[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] When existing thermal oil heating units heat thermal oil, some of the heat from the heating tubes and heating structure dissipates into the interior of the device casing, causing the internal temperature of the casing to gradually rise. This can easily damage the mechanical parts inside the casing, thereby reducing the effectiveness of the existing thermal oil heating units.

[0022] In view of this, the present invention provides a heat transfer oil heating host for a heat transfer oil heat exchanger unit in a chemical production line. It solves the problem of achieving internal cooling of the outer shell through the cooperation of a fan, housing, motor, lead screw, lead screw nut, baffle, exhaust pipe and monitoring unit. It also solves the problem that in existing heat transfer oil heating hosts, when heating heat transfer oil, some heat from the heating pipe and heating structure is dissipated into the interior of the device shell, causing the internal temperature of the device shell to gradually rise, which can easily damage the mechanical parts inside the shell and reduce the performance of the existing heat transfer oil heating host.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1: By Figure 1-4It is known that a heat transfer oil heating unit for a chemical production line includes a housing 1. A heating rod 2, model YGW-3, is fixedly connected to the inner wall of the housing 1. When the operator starts the heating rod 2, a heating tube 4 is attached to its surface. The heat transfer oil enters the heating tube 4 through a flow mechanism 3. At this time, the heat generated by the heating rod 2 is transferred to the heating tube 4 through heat transfer. The heat on the heating tube 4 is then transferred to the heat transfer oil inside, heating the heat transfer oil. A cover plate 7 is fixedly connected to the front of the housing 1 by bolts. The operator can access the internal parts of the housing 1 by disassembling the cover plate 7. For inspection and maintenance, the heat transfer oil heating unit of the chemical production line also includes a flow mechanism 3, a cooling mechanism 5, and a filtration mechanism 6. The flow mechanism 3 is located inside the outer shell 1; the cooling mechanism 5 is located outside the outer shell 1; the cooling mechanism 5 cools the temperature inside the outer shell 1 to prevent the temperature inside the outer shell 1 from becoming too high; the filtration mechanism 6 is located on one side of the outer shell 1; the filtration mechanism 6 filters impurities inside the heat transfer oil. Specifically, the flow mechanism 3 allows the cooled heat transfer oil inside the heat exchange unit to flow into the heating tube 4 for heating, the cooling mechanism 5 cools the inside of the outer shell 1, and the filtration mechanism 6 filters the heat transfer oil that needs to be heated.

[0025] In the specific implementation process, it is worth noting that the heating rod 2 is model YGW-3. When the operator starts the heating rod 2, the heat transfer oil enters the heating tube 4 through the circulation mechanism 3. At this time, the heat generated by the heating rod 2 is transferred to the heating tube 4 through heat transfer. The heat on the heating tube 4 is then transferred to the heat transfer oil inside, heating the heat transfer oil. The cooling mechanism 5 cools down the temperature inside the outer shell 1 to prevent the temperature inside the outer shell 1 from being too high. The filtering mechanism 6 filters the impurities inside the heat transfer oil. The cover plate 7 is fixed to the front of the outer shell 1 by bolts. By disassembling the cover plate 7, the operator can inspect and repair the parts inside the outer shell 1.

[0026] Specifically, the staff starts the heating rod 2, and the heat transfer oil enters the heating tube 4 through the circulation mechanism 3. At this time, the heat generated by the heating rod 2 is transferred to the heating tube 4 through heat transfer. The heat on the heating tube 4 is then transferred to the heat transfer oil inside, heating the heat transfer oil. The cooling mechanism 5 cools down the temperature inside the outer shell 1 to prevent the temperature inside the outer shell 1 from getting too high. The filtering mechanism 6 filters the impurities inside the heat transfer oil. The cover plate 7 is fixed to the front of the outer shell 1 with bolts. The staff can inspect and repair the parts inside the outer shell 1 by disassembling the cover plate 7.

[0027] Example 2: From Figure 1-4It can be seen that the cooling mechanism 5 includes a fan 51, a housing 52, a motor 53, a lead screw 54, a lead screw nut 55, a baffle 56, an exhaust pipe 57, and a monitoring unit 58. The fan 51 consists of a dustproof net, a fan, and an air inlet pipe. The air inlet pipe is connected to the bottom of the housing 1. The inner wall of the air inlet pipe is equipped with a dustproof net and a fan. The motor 53 is a Y90S-4 model. The fan 51 is fixedly connected to the bottom of the housing 1. The housing 52 is fixedly connected to the top of the housing 1. The motor 53 is fixedly connected to one side of the housing 52. Both ends of the lead screw 54 are rotatably connected to the inner wall of the housing 52 via bearings, and both ends extend to the outside of the housing 52, with one end fixed to the output shaft of the motor 53. When the temperature inside the housing 1 is too high, the motor 53 is started, and the motor 53 drives the lead screw 54 to rotate. The lead screw nut 55 is threadedly connected to the outer wall of the lead screw 54, and the lead screw 54 drives the lead screw nut 55 to move. The bottom of the nut 55 is slidably engaged with the bottom of the inner wall of the housing 52, and the top extends to the outside of the housing 52. The lead screw nut 55 is located within the inner wall of the housing 52. The limit groove slides to guide the lead screw nut 55, and the baffle 56 is fixedly connected to the top of the lead screw nut 55; the lead screw nut 55 drives the baffle 56 to move, and the baffle 56 moves on the exhaust pipe 57. When the baffle 56 moves, it moves to the left end of the exhaust pipe 57 and leaves the exhaust pipe 57, opening the exhaust pipe 57 and stopping the motor 53. The exhaust pipe 57 is connected to the upper part of the outer casing 1, and its top is attached to the inner wall of the baffle 56; the fan 51 is started, and the fan 51 allows outside air to enter. Inside the outer casing 1, the hot air inside the outer casing 1 is discharged through the exhaust pipe 57 to cool the interior of the outer casing 1. After cooling is completed, the fan 51 is stopped, and the motor 53 rotates in the opposite direction, thereby causing the baffle 56 to return to its initial position and closing the exhaust pipe 57 to prevent dust from entering the interior of the outer casing 1. The monitoring unit 58 is set on the outer wall of the outer casing 1. The lead screw 54, driven by the motor 53, causes the lead screw nut 55 to drive the baffle 56 to open the exhaust pipe 57, and the fan 51 causes the air inside the outer casing 1 to flow.

[0028] In the specific implementation process, it is worth noting that the fan 51 consists of a dust filter, a fan, and an intake pipe. The intake pipe is connected to the bottom of the outer casing 1, and the inner wall of the intake pipe is equipped with a dust filter and a fan. The motor 53 is a Y90S-4 model. When the temperature inside the outer casing 1 is too high, the motor 53 is started. The motor 53 drives the lead screw 54 to rotate, and the lead screw 54 drives the lead screw nut 55 to move. The lead screw nut 55 slides on the limiting groove in the inner wall of the housing 52, guiding the lead screw nut 55. The lead screw nut 55 drives the baffle 56 to move, and the baffle 56 moves on the exhaust pipe 5. 7. When moving, the baffle 56 moves to the left end of the exhaust pipe 57 and leaves the exhaust pipe 57, opening the exhaust pipe 57, stopping the motor 53, and starting the fan 51. The fan 51 allows outside air to enter the interior of the outer casing 1, and exhausts the hot air inside the outer casing 1 through the exhaust pipe 57, cooling the interior of the outer casing 1. After cooling is completed, the fan 51 is stopped, and the motor 53 rotates in the opposite direction, so that the baffle 56 returns to the initial position, closing the exhaust pipe 57 to prevent dust from entering the interior of the outer casing 1, thus achieving cooling of the interior of the outer casing 1.

[0029] Furthermore, the monitoring unit 58 includes a temperature sensor 581, a controller 583, and an alarm 582. The temperature sensor 581 is a PT100 platinum resistance temperature sensor, with a measurement range typically from -200℃ to 650℃, which can well meet the needs of internal temperature monitoring of the enclosure 1. The controller 583 is an S7-200 SMART PLC, and the alarm 582 is an LTE-1101J. The temperature sensor 581 is connected to the controller 583 via a three-wire connection to the analog input module of the controller 583. The three-wire connection can effectively reduce the influence of wire resistance on the measurement results and improve measurement accuracy. The alarm 582 is connected to the controller 583 via a digital output interface. The controller 583 is connected to the motor 53 via a contactor connected to the digital output port of the controller 583. The controller 583 outputs a control signal according to the temperature, controlling the coil of the contactor to be energized or de-energized, thereby controlling the motor 53. The controller 583 is connected to the fan 51 via a contactor to start and stop the fan. The fan 51 is connected to the digital output port of the controller 583. The temperature sensor 581 is fixedly connected to the top of the inner wall of the housing 1 with bolts. The controller 583 is fixedly connected to the side wall of the housing 1. When the temperature sensor 581 detects that the temperature inside the housing 1 is higher than the set value, the temperature sensor 581 transmits a signal to the controller 583, which in turn transmits the signal to the alarm 582. The alarm 582 sounds to remind the operator that the temperature inside the housing 1 is too high, and the operator stops the heating of the heat transfer oil. The alarm 582 is fixedly connected to the other side of the housing 1 away from the controller 583 with bolts. The controller 583 transmits a signal to the motor 53 and the fan 51, which then operate. When the temperature inside the housing 1 drops to the specified value, the controller 583 stops the operation of the motor 53 and the fan 51. The internal temperature of the housing 1 is monitored through the cooperation of the temperature sensor 581, the controller 583, and the alarm 582.

[0030] In the specific implementation process, it is worth noting that the temperature sensor 581 is a PT100 platinum resistance temperature sensor, with a measurement range typically from -200℃ to 650℃, which can well meet the needs of internal temperature monitoring of the enclosure 1. The controller 583 is an S7-200 SMART PLC, and the alarm 582 is an LTE-1101J. The temperature sensor 581 is typically connected to the analog input module of the controller 583 using a three-wire connection. The three-wire connection can effectively reduce the influence of wire resistance on the measurement results and improve measurement accuracy. The alarm 582 is connected to the controller 583 through a digital output interface. The controller 583 is connected to the motor 53 via a contactor to the digital output port of the controller 583. Controller 583 outputs a control signal based on temperature conditions to energize or de-energize the coil of the contactor, thereby controlling the start and stop of motor 53. The connection between controller 583 and fan 51 is as follows: fan 51 is connected to the digital output port of controller 583 via a contactor. When temperature sensor 581 detects that the temperature inside the casing 1 is higher than the set value, temperature sensor 581 transmits a signal to controller 583. Controller 583 transmits the signal to alarm 582, which sounds to remind staff that the temperature inside the casing 1 is too high. Staff then stop the heating of the heat transfer oil. Controller 583 transmits a signal to motor 53 and fan 51, and motor 53 and fan 51 begin operation. When the temperature inside the casing 1 drops to the specified value, controller 583 stops the operation of motor 53 and fan 51, thus achieving automatic monitoring of the temperature inside the casing 1 and timely cooling.

[0031] Furthermore, the filtration mechanism 6 includes a filter box 61, a cover 62, a filter element 63, a sealing ring 64, and a fixing part 65. The filter box 61 is fixedly connected to the inner wall of the outer shell 1, and extends to the inside and outside of the outer shell 1 on both sides respectively. The cover 62 is inserted into the outer wall of the filter box 61. The filter element 63 is fixedly connected to the inner wall of the cover 62 by bolts. When the operator moves the cover 62, the cover 62 moves the filter element 63, placing the filter element 63 into the filter box 61. The cover 62 is then inserted into the filter box 61. The sealing ring 64 is fixedly connected to the inner wall of the cover 62, and its outer wall is in contact with the outer wall of the filter box 61. The sealing ring 64 improves the sealing between the cover 62 and the filter box 61. The fixing part 65 has four sets, all located outside the cover 62. The filter element 63, driven by the cover 62, enters the filter box 61 to filter the heat transfer oil.

[0032] In the specific implementation process, it is worth noting that when the staff moves the box cover 62, the box cover 62 moves the filter element 63, puts the filter element 63 into the filter box 61, inserts the box cover 62 into the filter box 61, and the sealing ring 64 improves the sealing between the box cover 62 and the filter box 61, so as to filter the impurities inside the heat transfer oil through the filter element 63.

[0033] Furthermore, the fixing part 65 includes a curved column 651, a threaded column 652, and a connecting plate 653. The end of the curved column 651 is fixedly connected to one side of the outer casing 1 near the outer wall of the filter box 61. The threaded column 652 is threadedly connected to the inner wall of the curved column 651. After the box cover 62 is inserted into the filter box 61, the operator rotates the threaded column 652 in sequence. The threaded column 652 rotates in the curved column 651, which is L-shaped. The connecting plate 653 is fixedly connected to the outer wall of the threaded column 652, and one side is attached to the outer wall of the box cover 62. The threaded column 652 drives the connecting plate 653 to rotate and move, slowly approaching the box cover 62. When the threaded column 652 drives the connecting plate 653 to rotate 90 degrees, the connecting plate 653 and the box cover 62 are tightly fitted together. After completion, the operator stops rotating the threaded column 652. Under the drive of the threaded column 652, the connecting plate 653 rotates and moves, fixing the box cover 62 to the filter box 61.

[0034] In the specific implementation process, it is worth noting that after the cover 62 is inserted into the filter box 61, the staff rotates the threaded column 652 in sequence. The threaded column 652 rotates in the curved column 651, which is L-shaped. The threaded column 652 drives the connecting plate 653 to rotate and move at the same time, slowly approaching the cover 62. When the threaded column 652 drives the connecting plate 653 to rotate 90 degrees, the connecting plate 653 and the cover 62 are tightly fitted together. After completion, the staff stops rotating the threaded column 652, thus fixing the cover 62.

[0035] Furthermore, the heating mechanism 3 includes an oil inlet pipe 31, a first connecting pipe 32, an oil pump 33, a second connecting pipe 34, and an oil outlet pipe 35. The oil pump 33 is a Y100-65-200 model with a maximum operating temperature of 350℃. The oil pump 33 is connected to the controller 583 by means of a cable connecting the output of the controller 583 to the motor driver of the oil pump 33. The wires in the cable are connected to the control signal output pin of the controller 583 and the corresponding input pin of the motor driver of the oil pump 33 to transmit control signals and control the start, stop, and speed adjustment of the oil pump 33. The oil inlet pipe 31 is connected to the inner wall of the cover 62. When the operator starts the oil pump 33 through the controller 583, the heat transfer oil cooled down inside the heat exchange unit enters the filter element 63 through the oil inlet pipe 31 for processing. The filter is constructed by connecting the first connecting pipe 32 to the inner wall of the filter box 61; the input end of the oil pump 33 is connected to the end of the first connecting pipe 32; the two ends of the second connecting pipe 34 are connected to the output end of the oil pump 33 and the oil inlet end of the heating pipe 4, respectively; the oil outlet pipe 35 is connected to the inner wall of the outer shell 1, extends to the interior of the outer shell 1, and is connected to the oil outlet end of the heating pipe 4; after filtration, the oil enters the second connecting pipe 34 through the first connecting pipe 32, and then enters the heating pipe 4 for heating. The heated heat transfer oil re-enters the heat exchange unit through the oil outlet pipe 35. Under the drive of the oil pump 33, the heat transfer oil enters the first connecting pipe 32 through the oil inlet pipe 31, then enters the heating pipe 4 through the second connecting pipe 34 for heating, and finally the heated heat transfer oil enters the interior of the heat exchange unit through the oil outlet pipe 35.

[0036] In the specific implementation process, it is worth noting that the oil pump 33 is model Y100-65-200, with a maximum operating temperature of 350℃. The connection between the oil pump 33 and the controller 583 is as follows: the output end of the controller 583 is connected to the motor driver of the oil pump 33 via a cable. The wires in the cable are connected to the control signal output pin of the controller 583 and the corresponding input pin of the motor driver of the oil pump 33 to transmit control signals and realize the control of the oil pump 33, such as starting, stopping, and speed adjustment. When the operator starts the oil pump 33 through the controller 583, the heat transfer oil cooled down inside the heat exchange unit enters the filter element 63 through the oil inlet pipe 31 for filtration. After filtration, it enters the second connecting pipe 34 through the first connecting pipe 32 and then enters the heating pipe 4 for heating. The heated heat transfer oil re-enters the heat exchange unit through the oil outlet pipe 35 to realize the heating of the heat transfer oil.

[0037] Specifically, first, the operator moves the cover 62, which moves the filter element 63, placing it into the filter box 61. Then, the operator inserts the cover 62 into the filter box 61. Next, the operator rotates the threaded column 652 sequentially. The threaded column 652 rotates within the crank column 651, causing the connecting plate 653 to rotate and move, slowly approaching the cover 62. When the threaded column 652 rotates the connecting plate 653 ninety degrees, the connecting plate 653 and the cover 62 are tightly fitted together. After this process, the operator... Stop rotating the threaded column 652. When heating of the heat transfer oil is required, the operator starts the oil pump 33 via the controller 583. At this time, the heat transfer oil cooled down inside the heat exchange unit enters the filter element 63 through the oil inlet pipe 31 for filtration. After filtration, it enters the second connecting pipe 34 through the first connecting pipe 32, and then enters the heating pipe 4 for heating. The heated heat transfer oil re-enters the heat exchange unit through the oil outlet pipe 35. When the temperature sensor 581 detects that the temperature inside the outer casing 1 is higher than the set value, Temperature sensor 581 transmits a signal to controller 583, which in turn transmits the signal to alarm 582. Alarm 582 sounds an alarm to alert staff that the internal temperature of casing 1 is too high, prompting staff to stop heating the heat transfer oil. Controller 583 then transmits a signal to motor 53 and fan 51, which begin operating. Motor 53 drives lead screw 54 to rotate, which in turn moves lead screw nut 55. Lead screw nut 55 slides in a limiting groove on the inner wall of housing 52. The lead screw nut 55 drives the baffle 56 to move. The baffle 56 moves on the exhaust pipe 57, opening the exhaust pipe 57, stopping the motor 53, and starting the fan 51. The fan 51 allows outside air to enter the interior of the outer casing 1, expelling the hot air inside the outer casing 1 through the exhaust pipe 57, thus cooling the interior of the outer casing 1. When the temperature inside the outer casing 1 drops to a specified value, the motor 53 rotates in the opposite direction, causing the baffle 56 to return to its initial position, closing the exhaust pipe 57, and the controller 583 stops the operation of the motor 53 and the fan 51.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
