Description

Rake type arch breaking device for calcium tank

Technical Field

The utility model relates to the field of PVC calendaring artificial leather, in particular to a rake arch breaking device for a calcium tank.

Background

Calcium powder (CaCO) ₃ ) Is an important filler in PVC calendaring artificial leather production, the dosage is only inferior to PVC resin powder, but the calcium powder is stored in a calcium tank for useIn the process, because the moisture absorption viscosity of the powder is increased, and the upper layer powder of the slender calcium tank compacts the powder at the discharge opening, or because the design of the calcium tank is not scientific, the calcium powder can arch at the discharge opening to cause the powder blocking at the discharge opening or unsmooth discharge of the calcium powder, and the normal calcium feeding of the screw conveyor is affected. The common arch breaking (anti-arching) method is as follows: 1) A vibration device is additionally arranged on the calcium tank to accelerate powder flow by vibration, so that the discharging is smooth; 2) The material raking device (see figures 1 and 2) is additionally arranged between the feeding port of the screw conveyor and the discharging port of the calcium tank, the material raking device comprises a material raking hopper 1, a central shaft 2 and a plurality of material raking blades 3, the material raking hopper 1 is vertically connected between the feeding port of the screw conveyor and the discharging port of the calcium tank, the central shaft 2 is horizontally and rotatably arranged in the material raking hopper 1 and is parallel to a main shaft of the screw conveyor, the material raking blades 3 are uniformly arranged on the central shaft 2 at intervals, and one end of the central shaft 2 is in transmission connection with one end of the main shaft of the screw conveyor through a chain transmission mechanism or a belt transmission mechanism. Both of these methods have a certain role in preventing arching, but each has its drawbacks. The adoption of vibration to accelerate the powder flow is limited in the powder flow process, and if the powder is improperly used, the powder at the discharge opening is compacted and arched; the material raking device is adopted to feed the screw conveyor, if the air humidity in summer is high, the moisture absorption viscosity of the calcium powder is greatly increased, or the shutdown time is slightly long, the upper layer powder in the calcium tank is used for compacting the powder at the discharge opening, the loosening property (fluidity) of the calcium powder is poor, the resistance of the material raking device is often excessively high, and the material raking blade of the material raking device is damaged or the central shaft is bent in a stretching way. In view of the defects of the two arch breaking methods and devices, we provide a rake arch breaking device for a calcium tank.
