Description
Technical field
The utility model relates to chemical liquid dispensing equipment technical field, relates in particular to reactor counterflow-preventing rationing equipment.
Background technology
PCB wiring board is one of vitals of electronics industry, almost every kind of electronic equipment, little of electronic watch, calculator, large to computer, communication electronic device, military armament systems etc., as long as there are the electronic devices and components such as integrated circuit, for the electric interconnection between them, all to use PCB wiring board.The Design and manufacture quality of PCB wiring board directly has influence on quality and the cost of whole product, even causes the success or failure of commercial competition.
At present, PCB wiring board is manufactured in process, need to use multiple chemical liquid, as alkaline etching liquid, acidic etching liquid, striping liquid are joined, micro-corrosion liquid, circuit developer solution etc.While producing these chemical liquids, need in reactor, react raw material, existing feed proportioning equipment cannot quantitative ingredient, inefficiency, and cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of reactor counterflow-preventing rationing equipment for the deficiencies in the prior art, automatically completes the work of quantitative ingredient reaction and can prevent adverse current, has greatly improved operating efficiency, has reduced cost.
For achieving the above object, the utility model adopts following technical scheme: reactor counterflow-preventing rationing equipment, and it comprises reactor, two cover raw material quantitative ingredient sectors; Described raw material quantitative ingredient sector comprises flow measurement controller, head tank, manually-operated gate, dosing pump, balance check (non-return) valve, flow transmitter, check valve and discharge nozzle; Described head tank connects described discharge nozzle by pipeline, the pipeline from head tank to discharge nozzle direction, described manually-operated gate, dosing pump, flow transmitter and check valve is installed successively; Described balance check (non-return) valve is arranged at the export pipeline place of dosing pump, and balance check (non-return) valve connects the entrance pipe place of described dosing pump by reverse stream pipe; Dosing pump, flow transmitter and check valve described in described flow measurement controller control connection; Discharge nozzle two feeding ends of coupled reaction still respectively of described two cover raw material quantitative ingredient sectors.
In described reactor, be provided with agitator.
In described reactor, be provided with level sensor.
The utility model beneficial effect is: reactor counterflow-preventing rationing equipment described in the utility model, and automatically complete the work of quantitative ingredient reaction and can prevent adverse current, greatly improve operating efficiency, reduce cost.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, reactor counterflow-preventing rationing equipment described in the utility model, it comprises reactor 60, two cover raw material quantitative ingredient sectors; Described raw material quantitative ingredient sector comprises flow measurement controller 8, head tank 1, manually-operated gate 2, dosing pump 3, balance check (non-return) valve 9, flow transmitter 4, check valve 5 and discharge nozzle 6; Described head tank 1 connects described discharge nozzle 6 by pipeline, and described manually-operated gate 2, dosing pump 3, flow transmitter 4 and check valve 5 are installed the pipeline from head tank 1 to discharge nozzle 6 directions successively; Described balance check (non-return) valve 9 is arranged at the export pipeline place of dosing pump 3, and balance check (non-return) valve 9 connects the entrance pipe place of described dosing pump 3 by reverse stream pipe 10; Dosing pump 3, flow transmitter 4 and check valve 5 described in described flow measurement controller 8 control connections.Discharge nozzle 6 two feeding ends of coupled reaction still 60 respectively of described two cover raw material quantitative ingredient sectors.Preferably, in described reactor 60, be provided with agitator, make reaction more abundant.Preferably, in described reactor 60, be provided with level sensor, can the interior liquid level of Quorum Sensing still 60, avoid the too high impact of liquid level to produce.
The operation principle of raw material quantitative ingredient sector is: when batching, in flow measurement controller 8, set dosage, open manually-operated gate 2, dosing pump 3 moves, and chemical liquid enters discharge nozzle 6 along pipeline, entered in reactor 60 by discharge nozzle 6 again, flow transmitter 4 is monitored real-time data on flows, and feeds back in flow measurement controller 8 and show, when reaching while setting dosage, flow measurement controller 8 is controlled dosing pump 3 and is stopped action, and controls check valve 5 and close.In the time that equipment shuts down, close manually-operated gate 2 and avoid revealing.Owing to being provided with balance check (non-return) valve 9, in blending process, the liquid of adverse current is got back to the porch of dosing pump 3 by balance check (non-return) valve 9 and reverse stream pipe 10, avoids adverse current to return head tank 1 and affects the quality of head tank 1 interior raw material.
Use two cover raw material quantitative ingredient sectors, different raw material quantitatives is dispensed in reactor 60 and is reacted, automatically complete the work of quantitative ingredient reaction, greatly improved operating efficiency, reduced cost.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
