Definitions
- the invention relates to a signaling and switching device for engine exhaust gas and welding gas conveying systems according to the preamble of claim 1, which is intended in particular for use in workshop areas.
- known engine exhaust gas or welding gas conveying systems with preferably arranged in the ceiling area of a room and having at least one suction blower conveying area and with connected to the latter, variably movable transport means, e.g. a suction hose, said suction blower is used for the entire time of a shift or .Individual longer work phases put into operation, regardless of the current pollutant concentration in the room or area.
- the object of the invention is therefore to provide a signaling and switching device for engine exhaust gas and welding gas conveying systems which does not have the disadvantages mentioned and which can also be produced with little technical and economic outlay and can be retrofitted to said conveyor system which is already in use.
- the object is achieved according to the invention by a signaling and switching device for engine exhaust gas and welding gas conveying systems according to claim 1.
- the subordinate, dependent claims 2 to 10 disclose advantageous developments and variants of the inventive concept.
- the main advantage of the inventive device is that the suction fan (s) of said conveyor system only run when it is absolutely necessary and in an inexpensive construction.
- Fig. 1 is a schematic overall view of a
- FIG. 2 shows a more detailed illustration of the arrangement of the sensor of the signaling and switching device according to the invention and Fig. 3 shows a preferred embodiment of the invention.
- FIG. 1 a workshop room 1 is shown in a highly schematic representation, which is equipped with a motor exhaust gas and welding gas delivery system 3.
- a hanging suction hose or an essentially tubular and swiveling suction arm provided with flexible sections are the source of the gases, the workplaces 2a,... 2n, with the stationary conveyor system located predominantly in the ceiling area of room 1. richly connected 4, the latter 4 having at least one suction fan 5.
- a sensor 9 is arranged in the variably movable means of transport 6, which is connected via its signal line 9c to a control device 10 located outside of said means of transport 6, the latter 10 via a control line 10a is connected to the suction fan (s). Furthermore, it is essential to the invention that the Sensor 9 reacts to carbon monoxide, ammonia, isobutane, alcohol and / or gasoline gases. In a special construction, the sensor 9 has a heating coil 9a and at least one temperature-dependent one that is operatively connected to the latter 9a
- Resistor 9b which is connected to the signal line leading to control unit 10.
- control unit 10 for evaluating the signals supplied by the sensor 9 and for the corresponding control of the suction fan 5 can optionally be set to different limit values for exhaust gases.
- control device 10 can be further configured such that additional optical and / or acoustic signal units can be activated, e.g. to indicate the failure of the suction blower 5 or other defects or dangerous situations.
- the senor 9 is in the rear (upper) region . 7 and / or in the front (lower) area 8 of the variably movable means of transport 6.
- the sensor 9 also functions when parts of the variably movable means of transport 6 are connected larger area run horizontally.
- FIG. 3 shows a special, preferred embodiment variant of the new signaling and switching device for engine exhaust gas and welding gas conveying systems in a schematic view.
- the signal line 9c emanating from the sensor 9 leads here to a transmitter 12, which is fastened in the middle or directly to the suction hose or suction arm 6 and which is matched to a receiver 13 assigned to the control device 10.
- the stationary conveyor system area 4 has a suction slot channel 4a, on which the suction hose or suction arm 6 is interposed
- Hose carriage 14 is slidably supported, the suction slot channel 4a being equipped with busbars 15 facing the hose cart 14 and the transmitter 12, contacting the busbars 15, being arranged in the hose cart 14, and the busbars 15 being connected to the receiver 13 by means of lines 16.
- 24 V AC or 24 V DC can be operated, whereby the The switching signal is transmitted via the busbar 15 by pulse superimposition of the supply voltage, preferably at 24 kHz.
- the inventive concept is used when a said sensor 9 is arranged in an exhaust gas, flue gas or steam conveyor system and the gases or vapors act on the heating coil 9a or the like component in such a way that its 9a temperature changes and as a result of this temperature change Connection to at least one temperature-dependent resistor 9b, control signals are sent to a control device 10, which 10 is at least in operative connection with the (suction) blower 5 of said exhaust gas conveyor system 3.
