Abstract
The utility model relates to a double-screw extruder with a filter screen at a feed port, which can prevent a ribbon in a raw material bag from falling into a storage bin, and belongs to the technical field of chemical machinery. The double-screw extruder with the filter screen at the feed port is characterized in that the double-screw extruder comprises a double-screw extruder body (1), wherein a feed barrel (2) is arranged on the double-screw extruder body (1), a mixing hopper (3) is connected to the upper part of the feed barrel (2), a loss-in-weight scale (4) is arranged above the mixing hopper (3), a feed bin (5) is connected to the loss-in-weight scale (4), a feed port (6) is formed at the top of the feed bin (5), and a filter screen (7) is fixed in the feed port (6). According to the double-screw extruder with the filter screen at the feed port, the additional arrangement of the filter screen in the feed port can prevent the ribbon in the raw material bag from falling into the storage bin, so as to ensure the quality of raw materials.
Description
Technical field
The utility model relates to a kind of double screw extruder of spout band screen pack, can prevent that the silk ribbon in the former pocket from falling into storage bin, belongs to the chemical mechanical equipment technical field.
Background technology
Double screw extruder is in the spout at storage bin top, to pour raw material in the first step of producing, yet former pocket is a woven bag, and it is inner to produce friction with raw material contact back, can the silk ribbon that former pocket is inner grind to such an extent that come off and sneaks in the former pocket.When in spout, pouring raw material into, the silk ribbon in the former pocket just can fall into storage bin with raw material together, thereby extruding of raw material produced influence.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of can prevent that silk ribbon from falling into storage bin, guarantees the double screw extruder of the spout band screen pack of raw materials quality.
The purpose of the utility model is achieved in that
The double screw extruder of the utility model spout band screen pack; Comprise the double screw extruder body, the double screw extruder body is provided with barrel, and the top of barrel is connected with the batch mixing bucket; Said batch mixing bucket top is provided with weightless scale; Be connected with feeding bin on the said weightless scale, said feeding bin top has spout, is fixed with screen pack in the said spout.
Compared with prior art, the beneficial effect of the utility model is:
The double screw extruder of this spout band screen pack has added screen pack in spout, can the silk ribbon in the former pocket be blocked and do not fall into storage bin, thereby guarantee raw materials quality.
Description of drawings
Fig. 1 is the structural representation of the double screw extruder of the utility model spout band screen pack.
Fig. 2 is the vertical view of storage bin top spout in the double screw extruder of the utility model spout band screen pack.
Wherein: double screw extruder body 1, barrel 2, batch mixing bucket 3, weightless scale 4, feeding bin 5, spout 6, screen pack 7.
The specific embodiment
Referring to Fig. 1 and Tu, the utility model relates to a kind of double screw extruder of spout band screen pack, comprises double screw extruder body 1; Double screw extruder body 1 is provided with barrel 2; The top of barrel 2 is connected with batch mixing bucket 3, and said batch mixing bucket 3 tops are provided with weightless scale 4, is connected with feeding bin 5 on the said weightless scale 4; Said feeding bin 5 tops have spout 6, are fixed with screen pack 7 in the said spout 6.
When in spout 6, pouring raw material into, the silk ribbon in the former pocket just can be blocked on the screen pack 7, says that silk ribbon takes out, and just can guarantee the quality of raw material after adding raw material.
Claims (1)
