Problems solved by technology

[0004] The disadvantage of the eccentric feeding high consistency refiner with this structure is that it can only be used for refining high consistency fiber raw materials, and cannot control the feeding speed
Since the refining quality of the high-consistency refiner has a great relationship with its feeding speed, the eccentric-feed high-consistency refiner with this structure cannot guarantee the stability of its refining quality; in addition, some high-consistency fibers The fibers in the raw material will be entangled with each other and form a group, which will cause the feed screw to be stuck and the refiner to fail to feed normally.

Embodiment Construction

[0008] The embodiment of the eccentric feed high-consistency refiner with feed metering device of the present invention will be further described below in conjunction with the accompanying drawings.

[0009] The high-concentration fiber raw material to be grinded first enters the weighing hopper. When the two parallel and non-contact horn rollers in the weighing hopper rotate in opposite directions at the set speed, the horn thorns distributed on the roller surface can transfer the raw material On the other hand, the broken raw materials can be dropped into the feeding screw barrel at a constant speed. The metered high-concentration fiber raw material enters between the fixed grinding plate and the rotating grinding plate under the push of the feeding screw, and the high-consistency fiber raw material is brought into the plane refining area by the grinding teeth on the rotating grinding plate, and the fixed grinding plate changes from deep to Shallow arc-shaped grooves can mak...

Abstract

The invention relates to an eccentric-feeding high-consistency pulping machine with a feed metering device. The pulping machine comprises a shell, a front end cover, a metering hopper and a feeding screw, a disc-shaped moving disc, a rotating abrasive disc and a fixed abrasive disc, an abrasive disc clearance adjusting mechanism and a transmission device. According to the invention, the feeding speed of the pulping machine is controlled so as to ensure the stability of pulping quality; meanwhile, flocculated and agglomerated fibre raw materials can be dispersed so as to avoid locking of the screw.

Description

(1) Technical field [0001] The invention relates to a high-consistency refining equipment in the pulp and paper industry, in particular to an eccentric feeding high-consistency refining machine with a feeding metering device capable of controlling the feeding speed. (2) Background technology [0002] The existing eccentric feeding high consistency refiner has a feeding screw fixed in front of the front end cover of the shell, a fixed grinding plate fixed behind the front end cover, and a circular feeding hole is opened on the front end cover and the fixed grinding plate to For feeding screw to penetrate. The shell is connected with the main shaft bearing box, and the shaft end of the main shaft in the shell is fixed with a circular moving disc, and the rotating disc is installed on the rotating disc, except for the mounting hole of the locking nut of the rotating disc in the center of the rotating disc and the mounting hole on the fixed grinding disc. Outside the feeding ho...
