Abstract
The invention provides a continuous flow self-adjusting dosing device. The dosing device comprises a shell, an inner piston, a water inlet pipe and a water outlet pipe, wherein the shell is provided with two dosing ports, two displacement switches and two three-way electromagnetic valves; the inner piston is arranged in the shell and precisely matched with the shell to divide the shell into left and right chambers; the inner piston can freely slide in the shell; the left and right chambers have good sealing property, so the liquid does not flow across; the displacement switches control two connected pipelines of the two three-way electromagnetic valves by adopting point contact control; and the displacement switches control a batcher to dose medicament into the chambers at the dosing ports. The inlet and outlet water can be dynamically adjusted, and the dosing concentration of the outlet water is consistent.
Description
Technical field
What the present invention relates to is a kind of apparatus for combining liquids, and what relate in particular to is that a kind of Continuous Flow self-regulation adds about device.
Background technology
Doser always is the requirement of biology, medical field, and particularly the diphasic anaerobic fermentation technique of bio anaerobic fermentation needs dosing in the reactor running, and first of reactor goes out water unstable mutually, and produce methane intake relatively require very high.But existing doser all is a convection cell carries out direct dosing, and can there be very big difference in the fluid after the dosing in the mixed effect of different time like this, and experiment or medical treatment are caused very big influence; Existing in addition self-timing doser, little to flow velocity, the fluid dosing error of flow velocity shakiness can be very big, and cause complicated difficult the popularization and maintenance of equipment.
Summary of the invention
But the object of the present invention is to provide a kind of self-regulation, can realize that the Inlet and outlet water flow equates, and the uniform continuous flow self-adjusting dosing device of dosing.
The object of the present invention is achieved like this:
Its composition comprises housing, inner carrier, water inlet pipe, outlet pipe, housing is provided with two dosing mouths, two position deactivation switches and two three-way magnetic valves, two chambers about inner carrier is arranged at and in the housing and with the housing precision-fit housing is divided into, inner carrier can be free to slide in housing, but the sealing of left and right sides chamber is good, the liquid that can not crossfire, the position deactivation switch adopts two kinds of some touch-control system, two three-way magnetic valves of control to connect pipeline, and the dosing mouth dosing is also by the dosing in chamber of position deactivation switch control batcher.
In order to solve the problem that exists in the prior art, a kind of continuous flow self-adjusting dosing device of the present invention's design.Mainly form by housing, inner carrier, dosing mouth, position deactivation switch and two three-way magnetic valves.Housing and inner carrier are made by stainless steel material, dosing mouth and position deactivation switch all are wrapped in entirely by high-quality plastics, the pipe path of three-way magnetic valve is a plastic material, inner carrier and housing precision-fit, inner carrier can be free to slide in housing, but the sealing of left and right sides chamber is good, the liquid that can not crossfire, the position deactivation switch adopts some touch-control system, can control two kinds of two three-way magnetic valves and connect pipeline, and the dosing mouth dosing is also by the dosing in chamber of position deactivation switch control batcher.But whole doser self-regulation realize that the Inlet and outlet water flow equates, and dosing is even.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
The composition of continuous flow self-adjusting dosing device of the present invention comprises housing 9, inner carrier 7, left side water inlet pipe 11, right water inlet pipe 12, left side outlet pipe 21, right outlet pipe 22, housing is provided with left dosing mouth 51, right dosing mouth 52, position, left side deactivation switch 61, right position deactivation switch 62 and two three-way magnetic valves, two chambers about inner carrier is arranged at and in the housing and with the housing precision-fit housing is divided into, inner carrier can be free to slide in housing, but the sealing of left and right sides chamber is good, the liquid that can not crossfire, the position deactivation switch adopts some touch-control system, connect pipeline for two kinds of two three-way magnetic valves of control, the dosing mouth dosing is also by the dosing in chamber of position deactivation switch control batcher.
The course of work of the present invention is: fluid enters from general import 1, suppose that piston 7 moves just from left to right, then left magnetic valve suitable for reading 41 is opened, end opening 42 is closed, right magnetic valve suitable for reading 31 cuts out, end opening 32 is opened, because left chamber 81 is communicated with water inlet pipe 11, then the pressure of left chamber 81 is greater than right chamber 82, piston 7 just moves right according to corresponding speed along with the size of flow of inlet water, water outlet 2 is just flowed out with identical flow velocity with water inlet 1, and when piston 7 was run into right position deactivation switch 62, this moment, left magnetic valve suitable for reading 41 cut out, end opening 42 is opened, right magnetic valve suitable for reading 31 is opened, and end opening 32 is closed, and doser 51 is to left chamber's 81 dosings, it is fully mixed with water inlet, piston 7 beginnings are moved from right to left, and this moment, water inlet was entered by right inlet channel 12, and water outlet is come out by left outlet pipe 21 roads.Because design of the present invention, Inlet and outlet water can be realized dynamic adjustments, and the adding consistency unanimity of water outlet.
Claims (1)
1. continuous flow self-adjusting dosing device, its composition comprises housing, inner carrier, water inlet pipe, outlet pipe, housing is provided with two dosing mouths, two position deactivation switches and two three-way magnetic valves, it is characterized in that: two chambers about inner carrier is arranged at and in the housing and with the housing precision-fit housing is divided into, inner carrier can be free to slide in housing, but the sealing of left and right sides chamber is good, the liquid that can not crossfire, the position deactivation switch adopts some touch-control system, connect pipeline for two kinds of two three-way magnetic valves of control, the dosing mouth dosing is also by the dosing in chamber of position deactivation switch control batcher.
