Abstract
The utility model relates to a combined screen analyzer which is suitable for testing the fineness of a powder product, such as cement, etc. The utility model is characterized in that the middle part of an outer shell is fixed with a gear box in which a worm gear and a worm screw are arranged; both sides of the gear box are respectively provided with a screen analyzing chamber formed by an upper plate and a lower plate of the outer shell; a bottle-shaped screen is arranged in the screen analyzing chamber; the lower part of the outer shell is connected with an air outlet, a dust collector and a blower; the outer part of the bottle-shaped screen is provided with a sample funnel. Power is transferred to the bottle-shaped screen from a motor through the worm screw and the worm gear to lead the bottle-shaped screen to be rotated, a sample enters the bottle-shaped screen to be screened and analyzed under the wind action of negative pressure formed by the blower, and fine dust is collected in the dust collector. The utility model can screen and analyze a plurality of samples for once, and has the advantages of high efficiency, low cost, simple structure, and convenient operation.
Description
The utility model relates to a kind of screen analysis instrument that is used for the check of powder product fineness such as cement.
At present the utensil of check granular material fineness has hand sieve, water sieve, negative pressure sieve etc., and its shortcoming is once can only sample of screen analysis, repetitive operation, time-consuming, as manufacture of cement check, the fineness that per hour will sieve 4 samples at least, tens samples of many persons, it is many to repeat link, is difficult to standard.Used round bottom standard sieve when processing and fabricating, mostly is manual processing, and is difficult for realizing Mechanized Processing; Work in-process, remaining leftover pieces are many, the waste screen material.
But the purpose of this utility model provides a plurality of samples of a kind of once screen analysis, efficient height, combination screen analyzer that cost is low.
The purpose of this utility model is achieved in that a kind of combination screen analyzer, and the shell center fixed has gear case, and worm gear, worm screw are installed in the gear case, and worm screw one end connects with motor shaft, and it is indoor that the two end axles of worm gear is stretched out the outer screen analysis of gear case; The screen analysis chamber is the space of the gear case both sides that formed by the loam cake of shell and base plate, and the bottom of shell is an infundibulate, and the centre is an air outlet, and air outlet is connected with dust-precipitator, and dust-precipitator one side is connected with blower fan; The indoor doleiform sieve that is equipped with of screen analysis, the square spindle nose of the bottom groove of doleiform sieve and worm-wheel shaft is pegged graft the hole wall rubbing contact of doleiform sieve shoulder and shell; The sample funnel also is installed outside the doleiform sieve, and sample funnel top is articulated on the shell by hinge, and the bottom is connected with hook and is mounted on outer casing bottom, and spout of funnel is inserted in the mouth of doleiform sieve.
The purpose of this utility model can also following manner realize:
Be connected with air inlet in bottom surface, screen analysis chamber, the wind of air inlet chews that to make progress into narrow slit parallel with sieve and press close to screen cloth, outer indoor narrow.
The doleiform sieve is made up of doleiform screen frame (unit) and screen cloth.
Described combination screen analyzer parallel connection is organized more, adopts a worm drive.
Described combination screen analyzer parallel connection has 3 groups, and a worm screw drives 3 worm gears, and both sides have 6 doleiform sieves.
The utlity model has following advantage: 1) screen analysis efficient height.Compare with common hand sieve, 2～10 samples of screen analysis simultaneously, in addition more.2) cost is low.Adopt the doleiform screen construction, not surplus leftover pieces, economical with materials, and be easy to realize mechanization production, reduce cost.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 structural representation of the present utility model
The structural representation of Fig. 2 doleiform sieve
The utility model can adopt one or more groups parallel connection unitized construction, when organizing, uses a motor more, connects a worm screw, drives a plurality of worm gear work.Every group has two doleiform sieves, apportion worm gear both sides.
The structure of every group of screen analyzer is: shell 1 center fixed has gear case 2, worm gear 3 and worm screw 4 are installed in the gear case 2, worm screw 4 connects motors, and it is indoor that the two end axles of worm gear 3 is stretched out the outer screen analysis of gear case, and the screen analysis chamber is the space of the gear case both sides that formed by the loam cake of shell 1 and base plate.The bottom of shell 1 is an infundibulate, and the centre is an air outlet 5, and air outlet 5 is connected with dust-precipitator (6); Dust-precipitator 6 one sides are connected with blower fan 7.At the indoor doleiform sieve 9 that is equipped with of the screen analysis of gear case both sides, the square spindle nose of the bottom groove of doleiform sieve 9 and worm-wheel shaft is pegged graft the hole wall rubbing contact of doleiform sieve 9 shoulders and shell 1.Sample funnel 11 also is installed outside doleiform sieve 9, and sample funnel 11 tops are articulated on the shell 1 by hinge 12, and the bottom is connected with hook 10 and is mounted on shell 1 bottom margin.Spout of funnel is inserted in the mouth of sieve 9.As required, can also be connected with air inlet 8 in bottom surface, screen analysis chamber.The wind of air inlet 8 chews that to make progress into narrow slit parallel with sieve and press close to screen cloth, wide outside and narrow inside.
The structure of doleiform sieve 9 is, doleiform screen frame (unit) 9-1 connects the bottle end and shoulder by the middle part dowel, and there is a square groove that is complementary with the square spindle nose of worm-wheel shaft in bottle end central authorities, and there is bottleneck in shoulder central authorities, and screen cloth 9-2 is fixed on the dowel at middle part.
The combination screen analyzer can be made into one or more groups parallel combination type according to user's needs, uses a motor to connect a worm screw and realizes.
The course of work: driven by motor worm screw, worm screw drive a plurality of worm gear rotations, and the worm gear drives sieve slowly rotates, and screen analysis material sample enters sieve by sample funnel 11, and under the blower fan suction, the micronic dust in the sample sees through sieve aperture and enters dust-precipitator by air outlet.Be provided with under the situation of air inlet, a part of wind enters from air inlet, blows the sieve original pattern product that boil, and can reach the purpose of cleaning screen cloth, and the screen analysis effect can be better.
