此时，检测阀关闭，成品阀打开，合格溶液通过成品阀进入成品箱，待排空合格溶液后，关闭成品阀，重新开始一轮循环。At this time, the detection valve is closed, the finished product valve is opened, and the qualified solution enters the finished product box through the finished product valve. After the qualified solution is emptied, the finished product valve is closed to start a cycle again.
检修手阀的作用在于：水泵如果坏了，可以关闭手阀，然后取出水泵进行维修。排污阀的作用在于：定期清洗搅拌罐时，可以进行排污作业，此时不开水泵，避让污水污染后段管路。The function of the maintenance hand valve is: if the water pump is broken, you can close the hand valve, and then take out the water pump for maintenance. The function of the sewage valve is: when the mixing tank is cleaned regularly, the sewage operation can be carried out. At this time, the water pump is not turned on to avoid the sewage from polluting the downstream pipeline.
对于浓度的检测，还可以是：可以采用另外一款浓度检测器，置于搅拌罐内，进行实时检测，但存在溶液混合不均而导致的误检风险，同时维护性较差。For the detection of concentration, it can also be: another concentration detector can be used and placed in the stirring tank for real-time detection, but there is a risk of false detection caused by uneven mixing of the solution, and the maintainability is poor.
从以上的描述中，可以看出，本发明上述的实施例实现了如下技术效果：From the above description, it can be seen that the above-mentioned embodiments of the present invention have achieved the following technical effects:
本发明中的搅拌装置包括搅拌罐10和浓度检测管路20，搅拌罐10具有溶液出口部11和溶液回收口，浓度检测管路20的一端与溶液出口部11连接，浓度检测管路20的另一端与溶液回收口连接。这样，便可以通过对位于浓度检测管路20内的溶液进行浓度检测以判断位于搅拌罐10内的溶液浓度，并可以通过溶液回收口将位于浓度检测管路20内的溶液送回所述搅拌罐10内，进而实现搅拌罐10内的溶液循环，并实现对搅拌罐10内的溶液的浓度实时检测，解决了现有技术中的尿素溶液的浓度难以控制的问题。Stirring device among the present invention comprises stirring tank 10 and concentration detecting pipeline 20, and stirring tank 10 has solution outlet 11 and solution recovery port, and one end of concentration detecting pipeline 20 is connected with solution outlet 11, and concentration detecting pipeline 20 The other end is connected to the solution recovery port. In this way, it is possible to determine the concentration of the solution in the stirring tank 10 by detecting the concentration of the solution in the concentration detection pipeline 20, and the solution in the concentration detection pipeline 20 can be sent back to the stirring tank 10 through the solution recovery port. In the tank 10, the circulation of the solution in the stirring tank 10 is realized, and the real-time detection of the concentration of the solution in the stirring tank 10 is realized, which solves the problem that the concentration of the urea solution in the prior art is difficult to control.
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
