[0002] As an important inorganic compound, bismuth oxide is widely used in many fields such as electronics, ceramics, and glass. In order to enhance the stability of bismuth oxide, make it more stable under different environmental conditions, extend the service life of bismuth oxide, remove impurities and moisture in bismuth oxide, and improve its purity and activity, calcination equipment is often used to calcine bismuth oxide during the processing of bismuth oxide. At the same time, calcining bismuth oxide can change the structure of bismuth oxide crystals and change the physical properties of bismuth oxide, such as hardness, density, color, etc., thereby meeting the needs of different application fields.

[0003] When the existing calcining device for processing bismuth oxide calcines bismuth oxide, since the bismuth oxide raw materials have various sizes, the calcination effects of the bismuth oxide raw materials with different particle sizes are different during calcination. It is easy for the calcination of the bismuth oxide raw materials with smaller particles to be completed, while the calcination of the bismuth oxide raw materials with larger particles is not completed, thereby affecting the calcination effect of the bismuth oxide raw materials. Before calcination, personnel need to manually screen the bismuth oxide raw materials, which affects the calcination efficiency of the bismuth oxide raw materials. At the same time, when the bismuth oxide is directly placed in the calcination furnace for calcination, it is easy for the bismuth oxide raw materials at different positions inside the calcination furnace to be heated unevenly, resulting in a low yield of bismuth oxide after calcination. Therefore, improvement is needed. Summary of the Invention

[0012] A calcining method for a calcining device for processing bismuth oxide, the calcining method comprising the following steps: Insert the L-shaped card into the corresponding rectangular slot, so that the rubber card strip 1 is squeezed and deformed on the inner wall of the rectangular slot, thereby clamping and fixing the L-shaped card into the rectangular slot. Insert the L-shaped card into the corresponding rectangular slot on the surface of the upper barrel in order from large to small according to the size of the mesh of the screen, so that the rubber card strips 2 on both sides of the screen are squeezed and deformed on the inner wall of the rectangular slot, thereby clamping and fixing the screen into the rectangular slot; After the rotating door panel is closed on the surface of the calcining box, the rotating motor is started to control the eccentric wheel to drive the connecting plate to rotate, so that the top of the connecting plate rotates inside the concave seat, and the concave seat is lifted up and moved away from the bottom plate, so that the upper barrel moves up and down on one side of the calcining box, driving the moving bars on both sides of the upper barrel to slide on the surface of the corresponding mounting slide rod, squeezing the vibration spring to deform, so that the upper barrel drives the screen to vibrate up and down synchronously, and pour an appropriate amount of bismuth oxide raw material into the top of the upper barrel. The bismuth oxide raw material falls on the top of the screen and is screened under the vibration of the upper barrel. The screened bismuth oxide raw material is discharged from the lower rack through the arc slot to the inside of the calcining seat; After an appropriate amount of bismuth oxide raw material is placed inside the calcining seat, the motor is stopped so that the loading cylinder stops and does not continue to transport the bismuth oxide raw material. The microwave heating plate is started to control the size of the microwave emitted by the microwave heating plate according to the different particle sizes of the bismuth oxide raw material inside each calcining seat. Since the particles of the bismuth oxide raw material inside the top calcining seat are the largest, the microwaves are emitted from bottom to top and penetrate the three calcining seats in sequence, so that the top calcining seat is subjected to more microwaves, ensuring that the internal molecules of the bismuth oxide raw material with the largest particles vibrate most violently to generate more heat for calcination. At the same time, the stirring motor is started to rotate inside the calcining box through the meshing control of the bevel gear 2 and the bevel gear 1, driving the arc-shaped stirring frame to rotate inside the corresponding calcining seat. The inner arc surface of the arc-shaped stirring frame pushes the bismuth oxide raw material inside the calcining seat to move, ensuring that the bismuth oxide raw material inside the calcining seat is evenly subjected to the microwaves emitted by the microwave heating plate for calcination; After the calcination is completed and the bismuth oxide raw material is naturally cooled to room temperature, the door panel is turned to open, the arc-shaped baffle is pulled out from the inside of the discharge chute, the collecting seat is taken and suspended at the opening of the discharge chute, the stirring motor is controlled to reverse, and the linkage shaft is controlled to drive the arc-shaped stirring frame to reverse inside the calcination seat, so that the outer arc surface of the arc-shaped stirring frame pushes the bismuth oxide raw material inside the calcination seat, and pushes the bismuth oxide raw material toward the inner wall of the calcination seat away from the connecting cylinder until the bismuth oxide raw material is discharged from the discharge chute.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a rotating motor, an eccentric wheel, a connecting plate, a loading barrel, a vibration spring and a screen are set, and the screen is inserted into the corresponding rectangular through-slot in sequence according to the size of the screen holes. The rotating motor is started to control the eccentric wheel to rotate, so that the connecting plate moves on the surface of the eccentric wheel to push the loading barrel to vibrate up and down. During the up and down vibration process, the loading barrel drives the moving bar to slide on the surface of the corresponding mounting slide rod, squeezing the vibration spring to deform, causing the vibration spring to squeeze and rebound, assisting the loading barrel to vibrate up and down, and then pouring an appropriate amount of bismuth oxide raw material into the top of the upper barrel. As the loading barrel vibrates up and down, the bismuth oxide raw material is vibrated and sieved on the top of the screen. The bismuth oxide raw material after screening is input from the unloading rack into the calcination seat inside the calcination box, so that the bismuth oxide raw material can be layered and calcined according to the particle size of the bismuth oxide raw material, thereby improving the calcination efficiency of the bismuth oxide raw material.

[0014] 2. In the present invention, a calcining seat, an arc-shaped baffle, a microwave heating plate, a linkage shaft, an arc-shaped stirring frame and a stirring motor are provided. After the bismuth oxide raw material is poured into the calcining seat, the stirring motor is started to control the linkage shaft to rotate, driving the arc-shaped stirring frame to rotate inside the corresponding calcining seat, so that the inner arc surface of the arc-shaped stirring frame pushes the bismuth oxide raw material to move inside the calcining seat, so that the bismuth oxide raw material inside the calcining seat is evenly heated and calcined. At the same time, the microwave heating plate is started to emit microwaves to heat and calcine the bismuth oxide raw material inside the calcining seat. Since the bismuth oxide raw material particles in the top calcining seat are larger, microwaves are emitted from bottom to top, so that the bottom calcining seat is subjected to more microwaves, so that the heating and calcining effect of the top calcining seat is better. After the calcination is completed and the bismuth oxide raw material is cooled, the arc-shaped baffle is pulled out of the discharge chute, and the stirring motor is controlled to reverse so that the outer arc surface of the arc-shaped stirring frame pushes the bismuth oxide raw material inside the calcining seat to move until the bismuth oxide raw material is pushed to the discharge chute for discharge, thereby facilitating the removal of the calcined bismuth oxide raw material.

DETAILED DESCRIPTION

[0016] The technical solution of the present application will be further described in detail below in conjunction with specific implementation methods.

[0017] like Figure 1-2 As shown, the present invention provides a technical solution: a calcining device for processing bismuth oxide, comprising a calcining box 1. A door panel 101 is symmetrically mounted on one side of the calcining box 1 via a pin. Closing the door panel 101 reduces heat loss during calcination within the calcining box 1, while simultaneously increasing the temperature and pressure within the calcining box 1 during heating. Three arcuate slots 102 are equidistantly formed on the surface of the calcining box 1 away from the door panel 101. The arcuate slots 102 communicate with the interior of the calcining box 1, allowing air to circulate inside and outside the calcining box 1, thereby preventing the calcining box 1 from bursting due to excessive internal pressure.

[0018] like Figure 3 The inner wall of the calcining box 1 shown is located at the bottom of each arc-shaped through groove 102, and a calcining seat 2 is fixedly installed. A connecting tube 201 is fixedly installed at the central position inside the calcining seat 2, and the upper and lower ends of the connecting tube 201 are connected; a side wall of the surface of the calcining seat 2 is provided with a discharge groove 202, and an elastic protrusion 203 is fixedly installed at the bottom of the inner side of the discharge groove 202. Limiting strips 204 are symmetrically fixedly installed on the inner walls on both sides of the discharge groove 202, and an arc-shaped baffle 205 is slidably installed inside the discharge groove 202. Limiting slots 206 are symmetrically provided on both sides of the arc-shaped baffle 205. The limiting slots 206 pass through and are slidably connected to the surface of the arc-shaped baffle 205, and the limiting slots 206 cooperate with the limiting strips 204 to limit the position. A microwave heating plate 207 is provided at the bottom of the calcining seat 2.

[0019] After the bismuth oxide raw material is poured into the calcining seat 2, the microwave heating plate 207 is started to emit microwaves into the calcining seat 2. When the microwaves pass through the bismuth oxide raw material, the molecular vibration inside the bismuth oxide raw material generates heat, which heats and calcines the bismuth oxide raw material. When the calcined bismuth oxide raw material is discharged, the arc baffle 205 is pulled out from the discharge trough 202 to discharge the bismuth oxide raw material from the discharge trough 202; at the same time, during calcination, the arc baffle 205 is inserted into the discharge trough 202, so that the limiting grooves 206 on both sides of the arc baffle 205 are stuck on the surface of the corresponding limiting strip 204 until the inner wall of the arc baffle 205 squeezes the elastic protrusion 203 to deform, thereby clamping the arc baffle 205 inside the discharge trough 202, ensuring that the bismuth oxide raw material will not be discharged from the discharge trough 202 when calcining inside the calcining seat 2.

[0020] A stirring mechanism 3 is rotatably installed inside the calcining box 1 through a bearing, and a stirring motor 7 is fixedly installed on one side of the top of the calcining box 1. The stirring mechanism 3 includes a linkage shaft 301, and the linkage shaft 301 is rotatably connected to the inside of the connecting cylinder 201 through a bearing. Both ends of the linkage shaft 301 are rotatably connected to the inside of the calcining box 1 through bearings. A bevel gear 1 302 is fixedly installed on the top of the linkage shaft 301 passing through the calcining box 1. A plurality of arc-shaped stirring frames 303 are fixedly installed on the surface of the linkage shaft 301 located inside the calcining box 1, and the arc-shaped stirring frames 303 are tightly attached to the inner wall of the calcining seat 2; a bevel gear 2 701 is fixedly installed on the output end of the stirring motor 7, and the bevel gear 2 701 is meshed with the bevel gear 1 302.

[0021] Start the stirring motor 7 and control the linkage shaft 301 to rotate under the engagement of bevel gear 2 701 and bevel gear 1 302, so that the arc-shaped stirring frame 303 rotates forward inside the calcining seat 2. The inner arc surface of the arc-shaped stirring frame 303 pushes the bismuth oxide raw material in the calcining seat 2 to move, so that the bismuth oxide raw material inside the calcining seat 2 is heated evenly during heating and calcining. When the stirring motor 7 controls the linkage shaft 301 to drive the arc-shaped stirring frame 303 to reverse, the outer arc surface of the arc-shaped stirring frame 303 pushes the bismuth oxide raw material inside the calcining seat 2 to move away from the connecting tube 201 until the arc-shaped stirring frame 303 pushes the bismuth oxide raw material to be discharged from the discharge trough 202, making it convenient to take out the heated and calcined bismuth oxide raw material.

[0022] like Figure 4 As shown, a reciprocating vibration mechanism 4 is fixedly installed on the bottom of the surface of the calcining box 1 away from the door panel 101. The reciprocating vibration mechanism 4 includes a bottom plate 401, a rotating motor 402 is fixedly installed on one side of the top of the bottom plate 401, and a support plate 403 is symmetrically fixedly installed on one side of the top of the bottom plate 401 located at the output end of the rotating motor 402. Eccentric wheels 404 are rotatably installed on opposite sides of the two support plates 403 through bearings, and a connecting plate 405 is rotatably installed between the two eccentric wheels 404 through a pin shaft. A concave seat 406 is rotatably installed on the top of the connecting plate 405 through a pin shaft, and one side of one eccentric wheel 404 passes through the support plate 403 and is fixedly connected to the output end of the rotating motor 402.

[0023] Start the rotating motor 402 to control the eccentric wheel 404 to rotate, so that the connecting plate 405 rotates between the two eccentric wheels 404. At the same time, the top of the connecting plate 405 rotates inside the concave seat 406. The top of the concave seat 406 is fixedly connected to the bottom of the screening and feeding mechanism 5, which lifts up the concave seat 406 to move up and down, controlling the screening and feeding mechanism 5 to vibrate up and down.

[0024] like Figure 5-6As shown, the surface of the calcining box 1 located on the top of the reciprocating vibration mechanism 4 is provided with a screening and feeding mechanism 5, and the screening and feeding mechanism 5 includes a feeding barrel 501, the bottom of the feeding barrel 501 is fixedly connected to the concave seat 406, and three rectangular through grooves 502 are equidistantly provided on the surface of the feeding barrel 501, and the rectangular through grooves 502 pass through both sides of the feeding barrel 501; a discharge rack 503 is fixedly installed at the opening on one side of the rectangular through groove 502 on the surface of the feeding barrel 501, and the discharge rack 503 corresponds to the position of the arc-shaped through groove 102.

[0025] Three screens 6 are slidably mounted within the rectangular through-slot 502, and the mesh sizes of the three screens 6 decrease from top to bottom. The three screens 6 are slightly tilted toward the unloading rack 503, and there is a gap between one side of the screen 6 and the rectangular through-slot 502, making it easier for the material to fall along the screen into the unloading rack 503 after being screened. The material falls onto the slightly tilted screen 6, causing the material to vibrate as the loading barrel 501 drives the screen 6 to flow toward the unloading rack 503 and be discharged from the loading barrel 501. A rectangular slot 601 is provided on the other side of the screen 6, and an L-shaped card plate 602 is inserted into the interior of the rectangular slot 601. Rubber clip strips 603 are fixedly mounted on both sides of the L-shaped card plate 602, and the rubber clip strips 603 are tightly attached to the inner wall of the rectangular slot 601; rubber clip strips 604 are fixedly mounted on both sides of the screen 6, and the rubber clip strips 604 are tightly attached to the inner wall of the rectangular through-slot 502.

[0026] By installing the screen 6, an L-shaped clamping plate 602 is inserted into the rectangular slot 601, causing the first rubber clamping strip 603 to be squeezed and deformed against the inner wall of the rectangular slot 601, thereby clamping and fixing the L-shaped clamping plate 602 in the rectangular slot 601. The screen 6 is then inserted into the rectangular through-slot 502 in order of mesh size, causing the second rubber clamping strip 604 to be squeezed and deformed against the inner wall of the rectangular through-slot 502, until the bottom of the L-shaped clamping plate 602 abuts against the outer wall of the upper barrel 501, thereby clamping and fixing the screen 6 in the rectangular through-slot 502. The bismuth oxide raw material poured from the top of the upper barrel 501 is screened by the screen 6, and the larger bismuth oxide raw material is fed from the top unloading rack 503 into the calcination seat 2 inside the calcination box 1 for calcination, thereby facilitating the calcination of the bismuth oxide raw material in layers according to the size of the raw material.

[0027] Moving bars 504 are symmetrically fixedly installed on both sides of the loading barrel 501, and mounting slide rods 505 are symmetrically slidably installed at both ends of the moving bars 504. The top and bottom ends of the two mounting slide rods 505 are fixedly installed with fixed bars 506, and one end of the fixed bar 506 is fixedly connected to the surface of the calcining box 1. The surface of the mounting slide rod 505 located between the top of the moving bar 504 and the fixed bar 506 is sleeved with a vibration spring 507; a discharge port 508 is provided at the bottom of the loading barrel 501 away from the calcining box 1.

[0028] When the loading barrel 501 vibrates up and down as the concave seat 406 is lifted, it drives the moving bar 504 to slide on the surface of the corresponding mounting slide rod 505, causing the vibration spring 507 to be squeezed and rebounded on the surface of the mounting slide rod 505. When the vibration spring 507 is squeezed and rebounded, it assists the loading barrel 501 to vibrate, thereby improving the vibration effect of the loading barrel 501 on the bismuth oxide raw material.

[0029] A calcining method for a calcining device for processing bismuth oxide, the calcining method comprising the following steps: Insert the L-shaped card plate 602 into the corresponding rectangular slot 601, so that the rubber card strip 1 603 is squeezed and deformed on the inner wall of the rectangular slot 601, thereby clamping and fixing the L-shaped card plate 602 inside the rectangular slot 601, and insert the screen 6 into the corresponding rectangular slot 502 on the surface of the loading barrel 501 in order from large to small according to the size of the screen holes, so that the rubber card strips 2 604 on both sides of the screen 6 are squeezed and deformed on the inner wall of the rectangular slot 502, thereby clamping and fixing the screen 6 inside the rectangular slot 502; After the rotating door panel 101 is closed on the surface of the calcining box 1, the rotating motor 402 is started to control the eccentric wheel 404 to drive the connecting plate 405 to rotate, so that the top of the connecting plate 405 rotates inside the concave seat 406, and the concave seat 406 is lifted up and moved away from the bottom plate 401, so that the upper barrel 501 moves up and down on one side of the calcining box 1, driving the moving bars 504 on both sides of the upper barrel 501 to slide on the surface of the corresponding mounting slide rod 505, squeezing the vibration spring 507 to deform, so that the upper barrel 501 drives the screen 6 to vibrate up and down synchronously, and pour an appropriate amount of bismuth oxide raw material into the top of the upper barrel 501. The bismuth oxide raw material falls on the top of the screen 6 and is screened under the vibration of the upper barrel 501. The screened bismuth oxide raw material is discharged from the lower rack 503 through the arc-shaped through slot 102 to the inside of the calcining seat 2; After an appropriate amount of bismuth oxide raw material is placed inside the calcining seat 2, the rotating motor 402 is stopped so that the loading cylinder 501 stops and does not continue to transport the bismuth oxide raw material, and the microwave heating plate 207 is started to control the size of the microwave emitted by the microwave heating plate 207 according to the different particle sizes of the bismuth oxide raw material inside each calcining seat 2. Since the particles of the bismuth oxide raw material inside the top calcining seat 2 are the largest, and the microwaves are emitted from bottom to top and penetrate the three calcining seats 2 in sequence, the top calcining seat 2 is subjected to more microwaves, ensuring that the internal molecular vibration of the bismuth oxide raw material with the largest particles is the most intense, generating more heat for calcination. At the same time, the stirring motor 7 is started to rotate inside the calcining box 1 through the meshing control of the bevel gear 2 701 and the bevel gear 1 302, driving the arc-shaped stirring frame 303 to rotate inside the corresponding calcining seat 2. The inner arc surface of the arc-shaped stirring frame 303 pushes the bismuth oxide raw material inside the calcining seat 2 to move, ensuring that the bismuth oxide raw material inside the calcining seat 2 is evenly subjected to the microwaves emitted by the microwave heating plate 207 for calcination; After the calcination is completed and the bismuth oxide raw material is naturally cooled to room temperature, the door panel 101 is rotated to open, the arc-shaped baffle 205 is pulled out from the discharge chute 202, and the collecting seat is suspended at the opening of the discharge chute 202. The stirring motor 7 is controlled to reverse, and the linkage shaft 301 is controlled to drive the arc-shaped stirring frame 303 to reverse inside the calcination seat 2, so that the outer arc surface of the arc-shaped stirring frame 303 pushes the bismuth oxide raw material inside the calcination seat 2, pushing the bismuth oxide raw material toward the inner wall of the calcination seat 2 away from the connecting tube 201 until the bismuth oxide raw material is discharged from the discharge chute 202.

A calcination method for a calcination device for processing bismuth oxide, according to any one of claims 1 to 7, characterized in that: The calcination method comprises the following steps: Insert the L-shaped card plate (602) into the corresponding rectangular slot (601), so that the rubber card strip (603) is squeezed and deformed on the inner wall of the rectangular slot (601), thereby clamping and fixing the L-shaped card plate (602) inside the rectangular slot (601), and insert the L-shaped card plate (602) into the corresponding rectangular slot (502) on the surface of the loading barrel (501) in order from large to small according to the size of the sieve holes of the sieve (6), so that the rubber card strips (604) on both sides of the sieve (6) are squeezed and deformed on the inner wall of the rectangular slot (502), thereby clamping and fixing the sieve (6) inside the rectangular slot (502); After the rotating door panel (101) is closed on the surface of the calcining box (1), the rotating motor (402) is started to control the eccentric wheel (404) to drive the connecting plate (405) to rotate, so that the top of the connecting plate (405) rotates inside the concave seat (406), and the concave seat (406) is lifted up and moved away from the bottom plate (401), so that the upper barrel (501) moves up and down on one side of the calcining box (1), driving the moving bars (504) on both sides of the upper barrel (501) to slide on the surface of the corresponding mounting slide rod (505), squeezing the vibration spring (507) to deform, so that the upper barrel (501) drives the screen (6) to vibrate up and down synchronously, and pours an appropriate amount of bismuth oxide raw material into the top of the upper barrel (501). The bismuth oxide raw material falls on the top of the screen (6) and is screened under the vibration of the upper barrel (501). The screened bismuth oxide raw material is discharged from the lower rack (503) through the arc-shaped through groove (102) to the inside of the calcining seat (2); After placing an appropriate amount of bismuth oxide raw material inside the calcining seat (2), the motor (402) is stopped so that the feeding cylinder (501) stops and does not continue to transport the bismuth oxide raw material. The microwave heating plate (207) is started to control the size of the microwave emitted by the microwave heating plate (207) according to the different particle sizes of the bismuth oxide raw material inside each calcining seat (2). Since the particles of the bismuth oxide raw material inside the top calcining seat (2) are the largest, the microwaves are emitted from the bottom to the top and penetrate the three calcining seats (2) in sequence, so that the top calcining seat (2) is subjected to more microwaves, ensuring that the particles with the largest oxide are heated. The molecular vibration inside the bismuth oxide raw material is the most intense, generating more heat for calcination. At the same time, the stirring motor (7) is started to rotate the linkage shaft (301) inside the calcination box (1) through the meshing control of the bevel gear 2 (701) and the bevel gear 1 (302), driving the arc-shaped stirring rack (303) to rotate inside the corresponding calcination seat (2). The inner arc surface of the arc-shaped stirring rack (303) pushes the bismuth oxide raw material inside the calcination seat (2) to move, ensuring that the bismuth oxide raw material inside the calcination seat (2) is evenly subjected to the microwaves emitted by the microwave heating plate (207) for calcination. After the bismuth oxide raw material is naturally cooled to room temperature after calcination, the door panel (101) is rotated to open, the arc-shaped baffle (205) is pulled out from the inside of the discharge trough (202), the collecting seat is taken and suspended at the opening of the discharge trough (202), the stirring motor (7) is controlled to reverse, and the linkage shaft (301) is controlled to drive the arc-shaped stirring frame (303) to reverse inside the calcination seat (2), so that the outer arc surface of the arc-shaped stirring frame (303) pushes the bismuth oxide raw material inside the calcination seat (2), and pushes the bismuth oxide raw material toward the inner wall of the calcination seat (2) away from the connecting tube (201), until the bismuth oxide raw material is discharged from the discharge trough (202).
