Description

Technical Field

[0001] This utility model relates to the field of color bleach powder production and preparation technology, specifically to an oxidation reaction device for color bleach powder production. Background Technology

[0002] Color-safe bleach powder is a highly efficient oxygen-based bleaching detergent. Its main component is sodium percarbonate, which dissolves in water to generate hydrogen peroxide. This hydrogen peroxide then reacts chemically to produce nascent oxygen, which destroys the pigments in the stains, thus achieving the effects of stain removal and bleaching.

[0003] In the production of color-safe bleach, various raw materials and reaction additives need to be placed in a reactor for reaction. Initially, the materials in the reactor need to be heated to promote dynamic fusion between molecules. Heating is stopped once the materials begin to react, as the various material elements automatically generate heat during the fusion process (thermal reaction). Although the temperature rise is not very high, sustained high temperatures can damage and reduce some of the active molecules in the materials, directly affecting the final performance of the bleaching powder. Current solutions mainly involve cooling with cooling pipes. However, due to the long length of the cooling pipes surrounding the reactor, uneven heat exchange and temperature drop are prone to occur during cooling. Furthermore, the initial section of the pipes is prone to wrinkles and creases in the fluid material due to excessively rapid cooling. This makes temperature control inconvenient and hinders proper temperature balance within the reactor.

[0004] Therefore, this utility model provides an oxidation reaction device for the production of color bleach powder to solve the above-mentioned problems. Utility Model Content

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

Please refer to [link / reference]. Figures 1-3 An oxidation reaction apparatus for producing color bleach powder according to this embodiment includes a temperature control cylinder 100, a reaction vessel 200 coaxially fixed inside the temperature control cylinder 100, a material stirring assembly 300 inside the reaction vessel 200, a circumferential flow guide cavity 1001 between the inner radial ring and bottom of the temperature control cylinder 100 and the reaction vessel 200, a heating component 400 and a cooling component 410 for heating and cooling the liquid medium in the circumferential flow guide cavity 1001 respectively provided at the bottom of the temperature control cylinder 100, and a water temperature mixing assembly 500 for mixing the liquid medium in the circumferential flow guide cavity 1001 also provided at the bottom of the temperature control cylinder 100.

[0024] The material stirring assembly 300 includes a main shaft 310 coaxially and vertically rotatably mounted on the upper inner side of the reactor 200, spiral blades 320 arranged along the outer periphery and height of the main shaft 310, multiple stirring paddles 330 arranged along the height of the main shaft 310, and a motor 340 fixed to the top of the reactor 200 for driving the main shaft 310 to rotate axially. In use, the motor 340 drives the main shaft 310, spiral blades 320, and stirring paddles 330 to rotate synchronously. The spiral blades 320 continuously lift the material at the bottom of the reactor 200 upwards, creating alternating mixing with the upper material. Simultaneously, the rotating stirring paddles 330 forcefully stir and fuse the alternating vertical and radial flow of the material. This combined action not only improves the material fusion efficiency but also ensures even temperature distribution. The heating element 400 uses a resistance wire heating plate, and the cooling element 410 uses a semiconductor cooling chip, with the cooling surface of the semiconductor cooling chip facing the circumferential flow guide cavity 1001. It is understood that the resistance wire heating plate and the semiconductor cooling chip have excellent unit heating / cooling efficiency, enabling rapid heating and cooling of the water in the circumferential flow guide cavity 1001. The water temperature mixing assembly 500 includes a shaft 510 coaxially and vertically rotatably mounted at the bottom of the temperature regulating cylinder 100, a waterproof sealing shaft 520 located at the connection between the shaft 510 and the temperature regulating cylinder 100, a motor 530 located at the bottom outer side of the temperature regulating cylinder 100 for driving the shaft 510 to rotate axially, and multiple stirring blades 540 fixed to the outer wall of the shaft 510. Specifically, in this embodiment, when it is necessary to cool down the reactor 200 and the materials inside, the cooling component 410 is activated to rapidly cool the water in the circumferential guide cavity 1001. At the same time, the water temperature mixing component 500 can continuously agitate the water in the guide cavity, so that the water temperature can be reduced linearly and evenly. Under this all-round water bath contact, the reactor 200 and the materials inside are also cooled evenly and linearly. At the same time, with the multiple cooperation of the material stirring component 300, the defects such as wrinkles and claw marks caused by uneven temperature drop in traditional methods are effectively avoided.

[0025] Preferably, the outer periphery of the temperature regulating cylinder 100 is further covered with a heat insulation layer 110, and the top of the temperature regulating cylinder 100 is respectively equipped with temperature sensors 600 corresponding to the circumferential flow guide cavity 1001 and the inner cavity of the reaction vessel 200; the oxidation reaction device is also equipped with a PLC controller. It can be understood that the heat insulation layer 110 can prevent the external temperature from interfering with the water temperature in the circumferential flow guide cavity 1001. In addition, the temperature sensors 600 can monitor the water temperature in the circumferential flow guide cavity 1001 and the temperature of the material in the reaction vessel 200 in real time. The control system will accurately adjust the output power and time of the cooling components 410, etc., according to the temperature changes between the two, making the operation more reasonable.

[0026] Preferably, a water injection valve 120 connected to the circumferential flow guide cavity 1001 is provided on the upper outer side of the temperature regulating cylinder 100, and a drain valve 130 connected to the circumferential flow guide cavity 1001 is provided on the lower outer side of the temperature regulating cylinder 100. It can be understood that liquid medium can be injected into the circumferential flow guide cavity 1001 by opening the water injection valve 120, and water in the flow guide cavity can be discharged by opening the drain valve 130. Furthermore, a feeding port and a corresponding conveying valve cover 210 are provided on one side of the top of the reaction vessel 200, and a discharge valve 220 is provided on one side of the bottom of the reaction vessel 200, extending through the outer side of the temperature regulating cylinder 100. The main and auxiliary materials of color bleach powder can be added to the reaction vessel 200 by opening the conveying valve cover 210, and after the materials have completed the fusion reaction, the materials are discharged by opening the discharge valve 220.

[0027] In summary, the oxidation reaction apparatus for producing color bleach powder according to this embodiment, when it is necessary to cool down the reaction vessel 200 and the materials inside, activates the cooling component 410 to rapidly cool the water in the circumferential guide cavity 1001. At the same time, the water temperature mixing component 500 can continuously agitate the water in the guide cavity, so that the water temperature can be reduced linearly and evenly. Under this all-round water bath contact, the reaction vessel 200 and the materials inside are also cooled evenly and linearly. At the same time, with the multiple coordination of the material stirring component 300, the formation of wrinkles and chicken claw marks on the material caused by uneven temperature drop in the traditional method is effectively avoided, and the temperature of the material inside the vessel is well controlled and balanced.
