Description

Technical Field

[0001] The present invention relates to the technical field of heat exchangers, and particularly to an integral graphite cage-type graphite heat exchanger. Background Art

[0002] A graphite heat exchanger generally refers to a heat exchanger whose heat transfer components are made of graphite. Relying on the acid corrosion resistance and good heat conduction performance of graphite, the graphite is made into a flow guiding device. At this time, the high-temperature medium continuously transfers heat to the graphite heat exchanger, and the low-temperature medium continuously obtains heat from the heat exchanger, thereby realizing heat exchange.

[0003] The patent with the patent publication number CN211261935U discloses an integral graphite cage-type graphite heat exchanger, which includes an upper head and a lower head; the heat exchanger further includes a graphite cylinder, the upper head is adhesively arranged at the upper end of the graphite cylinder to form an upper annular cavity, and the lower annular cavity is divided into several upper chambers, the lower head is adhesively arranged at the lower end of the graphite cylinder to form a lower annular cavity, and the lower annular cavity is divided into several lower chambers; a plurality of transverse through holes and a plurality of longitudinal through holes are arranged on the graphite cylinder, the transverse through holes horizontally penetrate through the side wall of the graphite cylinder, the direction of the transverse through holes deviates from the center of the graphite cylinder by an angle, all the transverse through holes are divided into several columns and arranged in a circle, the longitudinal through holes vertically penetrate through the upper and lower end faces of the graphite cylinder to communicate the upper chambers and the lower chambers, all the longitudinal through holes are divided into several groups, and each group of longitudinal through holes is located between two adjacent columns of transverse through holes and is evenly distributed; all the upper chambers and all the lower chambers are connected in series into a loop through the longitudinal through holes. The use of an integral graphite cylinder design is convenient for workers to operate; the heat exchange efficiency is high.

[0004] However, this device still has deficiencies: the device is convenient to operate and has a high heat exchange efficiency. However, during the long-term use of the heat exchanger, water droplets are likely to be generated inside the heat exchanger due to the intersection of hot and cold gases. The water droplets adhere to the inner wall of the heat exchanger and are dried by heat, thereby accelerating the oxidation rate of the inner wall of the heat exchanger, increasing the probability of damage to the heat exchanger, and to a certain extent, easily reducing the durability of the heat exchanger. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an integral graphite cage-type graphite heat exchanger, which solves the problems put forward in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: An integral graphite birdcage type graphite heat exchanger, including a support assembly, on the top of the support assembly is provided a heat exchange assembly, on the right side of the heat exchange assembly is provided a sealing end, and on the outer wall of the left end of the heat exchange assembly are symmetrically and fixedly installed a number of circulation pipes, at the left end of the heat exchange assembly is provided a cold water pipe, at the bottom of the right end of the heat exchange assembly is provided a heat flow pipe, inside the heat exchange assembly are provided two tube sheets, the two tube sheets are symmetrically distributed with the center of the heat exchange assembly as the center, inside the tube sheets are provided graphite tube bundles, and on the outer wall of the graphite tube bundles are provided baffle plates;

[0007] Inside the left end of the heat exchange assembly is provided an anti-oxidation device, inside the anti-oxidation device is provided an anti-retardation device, and inside the anti-retardation device is provided an anti-interference device;

[0008] The anti-oxidation device includes an electric slide rail, the electric slide rail is arranged at the left end inside the heat exchange assembly, on the left side of the leftmost tube sheet is fixedly connected to the right side of the electric slide rail, inside the electric slide rail is slidably installed a transmission rod, the transmission rod is located on the left side of the electric slide rail, on the side of the transmission rod close to the cold water pipe is fixedly installed a filter plate, and the connection between the filter plate and the transmission rod is non-concentric, the outer wall of the filter plate is in contact with the inner wall of the heat exchange assembly, at the edge of the side of the filter plate close to the cold water pipe are equidistantly and rotatably installed a number of transmission rollers, on the side of the transmission roller close to the cold water pipe is fixedly installed a cross bar, on the outer wall of the cross bar is provided a reciprocating spiral groove, on the outer wall of the reciprocating spiral groove of the cross bar is movably installed a push ring, on the side of the push ring close to the cold water pipe is fixedly installed on a sieve plate, at the center of the side of the filter plate close to the cold water pipe is fixedly installed a limiting rod. By injecting cold flow through the cold water pipe and hot flow through the heat flow pipe, after the cold flow and the hot flow enter the inside of the heat exchange assembly, heat exchange treatment is carried out through the graphite tube bundles. At the same time, the tube sheets limit and seal the graphite tube bundles, and at the same time, the baffle plates improve the heat transfer coefficient of the graphite tube bundles. Relying on the good conduction performance of graphite and the conduction of the baffle plates, the heat exchange efficiency of the heat exchange assembly is ensured. Before the cold flow enters the inside of the heat exchange assembly, start the electric slide rail, the electric slide rail drives the transmission rod to revolve inside itself, the transmission rod drives the filter plate to revolve along the inner wall of the heat exchange assembly, and when the filter plate revolves, it rotates and blocks the cold flow entering the inside of the heat exchange assembly; when the filter plate revolves, it drives the transmission rollers to revolve, when the transmission rollers revolve, they contact the inner wall of the heat exchange assembly to generate frictional force, the transmission rollers start to rotate by themselves due to the frictional force and drive the cross bar to rotate, when the cross bar rotates, through the restriction of the built-in block of the push ring by the reciprocating spiral groove on its outer wall, the push ring can slide horizontally along the outer wall of the cross bar towards the direction close to the cold water pipe and reset, and the push ring pushes the sieve plate to slide synchronously along the outer wall of the limiting rod.

[0009] According to the above technical solution, the outer walls of a number of the transmission rollers are all in contact with the inner wall of the heat exchange assembly, and inside the transmission rollers are provided transmission grooves, the sieve plate is located on the left side of the filter plate, and the outer wall of the limiting rod is slidably installed inside the sieve plate.

[0010] According to the above technical scheme, the anti-delay device includes a transmission belt, a rotating column, a plurality of round rods and a friction cotton roller. The transmission belt is installed in the transmission groove of the transmission roller for internal transmission at one end close to the inner wall of the heat exchange component. The rotating column is rotatably installed on the left side of the filter plate away from the screen plate. Several round rods are fixedly installed on the outer wall of the rotating column. The inner wall of the friction cotton roller is rotatably installed on the outer wall of the round rod. When the transmission roller rotates, the rotating column is driven to rotate along the left outer wall of the filter plate through the transmission belt. When the rotating column rotates, it drives the round rod to rotate. The round rod drives the friction cotton roller to revolve along the left outer wall of the filter plate. When solidified impurity particles are attached to the outer wall of the filter plate, the friction cotton roller increases the friction between itself and the filter plate through the obstruction of the impurity particles. At this time, the friction cotton roller is deformed by friction resistance and rotates along the outer wall of the round rod.

[0011] According to the above technical solution, the outer wall of the rotating column is transmission-connected to one end of the transmission belt away from the inner wall of the heat exchange component, a plurality of the round rods are evenly distributed on the outer wall of the rotating column, and the outer wall of the friction cotton roller contacts the left side of the filter plate.

[0012] The U-shaped magnetic plate is located on the right side of the filter plate, and a circular groove is provided inside the U-shaped magnetic plate. The anti-skid wheel is rotatably installed on the inner wall of the U-shaped magnetic plate away from the side of the through-rod, and the outer wall of the anti-skid wheel contacts the right side of the filter plate. When the rotating column rotates, the through-rod is driven to rotate, and the through-rod drives the U-shaped magnetic plate to revolve. When the U-shaped magnetic plate revolves, it drives the anti-skid wheel to move synchronously along the outer wall of the right side of the filter plate. The anti-skid wheel starts to rotate due to the friction between the filter plate and the filter plate, thereby the anti-skid wheel converts the sliding friction between the U-shaped magnetic plate and the filter plate into rolling friction.

[0013] When the anti-skid wheel rotates, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the built-in clamping block of the U-shaped plate through the reciprocating spiral groove on its outer wall. At this time, the U-shaped plate is limited by the U-shaped magnetic plate, so that it can slide along the outer wall of the reciprocating screw. When the U-shaped plate slides vertically in the direction away from the penetrating rod, the U-shaped plate will resist the inner wall of the gathering plate to generate a resistance force. At this time, the gathering plate flips in the direction away from the penetrating rod with its own hinge axis as the axis, and then the gathering plate is reset by the torsion spring.

[0014] According to the above technical solution, the inner wall of the U-shaped plate is slidably installed on the side of the U-shaped magnetic plate close to the filter plate. A torsion spring is arranged between the converging plate and the U-shaped magnetic plate, and the converging plate has magnetism. The converging plate is located on the movement track of the U-shaped plate.

[0015] According to the above technical solution, the anti-interference device further includes a friction plate, a hook-shaped plate, a support rod, and a turning plate. The side of the friction plate close to the U-shaped magnetic plate is slidably installed on the outer wall of the converging plate. The hook-shaped plate is hinged between the outer wall of the friction plate and the outer wall of the U-shaped magnetic plate. Both ends of the support rod are fixedly installed on the inner wall of the U-shaped magnetic plate return groove. The inside of the turning plate is rotationally installed on the outer wall of the support rod through a torsion spring. The turning plate is located on the movement track of the U-shaped plate close to the through rod side, and a detection component is built in the turning plate. When the converging plate turns, it drives the friction plate to move synchronously. The friction plate is limited by the hook-shaped plate, which causes the hinge shaft of the friction plate to start rotating. The hook-shaped plate pushes the friction plate to slide along the outer wall of the converging plate. When the friction plate slides to the maximum sliding range, it will contact the hook-shaped plate and cause deformation. At this time, the hook-shaped plate limits the friction plate, and the friction plate limits the turning angle of the converging plate. When the U-shaped plate slides towards the through rod, it contacts and presses the turning plate. The turning plate is limited by the support rod to enable itself to turn upward along the outer wall of the support rod. During the upward turning process of the turning plate, it contacts the cold flow, and the turning plate detects the metal content in the cold flow through the built-in detection component.

[0016] The present invention provides an integral graphite birdcage type graphite heat exchanger. It has the following beneficial effects:

[0017] (1) Through the setting of the anti-oxidation device in the present invention, through the cooperation of the electric slide rail, the transmission rod, the filter plate, the transmission roller, the cross bar, the push ring, the sieve plate, and the limiting rod, the cold flow is preliminarily preheated by the revolution of the filter plate, preventing water droplets from adhering to the inner wall of the heat exchange component due to excessive temperature difference when the cold flow directly exchanges heat with the hot flow, and avoiding the acceleration of the oxidation rate of the inner wall of the heat exchange component during the process of drying the water droplets by heat, thereby reducing the durability of the heat exchange component; at the same time, the impurities in the cold flow are further removed by the interlayer between the sieve plate and the filter plate, and the reciprocating sliding of the sieve plate enables the impurities to be more evenly distributed to prevent the filter holes from being blocked, effectively avoiding the adhesion and solidification of impurities inside the heat exchange component, resulting in a reduction in the smoothness of the inner wall, and avoiding the aggravation of the oxidation phenomenon due to the unevenness of the inner wall of the heat exchange component.

[0018] (2) Through the setting of the anti-delay device, the present invention cooperates with a transmission roller, a transmission belt, a rotating column, a round rod, a friction cotton roller, a through rod, a U-shaped magnetic plate, and an anti-slip wheel. Relying on the revolution and rotation of the friction cotton roller, during the process of the round rod disturbing the cold flow for uniform heat exchange, the friction cotton roller erases the solidified impurities on the surface of the filter plate by deforming and rotating, avoiding excessive attachment of dirt and impurities on the surface of the filter plate during long-term use, preventing the delay of the heat exchange process between the cold flow and the hot flow and reducing the heat exchange efficiency; and effectively reducing the friction loss of the U-shaped magnetic plate, while relying on the U-shaped magnetic plate to stir the cold flow a second time, avoiding the cold flow gathering and pouring in, resulting in difficulty in timely heat exchange in the middle part of the cold flow, thereby increasing energy consumption.

[0019] (3) Through the setting of the anti-interference device, the present invention cooperates with an anti-slip wheel, a reciprocating lead screw, a U-shaped plate, a gathering plate, a friction plate, a hook-shaped plate, a support rod, and a flipping plate. Relying on the gathering plate to flap the cold flow during the flowing process, promoting the cold flow to surge towards the direction close to the U-shaped magnetic plate, and using the U-shaped magnetic plate and its own magnetism to adsorb and remove the metal components contained in the cold flow, preventing the metal components in the cold flow from directly flushing and covering the outer wall of the graphite tube bundle and interfering with the heat conduction characteristics of the graphite tube bundle; and effectively limiting the flipping angle and amplitude of the gathering plate, avoiding the phenomenon of the gathering plate being reversely folded and damaged under the influence of the fluid during the flipping process, while relying on the flipping plate and the detection component to monitor the metal content in the cold flow in real time, and transmitting information through the intelligent information module, facilitating the staff to judge whether the overall equipment needs to be cleaned and maintained.

Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] Please refer to Figures 1-8 , an embodiment of the present invention is: an integral graphite birdcage type graphite heat exchanger, including a support component 1. A heat exchange component 2 is arranged on the top of the support component 1. A sealing end is arranged on the right side of the heat exchange component 2. A plurality of circulation pipes are symmetrically and fixedly installed on the outer wall of the left end of the heat exchange component 2. A cold water pipe 21 is arranged at the left end of the heat exchange component 2. A heat flow pipe 22 is arranged at the bottom of the right end of the heat exchange component 2. Two tube sheets 3 are arranged inside the heat exchange component 2, and the two tube sheets 3 are symmetrically distributed with the center of the heat exchange component 2 as the center. A graphite tube bundle 31 is arranged inside the tube sheet 3, and a baffle plate 32 is arranged on the outer wall of the graphite tube bundle 31;

[0031] An anti-oxidation device 4 is arranged at the left end inside the heat exchange component 2. An anti-delay device 5 is arranged inside the anti-oxidation device 4. An anti-interference device 6 is arranged inside the anti-delay device 5;

[0032] The anti-oxidation device 4 includes an electric slide rail 41. The electric slide rail 41 is arranged at the left end inside the heat exchange component 2. The left side of the tube sheet 3 at the left end is fixedly connected to the right side of the electric slide rail 41. A transmission rod 42 is slidably installed inside the electric slide rail 41. The transmission rod 42 is located on the left side of the electric slide rail 41. A filter plate 43 is fixedly installed on the side of the transmission rod 42 close to the cold water pipe 21, and the connection between the filter plate 43 and the transmission rod 42 is non-concentric. The outer wall of the filter plate 43 contacts the inner wall of the heat exchange component 2. A number of transmission rollers 44 are rotatably installed at equal intervals on the edge of the filter plate 43 close to the cold water pipe 21. A cross bar 45 is fixedly installed on the side of the transmission roller 44 close to the cold water pipe 21. A reciprocating spiral groove is formed on the outer wall of the cross bar 45. A push ring 46 is movably installed on the outer wall of the reciprocating spiral groove of the cross bar 45. A sieve plate 47 is fixedly installed on the side of the push ring 46 close to the cold water pipe 21. A limiting rod 48 is fixedly installed at the center of the side of the filter plate 43 close to the cold water pipe 21. Through the above cooperation, the cold flow is preliminarily preheated by relying on the revolution of the filter plate 43, preventing water droplets from adhering to the inner wall of the heat exchange component 2 due to excessive temperature difference when the cold flow directly exchanges heat with the hot flow, and avoiding the acceleration of the oxidation rate of the inner wall of the heat exchange component 2 during the process of drying the water droplets by heat, thereby reducing the durability of the heat exchange component 2; through the above cooperation, the impurity particles in the cold flow are further removed by relying on the interlayer between the sieve plate 47 and the filter plate 43, and the reciprocating sliding of the sieve plate 47 promotes the relatively uniform distribution of the impurities to prevent the filter holes from being blocked, effectively avoiding the adhesion and solidification of the impurities inside the heat exchange component 2, resulting in a reduction in the smoothness of the inner wall, and avoiding the aggravation of the oxidation phenomenon due to the unevenness of the inner wall of the heat exchange component 2.

[0033] The outer walls of a number of transmission rollers 44 all contact the inner wall of the heat exchange component 2, and a transmission groove is formed inside the transmission roller 44. The sieve plate 47 is located on the left side of the filter plate 43, and the outer wall of the limiting rod 48 is slidably installed inside the sieve plate 47.

[0034] During use, cold fluid is injected through the cold water pipe 21, and hot fluid is injected through the hot fluid pipe 22. After the cold fluid and the hot fluid enter the heat exchange component 2, heat exchange treatment is carried out through the graphite tube bundle 31. At the same time, the tube sheet 3 limits and seals the graphite tube bundle 31. At the same time, the baffle plate 32 improves the heat transfer coefficient of the graphite tube bundle 31. Relying on the good conduction performance of graphite and the conduction of the baffle plate 32, the heat exchange component 2 has good heat exchange efficiency; before the cold fluid enters the heat exchange component 2, the electric slide rail 41 is started. The electric slide rail 41 drives the transmission rod 42 to revolve inside itself. The transmission rod 42 drives the filter plate 43 to revolve along the inner wall of the heat exchange component 2. When the filter plate 43 revolves, it rotates and blocks the cold fluid entering the heat exchange component 2. Through the above cooperation, the cold fluid is preliminarily preheated by relying on the revolution of the filter plate 43, preventing water droplets from adhering to the inner wall of the heat exchange component 2 due to excessive temperature difference when the cold fluid and the hot fluid directly exchange heat, and avoiding accelerating the oxidation rate of the inner wall of the heat exchange component 2 during the process of drying the water droplets by heat, thereby reducing the durability of the heat exchange component 2; when the filter plate 43 revolves, it drives the transmission roller 44 to revolve. When the transmission roller 44 revolves, it generates friction force when contacting the inner wall of the heat exchange component 2. The transmission roller 44 starts to rotate by itself due to the friction force and drives the cross bar 45 to rotate. When the cross bar 45 rotates, through the restriction of the built-in block of the push ring 46 by the reciprocating spiral groove on its outer wall, the push ring 46 can slide horizontally along the outer wall of the cross bar 45 towards the direction close to the cold water pipe 21 and reset. The push ring 46 pushes the sieve plate 47 to slide synchronously along the outer wall of the limiting rod 48. Through the above cooperation, the impurity particles in the cold fluid are further removed by relying on the interlayer between the sieve plate 47 and the filter plate 43, and the reciprocating sliding of the sieve plate 47 enables the impurities to be more evenly distributed to prevent the filter holes from being blocked, effectively avoiding the adhesion and solidification of impurities inside the heat exchange component 2, which reduces the smoothness of the inner wall, and avoiding the aggravation of the oxidation phenomenon due to the unevenness of the inner wall of the heat exchange component 2.

[0035] Please refer to Figures 1-8 , on the basis of the above embodiments, in another embodiment of the present invention, an anti-delay device 5 is further included;

[0036] The anti-delay device 5 includes a transmission belt 51, a rotating column 52, a plurality of round rods 53 and a friction cotton roller 54. One end of the transmission belt 51 close to the inner wall of the heat exchange component 2 is internally installed in the transmission groove of the transmission roller 44. The rotating column 52 is rotatably installed on the left side of the filter plate 43 away from the sieve plate 47. A plurality of round rods 53 are fixedly installed on the outer wall of the rotating column 52. The inner wall of the friction cotton roller 54 is rotatably installed on the outer wall of the round rod 53. Through the above cooperation, relying on the revolution and rotation of the friction cotton roller 54, during the process of disturbing the cold fluid by the round rod 53 for uniform heat exchange, the friction cotton roller 54 erases the impurities solidified on the surface of the filter plate 43 by relying on deformation and rotation, avoiding excessive adhesion of dirt and impurities on the surface of the filter plate 43 during long-term use, and preventing the delay of the heat exchange process between the cold fluid and the hot fluid, resulting in a reduction in heat exchange efficiency.

[0037] The outer wall of the rotating column 52 is drivingly connected to one end of the conveyor belt 51 away from the inner wall of the heat exchange assembly 2. A number of round rods 53 are evenly distributed on the outer wall of the rotating column 52. The outer wall of the friction cotton roller 54 is in contact with the left side of the filter plate 43.

[0038] The anti-delay device 5 further includes a through rod 55, a U-shaped magnetic plate 56 and an anti-slip wheel 57. The left end of the through rod 55 penetrates and is fixedly installed on the right side of the rotating column 52. The U-shaped magnetic plate 56 is fixedly installed on the outer wall of the through rod 55. The U-shaped magnetic plate 56 is located on the right side of the filter plate 43, and a return groove is formed inside the U-shaped magnetic plate 56. The anti-slip wheel 57 is rotatably installed on the inner wall of the U-shaped magnetic plate 56 on the side away from the through rod 55. The outer wall of the anti-slip wheel 57 is in contact with the right side of the filter plate 43. Through the above cooperation, the friction loss of the U-shaped magnetic plate 56 is effectively reduced. At the same time, the U-shaped magnetic plate 56 is relied on to agitate the cold flow for the second time to avoid the cold flow gathering and pouring in, resulting in the difficulty of timely heat exchange in the central part of the cold flow, thereby increasing the energy loss.

[0039] During use, when the driving roller 44 rotates, it drives the rotating column 52 to rotate along the left outer wall of the filter plate 43 through the conveyor belt 51. When the rotating column 52 rotates, it drives the round rod 53 to rotate. The round rod 53 drives the friction cotton roller 54 to revolve along the left outer wall of the filter plate 43. When there are solidified impurity particles attached to the outer wall of the filter plate 43, the friction cotton roller 54 increases the friction between itself and the filter plate 43 through the obstruction of the impurity particles. At this time, the friction cotton roller 54 deforms due to the frictional resistance and rotates along the outer wall of the round rod 53. Through the above cooperation, relying on the revolution and rotation of the friction cotton roller 54, during the process of the round rod 53 disturbing the cold flow for uniform heat exchange, the friction cotton roller 54 relies on deformation and rotation to wipe off the solidified impurities on the surface of the filter plate 43, avoiding excessive attachment of dirt and impurities on the surface of the filter plate 43 during long-term use, and preventing the delay of the heat exchange process between the cold flow and the hot flow, resulting in a reduction in heat exchange efficiency; when the rotating column 52 rotates, it drives the through rod 55 to rotate. The through rod 55 drives the U-shaped magnetic plate 56 to revolve. When the U-shaped magnetic plate 56 revolves, it drives the anti-slip wheel 57 to move synchronously along the right outer wall of the filter plate 43. The anti-slip wheel 57 starts to rotate due to the friction with the filter plate 43. Thus, the anti-slip wheel 57 converts the sliding friction between the U-shaped magnetic plate 56 and the filter plate 43 into rolling friction. Through the above cooperation, the friction loss of the U-shaped magnetic plate 56 is effectively reduced. At the same time, the U-shaped magnetic plate 56 is relied on to agitate the cold flow for the second time to avoid the cold flow gathering and pouring in, resulting in the difficulty of timely heat exchange in the central part of the cold flow, thereby increasing the energy loss.

[0040] Please refer to Figures 1-8 , on the basis of the above embodiments, another embodiment of the present invention further includes an anti-interference device 6;

[0041] The anti-interference device 6 includes a reciprocating lead screw 61, a U-shaped plate 62 and a converging plate 63. Both ends of the reciprocating lead screw 61 are fixedly installed at the center of the inner wall of the anti-slip wheel 57. The inner part of one end of the U-shaped plate 62 close to the filter plate 43 is movably installed on the outer wall of the reciprocating lead screw 61. One end of the converging plate 63 far from the penetrating rod 55 is hinged to the outer wall of the U-shaped magnetic plate 56. Through the above cooperation, the converging plate 63 flaps the cold flow during the flowing process, prompting the cold flow to surge towards the direction close to the U-shaped magnetic plate 56, and adsorbing and removing the metal components contained in the cold flow by means of the magnetism of the U-shaped magnetic plate 56 and itself, preventing the metal components in the cold flow from directly flushing and covering the outer wall of the graphite tube bundle 31 and interfering with the heat conduction characteristics of the graphite tube bundle 31.

[0042] The inner wall of the U-shaped plate 62 is slidably installed on the side of the U-shaped magnetic plate 56 close to the filter plate 43. A torsion spring is provided between the converging plate 63 and the U-shaped magnetic plate 56, and the converging plate 63 has magnetism. The converging plate 63 is located on the movement track of the U-shaped plate 62.

[0043] The anti-interference device 6 further includes a friction plate 64, a hook-shaped plate 65, a support rod 66 and a turning plate 67. The side of the friction plate 64 close to the U-shaped magnetic plate 56 is slidably installed on the outer wall of the converging plate 63. The hook-shaped plate 65 is hinged between the outer wall of the friction plate 64 and the outer wall of the U-shaped magnetic plate 56. Both ends of the support rod 66 are fixedly installed on the inner wall of the return groove of the U-shaped magnetic plate 56. The inner part of the turning plate 67 is rotationally installed on the outer wall of the support rod 66 through a torsion spring. The turning plate 67 is located on the movement track of the side of the U-shaped plate 62 close to the penetrating rod 55, and a detection component is built in the turning plate 67. Through the above cooperation, the turning angle and turning amplitude of the converging plate 63 are effectively limited, avoiding the phenomenon that the converging plate 63 is damaged by being folded back under the influence of the fluid during the turning process. At the same time, the metal content in the cold flow is monitored in real time by the turning plate 67 and the detection component, and information is transmitted through the intelligent information module, facilitating the staff to judge whether the overall equipment needs to be cleaned and maintained.

[0044] During use, when the anti-slip wheel 57 rotates, it drives the reciprocating lead screw 61 to rotate. When the reciprocating lead screw 61 rotates, it drives the built-in block of the U-shaped plate 62 through the reciprocating spiral groove on its outer wall. At this time, under the limitation of the U-shaped magnetic plate 56, the U-shaped plate 62 can slide along the outer wall of the reciprocating lead screw 61. When the U-shaped plate 62 slides vertically away from the through rod 55, the U-shaped plate 62 will contact the inner wall of the converging plate 63 and generate a contact force. At this time, the converging plate 63 rotates away from the through rod 55 with its hinge axis as the center. After that, the converging plate 63 is reset by the torsion spring. Through the above cooperation, the converging plate 63 pats the cold flow during the flowing process, promoting the cold flow to surge towards the direction close to the U-shaped magnetic plate 56, and adsorbing and removing the metal components contained in the cold flow by means of the magnetic property of the U-shaped magnetic plate 56 and itself, preventing the metal components in the cold flow from directly flushing and covering the outer wall of the graphite tube bundle 31 and interfering with the heat conduction characteristics of the graphite tube bundle 31; when the converging plate 63 rotates, it drives the friction plate 64 to move synchronously. The friction plate 64 is limited by the hook-shaped plate 65, prompting the hinge axis of the friction plate 64 to start rotating. The hook-shaped plate 65 pushes the friction plate 64 to slide along the outer wall of the converging plate 63. When the friction plate 64 slides to the maximum sliding range, it will contact the hook-shaped plate 65 and cause deformation. At this time, the hook-shaped plate 65 limits the friction plate 64, and the friction plate 64 limits the rotation angle of the converging plate 63. When the U-shaped plate 62 slides towards the through rod 55, it contacts and presses the turning plate 67. The turning plate 67 can turn upwards along the outer wall of the support rod 66 under the limitation of the support rod 66. During the process of the turning plate 67 turning upwards, it contacts the cold flow, and the turning plate 67 detects the metal content in the cold flow through the built-in detection component. Through the above cooperation, the rotation angle and rotation amplitude of the converging plate 63 are effectively limited, avoiding the phenomenon that the converging plate 63 is damaged by folding back under the influence of the fluid during the rotation process. At the same time, the metal content in the cold flow is monitored in real time by relying on the turning plate 67 and the detection component, and the information is transmitted through the intelligent information module, which is convenient for the staff to judge whether the overall equipment needs to be cleaned and maintained.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
