[0002] A furnace is a device that melts metal ingots and some scrap metals and adds necessary alloy components, and then melts them into the required alloys through operations such as slagging and refining. It is widely used in the modern scrap metal recycling process. Waste heat is energy that is not utilized in energy utilization equipment under certain economic and technical conditions, that is, it is not directly used in any link of the production process. Waste heat recovery is an important way to improve economy and save fuel.

[0003] A large amount of heat is released during the metal smelting process in a dumping furnace, and a heat-absorbing device is required to recover and reuse the waste heat of the high-temperature flue gas above the furnace. The temperature of the waste heat will gradually decrease over time, so the heat-absorbing device is required to adjust the distance between the main body and the furnace body according to the temperature change. Under initial conditions, when the distance between the heat-absorbing device and the furnace body is too short, it will affect the placement of the metal inside the furnace body; when the waste heat temperature is high, it will cause damage to the heat-absorbing device; when the waste heat temperature is lowered, the distance between the heat-absorbing device and the furnace body is long, which will affect the waste heat recovery effect.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The device adjusts the distance between the heat absorbing component and the furnace body by cooperating with a telescopic rod and a temperature sensor, so that the heat absorbing component can automatically adjust its height according to the temperature change of the furnace body, thereby avoiding the problem that the height of the heat absorbing component is fixed, resulting in the heat absorbing component being unable to effectively recover the low-temperature waste heat inside the furnace body when the temperature of the furnace body gradually decreases.

[0016] (2) When the heat absorbing component gradually lowers its height, it will contact the upper surface of the surrounding mechanism, squeeze the gas inside the lower pressure box through the lower pressure plate, and push the sealing plates on both sides of the furnace body to contact each other. That is, the sealing plates on both sides of the furnace body can be separated and merged as the height of the heat absorbing component changes. When separated, it will not hinder the placement of metal into the interior of the furnace body. When merged, it can cooperate with the surrounding box to roughly seal the four sides of the furnace body, so that the smoke can only flow upward along the inner wall of the surrounding box, thereby preventing the smoke and heat from the furnace from escaping to the surroundings, resulting in the problem of the heat absorbing equipment absorbing less smoke and waste heat.

[0017] (3) After the smelting of metal is completed, the furnace body will tilt at a certain angle, and the position of the emitted smoke will change during the tilting rotation of the furnace body, that is, the smoke flow position moves forward a certain distance. The push plate can rotate synchronously with the furnace body as the motor output shaft rotates, and the push plate can drive the lifting mechanism and the heat absorbing component to move forward an appropriate distance during the rotation, that is, the heat absorbing component can adjust its own moving distance as the furnace body rotates, so that the heat absorbing component can be located above the smoke flow path to a large extent, increasing the contact area between the smoke pipe and the smoke, and avoiding the problem of the smoke emission path changing due to the rotation of the furnace body, resulting in a reduction in the contact area between the heat absorbing device and the smoke, and causing difficulty in absorbing heat.

[0018] (4) The equipment absorbs the heat in the flue gas through the heat-absorbing component, so as to realize the recovery and utilization of the waste heat in the metal smelting process. The cleaning plate slides along the lower surface and the inner wall of the smoking pipe, and can scrape the attached black stains and impurity particles into the inside of the collection box. On the one hand, it can clean the smoking pipe and avoid the narrowing of the channel and the blockage of the wire groove due to the long-term accumulation of impurities on the surface and inside of the smoking pipe, which will cause the smoking pipe to absorb the flue gas and waste heat more slowly; on the other hand, it can avoid the excessive accumulation of black oil stains, which will eventually gather together and drip onto the inner wall of the furnace body, thereby affecting the subsequent metal smelting work of the furnace body.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0031] For the first embodiment, please refer to Figure 1-Figure 7 The present invention is a dumping furnace waste heat recovery device, comprising a tripod 1, a motor 2 is fixedly connected to the upper surface of the tripod 1, a furnace box 3 is fixedly connected to the output shaft of the motor 2, a furnace body 4 is fixedly connected to the inner wall of the furnace box 3, a chute 5 is provided on the inner wall of the furnace box 3, a surrounding mechanism 6 is slidably connected to the inner wall of the chute 5, and a lifting mechanism 7 is fixedly connected to the upper surface of the tripod 1; after the furnace body 4 completes the melting of the metal, the output shaft and the furnace box 3 and the furnace body 4 are driven by the motor 2 to rotate, so as to complete the dumping of the molten metal by the furnace. The chute 5 facilitates the sliding of the surrounding mechanism 6 on its inner wall.

[0032] The lifting mechanism 7 includes a heat absorbing component 71, a sliding box 72 is fixedly connected to the front side of the heat absorbing component 71, a plug rod 73 is fixedly connected to the bottom of the heat absorbing component 71, a telescopic rod 74 is fixedly connected to the bottom of the heat absorbing component 71, a limit box 75 is fixedly connected to the bottom of the outside of the telescopic rod 74, a push plate 76 is slidably connected to the outer surface of the limit box 75, rollers 77 are rotatably connected to both sides of the limit box 75, a support frame 78 is rotatably connected to the outer surface of the roller 77, and a transverse groove 79 is provided on the inner wall of the support frame 78. The side of the sliding box 72 close to the heat absorbing component 71 is inserted into the interior of the heat absorbing component 71, and the sliding box 72 can be pulled out when necessary. The extension and contraction of the telescopic rod 74 can drive the entire heat absorbing component 71 to move up and down, and the bottom of the support frame 78 is fixed to the upper surface of the tripod 1.

[0033] The telescopic rods 74 are symmetrically arranged on both sides of the fixed frame 711, the side of the roller 77 away from the limit box 75 is slidably connected to the inner wall of the support frame 78, the inner wall of the push plate 76 is fixedly connected to the outer surface of the output shaft of the motor 2, and the outer surface of the push plate 76 is slidably connected to the inner wall of the transverse groove 79. The output shaft of the motor 2 can drive the push plate 76 to rotate when it rotates, and the push plate 76 can push the limit box 75 and the roller 77 to move along the inner wall of the support frame 78 during the rotation process.

[0034] The present invention drives the furnace to tilt through the motor 2 and the output shaft of the motor 2. During the process of melting metal in the furnace, the lifting mechanism 7 can absorb the residual heat above the furnace body 4 through the heat absorbing component 71. The lifting mechanism 7 can adjust the height of the heat absorbing component 71 according to the change of the temperature of the furnace body 4. During the descent of the lifting mechanism 7, it will touch the surrounding mechanism 6, and complete the basic sealing treatment of the space above the furnace body 4 and the surrounding space together with the surrounding mechanism 6 to prevent smoke from escaping to the surroundings of the furnace body 4.

[0035] When in use, in the initial state, the lifting mechanism 7 drives the heat absorbing component 71 to move upward a certain distance to ensure that the furnace body 4 and the upper part of the surrounding mechanism 6 leak out without hindering the staff from placing the metal into the furnace body 4.

[0036] When the furnace body 4 is in the process of melting the molten metal, a lot of high temperature and smoke will appear. When the temperature is high, the heat absorbing component 71 is located above the furnace body 4 to absorb the rising smoke. After the furnace body 4 completes the melting of the metal, or the pouring of the molten metal is completed, and the furnace body 4 is reset, the temperature inside the furnace body 4 will gradually decrease with the change of time. At this time, it is necessary to lower the height of the heat absorbing component 71 so that the heat absorbing component 71 can adjust the distance between the component and the furnace body 4 according to the change of the temperature of the furnace body 4. Before the furnace body 4 melts the metal, there is a certain height distance between the heat absorbing component 71 and the furnace body 4, which is convenient for the staff to put the metal into the furnace body 4 without affecting the staff. Therefore, the heat absorbing component 71 can adjust the height of the heat absorbing component 71 by extending and contracting the telescopic rod 74.

[0037] After the furnace body 4 completes melting of the metal, it is necessary for the furnace body 4 to rotate forward to facilitate pouring out the internal solution. During the pouring process of the furnace body 4, the position of the smoke from the furnace body 4 will change with the rotation of the furnace body 4. When the furnace body 4 rotates to a certain extent, the position of the smoke from the furnace body 4 outlet will move forward a certain distance.

[0038] When the motor 2 is started, the output shaft can drive the furnace box 3 and the furnace body 4 to rotate slowly, and the output shaft can also drive the rotation of the push plate 76. When the push plate 76 rotates forward by a certain angle, it can push the limit box 75 and the rollers 77 on both sides to move forward along the inner wall of the support frame 78. The setting of the transverse groove 79 facilitates the rotation of the push plate 76. When the limit box 75, the rollers 77 and the telescopic rod 74 move along the inner wall of the support frame 78, they can also drive the heat absorbing component 71 at the top of the telescopic rod 74 to move. When the heat absorbing component 71 moves forward by a certain distance with the rotation of the push plate 76, it can move forward by an appropriate distance along the top of the smoke of the furnace body 4, thereby increasing the contact area between the heat absorbing component 71 and the smoke, and avoiding the change of the smoke position during the tilting of the furnace, resulting in the problem that the heat absorbing component 71 has a reduced absorption of smoke and internal waste heat, and the smoke and waste heat above the furnace body 4 are absorbed again by the heat absorbing component 71.

[0039] The heat absorbing component 71 includes a fixed frame 711, a heat exchanger 712 is fixedly connected to the upper surface of the fixed frame 711, a smoking pipe 713 is fixedly connected to the input end of the heat exchanger 712, an air intake pipe of a smoking device 714 is fixedly connected to the inner wall of the smoking pipe 713, a wire groove 715 is provided at the bottom of the inner wall of the smoking pipe 713, a cleaning component 716 is slidably connected to the lower surface of the smoking pipe 713, an electric rod 717 is fixedly connected to the side of the cleaning component 716 close to the sliding box 72, and a limiting plate 718 is rollingly connected to the outer surface of the cleaning component 716. The fixed frame 711 is arranged above the surrounding mechanism 6, the smoking device 714 and the smoking pipe 713 absorb the flue gas in the process of melting metal in the furnace, and the heat exchanger 712 is used to absorb the residual heat and high temperature in the flue gas absorbed by the smoking pipe 713. The smoking device 714 is equipped with an air intake pipe.

[0040] The sliding box 72 is fixedly connected to the inner wall of the fixed frame 711, the bottom of the fixed frame 711 is fixedly connected to the upper surface of the plug 73, both sides of the fixed frame 711 are fixedly connected to the outer surface of the smoking device 714, the end of the electric rod 717 away from the cleaning component 716 is fixedly connected to the inner wall of the sliding box 72, and the limiting plate 718 is fixedly connected to the inner wall of the fixed frame 711.

[0041] When in use, the smoking pipe 713 is located above the furnace body 4, and a large amount of smoke generated during the operation of the furnace body 4 is absorbed by the smoking pipe 713 and the smoking device 714. The heat exchanger 712 absorbs the heat of the smoke in the smoking pipe 713, and a wire groove 715 is provided at the bottom of the smoking pipe 713 to facilitate the absorption of smoke and the subsequent cleaning of the inner wall of the smoking pipe 713. After the smoking pipe 713 has been working for a long time, a large amount of smoke and particulate impurities appear inside, and the cleaning component 716 is used to clean the inner wall of the smoking pipe 713. The smoking pipes 713 are interconnected, so that the smoking device 714 can facilitate the smoking work inside multiple smoking pipes 713.

[0042] The cleaning component 716 includes a cleaning plate 7161, a rotating shaft 7162 is fixedly connected to one side of the cleaning plate 7161 close to the limiting plate 718, a supporting wheel 7163 is fixedly connected to one end of the rotating shaft 7162 away from the cleaning plate 7161, a circular ring 7164 is fixedly connected to the upper surface of the cleaning plate 7161, a collecting box 7165 is fixedly connected to the bottom of the cleaning plate 7161, the upper surface of the cleaning plate 7161 is slidably connected to the lower surface of the smoking pipe 713, and the outer surface of the supporting wheel 7163 is rollingly connected to the outer surface of the limiting plate 718. The electric rod 717 can drive the movement of the cleaning plate 7161, the rotating shaft 7162 and the supporting wheel 7163 during the extension and contraction process, and the supporting wheel 7163 rolls on the surface of the limiting plate 718, and the limiting plate 718 provides support and limiting for the rolling of the supporting wheel 7163. The cleaning plate 7161 can scrape off the dust and granular impurities on the lower surface of the smoking pipe 713 when it moves toward the side of the sliding box 72, and the ring 7164 can scrape off the impurities attached to the inner wall of the smoking pipe 713.

[0043] When in use, the electric rod 717 can drive the cleaning plate 7161, the rotating shaft 7162 and the supporting wheel 7163 located on one side of the heat exchanger 712 to move toward the side away from the heat exchanger 712 during the contraction process. The cleaning plate 7161 will move along the lower surface of the smoking pipe 713 during the movement to scrape off the black stains on the lower surface of the smoking pipe 713. The stains and granular impurities during the scraping process will fall onto the upper surface of the cleaning plate 7161 and slide along the surface of the cleaning plate 7161 to the inside of the collection box 7165 at the bottom. The cleaning plate 7161 will also drive the movement of the ring 7164 during the movement. The ring 7164 can slide along the inner wall of the smoking pipe 713 during the movement to scrape off the stains and granular impurities on the inner wall of the smoking pipe 713.

[0044] The cleaning effect of the surface and inner wall of the smoking pipe 713 can scrape off the oil stains and impurities attached to the surface, which can clean the smoking pipe 713 on the one hand, and avoid the narrowing of the passage of the smoking pipe 713 and the reduction of the absorption degree of smoke due to excessive accumulation of impurities on the surface and the inner wall for a long time. On the other hand, it can also avoid excessive accumulation of black oil stains attached to the surface of the smoking pipe 713, which eventually drips onto the inner wall of the furnace body 4, further affecting the melting work of the furnace body 4 on the metal.

[0045] The rear end of the electric rod 717 is fixed to the inner wall of the sliding box 72, and the sliding box 72 can slide and separate from the inner wall of the fixed frame 711. At the beginning, the sliding box 72 can be inserted into the inner wall of the fixed frame 711, and when separated, the sliding box 72 can slide and separate from the fixed frame 711. When the impurities inside the multiple collection boxes 7165 are full, the electric rod 717 can be retracted to move the cleaning component 716 to the side close to the sliding box 72. When the sliding box 72 is separated from the fixed frame 711, the collection box 7165 inside the fixed frame 711 is exposed to the field of vision, and the collection box 7165 can be disassembled and replaced with a new collection box 7165, which is convenient for the subsequent cleaning and collection work of the cleaning component 716.

[0046] For the second embodiment, please refer to Figure 1-Figure 10 The present invention is a dumping furnace waste heat recovery device, the surrounding mechanism 6 includes a surrounding box 61, the bottom of the surrounding box 61 is fixedly connected with a compression spring 62, the inner wall of the bottom of the surrounding box 61 is fixedly connected with a temperature sensor 63, the inner wall of the surrounding box 61 is slidably connected with a pressing component 64, and the upper surface of the pressing component 64 is provided with a circular groove 65. The temperature sensor 63 is used to detect the temperature inside the furnace box 3 and the surface of the furnace body 4, and the plug 73 is used in conjunction with the circular groove 65.

[0047] The pressing component 64 includes a pressing plate 641, a compression spring 642 is fixedly connected to the bottom of the pressing plate 641, a pressing box 643 is slidably connected to the outer surface of the pressing plate 641, a through hole 644 is provided on the inner wall of the pressing box 643, a push spring 645 is fixedly connected to the side of the pressing box 643 close to the through hole 644, and a sealing component 646 is fixedly connected to the end of the push spring 645 away from the pressing box 643. The pressing plate 641 can squeeze the gas inside the pressing box 643 when sliding downward along the inner wall of the surrounding box 61.

[0048] The sealing component 646 includes a sealing plate 6461, the inner wall of which is rotatably connected to a moving wheel 6462, the inner wall of which is fixedly connected to a rubber rod 6463, and the end of the rubber rod 6463 away from the sealing plate 6461 is fixedly connected to a telescopic plate 6464. When the gas inside the pressing box 643 is squeezed, the gas will push the sealing component 646 to move to the side away from the pushing spring 645 through the through hole 644, and the surrounding mechanism 6 is symmetrically arranged on both sides of the furnace body 4.

[0049] The outer surface of the enclosing box 61 is slidingly connected to the inner wall of the slide groove 5, the bottom of the compression spring 62 is fixedly connected to the bottom of the inner wall of the slide groove 5, the outer surface of the lower pressure plate 641 is slidingly connected to the inner wall of the enclosing box 61, the outer surface of the sealing plate 6461 is slidingly connected to the inner wall of the enclosing box 61, the outer surface of the moving wheel 6462 is rollingly connected to the inner wall of the enclosing box 61, and the outer surface of the telescopic rod 74 is slidingly connected to the inner wall of the sealing plate 6461.

[0050] When in use, under the initial condition, the sealing plates 6461 located inside the surrounding boxes 61 on both sides of the furnace body 4 have not yet been attached together, and will not hinder the staff from putting the metal into the furnace body 4. Later, during the process of melting the metal in the furnace, or after the furnace body 4 completes the pouring of the molten metal and resets, as the lifting mechanism 7 drives the heat absorbing device to move downward continuously, the fixed frame 711 can also drive the plunger 73 to move downward. After moving downward for a certain distance, the plunger 73 will contact the circular groove 65 and push the circular groove 65 and the pressing part 64 to move downward. The circular groove 65 is not completely penetrated. As the plunger 73 squeezes the circular groove 65, that is, squeezes the pressing part 64, the lower pressing plate 641 can be pushed to slide downward along the inner wall of the surrounding box 61. During the downward movement, the lower pressing plate 641 can slide along the inner wall of the lower pressing box 643, which can squeeze the gas inside the lower pressing box 643 and the squeezing spring 642 at the bottom of the lower pressing plate 641. The squeezed gas can flow out through the through hole 644 and squeeze the sealing component 646, pushing the sealing component 646 to slide outward along the inner wall of the surrounding box 61. When the sealing components 646 on both sides of the furnace box 3 slide toward the side away from the surrounding box 61, they can eventually fit together to achieve the enclosure of the front and rear sides of the furnace box 3.

[0051] When the sealing plates 6461 at the front and rear of the surrounding box 61 are merged, the surrounding box 61 and the sealing plates 6461 can wrap the four sides of the furnace body 4, and cooperate with the contact of the upper heat absorption device to prevent the smoke from escaping to the four sides of the furnace body 4, so that the heat absorption device can better absorb the smoke.

[0052] When the bottom of the lower pressure plate 641 contacts the upper surface of the lower pressure box 643, the lower pressure plate 641 can no longer slide downward along the inner wall of the lower pressure box 643. Therefore, the lower pressure plate 641 will only push the lower pressure box 643 and the entire surrounding box 61 to slide downward along the inner surface of the slide groove 5, and at the same time squeeze the compression spring 62 at the bottom of the surrounding box 61. When the surrounding box 61 slides downward, the telescopic plate 6464 located inside the sealing plate 6461 slides upward along the inner wall of the sealing plate 6461 and squeezes the rubber rod 6463, which can continue to facilitate the surrounding plate to slide downward along the inner wall of the slide groove 5 without hindering the surrounding plate and the sealing plate 6461 from sliding downward due to the surface of the furnace box 3. At the same time, it also facilitates the continuous downward movement of the heat absorption equipment, that is, the surrounding mechanism 6 will not hinder the downward movement of the heat absorption equipment.

[0053] When the furnace body 4 has finished smelting the metal, the lifting mechanism 7 needs to drive the heat absorbing component 71 to move upward, and no longer press the upper surface of the surrounding mechanism 6, so that the upper part of the surrounding mechanism 6 can leak out. When the plug 73 is out of contact with the circular groove 65, the lower pressing plate 641 shrinks downward under the elasticity of the squeezing spring 642, and the sealing plate 6461 is reset downward under the elasticity of the pushing spring 645, so that the sealing plates 6461 on the front and rear sides of the furnace body 4 can be separated. During the process of the furnace body 4 being tilted, the smoke can flow upward directly from the middle of the two surrounding plates, and the surrounding of the surrounding plates will not affect the upstream flow of the smoke, so as to avoid the surrounding plates changing the flow path of the smoke. At the same time, the separation of the sealing plates and the telescopic plates on both sides of the furnace body will not hinder the tilting of the molten metal inside the furnace body.

[0054] The specific workflow is as follows:

[0055] In the initial state, the present invention drives the furnace to tilt through the motor 2 and the output shaft of the motor 2. During the process of melting the metal in the furnace, the lifting mechanism 7 can absorb the residual heat above the furnace body 4 through the heat absorbing component 71. The lifting component can adjust the height of the heat absorbing component 71 itself according to the temperature change of the furnace body 4. During the descent of the lifting component, it will touch the surrounding mechanism 6 and complete the basic sealing treatment of the space above and around the furnace body 4 with the surrounding mechanism 6 to prevent the smoke from escaping around the furnace body 4. At the same time, the lifting mechanism 7 can adjust its own movement according to the tilting rotation of the furnace body 4, so that the heat absorbing device can be located above the smoke exhaust of the furnace body 4 to a certain extent, which is convenient for the heat absorbing device to absorb the smoke.

[0056] The surrounding mechanism 6 can slide down along the inner wall of the chute 5 as the heat absorbing component 71 in the lifting component moves downward. The heat absorbing component 71 absorbs the smoke, and the heat exchanger 712 absorbs the residual heat in the smoke. The cleaning component 716 cleans the smoking pipe 713 in the heat absorbing component 71 to prevent stains from accumulating on the lower surface and inside of the smoking pipe 713. The collecting box 7165 collects the stains.
