Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating device, and an object of the present invention is to provide a device that can efficiently mix heat insulating particles and adhesive used for insulation work in attic spaces, etc. be.

In recent years, instead of polystyrene foam boards, glass wool, etc. used for insulation construction of houses and other buildings, insulation construction methods have been developed in which insulation particles are directly injected into ceilings, walls, etc.

During the above construction, in order to prevent the outflow and movement of the heat insulating particles and maintain the shape, a method is used in which a mixture of heat insulating particles and adhesive is injected into the construction site.
There has been a need for a foundation layer that can uniformly mix such heat insulating particles and adhesive and has excellent work efficiency. Therefore, the present invention satisfies the above-mentioned needs and provides a device that can efficiently and automatically mix the heat insulating particles and the adhesive.The device is composed of a combination unit that pumps the heat insulating particles together with compressed air. Lesser or blower;
an adhesive supply pump that supplies a fixed amount of adhesive into a pressure pipe connected to the compressor or blower, the pressure pipe being introduced from the circumferential direction into a cyclone hopper made of a funnel-shaped cylinder, - An exhaust port is provided at the top, and an outlet for the heat insulating particles mixed with the foundation frame is provided at the bottom of the cyclone hopper, and a screen is provided at the bottom of the cyclone hopper, and the bottom of the screen is used to collect excess adhesive. It is characterized by being made with a department.

Next, embodiments of the present invention will be illustrated below with reference to the drawings. 1. It is a delivery mechanism such as a compressor or a blower that pumps the heat-insulating particles A together with compressed air, and a suction pipe 1 is provided on the suction side of the compressor 10, etc.
A suction nozzle 12 is attached through the hole 1, and the suction nozzle 12 is inserted into a storage section 13 for the heat-insulating particles A to suck up the particles A.

In particular, if a movable hose is used as the suction pipe 11, it will be easy to operate and have good workability, such as when inserting the direct suction nozzle 12 into the bag to suck up the insulating particles A packed in the bag. Become. A pressure pipe 14 is connected to the discharge side of the compressor 10, etc.
From there, the heat-insulating particles A are pumped together with compressed air to a cyclone hopper, which will be described later.

Reference numeral 20 denotes an adhesive tank, and a supply pump 21 sucks up adhesive from the tank 20, and supplies the adhesive to the pressure feed pipe 14 through an adhesive supply pipe 22 connected to the middle of the pressure feed pipe 14.

The supply pump 21 is capable of adjusting the amount of adhesive supplied, and can always supply a fixed proportion of adhesive to the heat insulating particles A that are pumped through the pressure pipe 14. The adhesive supply pump 22 is connected diagonally to the pressure pipe 14 so that adhesive can be smoothly fed into the pressure pipe 14. In addition, it is preferable to supply the adhesive in such a way that it is vigorously sprayed onto the heat-insulating particles A being fed through the pressure-feeding pipe 14, as this will improve the mixing of the heat-insulating particles A and the adhesive. If the agent is sprayed in atomized form, use compressor 1 for pressure feeding.
The adhesive is sprayed without being atomized because it interferes with the suction force of 0, etc., and the atomized adhesive is discharged from the exhaust port of the cyclone hopper, which will be described later, and is wasted, which is not desirable in terms of environmental hygiene. Next, 30 is Cyclone Hopper,
The entire body is formed into a substantially funnel-shaped cylindrical body, and a pressure pipe 14 is introduced into the upper part from the circumferential direction.

Reference numeral 31 denotes a wire mesh, which covers the opening □ on the top surface of the cyclone hopper and discharges compressed air using the wire mesh 31 as an exhaust port. At this time, the heat-insulating particles A are blocked by the wire mesh 31 and do not dissipate to the outside. It becomes suitable.

Note that it is also possible to implement the same structure as a conventional cyclone in which the upper surface of the cyclone hopper 30 is closed and a pipe-shaped exhaust port is inserted into the center of the cylinder (not shown). A screen 32 is provided on the bottom surface of the hopper 30, and excess adhesive that has not adhered to the heat insulating particles A is removed from the screen 32.
into the reservoir 33 provided at the bottom of the. Reference numeral 34 denotes an outlet, which takes out the heat insulating particles A mixed with the adhesive.
The heat insulating particles A can be directly injected and filled into the construction site through an injection nozzle 41 attached to the construction site.

Note that the heat-insulating particles A and the adhesive taken out from the outlet 34 are not sent directly to the injection nozzle 41, but are collected into another tank, etc., and then filled with a separate injection blower and injection nozzle. It is also possible to inject and fill the particle A into a construction site, such as an attic, where it is intended to be used. Next, 35 is a drain port, and the drain port 3
5 is used not only for draining, but also as a drain port 35.
When the cyclone hopper 30 starts operating, the heat-insulating particles A remaining in the hopper 30 are blown up from below by the fly-azusa blower 36 and turned into adhesive again. If the mixture is sufficiently mixed, the remaining heat-insulating particles A can be used effectively and without waste, making it suitable.

The heat-insulating particles A used in the above device include foamed synthetic resin particles such as polystyrene, polyethylene, and polypropylene, copolymer resins or mixed resins of these resins, and inorganic foamed particles such as perlite and vermiculite. can also be mentioned, and the size of these insulating particles is 1 to 1
Particles with a particle size of about 500 ml can be used as appropriate.

In addition, as adhesives, 1,2-polybutadiene obtained by living polymerization of butadiene, drying oils such as linseed oil, linseed oil, soybean oil, and tung oil, latex, vinyl acetate, etc. are used. If the amount used is too small, the adhesive for the heat insulating particles will not be sufficient, while if it is too large, the fluidity of the heat insulating particles will be affected, which may cause the adhesive to come out during construction, which is undesirable. It is desirable to select and use it appropriately within a range that does not cause such damage. Furthermore, cobalt naphthenate, lead naphthenate, or the like may be added to the adhesive in order to accelerate its curing. In the above-mentioned shelf clothing layer, for example, polystyrene foam particles are used as the heat insulating particles, drying oil is used as the adhesive, and the air flow rate of the compressor 10 is set to 20 to 40 /
sec, the pumping flow rate of particles from the compressor 10 is 40~
100 m/min, the pumping speed of the heat insulating particles in the pumping pipe 14 is 0.6 to 2.0/sec, the pumping speed of the adhesive is 40 to 80 cc/min, and the air suction speed at the outlet 34 is 30 to 2.0/sec. 50 m/sec, the particle suction speed at the outlet 34 was 0.6 to 2.0 m/sec, and the size of the cyclone hopper 30 was 400 x 45 mm. As a result, the mixed state of the heat insulating particles and adhesive was It was possible to inject and fill the construction site with a uniform and good quality material at a rate of 5 to 7 times per hour, and work efficiency was significantly improved compared to conventional methods.

According to the invention configured as described above, the heat insulating particles are sent together with compressed air by the compressor or blower into the cyclone hopper through the pressure pipe, and the adhesive is supplied into the pressure pipe by the adhesive supply pump. The heat insulating particles and adhesive are then sprayed and mixed with the heat insulating particles, and then the heat insulating particles and the adhesive are fed into the hopper along with compressed air through a transport pipe introduced from the circumferential direction into a cyclone hopper consisting of a funnel-shaped cylinder, and the inner wall of the hopper is Move it downward while rotating along the . At this time, the heat insulating particles and adhesive collide with each other and rub against the inner wall of the hopper, so that the adhesive adheres to the entire surface around the heat insulating particles, which is much more uniform and better than in conventional crossing tanks. A mixed state can be obtained. Moreover, if the heat-insulating particles and adhesive are supplied, the mixed heat-insulating particles can be taken out continuously from the outlet at the bottom of the hopper, eliminating the trouble of having to use a retaining pestle every fixed amount as in the past. By connecting a blower for injecting insulation material directly to the take-out port, it becomes possible to seamlessly perform the process from supplying raw materials to filling work, which improves work efficiency and improves insulation material injection after competitive punching. Since there is no need for a tank to store water, it also helps to downsize the entire equipment. Furthermore, since the amount of adhesive supplied can be adjusted using the supply pump, a fixed ratio of adhesive can always be supplied to the heat insulating particles, and the optimum mixing ratio can be selected depending on the construction conditions and the like. Furthermore, if the heat insulating particles and adhesive are allowed to stay in the cyclone hopper for a long time, the adhesive will settle to the bottom, resulting in excessive adhesive adhering to the heat insulating particles below. The device is equipped with a screen at the bottom of the cyclone hopper, and excess adhesive falls into the pool at the bottom of the screen, so that only the appropriate amount of adhesive always adheres to the insulating particles, and the adhesive is released from the outlet at the bottom of the hopper. It is also convenient to take it out.

Therefore, in the suction filling construction of insulation materials, the process from supplying the heat insulating particles and adhesive to mixing the cypress using a cyclone hopper is continuously automated, and the mixing condition is also good. equipment can be provided.
