FIRE SUPPRESSION SYSTEM FOR RUBBER DUST COLLECTOR

The present invention relates to a fire prevention system for dust collecting apparatuses, and more particularly, to a dust collecting apparatus connected to an grinding apparatus, which is one of remanufacturing tire production facilities, for sucking and discharging dust generated in the grinding apparatus, A fire prevention system for a dust collecting device configured to automatically fire water when the temperature inside the dust collecting pipe of the dust is detected to be higher than a reference value and to clean the inside of the dust collecting pipe if necessary will be.

The remanufactured tire can be made of a tread rubber of original tire or a re-manufactured tread rubber to be recycled, and then the original tire casing can be used after it is worn, thereby promoting the recycling of resources and reducing the economic burden of the consumer Provides advantages.

In order to produce such a reclaimed tire, it is necessary to remove the tread rubber layer originally surrounding the tire body in the circumferential direction of the tire without damaging the main body of the tire. A grinding apparatus is used as a means for removing the tread rubber layer, The apparatus has a structure in which a dust collecting device for collecting dust of the tread rubber layer ground by the grinding apparatus is connected.

That is, the conventional equipment used for producing remanufactured tires includes an abrasive device that is originally rotated at a constant speed to grind the tread rubber layer of the tire, and a grinding device connected to the grinding device for collecting the rubber dusts grinded by the grinding device And a hollow collecting tube connected between the grinding device and the dust collecting device to transfer the rubber dust generated by the grinding device to the dust collecting device.

The dust collecting tube serves as a dust transfer tube configured to have a simple function of sucking and filtering rubber dust generated in the grinding apparatus at a high speed by a dust collecting apparatus. The height and distance of the grinding apparatus and the dust apparatus, And horizontal and vertical tubes in consideration of interference or the like, or a curved tube shape connecting them.

In addition, the dust collecting tube serves to connect a plurality of grinding apparatuses to one dust collecting apparatus. Rubber dust ground in the grinding apparatus passes through the dust collecting tube, and when it is used for a certain period of time, The rubber dust passing through the inside of the dust collecting tube adheres to the inner wall of the dust collecting tube, and the deposition is performed.

In addition, since the inside of the dust collecting tube can not be confirmed, even if rubber dust is accumulated therein, the operator can not easily recognize it, and when rubber dust is deposited inside the dust collecting tube, an overload occurs in the dust collecting apparatus, The efficiency may be lowered and the work environment may be deteriorated. If the spark generated during the grinding operation is sucked into the dust collecting tube, there is a risk of fire.

In other words, originally, the tread of the tire includes not only the rubber material but also a softening agent, a crosslinking agent, etc., and a grinding device rotating at a high speed generates friction with a steel cord originally protruding from the tire main body, The high temperature spark generated at this time is sucked into the dust collecting pipe in which the rubber dust collects, and if it sticks to the rubber dust deposited in the inside thereof and is ignited, it may lead to a large fire.

Therefore, when a fire occurs inside the dust collecting tube and fire occurs, the rubber dust accumulated in the dust collecting tube is connected to the dust collecting apparatus, so that the fire generated in the dust collecting tube can be continued to the dust collecting apparatus, There is a possibility that secondary and tertiary fires will occur to peripheral devices of a tire manufacturing plant, which may lead to not only unexpected economic damages but also loss of life if it leads to a large fire.

However, in the conventional grinding apparatus and dust collecting apparatus for producing re-manufactured tires, there is no apparatus or system for preventing the occurrence of a fire in the dust collecting tube.

Of course, a "dust collector" of Korean Utility Model Registration No. 20-0372901 (registration number: 20-0372901, registered on Apr. 1, 2005.01) can be seen as an example of the prior art, The flame is extinguished through the water film generated by the impeller to prevent fire from coming into contact with the flammable material in the vicinity of the workplace and to clean the dust and dust generated during the work .

However, such conventional dust collectors have a problem in that it is possible to prevent fire from being generated in the dust collector itself, but there is a problem in that it is difficult to positively cope with fires generated in a dust collector connected to the dust collector (device).
