Description

Technical Field

[0001] The present invention relates to the technical field of coke sampling equipment, and more particularly to a detection sampling equipment suitable for blast furnace top-loading for refining metallurgical coke. Background Art

[0002] Coke is an important charge that provides heat and reducing agents for blast furnace smelting. According to smelting requirements, blast furnace coke must have appropriate chemical and physical properties, including thermal properties at high temperatures. Since the successful use of coke in blast furnace ironmaking in the early 18th century, it has a history of more than 200 years. In order to meet the requirements of blast furnace operation, a large amount of research has been conducted on the properties of coke over a long period of time, and sampling has been carried out to test the chemical composition, cold state and hot state indicators of coke.

[0003] For example, utility model patent CN212391229U discloses a blast furnace coke sampling machine, which is a motor that rotates a driving roller at the lower end, and a track is embedded around the outer side of the driving roller, and the upper end of the track is connected to a slide rail. After the sampling frame samples the coke, the coke enters the interior of the device body and falls to the upper end of the screening net. The motor drives the connecting rod to rotate at the upper end of the screening net through the driving roller, and the connecting rod drives the support frame to crush the coke. The crushing wheel inside the support frame can further crush the coke, so that the sampler can automatically crush the coke after sampling the coke, which is convenient for subsequent coke detection.

[0004] However, the above-mentioned patent document only has the function of direct sampling. In actual use, there is no structure that can stabilize the sample. That is, when the sampling slot tube is extended into the sampling, it is impossible to ensure that the state of the sample taken out remains stable. When the sampling slot tube is extended, the sample will roll and become chaotic due to the inertia of the sample and the squeezing interference of other external samples. The actual position state of the coke sample in the blast furnace cannot be accurately obtained, which greatly affects the actual sampling result of the coke sample. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a detection and sampling device suitable for blast furnace top-loading metallurgical coke refining to solve the problems raised in the above-mentioned background technology.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0026] The existing technology does not have a structure that can stabilize the sample. That is, when the sampling slot tube is inserted for sampling, it is impossible to ensure that the state of the sample taken out remains stable. When the sampling slot tube is extended, the sample will roll and become chaotic due to the inertia of the sample and the squeezing interference of other external samples. The actual position state of the coke sample in the blast furnace cannot be accurately obtained, which greatly affects the actual sampling result of the coke sample. To solve this problem, the following technical solution is proposed:

[0027] Refer to the instruction manual Figure 1-Figure 7 , a detection and sampling equipment suitable for blast furnace top charging and refining metallurgical coke, such as Figure 1 and Figure 2 As shown, it includes a sampling frame 1, a sampling slot tube 2 is fixedly installed on one side of the sampling frame 1, and a capping mechanism 3 and a blocking mechanism 4 are provided on the top of the sampling slot tube 2;

[0029] like Figure 3 and Figure 4 As shown, one side outer wall of the capping plate 32 passes through the outer wall of the sampling slot tube 2, and a rotating gear 33 is fixedly installed on one side outer wall of the capping plate 32. The rotating gear 33 is rotatably installed on the inner wall of the sampling frame 1. The rotating gear 33 is arranged in a vertical state. The rotation of the rotating gear 33 drives the capping plate 32 to rotate synchronously on the inner wall of the sampling slot tube 2.

[0030] like Figure 3 and Figure 4 As shown, a toothed plate 34 is engaged with the top of the rotating gear 33. The toothed plate 34 is slidably mounted on the outer wall of the sampling rack 1. The toothed plate 34 is arranged in a horizontal state. The toothed plate 34 moves horizontally to push the rotating gear 33 to rotate.

[0031] like Figure 3 and Figure 4As shown, a toggle ring 35 is fixedly mounted on the outer wall of one side of the pushing tooth plate 34. The toggle ring 35 and the pushing tooth plate 34 are arranged perpendicular to each other, and the toggle ring 35 is arranged in a vertical state. The inner wall of the toggle ring 35 is threadedly connected to a threaded rod 36, and the threaded rod 36 is arranged in a horizontal state. A motor 37 is provided on one side of the threaded rod 36. The motor 37 is fixedly mounted on the top outer wall of the sampling frame 1, and the motor 37 is arranged in a horizontal state. The motor 37 drives the threaded rod 36 to rotate so that the toggle ring 35 moves horizontally, that is, the toggle ring 35 drives the pushing tooth plate 34 to move synchronously.

[0032] like Figure 5 and Figure 6 As shown, the blocking mechanism 4 includes a plurality of retaining plates 41 fixedly mounted on the inner wall of the sampling slot tube 2. The plurality of retaining plates 41 are arranged in a vertical state and are arranged in a horizontally equidistant manner.

[0033] like Figure 5 and Figure 6 As shown, a plurality of traverse rods 42 are fixedly mounted on the top of the plurality of retaining plates 41 , respectively. The plurality of traverse rods 42 are arranged in a vertical state and are arranged in a horizontally equidistant manner. The traverse rods 42 are synchronously driven by the retaining plates 41 .

[0034] like Figure 6 and Figure 7 As shown, a spiral groove 43 is provided on the outer wall of the bottom of the multiple rotating support rods 42, and a partition 44 is threadedly connected to the outer wall of the spiral groove 43. The partition 44 is arranged in a vertical state, and the multiple partitions 44 are arranged parallel to each other. The multiple partitions 44 and the inner wall of the sampling slot tube 2 are arranged corresponding to each other. A pressure plate 45 is fixedly installed on the top of the multiple partitions 44, and the multiple pressure plates 45 are arranged in an arc shape. When the multiple pressure plates 45 are compressed, they drive the partitions 44 to move downward synchronously, and then the partitions 44 are driven to perform horizontal angle displacement through the spiral groove 43 provided on the outer wall of the rotating support rod 42, that is, the multiple partitions 44 rotate synchronously to form a vertical plate blocking the sampling slot tube 2.

[0035] like Figure 6 and Figure 7 As shown, support springs 46 are fixedly installed on the inner walls of multiple partitions 44.

The downward movement of the partitions 44 can compress the support springs 46.

[0036] During specific implementation, the sampling slot tube 2 is extended into the blast furnace for sampling, and the coke sample enters the middle sampling slot tube 2 and is blocked by the bottom plate 31. The motor 37 is then started to drive the threaded rod 36 to rotate so that the toggle ring 35 moves horizontally, that is, the toggle ring 35 drives the pushing tooth plate 34 to move synchronously, and the pushing tooth plate 34 moves horizontally to drive the rotating gear 33 to rotate. The rotating gear 33 rotates and drives the capping plate 32 to rotate synchronously on the inner wall of the sampling slot tube 2, that is, the capping plate 32 extends from one side to cover the top position of the sampling slot tube 2, and the top of the sampling slot tube 2 is sealed to prevent the coke sample from being squeezed and interfered by other external samples during the process of being brought back.

[0037] At the same time, during the rotation of the capping plate 32, the capping plate 32 squeezes the tops of the multiple pressure plates 45, that is, when the multiple pressure plates 45 are compressed, they drive the partitions 44 to move downward synchronously and compress the support springs 46, and then the partitions 44 are driven to perform horizontal angle displacement through the spiral grooves 43 opened on the outer wall of the rotating support rod 42, that is, the multiple partitions 44 rotate synchronously and form a vertical plate barrier on the sampling slot tube 2, so that the coke sample can be enclosed at a fixed distance to avoid the coke sample from rolling and becoming chaotic due to inertia when being brought back.

[0038] In summary, a rotating capping plate is provided on the top of the sampling trough tube to seal the top of the sampling trough tube, thereby preventing the coke sample from being squeezed and disturbed by other external samples during the process of being brought back. At the same time, multiple partitions pushed by pressure rotate synchronously to form a barrier structure between the coke samples, so that the coke samples can be sealed at a fixed distance, thereby preventing the coke sample from rolling and becoming chaotic due to inertia when being brought back.
