Description
Technical Field
The utility model relates to a screw press, in particular to a screw press outlet plugging device.
Background
The screw squeezer is mainly applied to drying and dewatering of household garbage, kitchen waste and kitchen, dewatering of waste plastic film after cleaning, dewatering and compression of grid residue or filter residue in industrial wastewater treatment in industries of papermaking, slaughtering, leather, textile and the like.
The back pressure of the traditional screw squeezer is established by adopting a mode of a cylinder or a spring at the tail part of the variable diameter and the variable pitch of the main shaft, in order to ensure enough extrusion force, the main shaft is designed longer, the processing difficulty is high, the problem that the squeezing force is insufficient and the water content of the extruded material is still high still exists
Disclosure of Invention
In order to solve the problems, the utility model provides an outlet plugging device of a screw press, which can apply stable back pressure and can adjust the back pressure.
The technical scheme of the utility model is as follows:
an outlet plugging device of a screw press is arranged in a discharge port of a single screw press; the plugging device comprises two plugging plates, wherein the two plugging plates are hinged to a discharge port of the single screw squeezer, the two plugging plates are opened and closed, and a discharge channel is formed between the two plugging plates and the discharge port of the single screw squeezer; the material passes through the discharge channel and forms an included angle of more than 90 degrees with the two plugging plates;
the plugging device further comprises a force application mechanism, wherein the force application mechanism is respectively connected with the two plugging plates and applies pressure to the two plugging plates, and the pressure is converted into back pressure of extruded materials through the two plugging plates.
The force application mechanism is two hydraulic cylinders, and the two hydraulic cylinders are both arranged on a discharge hole of the single screw squeezer and are respectively connected with the two plugging plates.
The two hydraulic cylinders simultaneously form a driving mechanism of the two plugging plates to drive the two plugging plates to open and close.
Both plugging plates are formed by bending stainless steel plates; the inlet of the discharging channel is large, and the outlet is small.
The utility model has the advantages of reasonable design, simple structure, design of two plugging plates, application of pressure to the two plugging plates by using the force application mechanism to form back pressure for extruding materials, no need of changing pitch and diameter to generate back pressure, shortening of screw length, simplification of screw structure, lower manufacturing cost of the screw spindle, easy adjustment of back pressure, and obviously better water content of the extruded materials than the traditional structure.
