Abstract

The application discloses a partition independent cold extraction heat exchange cooling structure of a filter press and belongs to the technical field of heat exchange cooling structures. The heat exchange mechanism is internally provided with two turbulence mechanisms in the upper and lower portions. The heat exchange mechanism comprises an assembling frame, a cooling assembly and two medium path adjusting assemblies arranged in the upper and lower portions of the cooling assembly respectively. Two adjacent medium path adjusting assemblies are in transmission connection with a transmission assembly. When the temperature of a certain heat exchange region increases, the nickel-titanium-based shape memory alloy can generate axial extension displacement due to heat, thereby prolonging the flow distance, heat exchange time and heat exchange range of the cooling medium, improving the heat exchange efficiency. Meanwhile, the tooth rod moves along with the nickel-titanium-based shape memory alloy, so that the first scraper frame moves along the heat exchange wall of the heat exchange shell, thereby reducing the adhesion and residence of the cooling medium near the heat exchange wall, disturbing the cooling medium and improving the heat exchange effect.

Description

Technical Field

[0001] This invention relates to the field of heat exchange and cooling structure technology, and in particular to a zoned independent cold extraction heat exchange and cooling structure for a filter press. Background Technology

[0002] During the operation of a filter press, the pressing, friction, and physicochemical reactions of the material continuously generate heat. Excessive local temperature rise can easily affect the quality of the filter media, the pressing stability, and the service life of the equipment. Therefore, it is necessary to rely on heat exchange and cooling structures to achieve constant temperature control in the working area. Existing cooling channels inside heat exchange plates mostly use straight channels, serpentine channels, or parallel channels of fixed length and cross-section. Their flow path remains basically unchanged during operation. When different heat exchange zones experience varying degrees of temperature rise due to factors such as material distribution, filter cake thickness, and feed conditions, the cooling medium still flows along the predetermined path, making it difficult to increase the effective heat exchange path and time for localized high-temperature areas. This easily leads to inconsistent cooling rates in different areas. Simultaneously, as the cooling medium flows continuously along the heat exchange wall, the medium near the wall absorbs heat and easily forms a relatively stable high-temperature liquid layer and thermal boundary layer, making it difficult for the cooler cooling medium in the center of the channel to participate in wall heat exchange in a timely manner. Especially when the flow path is long and has many turns, the temperature rise of the cooling medium along the path and the localized low-speed and stagnant flow phenomena are more pronounced. If continuous mechanical agitation is used to enhance heat transfer, the agitation mechanism will continue to operate even when the temperature has stabilized or when enhanced heat transfer is no longer necessary. This not only increases flow resistance and mechanical wear, but also creates ineffective disturbances.

[0003] To address the above problems, this invention proposes a partitioned independent cold extraction heat exchange and cooling structure for a filter press. Summary of the Invention

[0004] The purpose of this invention is to address the problem that the flow path of the cooling channel inside the existing heat exchange plate remains essentially unchanged during operation, making it difficult to increase the effective heat exchange path and heat exchange time for local high-temperature areas. Furthermore, the medium near the heat exchange wall tends to form a relatively stable high-temperature liquid layer and thermal boundary layer after absorbing heat, making it difficult for the cooler cooling medium in the center of the channel to participate in wall heat exchange in a timely manner. If continuous mechanical agitation is used to enhance heat exchange, the agitation mechanism continues to operate even when the temperature has stabilized or enhanced heat exchange is no longer necessary, which not only increases flow resistance and mechanical wear but also results in ineffective disturbance. Therefore, this invention proposes a zoned independent cold extraction heat exchange and cooling structure for a filter press.

[0007] Preferably, two adjacent medium path adjustment components are respectively disposed between two adjacent disturbance components, and two medium path adjustment components are staggered on the top and bottom. The nickel-titanium-based shape memory alloy of the medium path adjustment component and the inner wall of the heat exchange shell together form a serpentine flow channel. At the same time, the nickel-titanium-based shape memory alloy can expand and contract by changing the temperature of the cooling medium, thereby adjusting the flow length of the cooling medium in the serpentine flow channel.

[0008] Preferably, the medium path adjustment component includes a nickel-titanium-based shape memory alloy, a toothed rod, and an adjustment rod. One end of the toothed rod is fixedly connected to a first scraper frame, which overlaps with the inner wall of the heat exchange shell.

[0009] Preferably, an adjusting sleeve is fixedly connected to the rack, the adjusting sleeve is slidably connected to the adjusting rod, the adjusting rod is fixedly connected to the heat exchange shell, and multiple auxiliary sleeves are slidably connected to the adjusting rod. The multiple auxiliary sleeves are respectively fixedly connected to multiple bending points of the nickel-titanium-based shape memory alloy through multiple fasteners.

[0010] Preferably, the nickel-titanium-based shape memory alloy slides and fits against the front and rear inner walls of the heat exchange shell on both sides along the thickness direction of the heat exchange shell. Both sides of the nickel-titanium-based shape memory alloy are provided with connecting ends, one of which is fixedly connected to the inner wall of the heat exchange shell, and the other connecting end is fixedly connected to the adjusting sleeve through a connector.

[0011] Preferably, the transmission assembly includes a rotating shaft, which is rotatably mounted on the heat exchange shell via two first bearings. A gear is fixedly connected to the rotating shaft, and the upper and lower sides of the gear mesh with two adjacent racks, respectively.

[0012] Preferably, the disturbance component includes a drive shaft with a spiral groove. Both ends of the drive shaft are fixedly connected to turbulence blades, and both ends of the drive shaft are rotatably mounted on two fixed supports via second bearings. A second scraper frame is fixedly connected to each of the two fixed supports. The second scraper frame overlaps with the inner wall of the heat exchange shell, and the second scraper frame near the connector is fixedly connected to the connecting end.

[0013] Preferably, the drive assembly includes a support base and a fixed base. The support base is fixedly connected to the heat exchange shell. A second ring is fixedly connected to the support base. A plurality of second helical teeth are provided on one side of the second ring. The plurality of second helical teeth mesh with a plurality of first helical teeth respectively. The plurality of first helical teeth are fixedly connected to the first ring. The first ring is rotatably mounted on the fixed base through a third bearing. The drive shaft passes through the first ring and the second ring. A drive ball is fixedly connected in the first ring. The drive ball slides in conjunction with the helical groove.

[0014] Preferably, two guide sleeves are fixedly connected to the support base, and a guide rod is slidably connected to each of the two guide sleeves. One end of each guide rod is fixedly connected to the fixed base.

[0015] Compared with the prior art, the present invention provides a partitioned independent cold extraction heat exchange and cooling structure for a filter press, which has the following beneficial effects: 1. The filter press features a zoned independent cold extraction heat exchange and cooling structure. Through the serpentine flow channel formed by the inner cavity of the heat exchange shell and multiple media path adjustment components, when the temperature of a certain heat exchange area rises, the nickel-titanium-based shape memory alloy can be heated to generate axial extension displacement, extending the flow distance of the cooling medium, the heat exchange time, and the effective heat exchange range, thereby improving the heat exchange efficiency. At the same time, the toothed rod moves with the nickel-titanium-based shape memory alloy, causing the first scraper frame to move along the heat exchange wall of the heat exchange shell, reducing the adhesion and retention of the cooling medium near the heat exchange wall, and disturbing the cooling medium to further improve the heat exchange effect.

[0016] 2. The filter press features a zoned independent cold extraction heat exchange and cooling structure. By moving the disturbance component along with the axial extension displacement generated by the nickel-titanium-based shape memory alloy, the second scraper frame breaks the low-speed thermal boundary layer formed near the heat exchange wall of the heat exchange shell. At the same time, the drive ball and the arc surface of the spiral groove can cooperate to realize the rotation of the drive shaft and the disturbance blades. The rotation of the disturbance blades can dynamically disturb the cooling medium, increase the disturbance area, and enhance the lateral mixing between the cooling medium in different positions, thereby accelerating the heat exchange speed and ensuring the stable operation of the filter press.

[0017] 3. The filter press features a zoned independent cold extraction heat exchange and cooling structure. By adjusting the medium path, the cooling medium undergoes extended deformation due to heating, thus lengthening the flow path of the cooling medium in the high-temperature region. This allows for more thorough contact between the cooling medium and the heat exchange wall of the cooling component. Simultaneously, the linkage disturbance component disrupts the low-velocity thermal boundary layer formed near the heat exchange wall of the heat exchange shell. The disturbance component also rotates, continuously dynamically turbulent and mixing the fluid in the extended flow path, constantly renewing the high-temperature cooling medium near the heat exchange wall. This mitigates the adverse effects of the long flow path's temperature rise on subsequent heat exchange capacity, thereby improving the overall heat exchange efficiency and temperature uniformity of the heat exchange mechanism while simultaneously achieving zoned targeted cooling.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example 1: Refer to Figures 1-6 A partitioned independent cold extraction heat exchange and cooling structure for a filter press includes a heat exchange mechanism 100, which is disposed on the filter plate of the filter press and is arranged along the filtration working surface of the filter plate. At least one heat exchange wall of the heat exchange shell 1021 forms a thermally conductive fit with the plate wall of the filter plate near the filter chamber, so that the heat generated by the filter chamber and filter cake during the filtration process can be transferred to the heat exchange shell 1021 through the filter plate and absorbed by the cooling medium flowing through the heat exchange shell 1021. The water inlet 1023 and the water outlet 1022 are led out from the side of the filter plate and are respectively connected to the cooling medium circulation pipeline of the filter press. Two turbulence mechanisms 200 are provided at the top and bottom of the heat exchange mechanism 100. The heat exchange mechanism 100 includes an assembly frame 101, a cooling component 102, and two media path adjustment components 103 respectively disposed above and below the cooling component 102. Each media path adjustment component 103 includes a nickel-titanium-based shape memory alloy 1035, a toothed rod 1031, and an adjusting rod 1038. One end of the toothed rod 1031 is fixedly connected to a first scraper frame 1033, which can agitate and refresh the cooling medium near the heat exchange wall, thereby improving the heat exchange effect. The first scraper frame 1033 overlaps with the inner wall of the heat exchange shell 1021. An adjusting sleeve 1032 is fixedly connected to the toothed rod 1031, and the adjusting sleeve 1032 is slidably connected to the adjusting rod 1038. The adjusting rod 1038 guides the adjusting sleeve 1032, allowing it to... The adjusting sleeve 1032 moves smoothly along the adjusting rod 1038, thereby keeping the rack 1031 moving smoothly and allowing the first scraper frame 1033 to move smoothly and disturb the cooling medium. The adjusting rod 1038 is fixedly connected in the heat exchange shell 1021. Multiple auxiliary sleeves 1034 are slidably connected to the adjusting rod 1038. The multiple auxiliary sleeves 1034 are fixedly connected to multiple bending points of the nickel-titanium-based shape memory alloy 1035 by multiple fasteners 1037. By setting the nickel-titanium-based shape memory alloy 1035 into a continuously bent wavy shape, on the one hand, a large recoverable deformation can be formed in the limited internal space of the heat exchange shell 1021; on the other hand, by changing the degree of bending of each bending part, the shape of the material itself can be restored to the shape along the adjusting rod 1038. The displacement output in the 038 direction provides the operating stroke for the medium path adjustment component 103 and the disturbance component 201. Secondly, the nickel-titanium-based shape memory alloy 1035 uses a nickel-titanium-based shape memory material trained with two-way shape memory, enabling it to possess corresponding low-temperature and high-temperature shape memories at different temperature states. Specifically, when the heat exchange zone is at normal temperature, the nickel-titanium-based shape memory alloy 1035 maintains a relatively large wave-like low-temperature shape memory, with a relatively short effective length along the extension direction of the adjustment rod 1038. When the temperature of the corresponding heat exchange zone rises and reaches the operating temperature range of the nickel-titanium-based shape memory alloy 1035, a phase transition occurs. The shape memory alloy 1035 recovers its high-temperature shape memory shape, reducing the degree of bending at its multiple bends and generating an extension displacement along the axial direction of the adjusting rod 1038. Multiple auxiliary sleeves 1034 are connected to multiple bend positions of the nickel-titanium-based shape memory alloy 1035 and can slide along the adjusting rod 1038, thereby constraining the deformation direction of the nickel-titanium-based shape memory alloy 1035. This causes the deformation generated by the nickel-titanium-based shape memory alloy 1035 to be mainly converted into effective linear displacement along the direction of the adjusting rod 1038. When the temperature of the corresponding heat exchange region decreases, the nickel-titanium-based shape memory alloy 1035 gradually leaves the high-temperature operating state and, under the action of the two-way shape memory effect, recovers from the high-temperature shape memory to the low-temperature shape memory, causing the degree of bending at its multiple bends to increase again.This causes the effective length of the nickel-titanium-based shape memory alloy 1035 to shorten along the adjusting rod 1038. During this process, the connecting end 1036 drives the adjusting sleeve 1032 to move in the opposite direction along the adjusting rod 1038 via the connecting piece 1039, thereby driving the rack 1031, the first scraper frame 1033, and the disturbance component 201 linked with it to complete the reset. Thus, the nickel-titanium-based shape memory alloy 1035 can switch between the extended and retracted states by utilizing the temperature change of the heat exchange zone itself, without the need for a separate power actuator to drive its reciprocating motion. The nickel-titanium-based shape memory alloy 1035 slides against the front and rear inner walls of the heat exchange shell 1021 on both sides along the thickness direction. The side edges of the nickel-titanium-based shape memory alloy 1035 slide against the inner wall of the heat exchange shell 1021, ensuring that the cooling medium flows above. Both sides of the nickel-titanium-based shape memory alloy 1035 are provided with connecting ends 1036. One connecting end 1036 is fixedly connected to the inner wall of the heat exchange shell 1021, and the other connecting end 1036 is fixedly connected to the adjusting sleeve 1032 through the connector 1039. Two adjacent medium path adjustment components 103 are connected to the transmission component 104. The transmission component 104 includes a rotating shaft 1042, which is rotatably mounted on the heat exchange shell 1021 via two first bearings 1043. A gear 1041 is fixedly connected to the rotating shaft 1042, and the upper and lower sides of the gear 1041 mesh with two adjacent racks 1031, respectively. The cooling component 102 is disposed in the assembly frame 101. The cooling component 102 includes a heat exchange shell 1021, which is fixedly mounted in the assembly frame 101. The device is provided with an inlet end 1023 and an outlet end 1022 at both ends. Two adjacent medium path adjustment components 103 are respectively arranged between two adjacent disturbance components 201. The upper and lower two medium path adjustment components 103 are arranged alternately. The nickel-titanium-based shape memory alloy 1035 of the medium path adjustment component 103 and the inner wall of the heat exchange shell 1021 together form a serpentine flow channel. At the same time, the nickel-titanium-based shape memory alloy 1035 can expand and contract displacement by changing the temperature of the cooling medium, thereby adjusting the flow length of the cooling medium in the serpentine flow channel. The turbulence mechanism 200 includes a turbulence component 201, which is rotatably engaged with the drive component 202.

[0022] In this embodiment: through the serpentine flow channel formed by the inner cavity of the heat exchange shell 1021 and multiple medium path adjustment components 103, when the temperature of a certain heat exchange area rises, the nickel-titanium-based shape memory alloy 1035 can be heated to generate shape recovery displacement, causing the cooling medium in that area to switch from a shorter flow path to a longer flow path, thereby increasing the flow distance, heat exchange time, and effective heat exchange range of the cooling medium in the high-temperature area, so that more cooling capacity is concentrated on the area with a significant temperature rise. At the same time, the toothed rod 1031 moves with the nickel-titanium-based shape memory alloy 1035, causing the first scraper frame 1033 to move along the heat exchange wall of the heat exchange shell 1021, disturbing the cooling medium near the heat exchange wall of the heat exchange shell 1021, so that the cooling medium that has absorbed heat and heated up and stayed near the heat exchange wall can be removed from the wall in time. At the same time, it causes the relatively low-temperature cooling medium in the serpentine flow channel to move closer to the heat exchange wall, thereby reducing the adverse effects of the stable liquid film and thermal boundary layer on the heat transfer process, improving the local heat exchange efficiency in the high-temperature area, and improving the cooling uniformity between the heat exchange areas.

[0023] Example 2: Refer to Figures 7-9 A partitioned independent cold extraction heat exchange and cooling structure for a filter press includes a disturbance component 201. The disturbance component 201 includes a drive shaft 2011 with a spiral groove 2012. Both ends of the drive shaft 2011 are fixedly connected to turbulence blades 2013. The turbulence blades 2013 can stir and mix the cooling medium, enabling the cooling medium to quickly perform heat exchange. Both ends of the drive shaft 2011 are rotatably mounted on two fixed supports 2014 via second bearings 2016. A second scraper frame 2015 is fixedly connected to each of the two fixed supports 2014. The second scraper frame 2015 overlaps with the inner wall of the heat exchange shell 1021. The second scraper frame 2015 near the connector 1039 is fixedly connected to the connecting end 1036. The drive assembly 202 includes a support base 2025 and a fixed base 2021. Two guide sleeves 2029 are fixedly connected to the support base 2025. Guide rods 2028 are slidably connected to each of the two guide sleeves 2029. The guide rods 2028 support the fixed base 2021 and can slide within the guide sleeves 2029, allowing the fixed base 2021 to move smoothly. One end of each guide rod 2028 is fixedly connected to the fixed base 2021. The support base 2025... 5. Fixedly connected in the heat exchange shell 1021, a second ring 2026 is fixedly connected to the support base 2025. A plurality of second helical teeth 2027 are provided on one side of the second ring 2026, and the plurality of second helical teeth 2027 respectively mesh with a plurality of first helical teeth 2024. The plurality of first helical teeth 2024 are fixedly connected to the first ring 2022. The first ring 2022 is rotatably mounted on the fixed base 2021 via a third bearing 2023. The drive shaft 20... 11 extends from the first ring sleeve 2022 and the second ring sleeve 2026. A driving ball 20210 is fixedly connected in the first ring sleeve 2022. The driving ball 20210 slides with the spiral groove 2012 and is locked by the first helical tooth 2024 and the second helical tooth 2027. When the disturbance component 201 moves with the shape recovery displacement of the nickel-titanium-based shape memory alloy 1035, the driving ball 20210 directly engages with the spiral groove 2012 to realize the rotation of the transmission shaft 2011. When the nickel-titanium-based shape memory alloy 1035 retracts and resets, the spiral groove 2012 and the driving ball 20210 generate a certain limiting force, so that the first ring sleeve 2022 is subjected to force that can disengage the first helical tooth 2024 from the second helical tooth 2027. At the same time, the first ring sleeve 2022 can rotate, thereby avoiding the rotation of the transmission shaft 2011 and the disturbance blade 2013, and avoiding unnecessary rotational movement of the disturbance blade 2013.

[0024] In this embodiment: the disturbance component 201 moves by following the shape recovery displacement of the nickel-titanium-based shape memory alloy 1035, causing the second scraper frame 2015 to break the low-speed thermal boundary layer formed near the heat exchange wall of the heat exchange shell 1021. At the same time, the drive ball 20210 and the spiral groove 2012 cooperate to realize the rotational movement of the drive shaft 2011 and the turbulence blade 2013, so that the originally relatively stable flow of cooling medium in the heat exchange shell 1021 is dynamically disturbed, enhancing the lateral mixing between cooling media at different positions, and carrying the cooling medium that is close to the heat exchange wall and has absorbed heat and increased in temperature away from the middle of the serpentine flow channel. At the same time, the cooling medium with a lower temperature in the middle of the serpentine flow channel is continuously transported to the vicinity of the heat exchange wall, accelerating the exchange rate of hot and cold cooling media, thereby accelerating the heat exchange rate and ensuring the stable operation of the filter press.

[0025] Example 3: Reference Figures 1-5A filter press with independent cold extraction heat exchange and cooling structure includes a heat exchange mechanism 100. The heat exchange mechanism 100 includes an assembly frame 101, a cooling component 102, and two media path adjustment components 103 respectively disposed in the upper and lower parts of the cooling component 102. Two adjacent media path adjustment components 103 are connected to a transmission component 104. The cooling component 102 is disposed in the assembly frame 101. The turbulence mechanism 200 includes a turbulence component 201, which is rotatably engaged with the drive component 202.

[0026] In this embodiment: the medium path adjustment component 103 is heated and undergoes an extension deformation, thereby extending the flow path of the cooling medium in the high-temperature region, allowing the cooling medium to have a more sufficient contact process with the heat exchange wall of the cooling component 102. At the same time, it can be linked with the disturbance component 201 to break the low-velocity thermal boundary layer formed near the heat exchange wall of the heat exchange shell 1021. Meanwhile, the disturbance component 201 rotates to continuously perform dynamic turbulence and fluid mixing on the extended flow path, so that the high-temperature cooling medium near the heat exchange wall is constantly renewed, thereby weakening the adverse effects of the long flow path heating on the subsequent heat exchange capacity. Thus, while taking into account the targeted cooling of different zones, the overall heat exchange efficiency and temperature uniformity of the heat exchange mechanism 100 are further improved.

[0027] Working principle: During heat exchange, the cooling medium can enter the heat exchange shell 1021 through the inlet 1023 and flow along the surface of the staggered nickel-titanium-based shape memory alloy 1035, thereby exchanging heat and cooling during the filter press process. The cooled medium after heat exchange is finally discharged from the outlet 1022 and returned to the cooling equipment for cooling and recycling. When the temperature in a localized heat exchange area of ​​the heat exchange shell 1021 continues to rise, the nickel-titanium-based shape memory alloy 1035 transforms from a low-temperature shape memory to a high-temperature shape memory, resulting in axial extension displacement and increasing the flow distance of the cooling medium. Simultaneously, the nickel-titanium-based shape memory alloy 1035, through the connecting end 1036, drives the connecting piece 1039 and the adjusting sleeve 1032 to move, causing the rack 1031 to move. The two racks 1031, driven by the gear 1041, can move relative to each other, causing the first scraper frame 1033 to move and disrupt the low-velocity thermal boundary layer formed near the heat exchange wall of the heat exchange shell 1021. At the same time, the moving… The connecting end 1036 also drives the second scraper frame 2015 to move. The second scraper frame 2015 simultaneously destroys the low-speed thermal boundary layer formed near the heat exchange wall of the heat exchange shell 1021. At the same time, the second scraper frame 2015 drives the drive shaft 2011 to move through the fixed bracket 2014. Since the first helical tooth 2024 and the second helical tooth 2027 are engaged and locked, the position of the first ring 2022 is locked. The driving ball 20210 can cooperate with the arc surface of the spiral groove 2012 to drive the drive shaft 2011 to rotate. The rotation of the turbulence blade 2013 can make the cooling medium mix laterally and improve the heat exchange effect of the cooling medium. When the temperature in the local high-temperature area returns to normal, the nickel-titanium-based shape memory alloy 1035 automatically retracts, resetting the first scraper frame 1033. Simultaneously, the disturbance component 201 also resets. Through the engagement of the drive ball 20210 and the spiral groove 2012, the first ring sleeve 2022 is subjected to a force away from the second ring sleeve 2026, causing the first helical tooth 2024 to disengage from the second helical tooth 2027. At the same time, the first ring sleeve 2022 can rotate, allowing the drive shaft 2011 to maintain translational reset and preventing the rotation of the disturbance blade 2013. When the drive shaft 2011 moves again along the extension direction of the nickel-titanium-based shape memory alloy 1035, the first helical tooth 2024 and the second helical tooth 2027 re-engage and lock the first ring sleeve 2022, thereby enabling the engagement of the drive ball 20210 and the spiral groove 2012 to achieve the rotation of the disturbance component 201 again.
