Description

Dust collector {Collector}

The present invention relates to a dust collector, and more particularly, to collect the equipment (for example) (fine) dust generated from the exit (guide) of the wire rolling mill, (secondary) scale and the like by using water efficiently It relates to a dust collecting device to be treated with.

Typically, wire rod rolling is to produce a circular wire rod coil using a pair of ball-type rolling rolls, and includes an inlet guide on the inlet side of the rolling mill and an outlet guide on the outlet side of the rolling mill.

Guided rolling material is precisely guided to the rolling mill by the inlet guide, and the rolling is made. The rolling material is completed by rolling the ball to the next rolling mill by the exit guide. This is done.

However, the exit guide disposed on the outlet side during the rough rolling of the wire is disposed close to the exit of the ball roll in order to prevent the case that the rolled material is released from the ball rolling roll, the shape of the exit guide is tunnel type pipe exit guide It is provided and guides and guides the rolled material accurately to the next rolling mill, which is usually scattered while being discharged from the exit side of the exit guide because the secondary scale occurs as the recrystallization of the rolled material grows after hot rolling.

Therefore, it is necessary to collect and remove scales scattered from the exit guide of such a wire rolling mill because the scales scattering contaminate the surrounding equipment or the working environment.

For example, FIG. 7 schematically shows a scale dust collection state during rough rolling of a conventional wire rod.

That is, as shown in Fig. 7, the pair of ball rolling rolls 112 are installed on the stand 114 of the wire roughing mill 110 up and down, and each inlet guide 120 described above at the entrance and exit side thereof. ) And the outlet guide 130 are disposed corresponding to the path of the rolled material, which is mounted on each of the inlet and outlet side guide holders 122 and 134 installed in the rolling stand 114. In addition, cooling water is sprayed through the nozzle 116 to a rolling roll.

Therefore, when the rolled material 100 is extracted from the outlet guide 130, since the secondary scale as well as the fine dust and the like are scattered as described above, the suction duct connected to the dust collector 140 adjacent to the outlet guide 130. 150 is disposed.

At this time, the fan facility 142 of the dust collector 140 is operated, and the scale, dust, etc. sucked through the suction duct are processed in the dust collector.

However, in the case of a conventional dust collector 140 that generates suction pressure using such a conventional fan to collect scale or dust, the scale and dust sucked into the dust collector are sprayed with water inside the dust collector. Together with the external discharge method, the scale or dust is simply processed while passing through the area for spraying water, so that residual scale or fine dust is discharged externally without being completely collected through the dust collector outlet. .

Alternatively, although not shown in a separate drawing, in the other method of removing the fine dust or scale by installing the filter in the dust collector, filter clogging is frequent, so that the filter inside the dust collector is periodically cleaned to maintain a constant dust collection efficiency. Need to replace and manage.

As a result, in the conventional method of spraying water or using a filter, dust collection efficiency is lowered in the related art, and maintenance and maintenance such as continuous replacement of parts (filters) is required to maintain a certain efficiency.

In addition, although schematically illustrated in the drawings, in the case of water injection or a filter, a dust collector (filtration) space is required for a certain time, so that the dust collector installation structure is very large to maintain the dust collector capacity stably, which is difficult to install in a desired limited place. There was this.

Therefore, in the art, it is possible to treat dust-collected material such as scale generated in the dust or rolling process by a water bath method that is collected and treated in water, to reduce the size of the facility and to install it in a desired place, while maintaining excellent dust collection efficiency. In addition, there has been a demand for a dust collector that can operate the device very easily in an automated state.

In order to realize the above technical problem, an aspect of the present invention, the apparatus main body is supplied with water for the treatment of the dust to be collected, the dust-collecting unit input means associated with the apparatus main body, and the inside of the apparatus body At least one dust collection means for providing at least one provided to process the input dust collected,
The dust-collecting means may further include at least one dust-collecting container provided inside the apparatus main body and provided with a pressure to the apparatus main body to pass through the dust-collected material so as to be discharged to the outside with a water bath. and,
The dust collector is provided with a plurality of dust collectors sequentially provided in a vertical direction in the apparatus main body to enable the collection process for each particle size of the dust collector, and the dust collector passes through and collects the water with the dust collected therein. And, it provides a dust collector further provided with an inclined surface provided to facilitate the external discharge through the collection of dust collected.

Hereinafter, the present invention will be described in detail with reference to the drawings.

First, Figures 1 to 4 show the dust collector 1 according to the present invention.

For example, the dust collector of the present invention is an example of the configuration, the device main body 10 is supplied with water for the treatment of the dust collected (see '2' in Fig. 2a), and the device main body 10 It may be configured to include a dust-collecting material input means 30, and the dust-collecting material processing means 50 is provided in the inside of the apparatus body to provide at least one dust to be treated.

Therefore, the present invention is filled with water in the device, and the dust (2), such as scale, dust, which is forcibly introduced at a pressure higher than the hydraulic pressure is sent upward through the device, at this time through the treatment means (50) It is discharged externally with water, so that it remains in a manner different from that of a conventional water jet or filter, so that dust collected is not generated. That is, in the following description of the present embodiment, the apparatus of the present invention will be described as a water-based dust collector 1.

For example, when the water pressure of the water supplied to the apparatus main body 10 of the present invention to form a certain level in FIG. 1 is 0.2 kg / cm 2, as described in detail below, the apparatus through the feeding means 30 is described. If the dust 2 to be introduced into the main body 2, that is, the dust, scale or air pressure is maintained at approximately 0.9 kg / cm 2, the dust to be forcibly raised from the lower part of the apparatus main body to the upper part, and the treatment The collected dust dispersed while passing through the means 50 is continuously discharged together with the water through the external discharge of the water.

On the other hand, as shown in Figures 1 and 3, the apparatus body 10 of the present invention is provided in a cylindrical shape on the support (10a) and the lower portion is an inclined conical steel plate structure, the upper air outlet 12 ) Is formed with a cover 14 formed thereon.

At this time, the apparatus main body 10 is associated with a water level corresponding water supply means 70 for supplying water for the operation of the water bath dust collector (1).

That is, as shown in Figures 1 and 3-4, the water supply means 70 is provided on the inner upper portion of the apparatus body, floating level detection means 74 (specifically, rising or falling depending on the water level) May be provided as a float and a sensor operated when the float is lowered) and a water supply pipe 72 having a control valve 76 electrically connected through the apparatus control unit C is mounted along the side of the apparatus body. .

In addition, the water supply pipe 72 is connected to one or more water supply ports 78 corresponding to the positions of the distribution type collecting tanks 52 and 54 of the processing means 50 described below, and the water supply port is an apparatus. It is provided in a watertight structure through the body.

Accordingly, when water is continuously supplied to the inside of the apparatus main body 10 through the operation control of the control valve 76 through the apparatus control unit C, and the water is discharged to the outside as the dust collected, the water level is lowered. Automatically supplied to maintain a constant level at all times.

Maintaining such a water level is important, because if the water level is excessively lowered, it is not treated in the water-collected matters through the treatment means 50 and is discharged to the outside like air. In other words, maintaining an appropriate water pressure is because the dust to be treated is discharged externally in a water bath like water.

Next, in the present embodiment, the water-based dust collector 1 of the present invention is described as an example in which the dust-collected matter is generated as a wire roughing mill (110 of FIG. 7) in which the scale described above is generated, but of course necessarily. Of course, it is not limited and can be used throughout the industry where only dust is generated.

Meanwhile, FIGS. 1 and 2 show dust collecting means 90 of the apparatus of the present invention, which is connected to the outlet guide 130 of the rough rolling mill 110, which is a facility in which dust is generated. The means 90 is associated with the device body input means 30 of the dust collected.

That is, the dust collecting means 90 is connected to the suction duct 92 surrounding the outlet guide 130, which is an example of the facility, and the suction duct and the pipe 96, and the input pipe of the input means ( 32 includes a blowing 94 to which it is associated.

At this time, as shown in Figure 2, for example, the outlet guide 130 is formed with a hole 132 on one side or in all directions, so that the suction force during the operation of the blowing 94 of the wire rod passing through the outlet guide 130 In the extraction section, the scale, dust, etc. are sucked (suction) and supplied to the input pipe 32.

Preferably, as shown in Figure 1, the blowing 94 of the suction means is associated with the device control unit (C), the pressure gauge 34 in the inlet pipe 32 of the dust input means 30 ) Is installed and associated with the device control unit (C), it is possible to control the input pressure of the dust to be injected into the device body through the input pipe.

Therefore, the device control unit C will control the supply amount of water supplied to the device main body and the device main body injection pressure of the dust to be collected to enable the optimum dust treatment.

In this case, as described above, the input pipe 32 is connected to the blowing because the dust is forced out from the bottom of the main body of the device filled with water to rise as air in the water while being discharged by hydraulic pressure. It is necessary to be connected to the bottom inclined bottom side of the device body (10).

Next, FIGS. 1 and 4 to 5 illustrate the dust-collecting material processing means 50 which makes it possible to collect and process the dust-collected substance which is substantially added in the water-based dust collector 1 according to the present invention. have.

For example, in the apparatus of the present invention, the dust-collecting means 50 is provided inside the apparatus main body 10, and the dust-collected substance injected with the pressure of the apparatus body is dispersed and passed through the water bath system. And one or more dust collectors provided for external treatment.

Preferably, as shown in Figures 1 and 4, 5, the dust collecting container is provided with two 52, 54 in the vertical direction in order to distribute the dust to be collected by particle size For example, in the collection vessels 52 and 54, holes 52a and 54a are formed in a predetermined pattern, through which the collected dust is introduced and collected into water. The inclined surface includes an inclined surface (unsigned) which provides smooth external discharge through the collection of the dust collected.

For example, as shown in FIG. 5, the lower inclined surface of the collecting container is inclined at about 30 ° (θ) so that the collected material flows smoothly together with the water flowing along the inclined surface (bottom surface) of the collecting container. It is externally processed through the discharge pipe 56 disposed through the center.

That is, the discharge pipe 56 penetrates the center of the device body 10 so that the lower end thereof is extended outwards through the center of the inclined bottom of the device body, and the discharge pipe is formed through the holes 60 provided at the center of the collection containers. In communication.

In addition, a lower end of the apparatus main body of the discharge pipe 60 is provided with a control valve 58 which is electrically connected to the apparatus control unit C and operated as shown in FIG. 1.

Therefore, the amount of water + dust collected through the discharge pipe is adjusted according to the operation control of the control valve, and the opening degree control of the control valve is usually performed so that some water continuously flows.

At this time, if the amount of water is excessively high, the amount of water supplied must be increased. On the contrary, if the amount of water is too small, the collected dust 2 collected in a water bath accumulates, which may cause a problem in that it cannot be smoothly discharged. .

Therefore, the collection tanks 52 and 54 of the treatment means 50 of the present invention are filled with water in the inner space in the form of a cone, but are discharged only through the holes 60 of the discharge pipe 56, so that the bottom of the collector inclined floor Water and dispersion collected dust along the surface is discharged to the outside, and since the dust and air pass through only the dispersed holes of the collecting vessels, the dust and air are dispersed while passing through the dispersed holes. In this case, the dispersed dust is mixed well with water and discharged outside.

For example, FIG. 6 shows the location of the aperture 60 of the discharge conduit 56, which is associated with the collection vessels 52 and 54 in contact with the bottom of the collecting vessel and thus water is discharged only through the apertures 60. do.

Next, as shown in Figures 1 and 4,5, the present invention is connected to the discharge hole 60 formed on the upper side of the discharge pipe and the upper collecting tank for further collecting the final dust collected in the water (64) may be further included.

In addition, it may further include a condensate collection tank 66 which is provided to communicate with the upper end of the discharge pipe to collect the condensate in the discharged air.

In particular, the apparatus of the present invention is further provided with a derivative (68) disposed on the outer edge of the condensate collection tank 66 to form an air induction passage (68a) for inducing air to the air outlet 12 provided in the apparatus body Can be.

Therefore, the air raised through the collectors is scattered outside through the air inlet passage 68a through the central outlet 12 of the apparatus main body, and the fine dust or scale dust contained in the air is collected in the upper collector ( Finally, further collected in 64, the condensate contained in the air may be discharged through the discharge pipe 56 through the condensate collector (64).

At this time, the operation of the water-based dust collector 1 of the present invention described so far, the suction associated with the equipment associated with the device, for example, the suction means 90 connected to the outlet guide 130 of the wire roughing mill 110 The dust-collected material 2, such as the fine dust and the secondary scale, has a uniformly distributed hole of the collection cylinders 52 and 54 of the processing means 50 provided in two rows inside the apparatus main body together with air. Dust or scale having a specific gravity greater than water or air while passing through the water having a constant pressure and dispersed through the water under pressure does not go from the water to the bottom of the collecting container, and at this time, the water discharges the discharge pipe discharge hole 60. It is discharged together when discharged through.

Next, the remaining fine dust and fine scale, which are raised to the pressure through the primary collector through which the pressure is applied due to the fine particle size, are dispersed again through the secondary collector and discharged together with the discharge of water. Finally, air is discharged through the device outlet.

At this time, through the opening degree control of the control valves provided in the pipes described above, the water is continuously discharged in a small amount and at the same time, the water is supplied to make the water level constant. The input pressure of the apparatus main body of the dust-collected material and the water pressure of water can be appropriately maintained by controlling the blowing 94 and the water level, respectively.
