Technical field
The utility model relates to casting processing equipment technical field, is specifically related to a kind of recycling cast waste sand drying unit.
Background technology
Along with the development of industrial technology, Casting Technology have also been obtained widespread use, and China also creates a large amount of cast waste sands while casting industry develop rapidly. At present, except a small amount of recycling cast waste sand reuse, major part is to be discarded as master, and significant wastage limited resources, cause severe contamination to environment. In prior art, the regeneration and drying device operation of cast waste sand is loaded down with trivial details, it is easy to blocking, thermo-efficiency is low, and the reuse sand particle after oven dry is uneven, and dries quantity can not be guaranteed.
Practical novel content
The utility model is intended to provide a kind of recycling cast waste sand drying unit, it is possible to improve the thermo-efficiency of drying unit, and structure is simple, not easily blocks, can ensure dries quantity.
For achieving the above object, base case of the present utility model is as follows: recycling cast waste sand drying unit, comprise feeding machine and connect the bucket elevator of feeding machine, the lower section of described bucket elevator is provided with stoving oven, connected by the travelling belt that is obliquely installed between bucket elevator and stoving oven, the drying shed placing antiquated sand it is provided with in described stoving oven, a side bottom at drying shed is provided with discharge port, the vibratory screening apparatus of inclination it is provided with in the lower section of discharge port, the lower section of described vibratory screening apparatus is provided with blanking box, the side of described stoving oven is provided with combustion chamber, described combustion chamber is provided with hot gas transport pipe, hot gas transport pipe is communicated to the top of stoving oven, described hot gas transport pipe is provided with multiple lateral, lateral is provided with gas ejector pipe.
The principle of this base case is: when reality uses, cast waste sand to be dried is sent to bucket elevator by feeding machine, cast waste sand is transported in stoving oven by the travelling belt being obliquely installed by bucket elevator, now, stoving oven combustion chamber operational on one side, the type of thermal communication produced crosses the drying shed that hot gas transport pipe is transported in stoving oven, undertaken jet by the gas ejector pipe on multiple laterals of installation on hot gas transport pipe, hot gas flow disperses in drying shed, thus the cast waste sand in drying shed is dried, the discharge port of one side bottom of the cast waste sand drying room after oven dry is discharged, on the vibratory screening apparatus of blanking below discharge port, vibratory screening apparatus works, cast waste sand is carried out fragmentation and screening, finally drop in blanking box, also it is convenient to centralized recovery utilize, the utility model structure is simple, simple operation, not easily block, working process safety and stability, and thermo-efficiency improves greatly, reuse sand uniform particles after oven dry, dries quantity is ensured.
Preferred version 1: based on a kind of improvement of scheme, the outside of described gas ejector pipe is equipped with to be arranged on leads wind scoop on stoving oven inwall, the circulation of hot gas flow in stoving oven can be strengthened by leading wind scoop, to the oven dry thermo-efficiency height of antiquated sand in stoving oven, good drying effect.
Preferred version 2: preferably a kind of improvement of 1, described stoving oven is provided with venting hole, can guarantee the security of whole device in drying course.
Preferred version 3: preferably a kind of improvement of 2, the discharge outlet bottom drying shed is provided with control valve, can be opened by discharge port by control valve or the regulation and control of closing condition, practical.
