Description

  The present invention relates to a spraying device and a spraying system for urethane foam used for heat insulation work of buildings such as detached houses and apartments.

As a heat insulating structure of a building such as a detached house, a method of forming a heat insulating layer by spraying urethane foam on the ceiling, attic, walls, under the floor and the like is known.
This urethane spraying work is generally carried out mainly on newly built properties, (i) the spraying area is widened, (ii) the temperature of raw materials needs to be severely controlled, (iii) three layers Due to the need for a power supply of 200V, the spraying device set is large.

  In addition, as a general spraying apparatus, the spraying apparatus of the following patent document 1 is known.

JP-A-10-180153

The conventional spraying apparatus has at least one of the problems described below.
(1) Construction in a narrow area is difficult.
In order to mount a conventional large-scale spraying device set, it is necessary to prepare a vehicle of at least about 2 tons, and in a small area, there is a case where the vehicle cannot be put in and construction cannot be performed.
(2) Problems caused by lengthening of the hose.
As a proposal for solving the problem (1), a method of extending a long hose (currently about 125 m at the longest) from a vehicle equipped with a spraying device to the construction site can be considered, but the preheated spraying material is a hose. Since the temperature drops while passing through, the construction quality tends to be uneven.
Moreover, since the pumping distance of the raw material by a hose becomes long, it will be necessary to enlarge a pump and there exists a possibility that a spraying apparatus may further enlarge.
(3) Problems caused by downsizing.
As a proposal for solving the problem (1), there can be considered a method in which each member constituting the spraying device is miniaturized to such an extent that it can be mounted on a vehicle that can also enter a narrow area.
However, if a reactor, a heater, or the like is replaced with a smaller product, for example, the temperature management performance of the raw material becomes insufficient, and the construction conditions are limited.
In addition, since the miniaturized spraying apparatus inevitably reduces the capacity of the raw material tank, there is a concern that the raw material may be insufficient at a new construction site with a large spraying area.
(4) Problem of power supply.
Each member constituting the conventional spraying device requires a three-phase 200V supply power, and a home power supply (single layer 100V) cannot be used. Therefore, it is necessary to prepare a separate power supply.

  As described above, the present invention aims to provide a spraying device and a spraying system that can solve the problem of volume, the problem of construction quality, and the problem of electric shock supply in a well-balanced manner in order to enable construction in a narrow area. One of them.

1st invention of this application made in order to solve said subject is a spraying device for spraying in-situ foaming urethane, and each pumps up a raw material from the storage part which stores each of a plurality of raw materials, and the storage part, A pump, a heater for heating the raw material, a reactor for controlling a blending ratio of the raw material, a hose connected to the reactor, the hose for heating the raw material flowing into the hose, and the hose A head gun connected to the tip and mixing each raw material, and a compressor for supplying air to the pump and the head gun are provided at least, and the heater, the reactor and the hose are configured to be operable in a single layer 100V. A characteristic spraying device is provided.
According to a second invention of the present application, in the first invention, a generator is further provided for supplying power to at least one of the pump, the heater, the reactor, and the hose.
According to a third aspect of the present invention, in the first aspect or the second aspect, the compressor is driven by an engine.
According to a fourth aspect of the present invention, the spray device according to any one of the first to third aspects of the present invention, and an exhaust device connected to at least one of the compressor and the generator; Is provided in a one-box car, wagon car, van, light van, minivan or mini vehicle.

According to the present invention, at least one of the effects described below can be obtained.
(1) Construction in a narrow area is possible.
By downsizing the spraying device, it can be mounted on a vehicle of less than 2 t trucks, so that it is possible to perform construction in a narrow area that has been difficult to enter in the past.
(2) A reduction in quality can be suppressed.
By providing a heating mechanism in the hose that feeds the raw material, it is possible to compensate for the temperature management performance of the raw material, which is a concern with downsizing of the spraying device. Therefore, unevenness in construction quality can be suppressed as much as possible.
In addition, stable high-quality products can be provided even in low-temperature construction areas.
(3) Construction with a household power supply is possible.
Full-scale urethane foam spraying can be done with just a household power supply.
Also, by preparing a separate generator, construction can be carried out even when power cannot be secured on site or when power is insufficient.
(4) Suitable for renovation construction.
It is more suitable for renovating existing properties that perform spot-like heat insulation than construction in new properties with a large spray area. This is because the capacity of the raw material tank is limited when the spraying device set is reduced in size to be mounted on a vehicle of less than 2 t trucks.
