Description
Technical field
The utility model relates to silicon carbide micro-powder production facilities, especially a kind of feed bin discharger for carborundum granularity sand.
Background technology
Carborundum granularity sand claims again silicon carbide sand, carborundum subhead sand, is generally divided into 8#～320#, and model is larger, and granularity is thinner.Carborundum granularity sand is divided into two kinds of green and black, is desirable abrasive material, is widely used in grinding materials and grinding tool industry.The carborundum of particle diameter within the scope of 0.5～5mm is called granularity sand, be the raw MAT'L of silicon carbide micro-powder, and silicon carbide micro-powder is the desirable line cutting blade material of solar power crystal silicon chip, quartz conductor.
Feed bin is conventional equipment in silicon carbide micro-powder processing process, is also the storage facilities of other various loose powder body materials, mainly plays the effects such as relay storage, material buffer transition, or for delivery of material, with the continuity that guarantees to produce.The top of feed bin is cylindrical or prismatic mostly, and bottom is punctured into the conical hopper that has discharge port, and in storehouse, material draws off transhipment by deadweight from bottom discharge openings.In silicon carbide micro-powder process of manufacture, need to be by particle diameter the carborundum granularity sand within the scope of 0.5～5mm by coarse crushing workshop, by equipment such as bucket elevator, band conveyors, be transported to workshop in small, broken bits and carry out fining-off, must use many feed bins and granularity sand is carried out to gentle the breaking through of relay storage cross.Therefore, whether the design of discharger rationally directly has influence on the production efficiency that granularity sand is carried.
In prior art, bin bottom adopts sphere base to seal more, at bin bottom, welds a bolt, sphere base is carried out hinged, during discharging, by lower handle, moves, and making sphere base is that rotate in the center of circle along bolt, opens material outlet and carries out blowing.
Shortcoming is: sphere base and the accuracy requirement of material outlet junction are higher, processing inconvenience.Hinge bolt is inner at feed bin, for a long time in the high material of hardness, moves, and easily weares and teares, and causes poorly sealedly, affects the production efficiency of granularity sand.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, sealing is tight, reliable operation, can greatly enhance productivity, the economical and practical feed bin discharger for carborundum granularity sand.
The utility model discloses a kind of feed bin discharger for carborundum granularity sand, it is characterized in that comprising cylinder 1, cylinder 1 lower end is the lower cone 13 that opening is gradually little, at cylinder, 1 upper end open place is provided with support 5, the center of support 5 is provided with centralized positioning cover 6, centralized positioning cover 6 is provided with knock hole 14, in described knock hole 14, be provided with guide rod 7, guide rod 7 upper ends are connected with suspension ring 9 by pin 8, guide rod 7 is provided with keyway 10, guide rod 7 lower ends are provided with cone cap 3, Open Side Down for described cone cap 3, from bottom, stretch into lower cone 13, be set in the lower end of suspension rod 7, the outer wall of cone cap 3 is fastened on lower cone 13 opening edge edges.Support and bracing frame can utilize square steel to make.
Described support 5 belows are preferably provided with bracing frame 4.
The periphery, lower edge of described lower cone 13 is preferably provided with reinforced rib II 12.
Described cylinder 1 periphery, lower edge is preferably provided with reinforced rib I 2.
Described guide rod 7 inserts cone cap 3 tops from top to bottom, by the nut being installed on guide rod 7, tightens fixing.
The utility model adopts sloped footing to seal carborundum granularity sand, is that guide rod is pressed on discharging opening place at the bottom of by cone and seals material stock in feed bin inside by a main shaft.When needs carry out discharging, suspension ring place, upper end rope is loosening, sliding under cone, start blowing.
This discharger is owing to having used centralized positioning cover and support, and its center is accurate, in use there will not be the situation of disalignment, can control material lowering velocity, is particularly suitable for the discharging of the granular material of particle diameter within the scope of 0.5～5mm.Because the particle diameter of carborundum granularity sand is within the scope of 0.5～5mm, so use this discharger to carry out discharging, can obviously enhance productivity, reduce maintenance of equipment rate.
The utility model is rational in infrastructure, sealing is tight, reliable operation, can greatly enhance productivity, the economical and practical feed bin discharger for carborundum granularity sand.
