Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, in particular to a calcining device for magnesium-calcium refractory materials. Background Art

[0002] Magnesia-calcium refractory materials not only do not pollute molten steel but also purify it. They also possess excellent high-temperature resistance, slag resistance, thermal shock resistance, and stability under high-temperature vacuum conditions. They are high-quality alkaline refractory materials and the most suitable refractory materials for smelting clean steel, earning widespread attention from steel companies. The preparation of magnesium-calcium refractory materials requires calcination equipment, commonly used in high-temperature converters or hot furnaces. This is done to filter impurities from the material before it enters the furnace, improving calcination quality.

[0003] For example, a calcining device for magnesium-calcium refractory materials with the authorization announcement number CN117404912B includes a hot furnace, a charging port is opened on the front side of the hot furnace, and calcining rollers are connected in the left and right directions in the calcining chamber. There are several calcining rollers, which are distributed in sequence along the front and back directions of the calcining chamber. The left and right ends of the calcining rollers pass through the left and right sides of the calcining chamber and are connected through bearings. The calcining rollers are provided with calcining rails. The ends of the adjacent calcining rollers are connected by a small gear transmission. One end of the calcining roller on the rear side is fixed with a large gear located on the outside of the calcining chamber. The heat is fed back to the upper chamber through the gap, and the rod-shaped material placed in the upper chamber is calcined. The air supply nozzles can also continue to supply air at this time. When the air supply nozzles at the bottom are supplied with air, the airflow acts on the lower cavity, helping the heat in the lower cavity to pass through the gap and fully act on the rod-shaped material above the gap, thereby increasing the effective area and increasing the temperature at the same time, thereby improving the calcination efficiency. However, the impurities generated in the calcination process of the magnesium-calcium refractory material calcining device in the above-mentioned document directly fall into the bottom of the calcining furnace, making it difficult for personnel to clean the impurities due to the high temperature of the calcining furnace space and the small space of the calcining furnace, which is inconvenient for personnel to clean.

DETAILED DESCRIPTION

[0042] The present invention will be further described below with reference to the accompanying drawings:

[0043] The utility model proposes a calcining device for magnesium-calcium refractory materials, such as Figure 1 As shown, it includes a calcining furnace 1, a base 2 and an auxiliary structure 3. The bottom end of the calcining furnace 1 is fixedly connected to the base 2, and the inner cavity of the calcining furnace 1 is connected to the collecting cavity 203 of the base 2. Connecting holes 201 are respectively provided on both sides of the calcining furnace 1. The connecting holes 201 on both sides are mirror-imaged on both sides of the base 2. Guide grooves 202 are provided on both sides of the collecting cavity 203, and an auxiliary structure 3 is provided inside the collecting cavity 203.

[0044] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the auxiliary structure 3 includes a collecting seat 301, a connecting frame 302, a positioning assembly 303, a baffle 304 and a limiting assembly 305;

[0045] The collecting seat 301 is arranged inside the collecting chamber 203, and the collecting seat 301 is in contact with the collecting chamber 203. Impurities generated when the calcining furnace 1 calcines the magnesium-calcium refractory material fall into the collecting seat 301. Guide rails 3011 are provided on both sides of the collecting seat 301. The guide rails 3011 match the guide grooves 202. The collecting seat 301 can drive the guide rails 3011 to move along the guide grooves 202, ensuring that the collecting seat 301 can slide stably and avoid the collecting seat 301 from tilting during the sliding process. Sockets 3012 are respectively provided on the inner side of the collecting seat 301. The sockets 3012 on both sides are mirror-imaged and are used to connect to the limit assembly 305.

[0046] The inner end of the connecting frame 302 is fixedly connected to the collecting seat 301, and the inner ends of both sides of the connecting frame 302 are in contact with the base 2. The end of the connecting frame 302 is fixedly connected to the handle 3021, and the handle 3021 drives the collecting seat 301 to move through the connecting frame 302. Guide holes 3022 are respectively provided on both sides of the connecting frame 302. A positioning assembly 303 is provided on the outer side of the connecting frame 302 for fixing the connecting frame 302 so that the collecting seat 301 can better fit with the base 2, ensuring that a gap between the collecting seat 301 and the base 2 causes impurities to fall into the interior of the collecting chamber 203;

[0047] The positioning assembly 303 includes a U-shaped seat 3031, a first spring 3032, a slider 3033, a rotating rod 3034 and a block 3035. The outer wall of the block 3035 matches the connecting hole 201 and the guide hole 3022. The block 3035 can slide in the guide hole 3022 and the connecting hole 201. The two sides of the rotating rod 3034 of the block 3035 are rotatably connected to the slider 3033 and the block 3035 respectively. The two sides of the slider 3033 and the two sides of the block 3035 are both in contact with the U-shaped seat 3031. When the rotating rod 3034 is rotated, the rotating rod 3034 is rotated. The slider 3033 and the block 3035 are restricted by the U-shaped seat 3031, so that the rotating rod 3034 rotates along the slider 3033 and the block 3035, while the slider 3033 and the block 3035 do not rotate with the rotating rod 3034. The two ends of the first spring 3032 are fixedly connected to the U-shaped seat 3031 and the slider 3033 respectively, and the elastic force of the first spring 3032 is used to restrict the block 3035. A connecting groove 3036 is provided on one side of the U-shaped seat 3031, and the middle section of the rotating rod 3034 matches the connecting groove 3036.

[0048] Specifically, when the operator pulls the rotating rod 3034, the rotating rod 3034 drives the block 3035 and the slider 3033 to move, and the slider 3033 drives the first spring 3032 to compress. When the block 3035 is separated from the connecting hole 201, the rotating rod 3034 is rotated, and the middle section of the rotating rod 3034 matches the connecting groove 3036, so that the middle section of the rotating rod 3034 and the connecting groove 3036 restrict the block 3035 from moving due to the elastic force of the first spring 3032. Similarly, the rotating rod 3034 on the other side is rotated. The movable rod 3034 is connected to the corresponding connecting groove 3036. Then, the handle 3021 is pulled, so that the handle 3021 can drive the collection seat 301 to move and separate from the collection chamber 203 through the connecting frame 302. After the collection seat 301 is connected to the collection chamber 203, the rotating rod 3034 is pulled to separate the rotating rod 3034 from the connecting groove 3036. The elastic force of the first spring 3032 drives the clamping block 3035 along the guide hole 3022 to engage with the connecting hole 201, thereby fixing the collection seat 301.

[0049] The side of the collecting seat 301 away from the connecting frame 302 is hinged to the baffle 304. The baffle 304 is provided with a slide groove 3041 on both sides. The side end of the slide groove 3041 is provided with a rectangular groove 3042 for connecting the limit assembly 305.

[0050] The limiting assembly 305 includes an insert block 3051, a second spring 3052 and a rectangular block 3053. The two ends of the second spring 3052 are fixedly connected to the insert block 3051 respectively. The elastic force of the second spring 3052 can limit the movement of the insert block 3051. The insert block 3051 matches the slide groove 3041. The insert block 3051 can slide along the slide groove 3041. A rectangular block 3053 is provided at the end of the insert block 3051. The rectangular block 3053 can slide along the rectangular groove 3042. The rectangular block 3053 drives the insert block 3051 to move. One side of the insert block 3051 matches the socket 3012 to limit the flipping of the baffle 304.

[0051] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, impurities generated when the calcining furnace 1 calcines the magnesium-calcium refractory material fall into the interior of the collecting seat 301. When cleaning the impurities in the collecting seat 301, when the personnel pulls the rotating rod 3034, the rotating rod 3034 simultaneously drives the block 3035 and the slider 3033 to move, and the slider 3033 drives the first spring 3032 to compress. When the block 3035 is separated from the connecting hole 201, the rotating rod 3034 is rotated, and the middle section of the rotating rod 3034 matches the connecting groove 3036, so that the middle section of the rotating rod 3034 is matched with the connecting groove 3036. 6. The clamping block 3035 is restricted so that it will not move due to the elastic force of the first spring 3032. Similarly, the rotating rod 3034 on the other side is connected to the corresponding connecting groove 3036. Then, the handle 3021 is pulled so that the handle 3021 can drive the collection seat 301 to move and separate from the collection chamber 203 through the connecting frame 302. Then, the rectangular blocks 3053 on both sides are moved inward at the same time. The rectangular blocks 3053 drive the insertion block 3051 to separate from the insertion hole 3012. Then, the baffle 304 is flipped over, and the impurities inside the collection seat 301 are cleaned.

[0052] After the cleaning is complete, the baffle 304 is reset, and then the collection seat 301 is connected to the collection chamber 203 and the rotating rod 3034 is pulled to separate the rotating rod 3034 from the connecting groove 3036. The elastic force of the first spring 3032 drives the clamping block 3035 to be clamped with the connecting hole 201 along the guide hole 3022, thereby fixing the collection seat 301.
