Description
Technical field
The present invention relates to a kind of grinding screening plant of stalk powder, and in particular to straw is sieved in water circulation type wet grinding
The device of powder.
Background technology
Straw is the general name of ripe crops stem and leaf (fringe) part.It is often referred to Semen Tritici aestivi, Oryza sativa L., Semen Maydiss, potato class, Brassica campestris L, cotton
The remainder of flower, Caulis Sacchari sinensis and other crops (usually coarse grain) after seed is harvested.The photosynthetic product of crops has
More than half is present in straw, and straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter etc., be it is a kind of have it is multiduty can be again
Raw living resources, straw is also a kind of roughage.Feature is crude fiber content height (30%-40%), and containing lignin etc..
Thus, a kind of method that utilization straw prepares dietary fiber is disclosed in prior art, in the method, the particle diameter of straw is had
It is strict with.
In the prior art, the stalk particle in certain particle size range is prepared, needs are first crushed to it, Ran Hou
Sieved, operated very loaded down with trivial details；And in screening process, the stalk powder particle diameter needed for due to preparing cellulose is one
In individual less particle size range, if the equipment of screening is not that closed space or obturation effect be not good, airborne dust is easily caused non-
Chang Yanchong, so affect operator it is healthy.
The content of the invention
The technical problem to be solved is：In prior art, the equipment of screening is not closed space or closed
Effect on driving birds is not good, is easily caused the very serious situation of airborne dust and occurs, and then affects operator's healthy, the mesh of the present invention
Be that the device that stalk powder is sieved in water circulation type wet grinding is provided, solve the above problems.
The present invention is achieved through the following technical solutions：
The device of stalk powder is sieved in water circulation type wet grinding, including cavity, the charging aperture being arranged on cavity and is gone out
Material mouth, and the screen cloth being arranged in cavity, are provided with two sieving plate installing frames in the cavity, the screen cloth is arranged on should
Three chambers being sequentially arranged are separated on sieving plate installing frame and by cavity, three chambers being sequentially arranged are respectively just
Level processing chamber housing, finished product collection chamber and little particle reclaim chamber；
The charging aperture is located at the top of primary treatment chamber, and the discharging opening is located at the bottom of finished product collection chamber, institute
The bottom for stating primary treatment chamber arranges a big particle diameter outlet, and in the big particle diameter outlet ball mill, the ball milling are connected

The little particle to be reclaimed and be additionally provided with recovery port on chamber, and a sedimentation tank is connected with the recovery port, described heavy
Shallow lake pond is by water pump and primary treatment chamber；The bottom of the primary treatment chamber and finished product collection chamber is respectively provided with one
Agitating device.
Stalk powder particle diameter needed for due to preparing cellulose is less, when being sieved using conventional screening plant, not only
The size for being only easily caused screening is not accurate enough, and easily airborne dust, if operator work in such a case, holds
Easily unhealthful, the mode of shaking-sieving of the prior art is modified as water and drives screening by the present invention, and optimizes the present invention
Overall structure, by the optimization of present configuration, the situation that can be prevented effectively from airborne dust occurs, it is ensured that the person of operator is good for
Health.
The present invention can be sieved accurately by the screening mode in cavity using multistage filter screen in combination with waterpower drive
Go out the stalk particle of required particle diameter size, and avoid harm caused by airborne dust, effect is very notable.
Also, the setting that the present invention passes through agitating device, effectively by the straw in primary treatment chamber and finished product collection chamber
Stalk powder is more preferable with water body to mix homogeneously, and then under the drive of water body, is preferably sieved, and makes screening efficiency higher.
Meanwhile, the water body in the present invention can reduce cost input with cycling and reutilization.
By the stalk powder of the big particle diameter after water sieve point in the present invention, when a certain amount is stacked into, can be by beating
Valve opening door, transports it into and again returned in cavity after grinding in ball mill, and then the utilization of raw material is better achieved.
Further, the outlet of the water pump is connected at primary treatment chamber top position.
Further, the agitating device includes extending to centre rotational axis at chamber bottom position from chamber top,
It is fixed on centre rotational axis top and positioned at the motor of cavity top end, more than one stirring arranged around centre rotational axis
Bar, the scraping blade on the puddler of centrally disposed rotary shaft lowermost end.The auxiliary vertical with connecting rod is additionally provided with the connecting rod
Puddler.The scraping blade is made up of quality of rubber materials.
In the present invention, by the setting of said structure, will further the stalk particle of finished product collection chamber bottom be deposited in
It is uniform with water mixing, and then be easy to bring particle diameter into little particle recovery chamber by the flowing of water body less than the stalk particle of demand
In room, screening efficiency is improved.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention can be sieved accurately by the screening mode in cavity using multistage filter screen in combination with waterpower drive
The stalk particle of required particle diameter size is separated, and avoids harm caused by airborne dust, effect is very notable；
2nd, it is of the invention by the setting of agitating device, effectively by the powder of straw in primary treatment chamber and finished product collection chamber
End is more preferable with water body to mix homogeneously, and then under the drive of water body, is preferably sieved, and makes screening efficiency higher；
3rd, the water body in the present invention can reduce cost input with cycling and reutilization.
