The anti-reflux quantitative filling equipment comprises a flow measurement control device, a liquid tank, a manual valve, a filling pump, a balance check valve, a flow transducer, a one-way valve and a discharge pipe. The liquid tank is connected with the discharge pipe through a pipeline; the manual valve, the filling pump, the flow transducer and the one-way valve are sequentially arranged on the pipeline in the direction from the liquid tank to the discharge pipe; the balance check valve is arranged at an outlet pipeline of the filling pump and is connected with an inlet pipeline of the filling pump through a reflux pipe; the flow measurement control device controls and is connected with the filling pump, the flow transducer and the one-way valve, quantitative filling is achieved, reflux can be prevented, waste and leakage of chemical liquid are avoided, and the environmental protection performance is improved.
Description
Technical field
The utility model relates to chemical liquid Canning Technique field, relates in particular to a kind of counterflow-preventing quantitative filling device.
Background technology
PCB wiring board is one of vitals of electronics industry, almost every kind of electronic machine, little of accutron, calculator, large to computing machine, 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.These chemical liquids need filling transport, and existing filling apparatus cannot quantitative filling, causes chemical liquid waste even to reveal and form, and affects environmental protection, also likely occurs the situation of liquid countercurrent when filling.
Summary of the invention
The purpose of this utility model is to provide a kind of counterflow-preventing quantitative filling device for the deficiencies in the prior art, can also can prevent adverse current by quantitative filling, avoids chemical liquid waste and reveals, and improves environmental-protecting performance.
For achieving the above object, the utility model adopts following technical scheme: a kind of counterflow-preventing quantitative filling device, and it comprises flow metering controller, flow container, manually-operated gate, filling pump, balance check (non-return) valve, flow transmitter, check valve and discharge nozzle; Described flow container connects described discharge nozzle by pipeline, the pipeline from flow container to discharge nozzle direction, described manually-operated gate, filling pump, flow transmitter and check valve is installed successively; Described balance check (non-return) valve is arranged at the export pipeline place of filling pump, and balance check (non-return) valve connects the entrance pipe place of described filling pump by reverse stream pipe; Filling pump, flow transmitter and check valve described in flow metering controller control linkage.
Described discharge nozzle is telescopic pipe.
Described discharge nozzle is provided with filling rifle.
The utility model beneficial effect is: a kind of counterflow-preventing quantitative filling device described in the utility model, adopt the filling amount of flow metering controller control, and can also can prevent adverse current by quantitative filling, avoid chemical liquid waste and reveal, improve environmental-protecting performance.
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, a kind of counterflow-preventing quantitative filling device described in the utility model, it comprises flow metering controller 8, flow container 1, manually-operated gate 2, filling pump 3, balance check (non-return) valve 9, flow transmitter 4, check valve 5 and discharge nozzle 6; Described flow container 1 connects described discharge nozzle 6 by pipeline, and described manually-operated gate 2, filling pump 3, flow transmitter 4 and check valve 5 are installed the pipeline from flow container 1 to discharge nozzle 6 directions successively; Described balance check (non-return) valve 9 is arranged at the export pipeline place of filling pump 3, and balance check (non-return) valve 9 connects the entrance pipe place of described filling pump 3 by reverse stream pipe 10; Filling pump 3, flow transmitter 4 and check valve 5 described in flow metering controller 8 control linkages.Preferably, described discharge nozzle 6 is telescopic pipe, and the filling bucket of being convenient to being placed on diverse location carries out filling.Preferably, described discharge nozzle 6 is provided with filling rifle 7, and filling rifle 7 inserts in filling bucket, convenient operation.
When filling, in flow metering controller 8, set filling amount, open manually-operated gate 2, filling pump 3 moves, and chemical liquid enters discharge nozzle 6 along pipeline, poured in filling bucket by filling rifle 7 again, flow transmitter 4 is monitored real-time data on flows, and feeds back in flow metering controller 8 and show, when reaching while setting filling amount, flow metering controller 8 is controlled filling pump 3 and is stopped action, and controls check valve 5 and close.Change an empty filling bucket, repeat aforesaid operations.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 pouring process, the liquid of adverse current is got back to the entrance of filling pump 3 by balance check (non-return) valve 9 and reverse stream pipe 10, avoids adverse current to return flow container 1 and affects the quality of flow container 1 interior chemical liquid.Described a kind of counterflow-preventing quantitative filling device, adopts flow metering controller 8 to control filling amount, can also can prevent adverse current by quantitative filling, avoids chemical liquid waste and reveals, and improves environmental-protecting performance.
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.
