Description

Technical Field

[0001] The invention belongs to the technical field of silicon mud processing, and in particular relates to an automatic unloading device for silicon mud after drying. Background Art

[0002] Silica mud is a material composed of diatom mud, which is mainly used to smelt metallic silicon. However, due to its high water content and fine particles, the yield of metallic silicon smelted in an electric furnace is less than 20%. Most of the raw materials are easily oxidized or form other impurities such as silicon oxide, so the silica mud needs to be dried.

[0003] At present, a Chinese invention with the announcement number CN114812131B discloses a heat-recyclable silicon mud drying device. When the silicon mud is put into the dryer, the silicon mud will accumulate inside the dryer drum due to untimely transportation and uneven addition, which will affect the efficiency of heat transfer to the inside of the silicon mud, making it impossible for the silicon mud accumulated inside to completely dry the internal moisture, which will reduce the drying effect of the silicon mud. At the same time, the wet silicon mud will solidify together due to moisture, so even after the silicon mud is dried, the silicon mud will adhere together to form lumps, and the silicon mud at the front end cannot be quickly discharged from the inside of the dryer. The continuous addition of silicon mud at the back end will easily cause blockage inside the drum of the dryer, thereby reducing the feeding speed of the silicon mud, and then directly affecting the drying efficiency of the silicon mud. Even if the addition of silicon mud is stopped, it will affect the drying of the silicon mud. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic unloading device for silicon mud after drying, which has the advantage of reducing the amount of silicon mud inside the cylinder to avoid excessive silicon mud causing uneven heat transfer, thereby reducing the drying effect. At the same time, the drying efficiency of the silicon mud will not be reduced, and the dried silicon mud can be ground to avoid agglomeration and blockage caused by the silicon mud, thereby ensuring the unloading efficiency of the silicon mud.

[0005] The above technical purpose of the present invention is achieved through the following technical scheme: an automatic unloading device for silicon mud after drying, comprising a fixed base, a drying cylinder bolted to the top of the fixed base, a driving motor bolted to one end of the outside of the drying cylinder, a rotating inner cylinder connected to the inside of the drying cylinder, and a mobile drying mechanism installed inside the rotating inner cylinder.

[0006] By adopting the above technical solution, the silicon mud containing water is added to the four drying barrel grooves respectively, so that the rotating column can rotate to drive the second auger to separate and force the silicon mud containing water to be transported and dried. Thereby, the amount of silicon mud inside the barrel can be reduced to avoid uneven heat transfer caused by excessive silicon mud, thereby reducing the drying effect. At the same time, the four drying barrel grooves will not reduce the drying efficiency of silicon mud. By moving the dried silicon mud to the inside of the unloading barrel groove, the conveying shaft can drive the first auger to rotate and move the dried silicon mud out of the dryer. At the same time, the conical abrasive column can grind the dried silicon mud. Thereby, the silicon mud is prevented from agglomerating and clogging, and the unloading efficiency of the silicon mud is guaranteed.

[0007] The present invention is further configured as follows: the mobile baking mechanism includes a lower material barrel groove opened at the center of the rotating inner cylinder, four baking material barrel grooves are also opened inside the rotating inner cylinder, and the four baking material barrel grooves are symmetrically distributed on the surface of the lower material barrel groove, and the end of the rotating inner cylinder surface away from the driving motor is opened with a feeding slot that is separately connected to the four baking material barrel grooves, and the end of the four baking material barrel grooves away from the feeding slot is opened with a connecting slot connected to the lower material barrel groove. The output end of the driving motor is bolted with a third bevel gear rotatably connected to the fixed base, and the side of the fixed base close to the driving motor is rotatably connected with the second bevel gear meshing with the third bevel gear. The end of the rotating inner cylinder close to the driving motor is bolted with a first bevel gear meshing with the second bevel gear. The four baking material barrel grooves are all rotatably connected with a rotating column, and the surface of the rotating column is fixedly sleeved with a second auger, and the end of the rotating column close to the driving motor is fixedly sleeved with a first disc gear, and the side of the fixed base close to the driving motor is bolted with a second disc gear meshing with the first disc gear.

[0008] By adopting the above technical solution, the amount of silicon mud inside the drum can be reduced to avoid excessive silicon mud causing uneven heat transfer, thereby reducing the drying effect. At the same time, the synchronization of the four drying drum slots will not reduce the drying efficiency of the silicon mud.

[0009] The present invention is further configured as follows: one end of the third bevel gear away from the driving motor is bolted to a conveying shaft that is rotatably connected to the discharge barrel groove, a first auger is fixedly sleeved on the surface of the conveying shaft, the spiral directions of the first auger and the second auger are opposite, and one end of the conveying shaft away from the driving motor is bolted to a conical abrasive column that is slidably connected to the inner wall of the discharge barrel groove.

[0010] By adopting the above technical solution, the dried silicon mud can be ground to avoid agglomeration of the silicon mud, prevent blockage, and ensure the discharge efficiency of the silicon mud.

[0011] The present invention is further configured as follows: a feeding funnel connected to the feeding slot is bolted to one side of the top of the fixed base, and a movable cover is hinged to one side of the top of the feeding funnel.

[0012] By adopting the above technical solution, it is convenient to evenly add silicon mud to the inside of the four drying barrel grooves, and the feeding funnel can be covered when not in use to prevent dust and impurities from entering the inside.

[0013] The present invention is further configured as follows: a heat preservation sleeve is fixedly sleeved on the surface of the fixed base, an electric heater which is slidably sleeved on the surface of the rotating inner sleeve is bolted inside the heat preservation sleeve, and a control box electrically connected to the electric heater is bolted on one side of the outside of the heat preservation sleeve.

[0014] By adopting the above technical solution, the electric heater is turned on by the control box to heat the surface of the rotating inner cylinder, so that the silicon mud containing moisture inside the drying cylinder groove can be dried. At the same time, the heat preservation cylinder sleeve can reduce the speed of heat flowing from the surface of the fixed base and improve the heating efficiency.

[0015] The present invention is further configured as follows: the rotating inner cylinder is fixedly sleeved with a metal heat-conducting cylinder used in conjunction with an electric heater, and a sealing sleeve is fixedly sleeved at one end of the rotating inner cylinder surface close to the feed slot.

[0016] The above technical solution improves the heat absorption effect of the rotating inner cylinder surface, thereby improving the drying efficiency of silicon mud. The sealing sleeve can improve the sealing between the rotating inner cylinder and the fixed base to prevent silicon mud from leaking from the feed slot and the feeding funnel.

[0017] The present invention is further configured as follows: a wear-resistant lining plate slidably sleeved with the conical abrasive column is bolted to one side of the lower barrel groove near the conical abrasive column, and the inner surface of the wear-resistant lining plate and the outer surface of the conical abrasive column are both provided with grooves.

[0018] By adopting the above technical solution, the wear resistance of the inner part of the lower barrel groove and the conical abrasive column is increased, the service life is improved, and the grinding effect of silicon mud is guaranteed.

[0019] The present invention is further configured as follows: a discharge pipe opening is welded to one end of the rotating inner cylinder away from the driving motor and is rotatably connected to the fixed base.

[0020] The above technical solution is adopted to facilitate the discharge of the dried powdered silicon mud from the interior of the rotating inner drum, thereby ensuring the discharge efficiency.

[0021] The present invention is further configured as follows: an air blowing fan bolted to the rotating column is arranged at one end of the first disc gear away from the second auger, and mutually communicating air vents are arranged at both ends of the fixed base and the rotating inner cylinder.

[0022] By adopting the above technical solution, the blowing fan is driven to rotate synchronously when the rotating column rotates, so that the hot steam dried by the silicon mud inside the drying barrel groove can be blown out through the vent hole.

[0023] The present invention is further configured such that a filter screen is bolted inside the vent hole.

[0024] By adopting the above technical solution, the incoming air is filtered to prevent dust and impurities from entering the interior of the rotating inner cylinder through the vent holes.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. By adding the silicon mud containing water into the four drying barrel grooves respectively, the rotating column can rotate to drive the second auger to separate and force the silicon mud containing water to be transported and dried. This can reduce the amount of silicon mud inside the barrel to avoid excessive silicon mud causing uneven heat transfer, thereby reducing the drying effect. At the same time, the four drying barrel grooves will not reduce the drying efficiency of silicon mud when the silicon mud is treated synchronously;

[0027] 2. The dried silicon mud moves into the feeding barrel trough, so that the conveying shaft can drive the first auger to rotate and move the dried silicon mud out of the dryer. At the same time, the conical abrasive column can grind the dried silicon mud. This avoids the silicon mud from agglomerating and blocking, and ensures the silicon mud feeding efficiency.

[0048] Brief description of the use process: First, the third bevel gear 507 is driven to rotate by turning on the driving motor 3, so that the third bevel gear 507 drives the conveying shaft 508 to rotate clockwise, and at the same time, the third bevel gear 507 is meshed with the second bevel gear 506 for transmission, so that the rotating inner cylinder 4 can rotate counterclockwise after the first bevel gear 505 is meshed with the second bevel gear 506. Then, silicon mud containing water is added to the interior of the drying barrel groove 502 through the feeding funnel 6, and the silicon mud containing water can be added to different drying barrel grooves 502 by rotating the inner cylinder 4, so that the silicon mud containing water is dispersed for drying.

Since the spiral directions of the second auger 511 and the first auger 509 are opposite, the silicon mud can be conveyed in the opposite direction when rotating in the same direction, so that the silicon mud containing moisture inside the second auger 511 is heated by turning on the electric heater 10 to heat the surface of the rotating inner cylinder 4, and the rotating inner cylinder 4 dries the silicon mud conveyed inside the drying barrel groove 502 during the continuous rolling process, and conveys it to the inside of the lower barrel groove 501 through the connecting notch 504. Finally, the dried and agglomerated silicon mud is transported to the surface of the conical abrasive column 513 through the first auger 509, so that the conical abrasive column 513 rubs against the inner surface of the material discharge barrel groove 501 during the rotation process, thereby grinding the silicon mud, thereby facilitating the automatic discharge of the dried silicon mud. At the same time, the rotating column 510 rotates synchronously to drive the blowing fan 17 to rotate, so that the steam generated by the silicon mud drying inside the drying barrel groove 502 can be blown out through the vent hole 15.
