Abstract
The utility model discloses a dust laying device with the function of automatically spraying water at the outlets of material discharging pipes, and the dust laying device comprises a conveying belt. The utility model is characterized in that a sensor swinging plate is arranged at a material discharging port on the conveying belt; the upper end of the sensor swinging plate is provided with a swinging arm which is connected with a bearing chamber; an approach plate is welded on one side of the swinging arm; an approach switch is installed on a sensor frame; a thread bag on an electromagnetic valve, and the approach switch are connected in series on a circuit; a steel frame is welded between the sensor frame and a belt frame for connection. When coal exists on the conveying belt, the coal pushes the sensor swinging plate, the swinging plate drives the approach plate to swing, and when approaching the approach plate, the approach switch is switched on. As a result, the electromagnetic valve is opened, and a water spraying head sprays water.
Description
The utility model relates to a kind of device of the serious material blanking tube exit automatic water jetting depositing dust of airborne dusts such as power plant, colliery.
Present power plant, when coal came out to fall on the load-transfer device from the hopper mouth, depositing dust was that its shortcoming is with the artificial water spray of opening: during no coal, water is also spraying always, both wastes water like this, also inconvenience on the load-transfer device.
The utility model is at above-mentioned shortcoming, proposes a kind ofly without manual operation, and it is the automatic water jetting depositing dust that coal is arranged on the load-transfer device, stops the material blanking tube exit automatic water jetting device for reducing dust of spraying water during no coal automatically.
Task of the present utility model is finished like this, it comprises load-transfer device, it is characterized in that: be that sensor pendulum plate is installed in the discharging opening place above the load-transfer device, sensor pendulum plate upper end is that swing arm is connected with bearing chamber, is welded with near plate on a side of swing arm, near switch and be installed in parallel on the sensor frame near plate, weld with steelframe between sensor frame and the belt holder, line bag on the electromagnetic valve be connected on the circuit near switch series, solenoid control sprinkler head, sprinkler head are installed in the discharging opening place.When on the load-transfer device coal being arranged.Coal is with belt movement, promote sensor pendulum plate, pendulum strip movable pendulum arm with near the plate swing, near plate with near switch near the time, near switch ways, at this moment electromagnetic valve is opened, and the sprinkler head water spray is on the load-transfer device during no coal, sensor pendulum sheet reset is from hanging down, open circuit near switch, closed electromagnetic valve, the shower nozzle water spray stops.In order to regulate the distance between pendulum plate and the load-transfer device, the positioning bolt is arranged at sensor pendulum plate and swing arm middle device.
The utlity model has following effect: during no coal, the shower nozzle water spray stops, switch ways when coal is arranged, sprinkler head water spray on the load-transfer device.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be of the present utility model near plate with near the A-A scheme drawing of switch;
Fig. 3 is an electromagnetic valve of the present utility model.Near switch.The scheme drawing of shower nozzle water spray;
To describe embodiment in detail in conjunction with above accompanying drawing.Referring to Fig. 1, above the sensor pendulum plate 2 is that swing arm 4 is connected with bearing chamber 7 with bearing 6, it in the middle of sensor pendulum plate 2 and the swing arm 4 positioning bolt 3, on the positioning bolt 3 two positioning holes are arranged, regulate the distance between pendulum plate 2 and the load-transfer device, can regulate distance between sensors pendulum plate 2 and the load-transfer device 1 by two positioning holes of positioning on the bolt 3, be welded in the swing arm 4 near plate 5, near plate 5 with near switch 8 parallel installations, be contained on the sensor frame 9 near switch 8, sensor frame 9 and the welding of belt holder 10 usefulness steelframes, the line bag on the electromagnetic valve 11 be serially connected on the circuit near switch 8.Referring to Fig. 2, Fig. 3, electromagnetic valve 11 control sprinkler heads 12 water sprays, sprinkler head 12 is installed in the discharging opening place, when coal when discharging opening falls into load-transfer device 1, coal is with belt movement, promote sensor pendulum plate 2, pendulum plate 2 drive swing arms 4 with near plate 5 swings, near plate 5 with near switch 8 when parallel, near switch 8 paths, electromagnetic valve 11 is opened, and sprinkler head 12 water sprays are when on the load-transfer device 1 during no coal, sensor pendulum plate 2 resets from hanging down, near plate 5 with open circuit near switch 8, electromagnetic valve 11 is closed, sprinkler head 12 is no longer sprayed water.
Claims (2)
1, a kind of material blanking tube exit automatic water jetting device for reducing dust, it comprises load-transfer device, it is characterized in that: be that sensor pendulum plate is installed in the discharging opening place above the load-transfer device, sensor pendulum plate upper end is that swing arm is connected with bearing chamber, on a side of swing arm, be welded with near plate, be installed on the sensor frame near switch, the line bag on the electromagnetic valve be connected on the circuit near switch series, weld with steelframe between sensor frame and the belt holder.
