Description
The present invention relates to a kind of equipment of extruding flowable substance, this equipment is made up of two hydrostatic columns, be provided with through hole around one in two containers and can on the outer wall of a cylindrical inner, rotate, the material that is extruded infeeds internal container vertically, and drop on the conveyer belt or salband that is positioned at its underpart sclerosis or condensation thereon by a row Kong Houcheng graininess.When two hydrostatic columns relatively rotate above-mentioned this row hole periodically with external container on through hole coincide.This row hole is positioned on the straight nozzle plate, and nozzle plate can be contained on the inner pressurd vessel circumference one and be parallel in the groove of hydrostatic column rotation, and nozzle plate supports on the inwall of container externally with its outside that is positioned at the channel opening limit.
Proposed the granulating equipment of some rotary make-up machines, the rotary make-up machine (EP-PS12192) that these equipment can not be changed existing nozzle plate has been done improvement.Nozzle plate can be changed and make rotary former be applicable to various application target under the situation that increases manufacturing cost exceeding.
Nozzle plate must adopt the material of good sliding properties, because especially in extruding during low-viscosity substances, nozzle plate is being close on the inwall of rotary container under the effect of material pressure.Generally be to use grey cast-iron.The shortcoming that adopts this material is for for example not having corrosive medium with this version granulating, because grey cast-iron can be corroded.Another shortcoming is that nozzle plate can be worn.
Task of the present invention is to make a kind of rotary particle forming machine of the sort of type of being mentioned at the beginning at this paper, and it is to carrying out granular material without limits.Be provided with outstanding sealing device in the outside of nozzle plate in the equipment of the present invention, the sealing device is close on the inwall of external container.Such version no longer is bearing on the external container of rotation the used material of nozzle plate itself, the just sealing device of being close to it, and the material of sealing device can be selected as requested.Nozzle plate itself for example can be made by the high-quality steel of the erosion medium resistance that can not be corroded in the present embodiment.Therefore enlarged the scope of application of rotary particle forming machine.
The form of making sealing strip by elastomeric material constitutes that the way of sealing device is relatively good, and under the effect of pressure, it is pressed in the inner surface of the external container that is rotating firmly, and its inner surface that do not wear and tear.Use after a period of time, if sealing strip heavy wear can be changed.
Nozzle plate is placed in the groove with two parallel side walls, and to make it to press to inwall under the effect of compression spring be very favourable.When very little or rotary particle forming machine stopped when the squeeze pressure of wanting granular material, compression spring still guaranteed with certain pressure nozzle plate to be pressed on the external container.These compression springs can be enclosed within on the feed part of tubulose, the feed part makes and is used for infeeding the axial chamber of wanting pressurizing medium in the internal container is communicated with an axial balanced chamber adjacent with nozzle plate under pressure, balanced chamber can be made of a pipe with square-section, be provided with the hole at it towards that side of nozzle plate, these holes are corresponding with the hole on the nozzle plate.This structure has guaranteed that the material that will push can enter rectangular tube by the feed part, and arrives nozzle plate from rectangular tube, and can not enter keep nozzle plate itself can radially movable zone in.Spring force has replaced extruding force in such an embodiment, and remains same size, and pressure big or small have nothing to do required with extruded material.This point is for low viscous material advantageous particularly, because the extruding force that needs in this case is smaller.
Below accompanying drawing be two embodiment of the present invention, and the present invention is further illustrated whereby.
