Abstract

The invention relates to the technical field of paraformaldehyde production, in particular to a double-roller type crushing device for paraformaldehyde production, which solves the problems of reduction of raw material crushing sufficiency and reduction of raw material crushing precision due to single utilization of rollers for crushing in the prior art, and comprises a crushing machine, wherein a feeding hole is formed in the upper side of the crushing machine, a through hole flange is formed in the upper side of a material injection shell, a feeding tube is fixed to the upper side of the material injection shell, a pair of crushing rollers which are oppositely arranged is arranged in the crushing machine, one ends of the crushing rollers make contact with a connecting belt, one end of a material conveying tube extends to a middle shell, and the interior of the middle shell is connected with a grinding block through a first motor; a through hole is formed in the bottom end of the middle shell, and a discharging tube is fixed through a screw; when a rotating rod rotates circumferentially, the connecting belt can be driven to move, the connecting belt can drive the pair of crushing rollers which are oppositely arranged to do circumferential motion in the same direction, so that crushing machining of paraformaldehyde production raw materials is completed.

Description

technical field [0001] The invention relates to the technical field of paraformaldehyde production, in particular to a pair-roll crushing device for paraformaldehyde production. Background technique [0002] Paraformaldehyde with a low degree of polymerization can replace ordinary industrial formaldehyde aqueous solution, and it can not only reduce the energy consumption of dehydration, but also greatly reduce the waste water treatment in various downstream products of formaldehyde such as synthetic pesticides, synthetic resins, paints and fumigation disinfectants. quantity. Paraformaldehyde with a low degree of polymerization has a higher active ingredient than industrial formaldehyde, and is a solid particle, which is beneficial to the chemical synthesis of chemical industry, pharmaceuticals and other industrial fields, especially in the synthesis that requires the use of anhydrous formaldehyde as a raw material, and has a wide range of uses . It can also be used as a di...
