Abstract
The utility model relates to ultrafine powder production equipment, in particular to a negative-pressure ultrafine powder vibration sieve. The negative-pressure ultrafine powder vibration sieve comprises a finished product bin, and is characterized in that one side of the upper end face of the finished product bin is provided with a filter shell integrated with the finished product bin; a negative pressure generator is arranged above a filter shell; a precise filter is arranged in the filter shell, and is connected below the negative pressure generator in a threaded manner. The negative pressure generator is arranged on one side of the finished product bin of the ultrafine powder vibration sieve, and the entire sieving process is performed under negative pressure, so that certain absorption force is generated for powder particles, the sieve is prevented from being blocked, particles of proper sizes can pass through the sieve, and the sieving efficiency is increased. Meanwhile, under the action of the negative pressure, dust is prevented.
Description
Technical field
The utility model relates to superfine powder production equipment, particularly a kind of negative pressure superfine powder vibratory sieve.
Background technology
Last procedure of superfine powder production process will sieve, and removes abnormal grain.Most of ultrasonic vibration sieve that adopts at present, the superfine powder particle sieving by ultrasonic vibration is through vibration and enter finished product bin under the effect of its gravity.This mode has two obvious defects: be first that powder granule is to pass through vibratory sieve by the effect of ultrasonic vibration and its gravity, there is no the effect of external force, easily cause screen cloth to stop up, reduce screening efficiency; Secondly in vibration processes repeatedly, produce dust, contaminated environment.
Summary of the invention
Problem to be solved in the utility model is: adopt negative pressure vibrosieve mode, prevent that screen cloth from stopping up, reduce dust and produce.
The technical solution of the utility model is a kind of negative pressure superfine powder vibratory sieve, comprise finished product bin, it is characterized in that: the side in finished product bin upper surface is provided with the filter housing being integrated with it, negative pressure generator is arranged on the top of filter housing, accurate filter is arranged in filter housing, is screwed onto the below of negative pressure generator.
The beneficial effects of the utility model are: because a side of the finished product bin at superfine powder vibratory sieve arranges negative pressure generator, whole screening process carries out under negative pressure state, powder granule has been produced to certain attraction, screen cloth is not easy to stop up, as long as the suitable screen cloth that just can pass through of granular size, improve screening efficiency, simultaneously because the effect of negative pressure has also prevented dust generation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As Fig. 1, negative pressure superfine powder vibratory sieve, comprise that material drops into feed bin 3, charger 4, the vibrating screen classifier 5 with screen cloth 5-1 and hairbrush 5-2, finished product bin 6, coarse grain collecting bag 7, be provided with the filter housing 6-1 being integrated with it in a side of finished product bin 6 upper surfaces, negative pressure generator 1 is arranged on the top of filter housing 6-1, accurate filter 2 is arranged in filter housing 3, is screwed onto the below of negative pressure generator 1.
When work; the material of needs screening is dropped in feed bin 3; by charger 4, material dosing is added to vibrating screen classifier 5, negative pressure generator 1 produces negative pressure; superfine powder is under the effect of negative-pressure air power and gravity; enter finished product bin 6 by screen cloth 5-1, abnormal grain flows into coarse grain collecting bag 7 in the effect of hairbrush 5-2, for preventing that superfine powder from entering negative pressure generator 1; accurate filter 2. is installed in the time shutting down on the top of finished product bin 6, the superfine powder on accurate filter 2 falls into finished product bin 6 automatically.
Claims (1)
1. a negative pressure superfine powder vibratory sieve, comprise finished product bin (6), it is characterized in that: be provided with the filter housing (6-1) being integrated with it in a side of finished product bin (6) upper surface, negative pressure generator (1) is arranged on the top of filter housing (3), accurate filter (2) is arranged in filter housing (6-1), is screwed onto the below of negative pressure generator (1).
