Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to an activity detection device for modified and passivated metallurgical powders. Background Art

[0002] After metallurgical powders (such as calcium oxide powder, zinc oxide powder, magnesium oxide powder, aluminum oxide powder, etc.) are passivated by modifier coating, their activity (referring to the flexibility of the metal being replaced) will decrease, and the particle size will be more regular and uniform than before treatment, which is conducive to dispersion before metallurgical use. During the metallurgical process, the modifier decomposes due to heat, thereby releasing the activity of the metallurgical powder and reacting, which can improve the quality of metal smelting.

[0003] Currently, the activity of modified metallurgical powders is detected by mixing them with a working liquid (such as water, acidic solution, or alkaline solution) to form a mixed liquid, and then detecting the temperature of the mixed liquid using a thermocouple to observe how the temperature changes over time. However, when the detection is performed by placing the mixed liquid in a cup and clamping the thermocouple with a bracket, the operation is not convenient enough. In addition, the temperature detection accuracy will be affected by differences in the degree of mixing of the mixed liquid and changes in the indoor temperature, which can easily lead to detection errors.

[0004] Therefore, an activity detection device for modified and passivated metallurgical powder is proposed, which has higher temperature detection accuracy and more accurate activity detection. Utility Model Content

[0008] Furthermore, a support frame is fixedly installed on the inner side of the isolation box, and the support frame has two second through holes, one of which is plugged into the thermocouple, and the other is plugged into the transmission rod. The connecting rod is located above the support frame.

[0009] Furthermore, an annular scraper is fixedly installed inside each of the second through holes, and the thermocouple and the transmission rod pass through the corresponding annular scraper respectively.

The plug plate is plugged into the inner side of the guide box. The elastic member is fixedly installed between the end of the plug plate away from the transmission rod and the guide box.

[0011] Furthermore, an arcuate groove is formed at the end of the inserting plate close to the transmission rod, and the arcuate groove is plugged and assembled with the annular positioning groove.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1 、 Figure 2 and Figure 3 The utility model provides an activity detection device for metallurgical powder after modification and passivation, including an isolation box 1, which is hinged with a perspective door 3. After closing the perspective door 3, the isolation box 1 can isolate the internal environment to avoid interference from the external environment; a serving cup 12 is placed inside the isolation box 1, and a first through hole is opened on the top of the isolation box 1. A transmission rod 11 is inserted into the first through hole, and a stirring blade 13 is fixedly installed at the lower end of the circumferential side of the transmission rod 11. The stirring blade 13 can be rotated or raised and lowered by the transmission rod 11.

[0024] The transmission rod 11 is rotatably equipped with one end of the connecting rod 10, and the other end of the connecting rod 10 is fixedly installed with a thermocouple 6. The lower ends of the thermocouple 6 and the stirring blade 13 extend into the inner side of the cup 12 during detection. The connecting rod 10 is used to connect the thermocouple 6 so that the thermocouple 6 can move up and down with the transmission rod 11; the transmission rod 11 is provided with two annular positioning grooves 9 along the axial direction, and a positioning component 7 is provided on the top of the isolation box 1. The positioning component 7 is plugged into and assembled with one of the annular positioning grooves 9, so that the transmission rod 11 can be positioned in the upper position or the lower position. When the transmission rod 11 is in the upper position, the detection end of the thermocouple 6 and the stirring blade 13 are located above the cup 12, and when the transmission rod 11 is in the lower position, the detection end of the thermocouple 6 and the stirring blade 13 are located inside the cup 12.

[0025] Specifically, a support frame 5 is fixedly installed on the inner side of the isolation box 1, and the support frame 5 is provided with two second through holes, one second through hole is plugged into and assembled with the thermocouple 6, and the other second through hole is plugged into and assembled with the transmission rod 11, and the connecting rod 10 is located above the support frame 5; the support frame 5 plays a guiding and straightening role to prevent the thermocouple 6 and the transmission rod 11 from shaking when they move up and down, and also to prevent the thermocouple 6 from moving circumferentially through the connecting rod 10 when the transmission rod 11 rotates.

[0026] Annular scrapers 14 are fixedly installed inside the second through holes, and the thermocouple 6 and the transmission rod 11 pass through the corresponding annular scrapers 14 respectively; the annular scrapers are made of engineering plastic and serve to scrape away debris, preventing the mixed liquid from adhering to the thermocouple 6 and the transmission rod 11, which is convenient for cleaning.

[0027] Specifically, such as Figure 2 As shown, the positioning assembly 7 includes an insert plate 72, a guide box 73 and an elastic member 74. The guide box 73 is fixedly assembled with the isolation box 1. The insert plate 72 is inserted into the inner side of the guide box 73. An elastic member 74 is fixedly installed between the end of the insert plate 72 away from the transmission rod 11 and the guide box 73; the elastic member 74 is preferably a V-shaped spring piece, so that the insert plate 72 can be inserted and moved in the guide box 73, and has the force to pop out and reset.

[0028] An arc groove 71 is provided at the end of the plug plate 72 close to the transmission rod 11, and the arc groove 71 is plugged into and assembled with the annular positioning groove 9; the arc groove 71 matches the shape of the annular positioning groove 9, and the edge of the arc groove 71 is also chamfered to ensure the smoothness of the switching of the plug-in action and the firmness during plug-in.

[0029] A hand wheel 8 is fixedly mounted on the upper end of the transmission rod 11 , and the transmission rod 11 can be conveniently raised, lowered, and rotated by the hand wheel 8 , thereby improving the convenience of operation.

[0030] A temperature data acquisition box 4 is fixedly installed on the upper side of the isolation box 1. The temperature data acquisition box 4 is electrically connected to the thermocouple 6. The temperature data acquisition box 4 is an existing instrument. The temperature information collected by the thermocouple 6 can be processed through the temperature data acquisition box 4 and transmitted to an external computer for analysis and intuitive display.

[0031] A holding table 2 is fixedly installed at the inner bottom of the isolation box 1. The holding table 2 is used to place the holding cup 12. The material of the holding table 2 is ceramic, which ensures that the temperature loss rate of the contact surface is close to the environment inside the box, avoiding excessive temperature loss or accumulation, thereby affecting the temperature collection accuracy of the mixed liquid.

[0032] The working principle of this embodiment is as follows:

[0033] The thermocouple 6 and the stirring blade 13 are located at the initial position of the upper station;

[0034] When in use, the modified metallurgical powder and the working liquid are poured into the cup 12 to form a mixed liquid, the cup 12 is placed at the center of the holding table 2, and the perspective door 3 is closed;

[0035] Pressing the hand wheel 8 downwards can separate the positioning assembly 7 from the lower annular positioning groove 9 and re-engage it with the upper annular positioning groove 9, thereby moving the thermocouple 6 and the stirring blade 13 downwards into the cup 12. At this time, turning the hand wheel 8 can rotate the stirring blade 13 to stir the mixed liquid, so that the modified metallurgical powder is fully in contact with the working liquid;

[0036] Utilizing the principle that the reaction between metallurgical powder and working liquid releases heat, the thermocouple 6 will collect the temperature changes in the mixed liquid, and the data will be directly displayed by the temperature data acquisition box 4. After recording, a temperature curve chart of the change over time is hand-drawn or the data is transferred to a computer and a temperature curve chart of the change over time is drawn through the onboard software, thereby judging the activity of the modified metallurgical powder. A large temperature increase indicates that the passivation effect of the modifier coating is poor and the metallurgical powder has high activity; conversely, a small temperature change indicates that the passivation effect of the modifier coating is good and the metallurgical powder has low activity.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
