Pretreatment device and pretreatment method for breaking caking of ton bag

Abstract

The invention relates to the field of chemical product processing, in particular to a pretreatment device and a pretreatment method for breaking caking of a ton bag. The device comprises a conveying device, a lifting device, caking breaking devices, preliminary centring devices, final centring devices and a controller. The conveying device comprises a chain plate conveyor and a roller conveyor; the roller conveyor is arranged on a lifting platform in the lifting device; and the preliminary centring devices, the caking breaking devices and the final centring devices are sequentially arranged on two sides of the lifting device from bottom to top. The roller conveyor is fixed onto the lifting platform and moves up and down along with the lifting platform, so that the ton bag conveyed onto the roller conveyor can move up and down on the lifting device, caked materials in the ton bag are crushed in a classifying way, and the ton bag cannot be broken; and through signal transmission among sensors, centring sensors and the controller, the materials in the ton bag are completely crushed, meanwhile, the automated operation of the device is realized, and the labor force is greatly reduced.

Description

technical field [0001] The invention relates to the field of chemical product processing, in particular to a large-bag agglomeration pretreatment equipment and method. Background technique [0002] For compound fertilizer processing enterprises, since the ton bags can be reused more than 6 times, the extensive use of ton bags for packaging can greatly save the packaging cost of related products. However, in actual production, fertilizers such as monoammonium phosphate, ammonium chloride, and ammonium sulfate packed in tons of bags will inevitably agglomerate and harden gradually due to too long storage time, and the phenomenon of hardening will become more serious as time goes by, which will lead to extremely difficult unloading inconvenient. At present, the domestic scrapping method is generally to manually untie the big bag and then poke it, hit it with a sledgehammer or hit it with something. It is also easy to damage the driving and large bags. Contents of the invent...
