Description

Technical Field

[0001] The present invention relates to the field of charging of calcining furnaces, and particularly to an efficient charging and distributing structure for synthesizing zeolite from blast furnace slag in an iron and steel blast furnace Background Art

[0002] When synthesizing zeolite from blast furnace slag, since there are impurities in some zeolites, calcination is required first. The feeding and distributing equipment is auxiliary equipment for the calcining furnace;

[0004] This patent feeds the material into the lower calcining furnace by means of self - weight. This method will cause the material to pile up at the same position in the calcining furnace, resulting in uneven combustion and adhesion. If it is a rotary drum calcining furnace, even if the material is dispersed by rolling, when the material enters the calcining furnace, it is instantly heated, which will cause the material to adhere. Even if the calcining furnace rolls, it is very difficult to disperse the material. Summary of the Invention

Detailed Description of the Invention

[0027] The following description is merely exemplary in nature and is not intended to limit the present disclosure, its application, or uses. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the embodiments of the present disclosure. Specific parts in a specific drawing may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure. Embodiment

[0028] Refer to Figure 1 and Figure 2 As shown in the figures, the high-efficiency calcination furnace feeding and cloth-feeding structure for steel blast furnace slag synthetic zeolite includes a feeding hopper 2 and a support platform 5. The feeding hopper 2 is fixed on the support platform 5. The feeding hopper 2 is used to store materials, such as blast furnace slag. A dividing wheel 21 is rotatably connected inside the feeding hopper 2. Compartments are evenly arranged on the outer surface of the dividing wheel 21 for storing materials. By rotating the dividing wheel 21, the dividing wheel 21 catches the materials and discharges them from the bottom after reversing. A sealing cover 22 is fixed at the bottom of the feeding hopper 2, and through holes are formed on the outer surface of the sealing cover 22 for the materials to pass through.

[0029] Furthermore, refer to Figure 1 and Figure 2As shown, a feeding mechanism 1 is assembled at the bottom of the hopper 2. The feeding mechanism 1 is used for feeding and distributing materials. The feeding mechanism 1 includes a distributing box 11, a feeding wheel 12 and a motor 14. The distributing box 11 is rotatably connected to the support table 5 and the cover 22 respectively. The distributing box 11 is used for distributing materials by controlling the feeding angle through rotation. The feeding wheel 12 is rotatably connected inside the distributing box 11. The feeding wheel 12 is used for increasing the feeding force by using centrifugal force. The motor 14 is fixed at the bottom of the support table 5, and the output part of the motor 14 is fixedly connected to the feeding wheel 12. Exemplarily, when materials enter the hopper 2, through the rotation of the distributing wheel 21, the materials are sent into the distributing box 11 in batches. By driving the feeding wheel 12 to rotate rapidly by the motor 14, centrifugal force can be generated on the materials on the feeding wheel 12. By controlling the rotation speed of the motor 14, the centrifugal force of the materials can be controlled, and the discharging force of the materials can be increased, so as to send the materials to different distances in the calcining furnace and achieve the effect of material distribution.

[0030] It is worth mentioning that the speed control of the motor 14 can be achieved through the PLC, and the control program is set by those skilled in the art according to the actual situation. The amount of materials fed in batches by the distributing wheel 21 is less than or equal to the maximum storage capacity of each compartment on the surface of the feeding wheel 12 to avoid excessive single feeding and causing the feeding wheel 12 to get stuck during rotation. The rotation frequency of the distributing wheel 21 is determined by the art according to the actual situation. The rotation power of the distributing wheel 21 can be provided by a servo motor or a stepping motor, and specific limitations are not made here.

[0031] Further, referring to Figure 1 、 Figure 3 and Figure 4 As shown, in order to further improve the material distribution effect, the distributing box 11 of this embodiment can rotate intermittently left and right to control the discharging direction, so that the materials enter the calcining furnace. It can not only control the material distribution direction deep into the calcining furnace, but also control the material distribution direction on the left and right sides inside the calcining furnace, making the material distribution more dispersed.

[0032] Specifically, referring to Figure 1 、 Figure 3 and Figure 4 As shown, a synchronous mechanism 3 is assembled at the output part of the motor 14. The motor 14 is linked with the distributing box 11 through the synchronous mechanism 3. The synchronous mechanism 3 includes a driving synchronous wheel 31, a driven synchronous wheel 32, a synchronous belt 33, a double-row rack 34, a first transmission member 35 and an arc rack 36. The driving synchronous wheel 31 is coaxially and fixedly connected to the motor 14 and the feeding wheel 12, that is, the driving synchronous wheel 31 is sleeved and fixed on the output end of the motor 14. When the motor 14 drives the feeding wheel 12 to rotate, it can drive the driving synchronous wheel 31 to rotate at the same time. The driven synchronous wheel 32 is rotatably connected to the support table 5, and a half gear 321 is coaxially connected to the bottom of the driven synchronous wheel 32. The two ends of the synchronous belt 33 are respectively sleeved on the driving synchronous wheel 31 and the driven synchronous wheel 32.

[0033] Further, referring toFigure 3 and Figure 4 As shown in Figure 4 , in some embodiments, the driven synchronous pulley 32 and the driving synchronous pulley 31 are not driven by a synchronous belt 33. The driven synchronous pulley 32 and the driving synchronous pulley 31 are directly meshed and driven, and the radius of the driven synchronous pulley 32 is greater than that of the driving synchronous pulley 31. The purpose is to reduce the speed transmitted from the slave motor 14 to the driven synchronous pulley 32 and prevent the fabric box 11 from swinging too fast left and right. In some embodiments, the number of driven synchronous pulleys 32 can also be increased. By controlling the number of driven synchronous pulleys 32 and the transmission gear ratio between multiple driven synchronous pulleys 32, the transmission speed can be further reduced. The specific transmission gear ratio and reduction ratio are determined according to actual needs and are not specifically limited herein;

[0034] Furthermore, referring to Figure 3 and Figure 4 As shown in Figure 4 , the double-row rack 34 is slidably connected to the support platform 5, and the half gear 321 is intermittently meshed with the double-row rack 34. The first transmission member 35 is rotatably connected to the support platform 5. The two ends of the first transmission member 35 are respectively fixed with a first transmission gear 351 and a second transmission gear 352. The first transmission gear 351 is meshed with the double-row rack 34. The arc rack 36 is fixed to the outer surface of the fabric box 11, and the second transmission gear 352 is meshed with the arc rack 36;

[0035] The purpose is that the driven synchronous pulley 32 drives the half gear 321 to rotate. The half gear 321 can drive the double-row rack 34 to reciprocate horizontally, thereby driving the second transmission gear 352 to rotate. The second transmission gear 352 can then drive the arc rack 36 to rotate, thereby driving the fabric box 11 to rotate and changing the discharging direction.

[0036] A discharge port 111 is formed through the outer surface of the fabric box 11. The discharge port 111 is used to discharge the materials in the fabric box 11. A box cover 13 is rotatably connected inside the discharge port 111. The box cover 13 is used to block the discharge port 111. By controlling the opening and closing frequency of the box cover 13, the discharging frequency can be controlled, that is, the feeding frequency into the calciner can be controlled.

[0037] Specifically, two ends of the box cover 13 are fixedly connected with a first connecting shaft 131, and the box cover 13 is rotatably connected to the fabric box 11 through the first connecting shaft 131. An intermittent door opening mechanism 4 is assembled at the end of the first connecting shaft 131, and the box cover 13 is linked with the synchronous mechanism 3 through the intermittent door opening mechanism 4. The intermittent door opening mechanism 4 includes an opening and closing door assembly 41 and a second transmission member 42. The opening and closing door assembly 41 is coaxially connected to the connection point between the box cover 13 and the fabric box 11. The opening and closing door assembly 41 is linked with the synchronous mechanism 3 through the second transmission member 42.

[0038] More specifically, the opening and closing door assembly 41 includes a cam 411, a first connecting rod 412 and a first connecting pile 414. The cam 411 is sleeved on the first connecting shaft 131. One end of the first connecting rod 412 is hinged to the first connecting shaft 131, and the other end is hinged to the push-pull rod 413. The first connecting pile 414 is fixed to the fabric box 11, and the push-pull rod 413 is slidably connected to the first connecting pile 414. Exemplarily, the push-pull rod 413 can slide back and forth in the first connecting pile 414, so that the first connecting rod 412 can be pushed by the push-pull rod 413, so that the first connecting rod 412 drives the first connecting shaft 131 to rotate through the cam 411, thereby driving the box cover 13 to rotate, thereby controlling the opening and closing of the box cover 13.

[0039] For further information, see Figure 4 and Figure 5 As shown, the second transmission member 42 includes a second connecting rod 421, a second connecting pile 423, a third transmission gear 425 and a fixed rack 426. One end of the second connecting rod 421 is hinged to the bottom of the push-pull rod 413, and the other end of the second connecting rod 421 is hinged to the eccentric wheel 422. A second connecting shaft 424 is fixed at the center of the eccentric wheel 422. The second connecting pile 423 is slidably connected to the support platform 5, and the second connecting shaft 424 is rotatably connected to the second connecting pile 423. The third transmission gear 425 is fixed to the end of the second connecting shaft 424. The fixed rack 426 is fixed on the double-row rack 34, and the third transmission gear 425 is meshed with the fixed rack 426; illustratively, the double-row rack 34 can be reciprocated to drive the third transmission gear 425 to rotate through the fixed rack 426, so that the third transmission gear 425 drives the eccentric wheel 422 through the second connecting shaft 424. Since the second connecting rod 421 and the eccentric wheel 422 are eccentrically connected, the rotation of the eccentric wheel 422 can drive the second connecting rod 421 to swing up and down, thereby driving the push-pull rod 413 to move up and down;

[0040] It should be noted that since the opening and closing door assembly 41 is assembled on the fabric box 11, when the fabric box 11 swings left and right, the opening and closing door assembly 41 will also swing along with it. Therefore, the sliding path of the second connecting pile 423 on the support platform 5 is to slide with the center of the fabric box 11 as the axis.

[0041] It is worth mentioning that in some embodiments, the second transmission member 42 can be replaced with an electromagnet or an electric push rod to drive the push-pull rod 413 to reciprocate up and down, and the opening and closing frequency of the box cover 13 is controlled by the starting frequency of the electromagnet and the electric push rod. In some embodiments, the second transmission member 42 can also be replaced with a wedge block, which is fixed on the double-row rack 34. The wedge block is used to directly drive the push-pull rod 413 to reciprocate up and down, which can also achieve the intermittent opening and closing of the box cover 13 as the fabric box 11 swings left and right.

[0042] Further, a guide rod 112 is fixed on the outer surface of the fabric box 11. A connecting cylinder 113 is sleeved on the outer surface of the guide rod 112, and the connecting cylinder 113 is fixed on the support table 5 to ensure the stability of the left - right swing of the fabric box 11.

[0043] In the foregoing, the exemplary embodiments of the solutions proposed in the present disclosure have been described in detail with reference to the preferred embodiments. However, those skilled in the art can understand that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above - mentioned specific embodiments, and various combinations of the technical features and structures proposed in the present disclosure can be made, without exceeding the protection scope of the present disclosure. The protection scope of the present disclosure is determined by the appended claims.
