Description

Technical Field

[0001] This application belongs to the field of daily chemical production equipment technology, specifically relating to a boiler used for heating and preventing oxidation of hair dye cream. Background Technology

[0002] In existing technologies, precise temperature control and oxidation prevention are key factors in ensuring product quality and stability during the production of hair dye cream. The chemical components in hair dye cream are easily affected by oxidation during heating, leading to problems such as product deterioration, inaccurate color, or abnormal chemical reactions. Therefore, the heating equipment not only needs to provide a stable heat source but must also effectively prevent oxygen or air from entering the reaction vessel to ensure the production quality of the hair dye cream.

[0003] In existing technologies, common heating methods include direct steam heating and jacketed heating. Direct steam heating involves directly introducing steam into the reactor, which, while having high heat transfer efficiency, carries the risk of oxygen or air entering the reactor with the steam, potentially causing oxidation of the hair dye. Jacketed heating, on the other hand, involves installing a jacket around the reactor and indirectly heating the hair dye inside by introducing steam or a heat-conducting liquid through the jacket. While this reduces oxygen contamination to some extent, its heat transfer efficiency is relatively low, and it cannot completely prevent air from entering through the gaps between the jacket and the reactor.

[0004] Furthermore, some existing heating equipment lacks adequate consideration for sealing in its design, or its sealing performance deteriorates after long-term use, allowing air to easily enter the reactor. This not only affects the quality of the hair dye cream but may also increase energy consumption and costs during production, reducing production efficiency and economic benefits.

[0005] Therefore, in order to solve the problem of oxygen or air entering the reaction vessel during the production of hair dye cream, there is an urgent need for a boiler for heating and preventing oxidation of hair dye cream, so as to improve the production quality and process stability of hair dye cream. Utility Model Content

[0006] This application aims to address the technical problem in the existing technology that requires precise temperature control and prevention of oxidation of reactants during the production of hair dye cream. The latter is a difficult point in the production process of hair dye cream. In actual production, external oxygen will enter the reaction vessel through the gaps and accelerate the oxidation of reactants as stirring proceeds, reducing the finished product quality and process stability of hair dye cream. The application proposes a boiler for heating and preventing oxidation of hair dye cream.

[0007] This application adopts the following scheme: a boiler for heating and preventing oxidation of hair dye cream, including a reaction vessel, a stirring assembly rotatably disposed on the reaction vessel, an aeration assembly disposed at the bottom of the reaction vessel, a nitrogen supply assembly disposed on the aeration assembly, and a reflux assembly disposed on the reaction vessel. The nitrogen supply assembly is used to supply nitrogen to the aeration assembly, the aeration assembly is used to disperse the nitrogen into micro-nano bubbles and transport them into the reaction vessel, and the reflux assembly is used to collect excess nitrogen in the reaction vessel and return it to the reaction vessel.

The temperature sensor is used to sense the temperature of the nitrogen in the first gas storage tank. When the temperature value sensed by the temperature sensor reaches a preset value, the nitrogen in the first gas storage tank will be transported to the aeration assembly.

[0011] In some feasible embodiments, the reflux assembly includes a reflux gas outlet located on the top of the reactor, a reflux gas inlet located on the side wall of the reactor, and a reflux tank assembly located between the reflux gas outlet and the reflux gas inlet. Excess nitrogen gas in the reactor is discharged from the reactor through the reflux gas outlet, flows through the reflux tank assembly, and then enters the reactor through the reflux gas inlet.

[0012] In some feasible embodiments, the reflux tank assembly includes a second gas storage tank disposed on the reflux gas outlet, and an adsorption tank disposed on the second gas storage tank, the adsorption tank being used to adsorb impurities in nitrogen gas.

[0013] In some feasible embodiments, a second heating coil is provided on the inner wall of the second gas storage tank, and the second heating coil is used to heat the nitrogen gas in the second gas storage tank.

[0014] In some feasible embodiments, the adsorption tank is provided with an adsorption element, which includes a first adsorption layer, a second adsorption layer and a third adsorption layer arranged sequentially along the gas conveying direction. The thickness of the third adsorption layer is greater than the thickness of the first adsorption layer and the thickness of the third adsorption layer is greater than the thickness of the second adsorption layer.

[0020] This application provides a boiler for heating and preventing oxidation of hair dye cream, comprising a reaction vessel, a rotating stirring assembly on the reaction vessel, an aeration assembly at the bottom of the reaction vessel, a nitrogen supply assembly on the aeration assembly, and a reflux assembly on the reaction vessel. The nitrogen supply assembly supplies nitrogen to the aeration assembly, which disperses the nitrogen into micro- and nano-bubbles and delivers it into the reaction vessel.

[0023] This application provides a boiler for heating and preventing oxidation of hair dye cream, comprising a reaction vessel, a rotating stirring assembly on the reaction vessel, an aeration assembly at the bottom of the reaction vessel, a nitrogen supply assembly on the aeration assembly, and a reflux assembly on the reaction vessel. The nitrogen supply assembly supplies nitrogen to the aeration assembly, which disperses the nitrogen into micro- and nano-bubbles and delivers it into the reaction vessel. The reflux assembly collects excess nitrogen in the reaction vessel and returns it back to the reaction vessel. By dispersing nitrogen into micro- and nano-bubbles through the aeration assembly before entering the reaction vessel, oxygen in the reaction vessel is effectively discharged, preventing the hair dye cream from oxidizing. The combination of the stirring assembly and the aeration assembly ensures thorough mixing of nitrogen and hair dye cream, enhancing the anti-oxidation effect. This method has the advantages of simple structure, easy operation, high raw material utilization, low implementation cost, effective improvement of product quality, and ease of promotion and implementation.

[0024] In this embodiment, the nitrogen supply component 4 includes a liquid nitrogen tank 40 and a first gas storage tank 41 disposed on the liquid nitrogen tank 40. The first gas storage tank 41 is used to store gaseous nitrogen.

[0025] In this embodiment, the nitrogen supply component 4 also includes a first heating coil 42 disposed between the liquid nitrogen tank 40 and the first gas storage tank 41. The first heating coil 42 is used to heat the liquid nitrogen output from the liquid nitrogen tank 40 to a preset temperature.

[0026] In actual implementation, liquid nitrogen tank 40 stores liquid nitrogen as a nitrogen supply source. When nitrogen needs to be supplied to the reactor, liquid nitrogen is output from liquid nitrogen tank 40. The output liquid nitrogen is heated to a preset temperature by the first heating coil 42 and converted into high-temperature gaseous nitrogen to heat the reactants in the reactor.

[0027] In actual implementation, the main function of the first gas storage tank 41 is to store a certain amount of gaseous nitrogen for a stable subsequent supply to the aeration components. This helps maintain the stability of the nitrogen supply pressure and flow rate in the entire system, ensures that the nitrogen is fully heated, and plays a certain buffering role, reducing the instantaneous load on the pipeline.

[0028] In actual implementation, nitrogen stored in the first gas storage tank 41 is transported to the aeration component according to production needs. The aeration component disperses the nitrogen into micro-nano bubbles and then transports them into the reaction vessel to achieve anti-oxidation protection during the heating process of the hair dye cream. The high-temperature nitrogen micro-nano bubbles can simultaneously heat and remove oxygen, effectively simplifying the reaction device.

[0029] In actual implementation, an insulation layer is also provided on the outer wall of the first gas storage tank to prevent the loss of nitrogen heat inside the first gas storage tank.

[0030] In this embodiment, the nitrogen supply component 4 also includes a temperature sensor 43 disposed on the first gas storage tank 41. The temperature sensor 43 is used to sense the temperature of the nitrogen in the first gas storage tank 41. When the temperature value sensed by the temperature sensor 43 reaches a preset value, the nitrogen in the first gas storage tank 41 will be transported to the aeration component 3.

[0033] In actual implementation, by setting up a reflux pipe group, excess nitrogen in reactor 1 can be effectively collected and treated, avoiding nitrogen waste. At the same time, by adsorbing impurities, the quality of the refluxed nitrogen is ensured, maintaining the stability of the nitrogen environment in reactor 1, preventing the oxidation of raw materials in the reactor, and improving product quality and process stability.

[0034] In this embodiment, a second heating coil 522 is provided on the inner wall of the second gas storage tank 520. The second heating coil 522 is used to heat the nitrogen gas in the second gas storage tank 520.

[0035] In actual implementation, the second heating coil can dry excess nitrogen gas and remove moisture from it.

[0036] In this embodiment, the adsorption tank 521 is provided with an adsorption element 6. The adsorption element 6 includes a first adsorption layer 60, a second adsorption layer 61 and a third adsorption layer 62 arranged sequentially along the gas conveying direction. The thickness of the third adsorption layer 62 is greater than the thickness of the first adsorption layer 60 and the thickness of the third adsorption layer 62 is greater than the thickness of the second adsorption layer 61.

[0037] In this embodiment, the material of the first adsorption layer 60 is selected as iron oxide powder or iron oxide powder;

[0038] The material of the second adsorption layer 61 is selected from sodium hydroxide particles or calcium hydroxide particles;

[0039] The third adsorption layer 62 is made of activated carbon.

[0040] In actual implementation, by selecting the materials of the first adsorption layer, the second adsorption layer, and the third adsorption layer respectively, oxygen, carbon dioxide, water vapor, and organic gases in nitrogen can be effectively removed, and the reactants in the reactor can be prevented from being oxidized by gaseous impurities.

[0041] In this embodiment, the stirring assembly 2 includes a drive motor, a stirring rod 20 disposed on the output end of the drive motor, and a stirring blade 21 disposed on the end of the stirring rod 20.
