[0001] The utility model relates to the technical field of static classifiers, in particular to a flow guiding device for a static classifier. Background Art

[0002] Static classifier is a commonly used grading equipment. It controls the fineness of the finished product by adjusting the air volume. The material is dispersed and collided by the baffles inside the classifier to break up the material blocks and fully expose the fine powder, thereby achieving the purpose of classification.

[0003] Although the existing static classifier can classify materials during use, the equipment has a poor diversion effect, which leads to the mixing of materials of different levels during use. At the same time, it is also impossible to collect fine powder, which causes air pollution during discharge, thereby reducing the diversion effect and dust collection effect of the traditional static classifier. For this reason, a diversion device for a static classifier is introduced. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The static classifier uses a flow guide device. When the material is transported from the inner wall of the feed pipe to the inner wall of the limit shell, a signal is sent through the controller, so that the hair dryer blows air after receiving the signal, so that the hair dryer breaks up the transported material, and the fine powder generated by the broken material is blown upward by the air volume of the hair dryer, so that the fine powder is guided by the guide plate and the arc plate to guide the fine powder. The broken material falls from the inner wall of the limit shell and falls into the inner wall of the discharge pipe from the bottom notch of the limit shell for collection. At the same time, the air volume generated by the hair dryer can be transported to the inner wall of the limit shell through the filter plate, and the material is blocked at the same time.

[0013] 2. The guide device for the static classifier receives a signal from the controller through the suction fan, so that the suction fan extracts the fine powder inside the fine powder outlet and conveys it to the inner wall of the conveying pipe, and guides the fine powder through the conveying pipe, so that the fine powder is conveyed from the inner wall of the conveying pipe to the inner wall of the collection box for placement, thereby realizing the collection of the fine powder. When the collection box is replaced, the staff aligns the clamping block with the notch of the clamping slot, so that the clamping block and the clamping slot are clamped, thereby realizing the connection between the collection box and the conveying pipe, and the control is used. The controller sends a signal, which causes the power output shaft of the motor to rotate after receiving the signal, and the motor drives the gear to rotate, and the gear and the rack are meshed for transmission, so that when the gear rotates, it drives the rack and the limit block to move on the inner wall of the fixed block, and the fixed block is used to limit the rack, so that the rack will not fall off or shift when it moves. When the rack moves, it drives the clamping rod to clamp and fix the outer wall of the conveying pipe, so that the conveying pipe will not detach from the outer wall of the collecting box during operation, causing the fine powder in the equipment to be discharged.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 - Figure 6 A flow guide device for a static classifier comprises a static classifier body 1, a feed pipe 2 is fixedly mounted on the outer wall of the static classifier body 1, a fine powder outlet 3 is fixedly mounted on the top of the static classifier body 1, a discharge pipe 8 is fixedly mounted on the bottom of the static classifier body 1, one end of a conveying pipe 4 is fixedly mounted on the outer wall of the fine powder outlet 3, a collecting box 5 is fixedly mounted on the other end of the conveying pipe 4, a controller 6 is fixedly mounted on the outer wall of the collecting box 5, a fixing component 7 is provided on the outer wall of the collecting box 5, a clamping block 16 is fixedly mounted on one side of the collecting box 5 close to the fixing component 7, a clamping groove 15 is provided on one end of the conveying pipe 4 close to the collecting box 5, and a suction fan 13 is fixedly mounted on one end of the conveying pipe 4 away from the collecting box 5.

[0024] In the above structure, when the signal sent by the controller 6 is received by the suction fan 13, the suction fan 13 is responsible for accurately extracting the fine powder inside the fine powder outlet 3 and sending it to the inner wall of the conveying pipe 4. Subsequently, the fine powder is orderly transported to the inner wall of the collecting box 5 under the guidance of the conveying pipe 4 and properly placed, so as to achieve efficient collection of the fine powder. When the collecting box 5 needs to be replaced, the staff will follow the standard operation to ensure that the clamping block 16 is accurately aligned with the notch of the clamping slot 15, and then clamp it, so as to achieve a stable connection between the collecting box 5 and the conveying pipe 4.

[0025] In a preferred embodiment: the inner wall of the static classifier body 1 is fixedly equipped with a limit shell 9, the inner wall of the limit shell 9 is respectively fixedly equipped with a filter plate 10 and a guide plate 11, the top of the guide plate 11 is fixedly equipped with an arc plate 12, and the bottom of the inner wall of the static classifier body 1 is fixedly equipped with a blower 14.

[0026] In the above structure, in the process of the material being transmitted from the inner wall of the feed pipe 2 to the inner wall of the limiting shell 9, the controller 6 triggers a signal to ensure that the hair dryer 14 can receive the signal in time and start the blowing function. Subsequently, the hair dryer 14 performs a breaking operation on the material being transmitted, and uses the air volume generated by it to blow the fine powder generated by the broken material upward. The fine powder is guided by the guide plate 11 and the arc plate 12 to achieve effective fine powder diversion, and the broken material continues to descend from the inner wall of the limiting shell 9, and finally falls into the inner wall of the discharge pipe 8 through the groove at the bottom of the limiting shell 9, completing the collection process. In addition, through the cooperation of the filter plate 10, it is ensured that the air volume generated by the hair dryer 14 can be smoothly transported to the inner wall of the limiting shell 9, and at the same time have a blocking effect on the material.

[0027] In a preferred embodiment: the fixing component 7 includes a motor 701, the power output shaft of the motor 701 is fixedly equipped with a gear 702, the outer wall of the gear 702 is provided with a fixing block 703, the inner wall of the fixing block 703 is slidably connected to a limiting block 704, the top of the limiting block 704 is fixedly equipped with a rack 705, and the outer wall of the rack 705 is fixedly equipped with a clamping rod 706.

[0028] In the above structure, a signal is sent through the controller 6 to ensure that the motor 701 can accurately receive the signal and drive its power output shaft to rotate. Subsequently, the power output shaft of the motor 701 will drive the gear 702 to rotate synchronously. Since there is a meshing transmission relationship between the gear 702 and the rack 705, the rotation of the gear 702 will prompt the rack 705 and the limit block 704 to move along the inner wall in the internal structure of the fixed block 703. The rack 705 is limited by the fixed block 703 to ensure that the rack 705 will not fall off or shift during the movement. At the same time, the movement of the rack 705 will drive the clamping rod 706 to stably clamp and fix the outer wall of the conveying pipe 4 to prevent the conveying pipe 4 from detaching from the outer wall of the collection box 5 during operation.

[0029] In a preferred embodiment, the gear 702 is meshed with the rack 705 for transmission, and the motor 701 and the fixing block 703 are both located on the top of the collecting box 5 and fixedly assembled.

[0030] In the above structure, the gear 702 drives the rack 705 to move during rotation, and the collection box 5 is used to limit the fixing component 7, so that the fixing component 7 will not fall during operation.

[0031] In a preferred embodiment: the conveying pipe 4 is connected to the inner wall of the limiting shell 9 through the fine powder outlet 3, the blower 14, the suction fan 13 and the motor 701 are all electrically connected to the controller 6, and the clamping block 16 is clamped to the inner wall of the clamping groove 15.

[0032] In the above structure, the fine powder outlet 3 and the fine powder inside the limiting shell 9 are transported through the conveying pipe 4, and a signal is sent through the controller 6 to enable the device to work after receiving the signal. The collecting box 5 and the conveying pipe 4 are connected by the clamping block 16 and the inner wall of the clamping groove 15.

[0033] In a preferred embodiment, there are two groups of fixing components 7 , and the two groups of fixing components 7 are respectively located on the top of the collecting box 5 .

[0034] In the above structure, two sets of fixing components 7 are used to clamp and fix the four sides of the delivery tube 4 so that the delivery tube 4 will not fall when placed.

[0035] Working principle: in the process of transferring the material from the inner wall of the feed pipe 2 to the inner wall of the limiting shell 9, the controller 6 sends a signal to trigger the blower 14 to perform the blowing operation to break up the material. The blower 14 adjusts the air volume to blow the fine powder generated by the broken material upward, and the fine powder flows under the guidance of the guide plate 11 and the arc plate 12. The broken material continues to descend along the inner wall of the limiting shell 9, and finally falls into the inner wall of the discharge pipe 8 through the bottom notch of the limiting shell 9, completing the collection process. At the same time, in order to ensure that the air volume can fully cover the inner wall of the limiting shell 9 and properly block the material, the design of the filter plate 10 ensures that the air volume generated by the blower 14 can be smoothly transported to the inner wall of the limiting shell 9. When the suction fan 13 receives the signal sent by the controller 6, it will start the extraction operation of the fine powder inside the fine powder outlet 3, and transport the fine powder to the inner wall of the conveying pipe 4. Under the guidance of the conveying pipe 4, the fine powder is further transported to the inner wall of the collecting box 5 for Storage, thereby realizing the collection of fine powder. When replacing the collection box 5, the staff needs to ensure that the clamping block 16 is accurately aligned with the notch of the clamping groove 15, and connect the clamping block 16 and the clamping groove 15 by clamping, thereby connecting the collection box 5 and the conveying pipe 4. The controller 6 sends a signal again to drive the power output shaft of the motor 701 to rotate. The rotation of the motor 701 will drive the gear 702 to rotate synchronously, and the gear 702 is meshed with the rack 705. The rotation of the gear 702 will drive the rack 705 and the limit block 704 to move orderly on the inner wall of the fixed block 703. The design of the fixed block 703 ensures the stability and accuracy of the rack 705 during the movement, and prevents it from falling off or offset. At the same time, the movement of the rack 705 will drive the clamping rod 706 to clamp and fix the outer wall of the conveying pipe 4, ensuring that the conveying pipe 4 will not detach from the outer wall of the collection box 5 during operation, thereby preventing the leakage of fine powder in the equipment.
