DETAILED DESCRIPTION

[0017] The water reducing agent reactor capable of automatic sampling of the utility model is described below in conjunction with the accompanying drawings.

[0018] In the first embodiment of the present application, Figures 1 to 4As shown, the water reducing agent reactor capable of automatic sampling (hereinafter referred to as "this patent") includes a stirring motor 1, a gas phase material hole 2, a manhole 3, a material inlet hole 4, a jacket 5, a material outlet 6, a sampling component 7, a connecting pipeline 7-1, a sample suction tube 7-11, a return pipe 7-12, a sample suction pump 7-13, a sampling plate 7-2, a sampling plate shell 7-21, a sampling tube 7-22, an electric control valve 7-23, a sample bottle interface 7-24, a metering sensor 7-25, a sample bottle 7-3, a reactor body 8, a steam inlet 9 and a condensate outlet 10. The stirring motor 1 is fixedly installed on the top of the reactor body 8, and the gas phase material hole 2, the manhole 3 and the material inlet hole 4 are respectively installed on the upper side of the reactor body 8. The jacket 5 is sleeved at the lower part of the reactor body 8. The lower end of the reactor body 8 is opened with a hole for installing the material outlet 6, the upper part of the jacket 5 is opened with a hole for installing the steam inlet 9, and the lower part of the jacket 5 is opened with a hole for installing the condensate outlet 10 The sampling assembly 7 is fixedly installed on the surface of the jacket 5, and the connecting pipeline 7-1 of the sampling assembly 7 passes through the jacket 5 to connect the reactor body 8. The connecting pipeline 7-1 is divided into a sample suction tube 7-11 and a return tube 7-12. A sample suction pump 7-13 is installed in the middle section of the sample suction tube 7-11. The sample suction tube 7-11 and the return tube 7-12 are respectively connected to the two ends of the sampling tube 7-22 installed in the sampling plate shell 7-21 of the sampling plate 7-2. Eight or six electric control valves 7-23 are arranged at equal intervals on the surface of the sampling tube 7-22. The electric control valve 7-23 is connected to the sample bottle 7-3 through a pipeline. The sample bottle 7-3 is fixedly connected to the surface of the sampling plate shell 7-21 through a sample bottle interface 7-24. A metering sensor 7-25 is provided in the sample bottle interface 7-24, and the metering sensor 7-25 extends into the sample bottle 7-3; the electric control valve 7-23 and the sample suction pump 7-13 are connected to the control machine in the sampling plate shell 7-21 through electric wires.

[0019] The utility model number of the polycarboxylic acid water-reducing agent reactor is CN206444593U (hereinafter referred to as "the patent"). The patent only exports the water-reducing agent in production through a detection outlet, and controls the opening and closing of the detection outlet through a valve. This means that the patent can only be sampled manually at a fixed time and at a fixed point, which is not very convenient to use. In addition, the crude sampling method also has the risk of water-reducing agent splashing and causing skin burns to the staff. The patent uses a fully automatic sampling component 7 to automatically complete sampling, which can effectively isolate the staff and the water-reducing agent, ensure the safety of the staff when sampling, and effectively reduce the workload of the staff when sampling through the automated sampling process.

[0020] The structure of the second embodiment is basically the same as that of the first embodiment, except that the metering sensor 7-25 is a rod-shaped plastic part, and an electrode is installed at the lower end and the middle section of the plastic rod respectively, and the electrodes are connected to the control machine in the sampling plate 7-2 through wires. The amount of water reducer entering the sample bottle 7-3 can be effectively controlled, that is, when the water reducer liquid level reaches the electrode at the upper part of the metering sensor 7-25, the upper and lower electrodes of the metering sensor 7-25 will be connected, so that the control machine controls the electric control valve 7-23 to close.

[0021] In order to further optimize the working efficiency of the present application and make the installation of the sample bottle 7-3 more stable, the sample bottle 7-3 is screwed to the sample bottle interface 7-24. In order to facilitate the staff to observe the state of the water reducer mother liquid in the sample bottle 7-3, the sample bottle 7-3 is made of tempered glass with a scale on the surface. In order to allow the water reducer to enter the sample bottle 7-3 better, the diameter of the sample suction tube 7-11 is larger than the return tube 7-12. In order to further facilitate the staff to observe the state of the water reducer, the sampling tube 7-22 and the sampling plate shell 7-21 are both made of transparent glass.

[0022] When in use, install the water reducer reactor capable of automatic sampling, connect the corresponding pipeline equipment and put it into use.

[0023] When the utility model is in use, the specific operations are as follows:

[0024] When in use, materials are added in a quantitative manner. After the reaction reaches a certain time point, the control machine in the sampling plate 7-2 controls the sample suction pump 7-13 to suck the water reducer in the reactor body 8 out of the sample suction tube 7-11 and send it into the sampling tube 7-22 of the sampling plate shell 7-21. At this time, the electric control valve 7-23 connected to the first sample bottle 7-3 is opened, and the water reducer flows from the sampling tube 7-22 into the sample bottle 7-3 through the pipeline, and the excess water reducer flows along the sampling tube 7-22 and the return pipe 7- 12 flows back into the reactor body 8. When the water reducer liquid level reaches the electrode on the upper part of the metering sensor 7-25, the upper and lower electrodes of the metering sensor 7-25 will be connected, so that the control machine controls the electric control valve 7-23 to close, so that the first sample bottle 7-3 is filled. The staff can observe the state of the water reducer at this time, and even remove the sample bottle 7-3 for testing. When the first sample bottle 7-3 is full, the control machine can control the subsequent other sample bottles 7-3 to take samples in turn.

[0025] In summary, the water reducer reactor capable of automatic sampling in the embodiment of the utility model, by adding a sampling component 7 capable of automatic sampling at regular intervals outside the reactor body 8, allows the staff to timely understand the current state of the water reducer, which can effectively improve the production quality of the electric water reducer, and can also effectively prevent the water reducer in production from splashing onto the staff, effectively protecting the safety of the staff.
