Background

The traditional paper-making pulping refers to a production process of dissociating plant fiber raw materials into natural color or bleached pulp by a chemical method, a mechanical method or a combination method of the chemical method and the mechanical method, and the generally adopted technical process comprises the steps of crushing, cooking, washing, screening, bleaching, purifying and drying the plant fiber raw materials.

In the above process, the pulp needs steady flow degassing to avoid pressure pulses inside the fluid, which is detrimental to the formation of the paper, while the presence of bubbles can affect the quality of the paper. Therefore, the existing pulp supply system is often provided with pulp stabilizing equipment, but the simple pulp stabilizing equipment has poor effect and cannot better meet the requirement of steady flow degassing.

In addition, in the process flow of the paper-making pulping treatment, the pressure pulse of the fluid can also influence the process quality or equipment, the flow flowing rate of the traditional paper-making pulping process flow pipeline is controlled by measures such as pipelines, valve control and the like, and the pulse fluctuation of the fluid in the pipelines is ignored. And the automatic control through valves and the like can not realize stable operation, is greatly influenced by the outside and has high cost. However, the pulse influence of fluids such as pulp and the like is not deeply researched in the existing papermaking and pulping process, so that the process flow is unstable and no reason can be found.

To sum up, for solving the structural not enough of current papermaking pulping equipment, the utility model designs a rational in infrastructure, excellent in use effect's paper pulp current stabilizer.

Detailed Description

The technical solution of the present invention will be further explained with reference to the following embodiments and accompanying drawings.

As shown in fig. 1 and 2, the present pulp flow stabilizer includes:

the tank body 10 is internally provided with two clapboards 31 in parallel, the two clapboards 31 surround to form a mixing cavity 11, two shunting cavities 12 are symmetrically arranged at two sides of the mixing cavity 11, and the mixing cavity 11 is respectively communicated with the two shunting cavities 12;

the hopper sets up to a plurality of, and each hopper is located jar body 10 bottoms and corresponds the setting with each cavity, and the hopper includes feeder hopper 21 and divides two play hoppers 22 of arranging in feeder hopper 21 both sides, this feeder hopper 21 and 11 UNICOMs of hybrid chamber, and every goes out hopper 22 and all communicates with the reposition of redundant personnel chamber 12 that corresponds, and paper pulp is by supreme down entering hybrid chamber 11 back misce bene through feeder hopper 21, and then shunts to bipartition chamber 12 to further export outwards via two play hoppers 22.

In the paper-making pulping treatment process flow, the pressure pulse of fluid can affect the process quality or equipment, the flow flowing quantity of the existing paper-making pulping process flow pipelines is controlled by measures such as pipelines, valve control and the like, and the pulse fluctuation of the fluid in the pipelines is ignored. Because the stable operation can not be realized through the automatic control of a valve and the like, the influence of the outside is large, the cost is high, and the pulse influence of fluids such as pulp and the like is not deeply researched in the conventional papermaking and pulping process, so that the process flow is unstable.

Therefore, the utility model provides a paper pulp flow stabilizer, which ensures that paper pulp is uniformly distributed from the mixing cavity 11 and enters the distribution cavities 12 at two sides according to the arrangement of the baffle plate 31 and the fluid mechanics principle that the liquid level overflow amount of liquid at the same height is the same, thereby ensuring that the paper pulp is uniformly distributed and controllably distributed; meanwhile, the pulp enters the diversion cavity 12 from the mixing cavity 11 and flows in a dead weight mode, so that the pulse influence on the cavity is avoided, and the flow stabilizing effect is realized.

Specifically, two partition plates 31 are arranged in the tank body 10, the bottoms of the partition plates 31 are fixedly connected with the tank body 10, and the tops of the partition plates 31 are far away from the top of the tank body 10, namely the height of the partition plates 31 is lower than that of the inner space of the tank body 10, so that the pulp can be divided from the mixing cavity 11 and enter the dividing cavity 12 through the structural design; and because the two clapboards 31 have the same height, the paper pulp is uniformly distributed to two sides from the mixing cavity 11, and the uniform distribution is ensured.

The bottom of each cavity is correspondingly provided with a hopper, preferably, each hopper is respectively connected with the corresponding cavity in a sealing way, and each hopper is arranged in an inverted conical shape.

Wherein, the mixing chamber 11 bottom is feeder hopper 21, and reposition of redundant personnel chamber 12 bottom is out hopper 22, and each hopper structure sets up unanimously, and the during operation, paper pulp gets into mixing chamber 11 through feeder hopper 21 and mixes, and then shunts to two reposition of redundant personnel chambers 12, exports outward via two play hoppers 22 at last.

The hopper is the toper form setting of invering here, and the paper pulp fair current of being convenient for on the one hand is down, reduces the pulse and avoids the residue to pile up, and on the other hand, when the end during operation, can not remain more residue in the jar body 10, need not to dismantle jar body 10, direct input clear water wash can, clear up effectually, it is convenient to use.

In this embodiment, the hopper is preferably hermetically connected to the corresponding cavity, and the can body 10 and the hopper may be integrally formed during actual manufacturing, which depends on actual use conditions and is not limited herein.

Preferably, a baffle 32 is installed in the mixing chamber 11, the baffle 32 is located at one third of the height of the mixing chamber 11, the front end and the rear end of the baffle 32 are respectively fixedly connected with the inner wall of the mixing chamber 11, and gaps are respectively reserved between the two sides of the baffle 32 and the two partition plates 31.

In this embodiment, it is preferable that the baffle 32 is disposed in the mixing chamber 11, and the baffle 32 is fixedly connected with the inner wall of the mixing chamber 11 in the front and back directions, where the baffle 32 is disposed to prevent the pulp from splashing due to excessive pressure when entering the mixing chamber 11, and stop the pulp liquid, and on the other hand, the mixing of the pulp in the mixing chamber 11 is actually performed in the space above the baffle 32, so that the baffle 32 is preferably located at one third of the height of the mixing chamber 11, and the pulp can be uniformly mixed above the baffle 32.

Meanwhile, a gap is reserved between the two sides of the baffle 32 and the two partition plates 31 respectively, the gap is relatively large, so that paper pulp can flow conveniently, and the paper pulp can be fully and uniformly mixed in the mixing cavity 11.
