Abstract
The utility model relates to a pipeline dosing device, which belongs to the technical field of the dosing device, and comprises a main pipeline, an auxiliary pipeline, a dosing opening and a pressure releasing liquid discharging opening; the pipeline dosing device is directly connected with a dosing medium pipeline, so that the required dosing medium is mixed with the medicine through an on-off valve. Compared with the ordinary dosing device, the pipeline dosing device has the advantages of simple structure, convenient operation and less investment.
Description
Technical field
The utility model belongs to the medicine adding device technical field, specifically is a kind of pipeline medicine adding device.
Background technique
In the industrial production such as petrochemical industry and medicine, usually need by regularly in some medium, adding medicament to improve the medium quality, to reconcile pH value, corrosion mitigation speed etc.Traditional medicine adding device generally all is made up of grug feeding jar and dosing pump and pipe-line system thereof, and counter investment is big, and the flow process complexity also needs special medicine system antifreezing measure winter.
Summary of the invention
The utility model provides a kind of pipeline medicine adding device, and its characteristics are structure and simple to operate, invests for a short time, does not need by the antifreezing measure beyond the dosing medium.
The utility model adopts following technological scheme to realize:
A kind of pipeline medicine adding device comprises main pipe, secondary duct, dosing mouth and pressure release liquid port, it is characterized in that main pipe and secondary duct form the loop, secondary duct has cut-off valve, main pipe has the upstream and downstream valve, and dosing mouth links to each other with main pipe, and main pipe also is connected with the pressure release liquid port; Described device directly is connected with palpus dosing medium pipeline.
The utility model open auxiliary pipeline cut-off valve at first when dosing, close the upstream and downstream valve of main pipe then, palpus dosing medium changes temporarily walks secondary duct, open the pressure release liquid port then, close liquid port after discharge opeing finishes, add the medicament that needs by dosing mouth, medicament adds to be opened the upstream behind the downstream valve of opening main pipe behind this device earlier and cuts down, close the secondary duct cut-off valve, medium is changeed back away main pipe, makes palpus dosing medium walk main pipe and mixes with medicine.
The utility model can be according to different operating modes, different rerum naturas, flow, medicament addition that must the dosing media etc., the material of regulating device, heat resisting and pressure resisting grade, specification.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1-main pipe, 2-secondary duct, 3-dosing mouth, 4-pressure release liquid port.
Embodiment
Embodiment
As shown in Figure 1, a kind of pipeline medicine adding device, comprise main pipe 1, secondary duct 2, dosing mouth 3 and pressure release liquid port 4, main pipe 1 forms the loop with secondary duct 2, secondary duct 2 has cut-off valve, main pipe 1 has the upstream and downstream valve, and dosing mouth 3 links to each other with main pipe 1, and main pipe 1 also is connected with pressure release liquid port 4.This device directly is connected with palpus dosing medium pipeline, open auxiliary pipeline 2 cut-off valves at first during dosing, close the upstream and downstream valve of main pipe 1 then, palpus dosing medium changes temporarily walks secondary duct 2, open pressure release liquid port 4 then, after finishing, discharge opeing closes liquid port 4, add the medicament that needs by dosing mouth 3, medicament adds to be opened the upstream behind the downstream valve of opening main pipe 1 behind this device earlier and cuts down, close secondary duct 2 cut-off valves, medium is changeed back away main pipe, makes palpus dosing medium walk main pipe and mixes with medicine, to reach the purpose of pipeline dosing.
