Description

Technical Field

[0001] This utility model relates to the field of tubular evaporator technology, and in particular to a tubular evaporator that is easy to disassemble and maintain. Background Technology

[0002] A tubular evaporator is a type of indirect heat exchanger in which liquid refrigerant flows and evaporates inside or outside the tubes, absorbing heat from another medium inside or outside the tubes through the tube walls, thereby achieving the purpose of refrigeration. Simply put, it is a device that uses the principle of refrigerant boiling and absorbing heat to cool other substances. Its core feature is the use of the piping system as a heat transfer surface between two fluids. The tubular evaporator is a key component in the refrigeration system responsible for "generating cooling capacity". It continuously absorbs heat from the surrounding environment by allowing the refrigerant to evaporate in a closed piping system.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: The main difficulty faced by existing traditional tubular evaporators during maintenance lies in their bolt-fixed installation method. After long-term operation, these bolts are very prone to corrosion and seizing due to water vapor and alternating hot and cold temperatures. When disassembling, maintenance personnel need to handle them one by one in a narrow space, which often takes a lot of time. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing tubular evaporator is not easy to disassemble and maintain. Therefore, we propose a tubular evaporator that is easy to disassemble and maintain.

[0005] To achieve the above objectives, this application adopts the following technical solution: a tubular evaporator that is easy to disassemble and maintain, comprising a tubular evaporator body, an mounting plate provided on the back of the tubular evaporator body, T-blocks fixedly connected to both sides of the back of the tubular evaporator body, a limiting block slidably connected to the surface of the T-block, the back of the limiting block being fixedly connected to both sides of the front of the mounting plate, an installation assembly provided on the inner side of the limiting block, the installation assembly including a double-headed motor, the double-headed motor being located at the center of the front of the mounting plate, a drive screw fixedly connected to the output end of the double-headed motor, a fixing sleeve threadedly connected to the surface of the drive screw, and a positioning block fixedly connected to the outer side of the fixing sleeve.

[0006] Preferably, a positioning hole is provided on the inner side of the limiting block, and the positioning block is located inside the positioning hole.

[0007] Preferably, a bearing is movably sleeved at the center of the surface of the drive screw, and the back of the bearing is fixedly connected to the front of the mounting plate.

[0008] Preferably, a movable block is fixedly connected to the top of the fixed screw sleeve, and a fixed block is slidably connected to the top of the movable block, with the back of the fixed block located on the front of the mounting plate.

[0009] Preferably, a support plate is fixedly connected to the bottom of the dual-head motor, and the back of the support plate is fixedly connected to the center of the front of the mounting plate.

[0010] Preferably, mounting holes are provided around the front of the mounting plate, and handles are fixedly connected to both sides of the front of the tubular evaporator body.

[0011] The technical effects and advantages of this utility model are as follows: In this invention, by setting up components such as a T-block, a limiting block, a dual-head motor, and a drive screw, the dual-head motor can be started. The output end of the dual-head motor rotates, causing the drive screw to rotate inside the bearing. The rotation of the drive screw causes the fixing sleeve to move inward, which in turn causes the positioning block to move outward. The outward movement of the positioning block cancels the limiting effect on the T-block.

[0012] In this invention, the positioning hole allows the positioning block to slide inside, thus limiting or releasing the T-shaped block. Attached Figure Description

[0015] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0016] Reference Figures 1-4 As shown, this utility model provides a technical solution: a tubular evaporator that is easy to disassemble and maintain, including a tubular evaporator body 1, an installation plate 2 provided on the back of the tubular evaporator body 1, T-shaped blocks 3 fixedly connected to both sides of the back of the tubular evaporator body 1, a limiting block 4 slidably connected to the surface of the T-shaped block 3, the back of the limiting block 4 being fixedly connected to both sides of the front of the installation plate 2, an installation component 5 provided on the inner side of the limiting block 4, the installation component 5 including a double-headed motor 6, the double-headed motor 6 being located at the center of the front of the installation plate 2, a drive screw 7 fixedly connected to the output end of the double-headed motor 6, a fixing sleeve 8 threadedly connected to the surface of the drive screw 7, and a positioning block 9 fixedly connected to the outer side of the fixing sleeve 8.

[0017] Specifically: By setting up components such as T-block 3, limit block 4, dual-head motor 6 and drive screw 7, the dual-head motor 6 can be started. The output end of the dual-head motor 6 rotates, driving the drive screw 7 to rotate inside the bearing 11. The rotation of the drive screw 7 drives the fixing sleeve 8 to move inward, driving the positioning block 9 to move outward. The outward movement of the positioning block 9 cancels the limit on the T-block 3.

[0018] Reference Figure 4 As shown in this embodiment: a positioning hole 10 is provided on the inner side of the limiting block 4, and the positioning block 9 is located inside the positioning hole 10.

[0019] Specifically: By setting the positioning hole 10, the positioning block 9 can slide inside through the positioning hole 10 to limit or release the T-shaped block 3.

[0020] Reference Figure 3 As shown in this embodiment: a bearing 11 is movably sleeved at the center of the surface of the drive screw 7, and the back of the bearing 11 is fixedly connected to the front of the mounting plate 2.

[0021] Specifically, the bearing 11 provides crucial radial limiting and rigid support for the drive screw 7 through precise positioning. This component transforms the potential sliding friction of the drive screw 7 during rotation into efficient rolling friction. When it is subjected to radial load or high-speed operation, the bearing 11 can effectively constrain and absorb its multi-directional stress, thereby significantly suppressing the possible swaying, vibration and wobbling of the screw.

[0022] Reference Figure 3As shown in this embodiment: a movable block 12 is fixedly connected to the top of the fixed screw sleeve 8, a fixed block 13 is slidably connected to the top of the movable block 12, and the back of the fixed block 13 is located on the front of the mounting plate 2.

[0023] Specifically, by setting the moving block 12 and the fixed block 13, the fixed screw sleeve 8 can be limited to prevent the driving screw 7 from rotating on its surface during operation, thus affecting the normal sliding of the positioning block 9.

[0024] Reference Figure 2 As shown in this embodiment: the bottom of the dual-head motor 6 is fixedly connected to a support plate 14, and the back of the support plate 14 is fixedly connected to the center of the front of the mounting plate 2.

[0025] Specifically, by adding a support plate 14, a key and reliable auxiliary support and fixation is provided for the dual-head motor 6. This structure effectively makes up for the lack of fixation that may exist when the motor is installed by the main shaft alone, and significantly improves the overall stability of the equipment during operation. When the dual-head motor 6 starts, changes speed or bears a load, the support plate 14 can effectively suppress the radial sway and vibration that may be generated, ensuring that the power transmission is more stable and precise.

[0026] Reference Figure 1 As shown in this embodiment: mounting holes 15 are provided around the front of the mounting plate 2, and handles 16 are fixedly connected to both sides of the front of the tubular evaporator body 1.

[0027] Specifically: the mounting hole 15 makes it easy for users to fix the device to the wall, and the handle 16 makes it easy for users to remove the tubular evaporator body 1 from inside the limiting block 4.

[0028] Working principle: When it is necessary to disassemble and maintain the tubular evaporator body 1, the operator only needs to start the dual-head motor 6. The output end of the motor starts to rotate, driving the two drive screws 7 to rotate synchronously under the support of the bearing 11. The rotation of the drive screws 7 is converted into the linear motion of the fixed screw sleeve 8, which smoothly retracts towards the center. This action, through mechanical linkage, drives the positioning blocks 9 on both sides to retract outward, thereby releasing their locking limit on the T-shaped block 3 and completing the automatic disengagement of the locking mechanism. Subsequently, the operator can directly grasp the handle 16 and lift the tubular evaporator body 1 vertically upward from the guide structure of the limiting block 4, easily removing it. This achieves quick and labor-saving separation, providing great convenience for subsequent maintenance work.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
