[0031] Embodiment 1

[0032] With reference to Figures 1-2 The embodiment provides a high-temperature solid heat storage heat pile heat exchange strengthening structure, which comprises a heat storage heat pile 100 and a heat exchange assembly 200. The heat storage heat pile 100 is obtained by adding a heat storage function to an electric boiler, so that the electric heating is decoupled. The heat storage heat pile 100 can store heat in a valley electricity period and release heat in a peak electricity period. The heat storage heat pile 100 is internally provided with a ceramic heat pile for heat storage. The internal heat can be automatically adjusted through a control system, a water treatment system is started, soft water is generated, and a fan, a valve and the heat pile are controlled to work simultaneously, so that heat energy is delivered to the heat exchange system. The soft water continuously absorbs heat through the heat exchange system, is gradually heated, and finally forms overheat steam or saturated steam and other products required by users. The heat storage and heat exchange processes are prior art and will not be described in detail.

[0033] The heat storage heat pile 100 is provided with an output port 101. The overheat steam or the saturated steam can be delivered to the outside through the output port 101.

[0034] The heat exchange assembly 200 comprises a heat exchange pipe 201 connected with the output port 101. The heat exchange pipe 201 is provided with a safety assembly 300. When heat is required, the heat released directly from the heat storage heat pile 100 cannot be controlled, which may cause the overheat steam or the saturated steam to be overheated or the heat flow to be too large to meet the actual requirement. Therefore, the safety assembly 300 is arranged in the heat exchange pipe 201, so that the delivery of the overheat steam or the saturated steam is kept within a safe range.

[0035] The safety assembly 300 comprises a safety pipe 301 arranged in the heat exchange pipe 201. The safety pipe 301 is connected with the heat exchange pipe 201 at both ends.

[0036] The safety pipe 301 is provided with a first annular groove 301a, the inner diameter of the first annular groove 301a is greater than the inner diameter of the safety pipe 301, a rotating part 302 is arranged in the first annular groove 301a, the rotating part 302 is provided with a through channel, the rotating part 302 can rotate in the first annular groove 301a, a first opening 301b is arranged on the side of the first annular groove 301a and penetrates to the outside of the safety pipe 301, a second opening 302c is arranged on the side of the rotating part 302 and penetrates, it should be explained that the initial position of the rotating part 302 is set to 0°, at this time, the first opening 301b and the second opening 302c are completely staggered, when the rotating part 302 rotates 90°, the first opening 301b and the second opening 302c are coincided, so that the first opening 301b and the second opening 302c form an opening, the overheat steam or the saturated steam in the inside is discharged, and in the process that the position of the rotating part 302 is from 0° to 90°, the first opening 301b and the second opening 302c are from staggered to partially coincided, and then to completely coincided. When the first opening 301b and the second opening 302c are completely staggered, the safety pipe 301 is used as a pipeline to transmit the overheat steam or the saturated steam, when the first opening 301b and the second opening 302c have a coincided part, the overheat steam or the saturated steam is discharged from the coincided part of the first opening 301b and the second opening 302c.

[0037] In the embodiment, when the overheat steam or the saturated steam at the output end of the heat exchange pipe 201 is excessive, the first opening 301b and the second opening 302c can be operated to have a coincided part to discharge the excessive overheat steam or saturated steam.

[0038] Embodiment 2

[0039] Reference Figures 1-4 For the second embodiment of the application, the embodiment is based on the previous embodiment, and the difference between the embodiment and the previous embodiment is that:

[0040] The safety pipe 301 is further provided with a second annular groove 301e, the inner diameter of the second annular groove 301e is greater than the inner diameter of the safety pipe 301, a moving part 303 is arranged in the safety pipe 301, and a through hole is arranged in the moving part 303. The moving part 303 can move axially in the safety pipe 301.

[0041] The moving part 303 comprises a first section A inside the rotating part 302 and a second section B connected with the first section A. The outer diameter of the second section B is smaller than that of the first section A. The second section B is located in the second annular groove 301e and is provided with a limiting disc 303a. The third opening 303d is arranged on the side surface of the second section B, and the fourth opening 303e is arranged on the limiting disc 303a. The transmission path of the overheated steam or saturated steam in the safety pipe 301 is the rotating part 302, the first section A, the second section B, the third opening 303d and the fourth opening 303e, or the rotating part 302, the second opening 302c, the first opening 301b.

[0042] The inner side of the end of the rotating part 302 away from the second annular groove 301e is provided with an axial extending guide groove 302a, and the end of the guide groove 302a is connected with a spiral groove 302b. The outer side of the moving part 303 is provided with a first boss 303b, which is embedded in the guide groove 302a or the spiral groove 302b. When the first boss 303b moves in the guide groove 302a, the rotating part 302 and the moving part 303 do not rotate relatively. When the first boss 303b moves in the spiral groove 302b, the rotating part 302 and the moving part 303 will relatively spiral.

[0043] The side surface of the second annular groove 301e is provided with an axial extending limiting groove 301c, and the side surface of the limiting disc 303a is provided with a second boss 303c, which is embedded in the limiting groove 301c. Therefore, the moving part 303 cannot rotate, so when the first boss 303b moves in the spiral groove 302b, it will drive the rotating part 302 to deflect.

[0044] Further, the second annular groove 301e is provided with an adjusting ring 304, and the adjusting ring 304 and the limiting disc 303a are provided with an elastic member 305. The elastic member 305 is a spring, which pushes the first boss 303b of the moving part 303 to be in the guide groove 302a under the action of the spring.

[0045] In this embodiment, the maximum flow / pressure of the superheated steam or saturated steam that the device requiring heat can accept is set as a. When the flow / pressure of the superheated steam or saturated steam entering the safety pipe 301 is within a, the pressure of the superheated steam or saturated steam on the elastic member 305 is not large enough to make the length of the elastic member 305 shortened by a length that is not larger than the length of the guide groove 302a, and the pressure of the superheated steam or saturated steam on the limiting disc 303a is not large enough to push the first boss 303b to move in the guide groove 302a. At this time, the rotating member 302 is not deflected, and all the superheated steam or saturated steam can pass through the safety pipe 301. When the flow / pressure of the superheated steam or saturated steam entering the safety pipe 301 is greater than a, the pressure of the superheated steam or saturated steam is large enough to push the moving member 303 to make the first boss 303b move in the spiral groove 302b, and further drive the rotating member 302 to be deflected, so that the first opening 301b and the second opening 302c have a coinciding part to discharge the excess superheated steam or saturated steam. When the pressure inside the safety pipe 301 reaches a safety value, the rotating member 302 is automatically reset.

[0046] Preferably, the value of a is not fixed for different requirements, and thus the value of a needs to be adjusted. The specific method is as follows:

[0047] The third boss 304a is arranged on the outer periphery of the adjusting ring 304 and passes through the limiting groove 301c. The adjusting ring 304 can move along the limiting groove 301c. The third annular groove 301d is arranged on the outer periphery of the safety pipe 301. The rotating ring 306 is arranged in the third annular groove 301d. The internal thread 306a is arranged in the rotating ring 306. The third boss 304a is embedded in the groove formed by the internal thread 306a. The outer thread matched with the internal thread 306a is arranged on the outer periphery of the third annular groove 301d. Thus, the position of the adjusting ring 304 is changed by the rotating ring 306, and further the elastic force of the elastic member 305 is adjusted. When the value of a needs to be increased, the adjusting ring 304 is adjusted to be close to the rotating member 302 so that the compression amount of the elastic member 305 is increased. At this time, the elastic force and the elastic potential energy of the elastic member 305 are relatively large, and a relatively large value of a is needed to continue to compress the elastic member 305. Similarly, when the value of a needs to be decreased, the adjusting ring 304 is adjusted to be away from the rotating member 302 so that the compression amount of the elastic member 305 is decreased. At this time, the elastic force and the elastic potential energy of the elastic member 305 are relatively small, and a relatively small value of a can compress the elastic member 305.

[0048] In this embodiment, when the heat pile needs to exchange heat and provide heat to the device requiring heat, the heat is transported by the heat exchange assembly and the safety assembly. According to the actual requirement, the compression amount of the elastic member 305 is adjusted so that the heat supply is within a safe range.
