The woodworking dust collector with the fire-proof function has the technical scheme that the woodworking dust collector comprises a dust collector and a fire-proof device, wherein the fire-proof device consists of a humidification shower nozzle, a solenoid valve, a starting button, a stop button, an intermediate relay, an intermittent relay and a contactor; the humidification shower nozzle is fixedly arranged in a dust cabin below a dust collector filter element by a bracket and is connected with a fire water supply by the solenoid valve; after the normally open contact of the starting button and the normally-closed contact of the stop button are connected in series, the intermediate relay is controlled; the first normally open contact of the intermediate relay is connected with the normally open contact of the starting button in parallel; the second normally open contact of the intermediate relay controls the intermittent relay; the normally open contact of the intermittent relay controls the contactor; and the normally open contact of the contactor controls the solenoid valve. The woodworking dust collector with the fire-proof function has the advantages of simple structure and low cost, fire hazards can be effectively prevented from generating and spreading, and the potential safety hazard of production is eliminated.
Description
Technical field
The utility model relates to a kind of carpenter's dust catcher, and it belongs to the cleaner technical field with generation that effectively prevents the dust catcher interior fires and the function that spreads.
Background technology
Carpenter's dust is a kind of inflammable and explosive dust, in carpenter's dust catcher running, if there is metal (like iron nail) to be inhaled into dust sucting pipeline, and clashes into pipeline, produces spark, just is easy to cause the dust combustion in the dust catcher casing.Existing carpenter's dust catcher does not generally all have special-purpose firebreak device; Owing to be difficult for behind the dust-ignition in the dust catcher casing in time finding, even and find dust combustion, can not smoothly fire water be sprayed onto in the casing; In case thereby the dust in the dust catcher casing catches fire; Be difficult in the best and put out a fire to save life and property and extinguish the blaze in the time, cause greater loss to enterprise, the safety that also can threaten whole factory when serious.
For addressing this problem, the dust sucting pipeline of some advanced carpenter's dust catcher adopts the double-walled cast at present, has the water of certain pressure in the pipe sandwich; Inner-walls of duct is provided with special-purpose Mars sensor, in case metal bump dust sucting pipeline inwall is arranged, produces Mars or spark, and the water in the pipe sandwich can spray this zone, extinguishes Mars.Though this dust catcher can effectively prevent the generation of fire, it costs an arm and a leg, and general enterprise is beyond affordability.
The utility model content
The purpose of the utility model be to overcome prior art deficiency, provide a kind of simple in structure, with low cost and have carpenter's dust catcher of fire-proof function, to eliminate production safety hidden danger.
The alleged problem of the utility model solves through following technical scheme:
A kind of carpenter's dust catcher with fire-proof function; It comprises dust catcher and firebreak device; Said firebreak device is made up of humidifying spraying nozzle, magnetic valve, start button, stop button, auxiliary reclay, intermittent duty relay and contactor; Said humidifying spraying nozzle is fixed in the dust storehouse of filter element for dust collector below through support, and is connected with fire water supply through magnetic valve, control auxiliary reclay after the normally opened contact of said start button and the normally-closed contact of stop button are connected in series; First normally opened contact of auxiliary reclay and the normally opened contact of start button also connect; Second normally opened contact control intermittent duty relay, the normally opened contact control contactor of intermittent duty relay, the normally opened contact control magnetic valve of contactor.
Above-mentioned carpenter's dust catcher with fire-proof function is provided with fire extinguishing sprayer above the filter core of dust catcher, said fire extinguishing sprayer is connected with fire water supply through valve.
Above-mentioned carpenter's dust catcher with fire-proof function, said humidifying spraying nozzle is provided with 4～6, and they are distributed on the same cross section in dust catcher dust storehouse.
Above-mentioned carpenter's dust catcher with fire-proof function; Also comprise warning circuit in the formation; Said warning circuit is made up of temperature sensor, alarm relay and audible-visual annunciator, and said temperature sensor is installed on the sidewall of Body case of cleaner, its normally opened contact control alarm relay; The main normally opened contact guide sound light crossing-signal of alarm relay, the normally opened contact of auxiliary normally opened contact and intermittent duty relay also connects.
Above-mentioned carpenter's dust catcher with fire-proof function, said filter core is cloth-bag type or filter cartridge type.
The utility model has been set up firebreak device on the basis of common carpenter's deduster, this device can intermittently be sprayed water in the dust storehouse in the deduster running, increases the humidity of dust, prevents dust combustion.Warning circuit can send the sound and light alarm signal automatically when dust is on fire, prompting operation person in time opens the fire extinguishing sprayer fire extinguishing, prevents fire spread, also makes humidifying spraying nozzle continue water spray simultaneously, puts out a fire jointly with fire extinguishing sprayer.
The utility model is not only simple in structure, with low cost, and can effectively prevent the generation of fire and spread, and has eliminated production safety hidden danger.
