Description

High Efficiency Exhauster {HIGH EFFICIENCY SKIMMER}

The present invention relates to an exhauster used to remove slag in molten iron ladle, and in particular, the slag skimmer arm is configured to have elasticity to effectively process slag without using the elasticity of the skimmer arm. It is related with the high efficiency exhaust machine which can be performed.

1 is a configuration diagram of a conventional slag skimmer, the slag skimmer is a slag skimmer arm (1) and hydraulic cylinder (2), skimmer arm running device (3), skimmer body (4) and swing hydraulic cylinder (4-1) Consists of. In order to remove slag, which is an inclusion in the molten iron, such slag skimmer is carried out by tilting the molten iron truck to 0 to 40 degrees. At this time, the driver operates the hydraulic motor 3-1 and moves forward and backward of the slag skimmer facility. Will be performed. As such, the slag skimmer arm 1 in the skimmer that removes slag consists of a single structure so that when the slag skimmer arm 1 operates to remove slag in the molten iron ladle 6, Since 1) moves in a rigid state, the exclusion effect of the slag is reduced, the blind spot in the molten iron ladle (6) has a problem that the slag is not excreted at all, which affects the quality of the molten iron.

In general, the slag removal process continues more than 70 times a day by the skimmer, and the repeated slag discharge efficiency decreases drastically due to repetitive work, resulting in poor quality due to delay in working time and increase in the molten iron content of slag. This is rapidly increasing.

The present invention was devised to solve all the problems of the conventional skimmer in view of the above situation, and the slag skimmer arm is configured to have elasticity, and after slaying the slag collected on the molten iron after a certain process in the molten iron ladle. The purpose is to provide a high efficiency exhauster that efficiently removes slag by using the elasticity of the slag skimmer arm in operation.

The present invention high efficiency exhauster for achieving the above object is provided with a slag skimmer arm (1) and a hydraulic cylinder (2), a skimmer arm running device (3), a skimmer body (4) and a swing hydraulic cylinder (4-1) In the skimmer, the slag skimmer arm 10 may be configured by connecting the first stage arm 10-1 and the second stage arm 10-2 with the pin 15 instead of the integrated slag skimmer arm 1. Supports 11, 11 ′, and 11 ′ are provided before and after connecting the first and second arms 10-1 and 10-2, and both supports 11 and 11 ′. Cylindrical sleeve (13) forming protrusions (12, 12 ') on the inner upper surface of the support (11), (11') between the) and prevents the spring from leaving the protrusions (12, 12 ') And (13 ') to install the spring (14) on the projections (12) and (12'), and the tension consisting of tension bolts on the second stage arm (10-2) behind the support (11 ') In addition to installing the device 16 on the base 18 The lower front end of the zone 11, 11 'fixed to the sseopoteu 17 welded to the lower face of the arm (10-2), characterized in that configured.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the subject innovation high efficiency exhauster.

Figure 3 is a block diagram of the high efficiency exhaust device of the present invention, Figure 4 is a block diagram of a slag skimmer arm according to the present invention. The present invention high efficiency exhaust machine is provided with the slag skimmer arm 10 shown in FIG. 4 in place of the conventional slag skimmer arm 1 shown in FIG. 2, and the slag skimmer arm 10 has a single stage arm 10-1. ) And a two-stage arm (10-2), and connects the first-stage arm (10-1) and the two-stage arm (10-2) with a pin 15 to form a slag skimmer arm (10), Supports 11, 11 ', and 11' are installed before and after the connection of the first and second arms 10-1 and 10-2, and both supports 11 and 11 'are provided. Cylindrical sleeve 13, which forms projections 12, 12 'on the inner upper surface of the support 11, 11' between and prevents the spring from leaving the projections 12, 12 ', ( 13 ') to form the spring 14 on the projections 12 and 12', and to adjust the tension of the spring 14 by the tension bolt of the tension device 16.

In addition, in order to prevent the first arm 10-1 from sagging downward, a support 17 made of a 30 mm steel plate is manufactured and fixed to the lower ends of the supports 11 and 11 'so that the second arm 10 -2) The first stage arm 10-1 is firmly placed on the support 17 by being firmly welded to the lower portion.

According to the present invention configured as described above, the slag skimmer arm 10 is separated into a first stage arm 10-1 and a second stage arm 10-2, connected by a pin 15, and a spring 14 is mounted on the upper portion. Suppression of the stiffness of the slag skimmer arm 10 generated during slag discharging by installing a floating up and down device is absorbed by the spring 14 and its connecting shaft, thereby increasing the discharging efficiency and reducing the quality due to the conventional slag. Is greatly improved and quality stabilization is expected.

The high efficiency discharger of the present invention facilitates the scraping of the slag when the slag skimmer arm 10 is naturally bent forward by the elasticity of the spring 14 when the slag is removed by the slag skimmer, and also when the slag is pulled forward while scratching the slag. The slag skimmer arm 10 is naturally extended so that a large amount of slag can be removed.

In order to remove slag which is an inclusion in the molten iron by slag skimmer, the molten iron truck is tilted to 0 ~ 40 degrees and slag is discharged. At this time, the driver performs the forward and backward of the slag skimmer facility along with the operation of the hydraulic motor (3-1). Done.

The slag skimmer is operated by a swing hydraulic cylinder (4-1) that moves left and right and a hydraulic cylinder (2) that moves the slag skimmer arm (10) up and down, and the slag injured on the molten iron ladle (6). To scrape the slag with the platen (7) fastened to the end of the slag skimmer arm (10) to drop into the slag port (5) placed in the lower portion.

The inventive high efficiency exhauster acting as described above separates the stiffness of the slag skimmer arm, which occurs when slag is removed, into the first and second stage arms, and the elasticity of the slag skimmer arm by the spring installed on the upper part. Since the slag excavation efficiency can be prevented due to rigidity, the slag excavation efficiency can be improved, thereby improving the quality of the product and stabilizing the facility.
