Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of synthetic instrument supporting equipment, and particularly relates to a liquid injection pipeline cleaning device. BACKGROUND
[0002] With the development of synthetic biology, the demand for synthetic primers is increasing; with the requirement of intelligent manufacturing, integration, platformization and modularization are the current trend. In order to cope with the more diversified needs of customers and better serve customers, simplify the production process and improve product performance. Provide another synthesis method for synthesis; enrich the existing product line.
[0003] During the use of the synthesizer, various reagents (commonly known as liquid injection) are injected through the pipeline. The end of the pipeline is generally equipped with a nozzle. After the liquid injection is completed, the reagent at the nozzle is prone to crystallization and solidification due to oxidation and other reasons, which affects the next use. Therefore, the residual reagent at the nozzle needs to be cleaned after the liquid injection is completed. There are two methods currently used. One is to flush the residual reagent off the inner wall of the cleaning pipeline by the inner wall of the pipeline. The current method for cleaning the inner wall of the liquid injection pipeline of the synthesizer on the market is basically in the form of a switching valve. When cleaning is needed, the switching valve is switched to the cleaning pipeline for cleaning. This method wastes the normal reagent (commonly known as dead volume) of the rear end (referring to the pipeline installed after the switching valve). Although there are many methods to reduce the dead volume, there are still some problems. In addition, since the two reagents are shared after switching, there is a risk of reagent confusion. Therefore, many one-way valves are added to make the pipeline crowded and complex. The other method is to use a brush to remove the residual reagent in front of the nozzle. This method currently relies on manual cleaning, which is low in efficiency and poor in cleaning effect. SUMMARY
[0004] The technical problem solved by the utility model is to provide a liquid injection pipeline cleaning device that uses a method to clean the outside of the outlet of the nozzle to remove the residual reagent at the nozzle opening and avoid the problem of deposition, oxidation and crystallization.
[0005] To solve the above technical problems, the utility model adopts one technical scheme: the utility model provides a liquid injection pipeline cleaning device, which comprises a valve seat integrated plate, a mounting plate, a reagent bottle, a liquid injection main pipe, a liquid injection branch pipe, a cleaning container, a cleaning main pipe and a cleaning branch pipe. The valve seat integrated plate is installed with a plurality of liquid injection valves and a plurality of cleaning valves. One end of the liquid injection main pipe is in communication with the reagent bottle, and the other end is in communication with the liquid injection valve. The liquid injection valve is also in communication with the corresponding liquid injection branch pipe. One end of each liquid injection branch pipe is integratedly installed on the mounting plate, and a liquid injection nozzle is installed at the end of each liquid injection branch pipe.
[0006] One end of the cleaning main pipe is communicated with the cleaning container, and the other end is communicated with the cleaning valve, and the cleaning valve is also communicated with corresponding cleaning branch pipes, one end of the cleaning branch pipes is integrally installed on the mounting plate, and a cleaning nozzle is installed at the end of each cleaning branch pipe.
[0007] Each cleaning nozzle is aligned with the corresponding liquid spraying nozzle.
[0008] Further, the cleaning nozzle is a stainless steel nozzle capable of being bent to adjust the height.
[0009] Further, the liquid spraying valve is a corrosion-resistant valve, and the cleaning valve is a common valve.
[0010] Further, the mounting plate is provided with a plurality of strip-shaped grooves arranged side by side, two mounting blocks are arranged at the strip-shaped grooves, each mounting block is provided with a semicircular cavity matched with the liquid spraying branch pipe and the cleaning branch pipe, and the semicircular cavities of the two opposite mounting blocks form a complete cavity.
[0011] Further, the mounting block and the mounting plate are detachably fixedly connected through fasteners.
[0012] Further, the mounting plate has a reagent channel for reagent passing and a cleaning channel for cleaning agent passing, the reagent channel is communicated with the liquid spraying main pipe, the liquid spraying valve and the liquid spraying branch pipe, and the cleaning channel is communicated with the cleaning main pipe, the cleaning valve and the cleaning branch pipe.
[0013] The beneficial effects of the present application are as follows:
[0014] The new pipeline cleaning device is adopted, the external part of the outlet of the nozzle is cleaned, the residual reagent of the nozzle outlet is removed, and the problem of deposition, oxidation and crystallization is avoided. Compared with the way of cleaning the inner wall of the pipeline by adopting a three-way switch valve in the prior art, the liquid spraying pipeline and the cleaning pipeline are completely separated, there is no dead volume, reagent is saved, and it is more beneficial for some expensive reagents.
[0015] Therefore, the present application can solve the problem of crystallization and blockage of the liquid spraying nozzle, and the reagent stored in the liquid spraying main pipe and the liquid spraying branch pipe can still be used next time, even if it is slightly contaminated and deteriorated, it can be discarded and excluded, and the amount of reagent used is saved.
