Description

  The present invention relates to an apparatus for automatically sprinkling water on a conveyor being transported on a conveyor and an automatic watering method using the same.

  In the steel manufacturing process, it is often used to transport transported materials such as raw materials using a conveyor.For example, a conveyor is also used when transporting coke produced at a coke factory to several hundred degrees Celsius to a blast furnace. Since this coke has a dusting property, the amount of dust in the atmosphere is reduced by removing the dust with a dust collector.

  However, when this dust collector is stopped due to breakdown or repairs, etc., it is necessary to prevent the dust from coking itself and to contain moisture appropriate for using the coke in the blast furnace. Therefore, it was necessary to adjust the moisture.

  Therefore, conventionally, a sprinkler is provided on the conveyor, and water is sprinkled while the coke on the conveyor is being transported to prevent dust generation and adjust the moisture.

  However, the conventional watering device uses On-Off control to open the solenoid valve and sprinkle water when the conveyor is in operation. In addition, there is a problem that the amount of water spraying cannot be adjusted according to the amount of transported material.

  Various proposals have been made regarding automatic watering devices. For example, Japanese Patent Application Laid-Open No. 2003-170085 discloses a method for detecting the transport amount of loose articles such as coal and changing the water spray amount based on the detected value. By doing so, a watering device that can always perform an appropriate amount of watering is disclosed.

  However, this device requires a detection system for the conveyance amount and a control system that changes the amount of sprinkling according to the detection value, and the equipment cost is high, and complicated control is required, so there are many failures. There was a problem with the reliability of the equipment.

  Drawing 1 is a figure which illustrates the process of applying the automatic watering device of the present invention.

  In FIG. 1, 1 is a conveyor, 2 is a watering apparatus.

  As shown in FIG. 1, for example, coke produced in a coke factory is charged into a blast furnace by a conveyor 1.

  At this time, if dust is emitted from the coke, dust is dissipated in the atmosphere and adversely affects the environment.Therefore, a watering device is provided near the exit of the coke factory. It relates to the watering method used.

  2-5 is a figure which illustrates embodiment of the automatic watering apparatus of this invention, FIG. 2 shows a front view, and FIGS. 3-5 shows a side view.

Reference numeral 10 denotes a tilting roller fixing part, 11 denotes a tilting roller base pipe (base), 12 denotes a spring, 13 denotes a spring strength adjustment part, 14 denotes a built-in pipe, 15 denotes a built-in pipe fixing part, and 16 denotes coke.

  FIG. 2 is a front view of an apparatus for automatically sprinkling water on a conveyed product on the conveyor of the present invention.

  As shown in FIG. 2, the present invention is an apparatus for automatically sprinkling water onto a conveyed product being conveyed on a conveyor 1, and a tilting roller 9 installed at the lower part of the conveyor 1 and inclined by the weight of the conveyed product, A tilting roller 9 and a spring 12 that is twisted by tilting the tilting roller 9 and the mount 11, and a water supply valve 5 that is opened and closed by a lever 8 connected to the tilting mount 11. It is characterized by having.

  When the conveyed product is placed on the conveyor 1, the tilting roller 9 is inclined by its own weight, so that the tilting roller mounting pipe (mounting frame) 11 rotates around the central axis and tilts. The spring 12 fixed to the roller mount pipe (stand) 11 is twisted, and stops when it is tilted to a certain range proportional to the weight of the conveyed product by the repulsive force of the spring 12. In the present invention, the structure and material of the spring 12 are not particularly limited, but it is preferable that the spring 12 has high strength and little deterioration of the repulsive force. Therefore, it is preferable to use a torsion spring including a spring as shown in FIG.

  A water supply valve lever (lever) 8 is connected to the tilting roller mount pipe (stand) 11 via a connecting rod 6 and a lever connecting portion 7, and the tilting roller 9 and the tilting roller mount pipe (stand) 11 are connected. Is tilted, the water supply valve lever (lever) 8 operates to open and close the water supply valve 5.

  FIGS. 3 to 5 are side views of an apparatus for automatically sprinkling water on a conveyed product on the conveyor of the present invention, FIG. 3 is a diagram showing the operation thereof, and FIG. 4 is a state in which watering is stopped. FIG. 5 is a diagram showing a state at the start of watering.

  The water supply valve lever (lever) 8 is a link mechanism as shown in FIGS. 3 to 5, and is a mechanism that rotates around a fulcrum. The water supply valve lever (lever) 8 is connected to the water supply valve 5. Since it is connected to the opening adjustment end, when the water supply valve lever (lever) 8 is pushed down, the water supply valve 5 can be opened automatically, and when the water supply valve lever (lever) 8 is pushed up, water supply The valve 5 can be closed automatically.

  In the present invention, the method of the water supply valve 5 is not limited, but it is preferable to use a flow rate adjusting valve excellent in flow rate controllability in order to accurately control the watering amount.

  Thus, in the present invention, since the water supply valve lever (lever) 8 is automatically operated by the dead weight of the transported material on the conveyor 1 to open and close the water supply valve 5, the transport amount per unit time of the transported material is reduced. Proportional watering can be maintained properly.

  Moreover, it is preferable to install several watering nozzles 3 in the traveling direction of the conveyor 1. By avoiding the belt side of the conveyor 1 to prevent water from splashing on the belt, the fall of the conveyed product on the belt can be prevented. Can be prevented.

  As shown in FIG. 2, the spring 12 is connected to a fixed built-in pipe 14, and the repulsive force can be adjusted by providing a spring strength adjustment portion 13 at the end of the spring 12. By adjusting the repulsive force, the amount of water spray can be adjusted.

  Further, by using the mechanism of the automatic watering device of the present invention, by pushing up the tilting roller 9, the cross-sectional shape of the conveyor 1 can be changed from a convex shape on the lower side to a convex shape on the upper side. Also, it can be used as a draining device for discharging water accumulated on the conveyor 1.

  Moreover, the sprinkling from coke can be prevented by watering coke using the automatic watering apparatus shown in FIGS.

  Furthermore, by adjusting the opening of the water supply valve in proportion to the amount of coke transported per unit time, and spraying the amount of water according to the amount of coke transported, the water contained in the coke is used for blast furnace operation. It can be controlled within the range of 8% or less without any problem.

  In addition, by linking the automatic watering device of the present invention with the operation signal of the dust collector, for example, when the dust collector is stopped, the watering device can be automatically operated.

  Furthermore, the operation information of the automatic watering device of the present invention can also be used as means for detecting a conveyance state such as the out-of-load of a conveyed product.

  An embodiment in which the automatic watering device of FIGS. 2 and 3 is applied to coke is shown below.

本実施例においては、散水量を１０（T/H）としたところコークスの搬送中に自動的に散水することができ、コークスからの発じんを散水しない場合に比べて８３〜９４％減少させることができた。

In this embodiment, when the amount of water spray is 10 (T / H), water can be automatically sprinkled during the conveyance of coke, and the dust from the coke is reduced by 83 to 94% compared to the case where water is not sprinkled. I was able to.

  Moreover, the water | moisture content in coke was 8% or less suitable for blast furnace operation.
