Description

Technical Field

[0001] This utility model relates to the field of iron and steel smelting technology, specifically a distributed energy waste heat utilization device. Background Technology

[0002] In the steel smelting process, the steel ingots or billets produced in a red-hot state are transferred on the guide roller conveyor, during which a large amount of heat is released, resulting in a waste of thermal energy. At the same time, this heat will also cause the temperature in the production workshop to rise, and the working environment for workers to deteriorate.

[0003] The patent document with announcement number CN217058404U describes a waste heat recovery and circulation device for smelting steel, which effectively recovers the heat emitted by steel ingots or billets during transportation. However, the device completely encloses the guide roller conveyor frame, which is not conducive to the subsequent maintenance of the guide roller conveyor frame.

[0004] Based on this, a distributed energy waste heat utilization device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-3 As shown, a distributed energy waste heat utilization device includes a fixed frame 101 fixed on the ground. Multiple guide rollers 102 are rotatably and equidistantly arranged on the fixed frame 101. Multiple lower heat collection covers 103 are connected to the fixed frame 101 through a load-bearing structure. Multiple upper heat collection covers 104 are connected to the fixed frame 101 through a limiting structure. An insertion structure is provided between the lower heat collection covers 103 and the upper heat collection covers 104. A support frame 106 is provided on the fixed frame 101. A heat-conducting square tube 105 is provided on the support frame 106. The heat-conducting square tube 105 is in sliding contact with the support frame 106. A pressing structure is provided on the upper heat collection covers 104.

[0025] In this embodiment, the lower heat collector 103 is connected to the fixing frame 101 via a load-bearing structure. The upper heat collector 104 is inserted into the lower heat collector 103, and heat is transferred between the lower heat collector 103 and the upper heat collector 104 through contact. The limiting structure simultaneously restricts the lower heat collector 103 and the upper heat collector 104 through the insertion structure, thereby fixing the lower heat collector 103 and the upper heat collector 104 to the fixing frame 101. The heat-conducting square tube 105 is pressed tightly onto the upper heat collector 104 by the pressing structure. The upper heat-conducting square tube 105 and the upper heat-collecting cover 104 are used to achieve heat conduction. The lower heat-collecting cover 103 and the upper heat-collecting cover 104 are both distributed on the fixed frame 101. When maintaining some of the guide rollers 102, it is only necessary to remove the lower heat-collecting cover 103 and the upper heat-collecting cover 104 at the guide roller 102 to be maintained. The disassembly process is simple. A heat-conducting medium is introduced into the heat-conducting square tube 105 to realize the recovery and utilization of a large amount of heat emitted during the transfer of steel ingots or billets in a red-hot state.

[0026] In one embodiment, such as Figure 3 As shown, the load-bearing structure includes load-bearing grooves 201 symmetrically arranged on the fixed frame 101. The load-bearing grooves 201 are L-shaped. A load-bearing column 202 is provided on the outer side of the lower heat collector 103 corresponding to the position of the load-bearing groove 201. The outer diameter of the load-bearing column 202 matches the width of the load-bearing groove 201. During installation, the load-bearing column 202 is first slid into the vertical section of the load-bearing groove 201 from bottom to top. Then, the lower heat collector 103 is moved horizontally so that the load-bearing column 202 slides into the horizontal section of the load-bearing groove 201, thereby realizing the support of the fixed frame 101 for the lower heat collector 103.

[0027] In one embodiment, such as Figure 3As shown, the limiting structure includes limiting grooves 203 symmetrically arranged on the fixed frame 101. The limiting grooves 203 are vertical grooves. A limiting post 204 is provided on the outer side of the upper heat collector cover 104 corresponding to the limiting groove 203. The outer diameter of the limiting groove 203 matches the width of the limiting groove 203. When the upper heat collector cover 104 is lowered from above the fixed frame 101, the limiting post 204 slides into the limiting groove 203. The limiting groove 203 limits the upper heat collector cover 104 through the limiting post 204.

[0028] In one embodiment, such as Figure 3 As shown, the insertion structure includes an upward-facing insertion groove 205 on the lower heat collector cover 103, the position of which corresponds to the position of the guide roller 102. The upper heat collector cover 104 is provided with an insertion block 206 that matches the insertion groove 205. The insertion block 206 is provided with a guide slope. When the upper heat collector cover 104 is lowered, the guide slope on the insertion block 206 contacts the edge of the insertion groove 205. Under the action of the limiting structure, the lower heat collector cover 103 moves horizontally, so that the insertion groove 205 is directly opposite the insertion block 206. When the upper heat collector cover 104 is lowered into place, the insertion between the lower heat collector cover 103 and the upper heat collector cover 104 is completed. The contact surface between the lower heat collector cover 103 and the upper heat collector cover 104 is flat and smooth, which is conducive to heat conduction.

[0029] In one embodiment, such as Figure 1 and Figure 2 As shown, the clamping structure includes a T-shaped fixing block 301 disposed on the outside of the upper heat collection cover 104. An L-shaped plug plate 302 is inserted into the T-shaped fixing block 301. A clamping arm 303 is connected to the L-shaped plug plate 302. A clamping screw 304 is threaded through the clamping arm 303. A clamping block 305 is rotatably connected to one end of the clamping screw 304 near the heat-conducting square tube 105. A force-applying rod 306 is inserted through the other end of the clamping screw 304 away from the heat-conducting square tube 105. By rotating the clamping screw 304 through the force-applying rod 306, the clamping block 305 is pressed against the heat-conducting square tube 105, so that the heat-conducting square tube 105 is tightly attached to the upper heat collection cover 104, thereby realizing the heat transfer between the upper heat collection cover 104 and the heat-conducting square tube 105.

[0030] The above embodiment discloses a distributed energy waste heat utilization device, wherein the upper heat collector 104 and the heat-conducting square tube 105 collect a large amount of heat emitted during the transfer of steel ingots or castings in a red-hot state. During installation, the supporting column 202 is first slid into the vertical section of the supporting groove 201 from bottom to top, and then the lower heat collector 103 is moved horizontally so that the supporting column 202 slides into the horizontal section of the supporting groove 201. Then the upper heat collector 104 is lowered from above the fixing frame 101, and the limiting column 204 slides into the limiting groove 203. When the upper heat collector 104 is lowered, the guide slope on the insertion block 206 contacts the edge of the insertion groove 205. Under the action of the limiting structure, the lower heat collector 103 moves horizontally. At this time, the supporting column 202 is still located in the supporting groove 201. In the horizontal section 1, the insertion slot 205 is aligned with the insertion block 206. When the upper heat collector cover 104 is lowered into place, the insertion between the lower heat collector cover 103 and the upper heat collector cover 104 is completed. Finally, by rotating the clamping screw 304 through the force bar 306, the clamping block 305 is pressed against the heat-conducting square tube 105, so that the heat-conducting square tube 105 is tightly attached to the upper heat collector cover 104, realizing the heat transfer between the upper heat collector cover 104 and the heat-conducting square tube 105. The heat-conducting medium is introduced into the heat-conducting square tube 105 to realize the recovery of waste heat. The lower heat collector cover 103 and the upper heat collector cover 104 of this device are distributed on the fixed frame 101. When maintaining some of the guide rollers 102, it is only necessary to remove the lower heat collector cover 103 and the upper heat collector cover 104 at the guide roller 102 to be maintained. The disassembly process is simple.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
