Description

Technical Field

[0001] The utility model relates to the technical field of salt production, in particular to a closed barrel. Background Art

[0002] In the process of industrial salt production, a mixing barrel is used to promote the mixing and homogenization of production raw materials. The mixing barrel consists of a barrel and an agitator, in which the agitator is installed on the transition rack directly above the barrel. The agitator evenly disperses the raw materials in the barrel through rotation and stirring, making the reaction more thorough.

[0003] During the stirring process, the barrel needs to be sealed to prevent external air from entering the barrel and affecting the smooth progress of the reaction; however, if the gas generated by the reaction cannot be discharged and accumulates in the barrel, it will cause an imbalance in the pressure inside and outside the barrel, which will also affect the smooth progress of the reaction. Therefore, it is necessary to provide a water seal device for the stirring barrel to improve the sealing and safety of the stirring barrel. The water seal device can prevent the gas generated in the barrel from entering but out.

[0004] However, the effect of the water seal device is also affected by the liquid level. If the liquid level is insufficient, the possibility of external gas entering the barrel will increase. Therefore, when using the water seal device, it is necessary to ensure that the water level is sufficient, and regularly check and replenish water in a timely and appropriate amount to maintain the good condition of the water seal device to ensure its normal operation, which will bring a workload to the staff. In view of this, we propose a closed barrel. Utility Model Content

Specifically, the plurality of air holes 12 are also conducive to the discharge of the gas generated in the barrel body 1 to the outside.

[0022] See also Figure 3 In the figure, the control mechanism includes an electric valve 18, a pressure sensor 15 and an L-shaped rod 14.

[0025] Working principle: the upper end of the agitator 7 is fixedly connected to the transition frame. When the agitator 7 is started, the agitator 7 stirs the raw materials in the barrel body 1, and the raw materials react fully to produce gas and escape from between the annular plate 1 2 and the annular plate 2 4. Since clean water is injected between the annular plate 1 2, the barrel body 1 and the connecting ring 2 13, and the liquid level is between the bottom end of the annular plate 2 4 and the upper end of the annular plate 1 2, the outside air will not enter the barrel body 1 to pollute the raw materials.

[0026] When the clean water between the annular plate 1 2, the barrel body 1 and the connecting ring 2 13 gradually evaporates and decreases, the annular floating plate 11 between the annular plate 1 2 and the annular plate 2 4 moves downward as the liquid level drops (in this process, three of the air holes 12 on the annular floating plate 11 will slide downward on the guide rods 19 on the corresponding connecting rings 2 13, preventing the annular floating plate 11 from rotating between the annular plate 1 2 and the annular plate 2 4), the annular floating plate 11 will drive the L-shaped rod 14 to move downward, and the L-shaped rod 14 will drive the push rod 16 to move downward until the bottom end of the push rod 16 contacts the contact point located below on the pressure sensor 15 (at this time, the liquid The surface height is close to and higher than the bottom end of the annular plate 2 4), the pressure sensor 15 is pressurized to generate a signal and transmit it to the electric valve 18 through the wire 17, so that the annular plate 2, the barrel 1 and the connecting ring 2 13 are replenished with water through the water replenishing pipe 9. As the liquid level rises, the top of the push rod 16 will contact the contact located above on the pressure sensor 15 (at this time the liquid level is close to the upper end of the annular plate 2), the pressure sensor 15 stops signal transmission, and the electric valve 18 is closed to stop replenishing water, thereby realizing timely and automatic water replenishment, which not only reduces the workload of the staff, but also improves the safety of production to a certain extent.
