[0049] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0050] Currently, in the field of primary steel slag treatment, membrane coolers are used to cool and recover the waste heat of granulated high-temperature steel slag due to their advantages of high cooling efficiency and relatively closed system, which makes it less likely to cause metal oxidation in the steel slag.

[0051] However, in actual operation, when the steel slag is discharged from the feed pipe into the cylinder of the membrane cooler, it directly impacts the inner wall of the cylinder, causing damage to the inner wall and thus shortening the service life of the membrane cooler. Therefore, how to reduce the damage of steel slag to the inner wall of the cooler cylinder and extend the service life of the membrane cooler has become an urgent technical problem to be solved.

[0052] In response, this utility model discloses a feeding device and a membrane cooler, which can avoid the direct impact of steel slag on the inner wall of the membrane cooler cylinder when the steel slag is discharged from the feeding pipe into the cylinder of the membrane cooler, thereby reducing the damage of steel slag to the inner wall of the cooling chamber, that is, reducing the damage of steel slag to the inner wall of the cooler drum, and thus extending the service life of the membrane cooler.

[0053] like Figure 1 As shown, this utility model discloses a feeding device 100, which includes a feeding pipe 11 and a buffer assembly 12. The feeding device 100 is applied to a membrane cooler 200, which includes a cooler body 21. The cooler body 21 has a cooling chamber and a feeding port communicating with the cooling chamber. The feeding pipe 11 is used to discharge steel slag into the cooling chamber of the cooler body 21 through the discharge port. The buffer assembly 12 is disposed at the discharge port of the feeding pipe 11, corresponding to the discharge port of the feeding pipe 11. The buffer assembly 12 is used to buffer the steel slag discharged from the discharge port of the feeding pipe 11.

[0054] In this embodiment, the feed pipe 11 is also provided with a feed port at its feeding end. The feed pipe 11 is connected to the discharge port of the equipment in the prior process through its feed port. The equipment in the prior process feeds the steel slag to be cooled into the feed pipe 11 through the feed port of the feed pipe 11.

[0055] Furthermore, the feed pipe 11 can be divided into three sections, with adjacent sections connected at a certain angle to each other, so that the cross-section of the feed pipe 11 is Z-shaped, that is, the feed pipe 11 has two corners, which can limit the flow rate of steel slag in the feed pipe 11 to a certain extent. At the same time, the materials used to construct both the feed pipe 11 and the buffer assembly 12 can be selected from high-temperature resistant materials.

[0056] Steel slag is conveyed from the feed inlet of feed pipe 11 to the discharge inlet of feed pipe 11, and discharged from feed pipe 11 through the discharge inlet, for example... Figure 1 In the middle A direction, the steel slag flows in the feed pipe 11. After being discharged from the feed pipe 11, the steel slag first impacts the buffer assembly 12 before contacting the inner wall of the cooling chamber of the cooler body 21, thus avoiding direct impact of the steel slag on the inner wall of the cooler body 21.

[0057] Furthermore, the material of the buffer component 12 can also be an impact-resistant material. Through the buffer component 12's buffering of the impact of steel slag, the buffer component 12 can also play a certain role in crushing large steel slag particles. Since the small steel slag particles formed after crushing have a lower damage ability to the inner wall of the cooler body 21, the damage of steel slag to the inner wall of the cooler body 21 can be further reduced.

[0058] As can be seen, the feeding device 100 of this utility model can buffer the steel slag discharged from the discharge port of the feeding pipe 11 through the buffer component 12, avoiding the direct impact of the steel slag on the inner wall of the cooler body 21. At the same time, it can also play a certain role in crushing large steel slag particles, reducing the damage of steel slag to the inner wall of the cooling chamber of the cooler body 21, thereby extending the service life of the membrane cooler 200.

[0059] like Figure 1 As shown, in an optional embodiment, the buffer assembly 12 includes: a buffer baffle 122 and at least two connecting rods 121, each connecting rod 121 having a first end and a second end opposite to each other, the first end of the connecting rod 121 being connected to the discharge end of the feed pipe 11; the buffer baffle 122 being connected to the second end of the connecting rod 121, the buffer baffle being correspondingly provided with respect to the discharge port of the feed pipe 11, and the buffer baffle 122 being used to buffer the steel slag discharged from the discharge port of the feed pipe 11.

[0060] In this optional embodiment, the buffer baffle 122 has a buffer surface, which faces the discharge port of the feed tube 11. The first end of each connecting rod 121 is connected to the discharge end of the feed tube 11, and the connection point between the first end of the connecting rod 121 and the feed tube 11 is close to the discharge port of the feed tube 11. The second end of each connecting rod 121 is connected to the buffer baffle 122. Preferably, the connection points of each connecting rod 121 and the feed tube 11 are symmetrically arranged about the central axis of the discharge port of the feed tube 11 to ensure uniform force distribution at each connection point. The number of connecting rods 121 can be adjusted according to actual needs.

[0061] Further, through the connection between the feeding pipe body 11 and the connecting rod 121 and the buffer baffle 122, a distance is formed between the buffer baffle 122 and the discharge port of the feeding pipe body 11, so as to ensure that the steel slag has enough space to fall into the cooling cavity of the cooling machine body 21 after impacting the buffer baffle 122.

[0062] It can be seen that, in the optional embodiment, the buffer baffle 122 is fixed by the connecting rod 121, so that the buffer baffle 122 is not easy to fall off after being impacted by the steel slag. In addition, a distance is formed between the buffer baffle 122 and the discharge port of the feeding pipe body 11, so as to ensure that the steel slag has enough space to fall into the cooling cavity of the cooling machine body 21 after impacting the buffer baffle 122.

[0063] As shown in FIG. 1, Figure 2 In an optional embodiment, the buffer baffle 122 includes a buffer baffle body 1221 and at least two first rotating parts 1222. The buffer baffle body 1221 has a buffer surface, and the buffer baffle body 1221 is used for buffering the steel slag discharged from the discharge port of the feeding pipe body 11 through the buffer surface. Each first rotating part 1222 is arranged at the edge of the buffer surface of the buffer baffle body 1221, and each first rotating part 1222 is connected with the second end of a corresponding connecting rod 121. The buffer baffle body 1221 can rotate around the rotating shaft formed by each first rotating part 1222 as the rotating center.

[0064] In the optional embodiment, the number of the first rotating parts 1222 is the same as the number of the connecting rods 121, and each first rotating part 1222 is connected with the second end of a corresponding connecting rod 121. The buffer surface of the buffer baffle body 1221 is arranged towards the discharge port of the feeding pipe body 11, and the buffer baffle body 1221 can rotate around the rotating shaft formed by each first rotating part 1222 as the rotating center, so as to adjust the angle between the buffer baffle body 1221 and the discharge port of the feeding pipe body 11, thereby realizing the adjustment of the buffering effect of the steel slag.

[0065] Preferably, the number of the first rotating parts 1222 and the connecting rods 121 is even, and each first rotating part 1222 is symmetrically arranged with the central axis of the buffer baffle body 1221, so as to ensure that the connecting fulcrum between each first rotating part 1222 and the corresponding connecting rod 121 is uniformly stressed.

[0066] Further, in addition to the buffer baffle body 1221 being a rectangular baffle as shown in FIG. 1, Figure 2 the buffer baffle body 1221 can also be selected as a baffle of other shapes according to requirements, such as a disc-shaped baffle.

[0067] Preferably, the buffer baffle body 1221 can be selected as aFigure 3 The conical baffle shown has its inner cone acting as a buffer to cushion the steel slag. Because the inner cone of the baffle has a funnel-like structure, it can temporarily retain the steel slag within this funnel structure for a short time, thereby mitigating the splashing effect caused by the steel slag impacting the buffer baffle 122 at excessive speed. The temporarily retained steel slag can flow from the inner cone of the baffle to the inner wall of the cooling chamber of the cooler body 21 at a lower speed. Therefore, choosing a conical baffle body 1221 further reduces the damage to the inner wall of the cooling chamber of the cooler body 21 caused by steel slag, thus further extending the service life of the membrane cooler 200.

[0068] like Figure 2 As shown, in an optional embodiment, the feeding device 100 further includes at least two second rotating parts 13, each second rotating part 13 being disposed on the outer surface of the feeding end of the feeding tube 11, each second rotating part 13 being connected to the first end of a corresponding connecting rod 121, and the connecting rod 121 being able to rotate about the rotating axis formed by each second rotating part 13 as the rotation center.

[0069] In this optional embodiment, the number of second rotating parts 13 is the same as the number of connecting rods 121, and each second rotating part 13 is connected to the second end of its corresponding connecting rod 121. Each second rotating part 13 is connected to the discharge end of the feed pipe 11, and the connection point between the first end of the connecting rod 121 and the feed pipe 11 is close to the discharge port of the feed pipe 11. The second end of each connecting rod 121 is connected to the buffer baffle 122. Each connecting rod 121 can rotate around the rotation axis formed by each second rotating part 13 as the rotation center. By rotating and moving each connecting rod 121, the angle between the buffer baffle body 1221 and the discharge port of the feed pipe 11 is adjusted, thereby adjusting the buffering effect of the steel slag.

[0070] Preferably, an even number of second rotating parts 13 and connecting rods 121 are arranged, and each second rotating part 13 is symmetrically arranged on the outer surface of the feed pipe body 11 with respect to the center of the feed inlet, thereby ensuring that the connection fulcrum between each second rotating part 13 and the corresponding connecting rod 121 is subjected to uniform force. For example, refer to... Figure 4 Two second rotating parts 13 are configured, with the Y-axis being the central axis of symmetry of the feed pipe 11 discharge port and the X-axis being the rotation axis formed by the two second rotating parts 13.

[0071] In an optional embodiment, the feeding device 100 further comprises a rotating driving motor and a motor controller. The driving end of the rotating driving motor is connected with a corresponding second rotating part 13, and the motor controller is electrically connected with the rotating driving motor, and the motor controller is used to control the rotating driving motor to rotate, so as to drive the connecting rod 121 to rotate around the rotating shaft formed by the corresponding second rotating part 13.

[0072] In the optional embodiment, each second rotating part 13 is provided with a corresponding rotating driving motor, and each rotating driving motor is connected with the corresponding second rotating part 13 through the driving end thereof. The motor controller is electrically connected with each rotating driving motor respectively, and the motor controller can control the rotating parameters of the rotating driving motor, such as the rotating direction and the rotating angle. The motor controller drives the connecting rod 121 to rotate around the rotating shaft formed by the corresponding second rotating part 13 by controlling the rotating parameters of the rotating driving motor, and then adjusts the angle between the buffer baffle 122 and the discharge port of the feeding pipe body 11.

[0073] It can be seen that in the optional embodiment, the angle between the buffer baffle 122 and the discharge port of the feeding pipe body 11 can also be adjusted by controlling the rotating parameters of the rotating driving motor through the motor controller, that is, the operator can adjust the angle between the buffer baffle 122 and the discharge port in real time according to the current discharging speed of the steel slag, so as to better control the buffering effect on the steel slag.

[0074] As shown in FIG. 1, Figure 1 In an optional embodiment, the feeding pipe body 11 comprises an upper feeding pipe body and a lower feeding pipe body, and the feeding device 100 further comprises a corrugated compensator 14. The corrugated compensator 14 has opposite two ends, and the two ends of the corrugated compensator 14 are connected with the upper feeding pipe body and the lower feeding pipe body respectively, so that the cavities of the upper feeding pipe body and the lower feeding pipe body are communicated, and the corrugated compensator 14 is used to compensate the deformation of the upper feeding pipe body and the lower feeding pipe body.

[0075] In the optional embodiment, the upper feeding pipe body and the lower feeding pipe body can each be further divided into two sections, and the two sections of the upper feeding pipe body are connected with each other at a certain angle, and the two sections of the lower feeding pipe body are also connected with each other at a certain angle. The upper feeding pipe body is provided with an upper feeding port at the upper feeding end thereof, and the lower feeding pipe body is provided with a lower discharge port at the lower discharge end thereof. The arrangement and the function of the upper feeding port and the lower discharge port can be referred to the specific description of the above embodiments.

[0076] The feeding section and the unloading section are connected as a single feed pipe 11 by a corrugated compensator 14, giving the feed pipe 11 a Z-shaped cross-section. The corrugated compensator 14 has an internal cavity, allowing communication between the cavities of the feeding and unloading sections. The corrugated compensator 14 also has a deformation function; its placement between the feeding and unloading sections compensates for the deformation of the entire feed pipe 11.

[0077] like Figure 1 As shown, in an optional embodiment, the flow rate control end of the feed pipe 11 is provided with a flow rate control opening, and the flow rate control end is close to the feed port of the feed pipe 11; the feed device 100 also includes a high temperature gate valve 15, which seals or opens the flow rate control opening, and the high temperature gate valve 15 is used to control the flow rate of steel slag in the feed pipe 11.

[0078] In this optional embodiment, the high-temperature gate valve 15 can be installed in the feeding section pipe or the discharging section pipe, for example, referring to... Figure 1 The high-temperature gate valve 15 is installed at the feeding section of the pipe. It is understood that the specific location of the high-temperature gate valve 15 can be adjusted according to actual needs. The high-temperature gate valve 15 controls the flow rate of the steel slag in the feeding pipe by sealing or opening the flow rate control opening, thus controlling the speed at which the steel slag is discharged from the discharge port. Combined with the adjustment of the angle between the buffer baffle 122 and the discharge port in the optional embodiment described above, the buffering effect of the steel slag can be better controlled.

[0079] In one specific embodiment, the feed tube 11 is made of steel plate with a thickness of 8 mm or more, thereby improving the wear resistance of the feed tube.

[0080] like Figure 1 As shown, this utility model also discloses a membrane cooler 200, which includes a cooler body 21 and a feeding device 100 described in the above embodiments of this utility model. The cooler body 21 has a cooling chamber and a feeding port communicating with the cooling chamber; the discharge port of the feeding pipe 11 in the feeding device 100 is connected to the cooling chamber of the cooler body 21 through the feeding port of the cooler body 21, and the feeding pipe 11 is used to discharge steel slag into the cooling chamber of the cooler body 21 through the discharge port; wherein, the cooler body 21 is used to cool the steel slag discharged into the cooling chamber.

[0081] It can be seen that in the embodiment, the membrane cooler 200 can buffer the steel slag discharged from the discharge opening of the feeding pipe body 11 by the buffer assembly 12 in the feeding device 100, avoid direct impact of the steel slag on the inner wall of the cooler body 21, and also play a certain crushing effect on large steel slag, thereby reducing damage of the steel slag to the inner wall of the cooler body 21, and prolonging the service life of the membrane cooler 200.

[0082] As shown in Figure 1 and Figure 5 , in an optional embodiment, the cooler body 21 comprises a cooling cylinder body 211 and a cooling liquid containing pipe 212, the cooling cylinder body 211 is internally provided with a cooling cavity, the feeding end of the cooling cylinder body 211 is provided with a feeding opening in communication with the cooling cavity, and the cooling liquid containing pipe 212 is arranged on the outer surface of the cooling cylinder body 211 along the axial direction of the cooling cylinder body 211, and is used for containing cooling liquid.

[0083] In the optional embodiment, referring to Figure 1 , the cooling cylinder body 211 is further provided with a discharge opening P arranged opposite to the feeding opening of the cooling cylinder body 211, and the steel slag in the cooling cavity can be discharged from the cooling cylinder body 211 through the discharge opening P.

[0084] Referring to Figure 5 , a plurality of cooling liquid containing pipes 212 can be arranged, all the cooling liquid containing pipes 212 are arranged on the outer surface of the cooling cylinder body 211 along the axial direction of the cooling cylinder body 211, and all the cooling liquid containing pipes 212 are uniformly arranged on the outer surface of the cooling cylinder body 211 with a certain distance between adjacent two cooling liquid containing pipes 212. The cooling liquid containing pipe 212 has a liquid inlet and a liquid outlet, cooling liquid can be introduced into the cooling liquid containing pipe 212 through the liquid inlet, and the cooling liquid in the cooling liquid containing pipe 212 can be discharged through the liquid outlet. It can be understood that the number of the cooling liquid containing pipes 212 depends on the size of the cooling cylinder body 211 and the required cooling effect, and the specific number can be adjusted according to actual needs.

[0085] It can be seen that the membrane cooler 200 of the optional embodiment can cool the steel slag in the cooling cavity of the cooling cylinder body 211 by arranging the cooling liquid containing pipe 212 on the outer surface of the cooling cylinder body 211.

[0086] As shown in Figure 1 , Figure 5 and Figure 6As shown, in an optional embodiment, the film cooler 200 further comprises a spiral guide plate 22 and a rotation control device 23.
