Description

Technical Field

[0001] The utility model relates to the technical field of material storage equipment, in particular to a lime block storage device. Background Art

[0002] White ash, also known as light-burned clay or barite, is a mixture mainly composed of calcium carbonate and magnesium carbonate. In the steelmaking process, adding a certain amount of white ash can play the following roles:

[0003] 1. Lower the furnace temperature. Adding lime can absorb some heat, thereby lowering the furnace temperature, protecting the furnace lining, and extending the service life of the furnace;

[0004] 2. Improve the refining effect. During the steelmaking process, lime reacts with lime to generate calcium oxide and magnesium oxide, releasing carbon dioxide. The gases produced by these reactions can take away some impurities and debris, improving the quality of molten steel. At the same time, calcium oxide and magnesium oxide can also combine with sulfur, phosphorus and other elements to form corresponding oxides, which are removed through the slag, thereby improving the purity and composition stability of the molten steel.

[0005] After the production of lime is completed, it is generally in a block structure. In order to meet the production needs of steelmaking, lime kilns generally produce and store lime in large quantities. However, due to the characteristics of lime absorbing water and moisture, its chemical properties are very easy to change. In order to ensure the stability of the performance of lime, at this stage, some lime is stored in storage tanks, and the storage tanks are generally equipped with heating devices on their outer walls. These heating devices are generally heating rods or heating fans, which increase the temperature in the storage tanks through heat conduction to prevent the lime from getting damp and deteriorating. However, some existing storage tanks are usually heated only on the surface of the tank body, and the lime inside the tank is not evenly heated. In this way, some lime will inevitably have storage problems, which seriously affects the stability of the lime and also affects the subsequent steelmaking operations. Utility Model Content

[0018] Figure 2 is Figure 1 the enlarged view at A in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to more clearly understand the above objects, features, and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0021] Such as Figure 1-2As shown in the figure, a lime block storage device in this embodiment includes a storage tank 1. Feed inlets 2 and discharge outlets 3 are respectively arranged at the upper and lower ends of the storage tank 1. A heating pipe 4 is arranged in the middle of the storage tank 1. A plurality of partition plates 5 are evenly distributed along the circumferential direction on the inner wall of the storage tank 1. The partition plates 5 cooperate with the inner wall of the storage tank 1 to form a heating cavity. Heating rods 6 are arranged in the heating cavity. Inlet pipes 7 and exhaust pipes 8 are arranged at the upper and lower ends of the heating pipe 4. Both the inlet pipes 7 and the exhaust pipes 8 extend outward from the storage tank 1. The inlet pipes 7 are connected to heating equipment.

[0022] Both the inlet pipes 7 and the exhaust pipes 8 penetrate through the heating cavity, and a heat storage body 9 is also arranged in the heating cavity.

[0023] The heating pipe 4 is provided with a conical pipe cap 10 at its top. The tip of the pipe cap 10 faces the feed inlet 2. The pointed pipe cap 10 can guide the lime material entering along the feed inlet 2, so that it slides downward in the storage tank 1, thereby preventing lime from accumulating on the heating pipe 4.

[0024] The side wall of the heating pipe 4 is provided with first heat exchange fins 11.

[0025] The partition plates 5 are provided with second heat exchange fins 12 on the side away from the heating cavity.

[0026] The first heat exchange fins 11 and the second heat exchange fins 12 can greatly improve the heat exchange effect, thereby ensuring the dryness of the lime.

[0027] A fixed connecting rod 13 is arranged outside the heating pipe 4. The fixed connecting rod 13 is fixedly connected to the partition plates 5 or the inner wall of the storage tank 1.

[0028] A discharge valve 14 is arranged at the discharge outlet 3. By controlling the opening and closing of the discharge valve 14, the lime discharge in the storage tank 1 can be controlled.

[0029] Preferably, the heating equipment is a hot air blower, and the hot air blower sends hot air into the heating pipe 4.

[0030] Preferably, the heat storage body 9 is a ceramic heat storage block.

[0031] The working principle of the present utility model is as follows: The produced quicklime blocks are conveyed through the feed inlet 2 to the inside of the storage tank 1. The quicklime blocks are stored in the storage tank 1. Subsequently, the heating rod 6 and the heating device are controlled to start. As the heating rod 6 heats up, the inside of the storage tank 1 can be heated. During the heating process, the heat storage body 9 will store a part of the heat. At the same time, the heating device sends hot air into the heat supply pipe 4 through the air inlet pipe 7. After the hot air enters the heat supply pipe 4, it exchanges heat with the inside of the storage tank 1, thereby increasing the temperature inside the storage tank 1. Then the hot air will be discharged at the exhaust pipe 8. When the hot air flows through the air inlet pipe 7 and the exhaust pipe 8, the heat in the pipeline is also absorbed by the heat storage body 9 at the same time. The heat stored in the heat storage body 9 can maintain the temperature inside the storage tank 1, thus saving energy consumption. In this way, by heating the inside of the storage tank 1 both inside and outside, the drying of the quicklime inside the storage tank 1 can be ensured. When the quicklime needs to be used, the discharge valve 14 on the discharge port 3 is opened, and the quicklime can be discharged and used through the discharge port 3.

[0032] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
