Description

Technical Field

[0001] The present invention relates to the technical field of fluorite block transportation, and in particular to an automatic transportation device and method for processing calcined fluorite blocks. Background Art

[0002] Fluorite blocks refer to lump-shaped raw ore mainly composed of calcium fluoride. They are usually colorless, green, blue, purple, yellow, etc. They are widely used in chemical, metallurgical, ceramic, glass and other industries. During the calcination process, fluorite blocks are usually fed and discharged efficiently using a conveying device to improve the calcination efficiency of the fluorite blocks. Existing conveying devices use various methods to convey fluorite blocks, such as a powder-removing stone conveying device with publication number CN108861460B, which includes a conveyor belt mechanism, a frame, a hinge shaft, a lifting connecting rod, and a tilting oil cylinder. It also includes a receiving bucket for receiving materials to the feed end of the conveyor belt mechanism, a powder collecting hopper for collecting stone powder, one end of which is longitudinally rotatably mounted on the frame and has an opening at the upper end and the side discharge point, and a support platform fixed to the ground for supporting the free end of the powder collecting hopper; the upper end opening of the powder collecting hopper is exactly in contact with the bottom of the receiving hopper when receiving materials; The existing conveying device only uses a conveyor belt to convey the fluorite blocks to the calcining furnace for overall calcination, but does not stratify the fluorite blocks according to their volumes during transportation, causing fluorite blocks of different volumes to pile up together, making it impossible to carry out targeted calcination. For example, the above-mentioned prior art reference uses a conveyor belt mechanism to convey the material as a whole, but does not automatically grade the material according to its volume. At the same time, after the material is calcined, the calcined waste and the fluorite block residue are not screened and removed. The fluorite block residue and the calcined waste are mixed together and transported together, making it impossible to achieve automatic screening and transportation of the calcined waste and the fluorite block residue, and thus unable to achieve targeted transportation, resulting in poor transportation effect. Therefore, it is urgent to design an automated conveying device and method for calcined fluorite block processing to solve the above problems. Summary of the Invention

[0027] An inclined material distribution conveyor belt 4 is arranged below the feeding conveyor belt 3, and a plurality of grading holes for grading fluorite blocks are arranged on the feeding conveyor belt 3; When the feeding conveyor belt 3 conveys the fluorite block raw materials, due to the different sizes of the fluorite block raw materials, the smaller fluorite block raw materials will fall through the multiple grading holes on the feeding conveyor belt 3 and land on the material distributing conveyor belt 4, thus realizing the automatic screening of the fluorite block raw materials during the conveying process according to the volume size; After the smaller fluorite block raw materials land on the material distributing conveyor belt 4, they will continue to be conveyed along with the material distributing conveyor belt 4 and finally be conveyed into the interior of the calcination furnace 2 for calcination.

[0028] In a further embodiment, a main calcination area and a secondary calcination area are provided in the calcination cylinder 11, and the feeding conveyor belt 3 is connected to the main calcination area in the calcination cylinder 11, and the material distributing conveyor belt 4 is connected to the secondary calcination area in the calcination cylinder 11, and the main calcination area and the secondary calcination area are used for targeted calcination processing of fluorite blocks of different sizes; The large-sized fluorite blocks on the feeding conveyor belt 3 will fall into the interior of the main calcination area in the calcination cylinder 11, and the small-sized fluorite blocks on the material distributing conveyor belt 4 will fall into the secondary calcination area in the calcination cylinder 11. At this time, starting the calcination cylinder 11 can respectively carry out targeted high-temperature calcination on the fluorite block raw materials in the main calcination area and the secondary calcination area.

[0029] An air conveying component for collecting calcination gas is provided on the calcination furnace 2. The air conveying component includes an exhaust pipe 12 and an exhaust pipe 13 fixedly connected between the calcination cylinder 11 and the calcination furnace 2. The exhaust pipe 12 is used for collecting the gas generated in the main calcination area, and the exhaust pipe 13 is used for collecting the gas generated in the secondary calcination area. A main air guiding pipe 7 is commonly connected to the exhaust pipe 12 and the exhaust pipe 13; During the calcination of the fluorite block raw materials in the main calcination area and the secondary calcination area in the calcination cylinder 11, a certain amount of hydrogen fluoride gas will be generated. The gas generated in the main calcination area will enter the exhaust pipe 12, and the gas generated in the secondary calcination area will enter the exhaust pipe 13, so that the gas generated during calcination can be automatically collected and conveyed; A filter cylinder 10 for filtering gas impurities is fixedly connected to the main air guiding pipe 7. The hydrogen fluoride gas in the exhaust pipe 12 and the exhaust pipe 13 will enter the main air guiding pipe 7 and continue to be conveyed after passing through the filter cylinder 10. At this time, the filter cylinder 10 will filter and remove the hydrogen fluoride gas, filter out the dust impurities attached to the hydrogen fluoride gas, and then convey out relatively pure hydrogen fluoride gas.

[0030] Embodiment Three: Refer to 1- Figure 2 and Figures 6-15 , the different technical solution of this embodiment compared with Embodiment Two is that the conveying unit includes a collecting component, a crushing component and an output conveying component, and a screening cylinder 18 for collecting calcined materials is arranged in the collecting component; The collection component includes a blanking pipe 14 fixedly connected between the calcination cylinder 11 and the conveying box 1 for conveying calcined materials. A screening cylinder 18 for collecting calcined materials is rotatably installed at the lower part of the blanking pipe 14; After the fluorite blocks in the main calcination area and the secondary calcination area in the calcination cylinder 11 are calcined, the remaining fluorite blocks and calcination waste generated will jointly fall through the blanking pipe 14 and be conveyed to the screening cylinder 18, thus completing the automatic conveying and collection of the calcination residues.

[0031] In a further embodiment, a driving mechanism is arranged in the crushing component. The driving mechanism is used to drive the screening cylinder 18 to rotate and cooperate with the crushing component to realize the crushing and grading of the calcined materials; The driving mechanism includes a servo motor 16 fixedly installed in the conveying box 1. A driving roller 19 is fixedly installed on the driving end of the servo motor 16. A transmission gear 20 is fixedly installed on the driving roller 19. A transmission tooth ring 25 is fixedly installed on the outside of the screening cylinder 18, and the transmission tooth ring 25 meshes with the transmission gear 20; When the servo motor 16 is started, it will drive the driving roller 19 to rotate. When the driving roller 19 rotates, it will drive the transmission gear 20 thereon to rotate. When the transmission gear 20 rotates, it will drive the transmission tooth ring 25 meshing with it to rotate, and then drive the screening cylinder 18 to rotate together.

[0032] When the calcined materials in the screening cylinder 18 are collected, the servo motor 16 can be started to drive the screening cylinder 18 to rotate under the cooperation of the transmission gear 20 and the transmission tooth ring 25. When the screening cylinder 18 rotates, it will drive the calcined materials therein to rotate together. When the calcined materials rotate, they will impact the inside of the screening cylinder 18 under the action of centrifugal force, and the softer calcination waste in the calcined materials can be impacted and broken during the impact, while the remaining fluorite blocks in the calcined materials cannot be broken, thus realizing the automatic crushing of the calcination waste and reducing the volume of the calcination waste.

[0033] The crushing component includes a plurality of swing spring shafts 27 fixedly installed in the screening cylinder 18. A swing plate is rotatably installed on each swing spring shaft 27, and a plurality of crushing parts 28 for impacting and crushing the calcined materials are fixedly installed on each swing plate; When the screening cylinder 18 rotates, it will drive the plurality of swing spring shafts 27 therein to rotate. When the swing spring shafts 27 rotate, they will drive the plurality of swing plates thereon to rotate together, and at the same time use the reset effect of the swing spring shafts 27 to realize automatic swinging, so as to realize the reciprocating swing of the swing plates while rotating, and thus drive the plurality of crushing parts 28 thereon to swing together.

[0034] A plurality of screening holes 24 for screening crushed slag are formed in the screening cylinder 18. While the crushing member 28 swings, it will impact the calcined waste inside the screening cylinder 18, which can further promote the crushing of the calcined waste during the impact process, and further reduce the volume of the calcined waste. When the screening cylinder 18 rotates, the calcined waste with a volume meeting the requirements after crushing will be thrown out through the screening holes 24 under the action of the rotational centrifugal force, while the remaining fluorite block materials with a larger volume will accumulate inside the screening cylinder 18, thus completing the automatic classification of the calcined waste and the remaining fluorite block materials in the calcined material.

[0035] In a further embodiment, a vibrating disk 29 and a conveying mechanism are arranged in the discharge assembly. The vibrating disk 29 reciprocates under the drive of the driving mechanism to realize the classification of the crushed calcined material, and cooperates with the conveying mechanism to realize the differential conveying of the classified calcined material. The discharge assembly includes a vibrating disk 29 slidably installed in the conveying cylinder 15. A plurality of filtering holes 30 for classifying the calcined material are formed in the vibrating disk 29. A transmission lead screw 32 is fixedly installed on the driving roller 19, and a lifting nut plate 33 is threadedly installed on the transmission lead screw 32. A vibrating rod 36 is fixedly installed between the lifting nut plate 33 and the vibrating disk 29. When the driving roller 19 rotates, it will drive the transmission lead screw 32 thereon to rotate. Since the lifting nut plate 33 is in threaded cooperation with the transmission lead screw 32, when the transmission lead screw 32 rotates, it will drive the lifting nut plate 33 to move vertically. That is, when the transmission lead screw 32 rotates forward, it will drive the lifting nut plate 33 to rise, and when the transmission lead screw 32 rotates reversely, it will drive the lifting nut plate 33 to move downward.

[0036] The calcined waste thrown out from the screening cylinder 18 will fall onto the upper part of the vibrating disk 29 in the conveying cylinder 15 and continue to fall through the plurality of filtering holes 30 thereon. After all the calcined material in the screening cylinder 18 is thrown out, the guide pipe 26 can be opened to make the remaining fluorite block materials in the screening cylinder 18 fall naturally onto the upper part of the vibrating disk 29.

[0037] When the servo motor 16 drives the driving roller 19 to rotate forward and backward, it will drive the transmission lead screw 32 to rotate reciprocally, and then drive the lifting nut plate 33 to reciprocally rise and fall. When the lifting nut plate 33 reciprocally rises and falls, it will drive the vibrating disk 29 to reciprocally rise and fall through the vibrating rod 36, that is, drive the vibrating disk 29 to perform lifting vibration. During the lifting vibration of the vibrating disk 29, the remaining fluorite block materials thereon can be vibrationally screened, and the remaining calcined waste attached to the fluorite block materials can be shaken off, so that the calcined waste falls through the filtering holes 30, realizing the complete separation of the fluorite block materials and the calcined waste. On the vibrating disk 29, there is a first discharge box 21 for discharging large-volume calcined materials. On the conveying box 1, there is a first discharge conveyor belt 8, and the first discharge conveyor belt 8 cooperates with the first discharge box 21. The remaining fluorite blocks after separation will be exported through the first discharge box 21 and conveyed through the first discharge conveyor belt 8, thus completing the automatic conveyance of the remaining fluorite blocks.

[0038] In a further embodiment, the conveying mechanism includes a chassis 23 fixedly installed at the bottom of the conveying barrel 15. There is a conveying groove 34 on the chassis 23. Two return springs 31 are fixedly installed between the chassis 23 and the vibrating disk 29. On the chassis 23, there is a second discharge box 22 for discharging calcined and crushed materials. On the conveying box 1, there is a second discharge conveyor belt 9, and the second discharge conveyor belt 9 cooperates with the second discharge box 22. The calcined waste materials falling through the filter holes 30 will fall into the conveying groove 34 on the chassis 23 and will be conveyed and exported through the second discharge box 22 to the second discharge conveyor belt 9, thus enabling the automatic conveyance of the calcined waste materials through the second discharge conveyor belt 9.

[0039] A rolling plate 35 is fixedly installed at the lower part of the vibrating disk 29. The rolling plate 35 cooperates with the conveying groove 34. A plurality of rolling rollers 37 are rotatably installed at the lower part of the rolling plate 35. When the vibrating disk 29 moves downward, it will drive the rolling plate 35 at its lower part to move downward. When the rolling plate 35 moves downward, it will drive the plurality of rolling rollers 37 thereon to press into the conveying groove 34, thus re-rolling the calcined waste materials in the conveying groove 34, further reducing the volume of the calcined waste materials and being more conducive to the automatic conveyance of the calcined waste materials.

[0040] The specific conveying principle of this conveying device is as follows: Place the fluorite block raw materials to be calcined on the feeding conveyor belt 3 and convey them to the inside of the calcining furnace 2 along with the feeding conveyor belt 3. Since the volumes of the fluorite block raw materials are different, the smaller-volume fluorite block raw materials will fall through the plurality of grading holes on the feeding conveyor belt 3 and fall onto the distributing conveyor belt 4 during the conveying process, thus realizing the automatic screening of the fluorite block raw materials according to the volume during the conveying process. The large-volume fluorite blocks on the feeding conveyor belt 3 will fall into the main calcining area inside the calcining barrel 11, and the small-volume fluorite blocks on the distributing conveyor belt 4 will fall into the secondary calcining area inside the calcining barrel 11. At this time, start the calcining barrel 11 to respectively conduct targeted high-temperature calcination on the fluorite block raw materials in the main calcining area and the secondary calcining area. During the calcination of the fluorite block raw materials in the main calcining area and the secondary calcining area of the calcining barrel 11, a certain amount of hydrogen fluoride gas will be generated. The gas generated in the main calcining area will enter the first exhaust pipe 12, and the gas generated in the secondary calcining area will enter the second exhaust pipe 13, thus realizing the automatic collection and conveyance of the gas generated during calcination.

[0041] After the fluorite blocks in the main calcination area and the secondary calcination area in the calcination cylinder 11 are calcined, the remaining fluorite blocks and calcination waste generated will jointly fall and be conveyed through the feeding pipe 14 into the screening cylinder 18, thus completing the automatic conveying and collection of the calcination residue.

[0042] After the calcination materials in the screening cylinder 18 are collected, the servo motor 16 is started. Under the combined action of the transmission gear 20 and the transmission gear ring 25, the screening cylinder 18 is driven to rotate. When the screening cylinder 18 rotates, it will drive the calcination materials inside it to rotate together. When the calcination materials rotate, they will impact the inside of the screening cylinder 18 under the action of centrifugal force, and thus the relatively soft calcination waste in the calcination materials can be impacted and broken during the impact process, while the remaining fluorite blocks in the calcination materials cannot be broken, thereby realizing the automatic crushing of the calcination waste to reduce the volume of the calcination waste. When the screening cylinder 18 rotates, the calcination waste with a volume meeting the requirements after being broken will be thrown out through the screening holes 24 under the action of the rotational centrifugal force, while the remaining fluorite blocks with a larger volume will accumulate inside the screening cylinder 18, thus completing the automatic classification treatment of the calcination waste and the remaining fluorite blocks in the calcination materials.

[0043] The calcination waste thrown out from the screening cylinder 18 will fall onto the upper part of the vibrating disk 29 in the conveying cylinder 15 and continue to fall through the multiple filter holes 30 on it. After all the calcination materials in the screening cylinder 18 are thrown out, the guide pipe 26 can be opened to make the remaining fluorite blocks in the screening cylinder 18 fall naturally onto the upper part of the vibrating disk 29. When the servo motor 16 drives the driving roller 19 to rotate forward and backward, it will drive the transmission lead screw 32 to rotate reciprocally, and then drive the lifting nut plate 33 to reciprocally lift. When the lifting nut plate 33 reciprocally lifts, it will drive the vibrating disk 29 to reciprocally lift through the vibrating rod 36, that is, drive the vibrating disk 29 to perform lifting vibration. During the lifting vibration of the vibrating disk 29, the remaining fluorite blocks on it can be vibrationally screened, and then the remaining calcination waste attached to the remaining fluorite blocks can be shaken off, so that the calcination waste falls through the filter holes 30, realizing the complete separation of the remaining fluorite blocks and the calcination waste. The separated remaining fluorite blocks will be exported through the discharge box one 21 and conveyed through the discharge conveyor belt one 8, thus completing the automatic conveying of the remaining fluorite blocks.

[0044] The calcination waste falling through the filter holes 30 will fall into the conveying groove 34 on the tray 23 and be conveyed and exported through the discharge box two 22 onto the discharge conveyor belt two 9, and thus the automatic conveying of the calcination waste can be carried out through the discharge conveyor belt two 9.

[0045] The embodiment of the present invention also provides an automatic conveying method for calcining fluorite block treatment, which is used for the above-mentioned automatic conveying device for calcining fluorite block treatment, and includes the following steps: S1. Convey the fluorite blocks to be calcined into the calcination cylinder 11 through the feeding unit, and start the calcination cylinder 11 to calcine the fluorite blocks; S2.
