Abstract
The utility model discloses a screw feeding device of a closed cycle drying system. The device comprises a shell and a motor retarding mechanism, wherein the shell is internally provided with a spindle driven by the motor retarding mechanism; the top surface of the front end of the shell is provided with a charging hopper; the bottom surface of the rear end of the shell is provided with a discharge hole; the front section of the spindle is a screw section, and the rear section thereof is provided with a crushing blade to be the crushing section; the top of the shell, corresponding to the junction of the screw section and the crushing section of the spindle, is raised upwards to form a protrusion part, thus forming a material seal space in the shell. In the using process of the screw feeding device, plugging is formed through the natural accumulation of the materials in the material seal space formed by protruding upwards the shell, thus preventing the nitrogen from leaking and keeping the pressure in the system stable, and the material seal type screw feeding device has simple structure, and is convenient in use and hard to damage.
Description
Technical field
Relate to a kind of screw feeding device at the utility model, suit especially in the closed cycle drying system, to use.
Background technology
In continuous drying production, need continuous charging; conventional feeding device is the feeding device of single screw rod or twin-screw; promotion extruding by screw rod; material is pushed into hothouse; can realize automatic continuous charging; then with regard to the commute oxidation of nitrogen protection; low melting point; thermal sensitivity and contain organic solvent material and carry out dry closed cycle drying system; in dry run; need isolated nitrogen to leak; intercepting outside air enters in the system; maintenance system internal gas pressure balance; oxygen residual quantity in the strict control system; guarantee production safety, for this reason, conventional feeding device is to be unsuitable for the commute oxidation; low melting point; thermal sensitivity and contain organic solvent material and carry out using in the dry closed cycle drying system.
Summary of the invention
Be to propose a kind of closed circulation systemization that is suitable for easy oxidation, low melting point, thermal sensitivity and contains organic solvent wet stock drying in the purpose of this utility model
For achieving the above object, the utility model is taked following technical scheme:
The utlity model has housing, motor decelerating mechanism, be provided with the main shaft that drives by motor decelerating mechanism in the housing, the front end end face of housing is provided with loading hopper, bottom surface, housing rear end is provided with discharging opening, the leading portion of described main shaft is a spiro rod section, it is reduction stage that the back segment of main shaft is provided with broken blade, the intersection of the top of housing and the spiro rod section of corresponding main shaft and the reduction stage formation protuberance that raises up, thus in housing, form material envelope space.
Be provided with guard grating and anti-bridge formation device in the described loading hopper.
The intersection opening of the top of described housing and the spiro rod section of corresponding main shaft and reduction stage, opening part is equipped with cover, thereby forms protuberance.
The utlity model has following good effect: 1, this material envelope type screw feeder in use, utilize material to be deposited in naturally that housing raises up and in form one material envelope space, form shutoff, obstruct nitrogen leaks, stablizing of maintenance system internal pressure, this material envelope type screw feeder is simple in structure, easy to use, not fragile.2, the main shaft of this material envelope type screw feeder is made up of spiro rod section and reduction stage.Because wet stock in reinforced process, through the promotion extruding of screw rod, can be squeezed into the cake bulk of distinct program,, do not influence the drying effect of material so being provided with of broken blade is in addition broken or pulverize to the cake lump material.And the material in the material envelope space flows to discharging opening when being broken with the rotation along with broken blade in an orderly manner.3, be provided with guard grating and anti-bridge formation device in the loading hopper of this material envelope type screw feeder, the setting of guard grating prevents that big thing from entering loading hopper and preventing from out to hinder the hand accident.And the pushing that can eliminate loading hopper internal cause wet stock that is provided with of anti-bridge formation device forms false crane span structure or the false phenomenon of reuniting and luming, and plays the effect that material enters feeder that promotes.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the present embodiment diagrammatic sketch;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Shown in the accompanying drawing, present embodiment has housing 1, motor decelerating mechanism 3, be provided with in the housing by motor decelerating mechanism 3 and drive main shaft 2, an end end face of nearly motor decelerating mechanism is provided with loading hopper 4 on the housing 1, be provided with guard grating 7 and anti-bridge formation device 8 in the loading hopper 4, housing other end bottom surface is provided with discharging opening 6.The setting of guard grating 7 prevents that big thing from entering loading hopper, prevents that operating personnel are careless the finger insertion.And the pushing that can eliminate loading hopper 4 internal cause wet stocks that is provided with of anti-bridge formation device 8 forms false crane span structure or the false phenomenon of reuniting and luming, and plays the effect that material enters feeder that promotes.The axle of anti-bridge formation device 8 passes through chain transmission 9 driven rotary by described motor decelerating mechanism 3.The leading portion of main shaft is spiro rod section 2-1, and it is reduction stage 2-2 that the back segment of main shaft is provided with broken blade 2-2-1, and the spiro rod section 2-1 here should be the major part that accounts for main shaft.The setting of broken blade be since wet stock in reinforced process, the promotion extruding through screw rod can be squeezed into the filter cake bulk of distinct program, so need in addition broken or pulverize, otherwise can directly influence the drying effect of material.The spiro rod section 2-1 of the top of housing 1 and corresponding main shaft 2 and the intersection of reduction stage 2-2 are provided with opening, opening part is equipped with cover 5, form protuberance, thereby in housing, form material envelope space k, in use, utilize material to be deposited in naturally in the material envelope space k, stop because of nitrogen and leak or extraneous air enters system and influences intrasystem pressure stability.When the material in the material envelope space k is broken with the rotation along with broken blade, flow to discharging opening 6 in an orderly manner, through the discharging opening blanking.
Claims (3)
