Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of feeding devices, and relates to a movable ultrafine silicon powder pulping feeding device special for silicon powder method silicon sol. BACKGROUND

[0002] In the process of producing silicon sol by the silicon powder method, first, ultrafine silicon powder needs to be mixed with deionized water in a pulping device to make slurry. The ultrafine silicon powder is usually packaged and transported in ton bags. During the process of feeding the ultrafine silicon powder into the pulping device, the ton bag needs to be hoisted above the feeding port of the pulping device, the bottom discharge port of the ton bag is opened, and the silicon powder falls into the device by gravity. Because the particle size of the fine silicon powder is small and the specific surface area is large, adsorption and agglomeration phenomena are prone to occur between particles. In the ton bag, the silicon powder often forms a bridging or arching structure, causing the discharge to be interrupted or the flow rate to be unstable, and the silicon powder cannot fall quickly and continuously, affecting the feeding efficiency.

[0003] To solve the above problems, the application provides a movable ultrafine silicon powder pulping feeding device special for silicon powder method silicon sol. SUMMARY

[0004] To solve the problems in the background art, the application provides a movable ultrafine silicon powder pulping feeding device special for silicon powder method silicon sol.

[0005] To achieve the above purpose, the application adopts the following technical scheme:

[0006] A movable ultrafine silicon powder pulping feeding device special for silicon powder method silicon sol, comprising a transfer assembly, a mounting cylinder and a support assembly.

[0007] The mounting cylinder is mounted on the transfer assembly.

[0008] The support assembly comprises a swing rod, a pull rope and a support piece.

[0009] The support piece comprises a plurality of bearing plates, the plurality of bearing plates are sequentially connected end to end, and adjacent bearing plates are hinged through a hinge shaft. A through hole is arranged in the middle of the support piece. A swing rod is arranged above adjacent bearing plates, one end of the swing rod is rotationally connected to the mounting cylinder, and the other end of the swing rod is connected to the bearing plate below it through a pull rope. A hook for hooking the ton bag is mounted in the middle of the swing rod.

[0010] A driving assembly for driving the swing rod to rotate is mounted on the mounting cylinder.

[0011] The plurality of swing rods are sequentially rotated upward, so that the corresponding parts of the support piece are raised, and then the plurality of parts of the ton bag are sequentially shaken.

[0012] Further, the support member is square as a whole, and there are four bearing plates. The four bearing plates are circumferentially evenly distributed according to the axis of the mounting cylinder; the hinge shaft is arranged along the diagonal of the support member;

[0013] Correspondingly, there are four swing rods; the four swing rods are circumferentially evenly distributed along the axis of the mounting cylinder.

[0014] Further, the driving component includes a gear and a rack; a fixed shaft is fixedly connected to the swing rod, the fixed shaft is elastically rotatably connected to the mounting cylinder, a gear is fixedly installed on the fixed shaft, the gear meshes with the rack, and the rack is slidably arranged on the mounting cylinder;

[0015] A rotating ring is rotatably installed in the mounting cylinder, the rotating ring is connected with a top cone, and the upper end of the rack is provided with an arc surface; a driving motor for rotating the rotating ring is fixedly installed in the mounting cylinder.

[0016] Further, a lifting ring is arranged to move up and down in the mounting cylinder, and the rotating ring is rotatably installed on the lifting ring.

[0017] Further, the output shaft of the motor is fixedly connected with a spline shaft, and a spline groove cooperating with the spline shaft is formed on the rotating ring; the spline shaft extends into the rotating ring.

[0018] Further, two pulling ropes are connected to the end of the swing rod far away from the mounting cylinder, and the lower ends of the two pulling ropes are respectively connected to the corresponding two bearing plates.

[0019] Further, an avoidance groove is formed at a position corresponding to the gear on the mounting cylinder.

[0020] Further, the transfer component includes two longitudinally parallel slide rails, a sliding frame and a transverse slide rail; a sliding frame is slidably arranged on each longitudinally slide rail, a transverse slide rail is connected between the two sliding frames, a lifting component is slidably arranged on the transverse slide rail, and the upper end of the mounting cylinder is installed on the lifting component.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] During feeding, by rotating the rotating ring, the rotating ring drives the multiple swing rods to rotate in sequence through the top cone, so that multiple corners of the support member are sequentially tilted upward, and at the same time the corresponding suspension straps move upward and inward, so that multiple corners of the ton bag are sequentially turned upward and inward, which is beneficial to quickly dropping the ultrafine silicon powder in the ton bag and improving the feeding efficiency.

[0023] After the feeding is completed, by moving the rotating ring downward, the multiple swing rods swing reciprocally at the same time, and the swing rods drive the ton bag to shake rapidly, which is beneficial to making the ultrafine silicon powder remaining on the inner wall of the ton bag fall off, discharging the ultrafine silicon powder in the ton bag cleanly, and reducing waste.

[0024] The support components provide support to the ton bag, reducing the stress on the lifting straps and thus decreasing the probability of strap breakage. Furthermore, in the event of an accidental strap breakage, the support components prevent the ton bag from tilting and spilling the ultrafine silica powder inside. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1: As Figures 1-12 As shown, the technical solution adopted by the present invention is as follows: a movable ultrafine silicon powder slurry feeding device for silicon powder sol, comprising a transfer component, a mounting cylinder 5 and a support component.

[0040] like Figure 1 As shown, the transfer assembly includes a longitudinal slide rail 1, a sliding frame 2, and a transverse slide rail 3. There are two longitudinal slide rails 1, with two sliding frames 2 arranged in parallel. A sliding frame 2 is slidably mounted on each longitudinal slide rail 1, and the longitudinal slide rail 1 drives the corresponding sliding frame 2 to move. A transverse slide rail 3 connects the two sliding frames 2, and a lifting assembly 4 is slidably mounted on the transverse slide rail 3. The transverse slide rail 3 drives the lifting assembly 4 to slide along the transverse slide rail 3. The upper end of the mounting cylinder 5 is mounted on the lifting assembly 4. The lifting assembly 4 drives the mounting cylinder 5 to move up and down. The longitudinal slide rail 1, the transverse slide rail 3, and the lifting assembly 4 are all mature existing technologies and will not be described in detail here.

[0041] The support components include a swing arm 20, a pull rope 22, and a support member.

[0042] The support includes multiple bearing plates 23, which are connected end to end in sequence, and adjacent bearing plates 23 are hinged together by hinge shafts 25. Specifically, lugs 24 are fixedly connected to both sides of each bearing plate 23, and the lugs 24 between adjacent bearing plates 23 are hinged together by hinge shafts 25.

[0043] In this embodiment, the support member is generally square, and four bearing plates 23 are provided, which are evenly distributed around the circumference of the mounting cylinder 5. The hinge shaft 25 is arranged along the diagonal of the support member.

[0044] The support component has a through hole in the middle. When the ton bag is placed on the support component, the discharge pipe on the ton bag passes through the through hole to facilitate material discharge.

[0045] A rocker arm 20 is provided above the hinge shaft 25 between adjacent bearing plates 23. In this embodiment, four rocker arms 20 are provided, and the four rocker arms 20 are evenly distributed around the axis of the mounting cylinder 5.

[0046] One end of the swing arm 20 is rotatably connected to the mounting cylinder 5, and the other end of the swing arm 20 is connected to the supporting plate 23 below it via a pull rope 22. In this embodiment, each swing arm 20 has two pull ropes 22 connected to the end away from the mounting cylinder 5, and the lower ends of the two pull ropes 22 are respectively connected to the corresponding two supporting plates 23. That is to say, both sides of each supporting plate 23 are connected to the swing arm 20 via pull ropes 22.

[0047] A hook 21 for hanging ton bags is installed in the middle of the swing arm 20. The ton bag is placed on the support, and the four straps of the ton bag are hooked onto the four hooks 21 respectively.

[0048] The four swing arms 20 rotate upwards in sequence. Each swing arm 20 pulls the corresponding corner of the support component upwards via the pull rope 22. As the swing arms 20 rotate upwards, they also cause the corresponding lifting straps to move upwards, thereby causing the corresponding corners of the ton bag to flip upwards and inwards. By having the four swing arms 20 rotate upwards in turn, the four corners of the ton bag flip upwards and inwards sequentially, which facilitates the discharge of ultrafine silica powder from the ton bag through the discharge pipe.

[0049] The mounting cylinder 5 is equipped with a drive assembly that drives the rocker arm 20 to rotate. The drive assembly includes a gear 19 and a rack 14.

[0050] A rotating ring 8 is rotatably mounted inside the mounting cylinder 5, and a motor 11 that drives the rotating ring 8 to rotate is fixedly mounted inside the mounting cylinder 5.

[0051] A fixed shaft 18 is fixedly connected to the end of the swing arm 20 away from the pull rope 22. The fixed shaft 18 is rotatably mounted on the mounting cylinder 5. A torsion spring is sleeved on the fixed shaft 18, and the torsion spring is fixedly connected between the mounting cylinder 5 and the swing arm 20. The axis of the fixed shaft 18 is perpendicular to the axis of the mounting cylinder 5. A gear 19 is coaxially fixedly connected to the fixed shaft 18. A clearance groove 17 is provided on the mounting cylinder 5 at a position corresponding to the gear 19, and the gear 19 is disposed in the clearance groove 17.

[0052] Gear 19 meshes with rack 14. Rack 14 is slidably mounted inside mounting cylinder 5. Specifically, limit frames 13 are provided on both sides of rack 14, and the limit frames 13 are fixedly connected to mounting cylinder 5. Limit grooves 15 are provided on rack 14 to slide with limit frames 13, and one end of limit frame 13 is slidably mounted in the limit grooves 15. An arc surface 16 is provided at the upper end of rack 14. A top cone 10 is vertically fixed at the lower end of rotating ring 8. When rotating ring 8 drives top cone 10 to rotate, top cone 10 pushes rack 14 downward through arc surface 16. As rotating ring 8 rotates, top cone 10 pushes multiple racks 14 downward in sequence, thereby causing multiple rocker arms 20 to rotate upward in sequence.

[0053] Working principle: Initially, the upper end of rack 14 rests against rotating ring 8. The rocker arm 20 is in a horizontal state.

[0054] In use, the mounting cylinder 5 is moved to the loading position via the longitudinal slide rail 1 and the transverse slide rail 3. Then, the lifting assembly 4 lowers the mounting cylinder 5 so that the support contacts the ground. The mounting cylinder 5 is then lowered further, causing the pull rope 22 to slacken.

[0055] Next, the staff pulls the rope 22 outward to facilitate placing the ton bag containing ultrafine silicon powder onto the support, and to extend the discharge pipe at the bottom of the ton bag into the through hole. The lifting hook on the ton bag is then hooked onto the hook 21.

[0056] Then, the lifting assembly 4 moves the mounting cylinder 5 upward, which in turn moves the swing arm 20 upward. The swing arm 20 then moves the hook 21 and the pull rope 22 upward. Since the upper end of the rack 14 is pressed against the rotating ring 8, the rack 14 cannot move upward. The gear 19 meshes with the rack 14, keeping the swing arm 20 horizontal. The swing arm 20 pulls the ton bag up through the hook 21. Simultaneously, the swing arm 20 pulls the pull rope 22, keeping it taut. Because multiple swing arms 20 are horizontal, the pull ropes 22 exert the same tension on the support. This keeps the support horizontal and in contact with the bottom of the ton bag, providing support. If the sling suddenly breaks during the transfer, the ton bag will lose its tension due to the support, preventing it from tilting and thus avoiding accidental spillage of the ultrafine silica powder inside. Furthermore, since the support components provide some support to the ton bag, the stress on the slings is reduced, which helps to decrease the probability of sling breakage.

[0057] Next, the mounting cylinder 5 and the support assembly are moved above the ultrafine silica powder slurry preparation device via the longitudinal slide rail 1 and the transverse slide rail 3. Then, the discharge pipe of the ton bag is connected to the feed port on the ultrafine silica powder slurry preparation device. Then, the rope on the discharge pipe is untied, allowing the ultrafine silica powder in the ton bag to fall into the ultrafine silica powder slurry preparation device, thus enabling feeding.

[0058] During the feeding process, the motor 11 is started, the rotating ring 8 rotates, and the rotating ring 8 drives the top cone 10 to rotate. The top cone 10 pushes multiple racks 14 downward in sequence. When the racks 14 move downward, they drive the corresponding gears 19 to rotate. The gears 19 drive the corresponding swing rods 20 to rotate upward around the fixed shaft 18. The swing rods 20 drive the hooks 21 and the pull ropes 22 to move upward and towards the mounting cylinder 5. The swing rods 20 drive the corresponding corners of the support to tilt upward through the pull ropes 22. The corresponding two bearing plates 23 rotate around the corresponding hinge shafts 25, while the other two bearing plates 23 remain stationary. That is, one corner of the support rotates upward around the diagonal. At the same time, the hooks 21 pull the corresponding lifting straps upward. Under the action of the hooks 21 and the bearing plates 23, the corresponding corners of the ton bag move upward and inward, which is conducive to the rapid discharge of ultrafine silicon powder in the ton bag and improves the feeding efficiency. When the racks 14 disengage from the top cone 10, the swing rods 20 rotate downward around the fixed shaft 18, and the gears 19 drive the racks 14 to move upward. Until the rocker arm 20 and rack 14 are reset.

[0059] As the rotating ring 8 rotates, the top cone 10 pushes multiple racks 14 downward in sequence, causing multiple swing rods 20 to rotate upward in sequence, which in turn causes the corners of the ton bag to flip upward and inward in sequence, thereby allowing the ultrafine silicon powder inside the ton bag to flow out quickly and evenly, improving the feeding efficiency.

[0060] After feeding is completed, the rotating ring 8 continues to rotate, causing the corners of the support to flip upwards in sequence, which in turn causes the corners of the ton bag to flip upwards and inwards in sequence, causing the ton bag to shake. This helps to shake off the residual ultrafine silicon powder on the inner wall of the ton bag, allowing the residual ultrafine silicon powder in the ton bag to fall quickly into the discharge pipe and reducing the residue at the bottom of the ton bag.

[0061] Example 2: This example is an improvement based on Example 1.

[0062] A lifting ring 7 is installed inside the mounting cylinder 5, allowing it to move vertically. Specifically, multiple cylinders 6 are vertically mounted inside the mounting cylinder 5, with the telescopic ends of the cylinders 6 pointing vertically downwards. The mounting cylinder 5 is fixedly connected to the telescopic ends of the cylinders 6. A rotating ring 8 is rotatably mounted inside the lifting ring 7. The rotating ring 8 is coaxially arranged with the mounting cylinder 5. A spline groove 9 is formed in the middle of the rotating ring 8, and a spline shaft 12 is fitted inside the rotating ring 8. The output shaft of the motor 11 points vertically downwards and is fixedly connected to the upper end of the spline shaft 12. The motor 11 drives the rotating ring 8 to rotate via the spline shaft 12. When the cylinders 6 extend or retract, the rotating ring 8 moves vertically along the spline shaft 12. The motor 11 drives the spline shaft 12 to rotate.

[0063] The rotating ring 8 moves downward, causing the four swing arms 20 to rotate simultaneously up and down. When the swing arms 20 rotate upward, they drive the lifting straps of the ton bag to move upward and inward. When the swing arms 20 rotate downward, they drive the lifting straps of the ton bag to move downward and outward, thereby shaking the ton bag and dislodging the ultrafine silica powder adhering to the inner wall of the ton bag. This helps to completely remove the ultrafine silica powder from the ton bag.

[0064] After the ultrafine silicon powder in the ton bag is completely added, the motor 11 stops moving, the rotating ring 8 stops rotating, and when the motor 11 stops, the racks 14 are all abutting against the lower end face of the rotating ring 8, meaning that all the swing arms 20 are in a horizontal state. The cylinder 6 is activated, causing it to extend and retract rapidly. The cylinder 6 drives the lifting ring 7 and the rotating ring 8 to move up and down rapidly. When the rotating ring 8 moves down, it pushes the racks 14 downwards simultaneously, causing the swing arms 20 to rotate upwards simultaneously. When the rotating ring 8 moves upwards, under the action of the torsion spring, the swing arms 20 rotate downwards, and the gear 19 drives the racks 14 upwards. With the up-and-down reciprocating movement of the rotating ring 8, the swing arms 20 swing up and down simultaneously. The swing arms 20 cause the corresponding lifting straps to vibrate rapidly, causing the ultrafine silicon powder remaining on the inner wall of the ton bag to fall off. Furthermore, with the vibration of the ton bag, the ultrafine silicon powder inside quickly enters the discharge pipe and is discharged, reducing the residue of ultrafine silicon powder in the ton bag and minimizing waste.

[0065] When all four levers 20 rotate upwards simultaneously, multiple pull ropes 22 cause the support to move upwards. During installation, the discharge pipe can move upwards relative to the ultrafine silica powder slurry preparation device by a certain distance, or the discharge pipe can extend or retract, allowing the support to move upwards relative to the ultrafine silica powder slurry preparation device by a certain distance.

[0066] The rotating ring 8 can also be rotated at the same time, causing the top cone 10 to push multiple racks 14 downward in sequence, thereby causing the four corners of the support to flip upward in sequence, which helps the residual ultrafine silicon powder in the ton bag to fall quickly into the discharge pipe and reduce the residue of ultrafine silicon powder in the ton bag.

[0067] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
