Technical Field

[0001] The invention relates to the technical field related to hot furnace real-time sampling, and in particular to a hot furnace real-time sampling mechanism and method. Background Art

[0002] The hot furnace real-time sampling equipment is a professional device used for material sampling in a high-temperature hot furnace environment. It is mainly composed of a material pump, a material pipe, a filter tank, a discharge pipe and other components. A filter device is required during the hot furnace sampling process because the material in the hot furnace may contain impurities. The filter can effectively remove these impurities and prevent impurities from entering the subsequent equipment such as the material pump to avoid damage to the equipment. At the same time, it ensures that the sampled material is pure and provides accurate and reliable samples for subsequent analysis and testing. Detector monitoring is also crucial in the real-time sampling equipment of hot furnaces. It can monitor the working status of the material pump, the filtering condition of the filter tank and the overall sealing in real time, ensure the stable and efficient sampling process, protect the safety of operators, and provide strong data support for the quality control and process optimization of hot furnace production. The real-time sampling mechanism of the hot furnace plus the filtering mechanism can effectively remove impurities in the hot furnace materials, ensure the purity of the materials entering the subsequent process, prevent impurities from damaging the material pump and other equipment, and extend the service life of the equipment. At the same time, it improves the accuracy and reliability of sampling, and provides high-quality samples for subsequent analysis and testing. It enables the real-time sampling mechanism of the hot furnace to better adapt to various complex hot furnace environments and ensure the stable sampling process.

[0003] In the current real-time sampling process of hot furnaces, a filter is basically installed on the sampling head. This may cause the sampling head to be blocked during the sampling process, and the sealing performance is poor, which makes it easy for water to enter during use. Summary of the invention

[0004] The purpose of the present invention is to provide a hot furnace real-time sampling mechanism and method, in order to overcome the existing technical background in the current hot furnace real-time sampling process, basically a sampling head is installed with a filter net, which may cause the sampling head to be blocked during the sampling process, and the sealing performance is poor, and water is easy to enter during use.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hot furnace real-time sampling mechanism and method, a hot furnace real-time sampling mechanism, comprising a material taking tank, a material taking pipe, a material taking pump and a material discharging pipe, characterized in that the upper surface of the material taking tank is connected with the material taking pipe, the one side surface of the material taking pipe is fixedly connected with the material taking pump, the one side surface of the material taking pump is connected with the material discharging pipe, the outer surface of the material taking pipe is sleeved with a filtering mechanism, the upper surface of the material taking tank is provided with a sealing mechanism, and the inner surface of the material taking tank is provided with a fixing mechanism;

The filter tank is connected through one side surface of the material taking pipe, the filter screen is provided on the inner side surface of the filter tank, the connecting cover is threadedly connected to the outer side surface of the filter tank, and a handle is installed on one side surface of the connecting cover.

[0007] Preferably, the discharge pipe passes through the material taking tank for connection.

[0008] Preferably, the sealing mechanism includes a sealing groove, a clamping block, a sealing gasket, a connecting ring, a fixed block and a limiting groove. A sealing groove is provided on the upper surface of the material taking tank, a clamping block is installed on the upper surface of the sealing groove, a sealing gasket is attached to the inner surface of the sealing groove, a connecting ring is provided on the upper surface of the sealing groove, a fixing block is installed on one side surface of the connecting ring, and a limiting groove is provided on one side surface of the fixing block.

[0009] Preferably, the inner wall size of the limiting groove matches the outer wall size of the block.

[0010] Preferably, the connecting ring is threadedly connected and fixed to the clamping block and the fixing block.

[0011] Preferably, the fixing mechanism includes a fixing frame, a placement groove, an installation groove, a spring, a mounting block, a monitor and a card slot.

[0012] Preferably, the inner spring of the mounting groove is connected to the mounting block to form a telescopic structure.

[0013] A method for a hot furnace real-time sampling mechanism, the specific steps are as follows:

[0014] S1. First, check whether all parts of the hot furnace sampling equipment are intact. The material of the sampling tube is made of high-temperature resistant alloy steel, with a length of 1.5 meters and a diameter of 3 centimeters. It can withstand a high temperature of at least 1200 degrees Celsius. The sampling container must be made of high-temperature resistant ceramic material with a capacity of 0.5 liters and good sealing to ensure that the equipment is not damaged or leaking and can work normally;

[0015] S2. Then put on high-temperature resistant heat-insulating clothing. The heat-insulating performance of the heat-insulating clothing should be able to ensure human safety in a high-temperature environment of 1000 degrees Celsius for 30 minutes. Wear high-temperature resistant gloves with a thickness of 2 cm. The goggles should be able to effectively block heat radiation and splashes to ensure the safety of operators when approaching the hot furnace;

[0016] S3. Then determine the location of the hot furnace where sampling is required. The temperature of the hot furnace is usually between 800 degrees Celsius and 1500 degrees Celsius. Ensure that the sampling equipment can accurately reach the sampling point. The optimal operating distance from the hot furnace is 1 meter.

[0017] S4. Use the feeding tube to quickly insert it into the hot furnace. The feeding tube should have good high temperature resistance and heat insulation effect. The thickness of the heat insulation material of the feeding tube is 1 cm, which can effectively block heat conduction. The insertion speed should be controlled at 5 cm per second to prevent the operator from being scalded;

[0018] S5. After the material taking tube is inserted into the appropriate position, turn on the material taking pump to allow the sample in the furnace to flow into the material taking tank. The operation should be quick and accurate to avoid external contamination of the sample.

[0019] S6. After sampling is completed, quickly pull the sampling tube out of the hot furnace;

[0020] S7. Place the removed samples in a safe place for subsequent processing. At the same time, clean and maintain the sampling equipment to prepare for the next use.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. After starting the material pump, place the material pipe in the hot furnace, which can quickly and efficiently extract materials from the hot furnace for testing and analysis, so as to adjust the process parameters in time and improve production efficiency and product quality. Secondly, the material is filtered through the filter before entering the material pump, which effectively removes impurities and large particles in the material, prevents these impurities from damaging the material pump and subsequent equipment, and extends the service life of the equipment. At the same time, it also ensures that the material taken out of the hot furnace has a high purity, providing a reliable sample for subsequent analysis and testing. When the filter is full, the connection cover can be opened by the handle, the filter can be easily cleaned, and then reinstalled for continued use. This design makes the maintenance of the sampling mechanism simple and convenient, without the need for complicated disassembly process, which greatly improves the maintainability and use efficiency of the equipment;

[0023] 2. Place the sealing gasket in the sealing groove and fix it, which can effectively enhance the sealing of the connection and prevent the high-temperature material in the hot furnace from leaking during the sampling process, avoiding the potential safety hazards caused by the leakage of high-temperature materials, and also ensuring the accuracy and reliability of sampling. Then, the connecting ring drives the fixing block to be placed in the sealing groove and rotate. When the limit groove is stuck with the block, it is fixed by bolts. This connection method is simple and convenient to operate, and can quickly realize the installation and fixation of the sealed connection. In actual use, it not only improves the installation efficiency, but also has a firm and reliable connection, which can withstand the high temperature and pressure environment in the hot furnace and ensure the stability of the sampling process.

[0024] 3. The design of pressing the mounting block to squeeze the spring into the mounting slot is simple and quick to operate. When installing the monitor, no complicated tools and cumbersome steps are required, which greatly improves the installation efficiency. When the mounting block is completely inserted into the mounting slot, the monitor is placed in the placement slot. This method makes the installation position of the monitor more accurate and stable. Once the position of the card slot and the mounting slot coincide, the spring will push the mounting block into the card slot to complete the fixation of the fixing frame and the monitor. This fixing method is firm and reliable, and can ensure that the monitor will not loosen or fall off due to vibration or other factors during the real-time sampling of the hot furnace. The monitor plays a vital role in the hot furnace sampling process. It plays an important role. On the one hand, it can monitor the working status of the material pump in real time, such as pressure, flow and other parameters, to ensure the normal operation of the material pump and avoid affecting the sampling work due to failure of the material pump. On the other hand, the monitor can monitor the filtering condition of the filter tank. When the filter is blocked or the filtering effect is reduced, it will issue an alarm in time to remind the operator to clean or replace the filter to ensure the quality and efficiency of sampling. The monitor can also monitor the overall sealing of the real-time sampling mechanism of the hot furnace. Once a problem with the sealing is found, timely measures can be taken to prevent the leakage of high-temperature materials in the hot furnace, thereby ensuring the safety of the operator and the smooth progress of the sampling work.
