Description

Technical Field

[0001] This utility model belongs to the field of experimental instrument technology, and specifically relates to a protective device for the determination of divalent iron in iron ore. Background Technology

[0002] In the field of iron ore phase analysis, the determination of iron content in magnetic iron is a challenging and complex process. In particular, when determining the magnetite content in magnetic iron, the total iron content, ferrous iron content, and ferric iron content need to be tested separately. Since ferrous iron is highly reactive and easily oxidized in air, taking effective protective measures to prevent its oxidation during the determination of ferrous iron content is a key step in ensuring the accuracy of the test results. Therefore, protective devices are required.

[0003] For example, Chinese patent CN218036799U discloses a protective device for determining divalent iron in iron ore; the bottom of the grid stand is provided with a grid stand lifting mechanism, and triangular flasks are installed in the grid of the grid stand, wherein the neck of the triangular flask fits into the corresponding grid, and the mouth of the triangular flask is equipped with a rubber stopper. The beaker is fixed on a safety fixed base, and each triangular flask is connected to the inside of the beaker through a pipe, and the pipe is supported by a rubber tube bracket.

[0004] Although the aforementioned patent can effectively protect ferrous iron from oxidation during the dissolution process, the device still has some defects that need to be improved. Specifically, fixing the triangular flask solely through the grid of the grid stand may not be stable enough in actual operation, causing the flask to be placed unevenly and interfering with the experimental process. Furthermore, the heat conduction effect of the electric heating plate at the bottom contacting the flask is not good enough, affecting the dissolution efficiency and effect of the sample.

A heating component is disposed inside the first groove. A flask is placed inside the first groove on one side of the heating component. An adjusting component is fixedly connected to one side of the flask on the base. A grid plate is slidably connected to the base above the flask via the adjusting component. A positioning component is disposed on one side of the grid plate. A rubber bracket is fixedly connected to the middle of the top of the base. A second groove is formed on the left side of the top of the base. A beaker is placed inside the second groove. A rubber stopper is inserted into the upper side of the flask. A rubber tube is fixedly connected to the top of the rubber stopper. A glass tube is fixedly connected to the top of the beaker.

A heat-conducting column is fixedly connected to the inner side of the electric heating plate. A fitting groove is formed on the outer side of the heat-conducting pad, and the heat-conducting column is fitted and connected to the fitting groove.

[0009] As a preferred technical solution, an oxygen sensor is fixedly connected to one side of the rubber stopper, and the oxygen sensor is offset from one side of the rubber tube.

[0010] As a preferred technical solution, the positioning component includes a slide groove, which is formed inside the grid plate. A slider is slidably connected inside the slide groove, and a spring is fixedly connected between the slider and the slide groove. A positioning block is fixedly connected to the side of the slider away from the spring, and one side of the positioning block is in contact with one side of the flask.

[0011] As a preferred technical solution, guide grooves are provided on both sides of the inner side of the slide groove, and guide blocks are slidably connected inside the guide grooves. One side of the guide block is fixedly connected to one side of the slider.

[0013] In summary, the present invention has the following main advantages:

[0014] First, this utility model, by opening a first groove on the base, inserts the bottom of the flask into the first groove, and then drives the grid plate to move through the adjusting component, so that the positioning component in the through hole of the grid plate contacts the flask.

[0025] refer to Figure 3 and Figure 6 The heating assembly 3 includes an electric heating plate 31, which is fixedly connected inside the first groove 2. A heat-conducting pad 33, made of highly thermally conductive metal or graphite, is attached to the inner side of the electric heating plate 31 for better heat conduction. One side of the flask 4 is inserted into the heat-conducting pad 33. A heat-conducting column 32 is fixedly connected to the inner side of the electric heating plate 31. A fitting groove 34 is provided on the outer side of the heat-conducting pad 33, and the heat-conducting column 32 is fitted to the fitting groove 34. By setting the heating assembly 3, the electric heating plate 31 is fixed in the first groove 2 to provide heat. The heat-conducting column 32 fits into the fitting groove 34 of the heat-conducting pad 33, efficiently transferring heat to the heat-conducting pad 33 and increasing the heating area. The flask 4 is inserted into the heat-conducting pad 33, making full contact with the heat-conducting pad 33, so that heat is conducted to the flask 4, which can accelerate the dissolution process and improve the dissolution effect.

[0026] refer to Figure 1 An oxygen sensor 10 is fixedly connected to one side of the rubber stopper 5, and the oxygen sensor 10 is offset from one side of the rubber tube 6. By setting the oxygen sensor 10, the oxygen concentration in the flask 4 can be monitored in real time. During the determination of ferrous iron, it can be detected in time whether there are problems such as poor sealing of the device that cause air to enter. Once the oxygen concentration is abnormal, measures can be taken immediately to ensure that ferrous iron is always in an oxygen-free environment and prevent it from being oxidized.

[0027] refer to Figure 4 The positioning component 12 includes a slide groove 123, which is formed inside the grid plate 11. A slider 122 is slidably connected inside the slide groove 123. A spring 124 is fixedly connected between the slider 122 and the slide groove 123. A positioning block 121 is fixedly connected to the side of the slider 122 away from the spring 124. The positioning block 121 has an arc-shaped structure, and one side of the positioning block 121 movably abuts against one side of the flask 4. Guide grooves 125 are formed on both sides inside the slide groove 123, and guide blocks 126 are slidably connected inside the guide grooves 125. One side of the guide block 126 is fixedly connected to one side of the slider 122. By setting the positioning component 12, when the grid plate 11 moves downward, the positioning block 121 slides downward along the upper side of the flask 4. The positioning block 121 pushes the slider 122 to move, and the slider 122 pushes the spring 124 to move until the positioning block 121 stops moving. At this time, under the action of the spring 124, the positioning block 121 clamps the flask 4, which can fix the flask 4 to prevent shaking and reduce the risk of experimental failure due to the instability of the flask 4. The guide groove 125 cooperates with the guide block 126 to ensure that the slider 122 slides stably and avoids deviation.

[0028] refer to Figure 5 The adjustment assembly 13 includes a fixing frame 136, which is fixedly connected to the base 1 on the side near the grid plate 11. A motor 131 is fixedly connected to one of the top ends of the fixing frame 136. A first gear 132 is fixedly connected to the output end of the motor 131. A second gear 133 is meshed with one side of the first gear 132. A lead screw 134 is fixedly connected to one side of the second gear 133. A screw block 135 is threaded onto the outer surface of the lead screw 134. The screw block 135 is slidably connected inside the fixing frame 136. One side of the screw block 135 is fixed to one side of the grid plate 11. Connection; by setting the adjustment component 13, the motor 131 drives the first gear 132 to rotate, the first gear 132 meshes with the second gear 133, thereby driving the lead screw 134 connected to the second gear 133 to rotate. When the lead screw 134 rotates, the screw block 135 slides along the axial direction of the lead screw 134 in the fixed frame 136, driving the grid plate 11 to move, flexibly adjusting the relative position of the positioning component 12 and the flask 4, making it convenient to place and remove the flask 4, and making the positioning component 12 tightly fix the flask 4. It should be noted that the first gear 132 is a small gear and the second gear 133 is a large gear, making the movement of the grid plate 11 more stable and powerful.

[0029] Operating principle and advantages: Place the heat-conducting pad 33 onto the electric heating plate 31 in the first groove 2, ensuring that the heat-conducting column 32 is tightly fitted to the fitting groove 34. Insert one side of the flask 4 into the heat-conducting pad 33, so that the flask 4 is stably placed in the first groove 2. Place the beaker 8 stably in the second groove 9 at the top of the base 1. Insert the rubber stopper 5 into the upper side of the flask 4, ensuring a good seal. Connect one end of the rubber tube 6 to the top of the rubber stopper 5. Pass the other end of the rubber tube 6 through the rubber bracket 14 and connect it to one side of the glass tube 7 at the top of the beaker 8, forming a gas passage between the flask 4 and the beaker 8. The rubber tube 6 does not contact the heating component 3. Then, the motor 131 drives the first gear 132 to rotate. Since the first gear 132 meshes with the second gear 133, the second gear 133 rotates accordingly, thereby driving the lead screw 134 to rotate. When the lead screw 134 rotates, the screw block 135 slides along the axial direction of the lead screw 134 in the fixing frame 136. 35 is fixedly connected to one side of the grid plate 11, thereby driving the grid plate 11 to move downward and gradually approach the flask 4. As the grid plate 11 moves downward, the positioning block 121 begins to slide downward along the upper inclined surface of the flask 4. The positioning block 121 pushes the slider 122 to move in the slide groove 123. The slider 122 compresses the spring 124, while the guide block 126 slides in the guide groove 125 to ensure the stable movement of the slider 122. When the positioning block 121 moves to the appropriate position, under the elastic force of the spring 124, the positioning block 121 tightly clamps the flask 4, fixing the flask 4 in the first groove 2 to prevent the flask 4 from shaking. The electric heating plate 31 is powered on and begins to heat up, transferring heat to the heat-conducting pad 33. The heat is quickly conducted to the flask 4, accelerating the dissolution process of ferrous iron-related substances in the flask 4, improving the dissolution effect, and enhancing the stability and safety of the experimental operation, providing a reliable guarantee for the determination of ferrous iron.
