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 constant watering pressure at all times by automatically adjusting the watering amount according to the transport amount of the transported material and controlling the nozzle water amount 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 illustrated 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. The water is sprayed through the constant spray nozzle 6 installed in the upper part and the chute.

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

Accordingly, the transported material (7) is a structure that can be detected by touching only the appropriate height state, so when the transport (7) is detected, the electric valve (4) is 100% open only at the detected moment (Fig. Since only one condition can be sprayed irrespective of the change in the transport volume such as), bamboo ore due to excessive watering is generated in the transported cargo (7), and it flows down the slope of the belt conveyor during transportation. There was this.

In addition, as shown in (a) of FIG. 1, since the detection target 2a is not in 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 sprayed using the dropping angle and the dropping 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 same way, if the cargo is not loaded during transportation of the raw materials and raw materials 7, the dropping force is not applied to the object detection target 2a. Thus, the weight box 12a weights the weight of the weight box 12 by the weight box 12. 12) is a down action so that when the force acts on the ore amount detection bar (2f) connected to the weight box 12 and the connection wire 10 accordingly, the target rotation axis (2b) is rotated in the weight direction to detect the integral The target 2a acts in the pulley 9a direction As the adjustment bar 3b fixed to the target rotating shaft 2b is rotated, the valve adjustment bar 3b connected to the wire rope 10 is operated by the return force by the weight of the weight box 12. 3b) rotates to the stopper, closes the valve, and stops 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, so that a problem of the inability to maintain a uniform spraying pressure that can penetrate into the drop transport 7 occurs.

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

Accordingly, the present invention has been made in view of the above-mentioned problems, and the sprinkling device for preventing dust scattering generated during transportation of lead 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.
