Description

Technical Field

[0001] This invention relates to the field of flake ice machine technology, and more specifically, to a high-efficiency and energy-saving evaporator for flake ice machines. Background Technology

[0002] As a core ice-making equipment in food refrigeration, aquatic product processing, and chemical cooling, the evaporator of a flake ice machine is a key component for achieving refrigeration and ice making. The precise temperature control of the evaporator directly determines the ice-making efficiency, ice layer formation quality, and overall energy consumption. Currently, most conventional flake ice machine evaporators on the market use external temperature probes to monitor the temperature in real time. The evaporator controls the start and stop of the refrigeration system and the refrigerant flow based on the temperature data fed back by the probe, thereby maintaining a stable ice-making condition and ensuring continuous flake ice production. In existing technologies, temperature probes are generally fixed in place, directly attached to a single point on the outer wall of the evaporator. They obtain local temperature signals through close contact with the outer wall of the evaporator. However, during continuous ice-making operation, the evaporator is affected by factors such as uneven refrigerant distribution, differences in water flow rate, and varying ice layer thickness, resulting in significant temperature gradients at different locations on its outer wall, rather than a uniform and constant temperature state. However, fixed, single-point temperature probes can only detect the local temperature at their specific location and cannot fully cover the overall temperature distribution of the evaporator. This easily leads to problems such as distorted and delayed temperature detection data. Local temperature data cannot accurately reflect the overall cooling status of the evaporator. At best, this can cause frequent false starts and stops of the refrigeration system and refrigerant supply imbalances, significantly increasing overall energy consumption and reducing ice-making efficiency. At worst, it can cause localized overcooling and ice blockage, or localized insufficient cooling and uneven ice formation, affecting the quality of flake ice, shortening the evaporator's lifespan, and failing to meet the current demand for efficient, energy-saving, and stable operation of flake ice machines.

[0005] Preferably, a disassembly block with one end extending into the disassembly slot is fixedly installed on the side wall of the temperature probe facing the disassembly slot. The assembly / disassembly assembly includes a screw located on the upper surface of the assembly / disassembly plate, with the lower end of the screw threaded through the assembly / disassembly plate.

[0006] Preferably, the buffer assembly includes a connecting block slidably placed in the buffer cavity, a connecting plate connected to the disassembly plate is fixedly installed on the side wall of the connecting block facing the disassembly plate, a blocking plate for the connecting plate to pass through is fixedly installed at the opening of the buffer cavity, and a spring for pushing the connecting plate to move towards the blocking plate is placed in the buffer cavity.

[0007] Preferably, the drive assembly includes two threaded rods rotatably mounted on one side wall of the lifting block. One end of the threaded rod is threaded through the moving plate, and the ends of the two threaded rods away from the moving plate are threaded through the lifting block. A first synchronous pulley is fixedly sleeved on the through end of each threaded rod, and a first synchronous belt is sleeved between the two first synchronous pulleys. The side wall of the lifting block away from the moving plate is provided with a rotating component for driving one of the two threaded rods to rotate.

[0008] Preferably, a first gear is fixedly sleeved on the side wall of the threaded rod away from the lifting block; The rotating component includes a bracket, which is fixedly installed on the side wall of the lifting block away from the moving plate. A motor is fixedly installed on the side wall of the bracket away from the moving plate. The output shaft of the motor passes through the bracket and is fixedly sleeved on a second gear that meshes with the first gear.

[0009] Preferably, a limiting plate is fixedly installed inside the mounting frame, and a limiting rod that is opposite to and passes through the lifting block is fixedly installed between the limiting plate and the lower side of the mounting frame; The lifting assembly is rotatably mounted on the upper end face of the base frame, and the lifting rod is threaded through the lifting block.

[0010] Preferably, the lower end of the lifting rod passes through the base frame, and a second synchronous wheel is fixedly sleeved on the through end of the lifting rod. A round rod is rotatably installed on the upper surface of the base frame, and the lower end of the round rod passes through the base frame. A third synchronous wheel is fixedly sleeved on the through end of the round rod, and a second synchronous belt is sleeved between the second synchronous wheel and the third synchronous wheel.

[0011] Preferably, the upper end face of the base frame has multiple insertion holes along the circumference of the round rod, the round rod above the base frame has a groove, the round rod above the base frame is slidably fitted with an insertion plate, the inner side wall of the insertion plate has a protrusion that is inserted into the groove, the lower end face of the insertion plate is fixedly fitted with multiple insertion rods, and the round rod above the base frame is threaded with a nut.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the coordinated operation of the lifting and driving components, enables dynamic multi-point detection of temperature probes on the outer wall of the evaporator. It can accurately capture the temperature gradient formed by differences in refrigerant distribution, water flow velocity, and ice layer thickness during equipment operation, fundamentally avoiding the problems of temperature detection data distortion and lag. This design allows the temperature measurement data to truly reflect the overall refrigeration condition of the evaporator, avoiding erroneous start-up and shutdown of the refrigeration system due to local temperature misjudgment, accurately matching the actual refrigeration needs of the evaporator, effectively solving the core problems of increased energy consumption and decreased ice-making efficiency caused by inaccurate temperature measurement in the prior art, and significantly improving the accuracy of equipment operation.

[0013] 2. This invention, through the inclusion of a buffer component, achieves elastic contact between the temperature probe and the outer wall of the evaporator, completely avoiding the component damage problems caused by traditional hard contact. The spring and connecting block inside the buffer cylinder form a flexible buffer structure. When the drive component pushes the temperature probe close to the evaporator, the spring effectively buffers the impact force at the moment of contact, transforming the hard collision into a smooth elastic contact. This design not only avoids damage and malfunction of the temperature probe caused by frequent hard contact, extending the service life of the temperature measuring component, but also ensures that the temperature probe always maintains a tight and stable contact with the outer wall of the evaporator, ensuring the continuity and accuracy of the temperature measurement signal, reducing the frequency of equipment downtime for maintenance due to probe damage, and guaranteeing the continuous operation of the flake ice machine.

[0014] 3. This invention significantly reduces the difficulty of inspecting and replacing temperature measuring components through the cooperation of the disassembly and assembly components and the lifting components. When maintenance of the temperature probe is required, the drive component can move the probe away from the evaporator, and the lifting component can then lower it to the lowest position. The operator only needs to turn the screw to quickly release the limit of the disassembly and assembly block and remove the probe. After maintenance, the reverse operation can be performed to achieve precise installation. This design does not require disassembly of the evaporator or other core components, eliminating the cumbersome disassembly and assembly procedures in traditional maintenance, shortening equipment downtime for maintenance, reducing the technical requirements for operators, and making daily maintenance and component replacement more efficient and convenient, further improving the operation and maintenance efficiency of the flake ice machine.

[0015] 4. This invention achieves highly efficient and energy-saving operation of the flake ice machine through precise temperature control and operational optimization, meeting the current demand for energy conservation and consumption reduction in industrial equipment. Relying on accurate data obtained from multi-point dynamic temperature measurement, the refrigeration system can adjust the refrigerant flow and start / stop status as needed, avoiding energy waste caused by refrigerant supply imbalance and frequent system start / stop due to inaccurate temperature measurement. At the same time, the uniform cooling state of the evaporator makes the ice-making process more efficient. While ensuring flake ice production, it significantly reduces the overall power and refrigerant consumption of the machine. In addition, the extended service life of components also reduces the material consumption for equipment replacement parts. It achieves energy-saving benefits in terms of both operating energy consumption and maintenance costs, and improves the economic applicability of the equipment. Attached Figure Description

[0027] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0028] The following is in conjunction with the appendix Figures 1-10 This embodiment will be described in further detail.

[0029] This embodiment of a high-efficiency and energy-saving evaporator for a flake ice machine includes a base plate 10, an evaporator 11 fixedly mounted on the upper end face of the base plate 10, a base frame 12 fixedly mounted on the upper end face of the base plate 10, an mounting frame 13 fixedly mounted on the upper end face of the base frame 12, a lifting block 25 provided inside the mounting frame 13, a disassembly plate 16 provided on the lifting block 25 facing the evaporator 11, a disassembly groove for installing a temperature probe 18 opened on the side wall of the disassembly plate 16 facing the evaporator 11, and a disassembly assembly for limiting the temperature probe 18 in the disassembly groove on the upper end face of the disassembly plate 16. A movable plate 14 is provided between the lifting block 25 and the disassembly plate 16. A buffer cylinder 21 is fixedly installed on the side wall of the movable plate 14 facing the disassembly plate 16. A buffer cavity with an opening facing the disassembly plate 16 is provided in the buffer cylinder 21. A buffer assembly for protecting the temperature probe 18 is provided in the buffer cavity. The lifting block 25 is provided with a drive assembly on the side wall facing the moving plate 14 for driving the moving plate 14 to move. The upper end face of the base frame 12 is provided with a lifting assembly for driving the lifting block 25 to rise and fall.

[0030] In this embodiment, the evaporator 11 is connected to the flake ice machine. When the evaporator 11 is in use, the drive assembly on the lifting block 25 will drive the moving plate 14 to move toward the evaporator 11. At this time, the moving plate 14 can drive the disassembly plate 16 to move through the buffer cylinder 21. The movement of the disassembly plate 16 drives the temperature probe 18 to abut against the outer wall of the evaporator 11. At this time, the temperature probe 18 can detect the temperature of the working evaporator 11. When the temperature probe 18 comes into contact with the outer wall of the evaporator 11, the temperature probe 18 will make hard contact with the evaporator 11, which may damage the temperature probe 18. In order to avoid this situation, when the temperature probe 18 contacts the outer wall of the evaporator 11, the buffer assembly in the buffer cylinder 21 will buffer the disassembly plate 16, so that the hard contact between the temperature probe 18 and the evaporator 11 becomes an elastic contact, thereby avoiding the damage to the temperature probe 18 caused by the hard contact between the temperature probe 18 and the evaporator 11. When the temperature probe 18 contacts the side wall of the evaporator 11, the lifting block 25 is driven to rise and fall by the lifting assembly, so that the lifting block 25 can rise and fall within the base frame 12. The rising and falling lifting block 25 can drive the moving plate 14 to rise and fall. The rising and falling moving plate 14 can drive the disassembly plate 16 to rise and fall through the buffer cylinder 21. The rising and falling of the disassembly plate 16 drives the temperature probe 18 to rise and fall, so that the temperature probe 18 abuts against the outer wall of the evaporator 11 at different positions. Compared with the existing ones, this kind of high-efficiency and energy-saving evaporator of the flake ice machine can realize the dynamic detection of the temperature probe 18 at multiple points on the outer wall of the evaporator 11 in actual use, effectively solving the problems of single-point temperature measurement distortion and lag, truly reflecting the overall refrigeration status, improving ice-making efficiency and ice layer uniformity, reducing energy consumption and extending the service life of the evaporator 11. When the evaporator 11 stops working, the drive assembly drives the moving plate 14 to move towards the lifting block 25. The moving plate 14 can drive the disassembly plate 16 to move through the buffer cylinder 21. The movement of the disassembly plate 16 can drive the temperature probe 18 away from the evaporator 11, so that the temperature probe 18 can stop detecting the temperature of the evaporator 11. When the temperature probe 18 is away from the evaporator 11, the lifting assembly drives the lifting block 25 to move down to the lowest position. At this time, the lifting block 25 can drive the disassembly plate 16 to move down to the lowest position through the moving plate 14. The disassembly plate 16 then drives the temperature probe 18 to move down to the lowest position. At this time, the temperature probe 18 can be removed from the disassembly slot through the disassembly assembly, which is convenient for replacing and repairing the temperature probe 18. After the replacement and repair of the temperature probe 18 are completed, the temperature probe 18 can be installed in the disassembly plate 16 through the disassembly assembly. Among them, the high-efficiency and energy-saving evaporator of the ice machine achieves multiple points of elastic contact detection of temperature probe 18 on the outer wall of evaporator 11 through the cooperation of lifting component and drive component, avoiding hard damage, and making the temperature measurement accurate and comprehensive. At the same time, it is easy to disassemble and maintain the probe, effectively improving ice-making efficiency, reducing energy consumption, and ensuring stable and long-term operation of the equipment.

[0031] In this embodiment, a disassembly block with one end extending into the disassembly slot is fixedly installed on the side wall of the temperature probe 18 facing the disassembly slot. The assembly / disassembly assembly includes a screw 19 located on the upper end face of the assembly / disassembly plate 16, with the lower end of the screw 19 threaded through the assembly / disassembly plate 16.

[0032] In this embodiment, the temperature probe 18 is installed in the disassembly slot by inserting the disassembly block into the disassembly slot. At this time, the bolt is inserted from the upper end face of the disassembly plate 16, and the screw 19 is rotated and moved downward. The downward-moving screw 19 can be inserted into the disassembly block, thereby realizing the installation of the disassembly block in the disassembly slot, that is, the temperature probe 18 is installed on the disassembly plate 16. By rotating the screw 19, the screw 19 moves upward, and the lower end of the screw 19 slides out of the disassembly block. At this time, the installation of the disassembly block in the disassembly slot is released, that is, the installation of the temperature probe 18 on the disassembly plate 16 is released.

[0033] In this embodiment, the buffer assembly includes a connecting block 30 that is slidably placed in the buffer cavity. A connecting plate 32 connected to the disassembly plate 16 is fixedly installed on the side wall of the connecting block 30 facing the disassembly plate 16. A blocking plate 31 for the connecting plate 32 to pass through is fixedly installed at the opening of the buffer cavity. A spring 33 for pushing the connecting plate 32 toward the blocking plate 31 is placed in the buffer cavity.

[0034] In this embodiment, the blocking plate 31 can limit the connecting block 30 in the buffer cavity to prevent it from coming out, thus achieving a reliable connection between the disassembly plate 16 and the moving plate 14. When the moving plate 14 drives the buffer cylinder 21 to move towards the evaporator 11, the buffer cylinder 21 drives the disassembly plate 16 to move through the connecting block 30 and the connecting plate 32, so that the temperature probe 18 abuts against the outer wall of the evaporator 11. At this time, the spring 33 forms a buffer for the connecting block 30, reducing the contact impact force and preventing the temperature probe 18 from being damaged by hard collision, thereby improving the service life and operational stability of the temperature measuring component.

[0035] In this embodiment, the drive assembly includes two threaded rods 22 rotatably mounted on one side wall of the lifting block 25. One end of the threaded rod 22 is threaded through the moving plate 14, and the ends of the two threaded rods 22 away from the moving plate 14 are disposed through the lifting block 25. A first synchronous wheel 23 is fixedly sleeved on the through end of each threaded rod 22, and a first synchronous belt 24 is sleeved between the two first synchronous wheels 23. The side wall of the lifting block 25 away from the moving plate 14 is provided with a rotating component for driving one of the two threaded rods 22 to rotate.

[0036] In this embodiment, the threaded rod 22 is rotatably mounted on one side wall of the lifting block 25 via a bearing. When the rotating component drives one of the threaded rods 22 to rotate, the threaded rod 22 can drive the corresponding first synchronous wheel 23 to rotate. The rotation of the first synchronous wheel 23 can drive the first synchronous wheel 23 on the other threaded rod 22 to rotate via the first synchronous belt 24. That is, the first synchronous wheel 23 drives the other threaded rod 22 to rotate. When the two threaded rods 22 rotate synchronously, the threaded rod 22 and the moving plate 14 are threadedly engaged, so that the rotation can drive the moving plate 14 to move along the length direction of the threaded rod 22. The movement of the moving plate 14 can drive the disassembly plate 16 and the temperature probe 18 to move closer to or away from the evaporator 11 via the buffer cylinder 21.

[0037] In this embodiment, a first gear 29 is fixedly sleeved on the side wall of a threaded rod 22 away from the lifting block 25; The rotating component includes a bracket 26, which is fixedly installed on the side wall of the lifting block 25 away from the moving plate 14. A motor 20 is fixedly installed on the side wall of the bracket 26 away from the moving plate 14. The output shaft of the motor 20 passes through the bracket 26 and is fixedly sleeved on a second gear 34 that meshes with the first gear 29.

[0038] In this embodiment, when the output shaft of the motor 20 rotates, the output shaft of the motor 20 can drive the second gear 34 to rotate, the rotation of the second gear 34 can drive the meshing first gear 29, and the first gear 29 can drive one of its threaded rods 22 to rotate.

[0039] In this embodiment, a limiting plate is fixedly installed inside the mounting frame 13, and a limiting rod 28 that is opposite to and passes through the lifting block 25 is fixedly installed between the limiting plate and the lower side of the mounting frame 13. The lifting assembly is rotatably mounted on the upper end face of the base frame 12 with the lifting rod 17 threaded through the lifting block 25.

[0040] In this embodiment, the two ends of the lifting rod 17 are installed between the base frame 12 and the mounting frame 13 through bearings. The two limiting rods 28 limit the lifting block 25. When the lifting rod 17 rotates, the lifting rod 17 can drive the lifting block 25 to rise and fall along the height direction of the lifting rod 17, that is, the lifting block 25 rises and falls. The lower end of the lifting rod 17 passes through the base frame 12, and a second synchronous wheel 35 is fixedly sleeved on the through end of the lifting rod 17. A round rod 39 is rotatably installed on the upper surface of the base frame 12, and the lower end of the round rod 39 passes through the base frame 12. A third synchronous wheel 36 is fixedly sleeved on the through end of the round rod 39. A second synchronous belt 37 is sleeved between the second synchronous wheel 35 and the third synchronous wheel 36. When the operator drives the round rod 39 to rotate, the rotation of the round rod 39 can drive the third synchronous wheel 36 to rotate. The rotation of the third synchronous wheel 36 can drive the second synchronous wheel 35 to rotate through the second synchronous belt 37. The rotation of the second synchronous wheel 35 can drive the lifting rod 17 to rotate. The base frame 12 has multiple insertion holes along the circumference of the round rod 39 on its upper end face. The round rod 39 above the base frame 12 has a groove 42. The round rod 39 above the base frame 12 is slidably fitted with an insertion plate 38. A protrusion 43 is fixedly installed on the inner side wall of the insertion plate 38, which is inserted into the groove 42 at one end. Multiple insertion rods 44 are fixedly installed on the lower end face of the insertion plate 38. The round rod 39 above the base frame 12 is threaded with a nut 40. When the lifting rod 17 completes its rotation, it is necessary to position the lifting rod 17 after its rotation. At this time, by moving the insertion plate 38 on the round rod 39 down, the insertion rod 44 below the insertion plate 38 can be inserted into the base frame 12, thereby positioning the position of the insertion plate 38 after its rotation. The insertion plate 38, through the cooperation of the protrusion 43 and the groove 42, also positions the rotation of the round rod 39. When the insert plate 38 completes the positioning of the round rod 39, the nut 40 needs to be rotated. The nut 40 moves down along the round rod 39 and presses the insert plate 38 against the upper end face of the base frame 12, thereby preventing the insert rod 44 below the insert plate 38 from sliding out of the base frame 12 and thus affecting the positioning effect of the round rod 39. The upper end face of the insert plate 38 is fixedly installed with a pull rod 41. When the nut 40 is rotated, causing the nut 40 to move upward by a certain distance, the staff can lift the pull rod 41 and drive the insert plate 38 to rotate through the pull rod 41. The insert plate 38 then drives the round rod 39 to rotate, making the rotation of the round rod 39 more convenient.

[0041] In actual use, during operation, the drive assembly is powered by the motor 20, which drives one of the threaded rods 22 to rotate via the second gear 34 and the first gear 29. The first synchronous pulley 23 and the first synchronous belt 24 then synchronize the rotation of both threaded rods 22, thereby driving the moving plate 14 to move axially along the threaded rod 22. This movement, via the buffer cylinder 21, brings the disassembly plate 16 and the temperature probe 18 closer to the outer wall of the evaporator 11. When the temperature probe 18 contacts the outer wall of the evaporator 11, the spring 33 inside the buffer cylinder 21 provides elastic cushioning to the disassembly plate 16 through the connecting block 30 and the connecting plate 32, preventing... This design avoids damage caused by rigid contact between the temperature probe 18 and the evaporator 11. Simultaneously, the lifting assembly, via the round rod 39, second synchronous wheel 35, third synchronous wheel 36, and second synchronous belt 37, drives the lifting rod 17 to rotate. Under the guidance of the limit rod 28, it drives the lifting block 25 to move up and down, thereby causing the temperature probe 18 to dynamically detect at different positions on the outer wall of the evaporator 11. This solves the problems of single-point temperature measurement distortion and lag, accurately reflecting the overall cooling status of the evaporator 11. After the evaporator 11 stops working, the drive assembly moves the temperature probe 18 back away from the evaporator 11, and the lifting assembly lowers the temperature probe 18 to its lowest position. By rotating the screw 19 of the disassembly assembly, the limit of the disassembly block can be quickly released, enabling rapid disassembly of the temperature probe 18 for easy maintenance and replacement. The overall structure operates stably, providing comprehensive and reliable temperature measurement. It effectively optimizes the control of the refrigeration system, improves ice-making efficiency and ice layer uniformity, reduces equipment energy consumption, and extends the service life of the evaporator 11.

[0042] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
