Description

Technical Field

[0001] The present invention relates to the field of energy-saving heat exchange devices, and in particular to a heat exchange condensing device and a silicon powder collecting device using the same. Background Art

[0002] Existing heat exchange devices all circulate the medium through annular pipes or wave pipes, and achieve the cooling effect through heat exchange of the medium. The present application is for preparing silicon powder by condensing the gasified silicon element. Ordinary heat exchange condensation devices will cause the silicon powder to adhere to the refrigeration pipeline, resulting in silicon powder loss. At the same time, a large amount of silicon powder adheres to the refrigeration pipeline, which will affect the cooling effect. Therefore, a new type of heat exchange condensation device is needed to solve the above problems. At the same time, the circulation path of the refrigerant medium will also affect the cooling effect and the amount of effective energy. Therefore, the overall structure needs to be designed considering the energy-saving effect. Summary of the Invention

[0009] Furthermore, the outer tube body includes an upper tube body and a lower tube body, the upper tube body is fixedly connected to the lower tube body, and the outer ring diameters of the upper tube body and the lower tube body are the same.

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0025] Example 1

[0026] See also Figure 1-3As shown, a heat exchange condensing device includes a condensing chamber 1, a lifting device 2, a scraper 3 and a heat exchange component 4, the lifting device 2 includes a lifting cylinder 10, a linear guide sleeve 11, a linear guide rod 12 and a guide fixing frame 13, the linear guide sleeve 11 passes through the medium dispersion chamber 7 and the medium recovery chamber 8 and is fixedly connected to the feed chamber and the medium recovery chamber 8, a linear guide rod 12 is slidably installed in the linear guide sleeve 11, one end of the linear guide rod 12 is fixedly connected to the scraper 3, and the other end of the linear guide rod 12 is slidably connected to the lifting cylinder 10 and the guide fixing frame 13 respectively, wherein the linear guide sleeve 11 is used for linear guidance of the linear guide rod 12 and is also used for sealing between the lifting device 2 and the condensing chamber 1;

[0027] An air inlet 5 and an exhaust port 6 are respectively provided on the side walls of the condensing chamber 1. An opening is also provided above the condensing chamber 1, at which a heat exchange component 4 is fixedly installed, and a lifting device 2 is fixedly installed on the heat exchange component 4. The output end of the lifting device 2 passes through the heat exchange component 4 and is fixedly connected to a scraper plate 3. The heat exchange component 4 includes a medium dispersion chamber 7, a medium recovery chamber 8 and a heat exchange pipeline 9. The lower end surface of the medium dispersion chamber 7 is connected to the condensing chamber 1, and a number of heat exchange pipelines 9 are fixedly installed on the lower end surface of the medium dispersion chamber 7. The scraper plate 3 is provided with scraping holes with the same number as the heat exchange pipelines 9. The heat exchange pipelines 9 are slidably inserted into the scraping holes and slidably connected to the scraper plate 3. A medium recovery chamber 8 is fixedly installed on the upper end surface of the medium dispersion chamber 7. The medium recovery chamber 8 and the medium dispersion chamber 7 are connected to the inner cavity of the heat exchange pipeline 9.

[0028] Both the medium dispersion cavity 7 and the medium recovery cavity 8 are provided with a medium cavity. The medium dispersion cavity 7 is used to evenly disperse the medium and output it into the heat exchange pipe. The medium recovery cavity 8 is used to recover the medium flowing back into the heat exchange pipe. The medium cavities are respectively connected to the inner cavity of the heat exchange pipe 9. A connecting port 14 is provided on the medium cavity of the medium dispersion cavity 7 and the medium recovery cavity 8. The connecting port 14 is used to connect to a refrigeration device to cool the medium through the refrigeration device, and the refrigeration medium is input and recovered respectively through the connecting port 14.

[0029] The heat exchange pipeline 9 includes an outer tube body 15 and an inner tube body 16. The inner tube body 16 is arranged in the cavity of the outer tube body 15. One end of the inner tube body 16 is fixedly connected to the medium recovery cavity 8. The tail end of the inner tube body 16 extends to the tail end inside the outer tube body 15, and a channel for medium circulation is provided between the tail end of the inner tube body 16 and the tail end of the outer tube body 15. The inner cavity of the outer tube body 15 is connected to the medium dispersion cavity 7.

[0030] The outer tube body 15 receives the refrigeration medium. After the refrigeration medium flows to the end of the outer tube body 15 , it flows back to the medium recovery cavity 8 through the end of the inner tube body 16 .

[0031] Example 2

[0032] The technical solution of this embodiment is substantially the same as that of embodiment 1, and the distinguishing feature is that the outer tube body 15 includes an upper tube body and a lower tube body, the upper tube body is fixedly connected to the lower tube body, and the outer ring diameters of the upper tube body and the lower tube body are the same.

[0033] A temperature insulating member is fixedly provided at the connection between the lower tube body and the upper tube body, and the temperature insulating member isolates the cavity between the upper tube body and the lower tube body.

[0034] After the cooling medium flows into the upper tube, it is isolated by the temperature insulation component and will not enter the lower tube, thus preventing the temperature from being transmitted to the lower tube. By setting this structure, the condensation of silicon powder at the bottom of the lower tube can be prevented as much as possible.

[0035] Example 3

[0036] The technical solutions of this embodiment are substantially the same as those of embodiment 2, with the difference being that the lower tube body is made of a thermal insulation material, is a solid tube, and has a length of no less than 5 cm.

[0037] This embodiment has the same technical effect as that of Embodiment 2 and is an alternative to Embodiment 2.

[0038] Example 4

[0039] The technical solution of this embodiment is roughly the same as that of one of embodiments 1-3, and the distinguishing feature is that a plurality of partition plates are provided in the medium cavity of the cut-off recovery cavity and the medium dispersion cavity 7, which divide the medium cavity into a plurality of independent cavities, and the plurality of independent cavities are connected by pipelines.

[0040] The partition plate is annular, and the independent cavities are connected in sequence from outside to inside. The connection port 14 for inputting the cooling medium is connected to the outermost independent cavity, while the connection port 14 for outflowing the cooling medium is connected to the innermost independent cavity.

[0041] An independent cavity is formed by the partition plate, and the outer heat exchange pipe 9 has the best cooling effect. This is because the outer side is the inflow layer of the refrigerant medium, and the cooling effect is the best. The energy of the refrigerant in the heat exchange pipe 9 will gradually be lost as it moves toward the center. However, the less silicon needs to be condensed as it moves toward the center. Moreover, the inner heat exchange pipe 9 is surrounded by the outer heat exchange pipe 9, and the condensation environment of the inner heat exchange pipe 9 is better than that of the outer heat exchange pipe 9, so that the inner heat exchange pipe 9 needs to consume less energy. Therefore, through the setting of this structure, a better condensation effect can be achieved, and energy consumption can be reduced at the same time.

The heat exchange condensation device 21 and the collection box 19 are connected to each other through the connection port 14. A condensation fixing frame 20 is set on the outside of the collection box 19, and the heat exchange condensation device 21 is fixedly installed on the condensation fixing frame 20.
