Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, in particular to an integral graphite birdcage graphite heat exchanger. Background Art

[0002] Graphite heat exchanger usually refers to a heat exchanger whose heat transfer components are made of graphite. Graphite heat exchanger relies on graphite's acid corrosion resistance and good thermal conductivity to make graphite into a flow guide 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 achieving heat exchange.

[0003] The patent with the patent announcement number CN211261935U discloses an integral graphite birdcage graphite heat exchanger, which includes an upper head and a lower head; the heat exchanger also includes a graphite cylinder, the upper head is bonded and 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 bonded and 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; the graphite cylinder is provided with several transverse through holes and several longitudinal through holes, the transverse through holes horizontally penetrate the side wall of the graphite cylinder, the direction of the transverse through holes is offset by an angle from the center of the graphite cylinder, all the transverse through holes are divided into several rows, arranged in a circle, the longitudinal through holes vertically penetrate the upper and lower end faces of the graphite cylinder, connecting the upper chamber with the lower chamber, all the longitudinal through holes are divided into several groups, each group of longitudinal through holes is located between two adjacent rows of transverse through holes, and is evenly distributed; all the upper chambers and all the lower chambers are connected in series through the longitudinal through holes to form a loop. The integral graphite cylinder design is adopted, which is convenient for workers to operate and has high heat exchange efficiency.

[0004] However, the device still has some shortcomings: the device is easy to operate and has high heat exchange efficiency, but during long-term use, water droplets are easily generated inside the heat exchanger due to the intersection of cold and hot 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, thereby increasing the chance of damage to the heat exchanger, which can easily reduce the durability of the heat exchanger to a certain extent. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an integral graphite birdcage graphite heat exchanger, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an integral graphite birdcage graphite heat exchanger, comprising a support assembly, a heat exchange assembly is arranged on the top of the support assembly, a sealing end is arranged on the right side of the heat exchange assembly, and a plurality of circulation pipes are symmetrically and fixedly installed on the outer wall of the left end of the heat exchange assembly, a cold water pipe is arranged on the left end of the heat exchange assembly, a heat flow pipe is arranged on the bottom of the right end of the heat exchange assembly, two tube sheets are arranged inside the heat exchange assembly, the two tube sheets are symmetrically distributed around the center of the heat exchange assembly, a graphite tube bundle is arranged inside the tube sheet, and a baffle is arranged on the outer wall of the graphite tube bundle; An anti-oxidation device is provided at the left end inside the heat exchange component, an anti-delay device is provided inside the anti-oxidation device, and an anti-interference device is provided inside the anti-delay device; The anti-oxidation device includes an electric slide rail, which is arranged at the left end inside the heat exchange component, and the left side of the tube plate located at the left end is fixedly connected to the right side of the electric slide rail, and a transmission rod is slidably installed inside the electric slide rail, and the transmission rod is located on the left side of the electric slide rail, and a filter plate is fixedly installed on the side of the transmission rod close to the cold water pipe, and the filter plate and the transmission rod are non-concentrically connected, the outer wall of the filter plate contacts the inner wall of the heat exchange component, and a plurality of transmission rollers are equidistantly and rotatably installed on the edge of the filter plate close to the cold water pipe, and a cross bar is fixedly installed on the side of the transmission roller close to the cold water pipe, and a reciprocating spiral groove is provided on the outer wall of the cross bar, and a push ring is movably installed on the outer wall of the reciprocating spiral groove of the cross bar, and the push ring is fixedly installed on the sieve plate close to the cold water pipe, and a limiting rod is fixedly installed at the center of the filter plate close to the cold water pipe, and cold flow is injected through the cold water pipe, and hot flow is injected into the hot flow pipe, and the cold flow and hot flow enter the interior of the heat exchange component. After that, heat exchange is carried out through the graphite tube bundle, and the tube sheet limits and seals the graphite tube bundle. At the same time, the baffle improves the heat transfer coefficient of the graphite tube bundle, and relies on the good conductivity of graphite and the conduction of the baffle to ensure the good heat exchange efficiency of the heat exchange component; before the cold flow enters the heat exchange component, the electric slide rail is started, and the electric slide rail drives the transmission rod to revolve inside itself, and the transmission rod drives the filter plate to revolve along the inner wall of the heat exchange component. When the filter plate revolves, it drives the transmission roller to revolve, and when the transmission roller revolves, it contacts the inner wall of the heat exchange component to generate friction. The transmission roller starts to rotate by friction and drives the cross bar to rotate. When the cross bar rotates, the reciprocating spiral groove on its outer wall limits the built-in block of the push ring, so that the push ring can slide horizontally along the outer wall of the cross bar toward the cold water pipe and reset, and the push ring pushes the screen plate to slide synchronously along the outer wall of the limit rod.

[0007] According to the above technical solution, the outer walls of several of the transmission rollers are in contact with the inner wall of the heat exchange component, and a transmission groove is opened inside the transmission roller. The sieve plate is located on the left side of the filter plate, and the outer wall of the limit rod is slidably installed inside the sieve plate.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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 gathering plate and the U-shaped magnetic plate, and the gathering plate is magnetic, and the gathering plate is located on the movement trajectory of the U-shaped plate.

[0013] According to the above technical scheme, the anti-interference device also includes a friction plate, a hook plate, a support rod and a flip plate. The friction plate is slidably installed on the outer wall of the gathering plate close to one side of the U-shaped magnetic plate. The hook 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's circular groove. The flip plate is rotatably installed on the outer wall of the support rod through a torsion spring. The flip plate is located on the motion trajectory of the U-shaped plate close to the through-rod side, and a detection component is built into the flip plate. When the gathering plate flips, it drives the friction plate to move synchronously. The friction plate passes The hook plate limits the position, causing the hinge shaft of the friction plate to start rotating, and the hook plate pushes the friction plate to slide along the outer wall of the gathering plate. When the friction plate slides to the maximum sliding range, it will resist the hook plate and deform. At this time, the hook plate limits the friction plate, and the friction plate limits the flipping angle of the gathering plate. When the U-shaped plate slides toward the direction close to the through rod, it contacts and presses the flip plate. The flip plate is limited by the support rod to enable itself to flip upward along the outer wall of the support rod. During the process of flipping upward, the flip plate comes into contact with the cold flow, and the flip plate detects the metal content in the cold flow through the built-in detection component.

[0014] The present invention provides an integral graphite birdcage graphite heat exchanger having the following beneficial effects: (1) The present invention adopts the setting of the anti-oxidation device, and cooperates with the electric slide rail, the transmission rod, the filter plate, the transmission roller, the cross bar, the push ring, the screen plate and the limit rod. The filter plate is rotated to preheat the cold flow, thereby preventing water droplets from adhering to the inner wall of the heat exchange component due to the large temperature difference when the cold flow and the hot flow are directly exchanged with each other, and preventing the water droplets from accelerating the oxidation rate of the inner wall of the heat exchange component during the drying process, thereby reducing the durability of the heat exchange component; at the same time, the interlayer between the screen plate and the filter plate is used to further remove the impurity particles in the cold flow, and the reciprocating sliding of the screen plate enables the impurities to be more evenly distributed to prevent the filter holes from being blocked, thereby effectively preventing the impurities from adhering to and solidifying inside the heat exchange component to reduce the smoothness of the inner wall, and preventing the oxidation phenomenon from being aggravated due to the unevenness of the inner wall of the heat exchange component.

[0015] (2) The present invention sets an anti-delay device, and 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. The friction cotton roller revolves and rotates. In the process of the round rod disturbing the cold flow for uniform heat exchange, the friction cotton roller relies on deformation and rotation to wipe off the solidified impurities on the surface of the filter plate, thereby preventing excessive dirt and impurities from adhering to the surface of the filter plate during long-term use, and preventing the exchange process between the cold flow and the hot flow from being delayed, resulting in a decrease in heat exchange efficiency; and effectively reducing the friction loss of the U-shaped magnetic plate. At the same time, the U-shaped magnetic plate is used to stir the cold flow for the second time to prevent the cold flow from gathering and pouring in, which makes it difficult for the central part of the cold flow to exchange heat in time, thereby increasing energy loss.

[0016] (3) The present invention sets an anti-interference device, cooperates with an anti-slip wheel, a reciprocating screw, a U-shaped plate, a gathering plate, a friction plate, a hook plate, a support rod and a flip plate, and relies on the gathering plate to beat the cold flow in the flow process, so as to cause the cold flow to surge toward the U-shaped magnetic plate. The U-shaped magnetic plate and its own magnetism are used to adsorb and remove the metal components contained in the cold flow, thereby preventing the metal components in the cold flow from directly washing and covering the outer wall of the graphite tube bundle and interfering with the thermal conductivity of the graphite tube bundle; and effectively limits the flipping angle and flipping amplitude of the gathering plate, thereby preventing the gathering plate from being affected by the fluid and being damaged by the back bending during the flipping process. At the same time, the metal content in the cold flow is monitored in real time by relying on the flipping plate and the detection component, and information is transmitted through the intelligent information module, so that the staff can judge whether the equipment as a whole needs to be cleaned and maintained.

A transmission rod 42 is slidably installed inside the electric slide rail 41, and 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 filter plate 43 and the transmission rod 42 are non-concentrically connected. The outer wall of the filter plate 43 contacts the inner wall of the heat exchange component 2, and a plurality of transmission rollers 44 are equidistantly and rotatably installed at 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, and a reciprocating spiral groove is opened 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. The push ring 46 is close to the cold water pipe 21. The filter plate 43 is fixedly installed on the side of the filter plate 43, and a limit rod 48 is fixedly installed at the center of one side of the cold water pipe 21. Through the above cooperation, the cold flow is preheated by the revolution of the filter plate 43 to prevent water droplets from adhering to the inner wall of the heat exchange component 2 due to excessive temperature difference when the cold flow and the hot flow are directly exchanged with each other, and to avoid the water droplets accelerating the oxidation rate of the inner wall of the heat exchange component 2 during the process of heat drying, thereby reducing the durability of the heat exchange component 2; through the above cooperation, the interlayer between the sieve plate 47 and the filter plate 43 is relied on to further remove impurity particles in the cold flow, 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 preventing impurities from adhering to and solidifying inside the heat exchange component 2 to reduce the smoothness of the inner wall, and avoiding the oxidation phenomenon caused by the unevenness of the inner wall of the heat exchange component 2.

[0021] The outer walls of the plurality of transmission rollers 44 are in contact with the inner wall of the heat exchange assembly 2 , and a transmission groove is provided inside the transmission rollers 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 .

[0022] During use, a cold flow is injected through the cold water pipe 21, and a hot flow is injected through the hot flow pipe 22. After the cold flow and the hot flow enter the interior of the heat exchange component 2, heat exchange 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 32 improves the heat transfer coefficient of the graphite tube bundle 31. The good conductivity of graphite and the conduction of the baffle 32 ensure the good heat exchange efficiency of the heat exchange component 2. Before the cold flow enters the interior of the heat exchange component 2, the electric slide rail 41 is started, and 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 to block the cold flow entering the interior of the heat exchange component 2. Through the above cooperation, the cold flow is preheated by the revolution of the filter plate 43 to prevent water droplets from adhering to the inner wall of the heat exchange component 2 due to excessive temperature difference when the cold flow and the hot flow are directly exchanged, so as to prevent the water droplets from being dried by heat. The process accelerates the oxidation speed of the inner wall of the heat exchange component 2, thereby reducing the durability of the heat exchange component 2; when the filter plate 43 revolves, it drives the transmission roller 44 to revolve, and when the transmission roller 44 revolves, it contacts the inner wall of the heat exchange component 2 to generate friction. The transmission roller 44 starts to rotate by the friction and drives the cross bar 45 to rotate. When the cross bar 45 rotates, the reciprocating spiral groove on its outer wall restricts the built-in block of the push ring 46, so that the push ring 46 can slide horizontally along the outer wall of the cross bar 45 toward 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 limit rod 48. Through the above cooperation, the interlayer between the sieve plate 47 and the filter plate 43 is relied on to further remove impurity particles in the cold flow, and the reciprocating sliding of the sieve plate 47 enables impurities to be more evenly distributed to prevent clogging of the filter holes, effectively preventing impurities from adhering to and solidifying inside the heat exchange component 2 to reduce the smoothness of the inner wall, and preventing the oxidation phenomenon from being aggravated due to the unevenness of the inner wall of the heat exchange component 2.

[0023] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-delay device 5; 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. The transmission belt 51 is internally installed in the transmission groove of the transmission roller 44 at one end close to the inner wall of the heat exchange component 2. The rotating column 52 is rotatably installed on the left side of the filter plate 43 away from the screen plate 47. The 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, the friction cotton roller 54 relies on the revolution and rotation of the friction cotton roller 54. In 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, so as to avoid excessive adhesion of dirt and impurities on the surface of the filter plate 43 during long-term use, and to prevent the exchange process of cold flow and hot flow from being delayed, resulting in reduced heat exchange efficiency.

[0024] The outer wall of the rotating column 52 is drivingly connected to one end of the transmission belt 51 away from the inner wall of the heat exchange component 2 , and a plurality of round rods 53 are evenly distributed on the outer wall of the rotating column 52 , and the outer wall of the friction cotton roller 54 contacts the left side of the filter plate 43 .

[0025] The anti-delay device 5 also includes a through rod 55, a U-shaped magnetic plate 56 and an anti-skid wheel 57. The left end of the through rod 55 passes through 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 circular groove is opened inside the U-shaped magnetic plate 56. The anti-skid wheel 57 is rotatably installed on the inner wall of the U-shaped magnetic plate 56 away from the through rod 55. The outer wall of the anti-skid wheel 57 contacts the right side of the filter plate 43. The above cooperation effectively reduces the friction loss of the U-shaped magnetic plate 56. At the same time, the U-shaped magnetic plate 56 is used to stir the cold flow for the second time to avoid the cold flow from gathering and pouring in, which makes it difficult for the central part of the cold flow to exchange heat in time, thereby increasing energy loss.

[0026] When in use, when the transmission roller 44 rotates, the transmission belt 51 drives the rotating column 52 to rotate along the left outer wall of the filter plate 43. 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 solidified impurity particles are 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 is deformed by the friction 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, in 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, so as to avoid the filter plate 43 from being used for a long time. Too much dirt and impurities adhere to its surface, which prevents the exchange process between the cold flow and the hot flow from being delayed, resulting in a decrease in heat exchange efficiency; when the rotating column 52 rotates, it drives the through rod 55 to rotate, and 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-skid wheel 57 to move synchronously along the right outer wall of the filter plate 43, and the anti-skid wheel 57 starts to rotate due to the friction between the filter plate 43, thereby the anti-skid wheel 57 converts the sliding friction between the U-shaped magnetic plate 56 and the filter plate 43 into rolling friction. The above cooperation effectively reduces the friction loss of the U-shaped magnetic plate 56, and at the same time relies on the U-shaped magnetic plate 56 to perform secondary stirring on the cold flow to avoid the cold flow from gathering and pouring in, which makes it difficult for the central part of the cold flow to exchange heat in time, thereby increasing energy loss.

[0027] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-interference device 6; The anti-interference device 6 includes a reciprocating screw rod 61, a U-shaped plate 62 and a gathering plate 63. Both ends of the reciprocating screw rod 61 are fixedly installed at the center of the inner wall of the anti-skid wheel 57. The end of the U-shaped plate 62 close to the filter plate 43 is movably installed inside the outer wall of the reciprocating screw rod 61. The gathering plate 63 is hinged to the outer wall of the U-shaped magnetic plate 56 away from the through rod 55. Through the above cooperation, the gathering plate 63 is used to flap the cold flow in the flow process, so that the cold flow is urged to surge toward the direction close to the U-shaped magnetic plate 56. The U-shaped magnetic plate 56 and its own magnetism are used to adsorb and remove the metal components contained in the cold flow, so as to prevent the metal components in the cold flow from directly scouring and covering the outer wall of the graphite tube bundle 31 and interfering with the thermal conductivity of the graphite tube bundle 31.

[0028] The inner wall of the U-shaped plate 62 is slidably mounted on the side of the U-shaped magnetic plate 56 close to the filter plate 43 . A torsion spring is arranged between the gathering plate 63 and the U-shaped magnetic plate 56 . The gathering plate 63 is magnetic and is located on the movement trajectory of the U-shaped plate 62 .

[0029] The anti-interference device 6 also includes a friction plate 64, a hook plate 65, a support rod 66 and a flip plate 67. The friction plate 64 is slidably installed on the outer wall of the gathering plate 63 near the side of the U-shaped magnetic plate 56. The hook 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 circular groove of the U-shaped magnetic plate 56. The inside of the flip plate 67 is rotatably installed on the outer wall of the support rod 66 through a torsion spring. The flip plate 67 is located on the movement trajectory of the U-shaped plate 62 near the side of the through rod 55, and the flip plate 67 has a built-in detection component. The above cooperation effectively limits the flip angle and flip amplitude of the gathering plate 63 to prevent the gathering plate 63 from being damaged by the fluid during the flipping process. At the same time, the metal content in the cold flow is monitored in real time by relying on the flip plate 67 and the detection component, and information is transmitted through the intelligent information module, which is convenient for the staff to judge whether the equipment as a whole needs cleaning and maintenance.

[0030] When in use, the anti-skid wheel 57 rotates and drives the reciprocating screw rod 61 to rotate. When the reciprocating screw rod 61 rotates, the reciprocating spiral groove on its outer wall drives the built-in block of the U-shaped plate 62. At this time, the U-shaped plate 62 is limited by the U-shaped magnetic plate 56, so that it can slide along the outer wall of the reciprocating screw rod 61. When the U-shaped plate 62 slides vertically in the direction away from the through-rod 55, the U-shaped plate 62 will resist the inner wall of the gathering plate 63 to generate a resistance force. At this time, the gathering plate 63 turns over in the direction away from the through-rod 55 with its own hinge axis as the axis. The gathering plate 63 is turned, and then it is reset by the torsion spring. Through the above cooperation, the gathering plate 63 is used to flap the cold flow in the flow process, so that the cold flow surges toward the direction close to the U-shaped magnetic plate 56. The U-shaped magnetic plate 56 and its own magnetism are used to adsorb and remove the metal components contained in the cold flow, so as to prevent the metal components in the cold flow from directly washing and covering the outer wall of the graphite tube bundle 31 and interfering with the thermal conductivity of the graphite tube bundle 31. When the gathering plate 63 is turned over, it drives the friction plate 64 to move synchronously, and the friction plate 64 is limited by the hook plate 65. When the U-shaped plate 62 slides toward the direction close to the through rod 55, it contacts and presses the flip plate 67, and the flip plate 67 is limited by the support rod 66 so that it can flip upward along the outer wall of the support rod 66. During the flipping process of the flip plate 67, it contacts the cold flow, and the flip plate 67 detects the metal content in the cold flow through the built-in detection component. The above cooperation effectively limits the flipping angle and the flipping amplitude of the gathering plate 63, so as to avoid the gathering plate 63 being damaged by the fluid during the flipping process. At the same time, the metal content in the cold flow is monitored in real time by the flip plate 67 and the detection component, and the information is transmitted through the intelligent information module, so that the staff can judge whether the equipment as a whole needs to be cleaned and maintained.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
