Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1-3, a water reducing agent reaction kettle convenient for sampling detection comprises a kettle body 1, wherein a sealing cover 2 is arranged on the upper part of the kettle body 1, a mounting opening 21 is formed in the sealing cover 2, a sampling tube 3 is hermetically arranged at the mounting opening 21 in a penetrating manner, the lower end of the sampling tube 3 extends to the inner bottom of the kettle body 1, a lifting tube 4 is slidably arranged in the sampling tube 3, and the outer wall of the lifting tube 4 is hermetically connected with the inner wall of the sampling tube 3; the lateral wall of sampling tube 3 sets up a plurality of thief hole 33 along length direction, thief hole 33 department sets up check valve 34, the inside of sampling tube 3 sets up the flexible pin of

locking check valve

34, 4 external connection samplers 5 of fall way, when needs are at one of them high sample time, 4 descends to push down the flexible pin of fall way 4, when the bottom opening of fall way 4 descends to the check valve 34 department of corresponding height, open check valve 34 through the suction of sampler 5, the material sucks in sampler 5 through fall way 4, move up fall way 4 after the sample is accomplished, the flexible pin resets and locks check valve 34 again. Simple structure, the convenience is to the material sample of each height in the cauldron body 1, raises the efficiency.
