DETAILED DESCRIPTION

[0024] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure. Example

[0025] See also Figure 1 and Figure 2 As shown, the feeding and distribution structure of the efficient calcining furnace for synthesizing zeolite from steel blast furnace slag 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. The inside of the feeding hopper 2 is rotatably connected to a dividing wheel 21. The outer surface of the dividing wheel 21 is evenly provided with compartments for storing materials. By rotating the dividing wheel 21, the dividing wheel 21 receives the materials and reverses them to discharge them from the bottom. A sealing cover 22 is fixed to the bottom of the feeding hopper 2. The outer surface of the sealing cover 22 is provided with through holes for allowing materials to pass through.

[0026] For further information, see Figure 1 and Figure 2 As shown, a feeding mechanism 1 is installed at the bottom of the feeding hopper 2, and 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 platform 5 and the cover 22 respectively. The distributing box 11 is used to realize distributing materials by rotating to control the feeding angle. The feeding wheel 12 is rotatably connected to the distributing box 11. The feeding wheel 12 is used to increase the feeding force by centrifugal force. The motor 14 is fixed to the bottom of the support platform 5, and the output part of the motor 14 is fixedly connected to the feeding wheel 12. Exemplarily, the material enters the feeding hopper 2, and the material is fed into the distributing box 11 in batches through the rotation of the dividing wheel 21. The feeding wheel 12 is driven to rotate rapidly by the motor 14, so that the material on the feeding wheel 12 can generate centrifugal force. By controlling the rotation speed of the motor 14, the centrifugal force of the material can be controlled, and the force of material discharge can be increased, so that the material is fed to different distances in the calcining furnace to achieve the effect of distributing materials. It is worth mentioning that the speed control of the motor 14 can be achieved through PLC, and the control program is set by technical personnel in this field according to actual conditions. The amount of material fed by the dividing wheel 21 in batches is less than or equal to the maximum storage capacity of each compartment on the surface of the feeding wheel 12, so as to avoid excessive feeding at a single time, which may cause the feeding wheel 12 to get stuck when rotating. The rotation frequency of the dividing wheel 21 is determined by the field according to actual conditions. The rotation power of the dividing wheel 21 can be provided by a servo motor or a stepper motor, which is not specifically limited here.

[0027] For further information, see Figure 1 , Figure 3 and Figure 4 As shown, in order to further improve the material distribution effect, the material distribution box 11 of this embodiment can intermittently rotate left and right to control the direction of material discharge, so that the material can 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 of the calcining furnace, so that the material distribution is more dispersed.

[0028] For details, see Figure 1 , Figure 3 and Figure 4 As shown, the output part of the motor 14 is equipped with a synchronous mechanism 3, and the motor 14 is linked with the fabric box 11 through the synchronous mechanism 3. The synchronous mechanism 3 includes an active 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-shaped rack 36. The active synchronous wheel 31 is coaxially fixedly connected with the motor 14 and the feed wheel 12, that is, the active synchronous wheel 31 is sleeved and fixed on the output end of the motor 14. The motor 14 drives the feed wheel 12 to rotate and can drive the active synchronous wheel 31 to rotate. The driven synchronous wheel 32 is rotatably connected with the support table 5. The bottom of the driven synchronous wheel 32 is coaxially connected with a half gear 321, and the two ends of the synchronous belt 33 are respectively sleeved on the active synchronous wheel 31 and the driven synchronous wheel 32; For further information, see Figure 3 and Figure 4 As shown, in some embodiments, the driven synchronous wheel 32 and the active synchronous wheel 31 are not driven by the synchronous belt 33, and the driven synchronous wheel 32 and the active synchronous wheel 31 are directly meshed and driven, and the radius of the driven synchronous wheel 32 is greater than the radius of the active synchronous wheel 31, the purpose is to reduce the speed of the transmission from the motor 14 to the driven synchronous wheel 32, to prevent the material box 11 from swinging too fast left and right. In some embodiments, the number of driven synchronous wheels 32 can be increased, and the transmission speed can be further reduced by controlling the number of driven synchronous wheels 32 and the transmission gear ratio between multiple driven synchronous wheels 32. The specific transmission gear ratio and reduction ratio are determined according to actual needs and are not specifically limited here. For further information, see Figure 3 and Figure 4 As shown, 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, and the first transmission gear 351 and the second transmission gear 352 are respectively fixed at both ends of the first transmission member 35, the first transmission gear 351 is meshed with the double-row rack 34, the arc-shaped rack 36 is fixed to the outer surface of the fabric box 11, and the second transmission gear 352 is meshed with the arc-shaped rack 36; The purpose is to drive the half gear 321 to rotate through the driven synchronous wheel 32, and the half gear 321 can drive the double-row rack 34 to reciprocate, thereby driving the second transmission gear 352 to rotate, and the second transmission gear 352 can drive the arc rack 36 to rotate, thereby driving the material box 11 to rotate and change the direction of material discharge.

[0029] A discharge port 111 is formed on the outer surface of the material distribution box 11, and the discharge port 111 is used to discharge the material in the material distribution box 11. A box cover 13 is rotatably connected to the discharge port 111, and 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 discharge frequency can be controlled, that is, the feeding frequency into the calcining furnace can be controlled.

[0030] Specifically, the first connecting shaft 131 is fixed at both ends of the box cover 13, and the box cover 13 is rotatably connected to the fabric box 11 through the first connecting shaft 131, and the end of the first connecting shaft 131 is equipped with an intermittent door opening mechanism 4, and the box cover 13 is linked with the synchronization mechanism 3 through the intermittent door opening mechanism 4, and 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, and the second transmission member 42 The opening and closing door assembly 41 is linked with the synchronization mechanism 3 through the second transmission member 42.

[0031] 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.

[0032] For further information, see Figure 4 and Figure 5As 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; 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.

[0033] 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.

[0034] Furthermore, a guide rod 112 is fixed to the outer surface of the fabric box 11, and a connecting tube 113 is sleeved on the outer surface of the guide rod 112, and the connecting tube 113 is fixed on the support platform 5 to ensure the stability of the fabric box 11 when swinging left and right.

[0035] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art 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 technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
