Description
Technical field
The invention belongs to hot investment casting field, be specifically related to wax-pattern in a kind of shell process processed and drench sand machine.
Background technology
In the silicon sol casing process of hot investment casting, need be stained with one deck sand after wax-pattern is stained with slurry on its surface, this operation now general pouring in sand device at wax-pattern is carried out.It is box structure that the wax-pattern of prior art drenches sand device, above casing, be provided with sandbox.During use, be transported to by sand in sandbox, sand falls bottom sandbox, and part sand drops on the wax-pattern surface in casing below sandbox, realizes drenching sand.The wax-pattern pouring sand apparatus structure of prior art is simple, be easy to realize, but the defect of also existing, sand can only fall from above, adhere on wax-pattern, although wax-pattern rotates in casing, wax-pattern surface still has some areas can not scab fully, make wax-pattern surface scab uneven, silicon sol casing is had a negative impact.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of hot investment casting wax-pattern surface layer drenching sand uniformity that can significantly improve and drench sand machine.
The present invention is achieved through the following technical solutions technical goal.
Hot investment casting wax-pattern surface layer drenches sand machine, and its improvements are: comprise vertical bucket elevator, sandbox, motor, case, main shaft, pouring sand cylinder and hopper; Described vertical bucket elevator is provided with screw feeder by feedstock transportation to vertical bucket elevator top; Described sandbox, pouring sand cylinder and hopper are fixedly connected on the same side of vertical bucket elevator from top to bottom; Described hopper is fixedly connected on the feed bin of vertical bucket elevator, communicates bottom it with the feed bin of vertical bucket elevator; Described sandbox is the casing of a upward opening, is placed in the below of vertical bucket elevator top discharge mouth; Described case is arranged between sandbox and hopper, is semi-closed structure, will drench sand cylinder and hopper and surround wherein, below it, towards the open-front of operating position; Described motor is fixedly connected on case top board, and its output shaft down runs through case top board and is connected with main shaft; The lower end of described main shaft is provided with the flat scraper of several strip, and described flat scraper is arranged at and drenches in sand cylinder; Discharging opening bottom described sandbox runs through case top board and is placed in the top drenching sand cylinder upper opening; Sieve sand net is provided with bottom described pouring sand cylinder.
Such scheme further improves and is, described sandbox internal upper part is provided with tilted-putted screen cloth; On sandbox sidewall, the lower position of corresponding screen cloth is provided with opening, and the below of opening is provided with dustbin.
Such scheme further improves and is, described flat scraper be 3 centered by the central axis of main shaft, circumferential equally distributed flat scraper.
Such scheme further improves and is, described case both sides are provided with the perpendicular sweep-up pipe put, and its upper end suction inlet is arranged on sandbox side wall upper part, and with sandbox inner space, its lower end suction inlet is arranged on the housing sidewall above hopper, with case inner space.
The present invention compared with prior art, has following good effect:
1, utilize the flat scraper rotated the sand flowed down from sandbox to be laid in equably the bottom drenching sand cylinder, effectively avoid sand grains to concentrate, make sand dispersed, significantly improve and drench sand uniformity.
2, the screen cloth of inclination is set in sandbox, large sand grains can be blocked, rubbish also can be discharged from the outlet of sandbox side, prevent large sand grains etc. from blocking sieve sand net, improve further and drench sand uniformity.
3, flat scraper be 3 centered by the central axis of main shaft, circumferential equally distributed flat scraper, like this, more uniformly the sand flowed down from sandbox can be laid in equably the bottom drenching sand cylinder.
4, hopper both sides are provided with sweep-up pipe, the grains of sand that Absorbable rod flies upward, and effectively improve efforts environment.
