Problems solved by technology

[0004] The disadvantage of the eccentric feeding high consistency refiner with this structure is that its feeding system has no metering function, and the feeding screw only has the function of conveying and has no compression function.
When grinding high-consistency fiber raw materials, the quality of refining is unstable due to the inability to control the stable feed amount, and even feed blockage due to excessive feed; When feeding raw materials, it will also cause "back spray" accidents due to the low feed density of high-concentration fiber raw materials

Embodiment Construction

[0008] The embodiments of the eccentric feeding high-consistency refiner with a metering and compression feeding device of the present invention will be further specifically described below with reference to the accompanying drawings.

[0009] The eccentric feeding high-consistency refiner with the metering and compression feeding device of the present invention adopts two barbed claw rollers with controllable rotational speeds that rotate in opposite directions to control the amount of high-consistency fiber raw materials entering the metering feed hopper, and the compression feeding spiral The compression ratio ranges from 1.5-2.5. The high-concentration fiber raw material entering the metering feed hopper increases the density under the compression and push of the compression feeding screw with a stable feeding amount, and enters between the fixed grinding plate and the rotating grinding plate. The high-consistency fiber raw material or slurry is brought into the plane refi...

Abstract

The invention relates to an eccentric-fed high-concentration pulping machine with a metering and compressing feeding device. The pulping machine consists of a shell body, a front end cover, a metering hopper, a compressing feed screw, a disk-shaped moving disk, rotary grinding sheets, fixed grinding sheets, a grinding sheet gap adjusting mechanism and a driving device. The pulping machine can be applied to the pulping of high-concentration fiber raw materials and high-concentration pulp. The quality of pulped pulp can be controlled, and the production efficiency of pulping can be increased.

Description

(1) Technical field [0001] The invention relates to a high-consistency refining equipment in the pulp and paper industry, in particular to a belt that can grind various wood chips, straw chips and other fibrous raw materials into pulp or refine and thermally disperse high-consistency pulp Eccentric-fed high-consistency refiner with metered-compression feeding unit. (2) Background technology [0002] The existing eccentric feeding high-consistency refiner has a feeding screw fixed in front of the front end cover on the shell, a fixed grinding plate fixed behind the front end cover, and a circular feeding hole is opened on both the front end cover and the fixed grinding plate. For feeding screw penetration. The casing is connected with the bearing box of the main shaft, the shaft end of the main shaft in the casing is fixed with a circular moving disc, and the rotating disc is installed on the moving disc, except for the mounting hole of the moving disc locking nut in the cen...
