed as long as the liquid agent can be sprayed and the intended effect can be obtained.

Next, the operation of the liquid spray device of the present invention configured as described above will be described.
Ignition accommodated in the gas generator 3 of the liquid spraying device main body 2 installed in or near the spraying object by operating the starting device 1 for starting the gas generator 3 from the remote of the spraying object The explosives 5 are ignited through the tool 4 and burned. Fine particles generated by the combustion of explosives are removed by the filter 6, and the generated gas is cooled as a spray gas through the coolant 7, and then the release valve 8 is opened to flow into the liquid agent storage tank 10. Is pressurized. Along with this, the liquid agent is sprayed from the fixed spray nozzle 9 or the rotary spray nozzle 11 onto the spray object.
For example, when a drying accelerator is used for the liquid agent and the liquid agent spraying device main body is installed inside the container wetted with water and sprayed, the moisture adhering to the container and the drying accelerator are mixed and shared. Since the evaporation rate is higher than that of water alone due to the boiling phenomenon, the drying can be completed in a shorter time than before even after the container door is opened and naturally dried.
In addition, when using a cleaning medium for the liquid agent and installing and spraying the liquid agent spraying device main body in or near the deep narrow part where dirt or the like is attached, it is efficient without requiring manual work for the spraying work. Can be washed.
Furthermore, if a fire extinguisher is used as a liquid agent, it can be used as a fire extinguisher.

As is clear from the above description, the liquid spray device of the present invention does not require a power source such as a motor or an engine, so it is inexpensive, hardly requires maintenance, and is designed to be a compact and stationary spray device. You can also.
When spraying the inside of a container using a drying accelerator as the liquid agent, the drying rate can be shortened, so the operating rate of the container can be increased, and the large and expensive used for purposes such as heat generation, suction, and air blowing. Since no special equipment is required, it is cheaper and smaller than the conventionally proposed devices.
In addition, when using a cleaning medium as a liquid agent and spraying inside a container or in a narrow narrow part other than the container, the cleaning operation can be performed efficiently, so the work time can be shortened and no manual operation is required. The work environment can be improved and the labor of the worker can be significantly reduced. Moreover, since an air compressor and a high-pressure air cylinder are not required, it is smaller in size than a conventionally proposed apparatus, and even if the periphery of the object to be cleaned is narrow, there is no difficulty in placement.
