[0031] The utility model is further described in conjunction with the following embodiments.

[0032] Example 1.

[0033] like Figure 1-3 As shown, a high-purity magnesia sand heating shaft furnace with uniform discharge comprises a positioning base 1, on which two positioning brackets 2 are fixedly mounted, a heating shaft furnace 3 is fixedly mounted on the top of the two positioning brackets 2, a collecting box 4 is also fixedly mounted on the positioning base 1, a dispersing discharge mechanism 5 is connected and mounted between the collecting box 4 and the heating shaft furnace 3, the dispersing discharge mechanism 5 is fixedly connected to the positioning bracket 2 via a positioning arm 6, a driving assembly 7 is also fixedly mounted on the positioning bracket 2, and the driving assembly 7 and the dispersing discharge mechanism 5 are matched in transmission.

[0034] The present application is used to evenly distribute the discharge of a high-purity magnesia heating shaft furnace. First, the overall equipment is supported by a positioning base 1, and the tops of two positioning brackets 2 are used to fix the heating shaft furnace 3. After the heating shaft furnace 3 heats the high-purity magnesia, the discharge from the bottom enters the dispersing discharge mechanism 5 for even distribution, and then flows into the interior of the collecting box 4. The dispersing discharge mechanism 5 is driven by a driving component 7 to rotate and crush the high-purity magnesia to prevent large particles of high-purity magnesia from blocking the discharge port and causing uneven discharge.

[0035] The dispersed discharge mechanism 5 includes an upper outer cover body 51 and a lower outer cover body 52. ​​A docking feed pipe 53 is provided on the top of the upper outer cover body 51. The docking feed pipe 53 is sleeved on the outside of the discharge pipe of the heating shaft furnace 3. A docking discharge pipe 54 is provided on the bottom of the lower outer cover body 52. ​​A collecting feed pipe 8 is provided on the top of the collecting box body 4. The docking discharge pipe 54 is inserted into the inside of the collecting feed pipe 8. A distributing assembly 55 is rotatably installed between the upper outer cover body 51 and the lower outer cover body 52. ​​The distributing assembly 55 and the driving assembly 7 are matched in transmission.

[0036] The dispersing discharging mechanism 5 is connected to the heating shaft furnace 3 through the connecting feed pipe 53 on the upper outer cover 51, and the connecting discharge pipe 54 on the lower outer cover 52 cooperates with the collecting feed pipe 8 to realize the connection between the lower outer cover 52 and the collecting box 4. The material distribution component 55 rotates between the upper outer cover 51 and the lower outer cover 52, and at the same time, the high-purity magnesia sand is rotated and crushed to avoid blockage caused by large particles of high-purity magnesia sand. The outflow range of the high-purity magnesia sand is expanded by the material distribution component 55, and then it is collected on the lower outer cover 52 to achieve uniform discharging. The material distribution component 55 is driven to rotate between the upper outer cover 51 and the lower outer cover 52 by the driving component 7. The upper outer cover 51 and the lower outer cover 52 are both fixedly mounted on the positioning bracket 2 through the positioning arm 6.

[0037] The material distribution component 55 includes a rotating disk 551, on which a plurality of balls 552 are rotatably installed. Rolling grooves 553 are provided on the upper outer cover body 51 and the lower outer cover body 52, and the balls 552 and the rolling grooves 553 are rollingly matched. A material distribution cone 554 is fixedly connected and installed inside the rotating disk 551, and a plurality of protruding blocks A 555 are provided on the material distribution cone 554. A plurality of protruding blocks B 556 are fixedly installed on the inner wall of the upper outer cover body 51, and the protruding blocks A 555 and the protruding blocks B556 are staggered and matched. A plurality of gears A 557 are installed on the outer wall of the rotating disk 551, and the gears A 557 are meshed with the driving component 7.

[0038] The material distribution component 55 is rotated by meshing the gear A 557 and the driving component 7. The gear A 557 drives the rotating disk 551 to rotate between the upper outer cover 51 and the lower outer cover 52 through the cooperation of the ball 552 and the rolling groove 553. At the same time, the rotating disk 551 drives the material distribution cone 554 to rotate. The protruding blocks A 555 and the protruding blocks B 556 on the material distribution cone 554 are staggered to rotate and crush the large particles of high-purity magnesia to prevent the high-purity magnesia from being blocked.

[0039] The driving assembly 7 includes a positioning support plate 71, on which a matching driving motor 72 and a reducer 73 are fixedly mounted. A gear B 74 is fixedly mounted on the output end of the reducer 73, and the gear B 74 is meshed with the gear A 557.

[0040] The driving assembly 7 fixes the driving motor 72 and the reducer 73 through the positioning support plate 71. The driving motor 72 drives the output of the reducer 73, thereby driving the gear B 74 to rotate, and the gear A 557 is driven to rotate through the engagement of the gear B 74 and the gear A 557.

[0041] The inclination angle of the side wall of the material distribution cone 554 is the same as the inclination angle of the inner wall of the upper outer cover body 51.

[0042] It is convenient for uniformly crushing large particles of high-purity magnesia.

[0043] The rotating disk 551 and the distributing cone 554 are fixedly connected via a connecting rod 9 .

[0044] The installation of the connecting rod 9 reduces the obstruction to the discharge of high-purity magnesia.

[0045] The utility model transitionally connects the heating shaft furnace 3 and the collecting box 4 through the dispersing discharging mechanism 5, and utilizes the driving mechanism to drive the distributing component 55 to rotate and cooperate with the upper outer cover 51, so as to crush the large particles of high-purity magnesia sand, and disperse and slide them into the inside of the collecting box 4, so as to realize the uniform discharging of the high-purity magnesia sand.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
