[0036] Further, a preferred embodiment of the utility model, the air release control device includes U type board 13, the bottom of U type board 13 is fixed with two symmetrical exhaust adjustment pipe 14, the exhaust adjustment pipe 14 is made of corrosion-resistant titanium alloy.

[0037] Further, a preferred embodiment of the utility model, the exhaust adjustment pipe 14 is inserted through the air release pipe 8, and T type gas plugging rod 12 is located inside the exhaust adjustment pipe 14.

[0038] Further, a preferred embodiment of the utility model, the exhaust adjustment pipe 14 is provided with a plurality of exhaust holes 15 from small to large longitudinal order, and the plurality of exhaust holes 15 are aligned with the air release hole 9 of the air release pipe 8 side.

[0039] Further, a preferred embodiment of the utility model, the bottom of U type board 13 is provided with the first trapezoidal drive block 16, and the slope of the first trapezoidal drive block 16 is downward.

[0040] Further, a preferred embodiment of the utility model, the slope of the first trapezoidal drive block 16 and the slope of the second trapezoidal drive block 17 are in contact with each other, and the slope of the second trapezoidal drive block 17 is upward.

[0041] Further, a preferred embodiment of the utility model, second trapezoidal drive block 17 side be connected with two air cylinders 18, air cylinder 18 is fixed on kettle cover 2.

[0042] The working process of the utility model is as follows:

[0043] When starting to prepare bleaching powder concentrate, open the sealing cover 7, add calcium hydroxide reaction components into the feed inlet 6, then according to the preparation demand of main reaction, pass the required amount of chlorine gas into the air inlet 10, so that calcium hydroxide and chlorine gas enter the inside of the main reaction kettle body 1 and mix to generate calcium hypochlorite, which is the main component of bleaching powder concentrate. During the reaction process, the speed reducer motor 4 is started to run, the output end of the speed reducer motor 4 drives the stirring rod 3 to rotate, the stirring rod 3 drives the several stirring blades 5 of the rod body to rotate synchronously in the main reaction kettle body 1, so that the stirring and mixing of calcium hydroxide and chlorine gas in the main reaction kettle body 1 can be fully realized, and the stirring rod 3 and the stirring blade 5 can switch the uniform speed or variable speed mode according to the control speed of the speed reducer motor 4, so that the calcium hydroxide and chlorine gas can be fully mixed and reacted, the preparation purity and concentration of calcium hypochlorite are improved; The traditional main reaction equipment needs manual stirring in the main reaction process, and the uniform arrangement of the several stirring blades improves the phenomenon that the single stirring blade stirring is insufficient and the reaction mixing is poor, and optimizes the main reaction preparation quality of bleaching powder concentrate.

[0044] During the process of mixing and reacting of calcium hydroxide and chlorine gas in the main reactor 1, due to the influence of internal humidity or high temperature and other environmental factors, side reactions may occur to produce excess chlorine or oxygen, causing gas to escape. Since the main reactor 1 is in a fully closed state, the excess escaping gas can easily cause the internal pressure of the main reactor 1 to increase sharply and even explode. Therefore, when the bleaching powder occurs side reactions to cause excess gas to escape, the pressure index inside the main reactor is detected by the pressure sensor, and if the pressure index is greater than the preset threshold, then the two air cylinders 18 are controlled to push forward at the same time, thereby driving the second trapezoidal drive block 17 to translate forward synchronously. At this time, the second trapezoidal drive block 17 pushes on the slope of the first trapezoidal drive block 16 during translation, so that the second trapezoidal drive block 17 drives the first trapezoidal drive block 16 to rise upward continuously. In this way, the U-shaped plate 13 drives the two end exhaust adjusting pipes 14 to move upward gradually in the exhaust pipe 8. When the exhaust adjusting pipe 14 rises to a certain height, the smallest exhaust hole 15 reaches and aligns with the exhaust hole 9 on the side of the exhaust pipe 8, and at this time the excess chlorine or oxygen escaping from the main reactor 1 can be discharged through the exhaust hole 15, then collected to the storage device through the gas pipeline connected to the exhaust hole 9 for centralized treatment. If the pressure of the escaping gas is too large, the two air cylinders 18 will continue to advance, thereby repeating the above steps to drive the exhaust adjusting pipe 14 to continue to rise. According to the gas pressure value, the corresponding size of the exhaust hole 15 on the exhaust adjusting pipe 14 is adjusted to align with the exhaust hole 9 to discharge the pressure relief in different amounts, achieving a precise and stable gas escape pressure relief effect, which can ensure the safety of the preparation of bleaching powder during the main reaction process, reduce the risk coefficient of reaction explosion, protect the balance and rationality of the internal reaction environment, avoid the phenomenon of excessive crystalline particle agglomeration of the prepared bleaching powder due to high temperature and other factors, and has high reliability. In addition, the T-shaped gas blocking rod 12 can isolate the communication and discharge of the current exhaust hole 9 and the previous one or more exhaust holes 15 during the rising and adjusting process of the exhaust adjusting pipe 14, achieving a quantitative specification of pressure relief discharge effect, preventing excessive discharge from causing pollution to the surrounding environment or harming human health due to chlorine gas.
