Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic mud supply device that automatically supplies mud to a mud gun for blocking a blast furnace taphole.

Conventionally, mud has been supplied to the mud gun by manual supply means or automatic supply means using a device.

Problems that @Ming is trying to solve However, manual feeding methods not only make the work complicated and require heavy labor, but also have problems such as the work environment being bad and dangerous because the work is done near the blast furnace. Ta. On the other hand, when using an automatic feeding device, the problems encountered with manual feeding can be eliminated, but with conventional devices, the mud is preformed into a shape that can be fed automatically at the manufacturing process stage, and then
The construction pressure is such that this is transported to the construction site and supplied to the mud gun, so in the mud manufacturing process,
It is necessary to automatically pack and automatically align the mud, which has been formed into a predetermined shape, in a predetermined position on a pallet, and at the construction site, for example, if it is stored near a blast furnace (where the temperature is high), it will soften and form a predetermined shape. Since it cannot maintain its shape, it must be stored in a cool place away from the blast furnace. (A distance is created, and this distance I
It is necessary to install an automatic transport line to pack the I, which increases the size of the equipment, which in turn causes a rise in construction costs.Furthermore, as the equipment becomes larger, there is a restriction of approximately υ in terms of installation space. For this reason, the spread of automatic feeding devices is still low, and manual feeding currently occupies the mainstream.

The present invention has been made with the aim of eliminating such drawbacks of the conventional technology.

The present invention relates to a mixed wire mud delivery device equipped with a heater, an extrusion molding machine that pressurizes and extrudes the heated and softened mixed wire mud delivered from the delivery device into a rod shape, and a rod-shaped mud extruded from the above extrusion molding machine. The present invention relates to an automatic mud supply device, which is equipped with a cutting mechanism for cutting mud into a predetermined size, and a mud gun is installed to receive the cutting mud material falling under its own weight from the cutting mechanism.

According to the apparatus of the present invention, the kneading mud is supplied to the extrusion molding machine in a heated and softened state from a delivery device equipped with a heater, and is formed into a rod shape, which is then cut into a predetermined size by a cutting device. However, by allowing the mud to fall downward under its own weight, it is possible to automatically supply mud to the mud gun installed below the cutting mechanism. Therefore, the mud can be transported from the manufacturing factory to the construction site by filling it into cans, for example, and there is no need for the troublesome work such as automatic packaging and automatic alignment that is required with conventional equipment that molds the mud into a predetermined shape at the manufacturing factory. I don't. In addition, since the cutting mud is directly loaded into the mud gun while falling under its own weight, there is no need to install an automatic conveyance line to the mud gun, which is required with conventional equipment, making the equipment smaller and reducing construction costs. It is possible to reduce the size and installation space.

An embodiment of the present invention will be described below based on the accompanying drawings.

As schematically shown in FIG. 1, the device of the present invention is a cross-conducting mud feeding device equipped with a heater (1). ! (
2) An extrusion molding machine (3) that presses and extrudes the heat-softened kneading mud (a□) delivered from the delivery device (2) into a rod shape, and a rod shape extruded from the extrusion molding machine (3). It is equipped with a cutting machine 111 (4) that cuts the mud (a2) into a predetermined size, and a mud crab/(5) is installed to receive the cut mud material (a3) falling under its own weight from the cutting mechanism (4). . (Ugh, Mud Gun (5)
) Cutting mud material (A3) in the mud receiving hopper
It is placed on the dead weight fall line of .

Figures 2, 3, and 4 show details of the delivery device (2) with heater (1). 56-9527
◇The illustrated delivery device [(2) is a vertically oriented rotating circle Wi? υ, and a fixed table (goods) for closing the lower end opening of the rotating cylinder (CI);
) At least one feeding blade (2) is installed in one radial direction with a gap (to) between it and the fixed table (A). ) is formed at the discharge port, and the edge on the rear side in the rotational direction of the discharge port (C) is provided with a blade plate 4 having a leading edge portion (264) projected within the above-mentioned distance.

The figure shows a heating tube type as the heater (1) provided in the delivery device (2), and in addition to the heating tube (b), a heating plate is provided on the underside of the fixed table (2). It's okay.

As the extrusion machine (3), various known types can be used, and its structure is not particularly limited as long as it can continuously extrude mud into a rod shape.

Details of the cutting mechanism (4) are shown in FIGS. 5 to 7, and the rod-shaped mud (a
When the tip of the link cutter (2) hits the limit switch (see Figure 7), the cutting blade (43g) of the link-shaped cutter is rotated 120 degrees, and the rod-shaped mud (lz2) is rotated by 120 degrees. ) is structured to cut. Other types of cutting mechanism (4) may also be used.

Using the device of the present invention, mud is automatically supplied to the mud crab/(5) K11t, and as shown in FIG. 1, the mixed mud (d) is supplied into the exit device (2). After the crosstalk mud (d) is manufactured, it is filled in cans, for example, and transported to the construction site, and is fed manually or automatically and mechanically into the rotating cylinder of the delivery device (2) at the time of construction.

The mud (d) supplied into the delivery device (2) is preheated by the heater (1) to about 0 to 80°C (0 to 80°C) and softened to a hardness suitable for cutting. It takes about 30 to 40 minutes in winter and 20 to 25 minutes in summer, but normally it takes about 120 minutes to tap a blast furnace and close the tap hole.
Since it is carried out at intervals of ~180 minutes, it can be carried out sufficiently using this interval time.

After preheating, the mud (d) is cut out from the delivery device (2) and fed to the extrusion molding machine (3) to form a rod shape, and this rod-shaped mud (1! 2) is cut into a predetermined size by the cutting mechanism (4). By cutting the mud into mud crabs,
(5) Can be automatically supplied. In this case, cutting mud material (A3
) It is convenient to measure the weight per unit in advance because the amount of charge can be determined based on the quantity supplied.

Effects According to the device of the present invention, the mud can be cut into a predetermined shape at the construction site and then directly supplied to the mud gun, making the device compact and reducing the size of the device and the installation space. It not only provides a total of 9 benefits, but also reduces construction costs, and has features that can contribute to the competition of automatic mud supply devices.
