Abstract
The utility model discloses a linear vibrating screen, which comprise a base frame, a screen body and a high-frequency vibrator, wherein the high-frequency vibrator is arranged under the screen body which is arranged on the base frame; a vibration absorber is arranged between the screen body and the base frame; and the screen body is provided with a liquid inlet, a filter screen, a liquid outlet and a slag outlet and is obliquely arranged downward from the liquid inlet to the liquid outlet relative to a horizontal plane. The linear vibrating screen is characterized by further comprising a liquid distributor which is arranged under the liquid inlet and is arranged above the filter screen at a digging angle with the filter screen. The utility model has the advantages of favorable screening defect, strong slag discharge capability and the like.
Description
Technical field
The utility model relates to a kind of sieving machine, is specifically related to a kind of linear vibrating screen that is used for the tobacco sheets by paper making method extract.
Background technology
Tobacco sheets by paper making method is that utilization tobacco leaf reconstruction technique is handled by the papermaking principle offal in the tobacco production process, offal and part tobacco leaf through processing, makes the thin slice near natural tobacco leaf, is used further to a kind of advanced person's of production of cigarettes tobacco production technology.The reconstituted tobacoo that the paper process thin slice is compared other explained hereafter more helps the reducing cigarette tar and reducing harm reduction and improves the cigarette interior quality.During tobacco sheets by paper making method was produced at home at present, the cleanliness factor that how to improve the tobacco extract was one of technical work of a key.Extract is that water extracts tobacco after the resulting a kind of liquid of Separation of Solid and Liquid, it contains a large amount of solubility tobacco components, simultaneously in the Separation of Solid and Liquid process, also bring more insoluble impurities, as mud, sand, tiny cigarette ash and offal etc.The too high meeting of these impurity contents has influence on production efficiency, easily causes the evaporimeter internal incrustation as the high tobacco extract of impurity content when the evaporation and concentration, influences evaporation efficiency; And for example the impurity in the extract takes in the concentrate, can influence the production continuity, influences the effective yield etc. that manufactures a finished product.So, in the tobacco sheets by paper making method manufacture process, must remove the insoluble impurities in the extract, improve the cleanliness factor of extract.
The existing means that adopt mainly contain following two kinds on the solution that purifies tobacco extract: first kind is that high speed centrifugation filters, this is a kind of gravity centrifugal process, can only remove the density mud bigger, sand material than liquid, and it is relatively poor to lighter offal, cigarette ash treatment effect, simultaneously this method requires the feed liquor dregginess not surpass 10%, and price is uneconomical, is higher than to shake sieve more than 10 times; Second kind is that drum-type and cylinder filter, and this filter finds that its deslagging ability is poor after how tame thin slice producer uses, and mesh often stops up, and causes screening effect very poor.
Summary of the invention
Technical problem to be solved in the utility model is that existing vibratory sieve is improved, and the straight line high-frequency that a kind of screening effect is good, deslagging ability is strong vibratory sieve is provided, to overcome the above-mentioned defective that prior art exists.
The technical scheme of the utility model technical solution problem is as follows:
A kind of linear vibrating screen, comprise underframe, sieve nest and dither, described dither is arranged on the sieve nest below, and described sieve nest is arranged on the underframe, is provided with dashpot between sieve nest and the underframe, described sieve nest is provided with inlet, screen pack, liquid outlet and slag notch, the relative horizontal plane of sieve nest, be is characterized in that to the downward-sloping setting of liquid outlet by inlet, also comprises liquid distributor, described liquid distributor is arranged on the inlet below, is an entrance angle with screen pack and is arranged on the screen pack top.
The utility model improves by the distributing mode to existing powder vibratory sieve, makes it become the liquid vibration sieve.By the distance of the liquid outlet of liquid distributor and screen pack and incision angle etc. have all been done improvement, reduced when liquid is come in the impact of mesh, guaranteed that liquid progressively separates with impurity, thereby improved separating effect.When tobacco extract is pumped to inlet, when being evenly distributed to straight net by liquid distributor, clean liquid leaked straight net to be dropped in the cell body, flows to liquid outlet; The impurity of being told by straight mesh screen is assembled on the net and is agglomeratingly moved to the slag notch direction then under the vibration of two high-frequency vibrators, finishes the journey of haveing suffered of filtration.
The beneficial effects of the utility model are: deslagging is effective, can improve the extract cleanliness factor by the order number that increases straight net mesh, has shortened the fouling of evaporator cycle on the one hand, saves the evaporimeter cleaning charge and uses; On the other hand, can reduce the discharge capacity of coating waste liquid, improve the effective yield of product, save the supplementary product onsumption expense; Can also enlarge the scope of application of raw material at last, can expand the scope of using below 60～80 orders to, play the purpose that economizes in raw materials by the offal raw material more than original 40 orders.
Description of drawings
Fig. 1 is the utility model linear vibrating screen principles of construction figure.
Fig. 2 is the utility model plan structure figure.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, 2, the utility model linear vibrating screen, comprise underframe 1, sieve nest 2 and dither 3, described dither 3 is arranged on sieve nest 2 belows, described sieve nest 2 is arranged on the underframe 1, be provided with dashpot 4 between sieve nest 2 and the underframe 1, described sieve nest 2 is provided with inlet 5, screen pack 6, liquid outlet 7 and slag notch 8, sieve nest 2 relative horizontal planes by inlet 5 to liquid outlet 7 downward-sloping settings, also comprise liquid distributor 9, described liquid distributor 9 is arranged on inlet 5 belows, is an entrance angle with screen pack 6 and is arranged on screen pack 6 tops.
Further, the fluid height of described liquid distributor 9 is between 20mm～50mm, and preferred distance is 30mm.Thereby can reduce the impact of liquid, guarantee residue-discharge convenience, improve filter effect screen pack.
Described liquid distributor 9 is the winnowing pan shape, and the width of its A/F and screen pack 6 adapts.The entrance angle of described liquid distributor 9 and screen pack 6 is between 1 °～5 °, and preferred entrance angle β is 3 °.By adopting liquid distributor that extract can be evenly distributed on the screen pack 6.
The gradient α of described sieve nest 2 is between 5 °～15 °, and the gradient of described screen pack 6 is identical with the gradient of sieve nest 2.
The bottom surface, lower end of sieve nest 2 nearly liquid outlet 7 one ends is funnel-form to lower convexity, and described liquid outlet 7 is arranged on bell mouth place, can be convenient to liquid and collect.
Described sieve nest 2 is the rectangle cell body.
The utility model operation principle: pending tobacco extract is pumped to inlet 5, extract via with screen pack 6 be that 3 ° liquid distributor 9 is evenly distributed on the screen pack 6 apart from 30mm, entrance angle β, under the double vibrations of dither 3, liquid is dropped into by screen pack 6 in the rectangle cell body of sieve nest 2 and is flow to liquid collection tank through liquid outlet 7, the impurity that filters out is then under the vibration of two high-frequency vibrators 3, be to assemble on 8 ° the screen pack 6 agglomeratingly to move at gradient α, thereby finish the journey of haveing suffered of filtration to slag notch 8 directions.
