Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to a mineral cotton manufacturing equipment including a cotton making device and a cotton collecting device, when manufacturing mineral cotton using centrifugal force and/or air fluid pressure. This invention relates to a device that continuously discharges generated granules to the outside of the system.

[Conventional technology]

In the cotton manufacturing and cotton collecting equipment of conventional mineral cotton manufacturing equipment such as rock wool, the molten mineral discharged from the melting furnace (not shown) is passed through the trough 1 as shown in Figure 2.
leads to cotton milling machine 3. The cotton machine 3 is installed on a movable cotton machine cart 2 so as to be located below the tip of the trough 1. The molten mineral is turned into fibers by the centrifugal force and/or air fluid pressure (by compressed air from the air plenum device 4 installed below the cotton machine 3) by the cotton machine 3, and is blown away and collected. They are accumulated in layers on a net conveyor 6 in a chamber 5. Note that, for this purpose, a downdraft fan (not shown) is provided.

On the other hand, glass particles (particle size > φ0.5 mm) produced during cotton milling in this cotton machine, unmelted matter in the melting furnace, and slag lumps adhering to the trough, which have a negative impact on the product, are transported to the net conveyor 6. A drum 7 is provided between the cotton mill 3 and the net conveyor 6 to prevent the cotton from adhering to the cotton and mixing with the product.

The agglomerates that have adhered to and accumulated on the drum 7, the agglomerates that have not reached the drum 7, and the molten materials that have fallen from the trough without falling into the cotton machine are transferred to the opening between the cotton machine 3 and the net conveyor 6. It falls and accumulates on the ground.

After cooling, the work of discharging the granules and molten material that have fallen and accumulated at the openings between the cotton machine and the net conveyor is carried out manually using a shovel car.

[Problem that the invention attempts to solve]

When using such conventional equipment, it is necessary to secure a work path for the shovel car and to take safety measures against high-temperature granules scattering from the opening between the cotton machine and the net conveyor. This increases the area required for the equipment.

Furthermore, even if an attempt is made to create an upward flow through the suction of a downdraft fan in this opening to re-float the fibers and improve the collection yield on the net conveyor, since the drum 7 is fixed, there will be no flow on the drum. Fibers attach, grow, and fall. Further, since fibers that do not reach the net conveyor fall, the cotton collection yield is low, and furthermore, it is necessary to take measures to prevent the generation of dust from the fibers above ground.

This invention aims to improve the fiber collection yield and make the required area of the equipment more compact by using a continuous cooling discharge method for discharging the granules generated in the melting furnace and cotton collecting equipment of mineral cotton manufacturing equipment. be.

[Means for solving problems]

In order to achieve the above object, the present invention provides a mineral cotton manufacturing equipment including a cotton making device and a cotton collecting device, in which a water-cooled drum is provided between the cotton making device and the cotton collecting device, and the water-cooled drum is A chute is provided surrounding the chute, at least a portion of the chute located below the cotton manufacturing device is water-cooled, openings are provided at appropriate locations in the chute, and a water-cooled conveyor is further provided at the lower end of the chute. This is a granule discharge device in a cotton collecting section of a mineral cotton manufacturing facility, which is characterized by the following.

[Effect]

A chute is provided below between the cotton-making device and the cotton-collecting device, at least a portion of the chute located below the cotton-making device is of a water-cooled structure, and a water-cooled conveyor is provided at the lower end of this chute, thereby making it possible to make cotton. High-temperature agglomerates such as glass particles, unmelted materials in the melting furnace, and slag adhering to the trough fall below the cotton-making equipment, but they do not scatter to the outside and are automatically cooled and removed from the system. Target and continuous discharge.

In addition, by providing an appropriate opening in the chute to suck outside air and further providing a water-cooled drum inside the chute, the passage cross-sectional area of the sucked air is reduced, so the flow rate in this water-cooled drum portion is reduced. The fibers that have fallen without reaching the cotton making device will also float again, making it easier for them to be collected in the cotton collecting device.

〔Example〕

An embodiment of the present invention will be described based on FIG.

In the figure, the same numbers as in FIG. 1 indicate parts having the same parts and functions as those described in FIG. Alternatively, the fiberized portion is deposited on the net conveyor 6 by the air-fluid pressure.
On the other hand, agglomerates that have a negative impact on the product, such as glass particles produced when collecting cotton in the cotton mill, unmelted matter in the melting furnace, and slag lumps that adhere to the trough, and molten matter that does not fall into the cotton mill, are The cotton falls between the cotton machine 3 and the net conveyor 6, but for this purpose, a rotating water-cooled drum 7a is provided between the cotton-making machine 3 and the net conveyor 6, and this water-cooled drum 7a is surrounded and collected. A chute 9 is provided.

A screw conveyor 8 having a water-cooled structure is provided at the lower end of the chute 9. A portion of the chute 9 located below the cotton machine 3 is a chute 9a having a water-cooled structure. This is divided into multiple stages in the height direction, and the space between the upper and lower water cooling chutes 9a is designed to prevent falling objects from spilling outside of the chutes 9.
A gap is formed. Further, the chute 9 is provided with an appropriate number of air intake ports 11 having an appropriate area in order to ensure an upward flow velocity in the water-cooled drum 7a portion (the portion indicated by A in the figure). Note that 10 is a liner.

By having the above configuration, the cotton milling machine 3
The granules and molten material that have fallen between the net conveyor 6 and the water-cooled chute 9 are received by the chute 9 including the water-cooled chute 9a and the water-cooled drum 7a, and are continuously discharged to the outside of the system while being cooled by the water-cooled screw conveyor 8.

Furthermore, the fibers that have fallen between the cotton milling machine 3 and the net conveyor 6 rise again to the surface and are accumulated on the net conveyor 6 because the upward flow rate increases in the water-cooled drum 7a section.

[Effect of idea]

According to the device of the present invention, the agglomerates and molten materials that have fallen between the cotton machine and the net conveyor are controlled and cooled by the water-cooled chute, water-cooled drum, and water-cooled screw conveyor, and are continuously discharged from the system. Human work can be omitted, improving work efficiency.

Furthermore, since the lower part of the cotton machine has a chute structure, it is possible to prevent high-temperature granules from scattering, and no space is required for safety.

In addition, since the work path of the shovel car can be deleted, the lower part of the cotton milling machine can be used effectively, and as a result, the area required for the equipment can be made more compact.

In addition, the fibers are re-floated by the upward flow velocity introduced from the air intake port by the suction of the downdraft fan, and the cotton collection yield is improved. , fibers that are sent downward without growing and do not reach the net conveyor also fall near the water-cooled drum, but the upward flow rate in section A in Figure 1 becomes faster, so
Only the falling fibers can be floated and accumulated on the net conveyor. In other words, the present invention further improves the cotton collection yield compared to the conventional technology.

Furthermore, as mentioned above, the chute structure prevents particles from scattering, and the negative pressure inside the chute prevents fibers from scattering, making it a great contribution to environmental protection.
