DETAILED DESCRIPTION

[0031] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0032] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of particular examples in the following description are depicted. Of course, they are merely examples and are not intended to limit the present application. Furthermore, the present application can repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not indicate a relationship between the various embodiments and / or settings discussed.

[0033] For the purpose of description, spatial relative terms can be used in the description to describe the relative position relationship or movement of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is flipped over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the description are interpreted accordingly.

[0034] In order to solve the technical problems in the prior art, the present application provides a material reaction system with a heat preservation structure, which can realize the injection of water meeting the required reaction temperature into the heat preservation cavity through the cooperation of the liquid supply module and the heat exchanger by arranging a heat preservation layer between the inner wall and the outer wall of the reaction kettle, so as to facilitate the sufficient reaction of the material located at the inner wall and improve the overall reaction efficiency.

[0035] Figures 1-8The material reaction system with heat preservation structure provided by the embodiment of the application comprises a first material stirring kettle 1, a second material stirring kettle 2, a reaction kettle 3, an emulsifying device 4 and a finished product kettle 5. The first material stirring kettle 1 and the second material stirring kettle 2 are connected with the reaction kettle 3 respectively, the reaction kettle 3 and the emulsifying device 4 are connected with the finished product kettle 5 respectively. The first material stirring kettle 1 contains the first material and stirs the first material during work. The second material stirring kettle 2 contains the second material and stirs the second material during work. The reaction kettle 3 stirs and reacts the first material injected from the first material stirring kettle 1 and the second material injected from the second material stirring kettle 2 during work to form the first intermediate product. The emulsifying device 4 contains the third material and stirs and emulsifies the third material during work to form the second intermediate product. The finished product kettle 5 contains the fourth material and stirs and reacts the first intermediate product, the second intermediate product and the fourth material injected during work to form the final product. The first material stirring kettle 1, the second material stirring kettle 2, the emulsifying device 4 and the finished product kettle 5 can be fed respectively, so that the first material is prevented from mixing and reacting in advance, a large amount of gas is prevented from being generated to cause the gas pressure to increase and a safety hazard is prevented from being caused, a safe and efficient production system is provided for brine reaction, and the final product is discharged through the discharge port of the finished product kettle 5.

[0036] Please refer to Figure 2 The reaction kettle 3 is provided with a gas pressure sensor 6 and a suction mechanism 7. The gas pressure sensor 6 is used for detecting the gas pressure in the reaction kettle 3. The suction mechanism 7 is connected with the reaction kettle 3. The gas pressure sensor 6 is provided with a gas pressure threshold value. The gas pressure sensor 6 obtains the gas pressure value in the reaction kettle 3 and compares the gas pressure value with the gas pressure threshold value. When the gas pressure value is greater than the gas pressure threshold value, the gas pressure sensor 6 controls the suction mechanism 7 to perform the gas suction work on the inside of the reaction kettle 3. The gas pressure sensor 6 and the suction mechanism 7 can control the gas pressure in the reaction kettle 3 in real time, avoid the case that the gas pressure in the reaction kettle 3 is too high and the furnace is exploded, and improve the safety factor. At the same time, the gas pressure is maintained in the preset range to promote the full reaction of the material and reduce the generation of more foam. Preferably, the suction mechanism 7 is a gas suction pump structure, but is not limited to this, and other structures for gas suction can also be adopted. Further preferably, the suction mechanism 7 is connected with the top of the reaction kettle 3. In this way, when the suction mechanism 7 performs the gas suction work, it has a large probability to suck away the gas in the reaction kettle 3 instead of the liquid such as the material, so that the pressure is effectively reduced, and the waste of the material is avoided due to the large amount of liquid sucked away.

[0037] Please continue to refer to Figure 2The material reaction system with the heat preservation structure of the present application further comprises a liquid recovery mechanism 8 connected with the suction mechanism 7 for recovering the liquid small molecules sucked out with the gas. By arranging the liquid recovery mechanism 8, the liquid small molecules sucked out by the suction mechanism 7 can flow back into the reaction kettle 3, thus avoiding the waste caused by the loss of the material and improving the use efficiency of the material. Further, the liquid recovery mechanism 8 comprises a condensing structure 9 connected with the suction mechanism 7, one end of a liquid backflow pipeline 10 and one end of a gas recovery pipeline 11, the other end of the liquid backflow pipeline 10 is connected with the reaction kettle 3. The liquid small molecules are condensed into larger liquid beads by the condensing structure 9 and flow back into the reaction kettle 3 through the liquid backflow pipeline 10, and the gas is transmitted to the treatment device outside through the gas recovery pipeline 11.

[0038] Please continue to refer to Figure 3 The material reaction system with the heat preservation structure of the present application further comprises a cleaning module 12 connected with the reaction kettle 3 for supplying high-pressure water or high-pressure gas into the reaction kettle 3 and discharging to clean the reaction kettle 3. The arrangement of the cleaning module 12 realizes high-intensity flushing inside the reaction kettle 3 to flush out the condensed and precipitated brine and other impurities, thus achieving the cleaning of the reaction kettle 3. Further, the cleaning module 12 comprises a waterway cleaning module 13 and a gasway cleaning module 14, the waterway cleaning module 13 and the gasway cleaning module 14 are respectively connected with the reaction kettle 3, the waterway cleaning module 13 is used for supplying high-pressure water into the reaction kettle 3 and discharging to clean the reaction kettle 3, and the gasway cleaning module 14 is used for supplying high-pressure gas into the reaction kettle 3 and discharging to clean the reaction kettle 3. It can be understood that the gas and water supplied by the cleaning module 12 are food-grade.

[0039] Please refer to Figure 4 The cleaning module 12 comprises a cleaning inlet 15 and a cleaning outlet 16, the cleaning inlet 15 is connected at the top end of the reaction kettle 3, and the cleaning outlet 16 is connected at the bottom end of the reaction kettle 3. The cleaning inlet 15 arranged at the top end of the reaction kettle 3 can make the high-pressure gas or high-pressure water enter smoothly without being easily blocked by the material, and also avoids the possibility of material backflow and damage to the cleaning module 12. The waterway cleaning module 13 comprises a water supply module 17 and a liquid recovery module 18, the water supply module 17 is connected with the cleaning inlet 15, and the liquid recovery module 18 is connected with the cleaning outlet 16. The gasway cleaning module 14 comprises a gas supply module 19 and a gas recovery module 20, the gas supply module 19 is connected with the cleaning inlet 15, and the gas recovery module 20 is connected with the cleaning outlet 16. That is, the waterway cleaning module 13 and the gasway cleaning module 14 share the cleaning inlet 15 and the cleaning outlet 16, thus avoiding the possibility of leakage of the reaction kettle 3 caused by the arrangement of too many pipelines.

[0040] Please refer to Figures 5-7 A heat preservation layer 21 is arranged between the inner wall and the outer wall of the reaction kettle 3, and a heat preservation cavity is arranged in the heat preservation layer 21. The heat preservation cavity is connected with a heat exchanger 23, the heat exchanger 23 is connected with a liquid supply module 24, the liquid supply module 24 is used to provide low-temperature water and / or high-temperature water to the heat exchanger 23, and the heat exchanger 23 is used to inject the low-temperature water or the high-temperature water provided by the liquid supply module 24 into the heat preservation cavity, or is used to inject the low-temperature water and the high-temperature water mixed and heat-exchanged into the heat preservation cavity, so that the injected water meets the reaction temperature of the material at the inner wall of the reaction kettle 3, and the reaction efficiency is improved. Specifically, the liquid supply module 24 includes a low-temperature liquid module 30 and a high-temperature liquid module 31, and the low-temperature liquid module 30 and the high-temperature liquid module 31 are respectively connected with the heat exchanger 23. The low-temperature liquid module 30 is used to provide low-temperature liquid, and the high-temperature liquid module 31 is used to provide high-temperature liquid. By providing high-temperature liquid or low-temperature liquid or mixing the two to provide for the heat preservation cavity, it is avoided that only providing high-temperature liquid or low-temperature liquid causes that the temperature demand of the material at the inner wall of the reaction kettle 3 cannot be met. By arranging the heat preservation layer 21 between the inner wall and the outer wall of the reaction kettle 3, and by cooperating the liquid supply module 24 with the heat exchanger 23 to inject water meeting the required temperature of the reaction into the heat preservation cavity, it is beneficial to promote that the material located at the inner wall can fully react, and it is beneficial to improve the overall reaction efficiency.

[0041] Please refer to Figure 8 A longitudinal stirring pipe 25, a ring-shaped stirring pipe 26, a bottom scraping structure 27 and a shearing structure 28 in the shape of an overall "eye" are arranged in the reaction kettle 3. The longitudinal stirring pipe 25 is arranged along the axial direction of the reaction kettle 3. The ring-shaped stirring pipe 26 is connected to the bottom of the longitudinal stirring pipe 25. The bottom scraping structure 27 is arranged at the bottom of the longitudinal stirring pipe 25 and is connected with the ring-shaped stirring pipe 26. The shearing structure 28 is connected to the side of the longitudinal stirring pipe 25. The ring-shaped stirring pipe 26 is used to drive the bottom scraping structure 27 to rotate while providing a certain stirring function. The bottom scraping structure 27 is used to scrape off the material adhered to the bottom of the reaction kettle 3 when the longitudinal stirring pipe 25 moves. The shearing structure 28 is used to shear the large block of material when the longitudinal stirring pipe 25 moves. By arranging the longitudinal stirring pipe 25, the reaction rate is accelerated and the reaction quality is improved. By arranging the bottom scraping structure 27, the material located at the bottom of the reaction kettle 3 can be scraped off, so that the adhesion and residue of the material are avoided, and the utilization rate of the material is affected. By arranging the shearing structure 28, most of the large block of reactants in the reaction kettle 3 can be sheared, so that the quality of the intermediate product is improved. Preferably, the shearing structure 28 is in the shape of a disc, and a shearing knife extends outward from the outer periphery of the shearing structure 28. However, the shearing structure 28 can also be in other structures, and the specific structure can be determined according to the properties of the large block of reactants.

[0042] In the present application, the longitudinal stirring pipe 25 is in a tubular hollow structure, specifically in a longitudinally arranged serpentine pipe structure, which is in communication with the annular stirring pipe 26, and at the same time, a liquid cooling mechanism (not shown in the figure) and a rate control module 29 are arranged outside the reaction kettle 3, and the longitudinal stirring pipe 25 and the annular stirring pipe 26 are connected with the liquid cooling mechanism outside the reaction kettle 3. The longitudinal stirring pipe 25 in the longitudinally arranged serpentine pipe structure occupies a larger area size on the rotating surface, which can better realize the stirring function, and at the same time, the longitudinal stirring pipe 25 is provided with cooling liquid by the liquid cooling mechanism to realize the heat exchange between the longitudinal stirring pipe and the reaction cavity, so that the temperature in the reaction kettle 3 can be maintained at the required temperature for reaction, which is beneficial to promote the full reaction of the material and improve the reaction efficiency. The rate control module 29 is connected with the longitudinal stirring pipe 25, and the rate control module 29 is used for controlling the rotating speed of the longitudinal stirring pipe 25.
