[0021] Embodiment 1 As Figure 1The embodiment provides a self-adaptive temperature mixing molten salt storage tank, which comprises a tank body 1, an electric heat tracing assembly connected to the tank body 1, a bearing body 2, a bottom of the tank body 1 and the bearing body 2 being rotationally connected, a first container and a second container connected to two sides of the tank body 1 respectively and having equal weight, a first thermal chemical material 31 contained in the first container, a second thermal chemical material 32 contained in the second container, the initial weight of the first thermal chemical material 31 being equal to the initial weight of the second thermal chemical material 32, a first heat conducting sheet 41, one end of the first heat conducting sheet 41 being connected to the first thermal chemical material 31, the other end of the first heat conducting sheet 41 extending to molten salt in the middle of the tank body 1, a second heat conducting sheet 42, one end of the second heat conducting sheet 42 being connected to the second thermal chemical material 32, the other end of the second heat conducting sheet 42 extending to molten salt on the side wall of the tank body 1, a transmission body 5 connected to the tank body 1, a stirring assembly 7 at least partially located in the molten salt in the tank body 1, the stirring assembly 7 and the transmission body 5 being connected through a transmission assembly 6, and wherein the first thermal chemical material 31 and the second thermal chemical material 32 are used for oxidation and reduction reactions, so that the two have weight difference, the tank body 1 rotates around the bearing body 2, and then drives the transmission body 5, the transmission assembly 6 and the stirring assembly 7 to move in turn.

[0022] Specifically, the tank body 1 is used for storing molten salt; the electric heat tracing assembly is used for assisting in controlling the temperature of the molten salt in the tank body 1, and the electric heat tracing assembly can specifically include an electric heat tracing pipe, a temperature sensor, a controller and the like; the carrier 2 is used for carrying the tank body 1, and a rotating pair is formed between the carrier 2 and the bottom of the tank body 1, so as to facilitate the left and right tilting of the tank body 1, wherein the carrier 2 can specifically include an axle body 21 and a base 22 connected with each other, and the bottom of the tank body 1 is rotationally connected with the axle body 21; the first and second thermal chemical materials 31 and 32 increase and decrease in weight by means of oxidation and reduction reactions, and realize heat release and heat absorption; since the first and second thermal chemical materials 31 and 32 are equal in weight, the tank body 1 can be kept in a balanced state when no oxidation and reduction reactions occur; the first heat-conducting sheet 41 is used for realizing heat transfer between the first thermal chemical material 31 and the molten salt in the middle part of the tank body 1, and the second heat-conducting sheet 42 is used for realizing heat transfer between the second thermal chemical material 32 and the molten salt on the side wall of the tank body 1; the materials of the first and second heat-conducting sheets 41 and 42 can be nickel-based alloy, stainless steel or the like; although the positions of the first and second heat-conducting sheets 41 and 42 are asymmetric about the tank body 1, since the first and second heat-conducting sheets 41 and 42 are in the form of sheets and have small weight, the tank body 1 can be kept in a balanced state when no oxidation and reduction reactions occur; of course, the weight ratio of the first and second heat-conducting sheets 41 and 42 can be adjusted to further keep the tank body 1 in a balanced state when no oxidation and reduction reactions occur; the transmission body 5 is carried by the tank body 1 and tilts left and right along with the tank body 1, so as to drive the stirring assembly 7 to stir the molten salt through the transmission assembly 6; the stirring assembly 7 and the transmission assembly 6 can be supported by relevant supports; preferably, the first and second containers are symmetrically arranged about the central longitudinal section of the tank body 1; since the first container contains the first thermal chemical material 31 and the second container contains the second thermal chemical material 32, the first and second thermal chemical materials 31 and 32 are also symmetrically arranged about the central longitudinal section of the tank body 1, so as to ensure that the tank body 1 is in a balanced state.

[0023] The working principle of the self-adaptive mixed-temperature molten salt storage tank according to the present application is described below with reference to a specific embodiment, and the embodiment is applicable to a cold salt tank, the designed operating temperature of the stored molten salt is 290℃, and the first and second thermal chemical materials 31 and 32 are both mixed materials mainly containing MnO2 and additionally containing other metal oxides such as Fe2O3, ZrO2 and CuO (the mixed materials can increase the performance of the thermal chemical cycle reaction); when the mixed materials exceed 350℃, the reduction reaction starts to occur, and when the mixed materials are lower than 270℃, the oxidation reaction starts to occur. (1) Working condition one: molten salt storage and heat exchange system shutdown working condition When the molten salt storage and heat exchange system is not running, the tank 1 stores 300℃ molten salt and naturally dissipates heat; the on-off trigger temperature of the electric heat tracing assembly of the tank 1 is set to 290℃, when the molten salt temperature naturally dissipates to below 290℃, the electric heat tracing assembly is triggered to start, at this time, the molten salt near the inner edge wall of the tank 1 is heated first, and then gradually transmitted to the molten salt in the middle through heat conduction, therefore, there is a heat conduction temperature difference between the molten salt of the edge wall and the molten salt in the middle; the molten salt temperature in the middle can be transmitted to the first thermochemical material 31 through the first heat conduction sheet 41, and the molten salt temperature of the edge wall can be transmitted to the second thermochemical material 32 through the second heat conduction sheet 42, and the temperature difference between the molten salt and the first thermochemical material 31 or the second thermochemical material 32 is about 20℃.

[0024] When the molten salt in the middle falls to 290℃ and is not heated in time, the temperature of the first thermochemical material 31 is about 270℃, triggering its oxidation reaction, absorbing O element in the air, increasing weight, and further causing the weight of the left side of the tank 1 to be higher than that of the right side, the tank 1 starts to drive the transmission body 5 to tilt to the left, the transmission body 5 drives the stirring assembly 7 to rotate through the transmission assembly 6, the stirring assembly 7 stirs the molten salt, so that the molten salt in the middle rises to 290℃ in advance, reducing the heating time of the electric heat tracing assembly; at the same time, the oxidation reaction is an exothermic reaction, which can transmit heat back to the molten salt through the first heat conduction sheet 41, and can avoid further temperature drop of the molten salt and the risk of freezing.

[0025] (2) Working condition two: molten salt storage and heat exchange system running working condition When the molten salt storage and heat exchange system is running, the tank 1 will receive 300-400℃ molten salt in the molten salt storage and heat exchange system, causing local high temperature in the tank 1, which will make the molten salt temperature output by the tank 1 uneven, which is not conducive to the stable operation of the molten salt storage and heat exchange system.

[0026] But when the molten salt storage heat exchange system is in the working condition of the molten salt being transported at 300-400 ℃, the temperature of the local area of the tank body 1 is high, and when the molten salt is transported at the edge wall of the tank body 1, the temperature of the edge wall is too high, and when the molten salt is transported near the middle part, the temperature of the middle part is too high; if the temperature of the middle part exceeds 370 ℃ and the temperature of the edge wall is lower than 370 ℃ (the case that the temperature of the middle part is lower than 370 ℃ and the temperature of the edge wall exceeds 370 ℃ is similar, and is not described here), the reduction reaction of the first thermochemical material 31 on the left will be triggered, and the O element will be released to reduce the weight, and then the balance state of the tank body 1 will be broken to tilt to the right, the transmission body 5 drives the stirring assembly 7 to rotate through the transmission assembly 6, the stirring assembly 7 stirs the molten salt, the temperature of the middle part is reduced, and the temperature of the edge wall is increased, until the temperature of the middle part and the temperature of the edge wall are equal, the temperature consistency of the molten salt in the tank body 1 and the output temperature consistency of the tank body 1 are ensured, and the operation and regulation of the molten salt storage heat exchange system are beneficial; if both the temperature of the edge wall and the temperature of the middle part exceed 370 ℃, and the temperature of the middle part is higher than the temperature of the edge wall (the case that the temperature of the middle part is lower than the temperature of the edge wall is similar, and is not described here), the reduction reaction of both the first thermochemical material 31 on the left and the second thermochemical material 32 on the right will be triggered, and the degree of the reduction reaction of the first thermochemical material 31 on the left with higher temperature is large, and the weight reduction amount is large, which will still cause the balance state of the tank body 1 to be broken to tilt to the right, the transmission body 5 drives the stirring assembly 7 to rotate through the transmission assembly 6, the stirring assembly 7 stirs the molten salt, the temperature of the middle part with higher temperature is reduced, and the temperature of the edge wall with lower temperature is increased, until the temperature of the middle part and the temperature of the edge wall are equal, in the process, the temperature of the middle part is always greater than or equal to the temperature of the edge wall, so that the temperature of the first thermochemical material 31 on the left is always greater than or equal to the temperature of the second thermochemical material 32 on the right, and then the degree of the reduction reaction and the weight reduction amount of the first thermochemical material 31 on the left are always greater than or equal to the degree of the reduction reaction and the weight reduction amount of the second thermochemical material 32 on the right, finally the tank body 1 is in a state of tilting to the right, the temperature consistency of the molten salt in the tank body 1 and the output temperature consistency of the tank body 1 are ensured, and the operation and regulation of the molten salt storage heat exchange system are beneficial; at the same time, the reduction reaction absorbs heat, and the energy of the local overheated molten salt is stored in the first thermochemical material 31 and the second thermochemical material 32, which can release heat when the molten salt storage heat exchange system is in the shutdown working condition, and the power consumption of the electric heat tracing assembly is reduced.

[0027] In summary, the self-adaptive temperature mixing molten salt storage tank of the embodiment not only realizes weight increase and reduction through the oxidation and reduction reactions of the first and second thermal chemical materials 31 and 32, facilitates self-adaptive temperature mixing of the molten salt, ensures heating uniformity, does not need an electric stirring assembly, and facilitates energy consumption reduction. In addition, the self-adaptive temperature mixing molten salt storage tank of the embodiment realizes heat release and absorption through the oxidation and reduction reactions of the first and second thermal chemical materials 31 and 32, facilitates use time reduction of the electric heat tracing assembly, and further facilitates energy consumption reduction.

[0028] Further, as Figure 1 , the first and second thermal chemical materials 31 and 32 are each provided with a plurality of through holes.

[0029] Specifically, the plurality of through holes facilitate the first and second thermal chemical materials 31 and 32 to present a porous shape, thereby facilitating sufficient contact of air with the first and second thermal chemical materials 31 and 32 and ensuring good oxidation and reduction performance.

[0030] Further, as Figure 1 , the first container is replaceably filled with the first thermal chemical material 31, and the second container is replaceably filled with the second thermal chemical material 32; and / or, further comprising: a first temperature control assembly connected with the first thermal chemical material 31; and a second temperature control assembly connected with the second thermal chemical material 32.

[0031] Specifically, the first thermo-chemical material 31 is replaceably arranged in the first container, and the second thermo-chemical material 32 is replaceably arranged in the second container, so as to realize replacement of the first thermo-chemical material 31 and the second thermo-chemical material 32, and replace new first thermo-chemical material 31 and second thermo-chemical material 32 with equal weight after each working condition one and working condition two. Since the first thermo-chemical material 31 is oxidized in working condition one, or the first thermo-chemical material 31 and / or the second thermo-chemical material 32 is reduced in working condition two, the tank body 1 is in an inclined state after the molten salt is stirred uniformly, so that the replaceable thermo-chemical material can ensure the balance state of the two sides of the tank body 1. Since the first thermo-chemical material 31 in working condition one can reach a stable state that cannot be further oxidized, and the first thermo-chemical material 31 and / or the second thermo-chemical material 32 in working condition two can reach a stable state that cannot be further reduced, the replaceable thermo-chemical material can ensure continuous oxidation and reduction, thereby not affecting the subsequent use of the self-adaptive mixed-temperature molten salt storage tank of the present scheme. The specific replacement mode of the thermo-chemical material has multiple modes, such as mode one, the first container and the second container are fixedly connected with the tank body 1, and only the first thermo-chemical material 31 and the second thermo-chemical material 32 are replaced, mode two, the first container and the second container are detachably connected with the tank body 1, and the first container and the first thermo-chemical material 31, and the second container and the second thermo-chemical material 32 can be replaced synchronously, or the first container containing the first thermo-chemical material 31 and the second container containing the second thermo-chemical material 32 are taken out, and only the first thermo-chemical material 31 and the second thermo-chemical material 32 are replaced, mode three, the first container is detachably connected with a first box, the first box is replaceably arranged with the first thermo-chemical material 31, the second container is detachably connected with a second box, and the second box is replaceably arranged with the second thermo-chemical material 32. The first box and the first thermo-chemical material 31, and the second box and the second thermo-chemical material 32 can be replaced synchronously, or the first box containing the first thermo-chemical material 31 and the second box containing the second thermo-chemical material 32 are taken out, and only the first thermo-chemical material 31 and the second thermo-chemical material 32 are replaced.

[0032] The first temperature control assembly and the second temperature control assembly are correspondingly arranged. For the first thermochemical material 31 in the oxidation reaction in the working condition one, the first temperature control assembly can heat the temperature of the first thermochemical material 31 to above 350 DEG C, so that the first thermochemical material 31 has a reduction reaction for a preset time, thereby making the weight of the first thermochemical material 31 and the weight of the second thermochemical material 32 equal again. Since the first thermochemical material 31 in the working condition one has the oxidation reaction, after the molten salt is stirred uniformly, the tank body 1 presents an inclined state, so that the first temperature control assembly can ensure the balance state of the two sides of the tank body 1. Since the first thermochemical material 31 in the working condition one can reach a stable state that cannot be further oxidized, the first temperature control assembly can ensure that the thermochemical material continues to oxidize, thereby not affecting the subsequent use of the self-adaptive mixed temperature molten salt storage tank of the scheme. Meanwhile, the reduction reaction for the preset time is endothermic, which facilitates the release of the heat stored in the first thermochemical material 31 and the second thermochemical material 32 when the molten salt storage and heat exchange system is in the shutdown working condition, thereby reducing the power consumption of the electric heat tracing assembly. For the first thermochemical material 31 and / or the second thermochemical material 32 in the reduction reaction in the working condition two, the first temperature control assembly and / or the second temperature control assembly can cool the temperature of the first thermochemical material 31 and / or the second thermochemical material 32 to below 270 DEG C (which can also be naturally cooled), so that the first thermochemical material 31 and / or the second thermochemical material 32 has an oxidation reaction for a preset time, thereby making the weight of the first thermochemical material 31 and the weight of the second thermochemical material 32 equal again. Since the first thermochemical material 31 and / or the second thermochemical material 32 in the working condition two has the reduction reaction, after the molten salt is stirred uniformly, the tank body 1 presents an inclined state, so that the first temperature control assembly and / or the second temperature control assembly can ensure the balance state of the two sides of the tank body 1. Since the first thermochemical material 31 and / or the second thermochemical material 32 in the working condition two can reach a stable state that cannot be further reduced, the first temperature control assembly and / or the second temperature control assembly can ensure that the thermochemical material continues to reduce, thereby not affecting the subsequent use of the self-adaptive mixed temperature molten salt storage tank of the scheme. Meanwhile, the oxidation reaction for the preset time is an exothermic reaction, which can return the heat to the molten salt through the first heat conduction sheet 41 and the second heat conduction sheet 42, thereby avoiding the further cooling of the molten salt and the risk of freezing. The first temperature control assembly and the second temperature control assembly have the same structure, and both include an electric heating pipe for heating, a temperature sensor and the like. In order to increase the cooling efficiency, the first temperature control assembly and the second temperature control assembly can further include a cooling unit, and the electric heating pipe and the cooling unit are inserted into the thermochemical material.

[0033] Further, as shown in FIG. 1, the first heat conduction sheet 41 and the second heat conduction sheet 42 are arranged on the inner wall of the tank body 1, and the first heat conduction sheet 41 and the second heat conduction sheet 42 are arranged in the same direction, and the first heat conduction sheet 41 and the second heat conduction sheet 42 are arranged in the same direction. Figures 4-5The first heat-conducting sheet 41 and the second heat-conducting sheet 42 are identical in structure and each include a plurality of branch strips 401, the plurality of branch strips 401 of the first heat-conducting sheet 41 are connected to the first thermal chemical material 31, and the plurality of branch strips 401 of the second heat-conducting sheet 42 are connected to the second thermal chemical material 32.

[0034] Specifically, the plurality of branch strips 401 are used to increase the contact area with the first thermal chemical material 31 or the second thermal chemical material 32, thereby improving the heat transfer efficiency, and the specific number of the plurality of branch strips 401 is not limited and can be four, five, etc., and the plurality of branch strips 401 preferably present a radial shape.

[0035] Further, as shown in Figures 4-5 The first heat-conducting sheet 41 and the second heat-conducting sheet 42 are identical in structure and each include a plurality of branch strips 401, the plurality of branch strips 401 of the first heat-conducting sheet 41 are connected to the first thermal chemical material 31, and the plurality of branch strips 401 of the second heat-conducting sheet 42 are connected to the second thermal chemical material 32.

[0036] Specifically, the plurality of branch strips 401 are used to increase the contact area with the first thermal chemical material 31 or the second thermal chemical material 32, thereby improving the heat transfer efficiency, and the specific number of the plurality of branch strips 401 is not limited and can be four, five, etc., and the plurality of branch strips 401 preferably present a radial shape.

[0037] Further, as shown in Figure 1 Further, the first elastic member 81 and the second elastic member 82 are further included and are respectively connected to two sides of the bottom of the tank body 1, the first elastic member 81 and the first thermal chemical material 31 are arranged in correspondence in the vertical direction, and the second elastic member 82 and the second thermal chemical material 32 are arranged in correspondence in the vertical direction.

[0038] Specifically, the first elastic member 81 and the second elastic member 82 can play a buffering role on the one hand to avoid the tank body 1 from instantaneously falling down, and can absorb and re-release the gravitational potential energy on the other hand, so that the tank body 1 can be reset to a certain extent. It needs to be noted that, due to the weight change caused by the oxidation and reduction reaction of the first thermal chemical material 31 and the second thermal chemical material 32 during work, it is difficult to ensure that the weights of the two are equal again, so the first elastic member 81 and the second elastic member 82 can only assist the tank body 1 to reset to a certain extent, but not in a balanced state. The first elastic member 81 and the first thermal chemical material 31 do not need to be located on the same vertical line, but only need to be in correspondence, and a certain positional difference in the vertical direction is allowed. The second elastic member 82 and the second thermal chemical material 32 are the same. The material of the first elastic member 81 and the second elastic member 82 can be carbon spring steel, rubber, etc.

[0039] Further, as shown in Figure 1The first elastic member 81 comprises a spring, an elastic pad or an elastic rope.

[0040] Specifically, the specific form of the first elastic member 81 and the second elastic member 82 is not limited, which can be a spring, an elastic pad or an elastic rope, etc. The elastic rope is used in cooperation with the support rod, the first end of the elastic rope is connected with the support rod, the second end of the elastic rope is connected with the bottom of the tank body 1, and the height of the first end is higher than that of the second end.
