Description
Technical field
The present invention relates to the separation equipment of solid material in chemical process, particularly relate to a kind of multistage sieve with blower material equipment separated suitable in multiple particle diameter raw material.
Background technology
The solid product of Chemical Manufacture includes multiple particle diameter, product for different-grain diameter is generally adopted two kinds of operating procedures, a kind of is pulverized by the granule of wherein big particle diameter, and the material of all particle diameters is all ground into short grained material, carries out unifying to collect and discharging；Another kind is the product screen cloth of different-grain diameter to be carried out screening come, and is collected respectively by the product of different-grain diameter, with suitable in different supply of material demands.
Category filter for different-grain diameter material works, it is generally required to adopt multilevel screen that it is screened, but Normal practice on the market is to need material is repeatedly screened, the screen cloth selecting different-grain diameter respectively carries out sieve material operation, and then collect the product of different-grain diameter, complex operation, wastes time and energy；Also have some to also have the sieve material equipment of multilayer screen cloth on the market simultaneously, although these equipment can complete by disposable sieve material, but the operation of its feeding needs dismantle respectively and take off mesh structure, operate also inconvenient, simultaneously in sieve material process, the easy blocking screen web frame of oarse-grained material, causes short grained material not pass through, sieve material efficiency is low, it is necessary to coordinate the structure of other mechanical vibration just can complete sieve material operation.
Summary of the invention
For above-mentioned Problems existing, present invention aim at providing a kind of sieve material and rewinding convenient, sieve material efficiency is high, meets multiple particle diameter material and carries out screening and collecting the multistage sieve with blower material equipment of operation simultaneously.
nullIn order to achieve the above object，The technical solution used in the present invention is as follows: a kind of multistage sieve with blower material equipment，Described sieve material equipment is the housing sealed，Housing bottom is provided with air blast blower fan and air inlet，Case top is provided with air outlet，The middle part of described housing is sieve with blower feed bin，Described sieve with blower feed bin is flared structure，The end face radius of sieve with blower feed bin is more than its bottom surface radius，The differing heights of described sieve with blower feed bin is provided with multiple annular discharge nozzle，It is connected by filtrate screen cloth between discharge nozzle with sieve with blower feed bin，The outside of described discharge nozzle connects material transfer tube，The material transferring pipe respectively top transfer tube that described discharge nozzle connects from top to bottom、Secondary transmission pipe and lower transport pipe，Described top transfer tube is connected on fines collecting tank，Described fines collecting tank、Secondary transmission pipe and lower transport pipe are both connected on return duct，Described return duct is connected to the bottom of sieve with blower feed bin by reflux drum air pump.
Hull outside of the present invention is provided with vertical location bar, described material transferring pipe is installed in parallel on the bar of location, by the material transferring pipe that level is installed, the transport in material transferring pipe of the convenient material collected by air-flow, keep material transferring pipe stability in material transferring process.
Being equipped with rewinding screen cloth in secondary transmission pipe of the present invention and lower transport pipe, between described rewinding screen cloth and discharge nozzle, material transferring pipe is provided with discharging opening, and the underside of described discharging opening is connected to rewinding storehouse；Collecting, with lower transport pipe, the material comparing greater particle size by secondary transmission pipe, material under the effect of rewinding screen cloth, in the rewinding storehouse of its correspondence that drops respectively, is automatically performed its rewinding work in secondary transmission pipe under the effect of air-flow and screen cloth.
Rewinding storehouse of the present invention includes secondary rewinding storehouse and coarse fodder rewinding storehouse, and described rewinding storehouse is fixed by snap on the securing lever；Location bar can be not only used for the location of material transferring pipe, it is also possible to is used for fixing rewinding storehouse, facilitates the rewinding storehouse that rewinding is completed by operator to take off, simple to operation.
In the present invention, the aperture of filtrate screen cloth and its setting height(from bottom) are inverse ratio, owing to material is under airflow function, the floating of material particle diameter highly with itself is inversely proportional to, and therefore collects small particles material by the filtrate screen cloth on sieve with blower feed bin top, collects large granular materials by the filtrate screen cloth of its underpart.
In the present invention, the aperture of rewinding screen cloth and its setting height(from bottom) are inverse ratio, owing to the material transferring pipe below sieve with blower feed bin itself can draw the short grained material of part, therefore at material in the process that lower transport pipe transmits, by rewinding screen cloth oarse-grained material retained and collect, by short grained material by airflow reflux to sieve with blower feed bin.
On sieve with blower feed bin of the present invention, the quantity of secondary transfer tube is no less than one；The top transfer tube of sieve with blower feed bin is used for collecting small particles material, lower transport pipe is used for collecting oarse-grained material, secondary transmission pipe is for collecting the material of particle diameter between the two, operator according to the collection demand of different-grain diameter material, can arrange many group secondary transmission pipes and discharge nozzle on sieve with blower feed bin.
In the present invention, the mesh size of the filtrate screen cloth of single height is more than the mesh size of its mutually level rewinding screen cloth, the mesh size of the filtrate screen cloth of single height is identical with the mesh size of the rewinding screen cloth of adjacent height below, owing to the main purpose of filtrate screen cloth is to collect the material of regulation particle diameter, and the effect of rewinding screen cloth is the material retaining this section of particle diameter, facilitating passing through of little particle diameter material, therefore both mesh sizes are tilt correspondence on device.
Material transferring pipe of the present invention is provided with flow control valve, controls the air-negative-pressure in differing heights material transferring pipe by flow control valve, meets the collection demand of variety classes material.
Being provided with storing platform between air blast blower fan of the present invention and sieve with blower feed bin, described return duct is connected to the top of storing platform, and the Main Function of return duct is for air-flow and feed back, conveniently the material of backflow is re-started screening operation.
It is an advantage of the current invention that: traditional multistage sieve material equipment is improved by the present invention, the mask work of different-grain diameter material is completed by the dual function of air-flow and gravity, device is by the combination of material transferring pipe and rewinding storehouse, at the automatic collection work simultaneously completing logistics separated；For device at the small particles material separated and be strayed in collection process, the mode refluxed by pipeline imports in sieve with blower feed bin again, and apparatus structure is simple, and operating automation degree is high；Meet enterprise's collection to multiple different-grain diameter material to operate, solve in prior art Problems existing, good practical effect in multistage material screen material equipment.
