Abstract
The utility model belongs to the technical field of screening equipment's technique and specifically relates to a sieving machine is related to, be equipped with the shale shaker between upper ledge and the lower frame, be equipped with vibratory screen in the lower frame, vibratory screen includes annular fixing base, screen cloth, annular fixed loop, the screen cloth is fixed in between fixing base and the fixed loop, block locking each other between fixing base and the fixed loop. The advantage is: saved a large amount of manpowers when guaranteeing the accuracy, improved work efficiency, solved present laboratory and do not had serialization coarsegrain screening method.
Description
Technical field
The utility model relates to the technical field of screening plant, especially relates to a kind of vibrating sieving machine.
Background technology
Granularmetric composition is a key character of coal, carry out the assortment of coal, Study on Coal washability, determine coal preparation method and equipment, the technological transformation etc. of black water link all will consider the granularity of coal, therefore granularity project becomes the important test item importing and exporting Coal trades.Mostly be coarsegrain screening owing to importing and exporting granularity project to be detected in coal Inspection and Supervision, the sample related to often reaches up to a hundred kilograms even weight of several tons.The existing mechanical screening device that detects for granularity project or as matching used granulometry device in large-scale marketable coal sampling apparatus because of invest high, volume large and be difficult to be applied in Routine Test Lab detects, or significantly reduces operating efficiency as large-scale vibrating sieving machine because realizing continuous operation.The artificial method for sieving that most laboratory adopts, not only will consume a large amount of manpowers, and with duration, is difficult to meet the testing requirement importing and exporting coal Inspection and Supervision precise and high efficiency.Probe into and be suitable for laboratory applications and the new detection method of the import and export coal granularity project of precise and high efficiency, solving that laboratory lacks can the coarsegrain method for sieving difficult problem of continuous operation, is the new problem that current import and export coal inspection and quarantine workers urgently study.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the purpose of this utility model be to provide a kind of ensure accuracy while save a large amount of manpower, improve operating efficiency, solve the difficult problem vibrating sieving machine of current laboratory without serialization coarsegrain method for sieving.
For realizing above-mentioned object, the utility model provides following technical scheme:
A kind of vibrating sieving machine, be provided with vibratory sieve between upper ledge and lower frame, be provided with vibration screen in lower frame, vibration screen comprises holder, screen cloth, the annular retainer ring of annular, screen cloth is fixed between holder and retainer ring, mutually engages locking between holder and retainer ring.
The utility model is set to further: between described holder and retainer ring, the concrete structure of engaging locking is mutually: the inner ring of holder is provided with the enclosure wall of annular, lower serrate projections is circumferentially provided with on the upside of enclosure wall, retainer ring is provided with the annular groove matched with enclosure wall, is provided with the upper serrate projections matched with lower serrate projections in groove.
The utility model is set to further: the external diameter of described retainer ring is equal with the external diameter of holder.
The utility model is set to further: described holder is circumferentially provided with several fixing holes, and described retainer ring is provided with the through hole corresponding with fixing hole position.
By adopting technique scheme, the technique effect that the utility model reaches is: while guarantee accuracy, save a large amount of manpower, the coal sample that can process 1000 kilograms per hour, conveniently go out coal sample in time, do not block, improve operating efficiency, facilitate pan feeding, also facilitate discharging to clear up, solve the difficult problem of current laboratory without serialization coarsegrain method for sieving, for conscientiously improving the scientific and efficient important in inhibiting that coal Inspection and Supervision work is imported and exported at port.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is side structure principle schematic of the present utility model.
Fig. 2 is the structural principle schematic diagram of vibration screen of the present utility model.
Detailed description of the invention
With reference to Fig. 1, 2, a kind of vibrating sieving machine disclosed in the utility model, vibratory sieve 12 is provided with between upper ledge 10 and lower frame 11, vibration screen 13 is provided with in lower frame 11, vibration screen 13 comprises the holder 14 of annular, screen cloth, the retainer ring 16 of annular, screen cloth is fixed between holder 14 and retainer ring 16, mutually locking is engaged between holder 14 and retainer ring 16, its concrete structure is: the inner ring of holder 14 is provided with the enclosure wall 17 of annular, lower serrate projections 18 is circumferentially provided with on the upside of enclosure wall 17, retainer ring 16 is provided with the annular groove matched with enclosure wall 17, the upper serrate projections 19 matched with lower serrate projections is provided with in groove.Wherein the external diameter of retainer ring 16 is equal with the external diameter of holder 14, holder 14 is circumferentially provided with several fixing holes 20, and retainer ring 16 is provided with the through hole 15 corresponding with fixing hole 20 position.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
