Description

Technical Field

[0001] This utility model relates to the field of boron carbide processing and production technology, and specifically to an iron removal device for boron carbide processing. Background Technology

[0002] Boron carbide is an advanced ceramic material with high hardness, high melting point, and low density. It is widely used in bulletproof armor, abrasives, neutron absorbers in the nuclear industry, and its processing involves multiple steps.

[0003] In the prior art, such as the silicon carbide product micro-powder grinding mill with announcement number CN217249640U, there is a grinding mill body. A drive motor is installed on one side of the grinding mill body. A cleaning box is installed at the bottom of the grinding mill body. A discharge pipe is installed at the bottom of the grinding mill body. The discharge pipe is located inside the cleaning box. A rotating rod is installed inside the cleaning box. A cylindrical electromagnet is fixedly connected to the outside of the rotating rod. The other end of the rotating rod passes through the cleaning box and is rotatably connected to it. The rotating rod and the drive motor are provided with a transmission mechanism. A discharge pipe is installed at the bottom of the cleaning box.

[0004] In the above description, electromagnets can more effectively adsorb iron impurities, and the fine powder falling on the iron impurities will also fall off due to the rotation of the electromagnet, basically achieving the removal of iron. This demonstrates the impurity removal function of the device to a certain extent. However, after reading the technical solution, it is found that the main component for removing iron is the cylindrical electromagnet. Since the material is continuously discharged from the discharge pipe, as the electromagnet rotates around the circumference with the rotating rod, a part of the surface can directly adsorb iron after contacting the material, but the other part of the surface will cause the iron to fall off under the combined action of centrifugal force and gravity, resulting in poor impurity removal effect. Further investigation reveals that the accumulation of material on the surface of the electromagnet is also an objective reason for the uneven adsorption force of the electromagnet. Therefore, the material can be flattened and spread out to reduce the probability of material accumulation, making the electromagnet's ability to adsorb iron more uniform and comprehensive. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an iron removal device for boron carbide processing, which can effectively solve the problems in the existing technology where part of the electromagnet will fall off under the combined action of centrifugal force and gravity, and the poor iron attraction effect caused by the material falling too fast.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an iron removal device for boron carbide processing, including a processing cylinder. A feeding tray is adapted to be installed at the bottom of the processing cylinder. A material unloading component is fitted to the feeding tray. The material unloading component includes a straight pipe communicating with the surface of the feeding tray. A first suction stone is fixed to the inner wall of the straight pipe. A unloading ball is inserted into the side of the first suction stone. A spiral pipe is connected to the bottom of the straight pipe. The bottom of the first suction stone is aligned with the bottom of the spiral pipe. An iron removal component is fitted to the spiral pipe. A ring disk is corresponding to the bottom opening of the spiral pipe. A second suction stone is fixed to the inner wall of the ring disk. A rotating ring component is fitted to the ring disk.

[0008] The rotating ring component includes an internal tooth located at the bottom of the ring disk. The teeth of the internal tooth mesh with a spur gear. The spur gear is fixed to a drive source via its own adapter shaft. A timing belt is sleeved on the outer surface of the adapter shaft. The timing belt is coupled with a transmission component and a flattening component.

[0009] Furthermore, a material passage hole is provided at the bottom of the ring disc, and a roller is slidably contacted on the outer wall surface of the ring disc. A material collection cylinder is fixed to the roller through a symmetrical seat, and multiple sets of frames are fixedly connected to the outer side of the material collection cylinder.

[0010] Furthermore, the spiral tube is a one-piece molded tube, and the inner wall of the spiral tube is covered with a smoothing layer.

[0011] Furthermore, the number of the second magnets is several, and the distribution of the several second magnets is a ring array.

[0012] Furthermore, the annular disk is conical in shape, and the material passage holes are concentrated at the center of the annular disk.

[0013] Furthermore, the transmission component includes a insert shaft, the outer surface of which is sleeved with the top of the timing belt, and a main bevel gear is fixed to the end face of the insert shaft, with a secondary bevel gear meshing with the tooth surface of the main bevel gear.

[0014] Furthermore, a positioning post is provided on the top of the secondary bevel gear, a base plate is provided on the top of the positioning post, and the side of the base plate is fixed to multiple frames.

[0015] Furthermore, the flattening component includes a connecting rod portion, one end of which is fixed to a positioning post, and the other end of which is rotatably connected to a push block.

[0016] Furthermore, a sliding frame is slidably fitted on the outer side of the push block, a right-angle block is fixed at the bottom of the push block, and a flattening ball is inserted into the bottom of the right-angle block. The displacement stroke of the flattening ball is consistent with the radius of the ring disk.

[0017] Beneficial effects

[0018] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0019] 1. By adapting the processing cylinder and the feeding tray, boron carbide material can be continuously filled. A first suction stone is installed on the inner wall of the straight pipe, with a clearing ball inserted into its side. This allows for thorough adsorption and removal of iron from the boron carbide material while it falls smoothly, solving the problem of insufficient contact between the magnetic components and the material and improving adsorption efficiency. Simultaneously, a spiral tube is connected to the bottom of the straight pipe, allowing the material to be transported spirally within the tube. The spiral shape also slows the material's descent, indirectly ensuring full contact between the material and the first suction stone. Aligning the first suction stone with the inner wall of the spiral tube increases its adsorption range, resulting in better adsorption of iron and solving the problem of material falling during adsorption. Furthermore, a second suction stone is fixedly installed on the inner wall of the ring disc. After the iron in the material is adsorbed by the first suction stone, it is adsorbed again by the second stone. Through multiple adsorption processes, the problem of iron failing to be adsorbed after falling is solved, and the adsorption performance of the second suction stone is indirectly enhanced.

[0020] Second, by setting internal teeth at the bottom of the ring disk and meshing the internal teeth with spur gears, the ring disk rotates and generates centrifugal force. The centrifugal force pushes the material entering the ring disk to adhere to its inner wall, thereby reducing the accumulation of material at the bottom opening of the spiral tube and creating the prerequisite for the subsequent full adsorption of iron by the second adsorbent stone.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] See attached document Figure 1-5 A boron carbide processing iron removal device includes a processing cylinder 1, a feeding tray 11 adapted to be installed at the bottom of the processing cylinder 1, a material unloading assembly 2 fitted to the feeding tray 11, the material unloading assembly 2 including a straight pipe 21 connected to the surface of the feeding tray 11, a first suction stone 22 fixed to the inner wall of the straight pipe 21, a unloading ball 23 inserted into the side of the first suction stone 22, and a spiral pipe 24 connected to the bottom of the straight pipe 21, the bottom of the first suction stone 22 being aligned with the bottom of the spiral pipe 24, an iron removal assembly 3 fitted to the spiral pipe 24, and an annular disc 31 corresponding to the bottom opening of the spiral pipe 24, a second suction stone 32 fixed to the inner wall of the annular disc 31, and a rotating ring 37 fitted to the annular disc 31;

[0031] Among them, the rotating ring 37 includes an internal tooth 371 disposed at the bottom of the ring disk 31, the teeth of the internal tooth 371 meshing with a spur gear 372, the spur gear 372 being fixed with a drive source 373 through its own adapter shaft, the outer surface of the adapter shaft being fitted with a synchronous belt 374, and the synchronous belt 374 being fitted with a transmission component 38 and a flattening component 39.

[0032] By adapting and installing the processing cylinder 1 and the feeding tray 11, boron carbide material can be continuously filled. A first suction stone 22 is installed on the inner wall of the straight pipe 21, and a cleaning ball 23 is inserted into the side of the first suction stone 22. This allows for sufficient adsorption and removal of iron from the material while ensuring the smooth falling of the boron carbide material. This solves the problem of insufficient contact between the magnetic components and the material, improving the efficiency of adsorption and removal. It is worth noting that the first suction stone 22 is connected to an external power source. When the material quantity is large, the first suction stone 22 is not energized and loses its adsorption effect on iron in the material. The material is then transferred to the inner cavity of the spiral tube 24. When the material quantity is small, the first suction stone 22 is energized and generates magnetic force, which can perform the first adsorption of iron in the material. The adsorption process reduces the problem of material clogging the straight pipe 21. At the same time, a spiral tube 24 is connected to the bottom of the straight pipe 21. The spiral shape can also slow down the falling speed of the material, indirectly ensuring that the material can fully contact the first adsorbent stone 22. The first adsorbent stone 22 is aligned and set on the inner wall of the spiral tube 24, which undoubtedly increases the adsorption range of the first adsorbent stone 22 and has a better adsorption effect on iron in the material. This solves the problem of material falling during adsorption. Meanwhile, a second adsorbent stone 32 is fixedly set on the inner wall of the ring disk 31. After the iron in the material is adsorbed by the first adsorbent stone 22, it can be adsorbed again by the second adsorbent stone 32. Through multiple adsorptions to remove impurities, the problem of iron that cannot be adsorbed after falling is solved, and the adsorption performance of the second adsorbent stone 32 is indirectly enhanced.

[0033] By setting an internal tooth 371 at the bottom of the ring disk 31 and meshing the internal tooth 371 with the spur gear 372, the ring disk 31 rotates and generates centrifugal force. The centrifugal force pushes the material entering the ring disk 31 to adhere to its inner wall, thereby reducing the accumulation of material at the bottom opening of the spiral tube 24. This creates the prerequisite for the second suction stone 32 to fully adsorb iron. Furthermore, by fixing the spur gear 372 with the drive source 373 and cooperating the synchronous belt 374 with the transmission component 38 and the flattening component 39, the drive source 373 can directly provide power to the spur gear 372, helping the spur gear 372 to rotate continuously. This ensures that the iron in the material on the inner wall of the ring disk 31 is always tightly adhered to the second suction stone 32, making the iron removal process more efficient.

[0034] The bottom of the ring disk 31 is provided with a material passage hole 33, and the outer wall surface of the ring disk 31 is in sliding contact with a roller 34. The roller 34 is fixed with a material collection cylinder 35 through a symmetrical seat, and multiple sets of frames 36 are fixedly connected to the outside of the material collection cylinder 35.

[0035] By opening a material passage hole 33 at the bottom of the ring disk 31, the material after impurity removal can be discharged in time, making it convenient for the material to be stored in the collection cylinder 35. Then, the contact between the roller 34 and the outer wall of the ring disk 31 can provide rotational support for the ring disk 31, helping the rotation of the ring disk 31 to be more stable, further improving the adhesion of the material, preventing the material from splashing, and ensuring a relatively stable impurity adsorption effect of the second suction stone 32.

[0036] The spiral tube 24 is a one-piece molded tube, and the inner wall of the spiral tube 24 is covered with a smoothing layer 25;

[0037] By attaching a smoothing layer 25 to the inner wall of the spiral tube 24, the material will not adhere excessively to the inner wall of the spiral tube 24, reducing material residue and allowing the material to come into full contact with the first suction stone 22, thus fully realizing the impurity removal function.

[0038] The number of second magnets 32 is several, and the distribution of the several second magnets 32 is a ring array;

[0039] By using the second absorber 32 arranged in a ring array, the range of iron adsorption is significantly expanded, solving the problem of low impurity removal efficiency and achieving the additional effect of uniform impurity removal.

[0040] The ring disk 31 is conical in shape, and the material passage holes 33 are concentrated at the center of the ring disk 31.

[0041] By opening a material passage hole 33 at the center of the ring disk 31, the material can fall quickly in the middle after being cleaned of impurities, thus avoiding the accumulation of material and affecting the efficiency of iron impurity removal.

[0042] The transmission component 38 includes a shaft 381, the outer surface of which is sleeved with the top of the timing belt 374, and a main bevel gear 382 is fixed on the end face of the shaft 381, with a secondary bevel gear 383 meshing with the tooth surface of the main bevel gear 382.

[0043] Through the transmission cooperation of the insert shaft 381, main bevel gear 382, ​​auxiliary bevel gear 383 and synchronous belt 374, the rotational power is continuously transmitted, providing the source power for the subsequent pushing and rolling of materials.

[0044] The top of the secondary bevel gear 383 is provided with a positioning post 384, the top of the positioning post 384 is provided with a base plate 385, and the side of the base plate 385 is fixed to the multi-frame 36.

[0045] A positioning pin 384 is provided on the top of the secondary bevel gear 383 to ensure that the rotation of the secondary bevel gear 383 remains self-stabilized and the transmission process continues completely.

[0046] The flattening component 39 includes a connecting rod portion 391, one end of which is fixed to the positioning post 384, and the other end of which is rotatably connected to a push block 392.

[0047] The hinged rotational force of the connecting rod 391 is further transmitted to the push block 392 through the rotational connection of the connecting rod 391, which helps the push block 392 to achieve displacement movement.

[0048] The outer side of the push block 392 is slidably fitted with a sliding frame 393, and the bottom of the push block 392 is fixed with a right-angle block 394. A flattening ball 395 is inserted into the bottom of the right-angle block 394, and the displacement stroke of the flattening ball 395 is consistent with the radius of the ring disk 31.

[0049] The sliding engagement between the push block 392 and the slide frame 393 allows the push block 392 to move horizontally, with the direction of displacement being flush with the inner side of the slide frame 393, resulting in more stable displacement. Furthermore, right-angled blocks 394 and flattening balls 395 are sequentially installed at the bottom of the push block 392, enabling the flattening balls 395 to also move horizontally. The material in the annular disc 31 is crushed by the flattening balls 395 and pushed to the material passage hole 33, facilitating rapid material discharge.

[0050] Working principle: First, the boron carbide raw material is poured into the processing cylinder 1 and processed. The processed raw material falls through the feeding tray 11.

[0051] After the above, the raw material is introduced into the inner cavity of the straight pipe 21. The first suction stone 22 and the clearing ball 23 set on the inner wall of the straight pipe 21 can adsorb and remove the iron in the raw material for the first time. Then the raw material flows again into the spiral pipe 24 connected to the straight pipe 21. The spiral structure can avoid excessive accumulation of material. Then it flows out from the bottom port of the spiral pipe 24 and sprinkles into the ring disk 31.

[0052] At the same time, the drive source 373 is activated, and the drive source 373 gives the spur gear 372 rotational force, so that the spur gear 372 meshes with the internal teeth 371 set at the bottom of the ring disk 31, causing the ring disk 31 to rotate continuously. The centrifugal force generated by the rotation of the ring disk 31 will cause the raw material to stick to the inner wall surface. The second adsorbent 32, which is fixedly connected to the inner side of the ring disk 31, can perform a second comprehensive adsorption of iron in the raw material.

[0053] The adapter shaft of the spur gear 372 transmits rotational force to the insert shaft 381 through the transmission of the synchronous belt 374, which further causes the main bevel gear 382 to rotate actively. Through tooth meshing, the auxiliary bevel gear 383 is driven to rotate continuously. The rotation of the auxiliary bevel gear 383 causes the connecting rod 391 to move hingedly around the positioning pin 384. Then the connecting rod 391 causes the push block 392 to slide along the slide frame 393, which ultimately causes the flattening ball 395 to move and flatten along the radial direction. This significantly reduces the material accumulation on the inner wall of the ring disc 31 and allows the material to concentrate in the material passage hole 33 and fall into the collection cylinder 35.

[0054] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
