[0017] The present invention provides a single-system screw heat exchanger through improvement, which has the following improvements and advantages compared with the prior art:

[0018] First, in the present invention, the cold fluid is in the inner tube, and each inner tube has a heat source on the outer and inner peripheries, namely, hot fluid and hot gas, so that when the cold fluid flows through the inner tube, the cross-section of the cold fluid is annular, and the outer and inner peripheries of the annular shape can simultaneously perform heat exchange, thereby improving the heat exchange efficiency; and the cold fluid and the hot fluid flow in a straight line without the obstruction of the baffle, thereby increasing the flow rate while ensuring the heat exchange efficiency.

[0019] Second, the inner tube, the outer tube and the ventilation tube in the present invention are connected in a straight line without a thick outer wall of the tube shell, and the structure is simple, which is convenient for disassembly and assembly and maintenance.

[0020] Third: In the present invention, the first linear screw module drives the support plate to move to the left, so that multiple ventilation tubes are inserted into multiple air filling ports in the air pump, and then the air pump inputs gas into the ventilation tube. Then the second linear screw module drives the mounting plate and the air pump to move to the right, and the first linear screw module drives the ventilation tube to move right synchronously. The ventilation tube and the air pump are relatively still, thereby ensuring that the gas can be stably in the ventilation tube, thereby exchanging heat with the cold fluid. After the ventilation is completed, the second linear screw module first drives the mounting plate and the air pump to move to the right, so that the air pump is separated from the ventilation tube, thereby releasing the gas, and repeating the above actions to achieve gas replacement, thereby ensuring the gas-liquid heat exchange efficiency.

[0021] Fourthly, in the present invention, when air is inflated, multiple airbags will expand, so that the airbags will squeeze the cold liquid inside the inner tube, so that the outer periphery of the cold liquid cross section is in close contact with the inner wall of the inner tube and has pressure, and the inner periphery of the cold liquid cross section is in close contact with the outer periphery of the airbag and has pressure. Under the action of pressure, the heat exchange efficiency is improved. Although the expansion of the airbag will reduce the space for liquid flow, the flow rate of the liquid will increase, so it will not affect the flow rate of the liquid per unit time.

[0022] Fifth: In the present invention, the airbag will move to the right along with the ventilation tube after expansion, and the rightward movement can cooperate with the rightward movement of the fluid, timely providing space for the liquid to move to the right, reducing the pressure of the pump body, and avoiding the imbalance of the internal pressure of the inner tube after the airbag expands. When the air pump moves to the left, the airbag shrinks, thereby facilitating the airbag to reset to the left along with the ventilation tube, and multiple airbags can squeeze the fluid in the same interval multiple times, further improving the heat exchange efficiency.

[0023] Sixth: In the present invention, the rotating motor drives the transmission gear plate to rotate, and the transmission gear plate drives multiple ventilation tubes to rotate through multiple second gears. When the ventilation tubes rotate, they can drive multiple air bags and brushes to rotate. With the expansion effect of the air bags, the brushes can scrape the inner circumferential wall of the inner tube, thereby cleaning the inner circumferential wall of the inner tube in real time, reducing the residual impurities, and thus improving the cleaning and maintenance cycle of the inner tube.

[0039] like Figure 1-Figure 8 As shown, an embodiment of the present invention provides a single-system screw heat exchanger, including a bottom plate 1, a water inlet jacket 2, a water outlet jacket 3, and a gas component. A plurality of outer tubes 201 are fixedly connected in the water inlet jacket 2, and a plurality of inner tubes 301 are fixedly connected in the water outlet jacket 3. The diameter of the inner tube 301 is smaller than that of the outer tube 201. The inner tube 301 penetrates the outer tube 201 at a corresponding position. One end of the inner tube 301 away from the water inlet jacket 2 is fixedly connected to the liquid inlet jacket 4. A slide rail 101 is fixedly connected to the bottom of the bottom plate 1. A support seat 102 is fixedly connected to the outer peripheral wall of the water inlet jacket 2 and the water outlet jacket 3. The support seat 102 at the bottom of the water inlet jacket 2 is slidably connected to the slide rail 101. The support seat 102 at the bottom of the water outlet jacket 3 is fixedly connected to the bottom plate 1. One end of the inner tube 301 away from the water inlet jacket 2 is sealedly connected to the water outlet jacket 3, and one end of the inner tube 301 is inserted into the inner cavity of the liquid inlet jacket 4, and the other end of the inner tube 301 penetrates the water inlet jacket 2.

[0040] The gas component includes a plurality of ventilation tubes 5 and a gas filling component. The ventilation tubes 5 penetrate the corresponding inner tubes 301 and the liquid inlet sleeves 4 .

[0041] Specifically: the hot fluid flows into the multiple outer tubes 201 through the water inlet jacket 2, and then flows out from the water outlet jacket 3; the cold fluid enters the multiple inner tubes 301 through the liquid inlet jacket 4, and then flows out from the right end of the inner tube 301; the gas filling component introduces hot gas into the ventilation pipe 5;

[0042] It can be understood that the cold fluid is in the inner tube 301, and each inner tube 301 has a heat source on its outer periphery and inner periphery, i.e., hot fluid and hot gas, so that when the cold fluid flows through the inner tube 301, the cross section of the cold fluid is annular, and the outer periphery and inner periphery of the annular shape can simultaneously perform heat exchange, thereby improving the heat exchange efficiency;

[0043] Moreover, compared with the existing shell and tube heat exchanger, the cold fluid and the hot fluid flow in a straight line without the obstruction of the baffle, so that the present invention can ensure the heat exchange efficiency while increasing the flow rate;

[0044] The inner tube 301, the outer tube 201 and the ventilation tube 5 are connected in a straight line without a thick outer wall of the tube shell, and the structure is simple, which is convenient for disassembly and assembly and maintenance.

[0045] Both the water inlet jacket 2 and the water outlet jacket 3 have cavities inside. The cavity inside the water inlet jacket 2 is connected to one end of the multiple outer tubes 201, and the cavity inside the water outlet jacket 3 is connected to the other end of the outer tube 201. A water inlet pipe 202 is fixedly connected to the top of the water inlet jacket 2, and a water outlet 302 is provided at the bottom of the water outlet jacket 3. The inner cavity of the liquid inlet jacket 4 is connected to the multiple inner tubes 301, and a liquid inlet 401 is provided at the top of the liquid inlet jacket 4. The water inlet pipe 202 and the liquid inlet 401 are connected to the external pump body structure to realize the pumping of liquid medium, and finally flow into the outer tube 201 or the inner tube 301 through the cavity.

[0046] A plurality of sealing openings are provided on the water inlet jacket 2 and the water outlet jacket 3 , and the inner tube 301 passes through the sealing openings at corresponding positions.

[0047] The air filling assembly includes an air pump 501 and a support plate 502. One side of the support plate 502 is rotatably connected to one end of a plurality of ventilation tubes 5. One end of the ventilation tube 5 is in a sealed state, and the other end of the ventilation tube 5 has an opening.

[0048] The inflation assembly also includes a mounting plate 503, which is fixedly connected to the air pump 501. The air pump 501 is fixedly connected with a plurality of inflation ports, which penetrate the mounting plate 503. The air pump 501 inflates the ventilation tube 5 through the inflation ports.

[0049] A first linear screw module 504 and a second linear screw module 505 are fixedly connected to the base plate 1. The top of the first linear screw module 504 is connected to the support plate 502, and the first linear screw module 504 is used to control the support plate 502 to move back and forth in a straight line. The top of the second linear screw module 505 is connected to the mounting plate 503, and the second linear screw module 505 is used to control the mounting plate 503 to move back and forth in a straight line.

[0050] A plurality of air bags 506 are sealed and connected to the ventilation pipe 5 .

[0051] Specifically: the first linear screw module 504 drives the support plate 502 to move to the left, so that the multiple ventilation tubes 5 are inserted into the multiple air filling ports in the air pump 501, and then the air pump 501 inputs the gas into the ventilation tube 5, and then the second linear screw module 505 drives the mounting plate 503 and the air pump 501 to move to the right, and the first linear screw module 504 drives the ventilation tube 5 to move right synchronously, and the ventilation tube 5 and the air pump 501 are relatively still, so as to ensure that the gas can be stably in the ventilation tube 5, so as to exchange heat with the cold fluid. After the ventilation is completed, the second linear screw module 505 first drives the mounting plate 503 and the air pump 501 to move to the right, so that the air pump 501 is separated from the ventilation tube 5, so as to release the gas, and repeat the above actions to realize the replacement of the gas, thereby ensuring the gas-liquid heat exchange efficiency;

[0052] It is worth noting that: when the air is inflated, the multiple airbags 506 will expand, so that the airbags 506 will squeeze the cold liquid inside the inner tube 301, so that the outer periphery of the cross section of the cold liquid is in close contact with the inner wall of the inner tube 301 and has pressure, and the inner periphery of the cross section of the cold liquid is in close contact with the outer periphery of the airbags 506 and has pressure. Under the action of pressure, the heat exchange efficiency is improved. Although the expansion of the airbags 506 will reduce the space for the liquid to flow, the flow rate of the liquid will increase, so it will not affect the flow rate of the liquid per unit time.

[0053] Moreover, after being inflated, the airbag 506 will move to the right along with the ventilation tube 5. The rightward movement can cooperate with the rightward movement of the fluid, timely providing space for the liquid to move to the right, reducing the pressure of the pump body, and avoiding the imbalance of the internal pressure of the inner tube 301 caused by the airbag 506 after expansion. When the air pump 501 moves to the left, the airbag 506 shrinks, thereby facilitating the airbag 506 to reset to the left along with the ventilation tube 5, and multiple airbags 506 can squeeze the fluid in the same interval multiple times, further improving the heat exchange efficiency.

[0054] A rotating motor 507 is also fixedly connected to the support plate 502, and a transmission gear plate 508 is rotatably connected to the support plate 502. A first gear 509 is fixedly connected to the outer peripheral wall of the output shaft of the rotating motor 507, and the outer peripheral wall of the transmission gear plate 508 is meshingly connected to the first gear 509. A second gear 510 is fixedly connected to the outer peripheral wall of each ventilation pipe 5, and the second gear 510 is meshingly connected to the inner peripheral wall of the transmission gear plate 508. The outer peripheral wall of the airbag 506 has a brush.

[0055] Specifically: the rotating motor 507 drives the transmission gear plate 508 to rotate, and the transmission gear plate 508 drives the multiple ventilation tubes 5 to rotate through the multiple second gears 510. When the ventilation tubes 5 rotate, they can drive the multiple air bags 506 and the brushes to rotate. With the expansion effect of the air bags 506, the brushes can scrape the inner wall of the inner tube 301, thereby cleaning the inner wall of the inner tube 301 in real time, reducing the residual impurities, and thus improving the cleaning and maintenance cycle of the inner tube 301.

[0056] A mounting frame 511 is fixedly connected to the bottom of the support plate 502, and the mounting frame 511 is connected to the slider on the first linear screw module 504. The mounting frame 511 is fixed to the slider by bolts, which is convenient for disassembly and assembly, so that the support plate 502 and multiple ventilation tubes 5 can be pulled out from the inner tube 301, and then the inner tube 301 and the outer tube 201 can be disassembled and assembled. The structure is simple and the operation is convenient.

[0057] A filter box 6 is also provided on the base plate 1, and a connecting pipe 601 is fixedly connected to the top of the filter box 6, and the connecting pipe 601 is connected to the water outlet 302 through a pipeline. A discharge pipe 602 is provided at the bottom of the filter box 6, and a filter cavity 603 is provided inside the filter box 6, and a filter net 604 is fixedly connected to the filter cavity 603. A through groove 605 is provided on one side of the filter cavity 603, and a linkage rod 606 is connected through the through groove 605. A cleaning block 607 is fixedly connected to one end of the linkage rod 606, and a brush is provided on the lower end surface of the cleaning block 607. The other end of the linkage rod 606 is fixedly connected to a slider in the first linear screw module 504.

[0058] Specifically: the liquid discharged from the water outlet 302 contains impurities, which are filtered through the filter box 6 and then discharged from the discharge pipe 602. It can be understood that the hot fluid directly contacts the inner peripheral wall of the outer tube 201, and the hot fluid also directly contacts the outer peripheral wall of the inner tube 301. Under the action of high temperature, the inner peripheral wall of the outer tube 201 and the outer peripheral wall of the inner tube 301 are prone to produce oxidized impurities. Through the filtering treatment of the filter box 6, the liquid flowing out of the water outlet 302 can be reused, effectively saving water resources;

[0059] During the gas replacement, the slider on the first linear screw module 504 will simultaneously drive the linkage rod 606 to synchronously move back and forth in a straight line, so that the brush under the cleaning block 607 can clean the filter 604, effectively ensuring the filtering effect of the filter 604 and improving the filtering speed.

[0060] Working principle: hot fluid flows into multiple outer tubes 201 through the water inlet jacket 2, and then flows out from the water outlet jacket 3, cold fluid enters multiple inner tubes 301 through the liquid inlet jacket 4, and then flows out from the right end of the inner tube 301, and at the same time, the first linear screw module 504 drives the support plate 502 to move to the left, so that multiple ventilation pipes 5 are inserted into multiple air filling ports in the air pump 501, and then the air pump 501 inputs gas into the ventilation pipe 5, and then the second linear screw module 505 drives the mounting plate 503 and the air pump 501 to move to the left side. The pump 501 moves to the right, and the first linear screw module 504 drives the ventilation pipe 5 to move right synchronously. The ventilation pipe 5 and the air pump 501 are relatively still, thereby ensuring that the gas can be stably in the ventilation pipe 5, thereby exchanging heat with the cold fluid. After the ventilation is completed, the second linear screw module 505 first drives the mounting plate 503 and the air pump 501 to move to the right, so that the air pump 501 is separated from the ventilation pipe 5, thereby releasing the gas, and repeating the above actions to realize the replacement of gas and fluid, thereby ensuring the gas-liquid and liquid-liquid heat exchange efficiency.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
