Description

  The present invention relates to a method and apparatus for controlling pests such as septic tanks.

The removal or prevention of harmful insects such as flies and mosquitoes generated in the septic tank is a difficult problem for users and managers.
As a method and apparatus for exterminating pests in a septic tank, a carrier impregnated or adhered with an insecticidal compound that continues to evaporate at room temperature is disposed in a space in the septic tank and is exterminated over a long period of time. (Patent Documents 1 and 2).

  In addition, as a conventional insecticidal method and apparatus, an insecticide is configured and installed in a container according to the shape, performance, action, etc. of the insecticide, and if necessary, these insecticide components are evaporated, volatilized and evaporated by a heater. Various proposals have been made for forcibly diffusing the light by a fan (Patent Documents 3, 4, 5, 6, 7, and 8).

Japanese Patent Laid-Open No. 9-12405 JP 2006-225408 A JP 58-4533 A Japanese Utility Model Publication No. 49-26141 Japanese Utility Model Publication No. 52-166107 No. 1-335671 Japanese Utility Model Publication No. 62-6211 JP-A-6-153752

  However, it is understood that it is difficult to obtain an effect as expected to dispose of a pest control agent composed of an insecticidal compound in the septic tank in the space and control it for a long time by volatilization of the insecticidal component. I'm crazy.

  The pest control agent is formed by adhering and impregnating a pest-like carrier made of paper, plastic, etc., and suspending the carrier in the septic tank. During the initial period of action, pest control has been carried out due to the insecticidal effect, but the waste water accumulated in the septic tank over time, the water that evaporates due to sewage, etc., entering dust, dust, etc. adhere to the carrier, Prevents the volatilization of medicinal ingredients and reduces extermination ability.

  Furthermore, for example, in a merged tank, a lot of bubbles such as detergents may be generated, and the space in the tank may be filled with bubbles. In such a case, a pest control carrier is also encased, and air circulation is also suppressed. After that, the dirt is remarkably adhered and the deterioration of the pest control ability is accelerated.

In addition, scattered air, sludge, and the like may adhere to the carrier due to air released from the aeration mechanism provided at the bottom of the water purification tank.
When the occurrence of pests increases, there are many cases where the ability decreases and some drugs adhere to the medicine itself, and it is often difficult to achieve the insecticidal effect for the planned period, for example, three months.
Of course, there is no problem if the maintenance and inspection of the insecticide composed of insecticidal compounds is frequently performed, but maintenance and inspection is generally a work to be avoided, and it is left to the contractor. There is almost no cost problem, and it is difficult to carry out at all times, and it is often replaced after the ability of the pest control agent is reduced.

  Therefore, in the present invention, by avoiding the direct work to the septic tank that hangs the pest control carrier directly in the septic tank, anyone can easily carry out the carrier replacement work, and thereby the efficacy of the pest control agent is improved. We propose a method and a device that can be fully exerted at all times to surely control pests.

  In addition, a method and an apparatus for providing a pest control effect by providing a sufficient effect of the pest control agent in the septic tank with a constant air flow without specifying an installation place suspended in the septic tank are proposed.

  In order to achieve these objects, the present invention accommodates or installs an insecticidal compound that volatilizes at room temperature in a sealed container whose lid is openable and closable, and sends air containing the insecticidal compound that volatilizes in the sealed container. A pest control method for a septic tank or the like, which is inserted into a septic tank or the like with a trachea and spreads over a desired portion such as a space.

  In addition, a sealed container having a lid that can be freely opened and closed is provided with a storage or installation portion for an insecticidal compound that volatilizes at room temperature, and a blower is connected to the sealed container, and the insecticidal compound that volatilizes in the sealed container It is a pest control apparatus such as a septic tank, characterized in that it can be fed into the septic tank by an air pipe connected to a discharge pipe or the like.

According to the present invention, the septic tank is not directly touched and does not pass through the septic tank, and the insecticidal compound is housed and contained in a sealed container. Anyone can easily and easily feel unclean. The insecticidal compound can be attached to and detached from the container hygienically without feeling.
For this reason, it is easy to install and replace new insecticidal housing hot water frequently, and air of insecticidal compounds with a large insecticidal effect can always be sent to the septic tank, etc., to ensure the control and prevention of pests. I can do it.

The present invention will be described in detail with reference to an embodiment of the present invention shown in FIG.
Although 1 is a septic tank and shows a general separation aeration septic tank, it is natural that various septic tanks can be used without being limited thereto.

Further, the present invention is not limited to the septic tank 1 and can be used if there is an air discharge inlet in a certain closed space.
For example, the use range such as a water tank, a sewage tank, a sewage tank is wide.
The septic tank 1 is divided into the respective chambers 3, 3, 3 by the partition walls 2, 2, and is provided along the partition walls 2, 2. Has been.

A partition plate 41 is provided corresponding to the side wall 11 of the septic tank 1 outlet 7 to form a passage 61. An inlet 8 is formed in the side wall 12 opposite to the outlet 7 and is connected to a discharge pipe 13.
Reference numerals 9, 9, and 9 are openings provided in the upper part of the septic tank 1, and the lids 10, 10, and 10 are provided to be openable and closable so as to seal the septic tank 1.

The drain pipe 13 is connected to a miscellaneous drainage pipe 15 and a sewage drain pipe 16 via a trap 14, respectively.
20 is a sealed container and is preferably a light pressure-resistant box type. The symmetrical side walls 21 and 22 are provided with an inlet 23 and an outlet 24, respectively. The inlet 23 is connected to a blower 26 via a float 25. It is. The outlet 24 is connected to the discharge pipe 13 by an air supply pipe 201.

  Reference numeral 27 denotes a hermetic lid, which can be freely opened and closed so as to have light pressure resistance. The sealed container 20 is provided with a frame 29 on the upper side thereof, or directly provided on the sealed lid 27 with locking portions 29, 29. is there. As the latching portion 29, various other types such as a bag for storing the carrier, a net bag, a container such as an open container, or an installation member can be used.

  As a pest control agent, a compound such as dichlorovos, a pyrethroid compound, a fluorobenzyl ester compound, dimethyl dichlorovinyl phosphate, or the like is impregnated with an insecticidal compound such as plastic or paper on a plate or a sheet-like carrier 28 and formed. Is used.

An appropriate number of the carriers 28 are accommodated in the sealed container 20. Although it depends on the pest control agent, it is generally considered that a carrier amount of about 500 to 10000 cm ² per 1 m ³ of the space in the septic tank 1 is preferable.

  The sealing container 20 is provided with a diffusion plate 30 having through holes 301, 301... Corresponding to the inlet 23, diffuses the air sent from the inlet 23, and softly hits the carriers 28, 28. The insecticidal compound that volatilizes from the carrier 28 is blown and sent out from the outlet 24.

  Air is sent to the inlet 23 from the blower 26 via the air adjustment valve 33 and the float 25. A silencer box 32 is connected to the blower 26 via an air relief valve 31.

34 is a blower which sends air to the septic tank 1 through the air diffusing pipe 35 to promote the activity of aerobic bacteria and promote the decomposition of waste water and sewage.
Of course, when anaerobic bacteria are used, it is better not to send air into the tank or chamber, and it is of course possible to cut off the air with an air feed prevention mechanism or the like. .

Next, the insecticidal method of the present invention will be described.
The sealed container 27 of the sealed container 20 is opened, and the carriers 28, 28... Are hooked and stored in the locking portions 29, 29. The sealing lid 27 is closed and the operation is started.
First, the blower 26 is operated, the air relief valve 31 is closed, the air adjustment valve 33 is opened, and air is fed into the sealed container 20 through the float 25.

At that time, the air hits the diffusion plate 30 to weaken the force, passes through the through holes 301 and 301, and diffuses into the sealed container 20.
Then, the insecticidal compound that evaporates is wrapped in the air by the carriers 28, 28..., Is sent out from the outlet 24, passes through the exhaust pipe 201, passes through the discharge pipe 14, and is sent into the septic tank 1. In the septic tank 1, waste water and sewage stored in the lids 3, 3... At the upper part of the septic tank 1 are decomposed and purified by aerobic bacteria, and are sequentially discharged from the discharge port 7. At this time, air is always sent to the septic tank 1 from the blower 40 through the septic tank air diffuser 41 and the waste water and sewage are continuously aerated.

In the conventional septic tank, this air contacts over the surface of the drainage and sewage and spreads to the respective chambers 3, 3..., But flows as it is from the discharge port 7, and above the septic tank 1, especially the lids 10, 10. There is little air flowing in the vicinity.
In the case of the present invention, air containing an insecticidal compound is sent out from the discharge pipe 13 and travels in the space between the drainage, sewage and the septic tank 1, particularly in the vicinity of the lid 10. It goes down on the drainage and sewage inside, but the space above the drainage and sewage is filled with an insecticidal compound, fills the vicinity of the lids 10, 10... Above the septic tank 1, and is discharged from the discharge port 7.

  For this reason, pests are easily generated and have a raw odor, and the space 101 of the septic tank 1 is filled with the insecticidal compound, and the state is maintained, and the pest habitat is extinguished.

A second embodiment shown in FIG. 2 will be described.
The basic type is the same as that in FIG. 1, but in this embodiment, the operation of sending air to the septic tank aeration pipe 35 and the operation of sending air to the sealed container 20 are common in the embodiment implemented in the small-scale septic tank. This method and apparatus is performed only by the blower 34. In this apparatus, a diaphragm type is usually used as a pump.

That is, the air from the blower 26 is sent from the septic tank air diffusion pipe 35 and the air diffusion pipe 35 to the branch pipe 351 reaching the sealed container 20 via the branch air adjusting valve 352.
As a result, aeration air is sent to the septic tank 1 from the air diffusion pipe 35, and at the same time, air containing an insecticidal compound is sent to the exhaust pipe 13 or the inlet 8.
In this case, the outlet of the air supply pipe 201 is inserted into the discharge pipe 13, but can be set to any of the inlets 8 of the septic tank 1.

Next, the embodiment shown in FIG. 3 will be described.
In this embodiment, the hermetically sealed container 20 contains a liquid insecticidal solution, which is a liquid insecticidal compound, and is foamed from the liquid by air sent through the float 25 to promote the volatilization of the liquid and float. By sending air containing volatile compounds from the outlet 24 and continuing to dissipate air containing volatile compounds to the septic tank 1 through the air supply pipe 201, the habitat of the pests is eliminated and the pest control effect is obtained. I can do it.
Of course, the pest control solution, which is an insecticidal compound, can be used in either the first embodiment or the second embodiment.
