Abstract
The utility model discloses a sand grading and screening device which comprises a cylinder which is horizontally arranged on a frame, wherein a rotating shaft is arranged in the center of the cylinder; spiral blades are arranged on an outer wall of the rotating shaft; a feeding hole and a discharge opening are respectively formed in two ends of the cylinder; a sieve plate is obliquely arranged on the frame at the lower end of the cylinder; the lower end of the sieve plate is conical; a flange is arranged on the edge of the sieve plate; a vibrator is arranged on the lower end face of the sieve plate. The sand grading and screening device is novel in structural design, sand raw materials can be conveniently and rapidly treated through a spiral stirring and cleaning structure and a vibrating sieve plate, the grading standard is reached, the process is optimized, and the processing efficiency is improved.
Description
technical field:
The utility model relates to molding sand processing, relates in particular to a kind of molding sand classified screening device.
background technology:
Molding sand is mainly by natural silica Sand is carried out to washing, removes earth impurity and obtains product.At present, going deimpurity process is that roughing sand is added water and makes mortar, then carries out desliming through sending into desliming bucket to sandpipe, and processing procedure water utilization rate is relatively low, and treatment effeciency is low.
In certain above-mentioned processing procedure, can not, to the processing of molding sand product pulvis, therefore need multiple working procedure just can reach the grade of needs, increase hand labor intensity, improve cost.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of molding sand classified screening device, reasonable in design, cheap for manufacturing cost, can conveniently process molding sand raw material, reach the standard of classification, optimize operation, improved the efficiency of processing.
The technical solution of the utility model is as follows:
Molding sand classified screening device, it is characterized in that: comprise the cylindrical shell that level is rack-mounted, cylindrical shell center is provided with rotating shaft, rotating shaft outer wall is provided with helical blade, the two ends of cylindrical shell are respectively charging aperture and discharging opening, and the frame of described cylindrical shell lower end tilts sieve plate is installed, and the lower end of sieve plate is taper, the edge of sieve plate is provided with gear edge, and the lower surface of sieve plate is provided with vibrator.
Described molding sand classified screening device, is characterized in that: described cylindrical shell has upper half-shell, housing lower half assembling to form, and on housing lower half, is wherein the semicircular screen drum that is evenly distributed with through hole.
Described molding sand classified screening device, is characterized in that: the lower rear of the discharging opening of described cylindrical shell, the discharging opening of sieve plate, sieve plate is respectively equipped with one-level ash can, secondary ash can, case connects material.
The utility model has the advantages that:
The utility model structural design novelty, can conveniently process molding sand raw material by the sieve plate of screw type stirring and washing structure, vibrations, reaches the standard of classification, has optimized operation, has improved the efficiency of processing.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
detailed description of the invention:
Referring to accompanying drawing:
Molding sand classified screening device, comprise the rack-mounted cylindrical shell of level 1, cylindrical shell 1 center is provided with rotating shaft 2, rotating shaft 2 outer walls are provided with helical blade 3, the two ends of cylindrical shell 1 are respectively charging aperture 4 and discharging opening 5, and the frame of cylindrical shell 1 lower end tilts sieve plate 6 is installed, and the lower end of sieve plate 6 is taper, the edge of sieve plate 6 is provided with gear along 7, and the lower surface of sieve plate is provided with vibrator 8.
Cylindrical shell 1 has upper half-shell 1-1, housing lower half 1-2 to assemble formation, and wherein housing lower half 1-2 is upper for being evenly distributed with the semicircular screen drum of through hole.
The lower rear of the discharging opening of cylindrical shell 1, the discharging opening of sieve plate 6, sieve plate 6 is respectively equipped with one-level ash can 9, secondary ash can 10, case 11 connects material.
