Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology for refrigeration systems, and specifically to a direct-cooling cryogenic condenser. Background Technology

[0002] Direct-cooling cryogenic condensers are core heat exchange equipment in industrial refrigeration systems. Their basic structure consists of a condenser shell, end cylinders, end covers, support plates, heat exchange tubes, and partition plates. They are key components in the refrigeration system for refrigerant condensation and heat exchange. During operation, the cooling medium flows within the heat exchange tubes. The high-temperature gaseous refrigerant, blocked and guided by the partition plates, prolongs its contact time with the heat exchange tubes. Heat is transferred to the cooling medium through the highly conductive copper heat exchange tubes, causing the gaseous refrigerant to condense into a liquid state and be discharged, thus achieving cyclic refrigeration in the refrigeration system.

[0003] However, during long-term operation, the inner walls of the heat exchange tubes are easily clogged by scale and deposits due to factors such as the quality of the cooling medium and refrigerant impurities. This leads to a significant decrease in heat exchange efficiency, increased energy consumption and reduced refrigeration performance, and in severe cases, system shutdown, affecting production operations. When only some heat exchange tubes are blocked, the existing condenser structure cannot selectively and precisely clear specific blocked pipes, requiring complete disassembly and maintenance of all end caps. This not only increases maintenance costs but also damages the equipment's sealing structure, leading to condensate leakage and affecting the refrigeration system's sealing and operational stability. Furthermore, the complete shutdown required during disassembly and maintenance further reduces the refrigeration system's operating efficiency. Therefore, existing direct-cooling cryogenic condensers have significant shortcomings in terms of maintenance convenience, operational stability, and adaptability to the long-term operational needs of refrigeration systems, and urgently require improvement. Summary of the Invention

[0004] This invention provides a direct-cooling cryogenic condenser to solve the problems of blockage or fouling of heat exchange tubes, which require extensive disassembly for cleaning, have high maintenance costs, and are prone to damaging the equipment's sealing structure, affecting the stability of equipment operation, and making it impossible to clean blockages and fouling without shutting down the machine.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] In a first aspect, a direct-cooling cryogenic condenser includes a condenser shell and end cylinders fixed to both ends of the condenser shell. The ends of the end cylinders are connected to end caps via fixing components. Support plates are symmetrically arranged on the inner side of the condenser shell. Multiple heat exchange tubes are uniformly arranged through the interior of the support plates. Multiple partition plates are spaced apart on the outer side of the heat exchange tubes to block and guide high-temperature gaseous refrigerant, thereby prolonging its contact time with the heat exchange tubes. The condenser also includes:

[0007] The unblocking section, which is sealed through the end cap and corresponds one-to-one with the position of each heat exchange tube, is used to selectively insert and unblock specific heat exchange tubes when blockage occurs, ensuring the heat exchange stability of the refrigeration system. The unblocking section includes an adjusting support and a sealing insert. The adjusting support is rotatably inserted through the end cap and is used to provide rotational support for the sealing insert and adjust the axial extension state of the sealing insert to meet the unblocking requirements under refrigeration conditions. The sealing insert is threaded through the adjusting support and is used to axially push and insert into the corresponding heat exchange tube when the adjusting support rotates, thereby disturbing and unblocking the blockage and preventing the refrigeration efficiency from decreasing due to blockage. In the working state, it cooperates with the sealing structure on the end cap to prevent the condensate in the end cylinder from leaking outward and to ensure the airtightness of the refrigeration system.

[0008] An adjustment drive unit is disposed on the outside of the end cylinder and extends to one side of the end cover, for selectively driving the adjustment support member at the target position to rotate; the adjustment drive unit includes a drive connector and an adjustment drive member, the drive connector being fixed on the end cylinder; the adjustment drive member is disposed on one side of the drive connector.

[0009] Furthermore, the adjusting support includes:

[0010] The bearing is embedded in one side of the end cap;

[0011] A collar, fixed inside the inner ring of the bearing, is rotated and supported.

[0012] The inclined wheel is set inside the collar by a translation adjustment component, and the part of the inclined wheel away from the heat exchange tube has an inclined surface.

[0013] Furthermore, the translation adjustment component includes:

[0014] T-grooves are symmetrically formed on the inner wall of the collar along the collar axis;

[0015] The T-blocks are symmetrically arranged on the outside of the inclined wheel, located away from the tilt angle, and extend to the inside of the T-guide groove for sliding engagement.

[0016] Through bolts, symmetrically threaded through one end of the collar, with the end extending to the inside of the T-slot and rotatably connected to the T-block.

[0017] Furthermore, the insertion device includes:

[0018] The insert rod passes through the center of the swashplate and is threaded to the inner wall of the swashplate.

[0019] One end of the insertion rod is sharp and extends to the inside of the end tube, and is aligned with the heat exchange tube at the corresponding position;

[0020] Multiple rubber rings are embedded and fixed at the other end of the end cap, corresponding to the position of the inclined wheel, and are sleeved on the outside of the insertion rod;

[0021] A groove, circularly formed on one side of the rubber ring;

[0022] The ring is fixed to the outside of the insertion rod, with one side of the outer wall having an inclined angle and the other side extending towards the groove so as to fit into the groove.

[0023] Furthermore, the drive connector includes:

[0024] The motor is fixed above the end cylinder;

[0025] The speed reducer is connected to the drive end of the motor and is also connected to the end cover.

[0026] The T-roller is installed at the drive end of the reducer;

[0027] The adjusting parts are located below the T-roller and are rotatably connected to the end cover.

[0028] Furthermore, the adjusting component includes:

[0029] A multi-stage electric rod, one end of which is rotatably connected to the end cover and located below the T-roller;

[0030] Connecting plate, attached to the telescopic end of the multi-stage electric pole;

[0031] The inclined rubber wheel is rotatably mounted on one side of the connecting plate;

[0032] The T-wheel is fixed to one end of the inclined rubber wheel;

[0033] The belt component is fitted onto the outside of the T-roller and T-wheel.

[0034] Furthermore, the belt component includes:

[0035] The belt is wrapped around the outside of the T-roller and T-pulley;

[0036] Buckle, fixed to one end of the belt;

[0037] The other end of the belt passes through the buckle in an S-shape and is inserted;

[0038] Multiple hoops are evenly distributed on the outer side of the belt to secure the other end of the belt.

[0039] Furthermore, the regulating component includes:

[0040] The support block, made of rubber, is fixed to the outside of the motor;

[0041] Screw, through-bracing block friction connection;

[0042] The limiting grooves are symmetrically opened on the outside of the screw and the insert.

[0043] The above-described solution of the present invention has at least the following beneficial effects:

[0044] By setting up a blockage-clearing section and a drive adjustment section, the heat exchange tubes can be unblocked and the inner wall dirt can be cleaned without disassembling the condenser. This allows operators to selectively unblock specific blocked heat exchange tubes without completely shutting down the machine for disassembly, thus realizing the condensation and heat exchange of high-temperature gaseous refrigerant. This solves the problems of decreased refrigeration efficiency, the need for machine shutdown, and increased energy consumption caused by heat exchange tube blockage in the refrigeration system.

[0061] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0062] like Figures 1 to 14 As shown, an embodiment of the present invention provides a direct-cooling cryogenic condenser, including a condenser shell 1 and end cylinders 2 fixed to both ends of the condenser shell 1. The ends of the end cylinders 2 are connected to end caps 3 via fixing components. Support plates 5 are symmetrically arranged on the inner side of the condenser shell 1. Multiple heat exchange tubes 4 are uniformly arranged through the interior of the support plates 5. Multiple partition plates 6 are spaced apart on the outer side of the heat exchange tubes 4. The condenser shell 1 also includes:

[0063] The unblocking section is sealed by the through end cap 3 and corresponds to the position of each heat exchange tube 4. It includes an adjusting support that rotates one end of the through end cap 3 to provide adjustment and rotational support, and a threaded through adjusting support for sealing or inserting into the heat exchange tube 4 to unblock the blockage.

[0064] The adjustment drive unit is located on the outside of the end cylinder 2 and extends to one side of the end cover 3. It includes a drive connector fixed on the end cylinder 2 for providing driving force, and an adjustment drive unit located on one side of the drive connector for adjusting the position to drive the adjustment support.

[0065] Specifically, the condenser shell 1 provides stable support for the end cylinder 2, the end cylinder 2 can be securely supported by bolts for the end cover 3, the end cover 3 can cover the opening of the end cylinder 2, and the condenser shell 1 can provide support and a through passage for multiple heat exchange tubes 4 through the support plate 5, so that the heat exchange tubes 4 can provide support for the partition plate 6, such as... Figure 2 As shown, the partition plate 6 can provide a drift barrier and guide for the high-temperature gaseous refrigerant, prolonging the contact time between the gas and the heat exchange tube 4. The heat exchange tube 4 can provide a flow channel for the cooling medium, and is made of copper with good thermal conductivity, which can transfer the heat in the gas to the cooling medium, thereby cooling the high-temperature gaseous refrigerant, causing the high-temperature gaseous refrigerant to condense into a liquid state, and fall into the second flange 10 for discharge by gravity.

[0066] In practical application, the operator can connect the pipeline for conveying the cooling medium to the inlet flange 7 and the outlet flange 8, allowing the cooling medium to enter the end cylinder 2 on one side, pass through the end cylinder 2 into each heat exchange tube 4, then pass through the heat exchange tube 4 into the end cylinder 2 on the other side, and be discharged from the outlet flange 8. The operator can also connect the pipeline for conveying the refrigerant to the first flange 9 and the second flange 10, allowing the high-temperature gaseous condensate to enter the first flange 9, pass through the first flange 9 into the condenser shell 1, and contact the heat exchange tube 4 to condense into a low-temperature liquid condensate. Under gravity, the liquid condensate falls into the inner bottom wall of the condenser shell 1, simultaneously flowing into the inside of the second flange 10 and being discharged through the second flange 10 (for use).

[0067] In a preferred embodiment of the present invention, the adjusting support includes:

[0068] Bearing 11 is embedded on one side of end cover 3;

[0069] The collar 12 is fixed to the inner side of the inner ring of the bearing 11 so as to be rotatably supported;

[0070] The inclined wheel 13 is set inside the collar 12 by a translation adjustment component, and the part of the inclined wheel away from the heat exchange tube has an inclined surface.

[0071] Specifically, the end cap 3 can provide stable support for the bearing 11, the bearing 11 can provide rotational support for the collar 12, the collar 12 can provide translational space and through channel for the inclined wheel 13, and the inclined wheel 13 has an inclined angle so that it can easily contact the inclined rubber wheel 28 and be driven by the inclined rubber wheel 28.

[0072] The translation adjustment components include:

[0073] T-grooves 14 are symmetrically formed on the inner wall of the collar 12;

[0074] T-block 15 is symmetrically arranged on the outside of the inclined wheel 13 and located away from the tilt angle, and extends to the inner side of the T-guide groove 14 for sliding engagement;

[0075] Through bolt 16, symmetrically through one end of collar 12 is threaded, and the end extends to the inner side of T guide groove 14 and is rotatably connected to T block 15.

[0076] Specifically, the collar 12 provides space for the T-guide groove 14, the T-guide groove 14 provides a moving guide for the T-block 15, the T-block 15 provides a sliding guide for the inclined wheel 13, the T-guide groove 14 provides rotational and moving space for the through bolt 16, the T-block 15 provides rotational support for the through bolt 16, and the through bolt 16 can use rotational power and the thread action with the collar 12 to pull the T-block 15 to translate along the T-guide groove 14.

[0077] The encrypted file includes:

[0078] The insert rod 17 passes through the center of the inclined wheel 13 and is threaded to the inner wall of the inclined wheel 13;

[0079] One end of the insertion rod 17 is sharp and extends to the inside of the end tube 2, and is aligned with the heat exchange tube 4 at the corresponding position;

[0080] Multiple rubber rings 18 are embedded and fixed at the other end of the end cap 3, corresponding to the position of the inclined wheel 13, and are sleeved on the outside of the insertion rod 17;

[0081] The groove 19 is circumferentially formed on one side of the rubber ring 18;

[0082] The ring 20 is fixed to the outside of the insert rod 17, and one side of the outer wall has an inclined angle, while the other side extends towards the groove 19 and can be matched with the groove 19.

[0083] Specifically, the inclined wheel 13 provides threaded support for the insertion rod 17, which in turn provides stable support for the ring 20. The insertion rod 17 can be inserted into the blockage in the heat exchange tube 4 with its sharp end, and the blockage can be cleared by agitating the blockage during rotation. The end cap 3 provides stable support for the rubber ring 18, which is made of rubber and provides space for the groove 19. The groove 19 can cooperate with the side of the ring 20 near the rubber ring 18, so that the rubber ring 18 and the ring 20 cooperate with the insertion rod 17 to form a seal and prevent liquid in the end tube 2 from entering the collar 12.

[0084] In practical application, the number of insertion rods 17 is the same as the number of heat exchange tubes 4, and their positions correspond. Operators can rotate the through bolts 16 as needed, causing the through bolts 16 to push the T-block 15 along the T-guide groove 14 towards the heat exchange tube 4 using the threaded action with the collar 12. This allows the inclined wheel 13, which might interfere with the adjustment and drive section, to move into the inner side of the collar 12 and be stored under the drive of the T-block 15 (e.g., ...). Figure 4 As shown), to avoid a collar 12 that is not currently in use affecting the movement operation of the drive unit, the operator can then rotate the through bolt 16 at the position corresponding to the heat exchange tube 4 that needs to be cleared, so that the through bolt 16, through the thread action with the collar 12, drives the T block 15 at that position to move along the T guide groove 14 in a direction away from the heat exchange tube 4, so that the T block 15 can drive the inclined wheel 13 to move together, so that the inclined surface of the inclined wheel 13 can be moved from the inside to the outside of the collar 12 so as to contact and cooperate with the inclined rubber wheel 28.

[0085] Before the direct-cooling cryogenic heat exchanger needs to be put into operation, the operator needs to rotate the through bolt 16 to move the inclined wheel 13 away from the heat exchange tube 4 by using the thread action with the collar 12. The inclined wheel 13 drives the insertion rod 17 to move together, and then the insertion rod 17 can drive the ring 20 to move closer to the rubber ring 18 until the rotation and movement of the through bolt 16 is blocked. At this time, the ring 20 is in a state of close fit with the rubber ring 18 inside the insertion groove 19, thereby playing a sealing role. Then the direct-cooling cryogenic heat exchanger can be put into operation.

[0086] As a preferred embodiment of the present invention, the drive connector includes:

[0087] Motor 21 is fixed above end cylinder 2;

[0088] The reducer 24 is connected to the drive end of the motor 21 and is also connected to the end cover 3;

[0089] T-roller 25 is installed at the drive end of reducer 24;

[0090] The adjusting parts are located below the T roller 25 and are rotatably connected to the end cover 3.

[0091] Specifically, the motor 21 can drive the reducer 24 with the support of the end cylinder 2. The reducer 24 can reduce the rotation speed and drive the T roller 25 to rotate at a low speed with the drive end.

[0092] Adjustment parts include:

[0093] The multi-stage electric rod 26 is rotatably connected to the end cover 3 at one end and is located below the T roller 25;

[0094] Connecting plate 27 is connected to the telescopic end of multi-stage electric pole 26;

[0095] The inclined rubber wheel 28 is rotatably mounted on one side of the connecting plate 27;

[0096] T-wheel 29 is fixed at one end of inclined rubber wheel 28;

[0097] The belt 30 sub-part is sleeved on the outside of the T roller 25 and T wheel 29.

[0098] Specifically, the end cap 3 can provide rotational support for the multi-stage electric rod 26, the multi-stage electric rod 26 can provide support for the connecting plate 27 and can drive the connecting plate 27 to rotate together, the connecting plate 27 can provide rotational support for the inclined rubber wheel 28, the T wheel 29 can drive the inclined rubber wheel 28 to rotate using external force, and the inclined rubber wheel 28 can fit with the inclined surface of the inclined wheel 13 and drive the inclined wheel 13 to rotate using rotational power when it fits with the inclined wheel 13.

[0099] The belt 30 sub-components include:

[0100] The belt 30 is wrapped around the outside of the T-roller 25 and the T-wheel 29;

[0101] Buckle 31 is fixed to one end of belt 30;

[0102] The other end of the belt 30 passes through the buckle 31 in an S-shape and is inserted;

[0103] Multiple loops 32 are evenly distributed on the outside of the belt 30 to secure the other end of the belt 30.

[0104] Specifically, the belt 30 can form a ring structure with buckle 31 and hoop 32 and be fitted on the outside of T roller 25 and T wheel 29, and transmit rotational power by friction. The belt 30 can also be adjusted by the buckle 31 and hoop 32 under the operation of the operator to adapt to the driving needs at different positions.

[0105] The adjustment components include:

[0106] Support block 22, made of rubber, is fixed to the outside of motor 21;

[0107] Screw 23, through support block 22 friction connection;

[0108] The limiting groove 33 is symmetrically opened on the outside of the screw 23 and the insert 17;

[0109] Support plate 34 is symmetrically fixed to one end of inclined wheel 13;

[0110] Screw 35, with threads passing through support plate 34, extends into limiting groove 33;

[0111] The scraping parts are set through the insert rod 17 and the screw rod 23.

[0112] Specifically, the support block 22 can provide a through channel and support for the screw 23 under the support of the motor 21, making it convenient to store the screw 23. The screw 23 can provide opening space for the limiting groove 33, and the screw 23 can be snapped into the insert rod 17 at one end. The inclined wheel 13 can stably support the support plate 34. The support plate 34 can provide thread support for the screw 35. The screw 35 can cooperate with the limiting groove 33 to prevent the screw 23 from rotating.

[0113] The scraping parts include:

[0114] The round-headed rod 36 is connected to the threaded rod 23 and is located at the axial position;

[0115] The circular plate 37 is fixed to the end of the round-headed rod 36 away from the insertion rod 17;

[0116] The rubber sleeve 38 is installed above and below the insertion rod 17;

[0117] The inclined blade 39 is located inside the insert rod 17 and extends into the rubber sleeve 38;

[0118] The inclined blade 39 has an inclined angle on the side near the round head rod 36;

[0119] The elastic plate 40 is connected at one end to the inclined plate blade 39 and at the other end to the inner wall of the insertion rod 17.

[0120] Specifically, screw 23 provides movable support for round-headed rod 36, screw 23 provides support for round plate 37, round plate 37 facilitates the movement of round-headed rod 36 by workers, insert rod 17 provides stable support for rubber sleeve 38, rubber sleeve 38 is made of rubber and can use elasticity to push the inclined blade 39, elastic plate 40 can use rebound force under the support of insert rod 17 to push the inclined blade 39 to overcome the friction with rubber sleeve 38 and move back to its original position. Figure 4 At the location shown.

[0121] In practical application, after the operator adjusts the position of the inclined rubber wheel 28 to contact the inclined wheel 13 at the desired position of the protruding collar 12, and simultaneously adjusts the belt 30, the screw 23 needs to be pulled out through the support block 22 and removed. One end of the screw 23 is then snapped into one end of the insertion rod 17. After that, the motor 21 is started, and the motor 21, together with the belt 30, T roller 25, and T wheel 29, drives the inclined rubber wheel 28 to rotate under the support of the connecting plate 27. The inclined rubber wheel 28 uses rotational power and friction to push the inclined wheel 13 to rotate. At the same time, the inclined wheel 13 will drive the collar 12 to rotate together under the support of the bearing 11 through the T block 15. The inclined wheel 13 can use rotational power and thread action, along with the guiding and limiting action of the screw 35 and the limiting groove 33, to push the insertion rod 17 and the screw 23 to continuously move and insert into the heat exchange tube 4 at the current position. During the insertion process, the blockage and disturbance in the heat exchange tube 4 are cleared.

[0122] The operator can determine the position of the insertion rod 17 inside the heat exchange tube 4 based on the length of the screw 23 extending into the end cylinder 2. Depending on the actual needs, after the insertion rod 17 moves the inclined plate 39 to the appropriate position, the operator can loosen the screw 35, causing it to move out of the limiting groove 33. Then, the round plate 37 pushes the round-headed rod 36, causing it to move towards the sharp end of the insertion rod 17 under the support of the screw 23. This allows the round-headed rod 36 to use external force and its own arc-shaped head, combined with the tilt angle of the inclined plate 39, to push the inclined plate 39 through the rubber sleeve 38 towards the inner wall of the heat exchange tube 4. Simultaneously, the inclined plate 39 will compress the elastic force. The plate 40 stores energy, and the round-headed rod 36 provides a supporting barrier for the inclined blade 39, allowing the sharp end of the inclined blade 39 to make slight contact with the inner wall of the heat exchange tube 4. Then, the motor 21 is started, which drives the inclined rubber wheel 28, which is in contact with the inclined wheel 13, to rotate. The inclined rubber wheel 28 uses rotational power to drive the inclined wheel 13 to rotate under the support of the bearing 11. At the same time, the inclined wheel 13 uses the friction of the threaded connection to drive the insert rod 17 to rotate together. The insert rod 17 can drive the screw 23, the inclined blade 39, and the elastic plate 40 to rotate together. Thus, the inclined blade 39 and the elastic plate 40 can be used in combination with the rotational power to scrape off the stubborn stains adhering to the inner wall of the heat exchange tube 4.

[0123] The operator can pull the round-headed rod 36 outward to separate it from the inclined blade, thereby eliminating the obstruction and support of the inclined blade, and allowing the elastic plate 40 to use its rebound force to push the inclined blade back to its original position.

[0124] In another embodiment (where the inclined wheels 13 are all in the state of extending out of the collar 12 on the inclined surface, and the groove 19 is in the state of engaging with the ring 20), the operator can connect the T-roller 25 to the drive end of the reducer 24 via the electric telescopic rod 41, and rotatably connect the fixed end of the multi-stage electric rod 26 to the end cover 3 via the electric telescopic rod 41. The two electric telescopic rods 41 are set to achieve synchronous extension and retraction, allowing the operator to adjust the T-roller 25 and the multi-stage electric rod simply by controlling the extension of the electric telescopic rod 41. At position 26, the multi-stage electric rod 26 will drive the inclined rubber wheel 28 and T wheel 29 to move together through the connecting plate 27, so that the T roller 25 and T wheel 29 can move synchronously to the side away from the end cover 3. This achieves the goal of avoiding interference with the adjustment and movement of the drive unit even when the inclined wheel 13 is moved into the inner side of the collar 12 without adjustment. After the T wheel 29 and inclined rubber wheel 28 are adjusted and moved to the appropriate position, the electric telescopic rod 41 can be controlled to retract and reset, so that the inclined rubber wheel 28 can contact the inclined wheel 13 at the corresponding position.

[0125] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
