[0051] The embodiment part will be combined with the drawings of the specification Figure 1 to the drawings Figure 13 The core heat exchange structure of the high-temperature steel slag cooling rotary table is described in detail.

[0052] Reference Figure 1 and Figure 2 , Figure 1 and Figure 2 respectively show the cross-sectional views of the two different structures of the screw cone heat exchange cooler. Both of the two structures of the cooler are within the protection scope of the utility model.

[0053] The core mechanism of the cooler is a rotary table 110 with a spiral material discharge channel 120, that is, the structural feature of the rotary table is the core innovation of the utility model. The spiral material discharge channel 120 is formed in the following way: the rotary table 110 is a conical profile component, and the high point at the center position of the rotary table is the material inlet end 111, and the low point at the circumferential periphery of the rotary table is the material discharge end 112, and the spiral wall 130 is formed between the material inlet end and the material discharge end to form the spiral material discharge channel 120 arranged from top to bottom, and the spiral material discharge channel 120 spirals from the oblique upper side of the rotary table downward until reaching the edge position of the rotary table 110.

[0054] The spiral wall 130 described above can be counterclockwise spiral or clockwise spiral.

[0055] Most preferably, the spiral material discharge channel 120 described above is designed with equal width.

[0056] The spiral wall 130 can be a solid alloy steel rib or a water-cooled pipe assembly.

[0057] As a specific structure style, reference Figure 6 and Figure 7In this embodiment, the spiral wall 130 is formed by splicing together multiple independent spiral heat exchange wall units 131, and the splicing seam 132 between two spiral heat exchange wall units 131 is as small as possible, or the splicing seam is filled, for example, by using mud seal. When the splicing seam is small enough, mud seal is not required.

[0058] Furthermore, the height of the spiral walls on both sides of the aforementioned spiral discharge channel 120 gradually decreases from the feed end to the discharge end 112, as shown in the reference. Figure 1 , Figure 2 As shown in the diagram, the height of the spiral heat exchange wall unit 131 located in the high-temperature zone is significantly greater than the height of the spiral heat exchange wall unit 131 located in the low-temperature zone. This design is beneficial for forming sufficient heat exchange paths and obtaining a sufficient amount of supersaturated high-temperature water.

[0059] As described above, the spiral wall 130 is formed by splicing together multiple independent spiral heat exchange wall units 131, as shown in the reference. Figure 6 Each spiral heat exchange wall unit 131 is composed of water-cooled pipes 13 arranged side-by-side in the height direction. For example, multiple water-cooled pipes are welded together to form a thick, wall-like spiral heat exchange wall unit 131. That is, the spiral wall is directly manufactured using water-cooled pipes, resulting in a hollow structure with heat exchange function. Each spiral heat exchange wall unit 131 is arranged 360 degrees, with no closed ends, and a small radius at the starting end and a large radius at the ending end, forming a pitch of the spiral wall. By introducing desalination and softening water medium into the water-cooled pipes 13 of the spiral heat exchange wall unit 131, and ensuring that the desalination and softening water medium is in a moderately flowing state under the action of a booster pump, and by ensuring direct contact between the high-temperature steel slag in the spiral discharge channel 120 and the outer wall of the spiral water-cooled pipe 132, it is easy to understand that the desalination and softening water medium in the multiple water-cooled pipes 13 of each set of spiral heat exchange wall units is basically in an isothermal state, thus realizing a hollow wall-like water-cooled wall structure. This process achieves heat exchange between high-temperature steel slag and the desalination softening water medium. The heat exchange lowers the temperature of the high-temperature steel slag and raises the temperature of the desalination softening water medium, thus converting the sensible heat of the high-temperature steel slag into high-temperature water (the desalination softening water medium) at a certain pressure and temperature. Finally, a high-temperature water-cooling circulation system is used to flash-evaporate the high-temperature, high-pressure hot water to produce saturated steam of a certain quality, resulting in high-quality saturated steam for industrial production. Alternatively, a low-temperature water-cooling circulation system can be used to produce low-quality hot water for domestic or industrial use.

[0060] refer to Figure 5The spiral heat exchange wall units 131 are multiple and form an approximately continuous spiral discharging channel 120 in abutting manner, which is the advancing path of high-temperature steel slag, i.e. the high-temperature steel slag advances in the spiral discharging channel 120. Through the design of the spiral structure, the high-temperature steel slag has a long enough heat exchange path, which is of positive significance for ensuring the heat exchange effect and can realize the miniaturization and stereoscopic of the equipment.

[0061] Further elaboration, the heat exchange area in the present screw cone heat exchange cooler is divided into high-temperature area A and low-temperature area B, for the convenience of distinguishing and indicating, a boundary line L is given in Figure 5 , which does not exist in the actual space. The high-temperature area A is a circular annular area near the feeding end 111, and the low-temperature area B is a circular annular area near the discharging end 112. The spiral water cooling pipes in the two areas form independent cooling pipe systems, i.e. independent closed loops formed by different booster pumps and pipes. The water cooling pipes in the high-temperature area are connected to the high-temperature slag water cooling system through pipes, and the water cooling pipes in the low-temperature area are connected to the low-temperature slag water cooling system through pipes. Through the grading method, different supersaturated high-temperature hot water and ordinary hot water are obtained. The working principles of each area are described in more detail below:

[0062] The high-temperature area A of the screw cone heat exchange cooler cools the high-temperature steel slag from above 1000℃ to about 300℃, while obtaining high-pressure high-temperature supersaturated hot water with a pressure of 2.0MPa and a temperature of 200℃. This goal is achieved through the heat exchange of the spiral water cooling pipes in this area. The desalted softened water medium in the water cooling pipes in this area flows in the opposite direction. If the water cooling pipes in this area are arranged in the clockwise direction, the desalted softened water medium in the pipes is arranged in the counterclockwise direction, i.e. the flow direction of the desalted softened water medium is opposite to the flow direction of the high-temperature steel slag in the spiral discharging channel 120, so that the best heat exchange effect can be obtained. This heat exchange effect not only reflects in the heat exchange efficiency (stronger), but also reflects in the outlet temperature of the high-temperature high-pressure supersaturated hot water (higher). For reference Figure 3The high-temperature water produced by heat exchange enters the flash tank 300, and the pressure reduction flash evaporation produces steam. The operating pressure of the flash tank is 0.8 MPa, and the saturated steam and saturated condensate produced at 175.4°C. The saturated steam produced is used through the branch into the steam pipe network, and the saturated condensate (desalted softened water) is returned to the screw cone heat exchange cooler through the booster circulating pump to exchange heat with the steel slag again. The saturated condensate is heated to 200°C again in the heat exchange pipe 13 and then enters the flash tank to produce steam. This cycle produces stable saturated steam. At the same time, the water quantity after flashing needs to be continuously supplemented to maintain overall heat balance and material balance. The saturated steam produced in the high-temperature area is high-quality steam.

[0063] The low-temperature area B of the screw cone heat exchange cooler further cools the medium-high temperature steel slag at about 300°C to low-temperature steel slag below 120°C, while producing hot water. The temperature of the hot water obtained by heat exchange in this low-temperature area B is theoretically higher than 60°C. Referring to Figure 4 The hot water can be used to heat water for living or production, such as warm water for living and production in the factory area, to meet the requirements of subsequent transportation and storage. If there is no need to store hot water, the produced hot water can be cooled to below 45°C through the cooling tower 410, and then circulated to the low-temperature area through the circulating pump for cyclic heat exchange, forming an independent system. The water system adopts a closed cycle through the cooling tower.

[0064] The discharge end 112 of the screw discharge channel 120 is located on one side of the outer periphery of the rotating disc. A material collecting groove 140 is arranged in a ring shape on the outer side of the rotating disc. The material collecting groove 140 is used to collect the steel slag material discharged from the outer periphery of the rotating disc, and a discharge port 141 is formed at a certain position of the material collecting groove 140. A plurality of scraping plates 150 are fixed on the periphery of the edge of the rotating disc 110. The scraping plates are welded or bolted to the edge of the rotating disc 110. The scraping plates 150 are located in the material collecting groove and scrape the steel slag material in the material collecting groove. During the rotation of the rotating disc 110, the scraping plates 150 slide along the material collecting groove, scraping the steel slag in the material collecting groove. During the scraping process, the steel slag moves along the material collecting groove and is discharged from the discharge port 141 of the material collecting groove.

[0065] Further, a transfer machine (such as a transfer car) can be arranged outside the discharge port 141 to transfer the cooled steel slag.

[0066] The high-temperature water cooling circulation system described above is composed of a flash tank 300, a circulating pump, a pipeline, a valve, an instrument, and a PLC intelligent control module. The composition drawing is referred to Figure 3 The desalted softened water medium is stored in the water supplement tank.

[0067] The low-temperature water cooling circulation system described above is composed of a tap water pipe, a booster pump, a plate heat exchanger 400, a cooling tower 410, pipes, valves, instruments, and a PLC intelligent control module, as shown in Figure 4 .

[0068] Figure 1 and Figure 2 The screw cone heat exchange cooler in the embodiments shown in the above can realize the cooling of high-temperature steel slag and the heating of water medium through heat conduction between the water medium in the water cooling pipe 132 and the high-temperature steel slag outside the pipe.

[0069] The heat exchange space in the screw cone heat exchange cooler in the embodiments shown in the above can realize staged heat exchange through segmented heat exchange, and each circumference can be a heat exchange unit. The high-temperature zone can generate high-quality supersaturated hot water and supersaturated steam (heat recovery by-products), and a high-quality steam heat source can be directly obtained. The high-quality supersaturated steam can be directly used for production. At the same time, low-quality hot water can be obtained in the low-temperature zone.

[0070] The rotating disc described above is dynamically rotatable, and the specific structure of the rotating driving structure is as follows:

[0071] Referring to Figure 1 , Figure 11 and Figure 12 , the rotating disc 110 body is a high-temperature-resistant structure formed by a steel plate 101 and refractory bricks 102 laid on the surface of the steel plate. Specifically, the steel plate is bent to form a conical profile, which is a core component of the device. The conical body formed by the steel plate is placed vertically, and then an I-beam steel frame 103 is welded below the steel plate to form a support structure. The bottom of the I-beam steel frame is provided with four groups of concentrically arranged tracks 104 and metal chains 105. The metal chains are installed on the side of the bottom of the I-beam steel frame and surround the side of the I-beam steel frame. A ground wheel assembly 106 is installed on the foundation below the tracks for supporting the I-beam steel frame. At least one group of ground wheel assemblies has a restraining function, so that the I-beam steel frame can rotate concentrically along the tracks and the ground wheels. At least one group of chain drive assemblies 107 is installed on the foundation. Specifically, the chain drive assembly includes a drive motor, a speed reducer, and a metal sprocket. In the embodiment, the drive motor and the speed reducer are vertically installed, and the metal sprocket is horizontally installed on the power output shaft of the speed reducer. The metal sprocket engages with the metal chain and drives the rotation of the I-beam steel frame. The I-beam steel frame drives the rotation of the rotating disc during rotation. Therefore, the chain drive assembly 107 is a power driving module for rotation. A side stop assembly 108 is arranged on the inner annular edge of the steel frame for horizontal limiting.

[0072] The driving motor is preferably a speed-regulating motor, so that the rotating speed of the rotating disc can be adjusted, the advancing speed of the steel slag can be adjusted, the cooling time can be controlled, and the temperature of the discharged slag can be controlled.

[0073] The power driving module can also have other forms, such as driving through a gear ring transmission or using a belt transmission, which will not be described one by one here, and all are within the implementation range of the utility model.

[0074] Meanwhile, the aggregate groove 140 is used for collecting the steel slag from the rotating disc during the rotation of the rotating disc, is a component for temporarily storing the steel slag, and realizes the orderly discharge of the cooled steel slag.

[0075] Further, a cover body 200 is fixedly installed above the rotating disc through a steel structure 210, the cover body also has a conical profile, an equidistant conical space 220 is formed between the cover body and the rotating disc, the space is also a high-temperature and high-heat space, and the air in the internal space is in a relatively static state, which can effectively avoid the oxidation of the steel slag during the cooling process.

[0076] In the principle of facilitating maintenance, the heat exchange space should have sufficient space.

[0077] Further, the cover body 200 is a composite structure composed of a metal shell and internal refractory bricks, the metal shell has the advantage of easy forming, and the refractory bricks have the advantage of high-temperature resistance.

[0078] Further, it is determined according to needs whether to set a heat preservation layer, such as rock wool, on the outside of the cover body.

[0079] Further, it is determined according to needs whether to lay a metal pipe on the inner surface of the cover body 200 and connect the metal pipe to a water cooling system, so as to cool the cover body 200 through the metal pipe heat exchange mode and form an independent water cooling facility.

[0080] The physical center position of the cover body 200 described above is the feeding port 230, that is, the feeding port of the high-temperature steel slag, and the physical center position of the rotating disc 110 is below the feeding port, so as to facilitate the speed reduction of the steel slag and reduce the vertical impact on the rotating disc, a conical distribution protrusion 240 protruding upward is arranged at the center position of the rotating disc corresponding to the feeding port, the conical distribution protrusion faces the feeding port of the cover body, when the high-temperature steel slag falls downward under the action of gravity, the high-speed falling steel slag collides with the conical distribution protrusion and rebounds laterally, and finally falls into the rotating disc, and Figure 1 .

[0081] Further, a spiral protrusion 241 is arranged in the conical distribution protrusion 240 described above, for controlling the distribution speed, and Figure 2 .

[0082] Figure 1 and Figure 2 , respectively, two different styles of conical distribution protrusions are shown.

[0083] Further, the surface of the conical distribution protrusion 240 is a refractory material layer. A wind distribution pipe is arranged at the lower side of the conical distribution protrusion, and a wind distribution nozzle is arranged at the upper side of the conical distribution protrusion 240. The wind distribution pipe is connected to the air blower through a rotary joint and blows cold air to the upper inlet of the conical distribution protrusion by air blowing, that is, the wind distribution system cools the surface of the steel slag during the falling process. In this process, only the surface of the high-temperature steel slag at the moment of falling is cooled, thereby solving the problem of adhesion of the steel slag during the falling process and ensuring the uniform and effective distribution of the steel slag.

[0084] Further, the lower edge of the cover body 200 is attached to the outer edge of the material collecting groove of the rotating disc, and a refractory material is arranged therebetween to form a dynamic seal, for example, a heat-insulating rock wool. Through this structure, a detachable assembly type connection is formed between the cover body and the material collecting groove, which meets the maintenance and needs.

[0085] Further, an access door is arranged at a certain position of the cover body 200, which can be quickly opened and maintained through opening and closing. This structure facilitates the rapid maintenance of the equipment.

[0086] Regarding the innovation of the arrangement of the water cooling pipe in the present screw cone heat exchange cooler:

[0087] Pattern one, refer to Figure 6 and Figure 7 The spiral lofting is performed on the conical surface of the rotating disc 110 from the feeding end to the discharging end. The so-called lofting refers to drawing on the conical surface to form the fixed points of the spiral water cooling pipe. The spiral lofting development drawing in this pattern is a single spiral. After lofting, the water cooling pipe is made of metal wear-resistant pipe, and further, the spiral heat exchange wall unit 131 is made. The spiral heat exchange wall unit 131 is designed for 360 degrees. Multiple spiral heat exchange wall units are formed by welding multiple water cooling pipes in the height direction, which are in the form of three-dimensional partition plates. Further, to enhance the fixing strength of the spiral heat exchange wall unit 131 and the diameter of the rotating disc, a fixed rib plate (not shown in the figure) is arranged between the rotating disc and the reinforced spiral heat exchange wall unit. The fixed rib plate supports the reinforced spiral heat exchange wall unit from below in the direction of gravity, which can effectively improve the support of the steel slag particles and avoid deformation of the reinforced spiral heat exchange wall unit. Figure 6

[0088] ​The high point of each enhanced spiral heat exchange wall unit 131 is connected by a vertical first water feeding branch pipe 1311, the first water feeding branch pipes of multiple enhanced spiral heat exchange wall units are secondarily connected and gathered to a second water feeding branch pipe 1312, the second water feeding branch pipe is preferably horizontally arranged, the horizontally arranged second water feeding branch pipe is connected to a third water feeding branch pipe 1313 through a tee joint, and the third water feeding branch pipe is connected to a rotary joint 1314 outside.

[0089] Similarly, the low point of each enhanced spiral heat exchange wall unit 131 is connected by a vertical first water returning branch pipe 1321, the first water returning branch pipes of multiple enhanced spiral heat exchange wall units are secondarily connected and gathered to a second water returning branch pipe 1322, the second water returning branch pipe is preferably horizontally arranged, the horizontally arranged second water returning branch pipe is connected to a third water returning branch pipe 1323 through a tee joint, and the third water returning branch pipe is connected to the rotary joint 1314 outside.

[0090] The rotary joint 1314 is located at the position of the rotation axis of the rotating disc.

[0091] The naming of the branch pipes is performed according to the direction of water flow, and in the working state, the water temperature of the water feeding is obviously lower than that of the water returning.

[0092] The rotating disc is paved with refractory bricks, and a pushing channel of steel slag material is formed between the rotating disc and the spiral pipes on both sides, when the rotating disc rotates clockwise, the internal steel slag material slides downward under the action of the gravity rotating disc driving force, and the sliding speed of the steel slag is controllable, specifically, the sliding pushing speed of the steel slag can be regulated by controlling the rotating speed of the rotating disc.

[0093] Further, the rotating disc driving force is converted from constant speed driving to periodic motion with acceleration and deceleration combination, the spiral sliding speed of the internal steel slag can be more quickly controlled, whether the uniform speed or the pulse type acceleration and deceleration motion is within the protection scope of the utility model.

[0094] Pattern two

[0095] Reference Figure 8On the basis of style one, the following is added: the spiral auxiliary water cooling pipe 133 is arranged in the rotating disc, the spiral auxiliary water cooling pipe 133 is also a 360-degree spiral, which is arranged on the upper surface of the rotating disc, specifically, the water cooling pipe is fixedly installed on the spiral steel slag pushing channel bottom plate, for the convenience of distinguishing from example one, the water cooling pipe is marked as auxiliary water cooling pipe 133, for the convenience of distinguishing from the spiral heat exchange wall unit, it is called spiral heat exchange bottom, the auxiliary water cooling pipe 133 is also arranged in parallel, and the water inlet end and the water return end of the auxiliary water cooling pipe are also communicated with the first water inlet branch pipe and the first water return branch pipe. In this way, the steel slag directly contacts the bottom and side of the spiral conveying channel, and the soft water medium in the water cooling pipe is subjected to heat exchange. Compared with style one, this style increases the number of water cooling pipes in the spiral conveying channel contact area per unit area, so the heat exchange effect is better. Combined with the rotating action of the rotating disc described above, the rotating disc can rotate at a higher speed, shortening the heat exchange path, and achieving a more compact device under the same heat exchange effect.

[0096] Style three

[0097] Reference Figure 9 The structure of the present style is as follows: first, the spiral walls on both sides of the spiral discharge channel 120 are not provided with water cooling pipes, but are provided with traditional high-temperature-resistant solid alloy partitions 134, that is, unlike style two, in the present embodiment, the two sides forming the spiral discharge channel 120 are alloy partitions, which are solid structures and do not have water cooling pipes inside. The spiral discharge channel 120 is formed by the spiral partitions, such as the slopes welded to the rotating disc 110. The channel is also a high-temperature steel slag discharge channel. The spiral water cooling pipe is arranged in the spiral discharge channel 120 of the rotating disc, for the convenience of distinguishing from example one, the water cooling pipe is marked as auxiliary water cooling pipe 133. Essentially, the auxiliary water cooling pipe has the same material and specifications as the water cooling pipe of example one. The auxiliary water cooling pipe is also a 360-degree spiral, which is arranged on the upper surface of the rotating disc, specifically, the auxiliary water cooling pipe is fixedly installed on the bottom plate of the spiral discharge channel, which is called a spiral heat exchange bottom, the auxiliary water cooling pipe 133 is also arranged in parallel, and the water inlet end and the water return end of the auxiliary water cooling pipe are also communicated with the first water inlet branch pipe and the first water return branch pipe. In this way, the spiral heat exchange bottom of the spiral discharge channel 120 is directly contacted with the steel slag, and the soft water medium in the water cooling pipe is subjected to heat exchange. This way only sets water cooling pipes on the slope bottom plate of the rotating disc, and the dense arrangement can also play a role in heat exchange.

[0098] Style four

[0099] Reference Figure 10On the basis of the third mode, a water cooling pipe is arranged on the inner wall of the alloy partition plate 134, for the convenience of distinguishing from the first mode, the water cooling pipe is marked as a spiral water cooling pipe 135, the spiral water cooling pipe 135 is arranged in parallel with the auxiliary water cooling pipe 133, so that the spiral water cooling pipe 135 and the auxiliary water cooling pipe 133 form water cooling pipes on the surface of the spiral discharging channel 120, wherein the water inlet end and the water return end of the spiral water cooling pipe 135 and the auxiliary water cooling pipe 133 are also communicated with the first water inlet branch pipe and the first water return branch pipe. In this way, the steel slag on the spiral heat exchange bottom of the spiral discharging channel 120 and the inner wall of the partition plate is subjected to heat exchange, and the heat exchange area is increased.

[0100] The above four modes disclose the combination mode of the water cooling pipe and the rotating disc, especially the four cases of the water cooling pipe being used as the spiral wall and the heat exchange bottom, which are all within the protection scope of the present application.

[0101] Of course, the spiral wall and the partition plate are only arranged in the single spiral structure, and can also be arranged in the double spiral or even triple spiral, that is, two or three spiral discharging channels 120 are formed, which only increases the implementation cost compared with the single spiral structure, and is within the protection scope of the present application, and reasonable protection is requested.

[0102] Further, the water cooling pipe, the auxiliary water cooling pipe and the spiral water cooling pipe are metal pipes with a unified specification. Meanwhile, a wear-resistant layer such as a ceramic layer, a wear-resistant plating layer or the like is arranged on the surface of the water cooling pipe, the auxiliary water cooling pipe and the spiral water cooling pipe, so as to improve the wear resistance and avoid early wear.

[0103] The above-described embodiments are only used to describe the preferred embodiments of the present application, and do not limit the scope of the present application, and various modifications and improvements of the present application made by those skilled in the art without departing from the design spirit of the present application shall fall within the protection scope of the present application defined by the claims.
