Description

Technical Field

[0001] The utility model relates to the technical field of furnace charge detection equipment, in particular to a blast furnace push rod protection device. Background Art

[0002] Currently, compressive strength testing of blast furnace charge is mostly performed at room temperature, with high-temperature strength testing less common. However, as a high-temperature reactor, the high-temperature strength of the charge can more accurately reflect the charge's true state within the blast furnace. Currently, few manufacturers of high-temperature thermal strength testing equipment for charge materials exist, and these devices are still in the process of being promoted and improved. Problems remain, such as limited sample capacity, high-temperature push rods prone to breakage due to rising temperatures during the automatic sample pushing process, and a short service life, severely impacting the quality and efficiency of experimental research. Utility Model Content

[0003] The purpose of the utility model is to provide a blast furnace push rod protection device, which reduces the force on the push rod during the sample delivery process when the push rod carries the sample deep into the high-temperature furnace to test the strength, facilitates the sample to reach the testing point, and improves the service life of the push rod.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A blast furnace push rod protection device comprises a slide rail and a slider. The slider is provided with a groove, the groove matches and is inserted into one end of the push rod, and the slider is slidably connected to the slide rail.

[0006] In a further solution, the groove is waist-shaped, a male buckle is provided on one end of the groove close to the push rod, and a female buckle is provided on one end of the push rod close to the groove, and the male buckle and the female buckle are matched and buckled.

[0007] In a further solution, the male buckle is a concave structure arranged at the bottom of the groove, and the female buckle is a convex structure matching the concave structure.

[0008] In a further solution, a lofting groove is provided on the upper surface of the slider.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0023] like Figure 1 As shown, a blast furnace push rod protection device includes a slide rail 1 and a slider 2. The slider 2 is provided with a groove 4, and the groove 4 matches and is inserted into one end of the push rod 5. The slider 2 is slidably connected to the slide rail 1.

[0024] Its working principle is to place the sample on the slider 2, put the slide rail 1 into the heating furnace, heat the sample to the temperature required for testing, such as 1500℃ in the furnace, align the push rod 5 with the groove 4 and insert it. The push rod 5 pushes the slider 2 to push the sample under the pressure head, and the pressure head presses down to record the compressive strength data. As the length of the push rod 5 entering the furnace body increases, at high temperatures, the front end of the push rod 5 is inserted into the groove 4, which can prevent the front end of the push rod 5 from gradually tilting downward. By increasing the structure of the slide rail 1 and the slider 2, the gravity of the sample applied to one end of the push rod 5 is reduced. By setting the groove 4 to match the push rod 5, the groove 4 supports the push rod 5, preventing the push rod 5 from extending too long and contacting and bonding with the track under the action of high temperature, thereby causing the risk of breakage.

[0025] The groove 4 is waist-shaped, and a male buckle is provided on the end of the push rod 5 near the groove 4, and a female buckle is provided on the end of the push rod 5 near the groove 4. The male buckle and the female buckle are matched and buckled. The connection between the male buckle and the female buckle can further prevent the push rod 5 from falling, and it is also convenient to retract the slider 2.

[0026] like Figure 2 As shown, the male buckle is a concave structure 41 provided at the bottom of the groove 4, and the female buckle is a convex structure 51 matching the concave structure 41. The concave structure 41 and the convex structure 51 can be directly separated from each other, making it convenient for the slider 2 to be buckled with the push rod 5.

[0027] A lofting groove 3 is provided on the upper surface of the slider 2. The design of the lofting groove 3 facilitates the fixation of the sample and prevents mutual interference between samples.

[0028] There are multiple sample slots 3. This allows multiple samples to be measured simultaneously.

[0029] The slide rail 1 is installed in the heating furnace hearth of the blast furnace, which is used to preheat the blast furnace charge sample to be tested. During actual testing, a limit groove can be set in the heating furnace hearth to fix the slide rail 1.

[0030] The push rod 5 is inserted into the groove 4 by at least 3 mm near one end of the groove 4. This allows the push rod 5 to be securely connected to the groove 4.

[0031] Push rod 5 is close to groove 4 one end and is matched with groove 4 clearance. It is convenient for push rod 5 to insert groove 4 like this, and it is also convenient for push rod 5 to take out from groove 4, thereby utilizing for the second time.

[0032] There are multiple sliders 2, and a structure for pulling each other is provided between two adjacent sliders 2. The structure for pulling each other can be a keyway structure, specifically a slider 2 with a slot and another slider 2 with keys that engage with each other.

[0033] At least two semicircular raised slideways are provided on the slide rail 1, and matching semicircular slide grooves are provided on the slider 2. This allows the slider 2 to slide more smoothly on the slide rail 1.
