Embodiment 1

[0055] This embodiment is an automatic feeding process for pulp.

[0056] use as figure 1 As shown in the process flow, the pulp is sent to the hydropulper after unpacking, multi-stage conveying, automatic meal feeding and chain plate conveyance, and is mixed with lye in the hydropulper. The specific process flow can be The overview is as follows:

[0057] The packaged pulp is placed on the unpacking conveyor platform 2 by a forklift, and the conveying motor is started, and the pulp is sent to the bottom of the bale lifter by the nailed conveyor belt of the unpacking conveyor platform 2. The bale lifter is equipped with a lifting cylinder 3 and a clamping cylinder 4. The clamping cylinder 4 controls the manipulator 5 to clamp the pulp, and the lifting cylinder 3 is used to lift the pulp. For example, in a specific embodiment, the unpacking process flow is: adopt figure 2 The structure shown adopts the unpacking conveying platform 2 and the bale lifter arranged above the un...

Embodiment 2

[0065] Using the automatic pulp feeding process described in Example 1, the concentration of the porridge in the hydropulper was sampled and tested, and compared with the existing semi-automatic pulp feeding process, as shown in Table 1 below.

[0066] Table 1 Concentration comparison data of porridge

[0067]

[0068] In the raw liquid preparation process of viscose fiber production, the stability of the pressing and aging process can be guaranteed through the stability of the front-end pulp impregnation process.

[0069] In this embodiment, the function of pressing is to squeeze out excess lye, remove hemicellulose and impurities, and ensure the stability of a-cellulose content. In a specific embodiment, under the premise of the same pressing process, after adopting the pulp automatic feeding process described in Example 1, the qualified rate of the α-cellulose content in the pressing process is raised from 80% before it is not adopted to 95%.

[0070] The effect of agi...

Abstract

The invention discloses an automatic pulp feeding process which is characterized in that unpacked pulp is conveyed to a pulper after being sequentially subjected to multi-stage conveying, automatic pulp feeding and chain plate conveying, wherein the multi-stage conveying comprises at least two stages of conveying chains for continuous conveying, and every two adjacent stages of the conveying chains are matched to ensure that only a single package of pulp is conveyed on each stage of the conveying chains. According to the invention, through programmed control on multi-stage conveying of unpacked pulp, previous multi-stage and multi-bag simultaneous conveying is improved into multi-stage and single-bag conveying, so that continuous operation of equipment is ensured, and stability of automatic pulp feeding is realized.

Description

technical field [0001] The invention relates to an automatic pulp feeding process, in particular to an automatic pulp feeding process suitable for viscose production, and belongs to the technical field of viscose production. Background technique [0002] Viscose fiber is the full name of viscose fiber, which is divided into viscose filament and viscose staple fiber. Viscose fiber is a cellulose fiber produced from cotton or other natural fibers. The raw material used for viscose fiber is sheet pulp that has been cut, wrapped, and bundled. When feeding and pulping, it is necessary to remove the outer packaging of the pulp in sequence, and then transport it to a hydropulper to complete impregnation and stirring. Among them, the feeding and impregnation process is the primary process of viscose preparation, and the first chemical reaction in the viscose preparation process-cellulose alkalization occurs. The stability of feeding determines the quality of viscose production. ...
