[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for spraying by an antifreezing agent spraying vehicle before supplying the antifreezing agent containing coarse particles or agglomerates having a large particle size to the antifreezing agent spraying vehicle. The present invention relates to an antifreezing agent atomizing apparatus for atomizing particles into particles.

2. Description of the Related Art The freezing of the road surface in winter not only causes serious traffic obstacles but also causes car accidents, and securing safe traffic is an important mission for road managers. Therefore, as a measure for preventing the freezing of the road surface, conventionally, a method of spraying an antifreezing agent such as sodium chloride or calcium chloride on the road surface by a freezing agent spraying vehicle has been generally adopted.

As the antifreezing agent, unprocessed raw salt is naturally cheaper than crushed salt crushed to a particle size suitable for being sprayed on the road surface, but 1 cm is required for the raw salt. ^Since many of them have a particle size of ³ or more, if this raw salt is loaded directly onto a spray vehicle and sprayed on the road surface, the running vehicle will hit the oncoming vehicle by splashing this large particle. May occur. Further, the crushed salt also has a property of being bonded and solidified by absorbing moisture to grow into a large-sized lump. For this reason, conventionally, the large-diameter coarse-grained antifreezing agent or lumped antifreezing agent as described above has been manually shredded with a hammer etc. before being loaded into the spray truck. Since the amount of anti-freezing agent required is several tons, such manual crushing process requires a great deal of labor and time, and road surface anti-freezing work is urgent because there are many late nights during extremely cold weather. Nevertheless, there was a problem that the spraying vehicle could not carry out a quick spraying work on the road surface.

On the other hand, in order to speed up the loading time of the anti-freezing agent on the spray vehicle and to make the arrival of the spray vehicle at the destination as smooth as possible, it is fixed on the main routes such as highways and national roads. A base is set up for each section to store a large number of packs of 1 ton of anti-freezing agent delivered from a supplier at all times, and the anti-freezing agent is loaded into the spray car through a sieve net into the hopper of the spray car. Is being done. That is, a building such as a warehouse storing a pack of 1 ton is placed on the upper and lower floors, and a sieve net is stretched on the upper floor, while the lower floor is used as a standby portion for spraying vehicles and sprayed on the lower floor. After the car entered, the pack was hoisted by a crane and the bottom of the screen was opened above the sieving net to drop the antifreeze agent, and the small-diameter powder antifreeze agent that passed through the sieving net was put into the hopper of the spraying car. is doing.

[0005]

However, since the large-diameter, coarse-grained antifreezing agent that cannot pass through the sieving net remains on the sieving net, the worker must manually pulverize the antifreezing agent and put it into the spray car. However, there is a problem that the work requires a great deal of work. Further, as described above, the work of loading the antifreezing agent on the spraying car is required to be quick, and this request is not a problem if the loading of 6 packs for one spraying car is within 15 minutes, In the above-mentioned sieving network, it often happens that it takes longer time.

When a crusher is used in place of such a sieving net, the time required for atomizing 1 ton of antifreezing agent is required to be about 2 minutes, which satisfies this requirement. Requires a large crusher, which poses a problem in terms of installation space, power source, and cost.

On the other hand, the applicant of the present application has developed an antifreezing agent spraying vehicle in which a crushing agent for antifreezing agent is attached to a spraying vehicle and the antifreezing agent is crushed by the crushing machine immediately before spraying. If foreign matter is mixed into the crusher, there is a risk that it will not be possible to spray, and it will be extremely expensive to install such a crusher on all the spray cars assigned to the base. Become.

The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to reliably and efficiently atomize an antifreezing agent and to atomize a predetermined amount into a spray vehicle.

It is configured to adjust the amount of the antifreezing agent fed into the crusher from the side through the discharge port to the amount of the granulation processing by the crusher.

[0013]

[Operation] When an antifreezing agent containing a large-diameter coarse-grained or agglomerate antifreezing agent is put on the inclined vibrating screen, the antifreezing agent having a fine particle size suitable for spraying is sieved downward by the inclined vibrating screen. On the other hand, the antifreezing agent, which is coarser than the sieve mesh, falls into the crusher from the discharge port on the lower sloping end side of this oscillating sieve due to the vibration of the inclined sieving sieve, and the crusher freezes the fine particle size suitable for spray After being crushed by the inhibitor, it falls downward from the lower end of the opening of this crusher.

The anti-freezing agent is applied to the spray vehicle A in the shortest possible time.

For example, when the antifreezing agent F is a raw salt which is easy to cost, the raw salt having a particle size of 5 or 6 mm or less suitable for being sprayed on the road surface is about 70% and is not suitable for spraying 5,6 mm. About 30% of the above particle size is included. Therefore, 50% of the total amount of raw salt is sieved off by the inclined vibrating screen 1, while the remaining 20% of the particle size is less than 5 or 6 mm. The magnitude of vibration of the sieving net 12 is adjusted so that the raw salt and the raw salt having a particle size of 5 or 6 mm or more present in a ratio of 30% with respect to the total amount of the raw salt are processed by the crusher 2 side. In addition, if the opening area of the discharge port 5 fed into the crusher 2 from above the sieving net 12 is adjusted by the opening of the door, the slanting vibration sieving 1 and the sieving process capacity of the crusher 2 are about 50.
