DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device for preventing odors from scattering outside a garbage truck when collecting garbage.

[0002]

2. Description of the Related Art Generally, in a garbage collection vehicle, collected garbage packed in a bag is thrown into a collection port, and is pressed into a collection room by operating a press plate. In some cases, the liquid may leak and the odor may be scattered to the outside. This may cause discomfort to the surrounding residents and impair the working environment of the workers. As a countermeasure against foul odors from waste transport vehicles such as manure and garbage, there is a proposal (Japanese Unexamined Patent Publication No. Hei 6-73779) in which foul odors are sent to the internal combustion engine of a car through piping to burn and incinerate them. It is difficult to collect odors emitted from the mouth in a limited place, and there is currently no measure at all.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. The deodorizer here is
For example, as shown in FIG. 1 and FIG.
A deodorizing liquid tank 2, a plunger type reciprocating pump 3 for transport, a pipe 4, and a pipe 4 located at an upper portion of the collection port 1a are provided at a terminal of the pipe 4 in a so-called town back 2 ton truck. It is equipped with three spray nozzles 5.

In this embodiment, the deodorant liquid tank 2 is
In consideration of the convenience of replenishment of the deodorant, it is provided on the vehicle-mounted bracket 1b provided on the side of the vehicle body, and three transport pumps 3 are mounted alongside it. The pipe 4 extends from the rear of the driver's seat 1c to the upper part of the collection port 1a at the rear of the vehicle body.

Further, the above-mentioned deodorizing device is provided with a collected material inlet 1.
a control means for driving the transport pump 3 in the process of raising the press plate 6 for pushing the collected material into the collection chamber 1d from a (in this embodiment, shown as a relay box for electrical control) 9 And switch means 8 for controlling the control means 9 in the process of raising the press plate 6.

In this embodiment, the above-mentioned switch means 8 employs a limit switch structure which is interlocked with the operation of the hydraulic actuator 7 of the press plate 6.

The deodorant is stored in the deodorant tank 2 and is sprayed from the spray nozzle 5 into the garbage collection port 1a.
The deodorant liquid can achieve this purpose as long as it has a deodorizing function, but a preferred form of the deodorant liquid is a liquid containing metal phthalocyanines.

The metal phthalocyanines are represented by the above formula (2). The substituents R ^{1 to} R ⁴ in the formula are each independently
It is selected from hydrogen, an alkyl group, a substituted alkyl group, a halogen group, a nitro group, an amino group, a carboxylic acid group, a carboxylamide group, a nitrile group, a hydroxyl group, an alkoxyl group, a phenoxyl group, a sulfonic acid group, and a sulfonamide group.
Among them, hydrogen, carboxylic acid group, sulfonic acid group and hydroxyl group are preferably selected.

In the formula, M is Fe, Co, Mn, T
A metal selected from i, V, Ni, Cu, Zn, Mo, and W, of which Fe and Co are preferably selected.

Preferred examples of the metal phthalocyanines include phthalocyanine carboxylic acid, phthalocyanine sulfonic acid,
More specifically, it is a complex of any of iron (Fe) and cobalt (Co) such as phthalocyanine tetracarboxylic acid, phthalocyanine octacarboxylic acid, phthalocyanine monosulfonic acid, and phthalocyanine tetrasulfonic acid.
Since the method for producing metal phthalocyanines is already known in this field, detailed description is omitted, but by way of example, iron phthalocyanine tetracarboxylic acid is trimellitic anhydride, urea, ammonium molybdate, Ferric chloride anhydride and nitrobenzene
The precipitate is obtained by heating and refluxing with stirring to obtain a precipitate. The precipitate is hydrolyzed by adding an alkali, and then acidified by adding an acid (see, for example, JP-A-5-58897).

The solution containing the metal phthalocyanines is preferably an aqueous solution, and the concentration of the metal phthalocyanines is not limited, and may be determined in consideration of the amount of spray, but is usually 0.05 to 5% by weight, preferably 0 to 5% by weight. 0.1 to 1% by weight.

It is preferable to further add high molecular weight amines, preferably cationized amines, to the solution containing metal phthalocyanines. Examples of amines or cationized amines include polyallylamine, polyamines from dimethylamine and epichlorohydrin,
And compounds containing benzalkonium chloride. Although the amount of addition varies depending on the compound, the preferred compounding ratio is 0.05 to 1 times (weight) with respect to the metal phthalocyanines. These compounds can enhance the deodorizing action of metal phthalocyanines, suppress the growth of microorganisms in the system as an antibacterial agent, and prevent the slime-like substances from obstructing the tube.

Further, when any of the deodorants is used,
Rust inhibitors and other additives may be added to the deodorant liquid,
The present invention does not hinder these additions as long as the deodorizing action is not impaired.

The deodorizing apparatus according to the present invention is configured as described above. When the collected material inlet 1a is opened and the garbage collected is charged, the press plate 6 is raised for scraping. Then, the limit switch (switch means 8) is intermittently turned on, and the control means 9 is turned on. Thereby, the transport pump 3 is driven, for example, by one reciprocation, and the deodorizing liquid is supplied from the deodorizing liquid tank 2 to the spray nozzle 5 through the pipe 4, and the opening width of the collection inlet 1a is reduced. It is sprayed intermittently while forming a mist-like film to cover.

The spray amount of the deodorant at this time depends on the type and concentration of the deodorant, but for example, the total amount of the three spray nozzles 5 per one reciprocating operation (one cycle) of the press plate. , 0.5 to 3 cc.

In this embodiment, a transport pump is prepared for each spray nozzle.
The piping may be shared, and the deodorant liquid may be supplied to each spray nozzle.

[0024]

As described above, according to the present invention, the deodorizing liquid tank, the transport pump, the pipe, and the spray nozzle provided at the end of the pipe located above the collection port of the garbage truck. And control means for driving the transport pump in the process of raising the press plate for pushing the collected material into the collection chamber from the collected material input port, and turning on the control means in the process of raising the press plate. Equipped with switch means to control. Therefore, at least,
At the collection port, it is possible to eliminate the bad odor from the inside of the collection chamber to the outside and to preserve the sanitary environment.
