The present invention relates to an apparatus for automatically inputting a coagulant used as an auxiliary material for specimen combustion into a crucible, and more particularly, to increase the combustion efficiency of the specimen in the process of melting and burning the specimen injected into the crucible using high frequency. The present invention relates to an automatic fuel injection device for inputting a fuel consumption amount used in a predetermined amount unit.

In general, the combustion method is mainly used for the determination of carbon or sulfur of a specimen such as steel, and the combustion method can be classified into several types according to the measurement method, but the infrared absorption method combining the high-plate combustion method and the infrared detector is analytical operation. It is widely used because of its simplicity and speed.

As shown in FIG. 1, the analysis apparatus used in the infrared absorption method includes a specimen combustion unit 51, a dust collecting unit 53, an infrared detection unit 55, a data processing unit 57, and the like. . The specimen combustion unit 51 burns the specimen contained in the crucible using high frequency. When the analytical specimen is burned in a high frequency manner in the analyzer, carbon is burned in the state of CO or CO ₂ and sulfur is burned in the state of SO ₂ , and this combustion product is detected by the infrared detector 55 and an analysis value corresponding to each concentration is obtained. It appears in the data processing section 57.

The infrared detection unit 55 utilizes a gas to be quantified and a kind of light absorption reaction generated by this wavelength. For example, CO or CO ₂ and SO ₂ in the molecular state received by infrared light absorb light of a wavelength corresponding to its own vibration and rotation. Therefore, even though CO, CO _2, and SO ₂ are mixed, the wavelengths of absorbing light (CO = 4.7 μm; CO ₂ = 4.3 μm; SO ₂ = 7.4 μm) are different. Can be measured simultaneously.

On the other hand, the specimen combustion unit 51 uses a supporting agent to help the combustion of the specimen. In other words, the test piece was introduced after the predetermined amount of the coagulant was introduced into the crucible, and after that, the test piece was burned by using a high frequency method.

However, since the input of the supporting agent is generally performed by a worker who uses the tool for inserting the supporting agent (a, b; see FIG. 3) as shown in FIG. 2, the input amount of the supporting agent is not constant. Differently depending on the worker. That is, the combustion effect decreases depending on the amount of the supporting agent, and as a result, the reliability of the data due to the deviation of the component data of the combustion product is reduced. In particular, there is a problem that causes an error when analyzing trace elements.

The present invention has been made to solve the conventional problems as described above, according to the data of the gas component generated as a result of the combustion of the specimen by maintaining a constant amount of the aid to be injected into the crucible to assist the combustion of the specimen It is an object of the present invention to provide a fuel repellent input device capable of improving reliability.

In order to achieve the above object, according to the present invention, the apparatus for injecting the coagulant into the crucible for burning the specimen is a housing in which the storage hopper for the storage medium is located on the upper side and the one side is open, the lower portion of the storage hopper A plurality of grooves rotatably embedded in the housing and formed with a plurality of grooves having a predetermined depth along the outer periphery, into which a plurality of grooves having a predetermined depth into which the repellent falling from the storage hopper flows; Located in the lower side of the side is characterized in that consisting of a guide member for guiding the flame retardant falling from the groove to the crucible as the rotor rotates.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

First, the fuel repellent injector according to the present invention has a protective box that protects the control system 8 for controlling its operation, and a storage hopper in which the flame retardant to be added to the crucible 23 is stored on the upper part of the protective box. There is provided a housing 5 having (1) thereon. A sample basis weight 25 is provided at the front lower portion of the housing 5, and a crucible seat 24 at which the crucible 23 is seated is provided at an upper portion of the sample basis weight 25. Around the crucible seat 24 is provided a detection sensor 21 for detecting a seating state of the crucible 23.

The housing 5 includes a disk-shaped rotating body 6 positioned below the storage hopper 1, and an accommodating groove for accommodating the supporting medium falling from the storage hopper 1 in the outer circumference of the rotating body 6. (7) is provided. The rotating shaft of the rotating body 6 is provided with a shaft 13 which penetrates the side of the housing 5 and extends to the outside, and a driven pulley 11 is provided at the outer end of the shaft 13. The driven pulley 11 is provided with a plate 14 radially, the sensing means 16 having a sensor 15 for sensing the plate 14 to rotate in conjunction with the rotation of the driven pulley 11 is a control system It is installed adjacent to the plate 14 on the protective box. The sensor 15 of the sensing means 16 is connected in electrical communication with the control system 8.

On the other hand, a driving motor 4 is provided on the rear side of the housing 5, and the driving pulley 17 of the driving motor 4 is connected to the driven pulley 11 through the belt 12. Therefore, the rotating body 6 rotates as the driven pulley 11 rotates by the operation of the drive motor 4.

The front side of the housing 5 is open, and in the lower part of the open side, the guide member 3 for guiding the flame retardant falling from the receiving groove 7 to the crucible 23 as the rotating body 6 rotates. Is provided. The guide member 3 is preferably installed at a predetermined inclination angle.

Reference numeral 2 is a protective cover for protecting the equipment mounted on the protective box for the control system from the outside, the storage hopper (1) and the guide member (3) is exposed to the outside of the protective cover (2) Is installed.

Hereinafter, the operation of the fuel aid input device according to the present invention will be described.

Crucibles of refractory material 23 on the crucible seat 24 of the sample basis weight 25 to analyze components such as carbon (C) or sulfur (S) contained in a specimen such as steel through a gas analyzer. )). Data on whether or not the crucible 23 is seated is provided to the control system 8 by the sensor 21. Thereafter, the control system 8 transmits an electrical signal to the drive motor 4 so that the drive motor 4 is driven.

As the driven pulley 11 connected to the driving pulley 17 rotates through the belt 12, the rotating body 6 rotates, and the retarder stored in the storage hopper 1 is rotated. Housed in the receiving groove (7). And the flame retardant accommodated in the accommodating groove 7 falls to the crucible 23 along the guide member 3 provided in the opening side of the housing 5.

Since the accommodating volume of the accommodating groove 7 is constant, the amount of drop of the supporting agent falling into the crucible 23 is increased as the amount of rotation of the rotating body 5 increases. The amount of rotation of the rotating body 5 is sensed by the sensor 15 of the sensing means 16 for detecting the plate 14 provided on the driven pulley 11.

As described above, the crucible 23 into which a predetermined amount of the supporting agent is introduced is transferred to the combustion section of the gas analyzer. Thereafter, the specimen is put in the crucible and the specimen is combusted by a high frequency method to analyze the gas component of the combustion product.

According to the present invention, the unit operation of all devices from the crucible mounting to the addition of the supporting medium is performed automatically, maximizing the efficiency of the operation, and improving the reliability of the analytical data on the gas component by making the input amount of the adding supporting medium constant. You can.
