Description

A kind of extruder reaction auxiliary adding equipment to prevent caking

technical field

The utility model relates to the technical field of reaction auxiliary agent addition equipment, in particular to an extruder reaction auxiliary agent addition equipment for preventing agglomeration.

Background technique

Auxiliary chemicals are auxiliary chemicals, also known as additives, added in industrial production to improve the production process, improve product quality and yield, or to give products a specific application performance. Most of the existing plastic granulation production uses extruder melt extrusion and then wire drawing and granulation. When the extruder is melted, powder additives need to be added. In actual production, most of the additives are fed by a feeder. Addition, but the powder particles of the powder additives are prone to generate static electricity, so that the powders are adsorbed together to form false agglomerates. After the block additives are added, the stirring time needs to be extended to stir the additives evenly, which reduces the production efficiency.

SUMMARY OF THE INVENTION

Aiming at the deficiencies of the prior art, the utility model provides an extruder reaction auxiliary agent addition device which can prevent the auxiliary agent from agglomerating.

The technical scheme of the utility model is: an extruder reaction auxiliary adding equipment for preventing caking, which is characterized in that: it comprises a screw feeder and a vibration pump, and the screw feeder is installed on the extruder through a mounting frame. On the left side of the machine, the mounting frame and the extruder are not in contact with each other. The screw feeder is composed of a feeding hopper, a discharging hopper, a screw motor and a reduction box. The bottom of the feeding hopper is connected with an outlet by bolts. A hopper, the left side wall of the discharge hopper is connected with a reduction box, the input shaft of the reduction box is connected with the motor shaft of the screw motor shaft, the output shaft of the reduction box is connected with the screw through a coupling, and the output shaft of the reduction box is connected with the screw. A discharge pipe is arranged on the right side wall of the hopper, and a vibration pump is installed above the discharge pipe through bolts.

Further, an auxiliary feeding port is provided on the left side of the top surface of the extruder and below the discharge pipe, one end of the extruder is connected with a motor, and the output end of the motor is connected to the extruder. Screw connection.

Further, the screw of the extruder rotates clockwise, and the discharge pipe is arranged on the opposite side of the screw, so that the auxiliary agent first falls on the screw for preheating and then enters the extruder for mixing.

Further, a lid is hinged on the top of the feeding hopper, a stirring motor is installed on the top of the lid through a bracket, a stirring shaft is connected to the motor end of the stirring motor, and a stirring blade is arranged on the stirring shaft.

Further, a rubber pad is provided at the connection between the feeding hopper and the discharging hopper.

Further, the extruder is a single-screw extruder.

The working principle of the present utility model:

When feeding additives, first open the cover, put the additives into the hopper, then close the material cover, and then turn on the stirring motor, screw motor and vibration pump at the same time. When it falls into the discharge hopper, the vibration pump generates vibration and transmits the vibration to the hopper. Due to the static electricity generated between the powder particles, the powder is adsorbed together to form false agglomerates. The vibration can disperse the agglomerated powder in the discharge hopper. The powder is put into the feed port through the discharge pipe and mixed with the material in the extruder.

The beneficial effects of the utility model are as follows: the utility model installs a vibrating pump on the outer wall of the discharging hopper, and the vibrating pump drives the discharging hopper to vibrate, thereby vibrating and dispersing the agglomerated powder in the discharging hopper, thereby preventing the adjuvant from agglomerating and improving the Production efficiency: By setting the discharge pipe on the reverse side of the screw, the additives will first fall on the screw for preheating and then enter the extruder for mixing.
