[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] In one embodiment, see Figure 1 , Figure 2 and Figure 3, a mixing device for processing calcium hypochlorite, comprising a mixing tank 2 and a cover body 1, a hollow tube 7 is passed through the top of the cover body 1, the hollow tube 7 is rotatably connected to the top of the cover body 1, the lower end of the hollow tube 7 is closed, and the upper end of the hollow tube 7 is connected to an air intake mechanism 6, the air intake mechanism 6 is used to inject reaction gas into the hollow tube 7, a rotating mechanism 3 is provided inside the cover body 1, the rotating mechanism 3 is used to drive the hollow tube 7 to rotate, a plurality of branch pipes 8 are fixed to the outside of the hollow tube 7, the branch pipe 8 is communicated with the hollow tube 7, and the branch pipe 8 is open at one end away from the hollow tube 7, a stirring mechanism 4 is provided on the side of the hollow tube 7, the stirring mechanism 4 is used to stir the raw materials, an exhaust pipe 9 is connected to the side wall of the cover body 1, a filter screen plate 10 is provided below the exhaust pipe 9, the filter screen plate 10 is sleeved on the outside of the hollow tube 7, wherein the filter screen plate 10 is connected to a vibration mechanism 5, the vibration mechanism 5 is used to drive the filter screen plate 10 to vibrate up and down.

[0027] In this embodiment, when the equipment is processing calcium hypochlorite, the raw material for producing calcium hypochlorite (slaked lime) is directly poured into the mixing tank 2, and the cover 1 is covered to seal the mixing tank 2, and then the reaction gas (chlorine with a certain humidity) is injected into the hollow tube 7 through the air intake mechanism 6. Initially, the exhaust pipe 9 is in an open state. As the chlorine is filled, the original gas in the mixing tank 2 will be discharged from the exhaust pipe 9 until the mixing tank 2 is completely filled with chlorine. In order to avoid excessive chlorine from being discharged into the air through the exhaust pipe 9, the end of the exhaust pipe 9 can be directly inserted into the sodium hydroxide solution, and the tail gas is treated by the sodium hydroxide solution to avoid the chlorine from being discharged into the air. A filter screen 10 is provided under the exhaust pipe 9. The filter screen plate 10 can play a filtering role, thereby preventing the slaked lime powder from being discharged to the outside through the exhaust pipe 9 along with the air flow during the chlorine filling process, thereby avoiding the waste of slaked lime. The filter screen plate 10 is connected to a vibration mechanism 5, and the vibration mechanism 5 drives the filter to vibrate up and down, thereby shaking off the slaked lime powder at the bottom of the filter screen plate 10 into the mixing tank 2, which can effectively prevent the slaked lime powder from adhering to the bottom of the filter screen plate 10. After the chlorine filling is completed, the valve on the exhaust pipe 9 is closed to block the exhaust pipe 9. At this time, the slaked lime can be stirred by the stirring mechanism 4, so that the slaked lime can fully react with the chlorine, effectively improving the reaction efficiency and reaction effect of calcium hypochlorite and chlorine.

[0028] See also Figure 4 and Figure 6 The rotating mechanism 3 includes a motor 33 installed on the top of the cover body 1, the output end of the motor 33 passes through the top of the cover body 1 and is fixedly connected to the first gear 31, and the second gear 32 is fixed to the outside of the hollow tube 7, and the first gear 31 is meshed with the second gear 32;

[0029] When processing calcium hypochlorite, the motor 33 is started, and the motor 33 drives the first gear 31 to rotate, and the hollow tube 7 is driven to rotate through the meshing of the first gear 31 and the second gear 32, and then the branch pipe 8 on the side of the hollow tube 7 is driven to make a circular motion, so that after the chlorine enters the mixing tank 2, it can contact with the slaked lime at different positions, so that the reaction can be fully carried out, and the reaction efficiency and reaction effect are effectively improved.

[0030] See also Figure 5 The stirring mechanism 4 includes a connecting plate 41 fixed to the outside of the hollow tube 7, and a plurality of stirring rods 42 distributed in a circumference are penetrated inside the connecting plate 41. The upper end of the stirring rod 42 is connected to a rotation component, and the rotation component is used to drive the stirring rod 42 to rotate. The stirring rod 42 is fixed with a stirring blade 43 for stirring the raw materials outside.

[0031] When processing calcium hypochlorite, slaked lime is poured into the mixing tank 2 and covered with the cover body 1. During the covering process of the cover body 1, the stirring rod 42 and the stirring blade 43 will be immersed in the slaked lime inside the mixing tank 2. At this time, the hollow tube 7 can drive the stirring rod 42 to make a circular motion through the connecting plate 41 while rotating, thereby stirring the slaked lime inside the mixing tank 2, so that the reaction can be fully carried out, and while the stirring rod 42 is moving in a circular motion, the rotating assembly will also drive the stirring rod 42 to rotate, thereby further improving the stirring effect of the slaked lime.

[0032] See also Figure 5 The self-rotating assembly includes a third gear 44 fixed to the top of the stirring rod 42, and a gear ring 45 is fixed on the inner wall of the cover body 1, and the gear ring 45 is meshed with the third gear 44;

[0033] The connecting plate 41 drives the stirring rod 42 to move in a circular motion, and at the same time, the third gear 44 at the top of the stirring rod 42 also drives the third gear 44 to move in a circular motion. While the third gear 44 moves in a circular motion, it meshes with the gear ring 45. The meshing of the third gear 44 and the gear ring 45 drives the stirring rod 42 to rotate, thereby causing the stirring blade 43 to rotate, thereby improving the stirring effect of the slaked lime.

[0034] See also Figure 4 The vibration mechanism 5 includes a rod 53 fixedly connected to the top of the filter screen 10 and symmetrically distributed, a turntable 51 is fixed to the outside of the hollow tube 7, and a protrusion 52 symmetrically distributed and capable of squeezing the rod 53 is fixed to the bottom of the turntable 51, and an elastic component is connected to the top of the filter screen 10, and the elastic component is used for elastic support of the filter screen 10;

[0035] When processing calcium hypochlorite, the hollow tube 7 rotates while driving the turntable 51 to rotate. The turntable 51 drives the protrusion 52 at its bottom to make a circular motion. The protrusion 52 squeezes the push rod 53 while making a circular motion, so that the push rod 53 drives the filter screen plate 10 to move downward. When the protrusion 52 no longer squeezes the push rod 53, the filter screen plate 10 automatically moves upward under the action of the elastic component. This cycle is repeated, so that the filter screen plate 10 can continuously vibrate up and down, thereby preventing the slaked lime powder from adhering to the bottom of the filter screen plate 10.

[0036] See also Figure 4 The elastic component includes a limit rod 57 which is fixedly connected to the top of the cover body 1 and is symmetrically distributed. The limit rod 57 passes through the filter screen plate 10 and is slidably connected to the filter screen plate 10. A spring 56 is provided outside the limit rod 57. Both ends of the spring 56 are respectively fixedly connected to the top of the cover body 1 and the top of the filter screen plate 10;

[0037] The filter screen plate 10 is elastically supported by the spring 56 so that the filter screen plate 10 can be reset, wherein the limiting rod 57 can limit the filter screen plate 10, thereby effectively improving the stability of the filter screen plate 10 when it moves up and down.

[0038] See also Figure 4 The outer part of the hollow tube 7 is provided with a limiting ring 54, which penetrates the filter screen plate 10 and is fixedly connected to the inner wall of the cover body 1 through a fixing plate 55, wherein the filter screen plate 10 is slidably connected to the outer wall of the limiting ring 54, and the hollow tube 7 is rotatably connected to the inner wall of the limiting ring 54;

[0039] The filter screen plate 10 is supported and limited by the limiting ring 54, which can effectively improve the stability of the filter screen plate 10 when it moves up and down.

[0040] See also Figure 6 The air intake mechanism 6 includes a support frame 64 fixed to the top of the cover body 1, a guide pipe 63 is passed through the support frame 64, and the guide pipe 63 is fixedly connected to the support frame 64, wherein the lower end of the guide pipe 63 passes through the top of the hollow tube 7 and is rotatably connected to the top of the hollow tube 7, and the upper end of the guide pipe 63 is connected to the first air intake pipe 61 and the second air intake pipe 62;

[0041] When processing calcium hypochlorite, chlorine is first filled into the flow pipe 63 through the first air inlet pipe 61. During this process, the valve on the second air inlet pipe 62 is closed and the exhaust pipe 9 is opened. After the chlorine is filled, the valves on the first air inlet pipe 61 and the exhaust pipe 9 are closed. When the production of calcium hypochlorite is completed, the valves on the second air inlet pipe 62 and the exhaust pipe 9 are opened, and air is filled into the flow pipe 63 through the second air inlet pipe 62 until the mixing tank 2 is completely filled with air. During this process, the chlorine that has not fully reacted in the mixing tank 2 will be discharged to the outside through the exhaust pipe 9 and absorbed by the sodium hydroxide solution, which can effectively avoid the phenomenon that the chlorine that has not fully reacted is directly discharged into the air when the cover body 1 is separated from the mixing tank 2.

[0042] See also Figure 3 and Figure 6 A return pipe 66 is connected above the filter screen plate 10 and on the side wall of the cover body 1, and the other end of the return pipe 66 is connected to the guide pipe 63;

[0043] When calcium hypochlorite is processed, the booster valve on the reflux pipe 66 is opened. Under the action of the booster valve, the chlorine gas inside the cover body 1 will enter the inside of the guide pipe 63 again through the reflux pipe 66, and be discharged from the opening at the end of the branch pipe 8 through the hollow pipe 7, so that the chlorine gas can circulate inside the mixing tank 2. At the same time, with the circular motion of the branch pipe 8, the chlorine gas can be further fully contacted with the slaked lime, further improving the reaction efficiency.

[0044] See also Figure 6 A cooling box 65 is installed on the top of the cover body 1, and a return pipe 66 passes through the inside of the cooling box 65;

[0045] The cooling box 65 can cool the chlorine gas in the reflux pipe 66, thereby reducing the temperature of the chlorine gas entering the mixing tank 2, thereby cooling the interior of the mixing tank 2, avoiding the generation of a large amount of by-products due to temperature increase, and increasing the production of calcium hypochlorite.

[0046] Working principle: When the equipment is processing calcium hypochlorite, the raw material for producing calcium hypochlorite (slaked lime) is directly poured into the mixing tank 2, and the cover 1 is covered to seal the mixing tank 2, and then chlorine is filled into the guide pipe 63 through the first air inlet pipe 61. During this process, the valve on the second air inlet pipe 62 is closed and the exhaust pipe 9 is opened. In order to avoid excessive chlorine being discharged into the air through the exhaust pipe 9, the end of the exhaust pipe 9 can be directly inserted into the sodium hydroxide solution, and the tail gas is treated by the sodium hydroxide solution to avoid chlorine being discharged into the air. A filter screen 10 is provided under the exhaust pipe 9, and the filter screen 10 can play a filtering role to avoid slaked lime powder being accompanied by the chlorine during the chlorine filling process. The phenomenon that the airflow is discharged to the outside through the exhaust pipe 9 avoids the waste of slaked lime. When the chlorine is filled, the valves on the first air inlet pipe 61 and the exhaust pipe 9 are closed, and the motor 33 is started at this time. The motor 33 drives the first gear 31 to rotate, and the hollow tube 7 is driven to rotate through the meshing of the first gear 31 and the second gear 32, and then the branch pipe 8 on the side of the hollow tube 7 is driven to make a circular motion, so that after the chlorine enters the mixing tank 2, it can contact the slaked lime at different positions. When the hollow tube 7 rotates, it also drives the stirring rod 42 to make a circular motion through the connecting plate 41. When the connecting plate 41 drives the stirring rod 42 to move in a circular motion, it also drives the third gear 44 on the top of the stirring rod 42 to move in a circular motion. The third gear 44 moves in a circular motion. When the third gear 44 and the gear ring 45 are engaged, the stirring rod 42 is driven to rotate, so that the stirring blade 43 can rotate while performing a circular motion, thereby effectively improving the stirring effect of the slaked lime. In addition, the hollow tube 7 also drives the turntable 51 to rotate while rotating, and the turntable 51 drives the protrusion 52 at its bottom to perform a circular motion. The protrusion 52 squeezes the push rod 53 while performing a circular motion, so that the push rod 53 drives the filter screen plate 10 to move downward. When the protrusion 52 no longer squeezes the push rod 53, the filter screen plate 10 automatically moves upward under the action of the spring 56. This cycle is repeated, so that the filter screen plate 10 can continuously vibrate up and down, thereby preventing the slaked lime powder from adhering to the bottom of the filter screen plate 10. The phenomenon of the part is avoided, and the waste of slaked lime is avoided. When processing calcium hypochlorite, the booster valve on the reflux pipe 66 can also be opened. Under the action of the booster valve, the chlorine gas inside the cover body 1 will enter the inside of the guide pipe 63 again through the reflux pipe 66, and be discharged from the opening at the end of the branch pipe 8 through the hollow pipe 7, so that the chlorine gas can circulate in the mixing tank 2. At the same time, with the circular motion of the branch pipe 8, the chlorine gas can be further fully contacted with the slaked lime, and the reaction efficiency is further improved. At the same time, the cooling box 65 can cool the chlorine gas inside the reflux pipe 66, thereby playing a cooling role in the mixing tank 2, avoiding the phenomenon of a large number of by-products caused by temperature increase, and improving the production of calcium hypochlorite.
