Description

Quantity control water apparatus for nozzle division type

The present invention relates to a nozzle split type watering sprinkler in a raw material processing facility, and more particularly, it is possible to maintain a constant sprinkling pressure at all times by automatically adjusting the sprinkling amount according to the amount of transported material and controlling the nozzle quantity of the spray nozzle. A nozzle split water control sprinkler system is provided.

In general, iron ore and coal used as raw materials and fuels 7 are transported and processed using a belt conveyor in a steel mill process, and dust scattering generated in this transport process is a major cause of environmental pollution in steel mills.

As shown in FIG. 1, the detection target 2a of the ore amount detection unit 2 detects the transport 7 transported during the transport operation of the transport 7 to the carrier belt 1 of the belt conveyor. As the target rotation shaft 2b is rotated by the contact force, the limit touch bar 2d installed in one direction of the rotation shaft touches the detection limit switch 2e, and the detection state is transmitted to the electric valve 4 as an electric signal to the belt 1. It is a structure to spray water through the spraying spray nozzle (6) installed in the upper and chute.

In the conventional watering device having such a structure, the transport object detection target 2a for detecting the transport object is fixed to the average height of the transport object 7.

Accordingly, only the appropriate height state of the transported material 7 to be transported has a structure that can be sensed. When the transported item 7 is detected, the electric valve 4 is opened 100% only at the detected moment. As a), irrespective of the change in the transport volume, only one condition is carried out and the water is sprayed. Therefore, bamboo ore and bamboo charcoal are generated due to excessive watering in the transported goods, and the coal-fired coal flows from the belt conveyor slope during transportation. There was a problem.

In addition, as shown in (b) of FIG. 1, since the detection target 2a does not come into contact with the electric valve 4, the water spray signal is impossible, and the air pollution is caused by dust scattering due to the water spraying in a limited condition that is 100% closed. The problem is conventionally used in the method of spraying water using the falling angle and the falling force in the chute 9 of the transported material 7 transported to the carrier belt 1 of the belt conveyor during the transport operation. In the above method, if the transport material is not loaded during the transport operation of the soft and raw material 7, as shown in FIG. 2, the drop force is not applied to the transport detection target 2a, so that the weight box 12 of the weight case 12a When a weight acts on the ore amount detection bar 2f connected to the weight box 12 and the connection wire 10 as the weight box 12 is down by the weight, the target rotation shaft 2b is moved. Since it rotates in the weight direction, the detection target 2a is integrated. As the adjustment bar 3b fixed to the target rotation shaft 2b rotates in the direction of the pulley 9a, the valve adjustment bar 3b connected to the wire rope 10 returns by the weight of the weight box 12. Under the action of the force, it rotates to the stopper and closes the valve to stop the watering.

On the contrary, the spraying operation opens the manual valve 3 by operating the adjustment bar 3b of the manual valve 3 while the operation of the ore amount detection unit 2 pulls the weight box 12 when the transport drops. The opening amount of the manual valve 3 is changed according to the amount of transport of the ore and the water is sprayed by adjusting the watering amount.

Conventionally operating as described above, as shown in Fig. 2 (b) (c) to control the operation of the adjustment angle of the adjustment bar (3b) of the opening and closing of the manual valve (3) in accordance with the transport amount of the material (7). Since the spraying amount is adjusted, irregular spraying pressure is generated in the spraying force sprayed from the spray spray nozzle 6, thereby causing a problem in that it cannot maintain a uniform spraying pressure that can penetrate into the drop transport 7.

In addition, there is a problem that a large amount of dust, scattering occurs in the lower belt conveyor by the irregular sprinkling of the entire surface portion of the transport material (7) falling as shown in FIG.

Accordingly, the present invention has been made in view of the above-described problems, and the sprinkling device for preventing dust scattering generated during transportation of soft and raw materials to a belt conveyor in the raw material processing facility of the steelmaking process is automatically adjusted according to the amount of transported water. The purpose is to maintain a constant spraying pressure at all times through the nozzle quantity control of the nozzle is injected and adjusted.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
