Abstract
The utility model provides a kind of chemicals adding set, belongs to feeding device field.Including paper pulp main pipeline, paper pulp main pipeline is equipped with constriction, and constriction is shunk by paper pulp main pipeline diameter to be formed, and penetrates paper pulp main pipeline equipped with chemical addition agent pipeline, and the discharge port of chemical addition agent is located in constriction.Can to avoid using metering pump, will not the use of electric energy spend.
Description
Technical field
The utility model provides a kind of chemicals adding set, belongs to feeding device field.
Background technique
Multi-chemical additive can be used in papermaking process.Especially speciality paper at production, some speciality paper is raw
Ten multiple additives can be used during production.The adding method of conventional additive is to take additive that supervisor is added with metering pumping
Road.The use of main problem existing for metering pump is that metering pump needs periodic maintenance or replacement, brings maintenance cost.Once metering pump
It breaks down, the amount of additives of addition is not up to standard to will cause biggish product quality accident.And the operation of metering pump needs
Electric energy is consumed, electric cost is higher.
Utility model content
The utility model mesh is to provide a kind of chemicals adding set, can be to avoid using metering pump, will not electric energy
Use cost.
Chemicals adding set described in the utility model, including paper pulp main pipeline, paper pulp main pipeline are equipped with contraction flow region
Point, constriction is shunk by paper pulp main pipeline diameter to be formed, and penetrates paper pulp main pipeline equipped with chemical addition agent pipeline, and chemistry adds
The discharge port of agent is added to be located in constriction.
The chemicals adding set, the interior pulp stream to trickle of paper pulp main pipeline pass through when flowing through constriction
There is the phenomenon that flow velocity increase in the flow section of diminution, fluid, and the size of flow velocity and flow section is inversely proportional.Flow velocity
Increase the reduction with Fluid pressure, since chemical additives pipeline protrudes into constriction, so the pressure outside discharge port is low
In the pressure in discharge port, to generate suction-operated, the chemical additives of required addition are sucked in paper pulp main pipeline, from
And complete adding procedure.
The chemicals adding set, constriction include shrinking feeding part, shrinking mixing portion and expansion discharging
Part is shunk feeding part expansion discharging portion and is connected to and shrink mixing portion both ends, the change of flow velocity is made to have a buffering
Process.
The utility model has the beneficial effect that compared with prior art
Using the variation of flow velocity, changes the pressure difference inside and outside chemical addition agent pipeline, chemical addition agent is made to be inhaled into paper pulp master
In pipeline, the application of metering pump is avoided, the electricity consumption for avoiding metering pump is spent, and maintenance and maintenance are spent, and is greatly reduced
Cost.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1, paper pulp main pipeline；2, chemical addition agent pipeline；3, constriction；3.1, discharging portion is expanded；3.2, it receives
Contracting mixing portion；3.3, feeding part is shunk.
Specific embodiment
The utility model embodiment is described further below with reference to the utility model:
Embodiment 1: as shown in Figure 1, chemicals adding set described in the utility model, including paper pulp main pipeline 1, paper pulp
Main pipeline 1 is equipped with constriction 3, and constriction 3 is shunk by 1 diameter of paper pulp main pipeline to be formed, and is equipped with chemical addition agent pipeline 2
Paper pulp main pipeline 1 is penetrated, and the discharge port of chemical addition agent is located in constriction 3.
Chemicals adding set described in the utility model, the interior pulp stream to trickle of paper pulp main pipeline 1 are flowing through contraction
When part 3, by the flow section of diminution, there is the phenomenon that flow velocity increase, the size of flow velocity and flow section in fluid
It is inversely proportional.The increase of flow velocity crosses the diameter for staying section by control constriction 3 with the reduction of Fluid pressure, can be accurate
Control extract the speed of chemical addition agent, completely instead of metering pump, and do not take into account that equipment damage metering is inaccurate and ask
Topic.
The chemicals adding set, constriction 3 include shrinking feeding part 3.3, shrinking mixing portion 3.2 and expand
Discharging portion 3.1 is opened, feeding part expansion discharging portion 3.1 is shunk and is connected to and shrink 3.2 both ends of mixing portion, make changing for flow velocity
Become the process for having a buffering.
