Abstract
The invention relates to a double-screw extruder with a filter screen at a feeding port, belonging to the technical field of chemical mechanical equipment and being capable of preventing silk ribbons in a raw material bag from falling into a storage bin. The double-screw extruder with the filter screen at the feeding port is characterized by comprising a double-screw extruder body (1), a charging barrel (2) is arranged on the double-screw extruder body (1), the upper part of the charging barrel (2) is connected with a blending bucket (3) above which a weightless balance (4) is arranged, a feeding bin (5) is connected to the weightless balance (4), and the top of the feeding bin (5) is provided with a feeding port (6) in which a filter screen (7) is fixedly arranged. Because the filter screen is additionally arranged in the feeding port, the double-screw extruder with the filter screen at the feeding port can prevent the silk ribbons in the raw material bag from falling into the storage bin, and then the qualities of raw materials are ensured.
Description
Technical field
The present invention 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, belong 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 invention provides and a kind ofly can prevent that silk ribbon from falling into storage bin, guarantee the double screw extruder of the spout band screen pack of raw materials quality.
The objective of the invention is to realize like this:
The double screw extruder of spout band screen pack of the present invention; 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 invention has the beneficial effects as follows:
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 spout band screen pack of the present invention.
Fig. 2 is the vertical view of storage bin top spout in the double screw extruder of spout band screen pack of the present invention.
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 present invention relates to a kind of double screw extruder of spout band screen pack, comprise 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)
