Description

Technical Field

[0001] This utility model relates to the field of sintering technology, specifically to an online sampling and testing device for the strength of a sintering drum. Background Technology

[0002] In the field of sinter production and quality control, the drum strength of sinter is one of the key indicators for measuring its quality. Accurately and timely obtaining sinter samples and conducting drum strength tests is of great significance for ensuring stable sinter quality and optimizing production processes.

[0003] Most existing online sampling and testing devices for the strength of sintered ore drums use head samplers to collect subsamples from the full cross-section of the material parabolic position. Due to the differences in the strength of sintered ore, the particles of high-strength sintered ore are tightly bound together. Compared with low-strength sintered ore, the sampler needs to overcome greater resistance to separate the sample from the whole material during the sampling process.

[0004] Increased sampling resistance directly affects the sampling process, potentially leading to a reduction in the sample volume. Insufficient sample volume means that the collected sample cannot fully represent the overall quality of the sinter, thus affecting the accuracy and reliability of subsequent drum strength testing results. This makes it impossible to provide a true and effective basis for production decisions, and may ultimately affect the product quality and production efficiency of the sinter.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By storing energy through a spring and launching the ejector plate, the sampling tube is quickly inserted into the sintered ore. This ejection method can provide a large force instantly to overcome the sampling resistance caused by sintered ores of different strengths. Compared with traditional sampling methods, when facing high-strength sintered ores, it can ensure that the sampling tube is smoothly inserted into the material, effectively avoiding the problem of insufficient sampling due to high sampling resistance. It ensures that each sampling can obtain sufficient and representative samples, so that the test results can more accurately reflect the overall quality of the sintered ore.

[0018] 2. When the sample weight inside the slider is sufficient, the tension spring provides a stable elastic force for the slider's up-and-down movement, enabling the slider to overcome the pulling force and move downwards. The magnet at the opening / closing point magnetically attracts the delivery tube and opens, allowing the sample to fall into the slider. Subsequently, under the transmission action of connecting rod one and connecting rod two, the guide plate angle is adjusted, and the sample slides into the drum. The entire process requires no manual intervention, which not only improves work efficiency but also reduces labor intensity, enabling rapid and accurate delivery of samples to the drum for testing and timely acquisition of test results.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4This utility model provides a technical solution: an online sampling and testing device for the strength of a sintering drum, comprising a base plate 1, a sampling mechanism 2 slidably mounted on the top of the base plate 1, a sampling tube 3 fixedly mounted on the side of the sampling mechanism 2, the sampling mechanism 2 including a slide plate 201, an ejection plate 207 slidably mounted on the inner wall of the top of the slide plate 201, a slide rod 210 fixedly mounted on the side wall of the ejection plate 207, a top plate 212 slidably mounted on the outer wall of the slide rod 210, the bottom of the top plate 212 being fixedly connected to the top side of the slide plate 201, and a spring 211 fixedly connected to the opposite surface of the top plate 212 and the ejection plate 207, the spring 211 storing energy and ejecting the sample. The ejector plate 207 propels the sampling tube 3 to quickly insert into the sintered ore. This ejection method can provide a large force instantly, overcoming the sampling resistance caused by sintered ores of different strengths. Compared with traditional sampling methods, when facing high-strength sintered ores, ejection sampling can ensure that the sampling tube 3 can be smoothly inserted into the material, effectively avoiding the problem of insufficient sample volume caused by high sampling resistance, and ensuring that sufficient and representative samples are obtained each time. A rack 208 is fixedly installed on the side wall of the slide plate 201. A gear 203 is meshed at the bottom of the rack 208. The center of the gear 203 is fixedly installed on the drive of the motor 202. At the end, the side wall of the motor 202 is fixedly connected to the side wall of the base plate 1; a support plate 204 is fixedly installed on the side of the base plate 1 near the motor 202, a fixing tube 205 is fixedly installed on the top of the support plate 204, a stop rod 206 is rotatably installed on the outer wall of the fixing tube 205, a top locking block 213 is fixedly installed at the bottom of the end of the stop rod 206 away from the fixing tube 205, a bottom locking block 214 abuts against the bottom of the top locking block 213, and the bottom of the bottom locking block 214 is fixedly connected to the top side of the ejection plate 207. The top locking block 213 at the end of the stop rod 206 abuts against the bottom locking block 214 fixed at the top side of the ejection plate 207, thus launching the ejector. Plate 207 is stably fixed in the initial position, keeping spring 211 in a compressed state, ready for ejection sampling. This snap-fit ​​structure is simple and reliable, and can withstand the elastic force of spring 211, ensuring that ejection plate 207 will not move accidentally before sampling, thus guaranteeing the stability and reliability of ejection sampling. When slide plate 201 slides to the appropriate position, unlocking plate 215 at the end of abutment rod 206 contacts the top of top plate 212, causing abutment rod 206 to rotate around fixed tube 205. Top latch 213 separates from bottom latch 214, and the elastic force of spring 211 is released instantly, pushing ejection plate 207 to slide quickly, thus achieving ejection sampling.

[0026] Please see Figure 4This utility model provides a technical solution: an online sampling and testing device for the strength of a sintered ore drum, comprising a bottom plate 1 with a groove 101 at the top, the inner wall of the groove 101 being slidably connected to the bottom outer wall of a sampling mechanism 2, a collection port 102 on the inner wall of the groove 101 away from the sampling mechanism 2, a connecting ring 8 being threadedly connected to the bottom of the inner wall of the collection port 102, a tension spring 9 being fixedly installed at the bottom of the connecting ring 8, a slider 11 being slidably installed on the outer wall of the tension spring 9, a connecting rod 13 being rotatably installed at the bottom side of the slider 11, a guide plate 14 being rotatably installed at the bottom of the connecting rod 13, a connecting rod 12 being rotatably installed on the outer wall of the guide plate 14, the top of the connecting rod 12 being rotatably connected to the outer wall of the bottom plate 1, and the guide plate 1... A rotating drum 15 is provided on the side end. In actual operation, when the sample weight in the slider 11 is sufficient, the tension spring 9 provides a stable elastic force for the up and down movement of the slider 11. At this time, the slider 11 can overcome the tension of the tension spring 9 and move down. The magnet 10 at the opening and closing point of the slider 11 magnetically attracts and opens the conveying tube 7, allowing the sample to fall smoothly into the slider 11. Under the transmission action of the connecting rod 12 and the connecting rod 2 13, the angle of the guide plate 14 is adjusted, and the sample slides into the rotating drum 15. The whole process realizes the accurate collection and automatic conveying of the sample without manual intervention, which not only improves work efficiency but also reduces labor intensity. At the same time, the tension spring 9 also ensures that the slider 11 can rise and reset in time after the sample is discharged.

[0027] Please see Figure 2 This utility model provides a technical solution: an online sampling and testing device for the strength of a sintered ore drum, including a push plate 6 fixedly installed on the top side of a base plate 1, with the bottom edge of the push plate 6 sliding against the inner wall of a sampling tube 3. After sampling is completed, the push plate 6 can slide along the inner wall of the sampling tube 3 to clean the material remaining on the inner wall of the sampling tube 3. Subsequently, the cleaned material enters the slider 11 through the collection port 102 for collection. In this way, the sample is effectively prevented from remaining in the sampling tube 3, ensuring the independence and accuracy of each sampling.

[0028] Please see Figure 2 This utility model provides a technical solution: an online sampling and testing device for the strength of a sintered ore drum, including a slide plate 201 with an ejection groove 209 on the top, and the inner wall of the ejection groove 209 is slidably connected to the bottom of the ejection plate 207. The ejection groove 209 provides a clear track for the sliding of the ejection plate 207, so that the ejection plate 207 can always move along the predetermined path during the sliding process without deviation or shaking, thereby ensuring the accuracy and stability of the ejection sampling.

[0029] Please see Figure 1This utility model provides a technical solution: an online sampling and testing device for the strength of sintered ore drum, including a base plate 1 with a baffle 4 fixedly installed on the side wall, and a conveyor belt 5 slidably installed on the side wall of the baffle 4. The conveyor belt 5 can smoothly and stably realize continuous material transportation by means of the sliding connection with the side wall of the baffle 4, effectively ensuring the continuity of sample transfer after sintered ore sampling.

[0030] Working principle: When motor 202 is turned on, it drives gear 203 to rotate, causing slide plate 201 to slide on top of base plate 1. At this time, ejector plate 207 is in a locked state, and spring 211 is compressed and stores energy. As slide plate 201 continues to slide, unlocking plate 215 at the end of stop rod 206 contacts the top of top plate 212, causing stop rod 206 to rotate. Top locking block 213 separates from bottom locking block 214, and the elastic force of spring 211 pushes ejector plate 207 to slide rapidly. Ejector plate 207 drives sampling tube 3 to insert into sintered mineral material to complete sampling. After sampling is completed, motor 202 reverses, causing slide plate 201 to reset. During the reset process, sampling tube 3 moves backward. The material contacts the bottom edge of the push plate 6, which is fixedly installed on the top side of the base plate 1. As the sampling tube 3 continues to move backward, the push plate 6 gradually pushes out the material remaining on the inner wall of the sampling tube 3 and enters the slider 11 through the collection port 102 and the conveying pipe 7. When the weight of the sample in the slider 11 is sufficient, the slider 11 moves downward against the tension of the tension spring 9. The magnet 10 at the opening and closing point of the slider 11 magnetically attracts the conveying pipe 7 and opens. When it opens, the weight of the slider 11 decreases, so the slider 11 will be pulled up by the tension spring 9. The angle of the guide plate 14 is adjusted by the action of the connecting rod 12 and the connecting rod 2 13. At this time, the sample falls onto the guide plate 14 through the discharge pipe 16 and slides into the drum 15.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
