Abstract

The utility model relates to a pulp milling machine with double disks, comprising a base, a motor, a rotary disk, and a machine body. A shaft of the motor is provided with the rotary disk. The rotary disk is arranged in the machine body. A sealing pat is arranged between the shaft of the motor and the machine body. The motor and the machine body are fixedly arranged on the base. The shaft of the motor is sheathed with a spline housing. The rotary disk is sheathed on the spline housing. Because the utility model adopts the direct connection between the spline housing and the rotary disk, and the connection is in a gap matching mode, the utility model omits a shaft coupling, a long shaft, and a bearing which all increase energy consumption and occupy more area in the prior art, and thus, the utility model has the advantages of simple and compact structure, small size, convenient maintenance, low energy consumption, and high pulp making efficiency.

Description

Double disc refiner

The utility model belongs to the refining equipment of papermaking equipment, specifically is a kind of double disc refiner.

In paper industry, has the continuous beating effect at present owing to double disc refiner, so obtained promoting the use of in a big way, but existing double disc refiner is in use found the long main shaft that drives rolling disc and is supported by pair of bearings, seal point on the bearing is more, long main shaft connects with motor shaft by shaft joint again, thereby makes the mill structure complexity, and energy consumption is big, rotational efficienty is low, the deficiency that floor space is many.

It is a kind of simple and compact for structure that the purpose of this utility model is to provide, and volume is little, and energy consumption is low, and is easy to maintenance, the high double disc refiner of making beating efficient.

The utility model is realized by technical scheme once:

It is a kind of double disc refiner, comprise base, motor, rolling disc and body, rolling disc is installed on the motor shaft, rolling disc is installed in the body, between motor shaft and the body sealing gasket is installed, motor and body are fixedly mounted on the base, it is characterized in that being set with spline housing on the motor shaft, and rolling disc is sleeved on the spline housing.

Leave the free gap between described rolling disc and the spline housing.

Leave the free gap between described spline housing and the motor shaft.

The utility model owing to adopted spline housing and rolling disc directly to connect, and be the mode of matched in clearance compared with prior art, saved increase in the prior art more than energy consumption, the floor space shaft coupling, major axis and bearing, so have the following advantages:

1, simple and compact for structure, volume is little, and is easy to maintenance.

2, energy consumption is low, making beating efficient height.

Describe in further detail below in conjunction with accompanying drawing:

Fig. 1: the utility model example structure schematic diagram.Among the figure: 1 base, 2 motors, 3 spline housings, 4 rolling discs, 5,9 charging apertures, 6 abrasive discs, 7 bodies, 8 move seat, 10 casings, 11 manual pressure devices, 12 discharging openings, 13 positioning keys

Motor 2 and body 7 usefulness bolting are connected on the base 1 that is placed to the precalculated position, connect servicing units such as going up pipe, line in the usual way, mode of operation is identical with the course of work and prior art, 2 motor shafts of starter motor directly drive rolling disc 4 by the spline housing 3 on it and rotate, in charging aperture 5,9, put paper pulp into, after abrasive disc 6 through rotating ground, levigate paper pulp was discharged from discharging opening 12; When the distance between the abrasive disc 6 more greatly can not levigate paper pulp, move inwards along casing 10 by adjusting the mobile seat 8 of manual pressure device 11 promotions, spacing between abrasive disc 6 meets the fineness requirement of defibrination, because of being matched in clearance between spline housing 3 and the rolling disc 4, so when the gap of adjusting between the abrasive disc, rolling disc 4 can be on spline housing 3 cofree left sides, move right, (or spline housing 3 is by 13 left sides of the positioning key on the motor shaft, move right,) increase energy consumption in the prior art because of having saved, floor space many shaft coupling, major axis and bearing, so making beating efficient can improve 3～7%, splined shaft and body 7 can adopt mechanical seal or rubber seal.

Claims

1, a kind of double disc refiner, comprise base, motor, rolling disc and body, rolling disc is installed on the motor shaft, rolling disc is installed in the body, between motor shaft and the body sealing gasket is installed, motor and body are fixedly mounted on the base, it is characterized in that being set with spline housing on the motor shaft, and rolling disc is sleeved on the spline housing.
