Problems solved by technology

If the beating quality of this pool (batch) of pulp does not meet the requirements, it can only be known after the paper is discharged, but a certain amount of unqualified pulp has been stored
②Long process will not only increase facilities such as slurry tank, slurry pump, agitator, but also occupy the factory building, and also need to consume manpower, power, etc.

Embodiment 1

[0023] A high-consistency metering refiner, comprising a thickening device 1, a beating device 2 and a metering device 3, the thickening device, the beating device and the metering device are coaxially arranged, the thickening device outputs to the beating device, and the beating device outputs to the metering device, A water-sealed bearing frame 4 for supporting the shaft is arranged in the thickening device and the beating device, and the connection between the metering device and the thickening device and the shaft between the metering device and the beating device is carried out by means of a universal joint assembly 5 and a connecting shaft 6 Connection, that is, universal joints are arranged at both ends of the connecting shaft, and then respectively connected with the thickening device or the beating device through the universal joints, and the shaft 8 is driven by a stepless motor. The high-consistency metering refiner also includes a dilution zone 7, which connects the...

Embodiment 2

[0026] The parts not described in this embodiment are basically the same as in Embodiment 1, except that the thickening device first outputs to the metering device, and the metering device outputs to the beating device, and a water-sealed bearing frame for supporting the shaft is arranged in the thickening device and the beating device. The connection between the metering device and the thickening device and the shaft between the metering device and the beating device is connected by a universal joint assembly plus a connecting shaft, that is, universal joints are arranged at both ends of the connecting shaft, and then respectively connected with the Thickening device or beating device is connected, and the shaft is driven by a stepless motor.

[0027] The parts not described in this embodiment are the same as those in Embodiment 1.

Abstract

The invention discloses a high-concentration metering grinder which comprises a concentration device, a beating device and a metering device. The concentration device, the beating device and the metering device are coaxially arranged, the concentration device outputs pulp to the beating device, the beating device outputs the pulp to the metering device, or the concentration device outputs the pulp to the metering device, the metering device outputs the pulp to the beating device, a water seal bearing bracket for supporting a shaft is arranged in the concentration device and the beating device, the metering device is connected with the concentration device and the shaft of the beating device through universal joint assemblies and connecting shafts, namely, universal joints are arranged at two ends of each connecting shaft, the connecting shafts are respectively connected with the concentration device or the beating device through the universal joints, and the shaft is driven by an electrodeless. Equipment is greatly simplified, and the high-concentration metering grinder integrates three main functions of concentration, beating and metering and is a multi-purpose papermaking device.

Description

technical field [0001] The invention relates to a pulp refiner, in particular to a high-concentration metering refiner. Background technique [0002] The raw material (plant fiber) for the production of paper or cardboard is suspended in water and called slurry before papermaking. In order to make it have a certain production and papermaking performance, and more importantly, to make the physical properties of the paper (board) meet the quality requirements, it is necessary to perform a certain beating treatment on the pulp. In the traditional papermaking process, the two processes of beating treatment and paper machine production are intermittent and discontinuous. In order to ensure the continuous progress of subsequent papermaking production, it is necessary to store a considerable amount of pulp that has undergone beating and other treatments in the stock tank. When production needs to be processed, it will be sent to the paper machine to make paper. The basic process i...
