Description
Technical field
The invention belongs to broken or pulverize being separated or sorting field of the material that matches, be specifically related to a kind of fodder crushing and separation equipment.
Background technology
Feed grinder is mainly used in pulverizing all feeds and various roughage, the object of fodder crushing increases feed surface sum adjustment granularity, increases surface area and improve palatability, and contact with digestive juice at digestion Bian Neiyi, be conducive to improving digestibility, better absorb feed nutrient.Adjustment granularity decreases on the one hand livestock and poultry and chews energy to consuming, and another aspect is to carrying, storing, mix and granulate more convenient, efficiency and better quality.
Feed grinder common at present, in the process pulverizing chicken feed, can produce a large amount of dust, and dust can disperse in atmosphere, so on the one hand contaminated environment, wastes resource on the other hand.Patent publication No. is that a kind of feed stuff reducing device of CN202516671U can prevent the feed of powdery from scattering in atmosphere, its structure comprises: pulverizer, strength discharge nozzle, strength suction tube, described strength discharge nozzle is tangentially connected to the top of feed cylinder, the middle part of feed cylinder is provided with strength feed back pipe, described strength feed back pipe is connected with feed cylinder tangentially, and being provided with below of the connection mouth of pipe of strength discharge nozzle and feed cylinder is separated inboard cylinder to feed and protrudes stock guide.Adopt above-mentioned pulverizer in the process pulverized, bulky grain feed is difficult to enter in strength discharge nozzle completely, and bulky grain chicken feed can mix with mash feed greatly; In addition, under the suction of strength discharge nozzle, the chicken feed of powdery can enter in strength discharge nozzle with oarse-grained chicken feed, inferior separating effect.
Summary of the invention
The object of the present invention is to provide a kind of fodder crushing and separation equipment, use this equipment to powdery and bulky grain feed good separating effect.
For achieving the above object, base case of the present invention is as follows:
Fodder crushing and separation equipment, comprise pulverizer, strength discharge nozzle and feed back pipe, also be provided with knockout tower, negative pressure staving, air-introduced machine and settling tank, described negative pressure staving is positioned at knockout tower, and negative pressure staving sidewall is offered the sorting hole that some diameters are less than bulky grain feed, described negative pressure staving and settling tank by pipeline communication, and described air-introduced machine are installed by this pipeline; Described strength discharge nozzle one end is communicated with the discharging opening of pulverizer, and the other end is communicated with knockout tower, and described feed back pipe one end is communicated with bottom knockout tower, and the other end is communicated with the charging aperture of pulverizer.
The principle of this programme: when specifically using, start pulverizer and air-introduced machine, feed to be broken is added in pulverizer, pulverizer carries out fragmentation to feed continuously, feed after fragmentation is through strength discharge nozzle and enter in knockout tower, air-introduced machine operationally, negative pressure is formed in negative pressure staving, owing to negative pressure staving sidewall being offered the sorting hole that some diameters are less than bulky grain feed, so the feed in powdery enters in negative pressure staving through sorting hole, the feed of large grained then falls to bottom knockout tower, and reenters in pulverizer through feed back pipe and again pulverize.
The advantage of this programme is: in this programme, negative pressure staving is provided with in knockout tower, when air-introduced machine runs, the negative pressure formed in negative pressure staving is by the mash feed negative suction staving in knockout tower, so just the feed of mash feed and large grained can be separated, mash feed enters sedimentation in settling tank through pipeline, thus prevents the feed of powdery from again entering in pulverizer.
Prioritization scheme 1, to the further optimization of base case, is also provided with dredging pipeline, and this dredging pipeline one end is communicated with fan out draft side, and the other end is communicated in negative pressure staving, and described dredging pipeline is provided with valve.In use procedure, sorting hole can block from the outside of sorting hole by feed, now opens the valve on dredging pipeline, and air blasts in negative pressure staving by dredging pipeline, and the air pressure in such negative pressure staving increases, thus is dredged by sorting hole.
Prioritization scheme 2, to the further optimization of base case, described negative pressure staving is up-small and down-big round table-like.When negative pressure staving is above-mentioned shape, the feed through the ejection of strength discharge nozzle can be attached to the outer surface of negative pressure staving, and the feed of such powdery is more easily by negative pressure negative suction staving, and separating effect is better.
Prioritization scheme 3, to the further optimization of base case, any one of prioritization scheme 1,2, in funnel-form bottom described negative pressure staving, and pipeline is connected with bottom negative pressure staving.The mash feed be inhaled in negative pressure staving can partly be deposited on bottom negative pressure staving, when arranging in a manner described, even be deposited on the mash feed bottom negative pressure staving, also can enter in settling tank through pipeline.
Prioritization scheme 4, to the further optimization of prioritization scheme 3, the outer surface of described negative pressure staving and knockout tower inwall is equipped with some tapers projection.Taper projection from the outer surface and knockout tower inwall of feed and the negative pressure staving of the ejection of strength discharge nozzle collide, so just can again by the fragmentation of bulky grain feed, the effect of raising fragmentation.
