Description

Technical Field

[0001] The utility model relates to the technical field of lime sampling, in particular to a lime quantitative sampling device. Background Art

[0002] The main role of white ash in steelmaking is desulfurization and dephosphorization without damaging the furnace lining. White ash has strong desulfurization and dephosphorization capabilities, which can effectively remove these impurities during the steelmaking process and improve the quality of steel. It also has the function of regulating furnace temperature and promoting slag formation. Due to the poor stability of white ash, it is very easy to react with water and carbon dioxide in the air. In order to maintain the stability of the white ash properties, at present, white ash is generally stored in a tank. The tank can keep the white ash dry and effectively reduce the contact of white ash with water and carbon dioxide in the air. However, in order to ensure the normal progress of steelmaking, before using the white ash, it is necessary to sample the white ash inside it to observe whether the white ash in the tank has reacted. At present, when sampling the white ash in the tank, it is generally only possible to sample through the feed port or the discharge port. Due to the lack of samples of white ash in the middle of the tank, the white ash samples observed in this way are less representative and it is difficult to reflect the quality of the white ash in the entire tank, which brings great inconvenience to the sampling and testing of white ash.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-4 As shown, the quantitative sampling device for lime in this embodiment includes a storage tank 1, wherein the upper and lower ends of the storage tank 1 are respectively provided with a feed port 2 and a discharge port 3, and a plurality of samplers are evenly distributed on the side wall of the storage tank 1;

[0021] The sampler includes an upper shell 4 and a lower shell 5 extending along the side wall of the storage tank 1 to the interior of the storage tank 1. A rotatable sampling roller 6 is provided in the chamber of the upper shell 4. The outer wall of the sampling roller 6 is fitted with the inner wall of the upper shell 4. A number of sampling grooves 6a are evenly distributed in the transverse direction on the sampling roller 6. The upper and lower ends of the upper shell 4 are respectively provided with a feed hole 4a and a discharge hole 4b at the positions corresponding to the sampling grooves 6a. The upper shell 4 and the lower shell 5 are connected through the discharge hole 4b. A sampling box 7 is inserted in the chamber of the lower shell 5. The sampling box 7 is provided with a sampling cavity 7a at the position corresponding to each discharge hole 4b. The sampling box 7 can be drawn out to the outside of the storage tank 1 along the lower shell 5;

[0022] The diameter of the feed hole 4a is the same as that of the sampling slot 6a, the diameter of the discharge hole 4b is larger than that of the sampling slot 6a, and the diameter of the sampling cavity 7a is larger than that of the discharge hole 4b.

[0023] The sampling roller 6 is rotatably mounted in the chamber of the upper shell 4 via a roller shaft 6b. The roller shaft 6b at one end of the sampling roller 6 extends outward from the storage tank 1. The roller shaft 6b extending outward from the sampling roller 6 is connected to a driving device.

[0024] The driving device is a motor 8 , the rotating shaft of the motor 8 is connected to the roller shaft of the sampling roller 6 , and the motor 8 is connected to the side wall of the storage tank 1 through a mounting plate 9 .

[0025] The sampling box 7 is provided with a pull-out handle 10 at one end located outside the storage tank 1 .

[0026] The upper shell 4 is a cylindrical structure, and the lower shell 5 is a rectangular structure with a recess at the upper end. The recessed part on the top of the lower shell 5 is fixedly connected to the bottom of the upper shell 4, and the discharge hole 4b at the lower end of the upper shell 4 is connected to the sampling cavity 7a on the sampling box 7.

[0027] The storage tank 1 is provided with an openable and closable cover plate 11 at the position of the feed port 2 at its upper end.

[0028] The storage tank 1 is provided with a discharge valve 12 at the discharge port 3 at the lower end thereof.

[0029] The working principle of the present invention is as follows: the ash enters the interior of the storage tank 1 along the feed port 2 for storage, and the ash covers the outside of each sampler. At this time, the sampling groove 6a on the sampling roller 6 is located in the chamber of the upper shell 4 and does not overlap with the feed hole 4a on the top of the upper shell 4. When sampling is needed, the motor 8 controls the sampling roller 6 to rotate and controls the sampling groove 6a on the sampling roller 6 to communicate with the feed hole 4a on the upper shell 4. At this time, the ash sample enters the interior of the sampling groove 6a along the feed hole 4a and is stored. Subsequently, the motor 8 of the sampler is controlled to rotate, so that it drives the sampling roller 6 to rotate. As the sampling roller 6 rotates, the ash in the sampling groove 6a will The ash enters the chamber of the upper shell 4, and the sampling roller 6 fits against the inner wall of the upper shell 4 so that the ash will not spill. When the sampling slot 6a rotates to the discharge hole 4b at the lower end of the upper shell 4 and is aligned with it, the ash in the sampling slot 6a falls along the discharge hole 4b at the bottom of the upper shell 4, and the fallen ash enters the sampling cavity 7a of the sampling box 7 in the lower shell 5. Then, the sampling box is pulled out from the lower shell 5, and the ash sample in the storage tank 1 can be taken out. When the sampling operation needs to be repeated, it is only necessary to control the motor 8 again to drive the sampling roller 6 to rotate. When the sampling slot 6a on the sampling roller 6 coincides with the feed hole 4a above the upper shell 4, the ash will re-enter the sampling slot 6a.
